Utility model content
In view of this, the purpose of this utility model is to propose a kind of gantry crane that is exclusively used in high precision carrying steel plate.
A kind of gantry crane providing based on above-mentioned purpose the utility model, comprises frame, and described frame has two relative wallboards, also comprises two trave lling girders, two lift beams and four groups of lifting mechanisms; The upper limb of described two wallboards all arranges upper rail, and described in each, trave lling girder all can move along described two upper rails in horizontal surface; Described in each, lift beam is all connected with a described trave lling girder by lifting mechanism described in two groups, and described lifting mechanism can drive described lift beam up-and-down movement in perpendicular, and described lift beam bottom is also provided with a plurality of lifting magnet suckers.
Preferably, also comprise lower guideway, described frame can move along described lower guideway.
Preferably, described two wallboard lower ends arrange the lower driven wheel matching with described lower guideway, by lower driven wheel described in driven by servomotor, described frame can be moved along described lower guideway.
Preferably, described trave lling girder two ends arrange the upper driven wheel matching with described two upper rails, by upper driven wheel described in driven by servomotor, described trave lling girder can be moved along described two upper rails.
Preferably, described lifting mechanism is ball-screw.
As can be seen from above, a kind of gantry crane that the utility model provides, by trave lling girder, along the movement of upper rail, realize steel plate allocation and transportation in the horizontal direction, by lift beam, with the rising of lifting mechanism and decline, realize steel plate in the allocation and transportation of vertical direction, with single, compact single unit system, replace existing many equipment in conjunction with mode of operation, improved allocation and transportation precision; Meanwhile, by each allocation and transportation action of driven by servomotor, further guarantee allocation and transportation precision.

The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the utility model is further described.
The utility model embodiment provides a kind of gantry crane, comprises frame, and described frame has two relative wallboards, also comprises two trave lling girders, two lift beams and four groups of lifting mechanisms; The upper limb of described two wallboards all arranges upper rail, and described in each, trave lling girder all can move along described two upper rails in horizontal surface; Described in each, lift beam is all connected with a described trave lling girder by lifting mechanism described in two groups, and described lifting mechanism can drive described lift beam up-and-down movement in perpendicular, and described lift beam bottom is also provided with a plurality of lifting magnet suckers.
With reference to figure 1 and Fig. 2, be respectively the gantry crane structural representation of the utility model embodiment and the birds-eye view of Fig. 1.
The gantry crane of the present embodiment, comprises that described frame 1 comprises two relative wallboards 2 for supporting integral structure and the frame 1 that associated mechanisms is set.The upper limb of two wallboards is provided with upper rail 5.Two trave lling girders 3 are arranged on two upper rails 5, two trave lling girders 3 be parallel to each other and with two vertical settings of wallboard 2.By mechanism, coordinate, trave lling girder 3 can move along two upper rails 5 in horizontal surface.Two groups of lifting mechanisms 6 that are provided with on each trave lling girder 3 on 6, one trave lling girders 3 of two groups of lifting mechanisms are fixedly connected with a lift beam 4.By lifting mechanism 6, drive lift beam 4 up-and-down movement in perpendicular.The bottom of lift beam 6 is also provided with a plurality of lifting magnet suckers 7, by electromagnet, is switched on and is produced magnetic force and hold steel plate.
As an embodiment, the gantry crane of the present embodiment also includes lower guideway 8, and frame 1 is arranged on described lower guideway 8, by mechanism, is coordinated and can be realized frame 1 along lower guideway 8 shift positions.Can, according to actual need of work, select to arrange the set-up mode of lower guideway 8, to realize the moving direction of different frame 1.As preferably, the lower end of two wallboards 2 is provided with lower driven wheel (not shown), and described lower driven wheel matches with lower guideway 8, and it is by driven by servomotor, can realize the accurate control of miles of relative movement.
In the present embodiment, the two ends of two trave lling girders 3 are provided with driven wheel (not shown), described upper driven wheel matches with two upper rails 5, and upper driven wheel, by driven by servomotor, can be realized and make trave lling girder 3 do accurate movement along upper rail 5.
As preferably, described lifting mechanism 6 is ball-screw, and concrete, it comprises nut and pilot bar.Lift beam 4 is fixedly connected with described nut, pilot bar vertically arranges and is driven and rotated by motor, nut can change into straight-line motion according to the helical pitch of corresponding specification with the rotational angle of pilot bar, thereby realize, drives lift beam 4 in perpendicular, to do straight-line motion.
During work, first lifting mechanism 6 drives lift beam 4 to drop to steel plate place, and 7 energisings of lifting magnet sucker produce magnetic force steel plate is held, and lifting mechanism 6 and then drive lift beam 4 rise, and steel plate is risen.Under driven by servomotor, two trave lling girders 3 can move along the upper rail 5 of wallboard 2 upper limbs in horizontal surface, realize the parallel motion that lift beam 4 drives steel plate.The lower driven wheel of driven by servomotor wallboard 2 lower ends, makes frame 1 move along lower guideway 8, further the allocation and transportation position of accurate adjustment steel plate.
