Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical production equipment, in particular to a special hanging basket for storage tank maintenance operations. Background Art

[0002] In the petrochemical equipment industrial chain, crude oil storage is an indispensable key step. Generally, during the storage process of steel storage tanks, their surfaces are prone to corrosion. Therefore, it is necessary to regularly carry out anti-corrosion maintenance on the storage tanks to increase the service life of the storage tanks.

[0003] When maintaining and repairing the storage tank, usually workers need to stand on a suspended hanging basket to carry out sandblasting or painting operations on the surface of the storage tank;

[0004] However, during the use of the current hanging basket, by installing guardrails around the hanging basket, it can protect the staff and avoid the risk of falling from a height. However, during the actual use process, since most of the guardrails of the hanging basket are of a fixed height, the existing guardrails cannot be applied to workers of different heights and cannot meet the actual use needs of the workers. If the guardrail is too high, it is easy to affect the construction operation of the workers, and vice versa, it will reduce the protection effect on the workers. And when the hanging basket is used up, the hanging basket is placed on the ground from a high altitude through the steel wire rope of the crane equipment. However, when the hanging basket contacts the ground, it will generate a certain impact force under the action of gravity and inertia, and the generated impact force will be transmitted to the bodies of the workers in the hanging basket, resulting in the possibility that the workers may be injured due to the impact force, thereby further reducing the safety protection effect of the hanging basket. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems that when the current hanging basket is in use, it is inconvenient to adjust the protection height of its guardrail, and the workers may also be injured due to the impact force when the hanging basket lands, thereby reducing the safety protection effect of the hanging basket, and to propose a special hanging basket for storage tank maintenance operations.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

Among them, an adjusting part is arranged in the cavity of the frame body, and the adjusting part is used to drive the guardrail to move up or down; a buffer plate, which is installed at the bottom of the frame body. Among them, an elastic member is arranged at the top of the buffer plate. When the frame body lands from the air, the impact force received by the frame body is weakened by the elastic force of the elastic member.

[0008] To facilitate the adjustment of the protective height of the guardrail, preferably, the adjusting part includes: a servo motor fixedly installed on the outer wall of the frame body. Wherein, a rotating rod is rotatably connected in the cavity of the frame body, one end of the rotating rod is fixedly connected to the output end of the servo motor, two support plates are fixedly connected in the cavity of the frame body, a screw rod is rotatably connected to the support plate, and bevel gears that mesh with each other are fixedly connected to both the screw rod and the rotating rod, and the guardrail is threadedly connected to the screw rod.

[0009] To buffer the landing of the hanging basket, preferably, the elastic member includes: a plurality of vertical rods fixedly connected to both sides of the top of the buffer plate. Wherein, a connecting plate is fixedly connected to the bottom of the frame body, a through hole is formed through the top of the connecting plate, the vertical rod is slidably connected in the through hole, a buffer spring is sleeved on the vertical rod, and both ends of the buffer spring are fixedly connected to the top of the buffer plate and the bottom of the connecting plate respectively.

[0010] To limit the connecting plate, further, a limiting block is fixedly connected to the top end of the vertical rod, and the diameter of the limiting block is larger than the inner diameter of the through hole in the connecting plate.

[0012] To filter the air entering the buffer airbag, still further, a filter element is detachably installed at the air inlet of the air inlet pipe.

[0013] Compared with the prior art, the present utility model provides a special hanging basket for storage tank maintenance operations, having the following beneficial effects:

[0014] 1. For this special hanging basket for storage tank maintenance operations, by starting the servo motor, the protective height of the guardrail can be quickly adjusted, so that it can be suitable for workers of different heights. By adjusting the guardrail to a height suitable for the workers themselves, it can not only meet the usage requirements of the workers, but also ensure the protective effect on the workers.

[0015] 2. For this special hanging basket for storage tank maintenance operations, when the hanging basket contacts the ground, through the combined use of the buffer plate, the connecting plate, the vertical rod and the buffer spring, the impact force generated when the hanging basket lands can be absorbed and weakened, and its energy can be converted into elastic potential energy, thereby buffering the hanging basket, reducing the impact force when the hanging basket lands, protecting the hanging basket body and the staff from damage, and thus improving the safety protection effect of the hanging basket.

[0028] Embodiment:

[0029] Referring to Figures 1-7 , the embodiment of the present utility model provides a special hanging basket for storage tank maintenance operations, including a frame body 1 with a cavity inside. Both sides of the frame body 1 are fixedly connected with hanging rings for facilitating the suspension of the hanging basket. It further includes: a guardrail 2, longitudinally slidably connected to the frame body 1. Among them, an adjusting part is arranged in the cavity of the frame body 1, and the adjusting part is used to drive the guardrail 2 to move up or down; a buffer plate 4, installed at the bottom of the frame body 1. Among them, an elastic member is arranged at the top of the buffer plate 4. When the frame body 1 lands from the air, the impact force received by the frame body 1 is weakened by the elastic force of the elastic member.

[0030] Specifically, during use, through the setting of the adjusting part, the protection height of the guardrail 2 can be quickly adjusted to be suitable for workers of different heights. By adjusting the guardrail 2 to a height suitable for the workers themselves, it can not only meet the use requirements of the workers, but also ensure the protection effect on the workers. And through the setting of the elastic member, the impact force generated when the hanging basket lands can be absorbed, reducing the impact force when the hanging basket lands, protecting the hanging basket body and the staff from damage, thereby improving the safety protection effect of the hanging basket.

[0031] The adjusting part includes: a servo motor 3, fixedly installed on the outer wall of the frame body 1. Among them, a rotating rod 31 is rotatably connected in the cavity of the frame body 1. One end of the rotating rod 31 is fixedly connected to the output end of the servo motor 3. Two support plates 32 are fixedly connected in the cavity of the frame body 1. A screw rod 33 is rotatably connected to the support plates 32. Both the screw rod 33 and the rotating rod 31 are fixedly connected with bevel gears 34 that mesh with each other. The guardrail 2 is threadedly connected to the screw rod 33.

[0032] Specifically, during use, by starting the servo motor 3, the output end of the servo motor 3 drives the rotating rod 31 and the bevel gear 34 to rotate, and drives the screw rod 33 to rotate. Under the action of the thread, the protective fence 2 moves up or down along the inner wall of the frame body 1, and the protective height of the protective fence 2 can be quickly adjusted.

[0033] The elastic member includes: a plurality of vertical rods 51, fixedly connected to both sides of the top of the buffer plate 4. The number of vertical rods 51 is 8 - 12, and preferably 10 in this solution. Among them, a connecting plate 5 is fixedly connected to the bottom of the frame body 1, and a through hole is formed through the top of the connecting plate 5. The vertical rod 51 is slidably connected in the through hole, and a buffer spring 52 is sleeved on the vertical rod 51. Both ends of the buffer spring 52 are fixedly connected to the top of the buffer plate 4 and the bottom of the connecting plate 5 respectively.

[0034] Specifically, during use, through the combined use of the buffer plate 4, the connecting plate 5, the vertical rod 51, and the buffer spring 52, the impact force generated when the hanging basket lands can be absorbed, thereby buffering the hanging basket.

[0035] A limiting block 6 is fixedly connected to the top end of the vertical rod 51, and the diameter of the limiting block 6 is greater than the inner diameter of the through hole on the connecting plate 5.

[0036] Specifically, through the setting of the limiting block 6, the connecting plate 5 can be limited, preventing the connecting plate 5 from disengaging from the vertical rod 51 under the elastic force of the buffer spring 52.

[0037] A buffer airbag 7 is fixedly installed between the buffer plate 4 and the connecting plate 5. One side of the buffer airbag 7 is communicated with an air inlet pipe 8, and the other side of the buffer airbag 7 is communicated with an exhaust pipe 9. Check valves are installed inside both the air inlet pipe 8 and the exhaust pipe 9.

[0038] Specifically, during use, when the hanging basket contacts the ground, the frame body 1 and the protective fence 2 will buffer downward under the action of the buffer plate 4, the connecting plate 5, and the buffer spring 52, and at the same time squeeze the buffer airbag 7, causing the air inside the buffer airbag 7 to be continuously discharged through the exhaust pipe 9 and gradually shrink;

[0039] When the frame body 1 and the protective fence 2 rebound upward following the buffer spring 52, the outside air will enter the buffer airbag 7 through the air inlet pipe 8, causing the buffer airbag 7 to quickly expand. Through the elastic force of the buffer spring 52, the continuous contraction and expansion of the buffer airbag 7 can cooperate with the buffer spring 52 to assist in buffering the hanging basket, further improving the buffering effect when the hanging basket lands, thereby being able to better protect the hanging basket body and the staff. And through the setting of the check valve, the air inlet pipe 8 can only intake air, while the exhaust pipe 9 can only exhaust air.

[0040] A filter element 10 is detachably installed at the air inlet of the air inlet pipe 8.

[0041] Specifically, through the setting of the filter element 10, the air entering the buffer airbag 7 can be filtered to prevent dust and impurities in the air from entering the buffer airbag 7.

[0042] Working principle: During the use of the special hanging basket for the maintenance operation of this storage tank, by starting the servo motor 3, the output end of the servo motor 3 drives the rotating rod 31 and the bevel gear 34 to rotate, and drives the screw rod 33 to rotate. Under the action of the thread, the guardrail 2 moves up or down along the inner wall of the frame body 1, and the protection height of the guardrail 2 can be quickly adjusted to be suitable for workers of different heights. By adjusting the guardrail 2 to a height suitable for the workers themselves, it can not only meet the use requirements of the workers, but also ensure the protection effect on the workers. After the adjustment is completed, the hanging basket is suspended in the air by the crane equipment. The worker stands on the suspended hanging basket and can perform sandblasting or painting operations on the surface of the storage tank;

[0043] When the maintenance operation of the storage tank is completed, the crane equipment drives the steel wire rope to place the hanging basket from a high altitude to the ground. When the hanging basket contacts the ground, through the combined use of the buffer plate 4, the connecting plate 5, the vertical rod 51 and the buffer spring 52, the impact force generated when the hanging basket lands can be absorbed and weakened, and its energy is converted into elastic potential energy, thereby buffering the hanging basket and reducing the impact force when the hanging basket lands, protecting the hanging basket body and the staff from damage, and further improving the safety protection effect of the hanging basket.

[0044] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
