Description

Technical Field

[0001] This utility model relates to the field of contact wire positioning technology, and in particular to a flexible contact wire positioning triggering device. Background Technology

[0002] With the continuous expansion of industrial production scale and the improvement of intelligence, the requirements for equipment inspection are becoming increasingly stringent. In large factories, warehouses, power facilities, and other locations, traditional manual inspection methods suffer from low efficiency, high labor intensity, and a tendency to miss inspections. Inspection robots have emerged to address this need, as they can automatically inspect equipment according to preset routes and tasks. The pressure wheel device is a crucial component of the inspection robot's walking mechanism, and its performance directly affects the stability of the robot's movement.

[0003] Some existing overhead contact line positioning devices have relatively simple structures, and the connections between components are not flexible or robust enough. For example, the connection between the positioning tube and the insulator in some devices may only use a single fixing method, which is prone to loosening or damage after long-term use or under external impact, leading to a decrease in positioning accuracy and affecting the normal operation of the overhead contact line. Moreover, existing devices have poor adaptability to different installation environments and operating conditions, making effective adjustments and optimization difficult. Many existing overhead contact line positioning devices lack intelligent monitoring and control functions, requiring personnel to conduct regular on-site inspections and maintenance to understand the device's operating status and related parameters. This method is not only inefficient but also makes it difficult to monitor the device's operation in real time. If a fault occurs, it may not be detected and dealt with in a timely manner, potentially leading to the shutdown of the rail transit system and disrupting normal transportation order. Therefore, those skilled in the art have provided a flexible overhead contact line positioning triggering device to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0020] 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.

[0021] Reference Figure 1 — Figure 4 A flexible contact wire positioning triggering device includes a bracket 1, made of high-strength metal, possessing sufficient mechanical strength. It serves as the foundational load-bearing component of the entire device, providing stable installation support for other parts. Four anchor bolt holes are evenly distributed at the four corners of the bracket 1's bottom, allowing it to be securely fixed to the ground or other foundation structure, ensuring the overall stability of the device during operation. An upper insulator 2, made of high-insulation ceramic or composite material, is installed on the upper part of the bracket 1. It serves two purposes: firstly, providing electrical insulation to prevent current leakage to non-conductive components such as the bracket 1, ensuring system safety; and secondly, providing partial mechanical support to assist in fixing connected components.

[0022] The positioning tube 3 is typically a metal tube, with one end connected to the upper insulator 2 via a connector 5. The connector 5 comprises two mating semi-ring structures, fastened together with bolts to clamp and fix the positioning tube 3 to the upper insulator 2. The inner side of the semi-ring structures has anti-slip textures to effectively increase friction with the positioning tube 3 and prevent slippage. The other end of the positioning tube 3 extends to the outside of the device, providing horizontal support for the installation of subsequent components. The diagonal tie rod 4 is made of a metal rod with sufficient strength and toughness, with one end fixedly connected to the middle of the positioning tube 3 via a clamp 19. The clamp 19 tightly encircles the positioning tube 3, ensuring a stable connection, and its material is compatible with the positioning tube 3 to prevent damage. The other end of the diagonal tie rod 4 is fixed to the bracket 1 by bolt connection. The diagonal tie rod 4 is a telescopic structure, including an inner rod and an outer rod. The inner rod is nested inside the outer rod, and multiple positioning holes are provided on the inner and outer rods. The length of the diagonal tie rod 4 can be adjusted and fixed by inserting pins through the positioning holes to adapt to different installation heights and stress conditions, effectively sharing the external force borne by the positioning tube 3 and maintaining the structural balance of the device. The positioning support tube 6 is connected to the positioning tube 3 by welding to ensure the strength and stability of the connection. The welding part is specially treated to prevent cracks or incomplete welding. One end is connected to the positioning tube 3, and the other end extends downward to provide vertical support for the positioning device 8 and its related components. The adjusting device 7 is sleeved on the positioning support tube 6, and the adjusting device 7 and the positioning support tube 6 are slidably connected. It can move along the axial direction of the positioning support tube 6 to adjust the height position of the positioning device 8. The adjusting device 7 includes an adjusting nut and a locking nut. The adjusting nut is threaded into the positioner support tube 6. Rotating the adjusting nut allows the positioner 8 to move up and down along the positioner support tube 6. The locking nut is used to lock the adjusting nut after adjustment to prevent loosening and ensure the stability of the positioner 8. The positioner 8 is connected to the adjusting device 7 via a hinge connection. The hinge connection allows the positioner 8 to rotate within a certain angle range relative to the adjusting device 7, thereby achieving precise positioning of the contact line. The structural design of the positioner 8 conforms to aerodynamic principles, enabling it to maintain its stability and reduce swaying under the impact of airflow from a high-speed train.

[0023] The wire clamp 9, fixedly installed at the end of the locator 8, is used to clamp the contact wire. The wire clamp 9 and the locator 8 are connected by a thread for easy installation and removal. The wire clamp 9 is made of high-strength alloy material, possessing good conductivity and wear resistance, ensuring a firm grip on the contact wire during long-term use and preventing it from falling off or shifting. The lower insulator 10, similar to the upper insulator 2, is made of a material with excellent insulation properties and is installed at the lower part of the bracket 1, corresponding to the upper insulator 2, together providing insulation and support, further enhancing the stability of the device. The L-shaped mounting bracket 11 is fixedly connected to the bottom of the bracket 1 at one end by welding, and extends horizontally at the other end, providing an installation position for the control box bracket 12. The weld joint is reinforced to ensure reliable connection. The control box bracket 12 is fixedly installed on the horizontal end face of the L-shaped mounting bracket 11 by bolt connection, facilitating the installation and removal of the control box bracket 12. The design of the control box bracket 12 takes into account the size and weight of the control box 15, ensuring stable support for the control box 15.

[0024] The control box 15 is placed on the control box bracket 12, and a shock-absorbing pad is provided between the control box 15 and the control box bracket 12 to reduce the impact of vibration on the electronic components inside the control box 15. The control box 15 adopts a sealed design to prevent dust, moisture, etc. from entering and affecting the normal operation of electronic components. The control box 15 is equipped with indicator lights 16, display screen 17, and control buttons 18. The indicator lights 16 are used to display the working status of the device, such as normal operation and fault alarm; the display screen 17 is used to display relevant parameters, such as the position of the positioner 8 and the stress on the device; the control buttons 18 are used by the operator to input commands to achieve manual control of the device. The baffle 13 is installed at an appropriate position on the bracket 1 to prevent external debris from entering the device and protect the internal components from damage. The baffle 13 is made of corrosion-resistant material and can adapt to complex outdoor environmental conditions. The connecting pipe 14 serves as a transition between certain components of the device according to actual needs. Its material and size are selected according to the requirements of the connection part to ensure smooth and stable connection.

[0025] Working Principle: The support bracket 1 serves as the fundamental support structure for the entire device, securely installed in a predetermined position, providing a reliable mounting foundation for the upper insulator 2, lower insulator 10, and other components. The upper insulator 2 and lower insulator 10 not only provide electrical insulation, preventing current conduction to non-conductive components such as the support bracket, but also provide mechanical support, ensuring the structural stability of the entire device. The positioning tube 3 is connected to the upper insulator 2 via connector 5, forming a horizontally extending structure that provides a general positioning direction for the contact wire. One end of the diagonal tie rod 4 is fixed to the positioning tube 3 via clamp 19, and the other end is connected to the support bracket 1. The adjustable angle design and secure connection of the diagonal tie rod 4 effectively distribute the force borne by the positioning tube 3, ensuring the stability of the positioning tube 3 under various working conditions.

[0026] The positioner support tube 6 is welded to the positioner tube 3, providing a vertically downward support structure for the positioner 8. The adjusting device 7 is sleeved on the positioner support tube 6 and can move axially. The height of the positioner 8 can be precisely adjusted using the adjusting nut and locking nut on the adjusting device 7. The positioner 8 is hinged to the adjusting device 7, allowing it to rotate within a certain angle range. This enables it to flexibly adapt to the actual position and direction of the contact wire, ensuring accurate positioning and clamping of the wire.

[0027] The wire clamp 9 is fixed to the end of the positioner 8 to firmly clamp the contact wire. Its threaded connection with the positioner 8 facilitates installation and maintenance. When the contact wire is subjected to external force, such as contact and slippage of the pantograph of an electric locomotive, the wire clamp 9 can transmit the force to the positioner 8. The positioner 8 then distributes the force to the adjusting device 7 and the positioner support tube 6 through a hinge connection. Finally, the force is transmitted to the bracket 1 and the foundation structure through the entire device structure, ensuring the stability and reliability of the device. The control box 15 is mounted on the L-shaped mounting bracket 11 through the control box bracket 12. Its internal wireless communication module can communicate wirelessly with external devices to realize remote monitoring and control. Operators can input commands through the control buttons 18. Relevant information is displayed on the display screen 17, and the indicator lights 16 display the working status of the device in real time, such as power on / off and fault alarms, so that staff can understand the operation of the device in a timely manner and perform corresponding operations and maintenance.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
