Description

Technical Field

[0001] The utility model belongs to the technical field of safe welding of low-temperature storage tanks, and particularly relates to a high-altitude safe welding construction platform for vertical low-temperature storage tanks. Background Technique

[0002] Vertical low-temperature storage tanks are usually double-layer vacuum-insulated storage tanks. The inner tank is made of austenitic stainless steel, and the outer container is made of different materials according to the user's region, such as Q235-B, Q245R, or 345R as required. Heat-insulating materials, such as perlite sand or aluminum foil and heat-insulating cotton, are filled between the inner and outer layers, and the tank is evacuated. A vertical low-temperature storage tank mainly consists of an inner tank, a heat-insulating layer, and an outer tank. This structural design is to ensure the effective storage of low-temperature liquids while maintaining the integrity and insulation performance of the storage tank.

[0003] However, when welding a vertical low-temperature storage tank, workers use an ordinary working platform. Not only is it difficult to select the welding position during welding, but it takes a lot of time to adjust the position, reducing the work efficiency of the workers and delaying the project progress. Therefore, we propose a high-altitude safe welding construction platform for vertical low-temperature storage tanks. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a high-altitude safe welding construction platform for vertical low-temperature storage tanks. By starting the motor, the rotating column one can drive the runner to rotate on the inner wall of the slideway. Since the pulley one and the runner are in contact with the top and bottom of the slideway respectively, the runner can drive the whole device to move along the slideway when rotating, solving the problem that existing workers use an ordinary working platform. Not only is it difficult to select the welding position during welding, but it takes a lot of time to adjust the position, reducing the work efficiency of the workers and delaying the project progress.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a high-altitude safe welding construction platform for vertical low-temperature storage tanks, including a low-temperature storage tank. A slideway is fixedly connected to the inner wall of the low-temperature storage tank. A fixing ring is fixedly connected to one side of the inner wall of the low-temperature storage tank close to the slideway. A ladder is fixedly connected to the inner wall of the fixing ring. A moving block is arranged above the slideway. A motor is arranged on the back of the moving block. The output shaft on the back of the motor is fixedly connected to a rotating column one through a coupling. A runner is fixedly connected to the back of the rotating column one. The bottom of the runner is in contact with the inner wall of the slideway. A pulley one is in contact with the bottom of the slideway. When the runner rotates, it can drive the whole device to move along the slideway, enabling workers to conveniently select the welding position without spending a lot of time adjusting the working platform and improving the working effect of the workers.

[0007] Furthermore, a first connecting block is fixedly connected to the front surface of the moving block. A moving operation platform is fixedly connected to the bottom of the first connecting block. An anti-falling net is fixedly connected to the top of the moving operation platform. A rotating door is rotatably connected to the right side of the moving operation platform through a hinge. The anti-falling net can protect the staff and prevent them from accidentally falling when moving.

[0008] Furthermore, a moving groove is formed in the back surface of the moving block. A fixed block is fixedly connected to the top inner wall of the moving groove. The bottom of the fixed block is fixedly connected to the top of the motor. A limiting plate is fixedly connected to one side of the top inner wall of the moving groove close to the fixed block. The number of the limiting plates is two, and the two limiting plates are symmetrically arranged. The front surface of the motor is fixedly connected to the front surface of the inner wall of the moving groove. The first pulley is rotatably connected to the front surface of the inner wall of the moving groove through a pin shaft. The first pulley can make the moving block move more smoothly and prevent it from being stuck or misaligned when moving.

[0009] Furthermore, a second connecting block is fixedly connected to the bottom of the moving block. The number of the second connecting blocks is two, and the two second connecting blocks are symmetrically arranged. The second connecting blocks can make the moving block and the moving operation platform move more stably when moving, improving the overall stability of the device.

[0010] Furthermore, a fixed groove is formed in the back surface of the moving operation platform. A hanging cross bar is fixedly connected to the inner wall of the fixed groove. A storage box is fixedly connected to the bottom inner wall of the moving operation platform. The hanging cross bar allows the staff to hang the safety rope on its outer surface, which does not affect the staff's operation and also protects the staff.

[0011] Furthermore, a limiting block is fixedly connected to the bottom of the moving operation platform. A rotating hole is formed in the front surface of the limiting block. A second rotating column is in contact with the inner wall of the rotating hole. A second pulley is fixedly connected to the back surface of the second rotating column. The number of the second pulleys is two, and the two second pulleys are symmetrically arranged with the limiting block as the center. The second pulleys can reduce the pressure on the rotating wheel, protect the rotating wheel, and extend the service life of the equipment.

[0012] The utility model has the following beneficial effects:

[0013] 1. By setting the rotating wheel, specifically by starting the motor, the first rotating column can drive the rotating wheel to rotate on the inner wall of the slideway. Since the first pulley and the rotating wheel are in contact with the top and bottom of the slideway respectively, the rotating wheel can drive the whole device to move along the slideway when rotating, enabling the staff to conveniently select the welding position without spending a lot of time adjusting the operation platform, thus improving the work efficiency of the staff.

[0014] 2. The utility model enables workers to hang safety ropes on the hanging crossbar by arranging the hanging crossbar on the mobile working platform, which does not affect the normal operation of the workers. The anti-falling net can prevent the workers from falling when walking. The rotating door towards the internal switch can effectively reduce the risk when workers board the mobile working platform, making the workers safer during welding operations and reducing the occurrence of accidents.

[0015] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Please refer to Figures 1-5 As shown, the present utility model is a high-altitude safety welding construction platform for a vertical low-temperature storage tank, including a low-temperature storage tank 1. A slideway 11 is fixedly connected to the inner wall of the low-temperature storage tank 1. A fixing ring 111 is fixedly connected to one side of the inner wall of the low-temperature storage tank 1 close to the slideway 11. A ladder 112 is fixedly connected to the inner wall of the fixing ring 111. A moving block 2 is arranged above the slideway 11. A motor 31 is arranged on the back of the moving block 2. The output shaft on the back of the motor 31 is fixedly connected to a first rotating column 311 through a coupling. A runner 32 is fixedly connected to the back of the first rotating column 311. The bottom of the runner 32 is in contact with the inner wall of the slideway 11. A first pulley 33 is in contact with the bottom of the slideway 11. By setting the runner 32, specifically by starting the motor 31, the first rotating column 311 can drive the runner 32 to rotate on the inner wall of the slideway 11. Since the first pulley 33 and the runner 32 are respectively in contact with the top and bottom of the slideway 11, when the runner 32 rotates, the whole device can be driven to move along the slideway 11, enabling the staff to conveniently select the welding position without spending a lot of time adjusting the operation platform, thus improving the work efficiency of the staff.

[0026] A first connecting block 21 is fixedly connected to the front of the moving block 2. A moving operation platform 211 is fixedly connected to the bottom of the first connecting block 21. A fall-prevention net 212 is fixedly connected to the top of the moving operation platform 211. A rotating door 22 is rotatably connected to the right side of the moving operation platform 211 through a hinge.

[0027] A moving groove is formed in the back of the moving block 2. A fixing block 3 is fixedly connected to the top of the inner wall of the moving groove. The bottom of the fixing block 3 is fixedly connected to the top of the motor 31. A limiting plate 34 is fixedly connected to one side of the top of the inner wall of the moving groove close to the fixing block 3. The number of the limiting plates 34 is two. The two limiting plates 34 are symmetrically arranged. The front of the motor 31 is fixedly connected to the front of the inner wall of the moving groove. The first pulley 33 is rotatably connected to the front of the inner wall of the moving groove through a pin shaft.

[0028] A second connecting block 41 is fixedly connected to the bottom of the moving block 2. The number of the second connecting blocks 41 is two. The two second connecting blocks 41 are symmetrically arranged.

[0029] The back of the mobile working platform 211 is provided with a fixing groove, and the inner wall of the fixing groove is fixedly connected with a hanging cross bar 4. The bottom of the inner wall of the mobile working platform 211 is fixedly connected with a storage box 42. In the present utility model, by setting the hanging cross bar 4, specifically, through the setting of the hanging cross bar 4 on the mobile working platform 211, the staff can hang the safety rope on the hanging cross bar 4 without affecting the normal operation of the staff. Through the setting of the anti-falling net 212, it can prevent the staff from falling when walking. The rotating door 22 that rotates towards the inside can effectively reduce the risk when the staff climbs onto the mobile working platform 211, making the staff safer during welding operations and reducing the occurrence of accidents.

[0030] The bottom of the mobile working platform 211 is fixedly connected with a limiting block 5. The front of the limiting block 5 is provided with a rotating hole, and the inner wall of the rotating hole is in contact with a second rotating column 51. The back of the second rotating column 51 is fixedly connected with two second pulleys 511. The two second pulleys 511 are symmetrically arranged with the limiting block 5 as the center.

[0031] A specific application of this embodiment is as follows: The staff climbs onto the fixing ring 111 through the escalator 112, and then pushes the rotating door 22 inward to enter the mobile working platform 211. The rotating door 22 that rotates towards the inside can effectively reduce the risk when the staff climbs onto the mobile working platform 211. Then the staff hangs the safety rope on the hanging cross bar 4. At the same time, the setting of the anti-falling net 212 effectively avoids the safety hazard of the staff falling when moving, making the staff safer during welding operations and reducing the occurrence of accidents. Then, by starting the motor 31, the first rotating column 311 can drive the runner 32 to rotate in the slideway 11. The setting of the slideway 11 has a limiting effect on the runner 32 to prevent it from being misaligned when moving. Since the first pulley 33 and the runner 32 clamp the slideway 11, the rotation of the runner 32 will drive the moving block 2 and the mobile working platform 211 to move. The setting of the first pulley 33 can not only play a clamping role but also make the whole device move more smoothly. The whole device moves along the slideway 11, making it convenient for the staff to select the welding position without spending a lot of time adjusting the working platform, improving the working effect of the staff. The second pulley 511 arranged at the bottom of the mobile working platform 211 is in contact with the top of the fixing ring 111, which can reduce the pressure on the first pulley 33 and prevent it from being damaged by a large force, achieving the effect of extending the service life of the device and making the device move more smoothly when moving. After the staff finishes welding, the whole device can be moved to the position of the escalator 112 by starting the motor 31. Then, the safety rope is untied, and the staff gets off the mobile working platform 211 to the fixing ring 111 and then can go down to the ground from the escalator 112.
