Abstract
The invention relates to a hinge pin for a full-bushing full-slewing drilling machine. The hinge pin comprises a flange plate and a shaft body fixedly connected with the flange plate, wherein the shaft body is internally provided with a plurality of lubrication holes which are communicated with each other. According to the hinge pin for the full-bushing full-slewing drilling machine, a lubricant is added into the shaft body by utilizing grease nozzles through the lubrication holes in the shaft body, so that the aim of lubricating the hinge pin can be achieved.
Description
Technical field
The present invention relates to a kind of bearing pin, be specifically related to the full-sleeve full-rotation drill bearing pin.
Background technique
Continuous quickening along with China's infrastructure, construction under the various complicated geological environments such as plateau, mountain area, hills, seabeach, rivers,lakes and seas beach is more and more, often run into the underground drift sand that has during site operation, the various complicated geological situations such as solution cavity, rock stratum, traditional excavation facility and method of construction are difficult to construction.Having occurred in recent years full-sleeve full-rotation drill both at home and abroad, is a kind of Novel pile worker engineering machinery, but the bearing pin that is connected with oil cylinder on the machine, lubricating system falls behind, the working life of seriously having reduced bearing pin.
When the bearing pin of prior art was constructed in the high strength situation, this defective that seems was particularly outstanding.Therefore, design a kind of rational in infrastructurely, the simple and practical bearing pin of lubricating system is imperative.
Summary of the invention
The purpose of this invention is to provide a kind of full-sleeve full-rotation drill bearing pin, in order to solve the defective of above-mentioned prior art.
For reaching above-mentioned technique effect, the technical solution used in the present invention is: a kind of full-sleeve full-rotation drill bearing pin comprises flange plate and the axis body that is fixedly connected with described flange plate; The lubrication hole that has many places mutually to run through in the described axis body.
Thereby the present invention utilizes the many places lubrication hole in the axis body to use grease nipple to add the purpose that lubricator reaches lubricating pin shaft in axle.
Because adopt technique scheme, technique effect of the present invention has:
1, lubrication effect is obvious, uses lubricating tool can lubricate to bearing pin rapidly by grease nipple.
2, lubricating system is convenient, only needs lubricating tool and lubricator just can lubricate to bearing pin.
3, bearing pin is changed easily, because can in time lubricate, can not cause because the time is long the dismounting difficult problem between bearing pin and its fastening.
4, grease nipple is changed easily, is convenient to change at any time.
In sum, full-sleeve full-rotation drill bearing pin of the present invention has rational in infrastructurely, and lubricating structure is simple, uses reliably, and it is convenient to change, high working efficiency.This bearing pin has solved the large problem in the actual production, brings great convenience to the user.
Description of drawings
Fig. 1 is full-sleeve full-rotation drill of the present invention bearing pin side sectional view;
Fig. 2 is full-sleeve full-rotation drill of the present invention bearing pin front view.
Embodiment
A kind of full-sleeve full-rotation drill comprises flange plate 1 with bearing pin, axis body 2, and lubrication hole (3,4),, grease nipple 5.Described flange plate 1 and axis body 2 welding, then be connected with oil cylinder by the hole on the flange plate 1, lubrication hole 3 and lubrication hole 4 run through mutually, and lubricating tool adds lubricator by grease nipple 5 in axle, lubricator arrives axle 2 surfaces by lubrication hole 3 and lubrication hole 4, thereby lubricates axle 2 and be connected oil cylinder.
In order further to improve lubrication effect, the quantity of lubrication hole can be two, three or a plurality of.When lubrication hole was two, two lubrication holes were symmetricly set on the axis body.When lubrication hole was three, three lubrication holes can be positioned on the same circumferential surface, and evenly distributed, and adjacent lubrication hole is 120 degree with respect to the angle of axis body.Certainly, three angles are the lubrication holes of 120 degree, also can mutually stagger on the axis body axial direction and not on same circumference.
The above; be better case study on implementation of the present invention; be not that the present invention is imposed any restrictions, every any simple modification, change and equivalent structure of above embodiment being done according to the technology of the present invention essence changes, and all still belongs in the protection domain of technical solution of the present invention.
