Automatic arm retraction type putting and fishing device

Abstract

The invention relates to an automatic arm retraction type putting and fishing device. A putting and fishing claw (5) is composed of an upper putting and fishing claw (52), a lower putting and fishing claw (53), a pup joint (54), a pressure spring (55) and a pressure feed head or a fishing head (56). The automatic arm retraction type putting and fishing device further comprises a sliding block (57), a push-pull rod (58) and a tension-pressure dual-purpose spring (59). The sliding block (57) is installed on a sliding track (22) of an upper body 2 in a sliding mode, a sliding block stop mechanism (7) is arranged on the sliding block (57), an upper locking groove (23) and a lower locking groove (24) are formed in the upper end and the lower end of the sliding track (22) respectively, one end of the push-pull rod (58) is hinged to the pup joint (54), the other end of the push-pull rod (58) is hinged to the sliding block (57), one end of the tension-pressure dual-purpose spring (59) is connected to the middle of the upper putting and fishing claw (52), and the other end of the tension-pressure dual-purpose spring (59) is connected with the sliding block (57). The putting and fishing claw of the automatic arm retraction type putting and fishing device is spread under a well and can be automatically retracted into the upper body after the putting and fishing process is finished, the putting and fishing claw can continue to be put into the position below a water distributor, and the overall working progress of an oil field can be easily accelerated.

Description

technical field [0001] The invention relates to petroleum tools, in particular to an eccentric water distributor blocker thrower which can automatically retract the thrower claw. Background technique [0002] The eccentric water distributor thrower is a tool used to throw and fish the plug in the eccentric hole of the eccentric water distributor in the well. It can be used for throwing and fishing the plug, and can also be used to replace the water nozzle. It is very convenient to use. However, the throwing claws of the existing eccentric water distributors cannot be automatically received in the upper body after the throwing and fishing process is completed when they are opened underground. , so it cannot cooperate with other tools to carry out the next operation, which is not conducive to improving the overall operation progress of the oil field. Contents of the invention [0003] The purpose of the present invention is to provide a throwing claw that can be automatical...
