Description

Technical Field

[0001] This utility model relates to the field of hoisting and positioning technology, specifically to an auxiliary positioning device for steel structure prefabricated hoisting. Background Technology

[0002] With the rapid development of steel structure buildings, the hoisting of steel structure components has become a critical and high-risk operation in construction. Existing steel structure components are usually large in size, heavy in weight, and complex in shape. The requirements for the posture and position control of the components during hoisting are extremely high. Even a slight deviation will affect the overall structural safety and construction progress.

[0003] For example, patent CN115520765A, published on December 27, 2022, discloses a hoisting and positioning auxiliary device for a steel structural column under a support beam. It includes an upper balancing assembly for connecting lifting equipment components, a lower balancing assembly for connecting the steel structural column, and connecting members at both ends to the upper and lower balancing assemblies to form a cavity. The cavity is used to accommodate the support beam. When hoisting the steel structural column under the support beam, the upper balancing assembly is first placed at a suitable position above the support beam, and then connected... The components are connected to the lower balancing assembly, positioning the support beam in a suitable position within the space enclosed by the upper balancing assembly, lower balancing assembly, and connectors. Finally, the steel structure is connected to the lower balancing assembly, thus completing the hoisting of the steel structural column under the support beam. Because the support beam is placed through the cavity between the upper and lower balancing assemblies, and the steel structural column is connected to the lower surface of the lower balancing assembly, the influence of the support beam is avoided during the hoisting of the steel structural column, improving the hoisting effect. In addition, it can effectively reduce the occurrence of positioning deviations and other problems during the construction of the steel structure.

[0004] Existing steel structure hoisting methods rely on crane operators and multiple workers to visually adjust the position and angle of components, which is inefficient and poses significant safety hazards. In particular, steel structure components are rigid and difficult to adjust manually, and there are swaying and positioning errors during hoisting, leading to repeated lifting and adjustment, which increases construction costs.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the following will be described in conjunction with the appendix. Figures 1-6 This invention will now be described in further detail.

[0028] This utility model provides a steel structure assembly hoisting auxiliary positioning device, including an aluminum baffle 1 with a right-angle structure. A servo motor 2 is fixedly installed on the side wall of the aluminum baffle 1. A winding column 3 is installed on the output end of the servo motor 2. A rope 4 is wound on the winding column 3. The other end of the rope 4 passes around the outside of the steel structure component 5 and is connected to the aluminum baffle 1. Based on the rotation of the servo motor 2, the servo motor 2 winds up the rope 4, and the rope 4 pulls the steel structure component 5 toward the aluminum baffle 1.

[0029] Specifically, in this embodiment, the aluminum baffle 1 is integrally right-angled. The servo motor 2 is mounted on the outer wall of the aluminum baffle 1. The winding column 3 at the output end of the servo motor 2 has a large diameter at both ends and a small diameter in the middle, resembling the shape of a waist drum. The rope 4 is wound around the middle area of ​​the winding column 3. The servo motor 2 drives the winding column 3 to rotate to release and rewind the rope 4, which is existing technology, and its principle will not be elaborated. In this embodiment, the steel structure component 5 is rectangular columnar, and the pre-embedded reinforcing bars 6 are distributed in a rectangular shape, with the pre-embedded reinforcing bars 6 extending a certain height above the ground to facilitate subsequent connection and construction. When it is necessary to install the steel structure component 5 and the pre-embedded reinforcing bars 6, the worker places the right-angled aluminum baffle 1 on the outside of the pre-embedded reinforcing bars 6. At this time, both right-angled sides of the aluminum baffle 1 face the pre-embedded reinforcing bars 6. For the reinforcing bar 6, adjust the distance between the right-angled side of the aluminum baffle 1 and the embedded reinforcing bar 6 so that this distance is equal to the theoretical distance between the bottom of the steel structure component 5 and the connection position to the embedded reinforcing bar 6 and the side of the steel structure component 5. Then, use a crane to lift the steel structure component 5 to a position about 30 centimeters above the embedded reinforcing bar 6 and suspend it. Then, the workers wrap the rope 4 around the steel structure component 5 once and connect the end of the rope 4 to the side of the aluminum baffle 1. Then, the servo motor 2 is started, and the servo motor 2 drives the winding column 3 to rotate synchronously. The winding column 3 winds up the rope 4, and the rope 4 applies a horizontal traction force to the steel structure component 5, so that the two side walls of the steel structure component 5 abut against the two right-angled sides of the aluminum baffle 1 respectively, completing the position adjustment of the steel structure component 5. After that, the workers weld the steel structure component 5 to the embedded reinforcing bar 6 to complete the installation of the steel structure component 5.

[0030] Preferably, the aluminum baffle 1 is also equipped with an integrated controller 12, a power module 13, and a distance sensor 14. The integrated controller 12 is used to process various sensor and image inputs and issue servo control commands. The power module 13 is used to provide a stable power supply. The distance sensor 14 is used to detect the distance between the steel structure component 5 and the aluminum baffle 1 in real time.

[0031] Specifically, the integrated controller 12, power module 13, and distance sensor 14 are all existing technologies, and their principles will not be elaborated here. When the distance sensor 14 detects that the steel structure component 5 is against the surface of the aluminum baffle 1, the distance sensor 14 transmits the distance signal to the integrated controller 12. The integrated controller 12 sends a stop command to the servo motor 2, and the servo motor 2 stops working, waiting for the subsequent connection processing of the steel structure component 5 and the pre-embedded steel bar 6.

[0032] Obviously, there are multiple locations on the construction site where steel structure components 5 need to be installed. In other words, there will be multiple pre-embedded steel bars 6 waiting to be connected to steel structure components 5. At this time, in order to ensure the accuracy of the connection between the pre-embedded steel bars 6 and steel structure components 5, it is necessary to measure the distance between the pre-embedded steel bars 6 and steel structure components 5 before each connection and adjust it so that the distance between the right-angle side of the aluminum baffle 1 and the pre-embedded steel bar 6 is equal to the theoretical distance from the bottom of the steel structure component 5 and the connection position of the pre-embedded steel bar 6 to the side of the steel structure component 5, thereby increasing the workload of the construction personnel.

[0033] To solve the above problems, preferably, the bottom of the aluminum baffle 1 is provided with multiple threaded connection holes 11, and limiters 7 are connected in the threaded connection holes 11. The limiters 7 are used to control the distance between the aluminum baffle 1 and the pre-embedded steel bars 6. The limiters 7 include abutment bars 71 and two connecting rods 72. The two connecting rods 72 correspond one-to-one with the multiple threaded connection holes 11. One end of the connecting rod 72 is connected to the corresponding threaded connection hole 11, and the other end of the connecting rod 72 is rotatably connected to the abutment bars 71. Multiple rotating grooves 73 are provided on the side of the abutment bars 71 near the connecting rods 72. The multiple rotating grooves 73 correspond one-to-one with the multiple connecting rods 72, and the ends of the connecting rods 72 are inserted into the corresponding rotating grooves 73. Furthermore, two sets of limiters 7 are provided, and the two sets of limiters 7 are respectively installed on the two side walls of the aluminum baffle 1.

[0034] Specifically, in this embodiment, the limiter 7 is located on the side of the aluminum baffle 1 near the embedded steel bar 6. Before adjusting the distance between the aluminum baffle 1 and the embedded steel bar 6, the length of the limiter 7 is pre-adjusted according to the size parameters of different steel structure components 5, so that the length of the limiter 7 is equal to the theoretical distance from the bottom of the steel structure component 5 to the side of the embedded steel bar 6. During adjustment, the operator drives the connecting rod 72 to rotate in the corresponding threaded connection hole 11 to adjust the extension length of the connecting rod 72. As the connecting rod 72 extends on the aluminum baffle 1, one end of the connecting rod 72 rotates in the rotating groove 73 on the abutment stop 71. Therefore, as the connecting rod 72 rotates, it does not drive the abutment stop 71. When the stop bar 71 rotates, the connecting rod 72 can only extend or shorten synchronously with the stop bar 71, thereby adjusting the length of the limiter 7. Since the connecting rod 72 is connected to the aluminum baffle 1 through the threaded connection hole 11, when the connecting rod 72 stops rotating, it cannot move horizontally along the threaded connection hole 11. After the length of the limiter 7 is adjusted, when installing the steel structure component 5 and the embedded steel bar 6, the aluminum baffle 1 with the adjusted length of the limiter 7 is placed on the outside of the embedded steel bar 6, so that the stop bar 71 on the limiter 7 can abut against the side wall of the embedded steel bar 6. At this time, the installation position of the steel structure component 5 can be quickly positioned, improving the installation efficiency between the steel structure component 5 and the embedded steel bar 6.

[0035] When the abutting strip 71 abuts against the embedded steel bar 6, there is a hard contact between the abutting strip 71 and the embedded steel bar 6. In order to reduce the wear of the abutting strip 71, a rubber sheet 74 can be fixedly installed on the side of the abutting strip 71 away from the connecting rod 72. By setting the rubber sheet 74, there is a buffer area between the abutting strip 71 and the embedded steel bar 6. When the rubber sheet 74 on the abutting strip 71 abuts against the surface of the embedded steel bar 6, the rubber sheet 74 is deformed by the compression of the embedded steel bar 6. The deformed area of ​​the rubber sheet 74 can wrap around one side of the embedded steel bar 6. At this time, the wrapping from the rubber sheet 74 can fix the position of the embedded steel bar 6, so that the embedded steel bar 6 remains relatively stable during the welding process with the steel structure component 5, and the welding deviation is reduced.

[0036] Obviously, as the rope 4 pulls the steel structure component 5 to align with the aluminum baffle 1, the steel structure component 5 is also prone to impacting the surface of the aluminum baffle 1. Because the steel structure component 5 has a large weight, it is easy for the aluminum baffle 1 to deform. Preferably, a buffer rubber pad 8 is installed on the surface of the aluminum baffle 1 that is close to the pre-embedded steel bar 6. The buffer rubber pad 8 is used to buffer the impact of the steel structure component 5 on the surface of the aluminum baffle 1.

[0037] Obviously, in this embodiment, the rope 4 can only pull some larger steel structure components 5. When the rope 4 is taut, the aluminum baffles 1 of the rope 4 will form a triangular space 15. If the cross-sectional area of ​​the steel structure component 5 is smaller than the space 15, even if the rope 4 is taut, the steel structure component 5 cannot come into contact with the surface of the aluminum baffle 1.

[0038] To solve the above problems, a connecting groove 9 is provided on the side wall of the aluminum baffle 1, and an avoidance notch 10 is provided on the side wall of the connecting groove 9. An adjusting baffle 101 is slidably installed in the avoidance notch 10, and the adjusting baffle 101 and the avoidance notch 10 are connected by a return spring 102. A groove 103 is provided on the end of the adjusting baffle 101 that contacts the rope 4, and a rolling ball 104 is provided at the bottom of the groove 103. The ball 104 is used to reduce the friction between the rope 4 and the groove 103.

[0039] Specifically, in this embodiment, the connecting groove 9 is arranged horizontally. When the return spring 102 is not under force, the side of the adjusting bar 101 away from the clearance notch 10 abuts against the side wall of the connecting groove 9. At this time, the rope 4 passes through the groove 103 on the adjusting bar 101. When it is necessary to pull some small steel structure components 5, as the servo motor 2 winds up the rope 4, the rope 4 applies pressure to the adjusting bar 101, causing the adjusting bar 101 to be retracted into the clearance notch 10. At this time, the return spring 102 connected to the adjusting bar 101 accumulates elastic potential energy. As the adjusting bar 101 is gradually retracted into the clearance notch 10, it is equivalent to one side of the triangular space 15 gradually becoming smaller, so that the area of ​​the space 15 is also continuously decreasing. Thus, under the traction of the rope 4, the steel structure component 5 with a small cross-section can be quickly positioned, thereby improving the connection efficiency between the steel structure component 5 and the pre-embedded steel bar 6.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
