Description

Technical Field

[0001] This utility model relates to the field of equipment maintenance technology in the metallurgical industry, specifically a portable pipe clamp. Background Technology

[0002] Leaks frequently occur in pipelines supplying various media, including steam, water, compressed air, and nitrogen, during equipment maintenance in the metallurgical industry. The common tool for handling these leaks is the traditional clamp-type clamp. This type of clamp typically involves cutting a steel pipe to create two clamps, each with an arc of approximately 160° and an inner diameter equal to the outer diameter of the leaking pipe. Strip steel plates are welded to both sides of each pipe, and holes are drilled evenly on these plates to ensure concentricity during assembly. A rubber sheet is then cut to match the circumference and length of each clamp. Bolts matching the hole diameter are prepared, and the clamps are installed on the leaking pipe. The rubber sheet is then pressed onto the leak, and the clamps are tightened with bolts until the leak is eliminated. While this tool can eliminate leaks once tightened, it poses certain safety hazards during use. For example, when dealing with steam leaks, the high internal pressure of the pipeline can easily cause burns to maintenance personnel when the steam sprays out. When dealing with gas leaks, prolonged handling time can cause poisoning to maintenance personnel. Improper installation often leads to leaks and rework, posing certain safety risks. Utility Model Content

The adjusting handle is located inside the adjusting sleeve and is movably connected to the adjusting sleeve. The adjusting sleeve is hinged to the clamping arms through a connecting plate. The lower ends of the two clamping arms are connected to the clamping plate.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This utility model has a simple structure and is easy to carry.

[0029] The present invention will be further described below with reference to specific embodiments. The purpose of this description is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention. Example 1:

[0030] like Figure 1 return Figure 8 As shown, a portable pipe clamp consists of a clamping plate 7, an adjusting handle 1, and clamping arms 4 placed on both sides of the adjusting handle 1. An adjusting sleeve 2 is provided between the two clamping arms 4, and the adjusting sleeve 2 is movably connected to the adjusting handle 1. Fixing rods 3 are fixedly connected to both sides of the lower part of the adjusting sleeve 2, and the fixing rods 3 are symmetrically arranged on both sides of the adjusting sleeve 2. The upper ends of the two clamping arms 4 are respectively hinged to the fixing rods 3 on their respective sides. A connecting plate 5 is hinged between the lower end of the adjusting handle 1 and the clamping arms 4.

[0031] In this embodiment, each fixing rod 3 is inclined downward at an angle of 30°.

[0032] The lower end of the adjusting handle 1 passes through the adjusting sleeve 2 and extends to the bottom of the adjusting sleeve 2, and the adjusting handle 1 slides up and down along the adjusting sleeve 2; the adjusting handle 1 has a threaded structure on the outside, and the lower end of the adjusting handle 1 is threadedly connected to the connecting sleeve 13. The connecting sleeve 13 has ear plates 9 symmetrically welded on both sides. The ear plates 9 are hinged to the upper end of the connecting plate 5 on the same side, and the lower end of the connecting plate 5 is hinged to the lower part of the support arm on the same side; the two connecting plates 5 are connected by a spring 6.

[0033] In this embodiment, in order to facilitate pushing the adjustment handle 1, a handle 8 perpendicular to the adjustment handle 1 is welded to the top of the adjustment handle 1.

[0034] The lower ends of the two clamping arms 4 are respectively provided with arc-shaped clamping plates 7. The two clamping plates 7 are cut from steel pipes. Two steel plates are welded to the back of each clamping plate 7 as connecting seats 10. The connecting seats 10 on the back of each clamping plate 7 are detachably connected to the corresponding clamping arm 4 by bolt assembly.

[0035] A rubber sheet 11 is attached to the inner surface of the clamp 7.

[0036] In this embodiment, the two clamping plates 7 are fastened together under the tension of the spring 6 before use. When a leak 12 appears in the pipeline, the location of the leak 12 is first confirmed, and then the rust and dirt around the leak 12 on the pipeline are cleaned to ensure that there are no weld spatters or other residues. Then, the operator holds the adjusting sleeve 2 with one hand and pushes the handle 8 with the other hand, so that the adjusting handle 1 slides down along the sleeve. At the same time as the adjusting handle 1 slides down, the two support arms open and are placed on both sides of the steel pipe. The position of the clamping plate 7 is adjusted so that the center of the clamping plate 7 is aligned with the location of the leak 12. The adjusting handle 1 is released, and the two clamping arms 4 close under the tension of the spring 6, so that the clamping plate 7 clamps the pipeline.

[0037] In this embodiment, a spring 6 is added so that the connecting plate 5 is subjected to the elastic force of the spring 6, causing the two clamping plates 7 to clamp the pipe. This can quickly eliminate the leak point 12 in the pipe and also prevent the operator from approaching the leak point 12, ensuring the safety of the maintenance process. Example 2:

[0038] The difference between this embodiment and Embodiment 1 is that:

[0039] like Figures 5 to 11 As shown, the inner wall of the adjusting sleeve 2 is provided with an internal thread structure, and the adjusting handle 1 has an external thread structure. The lower end of the adjusting handle 1 passes through the adjusting sleeve 2, and the adjusting handle 1 is threadedly connected to the adjusting sleeve 2.

[0040] The adjusting handle 1 is threaded with two nuts 14 at the lower end of the adjusting sleeve 2. An annular connecting sleeve 13 is provided between the two nuts 14 and is fitted onto the adjusting handle 1. The position of the connecting sleeve 13 can be adjusted by turning the two nuts 14.

[0041] In this embodiment, when used to seal the pipe leak 12, the operator holds the adjusting sleeve 2 with one hand and rotates the adjusting handle 1 with the other hand, so that the adjusting handle 1 moves downward along the adjusting sleeve 2, while the two clamping arms 4 open. The two clamping arms 4 are placed on both sides of the steel pipe, and the position of the clamping plate 7 is adjusted so that the center of the clamping plate 7 is aligned with the position of the leak 12. Then the adjusting handle 1 is rotated in the opposite direction until the two clamping plates 7 clamp the pipe tightly, and the leak 12 is eliminated.

[0042] In this embodiment, the adjusting handle and the adjusting sleeve are connected by threads, which allows for manual adjustment of the clamping tightness of the clamp on the pipe, thereby improving the stability of the clamp holding the pipe.

[0043] The above description is merely a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
