Abstract
The utility model discloses a pantograph device for a locomotive. The pantograph device for the locomotive comprises a gas source part and is characterized by also comprising a front supporting bow arm and a rear supporting bow arm which are arranged sequentially, wherein a front current collecting head for taking electricity is arranged at the upper end of the front supporting bow arm; the lower end of the front supporting bow arm is connected with a front pneumatic telescopic mechanism for controlling ascending and descending of the front supporting bow arm; a rear current collecting head for taking electricity is arranged at the upper end of the rear supporting bow arm; the lower end of the rear supporting bow arm is connected with a rear pneumatic telescopic mechanism for controlling ascending and descending of the rear supporting bow arm; the gas source part is connected to the front pneumatic telescopic mechanism and the rear pneumatic telescopic mechanism respectively through gas distributing pipes by a double-way distribution valve. When a motor car or the locomotive provided with the pantograph device encounters the hard point of a cable, the electricity taking continuity can be guaranteed and parking is avoided, so that the passenger journey is not delayed, the collision accident of the motor cards caused by parking is avoided, and the driving safety of the motor car is greatly improved.
Description
Technical field
The utility model relates to the electrical equipment of a kind of electric rail car or locomotive operation, especially a kind of motorcycle pantograph device.
Background technology
Pantograph also claims collector bow, is that electric locomotive is subjected to the electrical equipment of power taking energy from contact system, is arranged on roof.Common pantograph device comprises being arranged on the arch support arm that stretching of locomotive top fallen that an arch support arm generally comprises the lower arm rod that is positioned at the below, is hinged on the lower arm rod upper end
Arch support arm top is provided with for the trolley head from the overhead cable power taking, and arch support arm lower end is connected with Pneumatic extension mechanism, and Pneumatic extension mechanism partly is connected with source of the gas by tracheae.Described Pneumatic extension mechanism generally comprises a cylinder, has piston in cylinder, and piston two ends are provided with and fall bow spring and rising bow spring, also has pantograph valve with the tracheae junction on cylinder.When it used rising bow, pressurized air evenly entered the transmission cylinder through pantograph valve, fell the bow spring in the cylinder piston compression cylinder, this moment, the rising bow spring made the lower arm rod rotation of propping up arch support arm lower end, lift upper frame and trolley head, pantograph evenly rises, and is subjected to electricity with the contact system contact.When it fell bow, transmission cylinder compressed air, was falling under the bow action of the spring rapidly discharged to atmosphere through the pantograph cushion valve, overcomes the application force of rising bow spring, and pantograph is descended rapidly, disengages net.
Existing this pantograph device, in use, due to overhead cable netting twine long term exposure in air; usually can produce in contact system with the pantograph contact force and change suddenly the place of causing hook to break off relations; be called hard spot, when pantograph runs into hard spot, due to the variation of contact force; can cause scraping the bow phenomenon; make locomotive or motor-car automatic bow-lowering, cause locomotive or motor-car to stop, so not only stopped over stroke; and easily accidents caused because of temporary term stop, cause the heavy losses of life and property.
The utility model content
For the deficiencies in the prior art, technical problem to be solved in the utility model is, how to provide a kind of when running into the cable hard spot, can avoid the motorcycle pantograph device that stops, can guarantee the motor-car driving safety.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
A kind of motorcycle pantograph device, comprise the source of the gas part, it is characterized in that, the front support bow arm that before and after also comprising, order arranges and rear support bow arm, front support bow arm upper end has the front trolley head for power taking, and front support bow arm lower end is connected with for the front Pneumatic extension mechanism that controls the lifting of front support bow arm; Described rear support bow arm upper end has the rear trolley head for power taking, and rear support bow arm lower end is connected with for the rear Pneumatic extension mechanism that controls the lifting of rear support bow arm; Two-way distributing valve by a setting on described source of the gas part freeing pipe is connected to front Pneumatic extension mechanism and rear Pneumatic extension mechanism by gas-distributing pipe respectively.Wherein said two-way distributing valve, the air-flow triple valve that refers to have electronic control function, air-flow triple valve have an inlet end and two outlet sides, can electronic control the conversion of outlet side, self belong to existing matured product.
When the utility model uses, in two cover pantographs, be positioned at the pantograph normal operation in the place ahead, and the rear is standby.Front support bow arm upwards rises, and front trolley head contacts with cable and carries out power taking.The control part of described two-way distributing valve is connected to control center, when control center detects that front trolley head runs into the hard spot on cable and when causing front support bow arm to scrape bow being fallen, control center controls two-way distributing valve action, switch the current direction of air-flow, make the air pressure of source of the gas part can arrive the rear Pneumatic extension mechanism of rear support bow arm lower end, and then drive the rise of rear support bow arm, and make rear trolley head and cable contact electricity getting, guarantee the continuity of power taking.And then avoid because of run into the cable hard spot scrape the bow stop.
In sum, motor-car of the present utility model or locomotive are installed, when running into the cable hard spot, can guarantee the continuity of power taking, avoid stopping, and then guaranteed that passenger's stroke can not delay, avoid simultaneously greatly having improved because parking causes motor-car collision accident the safety that motor-car travels.
Description of drawings
Structural representation sketch when Fig. 1 is the utility model enforcement.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of motorcycle pantograph device, comprise source of the gas part 1, the front support bow arm 2 that before and after it also comprises, order arranges and rear support bow arm 3, front support bow arm 2 upper ends have the front trolley head 4 for power taking, and front support bow arm 2 lower ends are connected with for the front Pneumatic extension mechanism 5 that controls 2 liftings of front support bow arm; Described rear support bow arm 3 upper ends have the rear trolley head 6 for power taking, and rear support bow arm 3 lower ends are connected with for the rear Pneumatic extension mechanism 7 that controls 3 liftings of rear support bow arm; Two-way distributing valve 8 by a setting on described source of the gas part 1 freeing pipe is connected to front Pneumatic extension mechanism and rear Pneumatic extension mechanism by gas-distributing pipe respectively.
During concrete enforcement, described two-way distributing valve self structure is existing product, not at this detailed description.
When the utility model is installed and used, the control part of described two-way distributing valve need to be connected to control center, when control center detects that front trolley head runs into the hard spot on cable and when causing front support bow arm to be fallen, control center controls two-way distributing valve action, switch the current direction of air-flow, make the air pressure of source of the gas part can arrive the rear Pneumatic extension mechanism of rear support bow arm lower end, and then drive rear support bow arm and rise, make rear trolley head and cable contact electricity getting, guarantee the continuity of power taking.And then avoid stopping because running into the cable hard spot.
