Embodiment Construction

[0033] The specific embodiments of the present invention will be further described with reference to the accompanying drawings.

[0034] The tail of the step-type self-moving belt conveyor for rapid excavation is mainly composed of a self-moving mechanism (frame, bracket) and a rigid frame connected by several sections with pins. The unloading device matched with it during operation can be within the range of its total length of 60m The unloading on the rigid frame realizes the continuous transportation of coal. The tail of the step-by-step self-moving belt conveyor for rapid excavation has a self-moving function, which can be followed by a hydraulic support and a self-moving mechanism when the roadway excavation equipment is moved forward, which is convenient and flexible. The invention of the tail of the step-by-step self-moving belt conveyor reduces the number of reciprocating movements of the traction equipment in the roadway, reduces the damage to the floor by the equipme...

Abstract

The invention belongs to the technical field of designing and manufacturing of driving working face devices in a coal mine and particularly relates to a stepping self-moving rubber belt conveyor tail used for fast driving. The problems existing in the moving mode of an existing driving working face belt conveyor tail are solved. The stepping self-moving rubber belt conveyor comprises a rigid frame, a roller and a rack. The rack comprises a front rack and a back rack, a beam is connected between the front rack and the back rack, a base is arranged between the front rack and the back rack, and guide rails are connected with the bottom of the base. A push moving oil cylinder is arranged on the beam, and a stand column mechanism and a four-bar mechanism are arranged at the top of the base. Roller boxes are arranged on the two sides of the front rack and the two sides of the back rack. The roller boxes are matched with the guide rails in a sliding mode, and lifting oil cylinders are connected inside the roller boxes and arranged in the vertical direction. The stepping mode is unique, and a set of device combines a hydraulic support and the belt conveyor tail to achieve stepping self moving, so that the requirement for fast moving of the device under different working conditions is met. The stepping self-moving rubber belt conveyor tail is simple in structure, convenient to install and flexible in operation.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of equipment for underground excavation working face in coal mines, in particular to a stepping type self-moving belt conveyor tail for rapid excavation. Background technique [0002] At present, there are three general moving methods for the tail of the belt conveyor in the underground tunneling face: the pulling of the roadheader, the pulling of the winch, and the self-moving of the self-moving tail. The reciprocating driving of the roadheader will cause great damage to the bottom plate, and it is always easy to pull the tail of the belt conveyor away. The winch traction method is simple and convenient, but when the wire rope is pulled and moved, it affects the normal operation of the surrounding equipment, and there is a hidden danger of safety accidents caused by wire rope breakage. The self-moving tail of the belt conveyor works in cooperation with the loader, relies on the lo...
