Description

Technical Field

[0001] This utility model belongs to the field of chemical pipeline hoisting and construction technology, and in particular relates to a chemical pipeline hoisting and installation device. Background Technology

[0002] During the installation and construction of chemical plants, a large amount of pipeline construction is required in their basic infrastructure. As an important infrastructure for transporting materials for chemical equipment, pipelines are crucial in the process of chemical infrastructure construction.

[0003] Specifically, for chemical production enterprises, pipeline structures are complex, resulting in a large workload and high operational difficulty in pipeline construction. For example, during the construction of densely laid pipelines, it is necessary to suspend a large number of large-diameter, long, and heavy pipes at high positions for installation. Current hoisting methods involve tying ropes to the outer wall of the pipe and lifting it at an angle. However, this method has significant technical drawbacks:

[0004] Firstly, for straight pipes, when steel wire ropes are tied to the outer wall of the pipe in a binding manner, the cylindrical pipe structure is prone to slipping with the binding position of the steel wire rope in the hanging state. This causes the pipe to slip down during hoisting, and slip to the joint position on the pipe. Under the huge impact force, the steel wire rope can easily deform the joint.

[0005] During actual hoisting operations, a serious safety accident occurred when the steel wire rope sliding down the pipe broke off the vertically welded flange interface pipe on the pipe.

[0006] Furthermore, during the hoisting process, only a single steel cable can currently be fixed. After hoisting, the pipe cannot be guaranteed to be hoisted vertically. Therefore, during construction, operators often need to attach a rope below the pipe (this operation method is extremely dangerous, as a pipe falling unexpectedly would cause a serious accident). After the crane lifts the pipe high into the air, it straightens the tilted pipe to facilitate hoisting it vertically and avoids hoisting it at an angle. A tilted and swaying pipe is more prone to impact (in a vertical position, the pipe's center of gravity is located on the central axis, making it less prone to violent swaying during hoisting).

[0007] Therefore, it is crucial to improve construction safety by vertically hoisting pipelines and ensuring that the hoisting of large pipelines is carried out under stable and safe conditions. Utility Model Content

[0008] Based on the above background, the purpose of this utility model is to provide a chemical pipeline hoisting and installation device.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A chemical pipeline hoisting and installation device includes a hoisting mechanism, which includes a support base that supports the bottom of the pipeline during hoisting. A hoisting net cage structure is assembled and connected to the support base, and the hoisting net cage structure includes a plurality of hoisting ropes.

[0011] The suspension rope includes an outer rope portion that abuts against the outside of the pipe and an inner rope portion that abuts against the inside of the pipe; the inner rope portions form an inner net cage structure that supports the inner wall of the pipe, and the outer rope portions form an outer net cage structure that supports the inner and outer walls of the pipe.

[0012] Both the bottom of the outer rope and the inner rope can be detached and hung on the support.

[0013] The suspension net structure also includes several hoop structures distributed along the length of the outer rope section, which are used to tighten the suspension rope;

[0014] The top of the hoisting rope is equipped with an upper hoisting rope structure, which is attached to the crane.

[0015] Preferably, the bottom of the outer rope is connected to the support via a first detachable hook structure.

[0016] Preferably, the first detachable pull-hanging structure includes a pull-hanging opening on the outer wall of the support, a support welded inside the pull-hanging opening, a screw threadedly connected to the support, the screw threadedly connected to the support, a pull-hanging seat fixedly connected to the bottom of the outer rope part, and the screw threadedly connected to the support after passing through the through hole on the pull-hanging seat.

[0017] Preferably, the bottom of the inner rope is connected to the support via a second detachable hook structure.

[0018] Preferably, the second detachable hanging structure includes a T-shaped limiting through hole opened on the bracket, a T-shaped rod limiting the T-shaped through hole, the top of the T-shaped rod protruding from the top surface of the bracket, and a hanging ring threaded to the top of the T-shaped rod;

[0019] The bottom of the inner rope is attached to the hanging ring.

[0020] Preferably, the top of the outer rope portion and the inner rope portion are integrally formed with a hanging portion, and the upper rope structure is hung on the hanging portion.

[0021] Preferably, the lifting rope structure includes a plurality of lifting ropes, and the hook on the crane is attached to the center of the lifting ropes;

[0022] Both ends of the hoisting rope are fixedly connected to a lifting ring, and a safety buckle is attached to the lifting ring and the safety buckle is attached to the hanging part.

[0023] Preferably, the hoop structure includes a hoop seat fixedly connected to the outer rope section, a hoop is fixedly connected to the hoop seat, and a hook claw is fixedly connected to the outer end of the hoop. After the hoop tightens the outer net cage structure, it is pulled and hung on the outer rope section by the hook claw.

[0024] Preferably, the hoop seat includes a pair of bracket seats arranged vertically at intervals, and the bracket seats are fixedly connected to the outer rope portion;

[0025] A hanging rod is fixedly connected between the bracket seats, and the inner end of the hoop rope is pulled on the hanging rod.

[0026] This utility model has the following beneficial effects:

[0027] 1. This method of suspending the pipeline is not only highly safe, but also keeps the pipeline vertically suspended. Furthermore, because the center of the pipeline is vertically downward and located on the pipeline axis when it is suspended, the suspended pipeline is less likely to sway, greatly reducing the probability of impact.

[0028] 2. During the hoisting process, each hoisting rope passes through the pipe cavity. The rope is then bent to form an outer rope section supporting the outer wall of the pipe. With the above operation of several hoisting ropes, the inner and outer walls of the pipe are supported by a cage-like structure consisting of the outer and inner rope sections. This method provides greater stability during hoisting, preventing slippage between the pipe and the hoisting ropes.

[0029] 3. By using a hoop structure, the rope is secured to the pipe segment by segment along the length of the hoisting rope, preventing severe friction between the rope and the pipe during hoisting. This protects the pipe and further increases the stability and safety of the hoisting process. Attached Figure Description

[0041] Example 1

[0042] like Figure 1-6As shown, a chemical pipeline hoisting and installation device includes a hanging mechanism. The hanging mechanism includes a support 2 that supports the bottom of the pipeline 1 during hoisting. A hanging net cage structure is assembled and connected to the support 2. The hanging net cage structure forms a columnar net cage structure to hoist the pipeline 1. This method is not only highly safe, but also keeps the pipeline 1 vertically hoisted. Furthermore, because the center of the pipeline 1 is vertically downward and located on the axis of the pipeline 1 in the vertically hoisted posture, the hoisted pipeline 1 is not easy to sway, and the probability of collision is greatly reduced.

[0043] Specifically, the suspended cage structure includes several circumferentially distributed suspension ropes 3 (the suspension ropes 3 are thickened steel wire ropes).

[0044] The suspension rope 3 includes an outer rope portion 31 that abuts against the outside of the pipe 1 and an inner rope portion 32 that abuts against the inside of the pipe 1; the inner rope portions 32 form an inner net cage structure supporting the inner wall of the pipe 1, and the outer rope portions 31 form an outer net cage structure supporting the inner and outer walls of the pipe 1. The pipe 1 is essentially suspended on the inner and outer double net cage structure, which provides higher stability.

[0045] Specifically, during the hoisting process, each hoisting rope 3 first passes through the cavity of the pipe 1 (the steel rope has a certain rigidity, making it easy to push through from one end of the pipe 1 to the other). Then, the steel rope is bent to form an outer rope section 31 that supports the outer wall of the pipe 1. With the above operation of several hoisting ropes 3, the inner and outer walls of the pipe 1 are supported by a cage structure shaped like the outer rope section 31 and the inner rope section 32. This method provides higher stability during hoisting, preventing slippage between the pipe 1 and the hoisting ropes 3.

[0046] The bottom of both the outer rope portion 31 and the inner rope portion 32 can be detached and hung on the support 2. After hoisting to the designated position, the hoisting rope 3 can be easily unlocked and removed from the pipe 1 as it is lowered.

[0047] Example 2

[0048] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 1, the bottom of the outer rope 31 is connected to the support 2 by a first detachable hook structure.

[0049] Specifically, the first detachable hook structure includes a hook opening (rectangular in shape) on the outer wall of the support 2. A support 21 (rectangular in shape, with a screw 22 threadedly connected to the support 21) is welded inside the hook opening. The screw 22 is threadedly connected to the support 21. A hook seat 311 is fixedly connected to the bottom of the outer rope part 31. The screw 22 passes through the through hole on the hook seat 311 and is threadedly connected to the support 2 (i.e., threadedly connected to the threaded groove on the side wall of the hook opening, thereby locking the outer rope part 31).

[0050] The bottom of the inner rope portion 32 is connected to the support 2 via a second detachable hook structure. The second detachable hook structure includes a T-shaped limiting through hole A (the upper end of the T-shaped limiting through hole A is smaller and the lower end is larger) opened on the support 2. A T-shaped rod 3211 (the T-shaped rod 3211 is a cylindrical steel rod with a T-shaped structure) is limited inside the T-shaped limiting through hole A. The top of the T-shaped rod 3211 protrudes from the top surface of the support 2. A hanging ring 321 is threadedly connected to the top of the T-shaped rod 3211 (specifically, the hanging ring 321 includes a ring body and a hanging ring screw welded to the ring body, and the hanging ring screw is threadedly connected to the T-shaped rod 3211); the bottom of the inner rope portion 32 is hooked onto the hanging ring 321. Specifically, the bottom of the inner rope section 32 is formed into a hanging ring (in practice, the hanging ring structure at the free end of the wire rope can be formed by bending the wire rope into a ring and then fixing it in shape, such as by welding), and the hanging ring 321 is pulled and hung on the bottom of the inner rope section 32.

[0051] Lifting Operation: First, thread the hanging ring 321 on each lifting rope 3 onto the T-shaped rod 3211. Then, pull the outer rope portion 31 of each lifting rope 3 towards the support 2. During the tightening process, the T-shaped rod 3211 is engaged into the T-shaped limiting through hole A and is limited within the T-shaped limiting through hole A. Next, the operator engages the hanging bracket 311 at the free end of the outer rope portion 31 into the hanging opening and passes the screw 22 through the hanging bracket 311 and tightens it, completing the installation of the lifting rope 3.

[0052] Once the hoisting is in place, the operators first remove the free end of the outer rope 31, and then pull the support 2 and the hoisting rope 3 from the pipe 1.

[0053] The whole process is not only simple to operate, such as the installation of the lifting rope 3 and the disassembly of the lifting rope 3 after hoisting and releasing the material, it is only necessary to loosen the screw 22 (while the traditional bolting method is very difficult to unlock the bolting position after the rope is tightened).

[0054] Example 3

[0055] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 2, the top of the outer rope part 31 and the inner rope part 32 are integrally formed with a hanging part, and the upper rope 3 structure is hung on the hanging part.

[0056] The upper rope 3 structure includes several upper ropes 52, and the hook on the crane is attached to the center of the upper rope 52. Specifically, the two ends of the upper rope 52 are respectively fixedly connected to the lifting ring body 521, and the lifting ring body 521 is attached to the safety buckle 51, which is attached to the hanging part.

[0057] Specifically, six hanging ropes 52 are used (or a steel wire rope formed into a radial shape by six hanging ropes 52 can be used instead). The two ends of each hanging rope 52 are fixedly connected to the lifting ring body 521. The hanging method is as follows: the lifting ring body 521 at both ends of each hanging rope 52 hangs the two hanging parts at the diagonal position (that is, the hanging rope 52 is hung along the diameter direction of the pipe 1).

[0058] The safety buckles 51 are attached to the lifting ring and the hanging part respectively, and then the hook of the crane is attached to the center of the upper lifting rope 52. The safety buckles 51 are the safety buckles commonly used in existing engineering construction. They have the same structure as existing safety buckles 51, including a buckle ring body and a buckle rod installed on the buckle ring body. Pressing the buckle rod opens the safety buckle 51 for hanging, and releasing the buckle rod forms a closed state after the buckle rod engages, thus locking the crane.

[0059] Example 4

[0060] like Figure 1-6 As shown, this embodiment is based on the structure of embodiment 3. During the hoisting process, in order to tighten the hoisting net structure segment by segment along the length (after tightening, the hoisting rope 3 is close to the pipe 1 and kept taut, firstly to reduce the friction between the hoisting rope 3 and the pipe 1, which would cause friction between the inner and outer walls of the pipe 1 and damage the pipe 1, and secondly to further increase the stability during the hoisting process and ensure that the pipe 1 is hoisted vertically).

[0061] Specifically, the hanging net structure also includes several hoop structures 4 distributed along the length of the outer rope section 31. The hoop structures 4 are used to tighten the hanging rope 3. The hoop structure 4 includes a hoop seat fixedly connected to the outer rope section 31. A hoop 43 is fixedly connected to the hoop seat. A hook claw 431 is fixedly connected to the outer end of the hoop 43. After the hoop 43 tightens the outer net cage structure, it is pulled and hung on the outer rope section 31 through the hook claw 431.

[0062] During operation, the hoop rope 43 is wound around the outer wall of pipe 1 along its circumferential direction. With the hoop rope 43 tightened, all the outer rope portions 31 on the outer wall of pipe 1 are clamped and tightly adhered to the pipe wall. After all the hoop ropes 43 are tightened, the hook claw 431 is pulled onto the outer rope portion 31 of one of the lifting ropes 3, achieving a locking effect after tightening.

[0063] Specifically, the hoop 43 seat includes a pair of bracket seats 41 arranged at intervals, the bracket seats 41 being fixedly connected to the outer rope part 31; a hanging rod 42 is fixedly connected between the bracket seats 41, and the inner end of the hoop 43 is pulled on the hanging rod (such as the inner end of the hoop 43 being tied and fixedly pulled on the hanging rod 42).

[0064] During the actual construction process, before hoisting, pipe 1 was in a flat position. After pipe 1 was slightly lifted, it was slightly separated from the ground. At this time, the hoop rope 43 was tightened.

[0065] In actual operation, existing technologies often use pads to support both ends of the horizontally lying pipe 1 for easy tying during suspension, allowing ropes to pass through the bottom of the pipe 1. Therefore, in practice, the existing method can also be followed, with pads placed at both ends of the horizontally lying pipe 1 before proceeding with the operation as described above.

[0066] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
