Description

Technical Field

[0001] This utility model belongs to the field of cement cover plate hoisting, specifically an irregular cement cover plate hoisting and lifting device. Background Technology

[0002] When constructing existing buildings, it is generally necessary to build molds. For example, structures such as air conditioning panels and outdoor bay windows require molds to be built before concrete is poured in place, allowing the concrete to solidify within the molds to form these structures. Due to the height of buildings, hoisting machines are typically used to lift and install the molds. Hoisting machines are suitable for hoisting operations in high-rise buildings, such as transporting various building materials and decoration materials.

[0003] A search revealed a Chinese patent (authorization announcement number CN115583608A) disclosing a hoisting device. This patented technology includes a three-dimensional motion mechanism, a lifting and traveling mechanism, and a suspension mechanism. The suspension mechanism is located within the three-dimensional motion mechanism and is used to drive the suspension mechanism to move along the lateral, longitudinal, and longitudinal directions of the hoisting device. The lifting and traveling mechanism includes a main lifting and traveling frame and a secondary lifting and traveling frame. The secondary lifting and traveling frame is slidably mounted on the main lifting and traveling frame, which is located within the three-dimensional motion mechanism. Using this invention, the position can be moved and adjusted, facilitating the hoisting of molds. Furthermore, the adjustment of mold positions is highly precise, improving the efficiency of mold installation.

[0004] However, existing technologies often cause cement slabs to sway when hoisted to high altitudes due to wind. Since cement slabs are heavy, they are prone to collapse if tilted. Even if they do not fall due to swaying, the swaying can still cause them to collide with buildings below. Therefore, this invention provides a hoisting and lifting device for irregular cement slabs. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problem that existing technologies cause cement slabs to sway when hoisted to high altitudes due to wind, and that cement slabs, being heavy, are prone to collapse if tilted, and that even if the cement slabs do not fall due to swaying, the swaying process can still cause them to collide with buildings at lower altitudes, this utility model proposes an irregular cement cover plate hoisting and lifting device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The irregular cement cover plate hoisting and lifting device of this utility model includes a support platform. Two side plates are symmetrically fixedly connected to the top of the support platform. A motor is fixedly connected to the outer wall of one of the side plates. The output end of the motor passes through the side plate and is fixedly connected to a first rotating shaft. Two winding rollers are symmetrically fixedly connected to the outer wall of the first rotating shaft. Pull ropes are wound around the outer walls of the two winding rollers. A material hopper is fixedly connected to one end of the two pull ropes. A reinforcing rope is fixedly connected to the top of the material hopper and the side away from the pull rope. One end of the reinforcing rope is fixedly connected to the pull rope. An anti-vibration component is provided at the bottom of the material hopper.

[0007] Start the motor to drive the first shaft to rotate clockwise, which in turn causes the two winding rollers to rotate clockwise, facilitating the release of the pull rope and moving the hopper downwards. Then, control the winding rollers to rotate counterclockwise via the motor to wind up the pull rope. As the pull rope is pulled, the hopper can move upwards to lift the cement slab.

[0008] Preferably, an electric telescopic rod is fixedly connected to one side of each of the two side plates, a fixed frame is fixedly connected to the output end of each of the two electric telescopic rods, a second rotating shaft is fixedly connected between the two fixed frames, a guide wheel is rotatably connected to the outer wall of the second rotating shaft, a limit shaft is fixedly connected to the outer wall of the fixed frame, and the limit shaft is slidably connected to the side plate.

[0009] The bottom of the pull rope is supported by the guide wheel. When the outside wind is strong, the fixed frame is moved towards the outer facade of the building by the electric telescopic rod. The guide wheel guides the hopper to move closer to the outer facade of the building, thereby reducing the impact of the wind on the hopper. The combination of the pull rope and the reinforcing rope allows the hopper to be closer to the outer facade of the building.

[0010] Preferably, the seismic component includes a mounting frame, with two first dampers symmetrically fixedly connected to the inner wall of the mounting frame. Each of the two first dampers has a first damping rod slidably connected inside. A ring frame is fixedly connected between the two first damping rods. A damping block is provided inside the ring frame. A limit block is fixedly connected to the other end of each of the two first damping rods. A first spring is sleeved on the outer wall of each of the two first damping rods. One end of the first spring is fixedly connected to the first damper, and the other end of the first spring is fixedly connected to the ring frame.

[0011] When encountering crosswinds, the hopper will sway back and forth. When the hopper tilts, the damping block will slide to the other side under the action of gravity, thereby offsetting the stress and keeping the swaying hopper stable.

[0012] Preferably, two second damping rods are symmetrically fixedly connected to the outer wall of the hopper, and a second damper is slidably connected to the outer wall of each of the two second damping rods. A connecting shaft is rotatably connected to the outer wall of each of the two second dampers, and a counterweight is rotatably connected to one end of each of the two connecting shafts. A second spring is sleeved on the outer wall of the second damping rod, and one end of the second spring is fixedly connected to the hopper, while the other end of the second spring is fixedly connected to the second damper.

[0013] By using counterweights, the hopper is tilted towards the side closer to the building facade, thus bringing gravity closer to the facade and reducing the impact of wind. When the hopper swings left and right, a second damper, in conjunction with a second spring, dampens the counterweights that collide with the facade, preventing hard collisions that could damage the facade.

[0014] Preferably, a plurality of third rotating shafts are fixedly connected at equal intervals to the outer wall of the counterweight, and pulleys are rotatably connected to the outer wall of the third rotating shafts;

[0015] By using pulleys that fit against the exterior of the building, the friction between the counterweight and the exterior is reduced, allowing the hopper to be lifted smoothly.

[0016] Preferably, the bottom of the hopper is equipped with casters;

[0017] The casters make it easy to move the hopper on the ground and load materials.

[0018] Preferably, a control panel is provided on the top of the support platform, and the control panel is electrically connected to both the motor and the electric telescopic rod;

[0019] The control panel allows you to start and stop the motor and the electric telescopic pole.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. The irregular cement cover plate hoisting and lifting device of this utility model supports the bottom of the pull rope with guide wheels. When the external wind force is strong, the fixed frame is moved towards the outer facade of the building by the electric telescopic rod. Guided by the guide wheels, the hopper moves closer to the outer facade of the building, thereby reducing the impact of wind on the hopper. When encountering crosswinds, the hopper will swing back and forth. When the hopper tilts, the damping block will slide to the other side under the action of gravity, thereby offsetting the stress and keeping the swaying hopper stable. Through the cooperation of the pull rope and the reinforcing rope, the hopper can be better close to the outer facade of the building.

[0022] 2. The irregular cement cover plate hoisting and lifting device of this utility model uses a counterweight to tilt the hopper towards the side closer to the building facade, thereby making the gravity close to the building facade, facilitating the movement of the hopper close to the building facade, reducing the impact of wind, and using a second damper in conjunction with a second spring to dampen the counterweight when it hits the building facade, avoiding hard collisions between the counterweight and the building facade and causing damage to the building facade.

[0023] 3. The irregular cement cover plate hoisting and lifting device of this utility model uses pulleys to fit against the exterior wall of the floor, reducing the friction between the counterweight and the exterior wall, so that the hopper can be hoisted smoothly. Attached Figure Description

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] like Figures 1 to 6As shown, this utility model provides a technical solution: an irregular cement cover plate hoisting and lifting device, including a support platform 1. Two side plates 11 are symmetrically fixedly connected to the top of the support platform 1. A motor 12 is fixedly connected to the outer wall of one of the side plates 11. The output end of the motor 12 passes through the side plate 11 and is fixedly connected to a first rotating shaft 13. Two winding rollers 14 are symmetrically fixedly connected to the outer wall of the first rotating shaft 13. Pull ropes 15 are wound around the outer walls of both winding rollers 14. One end of each pull rope 15 is fixedly connected to a hopper 16. The top of the hopper 16 is away from the pull ropes. A reinforcing rope 17 is fixedly connected to one side of the hopper 15, and one end of the reinforcing rope 17 is fixedly connected to the pull rope 15. An anti-vibration component is provided at the bottom of the hopper 16. An electric telescopic rod 2 is fixedly connected to one side of each of the two side plates 11. A fixed frame 21 is fixedly connected to the output end of each of the two electric telescopic rods 2. A second rotating shaft 22 is fixedly connected between the two fixed frames 21. A guide wheel 23 is rotatably connected to the outer wall of the second rotating shaft 22. A limit shaft 24 is fixedly connected to the outer wall of the fixed frame 21. The limit shaft 24 is slidably connected to the side plate 11. Casters 18 are provided at the bottom of the hopper 16.

[0041] With the above technical solution, the support platform 1 is set up on the roof. The motor 12 is started, which drives the first rotating shaft 13 to rotate clockwise, causing the two winding rollers 14 to rotate clockwise, which facilitates the release of the pull rope 15 and moves the hopper 16 downward, making it easier to put the cement board on the ground into the hopper 16. The casters 18 are set to facilitate the movement of the hopper 16 on the ground for easy loading. Then, the motor 12 controls the winding rollers 14 to rotate counterclockwise, winding the pull rope 15. As the pull rope 15 is pulled, the hopper 16 can move upward to lift the cement board. The bottom of the pull rope 15 is supported by the guide wheel 23. When the outside wind is strong, the electric telescopic rod 2 controls the fixed frame 21 to move towards the exterior of the building. Guided by the guide wheel 23, the hopper 16 is brought closer to the exterior of the building, thereby reducing the impact of the wind on the hopper 16. Through the cooperation of the pull rope 15 and the reinforcing rope 17, the hopper can be better close to the exterior of the building.

[0042] Specifically, the seismic-resistant component includes a mounting frame 3. Two first dampers 31 are symmetrically fixedly connected to the inner wall of the mounting frame 3. A first damping rod 32 is slidably connected inside each of the two first dampers 31. A ring frame 34 is fixedly connected between the two first damping rods 32. A damping block 35 is provided inside the ring frame 34. A limit block 33 is fixedly connected to the other end of each of the two first damping rods 32. A first spring 36 is sleeved on the outer wall of each of the two first damping rods 32. One end of the first spring 36 is fixedly connected to the first damper 31, and the other end of the first spring 36 is fixedly connected to the ring frame 34.

[0043] With the above technical solution, when encountering crosswinds, the hopper 16 will sway back and forth. When the hopper 16 tilts, the damping block 35 will slide to the other side under the action of gravity, thereby offsetting the stress and keeping the swaying hopper 16 stable.

[0044] Specifically, two second damping rods 4 are symmetrically fixedly connected to the outer wall of the hopper 16. The outer walls of the two second damping rods 4 are slidably connected to second dampers 42. The outer walls of the two second dampers 42 are rotatably connected to connecting shafts 43. One end of the two connecting shafts 43 is rotatably connected to a counterweight 44. A second spring 41 is sleeved on the outer wall of the second damping rod 4. One end of the second spring 41 is fixedly connected to the hopper 16, and the other end of the second spring 41 is fixedly connected to the second damper 42. Several third rotating shafts 45 are equidistantly fixedly connected to the outer wall of the counterweight 44. The outer walls of the third rotating shafts 45 are rotatably connected to pulleys 46.

[0045] Through the above technical solution, the counterweight 44 is set to tilt the hopper 16 towards the side closer to the building facade, thereby making the gravity close to the building facade and reducing the impact of wind. When the hopper 16 swings left and right, the second damper 42 and the second spring 41 are set to dampen the counterweight 44 that hits the building facade, avoiding a hard collision between the counterweight 44 and the building facade and causing damage to the building facade. When the hopper 16 is hoisted upward, the pulley 46 is set to fit against the building facade, reducing the friction between the counterweight 44 and the building facade, so that the hopper 16 can be hoisted smoothly.

[0046] Specifically, a control panel 19 is provided on the top of the support platform 1, and the control panel 19 is electrically connected to the motor 12 and the electric telescopic rod 2.

[0047] Through the above technical solution, the start and stop of the motor 12 and the electric telescopic rod 2 can be controlled through the control panel 19.

[0048] In use, the support platform 1 is set up on the roof. The motor 12 is started, driving the first rotating shaft 13 to rotate clockwise, causing the two winding rollers 14 to rotate clockwise, facilitating the release of the pull rope 15 and moving the hopper 16 downwards. This allows cement slabs from the ground to be placed into the hopper 16. Casters 18 facilitate the movement of the hopper 16 on the ground for easy loading. Then, the motor 12 controls the winding rollers 14 to rotate counterclockwise, winding the pull rope 15. As the pull rope 15 is pulled, the hopper 16 can move upwards to hoist the cement slabs. Guide wheels 23 support the bottom of the pull rope 15. When the wind is strong, the electric telescopic rod 2 controls the fixed frame 21 to move towards the exterior facade of the building. Guided by the guide wheels 23, the hopper 16 moves closer to the exterior facade, reducing the impact of wind on the hopper 16. The pull rope 15 and reinforcing rope... The combination of 17 allows the hopper to better fit against the building facade. When encountering crosswinds, the hopper 16 will sway back and forth. When the hopper 16 tilts, the damping block 35 will slide to the other side under the action of gravity, thereby offsetting the stress and keeping the swaying hopper 16 stable. The counterweight 44 makes the hopper 16 tilt towards the side closer to the building facade, thereby making the gravity closer to the building facade and reducing the impact of wind. When the hopper 16 sways left and right, the second damper 42 and the second spring 41 dampen the counterweight 44 that impacts the building facade, preventing the counterweight 44 from having a hard collision with the building facade and causing damage to the building facade. When the hopper 16 is hoisted upward, the pulley 46 fits against the building facade, reducing the friction between the counterweight 44 and the building facade, allowing the hopper 16 to be hoisted smoothly.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
