Technical Field

[0001] The utility model relates to the field of pipeline clamping, in particular to a clamping device for pipeline production. Background Art

[0002] According to the search of Chinese patent CN220699551U, a multi-diameter clamping device for pipeline production has been developed, which belongs to the field of pipeline processing technology. It aims at the problem that it is inconvenient to clamp pipelines of different diameters in the prior art, which reduces the processing efficiency of pipelines. It includes a base, and a placement seat is arranged at the upper end of the base. A first threaded rod is rotatably connected to one side of the top of the placement seat. A moving rod is arranged on the outer thread sleeve of the first threaded rod, and a limiting block is fixed on one side of the moving rod. The utility model realizes the effect of the arc clamping plate on the pipeline by arranging structures such as the first threaded rod, the moving rod, the limiting block, the positioning rod 503 and the arc clamping plate, so as to maintain the stability of the pipeline during processing and improve the processing quality of the pipeline. The movable rod is conveniently limited by the arrangement of structures such as the movable rod, the slot, the second spring, the second telescopic rod and the limiting hole, so as to further improve the stability of the pipeline during clamping and facilitate the operation of the staff.

[0003] The patent utilizes structures such as the first threaded rod, the movable rod, the limit block, the positioning rod 503 and the arc-shaped clamping plate to achieve a stable clamping of the pipe, ensure the stability of the pipe during the processing, and thus improve the processing quality of the pipe. At the same time, the stability of the pipe clamping is enhanced by the combination of structures such as the movable rod, the slot, the second spring, the second telescopic rod and the limit hole. However, when the pipe is transported after production, pipes of different sizes will be clamped and transported. The device mainly focuses on clamping and fixing pipes of the same batch size.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1 - Figure 4 A clamping device for pipeline production shown in the figure includes a base 1 and a hydraulic rod 2. A bearing plate 3 is provided at the protruding end of the hydraulic rod 2. The height of the bearing plate 3 can be adjusted by extending or retracting the protruding end of the hydraulic rod 2, which not only facilitates the lifting and transportation of the clamped pipeline, but also provides additional convenience during the handling process. The bearing plate 3 is used to carry the pipeline that needs to be transported. The surface of the bearing plate 3 has multiple anti-slip pads 6 that are equidistantly arranged. These anti-slip pads 6 are made of elastic material and are not only elastic, but also can provide excellent anti-slip function, effectively increase the friction between the pipeline and the bearing plate 3, and ensure that the pipeline is stable during transportation.

[0022] A push rod is also provided on the surface of the base 1 for pushing the entire device, which is convenient for users to push the entire device. A sponge pad is installed on the push rod, which not only provides an anti-slip function, but also enhances the comfort when holding. In addition, a self-locking universal wheel is provided at the bottom of the base 1, so that the entire device can be moved easily and flexibly to meet the user's usage needs in different scenarios.

[0023] A clamping assembly 4 for clamping pipes of different sizes is provided on the carrier plate 3, and is mainly used to clamp pipes of different sizes of the same batch on the carrier plate 3;

[0024] The clamping assembly 4 includes a screw 401, a lifting plate 402, an electric push rod 403, a sleeve 404, a first clamp 405, a second clamp 406 and a sliding rod 407. The screw 401 is rotatably set on the surface of the supporting plate 3. The lifting plate 402 is threadedly connected to the screw 401 through a first threaded hole. The sliding rod 407 is set on the surface of the lifting plate 402. The lifting plate 402 is slidably connected to the outer wall of the sliding rod 407 through a sliding hole. Two electric push rods 403 are set on the surface of the lifting plate 402. The sleeve 404 is set at the protruding ends of the two electric push rods 403. The first clamp 405 is rotatably set on a sleeve 404 through the second threaded hole. The first clamp 405 is set in an eight-shaped structure. The eight-shaped structure can adapt to pipes of different diameters and shows strong compatibility. Its clamping force is evenly distributed, which effectively prevents the pipe from being deformed or damaged during the clamping process.

[0025] The second clamp 406 is rotatably set on another sleeve 404 through the third threaded hole. The second clamp 406 is set in a rectangular shape, which can provide a more stable clamping surface to ensure that the pipeline is not easy to shake or shift during the clamping process. The rectangular clamp can also better disperse the clamping force and reduce deformation or damage of the pipeline due to uneven force.

[0026] When it is necessary to clamp different pipes, the lifting plate 402 slides downward along the outer wall of the slide rod 407 by rotating the rotating disk 7 clockwise, and then the extended end of one of the electric push rods 403 is driven to extend to adjust the clamping force according to the shape of the placed pipe, and then the extended end of the other electric push rod 403 is driven to extend and adjust the clamping force according to the placed pipe;

[0027] When pipes have different shapes, we can respond flexibly by replacing different clamps and adjusting the angles between the clamps to meet the needs. The clamp design allows free rotation on the sleeve 404, so that it can be easily adjusted to the ideal clamping angle. When the clamp needs to be replaced, simply rotate the old clamp off the sleeve 404, and then install the appropriate new clamp to quickly complete the replacement.

[0028] The surface of the lifting plate 402 is provided with a positioning assembly 5 for clamping the pipe, which is mainly used for positioning the pipe on the bearing plate 3 before installation, and can also clamp an outer wall of the installed pipe;

[0029] The positioning assembly 5 includes a sliding groove 501, a slider 502, a positioning rod 503, a limiting groove 504, a fixing plate 505 and a limiting pin 506. The sliding groove 501 is opened on the surface of the lifting plate 402, the slider 502 is slidably set on the inner wall of the sliding groove 501, the positioning rod 503 is set on the surface of the slider 502, and the positioning rod 503 is slidably connected to the inner wall of the sliding groove 501, there are multiple limiting grooves 504 and they are equidistantly arranged on one side of the bearing plate 3, the fixing plate 505 is set on the side of the slider 502 close to the limiting groove 504, and the limiting pin 506 passes through the fixing plate 505 and is clamped with the limiting groove 504.

[0030] When pipes of different sizes are placed on the bearing plate 3 and need to be positioned, the distance between the positioning rods 503 is adjusted according to the sizes of the different pipes. First, the limiting pins 506 are pulled out of the limiting grooves 504 by hand, and then the spacing of the positioning rods 503 is slid according to the sizes of the pipes. The sliding of the positioning rods 503 drives the slider 502 to slide along the inner wall of the sliding groove 501, so as to separate pipes of different shapes to avoid mixing together. When the positioning rods 503 slide to a suitable position, the limiting pins 506 are inserted into the limiting grooves 504 for limiting, and then the pipes are placed on the bearing plate 3 between the positioning rods 503 that have just been adjusted.

[0031] When it is necessary to clamp the outer wall of the placed pipe, the limit pin 506 is pulled out of the limit groove 504, and the pipe is squeezed to move to one side of the supporting plate 3 by sliding the positioning rod 503. When the positioning rod 503 is close to the pipe, the limit pin 506 is inserted into the limit groove 504 for limiting, thereby clamping the outer side of the pipe.
