Embodiment Construction

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1-Figure 2 As shown, the auxiliary top running mechanism of the present invention is composed of an auxiliary top running part 1 and a connecting buffer device 2, the auxiliary top running part 1 is fixed on the connecting buffer device 2, and the auxiliary top running part 1 is fixedly connected to the roadheader through the connecting buffer device 2. 3 on. In the present invention, the connection buffer device 2 fixedly connects the auxiliary top running part 1 to the roadheader 3, and can make the auxiliary top running part 1 protrude from the roof attached to the roadway, and can also make the auxiliary top running part 1 retract to the roadheader 3 tops.

[0018] Through the action of connecting the buffer device 2, the auxiliary roof running mechanism of the present invention makes the auxiliary roof running mechanism press on the roadway roo...

Abstract

The invention relates to an auxiliary top traveling mechanism, in particular to an auxiliary top traveling mechanism which increases the traction of a tunneling machine and solves the problems of the insufficient traction and stability and the like of the tunneling machine during tunneling a steep tunnel. The mechanism is provided with an auxiliary top traveling part and a connection cushioning device, wherein the auxiliary top traveling part is fixed to the connection cushioning device, and the auxiliary top traveling part is fixedly connected on the tunneling machine by the connection cushioning device. When the tunneling machine works in a steep tunnel, since the traveling part can not provide sufficient traction and the tunneling machine can not work in the steep tunnel, the auxiliarytop traveling mechanism is required to provide the traction to enable the tunneling machine to complete the tunneling of the steep tunnel. When the tunneling machine is in the progress of tunneling the steep tunnel, the top traveling mechanism can be attached to the top plate of the tunnel, so that the tunneling machine can obtain the sufficient traction and the favorable stability, thereby greatly raising the tunneling efficiency and meeting the requirements for tunneling a steep tunnel by the tunneling machine.

Description

technical field [0001] The invention relates to an auxiliary top traveling mechanism, in particular to an auxiliary top traveling mechanism for increasing the traction force of a road tunnelling machine. Background technique [0002] At present, most of the roadway roadheaders in coal mines have problems such as insufficient adhesion and unsafe driving operations under the condition of large slope driving. In order to completely solve the above problems, it is necessary to transform the roadheader, and increase the auxiliary top traveling mechanism to increase the traction force and the stability and safety of the whole machine. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an auxiliary top traveling mechanism of roadway boring machine, which is a mechanism for increasing the tractive force of the roadheader, and solves the problems of the tractive force of the roadheader and the insufficient stability of the machine in the process of...
