A spring leaf 10 is arranged in the rotating sleeve 9, and one active end of the spring leaf 10 is fixed on the inner wall of the rotating sleeve 9, and the other active end is fixed on the fixed shaft 8. Two steel wire ropes 11 are symmetrically arranged on the outer wall of the rotating sleeve 9. A fixed plate 12 is installed on the side of the support block 3, and the other ends of the two steel wire ropes 11 are sequentially wound around the guide shaft 6 on the upper side of the support block 3 and the guide shaft 6 on the lower side of the support block 3 and connected under the fixed plate 12. Baffles 13 are evenly arranged on the steel wire ropes 11, and two threading holes 14 are symmetrically opened at both ends of the baffle 13, and the two steel wire ropes 11 respectively pass through the two threading holes 14 set at both ends of the baffle 13.

[0024] The No. 1 hydraulic telescopic rod 2 is horizontally arranged, the support block 3 and the mounting block 1 are located in the same horizontal plane, the No. 2 hydraulic telescopic rod 4 and the No. 1 hydraulic telescopic rod 2 are perpendicular to each other, the guide shaft 6 and the No. 2 hydraulic telescopic rod 4 are perpendicular to each other, and the guide shaft 6 is located between the two No. 2 hydraulic telescopic rods 4, the fixed shaft 8 and the guide shaft 6 are parallel to each other, and the fixed shell 7 is located on the No. 1 hydraulic telescopic rod 2, the rotating sleeve 9 is rotatably arranged in the fixed shell 7, the fixed shell 7 is located between the support block 3 and the mounting block 1, the baffle 13 and the guide shaft 6 are parallel to each other, and the evenly arranged baffles 13 are parallel to each other, and the baffle 13 can be wound around the outside of the rotating sleeve 9 through the wire rope 11 and is located in the fixed shell 7.

[0025] Annular grooves 17 are symmetrically provided at both ends of the guide shaft 6, and limit blocks 15 are symmetrically installed on the side surfaces of both ends of the baffle 13.

[0026] During operation, since the size of the support plates of the existing water conservancy project construction channel side wall support device is fixed, the size of the support area cannot be adjusted according to the usage, resulting in poor applicability. In the present scheme, in the initial state, the spring 10 will always twist the rotating sleeve 9, so that the baffle 13 can be rolled up on the rotating sleeve 9 through the rotating sleeve 9 and the wire rope 11, and located in the fixed shell 7. When in use, the device is placed in the channel, and then the No. 1 hydraulic telescopic rod 2 in the extension support assembly on both sides of the mounting block 1 is controlled to extend at the same time. When the No. 1 hydraulic telescopic rod 2 is extended, it will drive the support block 3 and the components thereon to move to both sides at the same time, and the No. 1 hydraulic telescopic rod 2 is used to make the side surfaces of the baffles 13 located on both sides of the mounting block 1 fit against the inner walls on both sides of the channel. The baffles 13 evenly arranged on both sides of the mounting block 1 support the inner walls on both sides of the channel, so as to achieve the function of supporting the inner wall of the channel. When it is necessary to expand the supporting surface, the No. 2 hydraulic telescopic rod 4 on the upper and lower sides of the support block 3 is controlled to extend at the same time. When extended, the guide shafts 6 located on the upper and lower sides of the support block 3 will expand outward at the same time, thereby increasing the distance between the two guide shafts 6. As the distance between the two guide shafts 6 increases, the length of the wire rope 11 between the two guide shafts 6 will also increase, and as the guide shaft 6 drives the wire rope 11 to extend in length, the baffle 13 wound on the outside of the rotating sleeve 9 will be brought out of the fixed shell 7 through the wire rope 11, thereby increasing the number of baffles 13 between the two guide shafts 6. When the number of baffles 13 located on the side of the guide shaft 6 increases, the support area of ​​the evenly arranged baffles 13 will also increase. When it is necessary to reduce the support area, the second hydraulic telescopic rod 4 located on both sides of the support block 3 is controlled to contract. When the distance between the two guide shafts 6 is reduced, the length of the wire rope 11 will also be shortened, and under the action of the spring 10, the excess baffles 13 can be reeled into the fixed shell 7 through the wire rope 11, and the support area is adjusted.

[0028] When working, the existing support device is not convenient to move on soft ground. When in use, the rollers under the base will sink into the mud, causing the device to tilt. In this solution, the support device is driven to move by the track drive mechanism 20, and the support area of ​​the track drive mechanism 20 is used to improve the convenience of movement. The cooperation achieves the effect of stable driving and realizes the effect of being able to move on soft ground.

[0029] Working principle: In the initial state, the spring 10 will always twist the rotating sleeve 9 so that the baffle 13 can be rolled up on the rotating sleeve 9 through the rotating sleeve 9 and the wire rope 11, and located in the fixed shell 7. When in use, the device is placed in the channel, and then the No. 1 hydraulic telescopic rod 2 in the extension support assembly on both sides of the mounting block 1 is controlled to extend at the same time. When the No. 1 hydraulic telescopic rod 2 is extended, it will drive the support block 3 and the components thereon to move to both sides at the same time, and the baffles 13 located on both sides of the mounting block 1 are fitted to the inner walls on both sides of the channel through the No. 1 hydraulic telescopic rod 2. The baffles 13 evenly arranged on both sides of the mounting block 1 support the inner walls on both sides of the channel to achieve the function of supporting the inner wall of the channel. When it is necessary to expand the supporting surface, the No. 2 hydraulic telescopic rod 4 on the upper and lower sides of the support block 3 is controlled to extend at the same time. When the No. 2 hydraulic telescopic rod 4 on the upper and lower sides of the support block 3 is extended, the guide shaft 6 located on the upper and lower sides of the support block 3 will be expanded outward at the same time, thereby achieving the effect of supporting the inner wall of the channel. The spacing between the two guide shafts 6 is increased, and as the spacing between the two guide shafts 6 increases, the length of the wire rope 11 between the two guide shafts 6 will also increase, and as the guide shaft 6 drives the wire rope 11 to extend in length, the baffle 13 wound on the outside of the rotating sleeve 9 will be brought out of the fixed shell 7 through the wire rope 11, thereby increasing the number of baffles 13 between the two guide shafts 6. When the number of baffles 13 located on the side of the guide shaft 6 increases, the support area of ​​the evenly arranged baffles 13 will also increase. When it is necessary to reduce the support area, the No. 2 hydraulic telescopic rod 4 located on both sides of the support block 3 is controlled to contract. When the spacing between the two guide shafts 6 is reduced, the length of the wire rope 11 will also be shortened, and under the action of the spring leaf 10, the excess baffles 13 can be reeled into the fixed shell 7 through the wire rope 11, and the support area is adjusted. Compared with the traditional channel side wall support device for water conservancy project construction, it has better applicability and is more convenient to use.

[0030] The support device is driven to move by the crawler drive mechanism 20, and the convenience of movement is improved by the support area of ​​the crawler drive mechanism 20, which achieves the effect of stable driving and realizes the effect of being able to move on soft ground.
