Description

Technical Field

[0001] The utility model relates to the technical field of lifting tooling, in particular to a tool for lifting prefabricated beams and slabs on a dock. Background Art

[0002] Beam-slab beams are structural members made of steel plates. Their basic cross-section is an I-beam, with upper and lower horizontal plates called flanges and the middle vertical plate called the web. Some plate beams have several reinforcing ribs welded to the center. Depending on the assembly method, they can be categorized as welded plate beams, high-strength bolted plate beams, and heterogeneous steel plate beams.

[0003] With the rapid development of society, beams and slabs are becoming more and more like precast beams and slabs. During the transportation of precast beams and slabs, they are transported over long distances through docks and need to be lifted from the docks to the target ship hull. However, the existing precast beam and slab lifting methods are complicated during lifting. After lifting to the target location, they need to be disassembled again, which increases manpower consumption to a certain extent and is inefficient.

[0004] Therefore, a tool for hoisting prefabricated beams and slabs at a wharf is proposed. Utility Model Content

[0005] In view of this, the embodiments of the present invention hope to provide a tool for lifting prefabricated beams and slabs at a dock to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0007] A hanging plate for carrying the precast beam slab during lifting, the hanging plate being provided with a plurality of grooves, and an L-shaped plate being hingedly connected to the interior of each groove, the L-shaped plate having a limiting portion for limiting the position of the precast beam slab, and the limiting portion being provided with a through hole for the lifting rope to pass through;

[0008] A bottom plate, wherein a plurality of lifting blocks are fixedly connected to the bottom plate;

[0009] in:

[0010] When the hanging plate falls on the bottom plate, the top of the lifting block contacts the bottom of the L-shaped plate, and the L-shaped plate rotates 90 degrees.

[0011] In some embodiments, two limiting rods are fixedly connected to the hanging plate.

[0012] In some embodiments, the L-shaped plate further has a lifting portion that contacts the lifting block.

[0013] In some embodiments, a roller is installed on one side of the lifting portion.

[0014] In some embodiments, a limiting plate is fixedly connected to the inner side of the groove, and the upper surface of the limiting plate is attached to the bottom of the L-shaped plate.

[0015] In some embodiments: the hanging plate is evenly provided with first through grooves.

[0016] In some embodiments, second through grooves are evenly distributed on the bottom plate.

[0017] In some embodiments, a positioning plate is fixedly connected to a corner of one side of the bottom plate.

[0018] The embodiment of the present invention has the following advantages due to the adoption of the above technical solution:

[0019] 1. The utility model places the prefabricated beam plate on the hanging plate, then the lifting rope of the lifting device passes through the through hole of the L-shaped plate, and the lifting device lifts the hanging plate upward. Under the action of the pulling force, the limiting part of the L-shaped plate is pressed against the prefabricated beam plate, completing the fixation of the prefabricated beam plate.

[0032] The embodiments of the utility model will be described in detail below in combination with the drawings.

[0033] As Figure 1-5 shown, the utility model embodiment provides a wharf prefabricated beam plate hoisting tool, including:

[0034] A hanging plate 1 is used to support the precast beam slab during lifting. The hanging plate 1 is provided with a plurality of grooves 11, and an L-shaped plate 12 is hingedly connected to the interior of each groove 11. The L-shaped plate 12 has a limiting portion 122 for limiting the position of the precast beam slab, and the limiting portion 122 is provided with a through hole 121 for the lifting rope to pass through;

[0035] A bottom plate 2, to which a plurality of lifting blocks 21 are fixedly connected;

[0036] in:

[0037] When the hanging plate 1 falls on the bottom plate 2, the top of the lifting block 21 contacts the bottom of the L-shaped plate 12, and the L-shaped plate 12 rotates 90 degrees.

[0038] In this embodiment, specifically: two limit rods 13 are fixedly connected to the hanging plate 1, and the two limit rods 13 are used to limit the position of the precast beam plate on the hanging plate 1;

[0039] More specifically, Figure 1 As shown, the two limiting rods 13 can be eliminated, and grooves 11 can be provided on the hanging plate 1 at positions corresponding to the two limiting rods 13, and an L-shaped plate 12 can be provided therein.

[0040] On the basis of the above solution, in order to further improve the fixing effect, an elastic member can be added to the limit portion 122 of the L-shaped plate 12 to provide an elastic fixing effect on the prefabricated beam plate on the hanging plate 1.

[0041] In this embodiment, specifically: the L-shaped plate 12 also has a lifting portion 123 that contacts the lifting block 21. When the hanging plate 1 falls on the bottom plate 2, the lifting block 21 contacts the contact portion 125 (such as Figure 4 As shown), at this time, the L-shaped plate 12 is flipped 90°, the lifting portion 123 passes through the groove 11, and the precast beam plate is lifted. At the same time, the restriction of the position of the precast beam plate by the limiting portion 122 is cancelled, and the precast beam plate can be transported to the designated location.

[0042] In this embodiment, specifically: a roller 124 is installed on one side of the lifting part 123, and the lifting part 123 passes through the groove 11. When the precast beam is lifted, the roller 124 contacts the bottom of the precast beam at the same time, which facilitates the sliding of the precast beam. At the same time, when the lifting part 123 passes through the groove 11 to lift the precast beam, the bottom of the precast beam is higher than the height of the limit rod 13.

[0043] In this embodiment, specifically: a limiting plate 15 is fixedly connected to the inner side of the groove 11 , and the upper surface of the limiting plate 15 is attached to the bottom of the L-shaped plate 12 to limit the position and movement direction of the L-shaped plate 12 .

[0044] In the embodiment, specifically, the first through grooves 14 are evenly arranged on the hanging plate 1, and the second through grooves 23 are evenly arranged on the bottom plate 2, the first through grooves 14 and the second through grooves 23 are used for reducing the dead weight and enabling water to flow out.

[0045] In the embodiment, specifically, the positioning plate 22 is fixedly connected to one side corner of the bottom plate 2, and the positioning plate 22 is in the shape of L, so as to be aligned with the bottom plate 2 when the hanging plate 1 falls.

[0046] In the working process of the utility model, first, the prefabricated beam plate is placed on the hanging plate 1, then the lifting rope of the lifting device is passed through the through hole 121 of the L-shaped plate 12, the hanging plate 1 is lifted upward by the lifting device, under the action of the pulling force, the limiting part 122 of the L-shaped plate 12 is tightly attached to the prefabricated beam plate, and the position of the L-shaped plate 12 is limited under the action of the limiting plate 15;

[0047] When the lifting device falls, the positioning plate 22 is positioned, the jacking block 21 on the bottom plate 2 is jacked against the contact part 125 at the bottom of the jacking part 123 of the L-shaped plate 12, after the L-shaped plate 12 is rotated by 90°, the jacking block 21 and the roller 124 jacks the prefabricated beam plate, so as to facilitate the movement of the prefabricated beam plate;

[0048] Through the above steps, the fixing and dismounting of the prefabricated beam plate are completed, manual fixing and dismounting are not needed in the whole process, labor is saved, and work efficiency is improved.

[0049] The above is only a specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can easily think of various changes or replacements within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
