Drawings
The following brief description of the drawings and reference numerals in the drawings forms a part of this specification:
FIG. 1 is a schematic view of the locking device of the present invention.
Fig. 2 is a schematic view of the guide wheel lock of the present invention.
In the figure:
1. the device comprises universal wheels, an underframe 2, a hydraulic jack 3, a guide frame 4, a lifting plate 5, a sliding rail adjusting structure 6, a locking tray 7, a limiting baffle 701 and a bogie guide wheel 8.
Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the APM vehicle bogie locking device comprises an underframe 2, a hydraulic jack 3, a lifting plate 5, a horizontal movement adjusting structure and a locking tray 7 for locking a bogie against a bogie guide wheel; the hydraulic jack is arranged on the bottom frame, the lifting plate is arranged at the top of the hydraulic jack, and the locking tray is arranged on the lifting plate through the horizontal movement adjusting structure.
The underframe 2 is of a frame structure, a universal wheel 1 is arranged at each corner of the frame structure, and the lower end of a hydraulic jack is fixed at the center of the frame structure; the universal wheels are used for moving, the movement is flexible and convenient, and the alignment of the locking tray and the guide wheels of the bogie is convenient.
The below of lifter plate is equipped with leading truck 4, and the lower extreme of leading truck is equipped with and is used for the guide hole of cover on hydraulic jack outer fringe, and the leading truck is frame construction, supports to go up and down reliable and stable.
The hydraulic jack 3 is a pedal hydraulic jack, and the lifting operation is simple and convenient; the horizontal movement adjusting structure is a hand-operated sliding rail adjusting structure 6, a screw rod sliding block structure is preferably selected, a handle is arranged at the end of a screw rod, the sliding block is driven to move on the sliding rail through the rotation of the handle, the locking tray is arranged on the sliding block, and the locking tray moves leftwards and rightwards and is quickly aligned to the approaching guide wheel.
The locking tray 7 is of a flat plate structure, and an avoidance through hole is formed in the central position, corresponding to the guide wheel below the bogie, of the locking tray; the below of bogie is equipped with two bogie leading wheels 8, and the leading wheel level sets up, has the clearance between two leading wheels, dodges the pivot tip of leading wheel through dodging the through-hole on the tray.
