Description
Technical Field
[0001] The present application relates to the technical field of pipeline handling equipment, and in particular to a pipeline handling trolley. Background Art
[0002] With the rapid development of industry and construction, the laying and maintenance of pipeline systems have become increasingly important. Pipelines are key facilities for transporting fluids, gases and other media, and handling operations are an indispensable part of their installation, maintenance and replacement. In actual operations, especially when there is a lack of lifting tools or facing a small and complex workspace, handling pipelines has become an extremely challenging task.
[0003] Currently, the transportation of pipelines in such environments mainly relies on traditional manual handling methods, building temporary support frames and using hand winches for lifting, or manually lifting the pipelines and laying multiple circular cylinders underneath to assist in movement. However, although these methods can solve the problem to a certain extent, they generally have significant problems such as low efficiency, large limitations, high safety risks, and easy damage to the ground, so they need to be improved. Utility Model Content
[0004] In order to solve the problem of low efficiency of traditional pipe transporting methods, the present application provides a pipe transporting trolley.

[0007] Due to the traditional manual handling method, building a temporary support frame and using a hand winch for lifting, or lifting the pipe by manpower and laying multiple round cylinders underneath to assist in movement, these methods can solve the problem to a certain extent, but generally have significant problems such as low efficiency, large limitations, high safety risks, and easy damage to the ground; by adopting the above technical solution, including a frame, a pulley group is installed at the bottom of the frame, the bracket and the support rod are both installed on the frame, and the clamping assembly is installed on the support rod. The clamping assembly includes a labor-saving lever, a chain, a caliper seat and a caliper block; when the pipe needs to be transported, the trolley is moved to the vicinity of the pipe to be transported, the operator first lifts the pulling part, and lowers the clamping assembly to keep the caliper block and the caliper seat horizontal and leave a certain gap, insert the thick wall part of the pipe between the caliper block and the caliper seat, press down the pulling part, and use the labor-saving lever principle to support the support rod through the sleeve of the support rod. The pipe is lifted up and the caliper block is clamped together with the caliper seat. After the pipe is lifted and a certain gap is maintained on the ground, the operator can push the frame to place the pipe above the bracket. The operator can lower the height of the clamp by lifting the pulling part to make the pipe fall on the bracket. During the transportation process, the stability and transportation direction of the vehicle body are controlled by the pulling part. Then the staff transfers the other end of the pipe by the above method to realize pipe transportation. The arrangement of the frame, support rod and clamping assembly has a simple structure, low manufacturing cost and easy operation. The labor-saving lever in the lever principle is used as a whole to easily transport the pipe. The direction can be adjusted arbitrarily during transportation with strong flexibility. At the same time, the self-tightening clamp is used to fix the pipe, which effectively reduces the possibility of the pipe falling off during transportation, reduces the occurrence of safety accidents and improves work efficiency.

[0009] By adopting the above technical solution, the clamping assembly also includes a barb and a fixing bolt; the provision of the barb and the fixing bolt helps to increase the connection strength between the chain and the labor-saving lever, reducing the loosening or falling off of the connection due to excessive force during transportation, thereby improving safety. At the same time, the use of the fixing bolt further ensures the tightness between the barb and the labor-saving lever, thereby improving the structural stability of the entire clamping assembly.
[0010] Optionally, both the caliper seat and the caliper block are provided with anti-skid patterns for preventing slipping, and the anti-skid patterns are provided on the surfaces of the caliper seat and the caliper block.
[0011] By adopting the above technical solution, anti-slip grooves are integrally formed on the caliper seat and the caliper block; through the setting of the anti-slip grooves, the contact area between the caliper seat, the caliper block surface and the pipeline can be significantly increased, thereby improving the friction force, which helps to clamp the pipeline more firmly during transportation, reduce its falling off due to sliding or vibration, and improve the safety and reliability of transportation.
[0012] Optionally, a rotating sleeve is rotatably provided on the support rod, the effort-saving lever is connected to the rotating sleeve, and the pulling part is connected to the rotating sleeve.
[0013] By adopting the above technical solution, the rotating sleeve is rotatably installed on the support rod; through the setting of the rotating sleeve, the rotating sleeve makes the rotation of the labor-saving lever more flexible, the angle and position of the labor-saving lever can be adjusted as needed, and the rotation center of the labor-saving lever can be conveniently controlled, making the force transmission smoother and more efficient.
[0014] Optionally, the pulling portion includes a connecting rod and a handle, the connecting rod is connected to the rotating sleeve, and the handle is connected to an end of the connecting rod away from the rotating sleeve.
[0015] By adopting the above technical solution, the pulling part includes a connecting rod and a handle, the connecting rod is welded and fixed to the rotating sleeve, and the handle is welded and fixed to the connecting rod; through the setting of the connecting rod and the handle, the connecting rod serves as a bridge connecting the rotating sleeve and the handle, which can effectively transmit the force applied by the operator to the handle to the rotating sleeve, and then drive the labor-saving lever to work. At the same time, the design of the handle makes it more convenient for the operator to hold and apply force, thereby improving operating efficiency.
[0016] Optionally, the connecting rod is arranged at an end of the rotating sleeve away from the effort-saving lever, and the length of the connecting rod is greater than the length of the effort-saving lever.
[0017] By adopting the above technical solution, the length of the connecting rod is greater than the length of the force-saving lever; by setting the length of the connecting rod, the connecting rod serves as a medium for transmitting force, and its length directly determines the size of the operating lever. When the length of the connecting rod is greater than the force-saving lever, it actually increases the length of the lever when the operator applies force. According to the principle of leverage, the longer the lever arm, the smaller the force required, thereby achieving a more labor-saving operation.
[0018] Optionally, the surface of the bracket is provided with an arc-shaped surface for supporting the tube.
[0019] By adopting the above technical solution, a curved surface is opened on the surface of the bracket, and the curved surface is used to fit the outer wall of the pipeline; through the setting of the curved surface, the curved surface fits tightly with the outer wall of the pipeline, which can effectively reduce the shaking and displacement of the pipeline on the bracket, thereby improving the stability of the transport pipeline.
[0020] Optionally, the pulley assembly includes a plurality of universal wheels, and the plurality of universal wheels are sequentially connected to the bottom of the frame, and each of the universal wheels is slidably connected to the ground.

The overall lever principle is used to easily transport the pipes. The direction can be adjusted arbitrarily during transportation, which is highly flexible. At the same time, the self-tightening clamp is used to fix the pipes, which effectively reduces the possibility of the pipes falling off during transportation, reduces the occurrence of safety accidents, and improves work efficiency.
[0024] The anti-slip grooves significantly increase the contact area between the caliper seat, the caliper block surface, and the pipe, thereby increasing friction and helping to more firmly clamp the pipe during handling, reducing the risk of it falling off due to sliding or vibration, and improving handling safety and reliability.
[0025] The setting of several universal wheels greatly improves the flexibility and adaptability of the transport trolley. It can move smoothly whether on flat ground or complex terrain. The operator can easily push or pull the frame, making operation convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0029] The following is combined with Figure 1-2 This application is described in further detail.
[0030] The embodiment of the present application discloses a pipe transport trolley. Figure 1 The pipe transport trolley includes a frame 1. In this embodiment, the frame 1 adopts a triangular support structure as a whole and has good stability. A pulley set 2 is installed at the bottom of the frame 1, and a support rod 3 is welded and fixed on the frame 1. A clamping assembly 4 is installed on the support rod 3. In this embodiment, the clamping assembly 4 is used to fix the pipe wall.
[0031] Reference Figure 1 The pulley assembly 2 includes several universal wheels 21, and the plurality of universal wheels 21 are installed at the bottom of the frame 1. In this embodiment, the number of universal wheels 21 can be four, which greatly improves the flexibility and adaptability of the transport trolley. Whether on flat ground or complex terrain, it can achieve smooth movement. The operator can easily push or pull the frame 1, and the operation is convenient.
[0032] Reference Figure 1 and Figure 2 A rotating sleeve 9 is rotatably installed on the support rod 3, and the clamping assembly 4 is arranged on the rotating sleeve 9. The clamping assembly 4 includes a labor-saving lever 41, a chain 42, a caliper seat 43, a caliper block 44, a barb 45 and a fixing bolt 46. One end of the labor-saving lever 41 is welded and fixed to one end of the rotating sleeve 9, and the other end of the labor-saving lever 41 is provided with an assembly hole 7, and the barb 45 is installed at the assembly hole 7. In this embodiment, the fixing bolt 46 passes through the labor-saving lever 41 and the barb 45. The use of the fixing bolt 46 further ensures the tightness between the barb 45 and the labor-saving lever 41, thereby improving the structural stability of the entire clamping assembly 4.
[0033] Reference Figure 1 and Figure 2 One end of the chain 42 is connected to the hook head of the barb 45, and the other end of the chain 42 is connected to the end of the caliper block 44. The caliper seat 43 cooperates with the caliper block 44. The middle section of the caliper block 44 is hingedly mounted on the caliper seat 43. The surface of the caliper block 44 is arc-shaped. In this embodiment, a pipe wall area is formed between the caliper block 44 and the caliper seat 43 for fixing the pipe wall, which can transport pipes of various materials commonly used with a diameter of φ114-φ529mm and a wall thickness of 2.5-10mm.
[0034] Reference Figure 1 and Figure 2 The caliper seat 43 and the caliper block 44 are integrally formed with anti-slip grooves 8. The anti-slip grooves 8 can significantly increase the contact area between the surfaces of the caliper seat 43 and the caliper block 44 and the pipeline, thereby increasing the friction force, helping to clamp the pipeline more firmly during transportation, reducing its falling off due to sliding or vibration, and improving the safety and reliability of transportation.
[0035] Reference Figure 1, a pulling part 5 is also installed on the rotating sleeve 9. In this embodiment, the pulling part 5 is used to lift and press down the effort-saving lever 41 by rotating the sleeve 9. The pulling part 5 includes a connecting rod 51 and a handle 52. One end of the connecting rod 51 is welded and fixed to the rotating sleeve 9, and the other end of the connecting rod 51 is welded and fixed to the handle 52. The connecting rod 51 is located at the end of the rotating sleeve 9 away from the effort-saving lever 41, and the length of the connecting rod 51 is greater than the length of the effort-saving lever 41; the connecting rod 51 serves as a medium for transmitting force, and its length directly determines the size of the operating lever arm. When the length of the connecting rod 51 is greater than the effort-saving lever 41, it actually increases the length of the lever arm when the operator applies force. According to the principle of leverage, the longer the lever arm, the smaller the force required, thereby achieving a more effortless operation.
[0036] Reference Figure 1 A bracket 6 is welded and fixed on the frame 1. The bracket 6 is located below the support rod 3. The bracket 6 is used to support the pipe. In this embodiment, an arc-shaped surface 61 is provided on the surface of the bracket 6. The arc-shaped surface 61 fits tightly with the outer wall of the pipe, which can effectively reduce the shaking and displacement of the pipe on the bracket 6, thereby improving the stability of the transport pipe.
[0037] The implementation principle of a pipe transport trolley in the embodiment of the present application is as follows: when it is necessary to transport the pipe, the trolley is moved to the vicinity of the pipe to be transported, the operator first lifts the handle 52, and then the connecting rod 51 lowers the clamping assembly 4 by rotating the sleeve 9 to keep the caliper and the caliper seat 43 at the same level and maintain a certain gap. At this time, the thick wall part of the pipe can be inserted between the caliper block 44 and the caliper seat 43, and the handle 52 is pressed down. By utilizing the principle of the labor-saving lever 41, the fitting point of the rotating sleeve and the support rod 3 is used as the fulcrum, so that the entire frame 1 becomes a labor-saving lever 41 structure. By pressing down the handle 52, the pipe can be easily lifted with a lever of nearly 1:10. At this time, the chain 42 connects the labor-saving lever 41 and the caliper block 44. With the downward pressure, the caliper block 44 is pulled upward, and the caliper block 44 cooperates with the caliper The clamp seat 43 is locked, and when the pipe is lifted and a certain gap is maintained with the ground, the frame 1 is pushed toward the pipe when the pipe is lifted, so that the pipe is above the bracket 6. The operator can lower the height of the clamp by lifting the handle 52 to make the pipe fall on the bracket 6. During the transportation process, the stability and transportation direction of the vehicle body are controlled by the pulling part 5. Then the staff transfers the other end of the pipe through the above method to realize the transportation of the pipe. Through the arrangement of the frame 1, the support rod 3 and the clamping assembly 4, the structure is simple, the manufacturing cost is low, and the operation is convenient. The overall use of the labor-saving lever 41 in the lever principle can easily transport the pipe. The direction can be adjusted arbitrarily during transportation and has strong flexibility. At the same time, the self-tightening clamp is used to fix the pipe, which effectively reduces the possibility of the pipe falling off during transportation, reduces the occurrence of safety accidents, and improves work efficiency.
[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
