Description

Technical Field

[0001] This invention belongs to the field of equipment detection trigger signal technology, and specifically relates to a detection trigger device, and more particularly to a fixed detection trigger device. Background Technology

[0002] With the increasing speed of high-speed trains, real-time and rapid testing of the braking system is crucial for ensuring reliable high-speed operation and plays a vital role in train safety. The self-starting of train testing equipment typically requires a corresponding triggering device.

[0003] In practical applications, the triggering devices of existing train detection equipment often suffer from problems such as insufficient reliability and limited adaptability due to reasons such as single-sided installation or insufficient space inside the rail. Especially under complex environmental conditions, it is difficult to meet the requirements of high precision and high stability. (Specifically, the existing triggering device uses a single bracket to be simply installed inside a single rail. Affected by the rail environment, installation status, and the loosening and displacement of the device due to long-term train passage, it often experiences trigger failure or multiple false triggers in actual use.)

[0004] Therefore, it is necessary to design a detection equipment triggering device that is highly reliable and adaptable. Summary of the Invention

[0005] In view of the shortcomings and deficiencies of the existing technology, this utility model discloses a detection triggering device. The device is fixed on the railway track, has strong adaptability, high reliability, accurate triggering, simple structure and small size.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A detection triggering device includes a fixed clamp, a crossbeam, and a trigger. The fixed clamp is symmetrically fixed on the inner and outer sides of the rail. A crossbeam is provided above the fixed clamp. The crossbeam is set along the rail and its height is adjustable. A trigger is installed on the crossbeam. The trigger is electrically connected to the detection equipment. That is, a trigger is set on each of the inner and outer sides of the rail, and the trigger on the outer side of the rail is higher than the trigger on the inner side of the rail.

[0008] Furthermore, the device is installed on one side of the rail.

[0009] Furthermore, the trigger is tilted towards the inside of the rail, with the tilt angle set to 18~22°.

[0010] Furthermore, the fixing fixture includes a track clamping block and a crossbeam support. The crossbeam support is a plate with a vertical oblong hole on its main body. The track clamping block includes a screw, a fixing block, and a nut. The shape of the fixing block conforms to the outer contour of the rail and a screw hole is provided on the fixing block. The screw spans across the bottom of the rail, and both ends of the screw pass through the screw hole and the oblong hole in sequence and are locked from the outside with a nut.

[0011] Furthermore, the crossbeam is fixed to the top of the plate of the crossbeam support, and the crossbeam on the outside of the rail is higher than the crossbeam on the inside of the rail.

[0012] Furthermore, a first guide groove is provided on the side of the crossbeam along its length, and a screw hole is provided on the top platform of the crossbeam support, and the first guide groove is fixed to the screw hole with bolts.

[0013] Furthermore, a second guide groove is provided at the upper end of the crossbeam along its length, and the trigger moves back and forth through the second guide groove to adjust its position.

[0014] Furthermore, the trigger is provided with a slot, and the second guide groove is movably connected to the slot using a T-screw.

[0015] Furthermore, the trigger includes a proximity switch sensor and a sensor bracket, with the proximity switch sensor mounted on the sensor bracket, which is tilted toward the inside of the rail.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) This utility model discloses a fixed detection equipment triggering device installed on a railway rail. It is fixed on both sides of a single railway rail by a fixing block, a combination nut, a screw, and a crossbeam bracket. It is not easy to loosen, the installation state is very stable, and the reliability is high.

[0018] (2) This utility model device can also adapt to difficult installation environments:

[0019] For example, the arrangement of setting one trigger on each side of a single rail is beneficial for adapting to complex environments: many detection devices are installed inside existing rails. If the triggers are concentrated on the inside of the rail, there will often be installation space conflicts or even installation problems. Therefore, this utility model effectively avoids the above problems by setting one trigger on each side of the rail, which facilitates the selection and installation of the device and has strong adaptability.

[0020] For example, when there is insufficient space for the detection equipment to gather on the inside of the rail, the trigger can be moved back and forth along the rail direction through the guide groove at the upper end of the crossbeam until it does not interfere with other equipment, which is highly adaptable.

[0021] (3) The arrangement design of setting one trigger on each side of the single-sided rail increases the accuracy of detection.

[0022] Furthermore, the device of this invention ensures that the triggers can respond normally by designing the outer trigger to be higher than the inner trigger.

[0023] In addition, tilting the trigger at a certain angle can make the sensing and triggering more accurate.

[0024] (4) The device of this utility model can respond quickly when the train wheelset passes by through a non-contact detection method, and achieve accurate triggering of the train passing by. It has high precision and strong stability. (The device of this utility model realizes the non-contact triggering response function through the proximity switch sensor. When the train passes by, the train wheelset passes above the proximity switch sensor, and the device of this utility model triggers the response and outputs a signal. This signal can be used as a basis for subsequent detection equipment to record.)

[0025] (5) The device of this utility model can also be effectively compatible with various detection devices, such as cameras. The device of this utility model can provide accurate timing to capture vehicle photos; for example, it can be used to trigger the hatch of some detection devices. When the train passes by, the hatch is opened to expose the detection device for detection, and it is closed at other times to protect the detection device.

[0026] In summary, this utility model device has the advantages of high reliability, strong adaptability, accurate triggering, simple structure, and small size. It can effectively improve the operating efficiency and safety of railway systems and has important application value. Attached Figure Description

[0038] The present invention will be further described below with reference to embodiments. Example

[0039] Reference Figures 1 to 10 As shown, the detection triggering device in this embodiment is installed on a single-sided rail 1-2, which is distributed on both the inner and outer sides of the single-sided rail 1-2. The detection triggering device is installed on the single-sided rail 1-2 by a fixing clamp 1-3, and a crossbeam 1-4 is configured, on which a trigger 1-5 is installed. When the train wheelset 1-1 passes through the area where the detection triggering device is located, the trigger 1-5 senses the train wheelset 1-1 and outputs a signal.

[0040] Among them, the single-sided rail 1-2 is the application scenario of this device, and the train wheelset 1-1 is the condition required for triggering this device. Therefore, only the content that affects this device is described, and the rest will not be elaborated on.

[0041] The detection triggering device in this embodiment includes a fixed clamp 1-3, a crossbeam 1-4, and a trigger 1-5. When the train wheelset 1-1 passes through the area, it can quickly respond to the trigger and output a signal.

[0042] The fixing clamps 1-3 fix the entire device to the single-sided rail 1-2 and are distributed on the inner and outer sides of the single-sided rail 1-2 to ensure that the entire device will not loosen during long-term use.

[0043] Specifically, the fixing clamps 1-3 are symmetrically arranged on both sides of the single-sided rail 1-2, including the rail clamp block 3-1 and the crossbeam support 3-2.

[0044] The track clamp 3-1 includes a screw 3-13, two identical fixing blocks 3-11, and two sets of identical combination nuts 3-12.

[0045] The fixing block 3-11 is shaped to fit the outline of the rail 1-2, and has screw holes. The screw rod 3-13 spans across the bottom of the rail 1-2 on one side. After the two ends of the screw rod 3-13 pass through the screw holes on the fixing block 3-11, the two ends of the screw rod 3-13 are locked from the outside with combination nuts 3-12, thereby clamping and fixing the two fixing blocks 3-11 on both sides of the rail 1-2 on one side.

[0046] The crossbeam support 3-2 is a plate with a platform at the top for fixing the crossbeam 1-4; the plate body has a vertical oblong hole through which the screw 3-13 (e.g., Figure 3 and Figure 4 As shown, the position of the waist-shaped hole of the main body of the plate is located between the above-mentioned fixing block 3-11 and the combination nut 3-12. The crossbeam bracket 3-2 can adjust the actual height of the crossbeam 1-4 through the waist-shaped hole, thereby adjusting the height of the trigger 1-5.

[0047] There are two sets of crossbeams 1-4, which are fixed to the inner and outer sides of the single-sided rail 1-2 by fixing clamps 1-3 respectively, and the crossbeam 1-4 on the outer side of the rail is higher than the crossbeam 1-4 on the inner side of the rail.

[0048] Specifically, such as Figure 5 and Figure 6 As shown, the crossbeam 1-4 has guide grooves on its sides (set along the length of the crossbeam 1-4), and all parts that need to be installed on the crossbeam 1-4 can be fixed with T-bolts and nuts. Figures 3-4 and Figure 10 As shown, screw holes are provided on the top platform of the crossbeam bracket 3-2, and T-screws are used to fix the side guide groove of the crossbeam 1-4 to the crossbeam bracket 3-2 through the screw holes.

[0049] The crossbeam 1-4 is used to fix and support the trigger 1-5. Specifically, the upper end of the crossbeam 1-4 has a guide groove (set along the length of the crossbeam 1-4), and the trigger 1-5 can be adjusted in position by moving it back and forth appropriately through the upper guide groove. Specifically, as... Figure 10 As shown, a strip hole is provided on the sensor bracket 5-2, and the upper guide groove of the crossbeam 1-4 is fixed to the sensor bracket 5-2 through the strip hole using T-screws.

[0050] When there is insufficient space inside the rail (due to the clustering of detection equipment), triggers 1-5 can be moved back and forth (along the direction of the rail) through the upper guide groove to adjust their position, thus avoiding insufficient space inside the rail.

[0051] Trigger 1-5 is mounted on crossbeam 1-4 and is positioned on the inner and outer sides of rail 1-2 on one side, with the outer trigger 1-5 being higher than the inner trigger 1-5. Trigger 1-5 responds and outputs a signal whenever a train wheelset approaches trigger 1-5.

[0052] Trigger 1-5 includes proximity switch sensor 5-1 and sensor bracket 5-2, with proximity switch sensor 5-1 mounted on sensor bracket 5-2.

[0053] The proximity switch sensor 5-1 is a magnetic induction device. When an iron object passes over it, it will trigger a response and output a signal. In this embodiment, the proximity switch of German TURCK is preferred, model Ni50U-QV40-AP6X2-H1141.

[0054] The function of the sensor bracket 5-2 is to support the proximity switch sensor 5-1 and provide a certain angle of tilt. The tilted proximity switch sensor 5-1 helps to more accurately sense the passing wheelset 1-1. The angle of tilt of the sensor bracket 5-2 is related to the model of the test wheelset 1-1, and the angle range is selected from 18° to 22°, with 20° being the preferred angle.

[0055] like Figure 9 As shown, the installation of triggers 1-5 follows the principle of one on each side of the single-sided rail 1-2, with the outer trigger 1-5 higher than the inner trigger 1-5.

[0056] The arrangement of setting one trigger 1-5 on each side of a single rail 1-2 is beneficial for adapting to complex environments. In the scenarios in which this utility model is applied, many detection devices are often installed inside the rail 1-2. If the triggers 1-5 are concentrated on the inside of the rail 1-2, there will often be installation space conflicts or even installation problems. Therefore, the installation method of setting one trigger 1-5 on each side of the rail effectively avoids such problems and facilitates the site selection and installation of the device.

[0057] When wheelset 1-1 passes by, the outer tread surface is at a higher level than the inner hub. Therefore, this device uses a design where the outer trigger 1-5 is higher than the inner trigger 1-5 to ensure that trigger 1-5 can respond normally. At the same time, the trigger 1-5 is tilted at a certain angle to make the sensing and triggering more accurate. Example

[0058] Unlike Embodiment 1, two or more detection triggering devices as described in Embodiment 1 are set along the length of the single-sided rail 1-2, so that signals can be triggered at different times and stages, thereby enhancing the triggering effect.

[0059] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
