The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
The suspender of container handling crane and sling upper rack are all equipped with button lock, the utility model forms power sensor button lock by filled power sensor at button lock, button lock is subject to weight power to produce distortion thus, power sensor on it detects this distortion, form corresponding electric signal, by this electric signal, react the power of weight; Sensor electrical signal is sent to weight display by wire simultaneously, by heavy telltale, shows weight weight.According to power sensor button lock installation site difference, be divided into two schemes: scheme one, is arranged on the booster sensor button lock weighing system on container crane sling that is called on sling upper rack; Scheme two, the container crane sling power sensor button that is called being arranged on suspender is locked weighing system.
Example one, booster sensor button lock weighing system on container crane sling
Referring to Fig. 1 to 4, it is depicted as the structural representation of booster sensor button lock weighing system on container crane sling.
As seen from the figure, weighing system that this embodiment provides forms: 1 four jiaos of suspenders are respectively arranged with button lock 2(as shown in Figure 4), can be for lifting freight container by these four button locks 2,3 four jiaos of sling upper racks are respectively arranged with power sensor button lock 4(as shown in Figure 2), by this four power sensor buttons lock 4 for hoisting sling 1, the freight container that weigh suspender 1 and suspender can liftings simultaneously.One end of hoist rope 7 is fixed and on hoist rope reel 10, the other end of hoist rope 7 passes fixed pulley 8, then through sling upper rack fixed pulley 5, then through sling upper rack fixed pulley 6, through fixed pulley 9, be finally fixed in crane steel structure 11 again.The electric signal of sling upper rack power sensor button lock 4 is linked weight display 13 by wire 12.Weight display 13 specifically can be arranged in the control cabin of container handling crane, for accurately showing in real time the weight of hoisting heavy.
The up-and-down movement that rotarily drives hoist rope 7 of hoist rope reel 10, hoist rope 7 by added fixed pulley 5 and added fixed pulley 6, drive sling upper rack 3 liftings up and down, sling upper rack 3 drives suspender 1 lifting by sling upper rack power sensor button lock 4, and suspender 1 can play loaded container by suspender button lock 2.Sling upper rack power sensor button lock 4 can produce the electric signal of the Container Weight that reaction suspender 1 and suspender 1 can sling, and the electric signal of sling upper rack power sensor button lock 4 is connected with weight display 13 by wire 12, the weight display 13 demonstrations numerical value of weighing.Because sling upper rack power sensor button is locked 4 installation sites below hoist rope 7, so the weighing precision of booster sensor button lock weighing system is not subject to the impact of hoist rope 7 on container crane sling.
Example two container crane sling power sensor button lock weighing systems
Referring to Fig. 5 to Fig. 8, it is depicted as the structural representation of container crane sling power sensor button lock weighing system.
As seen from the figure, weighing system that this embodiment provides forms: 1 four jiaos of suspenders arrange respectively power sensor button lock 2(referring to Fig. 8), can be for lifting freight container by these four power sensor buttons locks 2, the suspender of simultaneously weighing can play the weight of loaded container; 3 four jiaos of sling upper racks are respectively arranged with button lock 4(referring to Fig. 6), by these four buttons locks 4 for hoisting sling 1.One end of hoist rope 7 is fixed and on hoist rope reel 10, the other end of hoist rope 7 passes fixed pulley 8, then through sling upper rack fixed pulley 5, then through sling upper rack fixed pulley 6, through fixed pulley 9, be finally fixed in crane steel structure 11 again.The electric signal of suspender power sensor button lock 2 is linked weight display 13 by wire 12.Weight display 13 specifically can be arranged in the control cabin of container handling crane, for accurately showing in real time the weight of hoisting heavy.
Hoist rope reel 10 rotarily drive the upper and lower of hoist rope 7, hoist rope 7 by added fixed pulley 5 and added fixed pulley 6, drive sling upper rack 3 liftings up and down, sling upper rack 3 drives suspender 1 lifting by sling upper rack button lock 4, and suspender 1 can play loaded container by suspender power sensor button lock 2.Suspender power sensor button lock 2 can produce the electric signal of the Container Weight that reaction suspender 1 can sling, and the electric signal of suspender power sensor button lock 2 is connected with weight display 13 by wire 12, the weight display 13 demonstrations numerical value of weighing.Because suspender power sensor button is locked 2 installation sites below hoist rope 7, so the weighing precision of container crane sling power sensor button lock weighing system is not subject to the impact of hoist rope 7.
Above-mentioned enforcement is mainly the application scheme of explanation the solution of the present invention in container handling crane, but the present invention is not limited to this, it also can be applicable to container crane sling power sensor button lock weighing system not have in the container handling crane of sling upper rack, overcomes the impact of hoist rope on freight container weighing precision.
More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
