Abstract
The invention relates to an electric crane with a limiting device which comprises a fixed upright column, a suspension arm and a power device, wherein one end of the suspension arm is fixedly connected to the fixed upright column; one end of the suspension arm away from the fixed upright column is provided with a pulley, and the pulley is arranged on the suspension arm by a pulley seat; a hoisting chain led out by the power device winds around the pulley and then extends downwards, and one end of the hoisting chain is connected with a hoisting hook; one end of the suspension arm away from the fixed upright column is provided with a limiting device; and the limiting device comprises a limiting rotary shaft, a limit switch, a baffle ring and a baffle plate, wherein the limiting rotary shaft is rotatablely arranged on the suspension arm, the limit switch is fixed at one end of the limiting rotary shaft, one end of the baffle ring is fixedly connected to the limiting rotary shaft and can move with the limiting rotary shaft, the baffle plate is fixedly arranged at the other end of the baffle ring and close to the hoisting chain extending downwards and the hoisting hook. Because the electric crane provided by the invention has the limiting device arranged below the pulley, the potential safety hazards of the electric crane can be reduced through limiting the hoisting hook, and the limiting device is simple and compact in structure, and reliable and stable in operation.
Description
Technical field
The present invention relates to a kind ofly have the electronic of inhibiting device and hang.
Background technology
In the prior art, electronic hanging on is not provided with inhibiting device, when its hoisting operation, has potential safety hazard.
Summary of the invention
The purpose of this invention is to provide and a kind ofly have the electronic of inhibiting device and hang.
For achieving the above object, the technical solution used in the present invention is:
A kind of have the electronic of inhibiting device and hang, comprise vertical columns, one end is fixedly connected on the arm on the described vertical columns, engine installation, end away from described vertical columns of described arm is provided with pulley, described pulley is installed on the described arm by pulley base, the steel rope of being drawn by described engine installation extends downwards after walking around described pulley, described steel wire end is connected with suspension hook, end away from described vertical columns of described arm is provided with inhibiting device, described inhibiting device comprises the rotating spacing rotating shaft that is arranged on the described arm, be fixed on the limit switch of described spacing rotating shaft one end, one end is fixedly connected on also can be with the baffle ring of its coaxial rotation in the described spacing rotating shaft, be fixedly installed on the block of the described baffle ring other end, described block is near the steel rope and the suspension hook of described downward extension.
Preferably, described spacing rotating shaft is arranged on the described pulley base.
Preferably, an end that is connected with described block of described baffle ring is a horizontal shaft, and described block is socketed on the described horizontal shaft.
Preferably, described block is cylindrical.
Preferably, described baffle ring has a turning, and an end at described turning is fixedly connected in the described spacing rotating shaft, and the other end is horizontally disposed with.
Because the technique scheme utilization, the present invention compared with prior art has following advantage:
Because the present invention is provided with inhibiting device below pulley, can carry out spacingly by it to suspension hook, reduced electronic potential safety hazard of hanging, and this inhibiting device is simple in structure, compact, reliable in action, stable.
Description of drawings
Accompanying drawing 1 is the electronic front view that hangs with inhibiting device of the present invention;
Accompanying drawing 2 is the electronic A-A enlarged view that hangs with inhibiting device of the present invention.
In the above accompanying drawing: 1, vertical columns; 2, arm; 3, engine installation; 4, pulley; 5, pulley base; 6, steel rope; 7, suspension hook; 8, inhibiting device; 9, spacing rotating shaft; 10, limit switch; 11, baffle ring; 12, block.
The specific embodiment
Below in conjunction with embodiment shown in the drawings the present invention is further described:
Embodiment one: shown in accompanying drawing 1 and accompanying drawing 2.
A kind of have the electronic of inhibiting device and hang, comprise that vertical columns 1, an end are fixedly connected on arm 2, the engine installation 3 on the vertical columns 1, end away from vertical columns 1 of arm 2 is provided with pulley 4, pulley 4 is installed on the arm 2 by pulley base 5, walk around the extension downwards of pulley 4 backs by the steel rope 6 that engine installation 3 is drawn, steel rope 6 ends are provided with suspension hook 7;
End away from vertical columns 1 of arm 2 is provided with inhibiting device 8, inhibiting device 8 comprises the rotating limit switch 10 that is arranged on spacing rotating shaft 9 on the pulley base 5, is fixed on spacing rotating shaft 9 one ends, be fixedly connected in the spacing rotating shaft 9 and can be with the baffle ring 11 of its coaxial rotation, be fixedly installed on the block 12 of baffle ring 11 1 ends, baffle ring 11 has a turning, one end at turning is fixedly connected in the spacing rotating shaft 9, the other end is horizontally disposed with, one end of the level of baffle ring 11 is provided with the horizontal shaft of a vertical and baffle ring 11, and columniform block 12 is socketed on the horizontal shaft; Block 12 is near the steel rope 6 and the suspension hook 7 that extend downwards.
When suspension hook 7 is up, suspension hook 7 is run into block 12, block 12 drives baffle ring 11, spacing rotating shaft 9 and together upwards rotates, the straight-line motion of suspension hook 7 is converted to rotatablely moving of inhibiting device 8, because being arranged on the limit switch 10 of spacing rotating shaft 9 one ends together rotates with spacing rotating shaft 9, so its action is played position-limiting action with supply disconnecton; When suspension hook 7 is descending, under the action of gravity of block 12, inhibiting device 8 homings.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
