Description

Technical Field

[0001] This utility model belongs to the field of slope protection technology, specifically relating to a precast slope protection block handling device. Background Technology

[0002] Precast slope protection blocks are concrete or reinforced concrete components that are prefabricated in a factory and laid on the surface of channel slopes to form a strong and durable protective layer that resists water erosion, prevents slope erosion, and enhances slope stability.

[0003] However, in actual construction, due to the steep slopes of the channels and the presence of multiple slopes in some construction areas, the transportation of precast slope protection blocks largely relies on manual handling or crane lifting. This is especially problematic on steep slopes where specialized machinery is lacking. Manual handling of precast slope protection blocks presents the following issues: 1. High safety risks: Handling heavy objects on slopes increases the risk of slipping and falling; 2. Low construction efficiency: Manual handling is slow, labor-intensive, and affects the overall construction progress. While some projects use cranes or excavators for assisted handling, these are costly, inflexible, and unsuitable for multi-level slopes or narrow construction sites. Utility Model Content

[0004] To address the aforementioned problems, embodiments of this utility model propose a precast slope protection block handling device.

[0005] This utility model discloses a precast slope protection block handling device, comprising: a winch mounted on a winch platform located on a road surface above the slope; a track consisting of two parallel channel steels, positioned on the slope and connected at their top ends to the winch platform; rigid wheels that engage with the track; a base plate connected to the rigid wheels via bearings at its bottom; an angle adjustment assembly mounted on the base plate; a guard plate connected to the base plate via the angle adjustment assembly; an anti-slip rubber pad horizontally positioned on the angle adjustment assembly; and multiple steel wire ropes, one end of which is connected to the ends of the guard plate and the base plate, and the other end passing through a steel wire rope lock and connected to the winch.

[0006] The channel steel is replaced with I-beams or aluminum alloy rails.

[0007] The winch platform is also equipped with a counterweight and a wire rope guide roller. The counterweight is located on the side of the winch platform away from the track, and the wire rope guide roller is located between the track and the winch.

[0008] The wire rope guide roller is mounted on a height-adjustable bracket, which can be a hydraulic rod or an electric telescopic rod.

[0009] The rigid wheel includes a steel roller with an arc-shaped side and a steel ring fixedly fitted in the middle of the outer side of the steel roller. The outer surface of the steel ring is engraved with anti-slip patterns.

[0010] The angle adjustment component includes U-shaped fixing grooves arranged parallel to both sides of the base plate. One end of the fixing groove is connected to a rotating rod via a rotating shaft, and the other end is connected to a limiting groove via a rotating shaft.

[0011] The limiting groove is also a channel steel, and there are two limiting grooves. Each limiting groove is connected to a fixed groove. The width of the limiting groove is smaller than the width of the fixed groove. The bottom surface of the limiting groove is fixedly connected to the guard plate. A hanging hole is provided on each of the two sides of the top of the guard plate.

[0012] There are four rotating rods, with two rotating rods in a group located on both sides of a fixed groove, and both ends of the two rotating rods are connected by a rotating shaft. Multiple limiting holes are provided at intervals along the length direction on the limiting groove, and the depth and width of the limiting holes are both greater than the diameter of the rotating shaft connecting the rotating rods.

[0014] Rubber limit blocks and locking bolts are installed at both ends of the track.

[0015] The beneficial effects of this utility model are as follows: the slope protection precast block handling device of this utility model can adjust the angle between the anti-slip rubber pad and the slope by setting an angle adjustment component, so that the anti-slip rubber pad is kept in a horizontal state, thereby making the slope protection precast block handling device of this application applicable to slopes with different angles and having a wider range of applications; the edge of the rigid wheel of this application is arc-shaped, which can better match the track and reduce friction between the wheel and the track; the rubber limit block and locking bolt are set in the track to effectively prevent the rigid wheel from derailing.

[0022] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] like Figures 1-4 As shown, the precast slope protection block handling device of this utility model includes: a winch 3, a track 9, rigid wheels 7, a base plate 11, an angle adjustment assembly, a guard plate 6, an anti-slip rubber pad 8, and a wire rope. The winch 3 is mounted on a winch platform 1, which is located on the road surface above the slope. A counterweight 2 and a wire rope guide roller 4 are also installed on the winch platform 1. The counterweight 2 is located on the side of the winch platform 1 away from the track 9, and the wire rope guide roller 4 is located between the track 9 and the winch 3. The wire rope guide roller 4 is mounted on a height-adjustable bracket 10, which is a hydraulic rod or an electric telescopic rod. The height of the wire rope guide roller 4 can be adjusted by adjusting the height-adjustable bracket 10 to match the height of the winch 3. After passing through the guard plate 6 and the base plate 11, the wire rope is gathered together by the wire rope lock 5, then passes around the wire rope guide roller 4, and finally connects to the winch 3. The winch 3 rotates to drive the base plate 11 and the guard plate 6 to move along the track 9, thereby transporting the precast blocks to the corresponding positions.

[0024] The track 9 consists of two parallel channel steels, which can be replaced with I-beams or aluminum alloy tracks. The track 9 is installed on the slope and its top end is connected to the winch platform 1. Both ends of the track 9 are equipped with rubber limit blocks 17 and locking bolts 16. The rubber limit blocks 17 prevent the rigid wheels 7 from derailing, and the locking bolts 16, combined with the rubber limit blocks 17, enable rapid fixing and precise positioning of the track 9.

[0025] A support frame can also be installed at the bottom of track 9. The support frame consists of telescopic rods and is used to adjust the height and position of track 9.

[0026] The rigid wheel 7 is engaged with the track 9, meaning that the rigid wheel 7 can move inside the track 9.

[0027] The rigid wheel 7 includes a steel roller 18 with an arc-shaped edge 19 on its side. The arc-shaped edge 19 prevents the rigid wheel 7 from colliding with the inner wall of the track 9, reduces friction between the rigid wheel 7 and the inner wall of the track 9, and allows the rigid wheel 7 to roll smoothly inside the track 9. A steel ring 20 is fixedly fitted around the outer center of the steel roller 18, and the outer surface of the steel ring 20 is engraved with anti-slip texture. The width of the steel ring 20 is smaller than the width of the steel roller 18.

[0028] A base plate 11 is provided on the top of the rigid wheel 7. Specifically, the bottom ends of the base plate 11 are connected to the rigid wheel 7 through bearings, that is, the movement of the rigid wheel 7 can drive the base plate 11 to move.

[0029] An angle adjustment assembly is mounted on the base plate 11, and the guard plate 6 is connected to the base plate 11 via the angle adjustment assembly. The anti-slip rubber pad 8 is horizontally mounted on the angle adjustment assembly. The angle adjustment assembly has a triangular connection structure, with the base plate 11, guard plate 6, and anti-slip rubber pad 8 mounted on three sides of the assembly, thus forming a triangular structure between them. The base plate 11 is positioned along the track 9, the anti-slip rubber pad 8 is positioned horizontally, and the guard plate 6 is positioned vertically.

[0030] The angle adjustment assembly includes U-shaped fixing grooves 15 arranged parallel to both sides of the base plate 11. The fixing grooves 15 can be channel steel. One end of the fixing groove 15 is connected to the rotating rod 14 through a rotating shaft, and the other end is connected to the limiting groove 12 through a rotating shaft. The two fixing grooves 15 are arranged parallel to each other with the two tracks 9.

[0031] The limiting groove 12 is also a channel steel. There are two limiting grooves 12, and each limiting groove 12 is connected to a fixed groove 15. The width of the limiting groove 12 is smaller than the width of the fixed groove 15. That is to say, when the limiting groove 12 rotates between the fixed groove 15 and the fixed groove 15, the bottom of the limiting groove 12 can be inserted into the fixed groove 15.

[0032] The bottom surface of the limiting groove 12 is fixedly connected to the guard plate 6. When the limiting groove 12 rotates relative to the fixed groove 15, it will drive the guard plate 6 to rotate relative to the base plate 11.

[0033] There are four rotating rods 14. Two rotating rods 14 are located on both sides of a fixed groove 15, and both ends of the two rotating rods 14 are connected by a rotating shaft. That is to say, the rotating rods 14 rotate relative to the fixed groove 15 through the rotating shaft.

[0034] A patterned steel plate is fixedly connected to the upper surface of the rotating rod 14, and an anti-slip rubber pad 8 is provided on the upper surface of the patterned steel plate. When the rotating rod 14 rotates, it can drive the patterned steel plate and the anti-slip rubber pad 8 to rotate accordingly.

[0035] Multiple limiting holes 13 are spaced apart along the length of the limiting groove 12. The depth and width of the limiting holes 13 are both greater than the diameter of the shaft connecting the rotating rod 14. Therefore, the end of the rotating rod 14 can be inserted into the limiting hole 13 of the limiting groove 12. The end of the limiting hole 13 away from the opening is a downwardly recessed arc-shaped groove. Because the position of the arc-shaped groove is lower than the position of the opening, the rotating rod 14 will stay in the downwardly recessed arc-shaped groove after being inserted into the limiting hole 13 and will not easily come out. By inserting the rotating rod 14 into the limiting holes 13 at different heights, the height and angle of the patterned steel plate and the anti-slip rubber pad 8 can be adjusted, thereby adapting to slope protection at different angles.

[0036] A hanging hole is provided on each of the two sides of the top of the guard plate 6, and a hanging hole is also provided on each of the two sides of the top of the base plate 11. There are multiple wire ropes, one end of which is connected to the hanging holes on the guard plate 6 and the base plate 11 respectively, and the other end of which passes through the wire rope lock 5 to form a bundle. The wire rope in the winch 3 is also connected to the wire rope lock 5 after passing around the wire rope guide roller 4.

[0037] The wire rope connecting the hanging hole on the guard plate 6 and the base plate 11 and the wire rope lock 5 can be replaced with a steel pipe. Then, a hole is opened at the end of the steel pipe, and the wire rope is connected to the winch 3.

[0038] In use, this invention first inserts the rotating rod 14 into the corresponding limiting hole 13 according to the slope angle, so that the patterned steel plate and the anti-slip rubber pad 8 are in a horizontal position. Then, one end of the wire rope is connected to the hanging holes on the base plate 11 and the guard plate 6 respectively, and then bundled together through the wire rope lock 5. The other end of the wire rope is passed around the wire rope guide roller 4 and finally connected to the winch 3. After the device is connected, the precast slabs are stacked on the anti-slip rubber pad 8, and finally the winch 3 is started to transport the precast slabs to the corresponding position.

[0039] Although the above embodiments have been shown and described, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Any changes, modifications, substitutions and variations made to the above embodiments by those skilled in the art are within the protection scope of the present invention.
