Abstract
The invention discloses a metro vehicle barrier detector which comprises a group of air cylinders and air cylinder rods arranged in the air cylinders, wherein the transverse distance between each air cylinder rod and a barrier-to-be-detected detection device is kept within the range of 60-80 mm; the longitudinal height of each air cylinder rod is kept flush with the barrier-to-be-detected detection device; the three air cylinders are arranged on a detector frame at intervals and connected with an air source, a pressure adjustment valve and a control valve respectively; the pressure adjustment valve is used for adjusting the pressure of the air cylinders; the control valve is used for enabling the air cylinder rods to extend out from the air cylinders to impact a barrier detection device for detection. The metro vehicle barrier detector has the advantages of good universality, high convenience for operation, simple structure and 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 obstacle detection detector.
Background technology
The unpiloted subway that the whole world is used at present has two cities, and one is Singapore metro project, and one is Shanghai Underground No. 10 line.In order to guarantee the operation security of automatic driving vehicle, at the front end of vehicle, a barrier detecting apparatus all will be installed, make can allow vehicle apply the emergency brake after its triggering.But owing to there is no suitable checkout equipment, be difficult to the barrier detecting apparatus on vehicle to carry out functional verification and parameter adjustment.Product in the time of can only relying at present supplier and dispatch from the factory for barrier detecting apparatus is set, or the supporting testing tool of costliness that provides of procurement supplier, once in actual use sniffer break down or clash into foreign matter after be difficult to it to carry out function correction.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the existing deficiency of prior art, and a kind of have road ability, convenience, railcar obstacle detection detector simple in structure and with low cost are provided.
The present invention realizes the technical scheme that foregoing invention object takes: a kind of railcar obstacle detection detector, described detector comprises one group of cylinder and is located at the cylinder rod 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 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 used for adjusting cylinder pressure, described operation valve makes cylinder stretch out cylinder rod strikes obstacles sniffer to detect.
Further, described detector Rack Body below is provided with four groups of rollers.
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, the cylinder CQ2A50-200DC of two SMC brands, and the cylinder CQ2A80-200DC of a SMC brand, one group of pressure regulator valve, a 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 extent is 100-140mm, can adjust centre-height according to actual conditions.This detector need be fixed in tested barrier detecting apparatus front track while using, therefore designed four groups of rollers, facilitates instrument to slide at track, has designed hold down gag for instrument and rail are locked.4. each cylinder is with cylinder rod, while using detector, by pressure regulator valve, adjusts cylinder pressure, and operation control valve makes cylinder stretch out cylinder rod strikes obstacles sniffer, and different pressures value correspondence is actual, and to apply acting force as shown in the table.
Beneficial effect: this detector is simple in structure 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, the 2nd, and operation valve, the 3rd, roller, the 4th, hold down gag.
embodiment:
Below in conjunction with accompanying drawing, patent of the present invention is done to further operation instruction.
A kind of railcar obstacle detection detector, described detector comprises one group of cylinder and is located at the cylinder rod 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 are divided in detector frame and are connected with source of the gas and pressure regulator valve, operation valve respectively, described pressure regulator valve is used for adjusting cylinder pressure, and described operation valve makes cylinder stretch out cylinder rod strikes obstacles sniffer to detect.Wherein, described detector Rack Body below is provided with four groups of rollers; 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 both sides cylinder rod front end apart from 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 guaranteeing 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, adjust pressure regulator valve, tensimeter is tested after adjusting to corresponding numerical value.Three corresponding three of the left, center, right of operation valve cylinders, handle is that cylinder is opened position in left side, and middle is pressurize position, and right side is exhaust position.
4. corresponding handle is beaten in left side, cylinder rod stretches out strikes obstacles sniffer, after cylinder rod stroke is constant, handle is beaten in interposition.
5. the barrier detecting apparatus on pair vehicle carries out functional verification or adjustment, after off-test, recovers cylinder rod, turn-offs source of the gas, keeps airduct well, exits detection position.
The above is only the embodiment of patent of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of patent principle of the present invention; can also make some improvement, these improvement also should be considered as the protection domain of patent of the present invention.
