Fig. 2 is the structure sectional view of semicircular ring of the present utility model.
Detailed description of the invention
Below in conjunction with attached Fig. 1 and 2, the utility model is described in detail:
The frock of installing for axle sleeve comprises base 1, clamping device and lowering or hoisting gear.Lowering or hoisting gear is liftably arranged on base 1, and is connected with clamping device, drives clamping device respect thereto to rise or declines.
Clamping device comprises two semicircular ring 2.Two semicircular ring 2 are rotatably connected by articulated elements 7.Two semicircular ring 2 relatively rotate and close, and form an annulus.Two closed semicircular ring 2 are locked together by snap close 3.Two opposing movements of semicircular ring 2, annulus is opened.
The inwall of semicircular ring 2 is provided with multiple projection 4, and projection 4 is along the circumferential direction uniformly distributed.
Semicircular ring 2 is provided with first cavity volume 21.First cavity volume 21 offers three the first openings 22 on the outer wall of semicircular ring 2, and each first opening is equipped with switch (not shown), is used to open or close the first opening 22.
First cavity volume 21 offers multiple second opening 23, second opening 23 and is along the circumferential direction uniformly distributed on the inwall of semicircular ring 2.Second opening 23 is provided with igniter (not shown) and switch (not shown).Switch can open or close the second opening 23.
The outer wall of semicircular ring 2 is provided with thermal insulation layer 5, and thermal insulation layer 5 comprises asbestos.Be arranged with housing 24 outside semicircular ring 2, thermal insulation layer 5 is arranged between semicircular ring 2 and housing 24.
Lowering or hoisting gear comprises support 61, the nut cooperatively interacted and screw rod 62.Support 61 is arranged on base 1.Support 61 is provided with the second cavity volume 611, second cavity volume 611 offers one the 3rd opening the 612, three opening 612 inwall at the top of support 61 and is provided with the screw thread adapted with screw rod 62.Namely threaded 3rd opening 612 is established to be equivalent to the nut matched with screw rod 62.The lower end of screw rod 62 is contained in the second cavity volume 611 through after the 3rd opening 612, and the upper end of screw rod 62 is positioned at the top of the 3rd opening 612, and is connected with clamping device.By rotating screw bolt 62, screw rod 62 is moved up and down on support 61, thus drive clamping device to move up and down on base 1.
Screw rod 62 is also provided with handle 63, and handle 63 is between clamping device and the 3rd opening 612.Active force can be applied to rotary screw 62 on handle 63 by operating personnel, laborsaving and handled easily.
Base 1 is also provided with four rolling 11.When promotion base 1 moves on ground 8, roller can reduce the frictional force between base 1 and ground 8, time saving and energy saving, can improve the stability of frock in moving process of installing for axle sleeve simultaneously.
Using method for the frock of axle sleeve installation is as follows:
Open snap close 3, lift the semicircular ring 2 of top, annulus is opened by two opposing rotations of semicircular ring 2.Axle sleeve 9 to be installed is positioned between two semicircular ring 2, and is supported by the projection 4 in the semicircular ring 2 of below.Put down the semicircular ring 2 of top, closed after making the relative movement of two semicircular ring 2, form annulus.Axle sleeve 9 is clamped by the projection 4 on upper and lower two halves annulus 2.Close snap close 3, upper and lower two semicircular ring 2 are locked together, prevent the two relative movement, avoid axle sleeve 9 to come off.
A pipeline is adopted combustible gas gas storage tanks to be communicated with first opening 22 of semicircular ring 2.Open the switch at this first opening 22 and the second opening 23 place, close the switch at two other the first opening 22 place in semicircular ring 2.First opening 22 of imflammable gas in semicircular ring 2 is passed in the first cavity volume 21, and flows out from the second opening 23.Lighted the imflammable gas flowed out from the second opening 23 by igniter, namely form the flame sprayed towards axle sleeve 9 at the second opening 23, by this flame, axle sleeve 9 is heated.The thermal insulation layer 4 that the outer wall of semicircular ring 2 is arranged can play insulation effect, avoids the temperature of axle sleeve 9 to reduce after-contraction.
Expand after axle sleeve 9 is heated.Promote base 1, the frock being clamped with axle sleeve 9 is moved to the side of furnace roller.Hold handle 63 rotating screw bolt 62, screw rod 52 is moved up and down on support 51, and drive clamping device to move up and down on base 1, the central shaft of axle sleeve 9 is adjusted to concordant with the central shaft of furnace roller.Again promote base 1, axle sleeve 9 is moved towards furnace roller axle journal, axle sleeve 9 is looped around on furnace roller axle journal.
The switch that the first opening 22 that closedown enters for imflammable gas goes out, fray-out of flame, stops heating axle sleeve 9.
Cooling for accelerating axle sleeve 9, being grasped on furnace roller axle journal after making its rapid desufflation firmly, two other first opening 22 in semicircular ring 2 can being communicated with liquid inlet with the liquid outlet of cooling system respectively.Open the switch at above-mentioned two the first opening 22 places, close the switch at the second opening 23 place.Cooling liquid is flowed out from another first opening 22 after one of them first opening 22 flows into the first cavity volume 21, makes axle sleeve 9 fast cooling.
Upper and lower in the utility model is all reference with Fig. 1, for clearly describing the utility model and the relative concept used, does not form the restriction to right.
Embodiment in the utility model, only for being described the utility model, does not form the restriction to right, other equivalent in fact substituting, all in the utility model protection domain that those skilled in that art can expect.
