Description
Technical field
The present invention relates to fixing, the handling auxiliary device of lining in Marine engineering, more particularly, relate to fixing, the handling auxiliary device of boats and ships rudder bush and stern tube shaft cover.
Background technology
Marine equipment (particularly main equipment), as: the devices such as rudder bush, stern tube shaft cover need to carry out cooling down before the mounting and reach its amount of contraction, need after cooling to carry out equipment installation immediately, when cooling and installation, need some device to assist handling and installation.
Be installed as example with boats and ships rudder bush, need during lining cold charge to be all placed in low temperature (subzero 193 DEG C) liquid environment, hardening time reaches 40-50 minute, needs to change frock and install in handling to ship after having cooled.Its shortcoming has:
1, change the frock time longer, may cause lining cool after expanded by heating again, cause lining contracts amount to reduce to some extent;
When 2, again changing frock, need to contact rudder bush, low temperature may be caused to scald, there is potential safety hazard;
When 3, changing frock installation, disposablely can not be in place, need many people to carry out coordinative construction, waste time and energy;
4, take the crane time in a large number, cause the significant wastage of productive costs.
Summary of the invention
The present invention relates to equipment of Vessel Vessels in building rudder bush cool and install a kind of auxiliary device used, in equipment of Vessel, the installation location adjustment of stern tube shaft cover also can by this device in addition, and the convenience that raising equipment is installed is with quick.Under the present invention is intended to solve prior art, marine equipment can cool for a long time in ultra-low temperature surroundings, and cooling can directly handling be gone on board and be in place after being reached corresponding amount of compression, and midway does not need again to change auxiliary tooling device.
In order to achieve the above object, the invention provides that a kind of boats and ships rudder bush is fixed, handling auxiliary device, comprise the central concentrated load bar that top arranges suspension ring, described central concentrated load bar upper and lower two place's setting table stages, and utilize the mode of described step and setscrew nut matching thread section to fix two banjo fittings; Upper and lower two described banjo fittings offer four radial tapped bore at the first-class angular distance of ring wall, are connected with leading screw in described tapped bore, the outer end grafting of described leading screw sleeve pipe; The described sleeve pipe other end is a solid stud; The leading screw rod-type that correspondence is rotatably connected in a parallel described central concentrated load bar setting by respective described solid stud mutually of every two upper-lower positions is linked up with, and the lower end of described rod-type hook arranges horizontal hanging structure laterally.Thus have four rod-type hooks, centered by described central concentrated load bar, the mode of being centrosymmetric is arranged, and the low side hanging structure of four hooks is used for the bottom side end face of support sleeve, lining 99 simultaneously.
Under optimal way, there is spring the outside of described sleeve pipe, and one end of described spring leans on described rod-type hook, and the other end is limited by pressing plate by the jam nut be rotatably connected on described leading screw.
The invention has the advantages that, fitting device of the present invention can be general, and energy repeated usage, reduce costs, and adopting that fitting device of the present invention cools equipment, handling and can disposable success when installing, centre does not need again to change auxiliary mould, save trouble and labor, easy to use.

Fig. 4 is the using state structural representation of auxiliary device of the present invention.
Detailed description of the invention
As shown in Figures 1 to 3, for boats and ships rudder bush fixes the structural representation of handling auxiliary device, comprise central concentrated load bar 1, hook 4, screw mandrel 9, suspension ring 10.Described central concentrated load bar 1 is provided with joint 2 and setscrew nut 3, and described joint 2 is connected with screw mandrel 9, and setscrew nut 3 fixes the upper end of described joint 2, and screw mandrel 9 is connected with hook 4 by screw thread; Spring 5, sleeve pipe 8, pressing plate 6 and nut 7 are enclosed between screw mandrel 9 and hook 4; Suspension ring 10 are arranged on the top of central concentrated load bar 1.
By regulate the degree of tightness of 7 nuts on 9 screw mandrels can change 9 screw mandrels and 4 link up with between distance: as fastening nut 7, make the distance between sleeve pipe 8 and screw mandrel 9 elongated by pressing plate 6, and making the distance between sleeve pipe 8 and screw mandrel 9 be elongated to the length of needs and keep-spring pressure by Compress Spring 5, the equipment that needs are installed is in stationary state; As unscrewed nut 7, spring 5 is extended and after losing spring tension, then screw mandrel 9 extend among sleeve pipe 8, make the Distance Shortened between screw mandrel 9 and hook 4, at this time device is in the state of not stressing, and easily can shift out from lining.In sum, just can be made the size to fit of the bearing force between hook and lining by setting nut, held stationary when making lining cooling, handling and install, is unlikely to come off or shift out from lining.This fitting device can be placed among low temperature liquid environment together with lining, can directly handling and install this lining after cooled, and midway does not need again to change auxiliary tooling device.
As shown in Figure 4, for boats and ships rudder bush fixes the use schematic diagram of handling auxiliary device.First the assembly working of this device is carried out: first at the two ends of central concentrated load bar 1, two joints 2 are installed respectively, with setscrew nut 3 lock-on connection 2.Then connect four rhizoid bars 9 respectively at four endoporus of joint 2, form upper and lower two cruciform plans, screw mandrel 9 overlaps successively upper nut 7, pressing plate 6, sleeve pipe 8 and spring 5, make every rhizoid bar 9 have the ability regulating power of shoring.Finally eight rhizoid bars 9 are linked up with 4 be connected with four, form an integrated tooling, and in central concentrated load bar upper end, suspension ring 10 are installed.
The concrete use procedure of this device is as follows: first setting nut 7 is to the inside states that whole device is in contraction, ensures that the outside dimension of frock is less than lining 99 internal diameter size needing handling.Then device is penetrated lining endoporus, tightening nut 7 makes four L-square support bushings 99 bottom hook 4, and ensures that the periphery of hook 4 and the inwall of lining fit tightly.Adjust spring 5 amount of compression finally by nut 7, ensure that upper and lower eight rhizoid bar 9 uniform force are stablized.This device and lining 99 link into an integrated entity like this, carry out the handling installation exercise of lining 99 by suspension ring 10.After handling, again check that the strong point of hook 4 is stressed whether evenly firmly, by nut 7 regulating spring 5 tightness, ensure that lining handling process safety is reliable.Boats and ships rudder bush fixes handling auxiliary device disposablely can complete the cooling of lining 99, handling and installation exercise, and period does not need to change other auxiliary mould.Lining 99 making the outside dimension of whole frock be less than the internal diameter size of equipment by unclamping nut 7, just easily can taking out this fitting device, in order to reusing after installing and terminating.
The invention has the advantages that, safe and reliable during use, do not need artificial directly contact arrangement, avoid the injury that low temperature brings to human body, this device use procedure is flexible, can repeated usage, and any parts can be changed separately if any damage, maintain easily, improve operating efficiency, reduce operating cost.
The above; be only the present invention's preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
