Description

Technical Field

[0001] This utility model relates to the field of lifting technology, specifically to an electric safety lifting platform for lifting goods. Background Technology

[0002] Scissor lifts are versatile aerial work platforms. Their scissor-type mechanical structure provides high stability after lifting, while their large working platform and high load capacity allow for a wider working range and suit multiple people working simultaneously. They make aerial work more efficient and safer. They are a versatile aerial work platform lifting device.

[0003] As disclosed in the patent announcement CN212687510U, a dual-drive lifting platform in the field of lifting platforms includes a base box and a cable. Support columns are fixedly connected to both sides of the top of the base box, and pulleys are movably connected to the top of the support columns via a rotating shaft. This utility model constructs a dual-drive lifting platform through the arrangement of the base box, cable, support columns, pulleys, lifting plate, lifting ring, motor, transmission shaft, take-up reel, electric telescopic rod, and support plate. The motor drives the transmission shaft to rotate, which in turn drives the take-up reel to rotate. The take-up reel can then tighten the cable, allowing the lifting plate to move up and down, forming a single-stage drive lifting platform. The electric telescopic rod then pushes the support plate to adjust its height. The cooperation of the two achieves the purpose of dual drive.

[0004] Although it solves the problem that single-stage elevator systems cannot reach higher heights while meeting a certain lifting stroke, thus affecting high-altitude assembly operations.

[0005] However, this does not solve the problems that existing elevators of this type are generally not conducive to the convenient lifting of goods, the inconvenience of adjusting the lifting position of goods, the inconvenience of adjusting the circumferential rotation position of goods by electric safety elevators, the inconvenience of limiting the goods during transportation, and the fact that goods are prone to deviating and falling during transportation, affecting safety.
