Description

Technical Field

[0001] The invention relates to the technical field of contact network detection, in particular to a device for detecting rigid-flexible transition characteristics of a rigid contact network. Background Art

[0002] The contact wire is also called the tram line. It is an important component of the contact network. It directly transmits current to the electric locomotive through sliding friction with the pantograph slide on the electric locomotive. Therefore, the contact wire needs to always be in contact with the slide to keep the slide in a stable state of power collection. The contact wire can be divided into flexible contact wire or rigid contact wire according to the flexible suspension or rigid suspension method adopted. A rigid-flexible transition section is usually required at the connection between the rigid contact wire and the flexible contact wire, so that the pantograph can smoothly transition between the two contact wires and maintain stable power collection. The rigid-flexible transition section usually uses an elastic slotted rigid-flexible transition element to make the pantograph transition smoothly, ensuring that the pantograph can continuously and stably collect current when passing through the transition section.

[0003] However, after the rigid-flexible transition section of the contact line is installed, it is usually necessary to conduct an inspection. The existing method for testing the rigid-flexible characteristics of the rigid-flexible transition element is to set test points of equal length on the rigid-flexible transition element, measure the lift amount of each test point by applying a fixed lifting force, and draw a lifting curve. This test method is measured in a static state and is basically entirely manual. It only roughly reflects the motion trajectory, which is inefficient. The reliability of the connection is also difficult to predict. Because the train itself will shake while running, if the slotted transition element does not meet the elasticity requirements, it will be difficult to closely contact the pantograph slide. Conventional testing methods are difficult to simulate the contact between the transition element and the train under shaking conditions, which is relatively inconvenient. In addition, when the train is running, the slide and the contact line must always be in contact with each other to draw power normally. When the contact line contacts the slide, the shaking during the train running, the layout of the ground track, etc., the contact line and the slide may deviate. The contact line here should also be laid out specifically to ensure that the contact line can maintain a more stable contact with the slide and reduce contact line wear. Conventional testing methods are difficult to observe the contact between the contact line and the slide, which is relatively inconvenient. Summary of the Invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Install the contact wire and then use the rail vehicle to pull the main board, so that the main board drives the detection mechanism through the flexible contact wire, the rigid-flexible transition section and the rigid contact wire, and use the current detection equipment to monitor the power supply of the detection mechanism, and use the detection mechanism to take pictures of the contact between the detection mechanism and the contact wire, so as to facilitate the user to understand the contact between the rigid and flexible contact wires and the rigid-flexible transition section and the detection mechanism, and use the detection mechanism to cooperate with the driving mechanism to detect the elasticity of the grooved rigid-flexible transition element, and use the pulling mechanism to detect the flexible contact wire and the rigid contact wire, so as to detect the installation of the rigid and flexible contact wires.

[0021] 2. When the rail vehicle pulls the mainboard to move, the mainboard moves on the track through the track wheels, and the slide contacts the contact line to draw power. The current monitoring device is connected to the slide, and the power supply situation is detected by detecting the current situation on the slide. During the movement of the slide, the contact point between the slide and the contact line can be photographed by a high-speed camera, and the two electric push rods are started to drive the adjacent side plates to rotate. The angle of the high-speed camera is adjusted as needed to capture the contact situation of the slide and the contact line.

[0022] 3. The slide can be driven upward by starting the hydraulic cylinder, thereby adjusting the slide's thrust against the contact line as needed. When the slide moves in the rigid-flexible transition section, the servo motor can be started as needed to drive the turn plate to rotate so that the two bevel gears engage, and then the drive motor is started to drive the screw to rotate through the bevel gear to adjust the position of the moving rod on the turn plate. Then the servo motor is started to drive the turn plate to rotate, so that the turn plate relies on the moving rod, the lifting frame and the connecting frame to drive the slide plate to rotate around the center of the turn plate. When the slide slides on the contact line to collect power, it reciprocates in a circular motion. By monitoring the current on the slide, the elasticity of the grooved transition element in the rigid-flexible transition section of the contact line and the scraping of the slide against the contact line are detected. The two-stroke gasoline engine can also be started to drive the cam to intermittently contact the upper baffle of the rack, so that the rack drives the reeling rod to intermittently reel in the connecting rope through the driven gear, pulling the lifting frame slightly downward. When the cam disengages from the rack, the rack is reset by the reset spring, and the lifting frame is reset by multiple rebound springs, thereby simulating the shaking of the train during travel and detecting the elasticity of the grooved transition element.

[0023] 4. After the hydraulic cylinder is started to drive the slide to move up and contact the contact line, the contact line is located between the two blocks in any rail. Then, the two power motors can be started alternately to drive the adjacent rotating rods to rotate, so that the rotating rod reels in the connecting rope and pulls the block to move, so that the block contacts the contact line, thereby detecting the contact between the flexible contact line and the slide in a shaking state, and detecting the installation status of the rigid contact line.

[0034] Specifically, by using a rail vehicle to pull the main board 100, the main board 100 can be moved on the track through the rail wheel 111 on the connecting box 110. After the contact wire at the rigid-flexible transition end is installed, the main board 100 can be towed by the rail vehicle to move, so that the main board 100 drives the slide 321 on the connecting plate 320 to contact the contact wire, and the slide 321 moves along the contact wire and passes through the rigid-flexible transition section of the contact wire.

One end of the main board 100 can be directly welded to the connecting component for connection to the rail vehicle. The speed of the rail vehicle towing the main board 100 should be slow, so that the user can adjust the driving mechanism 200 and the detection mechanism 300 as needed.

[0035] Example 1

[0036] like Figure 1-Figure 3As shown, in this embodiment, an electric push rod 340 is fixedly connected to the top surface of the connecting frame 310, and the bottom surfaces of the two side panels 330 are fixedly connected to the slide rails 332, and the movable ends of the two electric push rods 340 are respectively slidably engaged in the inside of the two slide rails 332, and the two electric push rods 340 are arranged at an angle, and a plurality of hydraulic cylinders 350 are provided on the bottom surface of the connecting frame 310, and the plurality of hydraulic cylinders 350 are fixedly connected to the driving mechanism 200, and the movable ends of the plurality of hydraulic cylinders 350 are fixedly connected to the bottom surface of the connecting frame 310.

[0037] In this embodiment, the two electric push rods 340 are arranged at an angle, so that when the two electric push rods 340 are extended or retracted, they can slide in the adjacent slide rails 332 through their own moving ends, thereby pulling the two side panels 330 to rotate with one end of themselves as the axis, thereby adjusting the shooting angle of the high-speed camera 331 on the two side panels 330, so that the user can shoot the contact conditions of the contact line and the slide plate 321 at various locations according to the shooting angle of the high-speed camera 331 as needed, and can start multiple hydraulic cylinders 350 to control the lifting height of the slide plate 321 and the resistance of the slide plate 321 to the contact line.

[0038] like Figure 3-Figure 5 As shown, in this embodiment, the driving mechanism 200 includes:

[0039] The frame 210, the rotating plate 220, two sliding frames 230 for limiting the lifting frame 240, the lifting frame 240 for connecting with the detection mechanism 300, the fixed plate 250, the moving rod 260 for adjusting the position of the fixed plate 250 and the lifting frame 240, and the motor box 290, the bottom surface of the frame 210 is fixedly connected to the top surface of the main board 100, the bottom surface center of the rotating plate 220 is rotatably connected to the top surface of the main board 100 and is located inside the frame 210, and the top surface of the rotating plate 220 is provided with a The movable groove is rotatably connected to a screw rod 221 at one end of the movable groove, and one end of the screw rod 221 passes through the outer wall of the rotating plate 220. A servo motor is provided inside the connecting box 110, and the motor shaft of the servo motor is fixedly connected to the center of the bottom surface of the rotating plate 220. The two sliding frames 230 are slidably sleeved inside the frame 210. The two sliding frames 230 are arranged vertically in sequence, and the two sliding frames 230 are slidably connected to the sliding rod 231 inside. The two sliding rods 231 are staggered. The lifting frame 240 is fixed. There are two slide cylinders connected, and the inner side walls of the two slide cylinders are respectively slidably sleeved with the outer side walls of the two slide rods 231. The bottom surface of the lifting frame 240 is fixedly connected with multiple guide rods 241, and multiple hydraulic cylinders 350 are fixedly connected to the lifting frame 240. The top surface of the fixed plate 250 is fixedly connected with multiple sleeves 251. The multiple sleeves 251 correspond to the multiple guide rods 241 one by one. Any guide rod 241 is slidably sleeved inside the adjacent sleeve 251, and the bottom end of the moving rod 260 is slidably engaged in the moving groove. Internally, the top of the moving rod 260 is rotatably connected to the bottom surface of the fixed plate 250, and a threaded hole is opened at the bottom end of the moving rod 260, and the outer wall of the screw 221 is screwed into the threaded hole. The motor box 290 is fixedly connected to the frame 210, and a driving motor is provided inside the motor box 290. One end of the screw 221 and the motor shaft of the driving motor are fixedly sleeved with a bevel gear 201, and a rebound spring 242 is fixedly connected between the bottom end of any guide rod 241 and the inner bottom surface of the adjacent sleeve 251.

[0040] In a specific implementation, the slide bars 231 inside the two slide frames 230 are arranged in an interlaced manner. One slide bar 231 can slide and translate along the long side of the adjacent slide frame 230, and the other slide bar 231 can slide and translate along the short side of the adjacent slide frame 230. The two slide frames 230 can only translate vertically inside the frame body 210, so that the two slide bars 231 can limit the lifting frame 240 through the slide cylinder, so that the lifting frame 240 is not easy to rotate. The servo motor is provided with an electromagnetic brake. When it is not started, the motor shaft will not rotate. When it is started, The servo motor drives the rotating plate 220 to rotate. When the rotating plate 220 rotates to a suitable position, the two bevel gears 201 engage with each other, and then the driving motor is started to drive the screw 221 to rotate through the bevel gear 201, so that the screw 221 adjusts the position of the moving rod 260 in the moving groove, so that the moving rod 260 is separated from the center of the top surface of the rotating plate 220, so that the moving rod 260 drives the fixed plate 250, the lifting frame 240 and the detection mechanism 300 to move synchronously, thereby adjusting the slide plate 300 on the detection mechanism 300. 21 position, so that the slide plate 321 moves horizontally while moving with the main board 100, thereby detecting that when the rotating plate 220 continues to rotate, the rotating plate 220 can drive the moving rod 260 to rotate around the center of the rotating plate 220, so that the moving rod 260 drives the lifting frame 240 and the connecting frame 310 to rotate around the center of the rotating plate 220 synchronously. At the same time, the lifting frame 240 is limited by the two sliding rods 231 so that its two ends are always parallel to the two ends of the frame 210 when rotating around the center of the rotating plate 220, so that the sliding plate on the connecting plate 320 321 synchronously rotates around the center of the rotating plate 220, so that the skateboard 321 is driven by the lifting frame 240 to scrape back and forth horizontally on the contact line during its movement on the contact line. In addition, the skateboard 321 is also driven by the lifting frame 240 to scrape back and forth vertically on the contact line, simulating the shaking situation during the train running, so as to detect whether the elasticity of the grooved rigid-flexible transition element is qualified. If the power supply of the skateboard 321 is always normal during the movement, then the elasticity of the grooved rigid-flexible transition element is basically qualified.

[0041] like Figure 6 As shown, in this embodiment, the pulling mechanism 400 includes:

[0042] Two L-shaped frames 410, two movable plates 420, two rotating rods 430 and multiple rails 440, one end of the short arms of the two L-shaped frames 410 is fixedly connected to the opposite sides of the frame 210, the two movable plates 420 are respectively slidably connected to the long arms of the two L-shaped frames 410, and a support plate is fixedly connected between the two movable plates 420 and the connecting plate 320, the two rotating rods 430 are respectively corresponding to the two movable plates 420, and both ends of any rotating rod 430 are rotatably connected to a plate body, and the two plates on any rotating rod 430 are fixedly connected to the two ends of the corresponding movable plate 420, and the two rotating rods 430 are respectively corresponding to the two movable plates 420. There are multiple connecting ropes 431 arranged between them, and the two ends of any connecting rope 431 are fixedly connected to the outer walls of the two rotating rods 430 respectively, and the multiple rails 440 correspond one to one with the multiple connecting ropes 431. There are two blocks 441 slidingly clamped inside any rail 440, and any connecting rope 431 passes through the two blocks 441 on the corresponding rail 440 and is fixedly connected to the two blocks 441. One end of the two movable plates 420 is fixedly connected to a power box 450, and a power motor is provided inside any power box 450. The motor shaft of any power motor is fixedly connected to one end of the adjacent rotating rod 430.

[0043] In a specific implementation, when the hydraulic cylinder 350 is started to control the height of the slide 321, the connecting plate 320 can synchronously drive the two movable plates 420 to move through the support plate, and the contact line is located between the two blocks 441 in the same rail 440. When the slide 321 contacts the contact line, the connecting ropes 431 between the two rotating rods 430 are in a relaxed state. By starting any power motor, the adjacent rotating rod 430 can be driven to rotate, so that the rotating rod 430 can reel in multiple connecting ropes 431, so that the connecting ropes 431 pull the adjacent blocks 441 to contact the contact line. The two power motors can be started alternately to make the blocks 441 reciprocate and contact both sides of the contact line. When the connecting plate 320 moves in the flexible contact line part, the block 441 can be used to abut against the contact line to cause shaking, thereby simulating the shaking of the flexible contact line in windy weather, so as to detect the power supply of the slide plate 321 when the flexible contact line shakes. When moving to the rigid contact line, the installation firmness of the rigid contact line can be detected by the abutment of the block 441. When testing the replacement of the contact line, the position of the block 441 can be adjusted by stopping the traction of the main board 100 and then starting the power motor to reel in the connecting rope 431, so that the contact line part to be tested is located between the two blocks 441 on the same rail 440.

[0044] Example 2

[0045] On the basis of the first embodiment, the train shaking can be simulated by setting the pull rope 273 .

[0046] like Figure 4-Figure 5As shown, in this embodiment, a U-shaped plate 270 is fixedly connected to the bottom surface of the fixed plate 250, and a winding rod 271 is rotatably connected between the two arms of the U-shaped plate 270, and a plurality of pull ropes 273 are fixedly wound around the outer wall of the winding rod 271, and one end of any pull rope 273 is fixedly connected to the bottom surface of the fixed plate 250, and a drive box 222 is fixedly connected to the top surface of the rotating plate 220, and a two-stroke gasoline engine is arranged inside the drive box 222, and a cam 223 is fixedly sleeved on the output end of the two-stroke gasoline engine, and a driven gear 272 is fixedly sleeved on one end of the winding rod 271, and a clamping strip is fixedly connected to one end of the U-shaped plate 270, and the clamping strip is slidably clamped with a rack 280, and the rack 280 is meshed with the driven gear 272, and both ends of the rack 280 are fixedly connected to baffles, wherein a plurality of return springs 281 are fixedly connected between one baffle and the U-shaped plate 270.

[0047] In specific implementation, the lifting frame 240 is supported on the fixed plate 250 by multiple rebound springs 242. By starting the two-stroke gasoline engine to drive the cam 223 to rotate, the protrusion of the cam 223 intermittently contacts another baffle on the rack 280, thereby moving the rack 280 and rubbing the driven gear 272 and the winding rod 271 to rotate, so that the winding rod 271 synchronously reels multiple connecting ropes 431, so that the connecting ropes 431 pull the lifting frame 240 slightly toward the fixed plate 250. Then, when the cam 223 is separated from the baffle, the rack 280 is driven to reset by the multiple return springs 281, thereby driving the winding rod 271 to release the connecting ropes 431. At the same time, the multiple rebound springs 242 push the lifting frame 240 up and reset, so that the slide plate 321 moves slightly up and down to simulate the shaking state of the train when it is running, thereby detecting the power supply situation of the slide plate 321 in the rigid-flexible transition section in the shaking state, thereby detecting whether the elasticity of the grooved rigid-flexible transition element is qualified.
