Abstract

A kind of mine excavator guy wire device, comprise socket, wire rope, it is characterized in that the inner chamber of socket is inverted conical shape, wire rope one end penetrates the inner chamber of socket by the perforation small end of socket, insert oiling pipe fitting in the middle of the large end of socket, oiling pipe fitting periphery is the wire rope scattered, and the inner of oiling pipe fitting is positioned at socket and wire rope junction is inner, sealed fixing between socket inner chamber and wire rope by Babbitt Metal, the outer end of oiling pipe fitting arranges plug.The utility model due to the cavity of socket be inverted conical shape, pulling force is larger, and the combination of wire rope and babbit is more firm.Inject lubrication oil by oiling pipe fitting to socket and wire rope junction, socket and wire rope junction are lubricated fully, prevents the generation of corrosion phenomena, ensure that the demand of work, extend the application life of guy wire device.

Description

Mine excavator guy wire device

Technical field

The utility model belongs to a kind of parts of mine excavator, particularly a kind of new type mining stretching rope for excavator device with oiling pipe fitting.

Background technology

Mine excavator is a kind of main equipment of open coal mine mining, and the critical piece (see figure 1) forming excavator is made up of the socket 6 of running gear 1, undercarriage bea 2, slew gear 3, revolving dial 4, A-frame 5, guy wire device and wire rope 7, boom 8, bucket rod apparatus rod 9 and bucket body device 10 etc.

The structure of guy wire device connection is: one end of A-frame 5 is fixed on revolving dial 4, and one end and revolving dial 4 hinge of boom 8 connect, and the two ends of guy wire device connect with the other end of A-frame 5 and boom 8 respectively.

One end due to boom 8 is hinge connection, and boom 8 is another rod members, and when free state, boom 8 is around hinge through, after two ends and A-frame 5, the boom 8 of guy wire device connect, forms triangle junction and boom 8 is fixed.The length of guy wire device is different, the height that boom is propped and different from the angle on ground.When bucket rod apparatus rod 9 is reciprocating on boom 8, bucket body device 10 is driven to carry out excacation.Because the own wt of boom 8, bucket rod apparatus rod 9, bucket body device 10 just has more than 100 ton, add working resistance, the tensile force that guy wire device bears is very large, and the effect of visible guy wire device is very important.

Existing mine excavator guy wire device in use finds that its application life is very short, and the position of primary damage is the place at socket 6 and wire rope 7 client link, this place's corrosion of visual inspection very serious, lacks lubrication oil.By analysis, because socket 6 and wire rope 7 junction lack lubrication oil, easy-to-rust, makes the intensity of wire rope reduce, when bucket body device 10 works, guy wire device is subject to stretching repeatedly, bending, vibration etc., socket 6 and wire rope 7 junction easily produce that stress is concentrated, tired, when lacking lubrication oil, the wear phenomenon of wire rope 7 is serious, has occurred corrosion, fracture etc., when the steel wire ruptured reaches certain ratio, guy wire device is scrapped.Guy wire device lifetime short, fragile internal construction with it, manufacturing process is unreasonable very large relation.

Summary of the invention

The purpose of this utility model is to provide a kind of novel mine excavator guy wire device, improve original internal construction, convenience can inject lubrication oil in the wire rope centre of socket and wire rope junction during manufacture, make this place's sufficient lubrication reduce corrosion, increase the service life.

The technical solution of the utility model is as follows: comprise socket, wire rope, it is characterized in that: the inner chamber of socket is inverted conical shape, wire rope one end penetrates the inner chamber of socket by the perforation small end of socket, oiling pipe fitting is inserted in the middle of the large end of socket, oiling pipe fitting periphery is the wire rope scattered, the inner of oiling pipe fitting is positioned at socket and wire rope junction is inner, and sealed fixing between socket inner chamber and wire rope by Babbitt Metal, the outer end of oiling pipe fitting arranges plug.

Effect of the present utility model: the cavity due to socket is inverted conical shape, and pulling force is larger, the combination of wire rope and babbit is more firm.Inject lubrication oil by oiling pipe fitting to socket and wire rope junction, socket and wire rope junction are lubricated fully, prevents the generation of corrosion phenomena.Ensure that the demand of work, extend the application life of guy wire device, show according to use result, the application life of original guy wire device is generally about 0.5-2, and the guy wire device using the oiling of oiling pipe fitting instead is generally all greater than 2 years application life.

Detailed description of the invention

See Fig. 2,3, concrete structure is as follows: the inner chamber with the socket 6 of connecting ring 6-1 is inverted conical shape, wire rope 7 one end penetrates the inner chamber of socket by the perforation small end of socket, oiling pipe fitting 6-5 is inserted in the middle of the large end of socket, oiling pipe fitting 6-5 periphery is the wire rope 6-3 scattered, the inner of oiling pipe fitting 6-5 is positioned at socket and wire rope junction is inner, and pour into a mould to seal by babbit 6-4 between socket inner chamber and wire rope and fix, the outer end of oiling pipe fitting 6-5 arranges plug 6-2.

Manufacturing process is as follows: the fag end of wire rope 7 one end penetrates in socket 6, steel wire rope head is opened the every root steel wire in steel wire rope head is independently scattered, again cable wire end is put into tank, the water adding washing agent and boiling in tank carries out poach, greasy dirt between steel wire each in cable wire end is cooked (object of poach is that each steel wire between steel wire rope head and babbit are combined into one more fully), find the position between socket 6 and wire rope 7 fag end, make between socket 6 and wire rope 7 as same axis wire clamp is tight, fixing, then be placed on fixing mold, preheating is carried out to it, dry, again oiling pipe fitting 6-5 is put into the junction of socket 6 and wire rope 7, the babbit 6-4 dissolved is poured in the cavity of socket 6, babbit 6-4 is fully contacted with wire rope 7 fag end be solidified into one.

Claims

1. a mine excavator guy wire device, comprise socket, wire rope, it is characterized in that: the inner chamber of socket is inverted conical shape, wire rope one end penetrates the inner chamber of socket by the perforation small end of socket, insert oiling pipe fitting in the middle of the large end of socket, oiling pipe fitting periphery is the wire rope scattered, and the inner of oiling pipe fitting is positioned at socket and wire rope junction is inner, sealed fixing between socket inner chamber and wire rope by Babbitt Metal, the outer end of oiling pipe fitting arranges plug.
