Abstract
The utility model relates to a Safety clamp for changing packing fittings, which is a simple tool device and plays the role of security protection when the wellhead of an oil pumping unit in the petroleum industry system. The utility model is characterized in that the utility model is composed of a left clamping (1), a right clamping (2), connecting screws and has the advantages of simple structure, easy manufacture, convenient operation, safety assurance, durability, and the improvement of labor productivity and economical benefits.
Description
This sets off when oil pumper well head that card is mainly used in petroleum industry system is changed the rubber packing and plays outstanding packing gland and the packing box pressure cap held of chucking polished rod, plays a kind of simple tools device of safeguard protection.
The on-the-spot oil recovery worker of oil exploitation at present handles packing gland and packing box pressure cap when changing rod-pumped well chewing-gum skin packing method is to check car when waiting for the oil pumper motion near lower dead point position, use manila rope then, perhaps use one on iron wire that packing gland and packing pressure cap bolt is firm, the other end is fixed on the polished rod eye, remove complex operation in this way, and labour intensity is big, non insurance, easily cause the oil recovery worker's that packing gland and packing box pressure cap operating along polished rod downslide cut wound finger, it is big to operate labour intensity in addition, must influence the application life of oil pumper by two people operation, influence the ordinary production of crude oil.
The purpose of this utility model is that development is a kind of simple in structure, the safety factor height, reusable again, the safety of replacing packing annex that again can the one man operation sets off card, eliminate and the sort ofly to carry out heavy and unsafe method of operating, guaranteed safety operation and improved labor productivity with the rope made of hemp or steel wire.
The utility model is to realize like this, mainly crossing screw by left side card and right cartoon forms in succession, be used to install and fix screw at left side card or the external opening sheet of right card one side, left and right card is half recessed ellipse garden shape card body, left and right card card body open front point and card body central point line and axis of pitch are in an acute angle, the outside at left side card or right card is provided with fork, opposite side at left side card, right card is equipped with plug housing, when left and right engaging is held together, then insert plug housing by fork, make the left and right card body can free folding, similar hinge; Respectively have in anti-skidding flexible liner is fixed in left and right card body inboard; Side in addition at left and right card body is connected and fixed by eyelet bolt and butterfly nut, the left and right card body of Zu Chenging just can freely be run jointly like this, the safety that just can constitute a complete replacing packing annex sets off card, and is available at any time and be repeatedly used, not fragile.
Major advantage is that this card has been arranged, but the one man operation that reduces labor intensity guarantees safety, make simple, processing ease, reusable again, experience all sorts of durablely, improved labour productive forces and economic benefit, the worker's that recovered the oil deeply welcome.
Further specify below in conjunction with accompanying drawing, Fig. 1 is the structural representation that the safety of replacing packing annex sets off card, and Fig. 2 is this side-looking assembling schematic diagram that sets off card.
By Fig. 1 and Fig. 2 as can be known, this sets off card mainly by left side card (1), several most of compositions of right card (2) and attachment screw, set off flexible liner (8) in left side card (1) and the right card (2), flexible liner (8) is bonded in right card (1) and the right card (2) for glue-bondable dose, perhaps use screw (5) fixing, left side card (1) and right card (2) are fixed by attachment screw or are opened or close, attachment screw is installed in left side card (1) or right card (2) by bolt (3) and nut (4), and another is made up of eyelet bolt (10) and butterfly nut (7) and packing ring (6) and is installed in left side card (1) or the opposite side of (2) is blocked on the right side; Left side card (1) is connected by pin (9) with the opposite side of right card (2); Left side card (1), right card (2) card body open front point and card body central point line and axis of pitch are in an acute angle; In addition, left side card (1) and right block (2) also can be made by an elastic body, in be processed as anti-skidding netted line; In addition, left side card (1) and right card (2) also can divide in addition to be made by an arc entity, and the inner surface of arc body is processed as anti-skidding netted line (being commonly called as gingival cyst of mucous gland in the newborn button shape) can omit liner (8).
Claims (3)
1. the safety of changing the packing annex sets off card mainly to be made up of left side card (1), right card (2) and several major parts of attachment screw, it is characterized in that setting off flexible liner (8) in left side card (1) and the right card (2), attachment screw is made up of bolt (3) and nut (7) and packing ring (6) and is installed in a left side and blocks (1) or the right side and block a side of (2) and be connected by pin (9).
2, by the safety of the described replacing packing of claim 1 annex set off the khaki feature be left side card (1), right card (2) card body open front point and block body central point connecting line and axis of pitch in an acute angle.
3, the safety by the described replacing packing of claim 1 annex sets off card, it is characterized in that (1) is blocked on a left side and right card (2) also can be made by an arc entity respectively, the arc body inner surface is processed as anti-skidding netted line, and the left side card (1) and the right side are blocked (2) or made by an elastic body.
