[0020] See also Figure 1-5 , an embodiment provided by the utility model:
[0021] A pipe segment lifting belt anti-skid safety device, comprising a polyester belt 1, a polyester belt 2, a shield pipe segment 3 and a square wood 4, the shield pipe segment 3 is hoisted on the polyester belt 1 and the polyester belt 2, the surface of the polyester belt 1 is fixedly connected with an anti-skid belt 5, the surface of the polyester belt 2 is fixedly connected with an anti-skid belt 2, the surface of the anti-skid belt 2 is fixedly connected with a locking block 7, the surface of the anti-skid belt 2 is fixedly connected with a limiting belt 8, the surface of the locking block 7 is fixedly connected with a spring 9, and the surface of the spring 9 is fixedly connected with a limiting rod 1 0, an extension belt 11 is fixedly connected to the surface of the anti-skid belt 5, and a positioning hole 12 is opened on the surface of the extension belt 11. The anti-skid device connects the polyester belt 1 and the polyester belt 2 through the anti-skid belt 15 and the anti-skid belt 26, thereby preventing the polyester belt 1 and the polyester belt 2 from sliding during the process of hoisting the shield segment 3, thereby ensuring the safety of hoisting the shield segment 3, and at the same time being able to adjust the connection length between the polyester belt 1 and the polyester belt 22 according to the size of the segment, thereby improving the flexibility of the anti-skid device.
[0022] Furthermore, two groups of anti-slip belt 1 5 and anti-slip belt 2 6 are provided, and the locking block 7 is fixedly connected to the end of the anti-slip belt 2 6 away from the polyester belt 2 2. The locking block 7 connects the anti-slip belt 1 5 and the anti-slip belt 2 6 through the extension belt 11, thereby ensuring the position of the polyester belt 1 and the polyester belt 2 2 at the bottom of the shield segment 3, and preventing the polyester belt 1 and the polyester belt 2 2 from sliding at the bottom of the shield segment 3.
[0023] Furthermore, the limiting belt 8 is overall in a "U" shape. The limiting belt 8 is fixedly connected to the end of the anti-slip belt 6 away from the polyester belt 2. There are multiple groups of limiting belts 8, which are linearly and evenly arranged on the surface of the anti-slip belt 6. The limiting belt 8 limits the position of the extension belt 11 on the anti-slip belt 6, so that the extension belt 11 fits on the surface of the anti-slip belt 6. Since the limiting belts 8 are densely arranged, the limiting belts 8 can effectively support the positioning holes 12 of different lengths on the anti-slip belt 6.
[0024] Furthermore, the locking block 7 is plate-shaped as a whole, and a rectangular hole is opened on the side of the locking block 7. The extension belt 11 slides on the rectangular hole of the locking block 7. The extension belt 11 passes through the circular hole of the locking block 7. The extension belt 11 is connected to each other through the locking block 7 and the anti-slip belt 2 6. The extension belt 11 needs to be fixed on the locking block 7, and the positioning hole 12 is the fixing point of the extension belt 11 on the locking block 7.
[0025] Furthermore, a circular hole is opened on the surface of the locking block 7, and the limiting rod 10 slides on the circular hole of the locking block 7. The rectangular hole of the extension belt 11 is connected to the circular hole of the extension belt 11. During the sliding of the limiting rod 10 on the circular hole of the locking block 7, the limiting rod 10 will pass through the rectangular hole of the locking block 7, thereby limiting the extension belt 11 on the rectangular hole of the locking block 7.
[0026] Furthermore, multiple groups of positioning holes 12 are provided and are linearly and evenly arranged on the surface of the extension belt 11. The arrangement of multiple groups of positioning holes 12 can adjust the distance between the anti-slip belt 1 5 and the anti-slip belt 2 6, thereby changing the distance between the polyester belt 1 and the polyester belt 2 2, and can hoist shield segments 3 of different specifications.
[0027] Furthermore, the spring 9 is sleeved on the surface of the limit rod 10, and the elastic force of the spring 9 acts on the surface of the limit rod 10. The limit rod 10 passes through the positioning hole 12 on the locking block 7. The limit rod 10 limits the extension belt 11 on the anti-slip belt 2 6 through the positioning hole 12, so that the extension belt 11 connects the anti-slip belt 1 5 and the anti-slip belt 2 6 together. The anti-slip belt 1 5 and the anti-slip belt 2 6 limit the position of the polyester belt 1 1 and the polyester belt 2 2 at the bottom of the shield segment 3, thereby preventing the polyester belt 1 1 and the polyester belt 2 2 from sliding at the bottom of the shield segment 3.
[0028] Working principle: In order to prevent the shield segment 3 from sliding on the polyester belt 1 and the polyester belt 2, the extension belt 11 on the anti-skid belt 5 is passed through the rectangular hole of the locking block 7, and the position of the extension belt 11 on the rectangular hole of the locking block 7 is adjusted so that one group of positioning holes 12 is aligned with the rectangular hole of the locking block 7. The spring 9 uses elastic force to make the limit rod 10 pass through the positioning hole 12 on the rectangular hole of the locking block 7. The limit rod 10 limits the position of the extension belt 11 on the locking block 7. The anti-skid belt 15 is connected with the anti-skid belt 26 through the extension belt 11. The anti-skid belt 15 and the anti-skid belt 26 limit the distance between the polyester belt 1 and the polyester belt 22, thereby preventing the polyester belt 1 and the polyester belt 22 from sliding on the shield segment 3. At the same time, the extension belt 11 is fixed at a fixed position on the locking block 7, which determines the distance between the anti-skid belt 15 and the anti-skid belt 26, and then determines the distance between the polyester belt 1 and the polyester belt 22.
