The invention discloses an electric power overhaul lifting device. According to the technical scheme, the electric power overhaul lifting device comprises a push-up mechanism and a pull-up mechanism;the push-up mechanism comprises a lifting support, the lifting support comprises cross-connected connecting rods, the top of the lifting support is connected with a lifting table, and the bottom of the lifting support is connected with a base; and the pull-up mechanism comprises telescopic rods distributed on the two sides of the lifting table, fixed pulleys are arranged at the tops of the telescopic rods, the pull-up mechanism further comprises a pay-off wheel shaft, and a cable of the pay-off wheel shaft bypasses fixed pulleys at the tops of the telescopic rods to be connected with the end of the lifting table. Through cooperation of the pull-up mechanism and the push-up mechanism, the problems that when a heavy object is lifted, a single push-up mechanism bears too large loads, and consequently the device is unstable and shakes are solved.
本发明为一种电力检修升降装置。其技术方案为:包括推升机构和上拉机构;推升机构包括升降支架,升降支架包括交叉连接的连杆,升降支架顶部连接升降台,升降支架底部连接底座;上拉机构包括分布在升降台两侧的伸缩杆,伸缩杆顶部设置定滑轮,上拉机构还包括放线轮轴,放线轮轴的线缆绕过伸缩杆的顶部的定滑轮连接所述升降台的端部。通过上拉机构和推升机构合作,减小在升降重物时,单一推升机构承受载荷过大,造成装置不稳定,发生晃动的问题。
