The invention discloses an adjustable lifting device for mechanical equipment maintenance. The device comprises a hook, a steel wire rope, a take-up and pay-off mechanism, a fixed cross beam, two supporting columns and two bearing mechanisms, wherein the two ends of the fixed cross beam are fixed to the top ends of the two supporting columns correspondingly, the take-up and pay-off mechanism is installed in the middle of the fixed cross beam, the lower end of the steel wire rope is connected with the hook through a connecting disc, the upper end of the steel wire rope receives the pay-off mechanism, the hook is hung on the top of mechanical equipment, the two bearing mechanisms support the two sides of the bottom of the mechanical equipment respectively and are in sliding connection with the two supporting columns respectively, and each bearing mechanism is connected with the connecting disc through one traction rope. The bearing mechanisms capable of synchronously ascending and descending along with the equipment are symmetrically arranged on the two sides of the mechanical equipment, the equipment is connected with the two supporting columns of the lifting device through the twobearing mechanisms, normal ascending and descending of the mechanical equipment can be guaranteed, shaking of the mechanical equipment can be prevented, therefore the equipment ascending and descending stability is improved, and the equipment maintenance efficiency is improved.

    本发明公开了一种用于机械设备维修的可调式起重装置,其包括挂钩、钢丝绳、收放线机构、固定横梁、两个支柱和两个承托机构,所述固定横梁的两端分别固定在两个支柱顶端,所述收放线机构安装在固定横梁中部,所述钢丝绳的下端通过连接盘与挂钩连接,上端接收放线机构,所述挂钩挂在机械设备的顶部,两个承托机构分别托住机械设备底部两侧并分别与两个支柱滑动连接,每个承托机构通过一根牵引绳与连接盘连接。本发明在机械设备的两侧对称设置了可随设备同步升降的承托机构,利用两个承托机构将设备与起重装置的两个支柱相连接,不仅能够保证机械设备正常升降,而且可防止其产生晃动,从而增加了设备升降稳定性,提高了设备维修效率。
