Description

Technical Field

[0001] This utility model belongs to the technical field of aerial work platforms, specifically relating to an aerial work platform for steel structure engineering construction. Background Technology

[0002] High-altitude work usually refers to work at height, which is work performed by people at a certain height with a certain position as a reference. Generally, when working at height, people stand on a platform and are lifted by a lifting device.

[0003] The existing technology includes a high-altitude work platform for steel structure engineering construction, patent publication number CN214195482U. This patent comprises a rectangular support platform, pillars, guardrails, a lifting mechanism, and a traction mechanism. Pillars are welded to the four corners of the upper surface of the support platform, and guardrails are welded between adjacent pillars. The lifting mechanism includes a cylinder, a threaded cylinder, and a support rod. A cylinder is fixed to one end of the upper surface of the support platform. The advantages are: no manual handling is required when installing or lifting heavy objects, saving time and effort during construction, and providing strong safety. The detachable structure facilitates quick assembly and disassembly, reducing the occupied area. Material retrieval does not require lowering the work platform, greatly accelerating construction speed. However, while the device saves energy and facilitates material retrieval, workers need to extend their hands beyond the guardrails to operate tools. If their hands slip or they are careless, the tools may fall, and the lack of protection under the support platform poses a significant safety hazard, easily injuring workers passing by on the construction site.

[0004] Therefore, there is a need for a high-altitude work platform for steel structure engineering construction to solve the problem that existing technologies lack protection against falling tools on the support platform, which poses certain safety hazards. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a high-altitude work platform for steel structure engineering construction, including a support platform 1, and further including:

[0025] The guardrail 2 is fixedly installed on the top surface of the support platform 1. A storage cavity 8 is provided on one side of the support platform 1. A rotating column 9 is rotatably connected to one side of the inner wall of the storage cavity 8. A movable seat 10 is fixed on the outer surface of the rotating column 9. An anti-fall unit is provided on one side of the movable seat 10. The anti-fall unit is used to prevent tools from falling accidentally during construction operations. A snap-fit ​​component is provided on one side of the top surface of the support platform 1.

[0026] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the anti-drop unit includes:

[0027] The connecting shaft 3 is rotatably connected to one side of the movable seat 10. A baffle 4 is fixed on the outer surface of the connecting shaft 3.

[0028] It should be noted that during construction operations, the protective net 4 is used to protect the area below the construction workers, thereby preventing tools from accidentally falling and injuring passersby, and improving the safety of the aerial work platform.

[0029] Further as Figure 2As shown, it is worth noting that the card-connecting component includes:

[0030] L-shaped fixing plate 11 is fixed to the top surface of support platform 1. Movable rod 14 is movably passed through the top surface of L-shaped fixing plate 11. U-shaped limiting block 12 is fixed to the bottom end of movable rod 14. U-shaped limiting block 12 is engaged with movable seat 10. Spring 13 is sleeved on the outer surface of movable rod 14. One end of spring 13 is fixed to the surface of L-shaped fixing plate 11, and the other end of spring 13 is fixed to the top surface of U-shaped limiting block 12.

[0031] It is worth noting that the elastic force of the spring 13 causes the U-shaped limiting block 12 to be locked on the movable seat 10, thereby limiting the barrier net 4.

[0032] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that a handle 15 is fixed to the top of the movable rod 14, which facilitates the movement of the U-shaped limiting block 12; a throttle 5 is fixed to the end of the connecting shaft 3, which facilitates the rotation of the connecting shaft 3 to rewind the netting 4; a baffle 16 is inserted into one side of the inner wall of the storage cavity 8, and a lever 17 is fixed to one side of the baffle 16, which facilitates the sliding of the baffle 16 within the storage cavity 8.

At this time, the connecting shaft 3 and the support platform 1 are at a right angle. Then, the insert rod 6 is pulled to unfold the rolled-up net 4. The insert rod 6 is inserted into the slot of the card seat 7. At this time, the positioning rod 18 passes through the card seat 7 and the insert rod 6 to limit the insertion rod 6. Finally, under the elastic force of the spring 13, the U-shaped limiting block 12 is locked on the movable seat 10 to limit the rotating column 9 and maintain the stability of the net 4 in supporting protection. After construction, the net 4 can be stored and rotated into the storage cavity 8 for storage, reducing the space occupied.
