Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of belt conveyors, and particularly relates to a limit stop structure for a belt conveyor. Background Art
[0002] A belt conveyor (also known as a belt-type conveyor) is a general mechanical equipment that uses a continuously moving conveyor belt as the core carrier to achieve long-distance and high-efficiency continuous conveying of bulk materials or packaged goods. Its core principle is that the driving device (motor, reducer, etc.) drives the conveyor belt to circulate, and uses the friction or clamping force between the conveyor belt and the material to smoothly convey the material from the starting point to the end point. It is widely used in many fields such as mines, metallurgy, chemical industry, food, ports, logistics, etc., and is one of the core equipment in the "material handling" link of modern production and logistics systems.
[0003] Specifically, during the process of a belt conveyor transporting materials, affected by the superposition of multiple factors, it is extremely easy for materials to shift and fall: if the conveyor belt runs off track, or the material loading point is offset during material loading, or the material humidity / particle size fluctuates, it will cause the material to deviate from the center of the conveyor belt and fall from the side or joint. This will not only cause material loss, but also trigger a chain of problems: the fallen materials accumulate under the frame and idlers, which is easy to jam the idlers or drive drums, resulting in increased wear of the conveyor belt, and even causing the conveyor belt to tear and the motor to overload and stop; if the transported material is a chemical corrosive material, the fallen material will also corrode the equipment foundation and pollute the surrounding environment, increasing safety hazards and cleaning and maintenance costs, and seriously affecting the continuous operation efficiency of the conveying system. Content of the Utility Model
[0004] The purpose of the utility model is to provide a limit stop structure for a belt conveyor, aiming to solve the problem that during the process of a belt conveyor transporting materials, affected by the superposition of multiple factors, it is extremely easy for materials to shift and fall: if the conveyor belt runs off track, or the material loading point is offset during material loading, or the material humidity / particle size fluctuates, it will cause the material to deviate from the center of the conveyor belt and fall from the side or joint. This will not only cause material loss, but also trigger a chain of problems: the fallen materials accumulate under the frame and idlers, which is easy to jam the idlers or drive drums, resulting in increased wear of the conveyor belt.
[0005] To achieve the above object, the utility model provides the following technical solution: a limit stop structure for a belt conveyor, including a bracket and a mounting support plate installed on one side of the bracket.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention involves installing a mounting plate on one side of the bracket onto the side of the belt conveyor frame. Rotating the turntable then drives the bidirectional lead screw to rotate, simultaneously adjusting the first and second threaded cylinders.

[0016] 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.
[0017] Please refer to Figures 1-4. The present invention provides the following technical solution: a limit block structure for a belt conveyor, including a bracket 1 and a mounting plate 2 installed on one side of the bracket 1. A sliding sleeve 3 is sleeved on the surface of the bracket 1. A crossbeam plate 4 is connected to one side of the sliding sleeve 3. A sliding block 5 is connected to the inner wall of the opening of the crossbeam plate 4. A limit block 6 is connected to one side of the sliding block 5. The other side of the limiting block 6 is connected to the first threaded cylinder 7. The surface of the first threaded cylinder 7 is connected to the bidirectional lead screw 8. One end of the bidirectional lead screw 8 is connected to the turntable 9. The bottom surface of the sliding block 5 is connected to the stop mounting bracket 10. The stop block 11 is installed at the recess of the stop mounting bracket 10. The surface of the bidirectional lead screw 8 is connected to the second threaded cylinder 12.
[0018] Preferably, the sliding block 5 and the opening in the inner wall of the crossbeam plate 4 form a sliding connection structure, and the first threaded cylinder 7 and the second threaded cylinder 12 are both threadedly connected to the bidirectional lead screw 8.
[0019] Preferably, the bottom surface of the second threaded cylinder 12 is provided with a stop mounting bracket 10 and a limiting stop 11. In actual use, by rotating the bidirectional lead screw 8, the first threaded cylinder 7 and the second threaded cylinder 12 can be moved synchronously, thereby facilitating the quick adjustment of the limiting stop 11.
[0020] Preferably, the crossbeam plate 4 is connected to the support 1 via a sliding sleeve 3, and an adjusting block 13 is movably connected to one side of the sliding sleeve 3. In actual use, by sliding the sliding sleeve 3 on the surface of the support 1, the height of the limiting block 11 can be easily adjusted to adapt to different conveying environments.
[0021] Preferably, the other end of the adjusting block 13 is connected to a linkage plate 14, one side of the linkage plate 14 is connected to a locking spring 15, and the other end of the locking spring 15 is connected to the inner wall of the sliding sleeve 3. The locking spring 15 and the linkage plate 14 form an elastic telescopic structure. In actual use, the elastic telescopic structure between the locking spring 15 and the linkage plate 14 facilitates the movement and adjustment of the locking insert 16.
[0022] Preferably, a locking block 16 is connected to the side of the linkage plate 14 opposite to the locking spring 15, and a socket 17 is provided on the side of the bracket 1 near the locking block 16. The locking block 16 and the socket 17 on one side of the bracket 1 form a fitting structure. In actual use, by fitting the locking block 16 into the socket 17 on the surface of the bracket 1, the crossbeam plate 4 can be quickly and stably installed.
[0023] The working principle of this utility model in specific use is as follows: First, the mounting plate 2 on one side of the bracket 1 is installed with bolts. On the side of the belt conveyor frame, the turntable 9 is rotated, driving the bidirectional lead screw 8 to rotate, simultaneously driving the first threaded cylinder 7 and the second threaded cylinder 12 to adjust synchronously. This then drives the sliding block 5 to adjust its position along the crossbeam plate 4, while the limiting block 6 slides along one side opening of the crossbeam plate 4. This causes the stop mounting bracket 10 on the bottom surface of the sliding block 5 to move, thereby limiting the conveyed material through the limiting stop 11, preventing material deviation and falling, and improving the material conveying efficiency. Additionally, by pulling the adjusting block 13 on one side of the sliding sleeve 3, the linkage plate 14 is driven to compress the locking spring 15, simultaneously causing the locking insert 16 to move synchronously. When the sliding sleeve 3 slides to a suitable position on the surface of the bracket 1, the adjusting block 13 is released. Due to the rebound force of the locking spring 15, the locking insert 16 is driven to engage with the insertion hole 17 on the surface of the bracket 1, facilitating the locking and fixing of the sliding sleeve 3, and thus facilitating the adjustment of the limiting stop 11. The height can be adjusted to suit different conveying conditions.
[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
