Description
Technical Field
[0001] The invention relates to the field of hoisting equipment, in particular to a balancing device used for hoisting materials by a tower crane. Background Art
[0002] The most widely used vertical transportation and hoisting equipment in construction projects is tower crane, commonly known as tower crane. The main advantages of the equipment are beautiful appearance, stability and reliability, light weight of the crane arm, adjustable length, fast lifting speed, easy operation, low failure rate, simple maintenance, etc. It is mostly used in high-rise civil buildings, bridges and water conservancy projects, large-span industrial plants and other projects. This equipment is mainly composed of foundation, tower body, crane arm, motor, counterweight and hook and other components. During the hoisting construction, a steel wire rope is installed on the tower crane hook, and a lifting ring is installed at the lower end of the steel wire rope to fix the material for hoisting. However, there are also certain disadvantages during the hoisting construction, such as: 1. Mainly during the hoisting construction, the construction workers fix the material when the center of gravity of the two ends of the material is unstable, causing side sliding and falling to injure people; 2. During the hoisting construction, the two steel wire ropes fixed on the tower crane hook are entangled with each other, and the high-speed rotation caused by the wind in the air causes the material to be unstable and fall and injure people; 3. When the tower crane hook is lowered for hoisting construction, the two steel wire ropes are entangled with each other, affecting the time of fixing the material and reducing the efficiency, making the hoisting process very unsafe. For this reason, we designed a balancing device for tower crane hoisting materials. Summary of the invention

The insides of the two horizontal tubes are slidably connected with toothed plates. A driving mechanism is installed in the middle of the limit plate, and the opposite ends of the two toothed plates are engaged with the output ends of the driving mechanism.
[0007] The separated ends of the two tooth plates are fixedly connected with a movable plate which is slidably connected to the front side of the limit plate, and the separated ends of the two movable plates are fixedly connected with a fixing ring.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0021] See also Figure 1-3 A balancing device for tower crane hoisting materials includes a hoisting device 1, a limit plate 2 is suspended at the bottom of the hoisting device 1, and a connecting hole 3 connected to the hoisting mechanism 1 is opened on the top of the limit plate 2. The hoisting can be carried out by the hoisting device 1 connected to the hoisting machinery, and then the limit plate 2 can be driven to move in conjunction with the connecting hole 3.
[0022] Horizontal tubes 4 are installed on the left and right sides of the front of the limit plate 2, and the horizontal tube 4 on the left is lower than the horizontal tube 4 on the right. The interiors of the two horizontal tubes 4 are slidably connected with tooth plates 5. A driving mechanism 6 is installed in the middle of the limit plate 2. The opposite ends of the two tooth plates 5 are engaged with the output ends of the driving mechanism 6. After the driving mechanism 6 is started, the tooth plates 5 can be driven to move. The tooth plates 5 on both sides will move in different directions. The horizontal tubes 4 can limit the tooth plates 5 to prevent the tooth plates 5 from tilting.
[0023] The separated ends of the two toothed plates 5 are fixedly connected with a moving plate 7 which is slidably connected to the front side of the limiting plate 2, and the separated ends of the two moving plates 7 are fixedly connected with a fixing ring 8. Positioning holes 9 are provided on the left and right sides of the bottom of the limiting plate 2, and a steel cable 10 is fixedly connected to the bottom of the positioning hole 9, and a positioning ring 11 is fixedly connected to the bottom of the steel cable 10. Ear plates 12 are installed on the left and right side walls of the limiting plate 2, and a fastening spring 13 is fixedly connected to the bottom of the ear plate 12, and the bottom of the fastening spring 13 is fixedly connected to the top of the moving plate 7. When the toothed plate 5 moves, the moving plate 7 will be driven to move synchronously, and when the moving plate 7 moves, the fixing ring 8 will be driven to move, and the spacing between the two fixing rings 8 can be adjusted. In this way, during the lifting process, the steel wire used for lifting can be passed through the two fixing rings 8, so that during the lifting process, the material will not slide sideways and fall and injure people due to the instability of the two ends, and it can also be based on The lifting wires can be fixed on the corresponding positioning ring 11 in this way, so that the spacing between the fixed wires at both ends of the fixed object can be increased. During the lifting process, the wires will not slip, and the fixed objects will not slide sideways due to the unstable center of gravity at both ends. At the same time, the distance between the wires at both ends is increased, so that the wires will not be entangled and knotted in the air, making the entire lifting process safer and ensuring the efficiency of lifting.
[0024] The lifting device 1 is connected to a tower crane or a lifting machine, and can then lift and transfer large equipment and construction materials. The lifting device 1 includes a fixing part 14 connected to the lifting machine, and a hook 15 is fixedly connected to the bottom of the fixing part 14. The hook 15 passes through the connecting hole 3 and is connected to the limit plate 2. The hook 15 at the bottom of the fixing part 14 can hang the limit plate 2.
[0025] The driving mechanism 6 can drive the two tooth plates 5 to move in opposite directions. The driving mechanism 6 includes a driving motor 16 installed in the middle of the back side of the limit plate 2. The output shaft of the driving motor 16 is fixedly connected to a driving gear 17 meshing with the two tooth plates 5. After the driving motor 16 is powered on and started, it can drive the driving gear 17 to rotate. When the driving gear 17 rotates, it can drive the two tooth plates 5 meshing therewith to move in opposite directions, thereby adjusting the distance between the two movable plates 7 and the fixed ring 8.
[0026] When the tooth plate 5 moves, it will drive the moving plate 7 to move synchronously. The left and right sides of the front face of the limit plate 2 are provided with sliding grooves 18 corresponding to the moving plate 7. The moving plate 7 is located inside the sliding groove 18. The front and rear side walls of the sliding groove 18 are provided with transverse grooves 19. The interior of the transverse groove 19 is slidably connected with a guide plate 20 fixedly connected to the moving plate 7. When the moving plate 7 moves, it will drive the guide plate 20 to slide in the transverse groove 19, which can not only keep the moving plate 7 moving smoothly, but also enhance the strength of the moving plate 7, thereby avoiding the fixed ring 8 and the moving plate 7 from deflecting and bending when hoisting heavier objects, thereby ensuring the hoisting effect and safety.
[0027] In summary, when the present invention is in use, the object to be hoisted is fixed by the hoisting steel wire, and then the two ends of the steel wire can be respectively fixed on the two fixed rings 8, and then the two tooth plates 5 are controlled to move in opposite directions by the driving mechanism 6. In this way, the distance between the two movable plates 7 and the fixed ring 8 can be adjusted, and the hoisting steel wire can also be fixed on the corresponding positioning ring 11. In this way, the distance between the fixed steel wires at both ends of the fixed object can be increased. During the hoisting process, the steel wire will not slip, and the fixed object will not slide sideways due to the unstable center of gravity at both ends. At the same time, the distance between the steel wires at both ends is increased, so that the steel wires will not be entangled and knotted in the air, making the entire hoisting process safer and ensuring the high efficiency of the hoisting.
