It breaks down, controller carries out maintenance down in time, further increases the robustness of the application.
The present embodiment is it is further preferred that reel 6 is set to the left side of the upper end of mounting plate 4, the hinged end setting of swing rod 9
In the lower section of reel 6, the free end of swing rod 9 is located at the right side of reel 6, and the lowermost that balance wheel 10 is arranged in measurement wheel 7 is swung
The left side of extreme position.Above-mentioned wheel group further includes the directive wheel 20 that the lower-left end of the trailing flank of mounting plate 4 is arranged in, wirerope
After 3 first pass through directive wheel 20, then successively by balance wheel 10 and measurement wheel 7.
The present embodiment is it is further preferred that be provided with limit plate 12 on swing rod 9, the left end of limit plate 12 and the hinge of swing rod 9
It is hinged to connect end, is provided with tension spring 13 between the right end and mounting plate 4 of limit plate 12, the right end of limit plate 12 is provided with locating slot
14, positioning column 15 is provided on swing rod 9, positioning column 15 is located in locating slot 14 and can move in locating slot 14.
The present embodiment is it is further preferred that the trailing flank of mounting plate 4 is respectively arranged with upper block in the two sides up and down of swing rod 9
Block 16 and lower stop block 17.
Positioning column 15 in the present embodiment on swing rod 9 and the locating slot 14 on limit plate 12 cooperate, make swing rod 9 by with again
Tension spring 13 shared of the opposite power of the pulling force of hammer by support spring 11 and limit plate 12, i.e. drawing of the swing rod 9 in balance weight 2
Two-man act applied force is used when power, reduces the working strength of support spring 11, and two-man act applied force, additionally it is possible to eliminate spring
Resonance, increase the service life of the present embodiment.Secondly, limit plate 12 is kept not when 2 weightlessness of weight causes swing rod 9 to move
Dynamic, when 2 state of weightlessness of weight terminates, weight 2 is in uphill process, and swing rod 9 is swung rapidly, when the positioning column 15 on swing rod 9 supports
When contacting the lower wall of locating slot 14 of limit plate 12, swing rod 9 can be made quickly to be restored to equilibrium state, guarantee that weight 2 is steady
Rising.
Swing rod in the present embodiment is there are four equilbrium position, and first equilbrium position is as shown in Fig. 2, when weight 2 is being shunk
During decentralization, swing rod 9 is under the action of 2 gravity of weight, limit plate 12, tension spring 13 and support spring 11 in balance
Position, limit plate 12 pass through the pressure that positioning column 15 applies in the pulling force and 16 resistance of upper stop block and swing rod 9 of tension spring 13
The lower state motionless in balance of effect, and the upper end of limit plate 12 is contradicted in the lower end of upper stop block 16.Positioning on swing rod 9
Column 15 is contradicted in the lower end of locating slot 14.
Second equilbrium position of swing rod 9 is as shown in figure 3, when weight 2 rises to the position on vertex, and swing rod 9 is in weight 2
The power that the power and support spring 11 that gravity, the block power of 1 lower end surface of cabinet applied to weight 2, tension spring 13 apply apply
The lower position in balance of effect, at this point, because swing rod 9 receives the effect for the power that 1 lower end surface of cabinet applies indirectly again, swing rod
The position of 9 free end can be slightly below the position of the above-mentioned swing rod 9 during 2 folding and unfolding of weight；Limit plate 12 is in tension spring 13
In equilbrium position under the action of the pressure that pulling force and swing rod 9 are applied by positioning column 15 because limit plate 12 simultaneously also by
The effect for the power that cabinet 1 lower end surface applies indirectly, therefore swing rod 9 passes through positioning column 15 when weight 2 rises to vertex position
The pressure of application is greater than swing rod 9 of the above-mentioned weight 2 during folding and unfolding and passes through the pressure that positioning column 15 applies, and limit plate 12 is equipped with
The free end of locating slot 14 is slightly below the lower end of upper stop block 16.
As shown in figure 4, when weight 2 is buried, wirerope 3 is downward to balance wheel 10 for the third equilbrium position of swing rod 9
Pulling force increases, and pulls downward on the free end of swing rod 9 always, swings to conflict until lower stop block 17 until swing rod 9, swing rod 9
It is kept out by lower stop block 17, reaches an equilbrium position, limit plate 12 is pulled down by swing rod 9 simultaneously, drawing of the limit plate 12 in weight 2
Reach equilbrium position under the action of the pulling force of power and tension spring 13.
4th equilbrium position of swing rod 9 is as shown in figure 5, when wirerope 3 is broken, pulling force of the balance wheel 10 by weight 2
Moment reduces, and swing rod 9 is swung up under the active force of support spring 11, and swing rod 9 is swung up conflict to upper stop block 16
Balance is kept when lower end, limit plate 12 contradicts under the active force of tension spring 13 and upper stop block 16 in the lower section of upper stop block 16
Keep balance.
The present embodiment is it is further preferred that above-mentioned sensor is Hall sensor, because Hall sensor is quick to magnetic field
Sense, structure is simple, small in size, frequency response is wide, output voltage variation greatly and long service life.It is easy to implement automation electric signal
Generation and transmission, make the application realize automation control, Hall sensor includes the magnet that the free end of swing rod 9 is arranged in
18, and the hall circuitboard 19 being arranged on the leading flank of mounting plate 4, it is arranged for incuding swing rod 9 on hall circuitboard 19

State is stablized and is quickly restored to such as figure to uphill process, block cooperation of the swing rod 9 between positioning column 15 and limit plate 12 is stablized
The equilbrium position of the swing rod 9 during folding and unfolding of weight 2 shown in 2, the magnet 18 on swing rod 9 incude Hall semiconductor chip 6- again
5, the power information that weight 2 moves is transferred to controller 5, controller 5 monitors the movement of weight 2；When weight 2 rises to vertex
When, since the lower end surface of cabinet 1 is applied with a block power to weight 2, make the increase subject to downward force of swing rod 9, make swing rod 9 to
Lower swing, an electric signal is generated when the magnet 18 on swing rod 9 senses Hall semiconductor chip 6-6, and hall circuitboard 19 will
To controller 5, controller 5 receives the electric signal and judges that weight has had reached vertex position, controller 5 electric signal transmission
It controls motor 8 to stop, swing rod 9 has reached equilbrium position as shown in Figure 3 again, and weight 2 has had increased to vertex at this time, complete
At a detection process, waiting detects next time.When occurring the case where weight 2 is buried in detection process, 2 stress of weight at this time
It is larger, drive swing rod 9 significantly to lower swing, when the magnet 18 on swing rod 9 senses Hall semiconductor chip 6-7, Hall
By the electric signal transmission to controller 5, controller 5 receives the signal and judges that weight 2 receives abnormal power circuit board 19,
Controller 5 controls the present embodiment maintenance down.When occurring the case where fracture of wirerope 3 in detection process, since wirerope 3 is disconnected
If splitting, 9 moment of swing rod loses the power of the application of weight 2, under the active force of tension spring 13 and support spring 11 significantly upwards
It swings, when the magnet 18 on swing rod 9 senses Hall semiconductor chip 6-1, generates an electric signal, hall circuitboard 19 should
