Abstract

The utility model discloses a grease bucket fixing device of a mini-excavator. The grease bucket fixing device of the mini-excavator comprises a bend pipe and a fixing plate, wherein the bend pipe is formed by a steel pipe through a plurality of times of bending, an upper portion opening of the bend pipe is in a round shape, the lower portion of the bend pipe is bended up to form a circular arc structure, protrusions are arranged outwards on portions where the fixing plate contact the steel pipe of the fixing plate, and a bolt hole is formed between two protrusions. The grease bucket fixing device of the mini-excavator has the advantages that the circular arc structure located on the lower portion of the bend pipe is capable of limiting left-right migration of the grease bucket, due to the fact that the diameter of the upper portion opening of the bend pipe is slightly smaller than the diameter of the grease bucket, the grease bucket is tightened by the bend pipe and the up-down motion of the grease bucket is limited, and the bend pipe is fixed on a revolving platform of the excavator through bolts by the fixing plate, so that wobble of the grease bucket in a working state is effectively prevented.

Description

The grease bucket fastening devices of mini-excavator

Technical field

The utility model relates to a kind of fastening devices for the mini-excavator grease bucket, belongs to excavator component technology field.

Background technology

Butter plays a very important role in the excavator operational maintenance is safeguarded, especially the bearing pin junction of each parts of digger operating device, because working strength is large, number of revolutions is many repeatedly, so the quality of lubricant effect is on there being direct impact its application life.Therefore usually work and will carry out butter filler after a period of time in equipment bearing pin junction, to guarantee its normal use.Frequent due to the butter access times, therefore usually leave the space of placing grease bucket during Excavator Design, medium-and-large-sized excavator is because volume is larger, placing the position of grease bucket better selects, and mini-excavator is little due to volume, each component characteristics of compact layout, thus how with the grease bucket fixed placement in the excavator outside.Be fixed on revolving platform of excavator after fixedly parts have been welded in the many employings of the device of grease bucket at present, as shown in Figure 1, although this device can be placed grease bucket wherein, effectively it does not fixed.Excavator has when work and rocks, and especially in the situation that use destroyer or operating mode are abominable, it is very violent that placement grease bucket wherein rocks.And it adopts welded construction, and not only manufacturing cost is high, and processes loaded down with trivial details.

The utility model content

For the problem that above-mentioned prior art exists, the utility model provides a kind of grease bucket fastening devices of mini-excavator, this device effectively fixed placement in grease bucket wherein.

To achieve these goals, the technical solution adopted in the utility model is: a kind of grease bucket fastening devices of mini-excavator, comprise bending tube and fixed head, described bending tube is repeatedly formed after bending by a steel pipe, the upper opening of bending tube is round shape, the bottom of bending tube bends up an arc structure, and described fixed head to peripheral hardware one projection, arranges a bolt hole at the position that contacts with steel pipe between two projections.

Further, the diameter of the upper opening of bending tube is less than the diameter of grease bucket.

Further, on fixed head, the middle part of two projections arranges a bolt hole.

Beneficial effect is: on the bending tube in the utility model and fixed head the processing of two projections all very simple, need low cost of manufacture, the upper opening of bending tube is neglected greatly the top size of grease bucket and is decided, when the size of grease bucket changes, as long as change a bending tube just can, be easy to replacing.The arc structure that bending tube bottom in the utility model bends up is limiting grease bucket left and right skew, be slightly less than the diameter of grease bucket due to the diameter of bending tube upper opening, its fastening grease bucket limits it and moves up and down, and fixed head is fixed in bending tube on revolving platform of excavator by bolt, effectively prevented rocking under grease bucket in working order.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As Fig. 2, as Fig. 3 and as shown in Figure 4, the utility model comprises bending tube 2 and fixed head 5, bending tube 2 is repeatedly formed after bending by a steel pipe, top 3 openings of bending tube 2 are round shape, the bottom 4 of bending tube 2 bends up an arc structure 9, fixed head 5 to peripheral hardware one projection 6, arranges a bolt hole 7 at the position that contacts with steel pipe between two projections 6, fixed head 5 is fixed in bending tube 2 on revolving platform of excavator by bolt.

The arc structure 9 that bending tube 2 bottoms 4 in the utility model bend up is limiting grease bucket 8 left and right skews, be slightly less than the diameter of grease bucket 8 due to the diameter of bending tube 2 top 3 openings, its fastening grease bucket 8 limits it and moves up and down, and fixed head 5 is fixed in bending tube 2 on revolving platform of excavator by bolt, effectively prevented rocking under grease bucket 8 in working order.

As shown in Figure 3, on fixed head 5, two projections 6 and the effect of bolt are fixing bending tubes 2, place bolt in the middle part, can strengthen further this fixation, and the while is due in the centre position, both sides stress balance, and bolt is not easy to wear.

As shown in Figure 5, top 3 openings by bending tube 2 during use are put into grease bucket 8 or take out, and whole grease bucket fastening devices is fixed on revolving platform of excavator by connecting bolt.
