Description

Technical Field

[0001] This utility model relates to the field of steel corridor construction technology, and more specifically, to a double-bracketed steel connecting beam lifting and hoisting device with a crossbeam. Background Technology

[0002] A steel connecting corridor is a passageway or bridge constructed using steel structures to connect different buildings. In common steel connecting corridor structures, both ends of the corridor are connected to the steel columns of the building via supports. The supports and the steel columns of the building form a supporting structure. During hoisting, the steel connecting corridor is lifted and placed on the supporting structure.

[0003] For the hoisting of steel connecting corridors, the commonly used method is to leave a section at each end unassembled temporarily. This allows the steel connecting corridor to avoid obstacles such as cantilevered structures supporting it during the lifting process. Once it has been lifted above the installation height, the two ends of the steel connecting corridor are then joined together to form a whole and lowered into place. This method involves long working hours at height, a large workload, and increases the difficulty of quality control in assembling the steel connecting corridor and the safety risks of the hoisting operation. Utility Model Content

[0004] The purpose of this invention is to provide a double-bracketed steel beam lifting and hoisting device with a crossbeam to solve the above-mentioned defects of the prior art.

[0005] This utility model is achieved through the following technical solution:

[0006] A double-bracketed steel connecting beam with a crossbeam is used for lifting and hoisting. It includes a pair of lifting platforms fixed to the buildings at both ends of the steel connecting corridor. Each lifting platform includes a crossbeam and two brackets arranged at intervals along the transverse direction. The top of the crossbeam is provided with a first set of lifting components and a second set of lifting components. Both the first set of lifting components and the second set of lifting components include several lifting devices and several lifting ropes. The upper end of the lifting rope is connected to the lifting device, and the lower end of the lifting rope is connected to the steel connecting corridor. The steel connecting corridor is lifted as a whole by the first lifting component, and then the steel connecting corridor is moved to the top of the supporting structure by the second set of lifting components.

[0007] The crossbeam includes a top plate, a bottom plate, and two side plates. The two side plates are welded side by side between the top plate and the bottom plate. The top of the top plate is provided with a mounting bracket for installing the lifting device. A stiffening plate is provided between the top plate and the bottom plate below the mounting bracket.

[0008] Optionally, two hanging brackets are provided at both ends of the top of the top plate, one of which is used to install the lifting device of the first set of lifting components, and the other is used to install the lifting device of the second set of lifting components.

[0009] Optionally, of the two hangers at the same end of the top plate, one hanger is located on one side of the corbel, and the other hanger is located above the corbel.

[0010] Optionally, the bracket includes a flat beam and a sloping beam, one end of the flat beam is fixed to the building, the upper end of the sloping beam is welded to the middle of the flat beam, and the lower end of the sloping beam is fixed to the building.

[0011] Optionally, the flat beam includes two flat bars and several first connecting bars, with the two flat bars arranged side by side and the first connecting bars welded between the two flat bars.

[0012] Optionally, the flat rod has a box-shaped structure, and the first connecting rod is an I-beam.

[0013] Optionally, the inclined beam includes two inclined rods and several second connecting rods, with the two inclined rods arranged side by side and the second connecting rods welded between the two inclined rods.

[0014] Optionally, the diagonal brace has a box-shaped structure, and the second connecting rod is an I-beam.

[0015] The technical solution of this utility model has at least the following advantages and beneficial effects: In this utility model, the steel connecting corridor is lifted by the first set of lifting components (ensuring that the steel connecting corridor is staggered from the supporting structure during lifting), and the steel connecting corridor is pulled to the top of the supporting structure by the second set of lifting components, and then lowered onto the supporting structure. That is, this invention adopts the method of hoisting by lifting as a whole and then jumping to the position. Compared with the existing method, the operation time is shorter and the workload is smaller, which reduces the difficulty of quality control of steel connecting corridor assembly and the safety risks of hoisting operation. In addition, the crossbeam is welded to a top plate, a bottom plate and two side plates, forming an overall box-shaped structure, which reduces weight while ensuring support strength. At the same time, a stiffening plate is provided between the top plate and the bottom plate below the lifting seat to further improve the strength of the stress-bearing parts and improve the reliability of hoisting.

Detailed Implementation

[0025] refer to Figures 1-5 A double-bracket steel connecting beam lifting device with a crossbeam includes a pair of lifting platforms 1 fixed to the buildings 8 at both ends of the steel connecting corridor 7. The pair of lifting platforms 1 are symmetrically arranged. Each lifting platform 1 includes a crossbeam 102 and two brackets 101 arranged at intervals along the transverse direction (it should be understood that the transverse direction usually refers to the width direction of the steel connecting corridor 7, and the longitudinal direction refers to the length direction of the steel connecting corridor 7, and the term "transverse direction" in the following text is also interpreted in this way). The crossbeam 102 is used to bear the weight of the steel connecting corridor 7, which facilitates better distribution of the force to the brackets 101 and transfer to the building 8, thereby improving the reliability of the lifting.

[0026] The top of the crossbeam 102 is equipped with a first set of lifting components 3 and a second set of lifting components 4. Both the first set of lifting components 3 and the second set of lifting components 4 include several lifting devices 6 and several lifting ropes 5. The upper end of the lifting rope 5 is connected to the lifting device 6, and the lower end of the lifting rope 5 is connected to the steel connecting corridor 7. Alternatively, the lifting device 6 is a hydraulic synchronous lifting device. In practical applications, the steel connecting corridor 7 is lifted by the first set of lifting components 3 (ensuring that the steel connecting corridor 7 is staggered from the support structure 801 during lifting). The second set of lifting components 4 pulls the steel connecting corridor 7 to jump above the support structure 801, and then lowers the steel connecting corridor 7 onto the support structure. That is, the present invention adopts the method of hoisting by lifting as a whole and then jumping to the position. Compared with the existing method, the operation time is shorter, the workload is smaller, and the difficulty of assembling the steel connecting corridor 7 and the safety risks of hoisting operations are reduced.

[0027] refer to Figure 6 and Figure 8As an alternative, in this embodiment, the corbel 101 includes a flat beam 1011 and a diagonal beam 1012. One end of the flat beam 1011 is fixed to the building 8, the upper end of the diagonal beam 1012 is welded to the middle of the flat beam 1011, and the lower end of the diagonal beam 1012 is fixed to the building 8. The flat beam 1011, the diagonal beam 1012, and the building 8 constitute a triangular stable support structure. In other embodiments, the corbel 101 can of course be designed as other structures that can meet the support requirements.

[0028] To reduce weight while ensuring support strength, as an option, the specific structures of the flat beam 1011 and the inclined beam 1012 in this embodiment are as follows: The flat beam 1011 includes two flat rods 10111 and several first connecting rods 10112. The two flat rods 10111 are arranged side by side, and the first connecting rods 10112 are welded between the two flat rods 10111. Further, the flat rods 10111 have a box-shaped structure, and the first connecting rods 10112 are I-beams. The inclined beam 1012 includes two inclined rods 10121 and several second connecting rods 10122. The two inclined rods 10121 are arranged side by side, and the second connecting rods 10122 are welded between the two inclined rods 10121. The inclined rods 10121 have a box-shaped structure, and the second connecting rods 10122 are I-beams. It is worth noting that the bracket 101 has a double-piece structure with a gap in the middle, which does not obstruct the passage of the lifting rope 5 while ensuring strength. It is easy to understand that in other embodiments, the flat beam 1011 and the inclined beam 1012 may also adopt other structures.

[0029] refer to Figure 6 and Figure 7 In this embodiment, the crossbeam 102 includes a top plate 1021, a bottom plate 1022, and two side plates 1023. The two side plates 1023 are welded side-by-side between the top plate 1021 and the bottom plate 1022, forming a box-shaped structure that reduces weight while ensuring support strength. The top of the top plate 1021 is provided with a mounting bracket 2 for installing the lifting device 6. A stiffening plate 1024 is provided below the mounting bracket 2 between the top plate 1021 and the bottom plate 1022. The main function of the stiffening plate 1024 is to ensure sufficient strength after opening a hole (for the lifting rope 5 to pass through) in the crossbeam 102 at the position below the mounting bracket 2. In practical applications, stiffening plates 1024 are provided on the outer sides of both side plates 1023. The upper end of the stiffening plate 1024 is welded to the top plate 1021, and the lower end is welded to the bottom plate 1022.

[0030] Two hanging brackets 2 are provided at both ends of the top of the top plate 1021. One hanging bracket 2 is used to install the lifting device 6 of the first set of lifting components 3, and the other hanging bracket 2 is used to install the lifting device 6 of the second set of lifting components 4. Furthermore, of the two hanging brackets 2 at the same end of the top plate 1021, one hanging bracket 2 is located on one side of the bracket 101, and the other hanging bracket 2 is located above the bracket 101.

[0031] Since the two lifting seats 2 at the same end of the crossbeam 102 are spaced laterally, in practical applications, a lateral jump method is used to achieve hoisting. Specifically, the operation method includes the following steps:

[0032] S1. Install lifting platform 1, that is, install bracket 101 (the height of bracket 101 is 10-12m above the support structure 801) and crossbeam 102, and weld hanging seat 2 on the top of crossbeam 102;

[0033] S2. Install the first set of lifting components 3 and connect the hoisting ropes 5 of the first set of lifting components 3 to the steel connecting corridor 7 on the ground. At the same time, tension the hoisting ropes 5 of the first set of lifting components 3. If the tension of each hoisting rope 5 is large, it can be adjusted by tensioning a single hoisting rope 5.

[0034] S3. Simultaneously lift the hoisting rope 5 of the first lifting component 3 to raise the steel connecting corridor 7 to the target height (reference). Figure 1 In practical applications, the steel corridor 7 is raised to 1-2m above the top surface of the supporting structure 801 and then paused to check the elevation and ensure that the height difference between the bottom of the steel corridor 7 and the top surface of each supporting structure 801 is no more than 5mm. After that, the steel corridor 7 is suspended in the air.

[0035] S4. Install the second set of lifting components 4, and connect the hoisting rope 5 of the second set of lifting components 4 to the steel connecting corridor 7, while tensioning the hoisting rope 5 of the second set of lifting components 4 (refer to...). Figure 2 Similarly, if the tension of each of the five suspension ropes differs significantly, it can be adjusted by tightening a single suspension rope.

[0036] S5. Simultaneously lift the hoisting rope 5 of the second lifting component 4, causing the steel connecting corridor 7 to shift laterally until both ends are in the correct position above the supporting structure 801 (reference). Figure 3 );

[0037] S6. Lower the steel connecting corridor 7 onto the supporting structure 801 (reference) Figure 4 During the lowering process, the lateral movement of the steel connecting corridor 77 is observed through the host computer, and the balance is adjusted in a timely manner.

[0038] In this embodiment, the second lifting assembly 4's hoisting rope 5 is designed to be fully stressed after the jump to the position. That is, after the jump to the position, the second lifting assembly 4's hoisting rope 5 is in a vertical downward state, while the first lifting assembly 3's hoisting rope 5 is in a bent and relaxed state. In this case, the first lifting assembly 3's hoisting rope 5 can be disassembled first before the steel connecting corridor 7 is lowered. Alternatively, the hoisting ropes 5 of both lifting assemblies can be extended together to lower the steel connecting corridor 7, but it should be ensured that the first lifting assembly 3's hoisting rope 5 is always in a stress-free state during the lowering process.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
