DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0026] like Figure 1 and Figure 2 As shown, a supporting tool for shaft excavation includes: a load-bearing frame 20, a rectangular groove is opened at the bottom of the load-bearing frame 20, a cylinder 22 is arranged in the rectangular groove of the load-bearing frame 20, and the cylinder 22 is composed of a main body and an extension end, and the extension end can be extended on the wall surface of the main body. This is an existing technology, so it will not be described here.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a folding structure can facilitate the use and storage of the device. The folding structure includes: a support frame 21 and a straight rod 34. The support frame 21 is symmetrically rotatably connected in a rectangular groove of the load-bearing frame 20. The straight rod 34 is slidably connected to the top of the symmetrical straight rod 34. The support frame 21 can be flipped from the bottom of the load-bearing frame 20. A groove for adapting the cylinder 22 is provided at the bottom of the support frame 21. The cylinder 22 is fixedly connected in the groove on the wall of the support frame 21.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, the symmetrical support frame 21 can be stored in the rectangular groove at the bottom of the load-bearing frame 20, and the two ends of the straight rod 34 are slidably connected to the top of the support frame 21. The length of the straight rod 34 is consistent with the rectangular groove of the load-bearing frame 20. The folding structure also includes a slide plate 30, a transverse groove 31, a vertical groove 32 and a slide column 33. The slide plate 30 is symmetrically fixedly connected at the top of the support frame 21. The transverse groove 31 runs through the wall surface of the slide plate 30, and the vertical groove 32 also runs through the wall surface of the slide plate 30. The slide column 33 is slidably connected in the transverse groove 31, and the top of the slide column 33 is also fixedly connected to the bottom of the straight rod 34. The transverse groove 31 and the vertical groove 32 can form an L-shaped groove. The transverse groove 31 and the vertical groove 32 can adapt to the diameter of the slide column 33. The slide column 33 is cylindrical, and each group of symmetrical slide plates 30 is provided with a slide column 33. The two ends of the bottom of the straight rod 34 are respectively fixedly connected to the symmetrical slide columns 33;

[0029] When in use, the symmetrical support frame 21 is flipped from the rectangular groove of the load-bearing frame 20 to a vertical state, and the cylinder 22 is placed on the ground. After the support frame 21 is flipped to the vertical state, the straight rod 34 drives the sliding column 33 to move downward, so that the sliding column 33 moves from the original vertical groove 32 to the horizontal groove 31, thereby fixing the position of the symmetrical support frame 21, and then placing it on the ground to be supported and controlling the lifting of the cylinder 22. After the lifting and lowering control of the cylinder 22 is completed, another identical device is placed in the same steps, and then the connecting rod 35 on one of the devices is flipped toward the other device, and after the connecting rod 35 is flipped, the corresponding card block 36 is inserted into the card groove 37 on the other device to complete the connection. When the device needs to be disassembled, the height of the cylinder 22 is first reduced, and then the connecting rod 35 is flipped to be parallel to the load-bearing frame 20, and then the straight rod 34 drives the sliding column 33 to move to the vertical groove 32 position. At this time, the support frame 21 drives the cylinder 22 to flip toward the rectangular groove at the bottom of the cavity of the load-bearing frame 20 to complete the folding;

[0030] In summary, by setting up a folding structure, it can be quickly assembled and folded, because the folding structure only needs to rotate the symmetrical support frame 21 and the connecting rod 35 when in use, and the same method is used for folding when disassembling. This process only requires one or two people to complete quickly, so compared with the existing technology, the conditions for use of this solution are simpler and it is more convenient to disassemble.

[0031] like Figure 2 and Figure 4As shown, a connecting rod 35 is rotatably connected to one side wall of the load-bearing frame 20, a clamping block 36 is fixedly connected to the end of the connecting rod 35, a net-loading box 38 is fixedly connected to the side wall of the connecting rod 35, a clamping groove 37 is provided on the other wall of the load-bearing frame 20 symmetrical to the connecting rod 35, a net-collecting roller 39 is rotatably connected to the wall of the net-loading box 38, the connecting rod 35 is symmetrically rotatably connected to the side wall of the load-bearing frame 20, each end of the connecting rod 35 is fixedly connected to the clamping block 36, a groove adapted to the net-collecting roller 39 is provided on the side wall of the net-loading box 38, the net-collecting roller 39 is rotatably connected in the groove of the net-loading box 38, and the clamping groove 37 can adapt to the size of the clamping block 36;

[0032] In specific use, the wall of the net collecting roller 39 is wrapped with a net to prevent falling rocks. After the adjacent devices are assembled, the net collected by the wall of the net collecting roller 39 can be connected and tightened with the net on the wall of another symmetrical net collecting roller 39 to prevent falling rocks. When collecting, the net can be wrapped around the wall of the net collecting roller 39.

[0033] In summary, by providing the net collecting roller 39, the net collected on the wall can be connected after the device is assembled, thereby preventing falling rocks from the top of the patio from falling and injuring workers, thereby ensuring the safety of workers at work.

[0034] Working principle: the symmetrical support frame 21 is flipped from the rectangular groove of the load-bearing frame 20 to a vertical state, and the cylinder 22 is placed on the ground. After the support frame 21 is flipped to the vertical state, the straight rod 34 drives the sliding column 33 to move downward, so that the sliding column 33 moves from the original vertical groove 32 to the horizontal groove 31, thereby fixing the position of the symmetrical support frame 21, and then placing it on the ground to be supported and then controlling the lifting of the cylinder 22. After the lifting and lowering control of the cylinder 22 is completed, another identical device is placed in the same steps, and then the connecting rod 35 on one of the devices is flipped toward the other device, and after the connecting rod 35 is flipped, the corresponding card block 36 is inserted into the card groove 37 on the other device to complete the connection. When the device needs to be disassembled, the height of the cylinder 22 is first reduced, and then the connecting rod 35 is flipped and parallel to the load-bearing frame 20, and then the straight rod 34 drives the sliding column 33 to move to the vertical groove 32 position. At this time, the support frame 21 drives the cylinder 22 to flip toward the rectangular groove at the bottom of the cavity of the load-bearing frame 20 to complete the folding.
