Description

Technical Field

[0001] The utility model relates to the technical field of electric locomotives, in particular to a pantograph valve plate component installation structure. Background Art

[0002] The pantograph valve plate is mainly used to control the pantograph raising and lowering of the road vehicle. The valve plate is usually equipped with a filter for filtering the air entering the valve plate, a pressure regulating valve for adjusting the pantograph raising force, a throttle valve for adjusting the pantograph raising and lowering time, a safety valve and a quick release valve for releasing wind pressure, and a pressure switch for feedback signals. The installation of components on the existing pantograph valve plate is mostly carried out by welding, bolts or other fixing methods. However, these installation methods often have the following shortcomings:

[0003] 1. In order to meet the installation requirements of components, the existing pantograph valve plate often needs to be designed and planned in detail during the production and processing of the pantograph valve plate, including determining the type, size, position and layout relationship of each component. This results in that the pantograph valve plate can only be planned and installed for a single component. If the layout or model of the components changes during subsequent use, it will directly have an adverse effect on the installation and connection of the components. In serious cases, the pantograph valve plate needs to be re-prepared;

[0004] 2. When drilling holes for installing components on the existing pantograph valve plate, corresponding holes need to be drilled on the pantograph valve plate according to the size of the components, which means that the installation position can only be used for components of this model. This means that if there is a deviation in the drilling, the components cannot be installed and it is necessary to drill holes again. In serious cases, a new pantograph valve plate needs to be replaced, which also affects the subsequent update and installation of new components.

[0005] 3. If the components are directly welded to the pantograph valve plate, the connection between the components and the pantograph valve plate cannot be disassembled. If the components fail, disassembly and replacement are very cumbersome and inconvenient;

[0006] Therefore, there is an urgent need for a pantograph valve plate device installation structure that can overcome the above-mentioned shortcomings. Utility Model Content

[0007] In order to overcome the shortcomings of the background technology, the utility model discloses a pantograph valve plate component installation structure. The utility model avoids the traditional method of directly welding or punching components on the valve plate, and utilizes a mounting plate that can be slidably adjusted and disassembled and installed, which ensures strong support for the precise and efficient corresponding connection of components, and provides great convenience for the subsequent disassembly and replacement of components.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

Both sides of the lower surface of the fixing plate are provided with sunken screw holes which correspond to and fit the fixing screw holes on both sides of the slide groove. Fixing screws are provided in the corresponding sunken screw holes and the fixing screw holes.

[0012] Furthermore, a through hole corresponding to the insertion rod and penetrating the fixed plate is provided on the upper surface of the fixed plate, a rotating block is rotatably installed in the through hole, and a mounting screw hole threadedly connected to the insertion rod is provided on the side of the rotating block facing the insertion rod.

[0016] By setting up the mounting plate, components can be directly punched or welded on the mounting plate, avoiding the traditional method of directly punching or welding on the valve plate, providing strong support for the subsequent secondary use of the valve plate;

[0017] By setting a detachable fixing plate, the installation plate can be disassembled and replaced, providing strong support for the subsequent replacement and installation of components;

[0018] Fixing the fixing plate with fixing screws can effectively ensure the firmness and stability of the mounting plate, providing strong guarantee for the subsequent use of the valve plate;

The rotating block 16 is provided with a mounting screw hole 14 threadedly connected to the plug rod 10 on the side facing the plug rod 10. The plug rod 10 and the fixed plate 11 are detachably connected through the threaded connection between the plug rod 10 and the mounting screw hole 14 on the rotating block 16. In order to facilitate the rotation of the rotating block 16, a groove 17 is provided on the side of the rotating block 16 facing away from the plug rod 10, and a rotating handle 18 is provided in the groove 17. When the fixed plate 11 is connected and fixed to the plug rod 10, the fixed plate 11 and the mounting plate 8 are respectively attached to the lower and upper surfaces of the valve plate 3, and each vertex of the upper surface of the valve plate 3 is provided with a mounting hole 1;

[0030] When installing components, the staff first installs each component on the corresponding mounting plate 8. During installation, holes can be punched or welded directly on the mounting plate 8, avoiding the traditional method of directly installing on the valve plate 3. Then, the mounting plate 8 is adjusted and pushed along the slide groove 2 according to the size specifications of each component, so that the direct connection ports of adjacent components correspond to each other. After the adjustment is completed, the fixing plate 11 is installed to fix the mounting plate 8, and then the various components can be connected. If it is necessary to re-drill or weld new components later, it is only necessary to remove the corresponding mounting plate 8 and replace it with a new mounting plate 8 for installation.

[0031] Embodiment 2, in order to facilitate the subsequent horizontal and stable installation of the valve plate 3, a lower limit groove 6 for expanding the diameter of both sides of the groove of the slide groove 2 is provided at the groove opening of the slide groove 2 located on the lower surface of the valve plate 3, the width of the fixed plate 11 is adapted to the groove width of the lower limit groove 6, the thickness of the fixed plate 11 is adapted to the groove depth of the lower limit groove 6, when the fixed plate 11 is threadedly connected and fixed with the insert rod 10, the fixed plate 11 is just inserted into the lower limit groove 6, so that the lower surface of the valve plate 3 is horizontal.

[0032] Embodiment three, in order to ensure that the adjusted mounting plate 8 remains in a fixed position and provide strong support for the subsequent connection and use of components, the bottom surface of the lower limit groove 6 is provided with a plurality of fixing screw holes 7 which are arranged in an orderly manner along the axial direction of the slide groove 2 and are evenly distributed on both sides of the notch of the slide groove 2, and both sides of the lower surface of the fixing plate 11 are provided with sunken screw holes 13 corresponding to and adapted to the fixing screw holes 7 on both sides of the slide groove 2, and fixing screws 15 are provided in the corresponding sunken screw holes 13 and the fixing screw holes 7, and the fixing plate 11 is limited and fixed by the fixing screws 15, thereby effectively preventing the mounting plate 8 from sliding.

[0033] In the fourth embodiment, since the plug rod 10 and the rotating block 16 connected with the thread can rotate, during the working process of each component on the valve plate 3, the vibration of the components will be transmitted to the mounting plate 8. Since the fixing screws 15 can only fix the fixing plate 11 to prevent the mounting plate 8 from sliding, it cannot guarantee that the mounting plate 8 will not deflect due to vibration. If the mounting plate 8 rotates with a large amplitude, it is very easy to cause the mounting plate 8 to loosen. In order to prevent the mounting plate 8 from rotating, an upper limit groove 5 for expanding the diameter of both sides of the groove of the slide groove 2 is provided at the notch of the slide groove 2 on the upper surface of the valve plate 3, and a limit plate 9 is provided on the lower surface of the mounting plate 8 with a groove width and groove depth adapted to the upper limit groove 5. The plug rod 10 is fixedly connected to the lower surface of the limit plate 9. The clamping connection between the limit plate 9 and the upper limit groove 5 can effectively prevent the mounting plate 8 from rotating.
