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

Working principle: in the construction process, the first motor 205 is started, the 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 with the first rack 203, so that the first rotating gear 204 toggles the first rack 203 to enable the first rack 203 to slide upwards along the carriage 201 with the door 202, a constructor can enter the carriage 201, and then the first motor 205 rotates reversely to enable the door 202 to fall. At this time, the motor 102 fixedly installed on the standard joint 101 is started, the winding roller is driven by the motor 102 to wind the rope 104, so that the rope 104 drives the car 2 fixedly installed on the rope 104 to move upwards along the standard joint 101 integrally, and the constructor is sent to the construction height. During the ascending process of the car 2, the gear IV 401 rotatably mounted on the car body 201 rolls stably along the rack VI 402 fixedly mounted on the standard joint 101, when the rope 104 breaks or the motor 102 is damaged, the rope 104 does not hang the car body 201 any more, the car body 201 falls down along the standard joint 101 under the action of gravity, at this time, the gear IV 401 also moves downwards, the rotation speed of the gear IV gradually increases, the rotation speed of the protection wheel 403 coaxially connected with the gear IV 401 increases, so that the push rod 404 slidably mounted in the protection wheel 403 is thrown out under the action of centrifugal force, the sliding part of the push rod 404 contacts with the locking rod 405 and pushes the locking rod 405, so that the locking rod 405 slides away from the sliding plate 406, the locking rod 405 does not limit the sliding plate 406 any more, the locking post 407 and the sliding plate 406 are pushed to the side close to the mounting frame 1 under the action of the elasticity of the first reset spring 408 until the locking post 407 is inserted into the standard joint 101, the locking post 407 is blocked, and thus the second reset post 201 is mounted on the car body 201 and the second cage body 201 is stopped under the action of the second reset spring 2, and the car body is prevented from falling down by the constructor unexpected means.

When the construction place needs to be replaced, the installation frame 1 and the car 2 need to be horizontally moved integrally, so that the car 201 falls above the upper supporting plate 301, and the constructor comes out of the car 201. The carriage 201 falling onto 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 that the rack five 318 also slides downwards, the gear three 314 is meshed with the rack five 318, so that the gear three 314 rotates on the upper support plate 301, the gear three 314 is meshed with the rack four 315 at the same time, so that the rack four 315 slides upwards along the upper support plate 301 with the limiting rod 316, the lower end of the limiting rod 316 is pulled 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 in the process, the reset spring four has the function of facilitating resetting of the moving plate 313.

Then, the four supporting cylinders two 309 fixedly installed on the lower supporting plate 308 are contracted, so that the height of the lower supporting plate 308 is lowered, and the height of the displacement motor and the gear two 311 on the lower supporting plate 308 is lowered, so that the gear two 311 falls from the position right above the rack two 306 to the position contacting the rack two 306 and is engaged with each other, and the telescopic guide rod 307 is pulled apart in the vertical direction in the process because the telescopic guide rod 307 is telescopic. Then a displacement motor fixedly arranged on the lower supporting plate 308 is started, the gear II 311 is driven to rotate by the displacement motor, the gear II 311 is meshed and matched with the rack II 306, the rack II 306 is fixedly arranged on the upper supporting plate 301, the upper supporting plate 301 is fixed on the ground by the first supporting cylinder 302, the rotating gear II 311 carries the displacement motor and the lower supporting plate 308 to horizontally move along the long side direction of the rack II 306, after the lower supporting plate 308 is moved to a proper position for the next construction, the displacement motor is closed, the second supporting cylinder 309 and the first supporting cylinder 302 are started, the extending end of the second supporting cylinder 309 extends, thus the height of the second supporting plate 308 is increased, the gear II 311 is separated from the rack II 306 and reaches the right above the rack II 306, the extending end of the first supporting cylinder 302 is contracted, the height of the upper supporting plate 301 is reduced, in this way, the third rack 310 fixedly installed on the lower support plate 308 contacts and engages with the worm 305 rotatably installed below the upper support plate 301, the telescopic guide rod 307 which is pulled to slide out gradually contracts, then the second motor 304 is started, the worm 305 fixedly installed on the output shaft of the second motor 304 rotates, the worm 305 engages with the third rack 310, the third rack 310 and the lower support plate 308 are fixed, so that the second motor 304 horizontally moves with the upper support plate 301 and the mounting frame 1 and the car 2 above the upper support plate 301, and the telescopic guide rod 307 plays a role of guiding in the horizontal position during 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 that before the movement of the lower support plate 308, thus completing the integral horizontal movement.
