[0018] 1. A telescopic splicing adjustment mechanism is installed. The support frame is formed by splicing horizontal bars, splicing diagonal bars, and supporting columns. By twisting the threaded support rods, the bottom end is made to fit tightly with the ground to provide auxiliary support to the bottom of the supporting columns. When it is necessary to expand the support area at the bottom of the scaffolding uprights, the length of the horizontal bars (splitting the horizontal bars) and diagonal bars (splitting the diagonal bars) can be adjusted by loosening the splicing hoops. The two ends of the diagonal bars can swing along the ends of the connecting uprights and supporting columns through the splicing bolts. After the splicing horizontal bars and diagonal bars are adjusted to the appropriate position, they are fixed by the splicing hoops, thereby strengthening the bottom of the mobile scaffolding. By actively increasing the bottom support area of the scaffolding, the scaffolding remains stable even when it is raised, effectively improving the stability and safety of the scaffolding.

The tilt angle of the connecting block is adjusted by the splicing arc seat, so that the infrared distance sensor can be installed horizontally at the end of the splicing diagonal rod. When the scaffolding shakes, it will cause the splicing diagonal rod to swing, which will cause the infrared distance sensor to tilt and swing. When the infrared distance sensor swings, it will detect the change in the distance between the bottom surface and the ground. The flashing of the alarm indicator light will remind the scaffolding that it has slipped, so that the staff can find the problem of the scaffolding in time and eliminate it, which will further improve the safety of the scaffolding.
[0020] 3. An elastic auxiliary limiting mechanism is set up, which limits the sides of the splicing horizontal bars and splicing diagonal bars by connecting inclined plates, flexibly binds the splicing horizontal bars and splicing diagonal bars by connecting elastic bands, and reinforces the sides of the connecting inclined plates by supporting strips, so as to prevent misalignment between the splicing horizontal bars and splicing diagonal bars, thereby effectively improving the stability of each component during the scaffolding adjustment process.

[0032] Example: Figure 1-4 As shown, this utility model provides a technical solution: a retractable mobile scaffolding anti-tipping early warning device, including a scaffolding upright 1, and a telescopic splicing adjustment mechanism 2 is provided on one side of the scaffolding upright 1;
[0033] The telescopic splicing adjustment mechanism 2 includes a connecting upright 201, a splicing horizontal bar 202, a splicing diagonal bar 203, a splicing hoop 204, a supporting column 205, a threaded support rod 206, and a splicing bolt 207;

A splicing horizontal bar 202, 50cm long, is installed at the bottom of one side of the connecting upright 201. A splicing diagonal bar 203, 80cm long, is installed at the top of one side of the connecting upright 201. Splicing hoops 204 are tightly adjusted on the outer sides of the connecting upright 201, the splicing horizontal bar 202, and the splicing diagonal bar 203. The splicing horizontal bar 202 at the end is fixedly connected to a supporting column 2. 05. The length of the support column 205 is 60cm. A threaded support rod 206 is installed in the middle of the bottom surface of the support column 205 via threads. The top of the connecting column 201 and the support column 205 are both connected by splicing bolts 207. Each set of splicing horizontal bars 202 and splicing diagonal bars 203 is provided with three bars. The connecting column 201, splicing horizontal bars 202, splicing diagonal bars 203 and support column 205 are all 42mm galvanized steel. The splicing horizontal bars 202 are spliced together by splicing clamps 204, and the splicing diagonal bars 203 are connected by... The scaffolding is spliced together using splicing collars 204. The connecting uprights 201 and support columns 205 are then spliced with the corresponding splicing horizontal bars 202 using splicing bolts 207. The splicing horizontal bars 202, splicing diagonal bars 203, and support columns 205 together form a support frame. Twisting the threaded support rods 206 ensures a tight fit between its bottom end and the ground, providing auxiliary support to the bottom of the support columns 205. When it is necessary to increase the support area at the bottom of the scaffolding uprights 1, the splicing collars 204 can be loosened to allow for splicing of the horizontal bars 202.

After the splicing horizontal bar 202 and the splicing diagonal bar 203 are adjusted to the appropriate position, they are fixed by the splicing hoop 204, thereby realizing the reinforcement of the bottom of the mobile scaffold. By actively increasing the bottom support area of the scaffold, the scaffold can remain stable even after it is raised, effectively improving the stability and safety of the scaffold.
[0035] An end balance detection mechanism 3 is provided at the end of the splicing diagonal bar 203;
[0036] The end balance detection mechanism 3 includes a splicing rubber plug 301, a connecting disc 302, a splicing arc seat 303, a connecting block 304, an infrared distance sensor 305, and an alarm indicator light 306;
[0037] A splicing plug 301 is tightly engaged at the end of the splicing diagonal rod 203. A connecting disc 302 is adhered to the end of the splicing plug 301. A splicing arc-shaped seat 303 is fixedly connected to the middle of one side of the connecting disc 302. A connecting block 304 is rotatably mounted on the end of the splicing arc-shaped seat 303 via a connecting bolt. An infrared distance sensor 305 is fixedly mounted on the middle of the bottom surface of the connecting block 304. An alarm indicator light 306 is fixedly connected to the middle of the top surface of the connecting block 304. The outer side of the splicing plug 301 and the inner wall of the splicing diagonal rod 203 are tightly slidably fitted together. The signal output terminal of the infrared distance sensor 305 is interconnected with the signal input terminal of the alarm indicator light 306. The splicing plug 301 transmits signals to the infrared distance sensor 305. The connecting disc 302 and its components are snapped onto the end of the splicing diagonal bar 203. The tilt angle of the connecting block 304 is adjusted by the splicing arc seat 303, so that the infrared distance sensor 305 can be horizontally installed at the end of the splicing diagonal bar 203. When the scaffolding shakes, it will cause the splicing diagonal bar 203 to swing, which will cause the infrared distance sensor 305 to tilt and swing. When the infrared distance sensor 305 swings, it will detect the change in the distance between the bottom surface and the ground. The flashing of the alarm indicator light 306 will remind the scaffolding that it has slipped, so that the staff can find the problem of the scaffolding in time and eliminate it, further improving the safety of the scaffolding.
[0038] Both the splicing crossbar 202 and the splicing diagonal bar 203 are covered with an elastic auxiliary limiting mechanism 4 on their outer sides;
[0039] The elastic auxiliary limiting mechanism 4 includes a connecting inclined plate 401, a supporting strip 402, and a connecting elastic band 403;
[0040] Both the horizontal and diagonal braces 202 and 203 are symmetrically equipped with connecting inclined plates 401. Support strips 402 are evenly and equidistantly bonded to the sides of the connecting inclined plates 401. Connecting elastic bands 403 are fixedly connected to both ends of the connecting inclined plates 401. The sides of the connecting inclined plates 401 are tightly fitted to the horizontal and diagonal braces 202 and 203, and the outer side of the connecting elastic bands 403 is also tightly fitted to the horizontal and diagonal braces 202 and 203. The connecting inclined plates 401 limit the movement of the sides of the horizontal and diagonal braces 202 and 203, the connecting elastic bands 403 flexibly bind the horizontal and diagonal braces 202 and 203, and the support strips 402 reinforce the sides of the connecting inclined plates 401 to prevent misalignment between the various sets of horizontal and diagonal braces 202 and 203, thereby effectively improving the stability of each component during scaffolding adjustment.
[0041] The working principle and usage process of this utility model are as follows: In practical application, when processing the bottom of the scaffolding, the connecting uprights 201 are first bound to the side of the scaffolding uprights 1 using splicing hoops 204. Then, the components on the side of the connecting uprights 201 are installed onto the side of the scaffolding. The splicing horizontal bars 202, splicing diagonal bars 203, and supporting columns 205 are then spliced together to form a support frame. Finally, the threaded support rods 206 are twisted to ensure their bottom ends are tightly fitted to the ground, providing auxiliary support to the bottom of the supporting columns 205. This process is repeated when the support area at the bottom of the scaffolding uprights 1 needs to be increased. When the scaffold is expanded, the length of the horizontal bar formed by splicing the horizontal bar 202 and the diagonal bar formed by splicing the diagonal bar 203 can be adjusted after loosening the splicing hoop 204. The two ends of the diagonal bar can swing along the ends of the connecting upright 201 and the supporting column 205 through the splicing bolt 207. After the splicing horizontal bar 202 and the splicing diagonal bar 203 are adjusted to the appropriate position, they are fixed by the splicing hoop 204, thereby strengthening the bottom of the mobile scaffold. By actively increasing the bottom support area of the scaffold, the scaffold can remain stable even after it is raised, effectively improving the stability and safety of the scaffold.
[0042] When it is necessary to inspect the condition of the scaffolding, the connecting disc 302 and its components are snapped onto the end of the splicing diagonal bar 203 by the splicing plug 301. Then, the tilt angle of the connecting block 304 is adjusted by the splicing arc seat 303, so that the infrared distance sensor 305 can be horizontally installed at the end of the splicing diagonal bar 203. When the scaffolding shakes, it will cause the splicing diagonal bar 203 to swing, which will cause the infrared distance sensor 305 to tilt and swing. When the infrared distance sensor 305 swings, it will detect the change in the distance between the bottom surface and the ground, and then the flashing of the alarm indicator light 306 will remind the scaffolding that it has slipped, so that the staff can find and eliminate the problem of the scaffolding in time, which will further improve the safety of the scaffolding.
[0043] When adjusting the auxiliary splicing horizontal bars 202 and splicing diagonal bars 203, after loosening the splicing hoop 204, the sides of the splicing horizontal bars 202 and splicing diagonal bars 203 can be limited by the connecting inclined plate 401, and the splicing horizontal bars 202 and splicing diagonal bars 203 can be flexibly bound by the connecting elastic band 403. Then, the sides of the connecting inclined plate 401 are reinforced by the support strip 402 to prevent misalignment between the splicing horizontal bars 202 and splicing diagonal bars 203, thereby effectively improving the stability of each component during the scaffolding adjustment process.
