Description

Technical Field

[0001] This utility model relates to the field of traffic signal equipment measurement technology, specifically a measurement device for urban rail transit signal equipment. Background Technology

[0002] Urban rail transit trains are all based on the moving block principle, which is based on precise train positioning technology using a track database. This is generally achieved through beacons and speed sensors. The positioning process is as follows: the position and direction of travel of the train are determined by reading the beacons. Then, the train position information is updated each cycle based on the distance traveled by the speed sensor. The train is located by matching the position of the corresponding beacon device in the track database, and corresponding safety protection measures are implemented.

[0003] Currently, existing urban rail transit signal equipment measurement devices typically involve wheels moving on guide rails, with encoders converting wheel rotation into distance to measure beacon distance. During measurement, debris such as fallen leaves, dust, and water on the track can cause the wheels to stop or slip, affecting wheel rotation and thus measurement data. This presents a problem of debris on the track affecting the wheels. Furthermore, the measurement device itself is heavy, requiring workers to move it up and down the track, posing a risk of injury from being pinched. Moving it is also inconvenient, and pushing it afterward can lead to physical exhaustion. Overall, the measurement device is difficult to move and install. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example Please see Figures 1 to 6 The present invention provides a technical solution including a mobile trolley 1, a fixed frame 9 fixedly connected to the lower part of the mobile trolley 1, a moving wheel 3 connected to the lower bearing of the fixed frame 9, a connecting frame 7 fixedly connected to one side of the fixed frame 9, a brush roller 8 connected to the internal bearing of the connecting frame 7, a connecting shaft of the brush roller 8 connected to the pulley of the transmission group 6, a drive gear of the transmission group 6 connected to the connecting shaft of the moving wheel 3, the lower parts of the brush roller 8 and the moving wheel 3 abutting against the guide rail 4, a fixed rod 13 provided at the lower part of the mobile trolley 1, a support rod 11 fixedly connected to one side of the fixed rod 13, a universal wheel 5 fixedly connected to the lower part of the support rod 11, a connecting shell 10 fixedly connected to the upper part of the mobile trolley 1, a fixed part of an electric push rod 12 fixedly connected inside the connecting shell 10, and a fixed rod 13 fixedly connected to the lower part of the movable end of the electric push rod 12.

[0017] Please refer to Figure 4 to Figure 5 The transmission group 6 consists of two pulleys, a transmission belt, a driving gear and a driven gear. The driven gear and the pulley are connected to the bearing of the fixed frame 9 through a connecting shaft. The moving wheel 3 and the brush roller 8 rotate in opposite directions through the transmission group 6.

[0018] Specifically, the transmission assembly 6 causes the moving wheel 3 to rotate, which in turn drives the brush roller 8 to rotate, thus cleaning the guide rail 4.

[0019] Please see Figures 1 to 2 A protective cover 2 is provided on the outside of the fixed frame 9 and the connecting frame 7. The transmission group 6 is located inside the protective cover 2, and the brush roller 8 is located at the front end of the moving wheel 3 at the front of the moving trolley 1.

[0020] Specifically, the protective cover 2 encloses the transmission assembly 6 to prevent it from being exposed to external influences. The brush roller 8 cleans the front guide rail 4 of the moving trolley 1.

[0021] Please refer to Figure 1 to Figure 2 The upper part of the mobile trolley 1 is equipped with a battery, a touch screen, a computer and a beacon detection device. An encoder 15 is fixedly connected to the inner side of the fixed frame 9. The encoder 15 is connected to the connecting shaft inside the mobile wheel 3.

[0022] Specifically, the battery powers the touchscreen display, computer, beacon detection device, and encoder 15 on the mobile trolley 1. The touchscreen displays measurement data. The computer calculates the data measured by the encoder 15 and transmits it to the touchscreen display. The beacon detection device detects the beacon position, providing the start and end points for the encoder 15's counting. The encoder 15 is fixed to the connecting shaft of the mobile wheel 3 via a flexible coupling.

[0023] Please see Figures 1 to 3 The upper part of the fixed rod 13 is fixedly connected to the limiting sleeve 14. The outer side of the limiting sleeve 14 is inserted into the interior of the connecting shell 10. The limiting sleeve 14, the electric push rod 12 and the connecting shell 10 are arranged in a linear array.

[0024] Specifically, the electric actuator 12 is connected to the battery via a wire. The extension and retraction of the electric actuator 12 are controlled by a touch-screen control panel. A mechanical lock is installed between the electric actuator 12 and the fixed rod 13 to prevent the measuring device from suddenly falling if the electric actuator 12 fails.

[0025] Please refer to Figure 2 to Figure 3 The limiting sleeve 14 fits closely inside the connecting shell 10, the support rod 11 and the fixing rod 13 are in the shape of an I-beam, and the electric push rod 12 is set inside the limiting sleeve 14.

[0026] Specifically, the limiting sleeve 14 is connected to the connecting shell 10 to limit the lateral movement of the fixing rod 13.

[0027] In use, the measuring device is installed on the guide rail 4, and the moving trolley 1 is manually pushed to move on the guide rail 4. The moving wheels 3 rotate on the guide rail 4. The encoder 15 is connected to the connecting shaft of the moving wheels 3 to calculate the number of rotations of the moving wheels 3 and then transmit it to the computer on the upper part of the moving trolley 1. After the beacon detection device detects the beacon position, it transmits the signal to the computer. The computer calculates the beacon distance by combining the encoder data and displays the result on the touch screen to complete the measurement. When the moving trolley 1 moves on the guide rail 4, a brush roller 8 is set at the front end of the moving wheels 3 at the front of the moving trolley 1. The brush roller 8 is connected to the fixing frame 9 of the moving wheels 3 through the connecting frame 7. The brush roller 8 cleans the upper part of the guide rail 4 in front of the moving wheels 3 to remove debris and prevent it from affecting the moving wheels 3. An encoder 15 is set on the inner side of each of the multiple moving wheels 3 for data comparison and to reduce errors. The connecting frame 7 and brush roller 8 effectively clean debris from the surface of the guide rail 4 at the front end of the moving wheel 3. The rotation of the moving wheel 3 drives the drive gear of the transmission group 6 via the connecting shaft. The drive gear drives the meshing driven gear, one side of which is fixedly connected to a pulley. The pulley drives another pulley via a transmission belt, which in turn drives the brush roller 8 to rotate in the opposite direction to the moving wheel 3. A protective cover 2 is installed on the outside of the transmission group 6 to prevent it from being affected by external factors. Through the coordinated arrangement of the transmission group 6 and the protective cover 2, the brush roller 8 can rotate synchronously with the moving wheel 3 during use, thus facilitating the cleaning of the guide rail 4 and achieving the purpose of cleaning debris from the track.

[0028] The moving wheels 3 of the trolley 1 are installed with the guide rail 4. During installation, the trolley 1 moves via the casters 5 to the middle of the guide rail 4. The electric push rod 12 is then extended via the touch screen control, pushing the fixed rod 13 downwards, causing the trolley 1 to move upwards relative to the guide rail 4, so that the bottom of the moving wheel 3 is higher than the guide rail 4. The moving wheel 3 is then aligned with the guide rail 4, and the electric push rod 12 is retracted, causing the trolley 1 to move downwards. The moving wheel 3 is supported by the guide rail 4, and the fixed rod 13 continues to move upwards, lifting the casters 5 off the ground, completing the installation. The electric push rod 12, support rod 11, fixed rod 13, and casters 5 facilitate the installation of the measuring device with the guide rail 4. When the electric push rod 12 extends, the limiting sleeve 14 moves inside the connecting shell 10, restricting the lateral position within the connecting shell 10 and preventing the fixed rod 13 from shifting laterally. A battery is installed on the upper part of the mobile trolley 1 to power the electric push rod 12. Through the sliding cooperation between the connecting shell 10 and the limiting sleeve 14, the fixed rod 13 and the support rod 11 in the supported state can be laterally limited. With the lifting action of the electric push rod 12, the measuring device can be lifted and moved, thus achieving the purpose of convenient handling and installation of the measuring device.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
