[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 and Figure 2 This utility model discloses a retaining device for mine slope treatment, comprising a base plate 1, at least four mounting openings 11, a rotating frame 21 rotatably mounted on one side of the mounting opening 11, a movable wheel 22 rotatably mounted on the rotating frame 21, a wheel-retracting hydraulic cylinder 23 hinged between the base plate 1 and the rotating frame 21, the wheel-retracting hydraulic cylinder 23 being a self-locking hydraulic cylinder, a retaining plate 3 hinged to one side of the base plate 1, a supporting hydraulic cylinder 41 hinged between the base plate 1 and the retaining plate 3, the supporting hydraulic cylinder 41 being a self-locking hydraulic cylinder, and a plurality of supporting holes 51 evenly provided on the base plate 1, a supporting rod 52 slidably mounted in the supporting holes 51.

[0029] Specifically, a retaining wall structure is formed by setting up a base plate 1 and a hinged retaining plate 3, and a supporting hydraulic cylinder 41 is installed between the base plate 1 and the retaining plate 3 as a support. Moving wheels 22 are set at the bottom of the base plate 1, and the moving wheels 22 can be retracted by a retraction hydraulic cylinder 23.

[0030] In this way, a temporary retaining structure is formed by setting up a base plate 1, a retaining plate 3 and a supporting hydraulic cylinder 41. A retractable moving wheel 22 is set at the bottom of the base plate 1 to facilitate movement and avoid damage to the moving wheel 22 when the retaining structure is formed.

[0031] In some feasible configurations, both the base plate 1 and the retaining plate 3 are rectangular plates, the mounting opening 11 is rectangular, the rotating frame 21 includes a mounting plate hinged to the mounting opening 11, a support plate is fixedly mounted on the upper side of the rectangular opening, the first end of the retracting wheel hydraulic cylinder 23 is hinged to the upper end of the mounting plate, and the second end is hinged to the upper end of the support plate. The supporting hydraulic cylinder 41 is installed in the middle of the base plate 1 and the retaining plate 3. To facilitate better support, the supporting rod 52 is installed at an angle, with the angle pointing away from the retaining plate 3. The supporting rod 52 is nail-shaped. After the positions of the base plate 1 and the retaining plate 3 are adjusted, a hole is drilled in the ground within the supporting hole 51 using drilling equipment, and the supporting rod 52 is inserted.

[0032] In some feasible configurations, the supporting hydraulic cylinder 41 and the retracting wheel hydraulic cylinder 23 require power from a hydraulic station. This hydraulic station can be an independent unit mounted on the base plate 1, or it can be connected to the hydraulic stations of other equipment via pipelines. In practical applications, multiple retaining devices may be used to cover long slopes, and a separate hydraulic station can be installed to power multiple retaining devices. The configuration of the hydraulic station and hydraulic cylinders is a common existing technology and will not be elaborated upon here. The supporting hydraulic cylinder 41 and the retracting wheel hydraulic cylinder 23 are configured as self-locking hydraulic cylinders to maintain their position after the power supply is disconnected.

[0033] As a specific embodiment of a retaining device for mine slope treatment provided in the application, the base plate 1 is hinged to two support screw tubes 421 with internal threads, the support screw tubes 421 are threaded to support screw rods 422, the retaining plate 3 is fixedly installed with support blocks 423, and the support screw rods 422 are adjusted to abut against the support blocks 423.

[0034] Overall, during use, the hydraulic cylinder 41 of the retaining plate 3 supports the slope. After the support screw 421 and support screw 422 are installed, the hydraulic cylinder 41 completes the support. Then, the support screw 422 is screwed out to abut against the support block 423 for auxiliary support. This reduces the continuous stress on the hydraulic cylinder 41, improves its service life, and reduces the possibility of the hydraulic cylinder 41 failing, causing the retaining plate 3 to lose support.

[0035] Furthermore, a connecting rod 424 is slidably installed inside the support screw 422, and the support screw 422 and the connecting rod 424 are rotatably connected, with the end of the connecting rod 424 hinged to the support block 423.

[0036] It should be understood that by setting the linkage rod 424, when the supporting hydraulic cylinder 41 supports the retaining plate 3, the linkage rod 424 drives the supporting screw 422 to lift synchronously, reducing the work of adjusting the supporting screw 422. After the supporting hydraulic cylinder 41 completes the support, the supporting screw 422 can be unscrewed.

[0037] In some feasible embodiments, the support screw 421 is a round tube with internal threads, the support screw 422 is a round tube with external threads, and the connecting rod 424 is slidably inserted into the support screw 422. A handwheel is installed at the upper end of the support screw 422 for easy rotation.

[0038] As another specific embodiment of a retaining device for mine slope treatment provided in the application, a heel plate 31 is hinged to the side of the base plate 1 near the retaining plate 3.

[0039] Based on specific application scenarios, by setting up a heel plate 31, the heel plate 31 is extended during use, and the slope filler is covered on the heel plate 31. The heel plate 31 exerts downward pressure on the entire device, thereby improving the support stability of the retaining plate 3.

[0040] In some feasible embodiments, the heel plate 31 is rectangular. To facilitate its storage and use, a connector 32 is provided on the side of the heel plate 31 away from the retaining plate 3. The connector 32 detachably connects the heel plate 31 and the retaining plate 3. The connector 32 is C-shaped, with an opening on the side of the heel plate 31. The connector 32 is rotatably inserted into the opening, and the other end of the connector 32 is engaged with the side of the retaining plate 3.

[0041] As a specific embodiment of a retaining device for mine slope treatment provided in the application, the retaining plate 3 is provided with a connecting plate 6 and a threaded hole for matching bolts on both sides, and the connecting plate 6 is also provided with a threaded hole on the side away from the retaining plate 3.

[0042] Depending on the specific application scenario, multiple retaining devices are required on long slopes. By setting up connecting plates 6, it is easy to form connections between adjacent retaining devices, thereby improving the overall stability.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
