Tensioning and fixing method and device for mining endless rope winch tail wheel system

Abstract

The invention discloses a tensioning and fixing method and device for a mining endless rope winch tail wheel system. A bearing device with the cross section being an m-type or n-type steel structure framework and a tensioning cylinder are mounted in the underground mounting place, and a cylinder shaft seat is arranged in the space of the steel structure framework and mounted on a pressure bearingfoot plate; the tensioning cylinder is mounted on the cylinder shaft seat through a shaft of the tensioning cylinder; during arrangement of the endless rope winch tail wheel system, all that is required is to mount return wheels of a winch traction rope at an extension rod head of the tensioning cylinder, and the winch traction rope can be properly tensioned by adjusting the extension length of aworking rod of the tensioning cylinder. The winch tail rope can be tensioned through the tensioning cylinder, slipping can be eliminated, a balance wheel is omitted particularly for a double-rope typewinch tail wheel system, and the structure is more simplified. If an automatic pressure regulator is designed on the tensioning cylinder, the tension degree of the winch traction rope can be balancedautomatically with the magnitude of the winch traction force.

Description

technical field [0001] The invention relates to the transportation equipment under the coal mine, in particular to the transportation equipment of the endless rope winch. Background technique [0002] There are single rope type and double rope type in the transportation mode of infinite rope winch in coal mine. The single-rope endless rope winch is transported with a single-drum winch at one end and a turning wheel at the other end, and the turning wheel is required to be tightened on the infrastructure. For heavy-duty transportation, double-rope endless rope winch transportation is mostly used. Double-rope endless rope winch transportation methods such as Figure 7 Shown, one end is a double drum winch 17, and one end is a tail wheel system. The tail wheel system is provided with a balance wheel 20, and the balance wheel 20 is hung with two return wheels 11 by the return pulley stay rope 14, requiring the balance pulley 20 to be tightened on the fixed point 19 of the infr...

AI Technical Summary

Problems solved by technology

The current infrastructure generally digs deep foundation pits and pours a large amount of concrete, which requires a lot of manpower, material resources, time, etc., and requires a certain setting time before it can be used, which affects the timely mining of coal seam working faces.

Because the coal mining site is often changed, the facility cannot be reused after being used once, and a new foundation needs to be built, which not only affects the timely mining of the next coal seam working face, but also causes great waste

[0003] Furthermore, the single-rope return wheel cannot actively adjust the tension, and the winch drum often slips, which makes the transportation efficiency low

Although the balance of the double-rope return wheel 11 is regulated by the balance wheel 20, the fixed point 19 of the balance wheel stay rope 15 of the balance wheel 20 is a fixed point, so the tension cannot be adjusted actively
