Description

Technical Field

[0001] The present invention relates to the technical field of bolt drill jumbos, and particularly to a fully automatic bolt drill jumbo for coal mines. Background Art

[0002] At present, there are two forms of ordinary hydraulic bolt drill jumbos on the market. One is the small swing arm + integral lifting platform type, and the other is the large swing arm type. No matter which form it is, automatic hole finding cannot be achieved, and multiple actions such as swing angle adjustment, compensation, and leveling are required to find the hole, resulting in low efficiency. There are also problems such as manual rod connection, disassembly of drill rods, climbing the boom, applying anchoring agent, moving the drill arm, installing bolts, and the small size of the drill rod removing device, which cannot pass through the tray.

[0003] Based on the above requirements of coal mines and the problems existing in ordinary hydraulic bolt drill jumbos, it is trending towards the direction of automation. Currently, there are two forms of automation structures on the market:

[0004] One is that the mesh storage bin is placed in front, used to store diamond meshes, and automatic mesh laying is carried out as the drill jumbo moves; two extended drill arms are arranged, and two drill boxes are installed on the drill arms, respectively used for drilling and installing bolts. The drill arms can move on the slide rails to realize the installation of top bolts; two chain-type bolt bins are arranged at the rear, and the bolts use front-mounted resin anchoring agents.

[0005] The other is a drill jumbo with an automatic mesh laying robotic arm in a swing arm form. The robotic arm is installed with a manipulator to clamp the steel mesh for automatic mesh laying; a swing arm type drill arm is arranged for drilling and installing bolts, and a chain-type bolt bin is arranged at the rear of the drill arm; a resin anchoring agent spraying device is installed at the rear of the drill jumbo to spray and install the resin anchoring agent.

[0006] For the first above-mentioned structure: The limitations of automatic mesh laying are relatively large. According to the requirements of GBT35056-2018 "Technical Specification for Bolt Support in Coal Mine Roadways", standard support components also need steel belts, and this structure cannot achieve the installation of steel belts; since front-mounted resin anchoring agent bolts are used, the length of the bolts is increased invisibly, resulting in the same increase in the length of the drill arms, and thus the overall height of the machine is very high, making it impossible to use in small-height roadways, and the applicable range is limited; two drill boxes are arranged on the drill arms, and the two drill boxes need to be alternately moved to realize drilling and installing bolts, and the process is cumbersome; a chain-type bolt bin is used, and the positioning is inaccurate during rotation and movement, and it is difficult to achieve precise rod picking by the manipulator; the two drill arms adopt a fixed slide rail type, and the drill arms cannot realize the support of side bolts, and bolts need to be supplemented later, which cannot meet the requirements of rapid tunneling support.

[0007] The second structure described above: Similar to the first solution, this structure is also unable to install steel belts and can only install steel mesh; since both the automatic mesh-laying robotic arm and the drilling arm are swing-arm types, it is very difficult to accurately position the two swing arms during mesh-laying and drilling, which is time-consuming; because the structure consists of one mesh-laying robotic arm and one drilling arm, this will result in low drilling efficiency in the same roadway and cannot meet the requirements of rapid tunneling support.

[0008] In summary, the present application proposes a fully automatic bolt drill rig for coal mines, which can achieve mechanized operations such as one-time positioning, automatic positioning of bolt spacing, automatic mesh-laying, automatic hole-finding, automatic loading and unloading of drill pipes, automatic drilling, automatic loading of resin anchoring agents, automatic installation of bolts, and automatic stirring and pre-tightening. It fundamentally solves the deficiencies existing in current bolt support operations and is a rapid support equipment that can truly reduce the number of personnel, improve efficiency, provide rapid support, replace manual labor with mechanization, and reduce the number of personnel through automation, ensuring the tunneling speed and support quality.

Both sets of intelligent control systems can control the walking of the jumbo, the stabilization of the outriggers 903, the telescoping of the platform, the automatic mesh laying, and the lifting of the lifting device 3. Inside the electric control box 103, there are electrical components such as PLC, which receive and issue signals to control the actions of each valve, and can preset relevant parameters according to the actual working conditions. In addition, the right remote control system controls the right automatic drill-anchor mechanism 5, and the left remote control system controls the left automatic drill-anchor mechanism 6, and preset the interference control conditions in advance to avoid the interference of the two sets of automated drill arms. The intelligent control system can also realize fault diagnosis, which is convenient for maintenance.
