Description

Technical Field

[0001] This utility model relates to the field of hoists, specifically a balancing device for a hoist. Background Technology

[0002] A balancing device for a hoist is used to counteract fluctuations in the hoisting load and ensure smooth operation. The device typically uses a suspended counterweight or a hydraulic balancing cylinder, connected to the hoisting container by a wire rope, utilizing gravity or hydraulic pressure to create a counter-pull. Some models incorporate an automatic compensation system that adjusts the balancing amount according to load changes, and guide wheels ensure vertical movement of the counterweight. Suitable for hoists in mines, construction sites, etc., it reduces motor load, lowers wire rope wear, and improves system safety and operational efficiency.

[0003] In existing technical solutions, relying on simple counterweights or hydraulic balance cylinders makes it difficult to respond accurately to complex load changes in real time. When the weight of the lifted goods fluctuates, imbalance is likely to occur, causing the hoist to shake violently and making it difficult to accurately transport the goods to the installation position. In order to solve this technical problem, this utility model proposes a balancing device for the hoist. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In existing technical solutions, relying on simple counterweights or hydraulic balance cylinders makes it difficult to respond accurately to complex load changes in real time. When the weight of the lifted goods fluctuates, imbalance is likely to occur, causing the hoist to shake violently and making it difficult to accurately transport the goods to the installation position. In order to solve this technical problem, this utility model proposes a balancing device for the hoist.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a balancing device for a hoist, comprising a base, a mounting seat fixedly connected to the top of the base, a motor fixedly mounted on the top of the mounting seat, a rotating shaft fixedly connected to the output end of the motor, a winding roller fixedly connected to the outer wall of the rotating shaft, and a connecting belt wound around the outside of the winding roller, a connecting plate fixedly connected to the other end of the connecting belt, a material box provided below the connecting plate, and a pair of damping rods provided between the material box and the connecting plate, with multiple sets of springs provided on the outer wall of the damping rods.

[0008] Preferably, a pair of limiting seats are fixedly connected to the bottom of the connecting plate, and the two ends of the damping rod are rotatably connected to the limiting seats and the material box respectively through the limiting rod, and the two ends of the spring are fixedly connected to the damping rod and the limiting rod respectively.

[0009] Preferably, a pair of mounting plates are fixedly connected to both sides of the material box, and a pair of rotating columns are rotatably connected between the two mounting plates. Each rotating column has a pulley fixedly connected to its outer side wall.

[0010] Preferably, a bracket is fixedly connected to the top of the base, and a pair of sliding rods are fixedly connected to the outer wall of the bracket, with the pulley slidably connected to the outer wall of the sliding rods.

[0011] Preferably, a U-shaped seat is fixedly connected to the top of the bracket, a rotating rod is rotatably connected inside the U-shaped seat, and a roller is fixedly connected to the outer wall of the rotating rod, while a connecting belt is slidably connected to the outer wall of the roller.

[0012] Preferably, a counterweight is fixedly connected to the top of the base, a pair of fixed plates are fixedly connected to the top of the base, and a rotating shaft is rotatably connected inside the fixed plates. A pair of mounting brackets are fixedly connected to both side walls of the base, an electric push rod is fixedly connected inside the mounting bracket, and two pairs of universal wheels are fixedly connected to the bottom of the base.

[0013] (III) Beneficial Effects

[0014] This utility model provides a balancing device for a hoist. It has the following beneficial effects:

[0015] (1) After the motor starts, the drive shaft drives the winding roller to rotate. The winding connecting belt pulls the material box to lift and lower. The connecting plate is connected to the limit seat. When the material box shakes, the offset force is buffered by the elastic damping effect of the damping rod and the spring. This structure solves the problem of large shaking and poor stability of traditional lifting equipment. Traditional equipment lacks effective buffering, which causes the goods to shake during transportation and is easily damaged by collision. This device greatly reduces the amplitude of shaking through linkage buffering, while extending the service life of the equipment and significantly improving logistics efficiency and safety.

[0016] (2) The loading box is fixedly connected to the mounting plate. The pulley on the rotating column inside the mounting plate is engaged with the sliding rod. When the loading box is raised or lowered, the pulley rolls along the sliding rod. Due to the low coefficient of rolling friction, the friction force when the loading box moves is greatly reduced. At the same time, the sliding rod forms a limiting guide for the pulley, so that the loading box can only move smoothly along the direction of the sliding rod, avoiding back and forth shaking. This design solves the problems of large shaking and high friction loss when the loading box moves in the existing device. Traditional equipment has large sliding friction resistance, which causes the loading box to run stuck, increases energy consumption, and is prone to tipping over due to shaking. The operation stability is significantly improved, effectively ensuring the safety of cargo transportation, extending the service life of the equipment, and improving the overall work efficiency.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1-3 This utility model provides a technical solution:

[0023] Example 1: A balancing device for a hoist includes a base 1, a mounting base 2 fixedly connected to the top of the base 1, a motor 3 fixedly mounted on the top of the mounting base 2, a rotating shaft 4 fixedly connected to the output end of the motor 3, a pair of fixed plates 5 fixedly connected to the top of the base 1, and the rotating shaft 4 rotatably connected within the fixed plates 5. A winding roller 6 is fixedly connected to the outer wall of the rotating shaft 4, and a connecting belt 7 is wound around the outside of the winding roller 6. A connecting plate 12 is fixedly connected to the other end of the connecting belt 7. A material box 16 is provided below the connecting plate 12, and the material box 16 is connected to the connecting plate 12. A pair of damping rods 14 are provided, and multiple sets of springs 15 are provided on the outer wall of the damping rods 14. A pair of limiting seats 13 are fixedly connected to the bottom of the connecting plate 12. The two ends of the damping rods 14 are rotatably connected to the limiting seats 13 and the material box 16 through the limiting rods 17 respectively. The two ends of the springs 15 are fixedly connected to the damping rods 14 and the limiting rods 17 respectively. A U-shaped seat 9 is fixedly connected to the top of the bracket 8. A rotating rod 10 is rotatably connected inside the U-shaped seat 9. A roller 11 is fixedly connected to the outer wall of the rotating rod 10. At the same time, the connecting belt 7 is slidably connected to the outer wall of the roller 11.

[0024] After the goods are placed in the loading box 16, the motor 3 on the top mounting seat 2 of the base 1 is started. The motor 3 drives the rotating shaft 4, which in turn rotates the winding roller 6 to wind up the connecting belt 7. As the connecting belt 7 is wound up, its other end pulls the loading box 16 and the goods to rise smoothly. During this process, the rollers 11 inside the U-shaped seat 9 provide guidance for the connecting belt 7, effectively reducing friction and wear. If the loading box 16 tilts left or right during transportation, the damping rod 14 and spring 15 on one side will be stretched. The elastic buffering force and damping force generated by the two work together to quickly counteract the shaking caused by the tilt, ensuring that the loading box 16 remains stable during the ascent, and achieving safe and smooth transportation of the goods.

[0025] Example 2: The difference between this example and Example 1 is that, in this example, a pair of mounting plates 18 are fixedly connected to both sides of the material box 16, and a pair of rotating columns 19 are rotatably connected between the two mounting plates 18. A pulley 20 is fixedly connected to the outer wall of each rotating column 19. A bracket 8 is fixedly connected to the top of the base 1, and a pair of sliding rods 21 are fixedly connected to the outer wall of the bracket 8. The pulley 20 is slidably connected to the outer wall of the sliding rod 21. A counterweight 22 is fixedly connected to the top of the base 1. A pair of mounting frames 23 are fixedly connected to both sides of the base 1. An electric push rod 24 is fixedly connected inside the mounting frame 23. Two pairs of universal wheels 25 are fixedly connected to the bottom of the base 1.

[0026] When the loading box 16 rises, the pulley 20 on the rotating column 19 inside the mounting plate 18 slides along the sliding rod 21. The pulley 20 significantly reduces the movement resistance due to its rolling friction characteristics. At the same time, its cooperation with the sliding rod 21 provides precise guidance for the loading box 16, effectively suppressing back and forth swaying and ensuring smooth transportation of goods. The casters 25 at the bottom of the equipment facilitate flexible movement. After reaching the designated position, the electric push rod 24 on the mounting frame 23 is activated. The push rod extends and lifts the equipment, causing the casters 25 to leave the ground and achieve stable support, ensuring the stability and safety of the equipment during operation.

[0027] Working principle: First, the worker places the goods into the loading box 16. Then, the motor 3 on the top mounting base 2 of the base 1 is started, driving the winding roller 6 on the rotating shaft 4 to rotate and winding the connecting belt 7. The other end of the connecting belt 7 lifts the loading box 16 and the goods. The connecting belt 7 is guided by rollers 11 inside the U-shaped seat 9 to reduce friction. If the goods tilt left or right during transport within the loading box 16, it will pull the damping rod 14 and spring 15 on the other side. At this time, the elastic force of the damping rod 14 and the spring... The damping force of the spring 15 will buffer the movement, thereby preventing swaying during the ascent and ensuring stable transportation. When the material box 16 rises, the pulley 20 on the rotating column 19 inside the mounting plate 18 moves to the upper limit of the slide bar 21. The pulley 20 can effectively reduce the friction generated during movement and play a guiding role, preventing the material box 16 from swaying back and forth during movement, thus improving the working equipment. The equipment is moved by the casters 25 and is lifted by the electric push rod 24 on the mounting frame 23, so that the equipment is fixedly supported.
