Abstract
The utility model discloses the special guideway device of a kind of hydraulic jack, comprise hydraulic jack guide bush, the position that hydraulic jack guide bush contacts with piston rod is provided with two annular grooves, the degree of depth of two annular grooves is 2mm, width is 16mm, center distance between two annular grooves is 42mm, and the distance of annular groove distance guide bush outermost edges is 10mm; In two annular grooves, be filled with nylon lining, between nylon lining and piston rod, scribble hydraulic oil, ensure its seamless slip or rotation.The utility model is by being directly mounted to nylon lining in guide bush, the effect supporting and ensure piston rod and cylinder barrel coaxality can be played, reduce the wearing and tearing of piston rod, play sealing protection effect, once there is oil leakage phenomenon, do not need to change guide bush, directly change the nylon lining inside guide bush, effectively can reduce maintenance cost, be applicable to all Leakages caused because oil hydraulic cylinder guide bush occurs wearing and tearing.
Description
Technical field:
The utility model relates to a kind of guideway special purpose device, particularly relates to a kind of runabout crane amplitude oil cylinder and prevents the special guideway device of the hydraulic jack of leakage of oil.
Background technique:
In the using process of 50T truck with crane, find that two luffing oil hydraulic cylinder heads often occur oil leakage phenomenon, by a complete set of seal ring of replacing luffing hydraulic jack, using effect is not good, still have oil leakage phenomenon, and frequent leakage of oil can accelerate the degree of wear of guideway and piston rod.How reducing the wearing and tearing of piston rod, improving the working life of oil hydraulic cylinder is the technical problem being badly in need of solving.
Model utility content:
The technical problem that the utility model solves is: provide a kind of hydraulic jack special guideway device, solve the problem of hydraulic jack leakage of oil, by installing nylon lining additional in guide bush, can play and support and ensure piston rod and cylinder barrel coaxality, reduce the wearing and tearing of piston rod, also play seal action simultaneously.
The technological scheme that the utility model is taked for technical solution problem is:
The special guideway device of a kind of hydraulic jack, comprise hydraulic jack guide bush, the position that described hydraulic jack guide bush contacts with piston rod is provided with two annular grooves, the degree of depth of described two annular grooves is 2mm, width is 16mm, the center distance of two annular grooves is 42mm, and annular groove outermost edge is 10mm apart from the distance of described hydraulic jack guide bush outermost edges; All nylon lining is filled with in described two annular grooves.
Hydraulic oil is scribbled, seamless slip or rotation between described nylon lining and piston rod.
For 50T truck with crane luffing oil hydraulic cylinder, add man-hour, remove the connection of amplitude oil cylinder upper one end, back out end cap and guide bush, extract piston rod out and remove piston, then guide bush car is gone out two grooves, then nylon lining is embedded in two grooves, load together with guide bush on piston rod, adding the size will noting rut groove man-hour will be consistent with the size of nylon lining again.
The utility model, by being directly mounted in guide bush by nylon lining, can play the effect supporting and ensure piston rod and cylinder barrel coaxality, reduces the wearing and tearing of piston rod, also plays seal action simultaneously.
The utility model, once there is oil leakage phenomenon, does not need to change guide bush, directly changes the nylon lining inside guide bush, effectively can reduce maintenance cost.
The utility model structure is simple, reasonable in design, has good use value and technological guidance's meaning, is applicable to all Leakages caused because oil hydraulic cylinder guide bush occurs wearing and tearing.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further explained and illustrate:
See Fig. 1, the special guideway device of a kind of hydraulic jack, comprise hydraulic jack guide bush 1, the position that hydraulic jack guide bush 1 contacts with piston rod 3 is provided with two annular grooves 2, the degree of depth of two annular grooves 2 is 2mm, width is 16mm, the center distance of two annular grooves 2 is 42mm, and annular groove outermost edge is 10mm apart from the distance of described hydraulic jack guide bush 1 outermost edges; All nylon lining is filled with in two annular grooves 2; Between nylon lining and piston rod 3, scribble hydraulic oil, ensure its seamless slip or rotation.
The utility model, by being directly mounted in guide bush 1 by nylon lining, can play the effect supporting and ensure piston rod 3 and cylinder barrel coaxality, reduces the wearing and tearing of piston rod 3, also plays seal action simultaneously; The utility model, once there is oil leakage phenomenon, does not need to change guide bush, directly changes the nylon lining inside guide bush, effectively can reduce maintenance cost; The utility model structure is simple, reasonable in design, is applicable to all Leakages caused because oil hydraulic cylinder guide bush occurs wearing and tearing.
