Description

Technical Field

[0001] The invention relates to the technical field of tunnel support devices, in particular to a detachable safety support device for mine tunnels. Background Art

[0002] Mine tunnels are a general term for various underground spaces that are excavated in different rocks along different directions, at different inclinations, in different sections and lengths, serving different ranges and used for different purposes. During the mining process of the mine, timely measures must be taken to erect temporary supports to ensure that the tunnels will not collapse and to ensure the safety of the lives of construction workers. Therefore, a safety support device for mine tunnels is needed.

[0003] The Chinese patent with the authorization publication number CN220015212U discloses a mine tunnel support device, wherein the support device is provided with several groups in the mine tunnel, and each group of support devices includes a first support mechanism and a second support mechanism, wherein the first support mechanism includes a top plate and a bottom plate, and a support assembly is fixedly connected between the top plate and the bottom plate; the second support mechanism includes two groups of longitudinal support frames, and each group of longitudinal support frames includes a base and a top seat, and a hydraulic lifting part is fixedly provided above the base, and lateral force-bearing parts are fixedly provided on both sides of the hydraulic lifting part on the upper part of the base. The two support modes of the utility model are organically combined, which greatly improves the support effect of the support device on the inside of the tunnel; secondly, the lateral force-bearing part will deflect under extrusion and squeeze the side wall, so that the side wall supports the second support mechanism, thereby avoiding the situation that the pressure from the top wall of the tunnel on the tunnel support device is all concentrated on the tunnel foundation, thereby improving the overall effect of the device.

[0004] Although the mine tunnel support device mentioned above can avoid the situation where the pressure from the tunnel top wall on the tunnel support device is all concentrated on the tunnel foundation, in general, during the temporary support process, multiple sheds need to be deployed to coordinate support operations to ensure the safety and stability of the overall support of the section. The support structure is difficult to ensure integrity and continuity, which can easily lead to the risk of the top beam support being overturned as a whole due to the unbalanced force from inside or outside the tunnel;

[0005] Due to the lack of combination of support structure and dust suppression, there is a lot of dust in the mine tunnels. If the dust is not suppressed in the support structure, the workers will be harmed by the dust, affecting their physical and mental health as well as work efficiency. For this reason, we propose a method with. Summary of the invention

The water can be transported to the atomizing nozzle through a pump body and a connecting pipe.

There is a lot of dust in the mine tunnels. If the dust is not suppressed in the support mechanism, the workers will be harmed by the dust, affecting the workers' physical and mental health as well as work efficiency.
