Abstract
The invention discloses a kind of railcar detection of obstacles instrument, the cylinder rod that described detector comprises one group of cylinder and is located in cylinder, lateral separation between described cylinder rod and barrier detecting apparatus to be measured remains between 60mm ~ 80mm, longitudinally keep highly with it flushing, described cylinder is three, described three cylinder intervals to be divided in detector frame and to be connected with source of the gas and pressure regulator valve, operation valve respectively, described pressure regulator valve is for adjusting cylinder pressure, and described operation valve makes cylinder stretch out cylinder rod strikes obstacles sniffer to detect.The invention has the advantages that versatility is good, convenient operation, structure are simple and with low cost.
Description
Technical field
The present invention relates to a kind of detector.More specifically, the present invention relates to a kind of railcar detection of obstacles instrument.
Background technology
The unpiloted subway that the current whole world uses has two cities, and one is Singapore metro project, and one is Shanghai Underground No. 10 line.In order to ensure the operation security of automatic driving vehicle, in the front end of vehicle all by installation barrier detecting apparatus, vehicle after making it trigger, can be allowed to apply the emergency brake.But owing to there is no suitable checkout equipment, be difficult to carry out functional verification and parameter adjustment to the barrier detecting apparatus on vehicle.Product setting when supplier dispatches from the factory can only be relied at present, or the supporting testing tool of costliness that procurement supplier provides, in actual use once sniffer breaks down or be difficult to carry out function correction to it after clashing into foreign matter for barrier detecting apparatus.
Summary of the invention
The technical problem to be solved in the present invention is the deficiency overcome existing for prior art, provides a kind of and has road ability, convenience, structure railcar detection of obstacles instrument simple and with low cost.
The present invention realizes the technical scheme that foregoing invention object takes: a kind of railcar detection of obstacles instrument, the cylinder rod that described detector comprises one group of cylinder and is located in cylinder, lateral separation between described cylinder rod and barrier detecting apparatus to be measured remains between 60mm ~ 80mm, longitudinally keep highly with it flushing, described cylinder is three, described three cylinder intervals to be divided in detector frame and respectively with source of the gas and pressure regulator valve, operation valve is connected, described pressure regulator valve is for adjusting cylinder pressure, described operation valve makes cylinder stretch out cylinder rod strikes obstacles sniffer to detect.
Further, four groups of rollers are provided with below described detector Rack Body.
Further, the cylinder bore in the middle of in described three cylinders is more bigger than the cylinder bore of the left and right sides.
In the present invention, detector is by erecting frame, and the cylinder CQ2A50-200DC of two SMC brands, the cylinder CQ2A80-200DC of a SMC brand, one group of pressure regulator valve, tensimeter, three operation valves, four groups of rollers and hold down gag form.Wherein two cylinder CQ2A50-200DC are in the left and right sides, centre distance 2040mm, and cylinder CQ2A80-200DC is in centre.Consider that every train barrier detecting apparatus height is different, the part of detecting of detector is adjustable up and down, and detector mounting center height adjustable scope is 100-140mm, can adjust centre-height according to actual conditions.This detector need be fixed in tested barrier detecting apparatus front track when using, therefore devises four groups of rollers and facilitate instrument at tracks travel, devises hold down gag for instrument and rail being locked.4. each cylinder is with cylinder rod, and when using detector, adjust cylinder pressure by pressure regulator valve, operation control valve makes cylinder stretch out cylinder rod strikes obstacles sniffer, and the corresponding actual applying acting force of different pressures value is as shown in the table.
Beneficial effect: this detector structure is simple and with low cost, can carry out functional verification and parameter adjustment to subway vehicle barrier sniffer easily.
Accompanying drawing explanation
Fig. 1 is the front view of the embodiment of the present invention;
Fig. 2 is the vertical view of the embodiment of the present invention; Wherein 1 is cylinder, and 2 is operation valves, and 3 is rollers, and 4 is hold down gags.
embodiment:
Below in conjunction with accompanying drawing, further operation instruction is done to patent of the present invention.
A kind of railcar detection of obstacles instrument, the cylinder rod that described detector comprises one group of cylinder and is located in cylinder, lateral separation between described cylinder rod and barrier detecting apparatus to be measured remains between 60mm ~ 80mm, longitudinally keep highly with it flushing, described cylinder is three, described three cylinder intervals to be divided in detector frame and to be connected with source of the gas and pressure regulator valve, operation valve respectively, described pressure regulator valve is for adjusting cylinder pressure, and described operation valve makes cylinder stretch out cylinder rod strikes obstacles sniffer to detect.Wherein, four groups of rollers are provided with below described detector Rack Body; Cylinder bore in the middle of in described three cylinders is more bigger than the cylinder bore of the left and right sides.
Detection method is as follows: 1. detector is placed in before tested barrier detecting apparatus, make cylinder rod front end, both sides distance barrier detecting apparatus 60mm ~ 80mm, detector centre-height and tested device basic horizontal, lock detector and rail with hold down gag simultaneously.
2. the airduct of detector and source of the gas are connected, for ensureing air quality, source of the gas is generally taken from vehicle air reservoir, guarantees source of the gas air pressure 0.5MPa≤P < 1MPa.
3., when barrier detecting apparatus is surveyed in test, according to table 1 data point reuse pressure regulator valve, tensimeter is tested after adjusting to corresponding numerical value.Three operation valve corresponding three, left, center, right cylinders, handle is that cylinder opens position in left side, and middle is pressurize position, and right side is exhaust position.
4. beat in left side by corresponding handle, cylinder rod stretches out strikes obstacles sniffer, beats handle in interposition after cylinder rod stroke is constant.
5. the barrier detecting apparatus on pair vehicle carries out functional verification or adjustment, after off-test, recovers cylinder rod, turns off source of the gas, keep airduct well, exit and detect position.
