Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a small oil pipe block with a deceleration function, one of the purposes is to have one end of the oil pipe that can be stably reinforced inside the small block, and to solve the problem that one end of the oil pipe is not in the small block and is sliding. In the process, there is the problem that the oil pipe is easy to tilt and scratch the oil pipe; another purpose is to solve the problem that the oil pipe trolley cannot stop at a stable speed, so as to avoid the problem of rushing out of the oil pipe or causing injury to the staff, so as to achieve Allow the trolley to slow down in time and stop at a slow speed, preventing the tubing trolley from causing safety hazards due to speed

Abstract

The invention discloses a small tubing block with a deceleration function, which relates to the technical field of auxiliary equipment for petroleum downhole operations, and includes a block frame and a pulley. The bottoms of both ends of the casing are fixedly connected with first magnetic pole pieces, and the rolling balls The bottom is fixedly connected with a second magnetic pole piece, the end of the sliding rod away from the rotating shaft is fixedly connected with a friction plate, and the inside of the sliding rod is slidably connected with a gravity ball. The present invention adopts the combination of the pressing block and the clip. When the pressing block is pressed down, the block is pushed out according to the principle of same-sex repulsion to push the clip out. The symmetrical clips on both sides can firmly clamp the oil pipe in the middle, preventing the oil pipe In the process of sliding, there is a danger of tilting and toppling. The combination of the upper sliding rod and the lower rod is set. When the magnet block is separated from the surface of the oil pipe, the lower rod rotates downward and presses against the inner wall of the oil pipe. The sliding block and the soft rod extend as the lower rod falls The friction plate accelerates the deceleration process of the trolley, prevents the small trolley from sliding down too fast, and avoids accidental injury to the operator.

Description

technical field [0001] The invention relates to a small oil pipe pulley, and relates to the technical field of auxiliary equipment for oil well operations, in particular to a small oil pipe pulley with a deceleration function. Background technique [0002] Oil downhole operations are mainly engaged in overhaul, oil testing, maintenance, and measure operations of oil wells in oilfields. Hundreds of oil pipes are pulled from the wellbore every day. In the process of oil downhole operations, the construction process of downhole operations takes the longest time. In order to improve the operation efficiency and protect the connection thread of the pipe string, the staff generally fixes two parallel pipe strings at the well site. The use of the tubing pulley can avoid the wear of the tubing thread, especially when the pump is down. If the tubing pulley is not used, the tubing thread will carry sediment and fall into the pump, which will lead to problems such as construction quali...
