Description
Technical field
The utility model relates to engineering machinery field, particularly relates to a kind of crawler belt hanging structure for wheel crane and wheel crane.
Background technology
The advantages such as wheel crane is a kind of Full Rotary hoisting crane hoisting operation part be arranged on special chassis, has maneuverability, and transition is convenient.Wheel crane is the important component part of crane facility, mainly comprises car hosit, the full product such as Terrain Cranes, rough terrain wheeled crane.There is the advantages such as manoevreability is good, transfer is rapid, operation is efficient; But portioned product (as car hosit) must adopt supporting leg to support when working, can not load, also be not suitable for working on soft or muddy place, portioned product (as rough terrain wheeled crane) is although can adopt Tire support operation, band year traveling, but the load-carrying capacity due to tire, vehicle bridge limits and grounding pressure is larger, require higher to surface condition, often performance is lower.
Crawler crane is a kind of swing arm rotary crane hoisting operation part be arranged on crawler body, and its walking relies on crawler attachment, and ground contact area is large, crossing ability is good, strong adaptability, can be with and carry walking, but due to its structural limitations, the damage of crawler belt road pavement is comparatively large, traveling of can not setting out on a journey.And its speed of travel is slow, transfer building site needs to carry out dismounting, and by other vehicle conveyings, when arriving another one Active workings, need to ressemble, operating efficiency is low, traffic cost is high, and range of use is little, and limitation is larger.
In prior art, have and increased a set of detouchable caterpillar belt structure on existing wheel crane, enable wheel crane be quickly converted to a crawler crane, meet the lifting operation requirement under different pavement conditions, expand product range of use, realize the technical scheme of a tractor serves several purposes.
As shown in Fig. 1 (a), Fig. 1 (b), for in prior art, wheel crane increases wherein a kind of technical scheme of crawler attachment, it is by the transmission that adopt cordwood method increase by first connecting device 2 ', second connecting device 3 ' and connecting cross beam 4 ' realizable force upper on the chassis 1 ' of wheel crane, use crawler crane universal tracked 5 ' connects, and realizes the conversion of wheel crane and crawler crane.
The specific implementation process of technique scheme is as follows:
1) as shown in Figure 2, by auxiliary cylinder 6 ', the first connecting device 2 ' is promoted to the seat ring bottom surface on chassis 1 ', the bolt connecting hole on the first connecting device 2 ' is alignd with the bolt connecting hole on seat ring, and then is fixed by bolt.
2) as shown in Figure 3, use auxiliary cylinder 6 ' to be promoted by the second connecting device 3 ', make connecting bore 31 ' on the second connecting device 3 ' and the connecting bore 21 ' centering of the first connecting device 2 ', then fixed by the realization of locking oil cylinder pushing locking shaft.
3) as shown in Figure 4, connecting cross beam 4 ' is connected by bolt with the second connecting device 3 ', and so far, the structure of connecting cross beam 4 ' is identical with the crossbeam of conventional tracks hoisting crane with position.
4) as shown in Figure 5, connecting cross beam 4 ' and the linked vector graph of crawler belt 5 ' adopt the conventional linked vector graph of crawler crane to be connected, and so far, complete the conversion of wheel crane to crawler crane.
In technique scheme, after the vehicle frame of wheel crane and the first connecting device 2 ', the second connecting device 3 ' have assembled with connecting cross beam 4 ', make the structure of connecting cross beam 4 ' identical with conventional tracks hoisting crane with position, conveniently crawler crane can be installed by the installation that the step of crawler belt completes crawler belt.Wherein the first connecting device 2 ' and the second connecting device 3 ' also can make integral type, because with carriage bolt connection disassembling difficulty, generally do not dismantle when wheel crane state, make split type weight of equipment when effectively can reduce wheel crane travelling position, improve driveability.
, there is its own shortcomings in the above-mentioned technical scheme increasing a set of detouchable caterpillar belt structure on existing wheel crane:
