Embodiment Construction

[0021] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.

[0022] Hydraulic rock bolter for coal mine is mainly composed of frame, workbench, temporary support, ceiling, connecting rod mechanism, slide rail, coiled cable, hydraulic system, electrical system, anchor drilling system, dust removal system, etc. Its main technical parameters are as follows:

[0023] Adapt to roadway height (mm): 3200~5100;

[0024] Adapt to roadway width (mm): 5000~5500;

[0025] Maximum mobilization speed (m / min): 25;

[0026] Rock hardness: f≤7 comprehensive rock formation;

[0027] Adapt to the inclination angle of the roadway (°): ≤16°;

[0028] Minimum ground clearance (mm): 300mm;

[0029] Installed power (kW): 2×55;

[0030] Number of drill arms: 5;

[0031] Maximum drilling depth (mm): 2600;

[0032] Grid voltage level (V): 1140 / 660.

[0033] 1. Arrangement of five drill arms.

[0034] Five drilling arms are a...

Abstract

The invention belongs to the technical field of anchor drills for underground excavation roadway support in coal mines, in particular relating to a hydraulic five-arm anchor drill for the coal mine. With the adoption of the hydraulic five-arm anchor drill provided by the invention, the problem of low supporting efficiency caused by that the traditional four-arm anchor drill for the coal mine cannot be applicable to roadway support in the need of five-anchor-rod support can be solved. The hydraulic five-arm anchor drill comprises an anchor drilling system, wherein the anchor drilling system comprises five drilling arms; three drilling arms are mounted on a fixed sliding rail; and two drilling arms are respectively mounted on a left-sliding sliding rail and a right-sliding sliding rail. The hydraulic five-arm anchor drill provided by the invention has the advantages of being more suitable for the roadway supported by using the five anchor rods, being more common in application, and better meeting requirements for efficiently and rapidly tunneling mine coal faces with high yield. The hydraulic five-arm anchor drill provided by the invention can be used with a continuous miner so that the driving speed can be increased to 1.7 times that of the four-arm anchor drill used with the continuous miner. Therefore, the contradiction between excavating and supporting can be solved and the hydraulic five-arm anchor drill provided by the invention has a wide market prospect.

Description

technical field [0001] The invention belongs to the technical field of a rock bolt drilling vehicle for roadway support in underground coal mines, and in particular relates to a hydraulic five-arm bolt drilling vehicle for coal mines. Background technique [0002] Existing rock bolting rigs, such as the Chinese patent 200410012344.0 that the applicant has applied for and obtained authorization, discloses a crawler-type walking rock bolting rig, which adopts explosion-proof design, reasonable structure, large bearing capacity, and can move freely Free and reliable, fast anchor drilling speed, high efficiency, good quality, high safety factor, and can adapt to work in harsh environments. It is an ideal safety support equipment for underground mining. The car can also be used for mining support anchor drilling operations of other minerals. [0003] With the increase of the depth of the roadway and the deterioration of the roof condition of the roadway, more and more roadways n...
