Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline construction, and in particular relates to pipeline hoisting equipment used for pipeline construction. Background Art

[0002] Pipelines are crucial infrastructure in water conservancy projects, transporting water resources through their construction. To meet water supply needs, pipeline construction often involves large, long, and long pipes. During construction, the pipes are lowered into the trench using a crane, and then operators connect and weld the pipes together to seal them.

[0003] The large diameter, length, and smooth surface of the pipes make hoisting them challenging. Specifically, the wire ropes used to suspend the long pipes are difficult to maintain balance, resulting in one end being higher than the other. This makes it difficult to hoist the pipe horizontally. This results in poor hoisting stability and installation. Unbalanced hoisting can easily cause the heavy pipes to fall or collide, leading to deformation and reduced sealing.

[0004] Therefore, in order to ensure horizontal lifting during the lifting process, the position of the wire rope needs to be constantly corrected. However, since the smooth pipe is prone to relative slippage between the wire rope and the pipe during the lifting process, it is easy for the wire rope to slip during the lifting process, causing the balance to be lost again.

[0005] Moreover, the steel wire rope is tied to the pipe. Once the balance is found to be not high and the balance needs to be adjusted, the steel wire rope needs to be untied and adjusted again, which is very cumbersome. Therefore, how to make a pipe lifting device for pipeline construction that can solve the existing technical problems has become a technical problem to be solved. Utility Model Content

[0006] Based on the above technical problems, the present invention proposes a pipeline hoisting device for pipeline construction to solve the problems existing in the above background technology.

[0007] In view of this, the utility model proposes a pipeline lifting equipment for pipeline construction, which includes: a pipeline lifting mechanism, the pipeline lifting mechanism includes a rolling hanger assembly respectively arranged at both ends of the pipeline; the rolling hanger assembly includes a plurality of side rollers that support and roll on the side positions of the pipeline, and the side rollers are symmetrically distributed on both sides of the pipeline; the inner side walls of the side rollers are installed with side support rollers that support and roll on the pipeline; the rolling hanger assembly also includes top and bottom rollers that are detachably installed between the top and bottom of the side rollers, and a plurality of rollers that support and roll on the pipeline are installed on the top and bottom rollers; the rolling hanger assembly also includes a plurality of anchor claws on the pipeline mouth anchor claw parts; steel wire ropes are hung between the rolling hanger assemblies; during the lifting process, the lifting equipment is hung on the steel wire rope, and the steel wire rope pulls the rolling hanger assemblies on both sides close together until the anchor claws of the anchor claw parts are on the pipeline mouth.

[0008] Furthermore, the top and bottom roller frames include side frame parts arranged in parallel on the left and right sides, a plurality of connecting frame parts are integrally formed between the side frame parts, and the rollers are installed at the bottom of the connecting frame parts.

[0009] Furthermore, a lifting ring is fixedly connected to the top and bottom roller frames at the top position, and both ends of the steel wire rope are hung on the lifting ring.

[0010] Furthermore, the top and bottom of the side rolling frame are respectively fixedly connected with mounting screws; the mounting screws pass through the top and bottom rolling frames, and nuts are threadedly connected to the mounting screws.

[0011] Furthermore, a spring is sleeved on the mounting screw, one end of the spring is fixedly connected to the side rolling frame, and the other end of the spring is supported on the top and bottom rolling frames.

[0012] Furthermore, the sides of the side rolling frames and the top and bottom rolling frames are respectively fixedly connected with fluke components.

[0013] Furthermore, the fluke component includes a U-shaped fluke plate on the pipe mouth, and the U-shaped fluke plate is fixedly connected to a steel wire rope; the steel wire rope is fixed to the corresponding side roller frame and the top and bottom roller frame.

[0014] Furthermore, a protrusion is integrally formed on the outer side wall of the U-shaped claw plate; a hanging ring is hung on the protrusion, and the inner end of the steel wire rope is fixed on the hanging ring.

[0016] The utility model provides a pipeline hoisting device for pipeline construction. Compared with the existing technology, the utility model has the following advantages:

[0017] During the hoisting process, the hoisting equipment is suspended on the wire rope. Due to the upward pulling force, the wire rope pulls the rolling hanger assemblies at both ends, causing the rolling hanger assemblies to move toward the center of the pipeline and firmly grip the pipeline opening with the anchor claws. This method achieves a flexible and ingenious way to anchor and suspend the pipeline. Specifically, because the rolling hanger assemblies, which bear the primary force, are anchored, they will not move during the hoisting process, causing loss of balance.

[0018] After lowering the pipe, the lifting force disappears and the rolling hanger assembly no longer pulls the anchor claw component, allowing the anchor claw component to easily loosen from the pipe opening, making it easy to unlock the pipe. This method greatly improves the efficiency of lifting the pipe.

[0019] 2. The anchor claw component includes a U-shaped claw plate on the pipe mouth, and the U-shaped claw plate is fixedly connected to the wire rope; the wire rope is fixed to the corresponding side rolling frame and the top and bottom rolling frame.

[0020] Specifically, the outer wall of the U-shaped claw plate is integrally formed with a protrusion; a hook is attached to the protrusion, and the inner end of the wire rope is fixed to the hook. In this way, when the loaded rolling hanger assembly slides on the pipe, the wire rope pulls the U-shaped claw plate until it is taut at the mouth of the pipe, thereby holding the rolling hanger assembly in place and preventing it from sliding.

[0027] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited by the contents disclosed below.

[0029] The following combination Figures 1 to 5 The technical solution of the utility model is further explained.

[0030] The first embodiment, as Figures 1 to 5 The invention discloses a pipe hoisting device for pipeline construction, comprising a pipe hoisting mechanism, wherein the pipe hoisting mechanism comprises rolling hanger assemblies 2 respectively arranged at both ends of a pipe 1. The rolling hanger assemblies 2 are used to facilitate position adjustment during the hoisting process by rolling.

[0031] Specifically, the rolling hanger assembly 2 includes several side rollers 21 that support and roll against the sides of the pipe 1. These side rollers 21 are symmetrically distributed on either side of the pipe 1. Specifically, three side rollers 21 are evenly spaced on the left and right sides. Side support rollers 22 (including side roller frames, to which support rollers are rotatably connected) are mounted on the inner sidewalls of the side roller frames 21 to support and roll against the pipe 1.

[0032] At the same time, the rolling hanger assembly 2 also includes a top and bottom roller racks 23 that are detachably mounted between the top and bottom of the side roller racks 21, and the top and bottom roller racks 23 are mounted with a plurality of rollers 24 that support and roll on the pipe 1 (the rollers 24 include roller racks fixedly connected to the top and bottom roller racks 23, and the rollers 24 are rotatably connected to the roller racks).

[0033] The top and bottom roller frames 23 have a structural shape as follows: the top and bottom roller frames 23 include side frame portions arranged in parallel on the left and right sides, a plurality of connecting frame portions 231 are integrally formed between the side frame portions, and the rollers 24 are installed at the bottom of the connecting frame portions 231 .

[0034] During operation, the operator rolls the rolling hanger assemblies 2 on both sides on the pipe 1 (the rolling hanger assemblies 2 are assembled in advance, specifically, the top and bottom rollers 23 are detachably mounted for easy assembly). Roll the rolling hanger assemblies 2 to a position close to the pipe opening of the pipe 1.

[0035] The rolling hanger assembly 2 also includes several anchor claws that attach to the pipe opening. When the rolling hanger assembly 2 is rolled close to the pipe opening 1, the anchor claws are anchored there. After lifting, the rolling hanger assembly 2 is held in place, preventing it from slipping and maintaining proper balance.

[0036] Therefore, in this way, the pipe mouth of the pipe 1 can be grasped, so that the balance of the lifting can be maintained during the lifting process. Moreover, since the mouth of the pipe 1 is anchored, the pipe 1 will not slide sideways during the lifting process. This method greatly improves the stability and safety of the pipe 1 lifting.

[0037] Specifically, a steel wire rope 3 is hung between the rolling hanger assemblies 2. Specifically, a lifting ring 2311 is fixedly connected to the top and bottom rolling frames 23 at the top position, and both ends of the steel wire rope 3 are hung on the lifting ring 2311 (the lifting ring 2311 is fixed to the connecting frame part 231 in the middle).

[0038] During the hoisting process, the hoisting equipment is suspended on the wire rope 3. Due to the upward pulling force, the wire rope 3 pulls the rolling hanger assemblies 2 at both ends, causing the rolling hanger assemblies 2 to move toward the center of the pipeline 1 and firmly grip the pipeline opening with the anchor claw components. In this way, the pipeline 1 is anchored and suspended in a flexible and ingenious manner. Specifically, because the rolling hanger assemblies 2, which bear the primary force, are anchored, they will not move during the hoisting process, causing loss of balance.

[0039] After lowering the pipe 1, the lifting force disappears and the rolling hanger assembly 2 no longer pulls the fluke component, so the fluke component easily loosens from the pipe opening, making it easy to unlock the pipe 1. This greatly improves the efficiency of lifting the pipe 1.

[0040] The second embodiment, as Figures 1 to 5 As shown, the difference from the previous embodiment is that the top and bottom of the side rolling frame 21 are fixedly connected to mounting screws 26, which pass through the top and bottom rolling frames 23 and are threaded with nuts. A spring 261 is sleeved on the mounting screw 26, one end of which is fixedly connected to the side rolling frame 21, and the other end of which is supported by the top and bottom rolling frames 23.

[0041] After the nut is loosened, the top and bottom roller frames 23 are ejected under the elastic force of the spring 261 , thereby realizing quick disassembly of the top and bottom roller frames 23 .

[0042] During the rotation and lifting process, the top and bottom rollers 23 at the bottom position are subjected to a greater gravity. With the cooperation of the spring deformation, whether lifting the bulky pipe 1 or lowering the bulky pipe 1, the elastic deformation of the spring 261 is used to form a buffer to protect the pipe 1 (the elastic deformation of the spring 261 to form a buffer is a conventional application based on the inherent properties of the spring in the prior art).

[0043] Example 3

[0044] like Figure 1-5 As shown, based on the structure of Example 2, this embodiment has anchor claw components fixedly connected to the sides of the side rolling frames 21 and the top and bottom rolling frames 23, respectively, so that the four anchor claw components can be anchored from the mouth of the pipe 1 in four directions: up, down, left, and right.

[0045] Specifically, the fluke assembly includes a U-shaped fluke plate 25 on the pipe mouth, and a steel wire rope 251 is fixedly connected to the U-shaped fluke plate 25; the steel wire rope 251 is fixed to the corresponding side roller frame 21 and the top and bottom roller frames 23.

[0046] Specifically, a protrusion is integrally formed on the outer side wall of the U-shaped claw plate 25 ; a hanging ring is hung on the protrusion, and the inner end of the steel wire rope 251 is fixed on the hanging ring.

[0047] In this way, when the stressed rolling hanger assembly 2 slides on the pipe 1 , the steel wire rope pulls the U-shaped claw plate 25 until the U-shaped claw plate 25 is tightened at the mouth of the pipe 1 .

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
