Description
Technical Field
The utility model belongs to the technical field of urban rail transit rigid suspension power supply system, concretely relates to rotatable formula busbar positioning wire clamp.
Background
The rigid suspension power supply system for urban rail transit is characterized in that a busbar is vertically suspended above a line by adopting a busbar positioning wire clamp, a contact line is clamped by the busbar, and a pantograph draws current through the contact line. The existing bus bar positioning wire clamp (patent number: 201420450581.4) is installed on a wrist arm through a U-bolt, cannot rotate along with free sliding of a bus bar, is easy to cause clamping stagnation of the bus bar in an environment with large temperature change, causes arc discharge when a pantograph is scratched, and affects driving safety.
SUMMERY OF THE UTILITY MODEL
The utility model provides a rotatable formula busbar location fastener has overcome the not enough of prior art, has guaranteed driving safety.
The utility model adopts the technical proposal that: the utility model provides a rotatable formula busbar location fastener, includes staple bolt, lower staple bolt, location fastener, it connects under on the staple bolt to go up the staple bolt, the location fastener hangs on establishing the locating pin nail of staple bolt below under, and the location fastener can be rotatory around the dowel.
The lower hoop and the positioning pin are of an integrated structure.
The center of the lower hoop is provided with a step hole II, and the positioning pin is inserted into the step hole II.
The positioning wire clamp is formed by connecting two wire clamp bodies which are symmetrically arranged through a bolt pair III, and the two wire clamp bodies are sleeved on the positioning pin nail through a step hole I formed in a joint surface of the two wire clamp bodies.
Go up staple bolt and lower staple bolt one side and pass through pin articulated connection, the opposite side passes through I connection of bolt pair.
The upper anchor ear is connected with the two sides of the lower anchor ear through a bolt pair II.
Compared with the prior art, the utility model discloses beneficial effect who has:
1) the upper anchor ear and the lower anchor ear can be tightly adhered to the wrist arm, so that the mounting precision is high, and the mounting is convenient and quick;
2) the lower hoop is hinged with the positioning wire clamp through a pin, so that the positioning wire clamp can rotate freely, and clamping stagnation of the busbar is prevented. The problem that the confluence heat is free to expand and contract and the driving safety is guaranteed in an environment with large temperature change is solved.
