Abstract
The utility model discloses a current collector of a mobile power supply device of a portal cane, which comprises a roller wheel (1), an insulating electric brush bracket (2), a support wheel axle (3) and a bearing (8), wherein a stainless steel roller wheel is used as the roller wheel (1); the roller wheel (1) contacts with an electric brush (6) that is connected with a cable (7); one side of the electric brush (6) contacts with the roller wheel (1), and the other side of the electric brush (6) is compressed by a spring (4); the electric brush (6) is fixed in the insulating electric brush bracket (2); and two stainless steel roller wheels are adopted by each current collector. By adopting the technical scheme, the current collector has the advantages of being simple in structure, simple and convenient to install and maintain, safe and reliable, low in construction cost and the like, and has good promotion and practical values.
Description
Technical field
The utility model relates to a kind of transfer crane mobile power supply device, relates in particular to a kind of current colector of transfer crane mobile power supply device.
Background technology
Existing transfer crane complete machine mobile power supply device generally adopts slide wire power supply, orbit along whole hoisting crane lays naked cable (title slip), current colector is housed on hoisting crane, current colector slides or rolls along slip, power supply is introduced, the slip that uses is circular copper wire or cucurbit copper cash at present, and laid down cost is quite high; In order to save cost, the contriver once autonomous Design a kind of with steel cored aluminum stranded wire as slip, make current colector with the copper pulley, introduce power supply from the axle of copper pulley, but the contact position spark is serious, aluminum stranded conductor and copper pulley all are easy to wear and tear, the fault rate height, service life weak point.
Summary of the invention
The technical problems to be solved in the utility model is: make current colector with the copper pulley, when the axle of copper pulley was introduced power supply, the contact position spark was serious, and aluminum stranded conductor and copper pulley all are easy to wearing and tearing, build and the maintenance cost height, the fault rate height, service life weak point problem.A kind of current colector of transfer crane mobile power supply device is provided.
The utility model is achieved by following technical proposals:
A kind of current colector of transfer crane mobile power supply device, it comprises roller, and the insulated electro brush holder supports wheel shaft and bearing, and described roller is the corrosion-resistant steel roller.
Roller contacts with brush, connects cable behind the brush.
Brush one side contacts roller, opposite side is by spring application.
Brush is fixed in the insulated electro brush holder.
Each current colector adopts two corrosion-resistant steel rollers.
According to the technical solution of the utility model, adopt the corrosion-resistant steel roller to do current colector, reduced laid down cost; Roller contacts with brush, connects cable behind the brush, avoids electric current to pass through the service life that bearing reduces bearing, has reduced maintenance cost; Brush one side contacts roller, opposite side are contacted closely roller by spring application with brush, conduction is reliable; Brush is fixed in the insulated electro brush holder, and not only insulation also has water-proof function, prevents that rainwater from entering the mating surfaces of brush and corrosion-resistant steel roller and reducing practical life; Each current colector adopts two corrosion-resistant steel rollers, and area of contact is big, and electric conductivity is good, is difficult for the cap spark, has prolonged the equipment practical life.Therefore, the utlity model has simple in structure, installation and maintenance are easy, safe and reliable, preceence such as laid down cost is low, and excellent popularization and practical value are arranged.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the External view of Fig. 1.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.
Embodiment
As depicted in figs. 1 and 2, each current colector is arranged side by side by the corrosion-resistant steel roller 1 of two band grooves, area of contact is big, and electric conductivity is good, is difficult for the cap spark, cost is low, avoided because of spark causes the aluminum stranded conductor spot corrosion, steel cored aluminum stranded wire and corrosion-resistant steel roller 1 rolling touch pass to electric energy the corrosion-resistant steel roller 1 of current colector from steel cored aluminum stranded wire, with brush 6 electric energy is derived from corrosion-resistant steel roller 1 simultaneously, avoid electric current to pass through the service life that bearing reduces bearing.Corrosion-resistant steel roller 1 is fixed between bench insulator 10 and the insulated electro brush holder 2 by bearing 8 and support wheel shaft 3 usefulness nuts 9 respectively, bench insulator 10 and insulated electro brush holder 8 can be used the nylon 1010 material, they are fixed on the current colector base 11 by flange, brush 6 reliably contacts with corrosion-resistant steel roller 1 side with spring perch 5 by spring 4, guarantee that electric current passes through smoothly, wherein insulated electro brush holder 2 has water-proof function, prevents that rainwater from entering brush 6 and reducing practical life with the mating surfaces of corrosion-resistant steel roller 1.
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
