TECHNICAL FIELD
[0001] The present application relates to the technical field of pipe installation tools, and more particularly to a pipe aligning clamp and a device thereof. BACKGROUND
[0002] In the installation process of steam pipes or water pipes, the pipes need to be connected, and currently two pipes are mainly connected into one by welding. The existing pipe lacks a special clamp during alignment, resulting in low alignment installation efficiency and prolonging the pipe installation period. CONTENT OF THE UTILITY MODEL
[0003] Therefore, the present application provides a pipe aligning clamp and a device thereof, aiming to improve the low alignment installation efficiency of the existing pipe.
[0004] In a first aspect, the present application provides a pipe aligning clamp, comprising two aligning units oppositely arranged and fixedly connected along a first direction, each aligning unit corresponding to a pipe.
[0005] Each aligning unit comprises an L-shaped clamping piece and an I-shaped clamping piece. The L-shaped clamping piece comprises two horizontal parts and a vertical part. The two horizontal parts are oppositely arranged along a third direction, and the two horizontal parts are fixedly connected to the two ends of the vertical part, respectively. The I-shaped clamping piece is opposite to the vertical part along a second direction. The two ends of the I-shaped clamping piece are correspondingly and detachably fixedly connected to the ends of the two horizontal parts away from the vertical part. The horizontal part, the vertical part and the I-shaped clamping piece are all provided with a plurality of position adjusting threaded holes, and a position adjusting bolt is arranged in each position adjusting threaded hole. The pipe is arranged in the space between the L-shaped clamping piece and the I-shaped clamping piece, and one end of the position adjusting bolt is used to abut against the outer surface of the pipe. The first direction, the second direction and the third direction are perpendicular to each other.
[0006] Preferably, the two L-shaped clamping pieces and / or the two I-shaped clamping pieces in the two aligning units are fixedly connected by connecting rods.
[0007] Preferably, the ends of the I-shaped clamping piece are connected to the ends of the corresponding horizontal parts away from the vertical part by connecting bolts.
[0008] Preferably, the L-shaped clamping piece is an integral part.
[0009] Preferably, the number of position adjusting threaded holes is a plurality, and the plurality of position adjusting threaded holes are uniformly distributed on the horizontal part, the vertical part and the I-shaped clamping piece.
[0010] In a second aspect, the present application provides a pipe aligning device, comprising an aligning mechanism and the pipe aligning clamp provided in the first aspect of the present application, wherein the aligning mechanism is used to make the center lines of the two pipes corresponding to the two aligning units collinear.
[0011] Compared with the prior art, the pipe aligning clamp and the device thereof provided in the present application at least achieve the following beneficial effects:
[0012] In the present application, the pipe aligning clamp comprises two aligning units, each of which is used to clamp one corresponding pipe, i.e., the corresponding pipe is arranged in the space between the U-shaped clamping piece and the I-shaped clamping piece of the corresponding aligning unit. In use, the pipe is operated to make the end faces (i.e., on the plane determined by the second direction and the third direction) of the two pipes substantially aligned, and the positioning bolt is rotated to make the end of the positioning bolt abut against the outer surface of the pipe, so that the pipe can be positioned and clamped. Specifically, because the longitudinal part of the U-shaped clamping piece and the I-shaped clamping piece are opposite along the second direction, the ends of the positioning bolts arranged in the positioning threaded holes on the longitudinal part and the I-shaped clamping piece respectively abut against both sides of the pipe along the second direction, so as to ensure the position of the pipe fixed in the second direction; because the two transverse plates of the U-shaped clamping piece are opposite along the third direction, the ends of the positioning bolts arranged in the positioning threaded holes on the two transverse plates respectively abut against both sides of the corresponding pipe along the third direction, so as to ensure the position of the pipe fixed in the third direction; in addition, the ends of the positioning bolts in the above four directions all have friction with the outer surface of the pipe, so that when the outer surface of the pipe is circular in cross section, the friction can limit the rotation of the pipe; when the outer surface of the pipe is rectangular in cross section, the plurality of positioning bolts can limit the rotation of the pipe, so as to ensure that the pipe does not rotate. In this way, the two aligning units can respectively position and clamp the two pipes, the clamping is reliable, the pipes are not easy to shake, and the two pipes are clamped and fixed by the clamp, the clamping process is simple and efficient; because the two ends of the I-shaped clamping piece are respectively and detachably fixedly connected with the ends of the two transverse parts away from the longitudinal part, when the two pipes are welded, the ends of the I-shaped clamping piece and the ends of the transverse parts away from the longitudinal part are detached, so that the two pipes welded into one can be taken out of the clamp.
[0013] In the specific operation of the present application, the center line of the pipeline can be moved along the cross section (the plane determined by the second direction and the third direction) direction of the pipeline by rotating the positioning bolt, so that the center line of the two pipes clamped by the two alignment units can be moved as close as possible and in the direction of alignment, which facilitates the subsequent alignment of the center lines of the two pipes by using other alignment tools and saves the alignment time; during the alignment process of the center lines of the two pipes, the center line position of the pipeline needs to be adjusted, the positioning bolt can be continuously fine-tuned and rotated, and the pipeline can move on the plane determined by the second direction and the third direction. The adjustment process is convenient and efficient. After the center lines of the two pipelines are adjusted to be collinear, the end portions of the two pipelines are welded.
[0014] In addition, in the present application, the end portion of the positioning bolt can be moved by rotating the positioning bolt, so that the distance between the end portion of the positioning bolt inserted in the positioning thread hole on the longitudinal portion and the end portion of the positioning bolt inserted in the positioning thread hole on the I-shaped clamping piece can be adjusted, and the distance between the end portions of the positioning bolts inserted in the positioning thread holes on the two transverse plates can also be adjusted. Therefore, the pipeline alignment clamp provided by the present embodiment can be suitable for clamping pipelines of various sizes, and has a wide range of applications.
[0015] Of course, any product implementing the present application does not necessarily need to achieve all the technical effects described above at the same time.

[0027] Figure 1 A perspective structural schematic view of a pipe aligning clamp provided by an embodiment of the present application is shown.
[0028] Reference should be made to Figure 1 The present application provides a pipe aligning clamp, which comprises two aligning units 100 oppositely arranged and fixedly connected along a first direction D1, each aligning unit 100 corresponding to one pipe; each aligning unit 100 comprises an L-shaped clamping piece 110 and an I-shaped clamping piece 120, the L-shaped clamping piece 110 comprises two horizontal parts 111 and one vertical part 112, the two horizontal parts 111 are oppositely arranged along a third direction D3, and the two horizontal parts 111 are fixedly connected to two ends of the vertical part 112 respectively, the I-shaped clamping piece 120 is opposite to the vertical part 112 along a second direction D2, and two ends of the I-shaped clamping piece 120 are correspondingly and detachably fixedly connected to the ends of the two horizontal parts 111 away from the vertical part 112, the horizontal part 111, the vertical part 112 and the I-shaped clamping piece 120 are all provided with a plurality of position adjusting threaded holes 101, and a position adjusting threaded bolt 102 is arranged in each position adjusting threaded hole 101; the pipe is arranged in the space between the L-shaped clamping piece 110 and the I-shaped clamping piece 120, and one end of the position adjusting threaded bolt 102 is used to abut against the outer surface of the pipe, the first direction D1, the second direction D2 and the third direction D3 are perpendicular to each other.
[0029] In the embodiment, the pipe aligning clamp comprises two aligning units 100, each of which is used to clamp a corresponding pipe, i.e. the corresponding pipe is arranged in the space between the U-shaped clamping piece 110 and the I-shaped clamping piece 120 of the corresponding aligning unit 100. In use, the pipes are operated to make the end faces (i.e. the planes determined by the second direction D2 and the third direction D3) of the two pipes substantially aligned, the positioning bolt 102 is rotated to make the end of the positioning bolt 102 abut against the outer surface of the pipe, so that the pipe can be positioned and clamped. Specifically, because the longitudinal part 112 of the U-shaped clamping piece 110 and the I-shaped clamping piece 120 are opposite along the second direction D2, the end of the positioning bolt 102 arranged in the positioning threaded hole 101 on the longitudinal part 112 and the end of the positioning bolt 102 arranged in the positioning threaded hole 101 on the I-shaped clamping piece 120 abut against the two sides of the pipe along the second direction D2 respectively, so as to ensure the position of the pipe fixed along the second direction D2; because the two transverse plates 111 of the U-shaped clamping piece 110 are opposite along the third direction D3, the ends of the positioning bolts 102 arranged in the positioning threaded holes 101 on the two transverse plates 111 abut against the two sides of the corresponding pipe along the third direction D3 respectively, so as to ensure the position of the pipe fixed along the third direction D3; in addition, the ends of the positioning bolts 102 in the above four directions all have friction with the outer surface of the pipe, so that when the outer surface of the pipe is circular in cross section, the friction can limit the rotation of the pipe; when the outer surface of the pipe is rectangular in cross section, the plurality of positioning bolts 102 can already limit the rotation of the pipe, so as to ensure that the pipe does not rotate. In this way, the two pipes can be positioned and clamped by the two aligning units 100 respectively, the clamping is reliable, the pipes are not easy to shake, and the two pipes can be clamped and fixed by the clamp, the clamping process is simple and efficient; because the two ends of the I-shaped clamping piece 120 are respectively and detachably fixedly connected with the ends of the two transverse plates 111 away from the longitudinal part 112, when the two pipes are welded to be aligned, the ends of the I-shaped clamping piece 120 and the ends of the transverse plates 111 away from the longitudinal part 112 are detached, so that the two pipes welded to be integrated can be taken out from the clamp.
[0030] In the specific operation of the embodiment, the center line of the pipeline can be moved along the cross section (the plane determined by the second direction D2 and the third direction D3) of the pipeline by rotating the positioning bolt 102, so that the center lines of the two pipelines clamped by the two alignment units 100 can be moved as close as possible and in the direction of alignment, which facilitates the subsequent alignment of the center lines of the two pipelines by using other alignment tools and saves the alignment time; during the alignment of the center lines of the two pipelines, the center line position of the pipeline needs to be adjusted, the positioning bolt 102 can be continuously fine-tuned and rotated, and the pipeline can be moved on the plane determined by the second direction D2 and the third direction D3, and the adjustment process is convenient and efficient. After the center lines of the two pipelines are adjusted to be collinear, the end portions of the two pipelines are welded.
[0031] In addition, in the embodiment, the end portion of the positioning bolt 102 can be moved by rotating the positioning bolt 102, so that the distance between the end portion of the positioning bolt 102 passing through the positioning threaded hole 101 on the longitudinal portion 112 and the end portion of the positioning bolt 102 passing through the positioning threaded hole 101 on the I-shaped clamping piece 120 can be adjusted, and the distance between the end portions of the positioning bolts 102 passing through the positioning threaded holes 101 on the two transverse plates 111 can also be adjusted. Thus, the pipeline alignment clamp provided by the embodiment can be suitable for clamping pipelines of various sizes, and has a wide range of applications.
[0032] Referring to Figure 1 In some embodiments, the two H-shaped clamping pieces 110 and / or the two I-shaped clamping pieces 120 in the two alignment units 100 are fixedly connected by the connecting rod 200. In this way, the fixed connection between the two alignment units 100 is achieved, and the fixed connection mode is simple in structure and reliable in connection.
[0033] In one specific embodiment, the two H-shaped clamping pieces 110 in the two alignment units 100 are fixedly connected by the connecting rod 200. In another specific embodiment, the two I-shaped clamping pieces 120 in the two alignment units 100 are fixedly connected by the connecting rod 200. In another specific embodiment, the two H-shaped clamping pieces 110 and the two I-shaped clamping pieces 120 in the two alignment units 100 are fixedly connected by the connecting rod 200.

[0034] Referring to Figure 1In some embodiments, the end of the I-shaped clamping piece 120 and the end of the corresponding horizontal part 111 away from the longitudinal part 112 are connected by a connecting bolt 130. In this way, the end of the I-shaped clamping piece 120 and the end of the corresponding horizontal part 111 away from the longitudinal part 112 can be detachably fixed and connected, and the detachable fixed connection has a simple structure and is easy to manufacture and obtain.
[0035] Referring to Figure 1 In some embodiments, the H-shaped clamping piece 110 is an integral molding. In this way, the H-shaped clamping piece 110 has a simple structure and is easy to manufacture.
[0036] Referring to Figure 1 The number of the positioning threaded holes 101 is multiple, and the multiple positioning threaded holes 101 are uniformly distributed on the horizontal part 111, the longitudinal part 112 and the I-shaped clamping piece 120. In this way, the position of the positioning bolt 102 can be adjusted according to the shape of the outer surface of the pipe, and the positioning bolt 102 is adjusted to be connected with different positioning threaded holes 101, so that the clamp can adapt to the pipe with different shapes of the outer surface, and the range of the pipe that the clamp can be applied to is expanded; the positioning bolt 102 can also be arranged in the multiple positioning threaded holes 101 on the horizontal part 111, the longitudinal part 112 and the I-shaped clamping piece 120, so as to increase the contact area between the end of the positioning bolt 102 and the outer surface of the pipe, and improve the clamping stability and reliability of the pipe.
