Example

[0024] Please see Figure 1-4 The foreign object intrusion prevention device for the monorail vehicle bogie in this embodiment includes a bogie body 1. A running wheel 8 is mounted on the inner center of the bogie body 1. The running wheel 8 is driven by a drive device 6 to enable the monorail vehicle to move. Guide wheels 9 are mounted at the four corners of the bottom wall of the bogie body 1. Stabilizing wheels 10 are mounted on both sides of the bottom wall of the bogie body 1 between the two guide wheels to maintain the stability of the bogie body 1 during steering. Protective side plates 2 are symmetrically detachable and installable on both outer sides of the bogie body 1, allowing for quick removal of the protective side plates 2 for easy subsequent work. The staff inspected and maintained the bogie body 1; the protective side plate 2 is symmetrically hinged to the two sides with adjustment plates 3, and the inner side of the adjustment plate 3 is provided with an angle adjustment mechanism 4. The angle of the adjustment plate 3 can be adjusted by the angle adjustment mechanism 4, which can more promptly remove foreign objects; a first infrared sensor 21 is installed on the outer wall of the protective side plate 2, and a second infrared sensor 31 is installed on the outer wall of the adjustment plate 3. The first infrared sensor 21 and the second infrared sensor 31 can detect foreign objects around the bogie body 1 in a timely manner, thereby carrying out relevant measures to prevent foreign object intrusion.

[0025] For examples, please refer to Figure 1 and Figure 3A ventilation pipe 5 is fixedly installed on the outer wall of the protective side plate 2 below the first infrared sensor 21. Multiple jet nozzles 51 are evenly distributed on one side of the ventilation pipe 5. One end of the ventilation pipe 5 is connected to an air supply pipe 52, which is connected to the jet engine.

[0026] It should be noted that the control unit controls the jet engine to start, which delivers gas through the gas supply pipe 52 to the inside of the ventilation pipe 5, and blows air outward through several jet nozzles 51, which can disperse surrounding foreign objects.

[0027] For examples, please refer to Figure 1 An alarm 22 is installed on the side wall of the protective side plate 2. The alarm 22 is electrically connected to the first infrared sensor 21 and the second infrared sensor 31.

[0028] It should be noted that when the first infrared sensor 21 and the second infrared sensor 31 detect that a foreign object is approaching, they can promptly transmit a signal to the alarm 22 to provide a reminder.

[0029] For examples, please refer to Figure 1 and Figure 2 The angle adjustment mechanism 4 includes a fixed plate 41, which is symmetrically connected to the inner wall of the protective side plate 2. A cylinder 42 is installed on the inner wall of the fixed plate 41. A reinforcing connecting rod 43 is hinged to the top of the fixed plate 41. The end of the cylinder 42's actuator is hinged to the side wall of the reinforcing connecting rod 43. A support groove 44 is provided on the inner side of the adjustment plate 3. A slider is slidably connected to the inner side of the support groove 44. The bottom end of the reinforcing connecting rod 43 is connected to the slider.

[0030] It should be noted that the control cylinder 42 extends outward to drive the reinforcing link 43 to rotate. The slider at one end of the reinforcing link 43 slides inside the support groove 44, which can open the angle of the adjustment plate 3 outward. When the adjustment plate 3 is opened, it can effectively bounce away foreign objects that are in contact with its side wall, further improving the treatment effect of preventing foreign object intrusion.

[0031] For examples, please refer to Figure 4 The protective side plate 2 and the bogie body 1 are detachably installed through the installation mechanism 7. The installation mechanism 7 includes an abutment groove 71, which is opened at both ends inside the bogie body 1 and extends into the protective side plate 2. A stud 72 is threaded through the top of the protective side plate 2. An adjustment knob 73 is connected to the top of the stud 72, and an abutment seat 74 is connected to the bottom of the stud 72 by a bearing. The abutment seat 74 can be inserted into the abutment groove 71.

[0032] It should be noted that by adjusting the knob 73, the stud 72 is driven downward. The bearing connection between the stud 72 and the abutment seat 74 causes the abutment seat 74 to move downward along the inner wall of the abutment groove 71 until it is limited to the abutment groove 71 opened on the bogie body 1.

[0033] For examples, please refer to Figure 4 A through groove is provided on one side of the protective side plate 2 adjacent to the abutment groove 71. A sliding plate 75 is slidably connected in the through groove. A snap-fit ​​block 751 is fixedly connected to one side of the sliding plate 75. A snap-fit ​​groove 741 is provided on one side of the abutment seat 74. The snap-fit ​​block 751 and the snap-fit ​​groove 741 are snap-fitted together. A pull post 76 is fixedly connected to the other side of the sliding plate 75. An extension seat 77 is fixedly connected to the outer wall of the protective side plate 2. One end of the pull post 76 slides through the inner side of the extension seat 77, and a pull block 78 is connected to one end of the pull post 76. A spring 79 is fixedly wound around the outside of the pull block 78. One end of the spring 79 is connected to the side wall of the sliding plate 75, and the other end of the spring 79 is connected to the inner side wall of the extension seat 77.

[0034] It should be noted that pulling the pull block 78 outward causes the pull column 76 to move outward, and the pull column 76 causes the slide plate 75 to slide outward in the through groove, so that the locking block 751 is driven outward and away from the inside of the abutment groove 71. The movement of the pull column 76 compresses the spring 79. After the abutment seat 74 is completely in the abutment groove 71, the pull block 78 is released, so that the spring 79, under the elastic recovery, drives the pull column 76 to slide in the extension seat 77 towards the abutment groove 71, and drives the slide plate 75 to slide in the through groove towards the abutment groove 71. The locking block 751 is locked in the locking groove 741 under the recovery of the spring 79 and the pull column 76, thus realizing the installation between the protective side plate 2 and the bogie body 1. When disassembling, simply pull the pull column 76 outward to release the restriction on the abutment seat 74, and then move the abutment seat 74 upward away from the abutment groove 71 opened on the protective side plate 2, thus realizing the disassembly between the protective side plate 2 and the bogie body 1.

[0035] For examples, please refer to Figure 1 The first infrared sensor 21 and the second infrared sensor 31 are detachably mounted with a frame, which can be fixed to the protective side plate 2 and the adjustment plate 3 with bolts.

[0036] It should be noted that the first infrared sensor 21 and the second infrared sensor 31 can be protected by fixing the frame to prevent foreign objects from hitting them and causing damage.

[0037] In summary, the invention, through the protective side plate 2 and the adjusting plate 3, can prevent the intrusion of external foreign objects. Furthermore, in conjunction with the first infrared sensor 21, the second infrared sensor 31, and the alarm 22, it can promptly issue an alarm when a foreign object is detected approaching, thus alerting personnel. The surrounding foreign objects are cleared through the ventilation pipe 5, the air nozzle 51, and the air supply pipe 52. Under the action of the fixed plate 41, the cylinder 42, the reinforcing connecting rod 43, and the supporting slide 44, the angle of the adjusting plate 3 can be adjusted, allowing the adjusting plate to move when a foreign object is detected approaching. 3. It opens outward to eject foreign objects, providing a good effect in preventing foreign object intrusion. Secondly, through the abutment groove 71, stud 72, adjustment knob 73, abutment seat 74, snap-fit ​​groove 741, slide plate 75, snap-fit ​​block 751, pull column 76, extension seat 77, pull block 78 and spring 79, it can achieve stable installation between the protective side plate 2 and the bogie body 1. This makes it easy to disassemble the protective side plate 2 and adjustment plate 3 when inspecting and maintaining the bogie body 1, which is convenient for operation and has the advantages of preventing foreign objects, easy handling, and easy disassembly and assembly.

[0038] Working principle: Connect the protective side plate 2 to the bogie body 1. First, pull the pull block 78 outward to move the pull column 76 outward. The pull column 76 drives the slide plate 75 to slide outward in the through groove, so that the locking block 751 is driven outward and away from the inside of the abutment groove 71. The movement of the pull column 76 compresses the spring 79. After the locking block 751 leaves the inside of the abutment groove 71, the adjustment knob 73 is rotated to drive the stud 72 downward. The bearing connection between the stud 72 and the abutment seat 74 causes the abutment seat 74 to abut along the abutment. The inner wall of groove 71 moves downward until it is limited to the abutment groove 71 opened on the bogie body 1. After the abutment seat 74 is completely located in the abutment groove 71, the pull block 78 is released, so that the spring 79, under the elastic recovery, drives the pull column 76 to slide in the extension seat 77 towards the abutment groove 71, and drives the slide plate 75 to slide in the through groove towards the abutment groove 71. The locking block 751 is locked in the locking groove 741 under the recovery of the spring 79 and the pull column 76, thus realizing the connection between the protective side plate 2 and the bogie body 1. During installation and disassembly, simply pull the pull column 76 outward to release the restriction on the abutment seat 74, and then move the abutment seat 74 upward away from the abutment groove 71 opened on the protective side plate 2 to achieve disassembly between the protective side plate 2 and the bogie body 1. The protective side plate 2 and the adjusting plate 3 can prevent foreign objects from entering the interior of the bogie body 1. When the first infrared sensor 21 and the second infrared sensor 31 detect that a foreign object is approaching, they can promptly transmit the signal to the alarm 22 for reminder, and also transmit to the alarm 22 for reminder. The control unit controls the jet engine to start, delivering gas through the air supply pipe 52 to the inside of the ventilation pipe 5, and blowing air outward through several jet nozzles 51, which can disperse surrounding foreign objects. It also controls the start cylinder 42 to extend the actuator rod outward, driving the reinforcing link 43 to rotate. One end of the reinforcing link 43 slides inside the support groove 44, which can open the angle of the adjustment plate 3 outward. When the adjustment plate 3 is opened, it can effectively bounce away foreign objects that are in contact with its side wall, further improving the treatment effect of preventing foreign object intrusion.

[0039] The above-described embodiments are merely illustrative of certain implementations of the present invention, and are described in a relatively specific and detailed manner. However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
