Description

The ultra unbalance loading of vehicle-mounted container detects weighing system

Technical field

The utility model relates to the ultra unbalance loading of a kind of vehicle-mounted container and detects weighing system, belongs to container is surpassed the weighing technology field that unbalance loading detects.

Background technology

At present, overloading and unbalanced loading of container pick-up unit commonly used mainly contains track scale, truck scale, hang hook steelyard, container spreader scale etc.Track scale is after permutation car loaded, to detect, and is pretty troublesome if the ultra unbalance loading situation of appearance deals with, and wastes time and energy; The truck scale metering need be got gross weight earlier and allowanced for bark, and the container truck that runs into the two casees of delivery then needs to cross repeatedly weighing apparatus just can obtain each case weight; Hang hook steelyard can only be used on the suspension type machinery suspender, and is to improve operating efficiency container station to have adopted more advanced lifting spreader mostly, and hang hook steelyard can't supportingly use; The solution that the container spreader scale is on the contrary comparatively desirable; But need be equipped on all container cranes of participating in operation; If some container is to be hung when waiting other hoisting machinery operations of not equipping electronic scales by the front, these containers just can't obtain detecting, and utilize the container spreader scale to detect excess of export unbalance loading phenomenon during shipping by the time and reinform the words that the owner of cargo tallies; To obviously influence operating efficiency, delay shipping.Moreover; Whether the weighing-appliance as truck scale, hang hook steelyard detected set vanning gross weight merely overloads and can't detect its goods unbalance loading situation; And unbalance loading threatens the key factor of encased conveying safety exactly; So the container operation enterprise expects that still the overloading and unbalanced loading of container detection technique occurs more easily.

Summary of the invention

The technical scheme of the utility model realizes in the following manner:

The ultra unbalance loading of a kind of vehicle-mounted container detects weighing system; Comprise Weighing module, A/D module and intelligence instrument; Weighing module is connected with the A/D module through signal wire; The A/D module is that a conversion of signals and coding module, A/D module and intelligence instrument carry out signal transmission and reception through radio communication apparatus; Intelligence instrument demonstrates testing result after receiving signal that the A/D module sends, processing operations through radio communication apparatus on its screen, described Weighing module mainly by twistlock, briquetting, hold snip, LOAD CELLS constitutes, LOAD CELLS is installed in the vehicle frame of container truck; Briquetting is fitted on the LOAD CELLS, and twistlock passes briquetting, LOAD CELLS and vehicle frame from top to bottom, its lower end is equipped with handle and is used to pull twistlock realization solid and release to fastening of container; The described snip inboard of holding is connected with briquetting, and the outside is connected with vehicle frame, plays bearing container horizontal impact power and sealing function.

The described inboard inner pressure ring that passes through of snip that holds is connected with briquetting, and the outside is connected with vehicle frame through outer press ring.

Described LOAD CELLS is installed on the vehicle frame of container truck through pin or screw.

One cover vehicular overloading and unbalanced loading of container detects weighing system and comprises at least four Weighing modules.

The good effect of the utility model is:

Directly overloading and unbalanced loading of container being detected weighing system is installed on the container truck; Need not to make special weighing platform; In shipment, can realize the ultra unbalance loading of container is detected, even can survey by limit loading frontier inspection, avoid the overload or the unbalance loading of container cargo effectively.And, the utility model modular design, simple in structure, easy for installation, cost is low.

Embodiment

Below in conjunction with accompanying drawing the utility model is done further explain:

Can be found out by Fig. 1: the ultra unbalance loading of vehicle-mounted container detects weighing system and is made up of Weighing module 1, A/D module 2, intelligence instrument 3.Weighing module 1 is sent into A/D module 2 with the signal that collects through signal wire; A/D module 2 sends conversion of signals that obtains and coding afterwards through radio communication apparatus; Intelligence instrument 3 receives the signal that A/D module 2 is sent through radio communication apparatus, on its screen, demonstrates testing result after the processing operations.

Can find out by Fig. 2: Weighing module 1 mainly by twistlock 1-1, briquetting 1-2, hold snip 1-4, LOAD CELLS 1-6 constitutes; LOAD CELLS 1-6 is installed on the vehicle frame 1-8 of container truck through pin or screw; Briquetting 1-2 is fitted on the LOAD CELLS 1-6; Twistlock 1-1 passes briquetting 1-2, LOAD CELLS 1-6 and vehicle frame 1-8 from top to bottom, and its lower end is equipped with handle 1-9 and is used to pull twistlock 1-1 realization solid and release to fastening of container 4.

Can find out by Fig. 3: when container truck delivers two 20 forty equivalent unit 40 4-1 simultaneously; Anterior container detects through four groups of Weighing modules 1 of vehicle frame upper forepart; The container at rear portion detects through four groups of Weighing modules 1 at rear portion on the vehicle frame, the detection case of container before and after can checking respectively through the sense channel that switches intelligence instrument 3.

Can find out by Fig. 4: when container truck delivers 40 forty equivalent unit 40 4-2; Need be with twistlock 1-1, the handle 1-9 removal of the four groups of Weighing modules 1 in vehicle frame middle part, utilize vehicle frame two groups of

Weighing modules

1 and 1 pair of container of two groups of Weighing modules of rearmost end foremost to detect.

Can find out by Fig. 5: when 4 four jiaos in container drops on four 1 last times of Weighing module on the vehicle frame 1-8 respectively; Intelligence instrument 3 obtains 4 four jiaos of pressure to four Weighing modules 1 of container and is respectively: F1, F2, F3, F4, then the gross weight M=F1+F2+F3+F4 of container 4; Again according to torque equilibrium equation:

（F1+F3）*（Fx/2-X’）=（F2+F4）*（Lx+X’）

（F3+F4）*（Fy/2-Y’）=（F1+F2）*（Ly+Y’）

Solve: X '=[(F1+F3-F2-F4)/(F1+F2+F3+F4)] * Lx/2

Y’=[（F3+F4-F1-F2）/（F1+F2+F3+F4）]*Ly/2

Wherein: Lx is the distance between two corner fittings on container 4 length directions, and Ly is the distance between two corner fittings on container 4 Widths.

Thereby obtain projection X ' and the Y ' of bias on container 4 bottom surfaces that relative its centre of form O of container 4 center of gravity G points is ordered.

Like this, intelligence instrument 3 is the basis with F1, F2, F3, F4, calculates the gross weight M and projection coordinate X ' and the Y ' of container 4 centers of gravity on the bottom surface of container 4, and is presented on its screen, thereby realize that the utility model detects the ultra unbalance loading of container.
