An automatic operating device for drilling pipes up and down the drill floor

Abstract

The invention provides a device for automatically moving drill pipes onto and off a drill floor. According to the technical scheme, the device comprises an open ramp, an open catwalk, a slideway vehicle slidably matched with the catwalk, an open mouse hole and a slideway vehicle slidable matched with the mouse hole. Pushing stopping, turning and grasping mechanisms are respectively disposed at the mouse hole in the lower end of the ramp and connection of the ramp and the catwalk. The catwalk is provided with an opening, the mouse hole is provided with an opening from the middle portion to the bottom, so that pipe penetration and turning are facilitated. Drill pipe receiving and discharging can be performed at the upper end of the mouse hole, an air winch for moving the drill pipes upwards and downwards is not needed, wellhead operators are reduced, and potential safety hazards are reduced. The device is reasonable in structural design, simple and reliable to operate, manpower saving, efficient and safe, and suitable for drilling machines with the drill floors higher than 9.5m.

Description

technical field [0001] The invention relates to the field of drilling engineering machinery, in particular to an automatic operation device for drilling pipes up and down the drill floor. Background technique [0002] Drill pipe loading and unloading on and off the drill floor is an important operation for the drilling team. It is necessary to put all the drill pipes on the pipe rack and the drill floor on and down to the drill pipe rack on the drill floor and below the drill floor. 200-400, more than 1,000, the workload is heavy. In the past, the drilling team usually used the pneumatic winch on the drill floor and the pneumatic winch on the catwalk to pull one end of the drill pipe, pull the wire rope on the bottom, and feed the wire rope on the top. The two pneumatic winches run synchronously to lift the drill pipe from the drill floor to the low-level catwalk. [0003] For example, the patent No. CN102230364A discloses a "drill pipe up and down drill floor automatic ope...

Problems solved by technology

[0008] However, this kind of operation requires that the upper and lower two people who operate the pneumatic winch must cooperate well and synchronize as much as possible. The requirements for operators are high, the operation process is complicated, and the production efficiency is low. Occasionally, accidents occur due to improper cooperation. and staff, there are certain security risks
