Pavement paving equipment for mine roadways

Abstract

The invention relates to pavement paving equipment for mine roadways, comprising two end paving formworks which are symmetrically arranged, wherein a plurality of foldable paving formworks are arranged between the two end paving formworks and integrally hinged with the two end paving formworks; connecting pillars are symmetrically arranged at one sides of the end paving formworks and upper and lower sides of the foldable paving formworks; pinholes are formed on the connecting pillars; the connecting pillars on the end paving formworks and the foldable paving formworks are respectively hinged and connected together through split pins and universal rings; guide grooves for the sliding of guiding steel wire ropes are longitudinally and symmetrically arranged at middle parts of the end paving formworks and the foldable paving formworks; and leading holes for fixing and leading the steel wire ropes are arranged on the end paving formworks. During paving, rapid and accurate paving can be realized through spreading the paving formworks along the guiding steel wire ropes. The device has the advantages of simple structure, convenience for use and good effect and capability of saving the labor intensity of workers and satisfying the use requirements of complicated working conditions such as multiple bends, variable gradients and the like of the roadways.

Description

technical field [0001] The invention relates to a pavement equipment, in particular to a pavement equipment used for laying the pavement of an underground roadway in a coal mine. Background technique [0002] The bottom of coal mine underground roadways is mostly mudstone or shale, which often softens and disintegrates when exposed to water, and forms mudstone muddy matter similar to mud under certain conditions, which is very inconvenient for pedestrians to walk on. The traditional roadway floor mudstone muddy matter The treatment method is to clean up the silt and accumulate it in the open field, then pave the gravel, pour the concrete pavement and maintain it, etc. The main problems are: 1) The concrete pavement pavement period is long, and pedestrians and pedestrians cannot pass through the pavement during the paving process. The opening to traffic will affect the underground production of coal mines; 2) The paving of concrete cannot be recycled, and when the roadway is ...

[0002] The bottom of coal mine underground roadways is mostly mudstone or shale, which often softens and disintegrates when exposed to water, and forms mudstone muddy matter similar to mud under certain conditions, which is very inconvenient for pedestrians to walk on. The traditional roadway floor mudstone muddy matter The treatment method is to clean up the silt and accumulate it in the open field, then pave the gravel, pour the concrete pavement and maintain it, etc. The main problems are: 1) The concrete pavement pavement period is long, and pedestrians and pedestrians cannot pass through the pavement during the paving process. The opening to traffic will affect the underground production of coal mines; 2) The paving of concrete cannot be recycled, and when the roadway is abandoned, the concrete pavement will be scrapped; 3) The process of pouring concrete pavement is complicated, and the labor intensity of workers is high; 4) The comprehensive cost of prefabrication and laying of concrete pavement high
