When the work of this clamping device, be two flange shapes that first applicable bolt to be replaced are fixed, the convex of size, be fixed on transportable plunger rod termination; Then adjust two distances between connecting rod according to the spacing between two flanges, and connecting rod is fixed on to support bar with clamping screw; Again convex is stuck in to the outer face of two flanges, then by adjusting bolt to carrying out small adjustment between convex and flange.Open pressue device, be connected to plunger rod and pressurize with tracheae by articulation, to reach, two flanges are carried out to fastening object.Finally change normally bolt, bolt is opened relief valve again the pressure in plunger bushing is let out and removed after finishing changing, and finally the clamping screw of connecting rod is removed, and takes off this clamping device.Thereby be issued to the object that equipment bolt is changed not affecting normal production status, improved production efficiency, and protected the service behaviour of equipment.
So the beneficial effects of the utility model have:
1, because the outer end of plunger rod is connected with convex, the shape of convex, size are to select according to pitch-row and the size of two flanges will changing bolt, and wherein circular convex and flange contact facings are long-pending larger, can prevent unbalance stress; Microscler convex is applicable to the less space of pitch-row.Improve the accommodation of this device.
2, in this device, the two ends of connecting rod are all provided with transportable adjusting bolt, can carry out adjustment significantly and by a small margin to the distance between two convexes by clamping screw and adjusting bolt, have facilitated and have used and adjust spacing.
3, plunger rod is enclosed within plunger barrel and can moves around, plunger rod not the used time can be by plunger rod indentation sleeve in, one can save space, two can prevent that plunger rod is aging and be out of shape.
4, the limiting plate that is respectively equipped with restriction plunger rod activity due to the upper and lower end of plunger barrel inwall, has limited ultimate range and the minimum range of plunger rod displacement, and has ensured that in the time of spacing plunger rod there will not be the phenomenon of skew.
5, in this device, be divided into three branches from the gas circuit of pressue device, two are removed respectively two plunger rods, and the 3rd is removed relief valve, completing after the operation of replacing bolt and can pressure being released by pressure release valve port, facilitate the dismounting operation of this device.
6, the outlet side of pressue device is connected with tracheae by articulation, is conducive to the dismounting of pressue device, and is convenient for carrying; On tracheae, check (non-return) valve is conducive to gas and in pressure process, is unlikely to backflow; Pressure gauge is conducive to determine according to the pressure of flange the size of pressurization.
7, pressue device upperpush rod below is provided with support bar, thereby can decide according to the pressure between flange the size of pressurization, is unlikely to hypotony or too highly causes unnecessary impact.
