Wherein, in the installation work progress of inserted lift scaffold, the control principle of gear wheel 40 is to gear wheel stop device 5:
(1) Two turntables 53 of two screw limiting assemblies arranged on the inner side surfaces of the side edge plates 41 at two sides of the limiting base 51 are controlled to rotate by a stepping motor, in the rotating process of the turntables 53, an adjusting screw 54 arranged between the two turntables 53 rotates along with the turntables, and meanwhile, the adjusting screw 54 is arranged in a horizontal strip-shaped adjusting hole 531 arranged on the limiting base 51, so that the rotation of the turntables 53 drives the limiting base 51 of the large gear limiting device 5 to ascend and descend.
(2) The ascending and descending of the limiting base 51 drives the two clamping jaw limiting assemblies 57 arranged in the clamping jaw mounting groove 52 on the rear end face of the limiting base 51 to ascend and descend, and further the clamping between the two clamping jaw limiting assemblies 57 and the meshing teeth on the periphery of the large gear 40 can be controlled.
(3) The rotation of the two turntables 53 can control the displacement of the rotating arm 55 hinged on the adjusting screw 54, thereby realizing the extension and retraction degree of the extension and retraction screw 56 hinged at the rear end of the rotating arm 55, and further controlling the engagement between the extension and retraction screw 56 and the meshing teeth on the periphery of the large gear 40.
As shown in fig. 8, this state is a first fit state of the bull gear 40 and the bull gear limiting device 5, and is suitable for assembly adjustment between the wall-attached support 4 and the slide rail device 3. At this time, the adjusting screw 54 is located at the leftmost end of the horizontal bar-shaped adjusting hole 531. At this time, the rotating arm 55 pulls the retractable screw 56 to retract to the maximum extent, and the retractable screw 56 is disengaged from the engaging teeth on the outer periphery of the large gear 40. Meanwhile, two jaw limit components 57 arranged on the rear end face of the limit base 51 are in a disengaged state with the meshing teeth on the periphery of the large gear 40. At this time, the engaging teeth on the periphery of the large gear 40 interfere with the slide rail support rod 34 on the slide rail device 3, and the large gear 40 can also rotate freely, so that the wall-attached support 4 and the slide rail device 3 can move relatively, and the position of the wall-attached support 4 on the slide rail device 3 can be adjusted conveniently.
As shown in fig. 9, this state is a second state of engagement between the large gear 40 and the large gear positioning device 5, and is suitable for lowering the creeper frame 1. In this state, the dial 53 is rotated counterclockwise by 90 ° based on the first state, and in the process, the adjusting screw 54 is moved to the center of the horizontal bar-shaped adjusting hole 531, and the rotating arm 55 pushes the telescopic screw 56 to be gradually extended forward, but the telescopic screw 56 is still in the disengaged state from the engaging teeth on the outer periphery of the large gear 40.
In the second state, the jaw limit component 57 mounted above the rear end face of the limit base 51 is in a meshing state with the meshing teeth on the periphery of the large gear 40, and the jaw limit component 57 mounted below the rear end face of the limit base 51 is in a disengaging state with the meshing teeth on the periphery of the large gear 40. At this time, the engaging teeth on the outer periphery of the large gear 40 interfere with the slide rail support rods 34 on the slide rail device 3, and the large gear 40 can only rotate clockwise, that is, the slide rail device 3 and the creeper frame 1 can only slowly descend. At this time, if the sliding rail device 3 and the climbing frame 1 fall off and automatically lose the control of the lifting mechanism 2 and fall freely, the large gear 40 rotates too fast, the limit post 575 in contact with the meshing teeth of the large gear 40 is easy to bounce due to collision, and the second limit pin 522 can play a certain limit role in the bouncing limit rotating rod 571; meanwhile, the spring 572 can pull back the limiting rotation rod 571, and then the limiting post 575 on the limiting rotation rod 571 bumps and engages with the engaging teeth of the bull gear 40 again, and plays a certain role in limiting the rotation of the bull gear 40. If the sliding rail device 3 and the climbing frame 1 slowly descend, the large gear 40 slowly rotates, and the limiting posts 575 on the limiting rotating rod 571 can interfere with the engaging teeth of the large gear 40 one by one without being separated from each other, and the clockwise rotation of the large gear 40 is not affected.
As shown in fig. 10, this state is a fitting state three of the bull gear 40 and the bull gear limiting device 5, and is suitable for fixing and locking between the wall-attached support 4 and the slide rail device 3. In this state, the turntable 53 rotates 90 degrees again counterclockwise on the basis of the second state, in the process, the limiting base 51 gradually rises, and the adjusting screw 54 finally moves to the rightmost end of the horizontal strip-shaped adjusting hole 531; the rotating arm 55 pushes the telescopic screw 56 to gradually extend forwards to the maximum extent, and finally, the clamping groove 562 arranged at the rear end of the telescopic screw 56 is in a clamping state with the meshing teeth on the periphery of the large gear 40; simultaneously, the spacing subassembly 57 of jack catch of installation above the rear end face of spacing base 51 breaks away from with the engaging tooth on the gear wheel 40 periphery gradually, finally makes two spacing subassemblies 57 of jack catch of spacing base 51 rear end face installation also be in the disengagement state with the engaging tooth on the gear wheel 40 periphery.
In the third state, the two retractable screws 56 are locked with the large gear 40, and the large gear 40 cannot rotate, so that the wall-attached support 4 and the sliding rail device 3 are fixed and immovable, and the wall-attached support 4 is locked and fixed at a proper position on the sliding rail device 3.
As shown in fig. 11, this state is a fourth state of engagement between the large gear 40 and the large gear positioning device 5, and is suitable for raising the creeper frame 1. In this state, the rotating disc 53 rotates 90 ° again counterclockwise based on the third state, in the process, the limiting base 51 gradually descends, the adjusting screw 54 moves to the center position of the horizontal strip-shaped adjusting hole 531 again, the rotating arm 55 pulls the telescopic screw 56 to gradually retract, but the telescopic screw 56 is in a disengaged state with the meshing teeth on the periphery of the large gear 40.
In the fourth state, the jaw limit component 57 mounted below the rear end face of the limit base 51 is in a meshing state with the meshing teeth on the periphery of the large gear 40, and the jaw limit component 57 mounted above the rear end face of the limit base 51 is in a disengaging state with the meshing teeth on the periphery of the large gear 40. At this time, the engaging teeth on the outer periphery of the large gear 40 interfere with the slide rail support 34 on the slide rail device 3, and the large gear 40 can only rotate counterclockwise, that is, the slide rail device 3 and the creeper frame 1 can only slowly rise. At this time, if the sliding rail device 3 and the frame-climbing frame 1 fall off and automatically lose the control of the lifting mechanism 2 and fall freely, the limiting column 575 on the limiting rotating rod 571 can be clamped in the engaging tooth of the large gear 40, and the limiting rotating rod 571 is limited by the limiting pin 521, so that the large gear 40 is prevented from rotating clockwise, the sliding rail device 3 and the frame-climbing frame 1 are limited from moving downwards, and the falling risk of the frame-climbing frame 1 is reduced. If the sliding rail device 3 and the climbing frame 1 slowly move up, the bull gear 40 slowly rotates, and the limit posts 575 on the limit rotating rod 571 can interfere with the engaging teeth of the bull gear 40 one by one without disengaging, and the counterclockwise rotation of the bull gear 40 is not affected.
