Abstract
Include jib tip structure, hoist rope, guide wheel group and raising suspension hook on crane arm the utility model is related to a kind of locomotive crane arm head pulley mechanism;Further include fixed pulley group and running block;The fixed pulley group is mounted on the top of jib tip structure, and the running block is mounted in raising suspension hook, and raising suspension hook is connect around guide wheel group, fixed pulley group and running block with jib tip structure successively by hoist rope.To sum up, in the case that the utility model suspender and steel wire rope when ensuring jib tip structure luffing is not related to arm soma so that raising suspension hook highest from the ground, and then meet the requirement of operation, there is extensive market prospects and use value.
Description
Technical field
The utility model is related to pulley mechanism more particularly to a kind of locomotive crane arm head pulley mechanisms, belong to engineering machine
Tool equipment technical field.
Background technology
Locomotive crane is a kind of runabout crane.With the development of railway construction, new line construction and old line are being carried out
During maintaining, it is required for carrying out the lifting and transhipment of material by the operation of locomotive crane.Moreover, with market
Medium-and-large-sizedization is tended to the function of product, and has the limitation of some safety clearances in operation process.
Such as in raising operation, suspender is limited because of environment limit reason by the work in height, and often again
Ask suspender higher from the ground in operation, and existing arm head pulley mechanism, when in use, in order to meet arm support at luffing big angle
The operation of degree, fixed pulley group are in below arm, and suspender is relatively low from the ground, cannot be satisfied operation needs.It is difficult to meet and highly want
It asks.
Utility model content
In view of the above-mentioned problems of the prior art, the utility model provides a kind of locomotive crane arm head pulley mechanism,
The suspender lower space that bigger is provided, to facilitate the lifting and transhipment of cargo.
To achieve the goals above, the utility model includes the jib tip structure being mounted on crane arm, hoist rope, leads
To wheel group and raising suspension hook;Further include fixed pulley group and running block;The fixed pulley group is mounted on the top of jib tip structure,
The running block is mounted in raising suspension hook, and raising suspension hook bypasses guide wheel group, fixed pulley successively by hoist rope
Group and running block are connect with jib tip structure.
Further, jib tip structure design angle is matched with change angle.
Further, fixed pulley group is identical with running block size.
Further, the center of fixed pulley group and running block is on same vertical plane.
Operation principle:When hoist rope carries out folding and unfolding campaign, by effective guiding of guide wheel group, pass through fixed pulley group
With the effect of 4, running block, make raising suspension hook carry out raising and lowering, wherein jib tip structure upper design have running block and
The space of hanging hook, when rising to extreme position, it is ensured that raising suspension hook highest, and jib tip structure design angle from the ground
Degree is matched with change angle, it is ensured that in luffing, suspender is not related to steel wire rope with arm soma.
To sum up, in the case that the utility model suspender and steel wire rope when ensuring jib tip structure luffing is not related to arm soma,
Make raising suspension hook highest from the ground, and then meet the requirement of operation, there is extensive market prospects and use value.
Description of the drawings
Attached drawing 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model includes the jib tip structure 6, hoist rope 1, directive wheel being mounted on crane arm 7
Group 2 and raising suspension hook 5;Further include fixed pulley group 3 and running block 4;The fixed pulley group 3 is mounted on the top of jib tip structure 6
Portion, the running block 4 are mounted in raising suspension hook 5, and the raising suspension hook 5 is bypassed by hoist rope 1 and led successively
It is connect to wheel group 2, fixed pulley group 3 and running block 4 with jib tip structure 6.
It is further improved as the utility model, 6 design angle of jib tip structure is matched with change angle.
It is further improved as the utility model, fixed pulley group 3 is identical with 4 size of running block.
It is further improved as the utility model, the center of fixed pulley group 3 and running block 4 is on same vertical plane.
When hoist rope 1 carries out folding and unfolding campaign, by effective guiding of guide wheel group 2, pass through fixed pulley group 3 and dynamic cunning
The effect of wheel group 4 makes raising suspension hook 5 carry out raising and lowering, wherein 6 upper design of jib tip structure has running block 4 and hanging
The space of hook 5, when rising to extreme position, it is ensured that the highest, and the design of jib tip structure 6 angle from the ground of raising suspension hook 5
Degree is matched with change angle, it is ensured that in luffing, suspender is not related to hoist rope 1 with arm soma.
To sum up, in the case that the utility model suspender and steel wire rope when ensuring jib tip structure luffing is not related to arm soma,
Make raising suspension hook highest from the ground, and then meet the requirement of operation, there is extensive market prospects and use value.
