Abstract
Description
Technical Field
[0001] This invention relates to the field of railway rail testing technology, and more specifically, to a visual railway track circuit branch integrated testing device. Background Technology
[0002] Railway rails are the main load-bearing components of railway tracks. They feature an I-shaped cross-section and consist of a rail head, rail web, and rail base. Their functions include guiding wheel movement, distributing loads, and conducting electrical circuits in electrified railway tracks. Modern rails primarily have a flat-bottomed structure for stable placement on sleepers. Historically, Britain used convex-head rails, a design that allowed for rail surface reversal and reuse. Railway tracks, also known as track rails or railway rails, are the guiding and load-bearing structures on railway lines that allow trains to travel. They typically consist of two parallel steel rails fixed to sleepers, beneath which lies the ballast and track bed, secured by fasteners, spikes, and other accessories. Their core functions are guiding train direction, bearing wheel loads, and maintaining smooth operation.
[0003] Currently, existing equipment testing relies on manual mechanical pressurization, which depends on human experience for accuracy and consistency. This often results in insufficient or uneven pressure application due to individual differences in personnel. Furthermore, after manually pressurizing and connecting to the rail, confirmation from the outdoor signal control station via a red light indicator is required to determine if the rail is shunted, making it impossible to directly assess the shunting status on-site. The shunting status of the track circuit cannot be directly determined or identified. Additionally, some existing shunting residual pressure constant pressure testers are bulky, heavy, and inconvenient to carry. Therefore, it is necessary to propose a comprehensive visual railway track circuit shunting test device to address these issues. Summary of the Invention
[0004] To overcome the above shortcomings, this invention provides a visual railway track circuit shunt comprehensive testing device. It aims to improve upon existing equipment testing methods that rely on manual mechanical pressurization, where pressure accuracy and consistency depend on human experience. This often results in insufficient or uneven pressure application due to individual differences in personnel. Furthermore, after manually pressurizing and connecting to the rail, confirmation from the outdoor signal control station via a red light indicator is required to determine if the rail is shunted, making it impossible to directly assess the shunting status on-site. The device also cannot directly determine or identify the track circuit shunt status. Additionally, some existing shunt residual pressure constant pressure testers are large, heavy, and inconvenient to carry.
[0005] This invention is implemented as follows:
[0006] This invention provides a visual railway track circuit branch integrated testing device, including a clamping structure and a pressure structure and a testing instrument mounted on the clamping structure.
[0007] The clamping structure includes a connector, a first clamping member, and a second clamping member. One end of the connector is fixed with a pressure tube, and the other end of the connector has a notch. The first clamping member and the second clamping member are rotatably mounted on the connector via a first connecting member. The pressure structure includes a pressure head, a pressure spring, a pressure sensor, and a second connecting member. One end of the pressure head is fixed with a pressure rod, which slides through the connector and extends to the outside. The pressure spring and the pressure sensor are both sleeved on the pressure rod. The pressure spring is located between the pressure sensor and the pressure head. The pressure sensor is connected to the connector via the second connecting member. The tester includes a housing, a main board, and a display module. A cover is mounted on the top surface of the housing. The main board is installed inside the housing, and two analog modules are mounted on the main board. The display module is installed inside the cover. The pressure sensor is electrically connected to the main board via a wire.
[0008] In one embodiment of the present invention, one end of the pressure tube is provided with an internal thread, and a gland is threaded onto the internal thread.
[0009] In one embodiment of the present invention, the first clamping member includes a connecting frame and a knob. The connecting frame is rotatably engaged with the connecting head, and a pawl is fixed on the connecting frame. A screw is interference-connected to the knob, and the screw thread passes through the pawl.
[0010] In one embodiment of the present invention, the second clamping member includes a connecting plate, which is rotatably connected to the inside of the notch. The connecting plate is integrally formed with a hook claw, and the surface of the hook claw is provided with anti-slip grooves.
[0011] In one embodiment of the present invention, the first connector includes a pin and a first retaining ring, the pin slidingly passing through the connector head, the connector frame, the notch, and the connector plate, respectively, and the first retaining ring engaging with the end of the pin.
[0012] In one embodiment of the present invention, the connector, the notch, the connecting frame, and the connecting plate are provided with round holes that match the pin.
[0013] In one embodiment of the present invention, the second connector includes an anti-detachment plate and a bolt, the anti-detachment plate being sleeved on one side of the pressure sensor, and the bolt being threaded through the anti-detachment plate and connected to one side of the connector.
[0014] In one embodiment of the present invention, the anti-detachment plate has a through hole that matches the side of the pressure sensor and the bolt, the connector has a threaded hole that matches the bolt, the bolt passes through the through hole and is threaded into the threaded hole, the connector also has a positioning hole that matches the pressure rod, the pressure rod slides through the positioning hole, and the upper end of the pressure rod is engaged with a second retaining spring.
[0015] In one embodiment of the present invention, a battery pack is further installed inside the housing, the battery pack is electrically connected to the motherboard, and a socket is electrically installed on one side of the motherboard.
[0016] In one embodiment of the present invention, a left pressure indicator light and a right pressure indicator light are also installed on the housing, and both the left pressure indicator light and the right pressure indicator light are electrically connected to the motherboard.
[0017] The beneficial effects of this invention are as follows: The visual railway track circuit branch circuit integrated testing device obtained through the above design allows for convenient use. During operation, the connecting plate rotates the hook claw, engaging the anti-slip grooves of the hook claw with one side of the rail. Then, the connecting frame rotates the claw to engage it with the other side of the railway rail, simultaneously pressing the pressure head against the top surface of the rail. At this point, the pressure is fine-tuned by rotating the screw with a knob, ensuring the screw end remains firmly against the rail. Pulling the pressure tube extends the pressure rod, and the elasticity of the pressure spring acts on the pressure sensor. The pressure value is displayed on the display module. This allows for convenient fine-tuning of the pressure during clamping. The pressure value, rail surface voltage, current, and track circuit frequency are displayed on the display module. The intelligent standard branch circuit can be interchanged and selected according to different track circuit systems. For example, the pressure ratings are 0.06Ω, 0.50Ω, and 0.25Ω. It also features intelligent visual display and recognition functions with color-coded light strips. Different light strips indicate the rail branch connection status: a red flashing light strip indicates the upward track branch status, and a blue flashing light strip indicates the downward track branch status. It simultaneously collects time, location, and other data, automatically stores and manages the measurement data, and then uploads the measurement analysis data to the backend system via Wi-Fi or Bluetooth. The left and right pressure indicator lights on the tester are used to determine the rail branch connection status, providing a direct visual assessment of whether the rail branch connection is good. During use, the pressure can be easily fine-tuned and maintained, and the pressure value can be displayed, making the applied pressure value more accurate. Furthermore, the tester allows for direct visual judgment. Its overall size is relatively small, making it more convenient to use and carry. Attached Figure Description

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] Example
[0029] Please see Figures 1-7 The present invention provides a technical solution: a visual railway track circuit branch integrated testing device, including a clamping structure 100, a pressure structure 200 and a tester 300 installed on the clamping structure 100.
[0030] Please see Figures 1-4 The clamping structure 100 includes a connector 110, a first clamping member 130 and a second clamping member 140. One end of the connector 110 is fixed with a pressure tube 120, and the other end of the connector 110 is provided with a notch 111. The first clamping member 130 and the second clamping member 140 are rotatably mounted on the connector 110 through the first connector 150.
[0031] One end of the pressure tube 120 has an internal thread, and a gland head 121 is threaded onto the internal thread. The first clamping member 130 includes a connecting frame 131 and a knob 133. The connecting frame 131 is rotatably engaged with the connecting head 110. A claw 132 is fixed on the connecting frame 131. A screw 134 is interference-fitted onto the knob 133, and the screw 134 thread passes through the claw 132. The second clamping member 140 includes a connecting plate 141, which is rotatably connected to the inside of the notch 111. A hook 142 is integrally formed on the connecting plate 141, and the surface of the hook 142 has anti-slip grooves 143. Here, the first clamping member 130 and the second clamping member 140 cooperate to clamp onto the railway rail. The extension and retraction can be adjusted by rotating the knob 133 and the screw 134, which can better fit the railway rail, improve the clamping stability, and allow for fine adjustment of the pressure. The pressure value is then maintained by the claw 132.
[0032] The first connector 150 includes a pin 151 and a first retaining spring 152.

The first connector 150 is used to install the first clamping member 130 and the second clamping member 140, which facilitates rotation and disassembly. The connector 110, the notch 111, the connecting frame 131, and the connecting plate 141 have round holes that match the pin 151 inside.
[0033] Please see Figures 1-4 The pressure structure 200 includes a pressure head 210, a pressure spring 230, a pressure sensor 240, and a second connector 250. One end of the pressure head 210 is fixed with a pressure rod 220, which slides through the connector 110 and extends to the outside. The pressure spring 230 and the pressure sensor 240 are both sleeved on the pressure rod 220. The pressure spring 230 is located between the pressure sensor 240 and the pressure head 210. The pressure sensor 240 is connected to the connector 110 through the second connector 250. Here, the pressure sensor 240 is connected to an external detection device through a connecting wire. By setting the pressure sensor 240, the pressure value can be accurately displayed, improving the accuracy of use.
[0034] The second connector 250 includes an anti-detachment plate 251 and a bolt 252. The anti-detachment plate 251 is sleeved on one side of the pressure sensor 240, and the bolt 252 passes through the anti-detachment plate 251 and is threaded to one side of the connector 110. Here, the second connector 250 can provide stability for the installation of the pressure sensor 240, while one side of the pressure sensor 240 is in close contact with the surface of the connector 110.
[0035] The anti-detachment plate 251 has a through hole that matches the side of the pressure sensor 240 and the bolt 252. The connector 110 has a threaded hole that matches the bolt 252. The bolt 252 passes through the through hole and is threaded into the threaded hole. The connector 110 also has a positioning hole that matches the pressure rod 220. The pressure rod 220 slides through the positioning hole. The upper end of the pressure rod 220 is engaged with a second retaining spring 221.
[0036] Please see Figure 1 , Figure 2 and Figures 4-7 The tester 300 includes a housing 310, a main board 330, and a display module 350. A cover 320 is installed on the top surface of the housing 310. The main board 330 is installed inside the housing 310. Two analog modules 340 are installed on the main board 330. The display module 350 is installed inside the cover 320. The pressure sensor 240 is electrically connected to the main board 330 through a wire.
[0037] The housing 310 houses a battery pack 360, which is electrically connected to the motherboard 330. A socket 331 is electrically installed on one side of the motherboard 330, facilitating connection to an external host computer via Bluetooth or wireless communication for remote control. A red and blue flashing light strip are also installed on the housing 310, both electrically connected to the motherboard 330. These light strips indicate whether the pressure is sufficient, whether the circuit is functioning correctly, and indicate the direction of travel. The simulation module 340 includes a double-row bent pin and a simulation board. The double-row bent pin is electrically connected to the simulation board and mounted on the motherboard 330. The display module 350 includes an LCD screen adapter board and an LCD display screen. The LCD display screen is electrically connected to the LCD screen adapter board and mounted inside the housing cover 320. The tester 300 has wired and wireless interfaces, including Wi-Fi and Bluetooth.
[0038] Specifically, the working principle of this visualized railway track circuit branch integrated testing device is as follows: During use, the hook 142 is rotated via the connecting plate 141, engaging the anti-slip groove 143 of the hook 142 onto one side of the rail. Then, the clamp 132 is rotated via the connecting frame 131, engaging the clamp 132 onto the other side of the railway rail. Simultaneously, the pressure head 210 is in contact with the top surface of the railway rail. At this point, the pressure is finely adjusted by rotating the screw 134 via the knob 133, ensuring the end of the screw 134 is tightly against the railway rail. Then, by pulling the pressure tube 120, the pressure rod 220 extends and retracts. The elasticity of the pressure spring 230 acts on the pressure sensor 240, and the pressure value is displayed via the display module 350. This allows for convenient clamping during operation. The pressure can be finely adjusted. The pressure value can be converted into rail surface voltage, current, and circuit frequency values through the analog module 340 and displayed through the display module 350. It also collects data information such as time and position, automatically stores and manages the measurement data, and then uploads the measurement analysis data to the background system via Wi-Fi or Bluetooth. At the same time, the left and right pressure indicator lights on the tester 300 are used to judge the rail branch connection status, and intuitively judge whether the rail branch connection is good. In this way, the pressure can be easily finely adjusted and maintained during use, and the pressure value can be displayed, making the applied pressure value more accurate. At the same time, the tester 300 can be directly used for visual judgment. The overall size is relatively small, making it more convenient to use and carry.
[0039] It helps to make the clamping more stable and flexible, while being smaller and lighter, making it more convenient to carry and operate.
[0040] The pressure value can be displayed via the simulation module 340 and the display module 350. It also collects data such as time and location, automatically stores and manages the measurement data, and then uploads the analysis data to the backend system via Wi-Fi or Bluetooth. Simultaneously, different colored light strips on the tester 300 display the rail branch connection status: a red flashing light strip indicates the status of the upward track branch, and a blue flashing light strip indicates the status of the downward track branch, allowing for a direct assessment of the rail branch connection's condition. During use, pressure is applied by rotation, and the pressure value is displayed, making the applied pressure more accurate. Furthermore, the tester 300 allows for direct visual assessment and can be folded to reduce its size, making it more intuitive to use and more convenient to carry.
[0041] It should be noted that the specific model and specifications of the pressure sensor 240 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.
[0042] The power supply and operating principle of the pressure sensor 240 are clear to those skilled in the art and will not be described in detail here.
[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
