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
The present invention is a kind of rapid unpowered bearing lifting mechanism, belongs to the structure and the field shaping technique of product.
Background technology
The loading and unloading operation of aircraft external store, crucial index is consuming time.Determine 5 key factors that comprise consuming time: the one, quick travel, the 2nd, rapid lifting, the 3rd, contraposition is installed, the 4th, there be not peripheral the dependence, the 5th, personnel labor intensity and operation easier.
What generally adopt at present is power is provided and power is provided and carries out dipping and heaving by the Electronmotive Force that motor provides by screw thread by hydraulic pressure.Long by the time that hydraulic pressure provides power to have force pump to provide the pressure hand-power to shake.The system architecture complexity need be to the cleaning and the pipeline handling labor of oil circuit.The screw thread lifting time is long especially, and personnel require many.The motor lifting needs the external energy or adopts storage battery that power is provided, and the external energy has increased the range of use restriction to equipment, adopts storage battery to increase the work capacity of battery maintenance.
Summary of the invention
The shortcoming that the present invention exists at above-mentioned existing apparatus just and design a kind of rapid unpowered bearing lifting mechanism is provided, its objective is provide a kind of need not propulsion source, non-traditional pneumatic or hydraulic actuator, can the fast lifting weight pure mechanical device.This mechanism form is simple, cheap, environmental protection, need not special maintenance, can be widely used in different weights, different adjustable height, have the operation of complete operation requirement in the short time.
The objective of the invention is to realize by following measure:
This kind rapid unpowered bearing lifting mechanism, comprise material bearing platform, the scissors lifting arm, the chassis, it is characterized in that: an end of the operating bar of pressurized strut is connected the rotating shaft connection by pressurized strut for the point of crossing of power attaching parts and scissors lifting arm bottom, pressurized strut is connected with operating bar by connecting pin for the power attaching parts, pressurized strut inside is provided with compression spring and is sleeved on the operating bar, make operating bar in the pressurized strut cylindrical shell before, back stroke has the elasticity playback, pressurized strut is connected with attachment lug by the pressurized strut rotating shaft, attachment lug is fixed on the pressurized strut bearing, and the pressurized strut bearing is fixed on the chassis.
Technical solution of the present invention adopts elastic potential energy, gravitional force switching mechanism, shortens once more the crucial requirement of attack time at aircraft, with realize plug-in thing fast, accurately loading and unloading.
This mechanism is the variation that causes the elastic energy of spring by the potential variation of the weight of weight in lifting process, reaches the gravity of weight in lifting and the Spring balanced of spring.Because in state of equilibrium, so weight can stop in the adjustable height variation range arbitrarily.When needs lifting weight, can be with minimum external force, comprise with manpower weight is promoted in certain range or descending.

Fig. 5 is the birds-eye view of Fig. 1
The specific embodiment
Below with reference to drawings and Examples technical solution of the present invention is further described:
Shown in accompanying drawing 1~2, this kind rapid unpowered bearing lifting mechanism, comprise material bearing platform 1, two groups of scissors lifting arms 2, chassis 3, it is characterized in that: an end of the operating bar 7 of two pressurized struts 6 is connected rotating shaft 12 connections by pressurized strut for the point of crossing of power attaching parts 11 and two groups of scissors lifting arm 2 bottoms, pressurized strut is connected with operating bar 7 by connecting pin 13 for power attaching parts 11, pressurized strut is for the framing member of power attaching parts 11 for band ears sheet or monaural sheet, mainly be with the spring force that the pressurized strut medi-spring provides make progress on component and the material bearing platform Loaded goods and carry out balance at the structural weight that is connected more than the rotating shaft, pressurized strut 6 inside are provided with compression spring 8 and are sleeved on the operating bar 7, make operating bar 7 in pressurized strut cylindrical shell 9 before, back stroke has the elasticity playback, pressurized strut 6 is connected with attachment lug 5 by pressurized strut rotating shaft 4, attachment lug 5 is fixed on the pressurized strut bearing 10, and pressurized strut bearing 10 is fixed on the chassis 3.
Adopt this mechanism, in conjunction with wheel, car body low-resistance translation technology, plug-in thing holder locking device, the plug-in thing that constitutes the aircraft different size is installed car.Adopt this mechanism, can design the serial locomotive work platform of stepless, degree of uprising, different size.
This mechanism in use, through design calculation, the spring force that the pressurized strut medi-spring is provided make progress component Loaded goods on platform with the flat-bed lifting process in, the weight of Loaded goods and the structural weight that is connected more than the rotating shaft are in state of equilibrium all the time.In the case, just can realize the fast lifting of Loaded goods at no exterior power or the external propulsion source hand-power of only choosing.
It is quick that mechanism of the present invention has realized that compared with prior art people's operation can be finished store Combinations Mobile, rapidly lifting, the installation contraposition is accurate, need not power, greatly reduces personnel labor intensity And operation easier.
