Embodiment Construction
[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0036] The naming of the left and right directions in the following text is only based on the drawings, and the actual setting position can be deduced by analogy.
[0037] The structure of the automatic vertical tube lifting device of the present invention is to include four parts: a connection mechanism connected in order from top to bottom, an upper bracket, a lower bracket and a tube clamping mechanism,
[0038] refer to figure 1 , the structure of the connection mechanism is to include a hanging plate 1, the hanging plate 1 is used to flexibly connect upwards to other equipment in the string processing system, the hanging plate 1 is fixedly connected to the connecting frame 2 downwards, and the lifting lug at the center of the lower end surface of the connecting frame 2 The connecting pin 4 is hooked with the boom 16 in the upper bracket...

The invention discloses an automatic vertical tube bank lifting device. The automatic vertical tube bank lifting device comprises four portions of a connection mechanism, an upper support, a lower support and a tube bank clamping mechanism, which are sequentially connected from the top down, wherein the upper support structurally comprises a screw thread compensation mechanism and a revolution adjustment mechanism, and the lower support structurally comprises a rigid main body arm frame and a connection rod drive mechanism. According to the automatic vertical tube bank lifting device, the screw thread compensation mechanism is used to buffer hard contact disadvantages which occur during the pipe pillar connection process, the revolution adjustment mechanism drives the tube bank clamping mechanism to perform reverse trace revolution, and controls a suitable clamping direction of pipe pillars, and the connection rod drive mechanism adjusts work postures of a clamping device in real time, controls opening and closing action of clamping through a flipping chuck fixed on a clamping support seat, and cooperates in coherently completing pipe connection and grabbing action. The automatic vertical tube bank lifting device significantly improves operation efficiency of a pipe pillar processing system, and obviously reduces labor intensity of workers.
Description
technical field [0001] The invention belongs to the technical field of petroleum machinery and is used for a vertical pipe processing device in an automatic pipe string processing system for oil drilling and workover operations, and relates to an automatic vertical pipe row lifting device. Background technique [0002] The disadvantages of the traditional operation process of tripping, connecting single pipes and guiding risers are: long operation period, high labor intensity, high risk of repeatability of pipe string operations, and the cooperation of multiple people is required to complete. Especially in offshore drilling operations, the working environment is harsh and the safety status is prominent. How to avoid direct contact between workers and pipe strings, reduce operational safety risks, accelerate tripping speed, shorten drilling cycle, and reduce offshore drilling costs is particularly urgent and important.
