Abstract
Description
Technical Field
[0001] This utility model belongs to the field of prefabricated container house hoisting technology, specifically, it relates to a special hoisting tool for dismantling prefabricated container houses. Background Technology
[0002] With the rapid development of the construction industry, prefabricated modular houses have been widely used as temporary structures in construction sites, engineering sites, and emergency disaster relief due to their advantages such as convenient installation and reusability. Prefabricated modular houses typically consist of multiple modular units stacked together to form a composite structure. The corners of these units are close together, and the lifting holes for connecting hooks and ropes are usually located at the corners. This makes it difficult to install hooks and ropes on the adjacent side of two modular units during dismantling. Currently, the common practice is to move the outer modular unit outwards to create a gap between adjacent units for hook and rope installation. However, this method is not only cumbersome and time-consuming, but also prone to damaging the corners, affecting the reusability of the modular units. Utility Model Content
[0003] To solve or partially solve the problems existing in related technologies, this utility model provides a special lifting tool for dismantling prefabricated container houses. This special lifting tool for dismantling prefabricated container houses aims to solve the problems of cumbersome operation, time and labor costs, and easy damage to the corners of the container houses in the existing lifting methods for dismantling container houses, which affect the reusability of the container units.
[0004] This application provides a special lifting tool for dismantling prefabricated container houses, including a corner connecting plate, a lifting plate, and locking bolts;
[0005] The corner connecting plate includes a first connecting part and a second connecting part arranged at right angles. Bolt holes are provided on the first connecting part and the second connecting part. The bolt holes correspond one-to-one with the tapping holes at the top of the corner of the box unit. The corner connecting plate is detachably fixed to the top of the corner of the box unit by locking bolts.
[0006] The hanging plate is fixedly installed on the upper end of the corner connecting plate of the box, and the hanging plate is set perpendicular to the corner connecting plate of the box. The hanging plate has a hanging hole.
[0007] In one alternative, the first and second connecting parts of the corner connecting plate are integrally formed, and the first and second connecting parts are symmetrically arranged on both sides of the hanging plate.
[0008] In one alternative, the projections of the corner connecting plates and hanging plates in the horizontal plane are all located within the enclosure unit.
[0009] The beneficial effects of this utility model are:
[0010] This utility model, by setting corner connecting plates that match the top structure of the corners of the container unit, and installing lifting plates on the corner connecting plates for connecting crane hooks or lifting ropes, allows the crane hooks or lifting ropes to be hung on the top of the container unit to be lifted by installing one of these special lifting tools on the top of each of the four corners of the container unit to be lifted.

[0024] The existing methods for dismantling container houses involve cumbersome operations, are time-consuming and labor-intensive, and can easily damage the corners of the container, affecting the reusability of the container unit.
[0025] To address the aforementioned problems, this application proposes improvements and innovations, including the following embodiments.
[0026] In some implementations, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 A special lifting tool for dismantling prefabricated modular housing is provided, including a corner connecting plate 1, a lifting plate 2, and locking bolts 3. The corner connecting plate 1 includes a first connecting part 11 and a second connecting part 12 arranged at right angles. Bolt holes 10 are provided on the first connecting part 11 and the second connecting part 12. The bolt holes 10 correspond one-to-one with the tapping holes at the top of the corner of the modular housing unit 4. The corner connecting plate 1 is detachably fixed to the top of the corner of the modular housing unit 4 by means of locking bolts 3. The lifting plate 2 is fixedly installed on the upper end of the corner connecting plate 1 and is set perpendicular to the corner connecting plate 1. The lifting plate 2 is provided with lifting holes 20.
[0027] Specifically, the corner connecting plate 1 and the hanging plate 2 are both steel plates with a diameter of t=8mm. The first connecting part 11 and the second connecting part 12 are respectively provided with two bolt holes 10 with a diameter of 12mm. The locking bolt 3 is an M12 high-strength bolt. The hanging hole 20 on the hanging plate 2 is a vertically arranged D35×L60 waist-shaped hole.
[0028] When it is necessary to lift and dismantle the prefabricated container house, install one of these special lifting tools on the top of each of the four corners of the container unit 4 to be lifted, such as... Figure 5 , Figure 6 As shown, the four hooks or ropes of the crane pass through the lifting holes 20 on the lifting plates 2 at the four corners of the box to hook onto the lifting plates 2, so that a box unit 4 that is close to other box units 4 can be lifted directly.
[0029] Thus, this special lifting tool, by setting a corner connecting plate 1 that matches the top structure of the corner of the box unit 4, and installing a lifting plate 2 on the corner connecting plate 1 for connecting the crane hook or lifting rope, allows the crane hook or lifting rope to be hung on the top of the box unit 4 to be lifted by installing one of these special lifting tools on the top of each of the four corners of the box unit 4 to be lifted. When installing the hook and lifting rope, there is no need to move the outer box unit 4 outward to create a gap between adjacent box units 4, avoiding the problem in the prior art where it is difficult to install hooks and lifting ropes on the adjacent side of two box units 4. The installation and operation of this special lifting tool is simple, convenient, quick, time-saving and labor-saving, which can effectively improve the lifting and dismantling efficiency of prefabricated box houses, effectively avoid damage to the corners of the box unit 4, and help ensure the reusability of the box unit 4.
[0030] In some embodiments, the first connecting part 11 and the second connecting part 12 of the corner connecting plate 1 are integrally formed to ensure the structural stability of the corner connecting plate 1; the first connecting part 11 and the second connecting part 12 are symmetrically arranged on both sides of the lifting plate 2 to ensure the uniformity of the force on the box unit 4 during the hoisting process, so as to ensure the stable and safe hoisting of the box unit 4.
[0031] In some implementations, the projections of the corner connecting plate 1 and the hanging plate 2 in the horizontal plane are all located within the box unit 4. This ensures that the corner connecting plate 1 and the hanging plate 2 installed at the two corners of the two adjacent sides of the two box units 4 are not affected by the other box unit 4, thereby ensuring that the box unit 4 to be hoisted can be hoisted smoothly.
[0032] Finally, it should be noted that although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, all of which should be included within the protection scope of this application.
