Telescopic derrick hoisting auxiliary device

Abstract

The invention discloses a telescopic derrick lifting auxiliary device, which comprises a derrick, the derrick includes support plates and connecting rods, four sets of support plates are arranged, the support plates are in a right-angle structure, and connecting rods are connected between adjacent support plates. The top of the derrick is equipped with a lifting device, and a lifting wire rope is installed on the lifting device. There are multiple sets of anti-sway devices installed on the hoisting wire rope. The anti-sway device includes a pressing block, a fixed shaft, a roller, a limit nut, A screw, a connecting rod, an adjustment piece and a second screw. There are two sets of pressure blocks. The pressure block has a C-shaped structure. The side of the pressure block is welded with a second screw, and the end of the second screw away from the pressure block is connected with an adjustment piece. , the adjustment piece is a cylindrical structure with threads inside, the adjustment piece is connected to the second screw rod through threads, and the end of the adjustment piece away from the second screw rod is welded with a connecting rod. The invention can effectively ensure that the hoisting steel wire rope will not shake under the action of the pressing block during the suspension process, thereby improving the safety of the hoisting process.

Description

technical field [0001] The invention relates to the field of petroleum machinery, in particular to a telescopic derrick lifting auxiliary device. Background technique [0002] For the existing telescopic derrick, the structure of the hoisting device often determines the spatial layout of the derrick. A good derrick hoisting device can not only optimize the structure of the telescopic derrick, but also improve the lifting capacity of the derrick when the drilling rig performs the next well operation. efficiency and reduce non-drilling operation time. [0003] The traditional lifting auxiliary device generally suspends the goods through wire ropes. During the lifting process, the wire ropes are easy to shake, causing the goods to shake. Sometimes the goods are easy to fall, and even smash the personnel on the site, which has a certain safety hazard. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to propose a telescopic derrick hoisting auxiliary d...
