Description

A structure in which a magnetic starter and a follow-up operating platform are installed on a telescopic platform

technical field

The present invention relates to a structural arrangement for installation of a magnetic starter and an operating platform, in particular to a structure in which a magnetic starter and a front drill arm operating platform are installed on a telescopic platform. This arrangement is suitable for coal mines or non-coal mines, etc. Narrow roadway with compact drilling (anchor) all-in-one unit.

Background technique

Coal mine excavation generally has tension in replacement, and the excavation is lagging behind in coal mining, and the excavation has a strong advanced nature. The main reason for the imbalance of excavation is that the excavation surface is often lagging behind the layout of the coal mining surface due to the small excavation footage and slow progress. , resulting in mining imbalance. Gas in mines is an important cause of unbalanced mining. At present, the new national "Coal Mine Safety Regulations" requires that for the underground gas drainage system of high-gas mines, the gas in the mining face should be drained at a high level to reduce the gas concentration in the mining process of the working face and reduce the gas exceeding the limit. The top is located in the fissure zone formed by the impact of mining to excavate a special drainage roadway, that is, a high drainage roadway. After the coal seam gas is released, the roadway will be closed and abandoned. Therefore, the roadway section of the high drainage roadway is generally designed to be 6 to 9 square meters. There is no hard rock excavation equipment suitable for narrow coal mine roadways at home and abroad, which is an international blank area. According to the data provided by the coal industry, there are 560,000 meters of such high (bottom) pumping roadway excavation in coal mines in China alone every year. According to the current status of equipment, the section of the roadway is enlarged to 9-12 square meters, and the construction cost is doubled. The coal industry alone wastes more than 5.6 billion in the country every year. The excavation footage is reduced, and the entire industry is out of balance.

Contents of the invention

Aiming at the above-mentioned problems in the prior art, the present invention provides a novel structure in which the magnetic starter and the follow-up console are installed on the telescopic platform.

The technical solution adopted by the present invention is: a structure in which the magnetic starter and the follow-up operating platform are installed on the telescopic platform, and the telescopic platform includes a fixed platform fixed on the frame and a telescopic extension connected to the fixed platform. Out of the platform; the extended platform includes at least one secondary telescopic tube, a tertiary telescopic tube that is movably connected with the secondary telescopic tube, and a primary telescopic tube that is movably connected with the fixed platform, and one end of the tertiary telescopic tube is provided with Drill boom or bolt arm mounting seat, the three-stage telescopic tube is connected to the hydraulic cylinder installed inside or outside the fixed platform through the piston push rod, and the magnetic starter and the tail bolter operating platform are fixed fixedly arranged at the front end of the fixed platform On the top surface, a supporting plate is fixedly connected to the mounting base of the drilling arm or the rocker arm, and the front drilling arm operating platform is fixedly arranged on the supporting plate.

The invention increases the research and development and investment of advanced equipment. In the coal mine production process, it is necessary to speed up the introduction of advanced scientific and technological equipment, and to be able to operate it skillfully, so as to ensure that the equipment can better exert its performance and achieve its expected effect. , not only helps to effectively improve the efficiency of mining and excavation, but also can effectively ensure the safety of personnel.

In non-metallic mines such as gold mines, tungsten mines, etc., where the ore veins are in the form of bands, it is required to have less roadway sections, low mining costs, and fast roadway excavation speed.

The horizontal load-bearing multi-section telescopic platform has not been used before, so there is no structure in which the magnetic starter and the operating table are installed on the telescopic platform.

In order to reduce the volume of the machine, the structure of the drilling and mounting (anchor) integrated machine is more compact, and it is suitable for roadways with fewer roadway sections. A structure in which the magnetic starter and the operating console are installed on the telescopic platform, and the magnetic starter is arranged on the fixed side of the telescopic platform. The front part of the platform is tightened by bolts, so that disassembly and assembly are simple and convenient.

Arrange the tail bolter operating table at the rear of the fixed platform of the telescopic platform, and tighten it with bolts, so that the bolter can be seen conveniently and intuitively during actual operation, and the disassembly and assembly are also simple and convenient for storage.

That is to say, the magnetic starter and the tail bolter console are arranged on the fixed platform of the telescopic platform, and the front drill boom console is arranged on the extended platform of the telescopic platform, which can save space, and the appearance is also beautiful and compact, and it is also convenient operate.

The telescopic platform of the present invention has a mounting seat connected with the magnetic starter, the airborne bolter operating platform at the tail and the front drilling arm operating platform, and the connection is safe and reliable.

The distance between the rear bolter operating table and the bolter is short, and the operator stands on the ground to operate, which is flexible and has good sightlines. The drill bit of the bolter can be quickly positioned, and the work efficiency of the bolter is improved.
