Description

Technical Field

[0001] The present invention relates to the technical field of rail vehicles, and more specifically, it relates to a detection device for obstacles on rail trains. Background Art

[0002] With the continuous expansion of the urban rail transit network scale and the wide application of fully automatic driverless train systems, the safe operation of trains has become the core issue of concern in the global rail transit industry. To ensure the operation safety of driverless trains, an obstacle detection device must be installed at the front end of the vehicle. After being triggered, it can make the vehicle apply emergency braking. The obstacle detection device is usually composed of a steel structure, which has an impact beam perpendicular to the driving direction. The impact beam is fixed to the main frame of the rail vehicle or fixed to the bogie frame by means of a mounting bracket.

[0003] The currently used obstacle detection device is a structure in which the detection cross beam is suspended and installed on the U-shaped leaf spring at the end of the frame. After the detection cross beam collides with an obstacle, the U-shaped leaf spring is deformed to trigger a travel switch, thereby generating train braking. Since the detection cross beam relies on a fixed stiffness structure, when encountering loose small obstacles, rigid collisions are likely to cause equipment damage, and too low stiffness will lead to a decrease in detection sensitivity. For this reason, we propose a detection device for obstacles on rail trains. Summary of the Invention

Detailed implementation mode

[0030] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be made in conjunction with the accompanying drawings of the specification.

[0031] In the following description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0032] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that may be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is separate or selectively mutually exclusive with other embodiments.

[0033] Embodiment 1 further describes a detection device for obstacles on a rail train proposed by the present invention, which includes two obstacle-removing crossbeams 100. The obstacle-removing crossbeams 100 are made of rectangular hollow beam profiles. Vertically hanging rods 101 are detachably installed on the two obstacle-removing crossbeams 100. It also includes a mounting plate 102. One end of the mounting plate 102 is detachably installed with an obstacle detection switch 103. The vertically hanging rod 101 correspondingly abuts against the obstacle detection switch 103. On one side of the mounting plate 102, reinforcing plates 104 are symmetrically and fixedly connected. On the corresponding surfaces of the two reinforcing plates 104, a combined plate 105 is integrally formed. On the upper end surface of the vertically hanging rod 101, a fixing ring 106 is integrally formed. A rotating shaft 107 is fixedly connected inside the fixing ring 106. Both ends of the rotating shaft 107 correspondingly penetrate through the reinforcing plates 104. An adjusting mechanism 200 is provided at the upper end of the combined plate 105;

[0034] Under normal conditions, when the train is running, the obstacle-removing crossbeam 100 at the front end of the train contacts an obstacle. Under the pressure of the obstacle, at this time, the vertically hanging rod 101 on the obstacle-removing crossbeam 100 contacts the obstacle detection switch 103. The normally closed contact in the external electrical connection box of the train opens and touches the normally open contact, causing it to close. When the normally open contact closes, it indicates that an obstacle has been detected. The detection information is transmitted to the subway central control system, thereby causing the train to perform an emergency brake. Figure 7It can be seen that when the vertical suspension rod 101 rotates to an angle &, the obstacle detection switch 103 will be triggered, thereby triggering the braking system of the train to achieve the detection function. The angle & is determined by the torsional stiffness of the rotating shaft 107 in the adjusting mechanism 200 and corresponds to the torsional stiffness threshold set for the obstacle. When the torsional stiffness received by the detection crossbeam is less than the threshold, the rotation angle of the vertical suspension rod 101 cannot reach the angle &, and the obstacle detection switch 103 will not be triggered. When the torsional stiffness received by the detection crossbeam is greater than or equal to the threshold, the rotation angle of the vertical suspension rod 101 reaches the angle &, and the obstacle detection switch 103 will be triggered;

[0035] In order to adjust the torsional stiffness of the inner rotating shaft 107 of the vertical suspension rod 101, the present invention further improves the existing obstacle removal crossbeam 100. By arranging an adjusting mechanism 200 inside the vertical suspension rod 101, by setting the resistance of the vertical suspension rod 101, when the obstacle removal crossbeam 100 encounters a smaller obstacle, the small obstacle is removed by the obstacle removal crossbeam 100 located at the front end of the obstacle detection device. At the same time, the torsional stiffness of the small obstacle is small, so it will not contact the vertical suspension rod 101 and the obstacle detection switch 103. In this way, the obstacle detection switch 103 will not be triggered, and the obstacle removal crossbeam 100 can directly sweep the small obstacle outside the track by means of the thrust when the train moves forward, thus reducing the sensitivity of the obstacle removal crossbeam 100 to obstacles;

[0036] If the mass of the detected obstacle is higher than the torsional stiffness of the set obstacle, the vertical suspension rod 101 fixed to the obstacle removal crossbeam 100 will rotate. At this time, the fixing ring 106 on the vertical suspension rod 101 rotates in the reinforcing plate 104 through the rotating shaft 107. At this time, the inner side of the vertical suspension rod 101 contacts the obstacle detection switch 103. The normally closed contact in the external electrical connection box of the train opens and touches the normally open contact to close it. When the normally open contact closes, it indicates that an obstacle has been detected, and the detection information is transmitted to the subway central control system, causing the train to perform an emergency brake;

[0037] The adjusting mechanism 200 includes a fixing member 201 arranged on the upper end surface of the bonding plate 105. One end of the rotating shaft 107 passes through the fixing member 201 and is provided with a movable member 202. An elastic member 203 is arranged in the fixing member 201. The movable member 202 and the elastic member 203 cooperate with each other. A rotating member 204 and a positioning member 205 are arranged in the fixing member 201. By Figures 1 to 6It can be seen that in the present invention, the rotating member 204 and the positioning member 205 cooperate with each other, so that the movable member 202 and the elastic member 203 cooperate with each other, thereby adjusting the resistance of the rotating shaft 107. In this way, the device can adjust the torsional stiffness of the vertical suspension rod 101 according to the actual situation. When the torsional stiffness is small, the obstacle removal cross beam 100 can directly sweep small obstacles outside the track by means of the thrust when the train runs forward. When the torsional stiffness is greater than the resistance of the rotating shaft 107, the inner side of the vertical suspension rod 101 contacts the obstacle detection switch 103, so that the train performs an emergency brake;

[0038] A positioning mechanism 300 is arranged between the two obstacle removal cross beams 100. The positioning mechanism 300 includes a docking member 301 arranged in the two obstacle removal cross beams 100. Locking members 302 are arranged in the obstacle removal cross beams 100. The docking member 301 and the locking members 302 cooperate with each other. A hollow hole 303 is arranged in the obstacle removal cross beam 100, and it is composed of Figures 6 to 10 It can be seen that the present invention simplifies the installation method of the obstacle removal cross beam 100. By setting a group of obstacle removal cross beams 100 in the prior art into two modular docking obstacle removal cross beams 100, the installation is relatively simple and convenient. In this way, the device can not only effectively realize the basic function of detecting obstacles, but also has a simple structure, reliable functions, and good practicability, reliability and maintainability.

[0039] Working principle: In summary, in the present invention, the rotating member 204 and the positioning member 205 cooperate with each other, so that the movable member 202 and the elastic member 203 cooperate with each other, thereby adjusting the torsional stiffness of the rotating shaft 107. In this way, the device can adjust the torsional stiffness of the vertical suspension rod 101 according to the actual situation. When the torsional stiffness is small, the obstacle removal cross beam 100 can directly sweep small obstacles outside the track by means of the thrust when the train runs forward. When the torsional stiffness is greater than the resistance of the rotating shaft 107, the inner side of the vertical suspension rod 101 contacts the obstacle detection switch 103, so that the train performs an emergency brake, and the installation method of the obstacle removal cross beam 100 is simplified. By setting a group of obstacle removal cross beams 100 in the prior art into two modular docking obstacle removal cross beams 100, the installation is relatively simple and convenient.

[0040] Embodiment 2

[0041] On the basis of Embodiment 1, the following technical features are added: The fixing member 201 includes a fixing block 201a integrally formed on the upper end surface of the bonding plate 105. A cavity 201b is provided in the fixing block 201a. A conical ring 201c is rotatably connected in the cavity 201b. A ring convex portion 201d is integrally formed on the inner wall of the conical ring 201c. A conical cavity 201e is provided in the conical ring 201c. The movable member 202 includes a movable plate 202a. One end of the rotating shaft 107 passes through the fixing block 201a and is fixedly connected to the movable plate 202a. The movable plate 202a is arranged in the conical cavity 201e. A notch 202b is provided in the movable plate 202a. A telescopic plate 202c is rotatably connected in the notch 202b. The elastic member 203 includes an arc-shaped groove 203a provided in the ring convex portion 201d. A compression spring 203b is fixedly connected in the arc-shaped groove 203a. One end of the compression spring 203b is fixedly connected to a slider 203c. The slider 203c is slidably connected in the arc-shaped groove 203a correspondingly. A first opening 203d is provided in the slider 203c. The telescopic plate 202c is correspondingly installed in the first opening 203d;

[0042] It can be Figures 5 to 6 seen that a circular fixing block 201a is fixedly connected to the upper end surface of the bonding plate 105. A cylindrical cavity 201b is provided in the fixing block 201a. A conical ring 201c is rotatably connected in the cavity 201b. A conical cavity 201e for accommodating the movable plate 202a is formed in the conical ring 201c. A ring convex portion 201d is integrally formed in the conical cavity 201e. An arc-shaped groove 203a is provided in the ring convex portion 201d. A slider 203c is connected in the arc-shaped groove 203a through a compression spring 203b. The movable plate 202a is arranged at the position of the conical cavity 201e where the rotating shaft 107 is located. One end of the telescopic plate 202c is rotatably connected in the notch 202b, and the other end is installed in the first opening 203d. In this way, by rotating the conical ring 201c forward or backward, the compression spring 203b is driven to rotate, thereby changing the resistance when the slider 203c moves;

[0043] Therefore, when the vertical suspension rod 101 rotates, the fixing ring 106 is driven to rotate. The fixing ring 106 drives the rotating shaft 107 to rotate in the reinforcing plate 104. While the rotating shaft 107 rotates, the movable plate 202a is driven to rotate in the conical cavity 201e. In this way, by changing the resistance when the slider 203c moves, the sensitivity of the vertical suspension rod 101 during rotation is reduced, so that the obstacle removal cross beam 100 can directly sweep small obstacles outside the track by means of the thrust when the train runs forward;

[0044] The rotating member 204 includes a second opening 204a provided in the conical ring 201c. The second opening 204a communicates with the conical cavity 201e correspondingly. A positioning block 204b is fixedly connected to the inner side of the second opening 204a. An auxiliary block 204c is movably connected in the second opening 204a. A curved groove 204d is provided on the outer wall of the auxiliary block 204c. The positioning block 204b is slidably connected in the curved groove 204d correspondingly. The positioning member 205 includes an auxiliary groove

[0045] 205a provided in the auxiliary block 204c. Two sides of the outer wall of the auxiliary block 204c are provided with first limiting grooves 205b. Two symmetrically arranged first limiting blocks 205c are fixedly connected to the top end of the inner wall of the cavity 201b. The first limiting blocks 205c are correspondingly arranged in the first limiting grooves 205b. A first threaded hole 205d is provided in the fixed block 201a. The first threaded hole 205d communicates with the cavity 201b correspondingly. A first screw rod 205e is threadedly connected in the threaded hole. The first screw rod 205e is rotatably connected in the auxiliary groove 205a correspondingly;

[0046] It can be seen from Figures 5 to 6 that a cylindrical second opening 204a is provided in the conical ring 201c. A square positioning block 204b is fixedly connected to the inner side of the second opening 204a. A cylindrical auxiliary block 204c is movably connected in the opening. An inclined curved groove 204d is provided in the auxiliary block 204c. The positioning block 204b is slidably connected in the curved groove 204d correspondingly. At the same time, the structure of the auxiliary block 204c is further defined in the present invention. Two vertical first limiting grooves 205b are provided on both sides of the auxiliary block 204c. A long first limiting block 205c is fixedly connected to the top end of the inner wall of the cavity 201b. The first limiting block 205c is slidably connected in the limiting groove correspondingly. A first screw rod 205e is rotatably connected in the auxiliary block 204c correspondingly. Therefore, when the first screw rod 205e rotates and moves downward, the auxiliary block 204c is driven to move vertically downward in the second opening 204a. When the resistance of the slider 203c during movement needs to be adjusted, only the first screw rod 205e needs to be rotated. Through the movement of the first screw rod 205e in the vertical direction, the auxiliary block 204c is driven to move in the vertical direction in the second opening 204a. Since the positioning block 204b is slidably connected in the inclined curved groove 204d correspondingly, the conical ring 201c is driven to rotate. Through the forward or reverse rotation of the conical ring 201c, the compression spring 203b is driven to rotate accordingly, so as to change the resistance of the slider 203c during movement. In this way, the sensitivity of the vertical suspension rod 101 during rotation is reduced, so that the obstacle removal cross beam 100 can directly sweep small obstacles outside the track by means of the thrust when the train runs forward;

[0047] Working principle: As can be seen from Embodiment 1, when it is necessary to adjust the critical value of the impact of the obstacle removal cross beam 100, by rotating the first screw 205e, through the movement of the first screw 205e in the vertical direction, the auxiliary block 204c is driven to move in the vertical direction in the second opening 204a. Since the positioning block 204b is slidably connected to the inclined curved groove 204d correspondingly, the conical ring 201c is driven to rotate. By the forward or reverse rotation of the conical ring 201c, the compression spring 203b is driven to rotate accordingly, thereby changing the resistance when the slider 203c moves. In this way, the sensitivity of the vertical suspension rod 101 during rotation is reduced or increased. When the sensitivity is reduced, when the obstacle removal cross beam 100 encounters a small obstacle, the small obstacle is swept by the obstacle removal cross beam 100 located at the front end of the obstacle detection device. At the same time, the torsional stiffness of the small obstacle is small, so the vertical suspension rod 101 will not contact the obstacle detection switch 103. If it is detected that the mass of the obstacle is higher than the torsional stiffness of the set obstacle, the vertical suspension rod 101 fixed to the obstacle removal cross beam 100 will rotate. At this time, the fixing ring 106 on the vertical suspension rod 101 rotates in the reinforcing plate 104 through the rotating shaft 107. At this time, the inner side of the vertical suspension rod 101 contacts the obstacle detection switch 103, and its detection information is transmitted to the subway central control system, so that the train performs an emergency brake.

[0048] Embodiment Three

[0049] On the basis of Embodiment 2, the following technical features are added: The obstacle detection switch 103 provided by the present invention is arranged at a relatively high position from the track, which improves the working environment of the obstacle detection switch 103, eliminates the need to design a protection box, reduces the weight of the device, and realizes the stability of the vertical suspension rod 101 during movement through the rotating shaft 107, improves the natural frequency of the entire component, reduces the sensitivity of the obstacle detection device to vibration, and improves the reliability of detection. Therefore, this device can not only effectively realize the basic function of detecting obstacles, but also has a simple structure, reliable functions, good applicability, reliability and maintainability;

[0050] It further includes an adjusting plate 114. The side circumference of the mounting plate 102 is provided with an activity hole 115. A third screw 116 is correspondingly arranged in the activity hole 115. The third screw 116 is correspondingly arranged on the adjusting plate 114. One side of the adjusting plate 114 is integrally formed with a reinforcing seat 117. A hanging ring 118 is arranged on the reinforcing seat 117. The reinforcing seat 117 is fixedly connected to the bogie at the front end of the train;

[0051] By Figures 1 to 4It can be seen that for the obstacle detection device provided by the present invention, the relative height between the adjusting plate 114 and the mounting plate 102 is adjustable. When the height of the detection crossbeam needs to be adjusted, it only needs to adjust the relative height between the adjusting plate 114 and the mounting plate 102 to achieve. Compared with the prior art, the maintenance is more convenient.

[0052] Working principle: In summary, by setting the obstacle detection switch 103 at a relatively high position from the track, the present invention improves the working environment of the obstacle detection switch 103, eliminates the need to design a protection box, reduces the weight of the device, and by adjusting the relative height between the adjusting plate 114 and the mounting plate 102, since the movable hole 115 is a long strip structure, it only needs to adjust the position of the screw three 116 between the adjusting plate 114 and the mounting plate 102, so that the relative height between the adjusting plate 114 and the mounting plate 102 can be achieved, thereby enabling the rapid adjustment of the position of the detection crossbeam in the vertical direction, and the maintenance is relatively convenient.
