Description
Technical field
The utility model relates to a kind of weight-lifting equipment, particularly relates to a kind of shock-absorbing folding arm crane.
Background technology
Shock-absorbing folding arm crane, also known as folding-jib loop wheel machine, is a kind of conventional weight-lifting equipment.
In prior art, be in the Chinese utility model patent of 201420798413.4, disclose a kind of multi-functional shock-absorbing folding arm crane in the patent No., it comprises shock-absorbing folding arm crane car body, two joint arms are provided with winch, winch is taken turns by the HM Hydraulic Motor be fixed on two joint arms and elevator and is formed, elevator wheel is provided with one end and fixes and be wrapped in the steel rope on elevator wheel, the front ends of four joint arms are equipped with fixed pulley mechanism surely, and the fixed pulley that the other end of steel rope walks around fixed pulley mechanism changes direction rearward end and is provided with suspension hook.It both may be used for lifting, and can also grow distance traction and pull, using function is more, rescue ability and rescue better effects if.The using function of shock-absorbing folding arm crane and alerting ability are enhanced, for disaster unit provide strong at a distance, space operation ability on a large scale; Can greatly promote rescue efficiency, for the rescue reducing national wealth loss and the wounded is played a positive role.
But, shock-absorbing folding arm crane in above-mentioned patent, its crossbeam position is more fixing comparatively speaking, when needing to adjust beam height, by HM Hydraulic Motor, crossbeam vertical lift on column is regulated, this regulative mode makes the interaction force between column and crossbeam comparatively large, easily causes wearing and tearing after long term.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is that providing a kind of can reduce the shock-absorbing folding arm crane worn and torn between crossbeam and column.
For achieving the above object, the utility model provides following technical scheme: a kind of shock-absorbing folding arm crane, include chassis, the bottom on described chassis is provided with multiple universal caster wheel, a retractable long pin is connected with in side, described chassis, the bottom of described long pin is also provided with universal caster wheel, wherein, column is fixed with above described chassis, described column top is fixed with a crossbeam, described crossbeam inner hollow is formed with passage, described passage is formed with opening in one end of described crossbeam, be fixed with slidably in described passage in one and manage, and described opening part is provided with the stop gear that the end that can limit described interior pipe skids off described passage,
Described interior pipe is connected with suspension hook;
Also include strut bar, described strut bar one end can be connected on described column rotationally, and the other end is resisted against on described chassis, is connected with control lever in described strut bar side;
Also include driver train, be provided in the propulsive effort slided in described passage for inside pipe; The connecting portion of described crossbeam and column is provided with damping damper.
As improvement of the present utility model, described driver train is oil pump, and described oil pump has piston rod, and described piston rod is connected with described interior pipe.
As preferably of the present utility model, described interior pipe one end offers mounting hole, is equipped with chain, described chain is hung with suspension hook in described mounting hole.
Compared with prior art, the utility model has the advantage of: by connecting a strut bar on column, this strut bar one end is rotatably connected on column, the other end is resisted against on chassis, the structure of a similar ladder, the angle of inclination of adjusting post so just can be come by this strut bar, crossbeam is fixed with at the top of column, when the angle of inclination of column changes, correspondingly, horizontal depth of beam also there occurs change, and in this course, the position of column and crossbeam remains fixing, this also just reduces wearing and tearing between the two, extend its work life, in addition, a damping damper is set between crossbeam and column, when chassis is moved, column will certainly be caused to shake, and crossbeam is entirely by supporting its total weight with the connecting portion of column, if crossbeam resonates with column, then easily cause it to damage, and the resonance that a damping damper effectively can eliminate crossbeam is set.

Fig. 2 is the lateral plan of shock-absorbing folding arm crane in the utility model embodiment;
Fig. 3 is the receipts overlapping state schematic diagram of shock-absorbing folding arm crane in the utility model embodiment.
Detailed description of the invention
With reference to Fig. 1-Fig. 3, the embodiment of shock-absorbing folding arm crane in the utility model is described further.
As shown in figures 1 and 3, a kind of shock-absorbing folding arm crane, includes corrosion-resistant steel chassis 1, and the edge on this chassis is all arranged with anti-collision rubber bar, can effectively reduce in unexpected collision situation, the damage that external impact force causes chassis itself.
The bottom on described chassis is provided with multiple universal caster wheel 2, the quantity of universal caster wheel is determined according to the size of shock-absorbing folding arm crane, be generally 4-16, all from being furnished with brake system (such as brake facing or brake lever) on each universal caster wheel, the benefit of universal caster wheel is adopted to be the flexible rotating that can utilize universal caster wheel, the convenient moving direction regulating shock-absorbing folding arm crane, makes it turn to more flexible.
In addition, a retractable long pin 3 is connected with in side, described chassis, the bottom of described long pin is also provided with universal caster wheel 2, wherein, column 4 is fixed with above described chassis, this column one end is actually and is rotatably mounted on chassis, and chassis is provided with dwang, and one end of this column is set on dwang.
As shown in Figure 1, described column top is fixed with a crossbeam 5, and the connecting portion of described crossbeam and column is provided with damping damper 10.Described crossbeam inner hollow is formed with passage (not shown), described passage is formed with opening in one end of described crossbeam, pipe 6 in one is fixed with slidably in described passage, mentioned here slidably specifically referring to is provided with chute in vias inner walls, interior pipe is slidably connected in chute, can slidably reciprocate in channel interior thus, and then adjusting lift hook relative position in the X-axis direction.Skid off from crossbeam completely to prevent interior pipe, cause danger, the opening part of described passage is provided with the stop gear 51 that the end that can limit described interior pipe skids off described passage, and above-mentioned stop gear can be limiting stopper, also can be the elastic damper with certain buffering effect;
