Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping device technology, and in particular to clamping devices used in pipeline production. Background Technology
[0002] There are many processes involved in pipeline manufacturing. Pipelines are classified into circular, square, rectangular, and irregularly shaped steel pipes according to their cross-sectional shape, and into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes, and composite steel pipes according to their material.
[0003] In the production of circular pipes, the circular pipes need to be fixed during the processing. Existing clamping devices have obvious defects and cannot meet the clamping requirements of pipes of different diameters. When faced with pipes of different specifications, operators have to frequently change the matching clamps. This process is not only cumbersome and time-consuming, but also requires additional costs, including the cost of purchasing clamps of various specifications and the wear and tear costs during the clamping process. Frequent clamping changes may also affect the production rhythm, leading to reduced production efficiency and further increasing production costs. In addition, frequent disassembly and assembly of clamps may affect the accuracy and stability of the clamping device, adversely affecting the pipe clamping effect and even potentially affecting the quality of pipe production.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0027] Example 1:
[0028] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a clamping device for pipe production, including a fixed frame 1. A mounting rod 2 is provided on one side of the fixed frame 1. Two sets of fixing plates 3 are fixedly connected to both sides of the bottom of the mounting rod 2 by connecting blocks. The inner walls of the two sets of fixing plates 3 are provided with first guide grooves 4. Two sets of pushing members 5 are provided on one side of the fixed frame 1. A limit component 6 is provided at the bottom of the pushing member 5. A clamping component 7 for clamping the pipe is provided between the two sets of fixing plates 3. By providing the pushing member 5, the limit component 6 can be easily pushed to move. By providing the limit component 6, the clamping component 7 can be easily limited. By providing the clamping component 7, the pipe can be easily clamped.
[0029] The limiting component 6 includes a limiting plate 61 disposed at the bottom of the pusher 5, and a slot 62 is provided at the bottom of the limiting plate 61.
[0030] By setting the electronic push rod 52, the limiting plate 61 can be easily moved. The two sets of limiting plates 61 are also connected to the two sets of fixed plates 3 by a rotating shaft, thus forming a lever. When the limiting plate 61 moves down, the slot 62 at the other end of the limiting plate 61 will rise. It is noted that the internal space of the slot 62 is larger than that of the connecting rod 71.
[0031] The clamping assembly 7 includes a connecting rod 71 that slides on the inner wall of the first guide groove 4. Multiple sets of pull plates 72 rotate on the outer side of the connecting rod 71, and multiple sets of pull plates 72 are rotatably connected to multiple sets of grippers 73 through multiple sets of rotating shafts.
[0032] By setting the connecting rod 71, it is easy to connect with multiple sets of pull plates 72. The design of multiple sets of pull plates 72 is used to drive multiple sets of clamps 73 for adjustment. By setting multiple sets of clamps 73, it is easy to clamp the pipe in a distributed manner, effectively disperse stress, and avoid local deformation of the pipe.
[0033] Example 2:
[0034] This is the second embodiment of the present invention, which is based on the previous embodiment.
[0035] Specifically, the inner wall of the gripper 73 has a rotatable guide rod 8, and the outer side of the guide rod 8 is fitted with a buckle 9. The inner walls of both sets of fixing plates 3 are provided with second guide grooves 10, and the outer side of the guide rod 8 is slidably connected to the inner wall of the second guide groove 10.
[0036] By setting multiple guide rods 8, it is convenient to connect multiple sets of grippers 73. The design of the buckle 9 is to prevent the two sets of grippers 73 on the outside of the two sets of fixing plates 3 from separating from the body. The design of the guide rods 8 is to facilitate the displacement of multiple sets of grippers 73 along the specific direction of the second guide groove 10.
[0037] Specifically, the pusher 5 includes multiple sets of fixing blocks 51 fixed to one side of the fixing frame 1, an electronic push rod 52 rotatably between two sets of fixing blocks 51, a fixing rod 53 rotatably connected to the piston rod of the electronic push rod 52 via a connecting ring, and the outer side of the fixing rod 53 rotatably connected to the inner wall of the limiting plate 61.
[0038] By setting the fixing block 51, it is easy to connect with the electronic push rod 52, which can provide support for the electronic push rod 52 and facilitate the rotation adjustment of the electronic push rod 52. By setting the electronic push rod 52, it is easy to push the connecting ring to move. The connecting ring here acts as a bridge for mechanical transmission, which facilitates the electronic push rod 52 to push the fixing rod 53 to move.
[0039] Example 3:
[0040] This is the third embodiment of the present invention, which is based on the first two embodiments.
[0041] Specifically, a mounting plate 11 is fixed to one side of the mounting bracket 1, and mounting discs 12 are fixed to the top and bottom of the mounting plate 11 by bolts. The mounting plate 11 and the two sets of mounting discs 12 are located on the outside of the mounting rod 2.
[0042] By using the mounting plate 11, mounting disc 12 and multiple sets of bolts, the connection between the fixing bracket 1 and the mounting rod 2 can be easily achieved.
[0043] Specifically, the upper end of the mounting rod 2 is fixed with a hanging plate 13 by bolts, and a hanging ring 14 is fixed at the top of the center of the hanging plate 13.
[0044] By setting bolts, the lifting plate 13 can be easily installed above the two mounting rods 2. By setting the lifting plate 13 and the lifting ring 14 together, the lifting device body can be easily moved.
[0045] Specifically, two sets of connecting frames 15 are fixed on both sides of the fixing frame 1, and a limit frame 16 is fixed at the bottom of the connecting frame 15.
[0046] By setting the connecting bracket 15, the limiting bracket 16 can be easily fixed and installed.
[0047] Specifically, the inner wall of the limiting frame 16 is provided with a U-shaped buckle 17, and the outer sides of both ends of the U-shaped buckle 17 are threaded with locking nuts 18, and the locking nuts 18 are located at the top of the limiting frame 16.
[0048] By setting the limiting bracket 16, the U-shaped buckle 17 can be easily inserted into its inner wall. The locking nut 18 is designed to drive the U-shaped buckle 17 to move, thereby making it easy to lock the pipe. The two sets of symmetrically designed U-shaped buckles 17 can provide a balancing force for the pipe and prevent the pipe from falling due to loss of balance when it is lifted.
[0049] Working principle: During operation, the operator first manually pulls up the multiple sets of symmetrically designed grippers 73, allowing them to slide along the track of the second guide groove 10. At this time, the connecting rod 71 moves up synchronously with the grippers 73 in the first guide groove 4 to a position slightly higher than the symmetrical slots 62, reserving space for subsequent limiting actions. Then, the pipe to be clamped is placed within the area surrounded by the grippers 73, and the electronic push rod 52 is activated. Its telescopic end pushes the connecting ring down, causing the limiting plates 61 on both sides to rotate around the axis of the fixed plate 3. Because the limiting plate 61 adopts a lever design, when one end is pressed down, the other end tilts up, and the slot 62 on the tilted end accurately engages with the connecting rod 71. On the outside of the connecting rod 71, a mechanical lock is formed. At this time, the connecting rod 71 continues to move upward under the constraint of the slot 62. The displacement is converted into the rotational motion of the gripper 73 by the pull plate 72. The bottoms of multiple sets of grippers 73 synchronously retract towards the center to form a stable clamping force. This design ensures the precise movement trajectory of the gripper 73 through the positioning of the first guide groove 4, the second guide groove 10 and the slot 62. The linkage between the electronic push rod 52 and the lever-type limit plate 61 realizes the efficient conversion of power transmission. The distributed clamping of multiple sets of grippers 73 effectively disperses stress and avoids local deformation of the pipeline, which is suitable for the stable fixing of precision pipelines.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
