Wall-mounted transmission device of crane

Abstract

The invention discloses a wall-mounted transmission device of a crane. The wall-mounted transmission device of the crane comprises a bearing rod, a sliding block guide rail, supports and a sliding block, wherein fixing plates are fixedly welded to the bottoms of the supports, and a bearing plate is fixedly welded to the tops of the supports; the sliding block guide rail is fixedly arranged at thecenter of the side face, far away from the supports, of the bearing plate through screws; the sliding block is arranged outside the sliding block guide rail in a sliding mode, a bearing pulley is fixedly arranged in the sliding block, and the sliding block is in sliding connection with the sliding block guide rail through the bearing pulley; and the outer wall of the sliding block is fixedly provided with a bearing rod fixing plate through screws, the bearing rod is fixedly welded to the side face, far away from the sliding block, of the bearing rod fixing plate, and fixed pulleys are fixedlyarranged in the two ends of the bearing rod respectively. According to the wall-mounted transmission device of the crane, the fixing plates welded to the bottoms of the supports can be used for directly and fixedly installing the device on a wall surface or other equipment, so that the occupied operating space is relatively small; and the wall-mounted transmission device of the crane is suitable for the lifting work with small work amount, and is convenient to install and transport.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a transmission device for a wall-mounted crane. Background technique [0002] The bridge crane is a lifting device that is horizontally placed over the workshop, warehouse and stockyard for material lifting. Because its two ends are located on tall concrete pillars or metal supports, it is shaped like a bridge. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated sides on both sides, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is a kind of hoisting machinery with the widest range and the largest number. [0003] Some working characteristics of lifting equipment are intermittent movements, that is, in a working cycle, the corresponding mechanisms for retrieving, moving, unloading and other actions work alternately. The development and use of cranes in the mar...

AI Technical Summary

Problems solved by technology

[0005] 1. Traditional cranes are generally large in size, and are generally difficult to use when performing small hoisting work, and traditional cranes are very inconvenient to transfer and install, and need to occupy a large operating space, which is not suitable for small hoisting projects

[0006] 2. Traditional small lifting equipment does not have a safety switch, and manual observation is required to control the lifting height. When the lifting equipment lifts the object to the bottom of the equipment, if the lifting equipment is not stopped manually in time, because there is no safety switch, the motor will continue to generate power to pull Ropes, so the lifting motor will be overloaded and burned, and even the equipment will be damaged, which poses a safety hazard
