Problems solved by technology
[0005] The technical problem solved by the present invention is to provide a new type of electromagnetic-screw cooperatively driven scissors for the problems of the existing elevating table-type aerial work devices, such as the large size, heavy weight, small lifting height, and small bearing capacity of the lifting mechanism. The fork lifting device can meet the needs of high-altitude operations such as large load, high lift, small size, and small weight.

The invention discloses an electromagnetic-screw collaborative drive shear fork lifting device. The device comprises a bottom platform, a polygonal shear fork module, a screw drive mechanism and a supporting platform; the supporting platform and the bottom platform are arranged in a lifting supporting manner through the polygonal shear fork module, the polygonal shear fork module comprises a shearfork mechanism and an electromagnetic drive mechanism, the screw drive mechanism is assembled on the bottom platform in a sliding manner, the screw drive mechanism and an electromagnetic drive mechanism drive the shear fork mechanism in the vertical direction and the transverse direction, the electromagnetic drive mechanism is arranged between transverse supporting frameworks of the polygonal shear fork module, the bearing capacity and transverse load resisting capacity of the shear fork mechanism are increased, the screw drive mechanism drives multiple screws to rotate at the same time through a motor, and the phenomenon that when the shear fork mechanism drives the initial work, dead points exist in the transverse direction is avoided. The device has the beneficial effects of being large in bearing capacity, large in lifting height, large in transverse load resisting capacity, small in size, small in weight and the like, and the needs of bearing, height, size, weight and the like inactual application are met.
Description
technical field [0001] The invention belongs to the technical field of lifting equipment, and in particular relates to an electromagnetic-screw-screw cooperatively driven scissor lifting device with large bearing capacity and high lifting height. Background technique [0002] Modern large-scale factory equipment maintenance, high-altitude infrastructure construction, high-altitude rescue and other occasions often require a large number of high-altitude operations, and most of them are currently done manually. There are a large number of safety accidents caused by high-altitude operations every year around the world. Therefore, high-altitude operations are classified as for high-risk industries. The current high-altitude working devices mainly have two working modes: climbing type and lifting table type. Among them, the climbing type working mode mostly adopts automatic equipment, which requires no complicated obstacles in the environment and good magnetic permeability of env...
