Abstract
The utility model relates to a main pin shaft lubrication structure of a double-tine bulk-cargo grab bucket. The main pin shaft lubrication structure comprises a main pin shaft, four mutually independent oblique-line type oil channels are arranged on the main pin shaft, one end of each of the four oil channels is an oil mouth for filling oil, the other end of each of the four oil channels is an independent oil outlet, the four oil mouths for filling the oil is arranged at the end of the main pin shaft, and the central line of each oil outlet form an included angle smaller than 90 DEG with the central axis of the main pin shaft. The main pin shaft of the utility model plays a role of a rotating hinge shaft of tines, the two tines freely rotate on the shaft according to the opening and closing orders of the grab bucket to achieve the goal of grabbing and unloading the cargo by the tines. When oil channels of the main pin shaft of the tines are blocked, the oil channels can be dredged without disassembling the pin shaft, so that the maintenance becomes simple and convenient, and the production efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of grab bucket equipment of power jacking machine, especially relate to a kind of double-jaw bulk goods grab bucket stub axle lubrication system, this stub axle lubrication system can make the stub spindle oil road of double-jaw formula machinery grab bucket equipment of bulk goods such as loading and unloading coal dust, breeze smooth and easy.
Background technology
The grab bucket of machinery double-jaw formula is that harbour, power plant use comparatively general a kind of bulk handling device.Between the bucket lobe of traditional mechanical double-jaw formula grab bucket and the cross sill is by the bearing pin that has oilway the two to be coupled together.The stub axle place of large-scale ore grab bucket, normally two plain bearings are separately fixed on two bucket lobes.The endoporus of plain bearing and bucket lobe bearing pin herein exist certain clearance and relative motion.For reduce friction, smooth rotation need process oil duct usually and lubricate its sleeve inner surface on bearing pin.Oil circuit is generally two, and is provided with turning point in the centre.Because ore grab bucket service conditions is abominable, breeze be accompanied by lubricated butter through regular meeting with fuel clogging, and harden and be bonded in the exit of oil duct.If want to dredge this oil duct, must be with bearing pin dismounting cleaning.General tonnage is bigger, bearing pin heavy and grab bucket, and does not have cooresponding weight-lifting equipment just to be difficult to keep in repair.
Summary of the invention
Given this, technical problem to be solved in the utility model is in order to overcome stifled, the defective of easy to clean maintenance not in the lubricating oil Louis that exists in the prior art, and a kind of double-jaw bulk goods grab bucket bearing pin lubrication system is provided, this bearing pin lubrication system can make channel for oiling unimpeded.
For solving the problems of the technologies described above, the technical solution of the utility model is to realize like this, a kind of double-jaw bulk goods grab bucket stub axle lubrication system, comprise lubricated stub axle, it is characterized in that: on the stub axle, be provided with four separate bias type oil ducts, one end of these four oil ducts is four gas filed oil nozzles, the other end is four independently oil outlets, described four gas filed oil nozzles are arranged on the end of stub axle, and the line of centers of each oil outlet becomes an angle less than 90 degree with the central axis of stub axle.
Described oil outlet is distributed on the same face of cylinder.
The beneficial effects of the utility model, the utility model changes existing two oil circuits into four path and the oblique layouts of oil duct independent, that each does not communicate, does not have turning point.This kind structure, breeze is if get lodged in the oil duct junction place again, only need a cooresponding iron wire of diameter or drill bit just oil duct can be dredged, can not get lodged in the problem of not dredging in the oil circuit of turning because of breeze or dust, the more important thing is the service life that can prolong bearing pin and lining, thereby alleviated client's maintenance load, reduced productive costs.
Description of drawings
Fig. 1 is the utility model stub axle and lining bonded assembly structural representation.
Fig. 2 is the utility model stub axle construction scheme drawing.
Fig. 3 is the structural representation of the utility model stub axle other direction.
Fig. 4 is the sectional structure scheme drawing of the utility model stub axle.
The specific embodiment
Below in conjunction with accompanying drawing, structure of the present utility model is made a concrete analysis of.A kind of double-jaw bulk goods grab bucket of the utility model stub axle lubrication system comprises lubricated stub axle 1, and this stub axle 1 is joined with lining 2, referring to shown in Figure 1.Be combined in stub axle 1 and be provided with four separate bias type oil ducts 2.One end of these four bias type oil ducts 3 is four gas filed oil nozzles 4, the other end is four independently oil outlets, described four gas filed oil nozzles 4 are arranged on the end 5 of stub axle, with convenient oily to the stub axle, oil outlet is distributed on the same face of cylinder, and the line of centers X of each four bias type oil duct 3 becomes an angle less than 90 degree with the central axis Y of stub axle 1.Referring to Fig. 2, Fig. 3 and shown in Figure 4.
Stub axle in the utility model is taken on the role of bucket lobe swing hinge axis, and two bucket lobes turn round freely on axle with the switching order of grab bucket, reaches the purpose of the extracting of bucket lobe, unloading.This bucket lobe stub axle can not dismantled the stub axle when oil circuit takes place to stop up, just oil circuit can be dredged, and makes maintenance become simple, convenient, has improved production efficiency widely.
Claims (2)
1. double-jaw bulk goods grab bucket stub axle lubrication system, comprise lubricated stub axle, it is characterized in that: on the stub axle, be provided with four separate bias type oil ducts, one end of these four bias type oil ducts is four gas filed oil nozzles, the other end is four independently oil outlets, described four gas filed oil nozzles are arranged on the end of stub axle, and the line of centers of each bias type oil duct becomes an angle less than 90 degree with the central axis of stub axle.
2. a kind of double-jaw bulk goods grab bucket stub axle lubrication system according to claim 1, it is characterized in that: described oil outlet is distributed on the same face of cylinder.
