Problems solved by technology

The rope traction rail car is driven by a hydraulic winch, which needs to lay special tracks, special switches and supporting reloading equipment. The hydraulic winch has a complicated structure, high requirements for use, inconvenient maintenance, and cooling water is required during work. Traction trucks are less used
Although ordinary endless rope winches are commonly used, it is still difficult for some working faces with narrow roadways, undulating ground, and slopes above 5 degrees to follow the trough. Larger traction, while the current high-power stepless rope winch occupies a large area, and the narrow roadway limits its use; ②The ordinary stepless rope winch transportation system adopts a constant pulling force on the wire rope at the tail wheel, so that the wire rope It has a pre-tension, and the pre-tension generally selects the maximum tension of the wire rope. The tension of the wire rope is very large when the train is going uphill, so the pre-tension of the wire rope in the ordinary endless rope winch transportation system for traction on the slope is very large, because the wire rope is always in the In the state of high tension, it affects the service life of the wire rope

Embodiment Construction

[0023] figure 1 versus figure 2 As shown, the present invention consists of an endless rope winch 1, a wire rope tensioning device 2, a shuttle car 3, a rope pressing device 4, a sheave 5, a rail 6, a wire rope 7, and a tail wheel 8. The wire rope tensioning device 2 is set on the endless rope In front of the rope winch 1, the tail wheel 8 is arranged at the end of the track 6, the rope pressing device 4 is arranged on the slope bottom track, the rope supporting device 5 is arranged on the slope top track, and the wire rope passes through the tensioning device 2.

[0024] image 3 As shown, the endless rope winch 1 has a base 101 fixed on the ground. On one side of the base, an explosion-proof motor 102 and a reducer 105 are arranged along the length direction. An elastic pin coupling is used between the motor shaft and the input shaft of the reducer. 103 connection, that is, a connecting disc is fixed on each of the two shafts, and a number of nylon pins are used to connect t...

Abstract

The invented continuous tractor is composed of non-polar rope hoister, steel cable tension device, shuttle, rope pressing device, rope supporting wheel, rail, steel cable and tail wheel, the non-polar rope hoister is compact in structure, and the tension of steel cable can be regulated automatically. Measures are adopted with respect to safety and protection of steel cable. It is suitable for usein narrow tunnel lanewidth and is convenient in operating, transfering, installing, maintaining, etc. It is good in technical performance and safety.

Description

Technical field [0001] The invention relates to a transportation system suitable for mines with tracks and wire rope traction. Background technique [0002] The continuous tractor is a kind of endless rope winch transportation system. It is powered by the endless rope winch, and the shuttle car is pulled by the wire rope, and the shuttle car is pulled back and forth on the track. In domestic mines, the use of endless rope winches as auxiliary transportation in mines is still very common. They are mainly used in large roadways in mining areas, with simple structure and convenient maintenance. For the transportation along the trough of the working face in the mine, there are ordinary endless rope winches and rope traction trucks. The rope traction rail car is driven by a hydraulic winch and needs to lay special tracks, special turnouts and supporting transfer equipment. The hydraulic winch has a complicated structure, high requirements for use, and inconvenient maintenance. It also...
