[0021] Example 2

[0022] Embodiment of the present invention: A schematic diagram of a bogie floating lever brake position size detection device and a detection method is shown in FIG. Figure 1 and Figure 2As shown, it includes a pull rod 1, a connecting rod 2, a guide rod 4 and a guide cylinder 7. One end of the guide rod 4 is inserted into the guide cylinder 7 and slidably cooperates with the guide cylinder 7. A scale line 6 is set on the guide rod 4. A positioning plug plate 5 is fixedly connected to the other end of the guide rod 4. A "U"-shaped fork 3 is hingedly connected to the middle of the guide rod 4. The pull rod 1 is welded to the end of the "U"-shaped fork 3. The connecting rod 2 is hingedly connected to the middle of the "U"-shaped fork 3. A right-hand hanging ear 12 is welded to the end of the outer wall of the guide cylinder 7, and the angle between the right-hand hanging ear 12 and the left-hand hanging ear 10 is 80°. The other end of the connecting rod 2 is hingedly connected to the right-hand hanging ear 12. Two connecting plates 8 are symmetrically welded at the other end of the guide cylinder 7. Two round pin holes 11 are opened on the two connecting plates 8, and a round pin 9 is inserted into one of the round pin holes 11. The lower part of the positioning plug plate 5 is an inverted trapezoidal structure, and two levels of shoulders 13 are symmetrically arranged on both sides of the positioning plug plate 5. The maximum size of each level of shoulder 13 corresponds to the process hole size of the center line of the bogie bolster. Therefore, it can be used to detect process holes of two sizes.

[0023] In this embodiment, the detection device is used to detect the right-hand braking position size of the bogie floating lever. The specific detection method is as follows: Since there is an 80° angle difference between the left-hand floating lever and the right-hand floating lever, when detecting the right-hand floating lever, the round pin 9 on the connecting plate 8 needs to be rotated 80° accordingly. At this time, the connecting rod 2 is disassembled from the left-hand hanging ear 10, and the connecting rod 2 is hinged to the right-hand hanging ear 12. Since the angle between the right-hand hanging ear 12 and the left-hand hanging ear 10 is 80°, the angle of the round pin 9 can be adjusted to facilitate the connection between the round pin 9 and the floating lever 14. During the detection, refer to Figure 4 First, connect the round pin 9 with the pin hole on the traveling lever 14, and then insert the positioning plug plate 5 on the end of the guide rod 4 into the process hole 15 on the center line of the bogie bolster. When the positioning plug plate 5 is inserted into the process hole 15, the largest part of the shoulder 13 on the positioning plug plate 5 is just stuck in the mouth of the process hole 15; at this time, pull the pull rod 1 by hand until the guide rod 4 and the guide cylinder 7 cannot move relative to each other, and then read the scale value of the corresponding scale line 6 on the guide rod 4. The scale value is the distance between the fulcrum on the traveling lever 14 and the center of the bolster, that is, the size of the braking position of the traveling lever.

[0024] In summary, the present invention can detect the size of the braking position of the floating lever in the two working conditions of the left and right hand of the bogie basic brake by adjusting the different connection modes of the left-hand hanging ear 10 or the right-hand hanging ear 12. At the same time, the present invention adopts the lever principle to make the floating lever 14 of the bogie basic brake reach the braking position, and at the same time, the guide cylinder 7 and the guide rod 4 with the scale line 6 are used to directly measure the value of the fulcrum braking position of the bogie floating lever 14, thereby reducing the labor intensity of the detector and improving the accuracy and detection efficiency of the braking position size detection. At the same time, the present invention sets the tensioning device and the detection device as one, and the detected size can be seen after the tension is in place, thereby improving the detection efficiency.
