Description

Technical Field

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

[0002] Pipeline construction is a frequent task in engineering construction. The difficulty of construction varies depending on the diameter and material of the pipeline.

[0003] Especially for large-diameter and long pipelines, their weight and length not only make them heavy, but also pose greater risks during hoisting and installation. In particular, if the pipeline loses its balance during hoisting and falls from a height, it can easily cause injuries to personnel and equipment. More seriously, due to its length, a falling pipeline can cause extensive damage, potentially leading to extremely serious safety accidents.

[0004] Specifically, in the current process of hoisting this type of pipeline, steel wire ropes are often tied to the pipeline, such as at both ends, to improve balance. However, since the pipeline wall is mostly smooth, even if the steel wire ropes are tied tightly before hoisting, the pipeline is prone to swaying when hoisted to a high altitude, especially after the crane changes direction. This can lead to slippage between the steel wire ropes and the pipeline. Once slippage occurs and the tying points change, the pipeline is very likely to lose its balance. Once it loses its balance, the pipeline is prone to tipping over, resulting in an operational safety accident.

[0005] Therefore, in existing technologies, steel wire ropes are often threaded through the inside of the pipe to increase safety. However, this method has a drawback: to enhance the pipe's corrosion resistance, especially for pipes transporting sewage, the inner wall of the pipe is often coated with a rust-proof and corrosion-resistant coating. However, in this method, because the contact area between the steel wire rope and the pipe is small and the pressure is extremely high, the internal coating of the pipe is easily damaged over a large area during hoisting (especially when the pipe shakes violently). This seriously affects the service life of the pipeline. Utility Model Content

[0006] Based on the above background, the purpose of this utility model is to provide a pipeline hoisting device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A pipe hoisting device includes a hanging clamp mechanism that is respectively hung at both ends of a pipe, and the hanging clamp mechanism is fixedly connected to the other two ends by a steel cable structure.

[0009] The hanging clamp mechanism is held and rolled on the pipe by a roller structure. The hanging clamp mechanism includes a pair of hanging clamp assemblies, and the hanging length is adjusted between the hanging clamp assemblies by a spacing adjustment structure.

[0010] The hanging clamp mechanism is equipped with several steel cable claw structures. The steel cable claw structures grip the pipe opening. During the hoisting process, the crane hoists and pulls the steel cable structure. The steel cable structure pulls the hanging clamp mechanisms on both sides closer to each other until the steel cable claw structure switches from a slack state to a taut state.

[0011] Preferably, the hanging clamp assembly includes a hanging bracket sleeved on the outside of the pipe, and a plurality of adjustable-spaced clamping roller structures are installed on the hanging bracket, with the pipe clamped between the clamping roller structures.

[0012] Preferably, the abutting roller structure includes a roller frame, on which an abutting roller is rotatably connected;

[0013] The hanging bracket is threaded with an adjusting screw, which is rotatably connected to the hanging wheel bracket.

[0014] Preferably, the longitudinal cross-sectional shape of the hanging bracket is square;

[0015] Each of the four sides of the hanging bracket is equipped with a clamping roller structure.

[0016] Preferably, the spacing adjustment structure includes several spacing adjustment screw components, each including a long adjustment screw, and protrusions that are slidably connected to the side walls of the front and rear hanging brackets respectively. Two pairs of nuts, respectively positioned on both sides of the protrusions, are threaded onto the long adjustment screw.

[0017] Preferably, four steel rope claw structures are fixedly installed on the outer hanging bracket;

[0018] The steel rope claw structure is fixed to the center of each side of the hanging bracket.

[0019] Preferably, the steel rope claw structure includes a steel wire rope, and the outer end of the steel wire rope is fixedly connected to a hook plate;

[0020] The hanging bracket is welded with a wire rope fixing seat to fix the wire rope.

[0021] Preferably, steel wire hanging rings are fixedly connected to both sides of the top of the inner hanging bracket;

[0022] The cable structure includes steel cables that are fixedly connected between steel wire hanging rings, and the crane is suspended at the center of the steel cables.

[0023] Preferably, the wire rope fixing seat has a through hole, through which the wire rope passes;

[0024] The wire rope is bolted and fixed at the through hole.

[0025] This utility model has the following beneficial effects:

[0026] 1. During the operation, when the crane lifts and pulls the steel cable structure, the hanging clamps at both ends roll rapidly toward the center of the pipe under the tension of the inclined upward steel cable structure. As the hanging clamps move, the steel rope claw structure that was pre-attached to the pipe opening gradually changes from a relaxed state to a taut state, thereby pulling the pipe opening in.

[0027] Therefore, in this method, because one end of the hanging clamp mechanism is subjected to the tension of the steel cable structure, while the other end is subjected to the anchoring tension of the steel rope claw structure and the pipe opening, the hanging clamp mechanism remains in a different position. The advantages of this method are: during the hoisting process, the position of the hanging clamp mechanism is not easy to loosen, and thus the balance of the pipeline will not be damaged. Secondly, the hanging clamp mechanism can hang a certain length range, thus further increasing the hoisting range.

[0028] 2. Once the pipe is hoisted to the target position, the lifting force disappears, and the steel cable claw structure automatically relaxes, facilitating the release of the pipe. Attached Figure Description

[0038] Example 1

[0039] like Figure 1-4 As shown, a pipe hoisting device includes a hanging clamp mechanism that is respectively suspended at both ends of a pipe 1, and a steel cable structure is fixedly connected between the hanging clamp mechanisms. The hanging clamp mechanism is held and rolled on the pipe 1 by a roller structure. The hanging clamp mechanism includes a pair of hanging clamp assemblies 2, and the hanging clamp assemblies 2 are adjusted for hanging length by a spacing adjustment structure. Several steel cable claw structures are installed on the hanging clamp mechanism. The steel cable claw structures grip the opening of the pipe 1. During hoisting, the crane hoists and pulls the steel cable structure, and the steel cable structure pulls the two hanging clamp mechanisms closer to each other until the steel cable claw structures switch from a slack state to a taut state.

[0040] In this way, during the operation, when the crane lifts and pulls the steel cable structure, the hanging clamps at both ends roll rapidly toward the center of pipe 1 under the tension of the inclined upward steel cable structure. As the hanging clamps move, the steel rope claw structure that is pre-hanging at the opening of pipe 1 gradually changes from a relaxed state to a taut state, thereby pulling the opening of pipe 1 inward.

[0041] Therefore, in this method, since one end of the hanging clamp mechanism is subjected to the tension of the steel cable structure, while the other end is subjected to the anchoring tension of the steel rope claw structure and the opening of pipe 1, the hanging clamp mechanism remains in a different position. The advantages of this method are: during the hoisting process, the position of the hanging clamp mechanism is not easy to loosen, and thus the balance of pipe 1 will not be damaged. Secondly, the hanging clamp mechanism can hang a certain length range, thus further increasing the hoisting range.

[0042] Even better, once the pipe is hoisted to the target position, the lifting force disappears, and the steel cable claw structure automatically relaxes, making it easy to release the pipe 1.

[0043] Example 2

[0044] like Figure 1-4 As shown, based on the structure of Embodiment 1, the above-mentioned hanging clamp assembly 2 includes a hanging bracket 21 sleeved on the outside of the pipe 1. Specifically, the longitudinal cross-sectional shape of the hanging bracket 21 is square, and several adjustable-spaced clamping roller structures 22 are installed on the hanging bracket 21 (specifically, a clamping roller structure 22 is installed at the center of each of the four sides of the hanging bracket 21), and the pipe 1 is clamped between the clamping roller structures 22.

[0045] Specifically, the clamping pulley structure 22 includes a pulley frame 221, on which a clamping pulley 222 is rotatably connected; an adjusting screw 223 is threadedly connected to the pull bracket 21, and the adjusting screw 223 is rotatably connected to the pulley frame 221. Specifically, a fixed seat 2231 for rotatably connecting the adjusting screw 223 is fixedly connected to the top of the pulley frame 221, similar to existing rotatable connection methods. A T-shaped limiting groove (not shown in the figure) is provided on the fixed seat 2231, and a rotating head (not shown in the figure) for rotatable connection within the limiting groove is fixedly connected to the bottom of the adjusting screw 223. The rotating head and the rod body of the adjusting screw 223 are integrally formed into a T-shaped structure.

[0046] During operation, adjust the four clamping rollers 222 structures 22 until they respectively clamp onto the pipe 1. The operation method is as follows: rotate the adjusting screw 223 and then adjust the clamping rollers 222 structures 22.

[0047] With the cooperation of a pair of hanging clamp assemblies 2, one end of the pipe 1 is clamped, and the clamping has a certain length, so the clamping stability is high.

[0048] Adjust the clamping length of a pair of hanging clamp assemblies 2 according to the weight and length of pipe 1.

[0049] Specifically, the spacing adjustment structure includes four spacing adjustment screws 3, with two spacing adjustment screws 3 arranged vertically and vertically on each side between the left and right sides of the front and rear hanging brackets 21.

[0050] Specifically, the spacing adjustment screw component 3 includes a long adjustment screw 31, and the front and rear sides of the hanging bracket 21 are respectively fixedly connected to the protrusions 311 that are slidably connected to the long adjustment screw 31. The long adjustment screw 31 is threaded with two pairs of nuts 32 that are respectively positioned on both sides of the protrusions 311.

[0051] After loosening nut 32, the distance between the front and rear hanging clamp assemblies 2 can be adjusted to adjust the clamping length. If the distance is increased, the clamping length will increase, allowing for the hanging of pipes 1 with larger lengths and diameters.

[0052] Example 3

[0053] like Figure 1-4 As shown, in this embodiment, based on the structure of embodiment 2, in order to anchor the pipe 1 and the hanging clamp assembly 2 during the hoisting process and increase stability and safety, four steel rope claw structures 4 are fixedly installed on the hanging bracket 21 located on the outer side (i.e., near the pipe 1 opening).

[0054] Specifically, the steel cable claw structure 4 is fixed to the center of each side of the hanging bracket 21. The steel cable claw structure 4 includes a steel wire rope 42, and the outer end of the steel wire rope 42 is fixedly connected to a hook plate 43; a steel wire rope fixing seat 41 for fixing the steel wire rope 42 is welded on the hanging bracket 21.

[0055] Meanwhile, a through hole is provided on the wire rope fixing seat 41, and the wire rope fixing seat 41 passes through the through hole; the wire rope fixing seat 41 is bolted and fixed at the through hole.

[0056] Before hoisting, hook plate 43 is attached to the opening of pipe 1. Meanwhile, because wire rope 42 is secured to the through hole, the anchoring point of wire rope 42 can be adjusted to adjust its length, facilitating hoisting.

[0057] During the hoisting process, the hanging bracket 21 rolls on the pipe 1 and gradually moves away from the opening of the pipe 1. At this time, the wire rope 42 gradually tightens and is then hooked onto the hook plate 43.

[0058] The top of the inner hanging bracket 21 is fixedly connected to two sides of the wire hanging ring body 51 respectively; the steel cable structure includes steel cable rope 5 (forming a V-shaped structure) fixedly connected between the wire hanging ring bodies 51 respectively, and the crane is suspended at the center of the steel cable rope 5.

[0059] The crane hook is attached to the center of the steel cable 5.

[0060] 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.
