The electro-hydraulic anchor protection control double basket type two arm anchor cable anchor rod drill truck includes a walking chassis, a vertical lifting platform, a rear machine frame, a left anchor protection large arm, a right anchor protection large arm, an advance support device and an automatic cable winding mechanism, wherein the vertical lifting platform is arranged right above the walking chassis to realize vertical lifting and lowering, a walking reducer is installed on the rear side of the walking chassis, a guide wheel is installed on the front side of the walking chassis, the vertical lifting platform is symmetrically provided with the left anchor protection large arm and the right anchor protection large arm which can realize height adjustment and swing adjustment on both sides, the advance support device is hinged to the front end of the vertical lifting platform, the rear machine frame is arranged inthe rear of the walking chassis, a motor, a pump station and an oil tank are sequentially installed on the top left of the rear machine frame to form a power system, a driving room and an electric control box are arranged above the power system, the automatic cable winding mechanism and a cable winding guide supporting roller group are installed on the left side of the driving room, and a rear stabilized shoe is installed at the bottom of the rear machine frame.

Description

technical field [0001] The invention belongs to the technical field of equipment for drilling holes, installing and fastening anchor cables and bolts, and in particular relates to an electro-hydraulic anchor protection control double-basket type two-arm anchor cable and bolt drilling rig. Background technique [0002] At present, the conditions of the roof and side walls are poor during the roadway excavation of most coal mines in China. The empty roof distance is generally not more than 3 meters, and most of them are 1-2 meters. For excavation, bolt and cable support work is carried out manually, the labor intensity is relatively high, the working conditions are relatively harsh, the efficiency is low, and the risk factor is high. Some coal mines use a self-moving fully hydraulic two-arm rock bolter. This equipment is flexible and maneuverable. It can enter the empty roof area from the roadheader or continuous miner to carry out anchor protection operations. It improves th...

AI Technical Summary

Problems solved by technology

[0004] (1) It is difficult to support the upper and lower side bolts of the roadway, and the height of the upper side bolts is relatively high. Operators need to use other climbing equipment to perform operations such as drug release. The mechanization of bolting cannot be fully realized, and it is still necessary to manually hold the single-body bolter to complete the bolting operation. The efficiency is low, the operation safety is poor, and the operation lags behind, which affects the construction progress;

[0005] (2) The manipulator for anchoring and drilling rig has low degrees of freedom and poor adaptability, and cannot realize multi-angle and large-scale adjustment. The anchoring and protection of the drilling rig covers a limited section of the roadway, which cannot meet the requirements for anchoring and protection for different conditions and different attitudes of the roadway;

[0006] (3) The platform lifting mechanism is mostly a four-link lifting mechanism, and its lifting trajectory is an approximate linear motion trajectory, which cannot realize the vertical lifting of the platform, and there is a large deviation. The use of platform lifting cannot meet the needs of anchor rods in rows, and needs to be adjusted every time Compensation action of the drill stand to achieve front and rear rows

[0007] (4) The traveling mechanism of the drilling rig is controlled by a hydraulic system, which has a low degree of automation, poor synchronization of the left and right crawlers, no automatic step-fixing function, and poor safety and reliability of the equipment;

[0008] (6) When the horizontal support height of the side rail reaches 700-4200mm, it is one model, and when the support reaches 1000-4500mm, it is another model, which brings greater difficulty to production organization and spare parts supply

[0009] (5) The drilling rig has no stabilizing mechanism, and it is difficult to locate when drilling, requiring manual assistance. The labor intensity of personnel is high, and there are potential safety hazards
