[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please refer to Figures 1 to 4. An embodiment of this utility model provides a hoisting device, which includes:

[0032] The fixing frame 1 consists of two symmetrically arranged sets, including a base frame 11 and an arched bracket 12 rotatably connected to the base frame 11. The base frame 11 has a V-shaped storage groove 14 for placing pipes on its upper part.

[0033] The fastening part 2 consists of a connecting part and a positioning part. The connecting part is fixed to the card holder 12, while the positioning part is fixed to the base frame 11. When the two are fastened together, they fix the base frame 11 and the card holder 12.

[0034] The compression fastener 3 is installed on the card holder 12 and includes a compression block 38 that can extend into the V-shaped storage groove 14 and compress the pipe.

[0035] A hook 4, which can be connected to the steel cable 5, is also fixed on the compression fastener 3.

[0036] It should be noted that metal is the preferred material for the entire device, as it can increase the counterweight. With a larger counterweight, the pressure exerted on the pipe by the compression fastener 3 will be greater, resulting in a better fixation effect on the pipe.

[0037] The fixed frame 1 includes a base frame 11 and a bracket 12. The upper end of the base frame 11 has a V-shaped storage groove 14, which can be used to place the pipe to be hoisted. This type of storage groove can increase the applicable range. The bracket 12 is rotatably connected to the base frame 11. When it is open, it is convenient to place the pipe in the base frame 11. When it is closed, it can restrict the pipe to a certain extent.

[0038] The fastening part 2 is used to reinforce the connection between the base frame 11 and the card holder 12. That is, when the connecting part and the positioning part in the fastening part 2 are fastened together, the base frame 11 and the card holder 12 are in a stable fastening state to prevent them from separating.

[0039] The compression fastener 3 can exert radial compression on the pipe to cooperate with the base frame 11 to fix the pipe. It is also equipped with a hook 4 for connecting the steel cable 5 so as to suspend it on the hoisting equipment.

[0040] In an embodiment of this utility model, please refer to Figure 2. The lower end of the base frame 11 has a base 13, which is a metal block. A first rubber pad 15 is adhered to the inner wall of the V-shaped storage groove 14.

[0041] It should be noted that the base 13 is a supporting structure that can support the entire device. At the same time, a first rubber pad 15 is set inside the V-shaped storage groove 14, so that the pipe can be prevented from being damaged after the pipe is placed.

[0042] In an embodiment of this utility model, please refer to Figure 3. The connecting part includes a positioning block 21, which is welded and fixed to the card holder 12. A rotating shaft 22 is rotatably connected to the positioning block 21, and a connecting frame 23 is fixed on the rotating shaft 22. A card rod 25 is fixed at the other end of the connecting frame 23. A torsion spring 24 that abuts against the positioning block 21 is also sleeved on the rotating shaft 22.

[0043] The positioning part includes a positioning seat 26, one side of which has an obliquely placed slot 27, and the locking rod 25 can be inserted into the slot 27.

[0044] It should be noted that in the fastening component 2, the connecting frame 23 can rotate, and one end of it has a locking rod 25. The locking rod 25 can be fastened into the slot 27 in the positioning seat 26. Both are installed on the base frame 11 and the card holder 12 respectively. Therefore, in the fastened state, the base frame 11 and the card holder 12 can be limited.

[0045] In an embodiment of this utility model, please refer to Figure 4. The extrusion fixing member 3 includes a first sealing cylinder 31, which is fixed to the upper end of the card holder 12. A first piston 32 is axially slidable inside the first sealing cylinder 31. A first piston rod 33 is fixed to the upper end of the first piston 32. The first piston rod 33 extends through and above the first sealing cylinder 31 and is fixed to the hook 4.

[0046] A second sealing cylinder 34 is also provided on both sides of the first sealing cylinder 31 and fixed to the top of the card holder 12. A second piston 35 slides axially inside the second sealing cylinder 34. A second piston rod 36 is fixed to the lower end of the second piston 35. The second piston rod 36 extends through to the bottom of the card holder 12 and is fixed to the extrusion block 38. A second rubber block 39 is also bonded to the lower end of the extrusion block 38.

[0047] It should be noted that: the hook 4 is fixed to the upper end of the first piston rod 33. Therefore, during hoisting, the first piston rod 33 is subjected to tension and the gravity of the entire device and pipeline, which enables it to move relative to the first sealing cylinder 31. At this time, the first piston 32 compresses the gas inside the first sealing cylinder 31. The gas enters the second sealing cylinder 34 along the gas pipe 37. At this time, the second piston 35 is subjected to air pressure, causing the second piston rod 36 to move down until the second rubber block 39 contacts the pipeline and generates compression.

[0048] When the pipe itself is relatively light and the overall weight is relatively small, a counterweight can be added to the fixing bracket 1 to improve the fixing effect of the compression block 38 on the pipe.

[0049] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0050] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
