Problems solved by technology

[0002] With the development of automation, the maintenance elevators all adopt pneumatic rail alignment mechanism. Although the pneumatic connection saves manpower, it requires high machining accuracy and installation error. If the deviation is large, it will be difficult to align the rail and the mechanism will be easily damaged.
After the trolley enters the maintenance rail, there is no automatic limit mechanism. The trolley is easy to shake back and forth. If there are iron filings in the track and it is not cleaned in time, the trolley will be scratched

Embodiment Construction

[0017] The present invention will be further explained below according to the drawings.

[0018] like Figure 1-4 As shown in the figure, the rail alignment and limit device used for the maintenance of the elevator includes a carriage 1, a righting rail 2, a limit component 3, a movable rail 4, a positioning pin cylinder 5, a rail alignment mechanism 6 and a cage 9. The movable rail The track 4 is fixed on the carriage 1, the limiting assembly 3 is fixed on the movable track 4, and a rail alignment mechanism 6 is respectively provided on both sides of the carriage 1, and the rail alignment mechanism 6 includes a positioning assembly 7 and The stopper 8 , the centralizing rail 2 , the positioning pin cylinder 5 and the holder 9 are screwed on the carriage 1 respectively.

[0019] like image 3 As shown, the bottom of the limit assembly 3 is the base 31, the limit blocks 32 on both sides are fixed on the base 31 through the connecting rod 35, the pull rod 34 is connected with ...

Abstract

The present invention involves a pairing and restriction device for repairing the lift machine, which is a mechanical reprint field, including sliding, corrected orbit, limited components, activity tracks, positioning sales, rail mechanisms and maintenance racks.The orbit is fixed on the slide, and the limit component is fixed on the track track. There is a pairing mechanism on both sides of the slide.The sleeves and the kernels are carried on the slide separately.This maintenance lift does not require electrical and other equipment for rails and limited devices, saving costs, and compact structures. It does not occupy excess space. Manual operation can complete the connection between the lift and the platform and the platform limit., Simple and feasible.

Description

technical field [0001] The invention relates to a rail alignment and limit device used for maintaining elevators, and belongs to the field of mechanical transfer. Background technique [0002] With the development of automation, the maintenance lifts all adopt the pneumatic rail alignment mechanism. Although the pneumatic connection saves manpower, it requires high machining accuracy and installation error. If the deviation is large, it will be difficult to align the rail, and the mechanism is easily damaged. . After the trolley enters the maintenance track, there is no automatic limit mechanism, and the trolley is easy to shake back and forth. If the iron filings in the track are not cleaned in time, the trolley will be scratched. Since the maintenance lift is not frequently used, it is used once every six months or more. Therefore, during maintenance, you only need to slowly open the blocker to allow the trolley to enter the maintenance section, and pull the limit compone...
