Problems solved by technology
[0004] However, when the existing hydraulic support is in use, the area it can support is very small, and as the coal mining machine moves, the existing hydraulic support only moves synchronously with the coal mining machine, and when the hydraulic support moves, The top of the coal mine needs to be supported in time, which leads to the need to use hydraulic supports for support, resulting in increased support costs. At the same time, when the coal mining machinery is working, the hydraulic supports are also supporting the coal mine. When a landslide occurs, it cannot be monitored in time. Occurrence of landslide accident

Embodiment Construction
[0024] The present invention is specifically described below in conjunction with accompanying drawing, as Figure 1-7 As shown, in this implementation:
[0025] First, place the device on the side of the coal mining machine in the coal mine, and connect the device to an external power source. When the coal mining machine is working, the device moves synchronously with the lateral movement of the coal mining machine;
[0026] Firstly control the work of the cover type hydraulic support 1 3 and the cover type hydraulic support 2 25 to support the top of the coal mine. When the coal mining machine moves, the cover type hydraulic support 1 3 will be lowered at this time, and at the same time, the support hydraulic cylinder 41 will be controlled to shrink to support The base 42 rises to make the wheels 40 contact the coal mine ground. At this time, the rotating motor 18 is controlled to rotate, and the rotating motor 18 rotates to drive the screw rod 19 to rotate. Translate on the...

The invention discloses a supporting platform device for a coal mine drilling machine, comprising a base, the base is provided with a fixed support device, the fixed support device is provided with a support plate lifting device, and the base is provided with a sliding device, The sliding device is provided with a movable support device, a landslide monitoring device is provided above the base, and a mobile support device is provided below the base. The base supports the support plate to the top of the coal mine through two hydraulic supports. The rotation enables the movable support plate to move in translation with the movement of the drilling machine, so that the device can move with the movement of the drilling machine, preventing damage to the drilling machine caused by landslides during drilling, and at the same time, it can monitor whether the mine occurs in real time. collapse. The invention has the advantages of simple structure and strong practicability.
Description
technical field [0001] The invention relates to the field of equipment related to coal mine drilling support, in particular to a support platform device for coal mine drilling machinery. Background technique [0002] The hydraulic support is a structure used to control the mine pressure of the coal mining face. It is a hydraulic power device that uses liquid pressure to generate support force and realizes automatic shifting for roof support and management. It is indispensable for comprehensive mechanized coal mining. Missing supporting equipment. The front beam of the common hydraulic support cannot be extended outward. When the area that needs to be supported by the front beam is relatively large, and a hydraulic support cannot be placed on the corresponding place on the ground, it will affect the construction. It is necessary to clear the obstacles on the ground first. , and then install a hydraulic support, which is not only time-consuming and labor-intensive, but also i...
