Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flatness monitoring, in particular to a contact net conductor flatness monitoring device. BACKGROUND

[0002] As the core power supply carrier of rail transit trains, the flatness of the contact net conductor directly determines the quality of the bow net contact. If the conductor has flatness defects such as bending, bulging, uneven wear, etc., it will cause poor contact between the pantograph and the conductor, causing arc burning and abnormal wear of the conductor, and even causing bow net failure, affecting the stability of train power supply and driving safety. Therefore, regular and accurate monitoring of the flatness of the contact net conductor is a key link to ensure the safety of rail transit operation. However, the existing flatness monitoring devices mostly rely on manual inspection or single sensor detection, and manual inspection is low in efficiency and strong in subjectivity, and single sensor is prone to defect omission due to limited detection angle; although some automatic devices can achieve continuous detection, they lack a review mechanism for conventional detection, the reliability of the detection results is insufficient, and they cannot simultaneously capture on-site images, making it difficult for maintenance personnel to intuitively grasp the defect situation; in addition, dust and debris are easily attached to the surface of the conductor, which will interfere with the detection accuracy of the sensor, and the existing devices need to be manually cleaned in advance, increasing the operation and maintenance cost and operation time.

[0019] Compared with the prior art, the present invention provides a device for monitoring the straightness of contact wires, which has the following advantages:

[0020] 1. This contact wire straightness monitoring device performs translational detection on the wire through a straightness monitoring mechanism. During conventional detection, the sliding wheel drives the shaft disk to move the piston assembly, allowing the ball to slide in the track groove and achieve the rotation of the track. This allows the detection component to perform comprehensive detection around the circumference of the wire. During the detection process, on the one hand, the accuracy of position detection is improved by fusion of multi-dimensional detection data, and on the other hand, the conventional detection results are reviewed with comprehensive detection results and image data.

[0021] 2. This contact wire straightness monitoring device uses a straightness monitoring mechanism to move and detect the wire, causing the sliding wheel at the other end to drive the piston assembly to move. The rotation of the rotating rail drives the cleaning strip to rotate, which cleans the surface of the wire. The movement of the piston assembly also allows for air venting through the cleaning assembly, thus achieving wire cleaning. The cleaned wire surface reduces the interference of impurities on the sensor detection signal, ensuring the reliability of the straightness detection data and reducing maintenance costs.

[0022] 3. This contact wire straightness monitoring device uses a straightness monitoring mechanism to perform routine moving inspection of the wire. During the movement, the sliding component is driven by a shaft disc linkage piston assembly. With the cooperation of the rail groove, the rotating rail drives the cleaning strip to rotate, which can pre-clean the wire. At the same time, the cleaning component can perform blowing and cleaning. The cleaned wire surface is free of impurities, allowing the detection component and monitoring head to obtain more accurate detection data and image information, avoiding missed defects caused by impurities. The rotating rail movement can also drive the detection component to perform comprehensive inspection of the wire. During the comprehensive inspection, when data changes occur, the image captured by the monitoring head can be recorded simultaneously. If it is found that the detection results are affected by incomplete cleaning in some areas, a re-inspection can be performed immediately. At the same time, no additional power module is required, simplifying the equipment structure and reducing energy consumption. Attached Figure Description

Therefore, they should not be construed as limitations on this invention.

[0038] Example 1: Refer to Figures 1-11 A device for monitoring the straightness of overhead contact line conductors includes a straightness monitoring mechanism 100, and an auxiliary mechanism 200 is provided on the straightness monitoring mechanism 100;

[0039] The straightness monitoring mechanism 100 includes a support plate 101, on which a monitoring device 102 is mounted. The monitoring device 102 enables routine testing of the conductor. Both ends of the support plate 101 are equipped with pulleys 104 and positioning components 103. The positioning component 103 includes a screw 1031, which is rotatably mounted on the support plate 101 via bearings. A handle 1032 is fixedly connected to the bottom end of the screw 1031, allowing easy rotation of the screw 1031. This allows the screw 1031 to interact with a threaded cylinder 1033, which in turn drives the upper pulley 103. 5. Move downwards to allow the upper pulley 1035 and lower pulley 104 to cooperate and position the device on the conductor, so that the monitoring device 102 can perform translational detection on the conductor. A threaded cylinder 1033 is threadedly connected to the screw 1031. A reinforcing plate 1034 is fixedly connected to the top of the threaded cylinder 1033. A telescopic rod 1036 and the upper pulley 1035 are fixedly connected to the bottom of the reinforcing plate 1034. The telescopic rod 1036 can ensure that the upper pulley 1035 moves smoothly up and down. The bottom end of the telescopic rod 1036 is fixedly connected to the support plate 101. Both rotating ends of the lower pulley 104 are fixedly connected to the shaft disk 105.

[0040] The auxiliary mechanism 200 includes two piston assemblies 205 and two guide assemblies 201. Each guide assembly 201 includes a guide shell 2011. Multiple sets of side guide wheels 2012 are arranged on both sides of the inner cavity of the guide shell 2011. A ring-shaped slide rail 2014 is slidably connected to each set of side guide wheels 2012. The ring-shaped slide rail 2014 is fixedly connected to the rotating rail 207. Each set of side guide wheels 2012 consists of two wheels. A limit wheel 2013 is arranged between the two side guide wheels 2012. The side guide wheels 2012 and the limit wheel 2013 support and limit the ring-shaped slide rail 2014. Simultaneously, the rolling motion of the limit wheel 2013 and the side guide wheels 2012 ensures the smooth movement of the ring-shaped slide rail 2014. Each piston assembly 205 includes a piston shell 2051. A single... The one-way valve 2056 ensures that the piston housing 2051 can be supplied with gas in one direction, facilitating gas replenishment. The piston housing 2051 is fixedly connected to the support plate 101. A sealing plug 2052 is provided in the piston housing 2051. Three connecting rods 2053 and two movable rods 2054 are fixedly connected to both sides of the sealing plug 2052. A slide rail frame 2055 is fixedly connected to one end of the movable rod 2054. Two piston assemblies 205 and guide assemblies 201 are respectively located at both ends of the support plate 101. The two slide rail frames 2055 of the piston assembly 205 are slidably connected to two shaft disks 105. The shaft disks 105 are driven to rotate by the lower pulley 104, so that the shaft end of the shaft disk 105 can slide in the slide rail frame 2055, and at the same time, it can drive the slide rail frame 2055 to achieve reciprocating motion.

[0041] Each of the three ends of the piston assembly 205 is provided with a sliding assembly 206. The sliding assembly 206 includes an adjusting rod 2061, which slides through one end of the connecting rod 2053. A ball bearing 2063 is provided at one end of the adjusting rod 2061 and is slidably connected to a groove 204. Each groove 204 is arranged at an angle, and the depth of each groove 204 gradually increases from one end to the other, allowing for a smooth transition between shallow and deep sections at the junctions. The angled arrangement of the grooves 204 maintains communication between them. Simultaneously, the ball bearing 2063 can control the rotation of the guide rail 207 via the inclined surface. The increasing depth of the groove 204 allows the ball bearing 2063 to move from the shallow end of one groove 204 to the deeper end of another, and a spring 2062 ensures that the ball bearing 2063 enters another groove 204. The three rollers 2063 are distributed at different circumferential positions, which prevents them from leaving the grooves 204 and affecting the circumferential movement of the rotating track 207. The other end of the adjusting rod 2061 is fixedly connected to a spring 2062, which holds the adjusting rod 2061 in place. The spring 2062 has elastic force to ensure that the rollers 2063 are well in the grooves 204. As the rollers 2063 slide from the deep part of the groove 204 to the shallow part, the spring 2062 can store elastic potential energy. When the rollers 2063 slide from the shallow part to the deep part of another groove 204, the elastic potential energy of the spring 2062 is released, ensuring that the rollers 2063 move smoothly along the deep part of the groove 204. One end of the spring 2062 is fixedly connected to the connecting rod 2053. The piston assembly 205 is also connected to the cleaning assembly 202.

[0042] Two guide components 201 are respectively equipped with a cleaning strip 208 and a detection component 203. The detection component 203 includes a monitoring head 2033, a supplementary light 2034, and a slide bar 2031. The supplementary light 2034 can provide supplementary lighting to ensure the clarity of the image uploaded by the monitoring head 2033. The monitoring head 2033 and the supplementary light 2034 are mounted on the rotating rail 207. The two ends of the slide bar 2031 are respectively equipped with a detection ball 2032 and a pressure sensor 2035. The pressure sensor 2035 can detect the pressure change of the detection ball 2032 and feed the data back to the terminal. The pressure sensor 2035 is fixedly connected to the rotating rail 207 by a bracket. A controller 2036 is installed below the pressure sensor 2035. The guide component 201 is equipped with a rotating rail 207. The rotating rail 207 has multiple rail grooves 204. The multiple rail grooves 204 are connected and arranged in a ring. One end of the sliding component 206 is located in the rail groove 204.

[0043] In this embodiment: the straightness monitoring mechanism 100 performs translational detection on the conductor. During conventional detection, the sliding wheel 104 drives the shaft disk 105 to drive the slide rail frame 2055 to reciprocate. The slide rail frame 2055 drives the movable rod 2054 to reciprocate. The movable rod 2054 drives the sealing plug 2052 to reciprocate. The sealing plug 2052 drives the connecting rod 2053 and the sliding component 206 to reciprocate, allowing the ball 2063 to slide in the rail groove 204 and realize the rotation of the rotating rail 207. The rotating rail 207 drives the detection component 203 to rotate, allowing the detection ball 2032 to perform comprehensive detection around the circumference of the conductor. During the detection process, on the one hand, the accuracy of position detection is improved by multi-dimensional detection data fusion, and on the other hand, the conventional detection results are reviewed with comprehensive detection results and image data. When a straightness defect is identified, maintenance personnel can intuitively confirm the defect shape and location through the corresponding image, avoiding misjudgment or omission.

The straightness monitoring mechanism 100 includes a support plate 101. Both ends of the support plate 101 are provided with a sliding wheel 104 and a positioning component 103. Both rotating ends of the sliding wheel 104 are fixedly connected to a shaft disk 105.

[0045] The auxiliary mechanism 200 includes two piston assemblies 205 and two guide assemblies 201. Each guide assembly 201 has a rotating rail 207. Each rotating rail 207 has a cleaning strip 208 and a detection component 203. Multiple rail grooves 204 are formed on each rotating rail 207. The two piston assemblies 205 and guide assemblies 201 are respectively located at both ends of the support plate 101. Two sliding rail frames 2055 of the piston assembly 205 are slidably connected to two shaft discs 105. Three ends of each piston assembly 205 are provided with… The piston assembly 205 is connected to the cleaning assembly 202, which includes a sliding component 206 and a cleaning head 2022. The cleaning assembly 202 includes a delivery pipe 2021 and a cleaning head 2022. Gas is delivered through the delivery pipe 2021 and discharged through the cleaning head 2022 to purge and clean the wire, reducing impurities. The two ends of the delivery pipe 2021 are connected to the piston housing 2051 and the cleaning head 2022, respectively. The cleaning head 2022 is mounted on the support plate 101, and the two cleaning heads 2022 are located on both sides of the wire.

[0046] In this embodiment: the straightness monitoring mechanism 100 moves and detects on the conductor, and the sliding wheel 104 at the other end drives the piston assembly 205 to move through the shaft disk 105, so that the sliding assembly 206 moves in the track groove 204 and drives the rotating rail 207 to rotate. The rotating rail 207 drives the cleaning strip 208 to rotate. The cleaning strip 208 can clean the surface of the conductor, and the movement of the piston assembly 205 can also exhaust air through the cleaning assembly 202, thereby realizing the blowing and cleaning of the conductor. The cleaned conductor surface can reduce the interference of impurities on the sensor detection signal, ensure the reliability of the straightness detection data, and reduce the operation and maintenance costs.

[0047] Example 3: Reference Figures 1-3 , Figure 5 and Figure 7 A straightness monitoring device for contact wires includes a straightness monitoring mechanism 100. The straightness monitoring mechanism 100 includes a support plate 101. A monitoring device 102 is provided on the support plate 101. Both ends of the support plate 101 are provided with a sliding wheel 104 and a positioning component 103. Both rotating ends of the sliding wheel 104 are fixedly connected to a shaft disk 105.

[0048] The auxiliary mechanism 200 includes two piston assemblies 205 and two guide assemblies 201. The two piston assemblies 205 and the guide assemblies 201 are respectively located at both ends of the support plate 101. The two slide rail frames 2055 of the piston assembly 205 are slidably connected to the two shaft disks 105 respectively. Each of the three ends of the piston assembly 205 is provided with a sliding component 206. The piston assembly 205 is also connected to the cleaning component 202. The guide component 201 is provided with a rotating rail 207. The two rotating rails 207 are respectively provided with a cleaning strip 208 and a detection component 203. Multiple rail grooves 204 are opened on the rotating rails 207. The multiple rail grooves 204 are connected to each other and arranged in a ring. One end of the sliding component 206 is located in the rail groove 204.

[0049] In this embodiment: the straightness monitoring mechanism 100 performs routine moving inspection of the conductor. During the movement, the piston assembly 205 driven by the shaft disk 105 drives the sliding assembly 206 to move. With the cooperation of the rail groove 204, the rotating rail 207 drives the cleaning strip 208 to rotate, which can pre-clean the conductor. At the same time, the cleaning assembly 202 can perform blowing and cleaning. The cleaned conductor surface eliminates impurities and interference, allowing the detection assembly 203 and the monitoring head 2033 to obtain more accurate detection data and image information, avoiding missed defects caused by impurities. The movement of the rotating rail 207 can also drive the detection assembly 203 to perform comprehensive detection of the conductor. During the comprehensive detection process, when data changes occur, the image captured by the monitoring head 2033 can be recorded simultaneously. If it is found that the detection results are affected by incomplete cleaning of certain areas, a re-inspection can be performed immediately. At the same time, there is no need to add an additional power module, which simplifies the equipment structure and reduces energy consumption.

[0050] Working principle: When inspecting the contact wire, the screw 1031 is rotated by turning the handle 1032. The screw 1031 drives the threaded cylinder 1033 to move downward, which causes the reinforcing plate 1034 to drive the upper pulley 1035 to move downward. The upper pulley 1035 and the lower pulley 104 are positioned on the wire. Then, the monitoring device 102 is moved on the wire to perform the inspection.

[0051] During the movement, the sliding wheel 104 also drives the shaft disk 105 to rotate, the shaft disk 105 drives the slide rail frame 2055 to reciprocate, the slide rail frame 2055 drives the movable rod 2054 to reciprocate, the movable rod 2054 drives the sealing plug 2052 to reciprocate, the sealing plug 2052 can take in air through the one-way valve 2056 and exhaust air through the delivery pipe 2021, so that the cleaning head 2022 can blow and clean the wire. The sealing plug 2052 also drives the connecting rod 2053 and the sliding component 206 to reciprocate, so that the ball 2063 slides in the rail groove 204 and slides in each rail groove 204 through the intersection of the depth of the rail groove 204, and drives the annular slide rail 2014 to rotate. The annular slide rail 204 drives the rotating rail 207 to rotate, and the rotating rail 207 drives the cleaning strip 208 to clean the wire.

[0052] Another rotating track 207 drives the detection component 203 to move, causing the detection ball 2032 to move circumferentially along the guide wire. When the pressure sensor 2035 detects a change in pressure data, it provides supplementary light through the supplementary light 2034, enabling the monitoring head 2033 to collect image data. The image data captured by the monitoring head 2033 can indicate whether there is a problem with impurity residue. If not, the data is recorded directly. If there is a problem with impurities, it can be further cleaned and re-inspected.
