Description

Technical Field

[0001] This utility model belongs to the technical field of coal mine conveying equipment, specifically relating to a speed roller support device applied to a coal mine conveyor belt. Background Technology

[0002] The speed sensor roller in a mine is suspended from the upper surface of the coal mine conveyor belt via a bracket and rotates in contact with the belt due to friction. During belt transport, the belt contains many impurities, both metallic and non-metallic, and the belt surface is covered with coal dust and slag. Near the coal bunker, it is frequently affected by coal dust and metal foreign objects. The sensor probe can be covered by mud or obstructed by foreign objects, affecting the speed sensor's signal detection and causing problems with its lifespan and maintenance. Furthermore, the speed sensor, mounted on the belt surface, poses a risk of falling and being carried away by the belt. If it falls due to loose adjusting rings or fixing screws, the roller will move at high speed with the belt, and the uncontrolled flying roller could easily cause injury, creating a safety hazard. Utility Model Content

[0003] To address the technical problems of existing technologies, such as the long-term use of mining speed sensors in harsh environments, and the impact of mud, water, or foreign objects on the sensor probe affecting speed sensor signal detection, this utility model provides a side-mounted speed roller support device that can be installed on a belt support. The side-mounted support can automatically remove foreign objects from the speed sensor roller, while also enhancing the effective friction between the roller and the belt, improving the accuracy of speed detection, and reducing the risk of the roller falling off and flying off, causing injury.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a speed roller support device that can be installed on the side of a belt conveyor, including a main support, a first lateral support fixedly provided on one side of the main support, the first lateral support having multiple through holes, and bolts passing through the through holes on the first lateral support and connecting to the belt conveyor; a second lateral support fixedly provided on the other side of the main support, the second lateral support having multiple through holes, and bolts passing through the through holes on the second lateral support and connecting to the belt conveyor; and multiple lower fixed supports arranged at intervals on the top of the main support.

[0005] The lower fixed support includes a main base. A first sliding groove is provided on one side of the main base in the vertical direction, and a second sliding groove is provided on the other side of the main base in the vertical direction. The slide rail on one side of the upper movable support is slidably connected in the first sliding groove corresponding to the main base, and the slide rail on the other side of the upper movable support is slidably connected in the second sliding groove corresponding to the main base. The upper movable support can slide up and down relative to the lower fixed support, thereby adjusting the distance between the upper movable support and the lower fixed support.

[0006] The upper movable support and the lower fixed support bracket are supported by four springs. The top nut of the guide rod is locked on the upper movable support. The guide rod passes through the upper movable support, the corresponding spring, and the lower fixed support in sequence and is locked by a nut. The spring is fitted on the corresponding guide rod. Under the action of the spring force, when the upper movable support is subjected to downward pressure, the upper movable support is elastically pressed down.

[0007] The top of the upper movable support is equipped with two ear plates, and a central shaft is installed horizontally between the two ear plates. A speed measuring roller is mounted on the central shaft.

[0008] Preferably, the number of lower fixed supports is three.

[0009] The main support includes a symmetrically arranged front panel and a rear panel, both of which have a V-shaped structure. The V-shaped structure ensures that the speed measuring roller fits tightly against the bottom of the belt. One side of the front panel and the rear panel is movably connected to the first lateral support by multiple bolts, and the other side of the front panel and the rear panel is movably connected to the second lateral support by multiple bolts. The size of the first lateral support and the second lateral support can be adjusted according to the lateral width of the belt support. The first lateral support and the second lateral support are detachable and replaceable to accommodate speed measurement of belts of various sizes.

[0010] A limit stop is provided at the top of the slide rail on one side of the upper movable support, and a limit stop is provided at the top of the slide rail on the other side of the upper movable support. The limit stop can limit the extreme sinking position of the upper movable support.

[0011] Compared with the prior art, the specific advantages of this utility model are as follows: This utility model, through the side-mounted speed roller support device, can effectively solve the technical problems of foreign objects stuck in the speed sensor and inaccurate detection due to belt vibration. By side-mounting the speed measuring device, the roller can always maintain close contact with the bottom surface of the belt. In addition, during the belt conveying process, dirt and other debris on the sensing probe will fall off during the overall vibration, achieving self-cleaning without the need for additional cleaning equipment. The entire device is simple and efficient, which can improve the accuracy of belt speed detection and ensure safe production. Attached Figure Description

Detailed Implementation

[0017] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] like Figure 1-4 As shown, a speed roller support device that can be mounted on the side of a belt support includes a main support 1. The main support 1 includes a symmetrically arranged front panel 11 and a rear panel 12. Both the front panel 11 and the rear panel 12 are V-shaped structures. The bottoms of the front panel 11 and the rear panel 12 are connected by a base plate. One side of the front panel 11 and the rear panel 12 is movably connected to a first lateral support 2 by multiple bolts. The first lateral support 2 has multiple through holes. The other side of the front panel 11 and the rear panel 12 is movably connected to a second lateral support 3 by multiple bolts. The second lateral support 3 has multiple through holes. The size of the first lateral support 2 and the second lateral support 3 can be adjusted according to the lateral width of the belt support. The first lateral support 2 and the second lateral support 3 are detachable and replaceable to adapt to speed measurement of belts of various sizes.

[0019] Three lower fixed supports 4 are arranged on the base plate of the main support 1. The three lower fixed supports 4 are arranged at intervals. The lower fixed supports 4 on both sides are arranged at an angle, and the lower fixed supports 4 in the middle are arranged vertically.

[0020] The lower fixed support 4 includes a main base 41. A first sliding groove 42 is provided on one side of the main base 41 in the vertical direction, and a second sliding groove 43 is provided on the other side of the main base 41 in the vertical direction. The first sliding groove 42 and the second sliding groove 43 are arranged symmetrically. The slide rail 51 on one side of the upper movable support 5 is slidably connected in the first sliding groove 42 corresponding to the main base 41, and the slide rail 51 on the other side of the upper movable support 5 is slidably connected in the second sliding groove 43 corresponding to the main base 41. The upper movable support 5 can slide up and down relative to the lower fixed support 4, thereby adjusting the distance between the upper movable support 5 and the lower fixed support 4.

[0021] The bottom of the upper movable support 5 is provided with four circular grooves, and the top of the lower fixed support 4 is provided with four corresponding circular grooves. Springs 52 are press-fitted between the corresponding circular grooves on the upper movable support 5 and the lower fixed support 4. The top of the guide rod 53 is provided with a nut. The bottom of the guide rod 53 passes through the upper movable support 5, the corresponding springs 52, and the lower fixed support in sequence and is locked by a nut. The springs 52 are fitted on the corresponding guide rods 53. When the upper movable support 5 is pressed down, the upper movable support 5 and the lower fixed support 4 are elastically connected under the action of the elastic force of the four springs 52.

[0022] The top of the upper movable support 5 is provided with two ear plates, which are symmetrically arranged. A central shaft 54 ​​is installed horizontally between the two ear plates. A speed measuring roller 55 is installed in the middle of the central shaft 54, and the speed measuring roller 55 can rotate around the central shaft 54.

[0023] Among them, the top of the slide rails 51 on both sides of the upper movable support 5 are provided with limit locking heads 56, which can limit the extreme sinking position of the upper movable support 5.

[0024] During equipment installation, the entire speed measuring device is installed on one side of the belt support (and near the end of the conveyor belt). The bolt passes through the corresponding through hole on the first lateral support 2 and is connected to the belt support. The bolt passes through the corresponding through hole on the second lateral support 3 and is connected to the belt support. Under the action of the spring 52, the three speed measuring rollers 55 elastically press against the bottom surface of the running belt. During the transmission process, the running belt drives the three speed measuring rollers 55 to rotate. The rotation of the three speed measuring rollers 55 realizes belt speed measurement and ensures speed measurement accuracy. By employing a side-mounted speed measuring device positioned on the underside of the running belt, debris such as mud that falls or splashes onto the speed measuring roller 55 during belt operation will not directly fall onto the speed measuring roller 55. This effectively solves the technical problems of foreign objects getting stuck on the speed roller and inaccurate detection due to belt vibration, ensuring accurate detection. In addition, the speed measuring roller 55 is elastically pressed onto the underside of the running belt. As the belt moves up and down, even if a small amount of coal mud or ash adheres to the underside of the belt, the speed measuring roller 55 will detach during vibration, achieving self-cleaning. No additional cleaning equipment is required. The entire device is simple and efficient, improving speed detection accuracy and ensuring safe production.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall be included within the scope of the present utility model.
