Description

Technical Field

[0001] This utility model relates to the field of slope protection, specifically a concrete spraying support mechanism for high slope protection. Background Technology

[0002] High slope protection concrete spraying is mainly suitable for easily weathered soft rock and rock excavation slopes with well-developed fissures and joints, uneven surfaces, and severe fractures. It can prevent further weathering of the slope surface and at the same time promote the filling of fractured rocks with mortar for reinforcement.

[0003] A patent application with application number 202021328980.5, entitled "An Auxiliary Support Device for Slope Spraying," includes a support frame, a rotating seat, and a sleeve. The support frame supports the rotating seat, which is horizontally rotatably connected to the top of the support frame. The sleeve is used to fix the spray nozzle and is rotatably connected to the rotating seat, and the sleeve can rotate relative to the rotating seat in a vertical plane. The auxiliary support device for slope spraying provided by this invention can fix the spray nozzle of a concrete spraying machine to the sleeve of the device during slope spraying. Through the horizontal rotation of the rotating seat and the rotation of the sleeve in a vertical plane, fixed-point spraying can be achieved.

[0004] However, when applying shotcrete to high slopes, the above method is difficult to apply to areas that are too high because the height cannot be adjusted. Furthermore, when applying shotcrete to areas that are too high, the distance of the shotcrete is too far, resulting in a significant waste of concrete. Utility Model Content

[0005] The purpose of this invention is to solve the above problems and provide a high slope protection concrete spraying support mechanism that can spray concrete on slopes of different heights, thereby improving efficiency.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A high slope protection concrete spraying support mechanism includes a lifting frame that moves up and down on the slope, a hoist installed on the slope for lifting the lifting frame, the hoist being connected to the lifting frame via a steel wire rope, a working platform on the lifting frame, and a connecting mechanism for connecting the spray nozzle on the working platform.

[0008] Furthermore, the bottom of the lifting frame is provided with a rotating shaft, and several support wheels are arranged side by side at both ends of the rotating shaft.

[0009] Furthermore, two steel wire ropes are arranged side by side.

[0010] Furthermore, the connecting mechanism includes a column mounted on the working platform, a turntable mounted on the column and rotating on the column, and a rotating shaft mounted on the turntable and rotating on the turntable, wherein a sleeve for fixing the nozzle is provided on the rotating shaft.

[0011] Furthermore, the turntable is provided with a mounting bracket, and both ends of the rotating shaft are rotatably connected to the mounting bracket.

[0012] Furthermore, the sleeve is provided with a locking screw.

[0013] Furthermore, the sleeve is provided with a handle.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model includes a lifting frame that moves up and down on a slope, and a hoist installed on the slope to lift the lifting frame. The hoist is connected to the lifting frame via a steel wire rope. A working platform is provided on the lifting frame, and a connecting mechanism for connecting the nozzle is provided on the working platform. When spraying concrete on the slope, the nozzle is installed on the working platform via the connecting mechanism. Then, the hoist lifts the lifting frame up and down on the slope, thereby completing the concrete spraying work. This allows for spraying concrete at different heights on high slopes. Attached Figure Description

[0016] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, for those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0017] Figure 1 This is a schematic diagram of the structure of this utility model.

[0018] In the diagram: 1. Lifting frame; 2. Hoist; 3. Wire rope; 4. Working platform; 5. Rotary shaft; 6. Support wheel; 7. Column; 8. Turntable; 9. Rotary shaft; 10. Sleeve; 11. Locking screw; 12. Handle. Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0020] like Figure 1 As shown, a high slope protection concrete spraying support mechanism includes a lifting frame 1 that moves up and down on the slope, and a hoist 2 installed on the slope for lifting the lifting frame 1. The hoist 2 is prior art and will not be described in detail here. The hoist 2 is connected to the lifting frame 1 via a steel wire rope 3. The lifting frame 1 is equipped with a working platform 4, and the working platform 4 is equipped with a connecting mechanism for connecting the nozzle. When spraying concrete on the slope, the nozzle is installed on the working platform 4 through the connecting mechanism. Then, the hoist 2 lifts the lifting frame 1 up and down on the slope, thereby completing the concrete spraying work. After the lifting frame 1 descends from the top to the bottom to complete the spraying work, the positions of the hoist 2 and the lifting frame 1 are moved to spray concrete on the other side.

[0021] The bottom of the lifting frame 1 is provided with a rotating shaft 5, and several support wheels 6 are arranged side by side at both ends of the rotating shaft 5. By arranging several support wheels 6 side by side, the lifting frame 1 will not sink into the pit when passing through the slope and unevenness, thus ensuring the smooth lifting of the lifting frame.

[0022] Two steel wire ropes 3 are arranged side by side. The lifting frame 1 is lifted by the two steel wire ropes 3. The lifting frame 1 is lifted smoothly. When the hoist 2 moves to a new position, it lifts the lifting frame 1 to the top. During this process, the force exerted on the lifting frame 1 by the two steel wire ropes is different, which will cause the lifting frame 1 to shift to one side of the unsprayed concrete position when it rises, thereby realizing the lateral displacement of the position of the lifting frame 1.

[0023] The connecting mechanism includes a column 7 mounted on the working platform 4, a turntable 8 mounted on the column 7 and rotating on the column 7, and a rotating shaft 9 mounted on the turntable 8 and rotating on the turntable 8. A sleeve 10 for fixing the nozzle is provided on the rotating shaft 9. When spraying concrete, the nozzle is passed through the sleeve 10 and fixed. Then, the angle of the turntable 8 is manually adjusted, and the sleeve 10 is moved up and down to complete the spraying of concrete onto the slope.

[0024] The turntable 8 is provided with a mounting bracket, and the two ends of the rotating shaft 9 are rotatably connected to the mounting bracket.

[0025] The sleeve 10 is provided with a locking screw 11 for fixing the nozzle.

[0026] The sleeve 10 is provided with a handle 12.
