Abstract
The utility model discloses a moving head sheave device for a mining lifting winch and belongs to parts of the mining lifting winch. The moving head sheave device is stable in operation, long in service life, convenient to maintain and low in cost and comprises a head sheave shaft with two ends supported on a bearing seat and two retaining rings fixed on the head sheave shaft and a head sheave arranged on the head sheave shaft and positioned between the two retaining rings, and shaft bushes (2) sleeved on the head sheave shaft and fixedly connected with the head sheave are arranged between a shaft hole of the head sheave (1) and the head sheave shaft (5). Abrasion between the shaft hole of the head sheave or the head sheave shaft is effectively reduced, the service life is prolonged, defects of troubles caused by replacement of the head sheave or the head sheave shaft and high maintenance cost are overcome, and the moving head sheave device for the mining lifting winch is an improved structure.
Description
Technical field
The utility model relates to a kind of mine hoist, relates in particular to a kind of mine hoist floating sheave device.
Background technology:The mine hoist floating sheave claims again rope sheave; Be arranged on the guiding fixed pulley that derrick or staple shaft top are used for support and hoisting cable; Be mainly used in carrying the weight of cage, well-bucket or vertical shaft skip.
At present, the floating sheave of mine hoist adopts the mode that directly cooperates with day wheel shaft to be installed on day wheel shaft usually.Because its size of wheel is large, processing difficulty relatively, so axis hole roughness of surface and hardness are lower, have that quick abrasion, service life are short, maintenance trouble and a high in cost of production defective.In addition, because lubricating system is not set, not only the flatness of head sheave operation is relatively poor, and has further aggravated the wearing and tearing of head sheave or day wheel shaft.
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, mine hoist floating 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 two back-up rings on this day wheel shaft, be located at the upper head sheave between described two back-up rings of this day wheel shaft; Having between the axis hole of head sheave and day wheel shaft is enclosed within on this day wheel shaft and the bearing shell of captiveing joint with described head sheave.
Bearing shell is two, is fixed in the described axis hole from the two ends of head sheave respectively; The lubricating cup that is fixed on the head sheave is communicated with by being located at oilhole and bearing shell on the head sheave and the gap between day wheel shaft.
Compared with the prior art, the utility model is owing to adopted technique scheme, between head sheave and day wheel shaft, increased the bearing shell of wear-resisting and easy processing, therefore not only effectively alleviated day axle hole or day wheel shaft wearing and tearing, prolonged service life, and bearing shell changes also very convenient fast, overcome trouble and the high defective of maintenance cost changing head sheave or day wheel shaft and bring.In addition, because can be to the lubricating cup of bearing shell and day wheel shaft injection lubricating oil head sheave being provided with, not only avoided the defective of the easy wearing and tearing of dry friction, further prolonged the service life of bearing shell and sky wheel shaft, but also can guarantee that the head sheave operation is more smooth, steady.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Among the figure: 4 days wheel shaft 5 bearings of head sheave 1 bearing shell 2 bearing seats, 3 back-up rings, 6 lubricating cups 7
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: the two ends of day wheel shaft 5 are bearing in respectively on two bearing seats 3 by a bearing 6 separately, and two back-up rings 4 are fixed by screws in respectively on day wheel shaft 5; The axis hole two ends of head sheave 1 are provided with this shaft hole matching and are fixed by screws in respectively two bearing shells 2 on the head sheave 1, and head sheave 1 is located on that section sky wheel shaft 5 between two back-up rings 4 by bearing shell 2.
In order to alleviate friction, guarantee head sheave 1 operate steadily, smooth, be fixed with lubricating cup 7 in head sheave 1, this lubricating cup is communicated with gap between bearing shell 2 and the sky wheel shaft 5 by the oilhole that is located on the head sheave 1.
Claims (3)
1. mine hoist floating sheave device, comprise two supports at the sky wheel shaft on the bearing seat, be fixed on two back-up rings on this day wheel shaft, be located at the upper head sheave between described two back-up rings of this day wheel shaft; It is characterized in that: between the axis hole of head sheave (1) and day wheel shaft (5), the bearing shell (2) that is enclosed within on this day wheel shaft and captives joint with described head sheave is arranged.
2. mine hoist floating sheave device according to claim 1, it is characterized in that: bearing shell (2) is two, is fixed in the described axis hole from the two ends of head sheave (1) respectively.
3. mine hoist floating sheave device according to claim 1 and 2 is characterized in that: the lubricating cup (7) that is fixed on the head sheave (1) is communicated with gap between bearing shell (2) and day wheel shaft (5) by the oilhole that is located on the head sheave (1).
