Description

Technical Field

[0001] This invention pertains to contact wire testing devices, and specifically relates to a contact wire testing device for railway power supply and its usage method. Background Technology

[0002] Railway and urban rail transit renovation and expansion projects often involve repeated dismantling and alteration of the overhead contact system. The railway overhead contact system is the continuous "refueling station" for trains in the railway operation system; its dense network and age directly affect the normal high-speed operation of trains. Renovation and expansion projects require utilizing railway vertical power outage windows for surface inspection of the power supply contact lines. During these windows, a large number of trains along the line must wait at adjacent stations for construction to be completed before they can pass. This results in limited approved construction time, a large workload, and the need to complete the work within the stipulated time and to the required standards to ensure smooth train operation.

[0003] Contact wire surface inspection is a key technology that detects the wear, abrasion, and surface condition of the contact wire (especially the contact surface between the contact wire and the pantograph), such as whether deflection has occurred. It aims to ensure that the contact wire can supply power smoothly. If deflection occurs, the contact surface between the contact wire and the train will be reduced, affecting the power supply effect.

[0004] Traditional railway overhead contact line renovation and expansion construction utilizes precious "maintenance windows" to organize a large number of workers in multiple groups to erect the contact wires. This involves manually and visually inspecting the entire contact wire from start to finish to ensure it is aligned. However, given the short construction windows and the close coordination between each step in railway renovation and expansion projects, manual inspection is prone to errors, leading to the need to restart the contact wire alignment process and disrupting the normal operation of trains along the line. To address these problems, this invention provides a railway power supply contact wire alignment device. Summary of the Invention

[0005] To address the aforementioned technical problems, the technical solution adopted by this invention is: a contact wire contact surface testing device for railway power supply. The device includes a U-shaped frame with two symmetrically arranged rollers. The rollers are rotatably engaged with connecting columns on the U-shaped frame. An adjustment mechanism is connected to the U-shaped frame to adjust its height. The U-shaped frame also includes a lighting mechanism and a display mechanism. There are two lighting mechanisms, each including a lamp, which is fixedly mounted on the U-shaped frame. When the contact wire is being tested, the rollers move along the contact wire, and the display mechanism displays the test results.

[0006] Preferably, the lighting mechanism further includes a reflector, which is rotatably mounted on a U-shaped frame. One end of a rotating rod is rotatably mounted on the reflector, and the other end of the rotating rod is rotatably mounted on a sliding block. The sliding block is fixedly connected to a pull rod. When it is necessary to adjust the angle of the reflector relative to the lamp, the pull rod drives the sliding block to move, thereby adjusting the angle between the rotating rod and the reflector.

[0007] Preferably, the lighting mechanism further includes an anti-slip pad, which is fitted onto the outer ring of the pull rod. The pull rod is slidably engaged with the U-shaped frame, and the sliding block is slidably engaged with the rectangular groove on the U-shaped frame.

[0008] Preferably, the display mechanism includes a level, which is fixedly mounted on a U-shaped frame.

[0009] Preferably, the display mechanism includes a placement slot, which is mounted on a U-shaped frame. An indicator ball is slidably installed inside the placement slot, and counters are provided at both ends inside the placement slot.

[0010] Preferably, the adjusting mechanism includes a support plate, which is fixedly connected to a lifting rod. The lifting rod is provided with a plurality of positioning holes arranged linearly, and the positioning holes are detachably connected to positioning pins.

[0011] Preferably, the adjustment mechanism further includes two symmetrically arranged support arms, one end of which is rotatably connected to the U-shaped frame, and the other ends of the two support arms are respectively rotatably mounted on the adjustment assembly. The angle of the support arms is adjusted by the adjustment assembly to adjust the height of the U-shaped frame.

[0012] Preferably, the adjustment assembly includes two sliders with opposite thread directions, each slider being rotatably connected to two support arms. The sliders are threadedly engaged with threaded rods, which are rotatably mounted on slide rails, with one end of the threaded rods fixedly connected to a handwheel. The sliders are slidably engaged with the slide rails, and the slide rails are slidably engaged with the lifting rod.

[0013] Preferably, the adjustment mechanism further includes a support rod, which is fixedly connected to the slide rail, and the outer ring of the support rod is fitted with an anti-slip pad.

[0014] On the other hand, the present invention also provides a method for using a railway power supply contact wire contact surface device, comprising the following steps:

[0015] S1: By turning the handwheel, the threaded rod slides on the slide rail, thereby moving the slider on the slide rail, and the height of the U-shaped frame is adjusted by the support arm.

[0016] S2: Push the lifting rod to slide on the slide rail to adjust the height of the pallet relative to the contact line, so that the pallet contacts the ground of the contact line, and insert the positioning pin into the positioning hole to complete the positioning of the lifting rod.

[0017] S3: By dragging the anti-slip pad two, the rollers on the U-shaped frame slide along the grooves on both sides of the contact line to perform surface testing on the contact line, and the test results are displayed through the display mechanism.

[0018] The beneficial effects of this invention compared with the prior art are: (1) This invention uses an adjustment mechanism, an illumination mechanism and a display mechanism, in conjunction with rollers to complete the surface inspection of the contact line, and utilizes the mechanized inspection method of the rollers sliding along the contact line groove, which significantly improves the inspection speed and visualizes the inspection results, thus improving the accuracy of the inspection results; (2) Through display mechanisms such as a level, an indicator ball and a counter, the wear and deflection of the contact line are transformed into intuitive physical signals or quantitative data, eliminating the subjectivity and error of manual visual judgment and providing a reliable basis for subsequent maintenance; (3) The adjustment mechanism can flexibly adjust the height of the U-shaped frame to adapt to the contact line inspection needs of different positions; the adjustable reflector and dual-lamp design of the illumination mechanism enhance the lighting effect in the dim tunnel environment; the setting of anti-slip pad one and anti-slip pad two makes the operation more convenient and comfortable.

[0028] To facilitate understanding of the present invention, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments.

Thus, unless otherwise stated, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; "multiple" means two or more.

[0029] Example: Figures 1-8 The diagram shows a contact wire contact surface testing device for railway power supply. The device includes a U-shaped frame 1 with two symmetrically arranged rollers 3 on it. The rollers 3 are rotatably engaged with the connecting column 2 on the U-shaped frame 1. An adjustment mechanism is connected to the U-shaped frame 1 to adjust its height. The U-shaped frame 1 is also equipped with a lighting mechanism and a display mechanism. There are two lighting mechanisms, each including a lamp 5, which is fixedly installed on the U-shaped frame 1. When the contact wire 25 is being tested, the rollers 3 move along the contact wire 25. The display mechanism is used to display the test results.

[0030] like Figure 1 , Figure 7As shown, when performing surface inspection on the contact wire 25, the height of the U-shaped frame 1 is adjusted by the adjustment mechanism so that the rollers 3 on both sides of the U-shaped frame 1 are positioned on the wire grooves 26 on both sides of the contact wire 25. The contact wire 25 is inspected by moving the rollers 3 along the wire grooves 26. Initially, the two rollers 3 are horizontal and can move along the wire grooves 26. Because the rollers 3 are rotatably engaged with the connecting post 2, the rollers 3 rotate as they move along the wire grooves 26, reducing the difficulty of movement.

[0031] When the contact line 25 deflects, it will cause the two rollers 3 to no longer be horizontal, inevitably resulting in one roller 3 being higher than the other roller 3. That is, the U-shaped frame 1 deflects. At this time, the display mechanism will intuitively show the deflection and the direction of the deflection.

[0032] After a deflection occurs, the dim lighting inside the tunnel makes it difficult for workers to observe. The position of the roller 3 at this point can be illuminated by the lamp 5 in the lighting mechanism, making it easier for workers to mark the spot and for subsequent maintenance. Simultaneously, the lighting device also allows workers to easily observe the results displayed by the display mechanism.

[0033] In this embodiment, when the roller 3 is along the grooves 26 on both sides of the contact line 25, the operator can move the adjustment structure to make the adjustment mechanism drive the U-shaped frame 1 to move, so that the roller 3 installed on both sides of the U-shaped frame 1 can move.

[0034] The lighting mechanism also includes a reflector 6, which is rotatably mounted on a U-shaped frame 1. One end of a rotating rod 7 is rotatably mounted on the reflector 6, and the other end of the rotating rod 7 is rotatably mounted on a sliding block 8. The sliding block 8 is fixedly connected to a pull rod 9. When it is necessary to adjust the angle of the reflector 6 relative to the lamp 5, the sliding block 8 is moved by the pull rod 9 to adjust the angle between the rotating rod 7 and the reflector 6.

[0035] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, in this embodiment, when the lamp 5 illuminates the area where the contact line 25 deflects, the angle of the reflector 6 can be adjusted. That is, the lever 9 can be pushed towards the side closer to the lamp 5 or pulled away from the lamp 5, causing the lever 9 to move the sliding block 8. This causes the sliding block 8 to push the rotating rod 7, which in turn causes the reflector 6 to rotate clockwise or counterclockwise, thus adjusting the angle of the lever 9 relative to the lamp 5. The light emitted by the lamp 5 will shine on the surface of the reflector 6 and be reflected by the reflector 6, concentrating the light on the current position of the roller 3.

[0036] The lighting mechanism also includes an anti-slip pad 10, which is fitted around the outer ring of the pull rod 9. The pull rod 9 slides with the U-shaped frame 1, and the sliding block 8 slides with the rectangular groove 4 on the U-shaped frame 1.

[0037] like Figure 1 , Figure 2 As shown in the preferred embodiment, the outer ring of the pull rod 9 is fitted with an anti-slip pad 10. Multiple spherical protrusions are provided on the anti-slip pad 10. When the operator grips the anti-slip pad 10, the protrusions increase the friction between the operator's hand and the pad, effectively preventing slippage when the operator grips the pull rod 9 directly. Furthermore, the sliding block 8 slides in conjunction with the rectangular groove 4 on the U-shaped frame 1, and the rectangular groove 4 guides the sliding block 8.

[0038] It is understood that this implementation includes two symmetrically arranged lighting devices, so that when either side of the contact line 25 deflects, the operator can adjust either of the two reflectors 6 accordingly.

[0039] The display mechanism includes a level 22, which is fixedly mounted on the U-shaped frame 1.

[0040] like Figure 5 As shown, the display mechanism is a level 22 fixedly installed on the U-shaped frame 1. When the roller 3 deflects, the U-shaped frame 1 will also deflect. At this time, the level 22 no longer maintains a horizontal position and can intuitively display the direction of deflection.

[0041] It is known that when the worker moves the U-shaped frame 1 through the adjustment mechanism, if the contact wire 25 deflects, the deflected contact wire 25 will inevitably give the U-shaped frame 1 a torsional force in a certain direction. This force will also be transmitted to the adjustment mechanism. The worker can clearly feel the torsional force.

[0042] The display mechanism includes a placement slot 23, which is mounted on a U-shaped frame 1. An indicator ball 24 is slidably installed inside the placement slot 23, and counters are provided at both ends inside the placement slot 23.

[0043] Alternatively, in another embodiment, the display mechanism includes a placement slot 23 and an indicator ball 24, such as Figure 3As shown, when the U-shaped frame 1 deflects, the indicator ball 24 is no longer in the middle position of the placement slot 23, but deflects and moves to one end of the placement slot 23. On the one hand, the movement of the indicator ball 24 can be visually observed, indicating that the contact line 25 has deflected and is no longer horizontal. On the other hand, when the indicator ball 24 moves to one end of the placement slot 23, it will touch the counter once, and the counter will generate one count. After the test is completed, the counter can be used to obtain the total number of deflections during this test, which facilitates the statistical analysis of the frequency of contact line 25 deflection in this area, and allows for targeted repairs and maintenance.

[0044] The adjustment mechanism includes a support plate 11, which is fixedly connected to a lifting rod 12. The lifting rod 12 is provided with a plurality of positioning holes 13 arranged in a linear manner, and the positioning holes 13 are detachably connected to positioning pins 14.

[0045] like Figure 2 , Figure 7 , Figure 8 As shown, in this embodiment, when the two placement slots 23 are respectively located at the positions of the two wire slots 26, the support plate 11 is positioned below the contact wire 25. The support plate 11 serves to support the contact wire 25, and of course, the detection results are not affected by the support plate 11. After adjusting the height of the U-shaped frame 1 and the roller 3 to move the roller 3 to the position of the wire slot 26, the height of the lifting rod 12 and the support plate 11 are adjusted. After completing the height adjustment of the support plate 11, the positioning pin 14 is inserted into the positioning hole 13 to lock the height of the lifting rod 12 and the support plate 11.

[0046] The adjustment mechanism also includes two symmetrically arranged support arms 15. One end of the support arm 15 is rotatably connected to the U-shaped frame 1, and the other ends of the two support arms 15 are respectively rotatably mounted on the adjustment assembly. The angle of the support arm 15 is adjusted by adjusting the adjustment assembly to adjust the height of the U-shaped frame 1.

[0047] like Figure 1 , Figure 2 As shown, the U-shaped frame 1 is connected to two support arms 15 in the adjustment mechanism. The height of the U-shaped frame 1 can be adjusted by adjusting the angle of the support arms 15 relative to the U-shaped frame 1.

[0048] The adjustment assembly includes two sliders 16 with opposite thread directions. The two sliders 16 are rotatably connected to two support arms 15 respectively. The sliders 16 are threadedly engaged with threaded rods 17. The threaded rods 17 are rotatably mounted on slide rails 19, and one end of the threaded rods 17 is fixedly connected to handwheels 18. The sliders 16 are slidably engaged with slide rails 19, and slide rails 19 are slidably engaged with lifting rods 12.

[0049] like Figure 1 , Figure 2 , Figure 6 , Figure 8 As shown, when adjusting the angle of the support arm 15 relative to the U-shaped frame 1, turn the handwheel 18 so that the handwheel 18 drives the threaded rod 17 to rotate on the slide rail 19. At this time, the two sliders 16 with opposite thread directions will slide along the slide rail 19 in a direction that is closer to or further away from each other. The angle of the support arm 15 connected to the slider 16 relative to the U-shaped frame 1 will change, thereby driving the U-shaped frame 1 to rise or fall, thus completing the height adjustment of the U-shaped frame 1.

[0050] In this embodiment, the lifting rod 12 is slidably engaged with the slide rail 19. After the height adjustment of the support plate 11 and the lifting rod 12 is completed, the positioning pin 14 is inserted into the corresponding positioning hole 13, and the position of the lifting rod 12 relative to the slide rail 19 no longer changes.

[0051] The adjustment mechanism also includes a support rod 20, which is fixedly connected to the slide rail 19, and the outer ring of the support rod 20 is fitted with an anti-slip pad 21.

[0052] like Figure 7 As shown, in this embodiment, a support rod 20 is fixedly installed below the slide rail 19, and an anti-slip pad 21 is provided on the outer ring of the support rod 20. The operator can hold the anti-slip pad 21 to move the U-shaped frame 1 and the roller 3 relative to the contact line 25. The function of the anti-slip pad 21 is to prevent slipping.

[0053] On the other hand, this embodiment also provides a method for forming the contact wire of a railway power supply contact wire, including the following steps:

[0054] S1: By turning the handwheel 18, the threaded rod 17 slides on the slide rail 19, thereby moving the slider 16 on the slide rail 19, and adjusting the height of the U-shaped frame 1 by the support arm 15.

[0055] S2: Push the lifting rod 12 to slide on the slide rail 19 to adjust the height of the support plate 11 relative to the contact line 25, so that the support plate 11 contacts the ground of the contact line 25, and insert the positioning pin 14 into the positioning hole 13 to complete the positioning of the lifting rod 12.

[0056] S3: By dragging the anti-slip pad 21, the rollers 3 on the U-shaped frame 1 slide along the grooves 26 on both sides of the contact line 25 to perform surface testing on the contact line 25, and the test results are displayed through the display mechanism.

[0057] Through the above steps, efficient and accurate surface inspection of the railway power supply contact wire 25 can be achieved. In step S1, rotating the handwheel 18 drives the threaded rod 17 to rotate, causing the slider 16 to move along the slide rail 19, thereby adjusting the angle of the support arm 15 and the height of the U-shaped frame 1. This ensures that the roller 3 is positioned appropriately corresponding to the groove 26 of the contact wire 25, guaranteeing stable contact between the device and the contact wire 25. In step S2, pushing the lifting rod 12 to slide on the slide rail 19 adjusts the height of the support plate 11 relative to the contact wire 25, allowing the support plate 11 to support the bottom of the contact wire 25. The lifting rod 12 is then positioned and fixed by inserting the positioning pin 14 into the positioning hole 13, preventing the device from shaking during the inspection process. In step S3, dragging the anti-slip pad 21 on the outer ring of the support rod 20 causes the roller 3 on the U-shaped frame 1 to slide smoothly along the grooves 26 on both sides of the contact wire 25. Combined with the level 22, placement slot 23, and indicator ball in the display mechanism, the inspection results are fed back in real time, facilitating observation and recording by the staff. The overall operation process is simple and quick, which can effectively reduce manual inspection errors and improve the accuracy and efficiency of contact wire 25 surface inspection.

[0058] In summary, this invention discloses a contact wire inspection device for railway power supply and its usage method. The device mainly includes a U-shaped frame 1, rollers 3, an adjustment mechanism, a lighting mechanism, and a display mechanism. The height of the U-shaped frame 1 is adjusted by the adjustment mechanism, allowing the rollers 3 to move smoothly along the grooves 26 on both sides of the contact wire 25. Sufficient illumination is provided by the lighting mechanism, and the display mechanism provides real-time feedback on whether the contact wire 25 exhibits deflection, wear, or other abnormal conditions, achieving efficient and accurate contact wire inspection. This technical solution has the advantages of reasonable structure, simple operation, and intuitive and accurate inspection results, significantly improving the work efficiency and accuracy of contact wire inspection, reducing reliance on manual labor, and avoiding missed inspections or misjudgments due to human error. Compared with traditional manual visual inspection methods, this invention better adapts to the actual needs of tight construction schedules and dense process connections in railway and urban rail transit reconstruction and expansion projects. Especially under vertical power outage window operation conditions, it provides strong technical support for ensuring the safe and stable operation of the railway power supply system, and has significant engineering application value and industry promotion significance.
