Description
Technical field
The present invention relates to magnetic suspension crane field, specially a kind of remote control grab bucket crane.
Background technology
Existing wheel-mounted crane is by crawler crane（Crawler crane）Differentiation is formed, by the crawler belt of walking mechanism and walking
Holder part becomes the chassis for having tire, overcomes crawler crane（Crawler crane）The shortcoming that creeper tread road pavement is damaged.
The work characteristics that crane gear has is to do intermittent exercise, i.e., the phase of the action such as feeding, migration, unloading in a working cycles
It is alternation to answer mechanism, crane development commercially and using more and more extensive.Due to without supporting leg lift heavy and hanging
Overline is sailed often there are some accidents, and the speed of traveling is also compared with crawler crane（Crawler crane）Hurry up；Operation is stable, lifting capacity is big,
Lift heavy can walk but must assure that path formation is solid, tire pressure meets the requirements, hang ground and must not surpass in particular range
Cross 50CM；On-load is forbidden to walk over long distances.To ensure job safety, the country substantially forbids not making a jack being lifted at present
Operation.
The method of operation of current crane has two kinds：One kind is that rail form (on fixed rail transport by girder wheel
OK), another kind is trackless (without trapped orbit, by tire or crawler belt supporting operation).Transmission system typically has machine driving, liquid
The forms such as press mechanical pressing transmission, motor machine transmission.We are at well known locomotive crane structure：There is support main beam, carrying
Girder two ends are hinged with the end carriage and its roller walked along long rails, parallel on girder to be provided with two cross tracks,
Locomotive and its end carriage and roller are movably installed with two cross tracks, the lifting machine of lifting object is installed in moving cart
Structure.
Speed is unstable when walking for existing grab bucket crane, clamshell crane, and its reason is the resistance of motion, causes fortune
Capable resistance is essentially from friction and the external force of the unequal contact of track, road, therefore locomotive crane cannot overcome friction
The influence of operation, the crane mechanicalness noise and serious wear, troublesome poeration, and the professional driver of needs drive and grasp in addition
Make, large-scale equipment needs the human users of two or the above, and the speed of service and reflection speed slow, work effect all more
Rate is had a greatly reduced quality.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of remote control grab bucket crane, with solution
The problem proposed in background technology is stated, the present invention utilizes maglev principle, by electromagnet and the fortune of crane end carriage T-slot mouthful
The magnet reaction force that the winding of row track both sides is produced floats crane.The friction with guide rail is reduced, its two end arms beam can
