Abstract
The invention relates to the technical field of cranes, and provides a crane controlling system. The system comprises a direct-current speed-regulating system and a hydraulic system. The direct-current speed-regulating system comprises a direct-current speed regulator which is connected to a direct-current motor. The direct-current motor is connected to an oil pump used for providing hydraulic oil for the hydraulic system. The hydraulic system is connected with a hoisting mechanism, a luffing mechanism, a slewing mechanism, a traveling mechanism, and oil cylinders of a crawler crane. According to the invention, the direct-current motor is used for replacing a diesel engine, and the direct-current motor drives the oil pump for providing hydraulic oil for the operation mechanisms. The electric system and the hydraulic system are effectively and reasonably integrated, such that application and maintenance cost are greatly reduced. More importantly, clean electrical energy is used for replacing diesel oil, and no tail gas discharging is caused. Therefore, the crane controlling system provided by the invention has the advantage of environment friendliness.
Description
Technical field
The invention belongs to the hoisting crane technical field, relate in particular to a kind of crane control system.
Background technology
Crawler crane is that hoisting operation partly is contained on the crawler body, and walking relies on the runabout crane of crawler attachment.Can carry out the operations such as material lifting, transportation, loading and unloading and installation.Crawler crane has that load-carrying ability is strong, grounding pressure is little, turn radius is little, hill climbing ability greatly, does not need supporting leg, band carries and travels, job stabilization is good and the truss combined altitudes such as can freely change at the advantage, is widely used in the construction industries such as municipal administration, bridge, building.
At present, the employed control system of crawler crane generally adopts full hydraulic system or all-electric system.But all there is defective in these two kinds of control system, and are specific as follows:
Full hydraulic system is to drive each reductor, motor operations by the supporting oil pump of diesel motor, and the complete machine stable and reliable operation is simple to operate, and weak point is to use diesel oil to be propulsion source, and this is just so that the cost of operation and maintenance is very high;
All-electric system orders about each reductor work by electrical motor, although need not expend fuel oil, machine shape is huge, very heavy, and operating sequence is also very complicated.
Summary of the invention
The object of the present invention is to provide a kind of crane control system, all there is the problem of defective in the employed control system of hoisting crane that being intended to solve prior art provides.
The present invention realizes like this, a kind of crane control system, described system comprises Direct Current Governor System and hydraulic efficiency pressure system, described Direct Current Governor System comprises DC speed regulator, described DC speed regulator connects DC motor, and described DC motor connects the oil pump that is used to described hydraulic efficiency pressure system to supply hydraulic oil; Described hydraulic efficiency pressure system is connected with lifting mechanism, luffing mechanism, swing type mechanism, traveling gear and each oil cylinder of described crawler crane.
In the present invention, DC motor has replaced diesel motor, supply hydraulic oil by the DC motor drive oil pump for each operating unit, with power driven system and effective and reasonable the combining of hydraulic efficiency pressure system, use and maintenance cost have been reduced greatly, the more important thing is that the electric energy with cleaning has replaced diesel oil, do not had the discharging of tail gas, have stronger environment-friendly advantage.
Description of drawings
Fig. 1 is the structural representation of crane control system provided by the invention.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 shows the structural representation of crane control system provided by the invention, for convenience of explanation, has only provided part related to the present invention among the figure.
Crane control system provided by the invention comprises Direct Current Governor System and hydraulic efficiency pressure system, described Direct Current Governor System comprises DC speed regulator, described DC speed regulator connects DC motor 1, and described DC motor 1 connects the oil pump 2 that is used to described hydraulic efficiency pressure system to supply hydraulic oil; Described hydraulic efficiency pressure system is connected with lifting mechanism 3, luffing mechanism 4, swing type mechanism 5, traveling gear (not providing among the figure) and each oil cylinder of described crawler crane.
Wherein, the input end of described DC speed regulator connects the mouth of current colector (not providing among the figure), the input end of described current colector connects source of AC by cable, the 380V external AC power supply is linked on the current colector by cable, cable winding between source of AC and the current colector is on the cable drum of hoisting crane bottom, current colector is to be fixed on the center-rotary joint (not providing among the figure), turn round with swivel coupling, realize driven in synchronism, the cable connection of current colector mouth is positioned at DC speed regulator and the control system of getting on the bus, DC speed regulator connects DC motor 1, DC motor 1 links together by coupler 6 and oil pump 2, startup DC motor 1 drives immediately oil pump 2 and supplies hydraulic oil for each actuating unit, the hydraulic oil of upper frame part drives respectively lifting mechanism 3, luffing mechanism 4 and swing type mechanism 5, the hydraulic oil of lower frame part drives traveling gear by center-rotary joint.
In the present invention, DC motor has replaced diesel motor, supply hydraulic oil by the DC motor drive oil pump for each operating unit, with power driven system and effective and reasonable the combining of hydraulic efficiency pressure system, use and maintenance cost have been reduced greatly, the more important thing is that the electric energy with cleaning has replaced diesel oil, do not had the discharging of tail gas, have stronger environment-friendly advantage.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
