Automatic ground pulley collimation device and method

Abstract

An automatic ground pulley collimation device comprises a balancing support, wherein a ground pulley is erected on the balancing support through a rotary shaft in a suspended mode. The device is characterized by further comprising automatic collimation levers which are symmetrically located on the two sides of the ground pulley, one end of a rotary arm is installed on the rotary shaft, the other end of the rotary arm is provided with a cable guiding hole, and the ground acting points of the ground pulley are located on the same side of the rotary shaft. The ground pulley is erected on the balancing support through the rotary shaft firstly, a bolt fixing mechanism at one end of the ground acting point of each retractable structure on the upper portion of the balancing support is detached, the cable guiding hole is detached or opened from automatic collimation lever fixing plates, and the cable guiding hole is fixed or locked after a cable is installed in cable grooves in the fixing plates. The ground pulley is prevented from moving horizontally through the ground acting points, the vertical tension of the cable is transmitted to the automatic collimation levers through the cable guiding hole in work, the plane where the cable is located is always perpendicular to the ground, and therefore the ground pulley keeps upward when pulled to get away from the ground instead of overturning.

Description

technical field

[0001] The invention relates to a detection device for oil, gas and water, which is used in the erection and operation of electric cables or optical cables in various detection environments, and is typically used in the detection of oil wells, specifically an automatic collimation device for ground pulleys. Background technique

[0002] The erection and operation of cables or optical cables in the detection environment is a common technology in the on-site detection process. The detection front-end is powered through cables or optical cables, and the front-end detection signals or data are transmitted back to the detection system host, which is typically used in oil well detection systems, etc. .

[0003] Usually, in this kind of detection system, such as the detection system of an oil well, the sky pulley and the ground pulley are required for combined operation. The sky pulley is suspended in the air above the wellhead, and the ground pulley is fixed on the...
