Description

Technical Field

[0001] The utility model relates to the field of steel pipe packaging, in particular to a supporting device for fixed steel pipes. Background Art

[0002] A steel pipe is a hollow long steel bar with various uses, and its main uses include transporting fluids such as petroleum, natural gas, water, gas, steam, etc.

[0003] After the production of steel pipes, they usually need to be packaged to prevent damage and pollution during transportation. Traditional packaging methods include using woven bags, films or other materials to wrap the steel pipes. Usually, the steel pipes are placed on a material rack so that the openings of the woven bags or other packaging materials can be better aligned with the steel pipes to achieve wrapping.

[0004] However, this part in contact with the material rack is difficult to be effectively covered by the packaging material. Specifically, it is difficult for the packaging material to directly cross over from the position where the material rack contacts the steel pipe to cover this position of the steel pipe. And especially for products such as seamless steel pipes with a relatively large weight (the single-piece weight can reach more than 1 ton), it is difficult for manual operation to lift them for packaging, and using other auxiliary equipment will also bring inconvenience. Therefore, this part of the steel pipe at the support position cannot be conveniently wrapped by the packaging material and often cannot be effectively protected, resulting in this part of the steel pipe being scratched or polluted during the packaging process, thus affecting the quality of the product. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a supporting device for fixed steel pipes that applies force to the linkage rod to drive the lifting rod on the hydraulic pump to move up and down, so that this part of the steel pipe at the position in contact with the material rack can be lifted, thus providing convenience for packaging.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: including a material rack and several steel pipes, the axial directions of the steel pipes extend along the left and right, each steel pipe is located above the material rack, and it also includes a hydraulic pump, a hydraulic cylinder, a linkage rod and a mounting seat. The hydraulic pump is linked with the hydraulic cylinder. The hydraulic pump includes a lifting rod that slides up and down. The hydraulic cylinder includes a mating rod that slides up and down. The lifting rod is detachably connected to the material rack. The linkage rod is rotatably installed on the mounting seat and a mating seat is arranged on the linkage rod. The mating seat is connected to the lifting rod.

[0007] The utility model is further set as: the top of the lifting rod is circumferentially provided with an external thread, and the material rack is provided with a threaded hole corresponding to the lifting rod.

[0008] The present utility model is further configured as follows: The material rack includes a front baffle, a rear baffle, and a connecting plate located between the front baffle and the rear baffle. The included angles between the front baffle and the connecting plate and between the rear baffle and the connecting plate are both 120°. Moreover, the front baffle is inclined from front to back from top to bottom, and the rear baffle is inclined from back to front from top to bottom.

[0009] The present utility model is further configured as follows: The linkage rod includes a connecting section rotatably connected to the mounting seat and a contact section. The mating seat is located on the connecting section, and the contact section is inserted into the connecting section and detachably connected to the connecting section.

[0010] The present utility model is further configured as follows: An installation ring made of a material prone to deformation is provided on the front side of the connecting section. A plurality of installation inserts are circumferentially provided on the contact section, and installation slots are provided on the installation ring corresponding to the installation inserts.

[0011] The present utility model is further configured as follows: It further includes a support seat and a limiting platform. The hydraulic pump and the hydraulic cylinder are both located on the support seat. The number of the limiting platforms is two, and they are respectively located on the left and right sides of the support seat. Limiting blocks protrude upward on the front and rear sides of each limiting platform.

[0012] The present utility model is further configured as follows: The material rack is made of hard nylon material.

[0013] By adopting the above technical solution, driving the linkage rod to rotate downward causes the mating rod to move downward. According to Pascal's principle (Pascal's principle is prior art and will not be specifically described here), the downward movement of the mating rod drives the lifting rod to move upward. Similarly, driving the linkage rod to rotate upward causes the mating rod to move upward, and the upward movement of the mating rod drives the lifting rod to move downward. Therefore, by applying force to the linkage rod, the height adjustment of the lifting rod can be achieved. Thus, when during the packaging process of the steel pipe, the packaging material abuts against the end face of the material rack and cannot continue to wrap the steel pipe to the left, at this time, by adjusting the height of the lifting rod, the material rack can be moved downward so that the packaging material can cover this part of the steel pipe located on the material rack. Then, the force applied to the linkage rod is released. At this time, the material rack moves upward so that the steel pipe can be stably located on the material rack. During use, by stepping on the linkage rod, while the operator uses the equipment for temporary support, packaging can also be carried out, enabling one-person operation without increasing the workload.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] As Figures 1 - 6 shown, the present utility model discloses a support device for a fixed steel pipe 2, including a material rack 1 and a plurality of steel pipes 2. The axial direction of each steel pipe 2 extends left and right, and each steel pipe 2 is located above the material rack 1. It also includes a hydraulic pump 3, a hydraulic cylinder 4, a linkage rod 5 and a mounting seat 6. The hydraulic pump 3 is linked with the hydraulic cylinder 4. The hydraulic pump 3 includes a lifting rod 31 that slides up and down. The hydraulic cylinder 4 includes a mating rod 41 that slides up and down. The lifting rod 31 is detachably connected to the material rack 1 by means of threads, buckles, etc. The linkage rod 5 is rotatably installed on the mounting seat 6 and a mating seat 53 is arranged on the linkage rod 5. The mating seat 53 is connected to the lifting rod 31. By driving the linkage rod 5 to rotate downward, the mating rod 41 is made to move downward. According to Pascal's principle, P = F / A. Therefore, when the mating rod 41 is pushed, a smaller force is applied to the rod with a smaller radius at the bottom. The mating rod 41 can push the hydraulic oil from the hydraulic cylinder 4 into the cavity of the hydraulic pump 3 where the lifting rod 31 with a larger radius is located at the bottom. At this time, the lifting rod 31 is pushed upward and moves upward (Pascal's principle is prior art and will not be specifically described here). Similarly, by driving the linkage rod 5 to rotate upward, the mating rod 41 is made to move upward, and the upward movement of the mating rod 41 will drive the lifting rod 31 to move downward. Therefore, by applying force to the linkage rod 5, the height adjustment of the lifting rod 31 can be achieved. Therefore, when in the process of packaging the steel pipe 2, when the packaging material abuts against the end face of the material rack 1 and cannot continue to wrap the steel pipe 2 to the left, at this time, by adjusting the height of the lifting rod 31, the material rack 1 can be moved downward so that the packaging material can cover this part of the steel pipe 2 located on the material rack 1. Then, the force applied to the linkage rod 5 is released. At this time, the material rack 1 moves upward so that the steel pipe 2 can be stably located on the material rack 1. And during use, by stepping on the linkage rod 5, while the operator uses the equipment for temporary support, packaging can also be carried out, realizing one-person operation without increasing the workload.

[0031] Preferably, an external thread 311 is circumferentially arranged at the top of the lifting rod 31, and the material rack 1 is provided with a threaded hole 11 corresponding to the lifting rod 31. Since by rotating the material rack 1, the lifting rod 31 can be separated from the material rack 1, and different material racks 1 can be replaced to cooperate with the packaging of different product shapes, which provides convenience for the packaging of the steel pipe 2.

[0032] Among them, the material rack 1 includes a front baffle 12, a rear baffle 13 and a connecting plate 14 located between the front baffle 12 and the rear baffle 13. The angle between the front baffle 12 and the connecting plate 14 and the angle between the rear baffle 13 and the connecting plate 14 are both 120°, and the front baffle 12 is inclined from top to bottom and from front to back, and the rear baffle 13 is inclined from top to bottom and from back to front. Since the seamless pipe requires a hexagonal packaging mode, the seamless pipe products located on the material rack 1 are stacked into a hexagonal shape for easy packaging. Therefore, the inclined front baffle 12 and rear baffle 13 can facilitate product stacking, and the existence of the front baffle 12 and the rear baffle 13 makes it difficult for the steel pipe 2 to roll forward and backward.

[0033] In addition, the connecting rod 5 includes a connecting section 51 and a contact section 52 that rotate with the mounting seat 6, and the matching seat 53 is located on the connecting section 51, and the contact section 52 is inserted into the connecting section 51 and is detachably connected to the connecting section 51 by means of threads, snaps, etc. Since the contact section 52 is detachably connected to the connecting section 51, when force is applied to the connecting rod 5 to drive the height change of the matching rod 41 and then drive the height change of the lifting rod 31, if a part of the connecting rod 5 is damaged, the connecting rod and the contact section 51 can be separated and the damaged part can be replaced, thereby reducing maintenance costs. In practice, according to the principle of leverage, the longer the length of the connecting rod 5, the smaller the force required to lift the connecting rod 5. Therefore, when the user thinks it is laborious to drive the connecting rod 5 downward or upward, the contact section 52 of the connecting rod 5 can be removed and replaced with a longer contact section 52 to increase the total length of the connecting rod 5, thereby making it more labor-saving to drive the connecting rod 5 to swing upward or downward.

[0034] The front side of the connecting section 51 is provided with a mounting ring 511 made of a deformable material such as rubber, and the contact section 52 is circumferentially provided with a plurality of mounting blocks 521. The mounting ring 511 is provided with mounting slots 5111 corresponding to each mounting block 521. When it is necessary to remove the contact section 52 from the connecting section 51, a force is applied outward to the mounting ring 511, thereby separating the connecting section 51 from the contact section 52. Similarly, for replacing a new contact section 52, a force is applied outward to the mounting ring 511 again, thereby allowing each mounting block 521 to enter the corresponding mounting slot 5111, thereby achieving a stable connection between the connecting section 51 and the contact section 52.

[0035] Among them, it further includes a support base 7 and a limit platform 8. The hydraulic pump 3 and the hydraulic cylinder 4 are both located on the support base 7. The number of the limit platforms 8 is two and they are respectively located on the left and right sides of the support base 7. On the front and rear sides of each limit platform 8, limit blocks 81 protrude upward. Since the number of the limit platforms 8 is two and they are respectively located on the left and right sides of the support base 7, they can be located below the left and right sides of the steel pipe 2. And due to the existence of each limit block 81, the situation that the steel pipe 2 falls and slides forward and backward can be reduced, improving safety.

[0036] Preferably, the material rack 1 is made of hard nylon material. Hard nylon usually has relatively high hardness and rigidity, which makes them not easily deformed when bearing heavy loads. And since hard nylon is non-metallic, it will not undergo electrochemical changes with stainless steel, thus reducing or eliminating the risk of ferrite contamination.

[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
