Description

Technical Field

[0001] This application belongs to the field of T-beam hoisting technology, specifically relating to a multifunctional T-beam hoisting auxiliary device. Background Technology

[0002] T-beams are a common type of beam in building structures. They are characterized by their T-shaped cross-section. T-beams are widely used in long-span buildings and bridges, providing sufficient strength and stiffness. In building structures, T-beams can also be used to support cantilevered ceilings or other cantilevered structures.

[0003] In the construction of precast T-beams, gantry cranes or bridge erecting machines are generally used to lift the T-beams. However, the dimensions of the T-beams need to be flexibly adjusted according to the bridge span and design load, resulting in inconsistent T-beam sizes, making it difficult to use existing lifting equipment interchangeably. Whenever connecting T-beams of different sizes, the equipment needs to be specifically modified, including adjusting the lifting point spacing, replacing suitable lifting tools, and calibrating the hoisting mechanism parameters. These modifications are cumbersome, time-consuming, and labor-intensive, impacting work efficiency and the workload of employees. Utility Model Content

[0004] This application provides a multifunctional T-beam hoisting auxiliary device, which aims to solve the technical problems of frequent modification of hoisting tools and low work efficiency in the hoisting of T-beams of different widths in the prior art.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A multifunctional T-beam hoisting auxiliary device is provided, including an installation body, wherein the installation body has a first side, a second side, a third side and a fourth side connected in sequence; A first mounting groove that runs vertically through the middle of the first side is provided. A second mounting groove that runs vertically through the middle of the second side is provided; A third mounting groove that runs vertically through the middle of the third side surface is provided. A fourth mounting groove that runs vertically through the middle of the fourth side is provided. The depths of the first mounting slot, the second mounting slot, the third mounting slot, and the fourth mounting slot are all different.

[0006] In one possible implementation, the installation body includes: The upper fixing plate has a first upper working opening, a second upper working opening, a third upper working opening and a fourth upper working opening on its four sides respectively; A lower fixing plate is vertically spaced from the upper fixing plate. The lower fixing plate has a first lower working opening, a second lower working opening, a third lower working opening, and a fourth lower working opening corresponding to the upper fixing plate. A first mounting groove is formed between the first upper working opening and the first lower working opening; a second mounting groove is formed between the second upper working opening and the second lower working opening; a third mounting groove is formed between the third upper working opening and the third lower working opening; and a fourth mounting groove is formed between the fourth upper working opening and the fourth lower working opening. Multiple connecting plates are respectively connected between the upper fixing plate and the lower fixing plate.

[0007] In one possible implementation, the upper fixing plate has two arc-shaped plates on the same side, forming a guide space between the two arc-shaped plates. The guide space is connected to the corresponding first upper working port, second upper working port, third upper working port, or fourth upper working port. The arc-shaped plates are used to connect to the upper end of the bridge side.

[0008] In one possible implementation, the lower fixing plate is provided with multiple adapter plates on its outer periphery, with two adapter plates on the same side, forming an adapter space between the two adapter plates. The adapter space is connected to the corresponding first lower working port, second lower working port, third lower working port, or fourth lower working port. The adapter plate is used to connect to the lower end of the bridge side.

[0009] In one possible implementation, the adapter plate has inclined surfaces that slope outwards sequentially from top to bottom, and these inclined surfaces are in contact with the lower end face of the bridge side.

[0010] In one possible implementation, both the upper fixing plate and the lower fixing plate are made of steel or aluminum alloy.

[0011] In one possible implementation, the sides of the plurality of connecting plates are connected sequentially, and the tops of the plurality of connecting plates enclose a welding surface, the shape of which conforms to the outline of the upper fixing plate.

[0012] In one possible implementation, the arc-shaped plate and the upper fixing plate are integrally cast.

[0013] In one possible implementation, the depths of the first mounting slot, the second mounting slot, the third mounting slot, and the fourth mounting slot gradually increase.

[0014] In one possible implementation, the upper and lower edges of the first mounting slot, the second mounting slot, the third mounting slot, and the fourth mounting slot are respectively rounded.

[0015] Compared with the prior art, the multi-functional T-beam hoisting auxiliary device provided in this application has multiple installation grooves of different depths on multiple sides to adapt to T-beams of different widths: the four sequentially connected sides of the installation body are respectively opened with installation grooves of different depths. Due to the different depths of the installation grooves, when the device is engaged with the side of the T-beam hoisting point, the installation grooves of different depths can form a stable engagement with the side of the T-beam of different widths. At the same time, the vertically connected installation grooves provide a dedicated positioning channel for the hoisting wire rope. After the wire rope is inserted, it fits against the inner wall of the installation groove. During hoisting, the device and the side of the T-beam form a whole through friction and clamping force to avoid relative slippage. Ultimately, it can complete the hoisting of T-beams of different widths without modifying the gantry crane / bridge erecting machine hoisting tool. The device can adapt to multiple beam widths with four installation slots of different depths, eliminating the need for any destructive modifications to the gantry crane / bridge erecting machine's lifting equipment. This avoids the shortened lifespan caused by frequent equipment modifications, completely eliminating the need for equipment modification and significantly reducing operating costs and overall work time. The tight engagement between the installation slot and the side of the T-beam, combined with the dedicated positioning of the wire rope within the installation slot, forms a stable triangular force-bearing structure, providing dual protection against loosening due to friction and clamping force. At the same time, the vertically connected installation slot prevents wire rope deviation, further reducing the probability of lifting accidents. The main installation body is an integrated structure with no complex moving parts, allowing for on-site fabrication. The vertically connected installation slot facilitates cleaning, transportation, and relocation. Attached Figure Description

The following description of at least one exemplary embodiment is actually illustrative only and is in no way intended to limit this application or its application or use.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Additionally, "multiple" and "several" mean two or more, unless otherwise explicitly specified.

[0024] Please refer to the following: Figures 1 to 8 The multifunctional T-beam hoisting auxiliary device provided in this application will now be described. The multifunctional T-beam hoisting auxiliary device includes an installation body 100, which has a first side, a second side, a third side, and a fourth side connected in sequence; a first mounting groove 101 that runs vertically through the middle of the first side; a second mounting groove 102 that runs vertically through the middle of the second side; a third mounting groove 103 that runs vertically through the middle of the third side; and a fourth mounting groove 104 that runs vertically through the middle of the fourth side; wherein the depths of the first mounting groove 101, the second mounting groove 102, the third mounting groove 103, and the fourth mounting groove 104 are all different.

[0025] It should be noted that this application utilizes multi-sided installation grooves of varying depths to adapt to T-beams of different widths: the four sequentially connected sides of the installation body 100 are respectively provided with installation grooves of different depths. Due to the different depths of the installation grooves, when the device is engaged with the side of the T-beam lifting point, the installation grooves of different depths can form a stable engagement with the side of the T-beam of different widths. At the same time, the vertically connected installation grooves provide a dedicated positioning channel for the lifting wire rope 300. After the wire rope 300 is inserted, it fits against the inner wall of the installation groove. During lifting, the device and the side of the T-beam form a whole through friction and clamping force, avoiding relative slippage. Ultimately, this allows for the lifting of T-beams of different widths without the need to modify the gantry crane / bridge erecting machine lifting equipment.

[0026] In practice, the usage process of this embodiment is as follows: Based on the actual width of the T-beam to be hoisted, select the first mounting slot 101 / second mounting slot 102 / third mounting slot 103 / fourth mounting slot 104 on the mounting body 100 with matching depth; Move the main body 100 to the preset position of the T-beam lifting point, so that the opening of the selected mounting slot faces the side of the T-beam, and slowly push the device until the side of the T-beam is completely inserted into the first mounting slot 101 / second mounting slot 102 / third mounting slot 103 / fourth mounting slot 104, ensuring that the device fits the side of the T-beam without gaps. Pass the hoisting wire rope 300 through the bottom of the T-beam and slowly move it to the hoisting point. Place the hoisting section of the wire rope 300 into the corresponding installation groove, ensuring that the wire rope 300 is completely lowered into the bottom of the installation groove without any offset or sag. Start the gantry crane or bridge erecting machine, and slowly lift the wire rope 300 upwards until the wire rope 300 forms a tight clamping state with the inner wall of the installation groove and the side of the T-beam. After observing the stability of the fit between the device and the T-beam, lift the T-beam at a uniform speed to complete the hoisting.

[0027] The multi-functional T-beam hoisting auxiliary device provided in this embodiment, compared with the prior art, achieves one device to adapt to multiple beam widths through four installation slots of different depths. It does not require any destructive modification to the gantry crane / bridge erecting machine's lifting equipment, avoiding the shortened lifespan caused by frequent equipment modifications, completely eliminating the equipment modification process, and significantly reducing working costs and overall work time. The tight engagement between the installation slot and the side of the T-beam, combined with the dedicated positioning of the wire rope 300 within the installation slot, forms a stable triangular force-bearing structure, providing dual protection of friction and clamping force, eliminating the risk of loosening. At the same time, the vertically connected installation slot prevents the wire rope 300 from shifting, further reducing the probability of hoisting accidents. The main installation body 100 is an integrated structure with no complex moving parts, can be fabricated on-site, and the vertically connected installation slot facilitates cleaning, transportation, and relocation.

[0028] In practical implementation, the installation groove depth gradient design on the four sides of the installation body 100 can cover the width of most T-beams in the background technology; the vertically connected installation groove structure is not only suitable for T-beams, but can also be used for hoisting steel structures with similar structural shapes (such as precast blocks of crash barriers and wet joint templates), which solves the limitation of traditional hoisting tools being used for one thing at a time. It is especially suitable for mixed construction scenarios with multiple beams, such as bridges in mountainous areas and urban elevated roads, and increases the adaptability of the device.

[0029] In some embodiments, see Figures 1 to 4The main installation body 100 includes an upper fixing plate 110, a lower fixing plate 120, and multiple connecting plates 130. The upper fixing plate 110 has a first upper working opening 111, a second upper working opening 112, a third upper working opening 113, and a fourth upper working opening 114 on its four sides respectively. The lower fixing plate 120 is arranged vertically at intervals from the upper fixing plate 110, and the lower fixing plate 120 has a first lower working opening 121, a second lower working opening 122, a third lower working opening 123, and a fourth lower working opening 124 corresponding to the upper fixing plate 110. A first mounting groove 101 is formed between the first upper working opening 111 and the first lower working opening 121, a second mounting groove 102 is formed between the second upper working opening 112 and the second lower working opening 122, a third mounting groove 103 is formed between the third upper working opening 113 and the third lower working opening 123, and a fourth mounting groove 104 is formed between the fourth upper working opening 114 and the fourth lower working opening 124. Multiple connecting plates 130 are respectively connected between the upper fixing plate 110 and the lower fixing plate 120.

[0030] This embodiment employs a modular structure, with upper and lower fixed plates 110 and 120 spaced vertically, forming a frame-like load-bearing structure in conjunction with multiple connecting plates 130. The connecting plates 130 can evenly transfer the lifting force borne by the upper fixed plate 110 to the lower fixed plate 120, and then distribute it to the sides of the T-beam through the lower fixed plate 120, avoiding excessive local pressure. The device is divided into upper fixed plate 110, lower fixed plate 120, and connecting plates 130. The weight of each component can be controlled within a transportable range, allowing ordinary workers to handle it. On-site assembly is achieved through welding or bolting, facilitating transportation and processing. If the working opening of the upper fixed plate 110 wears down, only the upper fixed plate 110 needs to be replaced; the same applies when the connecting plate 130 or lower fixed plate 120 is damaged, eliminating the need to discard the entire device and reducing maintenance costs. Simultaneously, the connection points between the connecting plate 130 and the upper and lower fixed plates 110 and 120 can be periodically inspected and reinforced to prevent overall failure due to local loosening, extending the service life.

[0031] In some embodiments, see Figure 5 The upper fixing plate 110 has two arc-shaped plates 115 on the same side, and a guide space is formed between the two arc-shaped plates 115. The guide space is connected to the corresponding first upper working port 111, second upper working port 112, third upper working port 113, or fourth upper working port 114. The arc-shaped plates 115 are used to connect to the upper end of the side of the bridge 200.

[0032] The two arc-shaped plates 115 on the same side of the device form a funnel-shaped guide space and are connected to the corresponding upper working port. The wire rope 300 does not need to be precisely aligned when it is laid. After the wire rope 300 is put into the guide space, it will automatically slide into the corresponding upper working port along the curved surface of the arc-shaped plate 115. The whole process does not require manual adjustment by workers, reducing labor intensity and reducing the risk of high-altitude operation. The arc-shaped plate 115 adopts a curved surface design, and the contact with the upper side of the T-beam is a surface contact, which increases the contact area and further protects the integrity of the T-beam surface. After the arc-shaped plate 115 is attached to the upper side of the T-beam, it will form a lateral limit. If the device has a tendency to shift left or right, the inner wall of the arc-shaped plate 115 will generate lateral friction with the side of the T-beam to prevent the shift. At the same time, the guide space is connected to the first upper working port 111, the second upper working port 112, the third upper working port 113, and the fourth upper working port 114. The sliding path of the wire rope 300 in the guide space is fixed, which further restricts the lateral displacement of the device and ensures that the device is always directly above the T-beam lifting point.

[0033] In some embodiments, see Figure 6 The lower fixing plate 120 has multiple adapter plates 125 on its outer periphery, with two adapter plates 125 on the same side. An adapter space is formed between the two adapter plates 125. The adapter space is connected to the corresponding first lower working port 121, second lower working port 122, third lower working port 123, or fourth lower working port 124. The adapter plate 125 is used to connect to the lower end of the side of the bridge 200.

[0034] In this embodiment, the adapter plate 125 of the lower fixing plate 120 is connected to the lower end of the side of the T-beam, and the arc plate 115 of the upper fixing plate 110 is connected to the upper end of the T-beam, increasing the contact surface with the T-beam and improving the hoisting stability. The adapter space formed by the two adapter plates 125 is connected to the lower working opening and corresponds vertically to the guide space of the upper fixing plate 110. When the wire rope 300 passes through the bottom of the T-beam, the lower end will automatically slide into the corresponding first lower working opening 121 / second lower working opening 122 / third lower working opening 123 / fourth lower working opening along the adapter space. The adapter plate 124 eliminates the need for workers to manually adjust the lower position, avoiding dangerous operations at the bottom of the T-beam and reducing the risk of working at height. The adapter space provides a dedicated channel for the wire rope 300, which does not directly contact the T-beam concrete but instead contacts the inner wall of the adapter plate 125, further protecting the lower structure of the T-beam. The adapter plate 125 can be adjusted according to the shape of the lower T-beam, and the width of the adapter space can be flexibly set by adjusting the spacing of the adapter plates 125. Simply replace the adapter plates 125 with different spacings without having to remake the lower fixing plate 120.

[0035] In some embodiments, see Figures 2 to 4The adapter plate 125 has inclined surfaces that slope outwards sequentially from top to bottom, and these inclined surfaces fit against the lower end face of the side of the bridge 200. The inclined surfaces of the adapter plate 125 can precisely match the inclination angle of the lower end face of the T-beam, making the stress on the adapter plate 125 more even. At the same time, the inclined surfaces are curved, avoiding hard collisions between the flat surface and the lower end face of the T-beam, reducing the risk of damage to the concrete at the lower end of the T-beam. During lifting, the pressure of the T-beam on the adapter plate 125 is transmitted along the normal direction of the inclined surfaces, generating a component force pointing towards the side of the T-beam. This component force makes the fit between the adapter plate 125 and the lower end face of the T-beam tighter, forming a self-locking effect and avoiding the gaps in fit caused by the loosening of the wire rope 300 during lifting using traditional devices.

[0036] In some embodiments, the upper fixing plate 110 and the lower fixing plate 120 are both made of steel or aluminum alloy.

[0037] This embodiment provides three materials: steel, aluminum alloy, and stainless steel. Steel (such as Q235 steel) has high strength (tensile strength ≥375MPa) and can be used for 200-ton heavy T-beams. Aluminum alloy (such as 6061 aluminum alloy) has a density of only 1 / 3 that of steel, is lightweight, and has sufficient strength (tensile strength ≥276MPa), making it suitable for 50-100 ton light T-beams, and making transportation and installation easier. Stainless steel (such as 304 stainless steel) has a tensile strength ≥515MPa and is corrosion resistant, making it suitable for 100-180 ton medium T-beams. This allows for material selection as needed, covering all common T-beam load ranges, without the need to customize special devices for different loads.

[0038] In some embodiments, see Figure 1 Multiple connecting plates 130 are connected sequentially on their sides, and the tops of the multiple connecting plates 130 enclose a welding surface. The shape of the welding surface conforms to the shape of the upper fixing plate 110.

[0039] In this embodiment, multiple connecting plates 130 are sequentially connected on their sides, and the welding surface enclosing the top is completely fitted with the shape of the upper fixed plate 110 without any welding gaps, thus improving weld strength and significantly enhancing structural safety. The sequential connection of the connecting plates 130 forms a ring frame, which can simultaneously withstand vertical, lateral, and torsional forces, improving torsional stiffness. At the same time, the frame structure also provides stable support for the lower fixed plate 120, ensuring that the upper fixed plate 110 and the lower fixed plate 120 remain parallel, preventing the T-beam from tilting due to device deformation and ensuring the installation accuracy of each span of the T-beam. The welding surface formed by the sequential connection of the connecting plates 130 can be flexibly adjusted according to the shape of the upper fixed plate 110 (e.g., when the upper fixed plate 110 is floral, the welding surface enclosed by the connecting plates 130 is also of the corresponding floral shape), without the need to redesign the shape and size of the connecting plates 130, resulting in high processing flexibility, further enhancing adaptability, and reducing customized processing costs.

[0040] In some embodiments, the arc-shaped plate 115 and the upper fixed plate 110 are integrally cast. The integral casting of the arc-shaped plate 115 and the upper fixed plate 110 without any welds allows for uniform stress distribution throughout the structure, preventing stress concentration-induced cracking. This integral casting allows for mass production, shortens processing cycles, and improves production efficiency, meeting the bulk procurement needs of the large-scale bridge project 200.

[0041] In some embodiments, the depths of the first mounting slot 101, the second mounting slot 102, the third mounting slot 103, and the fourth mounting slot 104 gradually increase. In this embodiment, the gradually increasing depth of the four mounting slots creates a continuous gradient that accommodates a range of beam widths, making it suitable for bridges of varying spans (e.g., Project 200). One set of equipment can meet the hoisting requirements of all T-beam spans. Workers can quickly determine the appropriate mounting slot through visual comparison without measurement, further reducing the operational threshold.

[0042] In some embodiments, the upper and lower edges of the first mounting groove 101, the second mounting groove 102, the third mounting groove 103, and the fourth mounting groove 104 are rounded. The rounded edges of the mounting grooves result in smooth surfaces without sharp protrusions, allowing the wire rope 300 to make curved contact with the edges, preventing scratches. This extends the service life of the wire rope 300 and significantly reduces cumulative costs. The rounded edge design evenly distributes stress in the rounded area, reducing edge stress and effectively preventing cracks caused by stress concentration. The rounded edges ensure a smooth sliding path for the wire rope 300 without any jamming points, allowing it to slide at a uniform speed during lifting, ensuring stable T-beam lifting, guaranteeing installation accuracy, reducing subsequent adjustment procedures, and improving construction efficiency.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
