Abstract
The utility model relates to a multi-stage anti-rotation liquid-gas cylinder, comprising a cylinder jacket, which has a plurality of sleevedly connected piston stages inside and a plurality of positioning guide bar stages outside; each positioning guide pipe stage having a linking plate at the outer end for connection with outer end of corresponding piston rod stage. The utility model equips, outside the multi-stage liquid-gas cylinder, positioning guide pipes with the same stage quantities as the cylinder, so when the piston rod does reciprocating movements, the positioning guide pipes fixed outside the cylinder jacket, under the effect of the linking plates, will restrain each piston stage to make reciprocal linear movements at a fixed point of the cylinder jacket, thereby effectively preventing the rotation of the piston rod and providing aloft work with more safety assurance.
Description
[technical field]
The utility model relates to a kind of liquid gas pressure cylinder, relates in particular to a kind of multistage anti-rotation liquid gas pressure cylinder that is provided with positioning device.
[background technique]
The liquid gas pressure cylinder is widely used in engineering machinery field; its kind and model are a lot; multistage liquid gas pressure cylinder is the liquid gas pressure element in a kind of lowering or hoisting gear that is widely used in high-lift operation, because this kind liquid gas pressure cylinder stroke is long, load area is big again; suffered external force influence is also big; as the influence of wind-force, when liquid gas pressure cylinder and load moved up and down, the piston rod of liquid gas pressure cylinder turn occurred through regular meeting; bring danger for the high-lift operation personnel, also influence construction speed simultaneously.
[model utility content]
In order to overcome the above-mentioned shortcoming of prior art, it is a kind of at the housing department setting of the multistage liquid gas pressure cylinder positioning catheter identical with its progression that the utility model provides, by corresponding joining plate piston rod is connected accordingly with positioning catheter, just can effectively stop the rotation of piston rod, play the effect of steady load, make the safer multistage anti-rotation liquid gas pressure cylinder of high-lift operation.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of multistage anti-rotation liquid gas pressure cylinder, comprise cylinder barrel, be provided with the multi-level piston bar of socket in the described cylinder barrel, described cylinder barrel outside is provided with multistage location guide, outer end at every grade of positioning catheter is provided with joining plate, is connected with the piston rod outer end of corresponding stage by this joining plate.
The progression of described positioning catheter is identical with the progression of piston rod.
Described positioning catheter level and inter-stage are telescopic socket layer by layer.
Described joining plate quantity is identical with the progression of piston rod, positioning catheter.
The beneficial effects of the utility model are: at the cylinder barrel outer installment of the multistage liquid gas pressure cylinder positioning catheter identical with its progression, when piston rod is made fore and aft motion, under the interlock effect of joining plate, the positioning catheter that is fixed on the cylinder barrel outside just can make each grade piston rod do reciprocating linear motion on the immovable point of cylinder barrel, stoped the turn of piston rod effectively, safer when making high-lift operation.
[description of drawings]
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-cylinder barrel, 2-piston rod, 3-positioning catheter, 4-joining plate.
[embodiment]
Referring to Fig. 1, a kind of multistage anti-rotation liquid gas pressure cylinder, comprise cylinder barrel 1, in cylinder barrel 1, be socketed with multi-level piston bar 2, the outside is provided with the location guide 3 identical with piston rod 2 progression, be provided with joining plate 4 in the outer end of each grade positioning catheter 3, be connected by the outer end of joining plate 3 with corresponding stage piston rod 2, when piston rod 2 is made fore and aft motion, under the interlock effect of joining plate 4, the positioning catheter 3 that is fixed on cylinder barrel 1 outside just can make each grade piston rod 2 do reciprocating linear motion on the immovable point of cylinder barrel 1, has stoped the turn of piston rod 2 effectively, bring the unfavorable factor of turn also to be resolved by external force, safer when making high-lift operation.
Claims (4)
1, a kind of multistage anti-rotation liquid gas pressure cylinder, comprise cylinder barrel, it is characterized in that: be provided with the multi-level piston bar of socket in the described cylinder barrel, described cylinder barrel outside is provided with multistage location guide, outer end at every grade of positioning catheter is provided with joining plate, is connected with the piston rod outer end of corresponding stage by this joining plate.
