Fitting is fixedly connected with suspension base rear end by bolt pair II, and the suspension pulley is hinged on outstanding by guide roller frame and pin shaft
Hang the lower section of pan frontward end；
The metal regulating part is matched by arch adjustable plate with the arcuate surfaces of arcuate base front end, and arch adjustable plate
Two sides are symmetrically arranged with bar shaped mounting hole, and the bolt pair I passes through bar shaped mounting hole and locks with the matched arch of arch adjustable plate
Metal regulating part is fixed in arcuate base by cushion block suit, and arch adjustable plate can adjust established angle by bar shaped mounting hole
Degree, and then adjust the mounting height of suspension pedestal.
Anti-slop serrations are transversely equipped in the arcuate outer surface of the arcuate base front end.
The suspension pedestal leading portion is door shaped stent, and door shaped stent two sides are symmetrically arranged with one group of adjustment hole, the pin shaft
The position that guide roller frame is inlaid on door shaped stent is adjusted by the position being hinged on one group of adjustment hole.
The guide roller frame is equipped with spacer pin, and spacer pin is located at the top of suspension pulley.
Compared to the prior art, the utility model has the advantages that
1) there was only pulley swing, remaining part in the device when pantograph is lifted, swings up and down in online road transport row
Part is rigid connection, improves the stability of carrier cable suspension；And reasonable stress, guarantee the integral strength of device.
2) contact surface between arcuate base and composite insulator is arcwall face, can need to adjust matching for the two according to route
Close angle degree guarantees suspension height and the clearance for insulation requirement of carrier cable；Arcuate base front end arch surface is equipped with anti-slop serrations, makes to connect
Connect robust；Carrier cable uppermost limit pin effectively limits its vertical displacement, prevents carrier cable from slipping, and ensure that traffic safety.

Specific embodiment
The utility model is described in detail in 1-4 and specific embodiment with reference to the accompanying drawing.
A kind of low clearance single-track tunnel carrier cable suspension arrangement, including arcuate base 1, composite insulator 2, suspension pedestal 3,
Suspension pulley 4, the arcuate base 1 are fixed in tunnel wall by anchor bolt, and after 1 front end of arcuate base and composite insulator 2
The metal regulating part 8 at end is fixedly connected by bolt pair I 5, after 2 forward metal connector 9 of composite insulator and suspension pedestal 3
End is fixedly connected by bolt pair II 6, and the suspension pulley 4 is hinged on suspension 3 front end of pedestal by guide roller frame 10 and pin shaft 7
Lower section；
The metal regulating part 8 is matched by arch adjustable plate 12 with the arcuate surfaces of 1 front end of arcuate base, and arch tune
Section 12 two sides of plate are symmetrically arranged with bar shaped mounting hole 13, the bolt pair I 5 pass through bar shaped mounting hole 13 and with arch adjustable plate 12
Metal regulating part 8 is fixed in arcuate base 1 by the arch locking suit of cushion block 17 matched, and arch adjustable plate 12 can pass through item
Shape mounting hole 13 adjusts setting angle, and then adjusts the mounting height of suspension pedestal 3.Outside the arch of 1 front end of arcuate base
It is transversely equipped with anti-slop serrations 11 on surface, increases the frictional force of metal regulating part 8 and arcuate base 1, enhances the stability of connection.
