The invention discloses a special lifting appliance for lifting a hydrogenation reactor. The special lifting appliance comprises a base, a first lifting ring, a second lifting ring, a controller, an external power line, a right clamping and positioning mechanism, a left clamping and positioning mechanism, a bidirectional adjusting device and an auxiliary guiding and conveying mechanism. Accordingto the special lifting appliance, the right clamping and positioning mechanism and the left clamping and positioning mechanism are arranged, a first clamping piece and a second clamping piece are synchronously and rapidly opened and closed under the control of a synchronous rotating mechanism, the hydrogenation reactor can be rapidly clamped and positioned from the two ends, and therefore the hydrogenation reactor can be lifted more stably, and the lifting safety is improved; and the bidirectional adjusting device is arranged, under the driving of an electric push rod, pushing is carried out in cooperation with a synchronous pushing mechanism, a left moving plate and a right moving plate move relatively, the distance between the right clamping and positioning mechanism and the left clamping and positioning mechanism can be adjusted conveniently, the special lifting appliance can better adapt to hydrogenation reactors of different sizes, and the working efficiency is improved.

    本发明公开了一种用于加氢反应器起吊专用吊具,包括底座、第一吊环、第二吊环、控制器、外接电源线、右夹持定位机构、左夹持定位机构、双向调整装置和辅助导送机构。本发明通过设置了右夹持定位机构和左夹持定位机构,由同步转动机构控制下,使第一夹持件和第二夹持件进行同步快速开合,可从两端对加氢反应器进行快速的夹持定位,从而使加氢反应器起吊时更为稳定,提高起吊的安全性,并且设置了双向调整装置,在电动推杆驱动下,并配合同步推送机构进行推送,使左移动板和右移动板相对进行移动,使右夹持定位机构和左夹持定位机构相互间距便于调整,更好的适应不同尺寸的加氢反应器,提高工作效率。
