Abstract
The utility model discloses a tool for mounting a propeller. The tool comprises a tube body (3) with a through hole, wherein opposite screw threads are twisted in holes on two sides of the through hole of the tube body (3) and ended at a middle intersection of the tube body (3); threaded screw rods (2) are screwed in the threaded holes on the two sides; a copper pad (1) is fixed on the top of the outer end of each screw rod (2) by a bolt; and a pin hole is radially formed in the middle intersection of the tube body (3). The tool is used for mounting the propeller, and a phenomenon of danger caused by propeller collision is avoided. The lengths of the two screw rods of the tool can be adjusted freely, and the screw rods are convenient to mount, use and disassemble. According to the tool, the potential safety hazard caused during mounting of the propeller is avoided, and the safety is improved greatly; and furthermore, during construction, the construction efficiency is improved greatly because the tool is light in weight and flexible.
Description
Technical field
The instrument that the present invention relates to use in the shipbuilding process more particularly, relates to and is used for the instrument that screw propeller is installed.
Background technology
Because the distance of screw propeller and stern pipe aft end face has requirement according to marine shafting compound light backguy distance calculation, so in order to guarantee this required distance, after having pressed oar, be pulled to the position apart from the requirement up to specification of stern pipe aft end face to oar with cucurbit.When going out the boats and ships construction now, use the flitch pad mostly,, often cause flitch stuck, need pound flitch with sledgehammer owing to the force rate of hitting oar sometimes is bigger in this position.Both dangerous, operating efficiency is low again.
Summary of the invention
The present invention mainly is the potential safety hazard that causes when mounted for the solution spiral, has improved safety greatly, and, when construction, since light, dexterous, operating efficiency improved greatly.
In order to achieve the above object, a kind of screw propeller mounting tools of the present invention comprises the body that through hole is set; Twisting respectively in the through hole two side holes of said body has oppositely directed screw thread, until position, boundary, middle part; Utilize the tapped bore of both sides to spin respectively and be provided with the leading screw of screw thread, the top, outer end of each said leading screw utilizes bolt that copper packing is arranged.
Under the optimal way, pin-and-hole is radially offered in the position, boundary, said middle part of said body.
Device of the present invention is used for screw propeller and installs, and avoids when hitting oar, occurring dangerous.Two leading screws in the device can freely be adjusted at the length distance, install and use convenient disassembly.The present invention solves the potential safety hazard that screw propeller causes when mounted, has improved safety greatly, and when construction, since light, dexterous, operating efficiency improved greatly.
Description of drawings
Fig. 1 is the running condition structural representation of instrument of the present invention.
The specific embodiment
As shown in Figure 1, screw propeller mounting tools of the present invention comprises body 3; Twist respectively in the through hole two side holes of body 3 oppositely directed screw thread is arranged.It is axis of symmetry left-right symmetric structure that the cross-sectional plane of body 3 is with vertical line of centers, wherein about the longitudinal terminal surface symmetry in two outsides offer horizontal T type bolt hole respectively; Cooperate screw mandrel 2 through said bolt hole, the both sides that are positioned at body 3 are fixed with screw mandrel 2 respectively.Screw mandrel 2 is one and has the flat-bed leading screw, has groove on the platform and is drilled with interior six square bolt holes.Through interior six square bolts copper packing 1 is connected with the screw mandrel upper mounting plate.In addition, pin-and-hole is radially offered in the position, boundary, middle part of body 3; Under the optimal way, at pin-and-hole place grafting revolving bar.
Running condition of the present invention.Have flat-bed screw mandrel 2 with two and be installed in body 3 both sides respectively, copper packing 1 is connected on the screw mandrel 2 through interior six square bolts.During use, note the direction of an end that has copper packing facing to screw propeller.There is not the direction of an end of copper packing facing to the stern tube shaft pipe.Before use, need whether meet the requirements, as do not meet and to rotate two screw mandrel 2, adjust with the yardstick of tape measure instrument.Use light, quick, safe.Two ends are designed with the screw mandrel of positive and negative silk, can free adjusting travel and withdrawing devices, and convenient and practical.Copper packing is used to prevent that screw propeller from damaging.
Two platform-type leading screws of positive and negative cingulum of the present invention can be through bolted connection in the body unit both sides, and convenient disassembly is flexible, in addition, and can free adjusting travel length through rotation.Because entire tool is decomposed form, so, only need the corresponding parts of making to get final product when one when damaged.
Also show propeller hub 4, the blade 5 of screw propeller in addition among Fig. 1, and stern pipe aft end face 6.
The above; Be merely the preferable specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technical personnel of being familiar with the present technique field is equal to replacement or change according to technical scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
Claims (2)
1. a screw propeller mounting tools is characterized in that, comprises the body (3) that through hole is set; Twisting respectively in the through hole two side holes of said body (3) has oppositely directed screw thread, until position, boundary, middle part; The leading screw (2) that utilizes the tapped bore of both sides to spin respectively and be provided with screw thread, the top, outer end of each said leading screw (2) utilizes bolt that copper packing (1) is arranged.
2. according to the said screw propeller mounting tools of claim 1, it is characterized in that pin-and-hole is radially offered in the position, boundary, said middle part of said body (3).
