Rapid excavation and stepping self-moving belt conveyor tail support device

Abstract

The invention belongs to the technical field of driving machine rubber belt conveyor tail moving and particularly relates to a fast driving stepping self-moving rubber belt conveyor tail supporting device. The problems existing in the moving mode of an existing rubber belt conveyor tail are solved. The supporting device comprises a base, a hydraulic support is welded to the base and comprises a power cylinder stand column on the front portion, a support top beam is arranged at the top of the stand column, the rear end of the support top beam is hinged to the upper end of a shield beam, and the support top beam is further connected with the shield beam through a balancing jack. The hydraulic support further comprises a front connecting bar and a rear connecting bar on the rear portion, a single-rod mode is adopted for the front connecting bar, the rear connecting bar, the hydraulic support base and the shield beam, and the front connecting bar, the rear connecting bar, the hydraulic support base and the shield beam form a four-bar mechanism. The problem that when a traditional rubber belt conveyor tail depends on other devices when moving forward is solved, therefore, the rubber belt conveyor tail can move freely at any time, frame-moving time is saved, the driving speed of a tunnel is increased, the advance speed of the rubber belt conveyor is increased, labor cost and driving cost of the tunnel are reduced, and the fast driving stepping self-moving rubber belt conveyor tail supporting device can be used in cooperation with various tunnel driving working faces.

Description

technical field [0001] The invention belongs to the technical field of moving the belt tail of a roadheader, and in particular relates to a fast-driving stepping self-moving belt tail support device. Background technique [0002] At present, there are generally three ways of moving the tail of the tape machine in the domestic roadway excavation equipment: pulling of the excavation equipment, winch traction, and self-moving of the tail of the tape machine. The tail of the traditional tape machine needs to be assisted by a winch or other equipment to move forward. When the operator works, the labor intensity is high and the safety is poor. When the excavation equipment is moved, due to the reciprocating mobilization of the excavation machine, when the base plate is in poor condition, it will be more destructive to the base plate, and it is easy to pull the belt conveyor to the wrong side. The workload of the operators is heavy, and a large number of people is required; the win...

AI Technical Summary

Problems solved by technology

When the excavation equipment is moved, due to the reciprocating mobilization of the excavation machine, when the base plate is in poor condition, it will be more destructive to the base plate, and it is easy to pull the belt conveyor to the wrong side. The workload of the operators is heavy, and a large number of people is required; the winch often affects the peripheral equipment. And the wire rope is easy to break; the self-moving of the tail of the tape machine is that the front part of the two push cylinders is connected to the tail of the tape machine, and the rear part is connected to the trough transfer machine, and the self-moving is realized by pushing and pulling the jack
