Abstract
The utility model discloses a kind of hoisting crane electromagnetic disc device, its structure is: electromagnetic disc is provided with head-rope, and head-rope is connected to the suspension hook on hoisting crane by round-link chain.Electromagnetic disc is provided with access cable, access cable one end is connected in electromagnetic disc, and the other end is connected to quick coupling.The side outer wall of whip-gin group is fixed with switch case, is provided with switch in described switch case, switch ends is connected to supply cable and quick coupling respectively.Because quick coupling after cut-off switch is not charged, even if the non-power-off of power end or quick coupling breakage, operating personnel directly extracts quick coupling also can not there is Danger Electric shock risk, improves the safety of device.
Description
Technical field
The utility model relates to a kind of hoisting crane load-engaging device, refers to a kind of hoisting crane electromagnetic disc device especially.
Background technology
Electromagnetic disc is one of most important load-engaging device of crane.Be widely used in the magnetic material such as steel scrap, blank and have bad luck work.In practical work process, electromagnetic disc round-link chain hangs under suspension hook, completes the operating process that electromagnetic disc obtains magnetic material, degaussing blowing.
Existing hoisting crane electromagnetic disc provides direct supply by rectify control cabinet in crane girder casing, is connected by quick coupling by cable with electromagnetic disc.Direct current (DC) is sent into electromagnetic disc coil winding by cable.When electromagnetic disc drops on the material by handling, in electromagnetic disc, the magnetic flux of electromagnet is closed by article by the shell of electromagnet, produces electromagnetic attraction, and till remaining to power-off always.
But in ongoing operations process, crane, except with except magnetic chuck absorbing material, also takes into account other weight of handling.Now manually must lay down electromagnetic disc, and unload quick coupling.Under open work environment, the inclement weather such as to expose to the sun and rain easily causes quick coupling tracking, directly extract quick coupling in the energized state may cause electric shock accidents if Ground Operation personnel and crane operator room are not carried out and confirmed (the non-power-off of driver or ground staff's awareness of safety not strong), pose great risks.
There is following shortcoming in prior art: easily electric shock accidents occurs, poor stability.
Summary of the invention
The purpose of this utility model is to provide a kind of and electric shock accidents, hoisting crane electromagnetic disc device that safety is good not easily occurs.
For achieving the above object, hoisting crane electromagnetic disc device designed by the utility model, the supply cable comprising electromagnetic disc and be connected with external power supply, electromagnetic disc is provided with access cable and the head-rope being connected hoisting crane, and supply cable is connected by quick coupling with access cable.Also comprise switch case and switch, switch case is fixed in the fender plane of whip-gin group, and switch is fixed in switch case, and switch ends is connected to supply cable and quick coupling respectively.During field operation, as need power-off disk be unloaded, can first cut-off switch, then extract quick coupling.
Preferably, described switch selectable knife-like switch, sky are opened or button switch.When selecting button switch, the button switch with instruction on off mode signal lamp also can be selected.
The beneficial effects of the utility model are: cable is connected on the switching device in whip-gin group, reduce that cable is wound around, damaged and quick coupling is involved the probability of disconnection by wire, improve safety; After cut-off switch, quick coupling is not charged, even if the non-power-off of power supply or quick coupling breakage, operating personnel directly extracts quick coupling also Danger Electric shock risk can not occur, and further increases safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model hoisting crane electromagnetic disc device.
Wherein: electromagnetic disc 1, supply cable 2, access cable 3, head-rope 4, quick coupling 5, switch case 6, switch 7, whip-gin group 8, suspension hook 9, round-link chain 10
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Be illustrated in figure 1, the utility model hoisting crane electromagnetic disc device, electromagnetic disc 1 is provided with head-rope 4, and head-rope 4 is connected to the suspension hook 9 on hoisting crane by round-link chain 10.Electromagnetic disc 1 is provided with access cable 3, access cable 3 one end is connected in electromagnetic disc 1, and the other end is connected to quick coupling 5.The fender plane of whip-gin group 8 is fixed with switch case 6, is provided with switch 7 in switch case 6, switch 7 two ends are connected to supply cable 2 and quick coupling 5 respectively.
