Description

Technical Field

[0001] This utility model relates to the technical field of railway overhead contact line construction, and more specifically, to an intelligent level for a rigid overhead contact line segment insulator in railway transportation. Background Technology

[0002] In daily construction, the rigid contact wire segment insulators in subway tunnel sections are mainly adjusted using a spirit level. However, the adjustment requirements are high, as multiple points on the segment insulator body and guide plate must be level simultaneously. This process not only relies heavily on the skills and experience of the operators, but is also limited by the functionality of existing spirit levels, making it impossible to achieve continuous and comprehensive adjustment of the entire guide plate. This results in difficulty in controlling adjustment accuracy and low work efficiency.

[0003] Specifically, the current method is prone to causing the insulator to exhibit a "high at the front and low at the back" phenomenon. At the same time, because it does not fully consider actual track conditions such as rail surface superelevation, it further reduces the accuracy and reliability of the calibration, making it difficult to meet the high-standard inspection and calibration requirements. Utility Model Content

[0004] This utility model provides an intelligent level for the rigid contact wire segment insulator of rail transit, which aims to solve the problems of low accuracy, slow efficiency and manual dependence of traditional level rulers. It provides a simple level measuring device to realize the synchronous detection and precise adjustment of the overall level of the guide plate.

[0005] To achieve the above objectives, this utility model provides an intelligent level for rigid contact wire segment insulators in rail transit, including a clamp and a leveling adjustment module;

[0006] The clamp includes a first gripper unit and a second gripper unit. The first gripper unit and the second gripper unit are symmetrically arranged on both sides of the busbar. A connecting shaft is provided between the first gripper unit and the second gripper unit. A first knob and a second knob are respectively provided on both sides of the connecting shaft.

The worm is connected to the first plate or the third plate through the pin unit. The first plate is fixedly connected to the rotating shaft of the turbine, and the second plate is also fixedly connected to the rotating shaft of the turbine. When the worm is rotated, the worm drives the turbine to rotate, thereby driving the first plate or the third plate to rotate around the rotating axis of the turbine.

[0008] Both the first and third flat plates are equipped with a three-dimensional tilt detection module, which collects the horizontal angle of the first and third flat plates in real time.

[0009] In one embodiment, the first gripper unit and the second gripper unit are provided with slots, the shape of which corresponds to the outer contour of the busbar, so that the two sides of the busbar are clamped in the slots.

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. The described embodiments are some embodiments of this application, but not all embodiments. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0036] Figure 1 This is a schematic diagram of the structure of an intelligent level for a rigid contact wire segment insulator in rail transit according to an embodiment of the present invention. The intelligent level for a rigid contact wire segment insulator in rail transit includes a clamp 100 and a leveling adjustment module.

[0037] like Figure 3 As shown, the clamp 100 includes a first gripper unit 110 and a second gripper unit 120, the first gripper unit 110 and the second gripper unit 120 as follows: Figure 8As shown, the first gripper unit 110 and the second gripper unit 120 are symmetrically arranged on both sides of the busbar. A connecting shaft 150 is provided between the first gripper unit 110 and the second gripper unit 120. A first knob 130 and a second knob 140 are respectively provided on both sides of the connecting shaft 150. The first knob 130 and the second knob 140 are axially connected to the first gripper unit 110 and the second gripper unit 120 through threads.

[0038] The horizontal adjustment module includes a first plate 270, a second plate 280, and a third plate 290. The first plate 270 and the third plate 290 are respectively connected to both ends of the second plate 280. Both the first plate 270 and the third plate 290 are equipped with worm gear mechanisms. Each worm gear mechanism includes a worm 210, a turbine meshing with the worm 210, a bearing seat 250 for fixing the worm 210, and a pin unit 260. The worm 210 is connected to the bearing seat 250 through the pin unit 260. The bearing seat is fixed to the first plate 270 or the third plate 290. The first plate 270 is fixedly connected to the rotating shaft of the turbine, and the second plate 280 is also fixedly connected to the rotating shaft of the turbine. When the worm 210 is rotated, the worm 210 drives the turbine to rotate, thereby driving the first plate 270 or the third plate 290 to rotate around the rotating axis of the turbine.

[0039] Both the first plate 270 and the third plate 290 are equipped with a three-dimensional tilt angle detection module 300, which collects the horizontal angle of the first plate 270 and the third plate 290 in real time.

[0040] Specifically, the components of the intelligent level of the rigid contact wire segment insulator in rail transit are symmetrically distributed along the third plate.

[0041] Furthermore, such as Figure 4 , Figure 11 As shown, the first turbine is connected to the first plate, and the first turbine is connected to the first plate 270 by a shaft, so that the rotation shaft of the first turbine and the first plate 270 are always on the same horizontal plane. The second turbine is connected to the third plate, and the second turbine is also connected to the third plate 290 by a shaft, so that the rotation shaft of the second turbine and the third plate 290 are always on the same horizontal plane. The first plate 270 and the third plate 290 drive the second plate 280 to rotate together with the turbine.

[0042] like Figure 3 As shown, two pin units 260 are fixed on two bearing seats 250 respectively, and the two ends of the worm 210 extend out of the pin units 260. The worm 210 is perpendicular to the straight line where the rotation axis of the turbine is located.

[0043] Rotating the worm gear 210 causes the meshing turbine to rotate, which in turn drives the first plate 270 and the third plate 290 connected by the shaft to perform pitching motion, thereby precisely adjusting the angle of the second plate 280 connected to the first and third plates 290 relative to the horizontal plane.

[0044] Specifically, the materials of the first plate 270, the second plate 280 and the third plate 290 are a combination of honeycomb composite material and engineering plastic. The first plate 270, the second plate 280 and the third plate 290 adopt the form of plate as the main structure of the level, and the clamps 100 on both sides are connected to the main structure through hinges.

[0045] In one embodiment, such as Figure 2 As shown, the first gripper unit 110 and the second gripper unit 120 are provided with slots, the shape of which corresponds to the outer contour of the busbar, so that the two sides of the busbar are clamped in the slots.

[0046] Specifically, the card slot can be designed in a V-shape or an arc shape to enhance clamping stability and centering accuracy.

[0047] In one embodiment, the first gripper unit 110 includes a positive threaded hole, the second gripper unit 120 includes a negative threaded hole, and the connecting shaft 150 passes through the positive threaded hole and the negative threaded hole.

[0048] One side of the connecting shaft 150 is provided with a positive thread and the other side is provided with a negative thread. The first knob 130 and the second knob 140 are respectively fixed at both ends of the connecting shaft 150.

[0049] Specifically, the first knob 130 and the second knob 140 are provided with anti-slip textures or handles to facilitate manual operation.

[0050] In one embodiment, the positive threaded hole of the first gripper unit 110 is screwed into the positive threaded end of the connecting shaft 150, and the negative threaded hole of the second gripper unit 120 is screwed into the negative threaded end of the connecting shaft 150.

[0051] Specifically, when the connecting shaft 150 rotates, the first gripper unit 110 and the second gripper unit 120 move synchronously towards or in opposite directions through the engagement of the positive and negative threads.

[0052] Furthermore, when rotating the connecting shaft 150, the first gripper unit 110 and the second gripper unit 120 can move inward or outward simultaneously to achieve rapid clamping and release of the busbar.

[0053] In one embodiment, pin units 260 extend from both ends of the worm gear 210 and are respectively fixedly mounted with a third knob 230 and a fourth knob 240, which are coaxially fixedly connected to the worm gear 210.

[0054] In one embodiment, the first plate 270, the second plate 280, and the third plate 290 are configured as honeycomb-shaped grooves, and the first plate 270, the second plate 280, and the third plate 290 are provided with holes. The first plate 270 and the third plate 290 are both connected to the second plate 280 through a drive shaft and rivets.

[0055] In one embodiment, such as Figure 10 , Figure 11 As shown, honeycomb-shaped grooves and holes are provided on the side that is not attached to the first plate 270, the second plate 280 and the third plate 290, and honeycomb-shaped grooves and holes are also provided on the side that is attached to the first plate 270, the second plate 280 and the third plate 290, in order to achieve portability.

[0056] In one embodiment, such as Figure 1 , Figure 4 As shown, honeycomb-shaped grooves and holes are provided on the side that is not attached to the first plate 270, the second plate 280 and the third plate 290, while the side that is attached to the first plate 270, the second plate 280 and the third plate 290 is solid, in order to satisfy both portability and high strength.

[0057] Specifically, such as Figure 9 As shown, a handle is provided on the second plate 280, and the handle is located on the side away from the busbar.

[0058] In one embodiment, the intelligent level of the rigid contact wire segment insulator for rail transit further includes a human-machine interaction module 400, which is hinged to the three-dimensional tilt angle detection module 300.

[0059] Specifically, the human-computer interaction module 400 is connected to the three-dimensional tilt detection module 300 through a hinge or folding mechanism, so that the angle and position of the human-computer interaction module 400 can be adjusted for easy observation and operation.

[0060] In one embodiment, such as Figure 5 As shown, the three-dimensional tilt detection module 300 and the human-computer interaction module are embedded inside the first plate 270 and the third plate 290.

[0061] Specifically, the three-dimensional tilt detection module 300 and the human-computer interaction module are installed in the cavity formed inside the first plate 270 and the third plate 290, which can reduce external interference and improve the compactness and protection level of the overall structure.

[0062] In one embodiment, such as Figure 6 As shown, the three-dimensional tilt detection module 300 includes a high-precision three-dimensional tilt sensor unit 310, a tilt detection main control unit 320, a built-in battery 340, a power switch 350, and a mounting housing 330. The high-precision three-dimensional tilt sensor unit 310 collects the current pitch angle and roll angle data in real time and transmits the current pitch angle and roll angle data to the tilt detection main control unit 320. The tilt detection main control unit 320 filters and calculates the received data and outputs the current levelness information and attitude deviation.

[0063] In one embodiment, such as Figure 7 As shown, the human-computer interaction module 400 includes a foldable touch-screen human-computer interaction control screen. The human-computer interaction module 400 receives the levelness information and attitude deviation from the tilt angle detection main control unit 320, and displays the levelness information and attitude deviation on the foldable touch-screen human-computer interaction control screen. The human-computer interaction module 400 is equipped with an error value accuracy range and an alarm unit.

[0064] Specifically, the high-precision three-dimensional tilt sensor unit 310 and the tilt detection main control unit 320 are placed inside the mounting housing 330, which is connected to the first plate 270.

[0065] Specifically, the human-machine interface module 400 also provides functions such as parameter setting, data logging, and prompts. The human-machine interface module 400 has a built-in intelligent monitoring system, including configurable error accuracy management: users can set the error value accuracy range, and when the levelness information exceeds the error value accuracy range, the information is transmitted to the alarm unit.

[0066] In one embodiment, the alarm unit can use acoustic alarms, with an integrated buzzer emitting warning sounds of different frequencies and rhythms. When the alarm unit receives information, it can emit an alarm sound, ensuring effective information delivery even in noisy environments or when the operator's eyes are not focused on the screen.

[0067] Furthermore, the human-machine interaction module 400 can automatically record the time, deviation value, and duration of each out-of-limit event, generating log files that can be queried and exported, providing data support for subsequent problem tracing, equipment status diagnosis, and process optimization.

[0068] Through the above design, the human-computer interaction module 400 not only realizes the display of basic information, but also upgrades into a comprehensive solution that integrates real-time monitoring, intelligent early warning, precise control and data management, significantly improving the accuracy, efficiency and security of operation.

[0069] This utility model has the following beneficial effects:

[0070] 1. Simple structure: The first, second, and third plates are made of sheet metal as the main structure of the level. The clamps on both sides are connected to the main structure through hinges, which satisfies the requirements of foldability and rigidity.

[0071] 2. High efficiency: The clamping and angle deflection of the fixture both adopt a threaded structure, which can be adjusted by simply rotating the knob, making operation convenient.

[0072] 3. High precision: By combining the worm gear mechanism and the three-dimensional tilt angle detection module, the horizontal angle can be adjusted and detected in real time, which improves the precision of horizontal adjustment.
