Description
Technical field
The utility model relates to a kind of position regulator, relates in particular to a kind of hand-hydraulic space adjuster that is applicable to plain bolt fastener sleeper that location of rail is finely tuned of being used in the railway maintenance process.
Background technology
Along with the speed-raising of domestic railway passenger train and the construction of high speed passenger dedicated railway, the allowable variation of railway track gauge acceptance criteria has all been made respective specified, deviate reduces greatly, thereby newly-built circuit and the worker routine servicing maintenance of being engaged in proposed higher technical requirements, the gauge adjustment is exactly worker's one of related operation of routine servicing maintenance of being engaged in.
The double thread rod member commonly used of gauge adjustment in the early time is across on two rail of circuit, with the side rail benchmark that fixes, unclamp the sleeper fastening of opposite side, manually directly pull the double end sleeve nut at rod member middle part, rod member is elongated or shortened, gauge is adjusted purpose to reach.The operation of this kind gauge method of adjustment is cumbersome, efficient is low, labour intensity is big, and brings traffic safety hidden danger.
A kind of single track hydraulic pressure device that changes its course is disclosed in Chinese utility model patent 200720100336.6, its structure comprises base, is located at plunger displacement pump and fuel tank on the base, at a distolateral plunger and the plunger cylinder of also being provided with of base, plunger displacement pump communicates by pipeline road with plunger cylinder.This structure change its course device before being used for gauge adjusted, also need base is fixed on the sleeper bolt by nut, operating speed is slow.In addition, plunger displacement pump and fuel tank divide and are arranged, and are connected with tommy bar on the plunger displacement pump, push tommy bar after, plunger displacement pump can reach the outside of plunger cylinder by the hydraulic oil actuation plunger.The device that changes its course of this structure is because plunger displacement pump and fuel tank branch are arranged, and whole structural compactness is poor, volume big, Heavy Weight, inconvenience carry.And, also need the pipeline road that both are communicated is set between plunger displacement pump and the fuel tank, cause the cost of production height.
Summary of the invention
For overcoming the existing above-mentioned defective that is had when the gauge of railway track is adjusted operation, the technical problem that the utility model need solve: a kind of hand-hydraulic space adjuster that is applicable to plain bolt fastener sleeper is provided, and it has advantage simple in structure, easy and simple to handle, that operating speed is fast.
Another technical problem that the utility model need solve: provide a kind of structural compactness good, be beneficial to the hand-hydraulic space adjuster that is applicable to plain bolt fastener sleeper that carries.
For solveing the technical problem, the technical measures that the utility model is taked: a kind of hand-hydraulic space adjuster that is applicable to plain bolt fastener sleeper, comprise base, be located at plunger displacement pump and fuel tank on the base, base is provided with plunger cylinder, be provided with the plunger that stretches out its outside in the plunger cylinder, communicate by pipeline road between plunger cylinder and the plunger displacement pump, it is characterized in that, the bottom surface of a relative end with plunger is provided with outstanding being used to and is connected to convex body on the sleeper notch lateral surface on the base, on the described base near a distolateral prong that is used to be plugged on rail foot that is provided with of plunger.Described plunger is parallel to base, and the upper end of plunger displacement pump is used for linking with man-operated mechanism.When utilizing this space adjuster that the gauge of rail is adjusted, need unclamp the sleeper bolt nut earlier and take out fastener, base is shelved on the position in the rail inboard or the outside, convex body on the base contacts with the lateral surface of the sleeper notch in the rail inboard or the outside, and the prong position of base is plugged into the bottom of rail.By the operator actuation mechanism, man-operated mechanism can drive plunger displacement pump work, the hydraulic oil that plunger displacement pump drives in the fuel tank enters in the plunger cylinder, plunger is stretched out towards the outside of plunger cylinder, clamping qualification effect at described convex body and sleeper notch lateral surface, and under the qualification effect of rail to described prong, the end of plunger withstand on the waist of rail and promote rail reposefully occurrence positions move, the perk phenomenon can not take place in rail base in moving process, is convenient to the gauge adjustment and steadily successfully carries out.
For improving the integrally-built compactedness of this hand-hydraulic space adjuster, described plunger displacement pump is arranged in the fuel tank, and the upper end of plunger displacement pump reaches the fuel tank end face outside.The upper end of plunger displacement pump can be directly and man-operated mechanism be hinged together directly drive plunger displacement pump work during the man-operated mechanism action.Plunger displacement pump is arranged on the structural compactness that can effectively improve the hand-hydraulic space adjuster in the oil pump, reduced the size of base, plunger displacement pump directly is immersed in the interior hydraulic oil of fuel tank, can offer fuel feed hole on the plunger displacement pump and plunger displacement pump is communicated with fuel tank internal, pipeline road need be set between them.This hand-hydraulic space adjuster volume is little, in light weight, is beneficial to and carries.
As preferably, described pipeline road is located in the base, has further improved integrally-built compactedness.
As preferably, be respectively equipped with oil return valve and overflow valve on the described pipeline road, oil return valve and overflow valve branch are listed in the relative both sides of base.The oil return valve that is provided with can make the hydraulic oil that enters in the plunger cylinder be back in the fuel tank after operation finishes.
As preferably, be provided with between described plunger and the plunger cylinder and make the automatically reset resetting-mechanism of plunger.After described oil return valve was opened, under the effect of this resetting-mechanism, plunger can retract in the plunger cylinder automatically, for operation next time facilitates.
As preferably, described plunger and plunger cylinder are two covers, are arranged on the same side of base to their horizontal intervals.They are two covers, have improved the stressing conditions of rail in being adjusted process, are convenient to rail and move reposefully.
Therefore, the beneficial effects of the utility model:
Owing to be provided with convex body in the above position of base, this convex body can directly be connected on the lateral surface of sleeper notch, thereby adjust in the operation process at gauge, by the sleeper notch and the mutual clamping of convex body produce one with the opposite power of the suffered reaction force of plunger, in addition under the qualification effect of rail to described prong, base is the very high stability of tool in operation process, and then assurance gauge adjustment operation can be finished smoothly.This hand-hydraulic space adjuster makes full use of the sleeper notch structure on the plain edition bolt fastener sleeper circuit, when operation, directly convex body is shelved in the sleeper notch, make the leading section of prong be plugged on the below of rail, do not need to utilize bolt and nut that base is fixed again separately, improved operating speed effectively.
