Description
Technical Field
The invention belongs to the field of railway vehicles, and relates to a guide cover and bow head assembly of a single-carbon slide plate pantograph.
Background
The pantograph is an electrical device for an electric traction locomotive to obtain electric energy from a contact net, and the electric energy is obtained through the contact of a carbon sliding plate of the pantograph and the contact net to provide power for vehicles. Therefore, the stability of the contact pressure between the pantograph and the contact net is a precondition for ensuring the reliable current receiving of the pantograph. When the train runs, the structure of the pantograph is restricted, the lifting force of the passive pantograph in the closed running direction is usually larger than the lifting force in the opening running direction, and correspondingly, the contact force of the bow net in the closed running direction is larger than the contact force of the bow net in the opening running direction, so that the difference value of the contact forces of the bow net in the opening and closing running directions can influence the current receiving performance of the pantograph. Therefore, in the passive pantograph, a baffle plate forming a look-up angle with the opening running direction is added to both sides of the pantograph head assembly, and a baffle plate forming a look-up angle with the closing running direction is generally arc-shaped and is fixed on the insulating pantograph corner and the carbon slide plate bracket through brackets. The deflector which forms a upward viewing angle when the pantograph opening operates can effectively intercept air resistance, and ascending aerodynamic force is obtained; the deflector which forms a overlook angle during closed operation can obtain downward aerodynamic force, thereby adjusting the dynamic contact pressure of the pantograph net in the opening and closing direction of the pantograph during high-speed operation and improving the current receiving quality of the open and closed operation of the pantograph.
The current pantograph used for the railway vehicle is mainly divided into: a single carbon slide plate pantograph, a double carbon slide plate pantograph, a four carbon slide plate pantograph, and the like. When the vehicle runs at a high speed, the pantograph of the multi-carbon slide plates such as the double-carbon slide plate and the four-carbon slide plate has larger air disturbance among the carbon slide plates due to larger volume and larger mass of the bow heads, so that the current-receiving stability is poor. Therefore, for high-speed vehicles, a single carbon slide plate pantograph is generally employed. The bow head assembly of the single-carbon slide pantograph cannot form a frame structure between the carbon slide plates like the bow head assembly of the multi-carbon slide pantograph, so that the structure of the bow head assembly of the single-carbon slide pantograph is relatively thin, if the guide plates are arranged on two sides of the bow head assembly of the single-carbon slide pantograph, when a vehicle runs at a high speed, the large resistance formed by air to the guide plates easily causes bending deformation of the bow head assembly to influence the contact response speed of the carbon slide plate and a contact net, and poor contact is caused.
However, the existing guide plate needs to be fixed through a bracket, and for a bow head assembly of a single-carbon sliding plate pantograph, on one hand, the bow head area is narrow in space, and the bracket is inconvenient to install; on the other hand, the bracket has certain weight and volume, so that the weight and wind resistance of the bow head can be increased, and the load on the bow head is increased.
Disclosure of Invention
In order to reduce the weight and the volume of the guide plate as much as possible, and enable the guide plate to be suitable for a single-carbon slide plate pantograph, the invention aims to provide a guide cover of the single-carbon slide plate pantograph, and the guide cover not only can stabilize the contact force of a pantograph net, but also can be directly arranged on a rotating shaft of a pantograph head assembly, and is not required to be fixed by a bracket, so that the volume and the weight required by the bracket are reduced, the weight and the wind resistance of a pantograph head are reduced, and the burden of the pantograph head is lightened.
In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:
the utility model provides a kuppe of single carbon slide pantograph, includes the cover body, the top surface of the cover body is the plane, and one side of top surface has by the top to the inboard inclined plane of the cover body, and the opposite side of top surface has by the protruding kink surface in top to the outside of the cover body, and the side terminal surface of the cover body is equipped with the fixed orifices. The fixing holes can be directly sleeved on the rotating shaft of the pantograph of the single-carbon slide plate to fix, so that a bracket is not needed. The top surface of the air guide sleeve is a plane, and one side of the inclined surface of the air guide sleeve faces the running direction of the opening of the vehicle, so that when the vehicle runs towards the opening direction, the air flow generates upward lifting force on the air guide sleeve. One side of the air guide sleeve bending surface faces the vehicle closing running direction, so that when the vehicle runs towards the closing direction, air flow simultaneously generates upward lifting force and downward pressure on the air guide sleeve, the lifting force received by the air guide sleeve bending surface can be smaller than the lifting force received by the air guide sleeve inclined surface, and the lifting force received by the corresponding pantograph when running in the closing direction is smaller than the lifting force received by the pantograph in the opening direction, so that the difference value of the contact force of the pantograph net in the opening and closing running directions of the pantograph is reduced.
Preferably, the cover body is formed by splicing a left cover shell and a right cover shell. The cover body is divided into two parts and is isomorphic, so that the installation and the disassembly of the guide cover can be facilitated.
Preferably, the left cover shell comprises a left folded plate bent in a 7 shape and left sealing plates which are arranged at two ends of the inner side of the left folded plate and are perpendicular to the left folded plate; the right cover shell comprises a right folded plate bent in a C shape and right sealing plates which are arranged at two ends of the inner side of the right folded plate and perpendicular to the right folded plate, the top surface of the cover body is formed by splicing upper folded surfaces of the left folded plate and the right folded plate, and the side end surfaces of the cover body are formed by splicing the left sealing plate and the right sealing plate. The left and right covers are formed by splicing plates, and a main body structure left folded plate of the left cover can be obtained by only bending the plates in a 7 shape once; similarly, the main structure right folded plate of the right housing can be obtained by bending the two sides of the plate in the shape of the C towards the same side, and the processing difficulty is low, and the structure is light and simple.
Based on the same technical conception, the invention also provides a bow head assembly of the single carbon slide plate pantograph, which comprises a bow head suspension, bow corners arranged at two sides of the bow head suspension, a carbon slide plate arranged at the top of the bow head suspension and a rotating shaft arranged in the middle of the bow head suspension, wherein a guide cover of the single carbon slide plate pantograph is arranged in the middle of the rotating shaft. The guide cover is arranged on the rotating shaft in the middle of the bow head suspension, so that bending deformation of the bow head assembly caused when the guide plate is arranged on two sides of the bow head assembly is avoided, the contact response speed between the carbon slide plate and the contact net can be ensured, and the contact stability between the carbon slide plate and the contact net is ensured.
The invention has the beneficial effects that: the guide cover of the single-carbon slide plate pantograph can not only stabilize the contact force of the pantograph net, but also be directly arranged on the rotating shaft of the pantograph head assembly without fixing by using a bracket, thereby reducing the volume and weight required by the bracket, reducing the weight and wind resistance of the pantograph head and lightening the burden of the pantograph head. The guide cover is installed in the middle of the rotating shaft of the bow head assembly of the single-carbon slide plate pantograph to replace guide plates installed on two sides of the bow head assembly, so that bending deformation of the bow head assembly caused by high-speed operation of a vehicle can be avoided, the contact response speed between the carbon slide plate and a contact net can be ensured, and the contact stability between the carbon slide plate and the contact net is ensured.
