The guide shaft 33 of this embodiment has a hole at its end, and the other end of the elastic member 31 is fixed in the hole. The guide shaft 33 extends into the sleeve 34 from between the two frame bodies 14, and can move along the axial direction of the sleeve 34 and compress the elastic member 31; the end of the guide shaft 33 having the step 331 can be abutted by the end of the sleeve 34 to effect displacement of the guide shaft 33 in the axial direction (X direction).

The adjusting plate 35 is mounted on the bracket 12 by the adjusting screw 36, and the first surface 352 is spaced apart from the second surface 340. Specifically, the adjusting screw 36 passes through a pin hole 355 on the adjusting plate 35 and a pin hole 355 on the support plate 13, and the adjusting screw 36 is fixed on the bracket 12 by the adjusting nut 37. The adjusting nut 37 and the adjusting screw 36 have a predetermined amount of compression when they are screwed. In order to prevent the adjustment plate 35 from directly contacting the plate body 341 of the sleeve 34 or the support plate 13, an elastic pad 39 is provided on the second surface 340 (plate body). It is understood that the second surface 340 is provided with an elastic pad 39, and the elastic pad 39 surrounds the guide shaft 33. The connecting plate 22 is parallel to and opposite to the adjusting plate 35 and is fixedly connected with the movable part 20 and the mounting seat 10.

Referring to fig. 6, the distance between the first surface 352 of the adjusting plate 35 and the second surface 340 of the bracket 12 is an adjusting distance L3, and the maximum value of L3 is the maximum adjusting amount between the adjusting nut 37 and the adjusting screw 36, which is also the large expansion amount of the guide shaft. The distance between the sensing surface 201 of the metal sensing element 200 and the sensor (working surface) is the measuring distance L2. L1 is a safety distance, i.e., a distance between the sensing surface of the metal sensor 200 and the inner sidewall of the rail 1000, which is a constant value. It can also be understood as the safe distance between the metal sensing member 200 and the sensor during the running of the train.

In this embodiment, the adjusting nut 37 and the adjusting screw 36 have a predetermined compression amount when they are screwed, and the predetermined compression amount can compensate the transverse swing of the vehicle in the driving process, so that the distance L2 measured between the axle counting sensing plate and the axle counting sensor is not affected by the swing direction and the swing of the vehicle.

The distance of the adjusting plate 35 relative to the bracket 12 is moved by adjusting the position of the adjusting nut 37 on the adjusting screw 36, so that the adjustment of the adjusting distance of L3 is realized, and the value of the measuring distance L2 is ensured. L1 is a constant value, and in the case of ensuring that L1 is constant, it is possible to ensure that the measured distance L2 is constant or varies only slightly (tolerance range). Wherein, adjusting the adjustment distance L3 between the first surface 352 and the second surface 340 will change the elastic distance of the elastic member 31, that is, the length of the guiding shaft 33 in the sleeve 34 will change, for example, adjusting L3 to be larger, pulling the adjusting plate 35 away from the bracket 12 will drive the guiding shaft 33 to move away from the elastic member 31, and stretch the elastic member 31, and then be locked and fixed by the adjusting nut 37 and the adjusting screw 36.

It is understood that the maximum expansion adjustment distance L3 of the axle counting inductive converter 100 can determine the actual size of the guide axle 33 (i.e. the size required for the axial movement of the guide axle 33) according to the limit swing of the actual rubber wheel track 1000 vehicle. The transverse swing of the rubber wheel track 1000 vehicle has a swing to the left and a swing to the right, the axle counting induction converter 100 needs to be adjusted to an adjustment distance set by actual requirements through the adjustment screw 36 and the adjustment nut 37 in advance in actual installation application, and after the axle counting induction converter 100 and the guide frame 500 of the vehicle are installed, the adjustment nut 37 is positioned on the adjustment screw 36, so that the adjustment distance is greater than the limit swing of the vehicle.

It can be understood that, with the installation of metal response piece 200 on the installation roof beam 21 of adapter, if the vehicle is at the track 1000 in-process of traveling, the lateral oscillation who produces is too big, has influenced the safe distance L1 of metal response piece 200, can adjust the distance of regulation distance L3 through adjusting screw 36, and then guarantees safe distance, can guarantee to measure distance L2. In fact, the distance L2 between the metal sensing part 200 and the axle counting sensor 1010 is kept unchanged or slightly changed in the actual driving process, constant-distance sensing axle marking is achieved, the metal sensing part 200 is not affected by transverse swinging of the rubber-tyred rail train, the axle counting sensor 1010 can be guaranteed to be stable in axle counting, and the problem of axle loss and collision of the axle counting in application of the rubber-tyred rail train can be avoided.

Referring again to fig. 1, the axle counting induction converter 100 is provided on each guide frame 500 of the vehicle. The axle counting induction converter 100 of the present embodiment is connected to the guiding frame 500 of the vehicle through the mounting seat 10, specifically, connected to the mounting plate of the guiding frame 500. The rolling wheels 23 of the axle counting induction transducer 100 are in contact with the inner side wall 1001 of the rail 1000 and can rotate along the inner side wall 1001 of the rail 1000, actually rotating along with the running of the vehicle. It will be appreciated that the axle counting inductive transducer 100 is captured along its length between the inner side wall of the track 1000 and the mounting plate and moves as the vehicle moves. The metal sensing part 200 is formed by connecting two plate bodies 341, the surfaces (the surfaces with the largest area) of the two plate bodies 341 face different directions, and the surface of one plate body of the metal sensing part 200 is parallel to the mounting beam 21 and is connected with the adjusting hole 2111 through a screw; the sensing surface 201 of the other plate remote from the mounting beam 21 faces the inner side wall of the rail 1000, facilitating sensing by the axle counting sensor 1010. The response piece adopts two plate bodies 341 to connect, for the convenience of being connected with installation roof beam 21, simultaneously, because be two plate body connections, reduces the bulk rigidity, can cushion the impact force of vehicle driving in-process to metal tablet.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the invention.
