Description
Technical field
The utility model relates to a kind of crawler belt technology of construction machinery and equipment, and especially a kind of telescoping crawler body is applicable to various construction machinery and equipments.Belong to technical field of engineering machinery.
Background technology
Because the crawler-type traveling mode has comformability and alerting ability concurrently, so tracked construction equipment becomes current application one of construction machinery and equipment the most widely.
Along with the development of engineering technology, engineer operation is also had higher requirement to tracked construction equipment, such as, in recent years, the fast development of pile foundation engineering in the building engineering, super-high buildings constantly increases, and the diameter of pile foundation and the degree of depth also constantly increase.The increase of the pile foundation diameter and the degree of depth is had higher requirement to the stability of piling machinery.For satisfying this demand, just require in construction operation, the caterpillar chassis width can increase, for piling machinery provides bigger longitudinal ligament span.Equally, when and other engineer machinery operation also identical requirement has been proposed corresponding tracked construction equipment, when construction operation, require crawler body that bigger width is arranged, to guarantee the stability of construction machinery and equipment.
The stability problem when though the width of increase crawler body can solve construction operation; But the width that increases crawler body merely means size and the weight that increases the chassis; Thereby bring manufacturing cost to improve, a series of problems such as the reduction of complete machine alerting ability and transition hard transportation, therefore; Be difficult to coordinate the comformability of stability, alerting ability and the transition transportation of construction operation merely through the width that increases crawler body, be difficult to satisfy the demand of modern project technical development.
The utility model content
The purpose of the utility model is that alerting ability is low, the problem of transition hard transportation for the crawler body that solves prior art exists, and a kind of telescoping crawler body rational in infrastructure, lower-cost is provided.
The purpose of the utility model can reach through following technical scheme:
The telescoping crawler body; Comprise bearing and the track frame that is symmetricly set on the bearing both sides; Its constructional feature is: between track frame and bearing, be connected with telescopic oil cylinder, in the installed inside of track frame bearing support arranged, said bearing support is through swing arm and bearing flexible connection; The two ends of swing arm are hinged with bearing support, bearing respectively, the parallelogram telescoping mechanism that can swing forward through swing arm and bearing support, the hinged formation of bearing.
The purpose of the utility model can also reach through following technical scheme:
A kind of embodiment of the utility model is: around bearing, can be symmetrically arranged with one of strut member, respectively be provided with two of strut member in the front and rear portions of the track frame of both sides.
A kind of embodiment of the utility model is: one of said strut member can have four; Be separately positioned on left forward, left rearward, right front portion, the right back portion of bearing, one of each strut member is respectively through fixedly two corresponding connections of strut and the strut member of both sides track frame of an easily detachable.
A kind of embodiment of the utility model is: the junction at said bearing and swing arm can be provided with one of bearing pin, can be provided with two of bearing pin in the junction of bearing support and swing arm.
The utility model is applicable to all tracked construction equipments.
The utlity model has following outstanding beneficial effect:
1, because each bearing support of crawler body of the utility model and bearing form the parallelogram telescoping mechanism; Therefore; Satisfying on the basis of structural strength, realizing bigger longitudinal ligament span, farthest satisfying the stability requirement of construction machinery and equipment with respect to the crawler body of prior art.
2, the crawler body of the utility model is under travelling position; Make the parallelogram telescoping mechanism shrink swing through swing arm, move behind the left and right track frame, can effectively change the gravity centre distribution of complete machine; Improve the grounding pressure of complete machine greatly, improved the transport performance of equipment.
3, the crawler body of the utility model is rational in infrastructure, has reduced manufacturing cost, can be widely used in having satisfied the demand of engineering development well in the crawler-mounted construction machinery and equipment.

Fig. 3 is the contraction state perspective view of the utility model specific embodiment 1.
Fig. 4 is the contraction state planar structure scheme drawing of the utility model specific embodiment 1.
Wherein, the 1-bearing, the 2-track frame, the 3-telescopic oil cylinder, the 4-bearing support, the 5-swing arm, one of 6-strut member, two of 7-strut member, 8-is strut fixedly, one of 9-bearing pin, two of 10-bearing pin.
The specific embodiment
Specific embodiment 1:
Fig. 1 and Fig. 2 constitute the specific embodiment 1 of the utility model.
See figures.1.and.2; Present embodiment comprises bearing 1 and the track frame 2 that is symmetricly set on bearing 1 both sides; Between track frame 2 and bearing 1, be connected with telescopic oil cylinder 3, in the installed inside of track frame 2 bearing support 4 arranged, said bearing support 4 flexibly connects through swing arm 5 and bearing 1; The two ends of swing arm 5 are hinged with bearing support 4, bearing 1 respectively, the parallelogram telescoping mechanism that can swing forward through swing arm 5 and bearing support 4, bearing 1 hinged formation.
In the present embodiment, around bearing 1, be symmetrically arranged with one of strut member 6, respectively be provided with 27 of strut member in the front and rear portions of the track frame 2 of both sides.One of said strut member 6 has four, is separately positioned on left forward, left rearward, right front portion, the right back portion of bearing 1, and one of each strut member 6 is respectively through fixedly 27 corresponding connections of strut 8 and the strut member of both sides track frame 2 of an easily detachable.Junction at said bearing 1 and swing arm 5 is provided with one of bearing pin 9, is provided with 2 10 of bearing pin in the junction of bearing support 4 and swing arm 5.
The utility model is applicable to all tracked construction equipments.
With reference to Fig. 3 and Fig. 4, be the contraction state of present embodiment, fixedly strut 8 is pulled down earlier; Through swing arm 5 bearing support 4 and the parallelogram telescoping mechanism that bearing 1 forms are shunk again; Telescopic oil cylinder 3 begins to shrink, and simultaneously, bearing 1 is swung forward; Thereby move after making left and right track frame 2, can transport goods then.
