Description
Technical field
The utility model is related to the crawler body structure of heavy duty work car.
Background technology
Crawler body realizes part as the support walking of heavy job engineering car, should possess stronger out-of-flatness ground
Handling capacity, provides firm support in the operating condition again.
Telescopic track chassis, out-of-flatness terrain trafficability is strong, and the speed of travel is fast, and travel position contracting can be met simultaneously
Small lower vehicle-width, the requirement of the lower vehicle-width of working condition increase.But existing crawler body structure is more heavy, there is flexible mill
Damage, easily occur stuck situation.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of flexible crawler body knot for above-mentioned prior art
Structure, reduction flexible abrasion is smooth when improving flexible.
The technical scheme in the invention for solving the above technical problem is：A kind of flexible crawler body, including middle
Support frame is provided with main body and the track frame of both sides, main body, main body both sides are arranged with parallel on extensible canopy, track frame and formed
Telescopic path, the extensible canopy is engaged with Telescopic path, and extensible canopy and Telescopic path can in the presence of telescopic oil cylinder
Relative sliding is to realize flexible adjustment of the track frame with respect to main body, and the inner surface setting of Telescopic path has chute to match extensible canopy
Contact rib, square hole is offered on the track frame, the front end of the Telescopic path is provided with two pass gusset, and rear end part surpasses
Cross on the outside of crawler belt frame body, and the setting rear end gusset between crawler belt frame body.
Preferably, set between Telescopic path and the crawler belt frame body and branch is set again on connecting rib, and connecting rib
Muscle is supportted, one end of brace rod is contacted with Telescopic path, the other end and track frame body contact.In telescopic process, extensible canopy exists
Relative telescopic passage is wanted to slide in the presence of telescopic oil cylinder, Telescopic path will bear huge active force, by setting dowel
Plate and brace rod can provide firm support for Telescopic path.
Further, the Telescopic path inwall is provided with ball, and ball is continuously contacted with extensible canopy in telescopic process,
Increase ball, you can local rolling friction is realized, beneficial to the smooth generation of expanding-contracting action.
Compared with prior art, the utility model has the advantage of：There is provided a kind of flexible crawler body, track frame is relative
Main body can smoothly carry out expanding-contracting action, and overall structure is firmer, act more steady.
Brief description of the drawings
Fig. 1 is the top view of flexible crawler body in the utility model embodiment；
Fig. 2 is the front view of agent structure in the utility model embodiment.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
It is provided with flexible crawler body in the present embodiment, including middle main body 1 and the track frame 2 of both sides, main body 1
Support frame 5, the both sides of main body 1, which are arranged with parallel on extensible canopy 4, track frame 2, forms Telescopic path A, extensible canopy 4 and Telescopic path
A is engaged, extensible canopy 4 and Telescopic path A in the presence of telescopic oil cylinder can Relative sliding to realize that track frame 2 is led relatively
The flexible adjustment of body 1, Telescopic path A inner surface setting has chute to match the contact rib of extensible canopy.Telescopic path inwall
Ball is set, and ball continuously contacts the smooth generation in favor of expanding-contracting action with extensible canopy 4 in telescopic process.
Square hole 3 is offered on track frame 2, Telescopic path A front end is provided with two pass gusset 10, and rear end part exceedes crawler belt
On the outside of frame body, and the setting rear end gusset 6 between crawler belt frame body.
Set between Telescopic path A and crawler belt frame body on connecting rib 7, and connecting rib 7 and brace rod 8 is set again, propped up
One end of support muscle 8 is contacted with Telescopic path, the other end and track frame body contact.
The crawler body of said structure, expanding-contracting action is more smooth, and overall structure is firmer.
In addition to the implementation, the utility model also includes other embodiment, all use equivalents or equivalent
The technical scheme of substitute mode formation, all should fall within the utility model scope of the claims.
Claims (3)
1. support frame is provided with a kind of flexible crawler body, including middle main body and the track frame of both sides, main body, its feature
It is：Main body both sides, which are arranged with parallel on extensible canopy, track frame, forms Telescopic path, and the extensible canopy is contacted with Telescopic path
Coordinate, extensible canopy and Telescopic path in the presence of telescopic oil cylinder can Relative sliding to realize that track frame is flexible with respect to main body
Adjustment, the inner surface setting of Telescopic path has chute and offers square hole on the contact rib of extensible canopy, the track frame to match,
