Description
Technical Field
[0001] This utility model belongs to the field of water supply and drainage technology, specifically relating to a clamping device for laying drainage pipes. Background Technology
[0002] Drainage pipelines refer to the system of pipes and channels that collect and discharge sewage, wastewater and rainwater, as well as their ancillary facilities. There are two methods for laying drainage pipelines: open excavation and pipe jacking and shield tunneling, which do not require breaking ground. The open excavation method, also known as trenching and pipe laying, is suitable for water pipes of small and medium diameters. During construction, trenches are excavated according to a fixed line and the pipes are hoisted and laid.
[0003] The existing drainage pipeline laying construction has a low level of mechanization, and the crane transfer of pipelines is slow and inefficient. When carrying out pipeline construction, the working area is often large and the distance is long, making it difficult for pipeline transportation to keep up with the construction progress. In addition, the lack of necessary pipeline fastening measures during transportation not only makes it easy to cause collisions with the pipeline wall, affecting the quality of the pipeline, but also makes it more likely that the pipeline will move in the event of sudden braking of the transport vehicle, affecting transportation safety. Utility Model Content
[0004] In view of the problems existing in the prior art, the technical solution adopted by this utility model to solve the problems existing in the prior art is as follows:
[0005] A clamping device for laying drainage pipes includes a hoisting structure, a pipe clamping structure, and a transport and fixing structure. The hoisting structure includes a transport vehicle 1, with a motor housing 2 fixedly mounted on its upper surface. An output shaft 4 of the motor housing 2 passes vertically upward through the motor housing 2. A fixed support 8 is provided on the top of the output shaft 4. A cylinder 9, a guide rod 10, and a pushing block 11 are horizontally laid on the top surface of the fixed support 8. The cylinder 9 is fixedly connected to the top surface of the fixed support 8. One end of the guide rod 10 is connected to the output shaft of the cylinder 9, and the other end is connected to the pushing block 11. Block 11 is fixedly connected, and an electric hoist 12 is fixedly installed on the outside of the pushing block 11. The bottom of the electric hoist 12 is vertically connected to a pipe clamping structure. The pipe clamping structure includes clamping blades 13. Two clamping blades 13 are arranged symmetrically at the top and bottom as a group. Bolt holes are provided on both sides of the clamping blades 13. The two clamping blades 13 clamp and fix the pipe to be lifted by fastening bolts 14 passing through the bolt holes. The transportation fixing structure includes reinforcing blades 15 symmetrically arranged at both ends of the pipe when the pipe is transported on the transport vehicle.
[0006] The motor housing 2 is equipped with a fixed shaft 3, a rotating shaft 4, a first gear 5, a second gear 6, and a first motor 7. The fixed shaft 3 is fixedly mounted on the upper end face of the transport vehicle 1. The rotating shaft 4 is rotatably connected to the fixed shaft 3 through a bearing. The rotating shaft 4 passes through the first gear 5 and is fixedly connected to the first gear 5. The first motor 7 is fixedly mounted on the transport vehicle 1. The motor shaft of the first motor 7 is fixedly connected to the second gear 6. The second gear 6 meshes with the first gear 5. When the first motor 7 is started, the motor shaft of the first motor 7 rotates, driving the second gear 6 to rotate, which in turn drives the first gear 5, which meshes with the second gear 6, to rotate. The rotation of the first gear 5 drives the rotating shaft 4, which is fixed to it, to rotate.
[0007] The inner surface of the clamping blade 13 facing the pipe to be clamped is an arc surface. When the pipe needs to be clamped and lifted, the position of the upper clamping blade 13 is adjusted by the rotating shaft 4, the pushing block 11 and the electric hoist 12 so that it cooperates with the lower clamping blade 13 set below the pipe. Then it is fixed by the fastening bolt 14. Then the electric hoist 12 is used to lift the pipe and lift it to the designated position.
[0008] The inner surface of the clamping blade 13 is provided with a rubber pad to ensure a more stable clamping effect.
[0009] A lifting ring is provided above the outer surface of the upper clamping blade 13 connected to the electric hoist 12, which cooperates with the hook below the chain of the electric hoist 12 to complete stable lifting.
[0010] The transport vehicle 1 is equipped with four movable wheels at the bottom and a pull rod on one side. The pull rod can be connected to other trailers by hooks to transport the pipes on the transport vehicle as a whole.
[0011] A check structure is fixedly installed on the transport vehicle 1 near the pull rod. The check structure includes a sliding plate 17, a fixed plate 18, and a compression spring 19. The fixed plate 18 is fixedly installed on the upper surface of the transport vehicle 1 near the pull rod. The sliding plate 17 is installed on the transport vehicle 1 away from the pull rod relative to the fixed plate 18. The sliding plate 17 is connected to the fixed plate 18 through several compression springs 19. When the sliding plate 17 is squeezed, it will move towards the fixed plate 18. The compression springs 19 buffer this movement. By installing a check structure at one end of the pipeline, the inertia of the pipeline sliding forward can be effectively buffered when the transport vehicle suddenly stops moving forward.
[0012] The reinforcing blades 15 are installed at both ends of the pipe mounted on the transport vehicle 1. Two reinforcing blades 15 are symmetrically arranged to form a set of fixing structures. Bolt holes are symmetrically arranged on both sides of the reinforcing blades 15. The pipe is fixed by fastening bolts passing through the bolt holes on both sides of the symmetrically arranged reinforcing blades 15. Two sets of fixing structures are symmetrically arranged at both ends of each pipe mounted on the transport vehicle 1. The pipe is placed on the transport vehicle for transportation through the transport fixing structure.
[0013] The reinforcing blade 15 includes a horizontal support plate 20 and a clamping blade. The clamping blade has an arched arc surface in the middle and horizontal wing plates on both sides. The horizontal support plate 20 is fixedly installed on the top of the outer side of the arched arc surface on the clamping blade. Bolt holes are symmetrically arranged on the horizontal wing plates. A rubber gasket 16 is provided on the inner side of the arc surface of the clamping blade. After the pipe is fixed by the two sets of reinforcing blades 15 at both ends, the horizontal support plate 20 on the reinforcing blade 15 allows the pipe to be stably placed on the transport vehicle, and the pipes can be stacked on top of each other on the transport vehicle.
[0014] The horizontal support plate 20 is connected to the clamping blade, the fixed shaft 3 is connected to the transport vehicle 1, and the fixed support 8 is connected to the rotating shaft 4 by welding.
[0015] This utility model has the following advantages:
[0016] This utility model device includes a hoisting structure, a clamping structure, and a transport and fixing structure. The hoisting structure is driven by a motor to rotate a gear, which in turn drives a rotating shaft, thereby rotating the entire hoisting structure. A cylinder drives a guide rod, which in turn moves the pipe along the axial direction of the guide rod. An electric hoist drives a wire rope to extend and retract, thereby moving the pipe vertically. Horizontal support plates on the reinforced blades prevent the pipe from rolling and allow for stacking. A check valve structure is installed at the front of the transport vehicle. Through the buffering effect of a compression spring, it prevents the pipe from shifting inertial direction along the vehicle's travel direction during transport, such as during sudden braking, thus ensuring transport safety. Based on the structure of this utility model device, stable hoisting of pipes can be achieved, preventing pipe wall collisions during transport and ensuring stable placement and transfer of the pipes.

[0022] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings, such as... Figure 1-4 As shown, a clamping device for laying drainage pipes includes a hoisting structure, a transport fixing structure, and a pipe clamping structure. The hoisting structure includes a transport vehicle 1 with four moving wheels at the bottom. A pull rod is provided on one side of the transport vehicle 1, which can be connected to other trailers via hooks to transport the pipes on the transport vehicle as a whole. A motor box 2 is fixedly installed on the upper surface of the transport vehicle 1. The motor box 2 contains a fixed shaft 3, a rotating shaft 4, a first gear 5, a second gear 6, and a first motor 7. The fixed shaft 3 is fixedly installed on the upper surface of the transport vehicle 1. The rotating shaft 4 is rotatably connected to the fixed shaft 3 via bearings. The rotating shaft 4 passes through the first gear 5 and is fixedly connected to the first gear 5. The first motor 7 is fixedly installed on the transport vehicle 1. The motor shaft of the first motor 7 is fixedly connected to the second gear 6. The second gear 6 meshes with the first gear 5. By starting the first motor 7, the motor shaft of the first motor 7 rotates, driving the second gear 6 to rotate, which in turn drives the first gear 5 meshing with the second gear 6 to rotate. The rotation of the first gear 5 drives the rotating shaft 4 fixed to it to rotate. The output shaft 4 of the motor housing 2 passes vertically upward through the motor housing 2. A fixed support 8 is fixedly installed on the top of the output shaft 4. A cylinder 9, a guide rod 10, and a push block 11 are horizontally laid on the top surface of the fixed support 8. The cylinder 9 is fixedly connected to the top surface of the fixed support 8. The reciprocating motion of the cylinder 9 is controlled by a solenoid valve. One end of the guide rod 10 is connected to the cylinder 9, and the other end is connected to the push block 11. An electric hoist 12 is fixedly installed on the outside of the push block 11. A pipe clamping structure is vertically connected to the bottom of the electric hoist 12.
[0023] The pipe clamping structure includes clamping blades 13. Two clamping blades 13 arranged symmetrically at the top and bottom form a group. Fastening bolts 14 are provided on both sides of the clamping blades 13, and the pipe is fixed to the two clamping blades 13 by the fastening bolts 14. The inner surface of the clamping blades 13 facing the pipe to be clamped is an arc surface. When the pipe needs to be clamped and lifted, the position of the upper clamping blade 13 is adjusted using the rotating shaft 4, the pushing block 11, and the electric hoist 12, so that it mates with the lower clamping blade 13 located below the pipe. It is then fixed by the fastening bolts 14, and the electric hoist 12 is used to lift the pipe and lift it to the designated position. A rubber gasket 16 is provided on the inner surface of the clamping blades 13 facing the pipe wall. By providing the rubber gasket 16, the contact area between the pipe and the clamping equipment is increased, improving the stability of the pipe during lifting and preventing the pipe from falling off the clamping structure.
[0024] The transport fixing structure includes reinforcing blades 15, which are mounted on the transport vehicle 1. Two reinforcing blades 15 are symmetrically arranged vertically to form a fixing structure. Bolt holes are symmetrically arranged on both sides of the reinforcing blades 15. The symmetrically arranged reinforcing blades 15 fix the pipes by fastening bolts passing through the bolt holes on both sides. Two sets of fixing structures are symmetrically arranged at both ends of each pipe. The pipes are transported by placing them on the transport vehicle through the transport fixing structure. This fixing method can store and fix the pipes separately, preventing the pipes from moving arbitrarily on the transport vehicle 1, and avoiding contact and damage between the pipes, which would affect the quality of the pipes.
[0025] The reinforcing blade 15 includes a horizontal support plate 20 and a clamping blade. The clamping blade has an arched arc surface in the middle and horizontal wing plates on both sides. The horizontal support plate 20 is fixedly installed on the top of the outer side of the arched arc surface on the clamping blade. Bolt holes are symmetrically arranged on the horizontal wing plates. A rubber gasket 16 is provided on the inner side of the arc surface of the clamping blade. After the pipe is fixed by the two sets of reinforcing blades 15 at both ends, the horizontal support plate 20 on the reinforcing blade 15 allows the pipe to be stably placed on the transport vehicle, and the pipes can be stacked on top of each other on the transport vehicle.
[0026] A check structure is fixedly installed on the transport vehicle 1 near the pull rod. The check structure includes a sliding plate 17, a fixed plate 18, and a compression spring 19. The fixed plate 18 is fixedly installed on the upper surface of the transport vehicle 1 near the pull rod. The sliding plate 17 is installed on the transport vehicle 1 away from the pull rod relative to the fixed plate 18. The sliding plate 17 is connected to the fixed plate 18 through several compression springs 19. When the sliding plate 17 is squeezed, it will move towards the fixed plate 18. The compression springs 19 buffer this movement. By installing a check structure at one end of the pipeline, the inertia of the pipeline sliding forward can be effectively buffered when the transport vehicle suddenly stops moving forward.
[0027] The horizontal support plate 20 is connected to the clamping blade, the fixed shaft 3 is connected to the transport vehicle 1, and the fixed support 8 is connected to the rotating shaft 4 by welding. All of the above structures are load-bearing structures. Welding can improve the connection strength between the objects and improve the structural stability.
[0028] The workflow of this utility model is as follows:
[0029] In operation, the pipe to be transported is first hoisted onto the transport vehicle. The first motor 7 is driven, which in turn drives the second gear 6 to rotate. The first gear 5 and the second gear 6 mesh with each other. The rotation of the first gear 5 drives the rotating shaft 4 to rotate, thereby driving the cylinder 9 to rotate. The cylinder 9 drives the guide rod 10 to extend or retract, so that the electric hoist 12 is positioned directly above the pipe to be transported. The electric hoist 12 is then driven to lower the hook to the middle section of the pipe to be transported, and the hook is engaged with the lifting ring on the upper clamping blade 13. After the pipe is clamped and fixed by the lower clamping blade 13 and the upper clamping blade 13, the electric hoist 12 is retracted, which lifts the pipe in the pipe clamping structure. The cylinder 9 then drives the guide rod 10 to extend or retract. The extension and retraction of rod 10 drives the first motor 7 to rotate the clamping device to the storage position of the pipeline on the transport vehicle 1. After the electric hoist 12 lowers the pipeline to a suitable height, reinforcing blades 15 are installed at both ends of the pipeline. Then the pipeline is placed on the transport vehicle, and the pipeline clamping structure is disassembled. Since the reinforcing blades 15 have horizontal support plates 20, the pipelines can be stacked. When transporting the pipeline, the anti-return structure buffers the inertial force of the pipeline forward during sudden braking. When the transport vehicle moves to the construction position, the pipeline clamping structure is used to lift the pipeline from the transport vehicle to the laying position. Then the reinforcing blades 15 at both ends of the pipeline are removed, and the above lifting process is repeated to lift all the pipelines to the construction position.
[0030] The scope of protection of this utility model is not limited to the above-described embodiments. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its scope and spirit. If these modifications and variations fall within the scope of the claims of this utility model and their equivalents, then the intent of this utility model also includes these modifications and variations.
