Abstract
The utility model relates to a sliding contact line of an aluminum-matrix steel conductor. The sliding contact line is characterized by being integrally manufactured by compounding an aluminium bracket and a stainless steel conductive plate, wherein the aluminium bracket acts as an electric conductor, the stainless steel conductive plate is inserted and fixed on the top of the aluminium bracket, and the stainless steel conductive plate is in contact with parallel plate surfaces of a current collector. The sliding contact line of the aluminum-matrix steel conductor is used for power transmission of large-tonnage hoisting equipment of industrial and mining enterprises, and is used for providing an operating track of a current collector, and has the advantages of compact structure, high strength, large current collection contact area, stable operation, reliable power transmission, large carrying capacity, light weight, low cost, concealed and safe arrangement, flexible and convenient installation and the like.
Description
Technical field
The utility model relates to a kind of trolley of the large-tonnage hoisting equipment electric power transfer for industrial and mining enterprises, and specifically aluminium base steel conductor slipping contact wire belongs to the power supply facilities technical field.
Background technology
In the prior art, the trolley that is used for the large-tonnage hoisting equipment electric power transfer of industrial and mining enterprises normally adopts base steel copper conductor trolley (shown in Figure 2), it is combined into by steel bracket 3 and copper conductor 4, and mainly there is following problems in this trolley: copper conductor 4 is little with the current collector contact area; Add man-hour and steel bracket 3 faying face Xiao Yi; Because copper material is different from the thermal coefficient of expansion of steel matter after being subjected to electricity, cause easily their faying face loosening, affect working strength; And copper product is relatively more expensive, and use cost is higher.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of aluminium base steel conductor slipping contact wire is provided, it is used for the electric power transfer of the large-tonnage hoisting equipment of industrial and mining enterprises, as providing the current collector orbit to use, have compact conformation, intensity high, be subjected to electric interface large, operate steadily, transmit electricity reliable, ampacity is large, lightweight, cost is low, arrange the advantages such as hidden safe, convenient and flexible installation.
The technical scheme that provides according to the utility model: aluminium base steel conductor slipping contact wire, it is characterized in that: it is to be complex as a whole by aluminum frame and stainless steel conductive plate to make, described aluminum frame is as electric conductor, the stainless steel conductive plate is mounted in the aluminum frame top, and the stainless steel conductive plate contacts with current collector parallel-plate face.
As further improvement of the utility model, described aluminum frame is I-shaped structure.
As further improvement of the utility model, described aluminum frame top surface is provided with the splayed die cavity, described stainless steel conductive plate is long flat shape, and the both sides bending of stainless steel conductive plate and the interior also roll extrusion of splayed die cavity that is embedded on the aluminum frame top surface are integrated.
The utility model compared with prior art, advantage is:
(1) aluminium base steel conductor slipping contact wire of the present utility model adopts aluminum to make aluminum frame, has lightweight, low cost and other advantages; Described aluminum frame is I-shaped structure, and structural strength is high, can flexural deformation; Described aluminum frame top is embedded with the stainless steel conductive plate, because stainless steel conductive plate and current collector parallel-plate face contact area are large, operates steadily, and can tolerate large short-circuit impact electric current; Described aluminum frame is as electric conductor, and ampacity is large, and current class can reach 500A ~ 3000A, and electric pressure can reach 3KV, and conductance is good, can reduce the electric energy loss on the circuit.
(2) the stainless steel conductive plate is embedded in the splayed die cavity on the aluminum frame and roll extrusion is integrated, in use needn't worry to occur to occur the phenomenons such as loosening or displacement between stainless steel conductive plate and the aluminum frame because material is affected by the rear thermal expansion coefficient difference of electricity, transmission operation is reliable.
(3) aluminium base steel conductor slipping contact wire is the single-phase layout of laying, and is not subjected to the interference of the Electric and magnetic fields of other phase buses, arranges hidden safe, convenient and flexible installation; Aluminium base steel conductor slipping contact wire can use in characteristics such as high temperature, many dirt places, can substitute existing base steel copper conductor trolley fully, and laying installation substitutes it, and can be used widely.
Description of drawings
Fig. 1 is the structural representation of aluminium base steel conductor slipping contact wire of the present utility model.
Fig. 2 is the structural representation of existing base steel copper conductor trolley.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1, aluminium base steel conductor slipping contact wire of the present utility model mainly is to be complex as a whole by aluminum frame 1 and stainless steel conductive plate 2 to make, described aluminum frame 1 is as electric conductor, and stainless steel conductive plate 2 is mounted in aluminum frame 1 top, and stainless steel conductive plate 2 contacts with current collector parallel-plate face.
Because stainless steel conductive plate 2 is large with current collector parallel-plate face contact area, operates steadily, and can tolerate large short-circuit impact electric current.Owing to be directly to adopt aluminum frame 1 as electric conductor, ampacity is large, and current class can reach 500A ~ 3000A, and electric pressure can reach 3KV, and conductance is good, can reduce the electric energy loss on the circuit.
As shown in Figure 1, described aluminum frame 1 is I-shaped structure, and structural strength is high, can flexural deformation.
As shown in Figure 1, described aluminum frame 1 top surface is provided with the splayed die cavity, and described stainless steel conductive plate 2 is long flat shapes, and the both sides bending of stainless steel conductive plate 2 and the interior also roll extrusion of splayed die cavity that is embedded on aluminum frame 1 top surface are integrated.So in use just needn't worry to occur to occur the phenomenons such as loosening or displacement between stainless steel conductive plate 2 and the aluminum frame 1 because material is affected by the rear thermal expansion coefficient difference of electricity, transmission operation is reliable.
The single-phase layout of laying of aluminium base steel conductor slipping contact wire of the present utility model is not subjected to the interference of the Electric and magnetic fields of other phase buses; In conjunction with the hidden layout feed trend in power consumption equipment position, convenient and flexible installation; Aluminium base steel conductor slipping contact wire of the present utility model can use in characteristics such as high temperature, many dirt places, can substitute existing base steel copper conductor trolley fully, and laying installation substitutes it, and can be used widely.
