The intelligent control system of the crane has the advantages that an operation system is an intelligent control system based on the CAN bus technology; the control system is convenient and quick to operate, good in operation view, simple in connection of circuits, beautiful and elegant in layout, strong in anti-interference capability and comfortable and convenient to operate; by virtue of the control system, the technical performance of the overall crane reaches an international advanced level, and is placed in the lead level in our country.
Description
Technical field
The utility model relates to a kind of electrohydraulic control system of hoisting crane, particularly a kind of crane intelligent control system.
Background technology
At present, hoisting crane is because applied range, work efficiency is high and the life-span is long etc., and advantage is widely used in many fields, and market is very powerful.But because hoisting crane is usually in the operation of the place of very severe, the safety of operation usually can not guarantee have accident to occur frequently, this is not high closely bound up with monitoring degree.
Utility model content
The purpose of this utility model is to provide a kind of: operating characteristic is good, control ability is strong, applied widely, commonality good, safe limit and System self-test improve and the strong crane intelligent control system of antijamming capability.
The purpose of this utility model is achieved in that described control system, coder and controller communicate by CANBUS, and oil pressure sensor, approach switch, switch of inclination, unloading electromagnetic valve and indicator lamp carry out the transmission of information by the I/O interface of controller; In two vertical leg, oil pressure sensor is installed, on two horizontal support legs, approach switch is installed, coder is installed at turntable transmission device place, two unloading electromagnetic valves are installed in the oil circuit of rotating both direction, at turntable place mounted angle switch, at the large loculus of the first amplitude oil cylinder, two oil pressure sensors are installed.
Beneficial effect, owing to having adopted such scheme, controller focuses on information, makes data connection and transmission very reliable, has brought into play to greatest extent the power of hardware device, has improved antijamming capability.Realized subregion control; the subregion of hoisting crane is controlled can bring into play maximum transaction capabilities by assurance equipment; can automatically determine operating area according to the state of different supporting legs; also can carry out the judgement of sky hook, anti-rollover protection and pressure alarm simultaneously; thereby improved the safety and stability of work; promoted equipment performance; design aesthetic in appearance generous; operate comfortable; safe, accurately, work efficiency is high in action; broken that electrical control system of crane is simple, operating efficiency is low and the situation of poor stability, realized the purpose of this utility model.
Advantage: this operating system is the intelligent control system based on CAN bussing technique, convenient to operation, the operation visual field is good.Car load has subregion and controls function, according to the state that stretches out of supporting leg, is divided into four kinds of work areas: circular maximum operation district, can carry out 420 ° of (± 210 °) operations, and be applicable to most service conditions; Large fan-shaped one-side operation district, can carry out 240 ° of operations, is applicable to the one-side operation of a side narrow space; Little fan-shaped adjustment operating area, can carry out 60 ° of operations, is applicable to the adjustment of wagon box goods and operation among a small circle; Forbid operating area, vertical leg is not normally landed, and can not move loop wheel machine.Subregion is controlled, and can not only adapt to the various complex working conditions of operation, can also reach maximum operating efficiency.Meanwhile, system also has service conditions judgement, empty hook judgement, pressure alarm and anti-rollover protection, has improved the safety and reliability of equipment.Connection is simple, and layout is elegant in appearance, and antijamming capability is strong, and operation comfort and convenient makes the technical performance of car load reach domestically leading, international advanced level.

The specific embodiment
Embodiment 1: described intelligent control system, and in two vertical leg, to install on oil pressure sensor and two horizontal support legs approach switch is installed, the information that controller collects according to above device is determined work area; Coder is installed at transmission device place at turntable, and controller carries out the division of work area according to the angle information of coder collection; Two unloading electromagnetic valves are installed in the oil circuit of rotating both direction, for the break-make of two gyratory directions oil circuits; At turntable place mounted angle switch, for the judgement of service conditions; In addition, at the large loculus of the first amplitude oil cylinder, the detection that two oil pressure sensors judge empty hook and pressure early warning point is installed.Coder and controller IO_MODULE communicate by CANBUS, and oil pressure sensor, approach switch, switch of inclination, unloading electromagnetic valve and indicator lamp carry out the transmission of information by the I/O of controller, and its circuit diagram as shown in Figure 2.
In Fig. 3, the 10 tons of forestry cranes of take are example, mainly vertical leg 1, horizontal support legs 2, turntable 3, the first amplitude oil cylinder 4, inner arm 5, the second amplitude oil cylinder 6 and outer arm 7 etc., consist of.
This forestry crane operation action is very abundant, can complete as required the operations such as loading, transportation, unloading, and according to the difference of gripping apparatus, manipulating object can be timber, native sand and rubbish etc.
In order to realize subregion, control, in two vertical leg, oil pressure sensor is installed, judge whether vertical leg normally lands; On two horizontal support legs, approach switch is installed, for detection of horizontal support legs, whether is entirely reached position; Bus-type coder has been installed on turntable, for the detection of degreeof turn; Like this, controller has been determined work area according to supporting leg state, controls the break-make of the unloading electromagnetic valve of both direction according to degreeof turn, thereby realize subregion, controls.Can normally turn round and prevent overload when guaranteeing zero load, on the large loculus of the first amplitude oil cylinder, two oil pressure sensors have been installed, for judgement and the pressure alarm of empty hook.In order to judge the reliable of service conditions, switch of inclination has been installed on turntable, for detection of maximum functional inclination angle.
