The present application relates to the technical field of engineering mechanical device installation, in particular to a calculation method and an installation mechanism for compressor unit single meter alignment pad iron adjustment.
Compressor units, high-pressure pumps, and generator units are often used in fields such as chemical engineering and electric power. In many projects, a single meter is usually used for unit centering alignment. By continuously adjusting a thin pad iron on a foundation support to finally achieve the error range required by alignment errors, the unit is gradually adjusted. In this way, the speed is very slow, the efficiency is also very slow, and the construction period is very long.
A purpose of the present application is to provide a calculation method and an installation mechanism for compressor unit single meter alignment pad iron adjustment, as to solve the problem of using the single meter for unit centering alignment provided in the background. By continuously adjusting the thin pad iron on the foundation support by the alignment errors, the unit is gradually adjusted. In this way, the speed is very slow, and the efficiency is also very slow.
In order to achieve the above purpose, the present application provides the following technical schemes: an installation mechanism for compressor unit single meter alignment pad iron adjustment, including: a bracket and a connecting piece installed on the bracket, and the installation mechanism further includes: an installation piece arranged on an end portion of the bracket; the installation piece is provided with a fixture for fixing a dial gauge; and the bracket is provided with an installation box, the installation box is internally and rotatably provided with a rolling rod, the rolling rod is winded with a connecting rope, one end, away from the rolling rod, of the connecting rope is provided with a fixing piece, the installation box is rotatably provided with a cam, one end of the rolling rod extends to an outer side of the installation box and is connected with the cam, the cam is provided with a groove, the installation box is provided with a limiting piece, one side, towards the cam, of the limiting piece is provided with an open slot, and the open slot is internally provided with a convex block for inserting into the groove.
As a preferred scheme, the open slot is internally provided with a touch switch, and the cam is provided with an indicator light electrically connected with the touch switch.
As a preferred scheme, the connecting rope is provided with an expansion rod, one end, away from the connecting rope, of the expansion rod is connected with the fixing piece, and the connecting rope is provided with a fixing mechanism for fixing the expansion rod.
As a preferred scheme, the fixture is provided with a first lens and a second lens.
As a preferred scheme, the bracket includes a support rod and a movable rod; and an end portion of the support rod is provided with an installation hole, the movable rod is slidably inserted into the installation hole, and the support rod is provided with a bolt for fixing the movable rod.
As a preferred scheme, the connecting piece includes two groups of installation blocks; and the two groups of the installation blocks are mutually clamped, and the bracket is thread-connected with a screw rod connected with one group of the installation blocks.
As a preferred scheme, a calculation method for compressor unit single meter alignment pad iron adjustment uses the installation mechanism for compressor unit single meter alignment pad iron adjustment, and the calculation method specifically includes the following steps.
As a preferred scheme, the calculation formula in S3 is:
Herein, Hfront is a front anchor bolt of the adjustment axis, Hrear is a rear anchor bolt of the adjustment axis, Lfront is a distance from an end face of the adjustment axis to a center of the front anchor bolt, Lrear is a distance from the end face of the adjustment axis to a center of the rear anchor bolt, and S is a distance between the two axes, and is a set value.
Compared with existing technologies, the beneficial effects of the present application are that: in the present application, a traditional method and mode of adjusting a pad iron after single meter alignment is changed. After the error is measured, it is directly substituted into the calculation formula of the present application to calculate the pad iron thickness (increased or decreased) to be adjusted, and it may be adjusted in place, the time of repeated measurement and adjustment may be saved, the time is greatly saved and the efficiency is improved, thus a large amount of cost investment is saved.
Technical schemes in embodiments of the present application are clearly and completely described below in combination with drawings in the embodiments of the present application. Apparently, the embodiments described are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor shall fall within the scope of protection of the present application.

X=(a3−a1+b3−b1)/2
After a value of X is obtained, values of Y, Z, and Hfront may be obtained according to the principle of similar triangles.
Therefore, the following conclusion may be obtained:
Similarly, it may be concluded that:
So Hfront+(b3−b1)/2=Y (Y is already calculated above,
Similarly, it may be concluded that:
After calculation, results are obtained, if Hfront<0, the calculation result is directly added to the pad iron, and if Hfront<0, the pad iron thickness is subtracted from the calculation result. The same way is performed for Hrear, but the pad iron should be adjusted simultaneously after Hfront and Hrear are calculated together, and the centering repeated measurement (the reference axis and the adjustment axis are rotated, and the dial gauge is used for testing) is performed again after adjustment.
Herein, Hfront is a front anchor bolt of the adjustment axis; Hrear is a rear anchor bolt of the adjustment axis; Lfront is a distance from an end face of the adjustment axis to a center of the front anchor bolt; Lrear is a distance from the end face of the adjustment axis to a center of the rear anchor bolt; S is a distance between the two axes, and is a set value; and gauge a and gauge b represent the dial gauges used for bidirectional measurement respectively.
Although the embodiments of the present application are shown and described already, it may be understood by those of ordinary skill in the art that a plurality of changes, modifications, replacements, and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is limited by the appended claims and equivalents thereof
