The servo motor 34 is CH/V.

The working principle is as follows:

firstly, the climbing device is pushed by the wheel 54 to move to a specified position, after the climbing device reaches the specified position, the second handle 510 is rotated to drive the screw 511 to rotate, because the inside of the rack block 512 is provided with a thread groove matched with the screw 511, the screw 511 drives the rack block 512 to move when rotating, the rack block 512 drives the gear 58 engaged with the rack block to rotate, the gear 58 drives the worm gears 56 at the two ends of the second rotating shaft 57 to rotate, the two worm gears 56 respectively drive the two worm sleeves 55 engaged with the two worm gears to rotate, because the worm teeth on the outer surfaces of the two worm sleeves 55 are arranged in opposite directions, the two worm sleeves 55 rotate in opposite directions, the two worm sleeves 55 respectively drive the two first rotating shafts 53 to rotate, the first rotating shaft 53 drives the wheel 54 to rotate, the wheel 54 on the two first rotating shafts 53 rotates in opposite directions, the wheel 54 rotates to a horizontal state, and then the rotation of the second handle 510 is stopped, the wheels 54 are accommodated, so that the lower sides of the first limiting block 51 and the second limiting block 52 are in contact with the ground, and the climbing device is supported.

Further, personnel climb climbing pole 73 on cat ladder subassembly 7, climb on the base plate 31 on the platform subassembly 3, in the in-process of climbing, keep off net 74 and can play the guard action to personnel's foot, prevent that personnel's step from stepping on empty, and under cowl 75's effect, can play the guard action to personnel's back, prevent that personnel from taking place the condition of facing backward, personnel from climbing back on the base plate 31, sit on roof 61, rotate handle three 62, make it drive lead screw 63 and rotate, under the transmission of hold-in range two 65, hold-in range two 65 can drive two lead screws 63 and rotate, because the screw hole with lead screw 63 looks adaptation is all seted up in the both sides upper surface intermediate position department of base plate 31, consequently, can drive base plate 31 when two lead screws 63 rotate and reciprocate, make base plate 31 adjust to required height, later stall handle three 62 can.

Further, when a person stands on the base plate 31 and the distance between the base plate 31 and the wall surface is too far, the person firstly steps on the foot lever 473 on the first synchronizing wheel 471 to drive the first synchronizing wheel 471 to rotate, the first synchronizing wheel 471 enables the first synchronizing wheel 472 to drive the first synchronizing wheel 471 to rotate, the first synchronizing wheels 471 respectively drive the rotating discs 48 in the two vertical cylinders 41 to rotate when rotating, the rotating discs 48 drive the adjusting shaft 411 to do eccentric motion when rotating, under the elasticity of the spring 412, the upper end of the adjusting shaft 411 drives the sliding plate 410 to slide downwards to further drive the sliding block 49 to move downwards, the tooth block 413 at the upper end of the sliding block 49 is separated from the tooth block 413 on the winding wheel 43, then the power supply of the servo motor 34 is switched on, the servo motor 34 drives the worm 351 to rotate, the worm 351 drives the two worm wheel discs 352 meshed with the worm wheel 351 to rotate, the two worm wheel discs 352 respectively drive the two adjusting rods 353 to do eccentric motion, under the movable connection of the adjusting rods 353, the two adjusting rods 353 can drive the support plate 33 to slide in the groove 32 on the substrate 31 when moving, so that the support plate 33 can slide out of the groove 32, the distance between the support plate 33 and the wall surface is adjusted, after the adjustment is completed, the power supply of the servo motor 34 is turned off, during the movement of the support 33, the chain 46 is loosened in the winding wheel 43, then the first handle 45 is rotated, the first handle 45 drives the two winding wheels 43 to rotate, so that the chain 46 is tensioned, the platform assembly 3 is well stretched, and after being tensioned, the foot releases the foot bar 473 on the first synchronizing wheel 471, thus, under the elasticity of the spring 412, the spring 412 will restore the slide block 49 to the original position, therefore, the tooth blocks 413 on the sliding blocks 49 are meshed with the tooth blocks 413 on the winding wheels 43, the winding wheels 43 are clamped, the stability of stretching the support plate 33 is improved, and then personnel can stand on the support plate 33 to finish the wall.
