In the above embodiment, the rotation unit 900 of the auxiliary mechanism is disclosed, because the vertical direction of the wrist mounting template may not be flush with the wrist upright 200 due to some reasons during the process of docking with the wrist upright 200, so that the rotation unit 900 may be provided to perform fine rotation adjustment on the wrist mounting template, so that the wrist mounting template is kept vertical in the vertical direction. I.e., flush with the wrist upright 200, thereby ensuring an accurate interface between the wrist mounting template and the wrist upright 200.
In some embodiments, specifically, the rotating unit 900 is a rotating platform fixed at an end of the turning part 601 far from the connecting unit 400.
In the above embodiment, the rotating platform is a mature prior art, and can effectively achieve the fine tuning rotating effect.
Fourthly, the longitudinal sliding unit 700 and the connection with the rotating unit 900, the transverse sliding unit 800 and the connection with the longitudinal sliding unit 700:
referring to fig. 5, in some embodiments, the auxiliary mechanism further includes a longitudinal sliding unit 700, and the longitudinal sliding unit 700 is configured to drive the template fixing portion 808 to move longitudinally along the existing line.
In the above embodiment, the longitudinal sliding unit 700 is provided, because during specific construction, a certain error may exist between the parking position of the rail flatbed 100 and the design position, so that a certain error may occur between the parking position and the cantilever upright 200 in the longitudinal direction of the existing line, and the template fixing portion 808 is further away from the upright, and by providing the longitudinal sliding unit 700, the longitudinal movement of the template fixing portion 808 may be realized, so as to compensate the error, and further, the assembly between the cantilever installation template and the cantilever upright 200 is facilitated.
Referring to fig. 5, in some embodiments, the auxiliary mechanism further includes a transverse sliding unit 800, and the transverse sliding unit 800 is configured to drive the template fixing portion 808 to move along the transverse direction of the existing line.
In the above embodiment, the lateral sliding unit 800 is provided, because there is a safety distance between the robot arm 300 and the cantilever column 200 during the movement, the safety distance may cause a certain distance between the cantilever installation template and the cantilever column 200 in the lateral direction of the existing line, and the lateral movement of the template fixing part 808 may be realized by providing the lateral sliding unit 800, so as to compensate the above distance, and further facilitate the assembly between the cantilever and the cantilever column 200.
It should be emphasized that, during specific construction, when a large error exists between the parking position of the track flat car 100 and the design position, the error cannot be compensated only by the longitudinal sliding unit 700, and at this time, the rotation function of the mechanical arm 300 itself needs to be exerted, that is, the mechanical arm 300 itself rotates to drive the mechanical arm head to rotate towards the wrist upright 200, so that the template fixing portion 808 and the wrist mounting template are close to the wrist upright 200.
However, the above method has a big problem: that is, at this time, a side surface of the cantilever installation template close to the cantilever upright post 200 and a plane of the cantilever upright post 200 may be greatly inclined, and due to the rotation of the mechanical arm 300, the cantilever installation template may be farther from the cantilever upright post 200 in the transverse direction of the existing line, at this time, the horizontal turning unit 600 may be used again, and the horizontal turning of the cantilever installation template may be implemented by the horizontal turning unit 600, the specific steps have been mentioned above and will not be repeated for a while, so that a side surface of the cantilever installation template close to the cantilever upright post 200 and a plane of the cantilever upright post 200 may be implemented, and at this time, the transverse sliding unit 800 may be combined to implement the butt joint between the cantilever installation template and the cantilever upright post 200, so it is not difficult to find that the problem that the butt joint between the cantilever installation template and the cantilever upright post 200 may not be implemented due to a large parking error of the track flat car 100 may be effectively solved by the cooperation of the horizontal, and the provision of both the horizontal flipping unit 600 and the lateral sliding unit 800 serves to solve problems other than the fundamental problems thereof.
If the horizontal overturning unit 600 is not arranged, the cantilever installation template can be close to the cantilever upright post 200 only through the matching of the mechanical arm 300 and the longitudinal sliding unit 700, but the problem of the side inclination of the cantilever installation template cannot be solved.
It should be emphasized that, in the above implementation process, the sinking of the arm head is further aggravated due to the further extension of the lateral sliding unit 800 and the forward movement of the center of gravity, and at this time, the up-and-down turning function of the connection unit 400 is assisted, so that the problem of the sinking of the arm head caused by the fact that the horizontal turning unit 600 and the lateral sliding unit 800 must be used due to a large parking error of the rail flatbed 100 can be effectively solved, and the effect also realizes the further utilization of the up-and-down turning function.
It should be further emphasized that, in the above implementation process, the longitudinal sliding unit 700 is further used in combination, so that the distance between the cantilever installation template and the cantilever upright 200 in the longitudinal direction of the existing line can be reduced within a certain range, the rotation angle of the mechanical arm 300 is reduced, and the telescopic length of the transverse sliding unit 800 can be further shortened, thereby alleviating the sinking problem of the mechanical arm head.
To sum up, it is not difficult to discover that through setting up horizontal upset unit 600, the unit 800 that transversely slides, the unit 700 that vertically slides and the linkage unit 400 that can overturn from top to bottom, can be effectively comprehensive solve track flatbed 100 because of berthing the great problem that causes the unable and wrist arm stand 200 of butt joint between the cantilever erection template of great error, and mutually support between each unit, play the application to overall structure is most reasonable, overall design scientific and reasonable.
