Description

Technical Field

[0001] This utility model relates to the field of pipeline engineering technology, and in particular to an auxiliary positioning and hoisting device for pipeline laying. Background Technology

[0002] Pipeline laying auxiliary positioning and hoisting equipment is used to achieve efficient hoisting and reduce the intensity of manual labor. This equipment can improve the construction quality and efficiency of pipeline laying, reduce errors and safety hazards, ensure the smooth progress of projects, lower construction costs, and better adapt to complex construction environments, providing strong support for the construction of various pipeline projects.

[0003] Pipeline laying auxiliary positioning and hoisting equipment mainly uses a power unit to drive a winch or hydraulic system, causing the lifting arm to rise, rotate, and move ropes to lift and precisely position the pipeline. It is suitable for various pipeline projects, such as urban water supply and drainage, gas, and heating pipeline laying, as well as pipeline installation in industrial plants. It can efficiently and safely complete the lifting and installation of pipelines, improving construction efficiency and reducing labor intensity.

[0004] In existing technologies, some hoisting equipment typically lifts pipes by telescopic movement. However, when hoisting pipes with ropes, the horizontal positioning of the pipes is not accurate enough, which can easily lead to swaying or displacement. Furthermore, the connection points between the ropes and the pipes are relatively few and easily loosened by external forces. During hoisting and movement, the pipes are prone to slipping and causing damage. Therefore, an auxiliary positioning hoisting device for pipe laying is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an auxiliary positioning and hoisting device for pipeline laying, which aims to improve the problems in the prior art where the horizontal positioning of the pipeline is not accurate enough when the pipeline is hoisted by ropes, and it is easy to sway or deviate. In addition, there are relatively few connection points between the rope and the pipeline, and the rope is easily loosened by external forces. The pipeline is prone to slipping and causing damage during the hoisting and moving process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An auxiliary positioning and hoisting device for pipeline laying includes a base frame and a hanger. A connecting plate is slidably connected to the bottom of the hanger, and a fixing plate is fixedly connected to the bottom of the connecting plate. A cylinder is fixedly connected to the inner wall of the fixing plate, and a horizontal plate is fixedly connected to the driving end of the cylinder. Two grippers are rotatably connected to the inner wall of the fixing plate. A pitch-changing component for pitch adjustment is installed on the inner wall of the hanger, and a support component for supporting the hoisting device is fixedly connected to the top of the base frame.

[0008] As a further description of the above technical solution:

[0009] The variable pitch assembly includes a motor, the outer wall of which is fixedly connected to the inner wall of the hanger. Two transmission wheels are rotatably connected to the inner wall of the hanger. The drive end of the motor is fixedly connected to the outer wall of one of the transmission wheels. A synchronous belt is coupled to the outer wall of the transmission wheel.

[0010] As a further description of the above technical solution:

[0011] A fixing block is fixedly connected to the outer wall of the synchronous belt, and a connecting plate is fixedly connected to the bottom of the fixing block;

[0012] As a further description of the above technical solution:

[0013] The inner wall of the gripper is provided with a sliding groove, and the outer wall of the cross plate is slidably connected to the inner wall of the sliding groove.

[0014] As a further description of the above technical solution:

[0015] The support assembly includes a bracket, the outer wall of which is fixedly connected to the inner side of the base frame, and the other end of the bracket is fixedly connected to a column;

[0016] As a further description of the above technical solution:

[0017] A hydraulic rod is fixedly connected to the outer wall of the column, and a hydraulic arm is fixedly connected to the drive end of the hydraulic rod.

[0018] As a further description of the above technical solution:

[0019] The left end of the hydraulic arm is fixedly connected to the top of the column, and the bottom of the hydraulic arm is fixedly connected to a hook.

[0020] As a further description of the above technical solution:

[0021] The bottom of the hook is detachably connected to a lifting chain, and the bottom of the lifting chain is fixedly connected to a hanger.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the cylinder starts and retracts, causing the horizontal plate to move upward. The upward movement of the horizontal plate causes the sliding groove opened on the inner wall of the gripper to move, thereby causing the gripper to grip the pipe inward and fix the pipe. Then the hydraulic rod extends again, causing the hydraulic arm to move upward, so that the pipe can be lifted. Compared with telescopic lifting, it can better fix the position of the pipe and will not cause the pipe to shake during the transportation process, thus not affecting the subsequent positioning and installation.

[0024] 2. In this utility model, the starting of the motor drives the transmission wheel to rotate, and the rotation of the transmission wheel drives the synchronous belt to start moving, thereby causing the fixed blocks fixedly connected on both sides of the synchronous belt to start moving towards or in opposite directions, thus causing the synchronous belt to drive the hoisting components at its bottom to move towards or in opposite directions, so as to adapt to different pipe lengths.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 2 to 4This utility model provides an embodiment of an auxiliary positioning and hoisting device for pipeline laying. This device is used to assist in positioning and hoisting pipelines during the pipeline laying process, which can improve the efficiency and accuracy of pipeline laying. It includes a base frame 1 and a hanger 2. The base frame 1 serves as the basic support structure of the entire device, which can ensure the stability of the device during operation. The hanger 2 is used to hang the pipeline for hoisting operations. A connecting plate 6 is slidably connected to the bottom of the hanger 2. The connecting plate 6 can slide flexibly at the bottom of the hanger 2, which is convenient for adjusting the position to adapt to different hoisting requirements. A fixing plate 7 is fixedly connected to the bottom of the connecting plate 6. The fixing plate 7 is used to install and fix other components, providing a stable foundation for subsequent operations.

[0033] A cylinder 8 is fixedly connected to the inner wall of the fixed plate 7. The cylinder 8 serves as a power source, providing power for the subsequent clamping action of the gripper 9. A horizontal plate 11 is fixedly connected to the drive end of the cylinder 8. The horizontal plate 11 can move under the drive of the cylinder 8, thereby driving the gripper 9 to move. Two grippers 9 are rotatably connected to the inner wall of the fixed plate 7. The grippers 9 are used to clamp the pipe and fix it, facilitating subsequent hoisting. A pitch-changing component for pitch adjustment is installed on the inner wall of the hanger 2. The pitch-changing component can adjust the spacing of the hoisting components according to the pipe length, improving the adaptability of the equipment to pipes of different lengths. A support component for supporting the hoisting equipment is fixedly connected to the top of the base frame 1. The support component can provide stable support for the entire hoisting equipment and ensure the safety of the hoisting process. A sliding groove 10 is opened on the inner wall of the gripper 9. The sliding groove 10 provides a track for the movement of the horizontal plate 11, making the movement of the horizontal plate 11 more stable and accurate. The outer wall of the horizontal plate 11 is slidably connected to the inner wall of the sliding groove 10.

[0034] Reference Figure 1 , Figure 3 and Figure 4 The pitch-changing assembly includes a motor 3, which serves as the power source for the pitch-changing assembly and provides power for the rotation of the transmission wheel 18. The outer wall of the motor 3 is fixedly connected to the inner wall of the hanger 2 to ensure the stability of the motor 3 installation. Two transmission wheels 18 are rotatably connected to the inner wall of the hanger 2. The transmission wheels 18 are used to drive the synchronous belt 5 to move, thereby realizing the pitch-changing function. The drive end of the motor 3 is fixedly connected to the outer wall of one of the transmission wheels 18, so that the motor 3 can directly drive the transmission wheel 18 to rotate. The outer wall of the transmission wheel 18 is coupled with the synchronous belt 5, which can move under the drive of the transmission wheel 18, thereby realizing the pitch-changing function. The outer wall of the synchronous belt 5 is fixedly connected with a fixing block 4, which is used to connect the synchronous belt 5 and the connecting plate 6, so that the movement of the synchronous belt 5 can drive the movement of the connecting plate 6.

[0035] A connecting plate 6 is fixedly connected to the bottom of the fixing block 4. The connecting plate 6 can move under the drive of the synchronous belt 5, thereby adjusting the spacing of the lifting components. The support components include a bracket 12, which supports the column 13 and enhances the stability of the entire support structure. The outer wall of the bracket 12 is fixedly connected to the inner side of the base frame 1 to ensure the firmness of the bracket 12 installation. The other end of the bracket 12 is fixedly connected to the column 13. The column 13, as the main part of the support structure, provides support for the hydraulic rod 14 and the hydraulic arm 15. The outer wall of the column 13 is fixedly connected to the hydraulic rod 14, which serves as a power source and can drive the hydraulic arm 15 to move up and down to realize the lifting of the pipeline. The hydraulic arm 15 is fixedly connected to the drive end of the hydraulic rod 14. The hydraulic arm 15 moves under the drive of the hydraulic rod 14, thereby driving the hook 16 and the chain 17 to move. The left end of the hydraulic arm 15 is fixedly connected to the top of the column 13 to ensure the stability of the hydraulic arm 15 connection. The bottom of the hydraulic arm 15 is fixedly connected to the hook 16, which is used to hang the chain 17 to realize the lifting of the pipeline. The bottom of the hook 16 is detachably connected to the chain 17. The chain 17 can be disassembled and replaced according to actual needs for convenient use. The bottom of the chain 17 is fixedly connected to the hanger 2, which is connected to the hook 16 through the chain 17 to realize the lifting of the pipeline.

[0036] Working principle: When it is necessary to lift the pipe to be installed, the hydraulic rod 14 is activated and retracted, driving the hydraulic arm 15 to move downward. The downward movement of the hydraulic arm 15 drives the hook 16 and the chain 17 to move downward, thereby causing the hanger 2 to move downward. When the pipe to be lifted is between the two grippers 9, the cylinder 8 is activated and retracted, driving the horizontal plate 11 to move upward. The upward movement of the horizontal plate 11 causes the sliding groove 10 opened on the inner wall of the gripper 9 to move, thereby causing the gripper 9 to clamp the pipe inward to fix the pipe. Then the hydraulic rod 14 extends again, driving the hydraulic arm 15 to move upward, so that the pipe can be lifted. At this time, by moving the base frame 1, the pipe can be moved to the required installation scene for installation. The bracket 12 provides support for the column 13. The hydraulic arm 15 can be extended and retracted to better clamp the pipe at the designated position.

[0037] When lifting pipes, since the pipes vary in length, it is necessary to adapt to different pipe lengths. At this time, motor 3 starts, which drives the transmission wheel 18 to rotate. The rotation of the transmission wheel 18 drives the synchronous belt 5 to start moving, so that the fixed blocks 4 fixedly connected to both sides of the synchronous belt 5 start to move in opposite directions. This causes the synchronous belt 5 to drive the lifting components at its bottom to move in opposite directions, thereby adapting to different pipe lengths, improving the flexibility of the equipment, adapting to different working conditions, and thus improving work efficiency.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
