Description

A railway catenary positioning angle measuring device Technical Field

[0001] This utility model relates to the field of angle measuring tools, and in particular to a railway catenary positioning angle measuring device. Background Technology

[0002] In railway electrification engineering, the overhead contact line is a special power transmission line erected along the railway line to supply power to electric locomotives; it is the main structure of the project. With the development of railway transportation, the requirements for its performance and installation accuracy are constantly increasing. The installation and maintenance of the overhead contact line are crucial to the normal operation of trains, especially at high speeds and in harsh weather conditions; accurate detection of performance indicators can prevent malfunctions. Against this backdrop, railway overhead contact line positioning angle measuring devices have emerged, used for construction surveying and positioning and subsequent boundary encroachment measurements, which are of great significance for improving installation quality and ensuring railway safety.

[0003] Patent document CN222761616U discloses a railway catenary positioning angle measuring device, which mainly consists of an electronic measuring instrument, a fixed body, a measuring plate, an adjusting knob, and a fixing mechanism. Its key technical feature is that the entire measuring device is fixed to the contact line via the fixing mechanism. The electronic measuring instrument is mounted on one side of the fixed body, and the measuring plate is rotatably connected to the other side via an adjusting knob. The adjusting knob passes through the electronic measuring instrument and is located on the side furthest from the fixed body.

[0004] However, existing technologies still have some shortcomings in practical applications. During the measurement process, the measuring plate needs to be rotated to be parallel with the locator. This operation mainly relies on the operator's observation. Due to limitations such as the operator's subjective judgment and skill level, it is difficult to ensure that the measuring plate and the locator are precisely parallel, which can easily lead to operational errors. Consequently, the measured angle will be inaccurate, affecting the accuracy and reliability of the measurement results.

[0005] Given the shortcomings of the existing technologies, it is of great practical significance to develop a railway catenary positioning angle measuring device that can effectively reduce operational errors and improve the accuracy of angle measurement. Summary of the Invention

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] Referring to Figures 1-3, this utility model provides a railway catenary positioning angle measuring device, which mainly consists of a telescopic component 1, a clamping component 4, an angle measuring component 2, a power supply, and a control unit.

[0043] The telescopic component 1 is equipped with an angle measuring component 2 at one end, which is connected to one end of the measuring plate 3 to measure the deflection angle of the measuring plate 3. The other end of the telescopic component 1 is connected to the clamping component 4, which is responsible for clamping the contact wire. The angle measuring component 2 and the power supply are electrically connected to the control unit, which is used to receive the deflection angle information.

[0044] Specifically, a plurality of touch components 5 are evenly installed on the measuring plate 3 along its length, with a preferred spacing of 50 mm between each touch component 5. The touch components 5 are used to determine the contact between the measuring plate 3 and the positioner, and are electrically connected to the control unit to transmit the contact signal to the control unit.

[0045] Referring to Figure 3, the touch assembly 5 includes a trigger switch 51, a movable rod 52, and a reset member 53. The trigger switch 51 is a micro-limit switch; the circuit is connected when touched, and disconnected otherwise. The trigger switch 51 is fixedly connected to a preset position within the measuring plate 3. Multiple trigger switches 51, the power supply, and the control unit are electrically connected to form an electrical series circuit. When multiple trigger switches 51 are touched simultaneously, the power supply supplies power to the control unit. The movable rod 52 is a cylindrical rod, one end of which is embedded within the measuring plate 3 and positioned opposite the trigger switch 51, while the other end extends outside the measuring plate 3. The movable rod 52 can move between a first position and a second position. In the first position, the movable rod 52 is embedded within the measuring plate 3, and one end triggers the trigger switch 51, activating the trigger switch 51. In the second position, the other end of the movable rod 52 protrudes from the measuring plate 3, and a certain gap is maintained between the protruding end of the movable rod 52 and the trigger switch 51, disengaging the trigger switch 51.

[0046] Specifically, the reset element 53 is a compression spring, located inside the measuring plate 3 at the position corresponding to the movable rod 52. One end of the spring is fixedly connected to the inner wall of the measuring plate 3, and the other end is fixedly connected to the end of the movable rod 52. It is used to drive the movable rod 52 from the first position to the second position. When the measuring plate 3 contacts the positioner, the positioner overcomes the force of the reset element 53 and pushes the movable rod 52 from the second position to the first position, thereby triggering the trigger switch 51 to energize the control unit and the angle measuring assembly 2.

[0047] Optionally, the measuring plate 3 is provided with stepped holes corresponding to the movable rod 52, with the smaller hole of the stepped hole located between the larger hole of the stepped hole and the trigger switch 51. The reset member 53 is a compression spring provided in the larger hole of the stepped hole, with one end of the compression spring connected to the end wall of the larger hole of the stepped hole and the other end connected to the end cap 54 at the other end of the movable rod 52.

[0048] The movable rod 52 is vertically fixedly connected to a first limiting rod 55, and the measuring plate 3 is provided with a first limiting groove 56. During the movement of the movable rod 52 in the first and second positions, the first limiting rod 55 and the first limiting groove 56 are slidably connected, thereby limiting the movement trajectory of the movable rod 52 and ensuring its stable movement. The movable rod 52 is perpendicular to the rotation axis of the measuring plate 3, so that when the measuring plate 3 deflects, the movable rod 52 can better contact the positioner, improving the accuracy of contact detection.

[0049] Referring again to Figures 1-2, the telescopic assembly 1 includes a fixed block 11 and a sliding block 13. One end of the fixed block 11 is fixedly connected to the clamping assembly 4, and a sliding protrusion 12 is provided on one side. The sliding block 13 is connected to the angle measuring assembly 2, and a sliding groove 14 is provided on it. The sliding groove 14 is adapted to the sliding protrusion 12, so that the sliding block 13 can slide along the sliding protrusion 12. A display screen 6 is installed on the sliding block 13, which houses a power supply and a control unit. The display screen 6 is an LCD screen, electrically connected to the control unit, used to display the measured deflection angle, allowing the operator to intuitively read the measurement results. The power supply uses a removable nickel-cadmium battery for easy replacement.

[0050] Optionally, a second limiting groove 15 is provided on the sliding block 13, and the second limiting groove 15 is provided along the sliding direction of the sliding block 13; a second limiting rod 16 is fixedly installed on the fixed block 11, and the second limiting rod 16 is slidably connected to the second limiting groove 15, thereby limiting the sliding trajectory of the sliding block 13 and ensuring that the telescopic assembly 1 can be stably telescopic.

[0051] The angle measuring component 2 uses an angle sensor, which is electrically connected to the control unit. Its input shaft is fixedly connected to one end of the measuring plate 3, which can detect the deflection angle of the measuring plate 3 in real time and transmit the angle information to the control unit for processing and display.

[0052] Referring to Figures 4-5, the clamping assembly 4 includes a fixed clamp 41, a movable clamp 42, a guide rod 43, and a threaded rod 44. One end of the fixed clamp 41 is fixedly connected to the end of the fixed block 11 away from the angle measuring assembly 2. The movable clamp 42 is disposed opposite to the fixed clamp 41 and is slidably connected to the fixed clamp 41. The guide rod 43 is fixedly mounted on the movable clamp 42. The guide rod 43 is disposed along the sliding direction of the movable clamp 42 and is slidably connected to the fixed clamp 41 to ensure smooth movement of the movable clamp 42. The threaded rod 44 is disposed parallel to the guide rod 43. One end of the threaded rod 44 is rotatably connected to the fixed clamp 41, and the other end is threadedly connected to the movable clamp 42. By rotating the threaded rod 44, the movable clamp 42 can be moved relative to the fixed clamp 41, thereby clamping or releasing the contact wire.

[0053] The working principle of this utility model is as follows:

[0054] First, by rotating the threaded rod 44, the fixed clamp 41 and the movable clamp 42 are moved away from each other. Then, the fixed clamp 41 and the movable clamp 42 are placed on both sides of the contact line. The threaded rod 44 is rotated in the opposite direction to bring the fixed clamp 41 and the movable clamp 42 closer to each other, thereby clamping the contact line.

[0055] Then, slide the sliding block 13 and rotate the measuring plate 3 so that the end of the measuring plate 3 with the end cap 54 is in contact with the positioner. At this time, the movable rod 52 contacts the trigger switch 51, and the control unit, angle sensor and display screen 6 are powered on. After the control unit is powered on, it reads the deflection angle measured by the angle sensor and compares it with the initial angle stored internally. Then, it feeds back the difference between the deflection angle and the initial angle to the display screen 6 for display, so that the deflection angle of the contact wire or clamp can be obtained.

[0056] Finally, after the measurement is completed, the fixed clamp 41 and the movable clamp 42 are moved away from each other by rotating the threaded rod 44, thereby releasing the clamp on the contact wire.

[0057] It should be noted that the control unit preferably uses a PLC device, which has a built-in storage unit that can store the initial angle of the measuring plate 3. This angle can be memorized when power is off and retrieved when power is on again. The initial angle is the angle when the measuring plate 3 is parallel to the sliding block 13 and the other end of the measuring plate 3 is adjacent to the clamping assembly 4.

[0058] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0059] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
