Abstract

The utility model provides a drop proof safety hook for sucker rod for oil field well repairing work. The hook consists of a hook, a lower securing pin hole, a securing pin, a handle coupling rod moving slot, a connecting screw, an upper securing pin hole, a plug, a strap, a handle coupling rod and a hook body. The hook has solved the hook drop problem of a sucker rod caused by collision during the well striping process to avoid machinery and personal injury accident and guaranteed safety in production. The hook has a higher economic benefit and social benefit.

Description

A kind of sucker rod anti-run safety suspension hook

The utility model is a kind of instrument in the oil well repairing operation, particularly is a kind of sucker rod anti-run safety suspension hook.

In the oil well repairing operation process, will be one from oil well, puts forward of sucker rod, one by one following in oil well again after the completion, hang the suspension ring of sucker rod jig and put into the suspension hook that hangs sucker rod, because suspension hook is an opening, in the process of lifting or whereabouts, runs into collision and easily produce the unhook problem, cause machinery or personal injury accident, the influence safety in production.

The purpose of this utility model is developed a kind of sucker rod anti-run safety suspension hook exactly, prevents that effectively suspension ring are deviate from suspension hook when playing lower sucker rod, guarantees safe production.

Above-mentioned purpose is realized by following technical proposals:

Sucker rod anti-run safety suspension hook is made up of hole, plug, suspension ring hole, handle coupling bar and hook on hole, safety pin, handle coupling bar loose slot, connection screw, the safety pin under suspension hook, the safety pin.The suspension ring hole is on the top of hook, on the plug on safety pin above the hole, safety pin is contained on the safety pin in the hole, connection screw and handle coupling bar on the safety pin are fixed with thread connection, the handle coupling bar is up and down in handle coupling bar loose slot, and safety pin is also along with up and down in the hole on safety pin, when upwards movable, open the opening of suspension hook, the suspension ring that hang the sucker rod jig are put into and are hung sucker rod hook; When movable downwards, safety pin falls into the opening that suspension hook is sealed in hole under the safety pin, prevents that suspension ring are deviate from suspension hook when playing lower sucker rod.

After technique scheme enforcement, solve sucker rod and in the process of removing, run into the unhook problem that collision produces, avoid causing machinery or personal injury accident, ensured safety in production, improved worker's condition of labor, high economic benefit and social benefit are arranged.

Accompanying drawing 1 is a structure chart of the present utility model.

In conjunction with the accompanying drawings embodiment of the present utility model is described below:

Among the figure, the 1st, suspension hook, the 2nd, hole under the safety pin, the 3rd, safety pin, the 4th, handle coupling bar loose slot, the 5th, connect screw, the 6th, hole on the safety pin, the 7th, plug, the 8th, the suspension ring hole, the 9th, the handle coupling bar, the 10th, hook constitutes sucker rod anti-run safety suspension hook through above-mentioned each parts.Suspension ring hole 8 is on the top of hook 10, on the plug 7 on safety pin above the hole 6, safety pin 3 is contained on the safety pin in the hole 6, connection screw 5 on the safety pin 3 and handle coupling bar 9 are fixed with thread connection, when up and down, safety pin 3 is also along with up and down in the hole on safety pin 6 in handle coupling bar loose slot 4 for handle coupling bar 9, and handle coupling bar 9 is upwards movable, open the opening of suspension hook 1, the suspension ring that hang the sucker rod jig are put into and are hung sucker rod hook; Handle coupling bar 9 is movable downwards, and safety pin 3 falls into the opening that suspension hook 1 is sealed in hole 2 under the safety pin, prevents that suspension ring are deviate from suspension hook when playing lower sucker rod.
