The specific embodiment
Fig. 1 ~ 5th, most preferred embodiment of the present invention, the present invention will be further described below in conjunction with accompanying drawing 1 ~ 5.
With reference to accompanying drawing 1-4: should be based on the large load Quick-disassembling device of controlled in wireless, comprise the hoisting device for the hook block goods, hoisting device one end is hook 1, the other end is and hook 1 pipe link that connects as one 5, hoisting device is rotatably installed in the housing that is comprised of supported on both sides plate 3 by the first set pin 2, and links up with 1 and stretch out housing.Stay bearing plate 3 one ends of both sides are serially connected by the first set pin 2, and the other end is serially connected by anchor shaft 8, and anchor shaft 8 covers have axle sleeve 9, the first set pins 2 that supported on both sides plate 3 separated and locate to be arranged near an end of linking up with 1.Hoisting device one side is installed the lever 4 that pipe link 5 can be locked to prevent the hoisting device rotation, lever 4 fixed ends are fixed in supported on both sides plate 3 by the second set pin 10, movable end is installed and can be limited the electric pushrod device that lever 4 rotates, and the second set pin 10 is arranged on lever 4 and the contacted end of pipe link 5.
The electric pushrod device comprises electric pushrod 6 and the wireless receiving module 7 of round bar shape, electric pushrod 6 activities are through supported on both sides plate 3, the electric pushrod 6 that stretches out is pressed in the movable end of lever 4, lever 4 movable end termination circumference are set with antifriction-bearing box 11, electric pushrod 6 and antifriction-bearing box 11 outer wall movable contacts.Antifriction-bearing box 11 has reduced electric pushrod 6 friction force, electric pushrod 6 is slided more smooth.Wireless receiving module 7 is arranged on stay bearing plate 3 outsides and passes through connection with electric pushrod 6.Electric pushrod 6 and wireless receiving module 7 all adopt DC power supply, after wireless receiving module 7 receives enable signal, can make electric pushrod 6 get electric and telescopic slide.
In above-described embodiment, electric pushrod 6 directly penetrates in the circular hole of supported on both sides plate 3, electric pushrod 6 is realized free-running fit with the circular hole inner ring, also can be fixedly mounted with respectively a bearing in the circular hole of supported on both sides plate 3, outside race and circular hole inner ring interference fit, electric pushrod 6 and bearing inner ring free-running fit, bearing width equates with the thickness of supported on both sides plate 3.
Should adopt secondary load to reduce transferring structure based on the large load Quick-disassembling device of controlled in wireless; make the pressure that finally is applied to electric pushrod 6 less according to principle of moment balance; only need very little pulling force just can realize fast discharging; realized the fast discharging of the large load of any direction; simultaneously the stay bearing plate 3 of both sides has not only limited the degree of freedom of hoisting device, lever 4; make them can only be at a rotation with in surface; improved the stability of Quick-disassembling device; and increased protection intensity to whole mechanism, improved the reliability of this device.
With reference to accompanying drawing 5, this principle of work based on the large load Quick-disassembling device of controlled in wireless is as follows:
When the hook 1 of hoisting device was subject to the large load of any direction, whole device was tightened up, and hook 1 has the trend of rotating around the first set pin 2 under the directed force F effect.According to principle of moment balance, due to the brachium difference on pipe link 5 both sides, pass to the pressure N of lever 4
1Less, realized that the one-level that load is transmitted reduces.Lever 4 is at pressure N
1Under effect, the trend of rotating around the second set pin 10 is arranged, lever 4 movable end termination contacts are on electric pushrod 6, if application force is N, equally according to principle of moment balance, two point of actions are also different to the distance of the second set pin 10, and the load N that imposes on electric pushrod 6 further reduces, and realized that the load secondary reduces.After reducing through the load secondary, the pressure N that act on electric pushrod 6 this moment is very little, add and antifriction-bearing box 11 between friction of rolling, electric pushrod 6 just can be skidded off by very little pulling force.Electric pushrod 6 and wireless receiving module 7 all adopt the DC power supply by 24V, after wireless receiving module 7 receives enable signal, electric pushrod 6 gets electric slip on antifriction-bearing box 11 under motor-driven, utilize very little pulling force just electric pushrod 6 can be skidded off from stay bearing plate 3, realized the fast discharging of the large load of any direction.When skidding off moment from stay bearing plate 3, realizes electric pushrod 6 fast discharging of large load.
Pressure N much smaller than the theoretical proof of external load F is: be F if be applied to the value of thrust of hook 1, according to principle of moment balance, the pressure N that is applied on electric pushrod 6 is:
,
Wherein:
Be angle between pipe link 5 and lever 4,
Less, can think that N1 is perpendicular to pipe link 5 and lever 4; Much smaller than l2, l3 length can get according to following formula much smaller than l4 due to l1 length, and the pressure N that acts on electric pushrod 6 links up with 1 value of thrust F much smaller than being applied to.
The above is only preferred embodiment of the present invention, is not to be the present invention to be done the restriction of other form, and any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solution of the present invention content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belongs to the protection domain of technical solution of the present invention according to technical spirit of the present invention.
