[0007] Furthermore, the motor unit is fixed on the corresponding fire truck body.

[0008] Furthermore, a transmission mechanism is provided between the output shaft of the motor unit and the rotating bracket for reducing speed and increasing torque.

[0009] Furthermore, the platform also includes a slide support frame, which is fixed on the corresponding fire truck body and is used to support the retracted main lifting slide.

[0010] Furthermore, a ground contact roller is provided at the end of the main lifting slide to facilitate ground contact.

[0011] Furthermore, several rollers are provided on the inner side of the flipping plate member, and the main lifting slide is arranged on the rollers to achieve sliding cooperation with the flipping plate member.

[0018] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0019] As Figures 1 to 3 shown, an electric lifting platform, the platform includes a main lifting slide 1, one end of the main lifting slide 1 is rotatably connected to the rotating bracket 3, the main lifting slide 1 is integrally slidably arranged on the flipping plate member 6, the flipping plate member 6 is rotatably connected to the edge of the corresponding fire truck body 7, one end of the rotating bracket 3 is fixedly connected to the output shaft of the motor unit 4, so that it rotates around the output shaft as the rotation axis under the drive of the motor unit 4, and while driving the main lifting slide 1 to slide along the flipping plate member 6, it pushes the flipping plate member 6 to perform a flipping action for the lowering to the ground or lifting and recycling of the main lifting slide 1.

[0020] The motor unit 4 is fixed on the corresponding fire truck body 7.

[0021] A transmission mechanism 5 is provided between the output shaft of the motor unit 4 and the rotating bracket 3 for speed reduction and torque increase.

[0022] The platform further includes a slide support frame 2, the slide support frame 2 is fixed on the corresponding fire truck body 7, and is used to support the retracted main lifting slide 1 to ensure the balance and limit of the placement of the entire platform mechanism.

[0023] The end of the main lifting slide 1 is provided with a ground-touching roller 8 for facilitating ground-touching and rolling transportation.

[0024] As Figure 2 shown, several rollers 9 are provided on the inner side of the flipping plate member 6, and the main lifting slide 1 is arranged on these rollers 9 to achieve a sliding fit with the flipping plate member 6.

[0025] The operation process and principle of the present utility model

[0026] Firstly, power is provided by the motor unit 4 to drive the transmission mechanism 5 to perform a rotational motion. The transmission mechanism 5 drives the rotating bracket 3 to rotate, and the rotating bracket 3 is linked with the main lifting slide 1. The main lifting slide 1 essentially makes a circular motion around the center of the motor unit 4. Since the main lifting slide 1 is slidably / rollably connected to the flipping plate member 6 through several rollers 9, the main lifting slide 1 can be linked with the flipping plate member 6 through its own track, thereby realizing the slow descent of the ladder frame.

[0027] As Figure 2 shown, when the lifting platform is in the landed state, the motor unit 4 stops working at this time, and the user can use the ladder on the ground at this time. After use, the motor unit 4 is reversed to realize the reset action of this lifting platform.

[0028] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
