Description

Method for setting ground anchor of tail wheel system of endless rope winch for mine and ground anchor device
Technical Field
The invention relates to a coal mine underground transportation technology, in particular to an endless rope winch transportation technology.
Background
In the underground coal mine winch transportation mode, there are endless rope winch transportation modes and single rope type and double rope type modes. One end of the single rope endless rope winch is a single drum winch, and the other end is a tail wheel system; the tail wheel system is provided with a balance wheel with a tensioning function, and each head wheel is hung on the balance wheel, so that the balance wheel is required to be tensioned on an infrastructure. For heavy load transportation, a double-rope endless rope winch transportation mode is mostly adopted. One transportation end of the double-rope endless rope winch is a double-drum winch, and the other end is a tail wheel system. The tail wheel system is provided with a large balance wheel with a tensioning function, and the balance wheel is hung on two return wheels, so that the balance wheel is required to be tensioned on an infrastructure. Whether single-rope or double-rope, are independent of the infrastructure, and sometimes mine cars are required to pass over the infrastructure. The infrastructure is therefore able to withstand not only large gravitational loads but also large tensile loads of the wire ropes and is therefore very strong to build. The existing infrastructure is generally formed by pouring a large amount of concrete for a deep foundation pit, so that a large amount of manpower, material resources, time and the like are needed, and the foundation pit can be used only after a certain solidification time is needed, and timely exploitation of a coal seam working face is affected. Because the coal mining site is frequently changed, the facility cannot be reused after being used once, and a new foundation needs to be reconstructed, so that the timely mining of the next coal seam working face is affected, and great waste is caused.

When the device is used for a single rope winch tail wheel system, an m-shaped steel structure frame is adopted, and when the device is used for a single rope winch tail wheel system, an n-shaped steel structure frame is adopted.
The invention has the positive effects that:
1. the underground hydraulic pressure system can be manufactured in an industrial manner on a well, is directly installed on an underground installation site, and is anchored on a bottom plate of a roadway by an anchor rod during installation, so that manpower, material resources and time are saved.
2. Along with the transformation of the coal mining site, the coal mining site can be disassembled and moved to a new site, and the coal mining site can be manufactured and reused once, so that the construction cost is saved.
3. The steel structure frame has enough space, and the tail wheel system of the winch can be installed in the space without preventing the mine car from passing on the track above the tail wheel system.
4. Can bear the gravity load of the mine car passing on the upper surface and the tension load of the winch.
