Description

Technical Field

[0001] This utility model relates to the field of steel structure construction technology, and in particular to a steel structure factory assembly and lifting device. Background Technology

[0002] After the steel columns are constructed, the main steel beams and steel purlins are lifted and assembled in the steel structure workshop. Steel purlins, as small beams placed between roof trusses, gable walls, or between roof trusses and gable walls in steel structure buildings, are used to support rafters or roof panels. Their number far exceeds that of the main steel beams, and they are mainly divided into C-shaped steel and Z-shaped steel, etc.

[0003] Patent CN117231012A discloses a steel structure purlin installation device, and patent CN212893454U discloses a hoisting device for improving the hoisting efficiency of C-shaped steel purlins; both can lift and assemble multiple steel purlins in a single operation. The latter is used in conjunction with a crane. To ensure stability during lifting, the steel purlins need to be placed on both sides of the main wire rope to ensure the main wire rope is under stable stress. However, this makes it very inconvenient to retrieve the steel purlins at height. Specifically, when installing purlins on the side of a steel structure factory building, the hoisting device is located outside the building, making it difficult to remove the purlins on the outside of the main wire rope; when installing purlins on the roof of the factory building, the hoisting device also needs to be repeatedly moved to retrieve the purlins on both sides of the main wire rope.

[0007] Furthermore, the support is a rectangular ring structure with a notch, the notch being located at one corner of the upper part of the rectangular ring structure.

[0008] Furthermore, both ends of the shelf are connected to elastic ropes, and the ends of the elastic ropes are connected to hooks that limit the ends of the steel purlins.

[0009] Furthermore, a second steel wire rope is connected to the lower side of the bottom shelf, and a magnetic base is connected to the lower end of the second steel wire rope.

[0010] Furthermore, a third steel wire rope connects the lifting ring to the uppermost shelf.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The shelf of this utility model includes several support bodies with notches for steel purlins to enter and exit. A first steel wire rope is connected to the center of gravity of the support body, which can ensure that the first steel wire rope maintains vertical force balance and provides conditions for the same-side loading and unloading of steel purlins. It reduces construction difficulty, improves construction efficiency, and is safe and reliable. Moreover, this device is suitable for lifting and assembling various types of steel purlins such as C-shaped and Z-shaped. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] Specific embodiments of the steel structure factory building assembly and lifting device provided by this utility model:

[0022] Please see Figure 1-6 The steel structure workshop assembly and lifting device includes several vertically corresponding shelves 1 with supporting steel purlins 9, several first steel wire ropes 2 connecting adjacent shelves 1, and lifting rings 3 connected to the uppermost shelf 1.

[0023] The first wire rope 2 is connected to the upper and lower sides of the middle of the cross-section of the shelf 1, corresponding to the center of gravity of the shelf 1. During the lifting and hoisting process, it can keep several first wire ropes 2 in a vertically balanced state.

[0024] The shelf 1 includes several supports 101, each support 101 being a ring structure with a notch, and several crossbars 102 connecting adjacent supports 101; in this embodiment, three crossbars 102 are connected between adjacent supports 101. A first steel wire rope 2 is connected to the upper or lower middle side of the support 101.

[0025] In this embodiment, each shelf 1 includes three supports 101, and three first steel wire ropes 2 are connected between adjacent shelves 1.

[0026] Two third steel wire ropes 8 connect the lifting ring 3 to the uppermost shelf 1. In the lifting state, the lifting ring 3 corresponds to the middle of the shelf 1, and the lower ends of the two third steel wire ropes 8 are respectively connected to the two support bodies 101 at both ends of the uppermost shelf 1.

[0027] In this embodiment, the support 101 is a rectangular ring structure with a notch, located at one corner of the upper part of the rectangular ring structure. The support 101 is similar to the C-type lifting device structure in the prior art, except that the lower end has an upward bend to prevent the steel purlin 9 from falling off.

[0028] The notches of each support 101 in shelf 1 correspond. All notches in this device are located on the same side as the first wire rope 2, which facilitates the removal and placement of steel purlins 9 on the same side of the device. When constructing on the side of the factory building, the notches are oriented towards the factory building for easy access by workers.

[0029] When taking or placing the steel purlin 9, it is allowed to pass horizontally through the notch and enter or exit the shelf 1; when the steel purlin 9 is placed on the lower inner side of the shelf 1, the lower part of the support body 101 limits the steel purlin 9 on both sides.

[0030] To prevent the steel purlin 9 from slipping off at both ends, in some other embodiments, a rubber pad layer can be provided on the inner side of the support body 101 to contact the steel purlin 9, increasing friction and reducing the risk of slippage. In this embodiment, elastic ropes 4 are connected to both ends of the shelf 1, and the elastic ropes 4 are connected to the support body 101. The ends of the elastic ropes 4 are connected to hooks 5 that limit the ends of the steel purlin 9. In some embodiments, by adjusting the size of the support body 101 and the hooks 5, the shelf 1 is not limited to carrying and supporting only one steel purlin 9.

[0031] After the steel purlin 9 is placed into the shelf 1, the hook 5 is hooked onto the end of the steel purlin 9 by stretching the elastic rope 4, which can prevent the steel purlin 9 from slipping off the end of the shelf 1 due to shaking during the lifting process.

[0032] During assembly, workers need to remove and assemble the steel purlins 9 one by one, and at least pre-fix them with bolts, which takes a certain amount of time. To prevent the device from shaking significantly due to wind or other external factors during this process, and to protect the safety of workers and the installed steel structure, in this embodiment, the lowermost shelf 1 has a second steel wire rope 6 connected to both ends of its lower side. The second steel wire rope 6 is connected to the support body 101, and the lower end of each second steel wire rope 6 is connected to a magnetic base 7.

[0033] When working on the top and sides of the factory building, workers can open the magnetic base 7 to magnetically attach it firmly to the steel column or main steel beam. The crane tensions all the wire ropes, limiting the large-scale swaying of the device and ensuring that workers can safely retrieve the assembled steel purlins 9 one by one.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
