Abstract
The utility model discloses a steel plate fixture, including screw rod, elasticity nut, trip, the screw rod both ends are connected with the elasticity nut through the screw thread respectively, are equipped with the connecting plate on the elasticity nut, and the connecting plate passes through coupling nut and is connected with the trip, ni -based steel sheet of solution low temperature that can be fine and 180 upsets of the goods hoist and mount problem when upright assembling is to the fish tail and magnetization problem on steel sheet surface when having overcome the hoist and mount of the ni -based steel sheet of low temperature.
Description
Technical field
The utility model relates to clamp art, is specifically related to a kind of steel plate fixture.
Background technology
Along with vigorously promoting the use of clean energy resource LNG, country builds LNG acception station and LNG carrier in a large number in each department, LNG storage tank many employing 9%Ni steel construction in acception station and carrier.9%Ni steel not only has good low-temperature flexibility, and under-198 DEG C of low temperature, impact toughness value can reach more than 80J; And its tensile strength lower limit is also higher, is 690MPa, it is the preferred material of building Large LNG storage tank.
In the course of processing, inevitably need to carry out 180 ° of upsets to steel plate; The shell ring of steel storage tank when assembling also needs steel plate uprightly to lift by crane.But because material is higher containing Ni, easy magnetization, surperficial matter is soft, traditional turnover fixture, as folder hook and electromagnet etc. all cannot use.Folder hooks and easily causes injurious surface mark, forms notch effect, increases the probability of material brittle failure at low ambient temperatures; Electromagnet easily causes 9%Ni steel plate to magnetize, and increases magnetic blow during Plate Welding, causes weld defect.
The development of new chemical materials has also expedited the emergence of the transport of a lot of cryogenic media in addition, and as LEG etc., its storage tank adopts 5%Ni steel making, and this steel and 9%Ni all belong to low-temperature nickel-based steel, have similar physical property.
Summary of the invention
The technical problems to be solved in the utility model is, in view of the foregoing defects the prior art has, provide a kind of steel plate fixture, can solve lifting problem when 180 ° of upsets of low-temperature nickel-based steel plate and goods thereof and upright assembling, to the scuffing of surface of steel plate and magnetization problem when overcoming low-temperature nickel-based hoisting steel plate.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
A kind of steel plate fixture, comprise screw rod, tightening nut, snap fit, described screw rod two ends are connected with tightening nut respectively by screw thread, and tightening nut is provided with connecting panel, and connecting panel is connected with snap fit by coupling nut, and snap fit opening inwards.
By such scheme, described connecting panel quantity has four, is arranged in uniformly on tightening nut cylindrical.
By such scheme, described tightening nut quantity is two, and the snap fit quantity be connected with tightening nut is 2.
By such scheme, any one snap fit described is provided with suspension ring.
By such scheme, described snap fit is provided with suspension ring.
The utility model has following beneficial effect:
Steel plate fixture described in the utility model, can solve lifting problem when 180 ° of upsets of low-temperature nickel-based steel plate and goods thereof and upright assembling, structure is simple, easy to assembly, strong operability, steel plate is positioned between the first snap fit and the second snap fit, rigid clamping is not had between steel plate and the first snap fit, the second snap fit, so surface of steel plate can not deformation in compression, also can not occur scar due to clamping surface, pure mechanical mechanism also can not make steel plate magnetize; Energy Reusability, carries out zinc-plated process by effects on surface, can apply the lifting to corrosion-resistant steel and goods thereof.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of steel plate fixture of the utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the schematic diagram that the utility model makes steel plate 180 ° and overturns;
In figure, 1-screw rod, 2-tightening nut, 3-coupling nut, 4-first snap fit, 5-second snap fit, 6-connecting panel.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
With reference to shown in Fig. 1 ~ Fig. 3, steel plate fixture described in the utility model, comprise screw rod 1, tightening nut 2, first snap fit 4, second snap fit 5, described screw rod 1 two ends are connected with tightening nut 2 respectively by screw thread, tightening nut 2 is provided with connecting panel 6, the connecting panel 6 of screw rod 1 left end is connected with the second snap fit 5 by coupling nut 3, and the connecting panel 6 of screw rod 1 right-hand member is connected with the first snap fit 4 by coupling nut 3, and the first snap fit 4 and the second snap fit 5 opening are inwards; Steel plate is positioned between the first snap fit and the second snap fit, does not have rigid clamping between steel plate and the first snap fit, the second snap fit, so surface of steel plate by compressing force deformation, also can not can not occur scar due to clamping surface of steel plate.
Connecting panel 6 quantity is four, is arranged in uniformly on tightening nut 2 cylindrical.
Tightening nut 2 quantity is two.
Second snap fit 5 is provided with suspension ring.
As shown in Figure 3, the principle of work that the utility model makes steel plate 180 ° overturn, steel plate fixture described in the utility model need two covers together with the use of, its algorithm is as follows:
1) steel plate is placed on ground or operation platform, is placed on steel plate by screw rod 1;
2) according to the tightening nut 2 at the width adjusting two ends of steel plate, any 1 of being provided with by tightening nut 2 in four connecting panels 6 is adjusted to below;
3) the first snap fit 4 and the second snap fit 5 are fixed with connecting panel 6 respectively by coupling nut 3, the second snap fit 5 should be placed on the top after lifting;
4) suspension hook of crane is passed the suspension ring on the second snap fit 5, slowly lift by crane, carry out 180 ° of upsets, as shown in Figure 2;
5), after realizing 180 ° of upsets of steel plate, coupling nut 3 is unclamped, rises and open the first snap fit 4 and the second snap fit 5, tightening nut is unclamped, screw rod 1 can be taken out;
6) lift other steel plates, repeat above step.
Above is only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalence change that the utility model claim is done, still belongs to protection domain of the present utility model.
