Problems solved by technology

However, the connection between the temporary support device of the existing structure and the permanent support operation of the roadway is inconsistent, which often results in empty top operations and high safety hazards; and the efficiency of the roadheader can only be 20% to 25%, and the tunneling efficiency is low, which seriously restricts The succession and normal production of coal roadway working faces in coal mines have become a common bottleneck problem in coal mines in my country.

Abstract

The invention relates to a roadway lapping auxiliary device, which solves the problems that permanent support operation can be carried out only when a heading machine stops and retreats in the prior art, the connection between an existing temporary support device and the roadway permanent support operation is not coherent, potential safety hazards exist, and the heading efficiency is low. Comprising a finger shield protecting plate, the finger shield protecting plate is connected with a supporting top beam of a temporary supporting device, an anchor net lifting frame is arranged below the finger shield protecting plate, net supporting lifting mechanisms are arranged at the two ends of the anchor net lifting frame respectively, and the telescopic ends of the net supporting lifting mechanisms are connected with the end of the anchor net lifting frame; and the fixed ends of the supporting net lifting mechanisms are respectively connected with the side parts of the temporary supporting devices. The temporary supporting device is reasonable in design and compact in structure, and can realize seamless connection between temporary supporting and permanent supporting when the temporary supporting device is used for shield tunneling operation and continuous operation, so that tunneling and permanent supporting are performed in parallel, the tunneling efficiency is improved, a top plate is prevented from sinking, and the supporting quality of a roadway is ensured.

Description

technical field [0001] The invention belongs to the technical field of roadway excavation auxiliary equipment, in particular to a device that can realize the seamless connection between the temporary support and the permanent support when the temporary support device covers the continuous operation of the excavation operation, so that the excavation and the permanent support can be carried out in parallel It is an auxiliary device for roadway laying to improve the efficiency of tunneling, avoid roof sinking, and ensure the quality of roadway support. Background technique [0002] Mining operation and tunneling operation are two key links in coal mine production. With the rapid development of technical equipment, the level of fully mechanized mining in my country has been greatly improved. However, the substantial increase in coal mining output at the working face has also increased the consumption of the roadway, which has led to the problem that the speed of roadway excavat...
