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

Abstract

The invention relates to a rail aligning and limiting device for elevator maintaining, and belongs to the field of mechanical transshipment. The device comprises a sliding frame, a righting rail, a limiting assembly, a movable rail, a sleeve, rail aligning mechanisms and a retainer, wherein the movable rail is fixed on the sliding frame, the limiting assembly is fixed on the movable rail, each of the two sides of the sliding frame is provided with one corresponding rail aligning mechanism, the rail aligning mechanisms comprise positioning assemblies and stoppers, and the righting rail, the sleeve and the retainer are connected to the sliding frame in a screwed mode. The rail aligning and limiting device for elevator maintaining does not need electrical equipment and the like, saves cost, is compact and rational in structure, does not occupy extra space, can complete butt joint of an elevator and a platform and trolley limiting through manual operation, enables the trolley to stably fall to the ground to be convenient to maintain, and is simple and feasible.

Description

technical field [0001] The invention relates to a rail alignment and position limiting device used for maintenance of a lift, which belongs to the field of mechanical reloading. Background technique [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. Since the maintenance elevator is not used frequently, it is used once every half a year or longer, so only need to slowly open the stopper to allow the trolley to enter the maintenance section during maintenance, and pu...
