Abstract

The present invention is applicable to the technical field of mining mechanical devices, and provides a mine-used endless rope tractor, comprising a car body and a first braking mechanism for braking when the car body travels along the first direction, The first braking mechanism includes a first moving pulley rope storage assembly, a first reset member, a first braking assembly and a first retracting and releasing assembly. The mine-used endless rope tractor provided by the present invention is provided with a first frame and a first pulley for winding the traction rope, so that the first end of the traction rope is loosened for a certain preset length before triggering the first retraction and release. The assembly releases the first brake assembly to perform vehicle body braking, avoiding the problem of brake misoperation caused by short-distance overspeed, and improving the transportation efficiency of the mine-used endless rope tractor provided by the embodiment of the present invention.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, and more specifically relates to a mining endless rope tractor. Background technique [0002] The mine-used endless rope clamp rail tractor has been widely used in the conditions of up and down hills in coal mining areas and along the trough of the working face, especially for long-distance, large-inclination, multi-slope, and large-tonnage rail transportation, and its superiority is more obvious. But the brake safety problem of the tractor is particularly prominent. [0003] At present, the braking structures of existing tractors mainly include hydraulic braking structures and mechanical plug-in braking structures, etc. Although the existing braking structures can perform emergency braking on sports cars caused by loose and Short-distance speeding may occur when the car is going downhill. This short-distance speeding phenomenon is generally not risky, but the existing braking structure...
