Abstract
The invention discloses a swinging arm type suspension crane which is characterized by comprising a swinging arm type suspension crane car, swinging arms, a swinging arm type crane main beam, a lifting gourd and a lifting hook; the swinging arm type suspension crane car is hung below a universal bridge-type crane main beam and can operate in the direction of the universal bridge-type crane main beam; the two swinging arms, the swinging arm type suspension crane car and the swinging arm type crane main beam are connected to form a four-bar mechanism through pin shafts; and an ejecting device which can push the swinging arms to swing is further arranged on the swinging arm type suspension crane car. The swinging arm type suspension crane can be used for lifting objects outside the cart track; and when the suspension crane does not operate, the suspension main beam can be accommodated at the bottom of the universal bridge-type crane main beam, so that the suspension main beam is prevented from interfering with equipment in a factory building when operating along with a universal bridge-type crane.
Description
Technical field
the present invention relates to a kind of elevator machinery, especially a kind of swing arm type overhang crane.
Background technology
overhang crane is combined by assemblies such as suspension gear, track, track switch, walking dolly, electric block, mobile power supply device (slip) and control setups.Because this overhang crane only need be suspended on the aerial directly conveying that factory building top board or roof beam structure just can realize material simply, be therefore widely used in mass transport link or the system of all trades and professions.But existing overhang crane cannot arrive in large Car Track and get thing, cannot meet the demands to specific occasion, therefore there is a kind of telescopic girder hoisting crane, exactly between crane girder or under a telescopic girder is housed, different according to design, it can stretch out track from one side or both sides, and telescopic girder hoisting crane can to very inapproachable regional service, such as, region between column.But this telescopic girder crane structure is complicated, stressed little, safeguard inconvenient.
Summary of the invention
the present invention seeks to: provide a kind of structure simple, easy to maintenance, can be used in the article outside the large Car Track of handling, during not operation simultaneously, suspension girder being closed at bottom general-purpose overhead crane girder, avoiding hanging girder when running with general-purpose overhead crane with the swing arm type overhang crane that equipment in factory building is interfered.
technical scheme of the present invention is: a kind of swing arm type overhang crane, it is characterized in that, comprise swing arm type overhang crane dolly, swing arm, swing arm type crane main beam, lifting hoist and suspension hook, can to run along described general-purpose overhead crane girder direction under described swing arm type overhang crane dolly is suspended on general-purpose overhead crane girder, described two swing arms and swing arm type overhang crane dolly, a four-bar linkage is formed by bearing pin between swing arm type crane main beam, described swing arm type overhang crane dolly is also provided with the ejector apparatus that can promote described swing arm and swing.
further, described ejector apparatus comprises base and swing arm oil cylinder, and described base is positioned at bottom swing arm type overhang crane dolly, and described seat is connected with swing arm by swing arm oil cylinder.
further, described ejector apparatus is 1.
further, described base is positioned at bottom swing arm type overhang crane dolly, and between two swing arms.
advantage of the present invention is:
1. can be used for the article outside the large Car Track of handling, during not operation simultaneously, suspension girder be closed at bottom general-purpose overhead crane girder, avoid hanging girder and interfere with equipment in factory building when running with general-purpose overhead crane;
2. relative to telescopic girder hoisting crane, structure is more simple and reliable, and maintenance is convenient.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the invention will be further described:
fig. 1 is swing arm type overhang crane structural representation of the present invention.
wherein: 1 general-purpose overhead crane; 2 swing arm type overhang crane dollies; 3 swing arms; 4 swing arm oil cylinders; 5 bases; 6 electric blocks; 7 swing arm type crane main beams; 8 load hooks.
Detailed description of the invention
embodiment: swing arm type overhang crane as shown in Figure 1, comprise swing arm type overhang crane dolly 2, swing arm 3, swing arm type crane main beam 7, electric block 6 and load hook 8, swing arm type overhang crane dolly 2 is suspended on general-purpose overhead crane girder 1 time and can runs along the girder direction of described general-purpose overhead crane 1, forms a four-bar linkage between two swing arms 3 and swing arm type overhang crane dolly 2, swing arm type crane main beam 7 by bearing pin.Be provided with base 5 bottom swing arm type overhang crane dolly 2, base 5 is connected with swing arm 3 by swing arm oil cylinder 4.Base in the present embodiment is positioned at bottom swing arm type overhang crane dolly, and between two swing arms, also can be positioned at other positions, equally can realize function of the present invention.The ejector apparatus be made up of base and swing arm oil cylinder can be 1, also can be multiple.During mode of operation, control swing arm oil cylinder 4 promotes swing arm 3 and moves, swing arm type crane main beam just can be made to move to both direction, thus add scope of work, during not operation simultaneously, suspension girder is closed at bottom general-purpose overhead crane girder, avoid hanging girder and interfere with equipment in factory building when running with general-purpose overhead crane.
the above, be only the detailed description of the invention of invention.Protection scope of the present invention is not limited thereto, and is anyly familiar with those skilled in the art in the technical scope that the present invention discloses, the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should define with claim is as the criterion.
