[0020] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:
[0021] like Figures 1 to 4The device for stabilizing the butt joint of a large-diameter pipe orifice is shown, comprising an inner ring 1 arranged inside the pipe, a plurality of retractable extension brackets 2 arranged on the periphery of the inner ring 1, a butt joint component 3 that can be butt jointed with another pipe orifice, a driving device 4 that can drive the butt joint component 3 to be retracted and movable, and a magnetic device 5 that can simultaneously lock the butt joint component 3 and is tightly connected to the pipe orifice. The device of this technical solution can be fixed in a metal pipe by means of a plurality of extension brackets on the inner ring in cooperation with the driving device and the magnetic device, and the butt joint component can be started to be extended while the driving device is driven, and when a plurality of butt joint components are extended, another pipe can be sleeved on the plurality of butt joint components to achieve guided butt joint, which has the functions of preventing the pipe from being displaced and moved, preventing misalignment and alignment, and stabilizing the pipe.
[0022] The extension bracket 2 in the utility model includes a plurality of slide grooves 21 evenly distributed and installed on the periphery of the inner ring 1, and an outer support frame 22 that can limit and linearly slide in the slide groove 21 is arranged, and a support seat 23 is arranged at the outer end of the outer support frame 22. The slide groove is fixedly connected to the inner ring and is arranged on the inner ring in a circular array. The movement direction of the outer support frame is linear sliding from the inside to the outside or from the outside to the inside, so that the extension length of the extension bracket can be increased, and the pipes of more sizes can be adapted, and the support seat can be more closely attached to the inner wall of the pipe. The support seat and the outer support frame are fixedly connected.
[0023] The outer support frame 22 and the slide slot 21 in the utility model are hinged by a rotating shaft so as to be rotatably connected. When the magnetic attraction device is not started, the outer support frame is in a state of being able to swing freely, so the device can be conveniently folded and taken away, and opened for use when in use.
[0024] The docking component 3 in the utility model includes a T-shaped groove 31 arranged on the side of the support seat 23 close to the inner wall of the pipe, and a T-shaped slider 32 that can move linearly forward and backward is arranged in the T-shaped groove 31, and the front upper wall and the rear lower wall of the T-shaped slider 32 are both provided with inclined surfaces 33. The T-shaped groove is located on the side close to the inner wall of the pipe, and the T-shaped slider is arranged on the inner and rear outer wall of the T-shaped slider to be close to the inner wall of the pipe, in order to restore the inner diameter size of the original pipe. The relationship between the T-shaped slider and the T-shaped groove is that the T-shaped slider can slide linearly in the T-shaped groove, and the protruding distance of the T-shaped slider is limited, which can be specifically achieved by setting a limit block and a limit groove.

When the electric push rod is started, it presses the inclined surface of the lower wall of the rear end of the T-shaped slider to make it protrude forward, and when the movable end of the electric push rod pushes the T-shaped slider to the limit position, it can prevent the T-shaped slider from returning to its original position.
