The utility model discloses fix the arm -tie at the cantilever crane in -plant transportation, avoided the arm -tie to warp and collide with, the special wooden case of unnecessary design only needs to increase by several arm -ties brackets, low cost, make full use of transports the space, reduces the cost of transportation, dismounting method reliable and simple only needs the manpower to accomplish.
Description
Technical field
This utility model relates to the arm-tie on a kind of crane, belongs to crane technical field.
Background technology
Crawler crane belongs to runabout crane, and arm-tie 1 is to connect jib 2 and mast 3(man-like shelf) structure, such as Fig. 1.Crawler crane transports with flat car after needing when distance transition to split jib 2, arm-tie 1, and arm-tie generally presses its different pattern length with the arm joint of corresponding length or with mast transport.The operating mode of crawler crane typically has multiple, and jib length has multiple combination mode, corresponding arm-tie also to have multiple combination mode.Along with the increase of tonnage, arm-tie quantity can increase, when arm-tie is more, it is impossible to when all transporting with jib or mast, and the means of transportation of residue arm-tie has just become problem.Existing means of transportation mainly has two kinds: one is by the vanning transport of residue arm-tie, the elongate form of arm-tie, needs design to be suitable for the elongated wooden case of arm-tie；Another kind is that arm-tie is naked to be put in transport vehicle by remaining.
Arm-tie to be avoided colliding with, deforming when transport as far as possible, otherwise can affect its serviceability.Colliding with of arm-tie surface is likely to result in the reduction of arm-tie intensity, and operationally, arm-tie bears huge pulling force, and once inefficacy can cause the serious consequence of car crash.Arm-tie is placed improper meeting and is caused the deformation of length direction, affects the dimensional accuracy of arm-tie.
Therefore, the mode of the transport arm-tie that both the above is conventional at present is respectively present following shortcoming:
1) during arm-tie vanning transport, arm-tie is not fixed easily travel position in wooden case, the most inevitably collides, and easily produces bigger defect of colliding with when road conditions are severe, both the serviceability of arm-tie had been affected, simultaneously because collide with and fall the phenomenon of paint and can affect the outward appearance of arm-tie.Additionally, due to the special wooden case of needs, also accordingly increase cost of transportation.
2) arm-tie is naked puts when transporting onboard, and arm-tie and miscellaneous part are easier to collide with, and the consequence caused is similar to previous bar.Further, since the naked degree of freedom put than vanning is transported of arm-tie is bigger, in addition to easily colliding with, the most easily it is deformed, affects the dimensional accuracy of arm-tie.
Utility model content
Technical problem to be solved in the utility model is the defect overcoming prior art, it is provided that a kind of built-in arm-tie transport structure.
For solving above-mentioned technical problem, this utility model provides a kind of built-in arm-tie transport structure, it is characterized in that, including at least one pair of the arm-tie bracket being arranged within jib, arm-tie bracket one end is welded on jib, and the other end has the opening that can accommodate arm-tie；When the two ends of arm-tie are placed in the opening of a pair arm-tie bracket accordingly, arm-tie is limited in the opening without departing from arm-tie bracket in a resistance de-portion.
Every pair of arm-tie bracket is along jib longitudinal direction correspondence spread configuration.
It is to be arranged on the bearing pin at arm-tie bracket openings and the split pin, jump ring or the back-up ring that are stuck in by bearing pin on arm-tie bracket that described resistance takes off portion.
It is bandage that described resistance takes off portion.
Described arm-tie bracket is carrying roller.
Openings of sizes on arm-tie bracket matches with the thickness of arm-tie, is just contained in the opening of arm-tie bracket when making arm-tie edge-on.
The beneficial effect that this utility model is reached:
1) arm-tie is fixed on jib inside transport, it is to avoid arm-tie deformation and colliding with.
2) special wooden case need not be designed, only need to increase several arm-tie bracket, with low cost.
3) make full use of transport space, reduce cost of transportation.
4) assembly and disassembly methods is simple, only needs manpower to complete.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.Following example are only used for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
Jib is a kind of space truss structure, take up room during transport bigger, the transport space of waste is more, this utility model is based on this, as shown in Figures 2 and 3, built-in arm-tie transport structure of the present utility model includes at least one pair of the arm-tie bracket 101 being arranged on along the longitudinal direction within jib 2, and it is internal that arm-tie bracket 101 one end is welded on jib 2, the other end has the opening that can accommodate arm-tie 1, and the arm-tie 1 that opening part can arrange bearing pin 102 and split pin 103 is placed in opening is fixed.After bearing pin 102 passes the outer end of arm-tie bracket 101 opening, split pin 103 lock.In other embodiments, split pin 103 can also use jump ring, back-up ring etc. to replace, and is limited to not fall off on the outer end of arm-tie bracket 101 opening by bearing pin 102.
Internal along longitudinally increasing arm-tie bracket 101 at jib, and use bearing pin 102 and split pin 103 to be fixed on arm-tie bracket 101 at arm-tie two ends, such as Fig. 2 and Fig. 3, so when transport, arm-tie is limited in the opening of arm-tie bracket 101 by bearing pin 102, it is to avoid the motion of radial direction, arm-tie bracket 101 limit the motion of longitudinal direction, arm-tie 1 just from colliding with and the arm-tie edge-on placement of holding, will not reduce its serviceability.Arm-tie is important primary structure member, and once function decreases can affect vehicle performance, and is susceptible to danger.Easily produce flexure when arm-tie keeps flat, as shown in Figure 4, thus affect its dimensional accuracy and intensity.So the depositing of arm-tie, travel position will remain side and put state, such as Fig. 5.It is preferred that the openings of sizes of arm-tie bracket 101 upper end matches with the thickness of arm-tie 1, can just be contained in the opening of arm-tie bracket 101 upper end when making arm-tie 1 edge-on.Bearing pin, split pin for being limited to by arm-tie 1 in the opening of arm-tie bracket 101 are standard component, easy for installation, it is prone to supplementary during disappearance, can also adopt in other embodiments and in other ways arm-tie 1 is limited in the opening of arm-tie bracket 101, such as the mode using bandage to fix.
The invention provides a kind of built-in arm-tie transport structure, take full advantage of the transport space of jib 2, save the cost of vanning transport, meanwhile, arm-tie 1 is fixed on jib 2 inside transport, it is to avoid arm-tie 1 deforms and collides with, and is effectively protected arm-tie.The present invention has only to, at jib interior welds several arm-tie bracket 101, add bearing pin, split pin, with low cost.
When using this transport structure of the present utility model, placement and the taking-up of arm-tie are the most more convenient, owing to arm-tie is built in jib, it is impossible to use suspender to be placed or taken out, and the weight of arm-tie is generally not capable of too big, and two people can lift.By two workmans arm-tie can be lifted when transport and put to the arm-tie bracket within jib, then with bearing pin, split pin, arm-tie two ends are separately fixed at arm-tie bracket.When dismantling in job site, bearing pin, split pin are taken off and can be carried away use.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; on the premise of without departing from this utility model know-why; can also make some improvement and deformation, these improve and deformation also should be regarded as protection domain of the present utility model.
