Technical Field

[0001] This utility model relates to an intelligent bogie pushing AGV during the maintenance of railway freight cars. Background Technology

[0002] Bogie maintenance is a crucial part of railway freight car maintenance. With the large-scale operation of heavy-haul high-speed railway freight cars in railway transportation, higher standards have been set for the quality, performance, and maintenance requirements of the running gear. As a key component of the railway freight car running gear, the importance of bogie maintenance is becoming increasingly prominent.

[0003] Currently, in the maintenance work of bogies in domestic depots, the transfer of bogies is still carried out manually. In order to improve work efficiency, reduce labor intensity, reduce transportation costs, eliminate safety hazards, and ensure the efficient and smooth progress of bogie maintenance work, intelligent bogie pushing AGVs will be added. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent bogie pushing AGV that improves work efficiency and reduces labor intensity.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bogie intelligent push AGV is characterized by: including a body shell and a decorative cover plate, six omnidirectional drive wheels, two swing arm pushers, a battery and a control unit are installed in the body shell, magnetic strip sensors are installed on the front and rear plates of the body shell respectively, obstacle avoidance radar is provided on the front and rear parts of the decorative cover plate respectively, warning lights are provided at the four corners of the decorative cover plate, and control buttons are provided at the rear of the decorative cover plate.

[0007] The six omnidirectional drive wheels are arranged in threes on both sides of the vehicle body bottom shell. The two omnidirectional drive wheels on the front side are staggered front to back, and the two omnidirectional drive wheels on the rear side are staggered front to back.

The bearing is installed on the base. The driven shaft passes through the bearing. A driven gear that meshes with the drive gear is installed at one end of the driven shaft. The pusher is installed on the driven shaft.

[0009] The height H of the intelligent push AGV with bogie is 100mm.

[0010] The pusher includes a square tube, one end of which is fixed to the driven shaft, and two rollers are installed on a pin between the lugs formed at the other end. The two rollers abut against the axle of the bogie.

[0011] The other end of the driven shaft is provided with a baffle, and a proximity switch is installed on the bottom shell of the vehicle body corresponding to the baffle.

[0012] The decorative cover plate is made of 1.5mm thick Q235 sheet metal, bent and welded.

[0013] The top wall of the decorative cover plate is bent and welded to form a U-shape, and the height h of the concave part of the body of the intelligent push AGV of the bogie is 60mm.

[0024] The following examples illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention.

[0025] like Figure 1 and Figure 2As shown, this utility model discloses an intelligent bogie pushing AGV, including a body shell 1 and a decorative cover plate 2. Six low-profile omnidirectional drive wheels 3, two swing arm pushers 4, a battery 5, and a control unit 6 are installed in the body shell via screws. The battery is a ternary lithium battery, and the control unit is a PLC control system. Magnetic strip sensors 7 are installed on the front and rear panels of the body shell, and RFID sensors 8 are also installed on the body shell. The magnetic strip sensors and RFID sensors are connected to the control unit. Based on the magnetic strip sensors and RFID sensors, the AGV can travel back and forth on a designated route. Obstacle avoidance radars 9 are installed at the front and rear parts of the decorative cover plate. The obstacle avoidance radars identify the bogies to be pushed, and when the obstacle avoidance radars detect equipment or personnel on the work route, the AGV automatically stops. After the personnel or equipment leave, the AGV automatically starts and continues to move forward. The obstacle avoidance radars are connected to the control unit, and when the obstacle avoidance radars are operating, the control unit controls the movement and stopping of the omnidirectional steering wheels. Warning lights 10 are located at the four corners of the decorative cover plate, and manual intervention control buttons 11 are located at the rear of the decorative cover plate. These control buttons include a start / stop button, an emergency stop button, and a manual control button for the rocker arm pusher. Both the warning lights and control buttons are connected to a control unit, which controls the start and stop of the omnidirectional drive wheels and the rocker arm pusher. This bogie is a 6-steering-wheel bogie.

[0026] like Figure 2 As shown, the six omnidirectional drive wheels are arranged in a 3:3 interval on both sides of the vehicle's underbody. The two omnidirectional drive wheels on the front side are staggered, as are the two omnidirectional drive wheels on the rear side. The two omnidirectional drive wheels in the middle can be aligned. The six omnidirectional drive wheels form an isosceles trapezoidal shape. When the AGV crosses the track, the first set of omnidirectional drive wheels enters the track groove first. The remaining five sets of omnidirectional drive wheels continue to provide support and sufficient driving force, preventing the first set of omnidirectional drive wheels from sinking while propelling the vehicle forward. After the first set of omnidirectional drive wheels crosses the track groove, there are support wheels on both sides of the track to ensure that the other omnidirectional drive wheels do not fall into the groove. This staggered arrangement of the six sets of omnidirectional drive wheels ensures smooth track crossing for the AGV. The key to this application is the staggered arrangement of the six omnidirectional drive wheels, which ensures stable operation. The height H of the AGV's body is 100mm. The height h of the body recess of the intelligent bogie-pushing AGV is 60mm.

[0027] like Figure 3As shown, two swing arm pushers 4 are correspondingly arranged on the left and right sides of the vehicle body's underbody, located between the two omnidirectional drive wheels on the same side. Each swing arm pusher includes a drive motor 41, a drive gear 42, a driven gear 43, a driven shaft 44, a base 45, a bearing 46, and a pusher 27. The output shaft of the drive motor is connected to the drive gear. There are two bases, spaced apart and aligned. Bearings are installed on the bases, and the driven shaft passes through both bearings. A driven gear meshing with the drive gear is installed at one end of the driven shaft, and the pusher is installed on the driven shaft between the two bases. Specifically, the pusher includes a square tube. One end of the square tube is fitted onto the driven shaft, and two rollers are installed on a pin shaft formed by two ear plates at the other end. The rollers abut against the axle of the bogie. After the AGV reaches the designated position of the bogie to be pushed, the pusher is rotated and raised under the drive of the drive motor to push the bogie. Furthermore, the other end of the driven shaft is provided with a baffle, and a proximity switch 48 is installed on the bottom shell of the vehicle body corresponding to the baffle. When the pusher is raised and lowered into position, the proximity switch controls the drive motor to stop rotating. The proximity switch is connected to the control unit, and the control unit controls the drive motor to stop rotating.

[0028] The decorative cover plate is made of 1.5mm thick Q235 sheet metal, bent and welded. The top wall of the decorative cover plate is bent and welded into a U-shape. The top plate of the decorative cover plate is equipped with an operation screen 12. The connection of the electrical control system uses existing mature technologies and will not be described in detail.
