Description

Technical Field

[0001] The present invention relates to the technical field of track electrical parameter measurement, in particular to a track electrical parameter automatic measurement device. Background Art

[0002] Track electrical parameters refer to electrical parameters related to the working status and performance of track circuits. Track electrical parameters mainly include the voltage between two rails and the current passing through each rail. The track circuit is composed of the rail line and rail insulation connected to the power transmission and receiving equipment. It forms an integral part with the signal machine and relay, and can automatically and continuously detect whether there is a train occupying this section of the circuit. By measuring the voltage and current of the track circuit, we can understand the track circuit's responsiveness to signals and transmission efficiency.

[0003] When measuring track current, a clamp ammeter can be used to clamp the rail for measurement. When measuring the voltage between two rails, the two terminals of the multimeter can be connected to the rails at corresponding positions for measurement. However, the above measurement methods generally require manual handheld measuring instruments to measure, which is not conducive to improving the measurement efficiency of track electrical parameters. In addition, rusted and oxidized rails will increase the resistance in the track circuit, and cracks at the connection positions of adjacent rails will also block the current from passing through the rails. These factors will cause abnormal current measurement values ​​in the track circuit. It is not easy to overcome the above factors affecting the measurement results at the same time during the track electrical parameter measurement process. Summary of the Invention

[0004] The purpose of the present invention is to provide a device for automatically measuring track electrical parameters to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A track electrical parameter automatic measuring device, comprising:

[0007] The measuring vehicle includes a carrier plate, and a first shaft and two second shafts are respectively rotated at the bottom of both ends of the carrier plate, and moving wheels are fixed to both ends of the first shaft and one end of the second shaft;

[0008] Two current measuring components are provided at one end of the carrier plate. The current measuring components include a second electric push rod. The output end of the second electric push rod is fixed to a first box. A clamp ammeter is fixed inside the first box.

[0009] A voltage measuring component is fixed to the bottom of the carrier plate. The voltage measuring component includes a box body 2 and two electric push rods 3. A multimeter is fixed inside the box body 2. The two detection lines of the multimeter are respectively fixed to the output ends of the corresponding positions of the electric push rods 3;

[0010] The annular plate is rotatably connected to the top surface of the carrier plate, and a plurality of lapping members are evenly placed on the top surface of the annular plate;

[0011] There are two pick-and-place assemblies, both of which are fixed on the top surface of the carrier plate and are used to place the lapping members at the open circuit or rust position on the rail;

[0012] The flaw detection assembly is installed above the carrier plate and cooperates with the measuring vehicle to move and detect the open circuit or rust position of the rail.

[0013] Furthermore, a movable seat that is slidably clamped to the carrier plate is rotatably sleeved outside the second shaft rod. A rectangular cover is fixed above the movable seat on the top surface of the carrier plate, and an airbag is fixed inside the rectangular cover.

[0014] Furthermore, a first electric push rod is inserted and fixed at one end of the carrier plate, and a support plate is fixed at the output end of the first electric push rod.

[0015] Furthermore, a plurality of rectangular grooves are evenly formed on the top surface of the annular plate. The lapping member includes a connecting plate, and U-shaped plates are fixed at both ends of the connecting plate.

[0016] Furthermore, a driving motor capable of driving the annular plate to rotate is embedded and fixed at one end of the carrier plate, and a support ring rotatably connected to the annular plate is fixed at the top of the carrier plate.

[0017] Furthermore, two measuring clamps are rotated at one end of the clamp-on ammeter. A拨动块 (it should be a specific part name, please check and correct if wrong) is rotatably installed outside the clamp-on ammeter, and a motor for driving the拨动块 to rotate is fixed inside the first box body.

[0018] Furthermore, a support shell is fixed at the bottom of the carrier plate, and a first reduction motor for driving the first shaft rod to rotate is fixed on the support shell.

[0019] Furthermore, the pick-and-place assembly includes an L-shaped column fixed on the carrier plate. The output end of the L-shaped column is fixed with a fourth electric push rod, and an electromagnet is fixed at the output end of the fourth electric push rod.

[0020] Furthermore, a circular plate and a circular cover are fixed between the two L-shaped columns, and rectangular holes are formed through both ends of the annular plate.

[0021] Furthermore, the flaw detection assembly includes:

[0022] A second reduction motor is fixed on the top of the circular plate. Both output ends of the second reduction motor are fixed with connecting shafts;

[0023] [[ID=;39]]There are two winding wheels, which are respectively fixed to the connecting shafts at corresponding positions. A first cable is wound and fixed outside the winding wheels;

[0024] Cable 2, two in number, electrically connected to cable 1 at corresponding positions;

[0025] The electric push rod 5 is used to drive the end of the cable 2 to contact the rail.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. By moving the measuring vehicle to the two rails of the track circuit, the motor output end drives the part of the eccentric wheel away from the center of the circle to rotate and squeeze the toggle block on the clamp ammeter. The rotation of the toggle block causes the two measuring clamps on the clamp ammeter to rotate and unfold. The second output end of the electric push rod drives the clamp ammeter downward, so that the two measuring clamps clamp the rails, realizing automatic measurement of the current flowing on the rails. The measuring vehicle can move with the two clamp ammeters to measure the track current at different positions on the rails, which is conducive to improving the measurement efficiency of the track current.

[0028] 2. By extending the output ends of the two electric push rods, the detection pen on the multimeter automatically moves toward the rail. After the two detection pens come into contact with the rails at different positions, the multimeter can measure the rail surface voltage between the two rails, which is convenient for understanding the transmission performance and signal strength of the track circuit. Similarly, the measuring vehicle can move the two detection pens to different positions on the rail to measure the rail surface voltage, which is beneficial to improve the measurement efficiency of the rail voltage.

[0029] 3. By rotating an annular plate on the top of the measuring vehicle, a plurality of lap joints are placed on the surface of the annular plate. When the measuring vehicle encounters rust on the surface of the rail or a fracture at the joint of the rail, the annular plate rotates to rotate the lap joint to the bottom of the four output ends of the electric push rod. The four output ends of the electric push rod extend and use an electromagnet to adsorb and fix the lap joint. Then, the rectangular hole position of the annular plate is rotated to the bottom of the four output ends of the electric push rod. The four output ends of the electric push rod extend again to put the lap joint plate on the rust or crack position of the rail. The lap joint is used to reconnect the broken position of the rail and then the current and voltage are measured. In this way, the influence of rail corrosion or fracture on the measurement results can be overcome in the process of measuring track voltage and current.

[0030] 4. Move the support plate upward through the output end of the electric push rod, so that the two shaft rods 2 are connected together through the support plate. At this time, the two shaft rods 2 on the measuring vehicle and the moving wheels at the ends of the shaft rods 2 simulate the wheelset of the train (the wheelset is the two wheels arranged opposite to each other on the train. The train wheelset is a conductor with very small resistance. When the train runs on the rails, the track circuit is short-circuited, and the current is redirected to the train axle. The track current will not flow through the relay. After the relay loses current, it loses magnetism, releases the armature, and the rear contacts close, connecting the red light circuit of the signal machine, warning that the track is occupied). The current and voltage measured by the moving measuring vehicle are the electrical parameters under the track circuit short-circuit condition.

[0031] 5. The output end of the electric push rod is moved downward with the support plate, so that the two shaft rods are no longer connected to transmit current through the support plate. The shaft rod is made of insulating material. At this time, the measuring vehicle moves on the rail without breaking the track circuit. The current and voltage measured by the measuring vehicle are the electrical parameters of the track circuit when it is static, which is convenient for automated measurement of the electrical parameters of the track circuit under different working conditions. The different electrical parameters measured are compared with the standard values, which is convenient for accurately understanding the response capability and transmission efficiency of the track circuit to signals.

DETAILED DESCRIPTION

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] For example 1, please refer to Figure 1 - Figure 8In an embodiment of the present invention, a device for automatically measuring track electrical parameters includes a measuring vehicle 100. The measuring vehicle 100 includes a carrier plate 110. A shaft rod 120 and two shaft rods 130 are respectively rotated at the bottoms of both ends of the carrier plate 110. Both ends of the shaft rod 120 and one end of the shaft rod 130 are fixed with moving wheels. Two current measuring components 200 are fixedly mounted on one end of the carrier plate 110. The current measuring components 200 include an electric push rod 210. The output end of the electric push rod 210 is fixed with a box 1 220. A clamp ammeter 230 is fixed inside the box 1 220. A voltage measuring component 300 is fixedly installed on the bottom of the carrier plate 110, and the voltage measuring component 300 includes a box body 2 310 and two electric push rods 3 320. A multimeter is fixed inside the box body 2 310, and the two detection lines of the multimeter are respectively fixed to the output ends of the electric push rods 3 320 at corresponding positions. A ring plate 400 is rotated on the top surface of the carrier plate 110, and a plurality of lap joints 410 are evenly placed on the top surface of the ring plate 400. Two pick-and-place components 500 are fixed on the top surface of the carrier plate 110, and the pick-and-place components 500 are used to place the lap joints 410 at the broken or rusted position on the rail.

[0043] Specifically, by installing a clamp ammeter 230 on the measuring vehicle 100, the output end of the electric push rod 210 can adjust the height position of the clamp ammeter 230, and the motor 240 can drive the measuring clamp 231 on the clamp ammeter 230 to automatically open and connect to the rail, so as to automatically measure the current flowing through the rail. By fixing a multimeter at the bottom of the measuring vehicle 100, the output end of the electric push rod 320 can be connected to the rail with the detection pen 330 on the multimeter, so as to automatically measure the voltage between the two rails. By comparing the measured electrical parameters with the standard electrical parameters, the user can determine whether the measured electrical parameters are consistent with the standard electrical parameters. The parameters are the same to judge the rail's response ability to signals and transmission efficiency. When the outer layer of the rail is oxidized and rusted or cracks appear at the connection position, in order to prevent the track circuit from being broken and affecting the electrical parameters of the remaining positions of the track, the output end of the electric push rod 520 is equipped with an electromagnet to adsorb and fix the bridging piece 410. After the electromagnet is powered off, the bridging piece 410 is released to the damaged position on the track, so that the bridging piece 410 replaces the damaged position of the track to conduct the rail and transmit current, thereby achieving the process of measuring the track voltage and current. Overcoming the influence of rail corrosion or fracture factors on the measurement results.

[0044] like Figure 5 and Figure 6As shown, in this embodiment, an activity seat 131 that is slidably clamped to the carrier plate 110 is rotatably sleeved on the outer side of the second shaft rod 130. A rectangular cover 112 is fixed above the activity seat 131 on the top surface of the carrier plate 110. An airbag is fixed inside the rectangular cover 112. When the electric push rod four 520 drops the overlapping piece 410 onto the rusty position on the rail, as the measuring vehicle 100 moves along the rail, the moving wheels on the second shaft rod 130 will roll onto the overlapping piece 410. The moving wheels that roll onto the overlapping piece 410 will carry the second shaft rod 130 upward. Then, the second shaft rod 130 squeezes the airbag inside the rectangular cover 112 through the activity seat 131. The airbag facilitates adapting to the up-and-down movement of the second shaft rod 130 and the moving wheels when passing through the overlapping piece 410, enabling the measuring vehicle 100 to stably cross the overlapping piece 410.

[0045] As Figure 5 shown, in this embodiment, there is a gap at the ends of the two second shaft rods 130. Each second shaft rod 130 can move up and down with the moving wheels at its respective end, preventing the measuring vehicle 100 from jolting when passing through the overlapping piece 410 on the rail to a certain extent.

[0046] As Figure 5 shown, in this embodiment, an electric push rod one 140 is inserted and fixed at one end of the carrier plate 110. A support plate 141 is fixed at the output end of the electric push rod one 140. When the output end of the electric push rod one 140 contracts, the two second shaft rods 130 can be connected together through the support plate 141. The materials of the second shaft rod 130 and the support plate 141 are both conductive materials, enabling the two moving wheels, the two second shaft rods 130, and the support plate 141 to simulate the wheelset of a train. When the output end of the electric push rod one 140 extends, the two second shaft rods 130 are separated. When the measuring vehicle 100 moves on the track circuit of the rail, it will not cause a short circuit in the track circuit. At the same time, the two mutually separated second shaft rods 130 can move up and down independently with the moving wheels, enabling the measuring vehicle 100 to stably move to measure electrical parameters.

[0047] As Figure 6 shown, in this embodiment, a plurality of rectangular grooves are evenly formed on the top surface of the annular plate 400. The overlapping piece 410 includes a connecting plate, and U-shaped plates are fixed at both ends of the connecting plate. The rectangular grooves are arranged in an annular and equiangular manner on the annular plate 400. The rectangular grooves facilitate accommodating and placing the overlapping piece 410. The annular plate 400 can rotate the overlapping piece 410 to different positions below the output end of the electric push rod four 520, facilitating the use of the electric push rod four 520 to install the overlapping piece 410 on the outer side of the rail at different positions. During the installation of the overlapping piece 410, the U-shaped plates are sleeved on the rail. Among them, the material of the overlapping piece 410 is a conductive material, facilitating reconnecting the positions on the rail where the current is not connected.

[0048] As Figure 5 and Figure 6As shown, in this embodiment, a driving motor 150 capable of driving the annular plate 400 to rotate is embedded and fixed at one end of the carrier plate 110, a gear is fixed at the output end of the driving motor 150, a gear ring 420 is fixed on the inner ring side of the annular plate 400, and the gear ring 420 is engaged with the gear for transmission, a support ring 111 rotatably connected to the annular plate 400 is fixed on the top of the carrier plate 110, and an annular groove rotatably connected to the support ring 111 is fixed on the bottom surface of the annular plate 400.

[0049] In this embodiment, the driving motor 150 rotates the gear, and the gear ring 420 that is engaged with the gear drives the annular plate 400 to rotate on the carrier plate 110, so that the annular plate 400 can first rotate the bridging piece 410 to the bottom of the output end of the electric push rod 4 520, and the output end of the electric push rod 4 520 absorbs and picks up the bridging piece 410, and then the annular plate 400 rotates the rectangular hole to the bottom of the output end of the electric push rod 4 520, so that the output end of the electric push rod 4 520 can carry the bridging piece 410 through the rectangular hole to clamp the bridging piece 410 and place it on the rail.

[0050] In this embodiment, after the electrical parameter measurement of the measuring vehicle 100 is completed, the measuring vehicle 100 can be moved in the opposite direction along the rail. At this time, the annular plate 400 first rotates the rectangular hole to the bottom of the output end of the electric push rod 4 520. The output end of the electric push rod 4 520 can move down to adsorb and fix the lap joint 410 on the rail, and then move the lap joint 410 to the top of the annular plate 400. Then the annular plate 400 rotates the rectangular groove to the position below the lap joint 410, so that the electric push rod 4 520 can store the used lap joint 410 inside the rectangular groove of the annular plate 400.

[0051] like Figure 4 As shown, in this embodiment, one end of the clamp ammeter 230 has two measuring clamps 231 that are rotatable, and a toggle block 232 is rotatably installed on the outer side of the clamp ammeter 230. A motor 240 for driving the toggle block 232 to rotate is fixed inside the box body 220, and an eccentric wheel 241 arranged eccentrically is fixed to the output end of the motor 240. The rotation of the motor 240 with the eccentric wheel 241 will cause the eccentric wheel 241 to squeeze the toggle block 232, and the movement of the toggle block 232 toward the inside of the clamp ammeter 230 will cause the two measuring clamps 231 to rotate and unfold. After the eccentric wheel 241 rotates and drives away from the toggle block 232, the toggle block 232 can automatically rotate and move out of the clamp ammeter 230, and at the same time, the two measuring clamps 231 are merged. The linkage relationship between the measuring clamp 231 and the toggle block 232 is a well-known structure of the clamp ammeter 230 of the prior art, and the specific working principle of the clamp ammeter 230 will not be described in detail.

[0052] like Figure 3 and Figure 5As shown, in this embodiment, a support shell 160 is fixed to the bottom of the carrier board 110. A reduction motor 161 for driving the first shaft rod 120 to rotate is fixed to the support shell 160. The output end of the reduction motor 161 drives the first shaft rod 120 to rotate. The first shaft rod 120 drives two moving wheels to roll on the steel rail, so as to realize the movement of the measuring vehicle 100 on the steel rail and measure the electrical parameters.

[0053] In this embodiment, a limiting ring is fixed to one side of each moving wheel. The limiting ring can prevent the moving wheel from disengaging from the steel rail. Among them, there is a gap between the limiting ring on the limiting wheel at the end of the second shaft rod 130 and the steel rail, and this gap allows the U-shaped plate of the overlapping part 410 to pass through.

[0054] As Figure 3 and Figure 6 shown, in this embodiment, the picking and placing component 500 includes an L-shaped column 510 fixed to the carrier board 110. An electric push rod 520 is fixed to the output end of the L-shaped column 510. An electromagnet is fixed to the output end of the electric push rod 520. When the electromagnet is powered on, it has magnetism and can adsorb and fix the overlapping part 410. When releasing the overlapping part 410, the electromagnet is powered off to lose its magnetism, so as to release the adsorbed and fixed overlapping part 410.

[0055] As Figure 1 、 Figure 3 and Figure 6 shown, in this embodiment, a circular plate 511 and a circular cover 512 are fixed between the two L-shaped columns 510. The circular cover 512 is located above the circular plate 511 and plays a protective role. Rectangular holes are respectively formed through both ends of the annular plate 400, and the rectangular holes facilitate the passing of the overlapping part 410.

[0056] As Figure 2 shown, in this embodiment, when cracks appear at the connection position of adjacent steel rails, the overlapping part 410 can be installed above the cracks, so that the connecting plate of the overlapping part 410 replaces the cracked position of the steel rail to connect the broken steel rail and conduct electricity.

[0057] As Figure 1 shown, in this embodiment, two L-shaped beams 170 for fixing the second electric push rod 210 are fixed to one end of the carrier board 110. The L-shaped beams 170 are slidably clamped with the first box body 220.

[0058] Embodiment 2: On the basis of Embodiment 1, in order to use two electrical parameter automatic measuring devices to jointly detect the open circuit position of the track circuit, and at the same time realize that the two electrical parameter automatic measuring devices approach each other and move from both ends of the track and synchronously measure the electrical parameters, so as to improve the efficiency of measuring the electrical parameters at different positions of the steel rail.

[0059] As Figure 2 、 Figure 3 and Figure 7As shown, in this embodiment, the flaw detection component 600 includes a reduction motor 2 610 fixedly connected to the circular plate 511, and the two output ends of the reduction motor 2 610 are fixed with a connecting shaft, and the outer side of the connecting shaft is sleeved and fixed with a winding wheel 620, and the outer side of the winding wheel 620 is wound and fixed with a cable 1 630, and one end of the cable 1 630 is connected and fixed with a cable 2 640, and one end of the cable 2 640 passes through the carrier 110, and the bottom of the carrier 110 is fixed with a connecting rod 1 340, and the bottom end of the connecting rod 1 340 is fixed with an electric push rod 5 650, and the electric push rod 5 650 is used to drive the end of the cable 2 640 to contact the rail.

[0060] In this embodiment, a connecting rod 2 660 is fixed to the bottom of the carrier 110, and an electric push rod 5 650 is fixed to the bottom of the connecting rod 2 660. A contact block 641 is electrically connected to a position where the cable 2 640 and the output end of the electric push rod 5 650 are fixed. The contact block 641 is used to connect the cable 2 640 to the rail. The end of the cable 2 640 facing away from the contact block 641 is electrically connected to a rotating column. The cable 1 630 passes through one end of the winding wheel 620 and is fixed with a ring 631. The rotating column is rotatably connected to the ring 631, so that the cable 2 640 does not rotate during the rotation of the winding wheel 620 and can be electrically connected to the cable 1 630.

[0061] like Figure 8 As shown, in this embodiment, when the measuring vehicle 100 has not moved onto the rails of the track circuit, a normal track circuit is one in which the two rails serve as conductors to keep the circuit connected. At this time, the track current flows through the relay 800, and the relay 800 is energized to generate magnetism, which attracts the armature and closes the front contact, connecting the green light circuit of the signal machine, causing the track circuit to light up green.

[0062] like Figure 2 As shown, in this embodiment, insulating joints are installed and fixed at both ends of the rails in the closed section of the track circuit, so that the track circuit is in a closed section.

[0063] Specifically, if the track circuit lights up red in the initial state, it means that there is a local circuit break in the two rails. The specific cause of the circuit break may be rust or cracks. When it is necessary to use a measuring device to automatically detect the circuit break location, a measuring vehicle 100 is arranged at both ends of the rails in the same track circuit. The cables 1 630 on the two measuring vehicles 100 are connected, and the output end of the electric push rod 5 650 is connected to the contact block 641 on the cable 2 640 with the rail. Refer to the instructions. Figure 8The cable 1 630 of the two measuring vehicles 100 short-circuits the longer rail. There is a break in the rail at this distance, for example, the wavy line is the break. At this time, the track circuit is in a connected state and the green light is on. Then the two measuring vehicles 100 are moved closer to each other. The reduction motor 2 610 fixed on the circular plate 511 drives the winding wheel 620 to rotate and rewind the excessive cable 1 630 between the two measuring vehicles 100. When the measuring vehicle 100 moves over the break, the rail is broken again and the track circuit will light up again. The red light indicates that the contact block 641 on the measuring vehicle 100 has passed the disconnection position, that is, the disconnection position has moved to the position between the two moving wheels. Then the pick-up and place assembly 500 can be used to connect the connecting piece 410 to the detected disconnection position to connect the disconnected rail. In this process, the two pick-up and place assemblies 500 can release the connecting pieces 410 one by one to further determine which rail is disconnected. After releasing the connecting piece 410, the green light on the track circuit indicates that the short-circuit position has been found correctly.
