The invention discloses a four-column type lifting machine capable of lifting 20 tons. The lifting machine comprises four stand columns, the stand columns are fixedly connected with the concrete ground through expansion screws, the tops of the stand columns are fixedly connected with side beams, the right sides of the tops of the side beams are fixedly connected with oil cylinders, and the output ends of the oil cylinders are fixedly connected with connecting plates. According to the four-column type lifting machine, through cooperative use of the stand columns, a front end cross beam, longitudinal beams, a rear end cross beam, the side beams, a boarding plate, the oil cylinders, a control cabinet, the connecting plates, first chain wheels, second chain wheels, third chain wheels, first chains, second chains and connecting blocks, the longitudinal beams can move up and down, so that a vehicle is driven to move up and down; and through cooperative use of fixed columns, torsional springs, locking hooks, pins, moving rods, hydraulic telescopic rods, limiting columns, hook blocks and sliding grooves, the front end cross beam and the rear end cross beam can be locked, and therefore the safety of the lifting machine is guaranteed.

    本发明公开了一种可举升20吨的四柱式举升机,包括立柱,所述立柱的数量为四个,且通过膨胀螺丝与混凝土地面固定连接,所述立柱的顶部固定连接有侧梁,所述侧梁顶部的右侧固定连接有油缸,所述油缸的输出端固定连接有连接板。本发明通过立柱、前端横梁、纵梁、后端横梁、侧梁、上车板、油缸、控制柜、连接板、第一链轮、第二链轮、第三链轮、第一链条、第二链条和连接块的配合使用,能够使纵梁进行上下移动,从而带动车辆进行上下移动,通过固定柱、扭簧、锁紧挂钩、销轴、移动杆、液压伸缩杆、限位柱、挂钩块和滑槽的配合使用,能够对前端横梁和后端横梁进行锁止,从而保证了本设备的安全性。
