Detailed description of the invention
As shown in the figure, jib of the present invention, be the strip steel beam column of the similar rectangle of cross section, two ends are manufactured with respectively for hinged axle sleeve hole (being provided with axle sleeve in hinge hole).Its manufacture method, carry out according to the following steps successively:
1) side plate 2, base plate 3, top board 1 is made respectively
Length due to side plate, base plate and top board reaches ten to tens of rice, needs to adopt less steel beam column to be spliced to form respectively.
Side plate is wherein spliced (component of more than 2 also can be adopted to be spliced to form) by the large end 2-1 of side plate and side plate small end 2-2; The large end of side plate and side plate small end all need through punching in advance and machined, to meet design requirement; Then seam alignment as shown in Figure 3, then the side plate be connected as a single entity is formed by welding.For ensureing the joining quality between the large end of side plate and side plate small end, enhancing productivity, side plate frock 12 (shown in Figure 12) can be adopted; Figure 12 shows the duty of side plate frock.
Base plate 3 is wherein spliced to form (component of more than 3 also can be adopted to be spliced to form) by base plate front end 3-2, base plate middle-end 3-1 and base plate rear end 3-3; Base plate front end, base plate middle-end and base plate rear end all need through punching in advance and machined, to meet design requirement; Then seam alignment one by one as shown in Figure 4, then the base plate be connected as a single entity is formed by welding.For ensureing base plate large end, joining quality between base plate middle-end and base plate small end, enhancing productivity, base plate frock 11 (shown in Figure 10) can be adopted; Figure 11 shows the duty of base plate frock.
Top board 1 is wherein spliced to form (component of more than 3 also can be adopted to be spliced to form) by top board front end 1-2, top board middle-end 1-1 and top board small end 1-3; The large end of top board, top board middle-end and top board small end all needed punching in advance and machined, to meet design requirement; Then seam alignment one by one as shown in Figure 2, then the base plate be connected as a single entity is formed by welding.For ensureing top board large end, joining quality between top board middle-end and top board small end, enhancing productivity, top board frock 10 (shown in Fig. 8) can be adopted; Fig. 9 shows the duty of top board frock.
Above-described machined, comprises plasma cut, bending and other intermetallic composite coating adopting special equipment to carry out.
The inner reinforced plate assembly 5 (shown in Fig. 6) that the present invention adopts, is fixed as one by multiple weld parts through preprocessing; This inner reinforced plate assembly is directly provided by upstream firm usually.
2) casing group pair
Gantry sucker loop wheel machine is adopted base plate to be lain in desired location on base plate positioning tool (because base plate is curved surface, rear formation is connected mutually by multiple plane, need base plate positioning tool (i.e. jacking trolley 16) to support to make each position of base plate form differing heights, reach the standard of required curve form; Then by gantry sucker loop wheel machine, inner reinforced plate is lifted on base plate, then two side plates are symmetrically stood in inner reinforced plate both sides and by inner reinforced plate about clamping (side plate positioning tool can be adopted to carry out group case, two side plates are located by side plate positioning tool respectively, to ensure curve form and the positional precision of side plate), last spot welding (recommending by Robot Spot Welding) is fixed, and casing semi-finished product B side plate, base plate and inner reinforced plate being formed be connected as a single entity (as shown in Figure 5; The duty of jacking trolley is shown) in Figure 15, Figure 16;
When adopting described side plate positioning tool 15 pairs of side plates to position, first two, left and right side plate is placed on side plate positioning tool and carries out horizontal location, and fixed by the multiple electromagnetic actuations on side plate positioning tool, so latter two side plate is driven by side plate positioning tool and rotates 90 degree symmetrically and (to rotate around horizontally disposed axis respectively; This axis is parallel with the length direction of side plate), become state shown in Figure 13, Figure 14; Undertaken docking and being welded and fixed by jacking trolley lifting base plate again.
3) interior seam welding
Adopt be welded and fixed at side plate, gap, the inner side place that connects between two between base plate with inner reinforced plate, then carry out scarfing cinder paint; Wherein during interior seam welding, first clamp the half-finished two ends of casing (shown in Figure 17) respectively by the positioner 17 on both sides, then casing semi-finished product are turned over turnback (namely base plate turns to the top, and top uncovered completely down; Be beneficial to welding employee operation, be conducive to scarfing cinder simultaneously), then carry out artificial electric welding.
4) top board group case
Casing semi-finished product after having welded return turnback and return to top board up position; Then adopt gantry sucker loop wheel machine, by top board exact placement at the casing semi-finished product top through paint, then adopt spot welding top board to be fixed on (structure after group case as shown in Figure 7) on casing semi-finished product.
5) wrapper sheet is shaping
Because jib two ends are the hinged end being shaped with hinge hole, end is the face of cylinder that bus is parallel to horizontal plane; And through step 4) being fixed on the top board on casing semi-finished product top, two ends are plane and extend in outer not half-finished two ends inclusion with casing; Equally, base plate two ends are also plane and extend in outer not half-finished two ends inclusion (shown in Fig. 7) with casing; All need to be solved by wrapper sheet molding procedure.
Concrete production method carries out high-temperature heating, makes base plate bending two ends and envelope the large small end head at jib two ends, then adopts electric welding to fix; The two ends of top board so process too.Processing mode, can while adopt welding gun high-temperature heating, while the mode of knocking with hammer, or the mode bent is carried out in the heating of employing intermediate frequency heater, mechanical compression, make top end and base plate two ends bend along the shape of jib end and envelope the large small end head at jib two ends, finally adopt electric welding to fix (structure after processing as shown in Figure 1).
6) axle sleeve is made
At the side of the large small end head in jib two ends cutting (namely cutting respectively on the side plate of both sides) axle sleeve hole 2-5, then in axle sleeve hole, inlay axle sleeve, then electricity consumption weldering fixed hub (omission of figure bottom bracket axle);
7) outer seam welding
To top board, between base plate with side plate, the outer surface gap of parts connecting part is welded and is made it fixing between two; This operation adopts electric welding robot to complete.
