[0022] The utility model provides Figures 1 to 4 The illustrated embodiment of a lifting support platform device for steel grid installation comprises a lifting support platform frame 1, the bottom of which is fixedly connected to a support frame 2. Circular holes are formed at the four corners of the bottom of the support frame 2, and a movable frame 9 is rotatably connected to the inside of the circular holes. The bottom of the movable frame 9 is rotatably connected to a roller 10.

[0023] During specific use, the lifting support platform device is moved to the steel grid installation station through the cooperation of the moving frame 9 and the roller 10.

[0024] To improve the stability of the lifting support platform device during use, a through slot is provided at the bottom end of the support frame 2. A cylinder 5 is rotatably mounted within the through slot, and a slide column 6 is rotatably connected to the inside of the cylinder 5. A steering support plate 7, which is used to expand the support area, is fixedly connected to the bottom of the slide column 6. A slide plate 3 is slidably mounted within the support frame 2, and the top end of the cylinder 5 is fixedly connected to the slide plate 3. A first electric push rod 4 is fixedly connected to the lower surface of the slide plate 3, and the end of the first electric push rod 4 away from the slide plate 3 is fixedly connected to the upper surface of the bottom of the support frame 2.

[0025] A circular groove is provided on the movable frame 9, and a pressure rod 11 is provided inside the circular groove. The inner diameter of the circular groove is larger than the outer diameter of the pressure rod 11, which does not affect the rotation of the movable frame 9. The top end of the pressure rod 11 is fixedly connected to the slide 3, and the bottom end of the pressure rod 11 cooperates with the roller 10.

[0026] After moving to the steel grid installation station, adjust the angle of the lifting support platform device, start the first electric push rod 4, control the telescopic end of the first electric push rod 4 to extend and retract, drive the slide plate 3 to move downward, thereby driving the cylinder 5, the slide column 6, and the steering support plate 7 to move downward, and the steering support plate 7 abuts against the ground, expanding the support area and improving the stability of use.

[0027] At the same time, the downward movement of the slide plate 3 drives the pressure rod 11 to move downward, and the bottom end of the pressure rod 11 abuts against the roller 10, achieving a braking effect.

[0028] A structure such as a battery (not shown in the figure) can be provided inside the support frame 2 to supply power to the first electric push rod 4 .

[0029] In order to increase the friction between the steering support plate 7 and the ground, an anti-sliding block 8 is fixedly connected to the lower surface of the steering support plate 7, and a plurality of anti-sliding blocks 8 are provided.

[0032] During specific use, before the lifting support platform device is used, the telescopic end of the second electric push rod 14 is controlled to extend, driving the block 15 to move toward the axis of the slide column 6, so that the block 15 is engaged with the corresponding slot 13, so that the cylinder 5 and the slide column 6 will not rotate relative to each other, thereby improving the stability of the lifting support platform device.

[0033] When turning around in a narrow space, the telescopic end of the second electric push rod 14 is controlled to be retracted, so that the block 15 is pulled out from the inside of the corresponding slot 13, and the cylinder 5 and the slide column 6 can rotate relative to each other. At this time, the telescopic end of the second electric push rod 14 can be controlled to continue to be retracted, and there is a certain gap between the roller 10 and the ground. Then the lifting support platform device is rotated, and the U-turn is performed by relying on the cooperation of the cylinder 5 and the slide column 6. The operation is convenient. After adjustment, the telescopic end of the second electric push rod 14 is extended, the roller 10 abuts the ground, the steering support plate 7 has a certain gap with the ground, and the pressure rod 11 is out of contact with the roller 10, which is convenient for movement.
