(1) Two turntables 53 in two screw limiting assemblies arranged on the inner side surfaces of the side plates 41 positioned on two sides of the limiting base 51 are controlled to rotate by a stepping motor, in the rotating process of the turntables 53, adjusting screws 54 arranged between the two turntables 53 also rotate along with the turntables, and meanwhile, the adjusting screws 54 are arranged in horizontal bar-shaped adjusting holes 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 lifting and lowering of the limit base 51 drives the lifting of the two jaw limit assemblies 57 mounted in the jaw mounting groove 52 on the rear end surface of the limit base 51, so as to control whether the two jaw limit assemblies 57 are engaged with the meshing teeth on the periphery of the large gear 40.
(3) The rotation of the two turntables 53 can control the displacement of the pivoted arm 55 hinged on the adjusting screw 54, thereby realizing the expansion degree of the telescopic screw 56 hinged at the rear end of the pivoted arm 55, and further controlling whether the telescopic screw 56 is engaged with the meshing teeth on the periphery of the large gear 40.
As shown in fig. 8, this state is the first state of the cooperation of the large gear 40 and the large gear limiting device 5, and is suitable for the assembly adjustment between the wall-attached support 4 and the slide rail device 3. At this time, the adjusting screw 54 is positioned at the leftmost end of the horizontal bar-shaped adjusting hole 531. At this time, the arm 55 pulls the expansion screw 56 to retract to the maximum, and the expansion screw 56 is disengaged from the meshing teeth on the outer periphery of the large gear 40. Simultaneously, two claw limiting assemblies 57 mounted on the rear end face of the limiting base 51 are in a disengaged state with the meshing teeth on the periphery of the large gear 40. At this time, the meshing teeth on the periphery of the large gear 40 interfere with the slide rail supporting 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 conveniently adjusted.
As shown in fig. 9, this state is a second state in which the large gear 40 is engaged with the large gear stopper 5, and is suitable for lowering the frame 1. This state is that the turntable 53 is rotated counterclockwise by 90 ° on the basis of the first state, and in this process, the adjusting screw 54 is moved to the center position of the horizontal bar-shaped adjusting hole 531, and the swivel arm 55 pushes the telescopic screw 56 to gradually extend forward, but the telescopic screw 56 is still in a disengaged state with the meshing teeth on the outer periphery of the large gear 40.
In the second state, the jaw limiting assembly 57 mounted above the rear end surface of the limiting base 51 is in a meshed state with the meshing teeth on the periphery of the large gear 40, and the jaw limiting assembly 57 mounted below the rear end surface of the limiting base 51 is in a disengaged state with the meshing teeth on the periphery of the large gear 40. At this time, the meshing teeth on the outer periphery of the large gear 40 interfere with the rail struts 34 on the rail device 3, and the large gear 40 can only rotate clockwise, that is, the rail device 3 and the climbing frame 1 can only descend slowly. At this time, if the slide rail device 3 and the climbing frame 1 fall off and automatically lose the control of the lifting mechanism 2 to fall freely, the large gear 40 rotates too fast, the limit post 575 contacted with the meshing tooth of the large gear 40 is easy to bounce by collision, and the limit pin two 522 can play a certain limit role on the bouncing limit rotating rod 571; meanwhile, the spring 572 can pull back the limit rotating rod 571, and then the limit posts 575 on the limit rotating rod 571 collide and clamp the meshing teeth of the large gear 40 again and play a certain limiting role on the rotation of the large gear 40. If the slide rail device 3 and the climbing frame 1 slowly descend, the large gear 40 slowly rotates, and the limit posts 575 on the limit rotating rod 571 can interfere with the meshing teeth of the large gear 40 one by one without separation, and the clockwise rotation of the large gear 40 is not affected.
As shown in fig. 10, this state is the third state of the cooperation of the large gear 40 and the large gear limiting device 5, and is suitable for the fixed locking between the wall-attached support 4 and the slide rail device 3. The state is that the turntable 53 rotates 90 degrees counterclockwise based on the second state, in the process, the limit base 51 gradually rises, and the adjusting screw 54 finally moves to the rightmost end of the horizontal bar-shaped adjusting hole 531; the rotating arm 55 pushes the telescopic screw rod 56 to gradually extend to the maximum extent, and finally the clamping groove 562 arranged at the rear end of the telescopic screw rod 56 is in a clamping state with the meshing teeth on the periphery of the large gear 40; simultaneously, the claw limiting assemblies 57 arranged above the rear end surface of the limiting base 51 are gradually separated from the meshing teeth on the periphery of the large gear 40, and finally, the two claw limiting assemblies 57 arranged on the rear end surface of the limiting base 51 are in a separation state from the meshing teeth on the periphery of the large gear 40.
In this third state, the two expansion 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 slide rail device 3 are fixed and immovable, and the wall-attached support 4 is locked and fixed at a proper position on the slide rail device 3.
As shown in fig. 11, this state is a fourth state in which the large gear 40 is engaged with the large gear stopper 5, and is suitable for the ascent of the climbing frame 1. The state is that the turntable 53 rotates 90 degrees counterclockwise based on the third state, in the process, the limit base 51 gradually descends, the adjusting screw 54 moves to the center position of the horizontal bar-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 claw limiting assembly 57 mounted below the rear end surface of the limiting base 51 is in a meshed state with the meshing teeth on the periphery of the large gear 40, and the claw limiting assembly 57 mounted above the rear end surface of the limiting base 51 is in a separated state with the meshing teeth on the periphery of the large gear 40. At this time, the meshing teeth on the outer periphery of the large gear 40 interfere with the rail struts 34 on the rail device 3, and the large gear 40 can only rotate counterclockwise, that is, the rail device 3 and the climbing frame 1 can only slowly rise. At this time, if the slide rail device 3 and the climbing frame 1 fall off and automatically lose the control of the lifting mechanism 2 to fall freely, the limit post 575 on the limit rotating rod 571 can be clamped in the meshing teeth of the large gear 40, and the limit rotating rod 571 is limited by the limit pin 521, so that the large gear 40 is prevented from rotating clockwise, and the slide rail device 3 and the climbing frame 1 are limited from moving downwards, so that the falling risk of the climbing frame 1 is reduced. If the slide rail device 3 and the climbing frame 1 slowly go up, the large gear 40 slowly rotates, and the limit posts 575 on the limit rotating rod 571 can interfere with the meshing teeth of the large gear 40 one by one without separation, and the anticlockwise rotation of the large gear 40 is not affected.
The invention relates to a mounting construction method of an attached lifting scaffold, wherein a plurality of slide rail devices 3 are symmetrically arranged on the inner side of a mounted climbing frame 1, a wall attaching support 4 arranged on the slide rail devices 3 is fixed with a building structure layer 6 through bolts, and a plurality of holding wheel assemblies 58 arranged in the wall attaching support 4 are adhered to and held tightly and slide with a slide rail support in the slide rail devices, so that the stability of the climbing frame 1 in the lifting process is conveniently maintained; the rotation control of the large gear 40 is performed through the large gear limiting device 5 arranged inside the rear end of the wall-attached support 4, so that the sliding of the sliding rail device 3 interfering with the large gear 40 is controlled, the sliding rail device 3 and the climbing frame 1 are prevented from accidentally falling off in the lifting process, and the firmness and the safety of the lifting scaffold are improved.
The invention relates to an installation construction method of an attached lifting scaffold, which comprises the steps of building an S1 climbing frame, installing a lifting mechanism S2, assembling an S3 wall-attached support and a sliding rail device, installing a sliding rail device S4, controlling the lifting of an S5 attached lifting scaffold, controlling the descending of an S6 attached lifting scaffold, detaching the S7 attached lifting scaffold and the like, wherein the whole installation construction process of the attached lifting scaffold is completed, and the whole attached lifting scaffold has a compact structure and high firmness; the whole process is simple to operate, good in stability, capable of improving lifting control of the lifting device in the lifting process, reducing falling risks, good in safety, convenient to lift and easy to control, and convenient to meet requirements of high-rise building construction.
