The crane and the movable trolley can be in suspension state under the action of magnetic force between the end beams and the tracks and can completely realize non-contact drag and brake. The influence of the unevenness of the friction and a sloping way on the running of the crane is avoided, and simultaneously, the problems of mechanical noise and abrasion and the like are also solved. The magnetic suspension wheelless rail type crane has the advantages of safety, reliability, high speed, high efficiency and long service life.

Description

Magnetic levitation wheelless track type crane
Technical field
The utility model relates to a kind of magnetic levitation wheelless track type crane.
Background technology
The operation scheme of hoisting crane has only two kinds both at home and abroad: rail form (the girder wheel moves on fixing rail) and trackless (no trapped orbit is by tire or crawler belt supporting operation).Driving system generally has forms such as mechanical drive, hydro-mechanical transmission, static pressure transmission and electro-mechanical transmission.Known locomotive crane structure is: support main beam is arranged, be hinged with the longitudinally end carriage and the roller thereof of track travel at the support main beam two ends, parallel on girder two cross tracks are installed, on two cross tracks, be movably installed with travelling car and end carriage thereof and roller, the lifting mechanism of lifting object is installed on travelling car.This hoisting crane is not steady at walking speed per hour degree, and its reason is due to the variation of resistance of motion.Running resistance is mainly come the unequal external force that contacts in self-friction and ramp.Therefore locomotive crane can't overcome friction and the influence of ramp injustice to operation, this hoisting crane mechanicalness noise and serious wear in addition.
Summary of the invention
The utility model provides a kind of magnetic levitation wheelless track type crane that operates steadily for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
A kind of magnetic levitation wheelless track type crane, be characterized in: the support main beam two ends are connected with along the crane end carriage of hoisting crane orbit walking, the parallel trolley travelling track that is equipped with on girder, on the trolley travelling track, be movably installed with travelling car and end carriage thereof, the lifting mechanism of lifting object is installed on travelling car.Described hoisting crane orbit is a H shaped steel, and the crane end carriage lower end is shaped on the T slot with hoisting crane orbit coupling, in this notch electromagnet is installed, and the waist of hoisting crane orbit and top correspondence are equipped with the coil winding that produces magnetic field; Described trolley travelling track also is a H shaped steel, and dolly end carriage lower end is shaped on the T slot with the trolley travelling Orbit Matching, in this notch electromagnet is installed, and the waist of trolley travelling track and top correspondence are equipped with the coil winding that produces magnetic field.
Advantage and the good effect that the utlity model has are:
Because electromagnet and coil winding are set between track and end carriage, make hoisting crane have contactless electromagnetic suspension, guiding and drive system, making hoisting crane not have machinery with interorbital when running under power contacts, fundamentally overcome the influence of friction and ramp injustice, also solved problems such as mechanicalness noise and wearing and tearing simultaneously the hoisting crane operation.The utility model also has the advantage of safe and reliable, high-speed and high-efficiency, long service life in addition.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the I portion enlarged drawing of Fig. 1;
Fig. 3 is that the A of Fig. 1 is to view.
Among the figure: 1, crane end carriage; 2, hoisting crane orbit; 3, girder; 4, table balustrade; 5, lifting mechanism; 6, dolly; 7, dolly end carriage; 8, trolley travelling track; 9, coil winding; 10, electromagnet; 11, electromagnet; 12, coil winding; 13, coil winding; 14, electromagnet; 15, electromagnet; 16, coil winding.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As Fig. 1~shown in Figure 3, support main beam 3 two ends are connected with along the crane end carriage 1 of hoisting crane orbit 2 walkings, the parallel trolley travelling track 8 that is equipped with on girder, on the trolley travelling track, be movably installed with travelling car 6 and end carriage 7 thereof, the lifting mechanism 5 of lifting object is installed on travelling car.Described hoisting crane orbit is a H shaped steel, the crane end carriage lower end is shaped on the T slot with hoisting crane orbit coupling, electromagnet 10,11 is installed in this notch, and the waist of hoisting crane orbit and top correspondence are equipped with the coil winding 9,12 that produces magnetic field.Described trolley travelling track also is a H shaped steel, and dolly end carriage lower end is shaped on the T slot with the trolley travelling Orbit Matching, and electromagnet 14,15 is installed in this notch, and the waist of trolley travelling track and top correspondence are equipped with the coil winding 13,16 that produces magnetic field.Like this, because electromagnet and coil winding are set between track and end carriage, make hoisting crane have contactless electromagnetic suspension, guiding and drive system, making hoisting crane not have machinery with interorbital when running under power contacts, fundamentally overcome the influence of friction and ramp injustice, also solved problems such as mechanicalness noise and wearing and tearing simultaneously the hoisting crane operation.The utility model also has the advantage of safe and reliable, high-speed and high-efficiency, long service life in addition.
Principle of work
During the hoisting crane operation, the magnet antagonistic force that the electromagnet of crane end carriage T slot mouth and the winding of orbit both sides produce floats hoisting crane.The guidance system of magnetic suspension hoisting crane mainly depends on track waist coil and hoisting crane T slot mouth vertical plane electromagnet mutual action is realized.At crane end carriage notch vertical plane one group of electromagnet that is specifically designed to guiding is installed, when being offset about hoisting crane takes place, the guiding electromagnet of end carriage notch vertical plane and track waist coil winding mutual action produce repulsive force, make hoisting crane restoring running normal position.Guidance system relies on the coil of track waist, according to the size of the required cross dip of reality, the exchange current in the coil is regulated, and then required guidance force is provided.In addition because suspension and guiding are in fact irrelevant with running velocity, so even hoisting crane still can enter suspended state under dead ship condition.The stability of hoisting crane is controlled by guidance system.
