Description
Technical field
The utility model relates to and is used for the special-purpose machinery that railway track has quarrel railway roadbed tamping operation, relates in particular to a kind of small forced vibrating asynchronous-clamping hydraulic tamper.
Background technology
Railway is because the effect that rolls of vehicle operating has the quarrel railway roadbed can produce the distortion sinking.For recovering the smooth-going of circuit, just need carry out the line tamping operation to guarantee the safety high speed operation of train.This is an important process of railway track road maintenance operation.
Traditional tamping operation is the full hand labour of manually using pick (cooperation rail jack).Work efficiency is low and labour intensity is big.The China railways sixties in last century embark mechanized maintenance, begin progressively to popularize to use light hydraulic tamping machine (being called for short little liquid smashes) to the seventies, are still the main type of general main line of china railway and branch line station track tamping operation so far.Begin from the eighties, China introduces external large-scale tamping machine.So far, with Austrian Prasy company is that the large-scale tamping car of representative is occupied an leading position in the whole world, China also introduces and production domesticization in Kunming Machinery Factory, and its adopts mechanical electronic hydraulic high-tech means, can synthesize based on what make firm by ramming and comprise several work requirements such as track lifting, track lining, arrangement.But the tamping car bodily form is huge like locomotive engine, reaches hundreds of kilowatt, up to a million dollars/of costs.Operation must be blocked circuit, takies " skylight " more than three hours.Be parked in the station nearby of construction point at ordinary times, can be voluntarily between station and job location.The requirement but biggest advantage fulfils assignment with being high-quality and high-efficiency now is mainly used in the maintenance tamping operation of special busy trunk lines." little liquid is smash " compared with large-scale tamping car, and it only has " making firm by ramming " function, and operating efficiency and tamping quality also far are inferior to large-scale tamping car.But because cost low (only surplus in the of ten thousand yuan/platform) (only hundreds of kilogram/platform) in light weight, the skylight time of dozens of minutes can the upper track operation, promptly descend the road after the end of job nearby, can open circuit rapidly and recover to transport.So do at general railway, still be extensive use of on the branch line.
Analyze the technical characterstic of existing tamping tool, what large-scale tamping car adopted is the operating principle of forced vibration and asynchronous-clamping reality." forced vibration " only the tamping pickaxe of 35HZ vibration frequency still has powerful perturbed force to ballast, the loosening ballast that is laminated to " hardening " after inserting railway roadbed." asynchronous-clamping is real " then can tackle the different resistances of ballast aggregate automatically.Be arranged under the sleeper ballast is closely knit again effectively.What little liquid was smash employing is eccentric block vibration (about 65HZ) and synchronous folder real (for reducing consolidated oil jar, adorning synchronizing bar between the tamping pickaxe) structure.Major advantage is that implement structure is simple, in light weight, and cost is low, the convenient use.The harden ability of railway roadbed of the contrast of two kinds of types, eccentric vibrational perturbation, the real effect of folder does not reach the operation effectiveness of asynchronous-clamping reality yet synchronously, because the resistance situation of ballast aggregate is inconsistent certainly everywhere.Have by railway maintenance rule (being called for short " dimension rule ") requirement, the tamping operation width of the every side of sleeper must not be less than 400 millimeters, otherwise can not guarantee the tamping operation quality again.
Summary of the invention
The purpose of this utility model is: guaranteeing to have under the prerequisite of good operation quality, providing that a kind of power is less, facility weight is light, failure rate of machinery is low, safe and reliable, simple in structure, volume is little, the small forced vibrating asynchronous-clamping hydraulic tamper that moves in light weight, convenient.
The purpose of this utility model realizes by following scheme: be made of lifting unit, traveling portion and exciting folder real part, improve at exciting folder real part, exciting folder real part is made of flywheel, splined shaft, capacity eccentric bearing, consolidated oil jar and pick plate.Belt one end is enclosed within the output shaft of motor, the other end is enclosed within on the splined shaft, and the splined shaft outboard end is with flywheel, and four capacity eccentric bearings are installed on the splined shaft successively, each capacity eccentric bearing outside connects an end of corresponding consolidated oil jar, and other end consolidated oil jar two ends connect the last fulcrum of corresponding pick plate.
The preferred excited frequency of the utility model exciting folder real part is 45-50HZ.
The utility model consolidated oil jar adopts the back pressure type consolidated oil jar.
The pick amplitude of pick plate described in the utility model is the 4-6 millimeter.
The utility model both can make the novel function of making firm by ramming utilize the valuable skylight activity duration more fully the tamping operation system miniaturization of forced vibration and asynchronous-clamping reality, can reduce the production and the use cost of machinery again greatly.And the tamping operation quality is better than the little liquid of existing eccentric vibration again and smashes, can adapt to more that China railways is generally done, the tamping operation of branch line, the utility model also has good security performance can guarantee safety of railway traffic, can guarantee operating personnel's personal safety again, and failure rate of machinery is low, reliability is preferably arranged, simple in structure, volume is little, in light weight, convenient moving.
