Abstract
The utility model discloses a standard knot main chord member structure which comprises a main board, main chord members, inclined web members and taper pipes, wherein the main chord members are welded with the main board and the inclined web members to form standard knots, and the taper pipes are connected in an oriented mode through the main chord members between the standard knots. The main chord members serve as main stressed parts of the standard knots, integral rigidity and intensity of a standard knot guide rail frame are improved, abrasive resistance is improved, reliability of products is ensured, and accordingly the service life is greatly prolonged.
Description
Technical field
The utility model relates to a kind of standard knot main chord structure of using in the building hoist of building.
Background technology
At present, existing building hoist standard knot main chord all adopts Φ 76x4.5 seamless tube, its material is 20 steel, because its pipe wall thickness of process limitation of seamless tube is inhomogeneous, standard knot butt joint error is big, and cage operation noise is big, the rigidity of standard knot, stability, wears no resistance, reliability of products is lower, influences product life.
Summary of the invention
The utility model is for solving above-mentioned existing problems, and the utility model provides a kind of novel standard knot main chord structure, makes every performance of building hoist improve.
It is as follows that the utility model solves the problems of the technologies described above the technical scheme of taking:
A kind of standard knot main chord structure comprises: mainboard, main chord, diagonal web member, Taper Pipe, and wherein, described main chord is welded to form standard knot by welding and mainboard, diagonal web member, and wherein, described Taper Pipe is by the connection of leading mutually of the main chord between the described standard knot.
Further, preferred construction is, also is provided with connecting panel and subplate, and described connecting panel and subplate are located between the described standard knot.
Further, preferred construction is that described main chord material is Q345 (16Mn).
The utility model has been taked after the such scheme, and the main chord of described standard knot docks error up and down and reduces, and noise reduces during the cage motion, operates steadily; Owing to use material to be low-alloy steel Q345 (16Mn), the rigidity of standard knot, stability, resistance to abrasion improve greatly, make reliability of products improve, and product life prolongs.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in detail, so that above-mentioned advantage of the present utility model is clearer and more definite.
Fig. 1 is the utility model main chord structural representation;
Fig. 2 is the generalized section of the utility model main chord structure.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.Wherein, Fig. 1 is the structural representation of the utility model standard knot device, and Fig. 2 is the generalized section of the utility model main chord structure.
As illustrated in fig. 1 and 2, shown in the standard knot device comprise: mainboard 1, main chord 2, diagonal web member 3, Taper Pipe 4, connecting panel 5, subplate 6, wherein, described main chord is welded to form standard knot by welding and mainboard, diagonal web member, wherein, described Taper Pipe is by the connection of leading mutually of the main chord between the described standard knot.
And described connecting panel and subplate are located between the described standard knot.
In carrying out preparation process of the present utility model, described main chord is to utilize Q345(16Mn) qualified sheet material by specialized apparatus through cans, dielectric bonding, repeatedly shaping is to reach the uniform qualified welded tube requirement of diameter.
For example, qualified Q345(16Mn) roll bending, combination roller by specialized equipment carries out cans successively, be fit to carry out the dielectric bonding moulding after the requirement when reaching, use special-purpose doctor blade after welding is finished, proofread and correct with the implementation specification product by moulding then, carry out the water-cooled cooling moulding again, be cut at last and expect that the welded tube material changes finishing shop over to and carries out the processing of main chord finished product, finish the production engineering.
The utility model has been taked after the such scheme, and the main chord of described standard knot docks error up and down and reduces, and noise reduces during the cage motion, operates steadily; Owing to use material to be low-alloy steel Q345(16Mn), the rigidity of standard knot, stability, resistance to abrasion improve greatly, make reliability of products improve, and product life prolongs.And, the standard knot of using the main chord structure makes the overall structure of product obtain optimization, actv. has solved the generation that main chord docks phenomenons such as error is big, wall unevenness is even up and down, and reliability of products is guaranteed, thereby makes bulk life time that very big lifting arranged.
It should be noted that; above-mentioned specific embodiment only is exemplary; under above-mentioned instruction of the present utility model, those skilled in the art can carry out various improvement and distortion on the basis of above-described embodiment, and these improvement or distortion drop in the protection domain of the present utility model.
It will be understood by those skilled in the art that top specific descriptions just in order to explain the purpose of this utility model, is not for restriction the utility model.Protection domain of the present utility model is limited by claim and equivalent thereof.
