Description

Technical Field

[0001] This utility model belongs to the field of pipeline engineering technology, specifically relating to a pipe-lifting device used in pipeline engineering. Background Technology

[0002] In the construction process, pipelines are facilities that use cement pipes arranged and combined to form a pipeline system. Pipeline construction is an important part of construction. For the transportation and arrangement of cement pipes, tower cranes or cranes are often used for transportation and assembly. During the use of tower cranes and cranes, cement pipes need to be clamped and fixed. The most common existing cement pipe clamping and fixing equipment is the hook; the hook is a device used to lift and pull cement pipes during the construction process, and it is widely used in the field of object transportation.

[0003] For example, CN 221274992 U discloses a pipe-lifting device for pipeline construction. This device can support an adjusting device via a support device. During this process, a drive device is activated to slide and adjust the angle of the adjusting device, and a sliding device is activated to clamp the cement pipe via a clamping mechanism. This improves the adjustability of the device, thereby increasing its working efficiency and practicality. The device includes a lifting rope and a lifting device. The lifting device is evenly installed on the lifting rope. The lifting device also includes a support device, an adjusting device, a drive device, a sliding device, and a clamping mechanism. Both the support device and the adjusting device have multiple sets of through holes. The lifting rope passes through these through holes and is fixedly fitted to the support device and the adjusting device. The connecting ends of the multiple drive devices are respectively connected to the front and rear ends of the adjusting device. The adjusting device has an installation groove, and the sliding device passes through the installation groove and slides through the adjusting device.

[0004] In the above case, the pipe is fixed from the inside by two expanding clamping mechanisms during actual use. However, the force application points of the two expanding clamping mechanisms can easily damage the cement pipe, resulting in certain defects in the equipment. Therefore, this utility model provides a pipe-lifting device for pipeline engineering. Utility Model Content

[0005] The purpose of this utility model is to provide a pipe-lifting device for pipeline engineering to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pipe-laying device for pipeline engineering, comprising a top plate, a side frame fixedly connected to one end of the top plate, a connecting plate fixedly connected to the side frame on the bottom surface of the top plate, a connecting bracket fixedly connected to the connecting plate on the bottom surface of the top plate, and four annularly distributed limiting members slidably connected to the connecting plate on the side facing the connecting bracket.

[0007] In a preferred embodiment, the top of the top plate is symmetrically fixedly connected to two inverted "L"-shaped connectors.

[0008] In a preferred embodiment, four annularly spaced guide grooves are provided on one side of the connecting plate, and a guide post is fixedly connected inside each guide groove.

[0009] In a preferred embodiment, the limiting member includes a sliding frame slidably connected to the outside of the guide post, and an arc-shaped elongated plate-like support portion is fixedly connected to the sliding frame on the opposite side of the connecting plate.

[0010] In a preferred embodiment, a triangular frame is fixedly connected between one side of the sliding frame and the bottom of the sliding frame, a drive motor is fixedly connected to one side of the connecting plate, a drive screw is fixedly connected to the output shaft of the drive motor, a threaded sleeve is threaded to the external thread of the drive screw, and the other end of the drive screw is rotatably connected to the internal part of the other end of the connecting frame.

[0011] In a preferred embodiment, the threaded sleeve is externally rotatably connected to four equidistant first connecting rods, the other end of each first connecting rod being rotatably connected to the bottom of a support in the same direction, and each tripod having a second connecting rod rotatably connected to both sides, the other end of every two second connecting rods being rotatably connected to the other end of a connecting frame.

[0012] In a preferred embodiment, each of the support portions has a deformation cavity inside, and each support portion has multiple friction protrusions on the surface that contacts the inner wall of the pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This pipe-lifting equipment used in pipeline engineering achieves a circumferential expansion and fixation of the pipeline by setting limiting components. This method not only applies force evenly, but also increases the contact area between the support and the inner wall of the pipeline, reducing the pressure per unit area and effectively protecting the pipeline from damage.

[0015] This pipe-lifting equipment for pipeline engineering is connected to the connecting frame via a triangular frame and a second connecting rod, forming a stable quadrilateral structure. This enhances the stability and load-bearing capacity of the clamping mechanism. At the same time, due to the design of the drive motor and threaded sleeve, the clamping mechanism can be flexibly adjusted according to the size and shape of the pipe, improving the applicability and work efficiency of the equipment.

[0016] The pipe-lifting equipment used in pipeline engineering features a deformation cavity and friction protrusion design inside the support section, which further enhances the friction between the clamping mechanism and the pipe, preventing the pipe from slipping or shaking during lifting and ensuring the safe progress of construction.

Detailed Implementation

[0021] The present invention will be further described below with reference to the embodiments.

[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] Please see Figure 1-3This utility model provides a pipe-laying device for pipeline engineering, including a top plate 1. A side frame 3 is fixedly connected to one end of the top plate 1. A connecting plate 4 is fixedly connected to the side frame 3 on the bottom surface of the top plate 1. A connecting bracket 6 is fixedly connected to the connecting plate 4 on the bottom surface of the top plate 1. Four annularly distributed limiting members 7 are slidably connected to the connecting plate 4 facing the connecting bracket 6. Two inverted "L"-shaped connecting members 2 are symmetrically fixedly connected to the top of the top plate 1. Four annularly distributed guide grooves 401 are opened on one side of the connecting plate 4, and a guide post 402 is fixedly connected inside each guide groove 401. The limiting member 7 includes a sliding bracket 701 slidably connected to the outside of the guide post 402. The sliding bracket 701 faces the opposite side of the connecting plate 4. An arc-shaped long plate-shaped support part 703 is fixedly connected to the top. A triangular frame 702 is fixedly connected between one side of the sliding frame 701 and the bottom of the sliding frame 701. A drive motor 5 is fixedly connected to one side of the connecting plate 4. A drive screw 8 is fixedly connected to the output shaft of the drive motor 5. A threaded sleeve 9 is threadedly connected to the outside of the drive screw 8. The other end of the drive screw 8 is rotatably connected to the inside of the other end of the connecting frame 6. The threaded sleeve 9 is rotatably connected to the outside of four equidistant first connecting rods 10. The other end of each first connecting rod 10 is rotatably connected to the bottom of the support part 703 in the same direction. A second connecting rod 11 is rotatably connected to both sides of each triangular frame 702. The other end of every two second connecting rods 11 is rotatably connected to the other end of the connecting frame 6.

[0024] In the initial state, the four limiting members 7 (through the support part 703) are evenly distributed around the center of the connecting plate 4, forming an annular space that can accommodate pipes of different diameters. When it is necessary to hoist the pipe, the pipe is first placed in the annular space formed by the four support parts 703. At this time, the inner wall of the pipe contacts the outer wall of the support part 703, providing initial support for the pipe. The drive motor 5 is started, and the output shaft of the drive motor 5 drives the drive screw 8 to rotate. Since the threaded sleeve 9 is threadedly connected to the drive screw 8, the threaded sleeve 9 will move along the axial direction of the drive screw 8. The movement of the threaded sleeve 9 is transmitted to the bottom of the support 703 through four equidistant first connecting rods 10, causing the four limiting members 7 (and their supporting members 703) to move simultaneously toward the connecting plate 4 away from the center. This movement adjusts the size of the annular space to accommodate pipes of different diameters, ensuring that the pipe is securely clamped. As the limiting members 7 move, the tripod 702 is connected to the connecting frame 6 through the second connecting rod 11. This design not only enhances the stability of the limiting members 7, but also allows the limiting members 7 to maintain a certain degree of flexibility during adjustment to accommodate minor deformations or irregular shapes of the pipe. Once the pipe is securely clamped, the top plate 1 and its connected side frames 3, connecting members 2, and other structures can be used to lift the pipe and move it to the desired position.

[0025] By adjusting the position of the limiting component 7, the pipe lifting equipment can adapt to pipes of different diameters, improving the equipment's versatility and flexibility. The four limiting components 7 are evenly distributed and adjusted synchronously, ensuring the stability of the pipe during the lifting process and reducing the safety risks caused by pipe shaking or slippage. The pipe lifting equipment has a compact and reasonable design, and the connections between the components are tight and stable, which helps to improve the overall strength and durability of the equipment.

[0026] In this embodiment, each support 703 has a deformation cavity 704 inside, and each support 703 has multiple friction protrusions 705 on the surface that contacts the inner wall of the pipe. This design allows the support 703 to deform to a certain extent when subjected to external force, thereby better conforming to the inner wall of the pipe. This deformation capability not only improves the adaptability of the equipment to pipes of different diameters and shapes, but also helps to reduce stress concentration caused by irregular or slight deformation of the pipe, thus protecting the pipe from damage. In addition, the multiple friction protrusions 705 on the surface that contacts the inner wall of the pipe increase the friction between the support 703 and the pipe, which helps to prevent the pipe from sliding or falling off during hoisting. Especially when the pipe surface is relatively smooth or wet, the friction protrusions 705 can significantly improve the safety of hoisting operations. The combination of the deformation cavity 704 and the friction protrusions 705 design can also better protect the pipe from damage and improve the safety of hoisting operations.

[0027] The working principle and usage process of this utility model are as follows: First, in the initial state, the four limiting members 7 (through the support part 703) are evenly distributed around the center of the connecting plate 4 to form an annular space that can accommodate pipes of different diameters. When it is necessary to hoist the pipe, the pipe is first placed in the annular space formed by the four support parts 703. At this time, the inner wall of the pipe is in contact with the outer wall of the support part 703, providing initial support for the pipe. The drive motor 5 is started, and the output shaft of the drive motor 5 drives the drive screw 8 to rotate. Since the threaded sleeve 9 is threadedly connected to the drive screw 8, the threaded sleeve 9 will move along the axial direction of the drive screw 8. The movement of the threaded sleeve 9 is transmitted to the bottom of the support 703 through four equidistantly distributed first connecting rods 10, causing the four limiting members 7 to move simultaneously toward the connecting plate 4 away from the center. This movement adjusts the size of the annular space to accommodate pipes of different diameters, ensuring that the pipe is securely clamped. As the limiting members 7 move, the tripod 702 is connected to the connecting frame 6 through the second connecting rod 11. This design not only enhances the stability of the limiting members 7, but also allows the limiting members 7 to maintain a certain degree of flexibility during adjustment to accommodate minor deformations or irregular shapes of the pipe. Once the pipe is securely clamped, the top plate 1 and its connected side frames 3, connecting members 2, and other structures can be used to lift the pipe and move it to the desired position.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
