Abstract
The utility model discloses a hoisting sheave device of a floor type multi-rope friction hoist, belongs to hoisting sheave devices of a mine hoist, and aims at providing the hoisting sheave device which is stable to operate, long in service life, convenient to maintain and low in cost. The hoisting sheave device comprises a hoisting sheave shaft supported on a bearing block, a fixed hoisting sheave, a clamping ring, a plurality of movable hoisting sheaves arranged between the fixed hoisting sheave and the clamping ring, a connecting shaft fixed at one end of the hoisting sheave shaft and a decoder fixed on the bearing block and connected with the connecting shaft through a coupler, wherein the fixed hoisting heave and the clamping ring are fixed on the hoisting sheave shaft. A bush fixedly connected with the movable hoisting heaves (2) is arranged between the shaft holes of the movable hoisting sheaves (2) and the hoisting sheave shaft (6), and the bush is formed by combining two semicircular cylindrical bearing bushes (5). The hoisting sheave device of the floor type multi-rope friction hoist reduces abrasion of a hoisting sheave shaft hole or the hoisting sheave shaft, prolongs service life, overcomes defects of long maintenance time, high cost and the like, and is an improved structure of the hoisting sheave device of the mine hoist.
Description
Technical field
The utility model relates to a kind of mine hoist head sheave apparatus, relates in particular to a kind of console model multi-rope friction hoist's head sheave device.
Background technology:Mine hoist is one of the key equipment in mine, is contact mine important transportation instrument up and down, is called as " the throat equipment " in mine; And the console model multi-rope friction hoist's head sheave device is the vitals for mine hoist, is mainly used in rest and guiding steel cable.
At present, the floating sheave of console model multi-cables hoist adopts the mode that directly cooperates with day wheel shaft to be installed on day wheel shaft usually, and lubricating system is not set; Therefore floating sheave, quick abrasion large with friction between day wheel shaft, service life are short, must change frequently.In addition, because the floating sheave size is larger, maintain and replace is cumbersome, has many defectives such as maintenance time is long, cost is high, work capacity is large.Moreover, because steel rope is less with friction coefficient between fixing head sheave and the floating sheave, so skids easily and affect running stability; Simultaneously, steel rope also easily Fast Wearing, have potential safety hazard.
Summary of the invention:For the defects that exists in the prior art, the utility model aims to provide and a kind ofly operates steadily, long service life, easy to maintenance, console model multi-rope friction hoist's head sheave device that cost is low.
To achieve these goals, the utility model is by the following technical solutions: it comprise two supports at the sky wheel shaft on the bearing seat, be fixed on fixedly head sheave and snap ring on this day wheel shaft, be located at described day wheel shaft upper between described fixedly head sheave and snap ring a plurality of floating sheaves, be fixed on the adapter shaft of day wheel shaft one end, the decoder that is fixed on the described bearing seat and is connected with this adapter shaft by coupler; Have to be located on this day wheel shaft and the axle bush sleeve of captiveing joint with floating sheave between the axis hole of floating sheave and day wheel shaft, this axle bush sleeve is involuted by the bearing shell of two semicircle tubulars.
Each floating sheave is provided with lubricating system, and this lubricating system is by the oilhole that is fixed on lubricating cup on the floating sheave, is located on this floating sheave and is communicated with gap between described axle bush sleeve and day wheel shaft, consist of the oil pipe of this oilhole and lubricating cup connection; Outer rim at fixing head sheave and each floating sheave all is fixed with plastic frame; On the sky wheel shaft, opening between that bearing seat of snap ring and right side kept off width greater than the thickness of floating sheave.
Compared with the prior art, the utility model is owing to adopted technique scheme, between floating sheave and day wheel shaft, increased the axle bush sleeve of wear-resisting and easy processing, therefore not only effectively alleviated floating sheave axis hole or day wheel shaft wearing and tearing, prolonged service life, and it is also very convenient quick to change axle bush sleeve, has overcome trouble and the high defective of maintenance cost changing floating sheave or day wheel shaft and bring.In addition, owing to be provided with lubricating system, not only avoided bearing shell to hold defective easy to wear, further prolonged the service life of bearing shell and day wheel shaft because of dry friction, but also can guarantee that the operation of floating sheave is more smooth, steady.Because the outer rim at fixing head sheave and each floating sheave is provided with plastic frame, so can either avoid steel rope to skid, improve the head sheave traveling comfort, can slow down again steel rope wearing and tearing, increase the service life.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A place enlarged drawing among Fig. 1.
Among the figure: fixing 5 days wheel shaft 6 decoders of head sheave 1 floating sheave 2 lubricating cups 3 oil pipes 4 bearing shells, 7 bearing seats, 8 snap rings, 9 bearings, 10 plastic frames, 11 adapter shafts, 12 coupler 13
The specific embodiment:The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
As shown in Figure 1, 2: the two ends of day wheel shaft 6 are bearing in respectively on two bearing seats 8 by bearing 10 separately, are fixed with fixedly head sheave 1 and snap ring 9 on day wheel shaft 6, and three floating sheaves 2 that are enclosed within on day wheel shaft 6 are fixedly being arranged between head sheave 1 and the snap ring 9.The axle bush sleeve that is located on this day wheel shaft and captives joint by screw with corresponding floating sheave 2 is arranged between the axis hole of each floating sheave 2 and day wheel shaft 6, and this axle bush sleeve is involuted by the bearing shell 5 of two semicircle tubulars.Right-hand member at sky wheel shaft 6 has the with it adapter shaft 12 of captive joint, and the decoder 7 that is fixed on the bearing seat 8 is connected with adapter shaft 12 by coupler 13; Decoder 7 can play the effect that detects steel rope slippage on fixedly head sheave 1 or the floating sheave 2.
Lubricated in order to increase, reduce friction, each floating sheave 2 is provided with lubricating system, and this lubricating system is by the oilhole that is fixed on lubricating cup 3 on the floating sheave 2, is located on this floating sheave and is communicated with gap between described axle bush sleeve and day wheel shaft 5, consist of the oil pipe 4 of this oilhole and lubricating cup 3 connections.
In order to increase friction, to avoid steel rope to skid, simultaneously also in order to slow down steel rope abrasion, all be fixed with plastic frame 11 in the fixing outer rim of head sheave 1 and each floating sheave 2.
For the ease of changing bearing shell 5, that section sky wheel shaft 6 between that bearing seat 8 of snap ring 9 and right side is optical axis, and opening of this section optical axis keeps off width greater than the thickness of floating sheave 2.During maintenance, only needing that screw is pulled down, unclamped to snap ring 9 can change the bearing shell 5 that is fixed on each floating sheave 2 one by one, easy to operate.
