Description
Technical field
The utility model relates to a kind of specific purpose tool, more particularly, particularly relates to a kind of specific purpose tool dismantling water turbine water guiding vane bearing.
Background technology
The bearing of water turbine water guiding vane is spherical bearing, because bearing being caused to burn to death after a variety of causes damage, cannot dismantle.At present, the conventional method destroying bearing block dismantles bearing.Waste time and energy very much.In addition, after bearing block destroys, must the bearing block that adapts of processing and fabricating again, cause the unit maintenance duration greatly to extend, have a strong impact on the normal power generation in power station.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of specific purpose tool of rational in infrastructure, easy to use and respond well dismounting water turbine water guiding vane bearing.
The technical solution of the utility model is achieved in that a kind of specific purpose tool dismantling water turbine water guiding vane bearing, comprise support plate, the jack relative with rotating shaft is provided with in the middle part of wherein said support plate bottom surface, some guide holders are circumferentially provided with at the support plate H of jack periphery, guide holder is provided with guide through hole, and each guide through hole radially distributes; The support plate that guide through hole is corresponding is provided with the adjustment through hole adapted, pull bar is equipped with in the guide through hole and adjustment through hole of each correspondence, the lower screw rod adapted with water turbine water guiding vane axle bed fixed screw holes is provided with in pull bar lower end, be provided with screw rod in pull bar upper end, upper screw rod has been threaded setscrew nut.
Above-mentioned a kind ofly dismantle in the specific purpose tool of water turbine water guiding vane bearing, the external diameter of described lower screw rod is less than the external diameter of pull bar.
Above-mentioned a kind ofly dismantle in the specific purpose tool of water turbine water guiding vane bearing, described lower screw flight is connected with crossover sub, and described crossover sub lower end is provided with auxiliary threaded rod, and the external diameter of described auxiliary threaded rod is greater than the external diameter of lower screw rod; The external diameter of described auxiliary threaded rod is less than the external diameter of crossover sub.
Above-mentioned a kind ofly dismantle in the specific purpose tool of water turbine water guiding vane bearing, be provided with the positioning sleeve adapted with jack bottom described support plate, be circumferentially with some holding screws at positioning sleeve, each holding screw is relative with jack.
After the utility model adopts said structure, by arranging the lower screw rod adapted with existing water turbine water guiding vane axle bed fixed screw holes on pull bar, pull bar is directly connected with water turbine water guiding vane axle bed by lower screw rod, then by jack and rotating shaft relative motion, pull bar is driven to be pulled out together with bearing by axle bed.Not only operation is very easy, and axle bed need not destroy, and can continue to use, and not only increases inspection speed, and reduce the cost of overhaul.Lower screw rod separates with pull bar and designs, and in conjunction with guide holder and guide through hole, after lower screw rod is screwed into screw completely, can ensure that the entire length of pull bar part is consistent, ensure the uniformity of whole specific purpose tool, there will not be offset problem, determine in the jack course of work, can not occur because specific purpose tool tilts damaging phenomenon.
Accompanying drawing explanation
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but do not form any restriction of the present utility model.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the close-up schematic view at A place in Fig. 1.
In figure: support plate 1, adjustment through hole 1a, positioning sleeve 1b, holding screw 1c, jack 2, guide holder 3, guide through hole 3a, pull bar 4, lower screw rod 5, upper screw rod 6, setscrew nut 7, crossover sub 8, auxiliary threaded rod 9.
Detailed description of the invention
Consult shown in Fig. 1 and Fig. 2, a kind of specific purpose tool dismantling water turbine water guiding vane bearing of the present utility model, comprise support plate 1, the jack 2 relative with rotating shaft is provided with in the middle part of described support plate 1 bottom surface, the positioning sleeve 1b adapted with jack 2 is provided with bottom support plate 1, be circumferentially with some holding screw 1c at positioning sleeve 1b, each holding screw 1c is relative with jack 2.Adopt this structure, jack 2 can be dismantled when not using and deposit, and during use, can be hung again fixing, be easy to operation by holding screw 1c under inverted state.Circumferentially be provided with some guide holders 3 at the support plate 1H of jack 2 periphery, guide holder 3 is provided with guide through hole 3a, each guide through hole 3a radially distributes; The support plate 1 that guide through hole 3a is corresponding is provided with the adjustment through hole 1a adapted, pull bar 4 is equipped with in the guide through hole 3a and adjustment through hole 1a of each correspondence, the lower screw rod 5 adapted with water turbine water guiding vane axle bed fixed screw holes is provided with in pull bar 4 lower end, be provided with screw rod 6 in pull bar 4 upper end, upper screw rod 6 has been threaded setscrew nut 7.Regulating through hole 1a by arranging, instrument of the present utility model can be made, adapt to the dismounting of the shaft bearing of different size dimension.By arranging guide holder 3, playing the object preventing pull bar inclination and offset, ensureing that each pull bar 4 is vertically arranged, uniform force, when avoiding operating, pull bar discontinuity causes the damage of instrument or equipment to be torn open.Meanwhile, in the present embodiment, the external diameter of described lower screw rod 5 is less than the external diameter of pull bar 4.Adopt this structure, when being connected with water turbine water guiding vane axle bed fixed screw holes, only have lower screw rod 5 to enter screw, thus ensure that the length of pull bar 4 is consistent, both convenient adjustment, can prevent again inharmonious between each pull bar 4 and occur the problem that tool damage or part to be demolished damage.
Further, to be threaded crossover sub 8 at lower screw rod 5, described crossover sub 8 lower end is provided with auxiliary threaded rod 9, and the external diameter of described auxiliary threaded rod 9 is greater than the external diameter of lower screw rod 5; The external diameter of described auxiliary threaded rod 9 is less than the external diameter of crossover sub 8.Adopting crossover sub 8, is that the screw in order to make instrument of the present utility model can adapt to more different specification sizes connects.
During use, first the screw in water turbine water guiding vane axle bed fixed screw holes is removed, each lower screw rod 5 correspondence is screwed in water turbine water guiding vane axle bed fixed screw holes, then controls jack 2 and eject, by bearing and bearing block pull-out.
Above illustrated embodiment is better embodiment of the present utility model, only be used for conveniently the utility model being described, not any pro forma restriction is done to the utility model, have in any art and usually know the knowledgeable, if do not depart from the utility model carry in the scope of technical characteristic, utilize the utility model disclose the Equivalent embodiments changing or modify in the done local of technology contents, and do not depart from technical characteristic content of the present utility model, all still belong in the scope of the utility model technical characteristic.
