Abstract
The utility model provides a lifting device of a sweeper. The lifting device of the sweeper comprises a rack, edge brushes, edge brush movable rocker arms and electric push rods. The edge brushes are arranged on the rack in a liftable mode through the edge brush movable rocker arms. The lifting device of the sweeper is characterized in that the electric push rods are connected with the edge brush movable rocker arms through connecting arms, the electric push rods carry out stretching-retracting movement to drive the connecting arms to rotate, the connecting arms rotate to drive the edge brush movable rocker arm to rise and descend, and thus the edge brushes are driven to rise and descend. According to the structural improvement design, the edge brush movable rocker arms are connected with the electric push rods, the electric push rods directly pull the edge brush movable rocker arms, load-bearing of the electric push rods is reduced because of the lever principle of rocker arm rods, the electric push rods are protected against burnout because of damage caused by long-term heavy load, cost is reduced, and the number of faults is reduced.
Description
Technical field
The utility model relates to a kind of cleaning device, relates in particular to a kind of lowering or hoisting gear of sweeper.
Background technology
Sweeper is used on the cleaning widely as clearing apparatus, and lifting and the lifting of electric pushrod pulley-type of hydraulic pressure are arranged in the homemade electric sweeper.The former has high input, the cost height.Latter's load is excessive, electric pushrod fault height.Therefore need a kind of low cost, the sweeper lowering or hoisting gear that fault rate is low.
The utility model content
In order to solve the above problem that exists in the background technology, the utility model provides a kind of sweeper lowering or hoisting gear, and this device is the sweeper lowering or hoisting gear of a kind of low cost, less trouble.
For achieving the above object, the utility model adopts following technical scheme:
A kind of sweeper lowering or hoisting gear, comprise frame, limit brush, the movable rocking arm of limit brush and electric pushrod, movable rocking arm is liftable is arranged on the frame by the limit brush for described limit brush, it is characterized in that, described electric pushrod is connected by the movable rocking arm of link arm and described limit brush, the electric pushrod stretching motion drives link arm and rotates, and link arm rotates and drives the movable rocking arm lifting of limit brush, and then drives limit brush lifting.
Described limit brush comprises that brush in two front-seat fronts and two back brushes of back row.
Described limit brushes and is provided with limit brush motor.
The beneficial effects of the utility model are: after the structural improvement design; utilization activity rocking arm and electric pushrod join; electric pushrod direct pull rocking arm reduces because the lever principle of rocking lever allows electric pushrod bear a heavy burden, and has protected electric pushrod to burn out because of long-term heavy duty infringement.Not only low cost but also reduced fault.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified
Fig. 1 is the structural representation of the utility model embodiment 1;
The specific embodiment
Below in conjunction with description of drawings and the specific embodiment the utility model is further described:
Embodiment 1
As shown in Figure 1, a kind of sweeper lowering or hoisting gear, comprise frame 1, front and back two row limit brushes 2, the movable Rocker arm 4 of limit brush and electric pushrod 5, the elevating mechanism of back row limit brush is such: movable Rocker arm 4 is liftable is arranged on the frame 1 by the limit brush for described limit brush 2, brush movable Rocker arm 4 in described limit comprises two vertical connecting rods 7 and the tranverse connecting rod 8 that is connected two vertical connecting rods that are connected on the frame, described electric pushrod 5 comprises perpendicular push rod 9 and rotating shaft 10, and the rotating shaft 10 of described electric pushrod is connected by link arm 11 with the tranverse connecting rod 8 of the movable rocking arm of described limit brush.
The elevating mechanism of front-seat limit brush is that electric pushrod 5 does not have rotating shaft, directly connects with link arm 11 by perpendicular push rod 9 to link to each other, and link arm 11 links to each other with the tranverse connecting rod of the movable rocking arm of limit brush.
During work, the course of work of row limit, back brush is such: the perpendicular push rod 9 of electric pushrod 5 moves upward, and rotating shaft 10 is rotated, and drives link arm 11 and upwards rotates, and the tranverse connecting rod 8 that the rotation of link arm 11 drives the movable Rocker arm 4 of limit brush moves upward, and rises thereby drive limit brush 2.The perpendicular push rod 9 of electric pushrod 5 moves downward, and rotating shaft 10 is rotated, and drives link arm 11 and rotates, and the tranverse connecting rod 8 that the rotation of link arm 11 drives the movable Rocker arm 4 of limit brush moves downward, and falls thereby drive limit brush 2, and kiss the earth is started working then.The course of work of front-seat limit brush similarly.Repeat no more.
It will be recognized by those skilled in the art, under the prerequisite that does not depart from protection scope of the present invention, can carry out various modifications, variation and combination to above-mentioned embodiment, and think that this modification, variation and combination are within the scope of originality thought.
Claims (3)
