Problems solved by technology
[0004] 1. The installation of the existing protective devices is cumbersome and requires many workers to help build them, which is time-consuming and laborious;
[0005] 2. When the existing protective device is fixed, the way of fixing it by inserting the fixing rod into the ground is unstable, and it will lead to dumping in windy weather;
[0006] 3. In rainy weather, rainwater drips from around the roof, which not only causes loose drawings near the wellhead, but also cannot automatically and intelligently collect rainwater in rainy weather for daily use by workers;

The invention belongs to the technical field of mineral excavation, and specifically discloses a mine wellhead protection device for a mine hoist, which includes a bottom plate. Fixing rods for fixing the bottom plate are arranged at each top corner of the bottom plate. A guardrail is installed between the guardrails, and the inner side of the guardrail is fixedly supported by a number of support rods to prevent rain and collect water. The invention is scientific and reasonable, and is safe and convenient to use. By protecting the wellhead of a vertical mine, it can effectively prevent The collapse of the wellhead of the mine can also effectively prevent people from falling into the mine. At the same time, it can also effectively prevent rainwater from pouring into the mine in rainy weather, which is convenient for assembling the bottom plate. It is provided with a second screw hole, a second screw and a fastening Nuts are convenient for fixing the bottom plate after assembly, avoiding loosening of the bottom plate during use, and making the assembly of the bottom plate more stable.
Description
Technical field[0001]The invention relates to the technical field of mineral excavation, in particular to a mine wellhead protection device used for a mine hoist.Background technique[0002]Mine is a general term for shafts, chambers, equipment, ground buildings and structures that form the production system of underground coal mines. Mine development can be divided into shaft development, inclined shaft development, flat tunnel development and comprehensive development. After the vertical shaft development, it is necessary To protect the wellhead, on the one hand, avoid the phenomenon of wellhead collapse, on the other hand, avoid the phenomenon of personnel falling;[0003]The existing mine wellhead protection device has the following problems when in use:[0004]1. The installation of the existing protective devices is cumbersome, requiring a lot of workers to help build them together, which takes time and effort;[0005]2. When the existing protective device is fixed, the method of usin...
