Abstract
The utility model discloses a roller-rotating type abrasion-resistant pantograph for an electric locomotive. The roller-rotating type abrasion-resistant pantograph comprises a base and a frame body, wherein a fixed frame is arranged on the base, and the middle of the fixed frame is provided with a rotary shaft; the lower end of the frame body is installed on the fixed frame through the rotary shaft, and the upper part of the frame body is provided with a cross pull rod; the cross pull rod is connected with a tension plate through a pantograph rising spring; and the upper end of the frame body is provided with a conductive rotary roller. The roller-rotating type abrasion-resistant pantograph adopts a conductive rotary roller structure, the sliding friction of the pantograph in the prior art and a conductive cable is changed into rolling friction, and the abrasion of the pantograph is greatly reduced. The roller-rotating type abrasion-resistant pantograph has the advantages of simple structure, simplification and convenience in implementation, smooth and reliable contact with the cable and stable work, and avoids the conditions that a support is damaged or a bolt is broken. The bow head of a stringing bow is uniformly contacted with a contact wire, and the electric locomotive is not easily tripped and is not easy to generate electric arcs when the electric locomotive runs. The service life is long, and the maintenance and the replacement are convenient.
Description
Technical field
The utility model belongs to electric locomotive power receiving equipment technical field, be specifically related to a kind of simple in structure, simple installation, work safety, the rotatable anti scuffing collector bow of the electric locomotive used roller of long service life.
Background technology
The support of the motor vehicle frame collector bow of prior art is set to diamond structure, collector bow bow and wire are sliding friction, because sliding friction power is larger, the rhombus support often occurs and hung situation bad or that latch breaks, in addition, it is inhomogeneous that sliding friction causes the collector bow bow to contact with wire, bow is pulled out a large amount of electric arcs when causing the electric locomotive operation, finally cause the generation of tripping, therefore bow collector of electric locomotive bow and wire also cause serious abrasion, and greatly reduce service life.For this reason, develop a kind of simple in structurely, be easy to implement, working stability is reliable, and the rotatable anti scuffing collector bow of the electric locomotive used roller of long service life is very important.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and is easy to implement, and working stability is reliable, the rotatable anti scuffing collector bow of the electric locomotive used roller of long service life.
The purpose of this utility model is to realize like this, comprise base and support body, on the described base fixed mount is set, described fixed mount middle part arranges rotating shaft, described support body lower end is installed on the fixed mount by rotating shaft, support body top arranges intermediate rod, and described intermediate rod is connected with support brace by the rising bow spring, and the support body upper end arranges the conduction transfer roller.
The utility model adopts conduction transfer roller structure, and it is friction of rolling that realization has the collector bow of technology and the cliding friction of cable, greatly reduces the wearing and tearing of collector bow.The utility model is simple in structure, be easy to implement, contact smooth-going reliable with cable, working stability is avoided support to be hung situation bad or that latch breaks and is occured, and stringing bow bow contacts with contact wire evenly, in electric locomotive when operation, be difficult for causing the generation of tripping, be difficult for producing electric arc, long service life, maintenance and replacing are convenient.

Among the figure: the 1-base, the 2-fixed mount, the 3-collets, the 4-rotating shaft, 5-support body, 6-intermediate rod, 7-insulcrete, 8-conduct electricity transfer roller, 9-support brace, 10-rising bow spring, 11-backguy guide roller, 12-backguy.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described, but never in any form the utility model is limited, any conversion or improvement based on the utility model training centre is done all fall into protection domain of the present utility model.
As shown in Figure 1, the utility model comprises base 1 and support body 5, on the described base 1 fixed mount 2 is set, described fixed mount 2 middle parts arrange rotating shaft 4, described support body 5 lower ends are installed on the fixed mount 2 by rotating shaft 4, support body 5 tops arrange intermediate rod 6, and described intermediate rod 6 is connected with support brace 9 by rising bow spring 10, and support body 5 upper ends arrange conduction transfer roller 8.
Described support body 5 top K/UPs in obtuse angle, angle is 135 ~ 180 °.
Described support body 5 respectively with affixed cooperation of rotating shaft 4 two ends.
Described conduction transfer roller 8 is by the cross bar socket normal-running fit of support body 5 upper ends.
The setting that is the level of state of described conduction transfer roller 8, perpendicular with the vertical pole of support body 5.
Described conduction transfer roller 8 two ends arrange respectively insulcrete 7.
Described intermediate rod 6 is perpendicular with the vertical pole of support body 5, and affixed cooperation.
2 rising bow springs 10 are set between described intermediate rod 6 and the support brace 9 at least.
Described rising bow spring 10 is symmetricly set between intermediate rod 6 and the support brace 9.
Connect on the described intermediate rod 6 and adjust backguy 12, described backguy 12 is walked around guide roller 11 and is connected to fixed mount one side.
Described base 1 is by collets 3 Connection Brackets 2.
Described fixed mount 2 is dihedral steel or cast steel structure.
Principle of work of the present utility model and working process:
The utility model adopts the structure that the conduction transfer roller is set in the support body upper end, so that form friction of rolling between collector bow and the cable, greatly reduce friction drag, the conduction transfer roller can be along with rotating with the moving contact of cable, effectively alleviate the wearing and tearing of collector bow, reached the purpose of anti scuffing.Because the utility model contacts smooth-going reliable with cable, be difficult for pulling out electric arc, not only avoided support to be hung situation bad or that latch breaks tripping operation and the impaired situation of cable itself in the time of also can not causing the electric locomotive operation occur, prolong service life, and maintenance and change more easy.
