[0002] During the construction of municipal roads and buildings, the laying of water supply and drainage pipes is an important construction project. During the laying process, it is inevitable to lift and move the water supply and drainage pipes. Due to the long length of water supply and drainage pipes, the current construction method is mainly to use the pull-down cables of the lifting equipment to bundle the two ends of the water supply and drainage pipes for lifting.

[0003] The following problems currently exist during hoisting: (1) The outer wall of the water supply and drainage pipe is relatively smooth. Due to the influence of wind and operation, the water supply and drainage pipe is easy to slide during cable bundling and hoisting, which may cause the pipe to fall. In addition, some water supply and drainage pipes are made of plastic or concrete. When the cable bundling is hoisted, the contact points of the long and brittle water supply and drainage pipes are easily damaged. (2) When bundling and hoisting, after the pipe is in place, the cable rope is easily pressed under the pipe, making it inconvenient to remove. Utility Model Content

The upper parts of the left clamp structure 1 and the right clamp structure 2 are hinged through the clamp hinge column 5. The upper parts of the left clamp structure 1 and the right clamp structure 2 can be opened and closed around the clamp hinge column 5. After the left clamp structure 1 and the right clamp structure 2 are merged, a circular ring-shaped cavity is formed between the inner sides of their lower parts for clamping the water supply and drainage pipe; two handle frames 4 are symmetrically fixed to the outer sides of the middle parts of the left clamp structure 1 and the right clamp structure 2, and the two handle frames 4 are pulled outward to separate the lower parts of the left clamp structure 1 and the right clamp structure 2, so as to facilitate the release of the water supply and drainage pipe from the left and right clamp structures; the separation hook 6 is provided Placed on the upper part of the left clamp structure 1, the separation hook 6 is used to hook the pull-down cable of the lifting equipment. When lifting heavy water supply and drainage pipes, after the water supply and drainage pipe lifting clamp structure is placed on the ground, due to the resistance of the lower structure of the left clamp structure 1 and the right clamp structure 2 to the ground, it is not convenient to open the left and right clamp structures by manually pulling the handle frame 4. At this time, the pull-down cable of the hooking lifting equipment can be hooked on the separation hook 6, and the left clamp structure 1 can be pulled to open the left and right clamp structures to release the water supply and drainage pipes; two connecting buckles 10 are respectively arranged at the top of the left clamp structure 1 and the right clamp structure 2, and the pull-down cable of the hooking lifting equipment is hooked on the two connecting buckles 10, so that the lower parts of the left and right clamp structures move inward, clamping and lifting the water supply and drainage pipes.

[0022] Reference Figure 2 、 Figure 3 As shown, the left clamp structure 1 includes a left clamp rod 11; the right clamp structure 2 includes a right clamp rod 21 and a connecting ring 22. There are two right clamp rods 21, and the middle parts of the two right clamp rods 21 are connected by a connecting ring 22. An upper slot 25 is formed between the upper parts of the two right clamp rods 21, and a lower slot 26 is formed between the lower parts of the two right clamp rods 21. The upper part of the left clamp rod 11 is hinged in the upper slot 25 via the clamp hinge column 5, and the lower part of the left clamp rod 11 is inserted into the lower slot 26, so that the left clamp rod 11 and the right clamp rod 21 can rotate around the clamp hinge column 5.

[0023] Example 2

[0024] This embodiment provides a water supply and drainage pipe lifting fixture structure, based on the structure in embodiment 1, with reference to Figures 1 to 3As shown, the left clamp structure 1 also includes two load rings 12, which are symmetrically fixed to the front and rear ends of the left clamp rod 11. The separation hook 6 is fixed to the upper front end of the load ring 12 via the hook fastening bolt 7. The front and rear end surfaces of the two load rings 12 are aligned with the front and rear end surfaces of the two right clamp rods 21. The provision of two load rings 12 increases the central inner surface area of ​​the left clamp structure 1, which can improve the clamping friction when clamping the water supply and drainage pipe, and prevent it from moving and falling during lifting.

[0025] Furthermore, a circular gasket 13 is fixed on the inner side of the supporting ring 12, and a circular gasket 13 is also symmetrically fixed on the inner side of the two right clamping rods 21.

[0026] The working principle of the utility model: The utility model is a water supply and drainage pipe lifting clamp structure, the upper parts of the left clamp structure 1 and the right clamp structure 2 can be opened and closed around the clamp hinge column 5, and after the left clamp structure 1 and the right clamp structure 2 are combined, a circular cavity is formed between the inner sides of their lower parts for clamping the water supply and drainage pipes.

[0027] The left clamp structure 1 increases the inner surface area of ​​the middle part of the left clamp structure 1 by setting two supporting rings 12. Gaskets 13 with friction protrusions are also set on the inner sides of the left and right clamp structures to increase the clamping friction force on the water supply and drainage pipes and prevent them from moving and falling during lifting.

[0028] Two handle frames 4 are symmetrically fixed on the outer side of the middle of the left and right clamp structures. The two handle frames 4 are pulled outward to separate the lower part of the left clamp structure 1 and the right clamp structure 2, so as to facilitate the release of the water supply and drainage pipes from the left and right clamp structures; a separation hook 6 is also provided on the upper part of the left clamp structure 1 for hooking the pull-down cable of the lifting equipment. When lifting heavy water supply and drainage pipes, after the water supply and drainage pipe lifting clamp structure is placed on the ground, due to the resistance of the lower structures of the left clamp structure 1 and the right clamp structure 2 to the ground, it is not convenient to open the left and right clamp structures by manually pulling the handle frames 4. At this time, the pull-down cable of the hooked lifting equipment can be hooked on the separation hook 6, and the left clamp structure 1 can be pulled to open the left and right clamp structures to release the water supply and drainage pipes.
