Abstract
The utility model provides a component of an excavator, and particularly relates to a telescopic underframe of the excavator. The telescopic underframe comprises a left crawler device, a right crawler device and a connecting frame, and further comprises a telescopic oil cylinder, wherein the telescopic oil cylinder is fixedly connected to the connecting frame; and two telescopic rods of the telescopic oil cylinder are connected with the left and the right crawler devices respectively. During the use of the telescopic underframe, a driver in a cab of a platform can operate the telescopic oil cylinder through a hydraulic servo, so as to expand or contract the underframe according to the working conditions. When the excavator works, the left crawler device and the right crawler device are stretched out, so as to enlarge the land pressing range of the chassis of a mini-type hydraulic excavator, which improves the working stability and the excavating force of the mini-type hydraulic excavator. When the excavator moves or is stored, the left and the right crawler devices can be contracted, so as to save occupied area and storage space, which ensures that the mini-type hydraulic excavator can move on a narrow road.
Description
Technical field
The utility model is a kind of excavator parts, relates in particular to a kind of excavator extension type underframe.
Background technology
Along with socio-economic development, increasing object of construction production needs excavator to carry out earthwork, and excavator has also obtained application more and more widely in real work.Small type hydraulic excavator is in light weight; In order to walk on narrow road surface; Usually the chassis is designed to the deflation pattern; But because this chassis floor space is little, be labile state during excacation, be badly in need of a kind of excavator underframe
that can satisfy job stability and the walking of suitable narrow road surface simultaneously at present.
Summary of the invention
The utility model is to the deficiency of prior art, and providing a kind of can increase job stability, the excavator extension type underframe of walking applicable to narrow road section again.
The technical scheme of the utility model is to realize like this.
A kind of excavator extension type underframe comprises left crawler attachment, right-hand track chiain device, link.Wherein, Said left crawler attachment is equipped with left crawler belt telescoping catheter; The right-hand track chiain device is equipped with the right-hand track chiain telescoping catheter, link is equipped with the link telescoping catheter; Said left crawler belt telescoping catheter is movably connected in the link telescoping catheter, and said right-hand track chiain telescoping catheter is movably connected in the left crawler belt telescoping catheter.
As the further scheme of the utility model, left crawler attachment and right-hand track chiain device also all are installed with limited block and gag lever post.
As the further scheme of the utility model, excavator extension type underframe also comprises telescopic oil cylinder, and said telescopic oil cylinder is fixedly connected on the link, and two expansion links of telescopic oil cylinder are connected with the right-hand track chiain device with left crawler attachment respectively.
When the utility model used, the driver can handle telescopic oil cylinder through hydraulic servo in the driver's cabin of platform, and can operate the flexible of underframe according to operating mode thus.When excavator operation, left crawler attachment and right-hand track chiain device are trailed, can increase the small type hydraulic excavator chassis by the ground scope, and then the stability when increasing excavator work, improve digging force.When excavator walking or when depositing, collapsible left crawler attachment and right-hand track chiain device are with the purpose that reaches saving floor space and parking space, can walk in narrow road.
