When the first shaft rod rotates, it drives the two limit ratchets to rotate along the two limit pawls. When the two limit ratchets rotate along the two limit pawls, they both push the sliding sleeve through the transmission rod, causing the sliding sleeve to slide along the surface of the sliding rod and simultaneously pushing the spring. The spring can always push the limit pawl to engage with the limit ratchet through its own elastic force, so that the two limit ratchets can only rotate along the two limit pawls and cannot rotate against the two limit pawls, ensuring that the first gear will not reverse. When the first gear rotates, it drives the support tooth column to move outwards. When the support tooth column moves, it drives the positioning slider to slide along the inside of the positioning chute through the connecting block, increasing the stability when the support tooth column moves. When the support tooth column moves, it drives the support head to insert into the ground for support, thereby effectively supporting the foundation pit slope; enabling this support device to adapt to the slope according to the inclination of the foundation pit slope, making it match the inclination of the slope, and thus effectively supporting.

Detailed implementation mode

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Given by Figures 1 to 5 The present invention includes a support plate 1. Six drain pipes 2 for draining water from the slope are fixedly installed on the surface of the support plate 1. A first connector 3 is fixedly installed in the middle of one side of the support plate 1. A second connector 4 is rotatably installed on one side of the first connector 3. A support cylinder 5 is fixedly installed on the side of the second connector 4 away from the first connector 3. A support tooth column 6 is movably installed inside the support cylinder 5. A support head 7 is fixedly installed at one end of the support tooth column 6. A support adjustment assembly is provided on the upper side of the support cylinder 5. The support adjustment assembly is in transmission connection with the support tooth column 6. Rotating the support adjustment assembly can move the support tooth column 6 down to the ground for support; a connection block 8 is fixedly installed on the lower side of the support tooth column 6. A positioning slider 9 is fixedly installed at the bottom of the connection block 8. A positioning chute 10 is opened at the bottom inside the support cylinder 5. The positioning slider 9 is installed inside the positioning chute 10.

[0027] The operator presses the support plate 1 against the foundation pit slope and inserts the drain pipe 2 into the foundation pit slope to ensure the drainage effect of the foundation pit slope. Then, the operator drives the second connector 4 to rotate along the first connector 3 through the support cylinder 5, thereby adjusting the support angle of the support cylinder 5, so that while the support plate 1 adapts to the foundation pit slope, the required support angle can be adjusted. Immediately afterwards, the operator adjusts the support adjustment component to move the support tooth column 6 outwards. When the support tooth column 6 moves, it drives the positioning slider 9 to slide along the inside of the positioning chute 10 through the connecting block 8, increasing the stability of the support tooth column 6 when it moves. When the support tooth column 6 moves, it drives the support head 7 to insert into the ground for support, thereby effectively supporting the foundation pit slope; enabling this support device to adapt to the slope according to the inclination of the foundation pit slope, making it match the inclination of the slope, and thus effectively supporting it.

[0028] The support adjustment component includes an opening 11 and two first connecting frames 12. The opening 11 is opened at the end of the upper surface of the support cylinder 5. The first connecting frames 12 are fixedly installed at the ends on both sides of the support cylinder 5. First shaft sleeves 13 are fixedly installed at the upper parts in the middle of the two first connecting frames 12. A first shaft rod 14 is rotatably installed between the two first shaft sleeves 13; a first gear 15 is fixedly installed in the middle of the surface of the first shaft rod 14. The first gear 15 enters the inside of the support cylinder 5 through the opening 11 and is meshed and connected with the upper part of the support tooth column 6; a second gear 16 is meshed and connected to one side of the first gear 15. A second shaft rod 17 is fixedly installed in the middle of the second gear 16. Second shaft sleeves 18 are rotatably installed on both sides of the surface of the second shaft rod 17. A second connecting frame 19 is fixedly installed between the surfaces of the two second shaft sleeves 18. The bottom of the second connecting frame 19 is fixedly connected to the top of the support cylinder 5; a rotating rod 20 is fixedly installed at one end of the second shaft rod 17. A crank 21 is fixedly installed at the end of the rotating rod 20 away from the second shaft rod 17; limiting ratchets 22 are fixedly installed at both ends of the first shaft rod 14. Positioning rotating shafts 23 are fixedly installed at the lower parts on the mutually remote sides of the two first connecting frames 12. Limiting pawls 24 are rotatably installed at the ends of the positioning rotating shafts 23 away from the first connecting frames 12. The two limiting pawls 24 are engaged with the two limiting ratchets 22; transmission rods 25 are rotatably installed on one side of each of the limiting pawls 24. Slide sleeves 26 are rotatably installed at the ends of the transmission rods 25 away from the limiting pawls 24; sliding rods 27 are inserted into the inside of the slide sleeves 26. Fixed strips 29 are fixedly installed at both ends of the two sliding rods 27. One ends of the four fixed strips 29 are respectively fixedly connected to the mutually remote sides of the two first connecting frames 12; springs 28 are provided on the surfaces of the sliding rods 27. Both ends of the two springs 28 are respectively fixedly connected to the fixed strips 29 and the slide sleeves 26.

[0029] The operator drives the rotating rod 20 to rotate through the crank 21. When the rotating rod 20 rotates, it drives the second shaft rod 17 to rotate inside the two second bushings 18 on the second connecting frame 19. While the second shaft rod 17 rotates, it drives the first gear 15 to rotate through the second gear 16. When the first gear 15 rotates, it drives the first shaft rod 14 to rotate inside the two first bushings 13. When the first shaft rod 14 rotates, it drives the two limit ratchets 22 to rotate along the two limit pawls 24. When the two limit ratchets 22 rotate along the two limit pawls 24, they both push the sliding sleeve 26 through the transmission rod 25, causing the sliding sleeve 26 to slide along the surface of the sliding rod 27 and simultaneously pushing the spring 28. The spring 28 can always push the limit pawl 24 to engage with the limit ratchet 22 through its own elastic force, so that the two limit ratchets 22 can only rotate along the two limit pawls 24 and cannot rotate against the two limit pawls 24, ensuring that the first gear 15 will not reverse. When the first gear 15 rotates, it drives the support tooth column 6 to move outwards and support on the ground.
