Abstract
The utility model discloses a single-crawler single-side dual-drive traveling mechanism and a single-crawler multiple drive structure. Two fixed plates are arranged on a crawler beam of the single-crawler single-side dual-drive traveling mechanism, driving wheels and traveling speed reducers are sequentially arranged on the outer sides of the two fixed plates symmetrically, two hydraulic motors are arranged in the middle of the two fixed plates, the two traveling speed reducers drive the two driving wheels simultaneously, and the two driving wheels drive a double-toothed crawler plate to move. The single-crawler single-side dual-drive traveling mechanism is simple in structure and high in practicability, the special crawler plate structure ( the double-toothed crawler plate) is capable of obtaining higher driving power as compared with a conventional crawler plate under specification limitation of the mechanisms (such as hydraulic motors, speed reducers and the like). The crawler plate is better in stress when the traveling mechanism is in need of the same driving power, so that service life of the crawler plate is prolonged. The driving wheels are arranged symmetrically, stress of the crawler beam is improved, and accordingly service life of the crawler beam is prolonged. When the crawler plate structure is applied to an ultra-high-tonnage crawler traveling mechanism, space for arrangement of the driving wheels can be saved effectively, height of a crawler frames can be reduced or the amount of the crawler frames is reduced, so that traveling stability of the whole traveling mechanism is improved.
Description
Technical field
The present invention relates to engineering machinery field, the one-sided two traveling geaies that drive of particularly a kind of wall scroll crawler belt.
Background technology
Continuous increase along with the crawler crane tonnage, requirement to the traveling gear of getting off is more and more higher, and then also increasing to the requirement of motor driven power, however be subjected to the restriction of track frame structural shape and corresponding construction size, and driving speed reducer can not ad infinitum increase.
Summary of the invention
Play an increasingly important role in present national economy in order to overcome the super-tonnage hoisting crane, yet be subjected to the restriction of creeper undercarriage, caterpillar block and drive wheel size, can't obtain the technical matters of needed propulsive effort, the invention provides the one-sided two traveling geaies that drive of a kind of wall scroll crawler belt.
In order to achieve the above object, the one-sided two traveling geaies that drive of a kind of wall scroll crawler belt provided by the invention.The one-sided two crawler belt beams that drive traveling gear of described wall scroll crawler belt are provided with two adapter plates, and the two adapter plates outside is arranged with drive wheel and driving speed reducer successively; Be provided with two groups of HM Hydraulic Motor in the middle of described two adapter plates; Described two driving speed reducers drive two drive wheels, and two drive wheels drive the caterpillar block motion.
Wherein, described twin tooth type caterpillar block is that two engaging tooths are arranged on caterpillar block symmetrically.Wherein, described two groups of HM Hydraulic Motor adopt synchronous driving mode, and described two driving speed reducers drive two drive wheels synchronously, and two drive wheels drive the caterpillar block motion synchronously.
Drive traveling gear according to one-sided pair of the above-mentioned wall scroll crawler belt that provides and to realize that mono-track drives structure more.Described mono-track drives structure more and drives twin tooth type caterpillar block motion realization synchronously by being installed on the one-sided two traveling geaies that drive of the above-mentioned wall scroll crawler belt of crawler belt beam at least two groups.
Wherein, it is 2,3 or 4 that one-sided pair of described wall scroll crawler belt drives traveling gear quantity, realizes successively that respectively mono-track 4 drives structure, mono-track 6 drives structure or mono-track 8 drives structure.
Beneficial technical effects: the present invention is simple in structure, and is practical, is subjected to the restriction of mechanism's (HM Hydraulic Motor, reductor etc.) specification, and this special track plate structure pattern (twin tooth type caterpillar block) can obtain bigger propulsive effort than conventional caterpillar block.When traveling gear needed same propulsive effort, this caterpillar block was stressed better, the service life of having improved caterpillar block.The reductor symmetric arrangement has been improved the stressed of crawler belt beam, has improved the service life of crawler belt beam.Be applied in the super-tonnage creeper undercarriage, can effectively save the space that drive wheel is arranged, and then reduce the height of track frame, improved the stability of complete machine.

The specific embodiment
The present invention is described in detail below in conjunction with drawings and Examples.
With reference to Fig. 1, in the present embodiment, two driving speed reducers drive two drive wheels simultaneously, and two drive wheels drive the motion of twin tooth type caterpillar block, so just can be under limited space, and cloth deposits two driving speed reducers, and enough propulsive efforts can be provided.The reductor symmetric arrangement, it is stressed to have improved the crawler belt girder construction, and the twin tooth type caterpillar block (structure is as shown in Figure 2) that is adopted has simultaneously improved the stressing conditions of caterpillar block, the service life of having improved caterpillar block.
Adopt one-sided two form of driving can realize that the 4 wheel driven, six of wall scroll crawler belt drives and eight drives, as Fig. 3 to shown in Figure 5.
