Abstract
The invention discloses a novel safety elevator pin which is characterized in that an upper pin rod and a lower pin rod are connected through a screw thread; an upper ring of a spring anchoring device sleeves the screw thread joint and is limited at the position; a lower circular sleeve can move up and down along the upper pin rod; a handle of the upper pin rod is held by a hand, the lower pin rod is inserted into a pin hole of an elevator lug, and a small force is applied, a spring leaf of the spring anchoring device is compressed so as to push a lower ring to move downwards, as result, the anchoring device is compressed into the pin hole of the elevator lug of the anchoring device; after the spring anchoring device is out of the pin hole, the lower ring of the anchoring device moves upwards under the action of elasticity, as a result, the spring leaf is bended again, and the elevator pin is anchored into the lifting lug of the elevator. Due to the adoption of the technical scheme, in case the elevator is turnover by accident, the elevator pin rods can not drop off from the pin holes of the elevator lug due to the anchoring function of the spring anchoring device; a safety rope ring is welded at the front end of the handle of the upper pin rod, and a protective rope tied with a hoisting ring is tied with the safety rope ring, so as to avoid the situation that the pin rods drop off and damages cause; the elevator pin can be taken off, as long as the handle of the upper pin rod is held by the hand, and an upward force is applied.
Description
Technical field
The present invention relates to when the oil drilling and repairing well plays lower tubular column to inject in the pin-and-hole on the elevator ear, prevent from that elevator from coming off to cause other secondary accident to take place from suspension ring.
Background technology
Up in the derrick space at the oil drilling and repairing well hollow tourist bus that makes a trip, transfer in the process and can bump on the rope that is suspended in the derrick space and some object or the elevator that hangs in the suspension ring when braking suddenly just might overturn because of reasons such as swings, 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, 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
Potential safety hazard at the present used straight-bar elevator pin existence in scene, purpose of the present invention 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 the elevator pin is fixed in the elevator earrings firmly, guarantee that the elevator pin can not come off yet under the situation of elevator upset, guarantee that elevator is not shed to the rig floor face and hurts sb.'s feelings from suspension ring.
The objective of the invention is to finish like this:
A kind of new type of safe elevator pin is mainly by following pin rod, the spring anchor, last pin rod, safe becket bridle is formed, the bottom of last pin rod has screw, the top car of following pin rod has and the screw of the last pin rod screw mandrel with button-type, following pin rod passes the spring anchor and is connected with screw on the last pin rod, the ring internal diameter of going up of spring anchor is slightly larger than the screw mandrel diameter, less than the body diameter of last pin rod and following pin rod and be enclosed within down on the screw mandrel of pin rod, the shoulder place that the upward ring of spring anchor is limited between pin rod and following pin rod can not move up and down arbitrarily, the following ring internal diameter that the spring cat is decided device is slightly larger than the external diameter of pin rod, be enclosed within down on the pin rod and can move up and down, the handle corner of last pin rod is welded with safe becket bridle.
The beneficial effect of advantage of the present invention and generation is:
1, the present invention adopt the assembling of conventional part, simple to operate, can process easily according to various elevator sizes, cost is low, has the advantage of generally using.
2, because adopting compressible and the principle that can the spreading grappling of arcuate bombing leaf, guarantee that the elevator pin can not come off under the situation of elevator upset yet, guarantee that elevator is not shed to the rig floor face secondary accident takes place from suspension ring.
Description of drawings
Fig. 1 is sectional drawing of the present invention.
Fig. 2 is spring anchor of the present invention.
The specific embodiment
As shown in Figure 1, a kind of new type of safe elevator pin is mainly by following pin rod 1, spring anchor 2, last pin rod 3, safe becket bridle 4 is formed, the bottom of last pin rod 3 has screw, the top car of following pin rod 1 has and the screw of last pin rod 3 screw mandrel with button-type, following pin rod 1 passes spring anchor 2 and is connected with screw on the last pin rod 3, the ring internal diameter of going up of spring anchor 2 is slightly larger than the screw mandrel diameter, less than the body diameter of last pin rod 3 and following pin rod 1 and be enclosed within down on the screw mandrel of pin rod 1, the going up the shoulder place that ring is limited in 1 of pin rod 3 and following pin rod and can not move up and down arbitrarily of spring anchor 2, the following ring internal diameter that the spring cat is decided device 2 is slightly larger than the external diameter of pin rod, be enclosed within down on the pin rod 1 and can move up and down, the handle corner of last pin rod 3 is welded with safe becket bridle 4.
Hold the handle of pin rod 3 when playing lower tubular column, applying power slightly in the eyelet of following pin rod 1 reeve elevator ear, the spring leaf of spring anchor 2 is compressed, the following ring of spring anchor 2 is pushed by spring and is moved down, arcuate bombing leaf is compressed into the eyelet of elevator ear, the spring leaf that goes out when the spring anchor behind the eyelet of elevator ear at the effect lower spring anchor 2 of the elastic force of spring leaf own arches again, moves on the following ring, and the elevator pin just is anchored in the hanger of elevator.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 when elevator overturn for some reason, did not pound the secondary accident that takes place under the assurance elevator can not come off from suspension ring.Fastened elevator pin safety rope in the becket bridle 4 and tied up on the suspension ring, prevented from that it from coming off to hurt sb.'s feelings.Hold the handle of pin rod 3 when getting the elevator pin, up exert oneself, the spring leaf of spring anchor 2 is compressed, the following ring of spring anchor 2 is pushed by spring leaf and is moved down, spring anchor 2 is compressed into the eyelet of elevator ear, and the spring leaf that goes out when spring anchor 2 behind the eyelet of elevator ear at the effect lower spring anchor 2 of the elastic force of spring leaf own arches again, moves on the following ring, spring anchor 2 resiles, and moves in circles.
