Pneumatic chuck remote control device

Abstract

The invention discloses a pneumatic chuck remote control device. The pneumatic chuck remote control device comprises an upper chuck, a lower chuck, an upper chuck control air cylinder, a lower chuck control air cylinder, a thrust sensor, an upper chuck alarm device, a control panel, a remote control cabinet and a connecting block. The upper chuck control air cylinder and the lower chuck control air cylinder are arranged on a side face of the upper chuck and a side face of the lower chuck respectively, protective covers are additionally arranged outside the upper chuck control air cylinder and the lower chuck control air cylinder, the thrust sensor is arranged on a top cover of the upper chuck, an alarm lamp in the alarm device is arranged into a driller room, the control panel is arranged in the remote control cabinet, and the control panel is connected with the upper chuck control air cylinder and the lower chuck control air cylinder through the connecting block and an air pressure pipeline respectively. The pneumatic chuck remote control device has the advantages that the chucks tightly clamp casing strings or release the casing strings through the remote control device, the pneumatic chuck remote control device can be operated by hand and controlled automatically and is simple in structure and convenient to operate, labor intensity of workers is relieved, and the safety coefficient of well mouth operation and work efficiency of well mouth operation are improved.

Description

technical field [0001] The invention relates to an oil field construction machine, in particular to a remote control device for upper and lower pneumatic chucks in casing casing construction in well drilling. Background technique [0002] In the 1990s, Jiangsu Xinxiang and other machinery manufacturers developed pneumatic wellhead chucks, which were used in conjunction with casing hydraulic tongs to realize the single-elevator lifting operation of "four people and one machine", which significantly reduced the labor intensity of drilling workers , the operation speed is greatly accelerated, and the safety factor of drilling construction has been improved. However, the pneumatic chuck needs to manually move the pneumatic switch handle to loosen and clamp the casing, so some problems are exposed during use: first, the damage of the tooth plate to the outer wall of the casing is serious; second, the structural design is complicated , there are many wearing parts such as chuck h...

Problems solved by technology

However, the pneumatic chuck needs to manually move the pneumatic switch handle to loosen and clamp the casing, so some problems are exposed during use: first, the damage of the tooth plate to the outer wall of the casing is serious; second, the structural design is complicated , there are many wearing parts such as chuck handles and chuck brackets; third, the auxiliary functions need to be further improved; fourth, the operator must stand near the wellhead and frequently operate the wellhead chuck to complete the lifting and lowering operation
