[0039] Among them, the transmission assembly 300 includes a transmission screw 310 arranged perpendicular to the slide rail 100, a driving screw 320 that drives the transmission screw 310 to rotate when rotating, a speed change system connecting the driving screw 320 and the driving gear 150, and two linkage components corresponding to the lock box 200.

[0040] The two linkage components are symmetrically arranged on both sides of the slide rail 100, and each linkage component includes a cooperative transmission rod 330, a cooperative driving gear 340, a cooperative transmission gear 350 meshing with the cooperative driving gear 340, and an O-shaped gear groove 360 provided on the outer wall of the corresponding locking box 200. One end of the cooperative transmission rod 330 of the two linkage components is respectively meshed with the two ends of the transmission screw 310 through a cylindrical thread, and the other end is respectively meshed with the corresponding cooperative driving gear 340. When the transmission screw 310 rotates, it moves back and forth axially and alternately engages or separates with the two cooperative transmission rods 330 through a cylindrical thread. The cooperative transmission gear 350 is connected to a coaxially arranged cooperative driving gear 370 through a cooperative shaft 351. The cooperative driving gear 370 is movably arranged in the gear groove 360 and meshes with the gear groove 360.

[0041] Each locking assembly 500 includes a sector gear 510 sleeved on the transmission screw 310, a gear plate 520 meshing with the sector gear 510 and a slider 530 slidingly arranged in the corresponding locking box 200, the gear plate shaft 521 of the gear plate 520 is connected to a crank 540, a connecting rod 550 is hinged between the crank 540 and the slider 530, a V-shaped hole 531 is opened on the slider 530, and a [-shaped groove 560 is provided on the inner wall of the locking box 200, one end of the locking rod 210 is connected to a positioning rod 570, and the positioning rod 570 is connected to a positioning block 580 that passes through the V-shaped hole 531 and is slidably inserted into the [-shaped groove 560; when the transmission screw 310 moves axially and engages or disengages with the two co-operating transmission rods 330 through a cylindrical thread, the sector gears 510 of the two locking assemblies 500 are respectively engaged with or disengaged from the corresponding gear plates 520.

[0042] When the mechanical climbing frame anti-falling and anti-overturning device provided in the embodiment of the present application is used, the housing 110 is fixedly connected to the climbing frame body of the mechanical climbing frame, and the slide rail 100 of the mechanical climbing frame anti-falling and anti-overturning device is extended along the climbing direction of the mechanical climbing frame, so as to utilize the mechanical climbing frame anti-falling and anti-overturning device to prevent the safety hazards caused by the mechanical climbing frame falling due to accidents. When the mechanical climbing frame climbs, it drives the housing 110 to move along the slide rail 100. At this time, the housing 110 drives the connected driving gear 150 to move along the slide groove 120 on the slide rail 100 through the input shaft 400, so as to utilize the slide groove 120 to prevent the mechanical climbing frame from falling due to accidents. The racks 140 provided on the inner walls on both sides drive the driving gear 150 to rotate. When the driving gear 150 rotates, it drives the input shaft 400 and the sun gear 430 in the transmission system connected thereto to rotate around the input shaft 400. When the sun gear 430 rotates, it drives the meshed first planetary gear 440 to rotate, thereby driving the meshed second planetary gear 450 with the first planetary gear 440 to rotate. At the same time, when the sun gear 430 rotates, it pushes the first planetary gear 440 and the second planetary gear 450 to intermittently rotate around the axis of the inner gear ring 420, thereby driving the output shaft 410 to intermittently rotate when the driving gear 150 rotates. The rotation drives the driving screw 320 to rotate. When the driving screw 320 rotates, the transmission screw 310 is rotated through the thread. When the transmission screw 310 rotates, it moves axially to the right and drives the locking box 200 on the left to move a preset distance along the length direction of the slide rail 100 through the linkage component on the left, and the locking component 500 on the left drives the corresponding locking rod 210 to disengage from the corresponding locking hole 130 and move with the locking box 200 for a preset distance. After the locking box 200 stops, it inserts into another locking hole 130. Then the transmission screw 310 moves axially to the left and drives the locking box 200 on the left to move a preset distance. The locking box 200 on the right side moves a preset distance along the length direction of the slide rail 100, and the locking assembly 500 on the right side drives the corresponding locking rod 210 to disengage from the corresponding locking hole 130 and move a preset distance with the locking box 200. After the locking box 200 stops, it is inserted into another locking hole 130. The above process is then repeated to drive the shell 110 to move along the slide rail 100 when the mechanical climbing frame climbs, and drive the two locking boxes 200 to move alternately along the slide rail 100, and keep one or two locking rods 210 inserted in the locking hole 130 on the side wall of the slide rail 100 at any time to lock and prevent falling.

[0043] Specifically, when the mechanical climbing frame climbs, it drives the housing 110 to move along the slide rail 100 to rotate the transmission screw 310, and the left end of the transmission screw 310 is engaged with the auxiliary transmission rod 330 of the left linkage assembly through a cylindrical thread, and the fan gear 510 set on the left end of the transmission screw 310 is engaged with the gear plate 520 of the left locking assembly 500. At this time, the auxiliary transmission rod 330 of the left linkage assembly pushes the transmission screw 310 to move to the right through the cylindrical thread, and the rotation of the transmission screw 310 drives the auxiliary transmission rod 330 of the left linkage assembly to rotate and then drives the corresponding auxiliary driving gear 340 to rotate. The auxiliary driving gear 340 of the left linkage assembly drives the auxiliary transmission gear 350 to rotate, so that the auxiliary transmission gear 350 The auxiliary driving gear 370 coaxially connected with 50 rotates and drives the meshing O-shaped gear groove 360 to move relative to the auxiliary driving gear 370, thereby driving the locking box 200 connected to the gear groove 360 to move along the climbing direction of the mechanical climbing frame, and at the same time, the fan gear 510 sleeved on the left end of the transmission screw 310 drives the gear plate 520 of the left locking assembly 500 to rotate, so that the gear plate shaft 521 of the gear plate 520 drives the crank 540 to rotate, and when the crank 540 rotates, it drives the connecting rod 550 to drive the slider 530 to move along the locking box 200, thereby driving the positioning block 580 to move along the [-shaped groove 560 through the V-shaped hole 531 opened on the slider 530, so that the positioning block 580 moves along the locking rod 210 connected to the positioning rod 570 through the positioning rod 570. [shaped groove 560 moves, thereby driving the locking rod 210 connected to the left locking box 200 to disengage from the corresponding locking hole 130, and then the locking box 200 moves a preset distance along the climbing direction of the mechanical climbing frame and then inserts into another locking hole 130 to re-lock, until the transmission screw 310 moves to the right side to the right end and engages with the auxiliary transmission rod 330 of the right side linkage assembly through the cylindrical thread, and the fan gear 510 sleeved on the right end of the transmission screw 310 engages with the gear plate 520 of the right end side locking assembly 500, at this time, the left end of the transmission screw 310 is disengaged from the auxiliary transmission rod 330 of the left side linkage assembly, and the fan gear 510 sleeved on the left end of the transmission screw 310 is disengaged from the gear plate 520 of the left end side locking assembly 500, and the transmission screw 3 When the cam 10 continues to rotate, according to the same working principle, the right locking box 200 connected to the right gear slot 360 is driven to move along the climbing direction of the mechanical climbing frame through the right linkage assembly, and the locking rod 210 connected to the right locking box 200 is driven to disengage from the corresponding locking hole 130, and then the locking box 200 moves a preset distance along the climbing direction of the mechanical climbing frame and then inserts into another locking hole 130 to be locked again, and then the above process is repeated, so that when the mechanical climbing frame climbs, the housing 110 is driven to move along the slide rail 100 and drive the transmission screw 310 to rotate, and the rotating transmission screw 310 is alternately connected to the linkage assembly and the locking assembly 500 at both ends, thereby driving the two locking boxes 200 to alternately move a preset distance along the length direction of the slide rail 100.When the locking box 200 moves, the corresponding locking rod 210 is driven out of the corresponding locking hole 130, and after moving with the locking box 200 a preset distance, it is inserted into another locking hole 130, thereby ensuring that at any time, one or two locking rods 210 of the locking assembly 500 are inserted into the locking hole 130 for locking. After the locking is stuck, the control mechanism can be triggered to control the climbing mechanism of the mechanical climbing frame to cut off the power supply and stop the climbing action, thereby ensuring the safety of the mechanical climbing frame and reducing the impact force on the mechanical climbing frame.

[0044] Among them, when the left end of the transmission screw 310 is engaged with the cooperative transmission rod 330 of the left linkage assembly through a cylindrical thread, the transmission screw 310 provides power transmission to the cooperative drive gear 370 of the left linkage assembly. At this time, since the transmission screw 310 and the cooperative transmission rod 330 are engaged through the cylindrical thread, the cooperative drive gear 370 has no displacement relative to the transmission screw 310, so that the rotation of the cooperative drive gear 370 drives the corresponding locking box 200 to move via the gear groove 360. When the left end of the transmission screw 310 is separated from the cooperative transmission rod 330 of the left linkage assembly, the transmission screw 310 cannot provide power for the cooperative transmission rod 330 of the left linkage assembly, and the left locking box 200 cannot move because the locking rod 210 of the left locking box 200 is inserted into the corresponding locking hole 130 and locked. However, at this time, the mechanical climbing frame drives the shell 110 to move along the slide rail 100, and makes the cooperative drive gear 370 of the left linkage assembly follow the movement of the shell 110, so that the cooperative drive gear 370 of the left linkage assembly will move to another half circle in the corresponding gear groove 360 to wait until the left end of the transmission screw 310 is re-engaged with the cooperative transmission rod 330 of the left linkage assembly through the cylindrical thread, driving the left locking box 200 to move along the slide rail 100.

[0045] By setting up a speed change system for periodically driving the driving screw 320 to change its rotation speed when the driving gear 150 rotates, the linear power provided by the driving gear 150 when it rotates can be converted into a fluctuating power with a rate similar to a sine curve through the characteristics of the planetary gear set. At this time, since the action rate of the crank 540, the connecting rod 550 and the slider 530 of the locking assembly 500 is also a fluctuating curve similar to a sine curve, the two sine-like waves are superimposed, which can make the action rate superimposed to the maximum value when the locking rod 210 is inserted into or removed from the locking hole 130, so that the insertion and extraction action part takes up the least time in one action cycle. When the mechanical climbing frame drives the housing 110 to fall rapidly, the rotation rate of the driving gear 150 exceeds the preset value. At this time, the fluctuation curve of the speed change system shows a "compression" trend. The direct consequence of superimposing the action curves of the crank 540, connecting rod 550 and slider 530 of the locking assembly 500 is that the locking time increases within one action cycle. At this time, the linkage assembly has not been superimposed with the action curves of the crank 540, connecting rod 550 and slider 530, so that the linkage assembly drives the locking box 200 to move when the locking rod 210 is not completely pulled out, causing the entire system to be locked for protection against falling alarm.

[0046] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
