Description

Container crane suspender integral production method

Technical field

The present invention relates to a kind of container crane suspender integral production method.

Background technology

The existing container spreader in harbour generally all is to adopt machined to process axis hole and otic placode hole on the little end carriage earlier at present; And diameter is all put the surplus of 20mm; With after little end carriage in both sides and the both sides side bar integral manufacturing welding completion, overall structure is through planer-type milling machine boring processing axis hole and otic placode hole and plane during structure fabrication, thus the size conforms drawing requirement in assurance axis hole and otic placode hole; Because the difficulty in whole machined axis hole and otic placode hole is bigger; And the relative distance between each axis hole is difficult for guaranteeing, therefore makes comparatively difficulty, can not well guarantee the precision of suspender after making.

Summary of the invention

The objective of the invention is in order to overcome above deficiency, provide a kind of making simple, guarantee the container crane suspender integral production method of suspender precision.

The object of the invention is realized through following technical scheme: a kind of container crane suspender integral production method may further comprise the steps:

A, making suspender auxiliary mould:

A, two first square tubes of preparation and two second square tubes; Two first square tubes and two second square tubes are fixed into rectangular base frame through welding; On four angles of underframe, all weld stand apparatus; Two anterior stand apparatus are hold-down support, and two stand apparatus at rear portion are the adjusting bearing that is used to carry out four direction fine setting all around;

B, on the position between two said stand apparatus, all weld two bracing frames two first square tubes respectively, all weld side bar at the upper surface of four bracing frames and support, the upper surface that each side bar supports is equipped with groove;

C, in two hold-down supports and two adjusting bearings, all insert plug; Four plugs are fixed respectively; Guarantee that four plugs are parallel to each other, and perpendicular with the bottom surface, and using the diagonal distance between the tape measure plug is 5169 ± 2mm; Horizontal range length is 5000 ± 2mm, and wide is 1310 ± 1mm to distance;

B, making suspender:

A, two side bars of preparation and two little end carriages;

B, two plugs placing with front and back are respectively with two small end beams location and fixing;

C, two side bars are placed on respectively in the groove of front and rear part; Through regulate two adjusting bearings carry out front and back and about between the fine setting; Thereby guarantee that the gap between two little end carriages and two side bars is 1～2mm; Adopt spot welding that two little end carriages and two side bars are fixed earlier, and then two little end carriages and two side bars are welded;

D, between the middle part of two side bars, be welded to connect part;

E, with welding the otic placode of placing before and after two on two little end carriages respectively.

The present invention compared with prior art has the following advantages: assemble then through suspender being made into group's making moulding, reduced whole mach difficulty, improved structure fabrication efficient; Improved production efficiency simultaneously; Control through using the adjusting bearing to carry out the fine setting of four direction all around, thereby carry out whole erection welding, improved efficient; Practice thrift cost, satisfied equipment performance.

Description of drawings:

Fig. 1 is the structural representation of auxiliary mould;

The structural representation that the suspender of Fig. 2 is whole

Label among the figure: 1-first square tube, 2-second square tube, 3-hold-down support, 4-regulate bearing, 5-bracing frame, the support of 6-side bar, 7-groove, 8-plug, 9-side bar, the little end carriage of 10-, 11-connector, 12-otic placode.

The specific embodiment:

In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.

Show the specific embodiment of a kind of container crane suspender of the present invention integral production method like Fig. 1 and Fig. 2, may further comprise the steps:

A, making suspender auxiliary mould:

A, two first square tubes 1 of preparation and two second square tubes 2; Two first square tubes 1 and two second square tubes 2 are fixed into rectangular base frame through welding; On four angles of underframe, all weld stand apparatus; Two anterior stand apparatus are hold-down support 3, and two stand apparatus at rear portion are the adjusting bearing 4 that is used to carry out four direction fine setting all around;

B, on the position between two said stand apparatus, all weld two bracing frames 5 two first square tubes 1 respectively, all weld side bar at the upper surface of four bracing frames 5 and support 6, each side bar supports 6 upper surface and is equipped with groove 7;

C, in two hold-down supports 3 and two adjusting bearings 4, all insert plug 8; Four plugs 8 are fixed respectively; Guarantee that four plugs 8 are parallel to each other, and perpendicular with the bottom surface, and using the diagonal distance between the tape measure plug is 5169 ± 2mm; Horizontal range length is 5000 ± 2mm, and wide is 1310 ± 1mm to distance;

B, making suspender:

A, two side bars 9 of preparation and two small end beams 10;

B, two plugs 8 placing with front and back are respectively with two small end beams, 10 location and fixing;

C, two side bars 9 are placed on respectively in the groove 7 of front and rear part; Through regulate two adjusting bearings 4 carry out front and back and about between the fine setting; Thereby guarantee that the gap between two small end beams 10 and two side bars 9 is 1～2mm; Adopt spot welding that two small end beams 10 and two side bars 9 are fixed earlier, and then two small end beams 10 and two side bars 9 are welded;

D, between the middle part of two side bars 9, be welded to connect part 11;

E, with welding the otic placode of placing before and after two 12 on two small end beams 10 respectively.

Preparation method of the present invention is assembled through suspender being made into group's making moulding then, has reduced whole mach difficulty, has improved structure fabrication efficient; Improved production efficiency simultaneously; Control through using the adjusting bearing to carry out the fine setting of four direction all around, thereby carry out whole erection welding, improved efficient; Practice thrift cost, satisfied equipment performance.
