Background technology
Excavator is a kind of multipurpose restoration in earth-rock construction machinery, is substantially carried out the cubic metre of earth and stone and excavates, loads, can also carry out soil
It is smooth, repair slope, lifting, it is broken, remove, the operation such as trench digging, so being built in the road constructions such as highway, railway, bridge construction, city
If, be widely applied in airport harbour and water conservancy construction.The general bag lift arm of digging arm of excavator used at present
With the joint arm of bucket arm two, swing arm is referred to as, but the direction above in general excavator swing arm and rotating disk between driver's cabin is
It is relatively-stationary, the front of driver's cabin is stretched to, and can only be rotated with rotating disk and driver's cabin, this is in the larger place construction in space
When completely can be with, but when side space is limited, it is no longer just two parallel sides to dig out the side of ditch two come, all after
Continuous work has an impact；There is technical scheme to take into account this problem in the prior art, Patent No. 201420639432.2, specially
Profit is entitled：A kind of patent of new horizontal swinging arm excavator describes a kind of set in lift arm and bucket arm side and swings oil
The scheme of cylinder, swinging for lift arm and bucket arm is realized, can solve this problem to a certain extent；But one
Side sets oil cylinder drawback clearly, is significantly less than the swing angle to opposite side to oil cylinder side swing angle, and this is to excavating
Environmental requirement is higher, and ditch position has to the opposite side in excavator swing arm oil cylinder, ineffective to expansion excacation.
The content of the invention
To solve the above problems, overcome the deficiencies in the prior art, the utility model provides a kind of two-way equal big corner
Excavator swing arm lateral movement mechanism.
To achieve the above object, excavator swing arm lateral movement mechanism provided by the utility model, including car body, steering mechanism,
Swing arm；Steering mechanism includes E fonts link, oil cylinder；The steering mechanism by be arranged at E font links lower plywood and
Rotating shaft between middle plate is hinged with car body front end, and the E fonts link front end is connected with swing arm；The oil cylinder includes first
Oil cylinder, the second oil cylinder, the piston rod front end and E fonts link rotation connection of first oil cylinder, the second oil cylinder, described the
One oil cylinder, the afterbody of the second oil cylinder and car body are hinged.
Further, the rotating shaft is arranged on the horizontal axis of E font link lower plywoods and middle plate.
Further, the top of top plate one end of the E fonts link is provided with cylindrical first connecting pole, described
First connecting pole is connected with the piston rod front end of the first oil cylinder with rotating manner；The top plate other end of the E fonts link
Bottom be provided with cylinder the second connecting pole, the piston rod front end of second connecting pole and the second oil cylinder is with rotating manner
Connection.
Further, first oil cylinder, the afterbody of the second oil cylinder are vertical with the wedge shaped support block that is arranged on car body
Plane is hinged, and pin joint is in same vertical straight line.
The beneficial effects of the utility model are：The double oil cylinder controls of the utility model rotate, more stable, and can realize swing arm
Swing equal angular, realizes that excavator is limitedly digging out straight ditch in rotation space；In swing arm to the first oil cylinder
Side rotate when, the first oil cylinder shrink, the second oil cylinder elongation, realize E fonts link drive swing arm rotate axially the first oil cylinder
Side rotates；Otherwise swing arm to the second oil cylinder side rotates when, the first oil cylinder elongation, the second oil cylinder shrink, realize E fonts connection
Frame drive swing arm rotate axially the second oil cylinder side rotate.

Embodiment：
To make the purpose, technical scheme and advantage that the utility model is implemented clearer, below in conjunction with the utility model
Accompanying drawing, the utility model is further described in more detail.
In to description of the present utility model, it is to be understood that indicating position or position relationship are described as based on attached
Orientation or position relationship shown in figure, it is for only for ease of and describes the utility model and simplify to describe, rather than instruction or hint
Signified device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this
The limitation of utility model protection scope.In addition, term " first ", " second " are only used for describing purpose, and it is not intended that instruction
Or imply relative importance.
, it is necessary to which explanation, unless otherwise clearly defined and limited, term " is set in description of the present utility model
Put ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integratedly
Connection；Can be mechanical connection or electrical connection；Can be joined directly together, can also be indirectly connected by intermediary,
It can be the connection of two element internals.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
Concrete meaning of the language in the utility model.
In accompanying drawing 1 and accompanying drawing 2, to achieve the above object, the lateral movement mechanism of excavator swing arm 1 provided by the utility model,
Including car body 4, steering mechanism, swing arm 1；Steering mechanism includes E fonts link 2, oil cylinder 3；E fonts link 2 includes upper strata
Plate, lower plywood and middle plate, the steering mechanism are turned by being arranged between the lower plywood and middle plate of E fonts link 2
Axle 7 is hinged with the front end of car body 4, and the front end of E fonts link 2 is connected with swing arm 1；The oil cylinder 3 includes the first oil cylinder 31, the
Two oil cylinders 32, first oil cylinder 31, piston rod front end and the E fonts link 2 of the second oil cylinder 32 are rotatablely connected, and described the
One oil cylinder 31, the afterbody of the second oil cylinder 32 and car body 4 are be hinged.
