Abstract
The utility model discloses a grab bucket pulley block coupling pin with a highly antiwear structure. The grab bucket pulley block coupling pin comprises a connecting pin and a positioning pin, wherein a fixing hole is formed in the connecting pin, the positioning pin is matched with the fixing hole, and a liner bushing is arranged on the connecting pin in a position next to a connecting pin seat. The grab bucket pulley block coupling pin with the highly antiwear structure is characterized in that the structure of the liner busing and a flow guide hole is arranged on the connecting pin, in use, a lubricating oil is added to a flow guide groove of the linear bushing via the flow guide hole, and therefore, the excellent lubrication effect is achieved and the working friction is reduced so that the abrasion of the connecting pin is greatly reduced, in addition, the replacement of a grab bucket is changed into the replacement of the liner bushing, and as a result, the maintenance time is reduced and the maintenance expenditure is saved, and both cost and workload are greatly reduced. As long as the grab bucket pulley block coupling pin with the highly antiwear structure is used, the stationarity of the grab bucket in the working process is greatly improved, and potential safety hazards during ore loading are reduced. The grab bucket pulley block coupling pin with the highly antiwear structure is simple in structure, low in implementation cost, and stable and reliable in working, and is an ideal apparatus for industrial and mining enterprises.
Description
Technical field
The utility model belongs to engineering mechanical device technical field, is specifically related to a kind of simple in structurely, has the grab bucket pulley group coupled axle-pin of high wear-resistant structure.
Background technique
In the working procedure of dress ore deposit, mine, grab bucket working efficiency in the time of dress ore deposit is high, saves time, and in the time that grab bucket needs repairing because damage, need to arrange loader to fill ore deposit, not only the rate of loading is slow, and expend a large amount of diesel oil, therefore grab bucket plays irreplaceable effect.While breaking down in grab claw running, as easy as rolling off a log falling pounded lorry or staff, causes work pause or staff's injury, has great potential safety hazard; After grab bucket goes wrong, must change grab bucket again, not only expend time in many, and increased maintainer's labor intensity; Whole grab bucket is changed rather than trouble unit is changed, wasted and can utilize parts, increased operating cost.By to the investigation that damages grab bucket, to be pin and pin-and-hole cause that grab bucket work is not steady because of working deformation to the main damage parts of finding grab bucket.Therefore, in order enhancing productivity, to reduce input cost, to reduce intensity of workers and potential safety hazard, the problem occurring for grab bucket, develops a kind of scheme that solves existing issue, pin is improved to meet need of production and be very important.
Model utility content
The purpose of this utility model is to provide a kind of simple in structure, replacing convenience, has the grab bucket pulley group coupled axle-pin of high wear-resistant structure.
The purpose of this utility model is achieved in that and comprises and attachment pegs and locating stud, in described attachment pegs, fixed hole is set, and described locating stud matches with fixed hole, in described attachment pegs, near the position of attachment pegs seat, lining is set.
The utility model by arranging the structure of lining and pod apertures in attachment pegs, lubricant oil IMU is crossed in the guiding gutter that pod apertures is added to lining, play good lubrication effect, reduce work friction, the wearing and tearing of attachment pegs are reduced greatly, replacing to grab bucket becomes the replacing to lining, reduces the repair time and saves recondition expense, and cost and workload all reduce greatly.The utility model has improved grab bucket stationarity in the course of the work greatly after using, the potential safety hazard while having reduced dress ore deposit.The utility model is simple in structure, and implementation cost is cheap, and working stability is reliable, has effectively improved grab bucket work condition state, has reduced cost of production, increases work efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is the utility model lining schematic top plan view;
Fig. 3 is that the A-A of Fig. 2 is to view;
In figure: 1-attachment pegs, 11-connects key seat, 2-lining, 21-guiding gutter, 3-pod apertures, 4-locating stud.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but never in any form the utility model is limited, based on any change of the present utility model or improvement, all belong to protection domain of the present utility model.
As shown in accompanying drawing 1 ~ 3, the utility model comprises attachment pegs 1 and locating stud 4, in described attachment pegs 1, fixed hole is set, and described locating stud 4 matches with fixed hole, in described attachment pegs 1, near the position of attachment pegs seat 11, lining 2 is set.
On described connection key seat 11, pod apertures 3 is set, described pod apertures 3 is led to lining 2.
Described lining 2 arranges guiding gutter 21, and described guiding gutter 21 coordinates with pod apertures 3 work.
Described guiding gutter 21 is arranged at lining 2 internal surface middle parts.
Described lining 2 is made for high-abrasive material.
The import of described pod apertures 3 is arranged at and connects key seat 11 shaft core positions.
The thickness of described lining 2 is 1 ~ 3cm.
Described guiding gutter 21 width and the diameter of pod apertures 3 adapt.
Working principle of the present utility model and working procedure:
The utility model is taked, at the eroded area of concrete component, lining is set and is reduced the principle to its wearing and tearing, by the structure of lining and pod apertures is set in attachment pegs, in use lubricant oil is added to by pod apertures in the guiding gutter of lining, play good lubrication effect, reduce work friction, the wearing and tearing of attachment pegs are reduced greatly, the replacing of grab bucket has been become to the replacing to lining, reduce the repair time and save recondition expense, cost and workload all reduce greatly.The utility model has improved grab bucket stationarity in the course of the work greatly after using, the potential safety hazard while having reduced dress ore deposit.The utility model is simple in structure, and implementation cost is cheap, and working stability is reliable, is the ideal equipment of industrial and mining enterprise.
In the time that grab bucket work is not steady or break down, check whether be that the wearing and tearing of grab bucket pulley group coupling arrangement or distortion cause, if so, by taking out positioning pin, wearing and tearing lining is changed with new lining, then locating stud is loaded onto.
