Temporary support device for tunneling machine EBZ160 advanced support device for tunneling machine

Description :

Product details of airborne temporary support device. Product introduction of airborne temporary support device aims to solve the shortcomings of manual pipe penetration and beam support in coal mine tunnel development, improve the mechanization level of comprehensive excavation, and achieve fast and safe excavation technology. Our company has developed an airborne temporary support device to achieve safe, reliable, and fast support technology for the aerial roof area, greatly improving the safety of excavation production, significantly increasing production efficiency, and having great economic and social benefits.

　　The airborne temporary support device is a complete solution proposed by our company to address the problem of temporary support for head-on excavation. Its appearance will change the traditional temporary support form of the beam before pipe penetration, effectively applying initial support force to the roof, truly playing an active safety protection role, significantly reducing the temporary support time, greatly reducing the labor intensity of employees, and significantly improving labor efficiency.

　　The device has a clever structure, reliable performance, easy installation, wide applicability to tunnels, and can be matched with multiple models. The working process complies with the relevant provisions of the Coal Mine Safety Regulations. The product has undergone multiple rigorous on-site inspections and has received warm praise from frontline workers.

　　The main characteristics of the airborne temporary support device are: 1. Large support area and high initial support force.

　　2. It can be smoothly flipped open and retracted under low roof roadway conditions.

　　3. Using the pump station of the tunneling machine as power, fully hydraulic control, smooth operation, and rapid deployment are beneficial for self-protection of the machine.

　　4. The hydraulic pipelines with clever structure, reasonable layout, and movable mechanism all use high-pressure rubber hoses.

　　5. Significantly reducing temporary support time, significantly reducing employee labor intensity, significantly improving labor efficiency, and effectively ensuring the safety of anchoring work.

　　Structure and working principle of airborne temporary support device

　　Structure: Composed of top beam frame, connector, main frame, oil cylinder, plug-in bidirectional lock, high-pressure oil pipeline, diversion and collection valve, two position three-way valve, control and operation valve, etc.

　　Principle: During operation, the pump station of the tunneling machine is used to supply oil. The oil passes through a two-way three-way valve, an overflow valve, and an operating valve. It is then diverted by a diversion and collection valve and enters a two-way lock,

　　The two-way lock is opened to enter the oil cylinder, the main frame is opened and raised, and the top frame is opened and raised until the desired height and angle are reached.

　　Scope of application of airborne temporary support device

　　Suitable for rectangular, inclined roof, trapezoidal, and arched tunnels with a height of 2.5-4.5 meters. Can be matched with various models of tunneling machines.
