Onboard supporting platform system for heading machine and construction method of onboard supporting platform system

Abstract

The invention relates to an onboard supporting platform system for a heading machine. Comprising a heading machine, a multi-stage telescopic mechanism, a vertical supporting device and a top frame mechanism, wherein one end of the multi-stage telescopic mechanism is fixedly connected to two sides of a crawler chassis of the heading machine; the vertical supporting device is connected to the other end of the multi-stage telescopic mechanism; the top frame mechanism is fixedly connected to the top end of the vertical supporting device; the lifting platform is arranged below the top frame mechanism; the operation table is arranged in the heading machine; the multi-stage telescopic mechanism stretches out and draws back in the horizontal direction of the heading machine; an adjusting device is arranged between the vertical supporting device and the multi-stage telescopic mechanism; the adjusting device can be adjusted along the width direction and the height direction of the heading machine; the operation table provides hydraulic control for the multi-stage telescopic mechanism, the vertical supporting device, the top frame mechanism and the lifting platform. The invention further relates to a construction method, all-directional adjustment of the lifting platform and the top frame mechanism can be achieved through hydraulic control, safety accidents are reduced, the adjustment time is shortened, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of roadway support, in particular to an airborne support platform system for a roadheader and a construction method thereof. Background technique [0002] Bolt support is a very effective support method for coal mine roadways. Bolts can change the mechanical state of the surrounding rock itself, thereby achieving the purpose of maintaining the stability of the roadway. At present, the roadheader needs to stop working after one working step forward. After the manual operation of the rock bolter to carry out the bolting operation in the empty roof area, the roadheader starts the next work step. The work progress is slow, the labor intensity of the workers is high and there are great safety hazards. [0003] In the existing roadheader airborne temporary support device, the top frame is installed on the flip frame. When support is required, the flip frame body is turned from back to front, and then the top fram...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to solve the low support strength in the prior art, the difficulty in connecting the staff and equipment to the top, especially the pre-tightening and cutting of the anchor cable at the top, and the difficulty in the construction and installation of the anchor rod and anchor cable at the shoulder socket. Large, low-efficiency layered excavation technology can only be used, and full-section construction cannot be carried out.
