Description
Technical field
The utility model relates to a kind of nut erecting tools, particularly a kind of nut erecting tools that is applied to the medium-and-large-sized nut installation procedure of shipbuilding industry.
Background technology
Especially in shipbuilding industry, from requirement of engineering, need the workman that nut is installed on the screw element through rotation sometimes from bottom to top in heavy industry journey industry, when heavy nut was installed, adjustment will be a problem very much when embedding screw thread.For instance; When rudder stock is installed; Workmen's often need to weigh nut about 1.5 tons rotates up and is installed on the rudder stock screw thread, and common way is with crane nut to be sling, and 4 above workmens finely tune unsettled nut; Make it to adapt to threaded engagement, rotate unsettled nut together by the workmen again.Like this, the installation procedure of nut not only bothers but also is dangerous, when nut and rudder stock threaded engagement are incorrect; Workmen's ground adjusting position repeatedly of having to waste time and energy; Nut is correctly assembled, and at this moment, personnel also will bear the danger of nut from the suspension accidental.
Those skilled in the art are devoted to find out a kind of economical and practical nut erecting tools, can assist workmen's safe and convenient ground to accomplish the nut installation procedure.
The utility model content
The technical problem that the utility model will solve is the heavy-duty thread part is installed in the prior art is from bottom to top wasted time and energy in order to overcome, and it is many to take staff, and dangerous high deficiency provides a kind of nut erecting tools, accomplishes the screw element installation procedure efficiently.
The utility model solves above-mentioned technical problem through following technical proposals:
A kind of nut erecting tools; Its characteristics are: comprise a flanged screw mandrel, a holding nut, a bearing block, a bearing and the concentric cushion block of a nut, wherein, said flanged screw mandrel, holding nut, bearing block, bearing and the concentric cushion block of nut are placed with one heart; Said holding nut is connected with flanged wire rod thread; Said holding nut supporting bearing base, said bearing is arranged on the bearing block, and the concentric cushion block of nut is arranged on the bearing.
Preferably, also comprise a fairlead, said fairlead is arranged on the flange of flanged screw mandrel.
Preferably, said holding nut side is provided with rotating hole.
Preferably, the quantity of said rotating hole is 6.
Preferably, it is characterized in that: said flanged screw mandrel material is a steel.
In the utility model, but above-mentioned optimum condition combination in any on the basis that meets this area general knowledge promptly gets each preferred embodiment of the utility model.
The positive progressive effect of the utility model is: this nut erecting tools is simple in structure, and is cheap, and it is time saving and energy saving to use, and saves staff, improves the job safety coefficient greatly.
Description of drawings
Fig. 1 is the structural representation of the nut erecting tools in the preferred embodiment of the utility model.
The specific embodiment
The embodiment of the utility model will describe with reference to accompanying drawing.In Figure of description, element or device with similar structures or function will be used the components identical symbolic representation.Accompanying drawing for the ease of each embodiment of explanation the utility model, is not to carry out the explanation of exhaustive to the utility model just, neither limit scope of the present invention.
Be illustrated in figure 1 as a preferred embodiment of the utility model.In this embodiment; The nut erecting tools comprises a flanged screw mandrel 1, a holding nut 2, a bearing block 3, a bearing 4, the concentric cushion block 5 of a nut and a fairlead 7; Wherein, said flanged screw mandrel 1, holding nut 2, bearing block 3, bearing 4, the concentric cushion block 5 of nut and fairlead 7 are placed with one heart.
Flanged screw mandrel 1 is a screw element, is generally steel, and the screw mandrel upper end is provided with a flange 11, is used to place fairlead 7.The diameter of flange 11 is looked the internal thread diameter of nut to be installed 6 and is decided.In general, flange 11 diameters can make the fairlead position that is provided with above that deviation does not take place, thereby the constraint that makes nut 6 can receive fairlead 7 gets final product.
Holding nut 2 is provided with internal thread, with flanged screw mandrel 1 through being threaded.Holding nut 2 sides are provided with several rotating holes 21, and these rotating holes 21 are used for inserting rod iron, are convenient to the workman and as lever holding nut 2 are rotated.In a preferred embodiment, the quantity of rotating hole is 6.
Bearing block 3 is placed on the holding nut 2, and the central through hole of bearing block 3 is not established screw thread, and its internal diameter is greater than the external diameter of flanged screw mandrel 1.Be placed with bearing 4 above the bearing block 3, in the present embodiment, bearing 4 is a plane bearing.
Bearing 4 tops are provided with the concentric cushion block 5 of nut.The concentric cushion block 5 radial outside circumference of nut top is provided with recess according to the internal diameter size of bearing 6, is used for placing bearing 6, in order to avoid bearing slides on the concentric cushion block 5 of nut.Like this, bearing 6 is placed on the concentric cushion block 5 of nut, receives the constraint of fairlead 7 simultaneously, and the axial direction of its axial direction and screw mandrel is consistent.
When concrete the use, center tapping on rudder stock 8 earlier forms prepackage hole 81.For example, when the rudder stock external diameter was 425mm, the external diameter of flanged screw mandrel can be 80mm, and the center tapping forms internal thread on rudder stock 8, and its internal diameter cooperates consistent with the outer-diameter threads of screw mandrel 1.With crane nut 6 is sling and to be suspended at the lower end of rudder stock 8; Parts such as flanged screw mandrel such as diagram are combined, and through the screw of nut 6, the screw mandrel upper end is through being threaded into the prepackage hole 81 of rudder stock 8 from bottom to top; Put down nut 6 gradually this moment, drops on the concentric cushion block 5 of nut.Because nut 6 weight are huge, the concentric cushion block 5 of holding nut 2, bearing block 3, bearing 4 and nut stiction each other is also very big.This moment, screw mandrel was fixedly mounted on the rudder stock 8 through screw thread, and the workmen inserts rotating hole 21 with rod iron, came nut 6 is carried out up-down adjustment through rotation holding nut 2, and the workmen is the screw thread rigging position of adjusting nut 6 and rudder stock 8 more at leisure.When the threaded adjusting end, the workmen screws in rudder stock 8 by the effect of bearing 4 and holding nut 2 with nut, installs and finishes.
Though more than described the specific embodiment of the utility model, it will be understood by those of skill in the art that these only illustrate, the protection domain of the utility model is limited appended claims.Those skilled in the art can make numerous variations or modification to these embodiments under the prerequisite of principle that does not deviate from the utility model and essence, but these changes and modification all fall into the protection domain of the utility model.
