CN2799342Y - Rope-expanding coal mine cableway - Google Patents

Abstract

The utility model discloses a rope expanding type coal mine cableway, which comprises a power device, a driving wheel, a steel cable, a cableway hanging chair, a rope supporting wheel, a return wheel, a return wheel frame and a tension pull rope, wherein the driving wheel and the steel cable are arranged on the power device. The cableway hanging chair, the rope supporting wheel, the return wheel, the return wheel frame and the tension pull rope are arranged on the steel cable, and one end of the tension pull rope is connected with the return wheel frame. The tension pull rope passes round a pulley wheel. A weight dropper is hung on other end of the tension pull rope. Four rope expanding wheels are respectively arranged on both sides close to the driving wheel and the return wheel. The steel cable passes round the rope expanding wheels to lead the separation distance between the steel cables which are arranged on both sides of the rope expanding wheels to be larger than the diameter of the driving wheel. The utility model has the advantages that because the rope expanding wheels are added, the separation distance between the steel cables is not limited by the diameter of the driving wheel. When a locomotive is used for conveying goods in a lane, the hanging chair which is arranged on the cableway steel cable does not need to be disassembled. Consequently, workmen's labor intensity is reduced, and labor productivity is improved.

Description

Expand rope formula colliery cableway

Technical field

The utility model relates to a kind of colliery cableway.

Background technology

Spacing between the colliery cableway steel rope of the fixed rope clip of colliery use at present is identical with the diameter of drive wheel, for saving in power, reduce production costs, the diameter of drive wheel can be very not big, if in the shared tunnel of people's goods, colliery, the locomotive owing to also will pass through in the tunnel will be taken off rope clamping device when cargo transport from steel rope, very inconvenient.

Summary of the invention

The purpose of this utility model is the cableway that makes things convenient for goods shared tunnel in people from colliery to use.

The purpose of this utility model realizes in the following way: a kind of expansion rope formula colliery cableway, comprise engine installation, drive wheel is arranged on engine installation, steel rope, the cableway chair lift is arranged on steel rope, the holder rope sheave, return sheave, circuitous wheel carrier, tensioning stay cord, tensioning stay cord one end is connected on the circuitous wheel carrier, the tensioning stay cord is walked around pulley, and the other end is hung a weight, and 4 expansion rope sheaves respectively are being housed near the both sides of drive wheel and return sheave, steel rope is walked around the expansion rope sheave, makes spacing between the steel rope of both sides greater than the diameter of drive wheel.

Expand the diameter of the lower rim diameter of rope sheave greater than upper rim.

The utlity model has following beneficial effect, owing to increased the expansion rope sheave, make spacing between the steel rope not be subjected to the restriction of drive wheel diameter, when in the tunnel, freighting with locomotive, do not need the chair lift on the cableway steel rope is taken off, alleviate working strength of workers, improved labor efficiency.
