Description
Technical field:
The utility model relates to sweeper accessory technical field, is specifically related to a kind of sweeper lifting gear.
Background technology:
Develop rapidly along with economy, the construction in city also thereupon high speed development get up, the hand sweeping of urban pavement has been difficult to satisfy the demand of growing urban road, therefore, the demand of the road sweeper that industry is developed is also growing, the use of sweeper not only expands to the small city from big and medium-sized cities, speedway, and much enterprises, residential quarter also adopt sweeper to carry out road cleaning, the rapid expansion of the market demand makes the competition between the sweeper manufacturing enterprise also thereupon fierce.Although the development of China's sweeper technology makes the world attract attention,, compared with developed countries, also there are many gaps in China's road sweeper.The sweeper of China is suitable with level of developed countries at cleaning work aspect of performances such as sweeping efficiency, cleaning ability, dust removing effects, but in the reliability of sweeper, comfortableness, still there is larger gap in the aspect such as adjustment automatically.Especially the dish of sweeping the floor of sweeper needs lifting, and present sweeper elevating mechanism adopts hydraulic elevation type or pneumatic lifting mostly, complex structure, and volume is larger, and its stability is not, and is fragile.
The utility model content:
The purpose of this utility model provides a kind of sweeper lifting gear, and its adopts the design of parallelogram, and is simple and reasonable, has reduced volume, is promoting or is transferring when sweeping the floor dish, and stability is high, and is not fragile.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises fixed arm, the first oil cylinder, linking arm, the second oil cylinder, lever arm, motor and the dish mounting head of sweeping the floor, one end of fixed arm and an end of linking arm are movable hinged, the other end of linking arm and the upper end of lever arm are movable hinged by pin, be connected with the first oil cylinder between fixed arm upper end and the linking arm upper end, be connected with the second oil cylinder between fixed arm lower end and the lever arm end, lever arm front end below is provided with motor and the dish mounting head of sweeping the floor, and motor is connected with the dish mounting head of sweeping the floor.
Described fixed arm end is provided with connecting hole, and fixed arm is connected with underbelly by connecting hole.
Described the first oil cylinder, the second oil cylinder are parallel to each other, and the tail end of the first oil cylinder, the second oil cylinder is the movable top and bottom that are hinged on fixed arm respectively, and the tailpiece of the piston rod of the first oil cylinder, the second oil cylinder is respectively by the movable upper end of linking arm and the end of lever arm of being hinged on of pin.
Principle of the present utility model is: the piston rod of the first oil cylinder stretches out, during the piston rod indentation of the second oil cylinder, the piston rod of the first oil cylinder drives linking arm and moves downward, the piston rod of the second oil cylinder drags the end of lever arm backward, cause the lever arm front end to move down, descend thereby band is installed in the moving dish of sweeping the floor of sweeping the floor dish mounting head lower end; Opposite, the piston rod indentation of the first oil cylinder, when the piston rod of the second oil cylinder stretches out, the piston rod of the first oil cylinder drives linking arm and moves upward, the piston rod of the second oil cylinder promotes forward the end of lever arm, cause moving on the lever arm front end, thereby be with the dish rising of sweeping the floor that is installed in the moving dish mounting head lower end of sweeping the floor, owing to the first oil cylinder, the second oil cylinder are parallel to each other, therefore stability is high.
The utility model adopts the design of parallelogram, and is simple and reasonable, reduced volume, promoting or transferring when sweeping the floor dish, and stability is high, and is not fragile.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
With reference to Fig. 1, this specific embodiment is by the following technical solutions: it comprises fixed arm 2, the first oil cylinder 3, linking arm 5, the second oil cylinder 6, lever arm 7, motor 8 and the dish mounting head 9 of sweeping the floor, one end of fixed arm 2 and an end of linking arm 5 are movable hinged, the upper end of the other end of linking arm 5 and lever arm 7 is movable hinged by pin 4, be connected with the first oil cylinder 3 between fixed arm 2 upper ends and linking arm 5 upper ends, be connected with the second oil cylinder 6 between fixed arm 2 lower ends and lever arm 7 ends, lever arm 7 front ends below is provided with motor 8 and the dish mounting head 9 of sweeping the floor, and motor 8 is connected with the dish mounting head 9 of sweeping the floor.
Described fixed arm 2 ends are provided with connecting hole 1, and fixed arm 2 is connected with underbelly by connecting hole 1.
Described the first oil cylinder 3, the second oil cylinder 6 are parallel to each other, and the tail end of the first oil cylinder 3, the second oil cylinder 6 is the movable top and bottom that are hinged on fixed arm 2 respectively, and the tailpiece of the piston rod of the first oil cylinder 3, the second oil cylinder 6 is respectively by the pin 4 movable upper end of linking arm 5 and the ends of lever arm 7 of being hinged on.
The principle of this specific embodiment is: the piston rod of the first oil cylinder 3 stretches out, during the piston rod indentation of the second oil cylinder 6, the piston rod of the first oil cylinder 3 drives linking arm 5 and moves downward, the piston rod of the second oil cylinder 6 drags the end of lever arm 7 backward, cause lever arm 7 front ends to move down, descend thereby band is installed in the moving dish of sweeping the floor of sweeping the floor dish mounting head 9 lower ends; Opposite, the piston rod indentation of the first oil cylinder 3, when the piston rod of the second oil cylinder 6 stretches out, the piston rod of the first oil cylinder 3 drives linking arm 5 and moves upward, the piston rod of the second oil cylinder 6 promotes forward the end of lever arm 7, cause moving on lever arm 7 front ends, thereby be with the dish rising of sweeping the floor that is installed in moving dish mounting head 9 lower ends of sweeping the floor, owing to the first oil cylinder 3, the second oil cylinder 6 are parallel to each other, therefore stability is high.
This specific embodiment adopts the design of parallelogram, and is simple and reasonable, reduced volume, promoting or transferring when sweeping the floor dish, and stability is high, and is not fragile.
