Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning devices, in particular to a chain-driven steel pipe cleaning device. Background Art

[0002] Steel pipe is a hollow long round steel material, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural parts. In addition, when the bending and torsional strengths are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. Steel pipes are usually manufactured by cold rolling and cold drawing. During cold drawing, one end of the steel pipe needs to be beaten into a small head to facilitate the insertion of the steel pipe into the mold for cold drawing. After cold drawing, the beaten end head is cut off. During production, steel pipes will produce unequal amounts of impurities and oxides on the outer wall. If they are not removed, the service life and quality of the steel pipe will be reduced. The steel pipe cleaning equipment in the prior art often places the steel pipe in a fixed device when cleaning it, and then sprays the cleaning liquid to clean the steel pipe. There is a disadvantage that the local cleaning of the steel pipe is not thorough, which will reduce the service life and quality of the steel pipe to a certain extent. Moreover, the steel pipe cleaning equipment in the prior art cannot dehydrate the residual water on the steel pipe after the steel pipe is cleaned, but needs to transport the steel pipe to the next process for dehydration and drying, which has complicated procedures and great limitations.

[0003] The existing patent CN116765057A discloses a chain-driven steel pipe cleaning device. By setting the three main rotating shafts with the middle one higher than the other two, the chain forms a triangular structure. The steel pipe can roll after passing the highest point of the chain, so that all parts of the steel pipe can be washed, the washing effect is good, and there are no dead corners. However, this device only places the steel pipe on a support frame. Under the impact of water pressure, the steel pipe is easy to fall or collide with the inner wall of the support frame, thereby causing scratches, affecting the efficiency of the steel pipe during use.

[0004] Therefore, we proposed a chain-driven steel pipe cleaning device to solve the above problems. Utility Model Content

[0005] The utility model aims at the problem that in the prior art, the steel pipe is only placed on the support frame. Under the impact of water pressure, the steel pipe is easy to fall or collide with the inner wall of the support frame, thereby causing scratches, which affects the efficiency of the steel pipe during use. The following technical solutions are proposed:

[0006] The chain-driven steel pipe cleaning device comprises a main roller, an auxiliary roller and a chain, wherein a plurality of connecting rods are installed at equal distances on the outer wall of the chain, and the top ends of the connecting rods are all installed at the middle of the bottom end of the support frame, and the inner wall of the support frame is installed with a side abutment plate for clamping the steel pipe through an adjustment mechanism;

[0007] The adjustment mechanism includes a first limiting groove opened at the bottom end of the inner wall of the support frame, and a first sliding rod is installed in the middle of the inner wall of the first limiting groove, and two groups of first sliding blocks are slidably connected to the outer wall of the first sliding bar, and the top end of the first sliding block is installed in the middle of the bottom end of the side abutment plate, and an extrusion spring is welded in the middle of the inner outer wall of the two groups of the first sliding blocks, and the middle part of the extrusion spring is surrounded on the outer wall of the first sliding bar.

[0008] The steel pipe to be cleaned is placed on the inner sides of the two groups of side abutment plates. Under the sliding action of the first sliding rod and the first sliding block and the elastic potential energy of the extrusion spring, the inner walls of the two groups of side abutment plates abut against the outer walls of the steel pipe, thereby ensuring the stability of the steel pipe placed on the inner side of the support frame. This effectively solves the problem that the steel pipe is prone to falling off or colliding with the inner wall of the support frame under the impact of water pressure in traditional cleaning devices, thereby causing scratches, affecting the efficiency of the steel pipe during use, thereby ensuring the practicability of the device during use.

[0009] As a preferred embodiment of the above technical solution, two groups of support rods are hingedly connected to the middle part of the outer wall of the side abutment plate, the outer top ends of the support rods are hingedly connected to the middle part of the inner outer wall of the second slider, the second sliders are symmetrically slidably connected to the outer wall of the second slide rod, the second slide rods are fixedly installed in the middle part of the inner wall of the second limiting groove, and the second limiting groove is symmetrically arranged in the middle part of the inner wall of the support frame.

[0010] Under the supporting effect of the supporting rod and the sliding effect of the second slider and the second sliding rod, the stability of the middle and upper parts of the two sets of side abutment plates is guaranteed during the opening or contraction process, which can further ensure the stable efficiency of steel pipe clamping.

[0011] As a preferred embodiment of the above technical solution, a plurality of groups of anti-slip rubber pads are glued to the inner wall of the side abutment plate at equal distances.

[0012] With the use of the anti-slip rubber pad, it is possible to prevent the inner wall of the side abutment plate from directly contacting the outer wall of the steel pipe and causing scratches, which would affect the use efficiency of the steel pipe. At the same time, the friction between the inner wall of the side abutment plate and the outer wall of the steel pipe can be increased to prevent slipping.

[0013] As a preferred embodiment of the above technical solution, the front view cross section of the side abutting plate is arc-shaped.

[0014] The arc shape can better fit the outer wall of the steel pipe, and the openings in the middle of the upper and lower end walls are small, which further ensures the practical efficiency of clamping the steel pipe.

[0015] The beneficial effects of the utility model are:

[0016] (1) The inner walls of the two sets of side abutment plates abut against the outer wall of the steel pipe, thereby ensuring the stability of the steel pipe placed inside the support frame. This effectively solves the problem that the steel pipe is prone to falling or colliding with the inner wall of the support frame under the impact of water pressure in traditional cleaning devices, thereby causing scratches, affecting the efficiency of the steel pipe during use, thereby ensuring the practicality of the device during use;

[0017] (2) Under the supporting effect of the supporting rod and the sliding effect of the second slider and the second slide rod, the stability of the middle and upper parts of the two sets of side abutment plates is guaranteed during the opening or contraction process, which can further ensure the stable efficiency of clamping the steel pipe.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

The specific matching and using method of the main roller 1, the auxiliary roller 2 and the chain 3 is consistent with that of patent CN116765057A. A plurality of groups of connecting rods 4 are installed at equal distances on the outer wall of the chain 3, and the top ends of the connecting rods 4 are all installed at the middle of the bottom end of the support frame 5. The inner wall of the support frame 5 is installed with a side abutment plate 10 for clamping a steel pipe through an adjustment mechanism;

[0026] The adjustment mechanism includes a first limiting groove 6 opened at the bottom end of the inner wall of the support frame 5, and a first sliding rod 7 is installed in the middle of the inner wall of the first limiting groove 6, and two groups of first sliding blocks 8 are slidably connected to the outer wall of the first sliding bar 7. The top end of the first sliding block 8 is installed in the middle of the bottom end of the side abutment plate 10, and an extrusion spring 9 is welded in the middle of the inner outer wall of the two groups of first sliding blocks 8, and the middle part of the extrusion spring 9 is surrounded on the outer wall of the first sliding bar 7.

[0027] The steel pipe to be cleaned is placed on the inner side of the two groups of side abutment plates 10. Under the sliding action of the first slide bar 7 and the first slider 8 and the elastic potential energy of the extrusion spring 9, the inner walls of the two groups of side abutment plates 10 abut against the outer wall of the steel pipe, thereby ensuring the stability of the steel pipe placed on the inner side of the support frame 5. This effectively solves the problem that the steel pipe is prone to falling off or colliding with the inner wall of the support frame under the impact of water pressure in traditional cleaning devices, thereby causing scratches, affecting the efficiency of the steel pipe during use, and ensuring the practicability of the device during use.

[0028] like Figure 2 and Figure 4 As shown, two groups of support rods 12 are hingedly connected to the middle of the outer wall of the side abutment plate 10, the outer top ends of the support rods 12 are hingedly connected to the middle of the inner outer wall of the second slider 13, the second sliders 13 are symmetrically slidably connected to the outer wall of the second slide rod 14, the second slide rods 14 are fixedly installed in the middle of the inner wall of the second limiting groove 15, and the second limiting groove 15 is symmetrically opened in the middle of the inner wall of the support frame 5.

[0029] Under the supporting effect of the supporting rod 12 and the sliding effect of the second slider 13 and the second slide rod 14, the stability of the middle and upper parts of the two sets of side abutment plates 10 is guaranteed during the opening or contraction process, which can further ensure the stable efficiency of steel pipe clamping.

[0030] like Figure 2 As shown, a plurality of groups of anti-slip rubber pads 11 are glued to the inner wall of the side abutment plate 10 at equal distances.

[0031] With the use of the anti-slip rubber pad 11, it is possible to prevent the inner wall of the side abutment plate 10 from directly contacting the outer wall of the steel pipe and causing scratches, which would affect the use efficiency of the steel pipe. At the same time, the friction between the inner wall of the side abutment plate 10 and the outer wall of the steel pipe can be increased to prevent slipping.

[0032] like Figure 2 As shown, the side abutment plate 10 has an arc-shaped front cross section.

[0033] The arc shape can better fit the outer wall of the steel pipe, and the openings in the middle of the upper and lower end walls are small, which further ensures the practical efficiency of clamping the steel pipe.

[0034] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
