Abstract
The utility model discloses a walking control mechanism of a single-wheel road roller, which is characterized by being provided with a control swing arm by taking a hydraulic control shaft as a rotating fulcrum; one end of the control swinging arm is connected with a soft push-and-pull shaft, and the other end thereof, which is positioned at the left side and the right side of the control swinging arm, is respectively provided with a left limit arm and a right limit arm; the outer sides of the left limit arm and the right limit arm are respectively provided with a left limit block and a right limit block; a return-to-zero limit block is arranged between the left limit arm and the right limit arm; and the front ends of the left limit arm and the right limit arm are respectively connected with a reset tension spring. The utility model provides the walking control mechanism of the single-round road roller which is configured with a hydraulic system in a mini-type road roller with the total mass of being less than 180kg, has small volume and simple structure, and is east to control.
Description
Technical field
The utility model relates to hydraulic pressure single-wheel road roller walking control system, more specifically says so to be used for the rotation of the both forward and reverse directions of single-wheel road roller static pressure gear unit output and the operating-controlling mechanism that stops.
Background technology
The hand steered road roller of the small vibrating of gross weight below 180KG is used for the compacting of road rehabilitation, and at present, the walking transmission system of this class road roller all is to adopt machine driving, its complex structure, manufacturing cost height, and the transmission noise is big.Though hydraulic system has advantages such as the transmission noise is low,, be difficult to the supporting operating-controlling mechanism that is provided with because the space that control system can have is narrow and small relatively.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, for gross mass for the baby roller below the 180KG in the configuration hydraulic system single-wheel road roller walking operating-controlling mechanism that a kind of volume is little, simple in structure, be easy to control is provided.
The utility model technical solution problem adopts following technical scheme.
The design feature of the utility model single-wheel road roller walking operating-controlling mechanism is to be that rotating fulcrum is provided with the control swing arm with the hydraulic control axle, end in described control swing arm connects the push-and-pull flexible axle, in the other end of described control swing arm, the left and right sides that is in described control swing arm left limit arm and right limit arm are set respectively, be respectively arranged with left limit piece and right limit piece in the outside of described left limit arm and right limit arm, between described left limit arm and right limit arm, the return-to-zero limited block be set; The front end of described left limit arm and right limit arm is connected with a reset tension spring respectively.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model is simple in structure, easy to implement
2, the utility model is controlled accurately, is controlled conveniently freely.
Description of drawings
Fig. 1 is the utility model structural representation.
Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Number in the figure: 1 push-and-pull flexible axle, 2 control swing arms, 3 right limit pieces, 4 right limit arms, 5 reset tension springs, 6 return-to-zero limited blocks, 7 left limit arms, 8 left limit pieces, 9 hydraulic control axles.
The specific embodiment
Referring to Fig. 1, it is that rotating fulcrum is provided with control swing arm 2 that the structure of present embodiment is set to hydraulic control axle 9, end in control swing arm 2 connects push-and-pull flexible axle 1, control swing arm 2 the other end, be in control swing arm 2 the left and right sides left limit arm 7 and right limit arm 4 are set respectively, the front end outside of left limit arm 7 and right limit arm 4 is respectively arranged with left limit piece 8 and right limit piece 3, between left limit arm 7 and right limit arm 4 return-to-zero limited block 6 is set; The front end of left limit arm 7 and right limit arm 4 is connected with a reset tension spring 5 respectively.
Present embodiment is to drive control swing arm 2 by push-and-pull flexible axle 1, thereby drives with wearing hydraulic control axle 9 rotations that pin is connected with the control swing arm, drives rolling wheel work thus.
The course of work
When the needs road roller advanced, pulling push-and-pull flexible axle 1 drove hydraulic control axle 9 by push-and-pull flexible axle 1 by control swing arm 2 and is rotated counterclockwise, and controls road roller thus and advances.Road roller retreats when the promotion flexible axle turns clockwise the hydraulic control axle
Each rotation of 21 ° can be implemented to advance or retreat about hydraulic control axle 9 is set in the present embodiment is, guarantees that by extension spring the hydraulic control axle has return-to-zero accurately, thereby road roller is stopped.
