Description

Technical Field

[0001] The invention mainly relates to the technical field of horse stools, and in particular to an intelligent carriage horse stool used for train maintenance. Background Art

[0002] In the process of train carriage maintenance, in order to raise the carriage for maintenance and inspection work, it is usually necessary to use a horse stool. However, the traditional method is to place the horse stool under the carriage manually, which has some obvious disadvantages.

[0003] First of all, manually placing horse stools requires a lot of manpower and time. For a carriage, at least 4 horse stools are required, which means that multiple workers are required to operate at the same time, and the process of placing horse stools may be cumbersome and time-consuming, affecting the efficiency of maintenance work. Secondly, there are certain safety risks in manually placing horse stools. Workers need to operate under the carriage and may face dangers such as falling from heights and being hit by objects. In addition, if the horse stool is placed unstably or loosely, it may also cause the carriage to tilt or collapse, further increasing safety risks. In addition, the accuracy and stability of manually placed horse stools are also difficult to guarantee. Due to the different operating levels and experience of each worker, the position and height of the horse stool may be inconsistent, affecting the stability of the carriage and the quality of maintenance.

[0004] So we proposed a method to solve the above problems. Summary of the invention

[0020] See attached Figures 1 to 7 A smart carriage horse stool used for train maintenance comprises a horse stool driving chassis 1, a walking mechanism 2 is arranged at the lower end of the horse stool driving chassis 1, a horse stool lifting device 4 is arranged at the upper end of the horse stool driving chassis 1, a horse stool body 3 is arranged on the output end of the horse stool lifting device 4, the shape of the horse stool body 3 is a trapezoidal platform, and a navigation laser radar 32, an obstacle avoidance laser radar 35 and a plurality of ultrasonic sensors 34 are arranged on the front and rear surfaces of the horse stool body 3. A connected control board 5 and a battery 6 are also arranged on the horse stool driving chassis 1, and the control board 5 is connected to the walking mechanism 2, the horse stool body 3 and the horse stool lifting device 4.

[0021] The control panel 5 receives signals from various sensors, processes and sends control instructions, and coordinates the work of various mechanisms. The control panel 5 receives signals from the navigation laser radar 32, the obstacle avoidance laser radar 35, and the ultrasonic sensor 34, calculates the walking path, lifting height and other parameters of the horse stool according to the preset program and algorithm, and sends instructions to the walking mechanism 2, the horse stool lifting device 4, etc., to realize the functions of automatic walking, lifting and obstacle avoidance of the horse stool.

[0022] A top plate 31 is provided at the upper end of the horse stool body 3, and mounting frames 33 are fixedly mounted on both the front and rear surfaces of the horse stool body 3, and a plurality of ultrasonic sensors 34 are arranged on the mounting frames 33. The top plate 31 is a rubber anti-slip plate to prevent the train carriage from sliding.

[0023] A number of operating buttons 36 are provided in front of the horse stool body 3, and the operating buttons 36 are connected to the control panel 5. The start and stop of the walking mechanism 2 and the horse stool lifting device 4 can be manually controlled through the operating buttons 36. The battery 6 is connected to the wireless charging antenna 24, and the wireless charging antenna 24 is provided at the lower end of the horse stool driving chassis 1. The wireless charging antenna 24 can realize automatic wireless charging. The battery 6 provides power support for each mechanism of the intelligent carriage horse stool. The battery 6 stores electrical energy, and when the horse stool needs to work, it provides the required power for the walking mechanism 2, the horse stool lifting device 4, the control panel 5, etc.

[0024] The horse stool lifting device 4 includes an electric lifting cylinder 41, a cushion block 44 is arranged at the center of the upper end of the horse stool driving chassis 1, the output end of the electric lifting cylinder 41 is rotatably connected to the first connecting seat 42, the lower end of the electric lifting cylinder 41 is rotatably connected to the second connecting seat 43, the first connecting seat 42 is fixed to the lower end of the lifting plate 45, and the second connecting seat 43 is fixed to the upper end of the cushion block 44. A plurality of guide shafts 47 are fixedly installed on the upper end of the horse stool driving chassis 1, a limit plate 46 is fixedly installed on the top end of the guide shaft 47, a linear bearing 48 is arranged on the lifting plate 45, and the linear bearing 48 is slidably installed on the guide shaft 47 up and down.

[0025] The electric lifting cylinder 41 receives the command from the control panel 5 and starts working. The output end of the electric lifting cylinder 41 extends or retracts, and drives the lifting plate 45 to move up and down along the guide shaft 47 through the first connecting seat 42. The up and down movement of the lifting plate 45 drives the horse stool body 3 to rise and fall together through the connecting block 38, thereby lifting or lowering the horse stool body 3. Through the control of the electric lifting cylinder 41, the lifting height of the horse stool body 3 can be accurately adjusted to meet the needs of different maintenance tasks.

[0029] 3. The control panel 5 plans the walking path according to the sensor information and sends instructions to the walking mechanism 2 to make the horse stool move along the planned path.

[0030] 4. During the walking process, the obstacle avoidance laser radar 35 and several ultrasonic sensors 34 monitor the surrounding environment in real time. When an obstacle is detected, the control board 5 adjusts the walking direction or takes obstacle avoidance measures in time.

[0031] 5. When the horse stool reaches the designated position, the control panel 5 controls the horse stool lifting device 4 to lift the horse stool body 3 to a suitable height.

[0032] 6. Maintenance personnel carry out maintenance and inspection work on trains.

[0033] 7. After the maintenance is completed, the control panel 5 controls the horse stool lifting device 4 to lower the horse stool body 3, and then controls the walking mechanism 2 to move the horse stool to the next maintenance position or return to the starting position.

[0034] Through the coordinated work of the above mechanisms, the intelligent carriage horse stool can realize functions such as automatic walking, lifting and obstacle avoidance, thereby improving the efficiency and safety of train maintenance. At the same time, the application of multiple sensors such as navigation laser radar 32, obstacle avoidance laser radar 35 and ultrasonic sensor 34 enables the horse stool to adapt to different working environments and complex situations.
