Problems solved by technology

The biggest feature of the scissors-type two-point four-wheel spinner is that it overcomes the problem of the large lateral length of the above-mentioned clip-type spinner and the need for guide rail guidance (according to the different positions of the oil cylinders, there are also problems of hydraulic cylinder tension and large cylinder diameter. ), but when clamping different drill pipes, the clamping center will change, and the pressing force of the four rotary wheels on the drill pipe is different, and the driving force of the four rotary wheels on the drill pipe is different
The arrangement of the three-rotor wheel overcomes the above problems, but it is bulky and complex in structure

Embodiment 1

[0043] Such as figure 1 , 3, 11, a spinner, which includes:

[0044] The number of rotating wheel assembly 1 is two. A single rotating wheel assembly 1 is provided with two rotating wheels 16 that are parallel to each other and can rotate around its central axis. The two rotating wheel assemblies 1 can cooperate with each other to pass through. The rotating wheel 16 clamps a tube parallel to the central axis of the rotating wheel 16. The rotating wheel 16 is cylindrical, and its circumferential side is equidistantly spaced around the central axis with two identical intermediate grooves 41, forming three annular convex surfaces 42, when the tube is clamped, the raised surface 42 is in contact with the tube, and an anti-slip groove is provided on the raised surface 42;

[0045] Symmetrical clamping system 2, on which two inwardly bent clamping arms 21 are symmetrically arranged, and the clamping arms 21 are opened / closed by a separate driving device. The two rotary wheel assemblies ...

Abstract

The present invention relates to the field of oil drilling equipment, in particular to a spinner, which includes: two rotary wheel assemblies, on which rotary wheels are arranged; a symmetrical clamping system, on which two inwardly curved can Open / close the clamping arm, the rotary wheel assembly is respectively hinged on the free end of the clamping arm towards the closing direction of the clamping arm, the rotary wheel assembly is also provided with a second connection with the symmetrical clamping system, the symmetrical clamping The holding system is designed according to the translational characteristics of the parallelogram sides and the symmetrical characteristics of the slidable symmetrical connecting rod, so as to form a four-rotor wheel pair clamping pipe layout that can maintain a symmetrical clamping posture; the suspension system, the symmetrical clamping system is flexible Connected to the suspension system; the purpose of the present invention is to provide a four-rotor wheel clamping pipe that has a large twist torque, a high spin speed, a wide range of applicable pipe diameters, a small volume, and can maintain a symmetrical clamping posture. State of the spinner.

Description

technical field [0001] The invention relates to the field of oil drilling equipment, in particular to a spinner. Background technique [0002] Drilling is one of the most important means of oil and gas development, and the rotary drilling method is generally used at present. When drilling, with the deepening of the wellbore or the wear of the drill bit during the drilling process, the drill bit needs to be replaced. Open), oil drilling industry is called single root and tripping operation. [0003] Drill pipe needs a lot of torque and a very low speed when it is tightened or unfastened, but it needs a small torque and a high speed when it is twisted. At present, hydraulic-pneumatic hybrid tongs are often used on conventional drilling rigs to perform make-up and break-out operations of drill pipes. The biggest disadvantages are that the scope of applicable pipe diameters is small and the volume is large and the level of automation is low; B is often used when handling large...
