The principle of the invention is illustrated as follows:
the design can be applied to places such as ordinary speed railways, inter-city railways, high-speed railways, subways, trams and the like, and mainly measures the distance between the inner sides of the left and right steel rails.
Because the operation point can not guarantee whether a line is opened or not, the left and right steel rails of the opened railway can not be communicated with each other, once the left and right steel rails are communicated with each other, a train is displayed in a control center to be parked, the normal operation of the opened railway is influenced, the rail distance measurement is respectively supported on the left and right steel rails through racks, the insulation problem of the left and right steel rails is solved, meanwhile, the problems of component movement and durability are solved, the problem that the contact surface of the steel rails is finally determined to be insulated by selecting special electric insulation bearings is solved, the two positions can be insulated by 5000V voltage through tests, and the construction operation safety can be completely guaranteed.
The groove-shaped steel wheel on the right side of the frame is clamped on the steel rail, so that the reference edge is arranged on the inner side of the right steel rail. The distance between the left rail and the right rail is measured by measuring the distance between the inner sides of the left rail and the right rail, and the left rail and the right rail can be kept insulated by two electrically insulated bearings which are always supported on the inner sides of the rails to rotate, so that the distance can be measured, the electrically insulated bearings are respectively fixed at two ends of two racks, the gear is arranged in the center of the bottom plate, and the two racks are symmetrically distributed in mounting grooves at two sides of the gear. When the gauge changes in the dolly walking process, make the rack lengthen simultaneously or shorten simultaneously through the gear under the spring force effect of rack rear end, because the reference edge is on the right side steel rail, so the bottom plate can remove about simultaneously when rack length changes, the removal value is half behind the total extension or total shortening value subtraction standard gauge, because the actual gauge change volume is little, so this range finding telescopic stroke is set for to this range finding chi is 30 millimeters, effective range finding is between 1405 to 1465 promptly, when the detection car walks on the track optional position, can both be according to the instantaneous reading of scale position that indicates on the rack like this. When the gear rack is used on a wide rail or a narrow rail, the gear rack can be used only by correspondingly increasing or reducing the length of the gear rack.
Among four aluminum alloy support frames, two in the middle are used for bottom plate and frame bolted connection, and two on the edge are used for rack and frame bolted connection. Because the track gauge measuring ruler is continuously moved left and right in the work, in order to reduce the power loss of the spring, aluminum alloy materials are adopted as much as possible and hollowed out for lightening treatment, all sliding surfaces are used for reducing friction resistance and limiting, steel balls or rolling needles are adopted, and sliding friction is replaced by rolling friction.
