as shown in fig. 1 and 2, the guide section 2 comprises a horn section 21 and a cylindrical section 22 which are coaxially communicated; the horn section 21 is located above the cylindrical section 22; the inner diameter of the cylindrical section 22 is the same as or slightly larger than the outer diameter of the flange at the bottom end of the upper steel pipe pole so as to be convenient for adapting to flanges with different sizes. In this embodiment, the horn section 21 is used as a guide, so that the upper steel pipe pole can be guided to be positioned roughly, and when the upper steel pipe pole gradually enters the cylindrical section 22 from the horn section 21, the accurate positioning is completed. Because the upper steel pipe rod and the lower steel pipe rod are not fixed at this time and are in a suspension state, the cylindrical section 22 has a certain height in the embodiment, so that the perpendicularity of the upper steel pipe rod can be limited, and the butting precision of the flanges of the upper steel pipe rod and the lower steel pipe rod is ensured. In addition, in order to reduce friction and noise when the upper steel pipe rod moves downwards from the horn section 21, the present embodiment further installs a plurality of rollers 211 on the wall of the horn section 21, and as shown in fig. 3, friction and noise reduction are realized by rolling engagement with the balls when the upper steel pipe rod falls.

In this embodiment, the swing arm 33 may be made of i-steel or C-steel, and the first driving member 31 and the second driving member 32 are driving motors to drive the swing arm 33 and the first friction wheel 34 to rotate respectively. The friction wheel is made of materials such as silica gel with a large friction coefficient, and slipping with the outer wall of the steel pipe rod is avoided.
In order to adapt to steel pipe rods with different diameters, the swing arm 33 comprises a first swing arm section 331 and a second swing arm section 332; the side of the swing arm first section 331 facing the window 221 is elastically connected with the swing arm second section 332 through a spring 333, and the side of the swing arm second section facing away from the window 221 is connected with the swing arm second section through an elastic block 334.

The elastic block 334 is made of flexible materials such as rubber and silica gel, is approximately square, covers the outer walls of the wing plates of the first swing arm section 331 and the second swing arm section 332, and is fixed with the first swing arm section 331 and the second swing arm section 332 respectively through bolts. In this embodiment, the spring 333 has a certain stiffness, when the first swing arm section 331 and the second swing arm section 332 are in a straight line, the spring 333 is in a natural state, the elastic block 334 is not bent, when the first driving member 31 is started, the swing arm 33 moves towards the window 221, the first friction wheel 34 abuts against the outer wall of the upper steel pipe rod, under the action of the abutting force, the first swing arm section 331 and the second swing arm section 332 form an included angle, the spring 333 is pressed, and under the reaction of the spring 333, the rotation angle of the first swing arm section 331 is limited, so that the first friction wheel 34 can be tightly abutted against the upper steel pipe column, and meanwhile, due to the certain flexibility of the spring 333, a certain buffer margin can be provided for the first friction wheel 34 and the upper steel pipe column. Of course, the elastic block 334 also plays the same role as the spring 333, under the action of the spring 333 and the elastic block 334, the first friction wheel 34 is always tightly abutted against the outer wall of the upper steel pipe rod, at this time, the second driving piece 32 is started, and under the rotation driving of the first friction wheel 34, the upper steel pipe rod is enabled to rotate circumferentially until the screw holes of the upper steel pipe rod and the lower steel pipe rod are centered.
In this embodiment, since the operation is unmanned, the monitor unit 6 needs to be provided to monitor whether the upper and lower screw holes are aligned. In this embodiment, as shown in fig. 5, the monitoring unit 6 is a camera fixed on a section 331 of the swing arm through a bracket, the camera extends horizontally towards the window 221, and enters the cylindrical section 22 from the window 221 along with the rotation of the swing arm 33, when the first friction wheel 34 rotates the upper steel pipe rod, the camera shoots the lower flange of the upper steel pipe rod from top to bottom, and sends the shot picture or video to the ground, the first driving member 31 and the second driving member 32 are manually controlled to stop acting, or the automatic control is used for acquiring images and identifying targets, and when the upper screw hole and the lower screw hole are aligned, the first driving member 31 and the second driving member 32 are controlled to stop acting through a control program.
In this embodiment, in order to reduce the overall height of the device, the first driving member 31 is fixed with the mounting bracket 35 in a transverse direction, and the output shaft of the first driving member 31 passes through the fixing bracket to be linked with a worm gear (not shown in the figure), so that the horizontal rotating shaft is converted into the vertical rotating shaft 311 through the worm gear, and the vertical rotating shaft 311 is fixed with the second swing arm section 332 through the rotating shaft flange, thereby not only driving the swing arm 33 to rotate, but also reducing the overall height of the device.
