The telescopic base plate is reasonable in structure, works stably and is convenient to install and transport. The telescopic base plate comprises a main vehicle frame, a left travelling caterpillar frame and a right travelling caterpillar frame, wherein the left travelling caterpillar frame and the right travelling caterpillar frame are respectively arranged at the left side and the right side of the main vehicle frame, telescopic connecting devices are respectively arranged between the left travelling caterpillar frame and the main vehicle body and between the right travelling caterpillar frame and the main vehicle body.
Description
Technical field
The utility model relates to a kind of engineering machinery chassis structure, particularly a kind of traxcavator retractable chassis.
Background technology
Chassis portion in the running gear of existing large excavator generally is made up of main car frame and the left and right traveling crawler frame of being located at the main car frame and arranged on left and right sides; Said left and right traveling crawler frame is weldingly fixed on the main car frame both sides and forms an entire track chassis of dredging machine; Because existing chassis of dredging machine is the integral type Type of Welding; Thereby can't regulate the distance between main car frame and the left and right traveling crawler frame; Limited the crossing ability of car load when advancing and the stability of complete machine work, also can't main car frame and left and right sides traveling crawler frame have been split, caused large-scale or the ultra-large type excavating machine tends to overweight, ultra wide or superelevation when utilizing vehicular transport; Thereby cause hard transportation, exist hidden danger.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of above-mentioned technology, thereby a kind of rational in infrastructure, stable working, installation and transportation traxcavator retractable chassis easily is provided.
The technical scheme that the utility model adopted is such: a kind of traxcavator retractable chassis; Comprise that main car frame, left lateral are walked track frame and right lateral is walked track frame; Said left and right traveling crawler frame is located at the left and right sides of main car frame respectively, is provided with scalable connecting device between said left and right traveling crawler frame and the main car frame.
Further: said scalable connecting device is: said left and right traveling crawler frame and that side of main car frame bonded assembly are respectively equipped with guide rail; Be respectively equipped with the slotted eye of assigning guide rail on the position of the corresponding left and right traveling crawler frame guide rail in the said main car frame left and right sides; Said left and right traveling crawler frame is located in the main car frame slotted eye through what the guide rail on it can horizontally slip; Said main car frame middle part is installed with telescopic oil cylinder, and the two-piston bar of said telescopic oil cylinder connects left and right traveling crawler frame respectively.
Further: the position of corresponding slotted eye is provided with dowel bolt on the said main car frame, and said guide rail upper end has positioning runner, and said dowel bolt is stuck in the guide rail positioning runner.
Through adopting the aforementioned techniques scheme; The beneficial effect of the utility model is: this novel crawler-type excavating machine retractable chassis; Be provided with scalable connecting device between said left and right traveling crawler frame and the main car frame; Through the telescopic oil cylinder scalable main car frame of flexible connecting device and the distance between the traveling crawler frame of the left and right sides, car load advance through the time, adopt flexible state; During work, adopt and stretch out state, promoted the stability of complete machine work and the crossing ability of car load significantly; During transportation, only need to need not dismounting to left and right traveling crawler frame withdrawal, saved traffic cost and dismounting time.
Description of drawings
Fig. 1 is the utility model example structure scheme drawing;
Fig. 2 is the utility model embodiment three-dimensional exploded view.
The specific embodiment
Further specify the utility model below in conjunction with the accompanying drawing and the specific embodiment.
Like Fig. 1 to Fig. 2; A kind of traxcavator retractable chassis; Comprise that main car frame 1, left lateral are walked track frame 2 and right lateral is walked track frame 3; Said left lateral is walked track frame 2 and is walked the left and right sides that track frame 3 is located at main car frame 1 respectively with right lateral; Said left lateral is walked track frame 2, right lateral and is walked track frame 3 and be installed with two guide rails 4 respectively with that side of main car frame 1 bonded assembly, said guide rail that direction is set is vertical each other with the direction of crawler belt operation, the corresponding left lateral in said main car frame 1 left and right sides is walked track frame 2 and right lateral and is walked on the position of track frame 3 guide rails to be respectively equipped with 4 slotted eyes 11 assigning 4 guide rails 4; Said left lateral is walked track frame 2 and right lateral and is walked in the slotted eye of being located at main car frame 1 11 that track frame 3 can horizontally slip through the guide rail on it 4; Said main car frame 1 middle part laterally is installed with telescopic oil cylinder 5, and the two-piston bar of said telescopic oil cylinder 5 connects left and right traveling crawler frame respectively, and the position of corresponding slotted eye is provided with dowel bolt 6 on the said main car frame 1; Said guide rail 4 upper ends have chute 41, and said caging bolt 6 is stuck in the guide rail chute 41.
This novel crawler-type excavating machine retractable chassis can promote left and right traveling crawler frame through the two-piston bar of telescopic oil cylinder on the main car frame and do expansion and contractile motion; Thereby regulate the distance between main car frame and the left and right traveling crawler frame; Car load advance through the time can adopt contraction state, improved the crossing ability of car load; During work; Can be according to service condition through stretching or shrink the bearing surface distance that the spacing between the two traveling crawler framves is regulated the chassis; Well solved the demand when car load is in different conditions; Guaranteed stationarity and the safety of machine under various complicated applied force operating modes, maximum performance its working ability, improved work efficiency; During transportation, only need to need not dismounting to left and right traveling crawler frame withdrawal, saved traffic cost and dismounting time.
More than show and described groundwork and the principal character and the advantage thereof of the utility model; The technical personnel of the industry should be understood; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the explanation that the utility model just is described, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications; These variations and improvement all fall in the utility model scope that requires protection, and the utility model requires protection domain to be defined by appending claims and equivalent thereof.
