Description
Technical field
The utility model relates to a kind of novel crawler cranes, belong to crane machinery field.
Background technique
To meet requirement of the Larger Engineering Projects such as ocean engineering to lifting equipment, the functional requirement of crane is more and more
Sample, the crane for ship auxiliary lifting need to increase personnel's carrying function of marine requirement, and this adds increased associated members
Quantity.With the development of hoisting large-size, a series of problems during design, transport, dismounting etc. is brought, it is serious to restrict
The development of crawler crane, it would be highly desirable to which developer optimizes innovation.
The mast load assembly important as changing-breadth system, structure type and the bearing capacity of itself are to lifting equipment
Safety and ease of use have important influence.The mast structure form of crawler crane is generally the double limb knots of box
Structure, design has pulley block structure thereon, and the wirerope stretched out from main transformer width elevator bypasses mast top sheave, and twines by design multiplying power
It is wound on main transformer width pulley blocks, forms main changing-breadth system.In view of the dismounting convenience of associated member, and respond national road road transport
The defeated new call for handing over rule, in transport, main changing-breadth system is integrally transported.With the diversification of China project item demand, to shoe
Also diversification and the enlargement of the demand of belt lifter operating condition, and to will lead to associated member quantity corresponding for the increase of applying working condition
Increase, this will make limitation of the associated member in transport by the length, width and height and weight of road transport, and therefore, crawler type rises
Heavy-duty machine should guarantee the diversification of duty requirements and the enlargement of equipment in design, meet the requirement of transportation clearance again, and
How to solve this becomes the critical issue of crawler crane research and development to contradiction.
Lifting mechanism (or jib lubbing mechanism) mounting means generally used in industry at present includes following two mode.Such as figure
Shown in 1, one is lifting mechanism (or jib lubbing mechanism) to be arranged in turntable, limited by turntable bulk, therefore to turntable
Layout designs are more demanding.In view of the dismounting convenience of associated member, the lifting mechanism being arranged in turntable is needed in transport
It is integrally transported with turntable, host weight when will increase transport, and more demanding to each component hauled weight is associated with.Meanwhile turntable
Bulk limited by transportation clearance and hauled weight, it is impossible to it is unlimited to increase, and improve the material of used raw material,
Cost can be made to increase accordingly.As shown in Fig. 2, another kind is that lifting mechanism (or jib lubbing mechanism) is arranged on principal arm coxopodite arm,
It will receive the limitation in space and the mode that walks on the rope.Principal arm coxopodite arm configuration intensity is influenced by lifting performance, and cross-sectional sizes are transported
The layout of the limitation of size, structure can limit fall line mode, this three aspect all limits lifting mechanism (or luffing machine
Structure) rational deployment on principal arm coxopodite arm.
With the increase of crawler crane tonnage, the enlargement development of lifting components and the diversification of lifting demand, ring
It answers national road transport that rule is newly handed over to call and realizes that high efficient and reliable dismounts the vital task researched and developed at crawler crane.For
Crawler crane changing-breadth system dismounts the problem that the frequency is high, the period is long, the modulation conformity of changing-breadth system need to be considered comprehensively, to pass
Join component and carry out reasonable combination, to improve dismounting convenience and reliability.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of existing technologies, and provides one kind and is able to solve turntable
The problem of internal installation space limits alleviates the overweight pressure of host transport association part, while can also mitigate to principal arm coxopodite
The novel crawler crane of the limitation of arm configuration.
In order to solve the above technical problems, the technical solution adopted by the utility model is:
A kind of novel crawler crane, including creeper undercarriage are provided with turntable, principal arm on the creeper undercarriage
The lower end of coxopodite and mast and the turntable are hinged, and luffing pulley blocks and luffing elevator, the luffing are provided on the turntable
The lower end of pulley blocks and the turntable are hinged, and the upper end of the mast is provided with fixed pulley group, and variable-amplitude steel wire rope is from the luffing
Elevator is connected to the luffing pulley blocks by the fixed pulley group, and raising elevator, the raising volume are provided on the mast
The lower end for being connected with hoist rope is raised, the upper end of the hoist rope is connected with the arm end single-sheaved block on principal arm arm head.
The principal arm coxopodite is connected with the anti-hypsokinesis upper end of principal arm, is provided on the turntable and is used to support the anti-hypsokinesis of the principal arm
The limiting device of lower end.
The limiting device is L-type structure.
It is connected between the luffing pulley blocks and the turntable by pin shaft.
The raising elevator is located at following in the middle part of the mast.
The luffing elevator is located at the rear end of the turntable.
The utility model has the beneficial effects that the utility model breaches the traditional layout side of lifting mechanism (or jib lubbing mechanism)
Formula provides a kind of novel crawler crane, is arranged in the layout type on mast using by raising elevator, can effectively drop
The low limitation to turntable bulk and intensity, can be effectively reduced the hauled weight of turntable associated member, transport new hand over to meet
Rule require.For in terms of cantilever crane, which can be effectively reduced the limit of transportation clearance and hauled weight to principal arm coxopodite arm
System, and the limitation to principal arm coxopodite arm configuration intensity can be reduced, meet the needs of rationally fall line mode.In addition, the raising elevator
Layout type, allow to realize transport when with mast integrally transport, to improve the dismounting convenience of associated member.
