Problems solved by technology

[0005] In view of this, the present invention aims to propose an advanced support mechanism and a roadheader equipped with the advance support mechanism, so as to solve the problem that the empty head distance of the advance support mechanism is relatively small and installed on the roadhead machine during the existing roadway construction process. The cutting part affects the work of the roadheader and other issues

Embodiment Construction

[0052] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be pointed out that the description and sequence of specific structures in this section are only descriptions of specific embodiments, and should not be considered as limiting the protection scope of the present invention.

[0053] In the embodiment of the present invention, by changing the original advance support mechanism in the roadway, the previous manual support or the support structure provided at the cutting part of the roadheader is changed to be installed on the back support of the roadheader, and on the back support of the roadheader. A mounting seat is provided, and a telescopic main arm is installed on the mounting seat. The telescopic main arm can be raised and lowered and rotated through the lifting c...

Abstract

The invention relates to a pre-supporting mechanism and a tunneling machine. The pre-supporting mechanism is mounted on a rear support of the tunneling machine through a mounting seat, a telescopic main arm is arranged on the mounting seat, and a supporting top plate is hinged at the top of the telescopic main arm. The mounting seat is arranged on the rear support of the tunneling machine, the telescopic main arm is connected on the mounting seat, and the supporting top plate is hinged at the top of the telescopic main arm, so that the pre-supporting mechanism can swing without swinging along with a cutting portion, working of the tunneling machine is not affected, demounting of a cover plate of the tunneling machine is not impeded, and system maintenance of the tunneling machine is not affected; the pre-supporting mechanism does not need manual supporting, so that working intensity is reduced, and safety of working personnel can be effectively protected.

Description

technical field [0001] The invention relates to an advanced support technology for an empty roof in the roadway construction process, in particular to an advanced support mechanism and a roadheader equipped with the advanced support mechanism. Background technique [0002] At present, the temporary support after excavation of the roadway is basically manual. After excavation, the front beam is erected, which is labor-intensive. Most of the front beams are two steel pipes, the support strength is low, and the safety system is even lower. [0003] Therefore, part of the advanced support mechanism uses an airborne structure, which is specifically installed on both sides of the cutting part. If the head is too close, there are potential safety hazards, and it is far from meeting the requirements of coal mines that the larger the distance between the head and the better, and after being installed on both sides of the cutting part, when the roadheader is working, the advance suppo...
