Description
(1) technical field
The utility model relates to the online inspection vehicle of a kind of rail yard decelerating, particularly carries field, the biomimetic type station decelerating presence inspection vehicle of hydraulic power unit, employing accumulator.
(2) background technology
In China, decelerating has become the indispensable advanced speed governing equipment of rail yard, has installed approximately more than 100 ten thousand in field, more than 200 stations and factories and miness at present. but safeguard aspect equipment at a station decelerating, be applicable to " decelerating presence checkout gear " that rail yard uses and also rarely have report. for many years, just rely on rail yard staff to step on mode with artificial pin and station track decelerating is carried out at a slow speed and step on down fast, estimate oil gas counter-force and the braking counter-force of sentencing decelerating with personal experience, and judge that can it continue online use. this detection mode efficiency is low, shortage standard and data, labour intensity are large, and jeopardizes personal safety, can not meet the demand for development of rail yard decelerating governing system scientific maintenance. the decelerating state online detection instrument of standing, due to needs simulate Railway wheelset by time decelerating applied to instantaneous pressure survey its counter-force, in view of on-the-spot condition, the inspection vehicle of existing research and development and single performance checkout gear not yet reach gratifying practical function. for example, utility model patent " a kind of railway decelerating performance Site Detection car " (CN203651771U), a kind of decelerating Site Detection car that relies on two cover bicycle and mans to drive is disclosed, detection wheel and the force cell of simulating wheel are housed on inspection vehicle, control display etc., when work, this bicycle drives inspection vehicle to move on rail, in the time detecting the cap head of taking turns the sliding oil cylinder that is pressed onto decelerating, can produce a counter-force to detecting wheel, by force cell and control display, this counter-force is processed and shown, finding out counter-force under off working state is greater than permission maximum or is less than the fault decelerating that allows minimum of a value. because decelerating is less in the counter-force under off working state, generally in 80～90kg left and right, and more than counter-force under duty can reach 1.6t, for avoiding tested decelerating to enter duty, specify that the speed of travel of this inspection vehicle in testing process should be lower than the critical speed 4.5km/h of decelerating. therefore this inspection vehicle only detects the oil gas counter-force of decelerating under off working state, does not test for the braking counter-force of decelerating. so the existing rail yard decelerating inspection vehicle only alternative staff of patrolling and examining with the Inspection of stepping under pin " at a slow speed ", and is sentenced the operation whether tested decelerating do work and still can not be realized with stepping under pin " fast ", estimating.
(3) utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of field, biomimetic type station decelerating presence inspection vehicle that carries hydraulic power unit, adopts accumulator, the fault deceleratings such as dead top that online decelerating is existed, leakage of oil, gas leakage carry out qualitative anticipation, step on to estimate to substitute the artificial pin of current employing the backward operating type of sentencing decelerating quality, realize online decelerating is carried out to science, effective qualitative detection.
The technical solution of the utility model is achieved in that a kind of online inspection vehicle of field, station decelerating that can move on railway track, is made up of vehicle frame, batteries, hydraulic power unit, hydraulic control device, testing arrangement, electric control box, operation control box and relevant data acquisition analytical system that rail insulation travelling wheel is housed. Accumulator, check valve, magnetic valve, overflow valve, choke valve, Pressure gauge, relief valve and fuel tank are housed in hydraulic control device; Dynamometry oil cylinder, clamping cylinder, claw, force cell are housed in testing arrangement; Power switch, computer display screen, single board computer, hydraulic pressure indicator are housed in operation control box. In the time that this inspection vehicle is worked on field wire road, station, first turn on the power switch, make motor rotarily drive hydraulic pump output hydraulic pressure oil. Then through oil path control system, accumulator energy storage to pressure, the motor set stopped to pump oil. In the time that need detect, utilize accumulator oil pressure, through circuit, oil path control system control, make dynamometry cylinder piston rod stretch to tested decelerating mushroom head: to stretch out at a slow speed for the first time the mushroom head that presses to decelerating, imitate manually at a slow speed pin step on action, test decelerating oil gas counter-force; Stretch out fast for the second time the mushroom head that presses to decelerating, imitate artificial pin fast and step on action, the braking counter-force of test decelerating. Because the energy storage effect of accumulator and the configuration of pipeline make the piston rod fast-descending of dynamometry oil cylinder, speed has exceeded the critical speed of decelerating acting, and therefore can this checkout equipment can be tested decelerating and do braking work. After twice test of mechanism, find out fault top according to the oil gas counter-force of setting and the upper limit value and lower limit value of braking counter-force after testing, finally complete the presence of online decelerating is detected to data processing by data acquisition and analysis system. In the time that accumulator oil pressure drops to the pressure of setting, hydraulic pump standing-meeting is automatically to accumulator repairing, and repairing completes rear motor and automatically stops. This inspection vehicle can substitute former artificial pin and step on the backward operating type that detects decelerating duty, improve testing efficiency, realize the effectively management one by one to a station online decelerating, guarantee station decelerating governing system reliably, normally operation, for ensureing that a station Safety of Shunting Operation provides effective means.
