Since the nut in the screw and nut group is sleeved on the screw, there is no problem of falling out of the screw. Car fall problem. However, because the length of the screw has manufacturing limitations, and the excessively long screw will also cause many stress concentration problems on the strength of the material, there is a new patent creation in Taiwan, China No. 543649 to overcome the above problems, but the aforementioned patent uses two groups The production cost of the power source is still high, and it is necessary to control two sets of power sources at the same time, resulting in increased control cost. Furthermore, the transmission mechanism is arranged on the side of the mechanism, which may easily cause the carriage to move deflected and run unstable.

以上本较佳实施例的说明,此外,为了减低现有技术中车厢的偏斜情况,本较佳实施例让该减速机163朝该第一导轨11和该第二导轨12间的中间位置设置,如此一来,能够减低车厢移动偏斜且运行平稳。Above the description of this preferred embodiment, in addition, in order to reduce the deflection of the carriage in the prior art, this preferred embodiment allows the speed reducer 163 to be arranged towards the middle position between the first guide rail 11 and the second guide rail 12 , in this way, it can reduce the movement deflection of the compartment and run smoothly.
接下来,介绍本较佳实施例的使用说明。Next, the description of the use of this preferred embodiment will be introduced.
如欲使该移动体18分别沿着该第一导轨11和该第二导轨12上、下移动,启动该动力装置16中的马达164,经由马达164驱动该减速机163,让该第一驱动部161和该第二驱动部162分别驱动该第一螺帽142和该第二螺杆171转动。To make the mobile body 18 move up and down along the first guide rail 11 and the second guide rail 12, start the motor 164 in the power unit 16, drive the reducer 163 through the motor 164, and let the first drive The part 161 and the second driving part 162 respectively drive the first nut 142 and the second screw 171 to rotate.
由于该第二螺杆171转动,故套接在该第二螺杆171的第二螺帽172沿着该第二螺杆171移动,而固接该第二螺帽172的移动体18,也就随着该第二螺帽172移动。在此同时,该第一螺帽142因转动而沿着该第一螺杆141上、下移动,也带动该升降台15分别沿着该第一导轨11和该第二导轨12移动。As the second screw 171 rotates, the second nut 172 sleeved on the second screw 171 moves along the second screw 171, and the moving body 18 fixedly connected to the second nut 172 also moves along with the second screw 171. The second nut 172 moves. At the same time, the first nut 142 moves up and down along the first screw rod 141 due to rotation, and also drives the lifting platform 15 to move along the first guide rail 11 and the second guide rail 12 respectively.
除上述内容之外,特别要提出来的是,该第一螺杆螺帽组14和该第二螺杆螺帽组17皆具有其导程,在本较佳实施例中,该第一螺杆螺帽组14和该第二螺杆螺帽组17的导程相同,并且该第一螺帽142和该第二螺杆171转速相同。如此造成,该升降台15相对该第一螺杆141的移动距离等于该移动体18相对该第二螺杆171移动距离。当然,也可以设计让该第一螺杆螺帽组14的导程大于该第二螺杆螺帽组17的导程,而这时该第一螺帽142的转速则须小于该第二螺杆171转速。或者是,该第一滚珠螺杆14组的导程小于该第二螺杆螺帽组17的导程,并且该第一螺帽142的转速大于该第二螺杆171转速。In addition to the above, it is particularly proposed that the first screw nut group 14 and the second screw nut group 17 all have their leads. In this preferred embodiment, the first screw nut group The leads of the group 14 and the second screw nut group 17 are the same, and the rotational speeds of the first nut 142 and the second screw 171 are the same. As a result, the moving distance of the lifting platform 15 relative to the first screw 141 is equal to the moving distance of the moving body 18 relative to the second screw 171 . Of course, it is also possible to design the lead of the first screw and nut group 14 to be greater than the lead of the second screw and nut group 17, and at this moment, the rotating speed of the first nut 142 must be smaller than the rotating speed of the second screw 171 . Alternatively, the lead of the first ball screw 14 set is smaller than the lead of the second screw nut set 17 , and the rotational speed of the first nut 142 is greater than the rotational speed of the second screw 171 .
