A kind of Body section turn-over auxiliary tool
The present invention relates to hull frock field, particularly relate to a kind of Body section turn-over auxiliary tool.
Along with enforcing of IMO tissue " the special seawater ballast tank of boats and ships and bulge carrier two topside places protective coat performance standard " (PSPC) specification; numerous ship enterprise is for adapting to PSPC new coating specification; many by larger for division of hull with the integraty ensureing hull structure; segmentation pre outfitting also installs fittings to greatest extent; although the work capacity of region fitting-out and berth fitting-out can be reduced; reduce the breakdown of coating after segmentation application; improve ship building efficiency, but the volume and weight of segmentation also increases greatly.
For general ship enterprise, building berth lifting appliance and available stand up limited space, segmentation that ultra-wide is overweight can only be landed and be stood up, or lease Oversize vehicle hang stand up auxiliary.Segmentation is landed and is stood up due to unbalance stress, and not only hull structure easily produces distortion, but also can produce destruction to paint coating; Lease large-scale crane auxiliary body turning, time on building berth and laid down cost will be increased, the serial ship of especially batch construction.
Summary of the invention
The object of the invention is the problem solving building berth crane capacity and stand up insufficient space.
For reaching above-mentioned purpose, the invention provides a kind of Body section turn-over auxiliary tool, being made up of base, overturning rack and shaft seat, shaft seat is arranged on the axial middle of base, and overturning rack to be arranged on shaft seat and can to rotate around this shaft seat.
Above-mentioned base comprises two parallel and support portions extended longitudinally, multiple parallel to each other and diagonal angle connecting portion at two diagonal angles of rectangle being vertically set on connecting portion between these two support portions, connecting two adjacent connecting portions and encircle a city with described two support portions, this diagonal angle connecting portion is multiple, and adjacent two diagonal angle connecting portion angles in 90 °.
The two ends of above-mentioned base are respectively provided with one across the rectangle buttress on described two support portions.
Above-mentioned support portion is made up of channel-section steel, and described connecting portion and diagonal angle connecting portion are made up of angle steel.
Overturning rack is made up of the first bracket in 90 ° mutually and the second bracket, and the connecting portion of this first bracket and the second bracket is connected with shaft seat by bearing pin.
Above-mentioned first bracket and the second bracket are formed by three parallel cross bars and multiple vertical pole be vertically set between these three cross bars.
Above-mentioned first bracket and the second bracket are at least two-layer, by connecting along its transversely arranged multiple columns between levels.
The pull bar of the end connecting the column be on diagonal position is provided with between adjacent column.
The invention has the beneficial effects as follows: body section can not be caused to be out of shape because of unbalance stress when landing and standing up, or paint destroys, whole process of standing up is steady, simple, and safety is higher.
Below in conjunction with the drawings and the specific embodiments, the present invention is described in further detail.

Detailed description of the invention
In order to solve building berth crane capacity and stand up the problem of insufficient space, present embodiments provide the Body section turn-over auxiliary tool shown in a kind of Fig. 1, be made up of base 1, overturning rack 2 and shaft seat 3, shaft seat 3 is arranged on axis (the i.e. graphic horizontal direction) middle of base 1, overturning rack 2 is connected with shaft seat 3 by bearing pin 4, be made up of the first bracket 12 in 90 ° mutually and the second bracket 13 by the high-visible overturning rack of Fig. 22, the connecting portion 14 of the first bracket 12 and the second bracket 13 is connected with shaft seat 3 by bearing pin 4.
As seen from Figure 3, the first bracket 12 and the second bracket 13 are formed by three parallel cross bars 15,16,17 and multiple vertical pole 18 be vertically set between these three cross bars 15,16,17.
Be not difficult to find out by Fig. 2, first bracket 12 and the second bracket 13 are at least two-layer (can ensure the intensity of overturning rack 2), by connecting along its transversely arranged multiple columns 19 between levels, between adjacent column 19, be provided with the pull bar 20 of the end connecting the column 19 be on diagonal position.
Overturning rack 2 can be by the double-layer structure be spliced by section bars such as angle steel, is combined into two orthogonal supporting seats (the present embodiment is referred to as bracket).
The formation of base 1 as shown in Figure 5, comprise two parallel and longitudinally (i.e. graphic horizontal direction) extend support portion 6,7, multiple parallel to each other and the connecting portion 8, in fact unnecessary 2 of the 9(that are vertically set between these two support portions 6,7, only illustrate 2 connecting portions in this figure), the diagonal angle connecting portion 11 at two diagonal angles of rectangle 10 that connects adjacent two connecting portions 8,9 and encircle a city with two support portions 6,7, this diagonal angle connecting portion 11 is multiple, and adjacent two diagonal angle connecting portion 11 angles in 90 °.
From Fig. 4 or 5, the two ends of base 1 are respectively provided with one across the rectangle buttress 5 on two support portions 6,7.Support portion 6,7 is made up of channel-section steel, and connecting portion 8,9 and diagonal angle connecting portion 11 are made up of angle steel.Base 1 can be a kind of steel structure pedestal be spliced by the section bar such as channel-section steel and angle steel, and rectangle buttress 5 is steel pier, with ensure segmentation place and stand up time steady.
When building berth stands up body section, because the restriction in load-carrying ability and space, the segmentation that large-scale over-long is overweight cannot aloft be stood up with crane completely, stand up if landed, again because the problem of discontinuity, cause body section to be out of shape or rub causing paint to destroy, so use the present embodiment to provide Body section turn-over auxiliary tool coordinate loop wheel machine to complete the detailed process of standing up as follows: the hull 21(stood up first will be needed to see Fig. 7) segmental hoisting to overturning rack 2 put surely be close to, contact supporting-point is carried out paint coating protection, and do simple anti-skidding reinforcement in closing up mouth place and standing up auxiliary mould of segmentation both sides, then by hyperphoric for crane rope to standing up on hanger, operation loop wheel machine stands up, under the pressure that overturning rack 2 produces in body section weight and friction force effect, pull without the need to power, the bearing pin 4 that can rotate on axle bed 3 rotates, because there is the support of overturning rack 3 and base 1 both sides rectangle buttress 5, body section can not be caused to be out of shape because of unbalance stress when landing and standing up, or paint destroys, whole process of standing up is steady, simple, and safety is higher.
According to the method for operation of embodiment one, not only can effectively utilize building berth loop wheel machine and space to carry out standing up of large-scale overweight body section, and efficiency is higher.Stood up with use loop wheel machine in the past, land and stand up rear segmentation and easily cause distortion, later stage at substantial manpower and materials are corrected, rent large-scale crane and carry out auxiliary body turning, each expense unit at least up to ten thousand, and the Body section turn-over auxiliary tool using the present embodiment to provide coordinates loop wheel machine to complete ship hull sectional turn-over, only need 4 ~ 5 people's operation within about 1 hour, just can reach requirement, safety is also higher.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
