The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
It should be noted that, in the situation that do not conflict, embodiment and the feature in embodiment in the utility model can combine mutually.
Basic thought of the present utility model is: design a kind of excavator assembly type thumbscrew, be arranged on excavator, for solving traditional excavator, be difficult to situation about capturing or shovel is got specific material, the expansion digging machine scope of application.
Below in conjunction with accompanying drawing, each preferred embodiment of the present utility model is described further:
As shown in Fig. 1-4, a kind of excavator assembly type thumbscrew, be applied on excavator, excavator comprises dipper 5, rocking bar 6 and scraper bowl 7, and scraper bowl 7 is articulated in the front end of dipper 5, and rocking bar 6 connects dipper 5 and scraper bowl 7, rocking bar 6 comprises with dipper 5 and being connected, for the support bar part of supporting crank 6; It is characterized in that, excavator assembly type thumbscrew comprises spacing connecting rod 4, bearing 3, stretching device 2 and thumbscrew 1;
The operating principle of technique scheme is: by thumbscrew 1 is set on excavator, and thumbscrew 1 is fixed on the dipper 5 of excavator, make when crawl or shovel while getting elongated rod shape or the block object of large volume, thumbscrew 1 will coordinate with scraper bowl 7, jointly this object is captured, or thumbscrew 1 coordinates scraper bowl 7 by object scraper bowl 7; Thumbscrew 1 is controlled and is moved back and forth by a stretching device 2, and the other end of stretching device 2 is supported by support 3, and stretching device 2 is fixed between thumbscrew 1 and bearing 3, makes stretching device 2 to work; Bearing 3 also is connected with spacing connecting rod 4, the two ends of spacing connecting rod 4 are dipper 5 and the bearing 3 of connecting excavator respectively, for limiting the movement of bearing 3, also for the position that bearing 3 is positioned on dipper 5, adjusted simultaneously, and then the movement locus of change thumbscrew 1, to meet needs and the adaptation under different operating modes of scraper bowl 7 and thumbscrew 1, on the digger operating device of different size, install.
On the basis of technique scheme, further, several through holes 10 are set in line on spacing connecting rod 4, and at the some projections 9 that coordinate with through hole 10 sizes of the sidewall arranged outside of the notch 8 of bearing 3, bearing 3 is connected with the detachable of spacing connecting rod 4 by projection 9 realizations; Projection 9 is fixedly connected with by bolt 18 with spacing connecting rod 4, and bolt 18 runs through projection 9 along the length direction perpendicular to spacing connecting rod 4, and bolt 18 also contacts with spacing connecting rod 4 outer surfaces; In the left and right sides of bearing 3, two projections 9 are set respectively; Wherein, on spacing connecting rod 4, through hole 10 is set, the projection 9 coordinated with through hole 10 is set on bearing 3, projection 9 is connected with spacing connecting rod 4 and makes 4 pairs of bearings 3 of spacing connecting rod limit along moving on the length direction of spacing connecting rod 4 by through hole 10; A plurality of through holes 10 are set simultaneously makes bearing 3 can be positioned different position on the dipper 5 of excavator, and then the movement locus of change thumbscrew 1, to meet needs and the adaptation under different operating modes of scraper bowl 7 and thumbscrew 1, on the digger operating device of different size, install.
Concrete, when stretching device 2 when carrying out stretching motion, stretching device 2 constantly changes with the angle of spacing connecting rod 4, and therefore, the power that stretching device 2 acts on bearing 3 will form to bearing 3 action moment constantly changed along with stretching device 2 and the angle of the continuous variation of spacing connecting rod 4; Now in the left and right sides of bearing 3, two projections 9 are set respectively, when bearing 3 has deflection trend, the through hole 10 of spacing connecting rod 3 will apply rightabout power to two projections 9 respectively, the size of power is synchronizeed with the variation of aforementioned moment of flexure, and then 2 pairs of bearings 3 of counteracting stretching device apply, the moment of flexure that bearing 3 is deflected, make bearing 3 be unlikely to deflect.
On the basis of technique scheme, further, be respectively arranged with friction pad 15, pressing plate 11 and boss 12 between the both sides of notch 8 cell wall and dipper 5, pressing plate 11 is realized detachable the connection with the sidewall of the notch 8 of bearing 3 by securing member 17, friction pad 15 has two, be arranged at respectively between pressing plate 11 and dipper 5 and between boss 12 and dipper 5, for stoping bracket component and dipper 5 relative slidings; On a side channel wall of notch 8, a boss 12 is set, opposite side is installed pressing plate 11, form groove 13 between the bottom land of boss 12 and pressing plate 11 and notch 8, on dipper 5 with the position that is complementary of groove 13 be provided with corresponding protruding 14, between groove 13 and projection 14 mutually coupling overcome bearing 3 and break away from dippers 5 to assist; Bottom land setting at described notch 8 contacts with described dipper 5, and for slowing down described bearing 3 and described dipper 5 phase impact, the bottom friction pad 16 of uniform contact; Wherein, by securing member 17 connection pressing plates 11 and bearing 3, make pressing plate 11 relative with bearing 3 fixing, tightening fastener parts 17 is with the active force of the dipper 5 of 11 pairs of excavators of raising pressing plate simultaneously, and by being set on pressing plate 11, friction pad 15 make support 8 relative with dipper 5 fixing, for retraining bearing 3 or stretching device 2 because deadweight breaks away from the mobile trend of dipper 5, and then bearing 3 is fixed on dipper 5; Boss 12 is set respectively on the cell wall of the both sides of notch 8 and pressing plate 11 is installed, form groove 13 between the bottom land of boss 12 and pressing plate 11 and notch 8, be provided with corresponding protruding 14 with the position that is complementary of groove 13 on dipper 5, coupling mutually between groove 13 and projection 14, for stoping when the significantly skew of bearing 3 due to deadweight or unexpected stressed generation while making pressing plate 11 not to be fixed on dipper 5 by bearing 3;
Concrete, when thumbscrew 1, when clamping weight, stretching device 2 stretches out, and then bearing 3 is produced to thrust, the bottom land of the notch 8 on bearing 3 contacts with dipper 5 by bottom friction pad 16, has slowed down the impact of bearing 3 relative dippers 5, and the support force perpendicular to dipper 5 bottom surfaces is provided; Bearing 3 is connected with the through hole 10 of spacing connecting rod 4, the other end of spacing connecting rod 4 is hinged on the rocker shaft hole site of dipper 5, bearing 3 is provided and is parallel to dipper 5 bottom surfaces, along the pulling force of spacing length of connecting rod direction, thereby stop thumbscrew assembly bearing 3 when work to produce situation about moving relative to dipper 5.
