Embodiment Construction

[0036] The contact line grinder for rigid catenary of the present invention includes a trolley mechanism 10 , a grinding mechanism 20 , an angle adjustment mechanism 30 , a control mechanism 40 , a pressure supply station 50 and a power supply 60 . The pressure supply station adjusts the pressing force of the grinding mechanism on the contact line 702 under the action of the control mechanism; the angle adjustment mechanism adjusts the grinding angle of the grinding mechanism according to the degree of wear of the contact line of the rigid suspension catenary 70 .

[0037] The trolley mechanism 10 includes a side plate assembly, a support beam 105, a suspension running assembly and a V-groove running assembly. The suspension running assembly rolls on the upper end surface of the bus bar 701, and the V-groove running assembly fits on the lower end surface of the bus bar.

[0038] The suspension traveling assembly includes a suspension traveling wheel 103 and a suspension traveli...

Abstract

The invention discloses a contact line grinding machine of a rigid contact net. The grinding machine comprises a walking trolley mechanism, a grinding mechanism, an angle adjusting mechanism, a control mechanism, a pressure supply station and a power source. The pressure supply station adjusts the pressing force of the polishing mechanism on the contact line under the action of the control mechanism; the angle adjusting mechanism adjusts the grinding angle of the grinding mechanism according to the abrasion degree of the contact line. The angle adjusting mechanism comprises at least one angle adjusting unit. Each angle adjusting unit comprises a grinding unit fixing frame, an angle adjusting supporting piece, a guide rail assembly and a pressure cylinder. A fixing point is arranged on the angle adjusting supporting piece, an arc-shaped sliding groove is formed in the lower end of the angle adjusting supporting piece, and the grinding unit fixing frame and the angle adjusting supporting piece are locked after the grinding unit fixing frame slides to a set angle in the arc-shaped sliding groove with the fixing point as the circle center. A polishing sheet of the polishing mechanism polishes a sharp corner formed by the end face of the contact line and the outer arc face and the abrasion plane of the contact line. The device is high in automation degree, high in grinding efficiency and good in grinding effect.

Description

technical field [0001] The invention relates to a contact wire grinder in the technical field of urban rail power supply, in particular to a contact wire grinder for a rigid catenary. Background technique [0002] In the rail transit power supply system, the rigid catenary is one of the main traction power supply methods. The rigid catenary is the overhead rigid suspension bus bar system, which clamps the contact wire in the bus bar, and the locomotive directly contacts the contact wire through the pantograph. A power supply method for urban rail transit. This system is mainly used for power supply in tunnels, stations, and passages under bridges. Compared with the traditional overhead flexible catenary, it has stronger current-carrying capacity, no risk of disconnection, high safety and reliability, fewer parts, easy installation, and simple maintenance. It has a series of advantages such as low maintenance cost, reduced tunnel clearance, and saved civil construction inves...
