Description
Technical field
The present invention relates to engineering machinery field, particularly the forward method of a kind of track unit and crawler crane.
Background technology
Crawler crane complete machine weight is generally all larger; in order to increase ground contact area; reduce grounding pressure; track frame and caterpillar block generally all strengthen its length and width in allowed limits as far as possible; and track frame is an integral body, but the result who brings thus is, when track frame carries out monolateral turning to; resisting moment often can occur and provide moment, the phenomenon that crawler crane can't be turned above driving speed reducer.
For above situation, the scheme that generally adopts now is to change motor and driving speed reducer, improves its output torque, but can cause thus the rapid increase of cost, and when normal walking, the ability of hydraulic efficiency pressure system is again less than giving full play to.
Summary of the invention
In view of this, the present invention proposes a kind of track frame and crawler crane, to solve the difficult problem that turns to of crawler crane.
On the one hand, the invention provides a kind of track unit, comprise the left and right sides track frame, be positioned at the caterpillar block of track frame periphery, track frame comprises outer case and internal box, the outer case two ends are provided with track adjusting wheel and drive wheel, it is characterized in that, outer case and internal box bottom are provided with caterpillar wheel, caterpillar wheel is located on the caterpillar block, the caterpillar wheel of internal box bottom is between the caterpillar wheel of outer case bottom, be provided with hydraulic ram between outer case and the internal box, hydraulic ram is used for driving the relative internal box of outer case and moves up.
Further, be provided with guide piece between internal box and the outer case, guide piece comprises guide finger and waist shaped hole, and waist shaped hole is opened on the outer case, and guide finger runs through internal box and outer case.
Further, be provided with wear plate between internal box and the outer case, wear plate is positioned at the both ends of internal box.
Further, internal box is positioned at the outer case middle part, and hydraulic ram is installed on the outer case.
Further, outer case top also is provided with upper track wheel, and upper track wheel is used for supporting the top caterpillar block.
Further, the internal box top is resisted against on the outer case.
Further, when track unit need to turn to, hydraulic ram drove outer case and moves up, and caterpillar block and the ground of outer case below break away from, and track unit relies on the caterpillar block of internal box below to support on the ground; When track unit was normally walked, the caterpillar block of outer case and internal box below all supported on the ground.
Further, caterpillar wheel adopts float grease seal formula or central oiling formula.
A kind of forward method of crawler crane also is provided on the other hand, comprise above-mentioned track unit, when crawler crane need to turn to, hydraulic ram drives outer case and moves up, caterpillar block and the ground of outer case below break away from, and crawler crane relies on the caterpillar block of internal box below to support on the ground; When crawler crane was normally walked, the caterpillar block of outer case and internal box below all supported on the ground.
The forward method beneficial effect of a kind of track unit provided by the invention and crawler crane is: one has solved crawler crane and has turned to hard problem.Its two, simple in structure, cost is low.Its three, be provided with wear plate between outer case and the internal box, the wearing and tearing when reducing relative motion.Its four, adopt the combination of guide finger and waist shaped hole, guarantee interior vertically relative motion of outer case.
Description of drawings
The accompanying drawing that consists of a part of the present invention is used to provide a further understanding of the present invention, and illustrative examples of the present invention and explanation thereof are used for explaining the present invention, do not consist of improper restriction of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of track unit of the present invention;
Fig. 2 is the outer case structural representation among Fig. 1;
Fig. 3 is the internal box structural representation among Fig. 1.
The specific embodiment
Need to prove that in the situation of not conflicting, embodiment and the feature among the embodiment among the present invention can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
As shown in Figure 1 to Figure 3, a kind of track unit comprises track frame and the caterpillar block 3 of the left and right sides, track frame comprises outer case 2 and internal box 1, and internal box 1 is positioned at outer case 2 middle parts and jointly forms track frame, also is wound with caterpillar block 3 on outer case 2 and internal box 1 periphery.
Internal box 1 bottom is provided with caterpillar wheel 10.Its two ends are provided with wear plate 12, and wear plate 12 improves the wear resisting property that internal box 1 and outer case 2 move up and down between internal box 1 and outer case 2.Internal box 1 symmetry offers two through holes 11.Two guide fingers 4 are installed on respectively in two through holes 11, and insert in the waist shaped hole 22 of outer case 2.Guide finger 4 improves the stationary performance that moves up and down between internal box 1 and the outer case 2.When hydraulic ram 24 stretched out, the piston rod of hydraulic ram 24 was resisted against internal box 1 top, so that outer case 2 relative internal box 1 are picked up, thereby so that the caterpillar block 3 of outer case 2 belows breaks away from ground.Caterpillar wheel 20 and caterpillar wheel 10 adopt the float grease seal formula, but also can adopt as required the central oiling formula.
The present invention also provides a kind of forward method of crawler crane, and crawler crane comprises the track unit of the above.Above-mentioned track frame all is equipped with in the track unit left and right sides, is wound with caterpillar block 3 on the periphery of track frame.When crawler crane walking and operation, internal box 1 top and outer case 2 against, the weight of crawler crane relies on the caterpillar wheel 20 of outer case 2 and the caterpillar wheel 10 of internal box 1 to support, and outer case 2 all contacts with ground with the caterpillar block of internal box 1 below, improves loading capacity of caterpillar crane.When crawler crane when turning to, hydraulic ram 24 stretches out, the piston rod of hydraulic ram 24 is resisted against internal box 1 top so that outer case 2 relative internal box 1 are picked up, thereby so that the caterpillar block 3 of outer case 2 belows breaks away from ground.Crawler crane relies on the caterpillar wheel 10 of internal box 1 bottom to support on the ground.Thereby improved the turning efficiency of crawler crane.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
