Description

Technical Field

[0001] This utility model relates to the field of railway track precision measurement technology, specifically to an electric track flatbed vehicle. Background Technology

[0002] Electric rail flatbed carts are a type of equipment specifically designed for railway track measurement and inspection. This equipment can accurately measure the geometric parameters of the track, such as gauge, level, elevation, and orientation, to ensure that the track meets safety and operational standards. By collecting track data, it can assess the degree of wear and damage to the track, providing a basis for track maintenance and repair.

[0003] When in use, electric rail flatcars are usually driven by a drive unit to move at a constant speed. During the movement of the electric rail flatcar, a detection device accurately measures the geometric parameters of the track, such as the track elevation, level, and gauge. The detection device transmits the detected data to a data acquisition device, which preprocesses the collected data and then transmits the processed data to a control device. The control device then performs a detailed analysis of the data to assess the condition of the track.

[0004] While existing electric rail flatbed vehicles can lock the rollers through electronic braking in emergencies to prevent slippage, the cost of electronic braking systems is high. In extreme weather conditions, such as extreme cold or heat, the performance of electronic braking systems may be affected, thus reducing braking effectiveness. Therefore, we propose an electric rail flatbed vehicle. Utility Model Content

It solves the problem that the performance of the electronic control braking system will be affected under extreme weather conditions.

[0023] The device also includes a fixing plate 3, a notebook 4, a mounting slot 8, a battery 9, and an inverter 10. The fixing plate 3 is located on the rear side of the outer arc surface of the mounting frame 2. The notebook 4 is located in the middle of the upper end of the mounting frame 2. The mounting slot 8 is located on the right side inside the base 1. The battery 9 is located on the left side of the bottom wall of the mounting slot 8.

[0024] The base 1 has a GNSS receiver 14 installed at its upper end. The GNSS receiver 14 is located on the right side of the mounting slot 8. The GNSS receiver 14 receives signals from the satellite navigation system in real time to determine the position (longitude, latitude and altitude) of the GNSS receiver 14 in three-dimensional space and the precise time information. Then the GNSS receiver 14 transmits the data to the notebook 4. The notebook 4 calculates and determines the precise position of the electric rail flatbed car on the railway track.

[0025] Servo motors 5 are respectively installed on the lower right side of the base 1. The left end of the output shaft of the servo motor 5 is fixedly connected to the right end of the left roller 6. The input end of the servo motor 5 is electrically connected to the output end of the laptop 4. The operator starts to run the servo motor 5 through the control of the laptop 4. The output shaft of the servo motor 5 drives the left roller 6 to rotate, thereby driving the electric track flatbed to move.

[0026] The base 1 has a fixed seat 11 at its upper end, which is located between the left end of the mounting groove 8 and the right end of the mounting frame 2. The fixed seat 11 has a total station 12 at its upper end. The input end of the total station 12 is electrically connected to the output end of the laptop 4.

[0028] The working principle of the electric rail flatbed provided by this utility model is as follows: When using the electric rail flatbed, first place the electric rail flatbed on the upper end of the track, so that the roller 6 is in contact with the track. The GNSS receiver 14 receives the signal of the satellite navigation system in real time to determine the position (longitude, latitude, and altitude) of the GNSS receiver 14 in three-dimensional space and the precise time information. Then, the GNSS receiver 14 transmits the data to the laptop 4. The laptop 4 calculates and determines the precise position of the electric rail flatbed on the railway track. Then, the operator rotates the adjusting wheel 79. The adjusting wheel 79 rotates... During the process, the screw 78 will rotate. As the screw 78 rotates, it will drive the adjusting seat 75 to move to the left via a threaded connection. As the adjusting seat 75 moves to the left, it will exert a pulling force on the mounting seat 76 via the transmission rod 77. This will cause the transmission rod 77 to drive the connecting plate 72 upwards via the mounting seat 76. The connecting plate 72 will then drive the brake shoe 74 upwards via the fixing rod 73, thus separating the brake shoe 74 from the left roller 6. Afterwards, the operator will control the servo motor 5 via the laptop 4. The output shaft of the servo motor 5 will drive the left roller 6 to rotate, thereby driving the electric track leveling... The flatbed cart moves, and the operator moves along with it. During this movement, the operator controls the total station 12 via laptop 4. The total station 12 is used to accurately measure the geometric parameters of the track, such as elevation, level, and gauge. The total station 12 transmits the measured data to the data acquisition box 13, which preprocesses the collected data and then transmits the processed data back to laptop 4. Laptop 4 then performs detailed analysis of the data to assess the track condition. In case of an emergency during the measurement process, the operator... The author controls the servo motor 5 by using the notebook 4 to stop it. Then, the operator rotates the adjustment wheel 79. During the rotation of the adjustment wheel 79, the screw 78 rotates. During the rotation of the screw 78, the adjustment seat 75 moves to the right through the threaded connection. During the movement of the adjustment seat 75 to the right, the transmission rod 77 provides a thrust to the mounting seat 76. This causes the transmission rod 77 to move the connecting plate 72 downward through the mounting seat 76. The connecting plate 72 moves the brake shoe 74 downward through the fixing rod 73, so that the brake shoe 74 contacts the roller 6, generating friction and preventing the roller 6 from slipping.

[0029] It is worth noting that, in the above embodiments, the notebook computer 4 can be an X600pro, the servo motor 5 can be an ECMA-C20604RS, the battery 9 can be a GFMD-C, the inverter 10 can be a TS-700-212B, the total station 12 can be a 442R10U, the data acquisition box 13 can be an ABOX5000-12S, and the GNSS receiver 14 can be a TH-GS1. The notebook computer 4 controls the servo motor 5, the total station 12, and the GNSS receiver 14 using methods commonly used in the prior art.
