Problems solved by technology
[0003] When mining coal, because the coal is located below the ground, it is necessary to work below the ground. Due to continuous excavation, the thickness between the ground and the ground is reduced. If gravity passes above the ground, or the thickness collapses, it is easy It will cause harm to the operating personnel. Therefore, it is necessary to provide good support for the mining part. Traditionally, ordinary support frames are used, and different numbers of support frames are used according to the position of support. Since the support frames are scattered, it is not convenient to carry out overall moving, and it is inconvenient to adjust the height of the support, and it is also inconvenient to adjust the angle. Therefore, in order to solve these problems, it is necessary to design a mechanical support device for coal mining

The invention discloses a mechanical supporting device for coal mining. The mechanical supporting device comprises a strip-shaped bearing base, wherein a mechanical supporting mechanism is arranged onthe upper surface of the strip-shaped bearing base, and a movable supporting mechanism is arranged on the lower surface of the strip-shaped bearing base. The mechanical supporting device has the advantages that the mechanical supporting device is good in use effect, facilitates adjusting based on fixed angles, facilitates supporting position adjustment according to important supporting positions,facilitates manual screwing, extrusion and supporting according to the size of holes and facilitates good protection to workers under the device.
Description
technical field [0001] The invention relates to the support field, in particular to a mechanical support device for coal mining. Background technique [0002] Support is to carry foreign objects in certain places that need to be fixed. [0003] When mining coal, because the coal is located below the ground, it is necessary to work below the ground. Due to continuous excavation, the thickness between the ground and the ground is reduced. If gravity passes above the ground, or the thickness collapses, it is easy It will cause harm to the operating personnel. Therefore, it is necessary to provide good support for the mining part. Traditionally, ordinary support frames are used, and different numbers of support frames are used according to the position of support. Since the support frames are scattered, it is not convenient to carry out overall It is inconvenient to adjust the height of the support, and it is also inconvenient to adjust the angle. Therefore, in order to solve t...
