Description

Technical Field

[0001] This utility model relates to the field of pipe clamp technology, and in particular to a pressure-bearing pipe clamp for pump truck delivery pipes. Background Technology

[0002] The pump truck's delivery pipe is a core component of the concrete pump truck. During the operation of the pump truck, the delivery pipe needs to be spliced ​​together in multiple sections to form a continuous delivery channel, and the pipe clamp is the core component to ensure that the connection of each section of the pipe is firm and the sealing is reliable.

[0003] Currently, the existing pump truck delivery pipe clamps are usually relatively fixed in structure. Not only is it difficult to flexibly and accurately adjust the overall clamping size when facing delivery pipes of different sizes, but they can also only be adapted to pump truck delivery pipes of limited specifications. Furthermore, the clamping force cannot be adjusted according to actual needs, resulting in the pipe clamp and delivery pipe not fitting tightly and being firmly connected. This can easily lead to loosening and leakage during concrete delivery. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, which not only makes it difficult to adapt to different sizes of conveying pipes, but also cannot adjust the clamping force according to actual needs, resulting in reduced adaptability and reliability of pipe clamps. Therefore, a pressure-bearing pipe clamp for pump truck conveying pipes is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pressure-bearing pipe clamp for pump truck delivery pipes, comprising:

[0007] Pipe clamp one and pipe clamp two, each with a placement groove one on its rear side and a placement groove two on its front side;

[0008] The first and second pipe clamps are equipped with an adjustment component, which is used to adjust the overall clamping size and clamping force of the pipe clamps according to the different sizes of the conveying pipes.

[0009] In one possible design, the adjusting assembly includes a rotating column 1 rotatably disposed inside the placement slots 1 of pipe clamp 1 and pipe clamp 2, respectively. The same bidirectional lead screw is threaded through the two rotating columns 1. The two rotating columns 1 are threaded to different threaded ends of the bidirectional lead screw. Nuts are fixedly disposed at both ends of the bidirectional lead screw. Limiting holes 1 are provided on one side of both the bidirectional lead screw and the two rotating columns 1.

[0010] In one possible design, the adjusting assembly further includes a rotating column two rotatably disposed inside the placement slot two of the pipe clamp two. A screw is fixedly disposed on one side of the rotating column two, and a limit block is fixedly disposed at one end of the screw. A clamp is threadedly connected to the external thread of the screw. A step is provided inside the placement slot two of the pipe clamp one. The clamp can disengage and engage with the step inside the placement slot two. A nut is threadedly connected to the external thread of the screw. The nut is rotatably connected to the clamp.

[0011] In one possible design, a pressure handle is hinged to the opening side of the placement slot 2 of the pipe clamp 1, and a pin is threaded through one side of the pressure handle. A knob is fixedly installed at the outer end of the pin. Limiting holes 2 are opened on the outer rings of the screw and the card holder, and the pin can be disengaged and inserted into the limiting holes 2 of the screw and the card holder.

[0012] In one possible design, a buckle block is fixedly provided on one side of the pipe clamp, and a buckle frame is fixedly provided on one side of the pressure handle. The buckle frame is adapted to the buckle block and can be disengaged from it.

[0013] In one possible design, rubber pads are fixedly installed on the inner sides of both pipe clamp one and pipe clamp two.

[0014] In this application, before using the pressure-type pipe clamp, a comprehensive inspection of the pipe clamp is required to check for damage. When connecting the pump truck's delivery pipe, pipe clamp one and pipe clamp two are placed on both sides of the connection point of the pump truck's delivery pipe, so that the connection point of the two delivery pipes is located between pipe clamp one and pipe clamp two. Then, according to the size of the delivery pipe, the nut is rotated. Since the two rotating pins one are threaded to different threads at both ends of the double-acting screw, when the nut is rotated, the double-acting screw will rotate, thereby causing the two rotating pins one to move closer or further apart. As the rotating pins one move, pipe clamp one and pipe clamp two will also move closer or further apart accordingly, thereby adjusting the overall clamping size of the pipe clamp to accommodate delivery pipes of different sizes. After adjusting to the appropriate position, stop. Use the anti-rotation nut (when ending the rotation of the nut, ensure that the first limiting hole on the rotating column is aligned with the first limiting hole on the double-acting screw), then rotate the clamp outside the screw. The clamp will move along the screw, moving the clamp to the step inside the slot 2 of the pipe clamp. Move the screw through the rotating column 2 so that the clamp on the screw is engaged in the step (at this time, ensure that the second limiting hole on the clamp is aligned with the second limiting hole on the screw). This achieves initial closure of the openings of pipe clamp 1 and pipe clamp 2. Then rotate the nut in the opposite direction. When the nut rotates, it presses against pipe clamp 1. At this time, the screw pulls pipe clamp 2, causing the opening ends of pipe clamp 1 and pipe clamp 2 to move towards each other, thereby further adjusting the clamping degree of the clamp and ensuring that pipe clamp 1 and pipe clamp 2 are tightly connected.

[0015] When clamping the connection between the two conveying pipes with pipe clamp one and pipe clamp two, rotate the pressure handle towards pipe clamp two, gradually bringing the pressure handle closer to pipe clamp two. When the pressure handle is rotated to the appropriate position (close to pipe clamp two), the buckle on the pressure handle contacts the buckle block on pipe clamp one and engages with the buckle block through the buckle groove on the buckle. Then rotate the knob. When the knob rotates, it drives the pin to move towards the clamp on the pressure handle. As the pin moves towards the clamp, the pin slowly inserts into the limiting hole two of the screw and the clamp, thereby fixing the position of the clamp on the screw. Then, use the cotter pin to insert into the limiting hole one on the rotating column one and the double-acting screw, thereby fixing the position of the rotating column one on the double-acting screw, completing the final locking of the pipe clamp, ensuring that the pipe clamp firmly clamps the pump truck conveying pipe, and ensuring that the vibration that occurs during the transportation of concrete through the conveying pipeline will not loosen the position of the rotating column one on the double-acting screw or the clamp on the screw.

[0016] This utility model has the following beneficial effects:

[0017] By adjusting the components, this invention not only allows for flexible adjustment of the overall clamping size of the pipe clamp according to different sizes of conveying pipes to adapt to pump truck conveying pipes of different specifications, but also allows for adjustment of the clamping force to ensure that the pipe clamp and the conveying pipe are tightly fitted and securely connected, effectively avoiding problems such as loosening and leakage during the conveying process, and comprehensively improving the adaptability and reliability of the pipe clamp.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In one embodiment

[0025] Reference Figure 1-4 A pipe clamp, comprising:

[0026] The components include pipe clamp 1, pipe clamp 2, and adjustment components. Both pipe clamp 1 and pipe clamp 2 have a placement groove 3 on their rear side and a placement groove 8 on their front side. A rubber pad 20 is also fixedly installed inside the groove. The rubber pad 20 is soft and elastic, which can buffer and seal when the pipe clamp clamps the conveying pipe to prevent the conveying pipe from being damaged by excessive compression and to prevent concrete leakage during the conveying process.

[0027] The adjustment assembly is used to adjust the overall clamping size and clamping force of the pipe clamp according to different sizes of conveying pipes. It includes rotating posts 4 rotatably mounted inside the placement slots 3 of pipe clamp 1 and pipe clamp 2, respectively. A single double-acting screw 5 is threaded through both rotating posts 4, and each rotating post 4 is threaded to different threads at both ends of the double-acting screw 5. Nuts 6 are fixedly installed at both ends of the double-acting screw 5 to facilitate rotation by the operator using tools. Limit holes 7 are provided on one side of both the double-acting screw 5 and the two rotating posts 4. When it is necessary to adjust the clamping size of the pipe clamp to adapt to different specifications of pump truck conveying pipes, the operator... Hold the nut 6 and rotate it. Since the threads at both ends of the double-acting screw 5 are in opposite directions, when the nut 6 is rotated, the two rotating posts 4 will move closer or further apart along the double-acting screw 5. As the rotating posts 4 move, the pipe clamps 1 and 2 will also move closer or further apart accordingly, thereby adjusting the overall clamping size of the pipe clamp. After adjusting to the appropriate position, stop rotating the nut 6 and use a cotter pin or other tool to insert into the aligned limiting hole 7 on the rotating posts 4 and the double-acting screw 5 to fix the rotating posts 4 on the double-acting screw 5. This prevents the rotating posts 4 from moving due to vibration or other reasons during subsequent use and ensures the stability of the pipe clamp size.

[0028] A rotating post 9 is rotatably installed inside the placement slot 8 of pipe clamp 2. A screw 10 is fixedly installed on one side of the rotating post 9. A limit block 14 is fixedly installed at one end of the screw 10 to prevent the clamp 11 from falling off the screw 10. The clamp 11 is threadedly connected to the outside of the screw 10. A step is provided inside the placement slot 8 of pipe clamp 1. The clamp 11 can disengage and be inserted into the step inside the placement slot 8. A nut 12 is also threadedly connected to the outside of the screw 10, and the nut 12 is fixedly connected to the clamp 11. After the pipe clamp size is adjusted, the clamping force needs to be adjusted. The operator rotates the clamp 11 outside the screw 10, and the clamp 11 will move along the screw 10. Move the screw 10 to move the bracket 11 to the step inside the slot 8 of the pipe clamp 1. Then move the screw 10 by rotating the column 9 so that the bracket 11 on the screw 10 is engaged in the step. At this time, ensure that the limiting hole 13 on the bracket 11 is aligned with the limiting hole 13 on the screw 10. Next, rotate the nut 12 in the opposite direction. When the nut 12 rotates, it will press against the pipe clamp 1. At the same time, the screw 10 will pull the pipe clamp 2, so that the open ends of the pipe clamp 1 and the pipe clamp 2 move closer to each other. This further adjusts the clamping degree of the bracket 11, ensuring that the pipe clamp 1 and the pipe clamp 2 are tightly connected and achieve the appropriate clamping force.

[0029] This application can be used in the field of pressure-bearing pipe clamps for pump truck delivery pipes, and can also be used in other fields applicable to this application.

[0030] In another embodiment

[0031] Reference Figure 4A pressure-bearing pipe clamp for pump truck delivery pipes is described, applying the technical field of pressure-bearing pipe clamps for pump truck delivery pipes. A pressure bristle 15 is hinged to the open side of the placement groove 8 of the pipe clamp 1. The pressure bristle 15 can rotate within a certain angle range. A pin 19 is threaded through one side of the pressure bristle 15, and a knob 18 is fixedly installed at the outer end of the pin 19 for easy rotation by the operator. Limiting holes 13 are provided on the outer rings of both the screw 10 and the clamp 11, allowing the pin 19 to disengage and be inserted into these holes. After the pipe clamp 1 and the pipe clamp 2 clamp the delivery pipe, the operator rotates the pressure bristle 15 towards the pipe clamp 2, gradually bringing the pressure bristle 15 closer to the pipe clamp 2. When the pressure bristle 15 is rotated to the appropriate position, it engages with the pipe clamp 2. When clamp 2 is engaged, the buckle 17 fixed on one side of clamp 1 and the buckle 16 fixed on one side of pressure handle 15 come into contact. The buckle 16 and buckle 17 are compatible and can be disengaged. Buckle 16 and buckle 17 are engaged to achieve initial fixation of pressure handle 15. Then, rotate knob 18. When knob 18 rotates, it drives pin 19 to move on pressure handle 15 toward clamp 11. As pin 19 moves toward clamp 11, pin 19 slowly inserts into the limiting hole 2 13 of screw 10 and clamp 11, thereby fixing the position of clamp 11 on screw 10 and completing the final locking of pipe clamp. This ensures that pipe clamp firmly clamps the pump truck delivery pipe and prevents vibration from loosening the position of each component during the transportation of concrete through the delivery pipeline.
