Embodiment Construction

[0011] The technical scheme of the present invention will be described in further detail below in conjunction with accompanying drawing and embodiment:

[0012] See attached Figure 1~2 As shown, this fast non-powered load-bearing lifting mechanism includes an object-bearing platform 1, two sets of scissor lifting arms 2, and a chassis 3. It is characterized in that: one end of the actuating rod 7 of the two actuating cylinders 6 passes through the actuating cylinder The power supply connector 11 is connected with the connection shaft 12 at the cross point of the two groups of scissor lift arms 2 bottoms, the power supply connector 11 of the actuator is connected with the actuating rod 7 through the connecting pin 13, and the power supply connector 11 of the actuator is Structural parts with double lugs or single lugs are mainly to balance the upward component of the spring force provided by the spring in the actuator with the load on the loading platform and the structural we...

Abstract

The invention relates to a quick unpowered load-bearing lifting mechanism. The lifting mechanism comprises a bearing platform, a shear lifting arm and a chassis, wherein one end of an actuating rod of an actuating drum is connected with a connection rotary shaft of a cross point at the lower part of the shear lifting arm through an actuating drum force-feed connecting piece; the actuating drum force-feed connecting piece is connected with the actuating rod through a connecting pin; and the inside of the actuating drum is provided with a compression spring which is sleeved on the actuating rod so as to ensure that the front and back strokes of the actuating rod have elastic restore inside an actuating drum body. The quick unpowered load-bearing lifting mechanism realizes balance between the gravity of a lifting heavy object and the elasticity of the spring by means of elastic energy change in the spring caused by the potential energy change in the heavy object during lifting; because the heavy object is in a balanced state, the heavy object can be stopped within any variation range of lifting height; therefore, when the heavy object needs to be lifted, just a tiny outside force (including manpower) can lift or drop the heavy object within a certain lifting range.

Description

technical field [0001] The invention is a fast non-powered load-bearing lifting mechanism, which belongs to the technical field of product structure and molding. Background technique [0002] The key indicator of loading and unloading of aircraft external stores is time-consuming. There are five important factors in determining the time-consuming: first, fast movement, second, rapid lifting, third, installation alignment, fourth, no external dependence, and fifth, labor intensity and difficulty of operation. [0003] What generally adopt at present is to provide power by hydraulic pressure and provide power by thread and carry out lifting movement by the electric power that motor provides. It is powered by hydraulic pressure and has a hand pump to provide pressure for a long time to shake manually. The structure of the system is complex, and oil circuit cleaning and pipeline maintenance are required. The thread lifting time is particularly long and requires many personnel...
