Description
Technical field
The utility model is related to crane field, and in particular to a kind of adjustable crane of beam height.
Background technology
Movable type gantry crane includes crossbeam, is vertically fixed in the vertical pillar on the downside of the beam-end, and
It is located at the inclined strut of the vertical pillar front and rear sides respectively.Crossbeam is provided with the dolly that can be moved back and forth along crossbeam.Under inclined strut
End is provided with roller, when gantry is moved at delivery thing to be shipped, and gantry stops movement.Now, dolly is put down
Goods is hooked, then goods is lifted to lorry.Conventionally, as the height of crane transverse beam immobilizes,
When in face of high capacity waggon（It is highly larger）, the boot height difference of beam height and high capacity waggon is little so that lifting work
Control operation inconvenience.
The content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of adjustable crane of beam height, its
Oneself height can be adjusted, and can adapt in the different high capacity waggon of height.
In order to solve the above-mentioned technical problem, the technical scheme that the utility model is used is：
The utility model provides a kind of adjustable crane of beam height, including crossbeam, is vertically fixed in the crossbeam
Vertical pillar on the downside of end, and it is located at the inclined strut of the vertical pillar front and rear sides, the upper end of two inclined struts respectively
Guide sleeve is connected with, the vertical pillar is slideably arranged in the guide sleeve；The lateral wall of the guide sleeve is connected with drive
Hydrodynamic cylinder pressure, the driving piston rod end of the driving hydraulic cylinder is fixed in the upper end of the vertical pillar；On the outside of the guide sleeve
Wall is also connected with bounce cylinder, and the bounce cylinder includes cylinder body, and is slidably arranged in the slow of the cylinder body
Piston rod is rushed, the end of the damper piston bar corresponds to the downside of the beam-end.
Specifically, the driving hydraulic cylinder is on the inside of the guide sleeve, and the bounce cylinder is outside the guide sleeve
Side.
Specifically, the inner hollow of the damper piston bar, and being connected with the inside of the cylinder；The damper piston bar
Side wall offers air inlet, and the end that the damper piston bar is located in the cylinder is provided with gas outlet.
Specifically, the lateral wall of part of the damper piston bar in the cylinder is arranged with sealing ring.
The beneficial effects of the utility model are：
Driving hydraulic cylinder can drive crossbeam to move up and down to suitable position, to be adapted to highly different large-scale goods
Car.When driving hydraulic cylinder drives crossbeam to be moved to crossbeam down close to guide sleeve（Vertical pillar is oppositely oriented set and moved down）,
The downside of beam-end can be contradicted in the end of damper piston bar, due to inside bounce cylinder filled with gases at high pressure so that buffering
Piston rod plays cushioning effect to the crossbeam moved down, it is to avoid crossbeam and the active force that guide sleeve is mutually touched are excessive.Thus, buffering
Cylinder plays a part of buffering, protection crossbeam, guide sleeve.
Brief description of the drawings
Fig. 1 is the stereogram of the adjustable crane of beam height of the present utility model；
Fig. 2 is another stereogram of the adjustable crane of beam height of the present utility model, wherein driving piston rod office
Portion stretches out in driving hydraulic cylinder；
Fig. 3 is half Section View of the utility model bounce cylinder therein.
Reference is in figure：
1. crossbeam, 2. vertical pillars, 3. inclined struts, 4. guide sleeves, 5. driving hydraulic cylinders,
51. drive piston rod, 6. bounce cylinders, 61. cylinder bodies, 62. damper piston bars,
621. air inlets, 622. gas outlets, 623. sealing rings.
Embodiment
Further illustrate embodiment of the present utility model below in conjunction with the accompanying drawings.
See Fig. 1 to Fig. 3, the adjustable crane of a kind of beam height that the present embodiment is provided, including crossbeam 1, it is vertically solid
The vertical pillar 2 on the downside of the end of crossbeam 1 is connected to, and is located at the inclined strut 3 of the vertical front and rear sides of pillar 2 respectively.Two inclined struts 3
Upper end be connected with guide sleeve 4, vertical pillar 2 is slideably arranged in guide sleeve 4.The lateral wall of guide sleeve 4 is connected with driving
Hydraulic cylinder 5, driving piston rod 51 end of driving hydraulic cylinder 5 is fixed in the upper end of vertical pillar 2.The lateral wall of guide sleeve 4 is also affixed
There is bounce cylinder 6, bounce cylinder 6 includes cylinder body 61, and is slidably arranged in the damper piston bar 62 of cylinder body 61.
The end of damper piston bar 62 corresponds to the downside of the end of crossbeam 1.Driving hydraulic cylinder 5 can drive crossbeam 1 to move up and down to conjunction
Suitable position, to be adapted to highly different high capacity waggons.When driving hydraulic cylinder 5 drives crossbeam 1, that crossbeam 1 is moved to down is close
During guide sleeve 4（Vertical pillar 2 is oppositely oriented set 4 and moved down）, the downside of the end of crossbeam 1 can be contradicted at the end of damper piston bar 62
End, due to inside bounce cylinder 6 filled with gases at high pressure so that the crossbeam 1 that 62 pairs of damper piston bar is moved down plays cushioning effect, keeps away
It is excessive with active force that guide sleeve 4 is mutually touched to exempt from crossbeam 1.Thus, bounce cylinder 6 plays buffering, protection crossbeam 1, guide sleeve 4
Effect.
Specifically, driving hydraulic cylinder 5 is located at the inner side of guide sleeve 4, and bounce cylinder 6 is located at the outside of guide sleeve 4, due to driving liquid
Cylinder pressure 5 and bounce cylinder 6 are placed in the both sides of guide sleeve 4 so that when vertical pillar 2 is close to guide sleeve 4, vertical pillar 2 it is inside and outside
Side stress balance.
Specifically, the inner hollow of damper piston bar 62, and connected with the inside of cylinder.The side wall of damper piston bar 62 is opened up
There is air inlet 621, the end that damper piston bar 62 is located in cylinder is provided with gas outlet 622.
Specifically, the lateral wall of part of the damper piston bar 62 in cylinder is arranged with sealing ring 623.
Above disclosed is only preferred embodiment of the present utility model, can not limit this practicality with this certainly new
The interest field of type, therefore the equivalent variations made according to present utility model application the scope of the claims, still belong to the utility model and are covered
Scope.
