Abstract
The utility model provides a failure detector for tread surfaces of train wheels, which comprises fixing seats which are arranged on the outer side of a steel rail and a fixing plate. A swinging arm is arranged between the fixing plate and the fixing seat. A measuring ruler is arranged on the swinging arm through a screw bolt of the swinging arm. Both ends of a spring are respectively fixed to a supporting seat of the spring and the measuring ruler. At least one spacing mechanism is arranged between two fixing seats on both ends of the measuring ruler. Because the tread surfaces of the train wheels are use surfaces, the tread surfaces of the train wheels are used for measuring, which is accurate and reliable. The impact force of the train wheels to a mechanical measuring mechanism which moves horizontally is small.
Description
The utility model relates to a kind of train detection device, specifically relates to a kind of train wheel tread failure detector.
On the present railway to operating train wheel flat sliding, peel off, the detection of the damaged fault in the outside.The general four-bar linkage that adopts is fixed on the rail inboard, along pressing measuring scale, because vehicle wheel easily is attached with iron rust or other foreign matter above along being non-use face, easily produces false signal by vehicle wheel, causes measured error.
The purpose of this utility model just be to provide a kind of simple in structure, detect train wheel tread failure detector accurately.
The purpose of this utility model can realize by following measure:
The utility model comprises the permanent seat of settling the rail outside, adapter plate is bolted on the permanent seat by dowel bolt and swing arm, swing arm bottom fulcrum is arranged between adapter plate and the permanent seat and is placed in the inspection of swing arm spiral shell, measuring scale is placed in the swing arm by the swing arm bolt, the spring supporting seat is arranged on the permanent seat, on both ends of the spring difference fixing spring bearing and the measuring scale, between two permanent seats at measuring scale two ends, be mounted with at least one stop gear, stop gear comprises the spacing jig that is placed on the rail, on spacing jig, be mounted with the adjustment piece, adjusting screw rod is arranged on spacing jig and adjusts on the piece, positive stop strip is placed on the measuring scale, adjusting piece is the top that is placed in positive stop strip, and adapter plate is provided with to measure uses sensor, is mounted with on measuring scale and the corresponding locater plate of sensor.
The utility model is owing to adopt mechanisms such as the measuring scale be placed in the rail outside, permanent seat, sensor, and wheel tread is to use face, utilizes wheel tread to measure, accurately, reliable.Train wheel is little to the impulsive force of translation mechanical measurement mechanism simultaneously.
Accompanying drawing drawing of the present utility model is described as follows:
Fig. 1 is a scheme drawing of the present utility model.
Fig. 2 is that stop gear is installed in scheme drawing on the rail in the utility model.
The utility model is done to describe in detail below in conjunction with drawings and Examples:
As shown in the figure: the utility model comprises the permanent seat (3) of settling rail (28) outside, adapter plate (5) is fixed on the permanent seat (3) by dowel bolt (17) and swing arm bolt (18), swing arm (4) bottom fulcrum is arranged between adapter plate (5) and the permanent seat (3) and is placed on the swing arm bolt (18), measuring scale (1) is placed in the swing arm (4) by swing arm bolt (18), in the front portion of measuring scale (1) buffer gear (2) is arranged, be fixed on the measuring scale (1) by buffering binding bolt (19), spring supporting seat (7) is arranged on the permanent seat (3), on spring (8) two ends difference fixing spring bearing (7) and the measuring scale (1), between two permanent seats (3) at measuring scale two ends, be mounted with at least one stop gear (6), described stop gear comprises the spacing jig (26) that is placed on the rail (28), on spacing jig (26), be mounted with and adjust piece (27), adjusting screw rod (14) is arranged on spacing jig (26) and adjusts on the piece (27), positive stop strip (10) is placed on the measuring scale (1), adjusting piece (27) is the top that is placed in positive stop strip (10), adapter plate (5) is provided with sensor stand (24), measurement is installed on the sensor stand (24) with sensor (9), is mounted with on measuring scale (1) and the corresponding locater plate of sensor (9) (25).Specifically: permanent seat (3) is stuck on the rail (28) by binding bolt (21) with jig (29), by dowel bolt (17) and swing arm bolt (18) adapter plate (5) is fixed on the permanent seat (3), swing arm (4) bottom fulcrum is installed between adapter plate (5) and the permanent seat (3), and is fixing by swing arm bolt (18); The upper end is installed on the measuring scale on (1) by swing arm bolt (18).Spring supporting seat (7) is fixed on the permanent seat (3) by bolt (23); Spring (8) lower end is installed on spring bearing (7) and the lower spring bearing (15), and the upper end is connected with measuring scale (1) with upper spring seat axle (20) by upper spring seat (16), and measuring scale is supported.The spacing jig (26) of stop gear (6) is fixed on the rail (28) by binding bolt (21), adjusts piece (27) and is connected on the spacing jig (26) by bolt (12); Adjusting screw rod (14) and adjustment nut (11) is connected spacing jig (26) and adjusts on the piece (27) by set pin (22).Positive stop strip (10) is installed on the side plate of measuring scale (1), and the adjustment piece (27) of stop gear (6) is suspended on the top of positive stop strip (10).
Principle of work of the present utility model is as follows: be mounted with six groups of devices of the present utility model of symmetry in twos respectively in the rail both sides, press the measuring scale of this utility model device when wheel tread after, the impulsive force that the buffer gear absorption portion wheel of measuring scale front end produces; Simultaneously, the downward translation of measuring scale, the locater plate synchronous shift on the measuring scale, the displacement pickup that install the locater plate below detects the displacement of locater plate.When faults such as scratch were arranged when wheel tread, when having abrasive position to be rolled on the measuring scale, wheel center can move down, and the distance that moves down is exactly to abrade the degree of depth, is detected by displacement pickup.After wheel passed through measuring scale, under the application force that spring makes progress, measuring scale moved up, and is restricted to initial condition by stop gear.
