Description

Technical Field

[0001] This utility model relates to the field of winch technology, and in particular to a self-balancing double-cable winch for stage hoists. Background Technology

[0002] A winch is a small, lightweight lifting device that uses a drum to wind wire rope or chain to lift or pull heavy objects; it is also called a winch. Winches can lift vertically and pull horizontally or at an angle. There are three types of winches: manual winches, electric winches, and hydraulic winches. Electric winches are the most common. They can be used independently or as components in lifting, road construction, and mine hoisting machinery. They are widely used due to their simple operation, large rope capacity, and ease of relocation.

[0003] A novel blast furnace body charging double-lifting system hoist with authorized publication number CN216235814U is disclosed. The hoist includes a furnace body. A first clamping hoop and a second clamping hoop are fixedly connected to the top and bottom of the outer wall of the furnace body, respectively. A first mounting base and a second mounting base are fixedly connected to one side of the first clamping hoop and the other side of the second clamping hoop, respectively. Two hoist bodies are arranged at the top end of the second mounting base. An installation opening is opened in the middle of the first mounting base, and a U-shaped hanger is fixedly connected between the top two sides of the installation opening. Hanging rods are fixedly connected to both ends of the top inner wall of the U-shaped hanger, and hanging rings are fixedly connected to the bottom of each hanging rod. This invention provides the entire furnace body with a double-lifting charging structure, resulting in better feeding performance. The guide seat and guide frame, along with the support wheels and cables, effectively maintain the charging frame in a balanced and stable state, preventing the charging frame from tipping over.

[0004] Regarding the aforementioned technologies, the existing winches have the following drawbacks: when the double rods lift materials by means of traction ropes, if the materials are too heavy, deformation, tilting, or even instability may occur due to unilateral overload. Therefore, this utility model provides a self-balancing double-cable winch for stage hoists. Utility Model Content

[0005] The purpose of this application is to provide a self-balancing double-cable winch for stage hoists, in order to solve the problem mentioned in the background art that when materials are lifted and lowered by traction ropes on two poles, deformation, tilting or even instability may occur due to unilateral overload when the materials are too heavy.

[0006] To achieve the above objectives, this application provides the following technical solution: a self-balancing double-cable winch for stage hoists, comprising a base plate, with a pair of balance adjustment components disposed on the outer side of the base plate; the balance adjustment components include a bearing seat disposed above the base plate, a bearing rod passing through the bearing seat, an angle sensor disposed on the outer side of the bearing rod, a threaded rod rotatably connected to one end of the bearing rod, a toothed ring fixedly connected to the outer side of the threaded rod, a motor fixedly connected to the outer side of the bearing rod, a gear fixedly connected to the output end of the motor, the gear meshing with the toothed ring, a sliding block threadedly connected to the outer side of the threaded rod, and a counterweight fixedly connected to the outer side of the sliding block.

[0007] Preferably, a guide rod is fixedly connected to the outer side of the bearing rod, and the guide rod passes through the sliding block.

[0008] Preferably, a fixing block is fixedly connected to the end of the guide rod away from the bearing rod, and the end of the threaded rod away from the bearing rod is rotatably connected to the fixing block.

[0009] Preferably, a pair of support plates are fixedly connected to the outer side of the base plate, and a motor is fixedly connected to the outer side of the support plates.

[0010] Preferably, the output end of the motor passes through the support plate, and a take-up roller is fixedly connected to the output end of the motor.

[0011] Preferably, a pair of positioning plates are fixedly connected to the outer side of the base plate, and the end of the take-up roller away from the motor is rotatably connected to the positioning plates.

[0012] Preferably, two pairs of load-bearing frames are fixedly connected to the outer side of the base plate, the bearing seat is disposed between the two load-bearing frames located on the same side, and a winding hole is provided at the end of the bearing rod away from the threaded rod.

[0013] In summary, the technical effects and advantages of this utility model are as follows: In this invention, by setting up a balance adjustment component, the position of the counterweight can be adjusted in real time. The gravitational torque generated by the counterweight can offset part of the overturning torque during hoisting, reduce the lateral displacement of the bearing rod, and indirectly reduce the horizontal force that the lateral stabilizer needs to bear. In addition, the two ends of the winding hole are set with arc surfaces, which reduces friction on the traction rope and increases the service life of the traction rope. Attached Figure Description

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Example 1: Reference Figure 1-4The invention describes a self-balancing double-cable winch for stage hoists. This application includes a controller and a power supply. The controller controls electrical components (such as a motor and telescopic hydraulic cylinder), and the power supply provides power. It also includes an oil supply mechanism for the hydraulic cylinder, which is prior art and will not be described further. The winch includes a base plate 1 that supports the overall structure and provides an installation reference. A pair of balance adjustment components are installed on the outer side of the base plate 1 to monitor and adjust the equipment's balance in real time. The balance adjustment components include a bearing seat 7 located above the base plate 1 to fix the bearing rod and reduce its rotational friction. A bearing rod 6, supporting various components and enabling rotational transmission, is installed through the bearing seat 7. An angle sensor 8 is installed on the outer side of the bearing rod 6 to detect the bearing rod's tilt angle and provide balance information. One end of the bearing rod 6 is rotatably connected to a threaded rod 10 that moves a sliding block by rotation. A toothed ring 15, transmitting motor power to the threaded rod, is fixedly connected to the outer side of the threaded rod 10. An electric motor 13 providing driving force is fixedly connected to the outer side of the ring gear 15. A gear 14 that transmits the motor torque to the ring gear is fixedly connected to the output end of the electric motor 13. The gear 14 meshes with the ring gear 15. A sliding block 9 that moves along the threaded rod 10 to adjust the position of the counterweight is threadedly connected to the outer side of the threaded rod 10. A counterweight 12 that adjusts the center of gravity of the equipment to achieve balance by changing its position is fixedly connected to the outer side of the sliding block 9. A guide rod 18 passes through the sliding block 9. A fixing block 11 that fixes the guide rod and the end of the threaded rod and enhances the structural stability is fixedly connected to the end of the guide rod 18 away from the bearing rod 6. The end of the threaded rod 10 away from the bearing rod 6 is rotatably connected to the fixing block 11.

[0019] Example 2: Reference Figure 1-4 Based on the same concept as in Embodiment 1 above, this embodiment also proposes that a pair of support plates 2 are fixedly connected to the outer side of the base plate 1. The support plates 2 are used to stably support the motor 3 and ensure the stability of the motor 3 during operation. The motor 3 provides power for the rotation of the take-up roller 4. The output end of the motor 3 passes through the support plates 2. The output end of the motor 3 is fixedly connected to the take-up roller 4, which is used to wind up or release the traction rope. A pair of positioning plates 17 are fixedly connected to the outer side of the base plate 1. The positioning plates 17 provide positioning and support for the end of the take-up roller 4 away from the motor 3. The end of the take-up roller 4 away from the motor 3 is rotatably connected to the positioning plates 17. Two pairs of load-bearing frames 5 are fixedly connected to the outer side of the base plate 1. The load-bearing frames 5 are used to support and fix the bearing seats 7. The bearing seats 7 are located between the two load-bearing frames 5 on the same side. The bearing rod 6 has a winding hole 16 at the end away from the threaded rod 10. The two ends of the winding hole 16 are arc-shaped. The winding hole 16 is used for the traction rope to pass through and be fixed to prevent the traction rope from falling off.

[0020] The working principle of this utility model is as follows: The traction rope is led out from the take-up roller 4 and passes through the winding hole 16 to lift the material. The motor 3 drives the take-up roller 4 to rotate, thereby lifting and lowering the material. During the lifting and lowering process, the bearing rod 6 may shift. The tilt angle is monitored by the tilt angle sensor 8. The motor 13 drives the gear 14 to rotate, which drives the threaded rod 10 to rotate through the gear ring 15. The sliding block 9 drives the counterweight block 12 to move. The gravitational torque generated by the counterweight can offset part of the overturning torque during hoisting, reduce the lateral displacement of the bearing rod 6, and indirectly reduce the horizontal force that the lateral stabilizer bar needs to bear.
