For the ease of understanding the utility model, in the following with reference to the drawings and specific embodiments, the utility model is carried out more detailed
Thin explanation.The preferred embodiment of the utility model is given in attached drawing.But the utility model can be with many different
Form is realized, however it is not limited to this specification described embodiment.On the contrary, purpose of providing these embodiments is makes to this
The understanding of the disclosure of utility model is more thorough and comprehensive.
The embodiment of weight dropper charge level indicator provided by the utility model, as shown in Figure 1, including cabinet 1, weight 2, connection weight
The wheel group of 2 wirerope 3, winding wire ropes 3 is provided with mounting plate 4 in cabinet 1, and the trailing flank of mounting plate 4 is arranged in wheel group,
Wheel group includes reel 6, directive wheel 5, measurement wheel 7, and the motor that driving reel 6 rotates, installation are provided on the leading flank of mounting plate 4
Balance mechanism is hingedly provided on the trailing flank of plate 4, balance mechanism includes swing rod 9, and one end of swing rod 9 is hinged on mounting plate 4,
The other end of swing rod 9 is free end and is provided with balance wheel 10, and swing rod 9 is placed in left-right direction, and balance mechanism further includes support force bullet
Spring 11, one end of support spring 11 are connected on mounting plate 4, and the other end is connected on swing rod 9, and reel 6 is set to mounting plate 4
The lower left of mounting plate 4 is arranged in upper left side, directive wheel 5, and balance wheel 10 is located at the lower right of reel 6, and the free end of swing rod 9 is located at
The right side of reel 6, measurement wheel 7 are located at the lower left of balance wheel 10 and on the right sides of directive wheel 5, and wirerope 3 is wrapped on reel 6,
And wirerope 3 by reel 6 down around directive wheel 5, balance wheel 10, then the lower-left by balance wheel 10 are bypassed by the upper right side of directive wheel 5
Side forms detour bending winding around measurement wheel 7, and wirerope is enable to be stretched between directive wheel 5, balance wheel 10 and measurement wheel 7.
Weight 2 is stretched out by the lower end of cabinet 1, is provided in cabinet 1 and is measured the first sensor for enclosing number for taking turns 7 for measuring, in cabinet 1
Be additionally provided with the second sensor for detecting 10 swing state of balance wheel, be provided with controller on mounting plate 4, first sensor and
Second sensor and controller communicate to connect.
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.Locating slot
14 lower end surface is balanced limit during 3 folding and unfolding of wirerope and in 3 complete retracted state of wirerope to swing rod 9,
The upper surface of locating slot 14 swings limit spacing to swing rod 9 under 2 state of weightlessness of weight.
The locating slot 14 being arranged on limit plate 12, positioning column 15 and locating slot 14 on swing rod 9 cooperate, make swing rod 9 by
The power opposite with the pulling force of weight 2 by 13 shared of tension spring of support spring 11 and limit plate, i.e., swing rod is in balance weight 2
Pulling force when use two-man act applied force, reduce the working strength of support spring 11, and two-man act applied force, additionally it is possible to eliminate
The resonance of spring increases the service life of the application.Secondly the limit plate 12 of setting causes swing rod 9 to move in 2 weightlessness of weight
When, which remains stationary, and when 2 state of weightlessness of weight terminates, in uphill process, swing rod 9 is swung rapidly weight 2, when
When positioning column 15 on swing rod 9 contradicts the lower wall for arriving the locating slot 14 of limit plate 12, swing rod 9 can be made quickly to be restored to balance
State guarantees that weight 2 smoothly rises.
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.
In use, when needing to detect the height of charge level, wirerope is put in the rotation of motor driven reel 6 to the present embodiment,
Weight 2 moves downward, since the wirerope 3 of connection weight 2 is around the balance wheel 10 on swing rod 9, wirerope 3 to swing rod 9 one to
Under tightening force, support spring 11 give 9 one upward power of swing rod, make swing rod 9 in 2 motion process of weight and weight 2 reach
In the state that a balance is motionless when to vertex.When weight 2 touches charge level, charge level gives weight 2 one upward power, makes
2 moment of weight forms weightless state, and the power mutually balanced being subject to originally on swing rod 9 at this time is destroyed, and weight 2 is applied to pendulum
Power moment on bar 9 reduces, and swing rod 9 can be swung under the active force of support spring 11, and swing rod 9 touches during swing
To second sensor, when second sensor senses that the variation of swing of the swing rod 9 because of 2 state of weightlessness of weight generates a telecommunications
Number, for second sensor by the electric signal transmission to controller, controller receives electric signal control motor reversal, drives weight 2
Rise back to the position on vertex.Primary detection is completed, the present embodiment can sensitively monitor the state of weightlessness of weight 2,
Timely control motor drives weight 2 to rise, and avoids weight 2 and is buried, and causes motor impaired.
The wirerope that the present embodiment is used to hang weight successively bypasses directive wheel 5, balance wheel 10 and measures wheel 7, and due to
Directive wheel 5, balance wheel 10 and measurement wheel 7 position, make wirerope 3 in detour bending winding, the normal test of weight 2 and rise
In the process, wirerope 3 is in tensioning state on directive wheel 5, balance wheel 10 and measurement wheel 7, makes the stable raising and lowering of weight 2.
When the moment that weight 2 is weightless suddenly, 3 moment of wirerope between balance wheel 10 and measurement wheel 7 is in relaxed state, keeps balance wheel 10 upward
Motion detection is to second sensor, at this point, quickly wirerope 3 is tightened in reversion to reel 6, wirerope 3 is under the active force of directive wheel 5
The movement of quick and stable guarantees that weight 2 is capable of the retracted state that rises into of quick and stable, and the application is in directive wheel 5 and pendulum
Under the action of wheel 10, weight 2 is made quick smoothly to enter propradation by state of weightlessness, has reduced the shaking of weight 2 to the greatest extent, made
The application movement is steady, and detection efficient is high.
The present embodiment is it is further preferred that above-mentioned second sensor is Hall sensor, because Hall sensor is to magnetic
Field sensitive, structure are simple, small in size, frequency response is wide, output voltage variation greatly and long service life.It is easy to implement automation electricity
The generation and transmission of signal make the application realize automation control, and Hall sensor includes the magnetic that the free end of swing rod 9 is arranged in
Iron 18, and the hall circuitboard 19 being arranged on the leading flank of mounting plate 4, setting detection magnet 18 on hall circuitboard 19
The Hall semiconductor chip set.
The present embodiment further can also understand in time weight 2 according to the swing position that Hall sensor perceives swing rod 9
Whether break down, if weight 2 breaks down, controller carries out maintenance down in time, further increases the present embodiment
Robustness.
The present embodiment is provided with side block blocks 21 around the side of wirerope it is further preferred that measurement takes turns 7, further prevents steel
Cord takes off wheel under 2 state of weightlessness of weight.
The present embodiment is crossed on rope pipe 22 and is provided with observation it is further preferred that the lower end of cabinet 1 was installed with rope pipe 22
Hole is provided on peep hole and opens peep hole and closed observation lid 23, peep hole it is convenient to the present embodiment carry out observation with
Maintenance.
