Description

Antirolling pillar jig

Technical field

The present invention relates to a kind of landing slab pillar moulding bed, belong to the shipbuilding technology field.

Background technology

Shipyard generally generally uses fixedly moulding bed when making segmentation.According to conventional segmentation add up the long 10m of every making * wide 10m * high 0.8m fixedly moulding bed need the cost

The about 145m of 100 * 100 * 10 angle steel, the about 40m of-100 * 10 band steels amount to about 2.1 tons of weight.According to 3450 yuan/ton of existing section bar market flat fares, amount to 7200 yuan of RMB, do not take into account wlding and labour cost as yet.Calculate according to every long 20m of ship standard moulding bed * wide 20m, it is 92.0 ten thousand yuans that 32 these moulding beds of single ship making need auxiliary materials expense; Make 12 ships per year and calculate, about 1,100 ten thousand yuans of required auxiliary materials expense, cost is huge.Because bow stern, cabin segmentation, other plate segmentation moulding bed upper thread shape are often bigger, fixedly the moulding bed expense is higher in making.And use fixedly moulding bed, segmentation moulding bed face something that gives the game away is many, and repairing polishing workload is big.And use pillar moulding bed, owing to itself limitation, often only be applicable to linear less segmentation or make the flat-tyre frame, after the moulding bed height surpasses 1400mm, the pillar shakiness, the moulding bed rigidity is not enough, and especially landing slab is easy to cause the pillar bending in the process of standing up, be difficult to meet the demands, damage easily and the maintenance cost height.

Summary of the invention

The object of the present invention is to provide that a kind of rigidity is big, the pillar moulding bed of low cost of manufacture easy care, can make all curved segmentations.Solve the fixedly moulding bed cost height of prior art, the general not enough problem of the rigidity of pillar moulding bed.

In order to solve the problems of the technologies described above, the present invention has taked following technical scheme:

Pillar is linked to each other by two inside and outside footpaths of steel pipe and is welded, one cover spiral chieftain is set on described pillar top, on pillar, set up the pillar eye plate of four mutual vertical symmetry, pillar eye plate cylinder lever connecting rod, utilize described pull bar to interconnect pillar eye plate on each pillar all around, making every adjacent four pillars is one group, connects into the integral body of a rigidity.

Pedestal is made up of seat pipe and interior pipe, and the pedestal end opening is symmetrical arranged the bracket of four bands perforate, and pedestal links to each other with bracket, and pedestal leaves the gap in ground.Two through holes that are mutually 90 degree are set below the pedestal top, and described through hole tacks with latch, and the latch on the pedestal of the adjacent struts bottom of each row and each row is mutually 90 degree.

On described spiral chieftain end thread groove, bead is set.

Described pull bar is middle tapped sleeve, and the pull bar two ends are two equidirectional externally threaded screw rods, and screw rod is connected by bolt with the pillar eye plate.

The present invention is applicable to that making is bow stern, the cabin segmentation of basal plane with the landing slab; With the outside plate is the topside segmentation of basal plane, other plate segment; With the deck is the little deck panel of basal plane; And other segmentation that can use the column support type moulding bed.The present invention has overcome deficiency of the prior art, and it has improved the service life of column support type moulding bed pedestal, has increased the rigidity of moulding bed, has solved the problem that pillar freely rotates.Because it is simple in structure easy to use, get up to work efficient height and labour intensity of operating personnel's construction is low; Can save a large amount of auxiliary material, wlding and artificial for factory.Adopt moulding bed of the present invention to carry out segmentation and produce the supply and marketing that has reduction enterprise manufacturing cost, improves plant produced efficient in batches.In addition, low, the easy maintenance of maintenance cost of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing and the specific embodiment the present invention is done and to describe in further detail.

As shown in Figure 2, pillar is welded by two inside and outside footpaths of steel pipe are continuous.As Fig. 4 and shown in Figure 5, on pillar 4, set up the pillar eye plate 5 of four mutual vertical symmetry, pillar eye plate 5 can cylinder lever connecting rod, per four pillar tires are one group, the pull bar all around interconnects the pillar eye plate 5 on a plurality of pillar moulding beds of the present invention, make whole column support type moulding bed form a rigid body, satisfy production rigidity needs.Pull bar is middle band inner thread sleeve, and two ends are two equidirectional externally threaded screw rods, and screw rod can be connected with bolt with the pillar eye plate.

As shown in Figure 4, in the present embodiment, a cover spiral chieftain 6 is set on the pillar top.As shown in Figure 6, when rotating screw chieftain 6 highly finely tunes, be easy to twist on the ground; On spiral chieftain end thread groove, bead 7 is set for this reason.Install on the pillar top, before every cover spiral, earlier the chieftain is screwed to the end, and the bead 7 of burn-oning on spiral chieftain end thread groove then should overlap spiral chieftain dress at last and be welded on the pillar.

As shown in Figure 1, pedestal is made up of seat pipe 1 and interior pipe 2, and the bracket 3 that the pedestal end opening is symmetrical arranged the perforate of four bands is convenient to hand and is pulled (pulling) cucurbit and fix.Consider that factory building is an open type, the rainy day has rainwater to enter actual conditions easily, leaves the 25mm gap in ground when the moulding bed pedestal links to each other with the bracket 3 of support, to guarantee being difficult for ponding in the moulding bed pedestal.Simultaneously, if accumulation rubbish can in time be removed from the moulding bed base bottom in the pedestal.It can guarantee effectively that column support type moulding bed pedestal paint is not damaged, and prolongs pedestal service life.

As shown in Figure 3, be mutually 90 degree through holes 2 of downward 100mm place, column support type moulding bed pedestal top increases, the aperture is 30mm; Tack with latch then, each the row and each be listed as adjacent two latches be mutually 90 the degree, control moulding bed about, all around free degree; By being mutually 90 degree latch control rotary freedoms.Thereby it guarantees column support type moulding bed integral rigidity intensity effectively.

In manufacturing process, consideration moulding bed height is determined the pillar height, on original pillar 800mm basis, sets up 1200mm, 1600mm, 2400mm pillar.The column support type moulding bed is generalized to big slope even moulding bed that diclinic is cut from the less moulding bed of original flat-tyre frame, slope.
