A detection device for obstacles on rail trains

Abstract

This invention discloses a detection device for obstacles on rail trains, relating to the field of rail vehicle technology. It includes two obstacle-clearing beams with vertical hangers on each beam, and a mounting plate. One end of the mounting plate has an obstacle detection switch. Reinforcing plates are symmetrically arranged on one side of the mounting plate, and connecting plates are arranged on opposite sides of the reinforcing plates. A fixing ring is provided on the upper surface of the vertical hanger, and a rotating shaft is located within the fixing ring. An adjustment mechanism is provided on the upper surface of the connecting plate. This invention adjusts the torsional stiffness of the vertical hanger through the adjustment mechanism. When the torsional stiffness is low, the obstacle-clearing beam can directly sweep small obstacles off the track using the thrust of the train moving forward. When the torsional stiffness is greater than the resistance of the rotating shaft, the inner side of the vertical hanger contacts the obstacle detection switch, thereby causing the train to brake suddenly. Furthermore, the positioning mechanism makes the obstacle-clearing beam easy and convenient to install.

Description

Technical Field

[0001] This invention relates to the field of rail vehicle technology, and more specifically, to a detection device for obstacles on rail trains. Background Technology

[0002] With the continuous expansion of urban rail transit networks and the widespread application of fully automated driverless train systems, train operation safety has become a core issue of concern in the global rail transit industry. In order to ensure the operational safety of driverless trains, an obstacle detection device must be installed at the front of the vehicle. When triggered, the device can apply emergency braking. The obstacle detection device is usually composed of a steel structure with an impact beam perpendicular to the direction of travel. The impact beam is fixed to the main frame of the rail vehicle or fixed to the bogie frame by means of mounting brackets.

[0003] The obstacle detection device currently in use consists of a detection beam suspended on a U-shaped leaf spring at the end of the frame. When the obstacle detection beam collides with an obstacle, the U-shaped leaf spring deforms, triggering a limit switch and thus braking the train. Since the detection beam relies on a fixed rigidity structure, rigid collisions with loose small obstacles can easily damage the equipment. Insufficient rigidity can also lead to a decrease in detection sensitivity. Therefore, we propose a detection device for obstacles on rail trains. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this invention, the resistance of the slider during movement is changed by adjusting the mechanism, thereby reducing the sensitivity of the vertical rod when it rotates. When the obstacle removal beam encounters a small obstacle, it removes the small obstacle through the obstacle removal beam located at the front end of the obstacle detection device. If the mass of the obstacle is detected to be higher than the set torsional stiffness of the obstacle, the vertical rod fixed to the obstacle removal beam will rotate.

[0018] 3. In this invention, by setting the obstacle detection switch at a higher position above the track, the working environment of the obstacle detection switch is improved, eliminating the need for a protective box and reducing the weight of the device. Furthermore, by adjusting the relative height between the adjustment plate and the mounting plate, the vertical position of the detection beam can be quickly adjusted, making maintenance more convenient.

Detailed Implementation

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

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

[0032] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0033] Example 1 further describes the obstacle detection device for rail trains proposed in this invention, which includes two obstacle removal beams 100. The obstacle removal beams 100 are rectangular hollow beam profiles. Vertical rods 101 are detachably installed on the two obstacle removal beams 100. It also includes a mounting plate 102. An obstacle detection switch 103 is detachably installed on one end of the mounting plate 102. The vertical rods 101 are correspondingly abutted against the obstacle detection switch 103. A reinforcing plate 104 is symmetrically fixedly connected to one side of the mounting plate 102. A connecting plate 105 is integrally formed on the corresponding side of the two reinforcing plates 104. A fixing ring 106 is integrally formed on the upper end surface of the vertical rods 101. A rotating shaft 107 is fixedly connected inside the fixing ring 106. The two ends of the rotating shaft 107 pass through the reinforcing plate 104 respectively. An adjustment mechanism 200 is provided on the upper end of the connecting plate 105.

[0034] Under normal conditions, when the train is running, its front obstacle-clearing beam 100 comes into contact with an obstacle. Under the pressure of the obstacle, the vertical rod 101 on the obstacle-clearing beam 100 contacts the obstacle detection switch 103. This opens the normally closed contact in the train's external electrical connection box, triggering the normally open contact to close. When the normally open contact closes, it indicates that an obstacle has been detected. This detection information is transmitted to the subway central control system, causing the train to perform emergency braking. Figure 7It is known that when the vertical boom 101 rotates to angle &, it will trigger the obstacle detection switch 103, thereby triggering the train's braking system to perform the detection function. The angle & is determined by the torsional stiffness of the rotating shaft 107 in the adjustment mechanism 200, which corresponds to the torsional stiffness threshold set for the obstacle. When the torsional stiffness of the detection beam is less than the threshold, the vertical boom 101 will not rotate to angle & and will not trigger the obstacle detection switch 103. When the torsional stiffness of the detection beam is greater than or equal to the threshold, the vertical boom 101 will rotate to angle & and will trigger the obstacle detection switch 103.

[0035] To adjust the torsional stiffness of the inner shaft 107 of the vertical boom 101, this invention further improves the existing obstacle removal beam 100. By setting an adjustment mechanism 200 inside the vertical boom 101, the mechanism adjusts the resistance of the vertical boom 101 so that when the obstacle removal beam 100 encounters a small obstacle, it can sweep away the small obstacle through the obstacle removal beam 100 located at the front end of the obstacle detection device. At the same time, the small obstacle has a small torsional stiffness and will not come into contact with the obstacle detection switch 103, so the obstacle detection switch 103 will not be triggered. Furthermore, the obstacle removal beam 100 can use the thrust of the train moving forward to directly sweep the small obstacle away from the track, thus reducing the sensitivity of the obstacle removal beam 100 to obstacles.

[0036] If the mass of the detected obstacle is higher than the set torsional stiffness of the obstacle, the vertical rod 101 fixed to the obstacle removal beam 100 will rotate. At this time, the fixing ring 106 on the vertical rod 101 rotates in the reinforcing plate 104 through the rotating shaft 107. At this time, the inner side of the vertical rod 101 contacts the obstacle detection switch 103, and the normally closed contact in its 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, thereby causing the train to perform emergency braking.

[0037] The adjusting mechanism 200 includes a fixing member 201 disposed on the upper end face of the connecting plate 105, a movable member 202 disposed at one end of the rotating shaft 107 passing through the fixing member 201, an elastic member 203 disposed inside the fixing member 201, the movable member 202 and the elastic member 203 cooperating with each other, and a rotating member 204 and a positioning member 205 disposed inside the fixing member 201. Figures 1 to 6As can be seen, the present invention uses the cooperation of the rotating part 204 and the positioning part 205 to make the moving part 202 and the elastic part 203 cooperate, thereby adjusting the resistance of the rotating shaft 107. In this way, the device can adjust the torsional stiffness of the vertical rod 101 according to the actual situation. When the torsional stiffness is small, the obstacle removal beam 100 can directly sweep small obstacles off the track with the thrust of the train moving forward. When the torsional stiffness is greater than the resistance of the rotating shaft 107, the inner side of the vertical rod 101 contacts the obstacle detection switch 103, thereby enabling the train to perform emergency braking.

[0038] A positioning mechanism 300 is provided between the two sets of obstacle-clearing crossbeams 100. The positioning mechanism 300 includes a connecting member 301 disposed within the two sets of obstacle-clearing crossbeams 100. Each obstacle-clearing crossbeam 100 is provided with a locking member 302. The connecting member 301 and the locking member 302 cooperate with each other. A hollow hole 303 is provided within the obstacle-clearing crossbeam 100. Figures 6 to 10 It can be seen that the present invention simplifies the installation method of the obstacle removal beam 100. By setting one set of obstacle removal beams 100 in the prior art into two sets of modular obstacle removal beams 100, the installation is simpler and more convenient. In this way, the device can effectively realize the basic function of detecting obstacles, and has a simple structure, reliable function, and good practicality, reliability and maintainability.

[0039] Working Principle: In summary, this invention uses the cooperation of the rotating part 204 and the positioning part 205 to make the moving part 202 and the elastic part 203 cooperate, thereby adjusting the torsional stiffness of the rotating shaft 107. In this way, the device can adjust the torsional stiffness of the vertical rod 101 according to the actual situation. When the torsional stiffness is small, the obstacle removal beam 100 can directly sweep small obstacles off the track with the thrust of the train moving forward. When the torsional stiffness is greater than the resistance of the rotating shaft 107, the inner side of the vertical rod 101 contacts the obstacle detection switch 103, thereby enabling the train to perform emergency braking. Furthermore, by simplifying the installation method of the obstacle removal beam 100, by setting one set of obstacle removal beams 100 in the prior art as two sets of modularly connected obstacle removal beams 100, the installation is simpler and more convenient.

[0040] Example 2

[0041] Based on Embodiment 1, the following technical features are added: The fixing member 201 includes a fixing block 201a integrally formed on the upper end face of the connecting plate 105. The fixing block 201a has a cavity 201b, and a conical ring 201c is rotatably connected within the cavity 201b. An annular protrusion 201d is integrally formed on the inner wall of the conical ring 201c, and a conical cavity 201e is provided within the conical ring 201c. The movable member 202 includes a movable plate 202a. One end of the rotating shaft 107, passing through the fixing block 201a, is fixedly connected to the movable plate 202a. The movable plate 202a is provided with… Inside the conical cavity 201e, the movable plate 202a has a notch 202b, and a telescopic plate 202c is rotatably connected inside the notch 202b. The elastic element 203 includes an arc-shaped groove 203a provided in the annular protrusion 201d. A compression spring 203b is fixedly connected inside the arc-shaped groove 203a. A slider 203c is fixedly connected to one end of the compression spring 203b. The slider 203c is correspondingly slidably connected inside the arc-shaped groove 203a. An opening 203d is provided inside the slider 203c. The telescopic plate 202c is correspondingly installed inside the opening 203d.

[0042] Depend on Figures 5 to 6 It can be seen that a circular fixing block 201a is fixedly connected to the upper end face of the connecting plate 105. The fixing block 201a has a cylindrical cavity 201b inside. A conical ring 201c is rotatably connected inside the cavity 201b. A conical cavity 201e is formed inside the conical ring 201c to accommodate the movable plate 202a. An annular protrusion 201d is integrally formed inside the conical cavity 201e. An arc groove 203a is provided inside the annular protrusion 201d. A slider 203c is connected inside the arc groove 203a through a compression spring 203b. The movable plate 202a is located at the position of the conical cavity 201e on the rotating shaft 107. One end of the telescopic plate 202c is rotatably connected inside the notch 202b, and the other end is installed inside the opening 203d. Thus, by rotating the conical ring 201c in the forward or reverse direction, the compression spring 203b is driven to rotate accordingly, thereby changing the resistance of the slider 203c when it moves.

[0043] Therefore, when the vertical boom 101 rotates, it drives the fixed ring 106 to rotate. The fixed ring 106 drives the rotating shaft 107 to rotate within the reinforcing plate 104. At the same time, the rotating shaft 107 drives the movable plate 202a to rotate within the conical cavity 201e. In this way, by changing the resistance of the slider 203c during movement, the sensitivity of the vertical boom 101 during rotation is reduced, so that the obstacle removal beam 100 can directly sweep small obstacles away from the track by using the thrust of the train moving forward.

[0044] Rotating component 204 includes a second opening 204a disposed within the conical ring 201c, the second opening 204a correspondingly communicating with the conical cavity 201e, a positioning block 204b fixedly connected to the inner side of the second opening 204a, an auxiliary block 204c movably connected within the second opening 204a, a curved groove 204d provided on the outer wall of the auxiliary block 204c, the positioning block 204b correspondingly slidably connected within the curved groove 204d, and the positioning component 205 including an auxiliary groove disposed within the auxiliary block 204c.

[0045] 205a, the auxiliary block 204c has a limiting groove 205b on both sides of its outer wall, the top of the inner wall of the cavity 201b is symmetrically fixed with a limiting block 205c, the limiting block 205c is correspondingly located in the limiting groove 205b, the fixing block 201a has a threaded hole 205d, the threaded hole 205d is correspondingly connected to the cavity 201b, the threaded hole is threaded with a screw 205e, the screw 205e is correspondingly rotatably connected in the auxiliary groove 205a;

[0046] Depend on Figures 5 to 6 It can be seen that the conical ring 201c has a cylindrical opening 204a inside, and a square positioning block 204b is fixedly connected to the inside of the opening 204a. A cylindrical auxiliary block 204c is movably connected inside the opening, and an inclined curved groove 204d is provided inside the auxiliary block 204c. The positioning block 204b is correspondingly slidably connected in the curved groove 204d. At the same time, the present invention further defines the structure of the auxiliary block 204c. Vertical limiting grooves 205b are provided on both sides of the auxiliary block 204c, and a long strip-shaped limiting block 205c is fixedly connected to the top of the inner wall of the cavity 201b. The limiting block 205c is correspondingly slidably connected in the limiting groove, and a screw 205e is rotatably connected inside the auxiliary block 204c. Therefore, when the screw 205e rotates downward, The auxiliary block 204c moves vertically downward within the second opening 204a. When it is necessary to adjust the resistance of the slider 203c, simply rotate the screw 205e. The vertical movement of the screw 205e causes the auxiliary block 204c to move vertically within the second opening 204a. Since the positioning block 204b is correspondingly slidably connected within the inclined curved groove 204d, it causes the conical ring 201c to rotate. The forward or reverse rotation of the conical ring 201c causes the compression spring 203b to rotate accordingly, thereby changing the resistance of the slider 203c. This reduces the sensitivity of the vertical rod 101 during rotation, allowing the obstacle removal beam 100 to directly sweep small obstacles off the track using the thrust of the train moving forward.

[0047] Working principle: As shown in Example 1, when it is necessary to adjust the critical value of the impact of the obstacle removal beam 100, the screw 205e is rotated. The vertical movement of the screw 205e drives the auxiliary block 204c to move vertically within the opening 204a. Since the positioning block 204b is correspondingly slidably connected within the inclined curved groove 204d, the conical ring 201c rotates. The forward or reverse rotation of the conical ring 201c drives the compression spring 203b to rotate accordingly, thereby changing the resistance of the slider 203c during movement. This reduces or increases the sensitivity of the vertical rod 101 during rotation. When the sensitivity decreases, the obstacle removal becomes easier. When the crossbeam 100 encounters a small obstacle, it clears the small obstacle through the obstacle removal crossbeam 100 located at the front end of the obstacle detection device. At the same time, the small obstacle has low torsional stiffness, so the vertical rod 101 will not come into contact with the obstacle detection switch 103. If the mass of the obstacle is detected to be higher than the set torsional stiffness of the obstacle, the vertical rod 101 fixed to the obstacle removal crossbeam 100 will rotate. At this time, the fixing ring 106 on the vertical rod 101 rotates in the reinforcing plate 104 through the rotating shaft 107. At this time, the inner side of the vertical rod 101 comes into contact with the obstacle detection switch 103, and its detection information is transmitted to the subway central control system, thereby causing the train to perform emergency braking.

[0048] Example 3

[0049] Based on Embodiment 2, the following technical features are added: The obstacle detection switch 103 provided by the present invention is set at a high position above the track, which improves the working environment of the obstacle detection switch 103, eliminates the need for a protective box, reduces the weight of the device, and achieves the stability of the vertical rod 101 during movement through the rotating shaft 107, which 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 effectively realize the basic function of obstacle detection, and has a simple structure, reliable function, and good applicability, reliability and maintainability.

[0050] It also includes an adjustment plate 114. The mounting plate 102 has a movable hole 115 on its side circumference. A screw 116 is correspondingly provided in the movable hole 115. The screw 116 is correspondingly provided on the adjustment plate 114. A reinforcing seat 117 is integrally formed on one side of the adjustment plate 114. A lifting ring 118 is provided on the reinforcing seat 117. The reinforcing seat 117 is fixedly connected to the bogie at the front of the train.

[0051] Depend on Figures 1 to 4As can be seen, the obstacle detection device provided by the present invention has an adjustable relative height between the adjusting plate 114 and the mounting plate 102. When the height of the detection beam needs to be adjusted, it can be achieved simply by adjusting the relative height between the adjusting plate 114 and the mounting plate 102. Compared with the prior art, maintenance is more convenient.

[0052] Working Principle: In summary, this invention improves the working environment of the obstacle detection switch 103 by placing it at a higher position above the track, eliminating the need for a protective box and reducing the weight of the device. Furthermore, 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, only the position of the screw 116 between the adjusting plate 114 and the mounting plate 102 is required to adjust the relative height between them. This allows for quick adjustment of the vertical position of the detection beam, making maintenance more convenient.

The reinforcing block 109 and the obstacle removal beam 100 are fixed by the screw 113. A positioning mechanism 300 is provided between the two sets of obstacle removal beams 100, so that the two sets of obstacle removal beams 100 are more convenient and stable during installation.

[0056] The docking component 301 includes a fixed seat 301a fixedly connected to the inside of the hollow hole 303. The side wall of the fixed seat 301a is integrally formed with an insert block 301b. The insert block 301b is provided with a corresponding semi-circular groove 301c.
