After the optimization design, the dynamic contact force adjusting function of the pantograph active control valve plate can be replaced, and compared with an active control system, the dynamic contact force adjusting system has the advantages of low cost, high reliability and the like.
Description
Technical Field

Background
The guide plate is a key part for adjusting the aerodynamic performance of the high-speed pantograph and is also the most common design means for optimizing the high-speed current collection performance of the pantograph; the quality of the current collection performance of the high-speed pantograph is directly related to the normal application of the motor train unit, so that the guarantee of the aerodynamic performance in the working height range of the pantograph is particularly important. Due to the reasons of terrain conditions, special transportation requirements (such as coastal double-layer containers) and the like, the height of a main railway contact net is changed from 5100mm to 6500mm, the pantograph can normally work at any height in the range, and higher requirements are provided for the aerodynamic regulation of the pantograph.
The existing guide plates are all arranged on the bow heads, the bow heads are basically kept horizontal within the working height range of the pantograph due to the action of the upper guide rods, and the attack angles of the guide plates arranged on the bow heads are basically kept unchanged within the whole working height range; therefore, under the condition of the same running speed, the compensation of the guide plate on the pneumatic lifting force of the pantograph is kept unchanged corresponding to different pantograph lifting heights. However, as the windward area and angle of the pantograph movable rod system are changed due to the change of the height of the pantograph, the pneumatic lifting force which needs to be compensated in different pantograph height ranges is different, so that the design compensation method of additionally arranging the guide plate on the head of the pantograph can only meet the pneumatic lifting force compensation requirement at a certain specific height, and the adjustment target in the whole working height range is difficult to ensure; meanwhile, the bow head part is more, the space is limited when the bow head part is positioned at a bow falling position, and great limitation is brought to the structural design of the guide plate; sometimes additional adjustment is required by means of active control of the valve plate.

The pantograph active control valve plate adjusting function can be completely replaced after the optimization design, and compared with an active control system, the pantograph active control valve plate adjusting system has the advantages of low cost, high reliability and the like.

In the specific embodiment, if the level of the guide plate is adjusted at the height of H2, the attack angle is 0 degree; when the height of the pantograph is changed from H2 to H3, the attack angle is changed from 0 degrees to theta 1, so that the height range of H2 to H3 is realized, and when the pantograph opening operates, the pneumatic lifting force compensation is increased along with the increase of the height of the pantograph. When the height of the pantograph is changed from H1 to H2, the attack angle is changed from theta 2 to 0 degrees, so that the height range of H1 to H2 is realized, and when the pantograph is in closed operation, the pneumatic lifting force compensation is reduced along with the increase of the height of the pantograph.
As shown in fig. 2, the baffle is installed near the upper hinge point of the lower arm rod and is completely and fixedly connected with the lower arm rod; along with the change of the height of the pantograph, the included angle between the lower arm rod and the horizontal plane is also changed continuously, so that the attack angle of the guide plate fixedly connected to the lower arm is also changed along with the change of the height of the pantograph. In the specific embodiment, if the level of the guide plate is adjusted at the height of H2, the attack angle is 0 degree; when the height of the pantograph is changed from H2 to H3, the attack angle is changed from 0 degrees to theta 1, so that the height range of the pantograph is realized from H2 to H3, and when the pantograph is in closed operation, the pneumatic lifting force compensation is increased along with the increase of the height of the pantograph. When the height of the pantograph is changed from H1 to H2, the attack angle is changed from theta 2 to 0 degrees, so that the height range of H1 to H2 is realized, and when the pantograph opening operates, the pneumatic lifting force compensation is reduced along with the increase of the height of the pantograph.
By adjusting the attack angles of the guide plate at different heights, the dynamic adjustment of the pneumatic lifting force at different heights can be realized, and the dynamic contact force compensation at different heights is met.
