The present invention relates to a three-dimensional parking garage.
Owing to economic development, urban population and the number of vehicles grow year by year and the problem of parking in the urban area needs to be solved. The traditional single-floor and plane parking garages occupy a large number of precious land resources and cannot meet needs indefinitely.
The modern advanced automatic three-dimensional parking garage is a three-dimensional parking garage with multiple planes. The three-dimensional parking garage has the single-floor plane parking garage as the core and changes the spatial positions of the parking lots by microcomputer so as to realize the transfer from space to plane of the parking lot, thus achieving the function of parking in multi-floor plane. However, the beam-column members of the existing three-dimensional parking garage, such as various kinds of bearing bridging beams of the frame, connecting column and so on, adopt standard sections. The standard sections purchased in the market directly are often in simple structure and generally also need to have the through-holes or grooves opened so as to fit to other equipment and connecting structures. Therefore, the standard sections purchased from the market can not be used as the goods shelf or the bridging beam or column of the garage frame, while the processes like cutting and drilling in the standard sections need manual lineation and lofting, which not only leads to the low processing speed, low efficiency, great difficulties in ensuring the geometric accuracy and geometric tolerance of the holes and grooves but also results in the waste of the raw materials and low material utilization.
In addition, the vehicle carrier of the existing three-dimensional parking garages is mostly in frame structure which generally comprises a left side beam, a right side beam and a bridging beam disposed between the left beam and the right beam. The integrated vehicle plate is arranged between the left side beam and the right side beam, and the vehicles park on the vehicle plates. The disadvantage of vehicle plate is that the vehicle plate is of a great span length. To guarantee the carrying capacity, the vehicle plate can not be too thin and generally be made of 2 mm steel plate, thus the materials needed for the vehicle plate shall be relatively thick with a lot of materials consumed and high cost. Moreover, no guiding beams are installed in existing vehicle plates in general. When driving into the parking lots of the three-dimensional parking garage, it is very easy for the vehicles to deviate from the middle straight-line direction, which leads to the condition of inclined parking on the vehicle carrier and brings inconvenience when the vehicles drives away from the vehicle carrier.

A accessorial frame 9 which is disposed along the length of the bottom frame 8 and located in a center of the bottom frame 8, and fixed with the bottom frame 8 by the bolts is in a frame structure, the accessorial frame 9 further comprises two guiding beams 91, a front cross rail 92, and a rear cross rail 93, the front cross rail 92 and the rear cross rail 93 connecting two guiding beams 91.
Furthermore, a plurality of intermediate cross rails 94 are placed between the front cross rail 92 and the rear cross rail 93, connecting the two guiding beams 91, and both two guiding beams 21 are respectively provided with a recess 911 with a size matching the width of the middle bridging beam 84 located at the corresponding place of the middle bridging beam 84, the ends the middle bridging beam 84 are respectively positioned in the recesses 911, so that the bottom of the accessorial frame 9 is able to be flush with the bottom of the bottom frame 1.
A first vehicle plate 31, with a left side and right side, is placed between the accessorial frame 9 and the left beam 81, and a second vehicle plate 32, with a left side and a right side, is placed between the accessorial frame 9 and the right beam 82, each of the left beam and the right beam has a first inner wall and a second inner wall, the left side of the first vehicle plate 31 is perpendicularly mounted to the first inner wall of the left beam 81, the right side of the first vehicle plate 31 is mounted to the accessorial frame 9, while, the right side of the second vehicle plate 32 is perpendicularly mounted to the second inner wall of the right beam 82, the left side of the second vehicle plate 32 is mounted to the accessorial frame 9. Thus, the vehicle plate for parking the vehicles is divided into two parts respectively disposed transversally between the beam and the guiding beam 91 which is relative to the said beam. After the vehicle enters into the vehicle carrier, the tires of the vehicle respectively park on the vehicle plates on both sides of the accessorial frame 9. Because the span length of the vehicle plate is smaller, the thin materials can be used in the same carrying capacity, and the 1.6 mm thick steel can be used directing. So the weight of the vehicle carrier can be abated evidently (compared with the prior art, it can be abated about a quarter), and the cost of the production is significantly lower too.
To prevent the engine oil or dust of the vehicles which park in the vehicle carrier dripping to the inside of the vehicle carrier from the interspace of the accessorial frame 9, a grease baffle 4 is provided on the accessorial frame 9, and the grease baffle 4 has a plurality of grooves 41. The trapeziform groove 41 which can be a whole or scrabbled up from some pieces has the function of accumulating and conducting, and the grease baffle 4 can be cleaned conveniently with the trapeziform groove 41.
To prevent the surface of the tires is damaged by the deams of the bottom frame 8 or the accessorial frame 9 when the vehicles enter into or exit from the vehicle carrier, the front cross rail 92 and two guiding beams 91 forming two joint corners, each joint corner being formed with a first inclined cutting surface and each inclined cutting surface 51 is covered with an inner protecting seal head 52. While one second inclined cutting surface is formed at a front end of each of the left beam 81 and the right beam 82, each second inclined cutting surface is covered with an outer protecting seal head 53.
The structure of the vehicle carrier in accordance with an embodiment of the present invention can be not only applied in the cross sliding vehicle carrier, but also applied in the lift vehicle carrier. Particularly, because of the uneven load and the acceleration of gravity in the lift process of the lift vehicle carrier, the left beam 81 and the right beam 82 will be distorted, while the distortion of the beam will make the body of the vehicle carrier be distorted wholly. To avoid the vehicle carrier being distorted, each of the left beam 81 and right beam 82 of the bottom frame 8 is provided with a first tension mechanism. The first tension mechanism can provide the vehicle carrier with a pretightening force which is just balanced against the pressure that the vehicle carrier gets, thus preventing the distortion of the vehicle carrier.
The first tension mechanism comprises a drawbar 61 along the length of the bottom frame 8, two first supporting pieces 63 mounted on either the left beam 81 or the right beam 82, (the supporting pieces fix on the left beam 81 or the right beam 82 by jointing or bolt) and two tension nuts 62 for positioning the supporting pieces; the drawbar 61 has two ends supported respectively by two supporting pieces 63. Furthermore, each end of each drawbar 61 has thread and is respectively coupled with a tension nut 62 limited in the corresponding supporting pieces 63. Adjust the tension nuts 62 to let the drawbars 61 haunch-up when both ends of the drawbars 61 are pressed and press the supporting pieces 63, thereby making the beam haunch-up. When the vehicles enter into the vehicle carrier, the distortion of the vehicle carrier under the downward stress is just balanced against the upward haunch-up distortion of the beams, thus preventing the distortion of the vehicle carrier.
Taking into account that the front side of the vehicle carrier is distorted badly when the vehicles on the lift vehicle carrier enter into or exit from the vehicle carrier, and to avoid the part distortion of the vehicle carrier and improve the rigidity of the vehicle carrier, a second tension mechanism mounted on the bottom frame 8 is located in the rectangle frame structure which contains the middle bridging beam 84, the front bridging beam 83, the left beam 81 and the right beam 82. The second tension mechanism comprises a first diagonal drawbar 71 secured by two adjusting nuts and mounted between the front bridging beam 83 and the left beam 81 and a second diagonal drawbar 72 secured by two adjusting nuts and mounted between the front bridging beam 83 and the right beam 82. By adjusting the tightness of the adjusting nuts, the pull between the first diagonal drawbar 71 and the second diagonal drawbar 72 can be adjusted, so the beams of the vehicle carrier can produce a certain forced distortion which can be balanced against the distortion of the stressed vehicle carrier, to ensure the local rigidity and the accuracy of form and position, keep the vehicles in a balanced condition during the lifting process, and improve the safety of the operation and the service life of the vehicle carrier.
In the present embodiment, the accessorial frame 9 is disposed in the bottom frame 8, and the vehicle plates are laid between the accessorial frame 9 and the beam. The whole structure which contains the left beam 81, the right beam 82, the assistant beam 9, the bottom beam 8 and the grease baffle 4 not only reduces the span length of the vehicle plate, saves the materials, and reduces the weight and the cost, but also significantly improves the wholly rigidity of the vehicle carrier. Furthermore, the assistant beam 9 itself can also play a role in guiding, so when the vehicles enter into the vehicle carrier, both sides tires of the vehicles go along the guiding beams 91 of the assistant beam 9 to ensure the moving direction of the vehicles, and avoid the vehicles shifting on the parking direction, as well as make the movement convenient when the vehicles exit from the vehicle carrier again, thus make the parking easier and provincial.
