Novel iron driller support arm and iron driller comprising the support arm

Abstract

The invention relates to the field of petroleum drilling machinery, in particular to a novel iron driller support arm, which includes: a joint frame, which is a steel structure, located in the middle of the support arm; two sets of connecting rods, which are respectively hinged on the left and right sides of the joint frame On the right side, the other ends of the two sets of connecting rods are respectively hinged with the tong foundation and tong head assembly of the iron driller. The connecting rods in a single group include at least the upper and lower connecting rods, and the upper and lower connecting rods in a single group are at least Including 1 pair of connecting rods, joint frame, single set of connecting rods, tong base, and pliers head assembly respectively form a number of parallelogram linkages in a vertical plane parallel to each other; the driving device is installed on the joint frame are respectively hinged with the middle parts of the two groups of connecting rods, and can drive the lower ends of the two groups of connecting rods to approach or move away from each other; the purpose of the present invention is to provide a support arm with a large radius during operation, a compact structure and a small area of ​​the drill floor when stored, The invention also discloses an iron driller comprising the support arm.

Description

technical field [0001] The invention relates to the field of petroleum drilling machinery, in particular to a novel iron driller support arm and an iron driller comprising the support arm. Background technique [0002] In the oil drilling industry, connecting single rods and tripping out the drill is a repetitive and heavy work for drilling workers. At present, oil drilling rigs are often equipped with drill pipe power tongs (referred to as tongs) to remove threaded joints of drill pipe strings. This requires frequent movement of equipment such as tongs from wellheads to rat holes, storage bits, etc. However, these devices are generally heavy in weight, and the space around the wellhead is very crowded, and accidents to personnel and equipment are often caused when these devices are moved. [0003] One method that has been used in the past is to move equipment such as tongs from the storage location to the wellhead with a block mounted on the rig floor rails. The disadvan...

Problems solved by technology

[0009]Existing iron drillers generally have the following problems: the angle of make-up and breakout is small, and it needs to be repeated many times to complete make-up and breakout; The damage is large; the torque of the turnbuckle is small; the neutrality of the drilling tool is not good; the working range is often proportional to the external size, and the transportation is inconvenient
