Abstract
The invention discloses an oil cylinder steering device for a double steel-wheel vibroroller, and belongs to the technical field of double steel-wheel vibrorollers. The oil cylinder steering device comprises a back frame (8), a hinged joint (1) and a steering oil cylinder 1 (2). One end of the steering oil cylinder 1 (2) is movably connected with one side of the hinged joint (1), and the other end is movably connected with the back frame (8); and a steering oil cylinder 2 (21) corresponding to the steering oil cylinder 1 (2) in position is movably connected between the other side of the hinged joint (1) and the back frame (8). According to the invention, a steering oil cylinder is added on the basis of the original road roller so as to improve the steering sensitivity and stability of the road roller, avoid the sticking phenomenon and satisfy the steering requirement on the steering the double steel-wheel vibroroller on the construction site; and two pin shafts for connecting the hinged joint with the back frame in the prior art are replaced by one pin shaft for connection so as to ensure the concentricity and reduce the product cost and simultaneously increase the work efficiency and work quality of the road roller.
Description
Technical field
The present invention relates to a kind of double-steel wheeled vibratory roller oil cylinder transfer, belong to the double-steel wheeled vibratory roller technical field.
Background technology
Vibratory roller is a kind of earthmoving equipment that integrates machinery, hydraulic pressure, electrical technology, realize the mechanism arrangement of compacting soil laying and rock embankment by each base part, because what existing dual-steel wheel road roller adopted links together with two bearing pin articulated joints and rear vehicle frame, this connected mode is very accurate to the part that articulated joint is connected with rear vehicle frame, concentricity is difficult to guarantee, very strict to processing request, thus cost of production improved.What existing dual-steel wheel road roller adopted in addition is single hydraulic oil cylinder driving, and it is not very sensitive causing when turning to, and it is time-consuming to require great effort, and affects again efficiency of construction.Particularly in pavement roughness, this phenomenon is more obvious.Also stuck phenomenon can appear sometimes.
Summary of the invention
The purpose of this invention is to provide a kind of double-steel wheeled vibratory roller oil cylinder transfer, can make road roller turn to sensitivity, avoid the appearance of stuck phenomenon, guarantee simultaneously the concentricity when articulated joint is connected with rear vehicle frame, reduce production costs.
For achieving the above object, double-steel wheeled vibratory roller oil cylinder transfer of the present invention, comprise rear vehicle frame, articulated joint and steering cylinder one, steering cylinder is held one by one with hinged first side and is flexibly connected, the other end and rear vehicle frame are flexibly connected, and are flexibly connected a steering cylinder two corresponding with steering cylinder one position between articulated joint opposite side and rear vehicle frame.
As improvement of the present invention, the present invention respectively installs an anchor bearing in two holes up and down at rear vehicle frame, turn to bearing pin to pass anchor bearing and articulated joint, articulated joint is connected together with rear vehicle frame, rear vehicle frame turns to bearing pin to be connected with articulated joint by one, guarantee concentricity, time saving and energy saving, reduce production costs simultaneously;
As a further improvement on the present invention, steering cylinder one and steering cylinder two are by steering bearing and turn to bearing pin to be installed in the articulated joint, reduce the friction between steering cylinder and the articulated joint, prolong its application life.
The invention has the beneficial effects as follows:
1. set up a steering cylinder on original road roller basis, improve sensitivity and stability that road roller turns to, avoid the appearance of stuck phenomenon, satisfy on the building site the demand of double-steel wheeled vibratory roller to turning to.
2. articulated joint in original technology and rear vehicle frame are linked together by two bearing pins and use a bearing pin instead and be connected, guarantee that concentricity has reduced cost of production, improve simultaneously operating efficiency and the work quality of road roller.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is part section structural representation of the present invention;
The specific embodiment
The present invention will be described below in conjunction with drawings and Examples.
As shown in Figure 1, the present invention is by comprising rear vehicle frame 8, articulated joint 1 and steering cylinder 1, steering cylinder one 2 one ends and articulated joint 1 one sides are flexibly connected, the other end and rear vehicle frame 8 are flexibly connected, it is characterized in that, between articulated joint 1 opposite side and rear vehicle frame 8, be flexibly connected a steering cylinder two 21 corresponding with steering cylinder one 2 positions.
As shown in Figure 2, be one embodiment of the invention, in two holes an anchor bearing 7 respectively is installed at rear vehicle frame about in the of 8, anchor bearing 7 two ends are respectively equipped with and turn to bearing pin 4, turn to bearing pin 4 bottoms cover that lock sleeve is arranged, lock sleeve 6 screws tight by locking nut 5 and is turning on the bearing pin 4, anchor bearing 7 places two to turn between the bearing pin, articulated joint 1 is connected together with rear vehicle frame 8, this kind structure is identical with the technique effect that prior art reaches, and simpler than prior art installation steps, has avoided simultaneously when connecting hinge joint 1 and rear vehicle frame 8, expend time in and aim at two drawbacks that turn to bearing pin 4 rear installations, can finish installation work with the short time, the time time saving and energy saving, reduce production costs, increase work efficiency
In order to reduce the friction between steering cylinder and the articulated joint 1, prolong its application life simultaneously, the present invention adopts steering bearing 9 and turns to bearing pin 4 that steering cylinder and articulated joint 1 are linked together.
Operating principle of the present invention: the motor on the double-steel wheeled vibratory roller is passed to steering pump with power, steering pump is passed to steering cylinder with power, thereby drive the steering cylinder free-extension, because rear vehicle frame 8 links together with two anchor bearings 7 of articulated joint 1 usefulness, the later vehicle frame 8 of institute and articulated joint 1 can freely be rotated under the effect of anchor bearing 7.Because steering cylinder one end is connected in the articulated joint 1, the other end is connected on the rear vehicle frame 8, so when steering cylinder was done stretching motion, rear vehicle frame 8 rotated relative to articulated joint 1, thereby has realized the purpose that double-steel wheeled vibratory roller turns to again.
