Crank arm type elevator with high structural strength

Abstract

The invention discloses a crank arm type elevator with high structural strength, which comprises a chassis, a sliding groove, an operation platform, a supporting frame and a through hole, wherein a rotating table is rotationally connected to the upper side of the chassis, a first motor connected with the rotating table is fixedly mounted in the chassis, and a stand column is fixed to the top of the rotating table. The crank arm type elevator with the high structural strength is provided with first gears and second gears, the number of first crank arms, the number of second crank arms and the number of third crank arms are all two, and the two first crank arms, the two second crank arms and the two third crank arms are connected in a matched and meshed mode through the first gears and the second gears; when a hydraulic cylinder pushes a certain first crank arm or a certain second crank arm or a certain third crank arm to rotate, the corresponding first crank arm or the corresponding second crank arm or the corresponding third crank arm is pushed to rotate by the same angle through meshing between the first gear and the second gear; through the structure, the structural strength of the crank arm type elevator is improved, and the crank arm type elevator is more practical in use.

Description

technical field [0001] The invention relates to the technical field of crank-arm lifts, in particular to a crank-arm lift with high structural strength. Background technique [0002] Articulated boom lifts are lifting equipment used for high-altitude operations, and are more suitable for narrow spaces than traditional lifting equipment. [0003] The existing articulating arm lifts are usually not equipped with a self-locking structure, and only rely on the hydraulic system to continuously support the arm, resulting in a large burden on the hydraulic system. Once the hydraulic system fails, accidents are likely to occur, and there are certain safety hazards in use. Now Some crank arm lifts are supported by only a single crank arm, resulting in low overall structural strength of the crank arm lift, which cannot lift heavy equipment for operation, and the existing crank arm lifts are usually not equipped with hoisting devices. As a result, the material carried by the operator ...

Problems solved by technology

[0004] The object of the present invention is to provide a crank-arm lift with high structural strength to solve the problem that the existing crank-arm lifts proposed in the above-mentioned background technology are usually not provided with a self-locking structure, and only rely on the hydraulic system to continuously support the crank arm, resulting in The burden on the hydraulic system is large. Once the hydraulic system fails, accidents are likely to occur, and there are certain safety hazards in use. The existing crank arm lifts are only supported by a single crank arm, resulting in insufficient overall structural strength of the crank arm lift. High, it is impossible to lift heavy equipment for operation, and the existing articulating arm lifts are usually not equipped with hoisting devices, resulting in limited materials carried by operators in one lift. When transporting a large amount of materials, reciprocating lifting is required, which prolongs the working time. The problem of not being convenient enough to use
