Problems solved by technology

[0002] The sucker rod is the power transmission component of the oil pump in the pumping well. Several sucker rods are connected to each other from the ground to the downhole. During the working process of the sucker rods, the slender sucker rods are formed by screwing each other Bending and twisting will inevitably occur in the components, which will form the rotational torque between the sucker rods, which will easily cause the screwing of the sucker rods that are connected to each other to loosen and cause mutual tripping. In addition, the existing oil pumping The connection of the rod joint is inconvenient and the operation is cumbersome, so it is necessary to develop a locking and fastening sucker rod detachment device with stable connection and convenient operation, and it is necessary to ensure the stability of the structure

Abstract

The invention discloses a locking and fastening type sucker rod anti-falling device. The locking and fastening type sucker rod anti-falling device comprises locking and fastening mechanisms. According to the anti-falling device, the locking and fastening mechanisms are additionally arranged, clamping plates are installed at the upper ends of penetrating cross rods, the clamping plates are clamped to clamping channels in a sliding mode, threaded columns are installed at the upper ends of the clamping plates and located in driving channels, floating nuts are rotationally connected to the threaded columns in a threaded mode, and the peripheries of the lower ends of the floating nuts are connected with abutting fastening rings, such that the abutting fastening rings are connected to the lower sides of the driving channels in an abutting or separating mode through rotation of the floating nuts, radial limiting of movable longitudinal rods is achieved, and locking of a lower connector is achieved.

Description

technical field [0001] The invention relates to a locking and fastening type sucker rod detachment preventer. Background technique [0002] The sucker rod is the power transmission component of the oil pump in the pumping well. Several sucker rods are connected to each other from the ground to the downhole. During the working process of the sucker rods, the slender sucker rods are formed by screwing each other Bending and twisting will inevitably occur in the components, which will form the rotational torque between the sucker rods, which will easily cause the screwing of the sucker rods that are connected to each other to loosen and cause mutual tripping. In addition, the existing oil pumping The connection of the rod joint is inconvenient and the operation is cumbersome. Therefore, it is necessary to develop a locking and fastening sucker rod detachment preventer with stable connection and convenient operation, and it is necessary to ensure the stability of the structure. ...
