Lifting platform

Abstract

The invention discloses a lifting platform which comprises a lower platform, an upper platform, and a left L-shaped supporting rod and a right L-shaped supporting rod which are arranged between the upper platform and the lower platform, wherein two rod bodies of the left L-shaped supporting rod and the right L-shaped supporting rod are connected with each other through a rotating shaft; a concave cavity is formed in the center of the bottom surface of the upper platform; the lifting platform is further provided with a folding rod; a rotary retractable rod is arranged at the other end of the folding rod; limiting clamping blocks are arranged at two ends of the rotary retractable rod; one end of each limiting clamping block is connected to the position, close to the end point, on the rotary retractable rod through a pin shaft, and an n-shaped buckling slot is formed in the other end of each limiting clamping block; clamping convex blocks for clamping the n-shaped buckling slots are arranged on the two rod bodies of the left L-shaped supporting rod and the right L-shaped supporting rod; and clamping pressing blocks are arranged on the end surfaces of the rotary retractable rod. The lifting platform is simple in structure and convenient to operate; the stability and the reliability of use are guaranteed; furthermore, the folding rod can also achieve a middle part supporting effect, so that the steadiness of the upper platform can be effectively guaranteed; and the lifting platform is high in applicability and high in practicability.

Description

technical field [0001] The invention belongs to the technical field of lifting platforms, and in particular relates to a lifting platform. Background technique [0002] In equipment such as aerial work lifting platforms, a scissor lift mechanism is usually used to realize the lifting operation of the platform. The scissor lift mechanism is mainly composed of a platform, a bottom plate and a scissor bracket. The scissor bracket is composed of two connecting rods and connected in the center of the connecting rod. The rotating shaft is composed of a horizontal chute on the same side of the platform and the bottom plate. One end of the connecting rod is connected with the platform or the bottom plate through a pin shaft, and the other end is movably set in the horizontal chute through a slider. When lifting, the scissors bracket is lifted by moving the slider. Although it can realize the lifting operation, its use stability is poor, and it is mainly pressed by the two connecting...

[0002] In equipment such as aerial work lifting platforms, a scissor lift mechanism is usually used to realize the lifting operation of the platform. The scissor lift mechanism is mainly composed of a platform, a bottom plate and a scissor bracket. The scissor bracket is composed of two connecting rods and connected in the center of the connecting rod. The rotating shaft is composed of a horizontal chute on the same side of the platform and the bottom plate. One end of the connecting rod is connected with the platform or the bottom plate through a pin shaft, and the other end is movably set in the horizontal chute through a slider. When lifting, the scissors bracket is lifted by moving the slider. Although it can realize the lifting operation, its use stability is poor, and it is mainly pressed by the two connecting rods of the scissors bracket without corresponding restrictions. Position fixed structure, so it is easy to slip or automatically reset in actual use, which affects the stability and reliability of lifting, and the applicability and practicability are limited
