Description
Technical Field
The utility model belongs to the technical field of traffic equipment, a insulating subassembly that hangs is related to.
Background
Along with the continuous progress of science and technology, the development of urban rail transit is also more and more rapid, and the rigid overhead contact net system that electrified railway and urban rail transit used hangs and generally adopts busbar and the contact rail that have corresponding rigidity to constitute, in order to fix the busbar, makes the even current collection of pantograph, carries out the centre gripping through insulating suspension assembly to the busbar.
Because the bus bar is influenced by the materials of the bus bar and the working state of the bus bar, the bus bar can expand with heat and contract with cold, the existing insulating suspension assembly is fixed on the rigid overhead contact rail, and the insulating suspension assembly and the bus bar are clamped tightly, so that the bus bar can not move relative to the insulating suspension assembly when in use, the clamping stagnation condition of a wire clamp on the insulating suspension assembly can occur when the bus bar expands with heat and contracts with cold, the looseness easily occurs in the connection of the bus bar and the electric wire on the electric car, the operation of the electric car is influenced, and the bus bar is required to be maintained frequently.
Disclosure of Invention
The utility model aims at having the above-mentioned problem to current technique, provided an insulating subassembly that hangs, the utility model aims to solve the technical problem that: how to avoid clamping stagnation when the bus bar moves.
The purpose of the utility model can be realized by the following technical proposal:
the utility model provides an insulating subassembly that hangs, includes the connecting rod that can press from both sides tight fastener of busbar, the insulator of being connected with the fastener and be connected with the insulator, its characterized in that, the cover is equipped with adjusting sleeve on the connecting rod, the connecting rod can be at adjusting sleeve internal rotation, adjusting sleeve is worn out to the one end of connecting rod, should serve and be equipped with the dog that enables this end and stretch out adjusting sleeve all the time.
The working principle is as follows: by sleeving the adjusting sleeve on the connecting rod, the connecting rod can rotate in the adjusting sleeve, and the stop block can limit the connecting rod, so that the connecting rod can be hung at the end part of the adjusting sleeve, when the heat of the busbar arranged on the wire clamp expands and contracts, the busbar can move on the wire clamp and is blocked with the wire clamp, so that the busbar is blocked with the wire clamp, and through the arrangement of the adjusting sleeve, the connecting rod and the stop block on the connecting rod, the connecting rod can rotate in the adjusting sleeve, the end part of one end of the connecting rod is always extended out of the adjusting sleeve through the limiting action of the stop block, the connecting rod is hung on the adjusting sleeve through the stop block, the bus bar can rotate in the circumferential direction, so that the bus bar can be adjusted in the wire clamp, thereby avoided busbar and the dead condition of fastener card to appear, and then the jamming appears when having avoided meeting busbar drunkenness.
In the insulating suspension assembly, the adjusting sleeve is sleeved with the adjusting hanging plate, and the adjusting sleeve is in threaded connection with the adjusting hanging plate.
The setting of this structure for adjusting sleeve's connection is simpler, and to the convenience more of the regulation of connecting rod, be difficult for receiving the interference of other parts when adjusting, thereby has improved the convenience that insulating suspension assembly set up.
In the above-mentioned insulating suspension assembly, the connecting rod is sleeved with two gaskets, one of the gaskets is located between the adjusting sleeve and the stop block, and the other gasket is located between the insulator and the adjusting sleeve.
Because when insulating suspension assembly used, the connecting rod probably takes place to reciprocate, has consequently add two gaskets, reduces the wearing and tearing between connecting rod and adjusting sleeve and connecting rod and the insulator, has prolonged insulating suspension assembly's life.
In the insulating suspension assembly, the connecting rod is provided with an external thread, the stop block is a nut, and the nut is in threaded connection with the connecting rod.
The setting of this structure for being connected convenient and fast more between dog and the connecting rod, the realization that simultaneously also can be quick is stretched out adjusting sleeve's length to the connecting rod and is adjusted, thereby has improved the practicality of insulating subassembly that hangs.
In the insulating suspension assembly, the adjusting hanging plate is connected with the contact rail through a bolt, and a limiting fixed sheet is arranged between the bolt and the adjusting sleeve.
The setting of this structure for can keep apart between adjusting the link plate and the adjusting sleeve, thereby make adjusting sleeve's use more stable, also can be stable with adjusting sleeve and adjust the link plate and be connected, thereby improved adjusting sleeve's stability of connecting.
Compared with the prior art, the insulating suspension assembly has the following advantages: present is to hang subassembly and contact rail lug connection with insulating, and the busbar is pressed from both sides tightly by the fastener this moment, has leaded to the busbar can appear the jamming phenomenon when expend with heat and contract with cold, and the present case is through connecting rod, dog and adjusting sleeve's setting for insulating subassembly that hangs can hang and set up in adjusting sleeve, thereby has avoided the phenomenon that the busbar appears jamming, has improved the stability in use of busbar.
