Abstract
The utility model relates to an instrument of dismouting pipe fitting. The hydraulic pliers mainly comprise an upper pliers mouth, a lower pliers mouth, a screw rod, a nut, a hydraulic cylinder, a handle, a hydraulic handle and the like. The utility model discloses when using, only need revolve half a circle of nut, then the push-and-pull lead screw, can fix a position, hold handle and hydraulic handle simultaneously with the hand, can operate. The utility model discloses the location is fast, the chucking pipe fitting is firm, work efficiency is high, easy and simple to handle, long service life, is the renewal product of traditional breakout tongs.
Description
The utility model belongs to a kind of instrument that loads and unloads pipe fitting.
Pipeline install from not pipe wrench, the pipe wrench of prior art mainly comprises upper clamp nozzle, lower clamp nozzle, adjustment nut and handle etc., it is to adjust the open size of jaw by adjusting nut.Its main weak point is: during use jaw transferred to open to snap on the pipe fitting, nut is adjusted in turn allows upper and lower jaw block pipe fitting, screw then or unscrew pipe fitting, because of the tight ness rating of bit contact pipe fitting is undertaken by tuning whole nut, so block to such an extent that be not too tight generally speaking, so that in operating process, pipe wrench slips out, also can hinder arm sometimes.Because the opening and closing of jaw need the adjustment of turn nut, locate slowlyer, so operating efficiency is lower.
The purpose of this utility model is a kind of novel pipe wrench of design, this pipe wrench simple operation, and can more closely tighten pipe fitting, and can locate fast.
Structure of the present utility model as shown in the figure, it mainly comprises upper clamp nozzle (1), lower clamp nozzle (3), screw mandrel (4), nut (5), guide rod (6), spring (7), piston (9), hydraulic cylinder (10), hydraulic cylinder (12), guide rod (13), handle (17) and hydraulic pressure handle (16).Its key is: in lower clamp nozzle (3) back one rhizoid bar (4) is arranged, screw mandrel (4) links to each other with guide rod (6) through nut (5), piston (9) in guide rod (6) and the hydraulic cylinder (10) links to each other, and at the head end of guide rod (6) return spring (7) is arranged; Hydraulic cylinder (10) and hydraulic cylinder (12) are installed side by side, link to each other by crossing hydraulic fluid port (11) between hydraulic cylinder (10) and the hydraulic cylinder (12), in piston guide rod (13) rear end a fulcrum (15) is arranged, fulcrum (15) can slide in the chute (14) of hydraulic handle (16).Screw mandrel (4) is similar with prior art, be flat, respectively there is a circular arc top and bottom and has screw thread, are second structure, in order to make operation location fast, the internal thread that is mated nut (5) also is half, remainder is a unthreaded hole, and with nut (5) rotation half-turn, screw mandrel (4) just can stretch in guide rod (6), rotate half-turn behind the location again, can tighten.Fulcrum (8) and fulcrum (15) all are located on the hydraulic handle (16).Fulcrum (8) is in order to rotate hydraulic handle (16); Fulcrum (15) enters in the hydraulic cylinder (10) with the hydraulic oil that promotes in the hydraulic cylinder (12) in order to support piston guide rod (13).On caliper of the present utility model, there is an elongated slot (2) at the position that contacts with lower clamp nozzle (3), and lower clamp nozzle (3) can slide therein.In addition, tighter for the pipe fitting card is got, lower clamp nozzle can have certain radian.
Operation principle of the present utility model is: unscrew nut (5) earlier, push-and-pull screw mandrel (4), make lower clamp nozzle block pipe fitting, use the hand push lower clamp nozzle, make it be adjacent to pipe fitting, fastening nut (5), grasp handle (17) and hydraulic handle (16) then, slightly firmly inwardly push away simultaneously hydraulic handle (16), at this moment the hydraulic oil in the hydraulic cylinder (12) is by in the piston PF cylinder pressure (10), and the hydraulic oil in the hydraulic cylinder (10) promotes piston (9) again, and then promotion guide rod (6) moves forward, guide rod (6) is through screw mandrel (4) push-tight lower clamp nozzle, and at this moment pipe fitting is tightened, and operating grip (17) can be operated then.After the end of operation, under the effect of return spring (7), the piston in two hydraulic cylinders is got back to original position.
The utility model has the advantages that: can locate fast, the chucking pipe fitting is firm, long service life, and easy and simple to handle, the efficient height is the replacement instrument of traditional pipe wrench, is fit to boiler erection, pipeline installation and maintenance and uses.
