Pneumatic monorail crane

Abstract

The invention discloses a pneumatic monorail crane and belongs to underground coal mine auxiliary transport equipment. The pneumatic monorail crane comprises a rail, a bearing trolley, a driving device, a brake device and walking wheels, wherein the driving device comprises a pneumatic motor and a reduction gearbox and further comprises a pneumatic controller and a pressure regulating valve; the brake device is connected with the reduction gearbox; the pneumatic controller is fixed at the outer part of the whole machine and connected with the pneumatic motor through a pipeline; the pressure regulating valve is fixed in a pipeline system and between the pneumatic motor and the pneumatic controller; gas is supplied to the pneumatic motor by the pneumatic controller through the pressure regulating valve, and meanwhile, the running speed of the monorail crane is regulated through regulating the gas supply quantity. The brake device of the pneumatic monorail crane is connected with the main machine, the structure is compact, the operation is convenient, the speed of the crane in braking and starting processes can be regulated, low-speed starting and braking are realized, and meanwhile, the work noise can be lowered.

Description

technical field [0001] The invention relates to the field of coal mine auxiliary transportation equipment, in particular to a pneumatic monorail crane. Background technique [0002] Monorail crane is a kind of auxiliary transportation equipment with strong mobility, fast running speed, large load capacity, safe and reliable driving on the suspension monorail system. The transportation of supported materials and equipment can also be used for underground transitions and other places that require short-distance transportation. A monorail crane can realize continuous and direct transportation without reloading in roadways with variable slopes, multi-branches, and multi-branch lines, and is not affected by deformation of the roadway floor, water accumulation or material accumulation, and has been more and more widely used in coal mines. [0003] Pneumatic monorail crane is a common equipment in existing monorail cranes in coal mines. Pneumatic monorail crane is a device that u...

AI Technical Summary

Problems solved by technology

Existing pneumatic monorail cranes are mainly composed of rails, air motors, deceleration mechanisms, brake trolleys, friction wheels and bearing trolleys. The braking part is separated from the main part of the crane, and the structure is scattered and not centralized, and the air pressure cannot be adjusted. , so that the speed cannot be adjusted during braking and starting

In addition, the carrying capacity of the existing pneumatic monorail cranes is low, which cannot meet the carrying capacity set by the technical requirements, and the noise of the cranes is relatively loud when they are working, causing noise pollution to the working environment and affecting the physical and mental health of the operators.
