Belt conveyor mobile tail device with crawler

Abstract

The invention has a mobile tail device of a crawler belt conveyor and is installed on the tail of the belt conveyor, which includes: a jack, a supporting upper bearing, a rotating shaft seat, a rotating shaft, a support frame, a first motor, a second motor, a crawler, a crawler chassis frame, and a bearing The seat and the motor shaft, the two motor shafts are placed under the belt frame and perpendicular to the belt frame, the first motor and the second motor are respectively installed at both ends of the two motor shafts, and the crawler belts are respectively wound around the ends of the two motor shafts Between the two first motors and between the two second motors, a crawler chassis frame is installed between the two motor shafts, a bearing seat is installed on the crawler chassis frame, the upper bearing is installed on the bearing seat, and the upper bearing is installed on the bearing seat. The bearing is equipped with two parallel spaced rotating shaft seats, the two ends of the rotating shaft are respectively supported by the rotating shaft seats, one end of the two symmetrical support frames is respectively mounted on the rotating shaft, the other end is respectively fixed on the belt frame, and one end of the jack is respectively fixed on the supporting upper bearing. , and the other ends are respectively fixed on the outside of the two parallel steel frames of the belt frame.

Description

technical field [0001] The invention relates to mining transportation equipment, in particular to a belt conveyor mobile tail device with crawler belts. Background technique [0002] During the excavation process of the coal mine excavation face, it is necessary to transport the gangue out, and now most of the excavation faces use the belt conveyor to transport the gangue. With the advancement of the heading footage, the belt conveyor should also be extended, that is, the tail of the belt conveyor should be extended. In the past, manual handling of the mobile tail was mainly used. Now, some mine tunneling faces use hydraulic cylinders to advance the tail of the belt conveyor, so as to realize the mobile tail. Using the hydraulic cylinder propulsion method, although the tail movement of the mobile belt conveyor can be realized, the distance of each movement is small. To achieve a large distance movement, it must be repeated many times, which takes a long time and has low eff...

Problems solved by technology

Using the hydraulic cylinder propulsion method, although the tail movement of the mobile belt conveyor can be realized, the distance of each movement is small. To achieve a large distance movement, it is necessary to repeat the movement many times, which takes a long time and is inefficient. It can move in a straight line, so the use is limited
