[0032] Specifically, the utility model provides an adaptively adjustable pipe culvert hoist for hoisting pipe culverts, which comprises a connecting rod 1, a load-bearing beam 2, a hanging beam 3 and a plurality of adjustment components 4. The load-bearing beam 2 is vertically fixed to the lower end of the connecting rod 1, and the hanging beam 3 is vertically fixed to the upper end of the connecting rod 1 to form a "U"-shaped structure, which is convenient for the load-bearing beam 2 to extend into the interior of the culvert; a plurality of adjustment components 4 are arranged on the outer wall of the load-bearing beam 2 at intervals along the axial direction of the load-bearing beam 2, and one end of each adjustment component 4 is fixedly connected to the outer wall of the load-bearing beam 2, and the other end of each adjustment component 4 is against the inner wall of the culvert to adjust the position of each adjustment component 4 according to the deformation of the inner wall of the culvert, and support and fix the pipe culvert in combination with the load-bearing beam 2, thereby ensuring the stability of the pipe culvert during the hoisting process and improving the efficiency of the pipe culvert hoisting.

[0033] In some possible embodiments, see Figure 2 Each of the adjustment components 4 includes a plurality of adjustment support members 41, and the plurality of adjustment support members 41 are arranged on the outer wall of the load-bearing beam 2 at intervals along the circumferential direction of the load-bearing beam 2. One end of each of the adjustment support members 41 is fixedly connected to the outer wall of the load-bearing beam 2, and the other end of each of the adjustment support members 41 is against the inner wall of the culvert.

[0034] Those skilled in the art can understand that each adjustment component 4 includes a plurality of adjustment support members 41, and the plurality of adjustment support members 41 are arranged on the outer wall of the load-bearing beam 2 at intervals along the circumferential direction of the load-bearing beam 2, and one end of each adjustment support member 41 is fixedly connected to the outer wall of the load-bearing beam 2, and the other end of each adjustment support member 41 is against the inner wall of the culvert, so that the load-bearing beam 2 and the adjustment component 4 form a whole, which is convenient for supporting and fixing the culvert.

[0035] In some possible embodiments, see Figure 3 and Figure 4 Each of the adjustment support members 41 includes: a support arm 411, the bottom end of which is fixedly connected to the outer wall of the load-bearing beam 2, and the support arm 411 is a hollow cylinder, forming an accommodating space; a support plate 412, one end of which is arranged in the accommodating space, and the outer wall of the support plate 412 is slidably connected to the inner wall of the support arm 411, a spring 413, one end of which is fixedly connected to the top end of the support arm 411, and the other end of the spring 413 is fixedly connected to the other end of the support plate 412; a support pad 414, one end of which is fixedly connected to the top of the other end of the support plate 412, and the other end of the support pad 414 is against the inner wall of the culvert.

[0036] This is because each adjustment support member 41 includes a support arm 411, a support plate 412, a spring 413 and a support pad 414. The support arm 411 is a hollow cylinder, and its inner wall constitutes an accommodating space. The bottom end of the support arm 411 is fixedly connected to the outer wall of the load-bearing beam 2, and the top end of the support arm 411 is fixedly connected to one end of the spring 413. One end of the support plate 412 is arranged in the accommodating space, and the outer wall of the support plate 412 is slidably connected to the inside of the support arm 411, so that the support plate 412 can slide freely in the accommodating space of the support arm 411; the other end of the spring 413 is fixed to the other end of the support plate 412, and a support pad 414 is arranged on the top of the other end of the support plate 412, and the support pad 414 is against the inner wall of the culvert. The position of the support plate 412 in the support arm 411 is adjusted by the deformation of the spring 413 to adapt to the deformation of the culvert under stress, thereby ensuring the stability of the culvert during transportation.

[0037] In some possible embodiments, the support plate 412 includes a horizontal plate and a vertical rod, and the vertical rod is vertically fixed in the middle of the horizontal plate to form a "T"-shaped structure; the outer wall of the vertical rod is slidably connected to the inner wall of the support arm 411, and a protrusion is provided at one end of the vertical rod away from the horizontal plate, and the protrusion is located in the accommodating space.

[0038] Those skilled in the art will appreciate that the support plate 412 includes a horizontal plate and a vertical rod, the vertical rod is vertically fixed in the middle of the horizontal plate to form a "T"-shaped structure, a protrusion is provided at one end of the vertical rod away from the horizontal plate, and the protrusion is located in the accommodating space to prevent the vertical rod from detaching from the support arm 411.

[0039] In some possible embodiments, the spring 413 surrounds the outer wall of the vertical rod, and the other end of the spring 413 is fixedly connected to the horizontal plate; the spring 413 is made of high-carbon alloy steel.

[0040] This is because the spring 413 is wrapped around the outer wall of the vertical rod, and the other end of the spring 413 is fixedly connected to the cross plate. The spring 413 is located between the support arm 411 and the cross plate, and the spring 413 is pressed by the cross plate to deform the spring 413. The spring 413 made of high-carbon alloy steel has high strength and high elastic limit, which can extend the service life of the culvert hanger.

[0041] In some possible embodiments, the support pad 414 is made of elastic material.

[0042] Those skilled in the art can understand that when the support pad 414 is made of elastic material, it can not only fit closely with the inner wall of the culvert, but also provide sufficient friction to prevent damage to the culvert during transportation. When the support pad 414 contacts the inner wall of the culvert, it can absorb its deformation and transfer it to the cross plate, and use the cross plate to press the spring 413, thereby causing the spring 413 to deform, so as to adapt to the deformation of the culvert during transportation, and can be combined with each adjustment support member 41 to support and fix the culvert.

[0043] In some possible embodiments, the pipe culvert hanger further includes: a lifting ring 5 , wherein the lifting ring 5 is arranged on an end of the hanging beam 3 away from the connecting rod 1 .

[0044] This is because the lifting ring 5 is set on one end of the hanging beam 3 away from the connecting rod 1 to facilitate the connection of the lifting equipment. The lifting ring 5 and the lifting equipment can be connected by chains, wire ropes, etc. to ensure that the connection between the culvert hanger and the lifting equipment is firm and reliable.

[0045] In some possible embodiments, the length of the load-bearing beam 2 is greater than the length of the hanging beam 3 .

[0046] Those skilled in the art will appreciate that the length of the load-bearing beam 2 is greater than the length of the hanging beam 3, which is beneficial for placing the pipe culvert under the lifting ring 5. When the sling is lifted using a lifting device, the stress on the load-bearing beam 2 can be balanced, thereby avoiding tilting and movement of the pipe culvert during transportation, thereby maintaining a stable lifting effect.

[0047] In some possible embodiments, the load-bearing beam 2 is fixedly connected to the lower end of the connecting rod 1 by a high-strength bolt 6 .

[0048] In order to improve the bearing capacity and stability of the load-bearing beam 2, the load-bearing beam 2 and the lower ends of the connecting rod 1 are fixed by high-strength bolts 6, and the load-bearing beam 2 can adopt a circular tubular structure.

[0049] In some possible embodiments, the connecting rod 1 , the load-bearing beam 2 , and the hanging beam 3 are all made of high-strength steel.

[0050] The utility model provides an adaptively adjustable pipe culvert hoist with the following working principles: first, the lifting ring 5 is firmly connected to the lifting equipment; secondly, the load-bearing beam 2 is inserted into the interior of the pipe culvert to be transported, and the relative position of the load-bearing beam 2 and the pipe culvert is adjusted so that the load-bearing beam 2 is in an appropriate position, and at the same time, the hoist is slowly lifted so that the support pad 414 is in close contact with the inner wall of the pipe culvert, and combined with the spring 413 to adapt to the arc change inside the pipe culvert, the stability of the contact between the pipe culvert and the hoist is maintained; then the lifting equipment is used to transport the pipe culvert and the hoist with stable contact to the designated position; finally, after the pipe culvert reaches the designated position, the load-bearing beam 2 is removed from the interior of the pipe culvert to complete the lifting of the pipe culvert.

[0051] Compared with the prior art, the technical solution provided by the utility model has the following advantages:

[0052] (1) The pipe culvert hoist of the utility model can be adaptively adjusted as the arc of the pipe culvert changes during the hoisting process, thereby reducing stress concentration during the transportation of the pipe culvert and maintaining a stable hoisting effect;

[0053] (2) The utility model arranges a support pad 414 made of elastic material and a spring 413 made of high-carbon alloy steel in the adjustment component 4, so that the support pad 414 can fit the inner wall of the culvert, provide sufficient friction to prevent the culvert from falling, and transmit the generated deformation force to the spring 413, thereby achieving the purpose of shockproof and shock reduction;

[0054] (3) The pipe culvert hoist provided by the utility model has a simple structure, is easy to operate, safe and reliable, and is suitable for hoisting operations of pipe culverts of various specifications and shapes.

[0055] In summary, the utility model provides an adaptively adjustable pipe culvert hoist, which is suitable for pipe culverts with any arc-shaped cross-section. When the pipe culvert is hoisted, the load-bearing beam 2 penetrates into the pipe culvert segment, and the adjustment component 4 contacts the internal top surface of the pipe culvert to bear force. As the weight increases, the adjustment component 4 can be adaptively adjusted as the arc of the pipe culvert changes, and the contact area with the internal top surface of the pipe culvert gradually increases, thereby reducing the risk of damage to the pipe culvert caused by stress concentration and rigid contact. The pipe culvert hoist of the utility model has a simple structure and is easy to operate. It can effectively ensure the stability of the pipe culvert hoisting process and avoid damage, and has important advantages in improving project quality and saving project costs.
