Abstract
The utility model discloses a conveniently-disassembled/assembled hinge pin of a quick-change connector of an excavator. The hinge pin is characterized in that a bucket rod of the excavator is connected with a bucket through a quick-change device; a quick-change connector is connected with the bucket through a hinge pin; one end of the hinge pin is provided with a hole in which bolt is mounted; and the other end of the hinge pin is provided with an arc groove step. The hinge pin through which the quick-change connector is connected with the bucket has the following beneficial effect: the bolt is disassembled first, and the special arc groove step of the hinge pin is directly held by a hand to pull out the hinge pin without using a special disassembly/assembly tool, thereby realizing disassembly and change of the quick-change connector and the bucket; and the assembly steps are opposite to the disassembly steps.
Description
Technical field
The utility model relates to a kind of quickly dismantled bearing pin that is used for the hydraulic crawler excavator hydraulic quick coupler.
Background technology
The scraper bowl that is connected with hydraulic quick coupler on the excavator need often change; Therefore the frequent dismounting of bearing pin needs that is connected with scraper bowl of hydraulic quick coupler; The special-purpose step that this type of general bearing pin does not clutch; Dismounting must be used instrument and realized, under the situation that does not have special-purpose dismantling device, is difficult to dismounting like this.
Summary of the invention
The utility model problem to be solved is: excavator hydraulic quick coupler and scraper bowl are when dismounting; Pull down bolt earlier; Under the situation of tearing the pin instrument open that need not be special-purpose, because bearing pin has a special arc groove step, can be directly with the special step of holding bearing pin in hand; Easily extract bearing pin, thus the taking apart of convenient realization hydraulic quick coupler and scraper bowl; Installation steps are pressed demounting procedure and are driven in the wrong direction.For the excavator hydraulic quick coupler provides a kind of portable bearing pin that can directly realize dismounting with hand.
The technical solution of the utility model is such: a kind of dismounting portable bearing pin of excavator hydraulic quick coupler; Comprise scraper bowl, hydraulic quick coupler, bearing pin, dipper, bolt, step; It is characterized in that dipper passes through hydraulic quick coupler and is connected with scraper bowl, be connected through bearing pin between hydraulic quick coupler and the scraper bowl.
The porose erection bolt of bearing pin one end, the other end has step.
The utility model has the advantages that: overcome the limitation that traditional dismounting mode must be used removal tool special, realized the convenient dismounting that is connected bearing pin of hydraulic quick coupler and scraper bowl, and made easy and simple to handleization; Simple in structure; With low cost, effect is obvious, and applicability is good.
Description of drawings
It is such that the structure of the utility model constitutes:
Fig. 1 is the front view of the utility model.
Fig. 2 be the utility model by B-B sectional view among Fig. 1.
Among Fig. 1～Fig. 2, scraper bowl (1), hydraulic quick coupler (2), bearing pin (3), dipper (4), bolt (5), step (6).
The specific embodiment
The most preferred embodiment of the utility model is such; With reference to Fig. 1～Fig. 2; The dipper of excavator (4) is connected with scraper bowl (1) through hydraulic quick coupler (2), flexibly connects the bearing pin porose erection bolts of (3) one ends (5) between hydraulic quick coupler (2) and the scraper bowl (1) through bearing pin (3); The other end is step (6), and step (6) is made the circular arc flute profile.When changing scraper bowl (1), pull down bolt (5) earlier, can not use under the special-purpose situation of tearing the pin instrument open, directly, easily realize the dismounting of bearing pin (3) with arc groove step bearing pin (3) right-hand member as shown in Figure 2 of holding bearing pin (3) in hand; Installation steps are pressed demounting procedure and are driven in the wrong direction.
Claims (2)
1. the dismounting portable bearing pin of an excavator hydraulic quick coupler; Comprise scraper bowl, hydraulic quick coupler, bearing pin, dipper, bolt, step; It is characterized in that dipper (4) is connected with scraper bowl (1) through hydraulic quick coupler (2), be connected through bearing pin (3) between hydraulic quick coupler (2) and the scraper bowl (1).
2. according to the dismounting portable bearing pin of the described a kind of excavator hydraulic quick coupler of claim 1, it is characterized in that the bearing pin porose erection bolts of (3) one ends (5), the other end has step (6).
