Telescopic full-shield full-section coal mine digging and anchoring equipment

Abstract

The invention belongs to the field of engineering machinery, and particularly relates to telescopic full-shield full-section coal mine digging and anchoring equipment which comprises a digging and anchoring all-in-one machine body, and a telescopic anchor rod drilling mechanism, a telescopic lateral shield mechanism and a telescopic temporary supporting mechanism are arranged on the digging and anchoring all-in-one machine body. By arranging the supplementary supporting anchor rod drilling unit on the digging and anchoring all-in-one machine body, the top anchor supplementary supporting distance can be greatly shortened; through the arrangement of the telescopic anchor rod drilling mechanism, the unsupported roof distance can be greatly reduced; through the arrangement of the telescopic lateral shield mechanism, the danger that the two side walls of the cut roadway deviate and fall off can be effectively prevented; and through the arrangement of the telescopic temporary support mechanism, the effect of temporary support forward movement can be effectively achieved. Through cooperative arrangement of the telescopic anchor rod drilling mechanism, the telescopic lateral shield mechanism and the telescopic temporary supporting mechanism, a full-shield protection mode is achieved, and front operators can be effectively isolated from danger.

Description

technical field [0001] The invention belongs to the field of construction machinery, in particular to a colliery anchor digging equipment with a retractable full shield and full section. Background technique [0002] Existing digging and anchoring integrated systems, such as figure 1 As shown in the figure, it generally includes the main body 001 of the bolt-digging integrated machine and the bolt transporting drilling rig 002, which are connected in the front and back. The telescopic platform 0014 and the anchor rod drill 0015 are provided on the anchor rod transport drill rig 002. The anchor rod transport drill truck roof anchor rod drill 0021 and the anchor rod transport drill rig 0022 are provided. The existing integrated system of digging and anchoring generally has the following problems: [0003] 1. Because the cutting drum of the cutting part 0011 is a non-crossable part, when it starts to drive forward, the empty top distance X generally exceeds two meters; [00...

AI Technical Summary

Problems solved by technology

[0004] 2. The protection area is small, and the geological structure of domestic coal mines is complex. The roof is prone to coal drop and roof fall, and the side walls are prone to geological hazards such as partial side, which greatly increases the safety risk of operators;

[0005] 3. Due to the location of the anchor drill configuration, that is, according to the setting form of the bolt drill 0013 on the top of the bolter and the bolt drill 0021 on the top of the anchor transport drill vehicle, the top anchor repair distance Y is delayed by several row distances, which cannot be Provide reliable protection for equipment and personnel
