Abstract
The utility model relates to a lower vehicle track frame structure of an excavating machine, which comprises a lower vehicle frame and is characterized in that two square hole structures are arranged inside the lower vehicle frame, guide rails are welded on a left track frame and a right track frame respectively, the travel direction of the guide rails is perpendicular to the movement direction of a track, the guide rails on the left track frame and the right track frame are mounted in the square holes inside the lower vehicle frame, the left and the right track frames are fixedly connected at two ends of an expansion oil cylinder respectively, grooves are formed at the upper ends of the guide rails, and positioning bolts that are fixed on the vehicle frame are clamped in the grooves to limit the positions of the left and the right track frames in the extreme positions. The utility model has the advantages of simple and reliable structure and low cost, greatly improves the operating stability and the mobility of the whole machine, and is easily applied to the mini excavating machine.
Description
Technical field
The utility model relates to a kind of track frame structure of getting off of excavating machine, belongs to the excavating machine track frame technical field of getting off.
Background technology
At present, in the track frame structure of getting off of excavating machine, substantially all adopt integral type, in conjunction with decision, this has also just limited complete machine working stability and car load crossing ability to the width between two crawler belts by complete machine working stability and car load crossing ability.
Summary of the invention
The purpose of this utility model provides a kind of track frame structure of getting off of excavating machine, to have solved the problem of complete machine working stability and car load crossing ability.
In order to realize above purpose, the utility model provides a kind of track frame structure of getting off of excavating machine, comprise vehicle frame down, it is characterized in that, two square hole structures are arranged in the following vehicle frame, be welded with guide rail respectively on left side track frame and the right-hand track chiain frame, guide rail that direction is set is vertical mutually with the crawler belt service direction, guide rail on left side track frame and the right-hand track chiain frame is installed in down in the square hole of vehicle frame, left side track frame and right-hand track chiain frame are fixedly connected on expansion oil cylinder two ends respectively, the guide rail upper end has groove, and the dowel bolt that is fixed on the vehicle frame is stuck in the groove, the position of left side track frame and right-hand track chiain frame during the restriction end position.
The utility model has the advantages that simple and reliable for structurely, cost is low, very big lifting complete machine working stability and car load crossing ability, be easy on mini-excavator, implement.
Description of drawings
Fig. 1 is the track frame integral structure scheme drawing of getting off of excavating machine;
Fig. 2 is the track frame disassembled form scheme drawing of getting off of excavating machine.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, be the track frame integral structure scheme drawing of getting off of excavating machine, Fig. 2 is the track frame disassembled form scheme drawing of getting off of excavating machine.The track frame structure of getting off of described excavating machine comprises vehicle frame 2 down, be welded with guide rail on left side track frame 1 and the right-hand track chiain frame 3, guide rail that direction is set is vertical mutually with the crawler belt service direction, guide rail on left side track frame 1 and the right-hand track chiain frame 3 is installed in down in vehicle frame 2 square holes, left side track frame 1 and right-hand track chiain frame 3 are fixedly connected on the two ends of an expansion oil cylinder 5, guide rail upper end has groove, is fixed on the vehicle frame 2 dowel bolt 4 and is stuck in the groove.Expansion oil cylinder 5 is connected by bearing pin respectively with right-hand track chiain frame 3 with left track frame 1, and end position is by down vehicle frame 2 and dowel bolt 4 restrictions, and expansion oil cylinder 5 is flexible to promote left track frames 1 and 3 motions of right-hand track chiain frame, the function that the track frame of realizing getting off is expanded.Car load advance by or when transportation, adopt contraction state; During work, adopt and to stretch out state, demand when well having solved car load and being in different conditions, very big lifting complete machine working stability and car load crossing ability.
