Support structure for oil drilling

Abstract

The invention discloses a support structure for oil drilling. The support structure comprises a first fulcrum bar, a second fulcrum bar, a pressure bar head, a connection block, a support frame, a motor shell, a telescopic rod, a swivel plate, a clamping head, baffles, springs, a rotating rod, a fixing rod, a groove and a clamp block. The support structure for oil drilling has the beneficial effect that the arc groove is formed in the pressure bar head; the clamp block is installed at the top of the groove; a drill bit for drilling and a connecting rod are connected to the clamp block; the moving range of the connecting rod is restricted to the inner part of the groove when the pressure bar head drives the connecting rod to press the drill bit vertically, so that the wear of the pressure bar head can be effectively prevented when the connecting rod moves up and down and damage, affecting oil recovery, of the connecting rod is prevented; the fulcrum bars which control the pressure bar head moving up and down are divided into two parts by the telescopic rod; and two baffles are arranged at the interface, a number of springs are installed between the baffles, so that the effect of shock absorption is achieved when the lever movement is made. The support structure for oil drilling has the characteristics of abrasion prevention, shock absorption and support frame pressure relieving.

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
