Description

A fully automatic tubing extubation device

technical field

The invention relates to a fully automatic oil pipe extubation device, which is mainly used in deep well operation mechanical equipment.

Background technique

During downhole operations, it is sometimes necessary to send the power head driven by the oil cylinder into the downhole. Like this, the inlet and outlet oil pipes are also sent into the deep well. During construction, the extubation process is stable and continuous; it can adapt to the size of different hose diameters, and can adjust the force of the holding tube to adjust the friction force of extubation; it can realize opening and closing, and it is convenient to install the hose. Since the oil pipe is very long, it is heavy. How to operate smoothly is an urgent problem to be solved. In order to solve this problem, a kind of full-automatic tubing extubation equipment is invented.

Contents of the invention

In order to solve the problem in the prior art that it is difficult to extubate the oil pipe of the oil cylinder, the purpose of the present invention is to provide a device that can operate stably and continuously; can adapt to different hose diameters, and can adjust the strength of holding the oil pipe, thereby adjusting the friction force of extubation; It is a fully automatic tubing pulling device that can realize opening and closing and is convenient for installing tubing.

The technical scheme adopted by the present invention to solve the technical problem is: the equipment is composed of two independent frames, a tube reel is installed on one frame, and a tube extubation drive system is installed on the other frame. The hose reel is used to wind the extracted hose. An extubation drive system is used to extract the tubing from the well. In the extubation driving system, the motor is connected with four groups of worm gear transmission systems that drive the driving wheel to rotate through the worm gear reducer. Four sets of driving shafts are respectively connected with four turbines. The driving shaft and the driven shaft are installed in parallel, and a nylon roller corresponding to the diameter of the pipe is installed at one end of the driving shaft. Cooperate with the nylon rollers corresponding to the diameter of the pipe installed on one end of the driven shaft respectively, clamp the middle pipe, and pull out the pipe by friction. The nylon jacket of the roller can be easily replaced, and the center distance between the driving wheel and the driven wheel can be adjusted to facilitate the operation of pipes with different diameters.

The invention has the advantages of simple structure, stable performance, convenient maintenance, economy and durability. Reduce personnel, improve work efficiency, shorten working hours, and ensure pipe quality. The cost is saved, the benefit is increased, and the factors affecting the wellhead construction of the well construction unit are reduced.

detailed description

As shown in attached drawing 1, attached drawing 2 and attached drawing 3, the fully automatic tubing extubation equipment is mainly composed of a hose reel support 1, a reel 2, a hose 3, a guide wheel 4, a driving wheel 5, and a driven wheel 6 , installation of vertical plate 7, extubation drive mechanism support 8, driving wheel and driven wheel spacing adjustment mechanism 9, rotating shaft 10, turbine 11, worm screw 12, rotating plate 13, horizontal moving plate 14, vertical support plate 15, drive motor 16, Worm gear reducer 17, etc. are composed.

The specific embodiment is: a hose reel 2 is installed on the reel support 1, which is used to wind the extracted hose 3 and store the hose 3. The hose 3 is connected to the guide wheel 4 of the extubation device. The hose 3 is supported between the extubation driving wheel 5 and the driven wheel 6, and the driving wheel 5 and the driven wheel 6 turn in opposite directions, so that the hose can be pulled out and introduced into the deep well.

The motor is connected with the driving wheel 5 and the driven wheel 6 through a worm gear reducer to drive the driving wheel to rotate. Four groups of driving wheels 5 are connected with four turbines 11 respectively. The driving wheel 5 and the driven wheel 6 are installed in parallel, and one end of the driving wheel 5 is equipped with a nylon roller corresponding to the pipe diameter. Cooperate with the nylon rollers corresponding to the diameter of the pipeline installed at one end of the driven wheel 6 respectively, clamp the pipeline in the middle, and drive the hose to move through friction.

Driven wheel 6 is installed on the vertical plate 13, and vertical plate 13 can rotate around rotating shaft 10, can change the model of nylon roller easily.

The inboard of the two vertical support plates 15 is equipped with a horizontal moving plate 14, and the handle on the turning distance adjustment mechanism 9 can adjust the gap between the driving wheel and the driven wheel. The center distance between the driving wheel and the driven wheel is adjustable, so that it can be adjusted easily. Two rounds of support.
