Abstract
The utility model is a kind of scraper dump ram bar protection mechanism, comprises the rear hinged-support that is arranged on oil cylinder seat front end upside and the front hinged-support that is arranged on connecting rod upside; Rear rotating shaft is installed on rear hinged-support, on front hinged-support, front rotary shaft is installed; Also comprise that rear steel plate and front end that rear end is arranged in rear rotating shaft are arranged on the front spring on front rotary shaft, the front end of rear steel plate and the rear end of front spring are connected to each other by center hinge spindle.Be articulated form installation as the front spring of protection apron and the front end and back end of rear steel plate, do not affect the flexible of its below oil cylinder bar.The ore dropping out from scraper bowl drop on front spring and the upper surface of steel plate, and both sides shunting to the left and right falls earthward.Thereby effectively protect oil cylinder bar, improved the working life of Hydraulic System of LHD Unit.
Description
Technical field
The utility model relates to a kind of scraper dump ram bar protection mechanism.
Background technique
The dump ram system of scraper is mainly used in driving scraper bowl work, the upset of having stretched scraper bowl by its cylinder rod.In use, scraper bowl is carried on needing, to load more ores.In this process, ore is easy to drop from scraper bowl, injures oil cylinder bar by a crashing object.After cylinder bar is pounded, cut is pounded out on bright and clean surface, in reciprocating process, very easily damages the Sealings such as seal ring, back-up ring, dust ring, when serious, causes oil cylinder leakage of oil, affects oil cylinder working life.
model utility content
Technical problem to be solved in the utility model is, a kind of scraper dump ram bar protection mechanism is provided, and prevents that the ore dropping from scraper bowl from injuring oil cylinder bar by a crashing object.
The technical solution adopted in the utility model is as follows:
A kind of scraper dump ram bar protection mechanism, it comprises oil cylinder seat, oil cylinder seat is connected with connecting rod by its oil cylinder bar, it is characterized in that: also comprise the rear hinged-support that is arranged on oil cylinder seat front end upside and the front hinged-support that is arranged on connecting rod upside; Rear rotating shaft is installed on rear hinged-support, on front hinged-support, front rotary shaft is installed; Also comprise that rear steel plate and front end that rear end is arranged in rear rotating shaft are arranged on the front spring on front rotary shaft, the front end of rear steel plate and the rear end of front spring are connected to each other by center hinge spindle; Upper surface at front spring and rear steel plate has been bolted respectively one deck rubber pad.
Good effect of the present utility model is:
Be articulated form installation as the front spring of protection apron and the front end and back end of rear steel plate, do not affect the flexible of its below oil cylinder bar.The ore dropping out from scraper bowl drop on front spring and the upper surface of steel plate, and both sides shunting to the left and right falls earthward.Thereby effectively protect oil cylinder bar, extended the working life of Hydraulic System of LHD Unit.Upper surface at front spring and rear steel plate is bolted respectively the rubber pad that one deck is convenient for changing, and has extended the working life of front spring and rear steel plate.
Brief description of the drawings
Fig. 1 is structure of the present utility model and working principle schematic diagram.
embodiment
Further illustrate the utility model below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model comprises oil cylinder seat, and oil cylinder seat is connected with connecting rod by its oil cylinder bar, and the front end of connecting rod is used for installing scraper bowl.
The utility model also comprises the rear hinged-support 1 that is arranged on oil cylinder seat front end upside and the front hinged-support 7 that is arranged on connecting rod upside.Wherein, on hinged-support 1, rear rotating shaft 2 is installed, on front hinged-support 7, front rotary shaft 6 is installed.Also comprise that rear steel plate 3 and front end that rear end is arranged in rear rotating shaft 2 are arranged on the front spring 5 on front rotary shaft 6, the rear end of the front end of rear steel plate 3 and front spring 5 is connected to each other by center hinge spindle 4.The front end and back end of described front spring 5 and rear steel plate 3 is articulated form and installs, and does not affect the flexible of its below oil cylinder bar.
In order to improve the working life of front spring 5 and rear steel plate 3, be bolted respectively one deck rubber pad at the upper surface of front spring 5 and rear steel plate 3.
On scraper bowl, carry in process, the ore front spring 5 dropping out from scraper bowl and the upper surface of steel plate 3, and both sides shunting to the left and right falls earthward, thereby plays the protective action to its below oil cylinder bar.
