Supporting frame with adjusting structure for elevator maintenance

Abstract

The invention discloses a supporting frame with an adjusting structure for elevator maintenance. The supporting frame comprises a base, wherein inserting grooves are formed in the four sides of the base correspondingly; fixing mechanisms are fixedly installed in the four inserting grooves correspondingly; a lifting mechanism is fixedly installed in the middle of the top end of the base; the lifting end of the lifting mechanism is rotationally connected with a cylinder; four fixing rods are fixedly installed on the sides of the cylinder at equal intervals; and a plurality of buffer mechanisms are fixedly installed at the top ends of the four fixing rods at equal intervals. According to the supporting frame, the lifting mechanism is installed at the top end of the installed base, a rotatingshaft is driven to rotate through rotation of a servo motor, a first bevel gear is driven to rotate through rotation of the rotating shaft, the first bevel gear is meshed with a second bevel gear, sothat two threaded rods are driven to rotate synchronously, a limiting strip is driven to ascend and descend through rotation of the two threaded rods, a circular sleeve column is driven to ascend anddescend through ascending and descending of the limiting strip, a bottom frame is driven to ascend and descend through ascending and descending of the circular sleeve column, and therefore an elevatorcan be conveniently maintained.

Description

technical field [0001] The invention relates to a support frame, in particular to a support frame with an adjustment structure for elevator maintenance, and belongs to the technical field of elevators. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Stationary lifting equipment serving specified floors, vertical elevators have a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. [0003] According to the patent number "CN20...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a support frame with an adjustment structure for elevator maintenance, to solve the problem that the angle and height of the elevator car are not easy to adjust during the inspection and maintenance process of the above-mentioned background technology, and it is generally necessary to artificially surround the elevator car. Maintenance is time-consuming and affects the efficiency of elevator maintenance
