Description

Technical Field

[0001] The utility model relates to a tool structure, in particular to a lifting tool for an installation platform of an LNG liquid cargo ship. Background Art

[0002] As major domestic shipyards break through the technical barriers of LNG tankers, the number of orders for the construction of LNG tankers is increasing. As the installation platform of the construction platform in the tank, the workload of erection and hoisting is extremely huge. The installation platform of a tank is 50 meters long, 40 meters wide and 30 meters high. Although the entire platform can be divided into several small modules for assembly, the largest one weighs hundreds of tons. In order to ensure that such a large structure does not deform during the hoisting process, special hoisting tools are required. At present, there are not many types of special hoisting tools in China, but there are mainly the following three problems:.

[0003] The tooling is heavy. As a manually operated tooling, the heavier it is, the more physical effort the worker needs to expend, and even the assistance of a crane is needed to complete the installation operation, resulting in a waste of resources;

[0004] The operation of the tooling is complicated. The tooling needs to be fixed with bolts and nuts, which wastes time and is inefficient;

[0005] 3) The tooling is easily damaged. The positioning bolts of the tooling are easy to bend and deform, and the fixing nuts are easy to lose, which affects the service life. Therefore, a new type of lifting tooling that can solve the above problems is needed.

[0006] Therefore, a method or device capable of solving the above problems is now needed. Summary of the invention

[0007] The utility model aims to solve the above-mentioned deficiencies in the prior art and proposes a lifting tool for an installation platform of an LNG liquid cargo ship which has the advantages of simple structure, ingenious design, reasonable layout, convenient operation, safety and reliability.

[0008] The technical solution of the utility model is: a lifting tool for the installation platform of an LNG liquid cargo ship, characterized in that: the lifting tool comprises a tool body 1, and the tool body 1 is composed of an X-axis beam 2 and a Y-axis beam 3 connected to each other,

[0009] The end of the X-axis beam 2 is provided with a limit block 4 distributed along the Y-axis direction, and the bottom end surface of the limit block 4 is provided with a first arc-shaped limit surface 5. At the same time, the end of the X-axis beam 2 is also rotatably supported by a rotating shaft 6, and the two ends of the rotating shaft 6 are respectively provided with hook bodies 7.

[0010] The bottom end surfaces of both ends of the Y-axis beam 3 are provided with second arc-shaped limiting surfaces 8.

[0011] A lifting lug 9 is provided at the center of the tool body 1 .

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] This type of LNG cargo ship installation platform lifting fixture has a simple structure, ingenious design, and reasonable layout. It is designed to solve various problems existing in the working process of traditional lifting equipment. A special structure is designed. Its main part is a cross structure. The end of the cross structure is provided with a positioning arc surface that matches the beam of the structural member. At the same time, two pairs of hooks are provided on it, which can realize the rapid connection between the structural member and the fixture, so as to lift the structural member. This lifting fixture has many advantages such as light weight, easy operation, safety and reliability. At the same time, its manufacturing process is simple and the manufacturing cost is low. Therefore, it can be said that it has many advantages and is particularly suitable for promotion and application in this field. Its market prospects are very broad. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The specific implementation of the present utility model will be described below in conjunction with the accompanying drawings. Figures 1 to 4 As shown: A LNG liquid cargo ship installation platform lifting tool, which includes a tool body 1, the tool body 1 is composed of an X-axis beam 2 and a Y-axis beam 3 connected to each other,

[0019] The end of the X-axis beam 2 is provided with a limit block 4 distributed along the Y-axis direction, and the bottom end surface of the limit block 4 is provided with a first arc-shaped limit surface 5. At the same time, the end of the X-axis beam 2 is also rotatably supported by a rotating shaft 6, and the two ends of the rotating shaft 6 are respectively provided with hook bodies 7.

[0020] The bottom end surfaces of both ends of the Y-axis beam 3 are provided with second arc-shaped limiting surfaces 8.

[0021] A lifting lug 9 is provided at the center of the tool body 1 .

[0022] The working process of the LNG tanker installation platform lifting tooling of the embodiment of the utility model is as follows: the hook on the lifting device is connected to the lifting lug 9, the tooling is lifted by the lifting device, and the tooling is transported to the top of the structural member 10 that needs to be lifted, and the structural member 10 is in a frame shape as a whole.

[0023] After the tooling body 1 is adjusted to a suitable position, its first arc-shaped limiting surface 5 contacts the inner side and upper part of the beam distributed along the Y axis on the structural member 10, and the second arc-shaped limiting surface 8 contacts the inner side and upper part of the beam distributed along the X axis on the structural member 10. At this time, the tooling body 1 is pressed on the structural member 10; then the operator manually pulls the hook body 7 to change the hook body 7 from the non-connected state to the connected state (such as Figure 1 As shown), in the connected state, the hook body 7 is hooked on the bottom of the beam distributed along the Y-axis direction on the structural member 10, and the hook body 7 and the limit block 4 together lock the beam distributed along the Y-axis direction of the structural member 10, at which time the tooling body 1 and the structural member 10 are connected;

[0024] When lifting with a sling, the tooling will drive the structural member 10 to move along with the sling; after the structural member 10 is transported to the right place, the structural member 10 is lowered onto the supporting structure, at which time the structural member 10 is supported by the supporting structure, and then the hook body 7 is swung in the opposite direction to change it from a connected state to a disconnected state. At this time, the tooling is separated from the structural member 10, and the tooling is lifted to the next structural member 10 by the sling for the next lifting operation.
