a lifting platform

Abstract

The invention provides a lifting platform. The lifting platform comprises a platform body, a lifting mechanism, a locking mechanism and a plurality of retractable supporting mechanisms, wherein the lifting mechanism comprises a lifting rod, a cylinder body, an oil tank and a driving cylinder; a sealing baffle is fixed in the cylinder body; a piston is placed on the upper side of the sealing baffle; the lower end of the piston is fixed on the oil tank; an oil returning device is arranged between the sealing baffle and the oil tank; the lifting rod is placed in the cylinder body; the upper end of the lifting rod is connected with the bottom surface of the platform body; the lower end of the lifting rod is connected to the piston; the driving cylinder is a piston cylinder which can deliver hydraulic oil in the oil tank into the cylinder body so that the piston ascends; the driving cylinder is respectively connected with the oil tank and the sealing baffle of the cylinder body through a unidirectional oil delivery pipeline; the locking mechanism can lock the lifting rod so as to position the platform body and is connected to the upper end of the cylinder body in a sleeving manner; and the supporting mechanisms are correspondingly arranged at four corners of the platform body and are connected with the bottom surface of the platform body. The lifting platform can ascend and descend continuously and stop at an optional position, and is simple and convenient to operate and high in safety.

Description

technical field [0001] The invention belongs to the field of workover operations in oil fields, and in particular relates to a lifting platform, which is used for minor repair operations and other workplaces with a certain height that need to be lifted. Background technique [0002] With the continuous extension of oilfield development time, the problems of oil and water wells are becoming more and more complex. Some special equipment and tools are often used in minor repair operations to deal with these complex problems. The use of special equipment and tools often causes wellhead The increased working height brings inconvenience to minor repair operations and increases operational risks. In addition, the wellhead environment in different well sites is different, and the wellhead operating heights are uneven. In order to increase the convenience of operation and reduce the risk of operation, a lifting platform is needed. [0003] At present, there are mainly two types of pl...

Problems solved by technology

Among them, the height of the fixed platform is fixed, which cannot meet the needs of the working environment that is sometimes high and sometimes low; while the change of the working height of the plug-in platform is achieved by manually lifting the platform plane and changing the position of the plug, which requires the cooperation of multiple people and cannot be realized. Height at any position, extremely inconvenient to use
