Abstract

The invention provides a lifting device and a well repair platform, and relates to the field of well repair auxiliary equipment. The lifting device comprises a drive device, a base, a top seat and a shear fork arm. The upper end and the lower end of each of two arms of the shear fork arm are each provided with a mounting position. A first moving assembly is arranged in the base and comprises two oppositely-arranged first moving parts. The two first moving parts are correspondingly connected with the two mounting positions at the lower ends of the shear fork arm. A second moving assembly is arranged in the top seat and comprises two oppositely-arranged second moving parts. The two second moving parts are correspondingly connected with the two mounting positions at the upper ends of the shear fork arm. The drive device is connected with the two first moving parts through a transmission mechanism. The top seat is driven by the shear fork arm to stably ascend and descend up and down. The lifting device is applied to the well repair platform, and the problem that supporting is instable in the lifting process of the well repair platform is solved to a certain degree.

Description

technical field [0001] The present application relates to the field of workover auxiliary equipment, in particular to a lifting device and a workover platform. Background technique [0002] After the oil is exploited, in order to ensure the smooth use of the oil well, the platform for maintenance and maintenance of the oil well, that is, the workover platform, is often adopted; with the continuous development of oil extraction, more and more workover platforms are used. [0003] In the prior art, the workover platform used under the conditions of the oilfield environment often adopts the scissor arm structure lifting device, although it can effectively solve the problem of time-consuming and laborious adjustment and inconvenient fine-tuning caused by the inner and outer steel sockets, and the hydraulic cylinder The support is not suitable for the height of the workbench, but the roller on one side of the scissor arm structure lifting device is rolling, and the other side is ...
