Description

Technical Field

[0001] The present invention relates to the technical field of tunnel support, and in particular to a support device for tunnel excavation in water conservancy projects. Background Technique

[0002] In water conservancy projects, in order to convey water or discharge flood, closed water conveyance channels are often excavated through mountains, which are called hydraulic tunnels. In order to avoid collapses during the process of tunnel excavation, support devices are needed to support the tunnels.

[0003] Among them, the existing arch frame structure is relatively simple. After a long time of support by its single-layer structure, relatively large pressure may easily cause the structure to deform, affecting the support effect. At the same time, the support device does not have an adjustment function, so that the support device cannot adjust the support height according to the height of the tunnel, resulting in limitations in support, so there are defects that are not convenient for support adjustment and use, and thus cannot meet the usage requirements of customers.

[0004] Therefore, those skilled in the art have provided a support device for tunnel excavation in water conservancy projects to solve the problems raised in the above background technique. Summary of the Invention

[0005] In order to improve the problem of inconvenient support adjustment and use, the present invention provides a support device for tunnel excavation in water conservancy projects.

[0007] A support device for tunnel excavation in water conservancy projects includes a concave plate. A rotating cylinder is embedded at the top of the concave plate. The outer surface of the rotating cylinder is rotationally connected to the connection part of the concave plate through a bearing. A stud is threadedly connected to the inner surface of the rotating cylinder. The top of the stud penetrates through the rotating cylinder and is fixedly connected to a lifting plate. Springs are uniformly fixedly connected to the top of the lifting plate. The top of the springs is fixedly connected to an arc-shaped support plate. Positioning cylinders are embedded at the four corners of the top of the lifting plate and inside the springs. A sliding plate is slidably connected to the inner surface of the positioning cylinder.

[0012] By adopting the above technical solutions, the setting of the locking plate can limit the universal wheel.

[0013] Optionally, the bottom of the support cylinder is fixedly connected with a chassis, and the number of the chassis is four.

[0014] By adopting the above technical solutions, the setting of the chassis can increase the support area of the support cylinder and improve the stability of the support placement.

[0015] Optionally, sliding grooves for cooperating with the sliding plate are respectively arranged on the left and right sides of the inner cavity of the positioning cylinder, and the outer surface of the sliding plate is slidably connected with the inner surface of the sliding groove.

[0016] By adopting the above technical solutions, the setting of the sliding groove can guide and limit the sliding plate.
