Description

Technical Field This invention relates to the field of mining and conveying technology in fully mechanized coal mining faces, specifically to the tail section of a scraper conveyor with automatically adjustable azimuth angle. Background Technology

[0001] The tail section of a scraper conveyor is a crucial component. Since the tail drive unit is typically single-sided, unevenness is unavoidable. During the forward movement of the conveyor, supports are needed to adjust the tail drive unit to move it as horizontally or at an angle along the direction of travel. Poor control can lead to slippage or bottoming out. This invention addresses these challenges by proposing an automatically adjustable tail section for the scraper conveyor. The tail drive unit and the tail pusher unit are designed as a hinged structure, connected by a hydraulic cylinder. An industrial tilt sensor, electrical control box, and hydraulic control system control the extension and retraction of the hydraulic cylinder, adjusting the angle between the tail drive unit and the tail pusher unit in real time, thereby preventing slippage or bottoming out of the tail drive unit. Summary of the Invention

[0002] The purpose of this invention is to provide a scraper conveyor tail section with automatic adjustment of the direction inclination angle, which can adjust the included angle between the tail drive section and the tail push section in real time, thereby avoiding the tail drive section from slipping or getting stuck on the bottom.

[0003] The objective of this invention is achieved through the following technical solution: The tail section of an automatically adjustable scraper conveyor consists of an electrical control box 1, a hydraulic control system 2, a hydraulic cylinder, pin assembly I 4, pin assembly II 5, a tail drive unit 6, a tail pusher unit 7, and an industrial tilt sensor 8. The main structures at the tail end of this automatically adjustable tilting scraper conveyor are the tail drive section 6 and the tail push section 7. Both are designed with hydraulic cylinder connecting lugs for mounting hydraulic cylinders. The tail drive section 6 and the tail push section 7 are connected by pin assembly I4, forming a hinged structure. Furthermore, the industrial tilt sensor 8 can collect the tilt information of the tail drive unit 6 in real time, and transmit the collected information to the electrical control box 1. The electrical control box 1 compiles the tilt information and gives instructions to the hydraulic control system 2, indirectly controlling the extension and retraction of the hydraulic cylinder 3. The hydraulic control system 2 can be connected to the electrical control box 1 and the industrial tilt sensor 8 to automatically adjust the tilt angle, and can also be manually adjusted: when needed, the hydraulic control system 2 can be manually controlled to extend the hydraulic cylinder 3 to a certain length to solve the problem of drifting during the pushing process; the hydraulic control system 2 can also be manually controlled to retract the hydraulic cylinder 3 to a certain length to solve the problem of bottoming out during the pushing process. The beneficial effects of the present invention are mainly reflected in the following aspects: The present invention improves the design structure by designing the tail drive part 6 and the tail push part 7 as a hinge structure, and uses a hydraulic cylinder 3 to connect the tail drive part 6 and the tail push part 7 to form a triangular integral structure. The structure is reliable and compact, avoiding the loosening and loss caused by traditional bolt connections.

[0004] The essential features and significant advancements of this device lie in its innovative use of an industrial tilt sensor 8 to collect real-time tilt information from the tail drive unit 6, transmitting it to the electrical control box 1. The electrical control box 1 then processes this tilt information and sends commands to the hydraulic control system 2, indirectly controlling the extension and retraction of the hydraulic cylinder 3. Furthermore, the hydraulic control system 2 can be manually controlled to extend the hydraulic cylinder 3 a certain length to prevent slippage during the pushing process; it can also be manually controlled to retract the hydraulic cylinder 3 a certain length to prevent bottoming out during the pushing process. This avoids the need for manual intervention in cases of slippage and bottoming out, ensuring the safety of operators. Attached Figure Description

[0006] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all of them.

[0007] The method of using this invention is as follows: First, the tail pusher 7 and the tail transmission 6 are connected and fastened using pin assembly I. Then, a hydraulic cylinder 3 is installed between the tail pusher 7 and the tail transmission 6 and fixed using pin assembly II. The industrial tilt sensor 8 is installed above the tail transmission 6. Finally, the industrial tilt sensor 8 is connected to the electrical control box 1 using a quick-connect cable, and the electrical control box 1 is connected to the hydraulic control system 2 using a high-pressure hose. The hydraulic control system 2 is then connected to the hydraulic cylinder 3.

[0008] Without human intervention, this invention transmits real-time tilt signals to the hydraulic control system 2 via an industrial tilt sensor 8. When the industrial tilt sensor 8 detects a slippage signal from the tail drive unit, the hydraulic control system 2 issues a cylinder extension command to the hydraulic cylinder 3. At this time, an angle β is generated between the tail push unit 7 and the tail drive unit 6. Figure 5 As shown: When the hydraulic support pushes the slide in the next step, the tail drive unit will show a downward trend until the drifting signal gradually disappears and the hydraulic cylinder 3 gradually returns to the zero position; when the industrial tilt sensor 8 collects the bottoming signal of the tail drive unit, the hydraulic control system 2 will give the hydraulic cylinder 3 a retraction command. At this time, an angle ε is generated between the tail push unit 7 and the tail drive unit 6, as shown. Figure 5 As shown, when the hydraulic support pushes the slide in the next step, the tail drive unit will exhibit an upward trend until the bottoming signal gradually disappears, and the hydraulic cylinder 3 gradually returns to zero. Furthermore, this invention also allows manual operation of the hydraulic control system 2 to adjust the angle between the tail push unit 7 and the tail drive unit 6. This invention fundamentally achieves the requirements of reduced manpower and unmanned operation, avoiding the need for manual intervention in cases of drifting or bottoming out, thus avoiding wasted manpower and safety risks.
