Description

Technical Field

[0001] The utility model provides a pipeline clamping device, which relates to the technical field of pipeline processing and production equipment. Background Art

[0002] During the current pipeline (steel pipe) laying process, the pipeline needs to be welded, threaded, etc. The existing pipeline clamping claws are divided into small-diameter types and large-diameter types. During construction, the clamping claws need to be replaced according to different pipeline selections.

[0003] Existing pipe clamps are divided into two types, such as Figure 1 The clamping block shown in the figure has a clamping surface set as an inclined surface, which is suitable for pipes with a diameter less than 3 inches. Clamping pipes with a diameter greater than 3 inches will cause deformation. For pipes with a diameter greater than 3 inches, the clamping block is as follows Figure 2 As shown, the clamping surface is set as an arc, which can ensure that the pipe will not deform during the clamping process. Therefore, in actual construction, it is often necessary to equip clamping devices for large and small diameter pipes at the same time, which is inconvenient and costly. Utility Model Content

[0005] To achieve the above purpose, the technical solution of the utility model is:

[0006] A pipe clamping device comprises two clamping blocks which can move towards or away from each other, each clamping block is provided with a clamping portion, each clamping portion has an inwardly concave clamping opening; the clamping opening has a symmetrical, intersecting upper clamping surface and a lower clamping surface, the upper clamping surface and the lower clamping surface both comprise mutually connected, inner-outer straight line portions and arcuate portions, the straight line portions of the upper clamping surface and the lower clamping surface intersect to form a V-shape.

[0007] The arc portion of the upper clamping surface and the arc portion of the lower clamping surface are arcs with the same radius.

[0008] The clamping block is provided with two or more clamping parts, and a gap is formed between adjacent clamping parts.

[0009] The width of the gap is greater than the width of the clamping portion.

[0010] The two clamping blocks are staggered and move toward each other, and the clamping portion of one clamping block can be embedded in the gap of the other clamping block.

[0011] The surface of the upper clamping surface and the surface of the lower clamping surface are both configured to be tooth-shaped.

[0014] The advantages of the utility model are: 1. The clamping surface of the clamp includes a straight portion and an arc portion, the straight portion is used to clamp a small pipe with a diameter less than 3 inches, and the arc portion is used to clamp a large pipe with a diameter greater than 3 inches, so that one clamping device can be suitable for pipes of various diameters; 2. Each clamping block is provided with a plurality of clamping portions, and a gap is reserved between the clamping portions. The two clamping blocks are staggered and can be embedded in each other, so that the clamping blocks do not need to be replaced, and the clamping device can be suitable for various pipeline construction sites; 3.

[0022] The utility model is further described below in conjunction with the accompanying drawings. The accompanying drawings are only used for exemplary description and cannot be understood as limiting the present patent.

[0023] In order to more concisely describe the present embodiment, some parts known to those skilled in the art but not related to the main content of the present invention are omitted in the drawings or descriptions. In addition, for the convenience of description, some parts in the drawings are omitted, enlarged or reduced, but they do not represent the size or entire structure of the actual product.

[0024] The utility model relates to a pipe clamping device, such as Figure 3As shown, it comprises two clamping blocks 1 that can move toward or away from each other, each clamping block 1 is provided with a clamping portion 2, and each clamping portion 2 has an inwardly concave clamping opening 3. In the prior art, the two clamping blocks 1 can move toward each other through a slide rail, or can be driven by a cylinder or a motor.

[0025] like Figure 4 , Figure 5 As shown, the clamp 3 is a V-shaped structure with an arc at the mouth end, and the clamp 3 has a symmetrical, intersecting upper clamping surface 31 and a lower clamping surface 32, and the upper clamping surface 31 and the lower clamping surface 32 both include a straight line portion 33 and an arc portion 34 connected to each other from the inside to the outside, and the straight line portion 33 of the upper clamping surface 31 and the straight line portion 33 of the lower clamping surface 32 intersect to form a V shape. When the two clamps 1 are closed, the straight line portion 33 is used to clamp a pipe with a diameter less than 3 inches.

[0026] like Figure 4 , Figure 5 As shown, the arc portion 34 of the upper clamping surface 31 and the arc portion 34 of the lower clamping surface 32 are symmetrical and are arcs with the same radius. When processing a pipe with a diameter greater than 3 inches, when the two clamps 1 are closed, the pipe is clamped at the arc portion 34, which will not cause the pipe to deform.

[0027] Preferably, if Figure 5 As shown, the clamping block 1 is provided with two or more clamping parts 2, and a gap 4 is formed between adjacent clamping parts.

[0028] Furthermore, the width of the gap 4 is greater than the width of the clamping portion 2 .

[0029] In order to allow a clamping device to clamp pipes of various diameters, the two clamping blocks 1 are staggered. When the two clamping blocks 1 move toward each other and close together, Figure 6 As shown, the clamping portion 2 of one clamping block 1 can be embedded in the gap 4 of the other clamping block, so that the two clamping blocks 1 can adapt to pipes of various calibers.

[0030] In order to increase the friction force of the clamping block 1 , the surface of the upper clamping surface 31 and the surface of the lower clamping surface 32 are both configured as tooth-like structures.

[0031] Alternatively, toothed anti-skid pads are provided on the surfaces of the upper clamping surface 31 and the lower clamping surface 32. Typically, the toothed anti-skid pads are rubber pads.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. That is, any equivalent changes and modifications made according to the content of the patent application scope of the present invention should be within the technical scope of the present invention.
