Description

A kind of light rail flaw detection trolley
Technical field
The present invention relates to railway track defect-detecting equipment, especially railway track automatic flaw detection dolly.
Background technology
Railway track defect directly influences train operating safety, and train in the process of running, friction is produced to rail, is squeezed Pressure, rail is produced micro-deformation, when rail dispatches from the factory in addition inside have some micro defects, rail in train for a long time repeatedly The defects of under effect, easily cracking, be scaling-off, being broken, rail internal flaw also can gradually increase, and be acted in fatigue stress Under, easily it is broken, has a strong impact on traffic safety.
Present rail examination work is one important process of railway working system, and the ultrasonic examination used at present has:Hand Carry out supersonic detector, upper and lower road is convenient, and inspection speed 2Km/h, speed is slow, and efficiency is low;The electronic flaw detection trolley of rail row, Although flaw detection efficiency reaches more than 20Km/h, left and right can only respectively place one group of flaw detection wheel, it is impossible to according to different sections of highway and rail by The increase of power situation reduces defect-detecting equipment, and flaw detection wheel angle can not be adjusted, and flaw detection effect is not very good, if more dolly work Cost of equipment and manpower expense are added again, while dolly weight is also inconvenient in more than 100Kg, upper and lower road;It is also a kind of big Type supersonic detecting vehicle, multigroup flaw detection wheel, the speed of service is high, but some defects can not substantially be found, it is also necessary to artificial effect, should Equipment price is very expensive, and road bureau's configuration is seldom, although detection efficient is high, stills need artificial effect and confirms, influence service efficiency, It is strict to run formality, it is impossible to meet needs.
The content of the invention
It is an object of the invention to provide a kind of in light weight, upper and lower road is convenient, and defect-detecting equipment can be according to the busy section of railway Need increase or decrease at any time, flaw detection wheel angle adjustable, while detect a flaw wheel will not be due to bend relative to the position of rail Rail difference in height and change, flaw detection precision is high, and the speed of service reaches 30Km/h flaw detection trolley.
The technical scheme is that:The light rail flaw detection trolley of the present invention, including driving dolly and flaw detection trolley group Into.Driving dolly is made up of the part such as driving moment, car body, seat, pedal, electrical system, workbench.Electric machine is in aluminium In alloy wheel, driving moment is advanced, and car body is semi arch structure, is welded and connected by light-duty alloy material group, and 4 are provided with car body Seat, being used for maintenance and human pilot, car body is provided with rapid insertion device, is connected with inspection car Quick Connect Kit, Car body can be folded.It is characterized in that car body is welded after being bent by light high-intensity alloy, in light weight, car body both ends installation Wheel position can be folded into car body, reduce overall dimension, convenient transportation.
Flaw detection trolley is made up of wheel, flaw detection kickstand, flaw detection mechanism, elastic telescopic support, material platform etc..Detect a flaw small Car is articulated on driving dolly by attachment means, is collectively constituted and is integrated with driving dolly, and flaw detection kickstand passes through two bullets Property telescope support connection, connected by the compression of spring, remain that flaw detection kickstand both sides position is protected with rail inner side Hold it is constant, so, no matter rail is straight line or bend(Bend rail height is different), the same steel in flaw detection trolley position can be ensured Rail inner side is relatively constant, and flaw detection mechanism is arranged on flaw detection kickstand, and micromatic setting is taken turns provided with flaw detection, and flaw detection wheel can be hung down Directly distance is adjusted in rail direction and rotated along Rail Surface, so flaw detection wheel is adjusted as needed, ensure to visit It is accurate to hinder effect.It can mount multiple flaw detection trolleys according to different sections of highway needs at first flaw detection trolley rear portion, complete side can be carried out Position flaw detection, ensure that defect is found in time.It is characterized in that flaw detection wheel can carry out straight line and angular adjustment, flaw detection wheel position is the same as in rail Side position is relatively fixed, and the wheel position that will not be detected a flaw because of rail height change changes, and influences quality of detecting a flaw.Meanwhile according to need More inspection cars can be fixed to detect a flaw to rail.
Advantages of the present invention:1st, dolly and flaw detection trolley independent design are driven, dismounting is quick, in light weight, convenient in carrying.2、 Car body circular shape is driven, load capacity is big, folds rear drive sprocket in car body, reduces space.3rd, flaw detection trolley support has two Root elastic telescopic support connects, and ensures that flaw detection wheel is constant with the position on the inside of rail.4th, flaw detection wheel can enter along rail vertical direction Row is mobile to be adjusted and is rotated along Rail Surface, meets rail examination demand.5th, drive after dolly and continuously mount more spies Hinder dolly, while wheel of detecting a flaw can adjust various different angles, ensure that rail all surface carries out reliable detection.
The embodiment that the invention will now be described in detail with reference to the accompanying drawings.
