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

Abstract

The invention relates to the field of petroleum drilling equipment, in particular to a novel spinner. The novel spinner comprises two spinning roller assemblies, a symmetrical clamping system and a suspension system, wherein spinning rollers are arranged on the spinning roller assemblies, two clamping arms which are bent inwards and can open and close are symmetrically arranged on the symmetrical clamping system, the spinning roller assemblies are hinged to the free ends of the clamping arms respectively in the direction of closing of the clamping arms, and the spinning roller assemblies are further provided with second connecting positions used for being connected with the symmetrical clamping system. The symmetrical clamping system is designed according to the translational motion characteristic of edges of a parallelogram and the symmetry characteristic of slidable symmetrical connecting rods, and thus the layout that the four spinning rollers which can keep the symmetrical clamping state oppositely clamp a pipe is formed. The symmetrical clamping system is flexibly connected to the suspension system. The novel spinner has the advantages that the novel spinner large in spinning torque, high in spinning speed, large in application range of pipe diameters and small in size, and the state that the four spinning rollers in the symmetrical clamping state oppositely clamp the pipe can be kept.

Description

technical field [0001] The invention relates to the field of oil drilling equipment, in particular to a novel 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...
