Abstract

This utility model discloses a hoist chain tensioning component, relating to the field of chain tensioning technology. A support plate is fixedly connected to the top surface of the thickened plate, and a first motor is fixedly connected to one side of the support plate. A first bidirectional threaded rod is fixedly connected to the output end of the first motor. Two first movable plates are threaded onto the first bidirectional threaded rod. In this utility model, when the hoist chain needs tension adjustment, the first motor is started to drive the first bidirectional threaded rod to rotate. Since the first bidirectional threaded rod has two sections of threads in opposite directions, the two first movable plates will move closer or further apart under the action of the first bidirectional threaded rod, thereby driving the fixed plate, rotating rod, and first sprocket to move simultaneously. Then, the two first sprockets adjust the second chain outwards, achieving initial adjustment of the second chain tension, ensuring the stability and durability of the tensioning effect, and facilitating long-term operation.

Description

Technical Field

[0001] This utility model relates to the field of chain tensioning technology, specifically to a chain tensioning component for a hoist. Background Technology

[0002] The chain tensioning component of a hoist system is a critical part of the hoist system. Its main function is to ensure that the chain maintains appropriate tension during operation, preventing chain slack, skipped teeth, or detachment, thereby ensuring the stable operation and efficient work of the hoist. In the industrial production field, as an important material transportation device, the stability and reliability of the hoist's operation directly affect production efficiency and safety. Due to the long-term load on the hoist chain and continuous friction with components such as sprockets, wear and stretching will gradually occur. These factors will lead to an increase in chain length and subsequent slack. When the chain is slack, the meshing state with the sprocket will be severely affected, easily leading to slippage, skipped teeth, and other problems. This not only reduces the hoist's lifting capacity but also poses a great threat to operational stability, and may even cause equipment failure, affecting the normal operation of the entire production process, increasing the risk of component damage, further affecting the overall performance and reliability of the hoist, reducing work efficiency, and diminishing its practicality.

[0003] Therefore, there is an urgent need for a chain tensioning component for elevators to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a hoist chain tensioning component to solve the problem mentioned in the background art that the hoist chain will gradually wear and stretch due to long-term load bearing and continuous friction with components such as sprockets.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hoist chain tensioning component, comprising a thickened plate, a support plate fixedly connected to the top surface of the thickened plate, a first motor fixedly connected to one side of the support plate, a first bidirectional threaded rod fixedly connected to the output end of the first motor, two first movable plates threadedly connected to the first bidirectional threaded rod, two fixed plates fixedly connected to one side of the two first movable plates, a rotating rod rotatably connected to both fixed plates, and a first sprocket fixedly connected to the outer wall of the two rotating rods.

[0006] Preferably, a first fixing rod is rotatably connected to one side of the support plate, the first fixing rod passes through two first moving plates, and the two first moving plates are provided with first threaded holes.

[0007] Preferably, the top surface of the thickened plate is fixedly connected to two connecting plates, and the two connecting plates are provided with a second bidirectional threaded rod. The outer wall of the second bidirectional threaded rod is rotatably connected to the two connecting plates. The second bidirectional threaded rod is threadedly connected to two second movable plates. The top surface of the second movable plate is fixedly connected to a second motor, and the output end of the second motor is fixedly connected to the second bidirectional threaded rod.

[0008] Preferably, an adapter plate is fixedly connected to one side of each of the two second movable plates, and a first chain is fixedly connected to one side of each of the two adapter plates.

[0009] Preferably, the two connecting plates are provided with a second fixing rod, the outer wall of the second fixing rod is rotatably connected to the two connecting plates, the two connecting plates are provided with a second threaded hole, and the two second moving plates are provided with a round hole.

[0010] Preferably, a second chain is provided on the thickened plate, and a second sprocket is provided on the second chain, with the second sprocket meshing with the second chain.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] Under the action of the components, when the tension of the hoist chain needs to be adjusted, the first motor is started to drive the first bidirectional threaded rod to rotate. Since there are two sections of threads with opposite directions on the first bidirectional threaded rod, the two first moving plates will move closer or further apart under the action of the first bidirectional threaded rod, thereby driving the fixed plate, rotating rod and first sprocket to move simultaneously. Then the two first sprockets will adjust the second chain outward, realizing the initial adjustment of the tension of the second chain, ensuring the stability and durability of the tension effect, which is conducive to long-term work. By starting the second motor to drive the second bidirectional threaded rod to rotate, the two second moving plates move on the second bidirectional threaded rod, thereby affecting the state of the second chain and the second sprocket, realizing further precise adjustment of the chain tension.

[0019] 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.

[0020] Example 1

[0021] Please see Figures 1-5 The diagram shows a chain tensioning component for a hoist, including a thickened plate 1. A support plate 9 is fixedly connected to the top surface of the thickened plate 1. A first motor 2 is fixedly connected to one side of the support plate 9. A first bidirectional threaded rod 3 is fixedly connected to the output end of the first motor 2. Two first movable plates 5 are threadedly connected to the first bidirectional threaded rod 3. Two fixed plates 6 are fixedly connected to one side of the two first movable plates 5. Rotating rods 7 are rotatably connected to the two fixed plates 6. First sprockets 8 are fixedly connected to the outer walls of the two rotating rods 7.

[0022] A first fixed rod 4 is rotatably connected to one side of the support plate 9. The first fixed rod 4 passes through two first movable plates 5, and the two first movable plates 5 are provided with first threaded holes.

[0023] When it is necessary to adjust the tension of the hoist chain, the first motor 2 is started to drive the first bidirectional threaded rod 3 to rotate. Since there are two threads in opposite directions on the first bidirectional threaded rod 3, the two first moving plates 5 will move closer or further away from each other under the action of the first bidirectional threaded rod 3, thereby driving the fixed plate 6, the rotating rod 7 and the first sprocket 8 to move simultaneously. Then the two first sprockets 8 will adjust the second chain 18 outward.

[0024] This allows for the initial adjustment of the tension of the second chain (18), ensuring the stability and durability of the tension effect, facilitating long-term operation, providing convenience and speed, saving time, enhancing flexibility, and expanding the scope of application.

[0025] Please see Figure 5The thickened plate 1 in the figure has two connecting plates 10 fixedly connected to its top surface. The two connecting plates 10 are provided with a second bidirectional threaded rod 11. The outer wall of the second bidirectional threaded rod 11 is rotatably connected to the two connecting plates 10. The second bidirectional threaded rod 11 is threadedly connected to two second moving plates 12. The top surface of the second moving plate 12 is fixedly connected to a second motor 13. The output end of the second motor 13 is fixedly connected to the second bidirectional threaded rod 11.

[0026] A transition plate 15 is fixedly connected to one side of each of the two second movable plates 12. A first chain 16 is fixedly connected to one side of each of the two transition plates 15. A second fixing rod 14 is provided on each of the two connecting plates 10. The outer wall of the second fixing rod 14 is rotatably connected to the two connecting plates 10. A second threaded hole is provided on each of the two connecting plates 10. A round hole is provided on each of the two second movable plates 12. A second chain 18 is provided on the thickened plate 1. A second sprocket 17 is provided on the second chain 18. The second sprocket 17 and the second chain 18 mesh with each other.

[0027] By starting the second motor 13, the second bidirectional threaded rod 11 is driven to rotate, causing the two second moving plates 12 to move on the second bidirectional threaded rod 11. Then, the two second moving plates 12 move horizontally under the action of the second fixed rod 14. Then, the second moving plates 12 drive the adapter plate 15 to move outward. Through the adapter plate 15, the first chain 16 moves, which in turn affects the state of the second chain 18 and the second sprocket 17, so as to achieve further precise adjustment of the chain tension.

[0028] Through the coordinated action of the first motor 2 and the second motor 13, the tension can be precisely adjusted according to the actual slack of the chain, realizing the automated adjustment of the tensioning components. This eliminates the need for frequent manual operation, improving the efficiency and convenience of tension adjustment. Furthermore, the precise control of the motors, based on the wear condition of the chain and different working conditions, enhances practicality and work efficiency.

[0029] Working principle:

[0030] When the tension of the hoist chain needs to be adjusted, the first motor 2 is started to drive the first bidirectional threaded rod 3 to rotate. Since there are two sections of threads with opposite directions on the first bidirectional threaded rod 3, the two first moving plates 5 will move closer or further apart under the action of the first bidirectional threaded rod 3, thereby driving the fixed plate 6, the rotating rod 7 and the first sprocket 8 to move simultaneously. Then the two first sprockets 8 adjust their positions outward to achieve the initial adjustment of the chain tension, ensuring the stability and durability of the tension effect, which is conducive to long-term work, convenient and quick, saves time, enhances flexibility and expands the scope of application.

[0031] By starting the second motor 13, the second bidirectional threaded rod 11 is driven to rotate, causing the two second moving plates 12 to move on the second bidirectional threaded rod 11. Then, the two second moving plates 12 move horizontally under the action of the second fixed rod 14. Then, the second moving plates 12 drive the adapter plate 15 to move outward. Through the adapter plate 15, the first chain 16 moves, which in turn affects the state of the second chain 18 and the second sprocket 17, so as to achieve further precise adjustment of the chain tension.

[0032] Through the coordinated action of the first motor 2 and the second motor 13, the tension can be dynamically and precisely adjusted according to the actual slack of the chain, solving the problems of insufficient dynamic compensation capability and difficulty in achieving tension accuracy in the existing technology. This realizes the automated adjustment of the tensioning components, eliminating the need for frequent manual operation and improving the efficiency and convenience of tension adjustment. It can also be precisely controlled by the motor according to the wear condition of the chain and different working conditions.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
