Description

Technical Field

[0001] This utility model relates to the technical field of galvanized steel pipe production equipment, specifically to a clamp for galvanized steel pipe production. Background Technology

[0002] Galvanized steel pipes are divided into cold-dip galvanized steel pipes and hot-dip galvanized steel pipes. Galvanized steel pipes are welded steel pipes with a hot-dip or electro-galvanized layer on the surface. Galvanizing increases the corrosion resistance of steel pipes and extends their service life. Galvanized pipes have a wide range of applications. In addition to being used as pipelines for transporting general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially in offshore oil fields; pipes for oil heaters, condensers, and coal tar washing oil exchangers in chemical and coking equipment; and pipes for trestle piles and support frames in mine tunnels.

[0003] During the production and processing of galvanized steel pipes, the pipes need to be fixed and clamped to ensure their stability during processing. However, ordinary clamps can easily leave clamp marks on the surface of the galvanized steel pipes, damaging them. They also have problems such as uneven clamping force and complicated operation, which affect production efficiency and product quality. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a fixture for the production of galvanized steel pipes, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model proposes a clamp for galvanized steel pipe production, including: a base, a support plate, and a pneumatic clamp. The support plate is movably disposed above the base. The pneumatic clamp is connected to the end face of the support plate. Two support plates and two pneumatic clamps are provided, symmetrically distributed. Each pneumatic clamp includes an airbag clamp and a rubber pad. The end face of the airbag clamp is connected to the support plate. The rubber pad is disposed on the opposite end faces of the two airbag clamps, and the opposite end faces of the two airbag clamps are arc-shaped. The shape of the rubber pad matches the arc-shaped end face of the airbag clamp, and the base is provided with several locking holes. The above-mentioned clamp for producing galvanized steel pipes, through the combined use of the airbag clamp and the rubber pad, can prevent the clamp from leaving clamp marks on the surface of the galvanized steel pipe, thus preventing damage to the steel pipe. The arc-shaped design of the airbag clamp and the rubber pad increases the contact area between the clamp and the galvanized steel pipe, improving the clamping force and the uniformity of the clamping force distribution, thereby improving product quality. The locking holes allow the clamp to be fixed when needed.

[0006] Furthermore, the airbag clamp has an inflation port on its side, and the inflation port is equipped with a cover. The cover is connected to the side of the airbag clamp via a connecting rope. The inflation port allows gas to be added to the airbag clamp, preventing the clamping force from being reduced due to insufficient gas inside the airbag clamp.

[0007] Furthermore, the support plate is connected to the base via a sliding device; the sliding device allows the support plate to move the pneumatic clamp, thus the clamp can be applied to galvanized steel pipes of different diameters, improving the applicability of the clamp.

[0008] Furthermore, the sliding device includes a sliding groove, a sliding block, and a sliding column. The sliding groove is located on the upper surface of the base, and its length extends along the length direction of the base. The sliding groove provides space for the sliding block to be placed.

[0009] Furthermore, the slider is located within the groove, and the shape and size of the slider match the groove; by setting the slider and its shape and size, the stability of the slider during sliding is improved.

[0010] Furthermore, the lower end of the sliding column is connected to the slider, and the upper end of the sliding column is connected to the support plate; the sliding column serves to connect the support plate and the slider.

[0011] Furthermore, the surface of the slide column is provided with threads extending along the height direction of the slide column, and a nut is fitted onto the slide column; through the cooperation of the nut and the threads, the pneumatic clamp can be locked to prevent the galvanized steel pipe from falling off.

[0012] Furthermore, the cross-section of the slide groove is convex, and there is a distance between the two ends of the slide groove and the two end faces of the base to prevent the slide column from slipping off; the design of the slide groove cross-section further improves the stability of the slider when it moves.

[0013] Furthermore, it also includes a placement device, which is located above the base and below the pneumatic clamp. The placement device includes two placement plates and a telescopic plate. With the placement device, when clamping the galvanized steel pipe, the galvanized steel pipe can be placed on the placement device first, so as to avoid too much height difference between the two ends of the galvanized steel pipe, which would increase the difficulty of clamping the galvanized steel pipe. In addition, the setting of the placement device allows the clamp to be used as a placement rack.

[0014] Furthermore, the two placement plates are respectively connected to the lower ends of the two support plates, and each of the opposite end faces of the two placement plates is provided with a moving groove, with both ends of the telescopic plate located in the moving groove; through the cooperation of the moving groove and the telescopic plate, the placement device is prevented from obstructing the movement of the pneumatic clamp.

[0015] As described above, the clamp for producing galvanized steel pipes provided by this utility model has the following beneficial effects: the combined use of the airbag clamp and the rubber pad can prevent the clamp from leaving clamp marks on the surface of the galvanized steel pipe, thus preventing damage to the steel pipe. The arc shape of the airbag clamp and the rubber pad increases the contact area between the clamp and the galvanized steel pipe, which can improve the clamping force and the uniformity of the clamping force distribution, thereby improving the quality of the product. This clamp also has the advantages of simple structure and convenient operation, which improves production efficiency. Attached Figure Description

[0017] Figure 2 This is a cross-sectional three-dimensional structural diagram of the present invention. Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-2 As shown, this utility model provides a clamp for producing galvanized steel pipes: it includes a base 1, a support plate 2, and a pneumatic clamp 3. The support plate 2 is movably disposed above the base 1. The pneumatic clamp 3 is connected to the end face of the support plate 2. There are two of each of the support plate 2 and the pneumatic clamp 3, which are symmetrically distributed. Each pneumatic clamp 3 includes an airbag clamp 31 and a rubber pad 32. The end face of the airbag clamp 31 is connected to the support plate 2. The rubber pad 32 is disposed on the opposite end faces of the two airbag clamps 31. The opposite end faces of the two airbag clamps 31 are arc-shaped. The shape of the rubber pad 32 matches the arc-shaped end face of the airbag clamp 31. The base 1 is provided with several locking holes 11, which can be used to fix the clamp when needed. The use of the airbag clamp 31 and the rubber pad 32 together can prevent the clamp from leaving clamp marks on the surface of the galvanized steel pipe and prevent damage to the steel pipe. The arc shape of the airbag clamp 31 and the rubber pad 32 increases the contact area between the clamp and the galvanized steel pipe, which can improve the clamping force and the uniformity of the clamping force distribution, thereby improving the quality of the product.

[0020] The airbag clamp 31 has an inflation port 33 on its side, and the inflation port 33 is equipped with a cover 34. The cover 34 is connected to the side of the airbag clamp 31 by a connecting rope 35. The inflation port 33 allows the airbag clamp 31 to be filled with gas, preventing the clamping force of the airbag clamp 31 from being reduced due to insufficient gas. The connecting rope 35 also prevents the cover 34 from being lost.

[0021] The support plate 2 is connected to the base 1 via a sliding device 4. The sliding device 4 allows the support plate 2 to move the pneumatic clamp 3, thus the clamp can be used for galvanized steel pipes of different diameters, improving the applicability of the clamp.

[0022] The sliding device 4 includes a sliding groove 41, a slider 42 and a sliding column 43. The sliding groove 41 is located on the upper end surface of the base 1 and extends along the length of the base 1. The sliding groove 41 provides space for the slider 42 to be placed.

[0023] The slider 42 is located inside the groove 41, and the shape and size of the slider 42 match the groove 41. The slider 42 and its shape and size are set to improve the stability of the slider 42 when sliding.

[0024] The lower end of the sliding column 43 is connected to the slider 42, and the upper end of the sliding column 43 is connected to the support plate 2. The sliding column 43 serves to connect the support plate 2 and the slider 42.

[0025] The slide column 43 has a thread 44 extending along its height direction on its surface. The slide column 43 is fitted with a nut 45. The pneumatic clamp 3 can be locked by the cooperation of the nut 45 and the thread 44 to prevent the galvanized steel pipe from falling off.

[0026] The slide groove 41 has a "convex" shaped cross section, and there is a distance between the two ends of the slide groove 41 and the two end faces of the base 1 to prevent the slide column 43 from slipping. The cross section of the slide groove 41 further improves the stability of the slider 42 when it moves.

[0027] The system also includes a placement device 5, which is located above the base 1 and below the pneumatic clamp 3. The placement device 5 includes two placement plates 51 and a telescopic plate 52. By using the placement device 5, the galvanized steel pipe can be placed on the placement device 5 before clamping, thus avoiding excessive height difference between the two ends of the galvanized steel pipe, which would increase the difficulty of clamping the galvanized steel pipe. In addition, the placement device 5 allows the clamp to also be used as a placement rack.

[0028] The two placement plates 51 are respectively connected to the lower ends of the two support plates 2. The opposite end faces of the two placement plates 51 are provided with moving grooves 53. The two ends of the telescopic plate 52 are located in the moving grooves 53. Through the cooperation of the moving grooves 53 and the telescopic plate 52, the placement device 5 is prevented from obstructing the movement of the pneumatic clamp 3.

[0029] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto.
