Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
A kind of crane weighing force measurement device of the utility model, as shown in Figure 1, 2, it includes cylinder 4, boom system 7
With grab bucket 18,4 upper end of cylinder is equipped with oil drain pan 14, and 4 upper end of cylinder, which is bolted, installs ladder landing platform 15, on cylinder 4
Side is equipped with turntable 5, and right end is equipped with drivers' cab 10 on ladder landing platform 15, and 15 top of ladder landing platform, which is bolted, is equipped with change
Width driving device 6；
5 top left end of turntable is equipped with engine house 9, as shown in Figure 3,4, lifting mechanism 1, opening/closing machine is equipped in engine house 9
Structure 2 and rotating mechanism 3, lifting mechanism 1 are drivingly connected switching mechanism 2 and rotating mechanism 3；
Rotating mechanism 3 is mounted on 15 right end of ladder landing platform, as shown in figure 3, rotating mechanism 3 is surrounded by electrical system 17,
Rotating mechanism 3 is hinged with 7 low side of boom system；
Balance system 8 is installed, balance system 8 is connected by winding system 12 and boom system 7 in luffing driving device 6
It connects, 7 middle part of boom system is connect by stable rope 13 of grabbing bucket with 18 low sides of grab bucket, and grab bucket 18 is by being opened and closed restrict 11 and winding system
12 connections；
Winding system 12 is connect by steel wire rope with switching mechanism 2, and steel wire rope is wound as shown in Figure 5；
Weighing force measurement device is installed between the arm rack of boom system 7 and rotating mechanism 3 and on opening and closing rope 11；
Grab bucket 18 is idle double rope grab；
11 points of opening and closing rope is hoisting rope and grab bucket opening and closing rope.
Based on the above technical solution, overload device 16 is installed on ladder landing platform 15, overload device 16 with
Electrical system 17 is electrically connected.So set, when overload device 16 detects system excess load, by electrical system 17 into
Row adjustment.
The utility model is mounted on the grab bucket opening and closing rope of crane and the corresponding site of hoisting rope, passes through pulley and sensor
Reception steel wire rope tension measures lineoutofservice signal pull in real time can carry out PLC software programmings, set conventional wharf crane and normally transport
Turn rule, in crane key position installation rotated detection switch and multiple location information feedback points, pass through instrument and controller
The working condition in grab bucket current dynamometry converted weight and operation process can accurately be detected.Whenever a normal circulation of crane
Controller action is primary, and the data of weighing instrument automatically save once, so recycles, and it is invalid otherwise to weigh, and is thus avoided that
Situations about beating are duplicated when bringing down stocks more.
As shown in fig. 6, its workflow is：Weight signal, warp are first acquired by the multiple sensor being mounted on crane
Signal compensation adjusting circuit board sends the signal to A/D and converts-receive detectable signal integration unit, and carrying out A/D conversions will simulation
Signal is converted into digital signal, installs rotated detection by crane lower part after grab bucket is unloaded or overhead traveling crane shift motion detects
Switch measures grab bucket working order, is sent to A/D through detectable signal emitter and converts-receive detectable signal integration unit, locates
The processing of wireless data sending weight display is sent the signal to through metering crab bucket wireless data sending sending device after reason, and is kept records of same
When start printer printing automatically every time or grab buckets secondary be connected to after switching signal of making the return trip empty waited to preserve printing again, preventing from grabbing bucket exists
It does not debark when bringing down stocks duplicate printing and operative employee's cheating, so cycle finally summarize by accumulative total amount, number, time, date.Cause
This, can automatically weigh in dynamic and quiescent operation, count automatically, is automatic accumulative.There is character to show in operation, each press
Key sends out the sound in operation, can effectively pre- anti-misoperation.There is power-off data memory function, the data caused by power-off can be prevented
Loss causes dispute, and effective weight (rotated detection switchs, with reference to instrument program) can only be recorded every time by lifting by crane, full-automatic printing,
It can effectively prevent mistake.Be widely used in the Changjiang river marine site transfer, large, medium and small type port and pier, power plant, concrete stirring
It stands, the fields such as coal yard, the enterprises such as sandstone harbour, cement plant stevedoring bulk cargo Weighing, trade settlement internal examination.
Limitation to scope of protection of the utility model, those skilled in the art should understand that, in the skill of the utility model
On the basis of art scheme, the various modifications or variations that can be made by those skilled in the art with little creative work still exists
Within the scope of protection of the utility model.
