Description
Technical Field
[0001] The utility model relates to a device for preventing materials from being scattered due to excessive height of a belt conveyor, and belongs to the technical field of belt conveyor equipment. Background Art
[0002] Belt conveyors are usually composed of rollers, rollers, belts, drive devices, feeding devices, loading and unloading hoppers, etc., and are widely used in ports, mining, power plants, steel mills and other industries. In the actual operation process, even if the quality of the materials fed by the belt conveyor feeder is the same, the materials and densities of the transported materials are different, and the sizes and shapes of the materials are also different, which will cause the heights of the materials on the belt conveyor to be different. Due to the different height densities, irregular materials will be too high during the transportation process. When the excessively high materials enter the belt conveyor loading and unloading hopper, the material height is too high and exceeds the upper edge of the hopper, which will cause the material to spill. This results in a reduction in the quality of the materials actually transported, affecting the quality of freight. Therefore, it is very necessary to develop a device for detecting the height of the materials transported by the belt conveyor to avoid spilling of materials due to excessive height, which affects the quality of freight.

DETAILED DESCRIPTION
[0017] The utility model is composed of a telescopic bracket 1, a limiting base 2, a bracket base 3, a limiting bracket 4, a mechanical ram horn limiting 5, a detection wire rope 6, and a clamping plate 14.
[0018] Figure 1It is shown that the telescopic bracket 1 is a foldable telescopic guardrail structure, and the folding and telescopic direction of the foldable telescopic guardrail structure is in the vertical direction. The telescopic bracket 1 is composed of multiple steel strips 7, fixing bolts 8 and nuts. The multiple steel strips 7 have the same length. Each steel strip 7 has a connection hole in the center and at both ends. Two steel strips 7 are placed overlappingly. The central connection holes of the two steel strips 7 are fixedly connected by fixing bolts 8 and nuts to form a cross steel plate. The connection holes at both ends of the steel strips 7 of the multiple cross steel plates are connected in sequence by fixing bolts 8 and nuts to form a foldable and telescopic bracket. The height of the telescopic bracket 1 can be changed by stretching the telescopic bracket 1 to both ends or compressing it to the middle. This structure is the same as the general foldable telescopic guardrail structure, but the device is placed vertically and is used to adjust the height of the limit structure.
[0019] Figure 1 It is shown that the upper ends of the two telescopic brackets 1 are respectively connected to the two limit bases 2, and the lower ends of the two telescopic brackets 1 are respectively connected to the two bracket bases 3. The limit base 2 is used to install the limit bracket 4 and the mechanical ram limit 5, and the bracket base 3 is used to be fixedly connected to the belt conveyor.
[0020] Figure 1 As shown, the limit base 2 and the bracket base 3 are respectively composed of a bottom plate 9 and a sliding groove plate 10. The bottom plate 9 and the sliding groove plate 10 are rectangular plates respectively. The sliding groove plate 10 is vertically welded to the surface of the bottom plate 9, and there is a sliding groove 11 along the length direction in the middle of the sliding groove plate 10. The connection holes at both ends of the steel strips 7 at both ends of the telescopic bracket 1 are respectively opposite to the sliding groove 11 of the sliding groove plate 10, and the fixing bolts 8 pass through the connection holes at both ends of the steel strips 7 and the sliding groove 11 of the sliding groove plate 10 and are fixedly connected by nuts. By adjusting the position of the two ends of the steel strips 7 in the sliding groove 11, the telescopic bracket 1 can be stretched to both ends or compressed to the middle, and the height of the telescopic bracket 1 can be changed. Due to the characteristics of the folding telescopic guardrail structure, each steel strip 7 of the telescopic bracket 1 will always maintain the same angle during the telescopic process, so the width of the steel strips 7 at both ends of the telescopic bracket 1 in the limit base 2 and the bracket base 3 is always consistent.
[0021] Figure 1 It is shown that the upper part of the two limit bases 2 is respectively fixed with the limit bracket 4. The limit bracket 4 is composed of two bracket plates 12 and a rib plate 13. The two bracket plates 12 are placed in parallel. The distance between the two bracket plates 12 matches the thickness of the mechanical ram limit 5. The lower ends of the two bracket plates 12 are welded to the upper plane of the limit base 2. The plate surfaces of the two bracket plates 12 have an inclination angle with the upper plane of the limit base 1, and the inclination angle is toward the incoming direction of the belt conveyor. The mechanical ram limit 5 is inserted into the two bracket plates 12 of the limit bracket 4. The front of the two bracket plates 12 has rib plates 13 respectively welded to the upper plane of the limit base 2.
[0022] Figure 1 , 3 It shows that the contact of the mechanical horn limit 5 is facing the incoming direction of the belt, and the two contacts of the mechanical horn limit 5 are respectively connected to the two ends of the detection wire rope 6, and the detection wire rope 6 is straightened.
[0023] Figure 2 It is shown that the card plate 14 is composed of two L-shaped plates, and the front parts of the long plates of the two L-shaped plates are respectively provided with long slot holes 15. The long plates of the two L-shaped plates are overlapped and placed, and the long slot holes 15 on the long plates are opposite to each other. The width of the long slot holes 15 matches the diameter of the adjustment bolt 16. The adjustment bolt 16 passes through the long slot holes 16 of the two L-shaped plates and is locked and connected by nuts. The distance between the inner sides of the two short plates of the two L-shaped plates of the card plate 14 matches the distance between the steel strips 7 on both sides of the telescopic bracket 1. The inner sides of the two short plates of the two L-shaped plates of the card plate 14 are clamped on the outside of the steel strips 7 on both sides of the telescopic bracket 1. By pulling out the two L-shaped plates to both sides and closing them to the middle, the width of both sides of the card plate 14 can be adjusted. When in use, the card plate 14 is clamped on the outside of the steel strips 7 of the telescopic bracket 1 to offset the lateral force on the fixing bolts 8 and prevent loosening.
[0024] Figure 3 It is shown that the use process of the utility model is as follows:
[0025] Weld the bottom plates 9 of the two bracket bases 3 to the belt conveyor support channel steels 17 on both sides of the belt conveyor, and then connect the lower end steel plate strip 7 of the telescopic bracket 1 to the sliding groove 11 of the sliding groove plate 10 of the bracket base 3 through the fixing bolts 8. The fixing bolts 8 do not need to be tightened first;
[0026] Connect the upper steel strip 7 of the telescopic bracket 1 to the sliding groove 11 of the sliding groove plate 10 of the limiting base 2 through the fixing bolts 8, and do not tighten the fixing bolts 8 first;

[0029] Adjust the width of the clamping plate 14 and clamp the clamping plate 14 on the outside of the steel strip 7 of the telescopic bracket 1 to offset the lateral force on the fixing bolt 8 and prevent it from loosening;
