Description

Technical Field

[0001] This utility model relates to the field of steel structure hoisting technology, specifically to a hoisting mechanism for lifting multiple I-beams. Background Technology

[0002] I-beams are commonly used as a material in steel structure buildings or the construction industry. I-beams have good bending resistance and load-bearing capacity. During use, I-beams are cut into sections of different lengths. Due to their heavy weight, multiple I-beams are usually hoisted in batches to improve hoisting efficiency. Generally, multiple I-beams are tied together with lifting ropes (steel wire ropes) before being hoisted by lifting equipment. During hoisting, it is not always possible to ensure that the center of gravity of the I-beam is completely in the center of the lifting rope. Furthermore, because of the shape of the I-beams, there are large gaps between them. Therefore, the tied I-beams are prone to tilting during hoisting, which leads to the risk of falling during transportation. A fall can easily cause a serious safety accident. Utility Model Content

[0003] The purpose of this invention is to provide a lifting mechanism for hoisting multiple I-beams, which reduces the risk of the I-beams falling during hoisting and avoids safety accidents.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0005] A lifting mechanism for hoisting multiple I-beams includes a first lifting rope and a second lifting rope for binding the multiple I-beams. The first and second lifting ropes are arranged in a triangular shape. The top ends of the first and second lifting ropes are connected to the hooks of the lifting equipment. The outer sides of the first and second lifting ropes are respectively provided with a first protective sleeve and a second protective sleeve fitted onto the ends of the multiple I-beams. The first protective sleeve is detachably connected to the first lifting rope, and the second protective sleeve is detachably connected to the second lifting rope. An elastic connector is provided between the first and second protective sleeves on the bottom surface of the multiple I-beams. The two ends of the elastic connector are detachably connected to the first and second protective sleeves, respectively.

[0006] In this design, the first and second lifting ropes are arranged in a triangular pattern, a standard arrangement for lifting I-beams. This arrangement utilizes the stability principle of a triangle, ensuring good stability even under external forces or vibrations during lifting, reducing the risk of the I-beam swaying or falling. The triangular arrangement also effectively distributes the force of gravity during lifting, reducing the load on individual ropes and extending their service life. The tops of both ropes are directly connected to the hook of the lifting equipment, ensuring directness and efficiency in lifting. This connection method is simple and quick, facilitating installation and disassembly by operators. Before lifting, a first protective sleeve and a second protective sleeve are respectively placed on both ends of the bundled I-beam. The first protective sleeve is detachably connected to the first lifting rope, and the second protective sleeve is detachably connected to the second lifting rope. After the two protective sleeves are connected to their corresponding lifting ropes, the I-beam is lifted to a distance of several tens of centimeters to one meter off the ground. Then, the two ends of the elastic connector are connected to the two protective sleeves respectively, connecting the two protective sleeves into a whole. In this way, even if the I-beam tilts during the lifting process, the first or second protective sleeves on both sides can act as a stop and limit the movement of the I-beam, thereby reducing the risk of the I-beam falling and avoiding safety accidents.

[0007] Optionally, both the first and second protective sleeves are mesh-shaped flexible sleeves, with one end open and the other end closed, allowing multiple I-beams to pass through.

[0008] Optionally, the flexible sleeve is a mesh made of steel wire or nylon, and the mesh on the flexible sleeve does not allow a single I-beam to pass through.

[0009] Optionally, both the first protective sleeve and the second protective sleeve are provided with buckles at their upper ends. The buckle on the first protective sleeve is detachably connected to the first hoisting rope, and the buckle on the second protective sleeve is detachably connected to the second hoisting rope.

[0010] Optionally, both the first protective sleeve and the second protective sleeve are provided with a first rubber rope for connecting the buckle at the upper end.

[0011] Optionally, the elastic connector is a second rubber rope, with both ends of the second rubber rope being detachably connected to the lower ends of the mesh-like first protective sleeve and the second protective sleeve, respectively.

[0012] Optionally, the length of the second rubber rope is less than the distance between the open end faces of the first protective sleeve and the second protective sleeve.

[0013] Optionally, the second rubber rope is connected to hooks at both ends, and the lower ends of the first and second protective sleeves are provided with connecting rings for connecting to the hooks.

[0014] Optionally, the first and second lifting ropes are steel wire ropes.

[0015] The beneficial effects of this utility model are:

[0016] 1. In this utility model, a first protective sleeve and a second protective sleeve are respectively fitted onto both ends of the bundled I-beam. The first protective sleeve is detachably connected to the first lifting rope, and the second protective sleeve is detachably connected to the second lifting rope. After the two protective sleeves are connected to their corresponding lifting ropes, the I-beam is lifted to a distance of several tens of centimeters to one meter off the ground. Then, the two ends of the elastic connector are respectively connected to the two protective sleeves, connecting the two protective sleeves into a whole. In this way, even if the I-beam tilts during the hoisting process, the first or second protective sleeves on both sides can play a role in blocking and limiting the I-beam, thereby reducing the risk of the I-beam falling and avoiding the occurrence of safety accidents.

[0023] Example

[0024] A lifting mechanism for hoisting multiple I-beams includes a first lifting rope 1 and a second lifting rope 2 for binding multiple I-beams 10. The first lifting rope 1 and the second lifting rope 2 are arranged in a triangular shape. The top ends of the first lifting rope 1 and the second lifting rope 2 are connected to the hook of the lifting equipment. The outer sides of the first lifting rope 1 and the second lifting rope 2 are respectively provided with a first protective sleeve 3 and a second protective sleeve 4, which are sleeved on the ends of the multiple I-beams 10. The first protective sleeve 3 is detachably connected to the first lifting rope 1, and the second protective sleeve 4 is detachably connected to the second lifting rope 2. An elastic connector is provided between the first protective sleeve 3 and the second protective sleeve 4 on the bottom surface of the multiple I-beams 10. The two ends of the elastic connector are detachably connected to the first protective sleeve 3 and the second protective sleeve 4, respectively.

[0025] In this embodiment, as Figure 1As shown, both the first lifting rope 1 and the second lifting rope 2 are dedicated steel wire ropes for hoisting. Both ropes are of the same length. Existing steel wire ropes have loops at both ends; the upper loop is used to connect to the hook of the lifting equipment, and the lower loop is typically used to bind multiple I-beams 10 via U-shaped buckles. The structure and binding method of the lifting ropes are existing technology. The first lifting rope 1 and the second lifting rope 2 are arranged in a triangular shape, which is a conventional arrangement for hoisting I-beams 10. This arrangement utilizes the stability principle of a triangle, ensuring good stability even when encountering external forces or vibrations during hoisting, reducing the risk of the I-beams 10 swaying or falling off. The triangular arrangement also effectively distributes the force of gravity during hoisting, reducing the load on individual ropes and extending their service life. The tops of the first lifting rope 1 and the second lifting rope 2 are directly connected to the hook of the lifting equipment, ensuring directness and efficiency in hoisting. This connection method is simple and quick, facilitating installation and disassembly by operators. Before lifting, first protective sleeve 3 and second protective sleeve 4 are respectively placed on both ends of the bundled I-beam 10. The first protective sleeve 3 is detachably connected to the first lifting rope 1, and the second protective sleeve 4 is detachably connected to the second lifting rope 2. After the two protective sleeves are connected to the corresponding lifting ropes, the I-beam 10 is lifted to a distance of several tens of centimeters to one meter off the ground to leave space for the installation of the elastic connector. Then, the two ends of the elastic connector are connected to the two protective sleeves respectively, connecting the two protective sleeves into a whole. In this way, during the lifting of the I-beam 10, no matter which direction the I-beam 10 tilts, the first protective sleeve 3 or the second protective sleeve 4 can act as a blocking and limiting function for the I-beam 10, thereby reducing the risk of the I-beam 10 falling and avoiding the occurrence of safety accidents.

[0026] Furthermore, both the first protective sleeve 3 and the second protective sleeve 4 are mesh-shaped flexible sleeves, with one end open and the other end closed, allowing multiple I-beams 10 to pass through.

[0027] Specifically, both protective sleeves are flexible mesh sleeves. The mesh design reduces the weight of the protective sleeves and makes them easier to handle and move. The flexible sleeves are used to make it easier to put the protective sleeves on the I-beam 10. The size of the opening end of the flexible sleeve needs to be larger than the size of the end of the bundled I-beam 10 so that the two protective sleeves can be put on both ends of the bundled I-beam 10.

[0028] Furthermore, the flexible sleeve is a mesh made of steel wire or nylon, and the mesh on the flexible sleeve does not allow a single I-beam 10 to pass through.

[0029] Specifically, the flexible sleeve is made of steel wire or nylon rope. Both steel wire and nylon are high-strength and wear-resistant materials, which can extend the service life of the protective sleeve. The mesh on the protective sleeve does not allow a single H-beam 10 to pass through, so when an inclined H-beam 10 acts on the protective sleeve, it will not fall out of the mesh. The protective sleeve provides better protection, making it less likely for the H-beam 10 to fall during hoisting.

[0030] Furthermore, both the first protective sleeve 3 and the second protective sleeve 4 are provided with a buckle 6 at their upper ends. The buckle 6 on the first protective sleeve 3 is detachably connected to the first suspension rope 1, and the buckle 6 on the second protective sleeve 4 is detachably connected to the second suspension rope 2.

[0031] Specifically, the locking buckle 6 in this solution is a mountaineering locking buckle 6. This type of locking buckle 6 is commercially available, simple to operate, and easy to install and disassemble. After the first protective sleeve 3 and the second protective sleeve 4 are completely fitted onto both ends of the I-beam 10, the locking buckle 6 can more conveniently and efficiently connect with the first suspension rope 1 and the second suspension rope 2, so that the first protective sleeve 3 is connected to the first suspension rope 1 as one unit, and the second protective sleeve 4 is connected to the second suspension rope 2 as one unit. The connection of the locking buckle 6 makes it difficult for the protective sleeve to detach from the suspension rope when it is subjected to pressure from the I-beam 10.

[0032] Furthermore, the upper ends of both the first protective sleeve 3 and the second protective sleeve 4 are provided with a first rubber rope 5 for connecting the buckle 6.

[0033] Specifically, the buckle 6 is connected to the protective sleeve via the first rubber rope 5. The first rubber rope 5 is elastic. When the buckle 6 is connected to the corresponding suspension rope, and one end of the I-beam 10, which has a tendency to slip, acts on the protective sleeve, the first rubber rope 5 will generate a rebound force towards the middle of the I-beam 10 when it is compressed. This makes the protective sleeve better at limiting the I-beam 10.

[0034] like Figure 2 As shown, further, the elastic connector is a second rubber rope 9, and the two ends of the second rubber rope 9 are detachably connected to the lower ends of the mesh-shaped first protective sleeve 3 and the second protective sleeve 4, respectively.

[0035] Specifically, the second rubber rope 9 connects the lower ends of the first protective sleeve 3 and the second protective sleeve 4, which can prevent the first protective sleeve 3 and the second protective sleeve 4 from slipping off the I-beam 10.

[0036] Furthermore, the length of the second rubber rope 9 is less than the distance between the open end faces of the first protective sleeve 3 and the second protective sleeve 4.

[0037] Specifically, after the first protective sleeve 3 and the second protective sleeve 4 are installed at both ends of the I-beam 10, the distance between their open end faces is greater than the length of the second rubber rope 9. In this way, when the second rubber rope 9 is connected to the lower end of the two protective sleeves, it is in a stretched state. The rebound force generated by the second rubber rope 9 itself can further secure the two protective sleeves to both ends of the bound I-beam 10, so that the I-beam 10, which has a tendency to slip, will not detach from the protective sleeve on either side, thus avoiding the risk of the I-beam 10 falling.

[0038] Furthermore, the second rubber rope 9 is connected to hooks 8 at both ends, and the lower ends of the first protective sleeve 3 and the second protective sleeve 4 are provided with connecting rings 7 for connecting to the hooks 8.

[0039] Specifically, in order to facilitate the quick installation of the second rubber rope 9, hooks 8 are fixed at both ends of the second rubber rope 9. During installation, the hooks 8 can be directly hooked onto the connecting rings 7, which is convenient and quick, and makes disassembly easier later.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
