Background technology
At present, the pantograph of rail traffic vehicles application is roughly divided into spring pantograph and air spring type pantograph two
Kind.Because air spring type pantograph has good followability, lightweight, manufacture and maintenance cost are low, overhaul the reason such as convenient,
Chinese high ferro, motor-car, locomotive all use air spring pantograph instead with pantograph, the urban track traffic such as subway, light rail also by
Step is using air spring type pantograph as development trend.
But, existing air spring type pantograph, when driving pantograph to rise, is to enter empty by compressed air
Gas spring, air spring expansion drives steel wire rope to act on underarm cam.This device needs steel wire rope or chain to transmit drawing when working
, easily there are the phenomenons such as eccentric wear, stranded, de- groove in power.
The content of the invention
It is an object of the invention to provide a kind of current collecting bow lifting device, using air spring, reliable operation, regular maintenance are more
Plus it is convenient.
The purpose of the present invention is achieved through the following technical solutions：
A kind of current collecting bow lifting device, connects the gas circuit of electrically-driven car vehicle, for the lifting of the pantograph of vehicle,
Including air spring 1, guide rod 2, guide rail cam 3 and roller 4；
Guide rail cam 3 is fixed on the underarm main shaft 6 of pantograph, and the underframe 7 of the one end of guide rod 2 and pantograph is hinged；Separately
One end is installed by roller 4；Rail contact and rolling of the roller 4 with guide rail cam 3；Air spring 1 is located between underframe 7 and guide rod 2,
The lower section of guide rod 2 is fixed in one end, and the other end is fixed on underframe 7；
Air spring 1 connects the gas circuit of electrically-driven car vehicle, and driving guide rod 2 is swung, and guide rod 2 passes through roller 4
Rotated with the driving underarm of guide rail cam 3 main shaft 6, realize the lifting of pantograph.
Described current collecting bow lifting device, in addition to mechanical position limitation mechanism, described mechanical position limitation mechanism include being fixed on
The stopper slot 8 of the upper arresting pin 5 of underframe 7 and guide rod 2；The swing angle of restricted guidance bar 2.
As seen from the above technical solution provided by the invention, current collecting bow lifting device provided in an embodiment of the present invention,
Using air spring, reliable operation, visualization are high, and regular maintenance is more convenient.Power transmission is carried out by cam structure,
Without using steel wire rope or chain, it is to avoid the generation situations such as eccentric wear of force transmission mechanism, stranded, de- groove, reliability is high.Need not
Increase joint inside air spring or linear bearing is oriented to, simple in construction, visualization is high.Air spring is vertically pacified
Dress, compared with original mounting means, will not break up during failure caused by gravity fall with roof short circuit, the wind of reduction parking operation
Danger.

Together.Those of ordinary skill in the art intelligible orientation under the premise of creative work is not made, belongs to the guarantor of the present invention
Protect scope.
The embodiment of the present invention is described in further detail below in conjunction with accompanying drawing.
Embodiment one
As shown in Figure 1, Figure 2 with shown in Fig. 3, a kind of current collecting bow lifting device, connect electrically-driven car vehicle gas circuit, be used for
The lifting of the pantograph of vehicle, including air spring 1, guide rod 2, guide rail cam 3 and roller 4；Guide rail cam 3 is fixed on by electricity
On the underarm main shaft 6 of bow, specific guide rail cam 3 is welded on underarm main shaft 6.The underframe 7 of the one end of guide rod 2 and pantograph is cut with scissors
Connect；The other end installs roller 4；Rail contact and rolling of the roller 4 with guide rail cam 3；Here it is rigid contact.Air spring
1 is located between underframe 7 and guide rod 2, and the lower section of guide rod 2 is fixed in one end, and the other end is fixed on underframe 7；Air spring 1 is connected
The gas circuit of electrically-driven car vehicle, air spring 1, which is deformed upon, to be increased, and carrying out guiding driving guide rod 2 by guide rod puts
