Abstract
The utility model relates to a bridge type hoisting equipment, in particular to an electromagnetic crane, which comprises a bridge frame (1), a trolley (2) and an electromagnetic hanging beam (4), wherein the trolley (2) is arranged on the bridge frame (1), electromagnets (5) for adsorbing steel products are hung on the electromagnetic hanging beam (4) through a chain, a telescopic beam (6) capable of moving relative to the electromagnetic hanging beam (4) is also arranged on the electromagnetic hanging beam (4), and at least one electromagnet (5) is also arranged on the telescopic beam (6). The electromagnetic crane has the advantages that the number of the electromagnets required to be used can be regulated according to the length dimension of the steel products to be hoisted, so the work efficiency during steel product hoisting is high, and in addition, safety and reliability are realized.
Description
Technical field
The utility model relates to a kind of overhead and gantry cranes, relates in particular to a kind of magnet crane.
Background technology
Magnet crane mainly is applicable in shipbuilding yard and some the steel member workshops, is used for carrying steel, in the process of the magnet crane handling steel of prior art; When the steel length dimension of slinging hour; Several electromagnet can be adsorbed on the steel in the middle of having only, and the load that will cause each to be adsorbed on the electromagnet on the steel like this is heavier, and surpass the heavy burden limit of electromagnet sometimes; Thereby absorption is steel incessantly; Produce potential safety hazard, the working ability of hoisting crane is not brought into play fully yet simultaneously, causes the waste of production capacity; When the steel length dimension of slinging is big; Though all electromagnet all have been adsorbed on the steel, generally all only be adsorbed on the centre portion of steel length, do not adsorb all parts of steel length; Like this when lifting steel may overbalance, rock, be easy to generate potential safety hazard.
Summary of the invention
The utility model technical matters to be solved is: a kind of magnet crane is provided, and it can adjust the number of the required electromagnet of using, high efficiency and safe and reliable when making its lifting steel according to the length dimension of lifting steel.
The technical scheme that the utility model adopted is: a kind of magnet crane; Comprise crane span structure, dolly, electromagnetic suspended beam; Said dolly is located on the crane span structure, and said electromagnetic suspended beam hangs on the dolly through steel rope, also hangs with the electromagnet that is used for adsorbing steel through chain on the said electromagnetic suspended beam; Also be provided with on the described electromagnetic suspended beam and the relatively-movable telescopic girder of electromagnetic suspended beam, also be provided with at least one electromagnet on the said telescopic girder.
Adopt above structure compared with prior art; The utlity model has following advantage: on electromagnetic suspended beam, be provided with telescopic girder; And telescopic girder and electromagnetic suspended beam can relatively move, and when the lifting steel, can regulate the position of telescopic girder like this, and then adjust the required electromagnet number of using; So promptly can increase work efficiency, can guarantee to lift by crane safe and reliable again.
As improvement, also be provided with equalizing bar and swivel bearing between said dolly and the electromagnetic suspended beam, said equalizing bar hangs over the dolly below through steel rope or suspension hook, and said swivel bearing is connected between equalizing bar and the electromagnetic suspended beam.The design electromagnetic suspended beam just can rotate freely like this, does not just receive the restriction of steel putting position during steel in lifting, and the orientation that only needs to adjust electromagnetic suspended beam can make the putting position of position and steel of electromagnet consistent, and operation is simple.
As improvement, also be provided with backup power on the magnet crane, said backup power is connected with electromagnet and control system thereof.When the operation electrical network has a power failure suddenly, but auto switching electric source guarantees that in setting-up time absorbate can not drop because of outage, and will be put down assurance user's equipment and personal security by lifting thing safety;
As improvement, described relatively moving is meant that the electromagnetic suspended beam both sides all are provided with track, and said telescopic girder is provided with running wheel, and said running wheel matches with track.Like this easy design telescopic girder on electromagnetic suspended beam, move.
Description of drawings
Accompanying drawing is the structural representation of the utility model magnet crane.
As shown in the figure: 1, crane span structure; 2, dolly; 3, equalizing bar; 4, electromagnetic suspended beam; 5, electromagnet; 6, telescopic girder; 7, swivel bearing; 8, the flexible motor of control; 9, control motor rotating.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is done to further describe, but the utility model is not limited only to the following specific embodiment.
Shown in accompanying drawing, a kind of magnet crane comprises crane span structure 1, dolly 2, electromagnetic suspended beam 4; Said dolly 2 is located on the crane span structure 1; Said dolly is provided with lifting mechanism, is wound with steel rope on the said lifting mechanism, and steel rope links to each other with equalizing bar 3 through assembly pulley or suspension hook; Said equalizing bar 3 is connected with electromagnetic suspended beam 4 through swivel bearing 7, and the outside of said swivel bearing 7 is connected with equalizing bar 3, inside links to each other with electromagnetic suspended beam 4.Also hang with the electromagnet 5 that is used to adsorb steel on the said electromagnetic suspended beam 4 through chain; Also be provided with on the said electromagnetic suspended beam 4 and electromagnetic suspended beam 4 relatively-movable telescopic girdeies 6; Described relatively moving is meant that said electromagnetic suspended beam 4 two ends are provided with track, and said telescopic girder 6 is provided with running wheel, and said running wheel matches with track; Also be provided with at least one electromagnet 5 on the said telescopic girder, be provided with two electromagnet for each telescopic girder 6 shown in the figure.
Supporting on the said electromagnet 5 have a backup power, and said backup power can be installed in a lot of places, as above the equalizing bar 3, electromagnetic suspended beam 4 sides etc.; Described backup power adopts valve-regulated completely-sealed lead-acid maintenance-free battery; Charging modes is that constant voltage and current limiting charges automatically, overcharges automatically and places restrictions on, and crosses and puts warning; Need manual work on duty, do not need frequent maintenance.
Described electromagnet 5 shapes that are used for adsorbing steel are not necessarily rectangular, and it can select for use dissimilar according to concrete shape, the weight of hoisting heavy, can be circular or other shape.
The utility model magnet crane is to adopt electric centralized control; It is provided with an operator's compartment; Be connected to the flexible motor 8 of control, control motor rotating 9 and electromagnet 5 etc. on the control system in the operator's compartment then; Operating personal only need control button and just can control flexible, the rotation of electromagnetic suspended beam of telescopic girder and the break-make electricity of electromagnet etc. like this, and is simple to operation.
