The lifting equipment comprises an oil storage tank, an oil cylinder and an oil pump, an oil suction pipeline is arranged between the input end of the oil pump and the oil storage tank, a first one-way valve is arranged on the oil suction pipeline, an oil discharge pipeline is arranged between the output end of the oil pump and the oil cylinder, and a second one-way valve is arranged on the oil discharge pipeline. A backflow pipeline is arranged between the oil cylinder and the oil storage tank, a stop valve is arranged on the backflow pipeline, an end cover is fixedly installed at the upper end of the oil storage tank, a piston plate is installed in the oil storage tank in a sliding and sealing mode, a lifting air bag is arranged between the piston plate and the end cover, and the oil cylinder comprises a piston rod, a piston body and a cylinder body. Two ends of the pull rope are fixedly connected with the piston plate and the piston body respectively. The lifting air bag and the pulley structure are arranged between the oil cylinder and the oil storage tank, so that the loading capacity of the piston rod of the hydraulic jack is improved, and the piston body is not prone to oil leakage and damage.

    本发明公开了一种汽车维修用升降设备,包括储油罐、油缸和油泵,油泵的输入端与储油罐之间设有吸油管道,吸油管道上设有第一单向阀,油泵的输出端与油缸之间设有排油管道,排油管道上设有第二单向阀,油缸与储油罐之间设有回流管道,回流管道上设有截止阀,储油罐的上端固定安装有端盖,储油罐内滑动密封安装有活塞板,活塞板与端盖之间设有升降气囊,油缸包括活塞杆、活塞体和缸体,端盖上转动安装有定滑轮,定滑轮上安装有拉绳,拉绳两端分别固定连接活塞板和活塞体。本发明通过在油缸和储油罐之间设置升降气囊和滑轮结构,提高了液压千斤顶的活塞杆的载荷能力,使得活塞体处不容易漏油和损坏。
