Embodiment

[0023] As Figures 1 to 5As shown in the figure, the utility model discloses an engine working platform. The adopted technical solution is as follows: it includes a platform assembly 1. The frame of the platform assembly 1 is welded by high-strength rectangular steel pipes. A pedal is installed on the frame, and kick plates are installed around the pedal. A guardrail is bolted to the platform assembly 1, and a ladder assembly 7 is also bolted to it for climbing onto the platform assembly 1 from the ground. To facilitate movement and compatibility with the maintenance of engines of different heights, column legs 6 are bolted to the bottom of the platform assembly 1. The main body of the column leg 6 is a support column. One end of the support column is bolted to the bottom surface of the platform assembly 1, and the other end is bolted to a fixing device. The fixing device is a square tubular structure. The fixed end of the servo cylinder is installed in the fixing device. The output end of the servo cylinder is vertically downward and is connected with a steering wheel through a flange and bolts. To be able to control the movement of the working platform, a control system 8 is arranged below the platform assembly 1. The control system 8 uses a PLC controller and is electrically connected to a lithium battery pack. To facilitate human-machine interaction, a touch screen is installed on the platform assembly 1, and a remote controller is set. Both the touch screen and the remote controller are electrically connected to the PLC controller. The control system 8 includes two independent systems: a walking control system and a lifting control system. To improve the safety during self-walking, an optoelectronic obstacle avoidance sensor is installed on the platform assembly 1. The optoelectronic obstacle avoidance sensor is electrically connected to the walking control system. The walking control system is also electrically connected to a walking controller and a walking driver. The walking driver is electrically connected to the steering motor and the walking traction motor of the steering wheel. The lifting control system is electrically connected to a lifting controller and a lifting driver. The lifting driver is electrically connected to the servo motor of the servo cylinder, as Figure 6 shown. The height of the platform assembly 1 can be controlled by the servo cylinder, and the omnidirectional movement of the working platform can be achieved by controlling the steering wheel: lateral movement, longitudinal movement, and in-situ rotation.

[0024] To further improve the stability of the platform assembly 1, a crossbeam support frame 3 and a vertical beam support frame 4 are bolted between the support columns of adjacent column legs 6. The platform assembly 1 is connected to the crossbeam support frame 3 and the vertical beam support frame 4 through a vertical support frame 2, so that the weight of the personnel, equipment, etc. above the platform assembly 1 acts on the crossbeam support frame 3 and the vertical beam support frame 4 through the vertical support frame 2, and then acts on the column legs 6. An inclined support frame 5 is hinged between the crossbeam support frame 3 and the fixing device, and an adjustable inclined support assembly 9 is hinged between the bottom surface of the platform assembly 1 and the fixing device. The adjustable inclined support assembly 9 is as Figure 5As shown in the figure, it includes a rod body 901, a first connecting sleeve 904 and a second connecting sleeve 905. The middle part of the rod body 901 is set as a prism for easy engagement with a wrench. The two ends of the rod body 901 are respectively provided with a first screw rod 902 and a second screw rod 903. The thread rotation directions of the first screw rod 902 and the second screw rod 903 are opposite. One end of the first connecting sleeve 904 is hinged to the bottom surface of the platform assembly 1, and the other end surface has a first threaded hole. The first screw rod 902 is engaged in the first threaded hole. One end of the second connecting sleeve 905 is hinged to the fixing device, and the other end surface is provided with a second threaded hole. The second screw rod 903 is engaged in the second threaded hole. By using a wrench to hold the prism section and turn it, the first connecting sleeve 904 and the second connecting sleeve 905 can move synchronously in the opposite direction along the axis without rotating.

[0025] In order to be compatible with the protruding structure under the engine, a sunken platform 101 is also provided on the platform assembly 1. The sunken platform 101 includes an oil box 103. The cross-section of the oil box 103 is a concave trapezoid, and the bottom surface is inclined. A grille 102 is erected on the oil box 103. The grille 102 is lower than the adjacent platform assembly 1. In order to facilitate the discharge of the oil collected in the oil box 103, a drain port is provided at the lowest point of the bottom surface of the oil box 103. A manual ball valve is installed on the drain port. The grille 102 and the oil box 103 are in sliding contact and can be removed.

[0026] In order to prevent the working platform from hitting the vehicle during movement and causing losses, a circle of anti-collision strips 10 are installed on the edge of the platform assembly 1 by screws. The anti-collision strips 10 are rubber blocks. In order to facilitate the access to tools, a tool box 11 is provided on the guardrail of the platform assembly 1.

[0027] The working principle of the present utility model:

[0028] The staff climbs onto the platform assembly 1 through the ladder assembly 7. The lithium battery pack supplies power to the control system 8. The staff operates the human-computer interaction system on the touch screen or operates the remote control to make the engine working platform move under the engine of the vehicle to be repaired. During movement, the PLC controller of the walking control system controls the steering motor and the walking traction motor of the steering wheels to work. The motors of all steering wheels act synchronously. The walking traction motor drives the walking wheels to move forward. The PLC controller detects the surrounding environment through the photoelectric obstacle avoidance sensor to prevent collisions. After reaching under the target engine, the staff operates the human-computer interaction system on the touch screen or operates the remote control to make the PLC controller of the lifting control system control the servo electric cylinders to extend synchronously, pushing the platform assembly 1 to rise to a suitable height, and the protruding part under the engine is above the sunken platform 101.

[0029] The staff takes out the tools in the tool box 11 to disassemble the engine housing, and the engine oil leaking out is collected in the oil box 103 through the grille 102. If there is too much oil in the oil box 103, the ball valve on the drain port can be opened to drain the oil and clean it in time. If there is less oil, after the engine repair and replacement work is completed, the grille 102 can be removed to clean the oil box 103.
