The following content combines the figures and the embodiments for detail description of the present invention. It is particularly pointed out that the following embodiments are only used to illustrate the present invention, and they are not used to limit the scope of the present invention. Other embodiments obtained under the premise of without paying creative labor by the person ordinary skill in the art are all belong to the claims of the present invention.
With reference to
Whether the guide rail 1 is formed integrally or the smooth transition connection by multiple rails, it can reduce the wear of a wheel of the transmission apparatus 2 based on increasing the smoothness of the guide rail 1 to increase the service life of the wheel.
It is worth mentioning that the invention does not limit the specific features of the guide rail 1 such as length, width, or hardness, etc. For example, the total length of the guide rail 1 should be flexibly disposed based on a specific situation of the entire transmission system, and when the transmission distance is longer (such as larger factory area), the length of the guide rail 1 is naturally required to be appropriately increased.
In addition, in order to increase the carrying capacity of the guide rail 1, the guide rail 1 can utilize the material with higher hardness such as steel or iron. Of course, when it does not affect the operation of the transmission system, the guide rail 1 can also utilize other materials. The present invention does not specifically limit it.
The above content specifically describes the guide rail 1, and the following content will describe in detail to the transmission apparatus 2 of the transmission system.
The transmission apparatus 2 includes a main body 20 and a main wheel 21 disposed at the bottom of the main body 20, and the main wheel 21 abut to the guide rail 1 so that the transmission apparatus 2 can move along the preset direction of the guide rail 1. There are various fitting ways between the main wheel 21 and the guide rail 1. For example, a rail groove is disposed on the guide rail 1, and the main wheel 21 is embedded into the rail groove for sliding, or the main wheel 21 has a clamping slot for clamping the guide rail 1 to guide the main wheel 21 to slide along the guide rail 1. Under the premise of without paying creative labor, the abutment methods between the other main wheels 21 and the guide rails 1 thought by the person skilled in the art are ail within the claims of the present invention.
The transmission apparatus 2 further includes an auxiliary wheel 22 disposed at the bottom of the main body 20. The auxiliary wheel 22 is disposed adjacent to the main wheel 21 and above the guide rail 1, and the bottom of the auxiliary wheel 22 is higher than the bottom of the main wheels 21 with a predetermined height. When the main wheel 21 is abnormal such as loss and damage, the auxiliary wheel 22 can support the entire transmission apparatus 2 to continue operating in order to prevent the transmission apparatus 2 from tilt or rollover. In other words, the auxiliary wheel 22 replaces the neighboring main wheel 21 when it is abnormal for earning the main body 20 and sliding on the guide rail 1. In the present embodiment, the predetermined height ranges from 5 mm to 15 mm such as 10 mm, etc. In another embodiment, the predetermined height can be flexible disposed based on the requirement, and the present invention does not limit it.
Obviously, the fitting method between the auxiliary wheel 22 and the guide rail 1 can also be flexible disposed. The present invention does not limit it. For instance, the auxiliary wheel 22 may have the same or similar structure with the main wheel 21. In addition, the material of the main wheel 21 and the auxiliary wheel 22 can also be flexible according to the specific requirement.
In the present embodiment, when the main wheel 21 rises or falls because of the abnormality, the auxiliary wheel 22 and the guide rail abut together to replace the main wheel 21 for supporting the transmission apparatus 2. It is easily understood, the present embodiment is to make the bottom of the auxiliary wheel 22 higher than the bottom of the main wheel 21. And its specific setting way can be flexibly selected. For example, the auxiliary wheel 22 is selected to have a smaller size than the main wheel 21, or to lift the center of the auxiliary wheel 22, etc. The present invention will not limit it.
It should be particular noted that the auxiliary wheel 22 does not necessarily arrange with the main wheel 21 in the same row because they can slide on different guide rails. For example, in another embodiments, they can be disposed on two parallel guide rails that are an outer guide rail and an inner guide rail, and the wheel is moving on the outer guide rail, whereas the auxiliary wheel is moving on the corresponding inner guide rail (and vice versa), and the auxiliary wheel and the inner guide rail is separated by a predetermined distance.
The benefit of the present embodiment is that the manufacturing cost of the additional guide rails can be omitted, but it should be understood that this does not constitute a limitation of the deposition of the guide rail 1 in the present invention.
In order to protection, the outer periphery of the main wheel 21 may be disposed with a rubber pad 210; the outer periphery of the auxiliary wheel 22 may also be disposed with a rubber pad 220. Since the disposition of the rubber pads is easily to be understood by the person skilled in the art, it does not repeat here. It should be understood that the shape, the structure and the other characteristics of the rubber pads in the present invention are not limited. Similarly, in other embodiments, it can also use a plastic pad, a silicone pad, or other elastic pads.
In the present embodiment, the number of the main wheels 21 may be four, and they are respectively disposed at the four corners of the bottom of the main body 20. Correspondingly, the number of the auxiliary wheels 22 may also be four, and each of the auxiliary wheels 22 is disposed correspondingly to a location adjacent to one of the main wheels 21.
It is worth mention that the specific number of the main wheels 21 and the auxiliary wheels 22 of the present invention are not limited. In another embodiment, the related technical person can dispose other number of the wheels with the three, six, or eight, wheels or auxiliary wheels according to requirement as long as it is capable of supporting the transmission apparatus 2, and at least one of the auxiliary wheels corresponds to each of the wheels.
In addition to the main body 20, the main wheel 21 and the auxiliary wheel 22, the transmission apparatus 2 further includes an alarm unit 24 and an sensor 23 disposed at the connection location between the main wheel 21 and the bottom of the main body 20. The sensor 23 is for detecting whether the main wheel 21 is abnormal. The alarm unit 24 is connected to the sensor 23 and is for generating an alarm when the sensor 23 detects that the main wheel 21 is abnormal.
With reference to
In the present embodiment, the sensor 23 may be a pressure sensor. In general, when the sensor 23 detects that the pressure is changed suddenly or over deviation from its normal value, it determines that the operation of the system occurring abnormality.
When the number of the main wheels 21 is four, the number of the sensors 23 also can be four, and the four sensors 23 are corresponding to the four main wheels 21 one by one. In other words, each of the main wheels 21 has one of the sensors 23 corresponding to it in order to perform a real-time monitoring for the exerted pressure on each of the main wheels 21. When any of the main wheels 21 is abnormal the corresponding sensor 23 can timely detect.
Of course, in another embodiment, the specific location and the number of the sensors 23 can be disposed flexibly. For example, in addition to disposing the sensor 23 above the main wheel 21, it can also dispose the sensor 23 at the connection location between the auxiliary wheel 22 and the bottom of the main body 20 in order to comprehensively monitor the operation data of the transmission apparatus 2.
The specific type of the sensor 23 can also be selected flexibly. In another embodiment, it may also be other types of sensors. For example, it can dispose a distance sensor at the bottom of the main body 20 for detecting the distance between the main body 20 and the guide rail 1 or the distance between the main body 20 and the ground. Obviously, when the detected distance is changed, the root cause is that the main wheel 21 has the abnormality so that the change of the distance can inform the person that the operation of the apparatus is abnormal That is, the distance sensor at this time is actually for detecting whether the main wheel 21 is abnormal and at this time, the distance sensor and the aforementioned pressure sensor are all disposed at the bottom of the main body 20.
The alarm unit 24 cooperates with the sensor 23. Specifically, the alarm unit 24 generates an alarm when the sensor 23 detects that the main wheel 21 is abnormal. It is easily understood that the alarm unit 24 may be disposed at an arbitrary position of the transmission apparatus 2 through a specific way to connect with the sensor 23. The cooperation method between the alarm unit 24 and the sensor 23 is belong to the contents can be easily understood by the person skilled in the art. The present invention will not repeat here.
It is worth mention that the alarm unit 24 may be a mechanical alarm device or an electronic alarm device. The way for generating a specific alarm may be the form of voice, light, or sound, etc., and the present invention does not limit the specific characteristics of the alarm unit 24.
It should be pointed out that in the present embodiment, the transmission apparatus 2 may be an automatic crane, and in other embodiments, tire transmission apparatus 2 may be other mechanical devices. The present invention does not limit it.
For a better understanding, the following content assumes that one of the main wheels 21 falls off and the sensor 23 is a pressure sensor for describing the operating process of the transmission apparatus 2.
First, when one of the main wheels 21 falls off, the corresponding sensor 23 detects that the exerted pressure on the wheel 21 is changed. At the same time, the auxiliary wheel 22 corresponding to the main wheel 21 abuts to the guide rail 1 to support the transmission apparatus 2 for continuing operation;
Secondly, when the abnormality is detected in the sensor 23/after, the alarm unit 24 generates an alarm to inform the relevant staff;
Finally, after receiving the alarm by the relevant staffs (for example, hearing the alarm bell), they timely arrive on the scene to understand the situation and decide the next specific step which should be taken.
The transmission apparatus of the LCD panel of the present invention achieve the real-time monitoring for the operation of the main wheel 21 by disposing the sensor 23 to detect the abnormality. When the main wheel 21 or the transmission apparatus 2 is abnormal, the alarm unit 24 generates the alarm and informs the relevant staffs to prevent the further loss. Meanwhile, when abnormal conditions occur, such as the tailing of the main wheel 21, the auxiliary wheel 22 may support the transmission apparatus 2 to continue operating. Therefore, it effectively prevents the transmission apparatus 2 from tilt or rollover due to the abnormality of the main wheel 21.
Furthermore, in the transmission system, the guide rail 1 is formed integrally or smooth transition connection such that the impact force of the guide rail 1 to the main wheel 21 or the auxiliary wheel 22 can be reduced. Thereby, it greatly improves the life of the main wheel 21 or the auxiliary wheel 22 and reduces maintenance and replacement costs.
