Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of scraper conveyors, in particular, relates to a device and method for adjusting the posture of a middle trough of a scraper conveyor. BACKGROUND

[0002] As the core transport equipment of the coal underground mining working face, the scraper conveyor has a structure in which the middle trough accounts for as high as 80% of the proportion, becoming the key part and main component of the equipment, and the reliability thereof has a direct impact on the working efficiency of the scraper conveyor.

[0003] In the inclined and steeply inclined mining environment where the coal seam inclination is more than thirty degrees, the equipment stability can be damaged due to the large inclination of the working face, and more importantly, when the coal seam inclination is greater than the natural repose angle of the gangue, the gangue tends to slide downward, further exacerbating the instability of the equipment. At present, the maximum applicable inclination of the scraper conveyor in China is still limited to less than 30° of the coal seam. Once the coal seam inclination exceeds this range, the scraper conveying equipment will face a series of severe challenges, including the unbalanced sliding of the conveyed material and the huge impact load of the material on the equipment, which can easily lead to the failure of the equipment parts, and thus the mining technology development level of the large-inclination coal seam lags far behind that of the gently inclined coal seam.

[0038] EMBODIMENT

[0039] As Figures 1-7The adjusting device for the middle trough posture of a scraper conveyor shown in the figure comprises the following parts: a middle trough 1 arranged on a working surface as a channel for material conveying. The middle trough 1 comprises a plurality of trough bodies 11 connected in sequence; the bottom of the trough body 11 is provided with a wedge-shaped adjusting plate 3 for changing the inclination angle of the middle trough 1; a hydraulic support 2 is arranged at the bottom of the middle trough 1 and between two adjacent trough bodies 11 to support the trough body and thus realize posture adjustment. A telescopic component 4 is integrated in the base 21 of the hydraulic support 2, one end of the telescopic component 4 is connected with the hydraulic support 2, and the other end is hingedly connected with one end of the wedge-shaped adjusting plate 3 through an adjustable connecting rod 41. The telescopic movement of the telescopic component 4 can drive the wedge-shaped adjusting plate 3 to make axial reciprocating movement from the hydraulic support 2 to the wedge-shaped adjusting plate direction, thereby adjusting the posture of the middle trough 1. The posture of the middle trough 1 is accurately adjusted to ensure that the material can maintain the best flow state during conveying.

[0040] In the embodiment, the trough body 11 further comprises an inclined bottom plate 13 in contact with the wedge-shaped adjusting plate 3, which cooperates with the wedge-shaped adjusting plate 3 to adjust the height of the trough body 11 under the action of the telescopic component 4. The bottom of the inclined bottom plate 13 is designed with an inclined surface matching the shape of the wedge-shaped adjusting plate 3 to ensure that the two can closely fit when in contact, reducing the gap and friction. This design enables the wedge-shaped adjusting plate 3 to smoothly push the inclined bottom plate 13 when moving under the drive of the telescopic component 4, thereby achieving adjustment of the height of the trough body 11.

[0041] In the embodiment, the height of the wedge-shaped adjusting plate 3 decreases linearly or nonlinearly from one end connected with the telescopic component 4 to the other end away from the telescopic component 4. The wedge-shaped adjusting plate 3 moves with the telescopic movement of the telescopic component 4, so that the entire middle trough 1 can naturally form a wave shape during adjustment. This wave-shaped design greatly changes the flow characteristics of the material on the inclined surface, effectively slows down the sliding speed of the material, and reduces the impact force and wear caused by high-speed sliding. In addition, the wave-shaped middle trough 1 not only slows down the material sliding, but also enables the material to be more evenly distributed during conveying, reducing the phenomenon of unstable conveying caused by material accumulation or local absence, further improving the safety and stability of material conveying. The wave-shaped middle trough 1 effectively reduces the impact force and wear degree on the adjusting device.

[0042] In a feasible embodiment, in order to realize the precise adjustment of the posture of the middle trough 1, the adjustment device of the present application further comprises an inclination sensor 5 and the control system. The inclination sensor 5 is arranged in the baffle groove 12 at the bottom of the middle trough 1, and is used to obtain the inclination information of the middle trough 1 with respect to the ground in real time. The inclination sensor 5 comprises a transverse inclination sensor 51 and a longitudinal inclination sensor 52, which are respectively used to detect the inclination information of the middle trough 1 in the vertical direction and the parallel direction with respect to the working face advancing direction of the trough body 11.

[0043] In the present embodiment, the control system is electrically connected or communicatively connected with the inclination sensor 5 and the driving mechanism of the telescopic component 4, receives the inclination information transmitted by the inclination sensor 5, and controls the telescopic length of the telescopic component 4 according to the preset posture adjustment strategy, so as to realize the dynamic adjustment of the posture of the middle trough 1. Specifically, the inclination sensor 5 is installed at the bottom of the middle trough 1 in the baffle groove 12. The inclination sensor 5 is composed of a transverse inclination sensor 51 and a longitudinal inclination sensor 52, which are accurately installed in the baffle groove 12 at the bottom of the middle trough 1, so as to ensure that the inclination changes of the middle trough 1 in the vertical direction and the parallel direction with respect to the working face advancing direction of the trough body 11 can be accurately captured.

[0044] In the present embodiment, by obtaining and processing the inclination information in real time, the control system can accurately calculate and adjust the posture of the middle trough 1, reduces the manual intervention and errors, and improves the adjustment accuracy.

[0045] In the present embodiment, the telescopic component 4 adopts a bidirectional telescopic structure, and can perform axial telescopic movement between the hydraulic support 2 and the wedge-shaped adjusting plate 3. In addition, the telescopic component 4 also has a locking function, and can be automatically or manually locked after being telescoped to a predetermined position, so as to ensure that the adjusted posture is stable and reliable.

[0046] In a feasible embodiment, the posture adjustment method of the middle trough of the scraper conveyor of the present application comprises the following steps: S1: starting the control system, the control system has an algorithm and logic stored therein, and can quickly process and analyze the received data. By comparing the actual inclination with the target inclination, the control system can quickly calculate the adjustment amount to be performed. The control system obtains the initial inclination information of the middle trough 1 with respect to the ground through the inclination sensor 5, and sends the inclination information to the control system.

[0047] S2: The control system receives the inclination information, and determines whether the inclination information is greater than a first set value, i.e., a threshold value triggering adjustment. Specifically, the first set value is thirty. If the control system determines that the received inclination is greater than thirty, it sends an instruction to the driving mechanism of the telescopic component 4 to drive the telescopic component 4 to extend or retract, and simultaneously changes the posture of the middle groove 1 in cooperation with the wedge-shaped adjusting plate 3. During the entire adjustment process, the inclination sensor 5 continuously monitors the change of the inclination of the middle groove 1 and feeds back the latest data to the control system. The control system continuously adjusts the movement of the telescopic component 4 according to the feedback data until the inclination of the middle groove 1 with respect to the ground is less than the first set value.

[0048] S3: When the posture of the middle groove 1 is adjusted to the preset standard, the control system records the current state and ends the adjustment process, and waits for the next adjustment instruction. After the adjustment is completed, the control system also stores the inclination information before and after adjustment, adjustment strategy and adjustment result data into the database for subsequent analysis and optimization.

[0049] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with the preferred embodiment, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the above-mentioned technical content without departing from the scope of the technical solution of the present application, and the equivalent embodiments with equivalent changes are equivalent. The embodiments in the above-mentioned embodiments can be further combined or replaced, but as long as it does not deviate from the content of the technical solution of the present application, any simple modification, equivalent change and modification of the above-mentioned embodiments according to the technical essence of the present application are still within the scope of the present application.
