The invention belongs to the technical field of lifting tables, and particularly relates to a guide rail type lifting table. Articles are placed on a lifting plate, then hydraulic cylinders are used for driving fixing columns to move upwards, then chains are used for pulling up connecting frames under the action of bearings, then the connecting frames drive the lifting plate to move upwards, then the hydraulic cylinders drive the fixing columns to move downwards, and therefore the lifting plate can be put down, and the lifting operation of the lifting table is completed. In the process that the lifting plate moves downwards during object carrying, when the lifting plate makes contact with a fixing base, U-shaped frames make contact with the top end of the fixing base firstly, then the fixing base supports fixing plates under the action of supporting elastic force of supporting springs, then the descending impact force of rotation wheels in first sliding grooves is reduced, the lifting table can be well protected, the use performance of the guide rail type lifting table is guaranteed, the descending impact force of a supporting platform from a high layer after loading can be weakened, and a good damping effect can be achieved.
本发明属于升降台技术领域,尤其为一种导轨式升降台。本发明通过设置将物品放置在升降板上,然后利用液压缸带动固定柱向上移动,然后利用链条在轴承的作用下将连接架向上拉起,然后连接架带动升降板向上移动,然后通过液压缸带动固定柱向下移动,从而可以将升降板放下,从而完成该升降台的升降操作,在升降板载物的时候向下移动的过程中,在升降板接触到固定座上时U形架首先接触到固定座顶端,然后固定座通过支撑弹簧的支撑弹力作用下对固定板进行支撑,从而降低了转动轮在第一滑动槽中下降的冲击力,可以较好的对升降台进行防护,保证该导轨式升降台的使用性能,可以减弱支撑平台载物后从高层下降的冲击力,可以起到较好的减振效果。
