Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Referring to fig. 1-4, a novel rotary drilling machine diagonal brace comprises a drill frame 1, an oil cylinder 2 is arranged in one side of the drill frame 1, a support frame 3 is movably connected to the telescopic end of the oil cylinder 2, a mounting frame 4 is welded at the top of one side of the drill frame 1, a clamping shaft 5 is movably connected to the mounting frame 4 through a bearing, a connecting pipe 6 is sleeved on the surface of the clamping shaft 5, a telescopic rod 7 is clamped on the inner side of the bottom of the connecting pipe 6, a push rod 8 is welded on the outer side of the telescopic rod 7, a spring 9 is sleeved on the push rod 8, a handle 10 is sleeved at one end of the push rod 8, a fixing plate 13 is movably connected to the outer side of the bottom of the telescopic rod 7, a sliding shaft 11 is clamped on the outer side of the telescopic rod 7, and a limiting rod 12 is sleeved on the surface of the sliding shaft 11.

The surface of the telescopic rod 7 is vertically provided with a chute matched with the sliding shaft 11. One end of the spring 9 is contacted with the inner side of the connecting pipe 6, the other end is contacted with the back of the telescopic rod 7, a latch is arranged on one side of the telescopic rod 7, a clamping groove matched with the latch is formed in the inner side of the connecting pipe 6, a kidney-shaped hole matched with the push rod 8 is formed in the outer side of the connecting pipe 6, and a jack is formed in the surface of the fixing plate 13.

In this embodiment, when the drill frame 1 needs to be effectively supported by using the diagonal brace, the oil cylinder 2 extends to push the support frame 3 forward, and one side of the support frame 3 is in an opening form and is clamped outside the connecting pipe 6, so that the connecting pipe 6 can be lifted in the forward pushing process of the support frame 3 and effectively attached to the connecting pipe 6, and the connecting pipe 6 is supported in the punching process.
