Description
Technical field
The utility model belongs to crane field, specially a kind of crawler telescopic arm hoisting machine arm rest supporting device.
Background technique
Crane is capable of more movement hoisting machineries of vertical-lift and horizontal carrying heavy goods in a certain range, in order to realize
It is mobile, usually hoisting operation is partially contained on crawler body, while in order to realize that enhanced feature and covering are as much as possible
Region, crane mostly use telescopic jib structure, when hoisting operation is completed and crane carries out remote transition, arm
Frame needs to be retracted on arm rest supporting device；But conventional support device is that steel frame construction causes if cantilever crane retraction speed is too fast
Support device and impact force in cantilever crane contact process are excessive, and support device or car body is be easy to cause to damage.
Utility model content
The purpose of this utility model is in view of the above problems, providing a kind of crawler telescopic arm hoisting machine cantilever support dress
It sets, impact force when cantilever crane is contacted with support device can be buffered, it is ensured that equipment uses safe.
In order to achieve the above object, the technical solution adopted in the utility model is: it includes pedestal, is provided in the pedestal
The piston rod of oil cylinder, the oil cylinder upwardly extends and stretches out pedestal upper end, and the piston rod upper end of the oil cylinder is connect with bottom plate, institute
It states floor level setting and bottom plate upper end array is provided with damping spring, the damping spring is vertically arranged and upper end and support board
Lower end connection, the support board left and right sides are hinged with fixed plate；The pedestal upper end is provided with baffle in fixed plate two sides.
Further, the fixed plate is L-shaped.
Further, fixed plate opposite side in two sides is provided with buffer spring, and the buffer spring is connect with head clamp, and two
The head clamp of side is oppositely arranged.
Further, the pedestal upper end is provided with damper below bottom plate.
The utility model has the beneficial effects that oil cylinder pushing bottom plate connects when cantilever crane work is completed to be retracted in support device
It is raised above with support board, to hold cantilever crane in advance, reduces partial buffer power, after holding, the piston rod of oil cylinder bounces back, so that carrying
Object plate synchronous with cantilever crane can decline, it is ensured that cantilever crane can normally be withdrawn.
1, during support board decline, baffle is contacted with fixed plate, so that fixed plate is around hinged spot wobble, by cantilever crane card
Between the fixed plate of two sides, cantilever crane is avoided to shake.
2, array is provided with damping spring between bottom plate and support board, and cantilever crane on the one hand can be buffered using damping spring and is carried
Impact force when object plate contacts, on the other hand makes support board during cantilever crane is held in rising, support board being capable of follower arm
The angle of frame is adjusted.
Detailed description of the invention
Fig. 1 is the utility model status diagram when cantilever crane recycles.
Fig. 2 is that support board jacks up status diagram.
Label character described in figure indicates are as follows: 1, pedestal；2, oil cylinder；3, bottom plate；4, damping spring；5, support board；6, solid
Fixed board；7, baffle；8, buffer spring；9, head clamp；10, damper；11, cantilever crane.
Specific embodiment
In order to enable those skilled in the art to better understand the technical solutions of the present invention, with reference to the accompanying drawing to this reality
Be described in detail with novel, the description of this part be only it is exemplary and explanatory, should not be to the protection scope of the utility model
There is any restriction effect.
As Figure 1-Figure 2, the specific structure of the utility model are as follows: it includes being set on crawler telescopic arm hoisting machine
Pedestal 1, be provided with oil cylinder 2 in the pedestal 1, the piston rod of the oil cylinder 2 upwardly extends and stretch out 1 upper end of pedestal, described
The piston rod upper end of oil cylinder 2 is connect with bottom plate 3, and the bottom plate 3 is horizontally disposed and 3 upper end array of bottom plate is provided with damping spring 4,
The damping spring 4 is vertically arranged and upper end is connect with 5 lower end of support board, is hinged with fixed plate at left and right sides of the support board 5
6；1 upper end of pedestal is provided with baffle 7 in 6 two sides of fixed plate, and 7 upper surface of baffle can connect with 6 lateral surface of fixed plate
Touching, so that fixed plate 6 is capable of fixing cantilever crane 11.
Preferably, in order to preferably fix cantilever crane 11, the fixed plate 6 is L-shaped, when so as to entirely protecting
Cantilever crane 11.
Preferably, fixed plate 6 opposite side in two sides is provided with buffer spring 8, and the buffer spring 8 is connect with head clamp 9,
The head clamp 9 of two sides is oppositely arranged, and when support board decline, fixed plate 6 is swung to fix cantilever crane 11, passes through buffer spring 8
Flexible can be avoided block and position can not be completely returned to and fixed plate 6 is contacted with cantilever crane 11 during support board decline
When, lead to 11 concave side wall of cantilever crane.
Preferably, 1 upper end of pedestal is provided with damper 10 below bottom plate 3, to improve safety.
When specifically used: during cantilever crane 11 is withdrawn, oil cylinder 2 jacks up support board 5, so that support board 5 holds cantilever crane in advance
11, then oil cylinder 2 pulls support board 5 that it is made to follow the synchronous decline of cantilever crane 11, and during decline, baffle 7 withstands 6 outside of fixed plate
Face, so that hinged spot wobble of the fixed plate 6 around itself and support board 5, to fix cantilever crane 11；When needing using cantilever crane 11, oil
Cylinder 2 jacks up support board 5, so that support board 5 follows cantilever crane 11 is synchronous to rise, when 5 lower end surface of support board is higher than 7 upper surface of baffle
When, support board 5 stops rising, and cantilever crane 11 continues to rise under the drive of crawler telescopic arm hoisting machine hydraulic device at this time, top
Fixed plate 6 is opened, to start to work normally.
