Support structure for petroleum drilling

Abstract

The invention discloses a support structure for petroleum drilling. The support structure comprises a first supporting rod body, a second supporting rod body, a pressing rod head, a connecting block,a supporting frame, a motor shell, a telescopic rod, rotary discs, clamping heads, baffles, springs, a rotating rod, a fixed rod, a groove and a clamping block. The support structure has the beneficial effects that the arc-shaped groove is formed in the pressing rod head, the clamping block is mounted at the top of the groove, a drill bit for drilling and a connecting rod are connected to the clamping block, when the pressing rod head drives the connecting rod to compress the drill bit in the up-down direction, the moving range of the connecting rod is limited in the groove, thus the connecting rod can be effectively prevented from abrading the pressing rod head when moving up and down, and the situation that the connecting rod is damaged, and therefore oil production is affected is prevented; and a supporting rod for controlling the pressing rod head to move up and down is divided into two parts by the telescopic rod, the two baffles are arranged at the joint, the multiple springs aremounted between the baffles, and thus the damping effect is achieved when lever movement is conducted. The support structure has the characteristics of being resistant to abrasion, having the dampingeffect and relieving the pressure of the supporting frame.

Description

technical field [0001] The invention relates to a support structure, in particular to a support structure for oil drilling, and belongs to the application field of oil production machinery. Background technique [0002] The work of using mechanical equipment or manpower to drill the formation into holes from the ground is called drilling. Usually refers to the exploration or development of liquid and gaseous minerals such as oil and natural gas to drill boreholes and large-diameter water supply wells. Drilling is widely used in national economic construction, and the mechanical equipment for drilling is usually called drilling machine. [0003] However, existing oil drilling machines still have certain defects in use. Although the existing oil drilling machines can perforate the ground for oil production, the pressing rod head moves up and down because it drives the drilling machine to punch holes. Thereby compressing the connecting rod to carry out drilling, when the exis...

Problems solved by technology

[0003] However, existing oil drilling machines still have certain defects in use. Although the existing oil drilling machines can perforate the ground for oil production, the pressing rod head moves up and down because it drives the drilling machine to punch holes. Thereby compressing the connecting rod to carry out drilling, when the existing pressing rod head and the connecting rod move, the wearing and tearing between the pressing rod head and the connecting rod is serious, so the service life of the equipment is low, and when the motor drives the strut to carry out the lever movement , the pressure on the fulcrum is very high. During long-term use, it is easy to squeeze the support frame, making the connection part of the support frame loose, resulting in accidents
