[0052] The roller 304 is connected to the bottom of the adjusting rod 303 .
[0053] In the present application, the length of the detection component can be adjusted by adjusting the first adjustment hole on the sleeve, the second adjustment hole on the adjustment rod, and the adjustment pin, so that the detection component can accurately detect the sleeper, and the detection result is more accurate and reliable. The roller rolling on the rail surface can reduce friction.
[0054] Figure 5 This is a schematic diagram of the mechanical sleeper detection device provided in this application in the retracted state. Figure 6 Another structural diagram of the mechanical sleeper detection device provided by the present application in the retracted state is shown in FIG. Figure 5 and Figure 6As shown, further, at least one second locking hole is provided on the connecting portion 301; at least one third locking hole is provided at the bottom of the first connecting rod 20; during detection, the second locking hole and the third locking hole are detachably locked by a second locking pin 305, so that the detection component 30 is locked together with the first connecting rod 20.
[0055] Furthermore, the first connecting rod 20 is arranged inside the detection box 10, and the bottom of the detection box 10 is provided with a first opening for the detection component 30 to pass through. When in use, the detection component rotates around the bottom end of the first connecting rod and rotates to the outside of the detection box to perform detection operations; after use, the detection component rotates around the bottom end of the first connecting rod and rotates to the inside of the detection box to limit the vehicle and retract.
[0056] Specifically, the detection device further includes a mounting base 80 , which is disposed inside the detection box 10 , and the top of the first connecting rod 20 is hinged to the mounting base 80 .
[0057] In the present application, the first connecting rod is installed by means of an installation base, which is more stable.
[0058] Specifically, the second openings are provided at both ends of the detection box 10, and longitudinal long through holes are provided on both sides of the detection box 10.

The second connecting rod rotates to drive the moving shaft and the moving sheet to move. The sensor obtains the detection signal of the sleeper by sensing the moving sheet. In the non-operation state, the detection component needs to be folded to prevent damage to the detection component. The second locking pin is disassembled to unlock the second locking hole and the third locking hole, so that the first connecting rod and the connecting part are hinged, so that the detection component can rotate relative to the first connecting rod. When the detection component rotates to the inside of the detection box, the corresponding two fourth locking holes are locked together by the third locking pin, so that the detection component is limited in the detection box, and the closure is realized, which is safer and more stable.
[0061] Figure 7 A schematic diagram of the structure of a working vehicle with a mechanical sleeper detection device provided in this application, such as Figure 7 As shown, the embodiment of the present application also provides a work vehicle with a mechanical sleeper detection device, including: a work vehicle body 1 and a mechanical sleeper detection device as described above, which is arranged at the bottom of the work vehicle body 1. Specifically, the detection box 10 is arranged at a position close to the sleeper at the bottom of the work vehicle body 1 by welding or bolting. Specifically, the work vehicle can be a rail vehicle such as a cleaning vehicle and a tamping vehicle. More specifically, the mechanical sleeper detection device can be directly arranged on the work vehicle body, or it can be arranged on an operating device on the work vehicle body. The operating device can be a track lifting device, a tamping device, and other devices for track operations.
[0062] The work vehicle provided in the present application includes the above-mentioned mechanical sleeper detection device, so it can be considered that the beneficial effects of the above-mentioned mechanical sleeper detection device are included, which will not be repeated here.
[0063] In the above embodiment 1, one spring is provided, and the spring 503 is provided between two mounting vertical plates 701; both ends of the spring 503 are connected to the mounting vertical plates 701 through two spring mounting blocks 504. In practical applications, two springs can also be provided, that is, springs are provided on both sides of the moving sheet, which can also meet the use requirements. The specific structure is described in the following embodiment 2.
[0064] Embodiment 2
[0065] The difference between Example 2 of the present application and Example 1 is that the moving component 50 includes two springs longitudinally sleeved on the outer wall of the moving shaft 501, and the two springs are respectively arranged between the moving plate and the two mounting vertical plates 701, one end of the spring is connected to the adjacent mounting vertical plates 701, and the other end of the spring is connected to the moving plate 502.
[0066] In the present application, two springs are provided, and the two springs perform opposite compression and extension operations during the detection operation. In the first embodiment, the moving sheet is used as the dividing point, and half of the spring and the other half of the spring perform opposite compression and extension operations. Both methods can meet the detection requirements.
[0067] Working principle:
[0068] Preparation stage: the working vehicle drives to the working position, and the mechanical sleeper detection device is lowered to the vicinity of the rail surface along with the working device; then the third locking pin is removed to rotate the connecting part of the detection component relative to the first connecting rod, thereby driving the bottom of the detection component to extend out of the detection box; the second locking hole and the third locking hole are locked together by the second locking pin, so that the first connecting rod and the connecting part are rigidly connected and will not rotate with each other; adjust the length of the detection component: adjust the length of the adjusting rod extending out of the adjusting sleeve, adjust it a little longer after the roller contacts the rail surface, and then lock the first adjusting through hole and the second adjusting through hole by the adjusting pin;
[0069] Operation phase: The mechanical sleeper detection device moves forward with the operation vehicle. Since the roller is in contact with the rail surface, the detection component is rigidly connected to the first connecting rod. Therefore, when there is a sleeper, the detection component can drive the first connecting rod to rotate, and then the second connecting rod to rotate, driving the moving shaft and the moving plate to move longitudinally, so that the sensor cannot sense the moving plate; when there is no sleeper, the detection component and the second connecting rod are in the initial position and will not rotate. Therefore, the second connecting rod, the moving shaft, and the moving plate are also in the initial position, and the sensor can sense the moving plate. Therefore, according to the rule that if the sensor senses the moving plate signal, there is no sleeper, and if the sensor does not sense the moving plate signal, there is a sleeper, the presence or absence of sleepers can be determined through the sensing signals of the sensor and the moving plate, and automatic detection of sleepers can be achieved.
[0070] At the end of the inspection and vehicle retraction stage: remove the second locking pin to unlock the second locking hole and the third locking hole, thereby hinged between the first connecting rod and the connecting part, so that the detection component can rotate relative to the first connecting rod, and when the detection component rotates to the inside of the detection box, the corresponding two fourth locking holes are locked together by the third locking pin, so that the detection component is limited in the detection box to achieve vehicle retraction.
