Pull type base device

Abstract

The invention discloses a pull-type base device, and aims to solve the problem that the height of a pull-type base is inconvenient to adjust, so that the pull-type base is inconvenient to move and transport in the prior art. A base lower seat; each stand column is provided with a first connecting end hinged to the upper base and a second connecting end hinged to the lower base; the first limiting assembly and the second limiting assembly are configured to limit rotation of the hinged position of the second connecting end. When the stand column rotates to a first state around the hinged position of the second connecting end, the stand column is connected with the lower base through the first limiting assembly. When the stand column rotates around the hinged position of the second connecting end to a second state, the stand column and / or the upper base are / is connected with the lower base through a second limiting assembly. The pull type base can be switched between a working state and a moving state, so that the pull type base is low in height space requirement during moving, and moving is convenient.

Description

technical field [0001] The invention relates to the technical field of oil and natural gas drilling equipment, in particular to a trailer-type base device capable of quickly moving the entire base of a drilling rig. Background technique [0002] The trailer-type base is suitable for quickly moving the base of the drilling rig to a new wellhead position between well sites or within the well site, which can greatly save the moving time and has an irreplaceable position by other mobile devices. [0003] The trailer-type base in the related art includes an upper base and a lower base. The upper base and the lower base are connected by several reinforcing ribs. The lower base is mainly used to connect with the installation base. The base is also provided with tires for easy transportation. , The upper seat of the base is mainly used to connect with other equipment such as the derrick. The height of the trailer-type base cannot be adjusted, and a high transportation space is requi...
