Problems solved by technology
With the further development of aerial work platforms, the working space is becoming more and more large, so it is necessary to have a movable platform that can be extended in both directions, but if the movable platform is extended in both directions, when the other side is extended without sliding blocks It will lead to instability of the platform, and even the danger of rollover

A scissor component of the bidirectional scissor lifting device of the aerial working platform consists of outer scissor components and inner scissor components, wherein a connecting rod is arranged between two sets of scissor components; the lower ends of a bottom outer scissor component and a bottom inner scissor component of the scissor device are respectively provided with a lower sliding block in an articulating way, lower sliding rails are arrangedon a machine body, the lower sliding blocks is arranged on the lower sliding rails, the middle part of the bottom inner scissor component is provided with a first articulated rod in an articulating way, and the lower end of the first articulated rod is articulated with the machine body; the upper ends of a top outer scissor component and a top inner scissor component of the scissor device are respectively provided with an upper sliding block in an articulating way, and upper sliding rails are arranged on the bottom of the working platform; the upper sliding blocks are arranged on the upper sliding rails, and the middle part of the top inner scissor component is provided with a second articulated rod in a articulating way, and the upper end of the second articulated rod is articulated with the bottom of the platform. The bidirectional scissor lifting device has the characteristics of simple structure and good overall stability.
Description
technical field [0001] The invention relates to an aerial work platform, in particular to a bidirectional scissor lifting device for an aerial work platform. Background technique [0002] The existing aerial work platform includes a fuselage, a walking device, a lifting device and a working platform. The working platform is arranged above the lifting device; Barrel lifting device. The scissor lifting device is such as the scissor lifting device of the aerial work platform disclosed in the Chinese utility model patent (application number: 200720114879.8, the application date: 2007-09-14). The scissor lifting device includes 2 sets of cross structures and drives 2 A set of oil cylinders with a cross structure, two sets of cross structures are respectively composed of several connecting rods hinged, and the two sets of cross structures are connected by connecting rods. One arm of the cross structure is hingedly arranged on the fuselage, and the other arm is movably arranged o...
