Description

Technical Field

[0001] The utility model relates to the technical field of lifting flat plates, in particular to an anti-tilt type steel platform device. Background Art

[0002] When the lifting platform is lifting goods vertically, if the load cannot maintain balance, it is easy to cause the platform to tip over. To solve this problem, the prior art has a notice number of CN219489520U, which discloses an anti-tilt lifting platform, including a fixed base, a moving wheel, a brake stepping motor, a lifting mechanism and an operating platform. The bottom outer surface of the fixed base is evenly spaced and provided with moving wheels, the top outer surface of the fixed base is fixedly installed with a lifting mechanism, and the top outer surface of the lifting mechanism is fixedly installed with an operating platform, and the fixed base is preset with an installation cavity inside. The anti-tilt lifting platform, when the device is used as a whole, controls the rotation of the limit rotating shaft as a whole, and cooperates with the meshing connection of the limit gear 1, the limit rack 1, the limit gear 2 and the limit rack 2, so that the limit rack 1 and the limit rack 2 are simultaneously unfolded to both sides, and at the same time drive multiple conflicting support seats to extend and conflict with the ground, so that the overall support area is expanded, thereby ensuring the overall use safety and preventing the overall tilting during use.
