A cable tray bolt punching apparatus as defined in claim 6, wherein, The drilling assembly (67) comprises: A bidirectional screw rod (671) is rotatably connected to the inner wall of the adjusting groove of the moving frame (64); A sliding block (672) is threadedly connected to the bidirectional screw rod (671); A fixed plate (673) is fixedly connected to the sliding block (672); A bearing plate (674) is slidingly sleeved on the outside of the fixed plate (673), and the bearing plate (674) cooperates with the push frame (663); An electric drill bit (675) is fixedly installed at the top end of the bearing plate (674); A positioning pin (676) is threadedly connected to the inner cavity of the positioning hole of the fixed plate (673).

8. A method of using a cable tray bolt punching apparatus as defined in claim 7, wherein, The following specific use steps are included: Step one: the cross plate (1) is placed on the top of the cable trench, and the position of the bearing plate (674) is adjusted through the positioning pin (676), so that the bearing plate (674) adjusts the position of the push frame (663), and the matching wheel (665) on the matching frame (664) can adapt to the current width of the cable trench, that is, the cross plate (1) can be moved by moving the roller (3), the position of the vertical plate (2) in the cable trench is adjusted, and it is stopped when it reaches the punching position, and the sliding block (672) drives the fixed plate (673) to displace in the vertical direction by rotating the double screw rod (671), so as to determine the distance between the electric drill (675) in advance; Step two: start the electric push rod (51), the electric push rod (51) is displaced for the first time, the inclined slot of the push plate (54) extrudes the roller (44), so that the limiting plate (42) is lowered to extrude and position the moving roller (3), and at the same time, the rack plate (56) is displaced by the push plate (54), so that the drill mechanism (6) is pushed by the push rod (57), so that the electric drill (675) is close to the inner wall of the cable trench, so as to be pre-positioned and determine the punching position; Step three: when the punching position is determined, start the electric drill (675), and displace the electric push rod (51) for the second time to realize the punching operation, and after the punching is completed, the electric push rod (51) is reset, so that the electric drill (675) is separated from the side wall of the cable trench and stops rotating, and at the same time, the limiting plate (42) is away from the moving roller (3), so that the whole device can continue to move to the next position for punching operation.
