Abstract
The utility model discloses a novel safe elevator pin. The novel safe elevator pin is characterized in that an upper pin rod is in screwed connection with a lower pin rod, an upper ring of a spring anchor is arranged at the screwed connection position in a sleeved mode and limited at the screwed connection position and cannot move at will, and a lower ring is arranged on the lower pin rod in a sleeved mode and can move up and down; a handle of the upper pin rod is held by hand, the lower pin rod is inserted into a pin hole of an elevator lug, force is slightly applied, a spring piece of the spring anchor is squeezed and compressed, the lower ring is pushed by the spring piece to move downwards, the anchor is compressed into the pin hole of the elevator lug, after the spring anchor leaves the pin hole of the elevator lug, the lower ring moves upwards under the action of elastic force, the spring piece is arched once again, and the elevator pin is anchored in the lifting lug of an elevator. When the elevator turns over due to an accident, the pin rod of the elevator cannot be disengaged from the pin hole of the elevator lug because of the anchoring effect of the spring anchor. A safety rope ring is welded to the front end of the handle of the upper pin rod, and a safety rope is tied to the rope ring, tied to a hanging ring and prevented from disengaging and hurting people. When the elevator pin is taken, the handle of the upper pin rod is held by hand, force is exerted upwards, and the elevator pin can be taken out by using the method.
Description
Technical field
The utility model relates to when the petroleum drilling well workover plays lower tubular column in the pin-and-hole injected on the elevator ear, prevents from that elevator from coming off from suspension ring to cause other secondary accident to occur.
Background technology
Up in the derrick space at the petroleum drilling well workover hollow tourist bus that makes a trip, can touch on the rope that is suspended in the derrick space and some object because of reasons such as swings in decentralization process or hang over the just likely upset of elevator in suspension ring while braking suddenly, now 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, 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
The potential safety hazard existed for the current straight-bar elevator pin used in scene, the purpose of this utility model has aimed to provide a kind of new type of safe elevator pin, prevent that elevator from coming off from suspension ring, but this new type of safe elevator pin adopt spring anchor elastic shrinkage and again the principle of spreading grappling elevator pin is fixed in the elevator earrings firmly, guarantee elevator pin in the situation that the elevator upset can not come off yet, guarantee that elevator is not shed to drilling floor surface and hurts sb.'s feelings from suspension ring.
The purpose of this utility model completes like this:
A kind of new type of safe elevator pin is mainly by lower pin rod, the spring anchor, upper pin rod, safe becket bridle forms, the bottom of upper pin rod has screw, the top car of lower pin rod has and the screw of the upper pin rod screw mandrel with button-type, lower pin rod is connected with the screw on upper pin rod through the spring anchor, the pressed on ring internal diameter of spring anchor is slightly larger than the screw mandrel diameter, be less than the body diameter of pin rod and lower pin rod and be enclosed within on the screw mandrel of lower pin rod, the shoulder place that the pressed on ring of spring anchor is limited between pin rod and lower pin rod can not move up and down arbitrarily, the lower ring internal diameter that the spring cat is determined device is slightly larger than the external diameter of pin rod, be enclosed within on lower pin rod and can move up and down, the handle corner of upper pin rod is welded with safe becket bridle.
The beneficial effect of advantage of the present utility model and generation is:
1, the utility model adopt the assembling of conventional part, simple to operate, can easily process according to various elevator sizes, cost is low, have advantages of generally and use.
2, because the employing arcuate bombing leaf is compressible and the principle of energy spreading grappling, guarantee elevator pin in the situation that the elevator upset can not come off yet, guarantee that elevator is not shed to drilling floor surface secondary accident occurs from suspension ring.
The accompanying drawing explanation
Fig. 1 is the utility model sectional drawing.
Fig. 2 is the utility model spring anchor.
The specific embodiment
As shown in Figure 1, a kind of new type of safe elevator pin is mainly by lower pin rod 1, spring anchor 2, upper pin rod 3, safe becket bridle 4 forms, the bottom of upper pin rod 3 has screw, the top car of lower pin rod 1 has and the screw of upper pin rod 3 screw mandrel with button-type, lower pin rod 1 is connected with the screw on upper pin rod 3 through spring anchor 2, the pressed on ring internal diameter of spring anchor 2 is slightly larger than the screw mandrel diameter, be less than the body diameter of pin rod 3 and lower pin rod 1 and be enclosed within on the screw mandrel of lower pin rod 1, the shoulder place that the pressed on ring of spring anchor 2 is limited in 1 of pin rod 3 and lower pin rod can not move up and down arbitrarily, the lower ring internal diameter that the spring cat is determined device 2 is slightly larger than the external diameter of pin rod, be enclosed within on lower pin rod 1 and can move up and down, the handle corner of upper pin rod 3 is welded with safe becket bridle 4.
Hold the handle of pin rod 3 while playing lower tubular column, in the eyelet of lower pin rod 1 reeve elevator ear, slightly applying power, the spring leaf of spring anchor 2 is compressed, the lower ring of spring anchor 2 is pushed and is moved down by spring, arcuate bombing leaf is compressed into the eyelet of elevator ear, spring leaf at the effect lower spring anchor 2 of the elastic force of spring leaf own after the spring anchor goes out the eyelet of elevator ear arches again, on lower ring, moves, and elevator pin just is anchored in the hanger of elevator.When elevator overturns for some reason, because the grappling effect of spring anchor 2 is arranged, the elevator pin rod just can not come off from the pin-and-hole of elevator ear, under the assurance elevator can not come off from suspension ring, does not pound the secondary accident that occurs.Fastened the elevator pin safety rope in becket bridle 4 and tied up on suspension ring, prevented from that it from coming off to hurt sb.'s feelings.Hold the handle of pin rod 3 while getting elevator pin, up exert oneself, the spring leaf of spring anchor 2 is compressed, the lower ring of spring anchor 2 is pushed and is moved down by spring leaf, spring anchor 2 is compressed into the eyelet of elevator ear, and the spring leaf at the effect lower spring anchor 2 of the elastic force of spring leaf own after spring anchor 2 goes out the eyelet of elevator ear arches again, on lower ring, moves, spring anchor 2 resiles, and moves in circles.
