Abstract
Description
Technical Field
[0001] This utility model relates to the field of T-beam hoisting technology, and in particular to a T-beam hoisting screw rod. Background Technology
[0002] T-beam hoisting refers to the construction process of transporting T-shaped beam components from the ground or storage location to the predetermined installation position using lifting equipment (such as cranes, hoists, etc.). This operation is a key step in the construction of prefabricated structures in building engineering and is commonly used in bridge construction and other projects. Before hoisting, the strength of the beam and the safety of the lifting equipment must be checked. During hoisting, the lifting point, lifting speed, and beam balance must be precisely controlled to ensure smooth transportation and positioning installation. The entire process must strictly adhere to safety regulations and construction techniques to ensure project quality and operational safety.
[0003] Traditional T-beam hoisting equipment includes slings, chains, wire ropes, hooks, and clamps. However, traditional hoisting equipment has drawbacks for T-beam hoisting or requires auxiliary measures to protect the finished product during hoisting. Utility Model Content
[0004] The purpose of this utility model is to provide a T-beam hoisting screw rod to solve the problems of inconvenience in hoisting T-beams and reducing the need for additional protection of finished products or damage during hoisting.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A T-beam hoisting screw includes a first rod body and a second rod body; the first end of the first rod body and the first end of the second rod body extend into a horizontal hoisting hole at the bottom of the T-beam and are connected by threads in the hoisting hole; the second end of the first rod body and the second end of the second rod body are both connected to a lifting ring.
[0006] Furthermore, the first end of the first rod is provided with an internally threaded blind hole; the outer side of the first end of the second rod is provided with a third externally threaded section that mates with the internally threaded blind hole.
[0007] Furthermore, locking rings are provided on the outer side of the second end of the first rod and the outer side of the second end of the second rod, and the locking rings are attached to the lower side of the T-beam.
[0008] Furthermore, the locking ring moves axially.
[0009] Furthermore, the first rod body has a first external thread section on the outer side of the second end, and the second rod body has a second external thread section on the outer side of the second end; the locking ring has an internal thread through hole in the middle.
[0010] Furthermore, the first rod body has a first intermediate section in the middle, the outer diameter of the first intermediate section being larger than the outer diameter of the first external thread section; the second rod body has a second intermediate section in the middle, the outer diameter of the second intermediate section being larger than the outer diameter of the second external thread section.
[0011] Furthermore, a centering auxiliary component is fitted on the outer side of both the first and second external thread sections, and the centering auxiliary component is located on the inner side of both ends of the lifting hole.
[0012] Furthermore, the cross-sectional shape of the centering auxiliary component is C-shaped.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model employs a threaded double-rod structure inserted into the lifting hole of a T-beam to support the T-beam. A locking ring secures the structure, and lifting rings on both sides lift it, preventing instability of the center of gravity during lifting and thus preventing the beam from tilting. Simultaneously, the threaded rod has a certain length, reducing impact on the beam's edges by the lifting equipment, thus playing a positive role in lifting safety and protecting the finished product. A centering auxiliary component allows for quick centering, ensuring balance and safety during lifting. Attached Figure Description

[0021] 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.
[0022] Specific embodiment 1 of the T-beam hoisting screw provided by this utility model: Please see Figure 1-4 The T-beam hoisting screw includes a first rod 1 and a second rod 2; the raw material for both the first rod 1 and the second rod 2 is galvanized round steel.
[0023] The first end of the first rod 1 and the first end of the second rod 2 extend into the horizontal lifting hole at the bottom of the T-beam and are connected by threads within the lifting hole. Specifically, the first end of the first rod 1 is provided with an internally threaded blind hole 13; the outer side of the first end of the second rod 2 is provided with a third externally threaded section 23 that mates with the internally threaded blind hole 13; the third externally threaded section 23 rotates into the internally threaded blind hole 13 to achieve the threaded connection between the first rod 1 and the second rod 2.
[0024] The length of the internal thread blind hole 13 is the same as the length of the third external thread section 23. The third external thread section 23 can be fully inserted into the internal thread blind hole 13, and their length is less than the length of the horizontal lifting hole.
[0025] The second end of the first rod 1 and the second end of the second rod 2 are both connected to lifting rings 3, which are used to cooperate with the hook of the crane.
[0026] Locking rings 4 are provided on the outer side of the second end of the first rod 1 and the outer side of the second end of the second rod 2. There are two locking rings 4. The two locking rings 4 are attached to the two sides of the lower part of the T-beam for centering and limiting, thereby making the hoisting balanced.
[0027] The first rod 1 has a first external threaded section 12 on the outer side of its second end, and the second rod 2 has a second external threaded section 22 on the outer side of its second end. The locking ring 4 has an internal threaded through hole in its middle. The two locking rings 4 are threadedly connected to the first external threaded section 12 and the second external threaded section 22 respectively through the internal threaded through hole, allowing the locking rings 4 to move axially along the lead screw and adjust their position. After installation, the threaded connection structure ensures that the locking rings 4 firmly fit against the side of the T-beam, keeping the lead screw and T-beam relatively fixed and preventing them from loosening. One end of the locking ring 4 has several circumferentially distributed triangular plates for easy direct rotation, and the other end of the locking ring 4 has a flat or rough surface for contact with the T-beam.
[0028] The first rod 1 has a first intermediate section 11 in its middle, the outer diameter of which is larger than the outer diameter of the first external thread section 12; the second rod 2 has a second intermediate section 21 in its middle, the outer diameter of which is larger than the outer diameter of the second external thread section 22. When the first rod 1 and the second rod 2 are fully connected and pass through the horizontal lifting hole of the T-beam, the first intermediate section 11 and the second intermediate section 21 are both completely located inside the lifting hole, the first external thread section 12 and the second external thread section 22 extend out of the lifting hole, and the lifting ring 3 is located on the T-beam side outside the lifting hole.
[0029] The connection between the lifting ring 3 and the first rod 1 and the second rod 2 is by welding. During the processing, the first rod 1 is first machined with an internal thread blind hole 13 and a first external thread section 12, and the second rod 2 is machined with a second external thread section 22 and a third external thread section 23. The first rod 1 after the above processing forms a first intermediate section 11 in the middle and the second rod 2 forms a second intermediate section 21 in the middle. Then, the two locking rings 4 are rotated and installed on the outside of the first external thread section 12 and the outside of the second external thread section 22, respectively. Finally, the lifting ring 3 is welded.
[0030] During the T-beam hoisting process, the first member 1 and the second member 2 are separated. Two workers insert the first member 1 and the second member 2 into the hoisting holes from both sides of the T-beam. With the lifting ring 3 on the outer end, the first member 1 and the second member 2 are connected and tightened through the internal threaded blind hole 13 and the third external thread section 23, making the first member 1 and the second member 2 a single unit. Then, the locking rings 4 on both sides are tightened symmetrically to prevent asymmetrical spacing between the reserved spaces on both sides, which could lead to instability of the center of gravity after hoisting. After the screw rods are installed, the T-beam can be hoisted to the designated area.
[0031] Specific embodiment 2 of the T-beam hoisting screw provided by this utility model: In Embodiment 1, since the first rod 1 and the second rod 2 enter the lifting hole from both sides of the T-beam, workers need to measure the length of the exposed part of the lifting hole on both sides to achieve centered and balanced lifting, which is a rather cumbersome process. Therefore, this embodiment sets up a centering auxiliary component 5. Please refer to [link to relevant documentation]. Figure 5 and Figure 6 A centering auxiliary component 5 is fitted on the outer side of the first external thread section 12 and the outer side of the second external thread section 22. After installation, the centering auxiliary component 5 is located on the inner side of both ends of the lifting hole.
[0032] There are two centering auxiliary parts 5. The two centering auxiliary parts 5 move axially along the outer side of the first external thread section 12 and the outer side of the second external thread section 22, respectively. During installation, the two centering auxiliary parts 5 are made to abut against the first intermediate section 11 and the second intermediate section 21, respectively. The outer end of the centering auxiliary part 5 is flush with the opening of the hoisting hole, which does not affect the tightening of the locking ring 4 and can ensure centering after installation, thereby ensuring the balance of the hoisting process.
[0033] In this embodiment, the centering auxiliary component 5 is made of elastic plastic and has a C-shaped cross-section, allowing it to be removed from the outside of the lead screw through the C-shaped opening. In some embodiments, when hoisting different T-beams, i.e., T-beams with different lower thicknesses, centering auxiliary components 5 of different lengths can be used. Using the centering auxiliary component 5, workers do not need to measure the extension length of the lifting rings 3 on both sides of the T-beam for quick centering and installation.
[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.
