Description

Technical Field

[0001] The 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 state 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 a circuit consisting of rail lines and rail insulation connected to power transmission and receiving equipment. It is integrated with signal machines and relays and can automatically and continuously detect whether this circuit is occupied by trains. By measuring the voltage and current of the track circuit, the response capability and transmission efficiency of the track circuit to signals can be understood.

[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 that affect 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 track electrical parameter automatic measuring device 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 comprises a carrier plate, at the bottom of both ends of the carrier plate, a shaft rod 1 and two shaft rods 2 are respectively rotated, and both ends of the shaft rod 1 and one end of the shaft rod 2 are fixed with moving wheels;

[0008] Two current measuring parts are arranged at one end of the carrier plate, and the current measuring parts include a second electric push rod, a box body 1 is fixed to the output end of the second electric push rod, and a clamp ammeter is fixed inside the box body 1;

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

[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 on the top of the carrier plate.

[0017] Furthermore, two measuring clamps are rotatably arranged at one end of the clamp-on ammeter, a拨动 block is rotatably installed outside the clamp-on ammeter, and a motor for driving the拨动 block 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. A fourth electric push rod is fixed at the output end of the L-shaped column, 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, and connecting shafts are fixed at both output ends of the second reduction motor;

[0023] There are two winding wheels, which are respectively fixed to the connecting shafts at the 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 respectively;

[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, thereby automatically measuring the current flowing through 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 beneficial to improving the measurement efficiency of the track current.

[0028] 2. The output ends of the two electric push rods are extended to make the detection pen on the multimeter automatically move toward the rail. After the two detection pens are in 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 track 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 break in 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 disconnected position of the rail and then measure the current and voltage. In this way, the influence of rail corrosion or breakage on the measurement results can be overcome in the process of measuring the track voltage and current.

[0030] 4. Move the support plate upward through the output end of the electric push rod 1, 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 diverted to the train axle. The track current will not flow through the relay. After the relay loses current, it loses magnetism and releases the armature. The rear contacts are closed, connecting the red light circuit of the signal machine, warning that the track is in an occupied state), so that the current and voltage measured by the moving measuring vehicle are the electrical parameters under the condition of short-circuit of the track circuit.

[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 moving 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 accurate understanding of the track circuit's response capability to signals and transmission efficiency.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0042] For example, see Figure 1 - Figure 8In an embodiment of the present invention, a track electrical parameter automatic measuring device includes a measuring vehicle 100, the measuring vehicle 100 includes a carrier plate 110, and the bottoms of both ends of the carrier plate 110 are respectively rotated with an axle rod 120 and two axle rods 130, both ends of the axle rod 120 and one end of the axle rod 130 are fixed with moving wheels, one end of the carrier plate 110 is fixed with two current measuring parts 200, the current measuring part 200 includes an electric push rod 210, the output end of the electric push rod 210 is fixed with a box body 120, and a clamp ammeter 230 is fixed inside the box body 120 A voltage measuring device 300 is fixedly installed at the bottom of the carrier plate 110, and the voltage measuring device 300 includes a box body 2 310 and two electric push rods 320. A multimeter is fixed inside the box body 2 310, and two detection lines of the multimeter are respectively fixed to the output ends of the electric push rods 320 at corresponding positions. An annular plate 400 is rotatably arranged 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 annular plate 400. Two pick-and-place assemblies 500 are fixed on the top surface of the carrier plate 110, and the pick-and-place assemblies 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 sleeve onto 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, and compare whether the measured electrical parameters are consistent with the standard electrical parameters. The parameters are the same to judge the rail's responsiveness 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 4520 is equipped with an electromagnet to adsorb and fix the lap joint 410. After the electromagnet is powered off, the lap joint 410 is released to the damaged position on the track, so that the lap joint 410 replaces the damaged position of the track to conduct the rail to transmit current, thereby achieving the process of measuring the track voltage and current. Overcoming the influence of rail corrosion or breakage 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 outside 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 places the overlapping part 410 on the rusty position of 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 part 410. The moving wheels that roll onto the overlapping part 410 will drive the second shaft rod 130 to move upward. Then, the second shaft rod 130 squeezes the airbag inside the rectangular cover 112 through the activity seat 131. The airbag facilitates the up-and-down movement of the second shaft rod 130 and the moving wheels when passing through the overlapping part 410, enabling the measuring vehicle 100 to stably cross the overlapping part 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 to a certain extent when passing through the overlapping part 410 on the rail.

[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 short-circuit the track circuit. At the same time, the two 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 part 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 the accommodation and placement of the overlapping part 410. The annular plate 400 can rotate the overlapping part 410 to different positions below the output end of the electric push rod four 520, facilitating the installation of the overlapping part 410 on the outside of the rail at different positions by using the electric push rod four 520. During the installation of the overlapping part 410, the U-shaped plate is sleeved on the rail. Among them, the overlapping part 410 is made of a conductive material, facilitating the reconnection of the non-connected positions of the current on the rail.

[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, the gear ring 420 meshes 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 with the gear, and the gear ring 420 meshing 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 lap joint 410 to the bottom of the output end of the electric push rod 520, and the output end of the electric push rod 520 absorbs and picks up the lap joint 410, and then the annular plate 400 rotates the rectangular hole to the bottom of the output end of the electric push rod 520, so that the output end of the electric push rod 520 can carry the lap joint 410 through the rectangular hole to clamp the lap joint 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 below the output end of the electric push rod four 520. The output end of the electric push rod four 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 four 520 can store the used lap joint 410 into the rectangular groove of the annular plate 400.

[0051] like Figure 4 As shown, in the present embodiment, one end of the clamp meter 230 has two measuring clamps 231 rotatably mounted, and a toggle block 232 is rotatably mounted on the outer side of the clamp meter 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 into the clamp meter 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 meter 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 known structure of the clamp meter 230 of the prior art component, and the specific working principle of the clamp meter 230 is not 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 plate 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 C-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 assembly 500 includes an L-shaped column 510 fixed to the carrier plate 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. The electromagnet has magnetism when energized 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 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 a crack appears at the connection position of adjacent steel rails, the overlapping part 410 can be installed above the crack, so that the connecting plate of the overlapping part 410 replaces the crack 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 plate 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 the mutual approach movement of the two electrical parameter automatic measuring devices 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 connecting shafts, and a winding wheel 620 is sleeved and fixed on the outer side of the connecting shaft, and a cable 1 630 is wound and fixed on the outer side of the winding wheel 620, 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 a connecting rod 1 340 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 1 340, 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 at 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. A ring 631 is fixed to one end of the cable 1 630 that passes through the winding wheel 620. 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 that 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, closes the front contact, and connects the green light circuit of the signal machine, so that the track circuit lights 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 position, a measuring vehicle 100 is arranged at both ends of the rails of 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 instruction manual Figure 8, the cable 1 630 of the two measuring vehicles 100 short-circuits the longer rail, and there is a circuit break position in the rail at this distance, for example, the wavy line is the circuit break position, 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, and the reduction motor 2 610 fixed on the circular plate 511 rotates with the winding wheel 620 to reel in the excessively long cable 1 630 between the two measuring vehicles 100, and when the measuring vehicle 100 moves over the circuit break position, the rail is disconnected 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-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-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 track circuit lights up green, indicating that the short-circuit position has been found correctly.
