Description
Technical field
The utility model relates to a kind of mechanical flange extension fixtures of power conduit maintenance.
Background technique
It is connecting line that Cigarette Industrial Enterprise, which produces motivational guarantees, the flanges such as too busy to get away water, steam, vacuum, compressed air,
A kind of important spare part, have it is convenient and fast connection, dismantle convenient feature, we are frequently run onto two classes in maintenance process
Problem: one, replacement is directly connected to gasket between flange, valve, actuator between two pieces of two, replacement non-conterminous flanges,
It is flexible coupling.The former operation distance is very close to the tools such as playing with homalocephalus crowbar, punching and be easy to pry open some distances, Huo Zheyong
The common hydraulic flange separator insertion in market presses off；The latter's operation is relatively difficult, and pre- two pieces of separated flanges are at a distance of remote, homalocephalus
Crowbar, jack do not have supporting point.The leading portion of common hydraulic pressure separating device is triangular symmetry structure, and release travel is short, is only applicable in
Separate two flanges interconnected, if replaced the gasket between flange, be not particularly suited for valve between two pieces of non-conterminous flanges,
Actuator, the replacement being flexible coupling.
Utility model content
The technical problems to be solved in the utility model is to provide one kind can strut flange at a distance, easily take out old
The mechanical flange extension fixture of the power conduit maintenance of valve, actuator, the spare part for being flexible coupling and more renewing.
In order to solve the above technical problems, the technical solution adopted by the utility model is:
A kind of mechanical flange extension fixture of power conduit maintenance, including screw rod, the screw rod middle part is helicitic texture,
The left side of the screw rod is connected with right baffle-plate, and right shell body is connected on the right of the screw rod, and the lower part of left baffle and right baffle is inserted
Enter between flange, the right baffle-plate top offers right-handed thread hole, and the right shell body top offers left handed threaded hole, institute
Helicitic texture and the right-handed thread hole and left handed threaded hole in the middle part of screw rod is stated to cooperate.
The right baffle-plate lower part is left wedge-shaped part, and the right shell body lower part is right wedge-shaped part, the left wedge-shaped part and right wedge
Shape portion is oppositely arranged in left and right directions.
Anti-skid structure is provided on the outside of the left wedge-shaped part and right wedge-shaped part.
The anti-skid structure is annular knurl.
The both ends of the screw rod are provided with knob.
The shape of the knob is hexagon.
The utility model has the beneficial effects that
1, applied widely: it is interconnected that the mechanical flange extension fixture of the utility model is not only able to separation two
Method.And the flange that not be coupled to each other can be separated, as replaced the actuator between two panels flange, valve, being flexible coupling, at this time
It needs flange spacing to expand again a little, can easily take out old valve, actuator, the spare part for being flexible coupling and more renewing.
2, be applicable in function to increase: if left baffle and right baffle is commutated simultaneously, left baffle is acted on the outside of flange, together
When rotary screw both ends be able to achieve the effect of compression flange；
3, safe and reliable: mechanical flange extension fixture is only axially making power end face of flange, and flange both ends pipeline is avoided to send out
Raw radial deflection can not centering, cause flange bolt hole to be unable to return phenomenon；Rotary screw, which generates, continues gradual change power, effective protection
Flange face.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the mechanical flange extension fixture of power conduit maintenance of the utility model；
Fig. 2 is the side structure schematic diagram of left baffle and right baffle in the utility model.
Appended drawing reference is as follows in figure: 1- right baffle-plate, 2- screw rod, 3- right shell body, 4- knob, 5- anti-skid structure, the left wedge of 11-
Shape portion, the right wedge-shaped part of 31-.
Specific embodiment
The utility model is further described with reference to the accompanying drawing, following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
As depicted in figs. 1 and 2, a kind of mechanical flange extension fixture of power conduit maintenance, including screw rod 2, screw rod 2
Length can be processed into serial accessory according to actual needs.It is helicitic texture in the middle part of screw rod 2, the left side of screw rod 2 is connected with right baffle-plate
1, the right of screw rod 2 is connected with right shell body 3, and the lower part of right baffle-plate 1 and right shell body 3 is inserted between flange, and 1 top of right baffle-plate is opened
Equipped with right-handed thread hole, 3 top of right shell body offers left handed threaded hole, the helicitic texture at 2 middle part of screw rod and right-handed thread hole and
Left handed threaded hole cooperation.Due to the screw thread in left baffle and right baffle be it is reversed, when rotary screw 2, can be realized left and right
Baffle squeezes flange while moving outward, to have the function that expanded flange distance.
1 lower part of right baffle-plate is left wedge-shaped part 11, and 3 lower part of right shell body is right wedge-shaped part 31, left wedge-shaped part 11 and right wedge-shaped part
31 are oppositely arranged in left and right directions, and being set as wedge structure can facilitate in insertion your beautiful writings gap.
Outside and the flange contact of left wedge-shaped part 11 and right wedge-shaped part 31 are provided with anti-skid structure 5, anti-skid structure 5 above
Preferably annular knurl can increase coefficient of friction, increase the frictional force at left wedge-shaped part 11 and right wedge-shaped part 31 and flange contact.
The both ends of screw rod 2 are provided with knob 4, and the shape of knob 4 is hexagon, convenient to pass through spanner rotary screw 2.
The working process of the utility model is as follows: left wedge-shaped part and right wedge-shaped part are inserted between flange first, then led to
Spanner fixed knob portion is crossed, then rotary screw, in the rotary course of screw rod, left baffle moves outward, reaches expansion
The purpose of flange distance.
The above is only the preferred embodiment of the utility model, it should be pointed out that: for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
