Background technology
At present, China's foreign trade is the gesture of continuous development, and particularly after accession to the WTO, the cargoes imported and exported amount continues sharp increase.How to measure the cargoes imported and exported amount more accurately, to guaranteeing that state tax revenue collects all due, stops to import and export abnormal activity in the declaration process, in-depth is implemented the fair enforcement of bonded area enterprise refund policy and improved the statistic of trade and the data management system of business statistics, setting up tight active data Quality Ensuring Mechanism all has profound significance.
All need to have enough to meet the need because all import and export containers through the container wharf, and use the container in tire type crane to lift to be in this circular flow must be through link; Each container must make the turnover of container waste time and energy through weighing link again simultaneously.Enclosed construction owing to container makes the lifting personnel can't know whether container is overweight or not local not overweight in addition, thereby causes the lifting accident.
Patent Office of the People's Republic of China has announced a CN2887820Y document on April 11st, 2007, name is called wheel-mounted crane, this crane comprises car body, car body is provided with the lifting beam that is made of some joint box-shaped arms and has the supporting leg of outer tube, lifting beam is provided with the wire rope that is subjected to hydropress control, and hydropress is provided with equalizing valve.The wheel-mounted crane wire rope can at the uniform velocity rise and fall, and stability improves greatly, and accurate positioning.The shortcoming of this crane is to weigh in lifting, and overweight or monolateral when overweight when being existed by the hoisting thing, can not report to the police and protect.
Summary of the invention
The problem that the utility model can not be weighed in the lifting circular flow simultaneously for the harbour container that exists in the solution prior art provides a kind of container in tire type crane weighing system that can weigh when lifting; Overweight or monolateral when overweight when being existed by the lifting container, report to the police.
The technical scheme that its technical matters that solves the utility model adopts is: the utility model comprises the container in tire type crane, also comprise weighing system, weighing system comprises LOAD CELLS, chromacoder, control device, weight display device, data transmission and treating apparatus; LOAD CELLS links to each other with the input end of chromacoder, and the output terminal of chromacoder links to each other with the input end of control device, weight display device, and the output terminal of weight display device links to each other with treating apparatus with data transmission.Each lifting rope of container in tire type crane links to each other with suspender by LOAD CELLS, when lifting during container, and the weight that each LOAD CELLS is accurately measured each wire rope and born; LOAD CELLS is sent to chromacoder with the voltage signal that records, chromacoder is sent to control device respectively with the voltage signal of each LOAD CELLS, whether control device exists overweight or monolateral overweight judgement, when there being the overweight or monolateral overweight warning of then sending; The synchronous signal conversion equipment is handled the gross weight signal that obtains container with the voltage signal of each sensor, and is sent to the weight display device and shows; The weight display device sends to data transmission and treating apparatus with the gross weight signal of each container, work such as data transmission and treating apparatus are added up, form.
As preferably, LOAD CELLS has four, and described LOAD CELLS is a high-precision sensor.Four sensors are corresponding to four lifting wire rope, and the precision of each sensor is up to C2 level (reference to standard GB/T7551-2008/OIML R60).
As preferably, chromacoder comprises special junction box, and special junction box comprises the change-over circuit that can realize signal allocation, realize single sensor multiple signals output; The voltage signal of four sensor outputs links to each other with the input end of change-over circuit, and the output terminal of change-over circuit links to each other with the input end of control device, weight display device respectively.Special junction box is installed in the position near four sensors, carries out conversion of signals, and voltage signal is converted to current signal, to reduce the decay and the distortion of signal; Each sensor weight signal after change-over circuit will be changed is sent to control device, and the gross weight signal is sent to the weight display device.
As preferably, control device comprises four control instruments, PLC controller and alarm, the input end of four control instruments links to each other with the output terminal of chromacoder, and the output terminal of four control instruments links to each other with the input end of PLC, and the output terminal of PLC links to each other with alarm.Control instrument can carry out the setting of each wire rope freight weight limit value, and with the input analog quantity change switching value into, when the analog quantity of input has surpassed setting value, switching value of control instrument output is given the PLC controller, so that the PLC controller is protected action and reported to the police and handle; Control instrument also can show the weight that each wire rope bears simultaneously.
As preferably, the weight display device is the weight Displaying Meter.Characteristics easy to use, that display precision is high, price is low that the weight Displaying Meter has.
As preferably, data transmission and treating apparatus comprise host computer and data center, and the host computer input end links to each other with the weight display device by PORT COM, and the host computer output terminal links to each other with data center with receiving trap by wireless transmission.Host computer carries out the statistics of data and the work of form; Because the container in tire type crane is a movable equipment, therefore adopt wireless transmission to link to each other with data center with receiving trap, data center carries out the concentrated statistics and the form of each container in tire type crane lifting data.
The beneficial effects of the utility model are: weigh in container transshipment, simplified the work at harbour, thereby have very big economic worth; When lifting, not only the gross weight of container is carried out overweight protection and warning, can also carry out overweight protection and warning to the load capacity of every wire rope, improve the security of container in tire type crane.
