Description

Technical Field

[0001] This application belongs to the technical field of aerial work platforms, and specifically relates to an aerial work platform for air-conditioning refrigeration maintenance operations. Background Art

[0002] An aerial work platform is a device used for working at high altitudes and is widely used in industries such as construction, maintenance, installation, and other industries that require working at a certain height. The outdoor unit of an air-conditioning refrigerator is sometimes placed at a high place and requires maintenance operations. Therefore, an aerial work platform is needed to move the staff to the corresponding position for operation.

[0003] Aerial work platforms usually use hoisting and traction from above to the corresponding position, and in relatively low areas, some use elevators to lift. Sometimes, some components need to be replaced and cleaned during air-conditioning refrigeration maintenance. Some of the replaced components need to be moved to the ground. Usually, heavy objects are towed after binding the towing rope. And some components are also heavy and large in size, and need to be carried by the staff onto the work platform and taken back together. In the case of hoisting and traction, the handling of components will cause shaking, which poses a great safety hazard to the staff.

[0004] Therefore, for traditional aerial work platforms, when disassembling the outdoor unit of an air-conditioning refrigerator, it needs to be moved from above into the platform. The upper half of the staff's body will extend out of the platform, which is inconvenient for handling, and there will be shaking when reaching the bottom. Summary of the Utility Model

[0005] The purpose of this application is to provide an aerial work platform for air-conditioning refrigeration maintenance operations to solve the problems of the traditional aerial work platform mentioned above, where when disassembling the outdoor unit of an air-conditioning refrigerator, it needs to be moved from above into the platform, the upper half of the staff's body will extend out of the platform, which is inconvenient for handling, and there will be shaking when reaching the bottom.

[0006] The technical solution adopted in this application is as follows: An aerial work platform for air-conditioning refrigeration maintenance operations includes a bottom support frame. A support column is welded to the outer surface of the bottom support frame. A support crossbeam is welded to the outer surface of the support column near the upper side. A fixed column is welded to the outer surface of the bottom support frame corresponding to the support crossbeam. An activity groove is welded to the outer surface of the support crossbeam. An activity groove is also welded to the outer surface of the bottom support frame at the corresponding position. An activity column is movably connected to the inner surface of the activity groove. An adjustment rod is movably connected to the outer surface of the activity column. An anti-falling net is fixedly connected to the outer surface of the adjustment rod. The upper outer surface of the anti-falling net is welded to the support crossbeam. A fixed binding rope is movably sleeved on the outer surface of the activity column.

[0007] By adopting the above technical solutions, when the working platform needs to disassemble the outdoor unit of the air conditioner or displace components with relatively large dimensions, the adjusting rod is pulled up, the anti-falling net is moved upward, and the equipment is moved to the beam with enhanced load-bearing capacity. The adjusting rod is made of soft material, and the movable column can move left and right correspondingly, increasing the entry width, so that secondary traction is not required, reducing the risk factor. The support column and the bottom support frame provide a reference support for the fixation of the overall platform. The support beam and the fixed column reinforce the space at other positions, preventing accidents caused by workers hanging in the air. By binding with the ropes extended from the fixed binding ropes, the pulled-in components can be fixed, or the movable column and the anti-falling net can be penetrated and fixed, ensuring the overall stability of the platform and greatly reducing the uncontrollability of high-altitude operations.

[0008] In a preferred embodiment, a load-bearing frame is welded on the inner surface of the bottom support frame, and a load-bearing net is welded on the inner surface of the bottom support frame corresponding to the load-bearing frame.

[0009] By adopting the above technical solutions, the bottom support frame, the load-bearing frame, and the load-bearing net form the bottom support main body, which is overall meshed, ensuring support while reducing the overall weight of the platform.

[0010] In a preferred embodiment, an upper support handrail is welded on the outer surface of the upper end of the support column, and a support crossbar is welded on the outer surface of the support column on the side away from the anti-falling net.

[0011] By adopting the above technical solutions, the upper support handrail supports the workers above, and the other side of the support crossbar provides support for the workers.

[0012] In a preferred embodiment, a fixed seat is welded on the upper surface of the upper support handrail, and an extended support rod is arranged on the inner surface of the fixed seat.

[0013] By adopting the above technical solutions, the extended support rod rotates at the fixed seat and extends out. The front end of the extended support rod extends out, facilitating the support of the platform from the outside and increasing the stability of the platform.

[0014] In a preferred embodiment, a bottom traction block is welded on the outer surface of the support column on the side away from the bottom support frame, and a guiding block is welded on the upper outer surface of the support column corresponding to the bottom traction block.

[0015] By adopting the above technical solutions, the bottom traction block provides a traction support position for the platform at the bottom, and the guiding block guides the traction rope to ensure better support.

[0016] In a preferred embodiment, a side railing is welded on the upper surface of the side of the bottom support frame, and a placement box is fixedly connected to the upper outer surface of the side railing.

[0017] By adopting the above technical solution, the side rail provides support for the staff on the side to ensure the safety of the staff. The staff can place tools in the placement box for convenient use.

[0018] In a preferred embodiment, a fixing ring is movably sleeved on the outer surface of the support cross beam away from the anti-falling net side. A traction rope is welded on the outer surface of the fixing ring, and a protection main body is fixedly connected to the outer surface of one end of the traction rope away from the anti-falling net.

[0019] By adopting the above technical solution, the fixing ring is sleeved on the support cross beam. Through the traction of the traction rope and the protection main body, the staff is integrated with the platform to prevent the staff from falling.

[0020] In a preferred embodiment, a shoulder strap is fixedly connected to the upper outer surface of the protection main body, and a waist strap is fixedly connected to the lower outer surface of the protection main body.

[0021] By adopting the above technical solution, there are magic tapes on the front and back surfaces of both ends of the shoulder strap. The waist strap is fixed to the corresponding outer surface of the waist strap by disassembling the magic tape. The staff wraps and fixes the shoulder strap around the shoulders and fixes the waist strap around the waist.

[0022] In summary, due to adopting the above technical solution, the beneficial effects of the present application are as follows:

[0023] In the present application, when the working platform needs to disassemble the air conditioner outdoor unit or displace relatively large-sized parts, the adjusting rod is pulled up to move the anti-falling net upward, and the equipment is moved to the cross beam with enhanced load-bearing capacity. The adjusting rod is made of a soft material, and the movable column can move left and right correspondingly, increasing the entry width, so that secondary traction is not required, reducing the risk coefficient. The support column cooperates with the bottom support frame to provide a reference support for the fixation of the overall platform. The support cross beam and the fixed column reinforce other position spaces to prevent the staff from hanging in the air and causing accidents. The parts pulled in can be fixed by the ropes extended from the fixed binding ropes, or the movable column and the anti-falling net can be penetrated and fixed, ensuring the overall stability of the platform and greatly reducing the uncontrollability of high-altitude operations.

[0031] Embodiment:

[0032] Referring to Figures 1-3 , an aerial work platform for air-conditioning refrigeration maintenance operations includes a bottom support frame 1. A support column 2 is welded to the outer surface of the bottom support frame 1. A support cross beam 3 is welded to the outer surface of the support column 2 near the upper side. A fixed column 4 is welded to the outer surface of the bottom support frame 1 corresponding to the support cross beam 3. A movable groove 6 is welded to the outer surface of the support cross beam 3. A movable groove 6 is also welded to the outer surface of the bottom support frame 1 at the corresponding position. An inner surface of the movable groove 6 is movably connected to a movable column 5. An outer surface of the movable column 5 is movably connected to an adjusting rod 7.

A fixed binding rope 15 is movably sleeved on the outer surface of the movable column 5.

[0033] When the work platform needs to disassemble the air conditioner outdoor unit or displace relatively large-sized parts, then pull up the adjusting rod 7 to move the anti-falling net 8 upward, move the equipment to the cross beam with enhanced load-bearing capacity. The adjusting rod 7 is made of a flexible material, and the corresponding movable column 5 can move left and right, increasing the entry width, so that secondary traction is not required, reducing the risk factor. The support column 2 and the bottom support frame 1 provide a reference support for the fixation of the overall platform. The support cross beam 3 and the fixed column 4 reinforce other positions in the space to prevent accidents caused by the staff hanging in the air. The parts pulled in can be fixed by binding with the ropes extended from the fixed binding rope 15, or the movable column 5 and the anti-falling net 8 can be penetrated and fixed to ensure the overall stability of the platform, greatly reducing the uncontrollability of high-altitude operations.

[0034] Refer to Figure 4 , a load-bearing frame 23 is welded to the inner surface of the bottom support frame 1, and a load-bearing net 24 is welded to the inner surface of the bottom support frame 1 corresponding to the load-bearing frame 23.

[0035] The bottom support frame 1, the load-bearing frame 23, and the load-bearing net 24 form the bottom support body, which is overall meshed to ensure support while reducing the overall weight of the platform.

[0036] Refer to Figures 1-3 , an upper support handrail 9 is welded to the outer surface of the upper end of the support column 2, and a support cross bar 10 is welded to the outer surface of the support column 2 on the side away from the anti-falling net 8.

[0037] The upper support handrail 9 supports the staff above, and the other side of the support cross bar 10 provides support for the staff.

[0038] Refer to Figures 1-3 , a fixing seat 16 is welded to the upper surface of the upper support handrail 9, and an extending support rod 17 is arranged on the inner surface of the fixing seat 16.

[0039] The extending support rod 17 rotates at the fixing seat 16 and extends out. The front end of the extending support rod 17 extends out, which is convenient for supporting the platform externally and increases the stability of the platform.

[0040] Refer to Figures 1-3 , a bottom traction block 11 is welded to the outer surface of the support column 2 on the side away from the bottom support frame 1, and a guiding block 12 is welded to the upper end of the outer surface of the support column 2 corresponding to the bottom traction block 11.

[0041] The bottom traction block 11 provides a traction support position for the platform at the bottom, and the guiding block 12 guides the traction rope to ensure better support.

[0042] Refer to Figures 1-3 , a side railing 13 is welded to the upper surface of the side edge of the bottom support frame 1, and a placement box 14 is fixedly connected to the outer surface of the upper end of the side railing 13.

[0043] The side railing 13 provides support for the staff on the side to ensure the safety of the staff. The staff can place tools in the placement box 14 for convenient use.

[0044] Refer to Figures 1-3 , a fixing ring 18 is movably sleeved on the outer surface of the support cross beam 3 away from the anti-falling net 8, a traction rope 19 is welded to the outer surface of the fixing ring 18, and a protection main body 20 is fixedly connected to the outer surface of one end of the traction rope 19 away from the anti-falling net 8.

[0045] The fixing ring 18 is sleeved on the support cross beam 3, and through the traction of the traction rope 19 and the protection main body 20, the staff and the platform are integrated to prevent the staff from falling.

[0046] Referring to Figures 1-3 , a shoulder strap 21 is fixedly connected to the outer surface of the upper end of the protection main body 20, and a waist belt 22 is fixedly connected to the outer surface of the lower end of the protection main body 20.

[0047] Both the front and back surfaces of the two ends of the shoulder strap 21 are provided with magic tapes. The waist belt 22 is respectively fixed to the corresponding outer surfaces of the waist belt 22 by disassembling the magic tapes. The staff wraps and fixes the shoulder strap 21 around the shoulders and fixes the waist belt 22 around the waist.

[0048] The implementation principle of an embodiment of the high-altitude working platform for air-conditioning refrigeration maintenance operation in this application is as follows:

[0049] In this application, only the platform end is described. The load-bearing end is the same as the traditional prior art, and the traction or lifting method is adopted. When in use, for the personnel standing on the working platform, both the front and back surfaces of the two ends of the shoulder strap 21 are provided with magic tapes. The waist belt 22 is respectively fixed to the corresponding outer surfaces of the waist belt 22 by disassembling the magic tapes. The staff wraps and fixes the shoulder strap 21 around the shoulders and fixes the waist belt 22 around the waist. One side of the anti-falling net 8 of the working platform faces the outdoor unit of the wall-mounted air conditioner. The bottom support frame 1, the load-bearing frame 23, and the load-bearing net 24 form the bottom support main body, and there are holes on the side to facilitate the penetration of ropes for fixing and other operations. The staff places tools in the placement box 14 and performs relevant operations above the upper support handrail 9. In the case where the outdoor unit of the air conditioner needs to be disassembled or relatively large-sized parts need to be displaced, the adjustment rod 7 is pulled up to move the anti-falling net 8 upward, and the equipment is moved to the beam with enhanced load-bearing. The movable column 5 can move left and right correspondingly, increasing the entry width, so that secondary traction is not required, reducing the risk factor. The support columns 2, the support cross beam 3, the fixed column 4, and the upper support handrail 9 form an overall support and protection to protect the staff on the working platform from falling and causing accidents. The ropes extended from the fixed binding ropes 15 can be used for binding, and can fix the pulled-in parts, or pass through and fix the movable movable column 5 and the anti-falling net 8 to ensure the overall stability of the platform, greatly reducing the uncontrollability of high-altitude operations.
