Specifically, rack six 402 is fixedly mounted on standard knot 101.

The working principle is as follows: during construction, the first motor 205 is started, an output shaft of the first motor 205 is fixedly connected with the first gear 204, so that the first gear 204 rotates along with the first motor 205, and the first gear 204 is meshed and matched with the first rack 203, so that the first rack 203 is pulled by the rotating first gear 204, the first rack 203 drives the door 202 to slide upwards along the carriage 201, and therefore constructors can enter the carriage 201, and then the first motor 205 rotates reversely to enable the door 202 to fall down. At the moment, the motor 102 fixedly installed on the standard knot 101 is started, the winding roller is driven by the motor 102 to wind the rope 104, and thus the rope 104 can drive the whole car 2 fixedly installed on the rope 104 to move upwards along the standard knot 101, and constructors are conveyed to the construction height. During the ascending process of the car 2, the gear four 401 rotatably mounted on the car body 201 smoothly rolls along the rack six 402 fixedly mounted on the standard knot 101, when the rope 104 is broken or the motor 102 is damaged, the rope 104 does not lift the car body 201 any more, at this time, the car body 201 will accelerate and fall down along the standard knot 101 under the action of gravity, at this time, the gear four 401 will move down, and the rotation speed of the gear four 401 will gradually increase, so that the rotation speed of the protection wheel 403 coaxially connected with the gear four 401 increases, so that under the action of centrifugal force, the push rod 404 slidably mounted in the protection wheel 403 will be thrown out, so that the sliding part of the push rod 404 will contact the lock rod 405 and push the lock rod 405, so that the lock rod 405 slides away from the slide plate 406, so that the lock rod 405 will not limit the slide plate 406, under the action of the elastic force of the return spring one 408, the locking column 407 and the sliding plate 406 are pushed towards one side close to the mounting frame 1 until the locking column 407 is inserted into the standard knot 101, and the locking column 407 is clamped, so that the carriage 201 stops falling down due to the fact that the locking column 407 and the square frame 409 are both mounted on the carriage 201, the protection device 4 mainly serves to protect the car 2 and constructors and prevent accidental falling, and the reset spring two 410 serves to reset the locking rod 405.

When the construction place needs to be changed, the installation frame 1 and the car 2 need to be integrally and horizontally moved, so that the carriage 201 falls above the upper supporting plate 301, and constructors come out of the carriage 201. The carriage 201 falling on the surface of the upper support plate 301 presses the moving plate 313, so that the moving plate 313 slides downwards along the upper support plate 301, the rack five 318 is fixedly mounted on the moving plate 313, so the rack five 318 also slides downwards, and the gear three 314 is meshed with the rack five 318, so the gear three 314 rotates on the upper support plate 301, and the gear three 314 is meshed with the rack four 315 at the same time, so the rack four 315 drives the limiting rod 316 to slide upwards along the upper support plate 301, so that the lower end of the limiting rod 316 is drawn out of the limiting hole 312, namely the limiting rod 316 does not limit the limiting hole 312 and the lower support plate 308 any more, and the reset spring four plays a role in facilitating the reset of the moving plate 313 in the process.

Then, the four second support cylinders 309 fixedly mounted on the lower support plate 308 are contracted, so that the height of the lower support plate 308 is lowered, the height of the displacement motor and the second gear 311 on the lower support plate 308 is lowered, the second gear 311 falls to a position contacting with the second rack 306 from the right above the second rack 306 and is meshed with the second rack, and the telescopic guide rod 307 can be stretched, so that the telescopic guide rod 307 is pulled in the vertical direction in the process. Then, a displacement motor fixedly arranged on a lower support plate 308 is started, a gear II 311 is driven to rotate through the displacement motor, the gear II 311 is meshed with a gear rack II 306 in a matching mode, the gear rack II 306 is fixedly arranged on an upper support plate 301, the upper support plate 301 is fixed on the ground through a supporting electric cylinder I302, the rotating gear II 311 drives the displacement motor and the lower support plate 308 to horizontally move along the long side direction of the gear rack II 306, the lower support plate 308 moves to a proper position for next construction, the displacement motor is turned off, the supporting electric cylinder II 309 and the supporting electric cylinder I302 are started, the extending end of the supporting electric cylinder II 309 extends out, the height of the lower support plate 308 is increased, the gear II 311 leaves the gear rack II 306 and reaches the position right above the gear rack II 306, the extending end of the supporting electric cylinder I302 is contracted, the height of the upper support plate 301 is reduced, and the gear rack III 310 fixedly arranged on the lower support plate 308 and the worm 305 rotatably arranged below the upper support plate 301 are accordingly The contact and the engagement are carried out, the telescopic guide rod 307 which is pulled to slide out gradually contracts, then the motor II 304 is started, the worm 305 fixedly arranged on the output shaft of the motor II 304 rotates, the worm 305 is engaged with the rack III 310, the rack III 310 and the lower support plate 308 are fixed, so that the motor II 304 drives the upper support plate 301 and the mounting rack 1 and the car 2 above the upper support plate 301 to horizontally move, the telescopic guide rod 307 plays a role of guiding in the horizontal position in the moving process until the upper support plate 301 moves to a proper position, namely the relative position of the upper support plate 301 and the lower support plate 308 is the same as the state before the lower support plate 308 moves, and the integral horizontal movement is completed.
