Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a safety lifting device for building construction. Background Technology

[0002] In the construction industry, lifting devices are core equipment for transporting personnel and materials, and their safety and reliability directly affect construction progress and personnel safety. Among them, scissor lifts, with their compact structure, smooth lifting, and strong load-bearing capacity, have become one of the most widely used lifting devices in construction.

[0003] However, due to the presence of the scissor lift, the lifting platform of a scissor lift device generally has a certain base height. This design requires personnel to climb to access the platform and then jump down from a height after completing their work. This process not only poses a risk of falls due to instability during climbing, but the impact of the jump can also easily cause joint injuries, especially in complex construction environments and when personnel are fatigued, making the safety hazards even more pronounced. To facilitate workers' access to and from the lifting platform and reduce the safety risks during the process, we propose a safety lifting device for construction. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a safety lifting device for construction work, which facilitates workers' access to and from the lifting platform and reduces safety risks during the process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] Please see Figures 1-5This utility model provides a technical solution: a safety lifting device for construction, including a base 1, a lifting platform 3 above the base 1, a lifting component that drives the lifting platform 3 to rise and fall on the base 1, and a protective component for protecting workers on the lifting platform 3.

[0023] The protective assembly includes several sets of mounting rods 9, which are fixedly installed on the lifting platform 3. A mounting frame 4 is rotatably sleeved on the outside of the mounting rods 9. Several sets of rotating plates 5 are rotatably installed on the mounting frame 4. A rotating mechanism that drives the rotating plates 5 to rotate is installed on the mounting frame 4. A fixing mechanism that fixes the mounting frame 4 on the lifting platform 3 is installed on the lifting platform 3.

[0024] During operation, the mounting frame 4 is fixed to the lifting platform 3 by the fixing mechanism. At this time, the rotating plate 5 is in a vertical position, which protects the personnel and objects in the lifting platform 3. The lifting assembly moves the lifting platform 3 to a suitable position for operation. When personnel need to go up or down the lifting platform 3, the lifting platform 3 is lowered to the lowest point, the fixing of the mounting frame 4 is released, and the mounting frame 4 is rotated away from the lifting platform 3. During this process, the rotating plate 5 rotates under the action of the rotating mechanism until the rotating plate 5 rotates to a horizontal position, so that multiple sets of rotating plates 5 are combined to form a ladder. Workers can go up and down the lifting platform 3 through the ladder, avoiding the safety risks caused by climbing, jumping and other actions, and ensuring the personal safety of personnel.

[0025] The rotating mechanism includes a fixed gear 15, which is fixedly sleeved on the outside of the mounting rod 9. A rotating gear 23 is rotatably mounted on the inner wall of the mounting frame 4, and the rotating gear 23 meshes with the fixed gear 15. A toothed plate 16 is slidably connected to the inner wall of the mounting frame 4, and the toothed plate 16 meshes with the rotating gear 23. A driven gear 17 is fixedly connected to one end of the rotating plate 5 near the toothed plate 16, and the driven gear 17 meshes with the toothed plate 16. A rotating mechanism that limits the rotation angle of the rotating plate 5 is mounted on the mounting frame 4.

[0026] The mounting bracket 4 rotates, causing the rotating gear 23 to rotate around the fixed gear 15. The meshing of the fixed gear 15 and the rotating gear 23 causes the rotating gear 23 to rotate, which in turn causes the gear plate 16 to move, making the driven gear 17 rotate, and thus causing the rotating plate 5 to rotate.

[0027] The rotating mechanism includes several sets of rotating blocks 19. The rotating blocks 19 are fixedly connected to the end of the rotating plate 5 away from the driven gear 17. Several sets of fixed blocks 18 corresponding to the rotating blocks 19 are fixedly connected to the inner wall of the mounting bracket 4.

[0028] The rotating plate 5 rotates, causing the rotating block 19 to rotate. When the rotating plate 5 rotates to a horizontal position, the rotating block 19 abuts against the fixed block 18, preventing the rotating plate 5 from continuing to rotate.

[0029] The fixing mechanism includes several sets of baffles 6, which are fixedly installed on the lifting platform 3. The side of the baffle 6 closest to the mounting frame 4 abuts against the mounting frame 4. Several sets of limiting plates 21 are rotatably installed on the top of the mounting frame 4. Several sets of limiting grooves corresponding to the limiting plates 21 are opened on the lifting platform 3. Several sets of sliding covers 10 are slidably connected to the top of the lifting platform 3. Connecting screws 20 are threadedly installed on the sliding covers 10. A knob 11 is fixedly connected to the top of the connecting screws 20. Several sets of threaded holes matching the connecting screws 20 are opened on the lifting platform 3.

[0030] Make the mounting bracket 4 press against the baffle 6. At this time, the limiting plate 21 is aligned with the limiting groove. Rotate the limiting plate 21 to make it enter the limiting groove. Slide the sliding cover 10 to the top of the limiting plate 21. Rotate the knob 11 to drive the connecting screw 20 to rotate, so that the connecting screw 20 enters the threaded hole, thereby fixing the position of the sliding cover 10, and thus fixing the position of the limiting plate 21, so that the mounting bracket 4 is fixed on the lifting platform 3.

[0031] The lifting assembly includes a motor 7, which is fixedly installed at the bottom of the inner cavity of the base 1. A bidirectional screw 12 is fixedly connected to the output end of the motor 7. The end of the bidirectional screw 12 away from the motor 7 is rotatably connected to the inner wall of the base 1. Two sets of mounting plates 13 are slidably connected to the inner wall of the base 1. The bidirectional screw 12 is threaded through the mounting plate 13. A scissor lift 2 is hinged to the top of the mounting plate 13. Two sets of connecting plates 14 corresponding to the mounting plates 13 are slidably connected to the bottom of the lifting platform 3. The bottom of the connecting plate 14 is hinged to the scissor lift 2.

[0032] The starter motor 7 drives the bidirectional screw 12 to rotate, causing the two sets of mounting plates 13 to move closer or further apart. Under the action of the scissor lift 2, when the mounting plates 13 move closer together, the lifting platform 3 rises; when the mounting plates 13 move further apart, the lifting platform 3 falls.

[0033] A push handle 22 is fixedly connected to the top of the base 1, and several sets of casters 8 are fixedly connected to the bottom of the base 1.

[0034] Working principle: During operation, the mounting frame 4 is pressed against the baffle 6, at which point the limiting plate 21 is aligned with the limiting groove. The limiting plate 21 is rotated to enter the limiting groove, and the sliding cover 10 slides to the top of the limiting plate 21. The knob 11 is rotated to drive the connecting screw 20 to rotate, allowing the connecting screw 20 to enter the threaded hole, thus fixing the position of the sliding cover 10 and the limiting plate 21. This fixes the mounting frame 4 on the lifting platform 3. At this time, the rotating plate 5 is in a vertical state, providing protection for personnel and items in the lifting platform 3. The starting motor 7 drives the bidirectional screw 12 to rotate, causing the two sets of mounting plates 13 to move closer or further apart. Under the action of the scissor lift 2, when the mounting plates 13 move closer together, the lifting platform 3 rises; when the mounting plates 13 move further apart, the lifting platform 3 descends, moving the lifting platform 3 to a suitable position for operation. When personnel need to go up or down the lifting platform 3, the lifting platform 3 is lowered to its lowest point, the fixing to the mounting frame 4 is released, and the mounting frame 4 is rotated away from the lifting platform 3. The rotation of the mounting frame 4 drives the rotating gear 23 to rotate around the fixed gear 15. Due to the meshing of the fixed gear 15 and the rotating gear 23, the rotating gear 23 rotates on its own, driving the gear plate 16 to move, causing the driven gear 17 to rotate, driving the rotating plate 5 to rotate. The rotation of the rotating plate 5 drives the rotating block 19 to rotate. When the rotating plate 5 rotates to a horizontal state, the rotating block 19 abuts against the fixed block 18, preventing the rotating plate 5 from continuing to rotate. Multiple sets of rotating plates 5 are combined to form a staircase. Workers can go up and down the lifting platform 3 through the staircase, avoiding the safety risks caused by climbing, jumping and other actions, and ensuring the personal safety of personnel.
