Technical Field

[0001] This utility model relates to the field of telescopic belt conveyor technology, specifically to an adjustable height belt head support device. Background Technology

[0002] Telescopic belt conveyors are adjustable-length conveying equipment widely used in logistics, warehousing, ports, and other industries. They are especially suitable for situations where the conveying distance needs to be adjusted according to actual requirements. Their main feature is that the length of the belt can be changed through a telescopic device, usually achieved through mechanical, pneumatic, or hydraulic systems. They are simple and convenient to operate. Telescopic belt conveyors can be quickly deployed in different environments, and the length of the conveyor belt can be flexibly adjusted according to the type of material and handling requirements. This not only improves work efficiency but also reduces the labor intensity of manual handling.

[0003] When using existing telescopic belt conveyors, the length of the belt needs to be adjusted according to the transmission distance. If there is no support device at the head of the belt after adjustment, the belt head may become unstable when the belt is extended, affecting the transmission efficiency. Therefore, an adjustable height belt head support device is needed to meet people's needs. Utility Model Content

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.

[0024] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: an adjustable height belt cable head support device, comprising a device body 1; an adjustment mechanism 2 is provided at one end of the device body 1, the adjustment mechanism 2 includes two lifting columns 21 installed inside the device body 1, the lifting columns 21 having threaded grooves 22, two threaded rods 23 rotatably installed inside the device body 1, a first rotating sleeve 24 installed on the side of the threaded rods 23, a drive motor 25 installed at one end of the device body 1, a second rotating sleeve 26 installed at one end of the drive motor 25, and one threaded rod 23. A third rotating sleeve 27 is installed at one end of the device. A first connecting band 28 is installed on the side of the second rotating sleeve 26 and the third rotating sleeve 27. A second connecting band 29 is installed on the side of the first rotating sleeve 24. The two first rotating sleeves 24 are connected by the second connecting band 29. An installation sleeve 3 is installed at one end of the lifting column 21. A rotating rod 4 is rotatably installed at one end of the installation sleeve 3. A connecting rod 5 is installed on the side of the rotating rod 4. A bearing plate 6 is installed on the top of the connecting rod 5. A limit bolt 7 is installed at one end of the installation sleeve 3. A fixing plate is installed at one end of the device body 1. 12. The fixing plate 12 is adapted to the second connecting belt 29. A motor housing 15 is installed on the side of the main body 1 of the device. The motor housing 15 is adapted to the drive motor 25. When it is necessary to support the head of the belt conveyor, the main body 1 of the device is placed at the bottom of the belt conveyor. The drive motor 25 is started to drive the second rotating sleeve 26 to rotate. The first connecting belt 28 on the side of the second rotating sleeve 26 drives the third rotating sleeve 27 to rotate, thereby adjusting the threaded rod 23 to rotate. When the threaded rod 23 rotates, it drives the first rotating sleeve 24 to rotate, which in turn drives the second connecting belt 29 to rotate. The transmission drives another first rotating sleeve 24 to rotate, causing the two threaded rods 23 to rotate simultaneously. The threads of the threaded rods 23 drive the lifting column 21 to slide within the main body 1 of the device, allowing the lifting column 21 to rise or fall. This adjusts the height of the main body 1 so that the bearing plate 6 at the top of the lifting column 21 abuts against the bottom of the belt conveyor. As the height of the main body 1 continues to rise, the connecting rod 5 rotates, causing one end of the bearing plate 6 to abut against the belt conveyor. After the height is adjusted, the position of the rotating rod 4 is fixed by rotating the limiting bolt 7, preventing the connecting rod 5 from rotating.

[0025] Example 2: Figure 2 and 4As shown, a base 8 is installed at one end of the main body 1 of the device. Multiple circular grooves 9 are opened at the bottom of the main body 1. Multiple guide posts 10 are installed in the base 8. Springs 11 are sleeved on the side of the guide posts 10. Multiple indicator lights 13 are installed on the side of the main body 1. An indicator 14 is installed at one end of the main body 1. The circular grooves 9 are adapted to the guide posts 10. One end of the spring 11 is installed on the inner wall of the base 8, and the other end of the spring 11 is installed on the main body 1 of the device. When the belt conveyor is working, it will generate a certain vibration. At this time, the bottom of the main body 1 of the device slides in the base 8 and squeezes the spring 11. The circular grooves 9 slide under the limit of the guide posts 10. Through the elastic force of multiple springs 11, the main body 1 of the device will generate a certain buffer when squeezed, which will offset the vibration generated by the belt conveyor during operation and make the belt transmission more stable. The indicator lights 13 and indicator 14 on the side of the main body 1 of the device will provide audible and visual prompts when the belt conveyor is running, which will help the operator to better use the belt conveyor and improve the applicability of the device. The remaining features are the same as in Embodiment 1.

[0026] The working principle is as follows: When support is needed for the head of the conveyor belt, the main body 1 of the device is placed at the bottom of the conveyor belt. The drive motor 25 is started to drive the second rotating sleeve 26 to rotate. The first connecting belt 28 on the side of the second rotating sleeve 26 drives the third rotating sleeve 27 to rotate, which in turn drives the threaded rod 23 to rotate. When the threaded rod 23 rotates, it drives the first rotating sleeve 24 to rotate. Through the transmission of the second connecting belt 29, it drives the other first rotating sleeve 24 to rotate, so that the two threaded rods 23 rotate simultaneously. The threads of the threaded rods 23 drive the lifting column 21 to slide inside the main body 1 of the device, so that the lifting column 21 can rise or fall. The height of the main body 1 is adjusted so that the bearing plate 6 at the top of the lifting column 21 abuts against the bottom of the conveyor belt. When the height of the main body 1 is adjusted, the lifting column 21 can move up or down. As the height continues to rise, the connecting rod 5 rotates, causing one end of the bearing plate 6 to abut against the belt conveyor. After the height is adjusted, the position of the rotating rod 4 is fixed by rotating the limit bolt 7, preventing the connecting rod 5 from rotating. When the belt conveyor is working, it will generate a certain vibration. At this time, the bottom of the device body 1 slides in the base 8 and squeezes the spring 11. The circular groove 9 slides under the limit of the guide post 10. Through the elastic force of multiple springs 11, the device body 1 generates a certain buffer when squeezed, which offsets the vibration generated when the belt conveyor is running, making the belt transmission more stable. The indicator light 13 and indicator 14 on the side of the device body 1 provide audible and visual prompts when the belt conveyor is running, assisting the operator in better using the belt conveyor and improving the applicability of the device.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
