Abstract
The utility model discloses a flange disassembly and assembly assisting tool which comprises a first semicircular annular fastener, a second semicircular annular fastener and a fastening device. The flange disassembly and assembly assisting tool is characterized in that one end of the first semicircular annular fastener is movably connected with one end of the second semicircular annular fastener in a hinged mode, and the other ends of the first semicircular annular fastener and the second semicircular annular fastener are locked through the fastening device, the size of the inner diameter of the first semicircular annular fastener and the size of the inner diameter of the second semicircular annular fastener are equal to the size of the outer diameter of a flange, and a plurality of bayonets for limiting rotation of nuts or bolts are formed in inner diameter surfaces. When the flange disassembly and assembly assisting tool is used, a lock is arranged on the flange in a meshed mode so as to limit rotation of the nuts or the bolts on one side of the flange, a wrench is used for screwing the bolts or the nuts one by one on the other side, and therefore disassembly and assembly of the flange are completed.
Description
Technical field
The utility model relates to a kind of flange dismounting aid, the bolt on especially auxiliary spanner dismounting ring flange, the instrument of nut.
Background technology
At present, in modern industry, flange is widely used in the fields such as electronics, chemical industry, building, feedwater, draining, oil, weight are industrial, freezing, health, hot-water heating, fire-fighting, electric power, space flight, shipbuilding.
The installation of existing flange is general all by be inserting bolt in the installing hole that regular polygon distributes on two ring flanges, then with nut, bolt is fixed.Dismounting for flange top nut, bolt, generally all also need now two spanners could be by its dismounting, one of them spanner is for twisting bolt head (or nut), and a spanner is for preventing nut (or bolt) the companion rotation of the other end, and two spanners need respectively holding up.So not only use more than instrument but also operate also more loaded down with trivial details, in addition, once the one side operating space of flange hour, need to select suitable spanner just can extend in this space, remove anchor stud head or nut, the not only bad installation of spanner, operating personnel's body is difficult to put in place, dismounting flange is very inconvenient, and labour intensity is large.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provide a kind of simple in structure, use flexibly, and greatly facilitate the flange dismounting aid of flange dismounting.
To achieve these goals, the technical solution adopted in the utility model is: include the buckling body of joining with the outward flange fixed cover of flange, this buckling body is fixedly formed by the detachable splicing of at least two fasteners, the inwall projection of described buckling body is provided with the deck of some projections, is provided with and the nut of flange or the bayonet socket of bolt head rotary spacing on this deck.
Further arranging is that described fastener has two, be respectively the first semicircle annular fastener and the second semicircle annular fastener, the first semicircle annular fastener and the second semicircle annular fastener internal diameter size all equal ring flange external diameter size, one end of described the first semicircle annular fastener and the second semicircle annular fastener is movably hinged, the other end is keyed end, and this keyed end is provided with for locking the retaining mechanism of the first semicircle annular fastener and the second semicircle annular fastener.
In said structure, when two semicircular annular snap fastener is by hasp firm locking on flange time, bayonet socket is corresponding clamps each nut or the bolt head on ring flange, at the opposite side of flange, uses spanner to twist one by one bolt or nut.This flange dismounting aid latches in and on flange excircle face, takes up room littlely, and can from different angle lock, be buckled in flange according to different complex environments, has avoided because the complexity of environment, and has been difficult for the rotation of restriction bolt or nut.Adopt this instrument to limit the rotation of all bolts on ring flange or nut, a people uses a spanner just can complete the dismounting of flange, has reduced labour intensity simultaneously.
Further arranging is that described bayonet socket is arranged on the aperture surface of buckling body equably, and the axial width of bayonet socket is less than the axial width of buckling body, and the number of bayonet socket is corresponding with number and the position of bolt on flange or nut with position.
Further arrange be that described clasp comprises pedestal, hasp movable part, hasp, has contact with, spring and pin key, described pedestal is arranged on the first semicircle annular fastener, described in have contact with and be arranged on the second semicircle annular fastener.This arranges, and the pedestal of clasp and the first semicircle annular fastener are wholely set, and can better strengthen the constant intensity of pedestal and the first semicircle annular fastener.Have contact with and be bolted on the second semicircle annular fastener, having contact with is force part, and thinner, and long-time use easily damaged, and adopts bolt to be fixedly installed and is convenient to change.
Further arrange is that described pedestal and the first semicircle annular fastener are integrated setting.
Further arrange to have contact with to be bolted described in being and be arranged on the second semicircle annular fastener.
Further arrange is that described retaining mechanism is for opening soon bolt device, this is opened soon bolt device and includes the bolt mount pad being fixedly installed on the first semicircle annular fastener, on the second semicircle annular fastener, be provided with the U-shaped seat corresponding with bolt block, on bolt mount pad, hinged being provided with opened bolt soon, and this is opened soon screw thread on bolt and is provided with the friction tight clamping cap of outer end side wall and pressure with U-shaped seat.
Below in conjunction with accompanying drawing, the utility model is further described.
