[0023] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments, and the following embodiments do not limit the invention involved in the claims. In addition, all combinations of the features described in the embodiments are not necessarily required for the solutions of the invention.
[0024] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.
[0025] Embodiment 1 like Figure 1 , 2 As shown, a cantilever scaffolding includes a cantilever beam and a positioning device for fixing a vertical pole on the cantilever beam, the cantilever beam is an I-beam 1, the positioning device includes an upper plate body 2 located above the I-beam, a lower plate body 3 located below the I-beam, and a spacing adjustment component for adjusting the spacing between the upper plate body 2 and the lower plate body 3, the upper plate body 2 is provided with a vertical pole 7 positioning sleeve 6, the vertical pole 7 can be inserted into the vertical pole 7 positioning sleeve 6 to achieve positioning relative to the upper plate body 2, and the upper plate body 2 and the lower plate body 3 are steel plates with a certain strength. In this way, the spacing between the upper plate body 2 and the lower plate body 3 is adjusted by the spacing adjustment component to control the clamping force of the upper plate body 2 and the lower plate body 3 on the I-beam 1, so that when the clamping force becomes larger, the friction force can be used to fix the position of the upper plate body 2 and the lower plate body 3 relative to the I-beam 1, that is, the position of the vertical pole 7 is fixed relative to the I-beam 1. When it is necessary to move the position of the vertical rod 7, the distance between the upper plate body 2 and the lower plate body 3 can be increased to reduce the clamping force of the two on the I-beam 1, thereby facilitating the upper plate body 2 and the lower plate body 3 to slide along the I-beam 1, thereby adjusting the position of the vertical rod 7 relative to the I-beam 1.
[0026] One end of the upper plate body 2 is connected to the lower plate body 3 through the spacing adjustment component, and the other ends of the upper plate body 2 and the lower plate body 3 are both provided with a bent portion 21 facing the edge of the I-beam 1. In this way, it is sufficient to provide a spacing adjustment component on one side of the I-beam 1, and by tightening or loosening the upper plate body 2 and the lower plate body 3 through the spacing adjustment component, the bent portion 21 will also tighten or loosen the edge of the I-beam 1 synchronously, thereby facilitating the fixing or sliding operation of the I-beam 1.
[0027] The spacing adjustment assembly includes a bolt and nut connection mechanism, and the upper plate body 2 and the lower plate body 3 are connected by the bolt and nut connection mechanism, that is, the upper plate body 2 and the lower plate body 3 are provided with holes for the bolts 4 to pass through, and the two ends or one end of the bolts 4 are matched with nuts 5. By rotating the nuts 5, the clamping force of the upper plate body 2 and the lower plate body 3 on the I-beam 1 can be adjusted.
[0028] The spacing adjustment assembly includes two parallel bolt-nut connection mechanisms, namely, two bolts 4, so as to obtain a better tensioning force, so that the positions of the upper plate body 2 and the lower plate body 3 are stable.
[0029] Embodiment 2 like Figure 3 , 4 As shown, different from the above embodiment, the spacing adjustment assembly includes a screw-thread sleeve connection mechanism, and the upper plate body 2 and the lower plate body 3 are connected by screws 8 located on both sides of the I-beam 1. It also includes a guide frame 10, and the I-beam 1 and the upper plate body 2 and the lower plate body 3 are sleeved in the guide frame 10. There are two guide frames 10, and the vertical rod 7 positioning sleeve 6 is located between the two guide frames 10.
[0030] The screw sleeve 9 of the screw sleeve connection mechanism is two, and the two screw sleeves 9 are fixed on the upper plate 2 and the lower plate 3 respectively. The screw 8 has two sections of threads in opposite directions, and the two sections of threads are respectively matched with the two screw sleeves 9 threads. When the screw 8 rotates in one direction, the two screw sleeves 9 can be relatively close to each other, and when the screw 8 rotates in the other direction, the two screw sleeves 9 can be relatively far away from each other, so that the distance between the upper plate 2 and the lower plate 3 can be controlled. The end of the screw 8 slides through the guide frame 10, and the screw 8 is provided with a stopper 11 on the upper and lower sides of the guide frame 10, so that the screw 8 can only rotate relative to the guide frame 10 but cannot move in the axial direction.
[0031] The guide frame 10 is provided with a support column 12 that slides through the upper plate 2 and the lower plate 3. One end of the support column 12 is fixedly connected to the guide frame 10 and the other end is provided with a roller 13 supported on the surface of the I-beam 1. When the distance between the upper plate 2 and the lower plate 3 increases, the upper plate 2 and the lower plate 3 can be supported by the screw 8 to leave the I-beam 1 to avoid friction during relative movement. At this time, since the guide frame 10 and the I-beam 1 are supported by the roller 13, the positioning device and the I-beam 1 are in rolling friction contact, which is conducive to relative movement of the I-beam 1. Figure 5As shown, when the distance between the upper plate body 2 and the lower plate body 3 becomes smaller, the upper plate body 2 and the lower plate body 3 are clamped on the I-beam 1. At this time, the friction between the positioning device and the I-beam 1 is the friction between the upper plate body 2 and the lower plate body 3 on the surface of the I-beam 1. The friction is relatively large, which can fix the position of the positioning device relative to the I-beam 1, thereby achieving the position fixation of the vertical rod 7. Two support columns 12 are provided corresponding to the upper plate body 2, and of course, more than two can be provided. Two support columns 12 are provided corresponding to the lower plate body 3, and of course, more than two can be provided.

Those skilled in the art may make various modifications or additions to the specific embodiments described, or replace them in similar ways, without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
