Abstract
The utility model discloses a flange splitting device. The flange splitting device comprises a frame consisting of two beams and two studs; at least one beam is movable; unthreaded holes are formed at the two ends of the movable beam and are in slide fit with the two studs; nuts are arranged on the studs on the outer side of the movable beam; and opposite cutting edges are fixed on the inner sides of the two beams. The flange splitting device has the advantages of simple structure, portability, flexible use and low manufacture cost. A flange to be split is placed between the two cutting edges and is split very conveniently only by rotating the nuts through a wrench. When the dismantlement of pipe flange connecting equipment is in operation, the simple and practical operating performance of the flange splitting device ensures that the operation can be greatly accelerated, the manual labor is saved, and the work intensity is reduced for constructors. As a crow rod is no longer needed for prying, the risk factors in the construction process are eliminated, thereby improving the security.
Description
Technical field
The utility model relates to a kind of device that is used to dismantle the flange connection device.
Background technology
In pipeline maintenance construction, the pipe flange connection device often takes place as (valve, flowmeter etc.) and pipe flange clamping connection tension, or because the flange connect hours is longer, pipe flange often becomes rusty extremely together, is difficult to remove from pipeline.The general now construction method that adopts is to insert the adpting flange slit with crow bar, prizes with manpower to enlarge the gap, and pipe flange connection device and pipeline are broken away from.
The shortcoming that the method exists is: 1, need to prize simultaneously with several manpowers, effort.Easily hit, dodge the danger of bumping the workmen when 2, using crow bar.3, use crow bar to be subjected to field operation space (as eminence, narrow position) restricted influence, speed is slow.
China's utility model patent 200720032726.9 discloses a kind of flange separator of pipe flange fast assembling-disassembling, it has an oil cylinder, taper is installed in the end of oil cylinder separates head, bolt hole location with flange, the taper cutting edge of separator is inserted in the middle of two flanges that will separate the flange separation that the thrust of utilizing oil cylinder to produce will become rusty dead.It is power that this flange separator adopts oil cylinder, and structure is complicated, manufacturing cost is high; Need to be equipped with hydraulic system in use, therefore use inconvenience.
The utility model content
The technical problems to be solved in the utility model provides a kind of safer, flange part removal tool easily.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of flange device of riving, comprise by two crossbeams and two frameworks that double-screw bolt is formed, at least one crossbeam is moved cross beam, the two ends of moved cross beam are provided with unthreaded hole and are slidingly matched with two double-screw bolts, the double-screw bolt in the moved cross beam outside is provided with nut, and the inboard of two crossbeams is fixed with relative blade.
Preferably, two crossbeams are moved cross beam.
Preferably, two crossbeams are made by half rounds.
Preferably, described blade is a wedge.
The beneficial effects of the utility model are: simple in structure, easy to carry, use flexibly, make that this is low.Flange to be separated is placed between two blades, only need just flange can be separated with the spanner rotating nut, it is very convenient to use.When the dismounting operation of carrying out the pipe flange connection device, the simple and practical operating characteristics of the utility model can improve the speed of operation greatly, saves manpower, reduces workmen's working strength.Help crow bar to prize owing to no longer need relend, eliminated the hazards of work progress, improved security.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the rive structural representation of device of the utility model flange.
Fig. 2-Fig. 4 shows and utilizes the utility model that adpting flange is carried out separating process.
The specific embodiment
As shown in Figure 1, a kind of flange of the utility model device of riving is a frame structure, and this framework is made up of 1,3 and two double-screw bolts 2,4 of two crossbeams, and the inboard of two crossbeams 1,3 is fixed with relative blade 5,6.
In the present embodiment, two crossbeams 1,3 are made by half rounds, respectively weld a wedge on the plane of two crossbeam 1,3 inboards, and the wedge angle of two wedges is relative, constitutes described blade 5,6, and wedge is made by the high rigidity bearing steel.The two ends of crossbeam 1,3 are provided with unthreaded hole, and two double-screw bolts 2,4 pass from unthreaded hole, thereby two crossbeams 1,3 all can slide along two double-screw bolts 2,4, that is to say that these two crossbeams 1,3 are moved cross beam, and the double-screw bolt in the crossbeam outside is provided with nut 7.
Below using method of the present utility model is described.
Shown in Fig. 2-4, earlier a moved cross beam 3 is pulled down, framework is enclosed within the outside of flange 8 to be separated, reinstall crossbeam 3, make two blades face slit between the flange 8 to be separated, nut then screws up with a wrench, moved cross beam is moved, blade closes up up and down, and the slit between the adpting flange is progressively enlarged until riving by blade, thereby reaches the purpose of removing the pipe flange connection device.
Be readily appreciated that if wherein crossbeam 1 and two double-screw bolts 2,4 are for fixedlying connected, to have only a crossbeam 3 to be moved cross beam, can realize the purpose of this utility model equally, this structure also should be within protection domain of the present utility model.
Claims (4)
