As an embodiment of the present invention, a support rod 10 is fixed on the outer wall of the hard extrusion plate 9, and the support rod 10 is slidably disposed in a limit groove of the inner cavity wall of the annular sliding cavity 521; during operation, when stereoplasm stripper plate 9 received the thrust lapse of last arc splint 54, the bracing piece 10 that stereoplasm stripper plate 9 lateral wall set up can carry out spacing gliding effect to stereoplasm stripper plate 9, when preventing that stereoplasm stripper plate 9 from receiving the extrusion force lapse, stereoplasm stripper plate 9 produces the phenomenon of slope or skew, and then influences the tight operation of stable clamp of last arc splint 54 and lower arc splint 53 to the rifle that charges.
The specific working process is as follows:
when the charging gun is in operation, when the charging gun needs to be placed on the operating platform 1 for maintenance, an operator firstly inserts the gun head of the charging gun into the annular sliding cavity 521 of the clamping frame 52 correspondingly, so that the lower surface of the gun head of the charging gun is attached to the upper surface of the lower arc-shaped clamping plate 53, then rotates the threaded handle 55, so that the threaded end of the threaded handle 55 moves downwards, the downward movement of the threaded handle 55 can drive the upper arc-shaped clamping plate 54 to move downwards and be attached to the upper surface of the gun head of the charging gun, and the charging gun can be clamped on the operating platform 1 through the matching of the upper arc-shaped clamping plate 54 and the lower arc-shaped clamping plate 53 along with the continuous rotation of the threaded handle 55, so that the maintenance operator can perform maintenance operation on the clamped charging gun; when a maintainer needs to adjust a gun head or a gun handle of a charging gun to be vertically upward, the maintainer pulls the pulling rings 41 on two sides of the operating platform 1, the pulling of the pulling rings 41 can slide the cross plug-in column 4 from the cross plug-in cavities 31 on two ends of the rotating support rod 3, so that the cross plug-in column 4 is separated from the rotation limit of the rotating support rod 3, then the maintainer pulls the clamping frame 52, so that the clamping frame 52 can drive the rotating support rod 3 to rotate in the storage bin 11 through the fixed base 51, the rotating support rod 3 can drive the side face of the clamping frame 52 to rotate to be parallel to the surface of the operating platform 1, then the maintainer pushes the pulling rings 41, the cross plug-in column 4 can be inserted into the cross plug-in cavities 31, and the cross plug-in column 4 can play a role in limiting rotation on the rotating support rod 3; when the clamping frame 52 rotates to a horizontal state, the clamping frame 52 can drive the head or the handle of the clamped charging gun to rotate to a vertical state; meanwhile, when the electric gun clamping device 5 on the operating platform 1 is not needed, the maintenance personnel can rotate the rotating support rod 3, so that the clamping frames 52 in a plurality of vertical states on the rotating support rod 3 can be rotated to be in a horizontal state and can be stored in the storage bin 11 of the operating platform 1, then the maintenance personnel can lay steel plates on the operating platform 1, further, other articles can be stored on the upper surface of the operating platform 1, and meanwhile, the electric gun clamping device 5 can be stored.
In the description of the present invention, it is to be understood that the terms "center", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be taken as limiting the scope of the present invention.
While the invention has been described with reference to specific embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from its scope.
