Description

Technical Field

[0001] This utility model relates to a synchronous detection device for the track of a bucket chain conveyor, belonging to the field of four-track detection technology for bucket chain conveyors. Background Technology

[0002] A chain bucket conveyor is a conveying device that uses plate chains to carry buckets that run on tracks. It is suitable for conveying dry granular materials with a particle size of about 20mm, with a maximum particle size not exceeding 100mm. The temperature of the conveyed material should preferably be below 100℃, and the maximum temperature should not exceed 200℃. It is commonly used in power plants, mines, and coal mines for conveying materials such as boiler ash, cement clinker, iron slag, mineral slag, limestone, coke, and crushed stone, especially for conveying materials with high temperature, high density, large size, sharp edges, and high abrasiveness. Furthermore, chain bucket conveyors have a wide range of applications due to their advantages such as large conveying capacity, long service life, low maintenance, low operating costs, and ability to handle steep inclines. The application of chain bucket conveyors will select horizontal or inclined conveying methods depending on the space available. Inclined conveying adds a turning section, increasing the stacking height of materials. During this lifting process, attention needs to be paid to the passability of the guide rails in the turning section. To facilitate the lifting and conveying of materials, guide rails will be modified according to the lifting height. These guide rails are divided into upper and lower guide rails, which facilitates the passability of the chain sprockets, prevents material spillage, and reduces wear between the chain and the guide rails.

[0003] In existing technologies, custom-made gap steel bars are generally used. These bars can only measure the gap on one side of the guide rail, which is cumbersome to operate manually. More importantly, the specific deviation of the gap between the upper and lower guide rails cannot be reliably measured, and the gap steel bar cannot pass through smoothly when the gap is too small.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This invention addresses the shortcomings of the prior art by providing a synchronous detection device for the track of a chain bucket conveyor. It can automatically detect changes in the gap between the upper and lower guide rails without manual inspection and can accurately detect the change in the gap value.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: A chain bucket conveyor track synchronization detection device includes a conveyor frame, on which an upper guide rail and a lower guide rail are arranged opposite to each other along its length. The upper guide rail and the lower guide rail are provided with a certain slope. A detection trolley is provided between the upper guide rail and the lower guide rail. The two sides of the detection trolley are provided with parallel side rods, and each side rod has a lower detection wheel rotatably installed at both ends. Each side rod has a rocker arm hinged symmetrically at both ends. The lower end of the rocker arm is hinged to the side rod, and the upper end of the rocker arm is rotatably mounted with an upper detection wheel. A telescopic rod connects the two rocker arms.

[0007] Furthermore, an axle is connected between the two lower detection wheels located at the same end of the side rod.

[0008] Furthermore, the rocker arm extends outward beyond the end of the side rod, so that the upper detection wheel is located outside the lower detection wheel.

[0009] Furthermore, a transverse connecting rod connects the two rocker arms on the same side, and the telescopic rod includes a middle telescopic rod located in the middle position and end telescopic rods inserted at both ends of the middle telescopic rod.

[0010] Furthermore, the outer end of the end telescopic rod is hinged to the transverse connecting rod, and the inner end of the end telescopic rod is connected to the intermediate telescopic rod through a tension spring.

[0011] Furthermore, each end of the side rod is symmetrically provided with an arc-shaped track, the rocker arm is provided with a protruding shaft, the protruding shaft cooperates with the arc-shaped track, and a detection camera is installed on the arc-shaped track.

[0012] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: The upper detection wheel swings up and down with the rocker arm, and the detection camera detects the amount of up and down swing of the upper detection wheel by detecting the position change of the protruding shaft on the rocker arm. This allows for the detection of the gap between the upper and lower guide rails, and the detection of the amount of movement of the upper detection wheel can be accurately detected. Therefore, manual inspection is not required, and the change in the gap between the upper and lower guide rails is automatically processed.

[0013] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0016] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0017] like Figure 1-3 As shown, this utility model provides a chain bucket conveyor track synchronization detection device, including a conveyor frame 1, on which an upper guide rail 101 and a lower guide rail 102 are arranged opposite to each other along its length direction, and the upper guide rail 101 and the lower guide rail 102 are provided with a certain slope. A detection trolley is provided between the upper guide rail 101 and the lower guide rail 102. The detection trolley has parallel side rods 2 on both sides, and each side rod 2 has a lower detection wheel 3 rotatably mounted at both ends. Each side rod 2 has a rocker arm 5 symmetrically hinged at both ends. The lower end of the rocker arm 5 is hinged to the side rod 2, and the upper end of the rocker arm 5 is rotatably mounted with an upper detection wheel 6. A telescopic rod is connected between the two rocker arms 5.

[0018] An axle 4 is connected between the two lower detection wheels 3 located at the same end of the side rod 2.

[0019] The rocker arm 5 extends outward beyond the end of the side rod 2, so that the upper detection wheel 6 is located outside the lower detection wheel 3.

[0020] A transverse connecting rod 13 connects the two rocker arms 5 on the same side. The telescopic rod includes a middle telescopic rod 7 located in the middle position and end telescopic rods 8 inserted at both ends of the middle telescopic rod 7. The outer end of the end telescopic rod 8 is hinged to the transverse connecting rod 13, and the inner end of the end telescopic rod 8 is connected to the middle telescopic rod 7 through a tension spring 9. The two telescopic rods apply a certain pulling force to the rocker arms 5 on both sides, causing the two rocker arms 5 to generate an upward swinging force, so that the upper measuring wheel 6 can press against the upper guide rail 102 and roll along the upper guide rail 102, thereby detecting the gap between the upper guide rail 101 and the lower guide rail 102.

[0021] The two ends of the side rod 2 are respectively provided with an arc-shaped track 10 symmetrically. The rocker arm 5 is provided with a protruding shaft 11, which cooperates with the arc-shaped track 10. The arc-shaped track 10 is equipped with a detection camera 12.

[0022] The specific working principle of this utility model: The lower detection wheels 3 on the two side rods 2 of the inspection trolley roll along the lower guide rails 102 on both sides of the conveyor frame 1, and the upper detection wheels 6 on the upper ends of the rocker arms 5 on both sides roll along the upper guide rails 101 on both sides of the conveyor frame 1. The two telescopic rods apply a certain pulling force to the rocker arms 5 on both sides, causing the two rocker arms 5 to generate an upward swinging force, so that the upper detection wheels 6 can press against the upper guide rails 102. When the inspection trolley is placed between the upper guide rails 101 and the lower guide rails 102, the telescopic rods on both sides are pressed down to move the upper detection wheels 6 down, so that the inspection trolley can be smoothly placed between the upper guide rails 101 and the lower guide rails 102.

[0023] During the detection process, the lower detection wheel 3 and the upper detection wheel 6 roll in contact with the upper guide rail 101 and the lower guide rail 102, respectively. When the gap changes, the upper detection wheel 6 swings up and down with the rocker arm 5. The detection camera 12 detects the amount of up and down swing of the upper detection wheel 6 by detecting the position change of the protruding shaft 11 on the rocker arm 5, thereby realizing the detection of the gap between the upper guide rail 101 and the lower guide rail 102. Moreover, it can accurately detect the amount of movement of the upper detection wheel 6, so that no manual detection is required and the change of the gap between the upper guide rail 101 and the lower guide rail 102 is automatically detected.
