Description

Technical Field

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

[0002] The scraper conveyor is the core transportation equipment in the coal mining working face. The middle trough occupies up to 80% of the main structure of the scraper conveyor, becoming the key component and main component of the equipment. Its reliability has a direct impact on the working efficiency of the scraper conveyor.

[0003] In the mining environment with an inclined or steep inclination of the coal seam with an inclination of more than 30 degrees, due to the large inclination of the working face, a slight change in the floor may cause the stability of the equipment to be impaired. More importantly, when the inclination of the coal seam is greater than the natural repose angle of the gangue, the gangue will tend to slide downward, further aggravating the instability of the equipment. At present, the maximum applicable inclination angle of my country's scraper conveyor is still limited to coal seams less than 30°. Once the inclination of the coal seam exceeds this range, the scraper conveyor equipment will face a series of severe challenges, including the unbalanced sliding of the conveyed materials and the huge impact load of the materials on the equipment. These problems can easily lead to the failure of equipment parts, which in turn makes the mining technology development level of large-angle coal seams significantly lag behind that of gently inclined coal seams.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Example like Figure 1-7As shown, a device for adjusting the posture of the middle trough of a scraper conveyor, the adjustment device includes the following parts: a middle trough 1, which is arranged on the working surface and serves as a channel for material transportation. The middle trough 1 includes a plurality of trough bodies 11 connected in sequence; a wedge-shaped adjustment plate 3 is provided at the bottom of the trough body 11, which is used to change the inclination angle of the middle trough 1; a hydraulic support 2, which is arranged at the bottom of the middle trough 1 and between two adjacent trough bodies 11, and plays a role in supporting the trough body to achieve 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 to the hydraulic support 2, and the other end is hinged to one end of the wedge-shaped adjustment plate 3 through an adjustable connecting rod 41, and the telescopic movement of the telescopic component 4 can drive the wedge-shaped adjustment plate 3 to make an axial reciprocating movement from the liquid support 2 to the wedge-shaped adjustment plate, thereby adjusting the posture of the middle trough 1. The present invention ensures that the material can maintain the best flow state during the transportation process by accurately adjusting the posture of the middle trough 1.

[0026] In this embodiment, the trough body 11 further includes an inclined bottom plate 13 that is in contact with the wedge-shaped adjustment plate 3. The inclined bottom plate 13 cooperates with the wedge-shaped adjustment 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 that matches the shape of the wedge-shaped adjustment plate 3 to ensure that the two can fit tightly when in contact, reducing gaps and friction. This design allows the wedge-shaped adjustment plate 3 to smoothly push the inclined bottom plate 13 when it moves under the drive of the telescopic component 4, thereby achieving the adjustment of the height of the trough body 11.

[0027] In this embodiment, the height of the wedge-shaped adjustment plate 3 decreases linearly or nonlinearly from the end connected to the telescopic component 4 to the end away from the telescopic component 4. The wedge-shaped adjustment plate 3 moves with the telescopic movement of the telescopic component 4, so that the entire middle groove 1 can naturally form a wave shape during the adjustment process. 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 wavy middle groove 1 not only slows down the sliding of the material, but also allows the material to be more evenly distributed during the transportation process, reducing the transportation instability caused by material accumulation or partial loss, and further improving the safety and stability of material transportation. The wavy middle groove 1 effectively reduces the impact force and wear on the adjustment device.

[0028] In a feasible implementation, in order to achieve accurate adjustment of the posture of the middle trough 1, the adjustment device of the present invention further includes 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 and the ground in real time. The inclination sensor 5 includes a lateral 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 direction of advancement of the working surface perpendicular to and parallel to the trough body 11.

[0029] In this 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 a preset posture adjustment strategy, thereby realizing dynamic adjustment of the posture of the middle slot 1. Specifically, the inclination sensor 5 is installed at the bottom of the middle slot 1, located in the baffle slot 12. The inclination sensor 5 consists of a lateral inclination sensor 51 and a longitudinal inclination sensor 52, which are respectively precisely installed in the baffle slot 12 at the bottom of the middle slot 1 to ensure that the inclination changes of the middle slot 1 in the direction of advancement of the working surface perpendicular to and parallel to the slot body 11 can be accurately captured.

[0030] In this embodiment, by acquiring and processing the inclination information in real time, the control system can accurately calculate and adjust the posture of the middle slot 1, thereby reducing manual intervention and errors and improving the accuracy of adjustment.

[0031] In this 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 adjustment plate 3. In addition, the telescopic component 4 also has a locking function, and can be automatically or manually locked when it is extended to a predetermined position to ensure that the adjusted posture is stable and reliable.

[0032] In a feasible embodiment, the method for adjusting the posture of the middle trough of a scraper conveyor of the present invention comprises the following steps: S1: starting the control system, the control system has built-in stored algorithms and logics, and can quickly process and analyze the received data. By comparing the actual inclination angle with the target inclination angle, the control system can quickly calculate the amount of adjustment required. The control system obtains the initial inclination information of the current middle trough 1 and the ground through the inclination sensor 5, and sends the inclination information to the control system.

[0033] S2: After receiving the inclination information, the control system determines whether the inclination information is greater than a first set value, that is, the threshold for triggering adjustment. Specifically, the first set value is thirty. If the control system determines that the received inclination is greater than thirty, it sends a command to the drive mechanism of the telescopic component 4 to drive the telescopic component 4 to extend and retract, and at the same time cooperate with the wedge-shaped adjustment plate 3 to change the posture of the middle slot 1. During the entire adjustment process, the inclination sensor 5 continuously monitors the inclination changes of the middle slot 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 angle between the middle slot 1 and the ground is less than the first set value.

[0034] S3: When the posture of the middle slot 1 is adjusted to the preset standard, the control system records the current state and ends the adjustment process, waiting for the next adjustment instruction. After the adjustment is completed, the control system also stores the inclination information before and after the adjustment, the adjustment strategy and the adjustment result data in the database for subsequent analysis and optimization.

[0035] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
