Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] Such as Figure 1 to Figure 3 The derrick of a trailer drilling and repairing rig is shown as a two-section four-section, front-opening package derrick, which includes a lower bottom section 6, an upper bottom section 4, a lower top section 3, an upper top section 1, and a lower bottom section. The top of the section 6 and the bottom of the upper bottom section 4 are connected to each other through the bottom section connecting device 5 to form the bottom section, and the top of the lower top section 3 and the bottom of the upper top section 4 are connected to each other through the top section connecting device 2 to form the top section, The top section is set inside the bottom section, and the bottom of the top section is connected with the jacking hydraulic cylinder. The expansion and contraction of the jacking hydraulic cylinder can drive the top s...

Abstract

This invention discloses a trailer drilling and repairing machine derrick. The derrick is a two-segment four-section front-opening sleeving derrick, wherein the top end of a lower bottom section and the bottom end of an upper bottom section are connected with each other through a bottom section connecting device to form a bottom section, the top end of a lower top section and the bottom end of anupper top section are connected with each other through a top section connecting device to form a top section, the bottom of the top section is connected with a jacking hydraulic cylinder, and the expansion and contraction of the jacking hydraulic cylinder can drive the top section to slide up and down along the inner side of the bottom section, and when the top section extends out of the bottom section to reach the highest position, and the overlap areas of the lower part of the lower top section and the upper part of the upper bottom section cling to each other. The trailer drilling and repairing machine derrick ensures the stable connection between derrick segments and improves the stability of the derrick. During movement, the derrick could be folded in different ways according to actual needs to be suitable for long-time stand and improve working efficiency while simplifying the assembly and dismantling of the derrick and reducing labor work to realize rapid movement.

Description

technical field [0001] The invention relates to the technical field of oil drilling and production equipment, in particular to a towed drilling and repairing rig derrick capable of smooth and fast lifting, fast installation and transportation. Background technique [0002] The derrick of the towed drilling and repairing rig is one of the most important components in its operation. The design of the derrick requires sufficient strength and height to meet the requirements of operation, tripping, vertical root discharge and sufficient operating space. [0003] According to the number of derrick expansion joints, the trailer derrick can be divided into single-section derrick, double-section derrick and three-section derrick. Due to limitations in manufacturing and transportation, the length of a single-section derrick cannot be made too long. Theoretically, the more the number of sections, the higher the vertical height of the derrick. The higher the derrick, the higher the oper...
