Detailed Description

The following detailed description of the embodiments of the present invention will be given in conjunction with the accompanying drawings to make it clear to those skilled in the art how to practice the present invention. While the utility model has been described in connection with preferred embodiments thereof, these embodiments are merely illustrative, and not restrictive, of the scope of the utility model.

In the description of the technical solution of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which are only for convenience of describing the present patent and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the description of the technical solutions of the present invention, it should be further noted that, unless explicitly stated or limited otherwise, the terms "disposed," "mounted," "connected," and "connected" should be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. Specific meanings of the above terms in the technical solutions of the present invention can be understood by those of ordinary skill in the art according to specific situations.

Referring to fig. 1 and 2, the lubricating device for the oil storage tank between the stay bar and the bucket flap of the grab bucket comprises a stay bar 1, a bucket flap 2, a shaft sleeve 3, a pin shaft 4, a bearing bush 5, an oil storage tank 6, an oil passage 7 and an oil injection nozzle 8.

The lower extreme of vaulting pole 1 is fixed with axle sleeve 3, and the middle part of fill lamella 2 is fixed with round pin axle 4, and round pin axle 4 sets up in axle sleeve 3 to be equipped with axle bush 5 between the two.

The difference with prior art lies in that, the lower extreme of vaulting pole 1 is equipped with batch oil tank 6, and batch oil tank 6 links up with the surface of axle sleeve 3, has seted up oil duct 7 on the axle sleeve 3, and oil duct 7 communicates the inboard space of axle sleeve 3 and batch oil tank 6 in the outside, and the top or the side of batch oil tank 6 are equipped with oiling mouth 8.

Wherein, the shaft sleeve 3 is generally made of a steel sleeve.

The oil reservoir 6 may be a cavity structure formed at the lower end of the stay 1, or may be a separate member mounted to the lower end of the stay 1.

Lubricating oil under the action of gravity, both can flow to the inboard space of axle sleeve 3 from batch oil tank 6 through oil duct 7, also can flow to batch oil tank 6 from the inboard space of axle sleeve 3 through oil duct 7, and the flow direction is two-way, and then realizes two-way lubrication on round pin axle 4.

When the grab bucket works, along with the actions of the stay bar 1 and the bucket flap 2, lubricating oil under the action of gravity flows among the oil storage tank 6, the oil duct 7, the pin shaft 4 and the bearing bush 5, so that the lubrication between the pin shaft 4 and the bearing bush 5 can be effectively and timely realized, the operation of the hinged part between the stay bar 1 and the bucket flap 2 is ensured to be reliable and stable, and the grab bucket is ensured to operate in a good state all the time.

It should be noted that many variations and modifications of the embodiments of the present invention fully described are possible and are not to be considered as limited to the specific examples of the above embodiments. The above examples are given by way of illustration of the utility model and are not intended to limit the utility model. In conclusion, the scope of the present invention should include those changes or substitutions and modifications which are obvious to those of ordinary skill in the art.
