telescopic belt conveyor with rubberized roller covers

Through flexible body structure, the telescopic belt conveyor can realize rapid conveyor path adjustment according to the advancement progress of the mining face, so as to meet the demand for synchronous transportation of high-efficiency mining and digging. The electrical system of the whole machine is equipped with explosion-proof function, which can be safely applied in gas and coal dust environment.

Features of telescopic belt conveyor:

1. Synchronized retractable body structure: the equipment is equipped with tape retracting system and belt storage device, which can realize free extension or shortening of the body according to the change of the digging distance to ensure that the transportation system is always close to the working face.
2. Quick assembly and disassembly system: the equipment adopts plug-in, boltless detachable bracket, which greatly reduces the labor intensity of underground construction and improves the relocation and maintenance efficiency.
3. Electric tensioning system with tension indication: the tape tensioning device is driven by an electric winch with real-time tension indication, which is convenient for adjusting the running status and preventing slippage and deflection.
4. Highly generalized parts: including rollers, drums and other core components using a unified standard, interchangeable, easy inventory management and maintenance and replacement.
5. Strong rubber wrapped roller structure: the main drive roller outer layer adopts high adhesion rubber wrapping structure to improve driving efficiency and adapt to high load and long time continuous operation.
6. A variety of installation methods are compatible: the intermediate frame can be installed on the ground or suspended, adapting to different roadway terrain and support conditions, and improving the overall flexibility of the system layout.

Technical advantages of telescopic belt conveyor:

1. Continuous transportation, automatic adaptation to the front: adapt to the rhythm of coal mining face advancement, without the need to frequently adjust the layout of the conveyor, reducing the downtime and improving production continuity.
2. Safe and reliable explosion-proof performance: the electronic control system and electrical components have mining explosion-proof certification, suitable for underground operating environment with the risk of gas or coal dust explosion.
3. Highly adaptable structural design: It supports non-linear roadway arrangement, slope installation and flexible arrangement in narrow space, with strong adaptability.
4. Strong system maintenance simplicity: due to the high versatility of the module and the simplified connection structure, it makes maintenance and troubleshooting more convenient and saves operation and maintenance costs.
5. Strong carrying capacity, long distance: can meet the long distance, large capacity of coal, gangue efficient transportation needs, is an important part of the main transportation trunk line underground.

The working principle of telescopic belt conveyor:

The conveyor mainly relies on the electric drive pulley to drive the tape running, the material enters the conveyor belt through the reproduction point, and moves to the end with the tape to complete the transfer or unloading. In coal mine applications, the end of the conveyor belt is usually connected with the scraper transfer machine or roadheader belt conveyor to realize the material connection between the working face and the main transportation system.

The belt expansion mechanism is the core of the equipment, through the tape retractor located in the head or middle of the machine, with the roller tensioning system for length adjustment, the whole process is controlled by the PLC system, automatically adapting to the advancement distance of the mining face, to ensure that the conveyor system does not interrupt the operation.

The tensioning system applies constant tension to the belt through the electric winch, while the tension indicator monitors the real-time status to ensure that the belt always maintains the appropriate tension during operation, preventing material spreading or slipping caused by slackness.

Application field of telescopic belt conveyor:

1. Comprehensive Mining Face Shunchan Transportation: as a part of comprehensive mining system, it realizes the efficient transfer of raw coal from the working face to the main transport system.
2. Tunneling roadway material transportation: supporting the use of tunneling equipment, real-time clearing of slag, gangue and other materials, to enhance the efficiency of tunneling.
3. High-yield and high-efficiency mine main transportation trunk line: adapt to the long-distance, heavy-duty transportation needs, is an important tool for modern mines to improve the level of automation.
4. Non-coal mine and subway construction: used for conveying rock, slag and other materials for continuous transportation, effectively reduce the pressure of manual transfer.
