Slag removal device for full-section hard rock heading machine

Abstract

The invention discloses a slag removal device for a full-section hard rock heading machine. The slag removal device comprises a slag removal body, motors, speed reducers, motor connecting seats and tight supporting seats are symmetrically arranged on the two sides of the slag removal body, the motors are connected with the speed reducers through bolts, the speed reducers are connected with the tight supporting seats through the motor connecting seats, the tight supporting seats are slidably mounted on the slag removal body, a driving wheel device is arranged on the inner side of the slag removal body, accumulated slag in the axial direction and the radial direction of a tunnel can be removed through a mechanical automation means, and the operation efficiency of the machine is improved. A mechanical structure and hydraulic control cooperate to tension a chain wheel, so that the production cost of equipment is reduced while the efficiency is ensured; a slag removal bucket movement mechanism rotates in the slag removal body, the slag removal device is compact in structure, and the safety and reliability of the mechanism during operation are ensured; and the application range is wide, and the slag removal device can be applied to slag removal operation of multi-diameter and multi-type full-section hard rock heading machines by adjusting the motion trail of a roller chain.

Description

technical field [0001] The invention belongs to the technical field of slag cleaning devices for full-section hard rock tunneling machines, and in particular relates to a slag cleaning device for full-section hard rock tunneling machines. Background technique [0002] The full-face hard rock boring machine is a large-scale modern mechanical equipment used in tunnel construction. In the actual construction process of the full-face hard rock tunnel boring machine, there is a phenomenon of slag accumulation in the lower part of the tunnel. If it is not cleaned up in time, it will affect the advancement of the trailer in the rear section, thereby affecting the operating efficiency of the whole machine. At present, there are several conventional cleaning methods for the slag in the tunnel: one is manual operation, but there are problems such as low efficiency, high labor cost, and operation safety; the other is to use hydraulic mechanical arms to clean the accumulated slag , thi...

In the actual construction process of the full-face hard rock roadheader, there is a phenomenon of slag accumulation in the lower part of the tunnel. If it is not cleaned up in time, it will affect the advancement of the rear trailer, thereby affecting the operating efficiency of the whole machine

At present, there are several conventional cleaning methods for the slag in the tunnel: one is manual operation, but there are problems such as low efficiency, high labor cost, and operation safety; the other is to use hydraulic mechanical arms to clean the accumulated slag , this method can realize automatic control and reduce labor costs, but it increases equipment production costs and later equipment maintenance costs. In addition, the mechanical arm has high requirements for installation position and space, and the structure is not compact, so it cannot make full use of the limited space.
