Description

Technical Field

[0001] This invention relates to the field of underground mining, transportation and conveying technology in coal mines, and particularly to a tracked traction tail device of a continuous telescopic transport system in a continuous mining and transportation collaborative transport system. Background Technology

[0002] With the rapid development of automation and intelligence in coal mines, flexible and mobile transfer machines and conveyor belts are being used more and more widely in the supporting conveying system after tunneling. The moving distance and flexibility of the transfer machine and the moving flexibility and storage belt length of the tail of the conveyor belt directly affect the tunneling distance and efficiency of the integrated mining machine, and thus largely determine the production capacity and efficiency of the coal mining face.

[0003] Currently, the commonly used working method in mining faces involves the sequential overlapping and coordination of a mining machine, a transfer conveyor, and a roadway belt conveyor. The transfer conveyor following the mining machine often uses a scraper conveyor or a cantilevered truss-type transfer conveyor. The tail of the roadway belt conveyor connected to the transfer conveyor needs to be moved frequently as the working face advances. There are two main methods for moving the tail of the roadway conveyor: one is manual movement, which involves complex procedures, numerous steps, a large workload for dismantling and installation, many safety hazards, a tendency for the conveyor belt to deviate, and a long construction time, directly affecting the normal production of the fully mechanized mining face. The other method is self-moving tail movement, which uses a complex hydraulic device to move the tail. This device is large and heavy, has a complex control system, requires a large workload for installation and maintenance, and has a slow moving speed, similarly affecting the working efficiency of the fully mechanized mining face. Traditional roadway conveyor belt storage devices use a trolley structure for the trolley, with the entire weight of the trolley supported by the bottom wheel frame. This limits the weight of the trolley, and the trolley is relatively short, which means it can support fewer layers of belt, thus limiting the length of the stored belt. Generally, the storage length of roadway conveyors is around 200 meters, which is too short to meet the requirements of efficient underground tunneling. Summary of the Invention

[0004] The purpose of this invention is to provide a tracked traction tail device for a continuous telescopic transport system, which serves as the traction component of the continuous telescopic transport system in a continuous mining and transportation collaborative transport system.

[0005] The objective of this invention is achieved as follows: a tracked traction tail device for a continuous telescopic transport system, characterized in that it consists of two parts: a climbing guide mechanism and a tracked traveling mechanism, which are hinged together by a pin.

[0006] The objective of this invention can also be achieved as follows: the climbing guide mechanism consists of a movable support wheel, an inclined guide rail, a support frame I, and an unequal diameter open guide rail; the movable support wheel is installed in a slot below the tail of the support frame I and is fixed with a baffle and bolts; the inclined guide rail is welded above the support frame I; the unequal diameter open guide rail is installed at the tail of the support frame I and is hinged by a pin.

[0007] The tracked traveling mechanism consists of a hydraulic motor, track device, track support frame, electric roller, horizontal guide rail, and support frame II. The track device is installed at both ends of the track support frame. The track support frame is welded to the bottom of support frame II. The horizontal guide rail is welded to the top of support frame II. The electric roller is installed on the frame of support frame II and fixed by bolts.

[0008] The beneficial effects of this invention are:

[0009] This invention, a continuous telescopic transport system, creatively employs a tracked power traction method to move the tail section of the machine, thereby pulling the main body along with it. This enables the continuous telescopic transport system to move autonomously and in real time, achieving continuous transport between the tunneling face and the main roadway during unmanned mining operations. Furthermore, it enables unmanned remote control and fully automated operation, completely changing the traditional situation of relying on manual labor or integrated mining and excavation machines for traction. This reduces the workload of workers and greatly improves the safety of underground coal mines.

[0010] Specifically, firstly, it saves time and manpower. Manually moving the tail section requires 7-8 people and about 3 hours of work, while a self-moving tail section requires 4-5 people and about 1 hour. This invention enables the tail section to move automatically, requiring only one person to operate it locally or remotely. Secondly, it is safe and reliable. Manual methods require support columns, winches, or manual traction, resulting in a large workload, long working hours, and numerous safety hazards. Self-moving tail sections are large and heavy, making transportation and installation difficult, labor-intensive, and increasing safety risks. This invention is small, lightweight, and allows for remote control of its movement. Thirdly, it is simple to operate and requires minimal maintenance. Self-moving tail sections use numerous hydraulic systems, leading to cumbersome operation procedures and high worker skill requirements; the hydraulic structure and pipelines require frequent inspection and replacement of parts, significantly increasing maintenance workload. This invention uses tracks for drive, eliminating the cumbersome hydraulic mechanism, resulting in a simple structure, convenient operation, and remote tail section movement via control buttons.
