Device integrating pneumatic conveying, fully-mechanized excavating and supporting

Abstract

The invention discloses a device integrating pneumatic conveying, fully-mechanized excavating and supporting. The device comprises a rail, a pneumatic traction device and a supporting device, wherein the rail is fixedly mounted at the top of a tunnel, the pneumatic traction device is mounted on the rail, the supporting device is driven by the pneumatic traction device to move along the rail, the support device comprises a supporting platform, a cantilever and a bottom rack for being hung on the rail, one end of the cantilever is hinged to the bottom rack, and the other end of the cantilever is connected with the supporting platform; a first support air cylinder is connected to the lower portion of the supporting platform, and the push rod of the first support air cylinder extends downwardly and can be supported on the ground; one end of the cylinder barrel of a second support air cylinder is hinged to the bottom rack, and the push rod of the second support air cylinder is hinged to the lower portion of the cantilever. The device integrating pneumatic conveying, fully-mechanized excavating and supporting can move on the rail to an appointed supporting operation positon to perform supporting operation and is affected by tunnel terrain.

Description

technical field [0001] The invention relates to roadway support equipment, in particular to a pneumatically transported fully mechanized excavation and support integrated device. Background technique [0002] At present, comprehensive mechanized excavation methods are commonly used in coal mine underground roadways. During fully mechanized excavation, support devices are usually installed on the roadheader. For example, Chinese patent CN104500086A discloses a roadway unmanned and bolt-digging integrated machine, and its supporting system is driven by the crawler belt of the roadheader to move on the ground of the roadway. This support system that walks on the ground is easily affected by the ground terrain of the roadway, and the balance of the support system is poor when it works. In addition, during the movement of the ground, a large roadway space is occupied, and if other equipment or other workers are installed in the roadway space, the transportation of the support s...

AI Technical Summary

Problems solved by technology

Although this device does not occupy the ground space during transportation, when the support device is working, the support device needs to be removed from the pneumatic traction device, placed on the ground, and finally unfolded into a support umbrella layer by layer to complete the support action , In addition, it must be reinstalled on the traction device after being stowed away, which increases the process of support work, and in fact cannot achieve the real integration of transportation and support

And its supporting device includes a link mechanism composed of multi-section connecting rods. These link mechanisms include multiple hinge points. Wear between the rod and the hinge shaft reduces the stability of the support device in use

In addition, because there are too many linkage mechanisms, factors such as the degree of freedom of rotation need to be considered in the design, so the size of the support device and the proportion of each component will be more restricted, resulting in poor applicability
