Problems solved by technology

[0004] The purpose of the present invention is to overcome the winding of the multi-layer steel wire rope of the existing hoist and the upper steel wire rope will seriously squeeze the originally loose steel wire rope of the lower layer, resulting in the premature failure of the lower layer steel wire rope. The on-load installation method of the small friction winch, the invention can ensure that the steel wire rope wound in multiple layers on the reel is wound on load, so as to ensure that the steel wires of the steel wire rope are tightly bonded, the force is balanced, and there is no deformation, which can improve the service life of the steel wire rope

Embodiment 1

[0026] A derrick 1 is correspondingly arranged above the wellhead 9, a sky wheel 2 is arranged above the derrick 1, and the sky wheel 2 is vertically arranged corresponding to the wellhead 9; a friction trolley 7 is arranged on one side of the derrick 1, and a wire rope reel 6 is arranged on one side of the friction trolley 7; the friction trolley 7 and the derrick 1 A hoist 8 is arranged between them; the sky wheel 2 is arranged on the same line as the friction trolley 7, the hoist 8 and the wire rope reel 6; A wire rope head is set on the top, and a lifting container 3 is set below the wire rope on the wellhead 9 corresponding to the rope clamping device 5; the container moving pulley 4 is set in the upper center of the lifting container 3; ; Set the clamping buckle 10 between the wire rope head and the lifting container 3; when the wire rope is installed, the lifting container 3 is lifted while the wire rope is wound on the hoisting machine 8 drum with load.

Embodiment 2

[0028] The wire rope head of the wire rope roll 6 is pulled out and wound on the friction trolley 7, and the wire rope roll 6 is driven by rotating the friction trolley 7 to pull out the wire rope and wrap it on the sky wheel 2; Above; clamp the wire rope rope head in the rope head rope clamping device 5 above the horizontal frame; drive the wire rope into the well by the weight of the friction trolley 7 and the lifting container 3, and stop the rotation when the friction trolley 7 is placed into the well to a preset depth.

Embodiment 3

[0030] The middle wire rope is fixed above the horizontal frame by another rope clamping device 5; then, the tail of the wire rope is removed from the wire rope roll 6, and it is installed and fixed on the hoist 8; after the end of the wire rope is fixed, remove the middle wire rope clamping device 5. .

Abstract

Disclosed is an on-load installation method for a small friction winch for winding of a multi-layer steel wire rope of a hoister. According to the small friction winch for winding of the multi-layer steel wire rope of the hoister, a container movable pulley is arranged above the center of a hoisting container; the steel wire rope is arranged between a steel wire rope coil and a friction trolley and between a head sheave and the hoisting container 3; the steel wire rope is installed to hoist the hoisting container, and meanwhile, the steel wire rope is wound around a winding drum of the hoister in an on-load mode; after the hoisting container is supported steady by a support plate, a rope clamping device of a steel wire rope end is released; the container movable pulley is taken down; the steel wire rope is released and pulled to be straight; and the steel wire rope end is fixedly installed on the hoisting container through a clamping buckle. According to the method, it is ensured that the multi-layer steel wire rope is wound around the winding drum in the on-load mode, so that it is ensured that steel wires of the steel wire rope are combined tightly and closely, stress is balanced and deformation is avoided; the service life of the steel wire rope can be prolonged.

Description

technical field [0001] The invention relates to a multi-layer steel wire rope winding device of a mine hoist, in particular to a load-loading installation method of a friction small winch for winding the multi-layer wire rope of a hoist. Background technique [0002] At present, the mine hoist is one of the important and key equipment in the mine, mainly used for coal mine, metal mine and non-metal mine hoist and lower personnel, to lift coal, ore and transportation materials and equipment. It is an important means of transportation to connect the well and the well. It occupies a very important position in the mine and is an important equipment of the mine. The mine hoist is developed from the hand-cranked reel. With the development of science and technology, the hoist has developed from the KJ type to the JKA type, and from the XKT type and the XKTB type to the current JK type winding mine hoist. [0003] The existing winding hoists in my country are mostly used for singl...
