Problems solved by technology

[0002] Most of the current coal mine roadway excavation equipment and anchoring equipment are operated independently. Even if there is a certain degree of combination, due to the inevitable contradiction between the space position requirements between the excavation and anchoring, it is impossible to maximize their respective functions. The best performance, its disadvantages are: 1. After a certain progress in the excavation, the roadheader must withdraw to allow the bolter to enter the anchoring operation. After the anchoring operation is completed, the roadheader can enter the next round of excavation. This method of operation has seriously affected the excavation efficiency; 2. The roadheader generally excavates a fuselage length before the bolter can be anchored, resulting in a longer empty head distance, especially in the case of poor geological conditions, which increases the danger of operators 3. The current roadheaders are all open type. During the tunneling operation of the coal roadway, even if the ventilation conditions are good, it will inevitably produce a huge amount of dust, which is not conducive to the safety of the workers. Healthy; 4. The operation method of the rock bolt rig has not formed a large-scale and modularized structure, resulting in longer anchoring time and low anchoring efficiency; 5. The operators do not have certain protection measures during the operation; 6. The transportation and lifting of the mesh Most of them rely on manpower, and the labor intensity of the operators is relatively high

Abstract

The invention relates to coal mine roadway tunneling machinery, in particular to a fully sealed coal roadway tunneling and anchoring synchronous machine, comprising a tunneling device, a sealing and dust removing device, an anchoring device, a coal loading and conveying device, a power system and a hydraulic system, wherein the tunneling device comprises a body part, a telescopic cutting part arranged at the front end of the body part, a walking part arranged at the lower part of the body part and a rear support part arranged at the rear end of the body part; the anchoring device comprises at least one first anchor rod drill carriage; the first anchor rod drill carriage is arranged between the cutting part of the tunneling device and the power system; other anchor rod drill carriages are arranged behind the power system sequentially; each anchor rod drill carriage comprises a frame, an anchor rod drilling machine group fixedly arranged on the frame, wheels arranged at the four corners of the lower part of the frame and a hydraulic oil cylinder; the body part of the tunneling device is in overlap joint with the two sides of the frame of the first anchor rod drill carriage through a sliding rail and is fixedly connected with a dragging oil cylinder; and the anchor rod drill carriages are hinged with one another. The fully sealed coal roadway tunneling and anchoring synchronous machine is unique in design, reasonable in structure, high in the degree of automation, efficient and safe and is very suitable for extended application.

Description

technical field [0001] The invention relates to a coal mine roadway excavation machine, in particular to a fully sealed coal roadway bolt digging synchronous machine, especially suitable for the integrated synchronous operation of driving and anchoring in an all-coal roadway or a coal roadway with a hardness f<4. Background technique [0002] Most of the current coal mine roadway excavation equipment and anchoring equipment are operated independently. Even if there is a certain degree of combination, due to the inevitable contradiction between the space position requirements between the excavation and anchoring, it is impossible to maximize their respective functions. The best performance, its disadvantages are: 1. After a certain progress in the excavation, the roadheader must withdraw to allow the bolter to enter the anchoring operation. After the anchoring operation is completed, the roadheader can enter the next round of excavation. This method of operation has seriou...
