Abstract
The utility model relates to a drop-proof polish rod clip for production of pumping well, consisting of clip seats 1, 2, clip teeth 3, 4, and a locking steel ring 5, an eccentric locking device 7 and pins 6, 8, 9, which lock the two clip seats and assume a movable connection. The polish rod clip has a reasonable design, a novel structure and a reliable operation. The polish rod clip can be used to greatly reduce accidents of twisted clip, dropped polish rod, improve production efficiency of pumping well and greatly lighten labor intensity of oil production workers, an operation is convenient, time and labor are saved, and good economic benefit is received.
Description
Technical field: the utility model relates to a kind of special-purpose member that rod-pumped well is produced that is used for.
Background technology: the polished rod clamp is the necessary special-purpose member that guarantees the rod-pumped well ordinary production.At present, the various polished rod clamps of field by using are by two decks of bolt and nut locking, with chucking pumpingh well polished rod.Because the card odontotripsis, the fault that clamp strip, polished rod come off often takes place in reason such as bolt pretightening is not enough, load is excessive, has a strong impact on oil well production in the pumpingh well manufacturing process.In addition, existing polished rod clamp also exist installations, maintenance work intensity greatly, shortcoming such as inconvenient operation.
Summary of the invention: the purpose of this utility model is to provide a kind of reliable operation, be difficult for that strip takes place, take off accident and installation, anticreep polished rod clamp easy to maintenance.The utility model is to realize like this.This kind polished rod clamp is by left and right two decks and block tooth, Camlock device, lock steel loop, pin is formed, its structure, assembled relation are as follows: left and right two decks one stress to be provided with pin in the column pin hole of folded matching part is movably connected the two, is respectively equipped with the card tooth in the semicircular arc cylinder groove of two decks middle part; One of deck side is provided with a Camlock device, be provided with the pin that makes it to be movably connected in the column pin hole at the two lap fit position, match with the Camlock device side at position of this deck is provided with a locking steel loop, the steel loop end penetrates column pin hole with pin and makes it to be movably connected with the Camlock device, the locking steel loop rotates with axis pin of column, two decks can be entangled locking.During use, pull the Camlock device and unload the tight steel loop that uncages, two decks are opened; Then, two card teeth are placed two deck fitting face tops, the deck that closes is placed on its seat on the oil pumper polished rod eye, holds the pumpingh well polished rod tightly, will lock steel loop and entangle, locks another sheet deck, makes the reduction of Camlock device handle position.At this moment, the counterclockwise moment of torsion that the pulling force of utilization locking steel loop and the differential seat angle of pin support force produce tightens deck, and oil well can be opened and take out production.In service at oil pumper, PRL strengthens, and the card tooth is under the effect of polished rod friction, move down a very little distance along the deck fitting face, the radius of encircling of card tooth is diminished, thereby reach the purpose of chucking polished rod, and carrying He Yueda, clamping force is big more, reaches reliable anticreep effect.
The utility model is reasonable in design, novel structure, reliable operation, utilize it can significantly reduce the generation that clamp strip, polished rod take off accident, improve pumpingh well production timeliness, also can alleviate oil recovery worker's labour intensity greatly, handled easily, time saving and energy saving, obtain good economic benefit.
Description of drawings: Fig. 1 is structural representation of the present utility model (vertical view).
Fig. 2, Fig. 3 are respectively its elevation and lateral view.
Fig. 4 is the structural representation of card tooth.
The specific embodiment: enforcement of the present utility model is described further below in conjunction with accompanying drawing.
As shown in the figure, the utility model is made up of deck 1,2, card tooth 3,4, locking steel loop 5, Camlock device 7, pin 6,8,9.Wherein, the cuboid that deck 1,2 is two shapes, structure is identical, the middle part is provided with semicircular arc cylinder groove, the two symmetry cooperates, and a Die side respectively is provided with one in order to penetrate the circular hole that pin makes it to flexibly connect mutually.Card tooth 3,4 (see figure 4)s are inverted awl cylindricality, and height is less than deck thickness 6mm, and the semicircular arc cylinder groove of inner cylinder face and deck matches, and is provided with the notched teeth line.Camlock device 7 is and turns a shape, is made of square body and handle two parts, and the body position is provided with two column pin holes, makes it to be movably connected with deck 2 and locking steel loop 5 in order to penetrate pin 6,8 respectively.
