Abstract
The utility model discloses a power supply system of a crane, which comprises the crane, a first trolley conductor and a first contactor. The first contactor supplies power to the crane through the first trolley conductor. The power supply system of the crane further comprises a second trolley conductor and a second contactor, the second contactor is connected with the crane through the second trolley conductor and supplies power to the crane. Another power supply line can be provided to continue supplying power to the crane timely when one power supply line for supplying power to the crane fails, and accordingly potential safety hazards caused by power outage of the crane are eliminated.
Description
Technical field
The utility model relates to a kind of slide wire power supply structure, relates in particular to a kind of hoisting crane electric power system of using trolley.
Background technology
Safety sliding contact line is a kind of " the special electric wire " that power supply is provided for mobile device (mainly being driving, crane).
The power-supply trolley line apparatus is made up of conduit, two major parts of current collector and some accessory parts.
1, conduit: being semi-enclosed shape tubular part of leading, is the base portion of trolley.Its inside as required the high 3-16 root of embedding nude guide rail as electric power conductor, mutually insulated between each guide rail, thus guarantee the safety of power supply.And when hotline maintenance, prevent the service personnel electric shock accidents effectively.Every length of conduit that the our factory produces is 4m, and can connect into needs length arbitrarily, and common conduit is made into linear, also can process circular arc etc. by specific demand.
2, current collector is the one group of brush shell frame that in conduit, moves; Drive by being placed in the shift fork on the electrical mechanisms (driving, dolly, electric block etc.) (or conduction chain etc.); Make it and use electrical mechanisms synchronized operation, will be through guide rail, public electrical motor or other control elements of arriving of the electric energy of brush.The number of poles of current collector brush has the 3-16 utmost point corresponding with conduit middle guide number of poles.
Existing hoisting crane is supplied power through trolley by single power supply, if et out of order then can stop the work of hoisting crane, can only be after waiting for maintenance, and hoisting crane just can work on, and causes time cost to rise; And may there be potential safety hazard in hoisting crane because outage quits work.
The utility model content
When being the hoisting crane power supply, because fault causes stopping to make hoisting crane quit work to the hoisting crane power supply that cause the technical matters of potential safety hazard, the utility model adopts following technical scheme for solving above-mentioned prior art:
A kind of hoisting crane electric power system; Comprise bonded assembly hoisting crane, first trolley and first contactless switch successively; First contactless switch is supplied power to hoisting crane through first trolley; Said hoisting crane electric power system also comprises second trolley and second contactless switch, and second contactless switch is connected with hoisting crane through second trolley, and supplies power to hoisting crane.
Further, described a kind of hoisting crane electric power system also comprises first switch, and first switch is arranged between first trolley and the hoisting crane.
Further, described a kind of hoisting crane electric power system also comprises second switch, and second switch is arranged between second trolley and the hoisting crane.
Further, described a kind of hoisting crane electric power system also comprises the 3rd trolley and the 3rd contactless switch, and the 3rd contactless switch is connected with hoisting crane through the 3rd trolley, and supplies power to hoisting crane.
Further, first trolley and second trolley are installed in the same side of the support rail beam of hoisting crane, for the levels balance is installed.
The beneficial effect of the utility model is:
Hoisting crane in the utility model technical scheme has a plurality of supply lines, when for a supply line et out of order of hoisting crane power supply, an other supply line is provided, and continues and in time is hoisting crane power supply, the potential safety hazard that the elimination hoisting crane causes because of outage.
Description of drawings
Fig. 1 is the embodiment module diagram of a kind of hoisting crane electric power system of the utility model.
The specific embodiment
Specify the preferred embodiment of the utility model below in conjunction with accompanying drawing.
See also Fig. 1, it is the embodiment module diagram of a kind of hoisting crane electric power system of the utility model.
A kind of hoisting crane electric power system of the utility model, it comprises: hoisting crane 10, first trolley 11, first contact, 12, first switch 13, second trolley 21, second contactless switch 22 and second switch 23.Wherein, hoisting crane 10, first trolley 11 and first contactless switch 12 are connected successively, and hoisting crane 10, second trolley 21 and second contactless switch 22 are connected successively.First switch 13 is arranged between first trolley 11 and the hoisting crane 10.Second switch 23 is arranged between second trolley 21 and the hoisting crane 10.
First contactless switch 11 is supplied power to hoisting crane 10 through first trolley 12.
Second contactless switch 21 is connected with hoisting crane 10 through second trolley 22, and to hoisting crane 10 power supplies.
First contact, 12 and second contactless switch 22 is installed in the cart electronic box of hoisting crane.The cart electronic box is on cart is walked on stage.
The principle of work of the utility model is following:
Certainly, a kind of hoisting crane electric power system of the utility model can also comprise the 3rd trolley and the 3rd contactless switch, and the 3rd contactless switch is connected with hoisting crane through the 3rd trolley, and supplies power to hoisting crane.
Compared to prior art; Hoisting crane in the utility model technical scheme has a plurality of supply lines, when for a supply line et out of order of hoisting crane power supply, an other supply line is provided; Continue and in time be hoisting crane power supply, the potential safety hazard that the elimination hoisting crane causes because of outage.In addition, the utility model technical scheme is simple, is prone to realize.
Here description of the utility model and application is illustrative, is not to want the scope of the utility model is limited in the above-described embodiments.Here the distortion of the embodiment that is disclosed and change are possible, and the replacement of embodiment is known with the various parts of equivalence for those those of ordinary skill in the art.Those skilled in the art are noted that under the situation of spirit that does not break away from the utility model or essential characteristic, and the utility model can be with other form, structure, layout, ratio, and realize with other assembly, material and parts.Under the situation that does not break away from the utility model scope and spirit, can carry out other distortion and change here to the embodiment that is disclosed.
