The wheel carrier 210 is mounted on the bracket leg of the ladder body and can rotate 360 degrees around the central axis 215. The axis 211 of the driven wheel 212 is fixed on the wheel frame. The wheel carrier and the driven wheel structure and the existing universal wheel The structure is roughly the same. The self-locking mechanism mainly comprises a DC electromagnetic coil 221, a non-magnetized ferromagnetic core 222, a spring 223, a toothed disc 231, a carrier 230, two circular gears 226, two metal brake stops 225 and a strip. The movable rod 224 is composed of. The DC electromagnetic coil 221 is disposed in the bracket leg. The non-magnetized ferromagnetic core 222 is disposed in the DC electromagnetic coil 221 and can move up and down. The spring 223 is sleeved in the non-magnetized ferromagnetic core 222 or disposed on the non-magnetized ferromagnetic core. The upper end surface of the core 222. The toothed disc 231 is fixed to the wheel carrier 210, and the carrier 230 is fixed to the non-magnetized ferromagnetic core 222. When the non-magnetized ferromagnetic core moves downward, the carrier and the toothed disc can mesh with each other. Two circular gears 226 are respectively fixed on two sides of the driven wheel 212, and two metal brake stopping rods 225 are respectively disposed above the circular gear 226, and one ends of the two metal brake stopping rods 225 are fixed on the rotating shaft 227. The rotating shaft 227 is erected in the wheel frame, so that the two metal brake stopping rods can rotate around the rotating shaft at the same time; the other ends of the two metal brake stopping rods 225 have teeth 2251 movablely engaged with the circular gear 1. In addition, a connecting rod 228 is disposed between the rods of the two metal brake bars, and the upper end of the movable rod 224 is hinged to the lower end of the non-magnetized ferromagnetic core, and the lower end is hinged to the connecting rod 228. Tooth The teeth on the frame are the same modulus as the teeth on the toothed disc. The teeth on the metal brake stop are the same modulus as the teeth on the circular gear, and the tooth engagement angle between the carrier and the toothed disc, and the metal brake The tooth engagement angle between the stop rod and the circular gear is positive with the absolute vertical line, that is, there is no phenomenon of undercut and seizure.
上述从动行走轮组件 2的自锁机构的工作过程如下: 当梯子主体 10处于静止状态时,直 流电磁线圈 221无电流通过而不工作, 则非磁化铁磁芯 222在弹簧 223的弹力作用下处于下 止位, 非磁化铁磁芯 222上的齿架 230与轮架 210上的齿盘 231啮合而使轮架 210不能绕中 心轴 215转动; 同时, 由于非磁化铁磁芯 222处于下止位, 位于其下端的活动杆 224亦推动 金属刹停杆 225绕转轴 227向下转动使其上的齿 2251与从动轮 212两侧的圆形齿轮 226啮合 而使从动轮不能绕轴心 211转动, 由于轮架和从动轮同时不能转动, 即从动行走轮组件处于 锁定状态。 当直流电磁线圈 221有电流通过而工作产生磁力, 则非磁化铁磁芯 222受该磁力 作用并克服弹簧 223的弹力而向上移动至上止位,齿架 230与齿盘 231解除啮合而使轮架 210 可绕中心轴 215作 360度自由旋转; 同时, 非磁化铁磁芯的上移亦带动活动杆 224上移使之 拉动金属刹停杆绕转轴 227向上转动,金属刹停杆上的齿 2251与圆形齿轮 226解除啮合而使 从动轮可绕轴心 211 自由转动, 由于轮架和从动轮均可同时转动, 即从动行走轮组件处于解 锁状态, 则从动行走轮组件可根据电动行走轮组件 1的动作作出相应的从动配合。  The working process of the self-locking mechanism of the driven traveling wheel assembly 2 is as follows: When the ladder main body 10 is in a stationary state, the DC electromagnetic coil 221 has no current to pass without operation, and the non-magnetized ferromagnetic core 222 is under the elastic force of the spring 223. In the lower stop position, the carrier 230 on the non-magnetized ferromagnetic core 222 engages with the spur 231 on the wheel carrier 210 to prevent the wheel carrier 210 from rotating about the central axis 215; meanwhile, since the non-magnetized ferromagnetic core 222 is at the bottom stop The movable rod 224 at the lower end thereof also pushes the metal brake stop rod 225 to rotate downward about the rotating shaft 227 such that the upper teeth 2251 mesh with the circular gears 226 on both sides of the driven wheel 212 so that the driven wheel cannot rotate around the axis 211. Since the wheel carrier and the driven wheel cannot rotate at the same time, the driven traveling wheel assembly is in a locked state. When the DC electromagnetic coil 221 has a current to pass and work to generate a magnetic force, the non-magnetized ferromagnetic core 222 is moved upward by the magnetic force against the elastic force of the spring 223 to the upper stop position, and the carrier 230 is disengaged from the toothed disc 231 to make the wheel carrier 210 can rotate 360 degrees around the central axis 215; at the same time, the upward movement of the non-magnetized ferromagnetic core also drives the movable rod 224 to move upward to pull the metal brake stop rod to rotate upward about the rotating shaft 227, and the teeth 2251 on the metal brake stopping rod Disengagement from the circular gear 226 allows the driven wheel to freely rotate about the axis 211. Since the wheel carrier and the driven wheel can rotate simultaneously, that is, the driven traveling wheel assembly is in an unlocked state, the driven traveling wheel assembly can be electrically driven. The action of the wheel assembly 1 makes a corresponding follower fit.

The line outputs a command signal to the DC motor and the DC solenoid, and the DC motor and the DC solenoid act accordingly according to the command signal. The command signals mainly include causing the two DC motors to rotate, reverse and change the rotational speed independently or synchronously, so that the ladder body is directionally moved, the moving speed and the direction are controlled; for the two DC electromagnetic coils The command signal is mainly to energize and de-energize the two DC electromagnetic coils at the same time, and it is required that after the button group issues an action command, the DC electromagnetic coil is energized by a full voltage of 0.5 seconds earlier than all the actions. The indicator light 320 adopts a red light-emitting diode. When the integrated circuit IC detects that the battery voltage is insufficient, in order to avoid excessive discharge and damage the battery, the indicator light will be illuminated to remind the user to charge the battery.
