Abstract
The utility model discloses a dual-brake floor type friction wheel lifting device. The dual-brake floor type friction wheel lifting device comprises a winch, a lifting steel wire rope, a derrick, a rope guide wheel, a hoisting sheave, lifting containers and a tail rope, wherein the derrick is fixedly arranged on the ground, the winch is arranged on one side of the derrick, the rope guide wheel and the hoisting sheave are fixed on the upper portion of the derrick, the two ends of the lifting steel wire rope are connected with the lifting containers respectively, the lifting steel wire rope passes around the hoisting sheave and then is wound on a friction wheel of the winch, brake discs are arranged on two sides of the hoisting sheave respectively, each brake disc is provided with a disc type brake, and a control pipeline of each disc type brake is connected to a brake control end of the winch. The dual-brake floor type friction wheel lifting device can effectively avoid the phenomenon that the steel wire rope slides on the friction wheel, guarantees hoisting safety and has the advantages of being reasonable in structure, safe to operate, reliable in brake and the like.
Description
Technical field:
The utility model belongs to colliery floor type friction wheel bont technical field.
Background technology:
Frictional geared bont is due in the time promoting, can not be subject to rope woolding to hold quantitative limitation, can adapt to different well depths and the large feature of lifting capacity, along with the extension of the pit mining degree of depth and the raising of output, increasing Coal Exploitation carries out Lifting Convey with ground-type multi-cable friction wheel bont.Current floor type friction wheel bont is mainly made up of winch, hoisting cable, derrick, sheave, head sheave, lifting container, tail rope etc., when work, hoisting cable two ends are connected with respectively lifting container, steel rope is wound on the friction wheel of winch after walking around head sheave again, rising of two containers, another decline, in the time that one of them rises to well head, another drops to shaft bottom, and raising efficiency is higher.For winch is implemented to safety arrestment, on the friction wheel of winch, be provided with disc-brake, when bont is implemented braking, disc-brake is clamped the brake disc of winch friction wheel, relies on the friction force between hoisting cable and winch friction wheel to realize braking effect.In actual use, due to lifting container weight to affect inertia larger, there will be the sliding phenomenon of steel rope on friction wheel, impact promotes safety, although bont is designed with the speed run curve of regulation, for mine harsh environment, the friction force of depending merely between hoisting cable and winch friction wheel is realized operation and brakes safe and reliable not enough.
Utility model content:
The purpose of this utility model is to provide a kind of rational in infrastructure, safe in operation, braking failure-free double brake floor type friction wheel bont.
To achieve these goals, the utility model comprises: winch, hoisting cable, derrick, sheave, head sheave, lifting container, tail rope, derrick is fixedly installed on the ground, winch is arranged on derrick one side, sheave and head sheave are fixed on derrick top, hoisting cable two ends are connected with respectively lifting container, hoisting cable is wound on the friction wheel of winch after walking around head sheave again, it is to be respectively arranged with brake disc on the both sides of head sheave, on brake disc, be provided with plate disc brake, the control pipeline of plate disc brake is connected to the braking control end of winch.
In this sample device busy process, need to brake time, can utilize operator's station friction wheel and head sheave to be implemented to double brake simultaneously, between hoisting cable and friction wheel and head sheave, produce friction force simultaneously, improve braking effect, can effectively avoid the sliding phenomenon of steel rope on friction wheel, ensure to promote safety, there is the features such as rational in infrastructure, safe in operation, braking be reliable.
Brief description of the drawings:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is member connection structure schematic diagram of the present utility model.
Fig. 2 is head sheave brake component structural representation.
Detailed description of the invention:
As seen from Figure 1, Figure 2, the utility model comprises: winch 1, hoisting cable 2, derrick 3, sheave 4, head sheave 5, lifting container 6, tail rope 8.Derrick 3 is fixedly installed on wellhead ground 7, and derrick adopts steel to be processed into, should be firmly safe and reliable.Winch 1 is arranged on the ground of derrick one side, and sheave 4 is fixed on derrick 3 tops with head sheave 5, and hoisting cable 2 two ends are connected with respectively lifting container 6, and hoisting cable 2 is wound on the friction wheel of winch after walking around head sheave again.In order to ensure operating steadily up and down of two lifting containers, be connected with tail rope 8 in the bottom of two lifting containers.Be respectively arranged with brake disc 11 on the both sides of head sheave 5, on brake disc, be provided with plate disc brake 10, control pipeline 9 on plate disc brake 10 is connected to the braking control end of winch, friction wheel and the head sheave of winch can be braked simultaneously, between hoisting cable and friction wheel and head sheave, produce drag friction power simultaneously, improve integral stop effect.
