Description

Technical Field

[0001] The invention relates to the field of mine support, and specifically relates to a device for supporting a diamond net, and also relates to a method for supporting the diamond net. Background Art

[0002] Diamond mesh is a metal mesh that is easy to bend and deform. It has a flexible support effect when used to support the broken rocks on the roof. It can support the uneven rocks on the roof through its own deformation. Its support effect is better than that of rigid metal mesh, and it is particularly suitable for application on broken roofs.

[0003] Traditional diamond mesh support methods require workers to stand beneath the broken roof and use tools such as wooden planks to unfold and support the diamond mesh, ensuring it adheres to the roof rock. An anchor trolley is then used to install multiple anchors onto the roof. These anchors, coupled with anchor plates, secure the diamond mesh to the roof, allowing it to support a large area of ​​the roof rock.

[0004] However, the broken rock mass on the roof of an underground mine is extremely prone to roof collapse, and there are great safety risks for manpower working under the broken roof.

[0005] To address this issue, a foreign company has proposed a solution using a long-arm trolley and a manipulator to deploy and support the diamond mesh beneath the broken roof. During construction, the long-arm trolley and manipulator are used to fit the diamond mesh to the roof rock mass, followed by an anchor trolley to install multiple anchors and anchor plates onto the roof.

[0006] However, the rooftop rock crushing sites in underground mines do not allow for large open spaces, resulting in very narrow sites that often cannot accommodate both a long-arm trolley and an anchor trolley. Furthermore, manipulators also introduce new challenges, such as complex structures, high costs, and difficulty controlling them. Summary of the Invention

[0007] The present invention proposes a diamond mesh support device and method, the purpose of which is to solve the problems of large equipment size, high cost and difficult control in the existing mechanized diamond mesh support process.

[0016] As a further improvement of the diamond mesh support device: the frame body also includes a first connecting rod and a second connecting rod fixedly connected to the fixing seat, and an I-shaped frame fixed together with the first connecting rod and the second connecting rod.

[0017] As a further improvement of the diamond mesh support device: the right end of the first support rod is connected to the first hinge seat installed on the I-frame, and the right end of the second support rod is connected to the second hinge seat installed on the I-frame.

[0018] As a further improvement to the diamond mesh supporting device, the lower end of the first supporting spring and the lower end of the second supporting spring are both connected to the I-beam.

[0019] As a further improvement of the diamond mesh supporting device: the left end of the third support rod and the left end of the fourth support rod are both connected to the second rotating shaft installed on the I-frame.
