The present invention operation principle be：When lifter plate carries out normal elevating movement, due to the first compliant section and second
Compliant section remains parallel with the lifting direction of lifter plate during lifting, therefore the incrementss of the first compliant section or subtracts
Equal with the decrement or incrementss of the second compliant section on a small quantity, both total lengths keep constant, and middle transition section is rising vertically
Keep constant with the contact each point of deflecting wheel group during drop, therefore the total length of flexible hanging member keeps constant.So, rise
When drop plate is normally lifted, dynamic equilibrium protection mechanism can normally follow lifter plate to carry out elevating movement together without sending out
Protective effect is waved, without prejudice to the normal lifting of lifter plate.
When the elevating chain on lifter plate is broken, flexible hanging member corresponding with the elevating chain that this is broken
Elevating chain can be replaced, pulling force is applied to the lifter plate of the side, prevents its descending motion.Specifically, when wherein one lifting
After chain breakage, lifter plate under gravity can towards fracture chain side tilt down, the banking motion according to
Rectangular coordinate system in space can be analyzed to three vertical motion of Z axis, the horizontal movement of X-axis and the horizontal movement of Y direction sides
To componental movement.
Wherein, the vertical motion of Z axis is motion when lifter plate normally lifts, therefore the motion can be normally carried out.
And the horizontal movement of X-axis will produce a skew in the horizontal direction so that the first compliant section is changed into tiltedly from vertical state
Straight state, under the two states, the first compliant section respectively constitutes the right-angle side and hypotenuse of right angled triangle, is more than according to hypotenuse
The principle of right-angle side understands that the length of first compliant section under tilted and direct state should be more than the length under vertical state, i.e.,
It is required that the length of the first compliant section will increase；Similarly, the horizontal movement also can cause the second compliant section to be changed into from vertical state
Tilted and direct state, therefore it is required that the second compliant section will also increase；And middle transition section in horizontal movement due to caused by contact point
Change is very little, can be ignored, it can be seen that, the horizontal movement of X-axis can cause flexible hanging member to increase, this
The fact that immobilized with flexible hanging member total length contradicts, therefore flexible hanging member will prevent entering for X-direction motion
OK.Similarly, the horizontal movement of Y-axis can also cause the length of flexible hanging member to increase, therefore flexible hanging member will be to preventing Y-axis side
To the progress of motion.
Therefore, flexible hanging member can prevent the progress of two componental movements of lifter plate X-direction and Y direction all the time, when
The progress of total motion synthesized by componental movement is so also prevented, so, when lifter plate tilts down motion, flexible hanging member
Pulling force can be applied to it, prevent its inclination, prevent the lifting thing of lifter plate from gliding.
The present invention has following beneficial effect compared with prior art：
1st, the device can either be protected during elevating movement to the lifter plate after generation chain rupture, and and can is enough to place
Protected in the lifter plate of inactive state, therefore protecting effect is good.
2nd, the dynamic when device only needs the mutual cooperation between flexible hanging member and deflecting wheel group with regard to enough completion liftings
Protection, it is not necessary to the participations of other components and the braking of extra power (documents in such as background technology need clutch,
Insure rope drum etc.), therefore simple in construction, easy for installation and cost is low, can be promoted the use of on a large scale.
3rd, when elevating chain is broken, due to flexible hanging member limit lifter plate can only carry out vertical motion characteristic make
Obtaining the dynamic protection mechanism can act immediately, and the very first time prevents lifter plate from tilting, so that being not in during chain breakage
Obvious pause is rocked, therefore dynamic protection effect is good.
4th, when elevating chain fracture occurs in lifting process, the device can also continue to complete the lifting fortune of lifter plate
It is dynamic, realize provisional operation.Specifically, during chain rupture, flexible hanging member can completely instead of the fracture elevating chain with it is other
Elevating chain cooperating so that drop lifter plate is moved downward and can normally continued.

Rear sprocket wheel 2-22 in state balanced protection mechanism 2-B2 is also that sprocket wheel 2-22 is same respectively after sprocket wheel 2-22 and two after two, two
Axle links to form two double chain wheels, and one of double chain wheel positioned at the side of lifter plate 3 is corresponding with the opposite side of lifter plate 3 one
Double chain wheel coaxial linkage is set.It is soft to first in rear end dynamic equilibrium protection mechanism 2-B2 by sprocket wheel 2-22 after setting two
Property section 2-11 and the second compliant section 2-12 carry out transition, be deflecting wheel group 2-2 middle sprocket minimum numbers scheme, advantageously reduce
Resistance so that the motion of lifter plate 3 is more smooth.
Referring to Fig. 7, positioned at the same side of lifter plate 3 two double chain wheels center vertically and horizontally mutually
Stagger, and close to rear sprocket wheel 2-22 a double chain wheel under, for another double chain wheel upper, one close to rear sprocket wheel 2-22 is double
Sprocket wheel is located at same level with rear sprocket wheel 2-22 in the vertical directions.By allowing two double chain wheels in vertical direction and level side
To mutually staggering, it is easy to chain to bypass the double chain wheel, by allowing a double chain wheel and rear sprocket wheel 2-22 close to rear sprocket wheel 2-22
In the vertical direction is located at same level so that the chain between them is horizontal-extending, makes the stress of lifter plate 3 more equal
Weighing apparatus.
Referring to Fig. 8, the frame includes front column 4-2, rear column 4-3 and crossbeam 4-1, and the crossbeam 4-1 is arranged on
Front column 4-2, rear column 4-3 top；The upper end of the flexible hanging member 2-1 is fixed on crossbeam 4-1 by upper connector 4-4
On, lower end is connected to rear column 4-3 bottom by lower connector 4-5, and the upper connector 4-4 and lower connector 4-5 are
Screw rod, one end of the screw rod are connected with flexible hanging member 2-1, and the other end is fixed on rear column 4-3 or crossbeam 4-1 by nut
On.Flexible hanging member 2-1 being reliably connected in frame so can be achieved.
Referring to Fig. 1-Fig. 5, operation principle of the invention is：When lifter plate 3 carries out normal elevating movement, due to first
Compliant section 2-11 and the second compliant section 2-12 remains parallel with the lifting direction of lifter plate 3 during lifting, therefore
First compliant section 2-11 incrementss 2-111 or decrement is equal with the second compliant section 2-12 decrement 2-121 or incrementss,
Both total lengths keep constant, and middle transition section 2-13 is equal with deflecting wheel group 2-2 contact each point during vertical lifting
Keep constant, therefore flexible hanging member 2-1 total length keeps constant.So, when lifter plate 3 is normally lifted, dynamic is flat
Weighing apparatus protection mechanism 2 can normally follow lifter plate 3 to carry out elevating movement together without playing protective effect, without prejudice to lifter plate
3 normal lifting.
Referring to Fig. 2, when the elevating chain 1-1 on lifter plate 3 is broken, the elevating chain 1-1 that is broken with this
Corresponding flexible hanging member 2-1 can replace elevating chain 1-1, apply pulling force to the lifter plate 3 of the side, prevent it from declining fortune
It is dynamic.Specifically, after a wherein elevating chain 1-1 fracture, lifter plate 3 under gravity can be towards fracture chain place
One is sloped downwardly, and the banking motion can be analyzed to the horizontal movement of the vertical motion of Z axis, X-axis according to rectangular coordinate system in space
And the componental movement in three directions of horizontal movement of Y direction.
Referring to Fig. 4 and Fig. 5, the vertical motion of Z axis is motion when lifter plate 3 normally lifts, therefore the motion can
It is normally carried out.And the horizontal movement of X-axis will produce a skew in the horizontal direction so that the first compliant section 2-11 is from vertical
State 2-11 is changed into tilted and direct state 2-11 ', and under the two states, the first compliant section 2-11 respectively constitutes right angled triangle
Right-angle side and hypotenuse, it can be seen from hypotenuse is more than the principle of right-angle side, the length of first compliant section under tilted and direct state 2-11 '
The length under vertical state 2-11 should be more than, that is, requiring the first compliant section 2-11 length will increase；Similarly, the level is transported
It is dynamic also to cause the second compliant section 2-12 to be changed into tilted and direct state 2-12 ' from vertical state 2-12, therefore it is required that the second compliant section
2-12 will also increase；And middle transition section 2-13 in horizontal movement because change caused by contact point is very little,
It can be ignored, it can be seen that, the horizontal movement of X-axis can cause flexible hanging member 2-1 to increase, this and flexible hanging member 2-1
The fact that total length immobilizes contradicts, therefore flexible hanging member 2-1 will prevent the progress that X-direction is moved.Similarly, Y
The horizontal movement of axle can also cause flexible hanging member 2-1 length to increase, therefore flexible hanging member 2-1 will be to preventing Y direction
The progress of motion.
Therefore, flexible hanging member 2-1 can prevent lifter plate 3 along two componental movements of X-direction and Y direction all the time
Carry out, also prevent the progress of total motion synthesized by componental movement certainly, it is so, soft when lifter plate 3 tilts down motion
Property suspender 2-1 can apply pulling force to it, prevent its inclination, prevent the automobile on lifter plate 3 from gliding.
