A telescopic propulsion plate 203 is threadedly connected to the first screw rod 202, and one side of the telescopic propulsion plate 203 is fixedly connected to one end of a plurality of elastic telescopic rods 204. The other ends of the plurality of elastic telescopic rods 204 are all fixedly connected to a connecting block 205. The top ends of the plurality of connecting blocks 205 are respectively fixedly connected to a first extension plate 2061, a second extension plate 2062 and a bearing plate 206. 61 is arranged close to the second expansion plate 2062, and three supporting plates 206 are arranged on the side where the first expansion plate 2061 and the second expansion plate 2062 are away from each other. The top ends of the supporting plate 206, the first expansion plate 2061 and the second expansion plate 2062 are in the same horizontal plane, and the lower side of the supporting plate 206 is provided with a first telescopic rod 207, and the first telescopic rod 207 is against the supporting plate 206, the first expansion plate 2061 and the second expansion plate 2062. The first telescopic rod 207 is used to support the supporting plate 206, the first expansion plate 2061 and the second expansion plate 2062, and the ends of the supporting plate 206, the first expansion plate 2061 and the second expansion plate 2062 are rotatably connected with rollers 208. A driving mechanism is arranged on the chassis 1, and the driving mechanism is used to drive the chassis 1 to move, so that the chassis 1 can move in a plane and across floors. A braking mechanism is arranged on the chassis 1, and the braking mechanism is used to brake the driving mechanism to keep it stable, so that the chassis 1 will not be displaced during stair construction.

[0022] When the entire device is moved to the construction position, the front end of the entire device is directed toward the construction wall. When there is an obstacle at the front end of the entire device, the front end of the entire device cannot approach the construction wall, and the construction personnel are unable to perform construction on the construction wall due to the distance between them and the construction wall. At this time, the roller 208 is at a certain distance from the construction wall, and the first drive motor 201 is started. The output shaft of the first drive motor 201 drives the first screw rod 202 to rotate. The rotation of the first screw rod 202 drives the telescopic propulsion plate 203 to move to the side away from the first drive motor 201. The telescopic propulsion plate 203 drives the multiple elastic telescopic rods 204 to move away from the first drive motor 20 1, the plurality of elastic telescopic rods 204 drive the adjacent connecting blocks 205 to move, the connecting blocks 205 drive the carrying plate 206, the first extension plate 2061 and the second extension plate 2062 to move, the carrying plate 206, the first extension plate 2061 and the second extension plate 2062 slide on the first telescopic rod 207, the first telescopic rod 207 provides support for the carrying plate 206, the first extension plate 2061 and the second extension plate 2062, and at the same time, the carrying plate 206, the first extension plate 2061 and the second extension plate 2062 drive the adjacent rollers 208 to move, the carrying plate 206, the first extension plate 2061 and the second extension plate 2062 When the adjacent rollers 208 are driven by the support plate 2062 to move, the front ends of the support plate 206, the first extension plate 2061 and the second extension plate 2062 are in the same horizontal plane. When the construction wall surface is a plane, the support plate 206, the first extension plate 2061 and the second extension plate 2062 drive the adjacent rollers 208 to move so as to fit with the construction wall surface, and the front ends of the support plate 206, the first extension plate 2061 and the second extension plate 2062 can maintain the same horizontal plane. Then, the first driving motor 201 is turned off, and the output shaft of the first driving motor 201 no longer drives the first screw rod 202 to rotate. After the first screw rod 202 stops rotating, the extension rod 202 is The retractable propulsion plate 203 remains stable, and after the retractable propulsion plate 203 stops moving, the multiple elastic telescopic rods 204 thereon remain stable, and after the multiple elastic telescopic rods 204 stop moving, the adjacent connecting blocks 205 thereon remain stable, and after the connecting blocks 205 stop moving, the adjacent supporting plates 206, the first extension plate 2061, and the second extension plate 2062 thereon remain stable, and the supporting plates 206, the first extension plate 2061, and the second extension plate 2062 drive the adjacent rollers 208 to remain stable, and the movement of the supporting plate 206 can drive the construction workers to shorten the distance between them and the construction wall, so that the construction workers can work more conveniently. When the construction wall is an arc-shaped surface, the bearing plate 206, the first extension plate 2061 and the second extension plate 2062 drive the adjacent rollers 208 to move and cannot fit with the arc-shaped construction wall. When one of the rollers 208 abuts against the arc-shaped wall, there is still a gap between the other rollers 208 and the arc-shaped wall. The rollers 208 abutting against the arc-shaped wall restrict the adjacent bearing plate 206, the first extension plate 2061 or the second extension plate 2062 from moving.At this time, the restricted carrying plate 206, the first expansion plate 2061 or the second expansion plate 2062 makes the adjacent connection block 205 unable to move, and the connection block 205 is restricted so that the adjacent elastic telescopic rod 204 cannot move. The elastic telescopic rod 204 shrinks after being restricted. At this time, the other rollers 208 that are not in contact with the curved wall can continue to move, and the output shaft of the first drive motor 201 continues to drive the first screw rod 202 to rotate, and the first screw rod 202 continues to rotate to drive the telescopic propulsion plate 203 to move away from the first drive motor 201. The telescopic propulsion plate 203 continues to drive the multiple elastic telescopic rods 204 to move away from the first drive motor 201. The multiple elastic telescopic rods 204 continue to drive the adjacent connection blocks 205. The connecting block 205 continues to drive the adjacent carrying plate 206, the first expansion plate 2061 or the second expansion plate 2062 to move, and the carrying plate 206, the first expansion plate 2061 or the second expansion plate 2062 continues to move on the first telescopic rod 207. When all the rollers 208 are against the wall, the first driving motor 201 is turned off, and the output shaft of the first driving motor 201 no longer drives the first screw 202 to rotate. After the first screw 202 stops rotating, the telescopic propulsion plate 203 remains stable. After the telescopic propulsion plate 203 stops moving, the multiple elastic telescopic rods 204 thereon remain stable. After the multiple elastic telescopic rods 204 stop moving, the adjacent connecting block 205 thereon remains stable. After the connecting block 205 stops moving The adjacent carrying plate 206, the first expansion plate 2061 and the second expansion plate 2062 are kept stable, and the carrying plate 206, the first expansion plate 2061 and the second expansion plate 2062 drive the roller 208 to keep stable. After the construction personnel complete the work, they start the first driving motor 201, and the first driving motor 201 drives the first screw 202 to rotate. The rotation of the first screw 202 drives the telescopic propulsion plate 203 to move and reset. The telescopic propulsion plate 203 drives the multiple elastic telescopic rods 204 to move and reset. The multiple elastic telescopic rods 204 drive the adjacent connecting blocks 205 to move and reset. The connecting blocks 205 drive the adjacent carrying plates 206, the first expansion plates 2061 and the second expansion plates 2062 to move and reset. The carrying plates 206, The first extension plate 2061 and the second extension plate 2062 move and reset on the first telescopic rod 207, and at the same time, the supporting plate 206, the first extension plate 2061 and the second extension plate 2062 drive the adjacent rollers 208 to move, and the elastic telescopic rod 204 is released and reset. After the supporting plate 206, the first extension plate 2061 and the second extension plate 2062 are reset, the front ends of the supporting plate 206, the first extension plate 2061 and the second extension plate 2062 are in a parallel state, thereby realizing the supporting plate 206, the first extension plate 2061 and the second extension plate 2062 of the extension mechanism to extend outward and reset, and the supporting plate 206, the first extension plate 2061 and the second extension plate 2062 can be dislocated and moved by multiple elastic telescopic rods 204.The bearing plate 206, the first extension plate 2061 and the second extension plate 2062 are adapted to the special-shaped wall surface. The driving mechanism can drive the chassis 1 to move on the flat road surface and stairs, which can make the movement of the entire device more convenient. When the chassis 1 stays on the stairs for construction, the brake mechanism can brake the driving mechanism to keep the driving mechanism stable. The driving mechanism keeps stable, which can enable the chassis 1 to drive the entire device to stay stably on the stairs.

The translation track provides support for the first sub-plate, thereby completing the first extension plate 2061 driving the adjacent first sub-plate to reset.

[0039] When the top areas of the carrying plate 206, the first expansion plate 2061 and the second expansion plate 2062 need to be reduced, the electric push rod 902 is started, and the telescopic end of the electric push rod 902 drives the first articulated frame 903 to retract to the side away from the telescopic propulsion plate 203. The first articulated frame 903 is forced to drive the adjacent telescopic propulsion plates 203 to move closer to each other, and the telescopic propulsion plates 203 drive the adjacent sliding plates 905 to slide closer to each other on the support plate 2. The sliding plate 905 on the left drives the elastic unlocking rod of the limit assembly to move and reset, and the elastic unlocking rod moves and The elastic push rod is squeezed and the elastic push rod is forced to slide rightward to reset. After the elastic push rod slides rightward, it no longer restricts the positioning rod. After the positioning rod is freed from the restriction of the elastic push rod, the first hinged frame 903 can move downward to reset. At the same time, the telescopic propulsion plate 203 drives the adjacent first telescopic rod 207 to retract. At the same time, the third slide rail 907 on the telescopic propulsion plate 203 drives the elastic support block 908 therein to move. The elastic support block 908 drives the second telescopic rod 909 to retract. The second telescopic rod 909 drives several sliding blocks 910 thereon to retract and move. 910 squeezes the adjacent first slide groove 911 to drive the adjacent carrying plate 206, the first expansion plate 2061 and the second expansion plate 2062 to move closer to each other, the first expansion plate 2061 and the second expansion plate 2062 drive the adjacent second hinge frame 1005 and the third hinge frame 1008 to move closer to each other, the second hinge frame 1005 drives the adjacent third telescopic rod 1003 to contract, the contraction of the third telescopic rod 1003 drives the first hinge plate 1002 to drop downward, the first hinge plate 1002 drives the positioning rod to move downward and reset, and at the same time the third hinge frame 1008 is The connecting frame 1008 drives the adjacent fourth telescopic rod 1007 to contract, and the fourth telescopic rod 1007 contracts and drives the second hinged plate 1006 to fall, and the first hinged plate 1002 no longer squeezes the sliding track to make the front bottom end of the lifting plate 1001 fall downward, and at the same time, the second hinged plate 1006 drives the rear bottom end of the lifting plate 1001 to fall downward, and the lifting plate 1001 falls upward and resets to the initial position, and the supporting plate 206, the first expansion plate 2061 and the second expansion plate 2062 fit tightly again, thereby completing the reset of the expansion mechanism and the limit assembly.

[0040] When the carrying plate 206 and the first extension plate 2061 and the second extension plate 2062 are dislocated and moved, the blocking frame 1101 thereon follows the adjacent carrying plate 206, the first extension plate 2061 or the second extension plate 2062 to move dislocated, and at this time, the universal telescopic rod 1102 between the blocking frames 1101 rotates and extends with the connection point of the two adjacent blocking frames 1101 as the center of the circle, thereby enabling the blocking frame 1101 to always be in a connected state, and when the carrying plate 206 and the first extension plate 2061 and the second extension plate 2062 are reset and moved, the blocking frame 1101 thereon follows the adjacent carrying plate 206, the first extension plate 2061 or the second extension plate 2062 to reset and move, and at this time, the universal telescopic rod 1102 between the blocking frames 1101 rotates and contracts with the connection point of the two adjacent blocking frames 1101 as the center of the circle, thereby completing the reset of the universal telescopic rod 1102.
