Description

Technical Field

[0001] This utility model relates to a mining anchor mesh support device, specifically an adjustable mining anchor mesh support device. It belongs to the technical field of underground mine anchor support. Background Technology

[0002] With the continuous improvement of mechanization and automation in my country's metal and non-metal mines, a large number of rock bolt support devices have been widely used in mining operations. As mining depth increases, the safety risks caused by rock bursts and rock strata damage at the production face increase dramatically, placing increasingly higher demands on anchoring support. To ensure safe production at underground production faces, the current single rock bolt support method is insufficient. To enhance support quality and effectiveness, a hybrid support method combining rock bolts, anchor mesh, and shotcrete is often adopted.

[0003] When using a combination of anchor bolts and diamond-shaped anchor mesh for mixed support, the strong elasticity of the diamond-shaped mesh during mechanized anchoring operations can easily cause the mesh to curl up. Therefore, multiple people are usually required to work together to unfold the mesh, resulting in low work efficiency and high labor intensity during the anchoring process. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an adjustable diamond-shaped anchor net support device for mining, which has a bearing platform that is easy to adjust in size and support rods that are easy to adjust in spacing, so as to avoid the problem of curling during the lifting and installation of the anchor net and further improve the quality of anchor net support.

[0005] The technical solution of this utility model is as follows:

[0006] An adjustable diamond-shaped anchor mesh support device for mining includes a telescopic bearing platform and a support mechanism for connecting a lifting device and supporting the telescopic bearing platform from below. The telescopic bearing platform includes a rectangular frame composed of four L-shaped rectangular sleeves. The transverse tube of the inner L-shaped rectangular sleeve is telescopically fitted inside the transverse tube of the outer L-shaped rectangular sleeve, and the longitudinal tube of the inner L-shaped rectangular sleeve is telescopically fitted inside the longitudinal tube of the outer L-shaped rectangular sleeve. The support mechanism includes rectangular support tubes located below the longitudinal tubes on the two short sides of the rectangular frame. A lifting mechanism connecting tube running vertically is connected to the lower side of the rectangular support tube. Annular sliding support seats are installed on the telescopic bearing platform. There are several pairs of annular sliding support seats, each of which can be slidably installed on the transverse tubes. Two of each pair of annular sliding support seats are located on the two long sides of the rectangular frame. At least two pairs of annular sliding support seats each have an anchor mesh support rod installed, and the anchor mesh support rod passes through the same pair of annular sliding support seats and runs perpendicular to the axis of the transverse tube.

[0007] Preferably, the annular sliding support includes a sliding seat slidably mounted on the transverse tube and a circular sleeve fixed on the sliding seat and located above the transverse tube, with the anchor mesh support rod passing through the circular sleeve.

[0008] Preferably, a U-shaped sliding support is installed on the rectangular supporting square tube; the U-shaped sliding support includes a sliding plate seat fixedly installed on the rectangular supporting square tube and an inner and an outer vertical sliding plate fixed on the sliding plate seat; the two vertical sliding plates are arranged on the inner and outer sides of the longitudinal tube on their respective sides, and the upper end of the vertical sliding plate is higher than the upper side of the longitudinal tube on its respective side.

[0009] The beneficial effects of this utility model are as follows:

[0010] First, this invention allows for the adjustment of the supporting platform to the required specifications for each working face underground. The diamond mesh is suspended on the platform, and the support device is connected to the lifting device. The lifting device pre-transports the diamond mesh to the top of the support face and tightens it, effectively overcoming the shrinkage problem caused by the strong elasticity of the diamond anchor mesh during support. No manual assistance is required for mesh deployment. During diamond mesh drilling and anchor bolt support, no auxiliary personnel are needed, and multiple diamond meshes can be loaded, greatly improving the support efficiency. Multiple sets can be used in combination, and various lifting and support devices can be selected to match the available power sources on site, reducing the labor intensity of workers and completing the tightening of the entire cross-section in one operation, further improving operational efficiency.

[0011] Secondly, a sliding plate seat and an inner and outer vertical sliding plate are installed on the rectangular support tube of the support device. When the short side dimension of the rectangular frame is adjusted, the longitudinal tube can slide longitudinally along the inner wall of the vertical sliding plate. The setting of the support mechanism will not affect the size adjustment of the bearing platform. Attached Figure Description
