Description

Technical Field

[0001] The invention relates to the technical field of steel pipe hoisting equipment, in particular to a steel pipe hoisting device in a port container. Background Art

[0002] Steel pipe hoisting refers to the installation and transportation of steel pipes by cranes or lifting mechanisms. During the inspection or transportation process, various hoisting machines are used to lift equipment, workpieces or steel pipe materials to change their positions.

[0003] Among them, when the steel pipe is transported to the designated location by the container, it is necessary to use the lifting device to lift the steel pipe and move it to the designated location for subsequent transportation or use. However, the existing steel pipe will be bumpy during the container transportation process, causing the steel pipes loaded inside the container to rub against each other and generate static electricity. Static electricity can absorb dust in the air and tiny debris with opposite charges. The surface of the steel pipe is ordinary steel that has not been finely processed, and the surface of the steel pipe itself is relatively rough. This rough surface provides more attachment points for dust and debris, just like tiny "hooks", making it easier for dust and debris to be adsorbed on it, so that the surface of the steel pipe is more likely to accumulate dust, causing the subsequent lifting structure to slide when lifting the steel pipe, or even detachment;

[0004] At the same time, when the steel pipe is hoisted, the weight of the steel pipe itself or external wind force may cause the hoisted steel pipe to have an unstable center of gravity, shake or even fall off, which not only reduces the transportation efficiency of the steel pipe, but also endangers the personal safety of the staff. In view of this, we propose a steel pipe hoisting device in a port container. Summary of the invention

[0017] 1. In the steel pipe lifting device in the port container, the clamping and limiting structure first contacts the surface of the steel pipe and swings to wipe it, so that the position where the adsorption structure is to be adsorbed can be cleaned, and then the adsorption structure is driven to reel in and automatically clean the surface, so that the dust and debris on the surface of the adsorption structure can be cleaned before adsorption, to prevent dust or debris on the surface of the adsorption structure before adsorption, which affects the adsorption effect. Then the adsorption structure drives the clamping structure to remove the clamping with the clamping and limiting structure, so that the clamping and limiting structure can better clamp and limit the subsequent steel pipes, to prevent the steel pipes from shifting during the lifting process, thereby improving production efficiency.

[0029] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Among them, after the steel pipe is transported to the designated location by the container, it is necessary to use the lifting device to lift the steel pipe and move it to the designated location for subsequent transportation or use. However, the existing steel pipe will be bumpy during the container transportation process, causing the steel pipes loaded inside the container to rub against each other and generate static electricity. Static electricity can absorb dust in the air and tiny debris with opposite charges. The surface of the steel pipe is ordinary steel that has not been finely processed, and the surface of the steel pipe itself is relatively rough. This rough surface provides more attachment points for dust and debris, just like tiny "hooks", making it easier for dust and debris to be adsorbed on it, so that the surface of the steel pipe is more likely to accumulate dust, causing the subsequent lifting structure to slide when lifting the steel pipe, or even detachment.

[0031] At the same time, when the steel pipe is hoisted, the weight of the steel pipe itself or external wind force may cause the hoisted steel pipe to become unstable and shake or even fall off, which not only reduces the transportation efficiency of the steel pipe, but also endangers the personal safety of the staff. For the embodiments of the present invention, please refer to Figures 1 to 8 A steel pipe hoisting device in a port container comprises a shell 1, a sliding bearing 2 for adjusting the position is arranged at the bottom of the shell 1, a clamping and limiting structure 300 for clamping the steel pipe is also arranged at the bottom of the shell 1, an adsorption structure 400 for adsorbing the steel pipe is arranged on the side of the clamping and limiting structure 300, and a clamping structure 500 for firmly clamping is arranged on the side of the clamping and limiting structure 300 away from the adsorption structure 400;

[0032] When the steel pipe is not lifted, the clamping and limiting structure 300 swings to drive the adsorption structure 400 to reel and automatically clean the surface, and at the same time drives the clamping structure 500 to remove the clamping connection with the clamping and limiting structure 300. When the steel pipe is lifted, the clamping and limiting structure 300 resets and swings to drive the adsorption structure 400 to reset and adsorb the steel pipe. At the same time, the clamping and limiting structure 300 can clamp the limited steel pipe and firmly clamp with the clamping structure 500.

[0033] The present invention takes into account that after the existing steel pipes are transported to the designated location by the container, they need to be lifted and moved to the designated location by means of a lifting device to facilitate subsequent transportation or use. However, the existing steel pipes will be bumpy during the transportation process by the container, causing the steel pipes loaded inside the container to rub against each other and generate static electricity. The static electricity can absorb dust in the air and tiny debris with opposite charges. In addition, the surface of the steel pipe is ordinary steel that has not been finely processed, and the surface of the steel pipe itself is relatively rough. This rough surface provides more attachment points for dust and debris, just like tiny "hooks", making it easier for dust and debris to be adsorbed on it, thereby making it easier for dust to accumulate on the surface of the steel pipe, making it difficult for the subsequent lifting structure to lift the steel pipe. Sliding or even detachment occurs. Therefore, the clamping and limiting structure 300 first contacts the surface of the steel pipe and swings to wipe it, so that the position to be adsorbed by the adsorption structure 400 can be cleaned, and then the adsorption structure 400 is driven to roll up and automatically clean the surface, so that the dust or debris on the surface of the adsorption structure 400 can be cleaned before adsorption, so as to prevent the adsorption structure 400 from having dust or debris on the surface before adsorption, which affects the adsorption effect. Then, the adsorption structure 400 drives the clamping structure 500 to remove the clamping connection with the clamping and limiting structure 300, so that the clamping and limiting structure 300 can better clamp and limit the subsequent steel pipe, and prevent the steel pipe from deviating during the lifting process, thereby improving production efficiency.

[0034] Moreover, when the existing steel pipe is hoisted, the lifted steel pipe may become unstable in gravity center, shake or even fall off due to the weight of the steel pipe itself or external wind force and other factors, which not only reduces the transportation efficiency of the steel pipe, but also endangers the personal safety of the workers. Therefore, the clamping and limiting structure 300 is reset and swung to drive the adsorption structure 400 to reset and adsorb the steel pipe, which effectively improves the cleaning of the adsorption structure 400 before adsorbing the steel pipe, thereby improving the adsorption effect. After that, the clamping and limiting structure 300 is reset to clamp the limited steel pipe and firmly connect it with the clamping structure 500, so as to realize clamping and limiting when lifting the steel pipe, prevent shaking and falling of the steel pipe after lifting, and also improve the clamping effect of the clamping and limiting structure 300 more firmly after lifting the steel pipe.

[0035] In order to achieve a more stable clamping of the steel pipe, the following specific structure needs to be disclosed in detail, please refer to Figure 1The bottom of the sliding bearing 2 is connected to each group of structures in a sliding manner, the top of the sliding bearing 2 is connected to the housing 1 in a fixed manner, and the housing 1 is connected to the external adjustment structure in a sliding manner;

[0036] First, the staff needs to install the two sides of the shell 1 with the external adjustment structure, and then the staff controls the shell 1 and moves the whole structure to the top of the steel pipe, and then controls the whole structure to slide on the surface of the sliding bearing 2, controls the subsequent clamping distance with the steel pipe, and then controls the whole structure to move toward the surface of the steel pipe, so as to facilitate the subsequent adsorption and clamping of the steel pipe;

[0037] In order to clean the surface of the steel pipe and facilitate the subsequent adsorption of the steel pipe, the following specific structure needs to be disclosed in detail, please refer to Figures 1 to 5 The clamping and limiting structure 300 includes a clamp 301, the top of the clamp 301 is rotatably connected to a limiting shaft 302, the limiting shaft 302 is fixedly connected to the bottom of the housing 1 through an adsorption structure 400, the top of the clamp 301 is also fixedly connected to a swing plate 303, the swing plate 303 is slidably connected to the bottom of the housing 1, and the side of the swing plate 303 is fixedly connected to a first wedge column 304;

[0038] After the whole set of structures moves toward the surface of the steel pipe, the two sets of clamps 301 will first contact the surface of the steel pipe. Since the surface of the steel pipe is an arc, after the two sets of clamps 301 contact the steel pipe, the two sets of clamps 301 will move away from each other and rotate around the limit axis 302. At that time, since the bottom of the clamps 301 is an arc and can fit the surface of the steel pipe, the two sets of clamps 301 can scrape the surface of the steel pipe when they move away from each other, remove burrs or debris on the surface of the steel pipe, and thus improve the subsequent adsorption effect of the adsorption structure 400 on the steel pipe. When the two sets of clamps 301 swing away from each other, the two sets of swing plates 303 will be driven to move closer to each other, and then the first wedge column 304 will be driven to contact the adsorption structure 400, which is convenient for the subsequent automatic cleaning of the adsorption structure 400.

[0039] Next, in order to realize the automatic cleaning of the adsorption structure 400 before adsorbing the steel pipe, the following specific structure needs to be disclosed in detail, please refer to Figures 1 to 5The adsorption structure 400 includes a limiting plate 401, which is fixedly connected to the bottom of the shell 1, and a suction plate 402 is fixedly connected inside the limiting plate 401. The middle part of the suction plate 402 is fixedly connected to the limiting plate 401, and a moving column 403 is slidably connected inside the limiting plate 401, and the moving column 403 is fixedly connected to the adsorption plate 402. A soft plate 406 is fixedly connected to the end of the moving column 403 away from the adsorption plate 402, and an L-shaped plate 407 is fixedly connected to the middle part of the soft plate 406. The L-shaped plate 407 is fixedly connected to the surface of the shell 1, and a second wedge-shaped column 404 is fixedly connected to the surface of the adsorption plate 402, and the second wedge-shaped column 404 is slidably connected to the limiting plate 401. A return spring 405 is fixedly connected to the outer ring surface of the second wedge-shaped column 404, and the bottom of the return spring 405 is fixedly connected to the limiting plate 401;

[0040] Then, when the two sets of swing plates 303 swing close to each other, the two sets of first wedge-shaped columns 304 will be driven to move close to each other. At that time, because the second wedge-shaped column 404 is higher than the first wedge-shaped column 304 and is adapted to the first wedge-shaped column 304, when the two sets of first wedge-shaped columns 304 swing close to each other, they will contact the second wedge-shaped column 404 and drive the second wedge-shaped column 404 to move toward the steel pipe. At that time, because the adsorption plate 402 is flexibly set, when the second wedge-shaped column 404 moves, it will slide inside the limit plate 401 and drive the two sets of adsorption plates 402 to gather inward. For specific status, please refer to Figure 8 , so that when the swing plate 303 is subsequently reset, the adsorption plate 402 will generate vibrations to automatically clean the dust or debris stuck on the surface;

[0041] Further, in order to realize that the clamping limit structure 300 is not engaged with the engaging structure 500, the adsorption structure 400 needs to disclose the following specific structure in detail, please refer to Figures 1 to 6 The clamping structure 500 includes an airbag 502, which is fixedly connected to the bottom of the shell 1, and a movable plate 503 is slidably connected to the top of the airbag 502. The movable plate 503 penetrates and is slidably connected to the inside of the shell 1. A limited block 504 is fixedly connected to the inside of the airbag 502. A hole that is adapted to the clamping block 501 is opened on the side of the airbag 502, and the clamping block 501 is fixedly connected to the side of the swing plate 303.

[0042] At that time, since the swing plate 303 is initially parallel to the clamp 301, the clamping block 501 fixedly connected to the swing plate 303 away from the first wedge-shaped column 304 is inside the airbag 502 and is clamped with the limit block 504. Since the middle of the airbag 502 is provided with a hole that is compatible with the clamping block 501, (the middle of the airbag 502 is only provided with a hole, but the airbag 502 is still in an inflated state, similar to a swimming ring), and the hole allows the inside of the clamping block 501 to slide a certain distance, please refer to the following movement process Figure 4When the adsorption plate 402 gathers inward, it will drive the moving column 403 to slide inside the limiting plate 401. Then, during the sliding process of the moving column 403, the soft plate 406 fixed on the top will be curved (similar to an inverted U shape) due to the pulling force of the moving column 403. For details, please refer to Figure 8 , please combine the following exercise process Figure 5 and Figure 8 When the soft plate 406 is in an arc shape, it will drive the moving plate 503 to slide in the hole opened in the middle of the airbag 502, and then the moving plate 503 will contact the clamping block 501 and drive the clamping block 501 to pass over the limiting block 504, so that the clamping block 501 swings with the swing plate 303, and facilitates the subsequent clamping structure 500 to clamp the limiting structure 300 firmly;

[0043] Furthermore, in order to realize the clamping and limiting of the steel pipe, the clamping and limiting structure 300 needs to disclose the following specific structure in detail, please refer to Figures 1 to 5 The clamp 301, the limit shaft 302, the swing plate 303 and the first wedge-shaped column 304 are symmetrically arranged in two groups along the transverse center of the housing 1. The clamp 301 is arc-shaped and adapted to the steel pipe. The top of the swing plate 303 is slidably connected to the bottom of the housing 1 and is telescopically arranged.

[0044] After the two groups of clamps 301 move away from each other along the steel pipe surface by the maximum swing distance, the clamps 301 are at the widest position of the steel pipe. Since the limit shaft 302 is provided with a torsion spring, the clamps 301 will lose the offset force after contacting the widest position of the steel pipe surface. Therefore, the torsion spring provided on the limit shaft 302 surface will drive the two groups of clamps 301 to reset and rotate, and clamp and limit with the steel pipe, so as to further prevent shaking when lifting the steel pipe. Then, when the clamps 301 reset and swing, the swing plate 303 will be driven to reset and swing and be parallel to the clamps 301, so as to facilitate the subsequent clamping and limiting of the clamping structure 500 and the clamping and limiting structure 300.

[0045] Next, in order to realize the automatic cleaning of dust and debris stuck on the surface of the adsorption structure 400, the following specific structure needs to be disclosed in detail, please refer to Figures 1 to 5 The adsorption plate 402 is flexibly arranged, and two groups of second wedge-shaped columns 404 and return springs 405 fixedly connected to the top of the adsorption plate 402 are symmetrically arranged along the center of the limiting plate 401, and four groups of movable columns 403 fixedly connected to the top of the limiting plate 401 are arranged along the dead angle of the limiting plate 401;

[0046] When the two groups of swing plates 303 are reset and swung, the first wedge-shaped columns 304 of the two groups are driven to reset and swung, and then the first wedge-shaped columns 304 will not contact the second wedge-shaped columns 404, so that the second wedge-shaped columns 404 are automatically reset under the limit of the reset spring 405, and drive the adsorption plate 402 to gather inward and be parallel. Since the reset spring 405 is elastic, a slight vibration will be generated when the reset spring 405 is reset, and then the adsorption plate 402 is driven to vibrate, so that the dust or debris stuck on the surface of the adsorption plate 402 is automatically cleaned when it is used for a long time, effectively improving the effect of the adsorption plate 402 in adsorbing the surface of the steel pipe, and then the adsorption plate 402 will contact the surface of the steel pipe, and the adsorption plate 402 is set to be self-priming;

[0047] Then, in order to achieve a clamping effect that is stable on the clamping limit structure 300, the clamping structure 500 needs to disclose the following specific structure in detail, please refer to Figures 1 to 6 , the clamping block 501, the airbag 502, the movable plate 503 and the limit block 504 are symmetrically arranged in two groups along the transverse center of the housing 1, the surface of the clamping block 501 is arranged in an arc shape, the limit block 504 clamped on the surface of the clamping block 501 is fixedly connected to the hole when the airbag 502 is opened and closed, and the bottom of the movable plate 503 slidably connected inside the airbag 502 is provided with a protrusion;

[0048] When the swing plate 303 is reset and swung, the clamping block 501 will be driven to move close to the hole set in the middle of the airbag 502, and then the middle of the airbag 502 will be impacted by the clamping block 501 and drive the airbag 502 to expand, and driven by the impact of the clamping block 501, it will go over the limit block 504, so as to realize the overall clamping of the swing plate 303, and prevent the clamp 301 fixedly connected to the bottom of the swing plate 303 from detaching when clamping the limit steel pipe, so as to further improve the clamping effect, and then the expansion of the airbag 502 will drive the movable plate 503 to move in the direction of the L-shaped plate 407, and then drive the soft plate 406 to reset, so as to facilitate the subsequent soft plate 406 to deform the adsorption plate 402 again to clean dust;

[0049] In order to improve the stability of the steel pipe after lifting, the following specific structure needs to be disclosed in detail, please refer to Figure 1 The clamping and limiting structure 300, the adsorption structure 400 and the snap-on structure 500 are respectively arranged in three groups along the surface of the shell 1, so as to better clamp and limit the shaking generated when the steel pipe is transported, and prevent the steel pipe from falling off when being transported.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
