Abstract
The invention discloses a safety pin capable of preventing an elevator from falling off. The safety pin is characterized in that a hinge base is welded onto the lower part of a handle of an elevator pin rod; a pin hole is formed in the hinge base; a pin hole is also formed in the front end of a handle of a lock hook; a pin bolt penetrates through the two pin holes to connect the two holes together; an upper support base and a lower support base are positioned between and welded onto the handle of the elevator pin rod and the handle of the lock hook respectively; a reset spring is added between the lower support base and the upper support base 7; a safety rope ring is welded at the front end of the handle of the elevator pin rod. When the tubular column is to be removed, the handles are held by hands, the handle of the lock hook is nipped, the reset spring is compressed, the lock hook is opened, the elevator pin rod is inserted in an eyehole of an elevator lug, the handle of the lock hook is released, and the lock hook and the elevator pin rod are closed under the function of the reset spring; when the elevator turns over in an accident, the elevator pin rod can be prevented from falling off the eyehole of the elevator lug due to the function of the lock hook, and the elevator can be prevented from falling off the elevator ring and injuring people and equipment.
Description
Technical field
Type of the present invention relates in the eyelet that injects when the petroleum drilling well workover plays lower tubular column on the elevator ear, prevents other secondary accident that elevator comes off from suspension ring and causes.
Background technology
The petroleum drilling well workover make a trip the hollow tourist bus can touch on rope in being suspended to the derrick space and some object in the upper and lower process in derrick space because of reasons such as swings or hang over suspension ring when braking suddenly in elevator just might overturn, this moment, on-the-spot straight-bar elevator pin commonly used will drop out from the hole of elevator hanger, the hanger of elevator both sides is thrown off from suspension ring one side, cause elevator to be pounded to rig floor from falling in the air, injure personnel or equipment etc., have great potential safety hazard.
Summary of the invention
Have potential safety hazard for the present straight-bar elevator pin used in scene, the purpose of type of the present invention has aimed to provide a kind of safety pin that prevents that elevator from coming off from suspension ring.The safety pin is taked self-lock mechanism, guarantees elevator pin in the situation that the elevator upset can not come off yet, and guarantees that elevator is not shed to drilling floor surface and hurts sb.'s feelings from suspension ring.
The purpose of type of the present invention is completed like this:
The anti-elevator safety pin that comes off mainly is comprised of elevator pin rod, mousing-hook, pin, hinge seat, lower support seat, back-moving spring, upper support seat, safe becket bridle.Hinge seat is welded under the handle of elevator pin rod, have pin-and-hole on hinge seat, the handle front end of mousing-hook also has pin-and-hole, piercing into pin in two pin-and-holes links together, the handle among of the handle of elevator pin rod and mousing-hook is welded with upper support seat and lower support seat, be added with back-moving spring between lower support seat and upper support seat, the handle front end of elevator pin rod is welded with safe becket bridle.
The advantage of type of the present invention and the beneficial effect of generation are:
1, type of the present invention adopt conventional part assembling, simple in structure, can easily process according to various elevator sizes, cost is low, have advantages of generally and use.
2, because adopting self-lock mechanism, guarantee elevator pin in the situation that the elevator upset can not come off, guarantee that elevator is not shed to drilling floor surface and hurts sb.'s feelings from suspension ring.
Description of drawings
Fig. 1 is type schematic diagram of the present invention.
The specific embodiment
as shown in Figure 1, a kind of anti-elevator comes off safety pin mainly by elevator pin rod 1, mousing-hook 2, pin 3, hinge seat 4, lower support seat 5, back-moving spring 6, upper support seat 7, safe becket bridle 8 forms, hinge seat 4 is welded under the handle of elevator pin rod 1, have pin-and-hole on hinge seat 4, the handle front end of mousing-hook 2 also has pin-and-hole, piercing into pin 3 in two pin-and-holes links together, the handle among of the handle of elevator pin rod 1 and mousing-hook 2 is welded with upper support seat 7 and lower support seat 5, be added with back-moving spring 6 between lower support seat 5 and upper support seat 7, the handle front end of elevator pin rod 1 is welded with safe becket bridle 8.
Hold handle when playing lower tubular column, when pinching mousing-hook handle 2, back-moving spring 6 is compressed, mousing-hook 2 is opened, unclamping the handle of mousing-hook 2 in the eyelet of elevator pin rod 1 reeve elevator ear, mousing-hook 2 and elevator pin rod 1 place's closure under the effect of back-moving spring 6, when elevator overturns for some reason, because the effect of mousing-hook 2 is arranged, elevator pin rod 1 can not come off from the jack of elevator ear, does not pound people and the equipment of injuring under the assurance elevator can not come off from suspension ring.Fastened the elevator pin safety rope in becket bridle 8 and tied up on suspension ring, prevented from that it from coming off to hurt sb.'s feelings.Hold handle when getting elevator pin rod 1, when pinching mousing-hook handle 2, back-moving spring 6 is compressed, and mousing-hook 2 is opened, and elevator pin rod 1 is extracted out from the eyelet of elevator ear both completed once-through operation.
