[0003] For example, Chinese utility model CN221422001U specifically relates to a rock and soil collapse protection device for use along roads. The drill bit can be inserted into the ground during rotation, so that the base plate can be installed on the ground more conveniently, and the angle of the support plate can be adjusted by adjusting the position of the movable frame and the position of the support plate on the limit frame, so that the angle adjustment freedom of the support plate can be more diverse.

[0004] However, the existing protective device is only fixed by a drill bit at one end of the base plate, and its overall stability is poor during actual use; and, the support plate is supported by a limit frame, which makes the angle adjustment of the support plate not flexible enough, and the protection angle it adapts to is limited, resulting in poor overall flexibility and adaptability.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1

[0036] See also Figures 1 to 4 As shown, the present invention is a road collapse protection device, comprising a base plate 1, one end of which is hinged with a protection baffle 2. The base plate 1 is rotatably connected to a screw rod 101, two transmission rods 102 and four shaft sleeves 3 through a bearing bracket, and is slidably connected to a sliding seat 103 through a guide rail slider assembly.

[0037] The sliding seat 103 cooperates with the screw rod 101 through a nut, and the sliding seat 103 and the protective baffle 2 are hingedly connected by two or more support rods 104, which are used to rotate the screw rod 101 so that the screw rod 101 drives the sliding seat 103 to move. During the movement of the sliding seat 103, the support rod 104 is used to drive the protective baffle 2 to rotate, so that the angle of the protective baffle 2 can be flexibly adjusted, which is convenient for adapting to support and protection at various angles, and effectively improves the overall adaptability and flexibility of use.

[0038] The four sleeves 3 are evenly distributed on one side of the two transmission rods 102, that is, the four sleeves 3 are distributed in a rectangular shape, and two sleeves 3 are paired with one, the sleeves 3 are connected to the auger rod 301, the outer wall of the sleeves 3 is fixedly connected to the driven wheel 302, the transmission rod 102 is fixedly connected to the driving wheel 303 which is connected to the driven wheel 302 one by one, and is used to drive the sleeves 3 to rotate through the transmission rod 102, and use the auger rod 301 to drill into the ground to achieve anchoring.

[0039] like Figure 6 and 8 As shown, the sleeve 3 is a spline shaft structure, and the auger rod 301 has a spline shaft structure matched with the sleeve 3, so that when the sleeve 3 drives the auger rod 301 to rotate, the auger rod 301 can move axially during the rotation process, so that the auger rod 301 can be drilled into the ground for anchoring, and the auger rod 301 and the sleeve 3 can be flexibly disassembled and assembled, which is convenient for transportation and storage. In addition, the axial direction of the sleeve 3 is inclined, and the lower end of the auger rod 301 is inclined toward the side away from the protective baffle 2.

[0040] The driving wheel 303 and the driven wheel 302 are mutually meshing helical gears. The bottom plate 1 is provided with four oblique holes 105, and the upper surface of the bottom plate 1 is fixedly connected with a shaft seat 106 corresponding to the oblique holes 105; the shaft seat 106 is coaxially arranged with the oblique holes 105, and the shaft sleeve 3 is rotatably connected with the shaft seat 106.

[0041] By opening the inclined hole 105 and the rotational connection between the sleeve 3 and the shaft seat 106, the auger rod 301 is arranged to be inclined after cooperation with the sleeve 3, so that the auger rod 301 is inclined to drill into the ground, which not only improves the fixing effect of the base plate 1 in the horizontal direction, but also greatly improves the fixing of the base plate 1 in the vertical direction, thereby improving the overall fixing effect and ensuring stability during the protection process.

[0042] In addition, if Figure 1 , 4 As shown in Figures 5 and 6, the bottom plate 1 is rotatably connected to the rotating rod 4, and the rotating rod 4 is connected to the hand wheel 401. The two transmission rods 102 are both transmission-connected to the rotating rod 4, such as the transmission between the transmission rod 102 and the rotating rod 4 through a sprocket and chain or a synchronous wheel and a synchronous belt, so that the two transmission rods 102 are synchronously driven to rotate through the rotating rod 4, and the driving wheel 303 is engaged with the driven wheel 302 to synchronously drive the four shaft sleeves 3 to rotate, and then the four spiral drill rods 301 are synchronously drilled into the ground for anchoring, thereby improving the convenience of use.

[0043] In addition, the rotating rod 4 is a tubular structure, and is internally rotatably connected to a connecting shaft 402. One end of the connecting shaft 402 is connected to the screw rod 101 via a coupling, and the other end extends out of the rotating rod 4 and is connected to a crank 403. The screw rod 101 is connected to the connecting shaft 402 inserted into the rotating rod 4, so that the crank 403 and the handwheel 401 are located at the same end of the rotating rod 4, which not only helps to improve the convenience of operation, but also makes the overall structure more compact.

[0044] Embodiment 2

[0045] Based on the first embodiment, Figure 1 , 5 As shown in FIG. 9 , two anchor rods 5 are also included. One end of the anchor rod 5 is connected to a spiral sheet 501, and the other end is fixedly connected to a limit block 502. The end surface of the limit block 502 is provided with a hexagonal hole, or the limit block 502 is a hexagonal column structure, which is convenient for rotating the anchor rod 5. The protective baffle 2 is provided with two stepped holes 201. The stepped holes 201 are provided with internal threads and are threadedly connected to a block 202. The end surface of the block 202 is provided with a hexagonal hole.

[0046] like Figure 7 As shown, after the protective baffle 2 is adjusted, the anchor rod 5 is drilled into the foundation position through the stepped hole 201, wherein the outer diameter of the spiral piece 501 is smaller than the inner diameter of the stepped hole 201, the diameter of the limit block 502 is larger than the smaller aperture in the stepped hole 201, and smaller than the larger aperture, the anchor rod 5 rotates, and the rotating member is screwed into the foundation through the action of the spiral piece 501, and when the limit block 502 abuts against the stepped surface in the stepped hole 201, the blocking block 202 is screwed into the stepped hole 201, and the blocking block 202 abuts against the limiting block 502, and the blocking block 202 is locked, thereby realizing the position limitation of the anchor rod 5. Adding the anchor rod 5 can further improve the protection effect against road collapse.

[0047] In combination with the above-mentioned embodiment, the construction method of the road collapse protection device includes placing the protection device to the installation position. Before the protection device is placed on the ground, the upper ends of the four spiral drill rods 301 are inserted into the sleeve 3 through the inclined hole 105 of the base plate 1, and then the base plate 1 is placed on the ground. At this time, the lower ends of the four spiral drill rods 301 are pressed against the ground.

[0048] The rotating rod 4 is rotated by the hand wheel 401, and the rotating rod 4 drives the two transmission rods 102 to rotate at the same time. The transmission rod 102 drives the sleeve 3 to rotate through the driving wheel 303 and the driven wheel 302, so that the four spiral drill rods 301 rotate synchronously, and the spiral drill rods 301 are used to drill into the ground to fix the position of the base plate 1.

[0049] After the position of the base plate 1 is fixed, the screw rod 101 is rotated by the crank 403, and the sliding seat 103 is moved, and the support rod 104 is used to drive the protective baffle 2 to rotate, so that the angle of the protective baffle 2 is adjusted, and the protective baffle 2 is placed close to the position of the foundation that needs to be protected, so as to use the protective baffle 2 for protection and prevent road collapse.

[0050] In addition, the anchor rod 5 is drilled into the foundation position through the stepped hole 201, and then screwed into the stepped hole 201 through the blocking block 202. The blocking block 202 abuts against the limit block 502, and the blocking block 202 is locked to limit the position of the anchor rod 5. The anchoring effect of the anchor rod 5 is utilized to further improve the protection of the road and effectively improve the overall anti-collapse effect.
