Problems solved by technology

[0002] Once the driving gear fails in the rack and pinion lifting equipment, the existing braking method that brakes the shaft of the transmission system to stop the driving gear from rotating may not be able to brake reliably. There is a certain distance from the floor position, and the existing method of manually operating the lifting equipment car to the leveling position through the turning device is also invalid due to the failure of the drive gear; therefore, a device that can support on-rail maintenance is required to ensure Safety

Abstract

The invention discloses an on-track maintenance supporting device for gear and rack lifting equipment. The on-track maintenance supporting device is characterized by comprising at least one independent safety braking device and at least one maintenance worktable; the at least one independent safety braking device independently realizes reliable braking fixation for the lifting equipment without dependence on a driving system of the lifting equipment and comprises a horizontal electromagnetic drive independent safety braking device; when the at least one maintenance worktable is unfolded to be in a first working state, a worker can stand in a lifting equipment car for checking or maintaining equipment closer to the outer part of the lifting equipment car through a window; when the at least one maintenance worktable is unfolded to be in a second working state, the worker can stand on a working platform for checking or maintaining equipment further from the outer part of the lifting equipment car; and the on-track maintenance supporting device realizes the beneficial effects that the effective space is saved, the working efficiency and the working quality are improved, and the safety protection degree is improved.

Description

technical field [0001] The invention relates to the field of lifting equipment maintenance devices, in particular to an on-rail maintenance support device for rack and pinion lifting equipment. Background technique [0002] Once the driving gear fails in the rack and pinion lifting equipment, the existing braking method that brakes the shaft of the transmission system to stop the driving gear from rotating may not be able to brake reliably. There is a certain distance from the floor position, and the existing method of manually operating the lifting equipment car to the leveling position through the turning device is also invalid due to the failure of the drive gear; therefore, a device that can support on-rail maintenance is required to ensure Safety. Contents of the invention [0003] The purpose of the present invention is to provide a method that can support various situations, support the maintenance of the moving parts of the rack and pinion lifting equipment, such ...
