Description

Technical Field

[0001] The utility model belongs to the technical field of contact network pillar inclination measurement, and in particular relates to a contact network pillar inclination rapid detection device. Background Art

[0002] In reality, there are many reasons for the deformation of contact network pillars. For example, since the line is erected in the air, it needs to bear the weight, wind, rainstorm, ice and snow and other mechanical forces, which causes the deformation of some tower frames. Or due to various reasons, the tower base is unstable, the tower body is tilted, and the contact network pillars are unevenly stressed and deformed. Both of the above situations may affect the normal operation of the line and cause corresponding losses. Therefore, deformation detection of contact network pillars is an indispensable part of the entire transmission line.

[0003] The existing measurement technologies mainly include plumb bob method and theodolite measurement method.

[0004] Plumb method: Workers climb to the top of the transmission overhead wire pillar and measure by placing a plumb line to the ground. The plumb method for measuring the inclination of railway overhead wire pillars has some disadvantages: The measurement accuracy of the plumb method is limited by the operator's technical level and measuring tools, and may not be enough to capture slight changes in the inclination of the pillar, especially in engineering measurement scenarios that require high precision. The plumb method requires a certain amount of time and human resources, especially when measuring multiple pillars in a large area. This may cause the measurement process to be time-consuming and increase the cost of the work. The plumb method requires operators to manually measure and record data, which may introduce human errors. Automated measurement methods may be more suitable for some engineering measurement tasks that require high accuracy and efficiency.

[0005] Theodolite measurement method: First, fix the theodolite at a certain distance along the center line of the transmission overhead line pillar, align the crosshairs in the theodolite lens barrel with the top of the overhead line pillar, then fix its horizontal rotation direction and move the theodolite lens barrel downward. Then fix the theodolite at the same distance from the center line of the transmission overhead line pillar in the horizontal direction of the line to measure the data.

[0006] Theodolite surveying method has the following disadvantages for measuring the inclination of railway contact network pillars: The accuracy of theodolite surveying method may be limited by the equipment itself and the technical level of the operator. The accuracy of the measurement may not be enough to capture small changes in the inclination of railway contact network pillars. Surveying with theodolite may take a long time, especially when surveying over a large area. This may cause interruption to railway operations or require additional time and resources. Theodolite surveying method requires professional personnel for operation and data processing, which may result in high labor costs. Utility Model Content

It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the relevant utility model are shown in the accompanying drawings.

[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] The utility model provides a contact network support tilt rapid detection device, referring to Figure 1 The contact network pillar inclination rapid detection device includes a laser emitting component 1, a laser receiver 2 and a positioning bracket 3.

[0037] The laser emission assembly 1 is installed on the contact network pillar, refer to Figure 2 , a laser emitting assembly 1 mounting frame 11 and a laser emitter 12 connected to a contact network support through the mounting frame 11.

[0038] The mounting frame 11 includes a mounting plate 111, which is in a long strip shape. An adjustment slot 112 is provided on the mounting plate 111. The adjustment slot 112 is a T-shaped slot, and the adjustment slot 112 penetrates the mounting plate 111 along the length direction of the mounting plate 111. A mounting slot 113 is provided on the mounting plate 111, and the mounting slot 113 penetrates the mounting plate 111. The mounting slot 113 penetrates the mounting plate 111 along the thickness direction of the mounting plate 111, and the laser emitter 12 is installed in the mounting slot 113. The mounting slot 113 is a strip-shaped slot, which is arranged along the length direction of the mounting plate 111. When the laser emitter 12 is installed in the mounting slot 113, the upper and lower edges of the laser emitter 12 are embedded in the adjustment slot 112, so that the laser emitter 12 can adjust its position along the adjustment slot 112.

[0039] Clamping plates 114 are installed on both sides of the mounting plate 111, and one side of the clamping plate 114 is embedded in the adjustment groove 112 to achieve a sliding connection between the clamping plate 114 and the mounting plate 111, and the clamping plate 114 is arranged vertically to the mounting plate 111. The two clamping plates 114 are used to clamp the contact network pillar, so that the mounting frame 11 is installed on the contact network pillar.

[0040] A fixing plate 115 is installed on one side opposite to the two clamping plates 114 . The fixing plate 115 is connected to the clamping plates 114 via fixing bolts 116 . The clamping plates 114 are parallel to the fixing plate 115 .

[0041] When installing the mounting frame 11 on the contact network pillar, first adjust the distance between the two clamps 114 so that the two clamps 114 can clamp the contact network pillar, then use the clamps 114 and the fixing plates 115 to clamp the contact network pillar, and use the fixing bolts 116 to fix the clamps 114 and the fixing plates 115, so that the clamps 114 and the fixing plates 115 can firmly install the mounting frame 11 on the contact network pillar, completing the installation of the laser emitting assembly 1 on the contact network pillar.

[0042] A swivel hook is provided at the edge of the clamping plate 114 , and the swivel hook is away from the mounting plate 111 and is hooked on the contact network support.

[0043] A level meter 13 is also fixedly connected to the mounting plate 111 and arranged on the upper side of the mounting plate 111. By reading the reading of the level meter 13, the mounting frame 11 is adjusted to be horizontal, thereby avoiding the device fixed tilt caused by the contact network support.

[0044] The laser transmitter 12 is used to emit laser light to ensure that the detection device can be directly in front of the measurement pillar.

[0045] Fix the laser emitting assembly 1 on the contact network pillar to ensure that it is stable and pointing to the target area. Adjust the angle of the laser positioning assembly to ensure that the laser beam accurately points to the area to be measured. Start the laser emitting assembly 1 and start emitting the laser beam. The laser beam will provide a clear measurement reference, which will help to position the measuring instrument more accurately. According to the position of the laser beam, adjust the position of the measuring instrument to align it with the laser reference. This can be achieved by observing the projection of the laser on the measuring instrument or using auxiliary tools. When the measuring instrument is aligned with the laser reference, start the measurement process. At this point, laser positioning provides an accurate spatial reference, which helps to ensure the accuracy of the measurement. During the measurement process, the position of the measuring instrument can be monitored in real time through the reference point provided by the laser emitting assembly 1. This helps to detect and correct any deviations in a timely manner.

[0046] The laser receiver 2 is used to receive laser light and cooperate with the laser emitting assembly 1 to align the vertical position of the equipment. When the laser is irradiated on the surface of the laser receiver 2, the laser receiver 2 will emit a prompt sound. Since the laser emitting assembly 1 is perpendicular to the plane where the contact network pillar is located, when the laser receiver 2 emits a prompt sound, the measuring device is facing the contact network pillar to be measured, thereby ensuring the accuracy of the measurement result caused by the deviation of the measurement position.

[0047] Reference Figure 3 The positioning bracket 3 is selected as a triangular bracket, which is a stable supporting structure for fixing the detection device. The positioning bracket 3 provides three fulcrums, so that the detection device can be stably placed on the positioning bracket 3 in a balanced state. The laser receiver 2 is fixedly connected to the top of the positioning bracket 3 and cooperates with the laser emission component 1 to align the vertical position of the device.

[0048] The contact network support inclination rapid detection device also includes an image analysis detection device 5 and an instrument box 4.

[0049] The image analysis and detection device 5 includes a start switch, a camera, a horizontal roll angle sensor, a touch screen, and a Nano controller. The working principle is described as follows:

[0050] The user starts the measurement box by starting the switch inside the measuring device. At this point, the Nano controller starts running, and the camera, horizontal roll angle sensor, etc. start working. The camera starts capturing images of the surrounding environment. These images will be used for the deep image detection algorithm and the image used to depict the baseline will be displayed on the touch screen. At this time, the horizontal roll angle sensor provides real-time data about the tilt of the measurement box by measuring the tilt angle of the measurement box relative to the horizontal plane. These data are processed by the Nano controller. The Nano controller uses the deep image detection algorithm to process the images captured by the camera, accurately depict the baseline, and detect the angle of the contact network pillar in real time. This helps to provide intuitive and visual measurement results. In addition, the Nano controller integrates the tilt angle data of the horizontal roll angle sensor and the results of the deep image detection algorithm to form complete measurement data. These data will be displayed on the touch screen to provide users with detailed measurement information. Users can interact with the Nano controller through the touch screen to view real-time measurement data, adjust parameters, or perform other operations. This provides real-time monitoring and control of the measurement process. When the measurement is completed or the user needs to stop the measurement, the operation of the measurement box can be stopped through the touch screen.

[0051] Through the above operations, the integrated measurement box can perform tilt measurement in real-time monitoring, providing accurate data and intuitive measurement results. The entire measurement process is highly automated and user-friendly, suitable for railway maintenance personnel to quickly and accurately detect the tilt of the contact network pillars.

[0052] The instrument box 4 is composed of a box body, a pulley, a handle, and a sponge pad inside the box. The instrument box 4 provides effective external protection to prevent industrial-grade measuring instruments from being damaged by the external environment, vibration and collision, thereby extending the service life of the instrument. The protective box is equipped with pulleys and handles, making it easy to carry the instrument, and the user can easily move the instrument to different work sites or locations. The design of the instrument box 4 provides a certain degree of dust and moisture-proof function to ensure that the instrument remains dry and clean during storage and transportation. With the reasonable use of sponge pads, the instruments can be placed in the box in an orderly manner, which helps to keep the workplace clean and tidy and reduce the risk of loss and damage. The instrument box 4 provides a dedicated storage space, which helps to organize and manage instruments, save storage space, and make the work area more compact. The industrial-grade measuring instrument protective box can not only ensure the safety and reliability of the instrument, but also improve work efficiency, making the instrument more flexible and convenient to use in different work scenarios.
