DETAILED DESCRIPTION

[0022] The utility model embodiment provides an infrared early warning track buffer, such as Figure 1-4As shown, it includes a mounting base 101, and threaded holes are provided at the four corners of the mounting base 101 for easy installation. A buffer base 102 is fixedly provided on one end surface of the mounting base 101, and a buffer cylinder 103 is fixedly provided on one end surface of the buffer base 102. A telescopic cavity 110 opening outward is provided in the buffer cylinder 103, and a telescopic buffer rod 107 capable of telescopic movement is provided in the telescopic cavity 110, and a buffer unit 106 is provided on the top of the telescopic buffer rod 107.

[0023] Furthermore, a buffer tube 103 is disposed inside the telescopic buffer rod 107 , and an outer end surface thereof is sleeved with a rotatable adjustment ring 108 , which is in a circular shape.

[0024] Furthermore, detection bases 104 are fixedly provided on both sides of the outer end surface of the adjustment ring 108, and the detection bases 104 on both sides are symmetrically positioned.

[0025] Furthermore, an infrared detector 105 is installed on one end surface of the detection base 104 , and the detection direction of the infrared detector 105 is toward the buffer unit 106 .

[0026] It should be further explained that the infrared detector 105 is an infrared detector, and the infrared detection direction of the infrared detector 105 is toward the end surface of one side of the buffer unit 106 .

[0027] Furthermore, a buffer cavity 111 opening outward is provided in the telescopic buffer rod 107 , and an energy absorbing unit 112 is fixedly provided at the top end of the buffer cavity 111 .

[0028] Furthermore, a movable supporting plate 114 is provided in the telescopic cavity 110 , and a connecting rod 113 is installed between the supporting plate 114 and the energy absorbing unit 112 to achieve a fixing effect.

[0029] Furthermore, signal receivers 109 are fixedly provided on both sides of the end surface of one side of the installation base plate 101 , and the signal receiver 109 is connected to the infrared detector 105 by signal.

[0030] It is worth further explaining that the signal receiver 109 is a signal alarm, and the buffer unit 106 and the unit in the buffer cavity 111 can be a high-performance spring group, or a hydraulic system or a composite material energy absorption technology.

[0031] When using this solution, taking the hydraulic system as an example, first drive the mounting base plate 101 to move as a whole to the track mounting position, and fix it through the threaded holes on the four sides of the mounting base plate 101, and stably install the buffer unit 106 to align with the working direction where vehicle buffering is required in the track.

[0032] When the rail vehicle is buffering, the buffer unit 106 first contacts one end of the rail vehicle. When one end of the buffer unit 106 is subjected to impact force, the buffer unit 106 pushes the telescopic buffer rod 107 to move into the telescopic cavity 110, and pushes the connecting rod 113 to drive the supporting movable plate 114 to move into the telescopic cavity 110. The hydraulic system inside the telescopic cavity 110 has a buffering and energy-absorbing effect, thereby being able to play a protective role in inevitable contact or collision and minimize damage to equipment and cargo.

[0033] At the same time, during the buffering process, the infrared detector 105 performs infrared distance detection on the back of the buffer unit 106. When the infrared detector 105 detects that the distance of the buffer unit 106 is rapidly approaching, the signal is transmitted and controlled to output the signal through the signal receiver 109, and an alarm is issued after receiving the signal through the main control end. At the same time, the infrared detection distance is recorded through signal transmission, and a data model is established to facilitate subsequent comparison and early warning work.

[0034] During normal operation, the infrared detector 105 monitors the distance and motion state of objects around the device. Once a potential collision risk is detected, a signal is immediately sent to the control unit through the signal receiver 109. The control unit analyzes the received data and compares it with the data model established by the previous collision. If it is determined that the collision risk is high, the alarm module is triggered to issue an emergency warning through sound and light signals or directly communicate with the central console to prompt the operator to take emergency avoidance measures.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
