Embodiment Construction

[0015] The following specific examples are only to explain the present invention, but not to limit the present invention. Those skilled in the art can make modifications without creative contribution to the present examples as needed after reading this specification, but as long as the rights of the present invention are used All claims are protected by patent law.

[0016] A scissor lifting assembly a of the present invention includes a scissor frame 3, a lifting mechanism 1 and a weighing mechanism 2. The scissors frame 3 is provided with a rotating connecting rod 4 transversely, and the rotating connecting rod 4 The scissor frame 3 can be rotated around its central axis relative to the scissor frame 3 , and the rotary link 4 and the scissor frame 3 are connected by a bearing to realize the rotation of the rotary link 4 . The lifting mechanism 1 adopts the form of an electric push rod 12 to avoid the use of a hydraulic system and achieve clean and efficient effects. Specific...

Abstract

The invention relates to the technical field of aerial work machinery, in particular to a scissor type aerial work platform and a scissor lifting assembly thereof, the scissor lifting assembly comprises a scissor frame, a lifting mechanism and a weighing mechanism, a rotary connecting rod is transversely arranged on the scissor frame in a penetrating mode, and the rotary connecting rod can rotate around the central axis of the rotary connecting rod; the hoisting mechanism comprises a driving base and a push rod extending out of the driving base; the lower end of the driving base is rotationally connected with the shear fork frame, and a rotary sleeve is fixed to the extending top end of the push rod and fixedly sleeves the periphery of the rotary connecting rod; the weighing mechanism is arranged on the rotary sleeve and the rotary connecting rod and can measure the bearing capacity of the rotary connecting rod. The weighing mechanism can measure the bearing capacity of the rotary connecting rod, a manufacturer determines that the maximum bearing capacity of one rotary connecting rod corresponds to the maximum bearing capacity of the shear fork frame, and the weighing mechanism can enable a user to see whether the actually-measured bearing capacity exceeds the specified maximum bearing capacity or not in a manner of externally connecting a display screen and the like. And safety accidents caused by overload are avoided.

Description

technical field [0001] The invention relates to the technical field of aerial work machinery and equipment, in particular to a scissor type aerial work platform and a scissor lift assembly. Background technique [0002] Aerial work platform (Aerial work platform) is a product that serves mobile aerial work such as aerial work, equipment installation, and maintenance in various industries. Aerial work platform related products mainly include: scissor type aerial work platform, vehicle-mounted aerial work platform, articulated arm type aerial work platform, self-propelled aerial work platform, aluminum alloy aerial work platform, cylinder-type aerial work platform six categories. The scissor-type aerial work platform generally includes a base, a wheel assembly is arranged at the bottom of the base, a lifting mechanism is arranged on the base, and a working platform is arranged on the lifting mechanism, and most of the lifting mechanisms are driven by hydraulic cylinders. The ...
