Description

Technical Field

[0001] This utility model relates to the field of pressure vessel welding operation technology, and in particular to an aerial platform for high-altitude welding of pressure vessels. Background Technology

[0002] When welding large pressure vessels, due to their large size, welding requires working at heights. Generally, welders climb ladders onto the body of the large pressure vessel to carry out the welding work.

[0003] In the prior art, Chinese Patent Publication No. CN218894364U discloses a construction support for civil engineering, including a construction support frame with an adjustment structure and a support structure located below it. The adjustment structure includes two first collars, the inner surfaces of which are rotatably connected to the outer surface of the construction support frame. Two second collars are rotatably mounted on the outer surface of the construction support frame. A rocker arm is fixedly installed on opposite sides of both the two first collars and the two second collars. A square frame is fixedly installed on the outer surface of the construction support frame. This construction support frame for civil engineering, by incorporating the adjustment structure, achieves the purpose of adjusting the angle of the support structure, facilitating adjustments according to specific conditions and improving the applicability of the support structure.

[0004] However, in actual use, the top of the pressure vessel is usually curved, making it difficult for the top of the construction support to connect with the top of the pressure vessel. This makes it inconvenient for workers to directly construct on the pressure vessel, posing certain potential risks during use. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide an aerial platform for high-altitude welding of pressure vessels, which facilitates high-altitude welding operations on pressure vessels and improves the safety of high-altitude operations.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an aerial platform for high-altitude welding of pressure vessels, including a support frame, a platform fixedly connected to the top of the support frame, an inlet and outlet opened inside the platform, an extension steel plate fixedly connected to one end of the platform, a screw threadedly connected inside the extension steel plate, a handle fixedly connected to the top of the screw, a mounting plate rotatably connected to the bottom of the screw, a fixing seat sleeved on the outer surface of the mounting plate, and an arc-shaped suction cup fixedly connected to the bottom of the fixing seat.

[0007] By adopting the above technical solution, the support frame is moved to one side of the pressure vessel, and the height of the extension steel plate is slightly higher than the top of the pressure vessel, so that the extension steel plate can extend to the top of the pressure vessel. When in use, turning the handle drives the screw to rotate, thereby driving the mounting plate to descend, which in turn drives the arc-shaped suction cup to descend to the top of the pressure vessel. The arc-shaped surface makes it easy to fit the top of the pressure vessel. With continuous downward pressure, the air inside the arc-shaped suction cup is squeezed out and adsorbed onto the top of the pressure vessel, thereby fixing it. The arc-shaped suction cup can be disassembled and replaced periodically to ensure the suction force, so that the extension steel plate can be firmly connected to the top of the pressure vessel, avoiding displacement during construction. Workers can enter and exit through the entrance and exit. The top is equipped with a safety railing, which makes it convenient for high-altitude welding operations on the pressure vessel and improves the safety of high-altitude operations.

[0008] A further feature of this invention is that the bottom of the extended steel plate has a sliding hole, and the top of the mounting plate is fixedly connected to a sliding rod.

[0009] By adopting the above technical solution, the sliding rod slides on the inner wall of the sliding hole when the mounting plate is raised or lowered, making it more stable.

[0010] A further feature of this invention is that the number of sliding rods is seven, and the seven sliding rods are evenly distributed.

[0011] By adopting the above technical solution, the guide force of the slide bar is evenly distributed at equal intervals.

[0012] A further feature of this invention is that a rotating ring is fixedly connected to the bottom of the screw, and a rotating sleeve is fixedly connected to the top of the mounting plate.

[0013] By adopting the above technical solution, the swivel can be driven on the inner wall of the rotating sleeve, which facilitates the up and down movement of the screw.

[0014] A further feature of this invention is that the internal thread of the fixing seat is connected with fixing bolts, and the number of fixing bolts is four.

[0015] By adopting the above technical solution, the fixing bolts connect the fixing seat to the mounting plate.

[0016] A further feature of this invention is that a small air pump is fixedly connected to the top of the mounting plate, and an air delivery pipe is fixedly connected to one end of the small air pump.

[0017] By adopting the above technical solution, when the fixation is released, a small air pump is started, and positive pressure air is delivered through the air supply pipe.

[0018] A further feature of this invention is that a sealing tube is fixedly connected to the bottom of the gas delivery pipe, and insertion holes are provided inside both the arc-shaped suction cup and the fixing base.

[0019] By adopting the above technical solution, the sealing tube is inserted into the socket without affecting the disassembly and replacement of the curved suction cup.

[0020] A further feature of this invention is that an elastic layer is fixedly connected to the outer surface of the sealing tube, and a damping layer is fixedly connected to the outer surface of the elastic layer.

[0021] By adopting the above technical solution, the elastic layer and damping layer prevent air leakage at the joint, and the curved suction cup allows air to be introduced to release the adsorption force.

[0022] A further feature of this invention is that a ladder is fixedly connected to the inner wall of the inlet and outlet, and a reinforcing frame is fixedly connected to the inner wall of the support frame.

[0023] By adopting the above technical solution, the ladder is used for workers to go up and down, and the reinforcement frame improves stability.

[0024] A further feature of this invention is that a caster wheel is fixedly connected to the bottom of the support frame, and a brake pad is provided inside the caster wheel.

[0025] By adopting the above technical solution, the swivel wheel increases its mobility, and the brake pads can restrict the swivel wheel when pressed.

[0026] The beneficial effects of this utility model are:

[0027] 1. This utility model, through the coordinated arrangement of a support frame, platform, inlet / outlet, extension steel plate, screw, handle, mounting plate, fixing seat, and arc-shaped suction cup, allows the support frame to move to one side of the pressure vessel during use. The height of the extension steel plate is slightly higher than the top of the pressure vessel, allowing the extension steel plate to extend to the top of the pressure vessel. During use, turning the handle drives the screw to rotate, which in turn lowers the mounting plate, causing the arc-shaped suction cup to descend to the top of the pressure vessel. The arc-shaped surface facilitates contact with the top of the pressure vessel. With continuous downward pressure, the air inside the arc-shaped suction cup is squeezed out and adsorbed onto the top of the pressure vessel, thus fixing it in place. The arc-shaped suction cup can be periodically disassembled and replaced to ensure the suction force, ensuring that the extension steel plate is firmly connected to the top of the pressure vessel, preventing displacement during construction. Workers can enter and exit through the inlet / outlet, and the top is equipped with a safety railing, thus facilitating high-altitude welding operations on the pressure vessel and improving the safety of high-altitude work.

The sliding rods are evenly distributed to guide the force, and the rotating ring can drive along the inner wall of the rotating sleeve, facilitating the up and down movement of the screw. The fixing bolts connect the fixing seat to the mounting plate. When the fixing is released, the small air pump is activated, and the air supply pipe delivers positive pressure air. The sealing pipe is inserted into the insertion hole without affecting the disassembly and replacement of the arc-shaped suction cup. The elastic layer and damping layer prevent air leakage at the insertion point. Air is introduced into the arc-shaped suction cup to release the suction force. The ladder is used for workers to go up and down, and the reinforcing frame improves stability. Attached Figure Description

[0038] Reference Figure 1-4 The top of the support frame 1 is fixedly connected to the platform 2. The platform 2 has an inlet and outlet 3. One end of the platform 2 is fixedly connected to the extension steel plate 4. The extension steel plate 4 is threadedly connected to the screw rod 5. The top of the screw rod 5 is fixedly connected to the handle 6. The bottom of the screw rod 5 is rotatably connected to the mounting plate 7. The outer surface of the mounting plate 7 is fitted with a fixing seat 8. The bottom of the fixing seat 8 is fixedly connected to the arc-shaped suction cup 9.

[0039] Specifically, the support frame 1 moves to one side of the pressure vessel, and the height of the extension steel plate 4 is slightly higher than the top of the pressure vessel, so that the extension steel plate 4 can extend to the top of the pressure vessel. When in use, the handle 6 is turned to drive the screw 5 to rotate, thereby driving the mounting plate 7 to descend, which in turn drives the arc-shaped suction cup 9 to descend to the top of the pressure vessel. The arc-shaped surface is easy to fit the top of the pressure vessel. With continuous downward pressure, the air inside the arc-shaped suction cup 9 is squeezed out and adsorbed on the top of the pressure vessel, thereby fixing it. The arc-shaped suction cup 9 can be disassembled and replaced regularly to ensure the adsorption force, so that the extension steel plate 4 can be firmly connected to the top of the pressure vessel, avoiding displacement during construction. Workers can enter and exit through the inlet and outlet 3. The top is equipped with a guardrail, which makes it convenient for high-altitude welding operations on the pressure vessel and improves the safety of high-altitude operations.

The bottom of the support frame 1 is fixedly connected with a universal wheel 23. The universal wheel 23 is provided with a brake pad inside.

[0042] Specifically, when the mounting plate 7 is raised or lowered, it drives the slide rod 11 to slide on the inner wall of the slide hole 10, making it more stable. The slide rod 11 is evenly distributed to guide the force. The rotating ring 12 can be driven on the inner wall of the rotating sleeve 13, which facilitates the up and down movement of the screw 5. The fixing bolt 14 connects the fixing seat 8 to the mounting plate 7. When the fixing is released, the small air pump 15 is started, and the air supply pipe 16 delivers positive pressure air. The sealing pipe 17 is inserted into the insertion hole 18 without affecting the disassembly and replacement of the arc suction cup 9.

[0043] In this invention, the support frame 1 moves to one side of the pressure vessel, and the height of the extension steel plate 4 is slightly higher than the top of the pressure vessel, allowing the extension steel plate 4 to extend to the top of the pressure vessel. During use, turning the handle 6 rotates the screw 5, which in turn lowers the mounting plate 7, causing the arc-shaped suction cup 9 to descend to the top of the pressure vessel. The arc-shaped surface facilitates contact with the top of the pressure vessel. With continuous downward pressure, the air inside the arc-shaped suction cup 9 is squeezed out and adsorbed onto the top of the pressure vessel, thus fixing it in place. The arc-shaped suction cup 9 can be periodically disassembled and replaced to ensure suction force, ensuring the extension steel plate 4 is firmly connected to the top of the pressure vessel, preventing displacement during construction. Workers can enter and exit through the inlet / outlet 3, and the top is equipped with a protective railing. This design facilitates high-altitude welding operations on pressure vessels, enhancing the safety of such operations. When the mounting plate 7 is raised or lowered, it drives the sliding rod 11 to slide along the inner wall of the sliding hole 10, resulting in greater stability. The sliding rod 11 is evenly distributed, ensuring uniform force distribution. The rotating ring 12 can move along the inner wall of the rotating sleeve 13, facilitating the up-and-down movement of the screw 5. The fixing bolt 14 connects the fixing seat 8 to the mounting plate 7. When the fixing is released, the small air pump 15 is activated, and the air supply pipe 16 delivers positive pressure air. The sealing pipe 17 is inserted into the insertion hole 18 without affecting the disassembly and replacement of the arc-shaped suction cup 9. The elastic layer 19 and damping layer 20 prevent air leakage at the insertion point. Air is introduced into the arc-shaped suction cup 9 to release the suction force.
