Self-propelled type temporary support and anchor support machine for coal mine roadway

Abstract

The invention provides a self-propelled type temporary support and anchor support machine for a coal mine roadway. The self-propelled type temporary support and anchor support machine for the coal mine roadway is mainly composed of a walking support module, a supporting cross beam module, a lead shield beam module, an anchor drilling machine module and a drilling machine walking module. The walking support module mainly comprises two walking supports which are parallel. The supporting transverse beam module comprises a main transverse beam and two auxiliary transverse beams; the main transverse beam and the auxiliary transverse beams are fixedly connected with the walking support module through bolts. The lead shield beam module comprises a lead shield beam and a hydraulic oil cylinder, the lead shield beam and the hydraulic oil cylinder are hinged through a pin shaft, and the lead shield beam module is connected with the main transverse beam through a pin shaft. The anchor drilling machine module is fixedly connected with the drilling machine walking module through bolts. The drilling machine walking module is installed on a guide rail of the main transverse beam through rail sliding blocks. According to the self-propelled type temporary support and anchor support machine for the coal mine roadway, synchronous and continuous operation of the fully-mechanized excavating work and support and anchor support work for the coal mine roadway can be achieved, the excavating efficiency for the coal mine roadway is improved, labor intensity is relieved, and safety of support and anchor support for the coal mine roadway is improved.

Description

technical field [0001] The invention relates to the technical field of temporary support and anchor protection of coal mine roadways, in particular to a self-propelled coal mine roadway temporary support anchor protection machine. Background technique [0002] The "Coal Mine Safety Regulations" stipulates that when mining tunnels in soft coal, rock formations or quicksand formations and geological fracture zones, forward support or other measures must be taken. [0003] In the process of coal mining, the roadway excavation work is the prerequisite for other follow-up work. In recent years, with the increasing popularity of fully mechanized excavators, the single entry level of the coal mine roadway fully mechanized mining face has greatly improved compared with the traditional blasting method. Big improvement. At present, the more popular fully-mechanized excavation technology is: the fully-mechanized excavation machine stops after driving 0.8-1.2 meters, and is supported b...

Problems solved by technology

At present, the more popular fully-mechanized excavation technology is: the fully-mechanized excavation machine stops after driving 0.8-1.2 meters, and is supported by artificial bolts, anchor cables or shed beams. This working method has poor continuity and greatly affects the mechanized excavation. The excavation efficiency of the machine is low, the operation efficiency is low, the labor intensity of the operators is high, and there are also great hidden dangers to personal safety.
