Description

Technical Field

[0001] This utility model relates to the field of water cutting clamp technology, and in particular to a water cutting anti-deformation clamp for guardrail pipes. Background Technology

[0002] Guardrails are fence structures used for isolation, protection, or decoration. They are mainly used in roads, bridges, balconies, municipal engineering projects, and other scenarios. Their core functions include safety protection, traffic guidance, area division, and environmental beautification. Guardrail tubing is the main structural material used to make guardrails.

[0003] However, in the existing technology, the current industrial cutting technology has become the mainstream cutting method due to its low cost and ease of operation. When water jet cutting is used to cut guardrail pipes, the guardrail pipes will vibrate due to the impact of high-pressure water flow during the water jet cutting process. Since guardrail pipes are generally hollow and there is usually a lack of internal vibration damping measures when cutting them, the vibration may be amplified during the cutting process, which may cause the cut to deform. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the existing technology: during water jet cutting, the guardrail pipe will vibrate due to the impact of high-pressure water flow. Since the guardrail pipe is generally hollow and there is usually a lack of internal vibration damping measures when cutting it, the vibration may be amplified during cutting, which may cause the cut to deform.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a water-cutting anti-deformation clamp for guardrail pipes, comprising a U-shaped base, a bracket fixed to the surface of the U-shaped base, and a lower clamp fixed to the front surface of the bracket, an electric telescopic rod fixed through the top of the bracket, and an upper clamp fixed to one end of the electric telescopic rod, the guardrail pipe body being clamped between the lower clamp and the upper clamp, a fixing plate fixedly connected to both sides of the U-shaped base, and a supporting threaded pipe fixed to the upper surface of the fixing plate, a lead screw threadedly connected to the supporting threaded pipe, and a sponge vibration damping head fixedly connected to one end of the lead screw, mounting frames placed on both sides of the U-shaped base, and a motor fixedly connected to the top of the mounting frame, the output end of the motor being fixedly connected to the lead screw, a movable rod fixedly connected to one side of the mounting frame, and a connecting pipe fixedly connected to one side of the fixing plate, the movable rod being movably inserted and connected to the U-shaped base and the connecting pipe, the front end of the movable rod being on the same vertical plane as the front end of the sponge vibration damping head.

[0006] In a preferred embodiment, the size of the sponge vibration damping head is consistent with the size of the inner cross-section of the guardrail pipe body.

[0007] In a preferred embodiment, rollers are rotatably connected to both sides of the mounting bracket.

[0008] In a preferred embodiment, both the lower and upper clamps have anti-slip textures on their clamping surfaces.

[0009] In a preferred embodiment, the lower surface of the lower clamp is fixedly connected to a support leg, and the support leg is fixedly connected to the U-shaped chassis.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] This invention uses a lower clamp, an electric telescopic rod, and an upper clamp to clamp and fix the guardrail pipe body on a support, ensuring stability during water cutting. After the guardrail pipe body is fixed, a motor drives a lead screw to rotate. The lead screw, which is connected to the threaded support pipe, moves linearly while rotating, thereby sending the sponge vibration damping heads located at both ends of the guardrail pipe body into the interior of the guardrail pipe body. Then, water cutting is performed between the two sponge vibration damping heads, which dampen the vibration generated by water cutting, reducing the deformation of the guardrail pipe body at the cut point due to vibration.

[0017] 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.

[0018] Example 1

[0019] like Figure 1-3As shown, this utility model provides a technical solution: a water-cutting anti-deformation clamp for guardrail pipes, including a U-shaped base 1, a support 2 fixed to the surface of the U-shaped base 1, and a lower clamp 3 fixed to the front surface of the support 2. An electric telescopic rod 5 is fixed through the top of the support 2, and an upper clamp 6 is fixed to one end of the electric telescopic rod 5. The guardrail pipe body 7 is clamped between the lower clamp 3 and the upper clamp 6. The guardrail pipe body 7 to be cut is first placed on the surface of the lower clamp 3, and then the electric telescopic rod 5 on the support 2 is controlled to extend, causing the upper clamp 6 to move down and press against the surface of the guardrail pipe body 7, thereby clamping and fixing the guardrail pipe body 7 between the lower clamp 3 and the upper clamp 6, improving the water-cutting performance of the guardrail pipe body 7. To ensure stability, both sides of the U-shaped chassis 1 are fixedly connected to fixed plates 8, and a supporting threaded pipe 9 is fixed to the upper surface of the fixed plate 8. A screw 10 is threaded into the supporting threaded pipe 9, and a sponge vibration damping head 11 is fixedly connected to one end of the screw 10. Mounting brackets 13 are placed on both sides of the U-shaped chassis 1, and a motor 12 is fixed to the top of the mounting bracket 13. The output end of the motor 12 is fixedly connected to the screw 10. After the guardrail pipe body 7 is fixed, the motor 12 drives the screw 10 to rotate. The screw 10, which is threaded into the supporting threaded pipe 9, also moves linearly while rotating. The movement of the screw 10 drives the movement of the sponge vibration damping head 11, the motor 12, and the mounting bracket 13, so that the sponge vibration damping head... 11 is rotated and fed into the interior of the guardrail pipe body 7, so that the sponge vibration damping head 11 can play a vibration damping effect during the process of the guardrail pipe body 7 being cut by water. When a movable rod 15 is fixedly connected to one side of the mounting bracket 13, and a connecting pipe 16 is fixedly connected to one side of the fixing plate 8, and the movable rod 15 is movably inserted and connected to the U-shaped base 1 and the connecting pipe 16, the front end of the movable rod 15 is on the same vertical plane as the front end of the sponge vibration damping head 11. When the screw 10, the sponge vibration damping head 11, the motor 12 and the mounting bracket 13 move, the movable rod 15 will also move, so that it can move and insert on the U-shaped base 1 and the connecting pipe 16, thereby improving the overall straightness of the screw 10, the sponge vibration damping head 11, the motor 12 and the mounting bracket 13. The stability of the linear movement is improved, and since the front end of the movable rod 15 and the front end of the sponge vibration damping head 11 are on the same vertical plane, the position of the front end of the movable rod 15 after it has moved can, to some extent, represent the position of the sponge vibration damping head 11 inside the guardrail pipe body 7. Thus, water cutting is performed on the guardrail pipe body 7 at the gap between the movable rods 15, which can effectively avoid cutting damage to the lead screw 10 and the sponge vibration damping head 11. During the water cutting process of the guardrail pipe body 7, the sponge vibration damping head 11 is located near the water cutting point of the guardrail pipe body 7, which enables it to effectively dampen the vibration generated by the water cutting and reduce the deformation of the cut point of the guardrail pipe body 7 due to vibration.

[0020] Example 2

[0021] like Figure 1-3 As shown, the size of the sponge vibration damping head 11 is consistent with the size of the inner cross-section of the guardrail pipe body 7. This ensures that the outer surface of the sponge vibration damping head 11 can be tightly attached to the inner surface of the guardrail pipe body 7, ensuring that the sponge vibration damping head 11 provides good support and vibration damping for the interior of the guardrail pipe body 7. Rollers 14 are rotatably connected to both sides of the mounting bracket 13. When the motor 12 drives the screw 10, which is threadedly connected to the threaded pipe 9, to rotate, causing the screw 10, sponge vibration damping head 11, motor 12, and mounting bracket 13 to move, the rollers 14 assist in the movement. The rollers 14 roll when the mounting bracket 13 moves, reducing the friction generated when the mounting bracket 13 moves on the ground and improving the smoothness of the movement of the mounting bracket 13. The clamping surfaces of the lower clamp 3 and the upper clamp 6 are provided with anti-slip textures. The anti-slip textures further improve the stability of the lower clamp 3 and the upper clamp 6 when clamping and fixing the guardrail pipe body 7. The lower surface of the lower clamp 3 is fixedly connected to the support leg 4, and the support leg 4 is fixedly connected to the U-shaped base plate 1. The support leg 4 supports the lower clamp 3, improving the stability of the lower clamp 3 fixed on the bracket 2.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
