Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, specifically to a propulsion and fixing device for a steel structure cantilever support. Background Technology

[0002] In modern construction engineering, steel structures are widely used in large commercial complexes, industrial plants, bridges and other projects due to their advantages such as high strength, light weight and fast construction speed. During the installation of steel structures, cantilever support devices are crucial to ensuring structural stability and safety, but existing devices have many problems.

[0003] Firstly, construction efficiency is low. The current cantilever support device lacks propulsion. When pushing the steel structure cantilever support to the predetermined position, the existing cantilever support device does not have an effective propulsion device. Workers can only push it manually with crowbars, jacks, etc. The propulsion process is not smooth and is prone to jamming, displacement and other problems, which increases the installation difficulty and time cost. At the same time, after the steel structure cantilever support is pushed to the designated position, the existing device only uses simple temporary fixing methods such as rope binding, which has poor reliability. When subsequent construction or affected by external factors, the steel structure is prone to displacement or loosening, affecting the overall stability and safety of the steel structure.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This utility model provides a technical solution: a propulsion and fixing device for a steel structure cantilever support, comprising:

[0027] A base 1, a rotating shaft 3 is rotatably mounted on the base 1, a bushing 4 is rotatably connected to the rotating shaft 3, an adjusting seat 5 is fixedly connected to the bushing 4, and a hydraulic cylinder 14 is rotatably connected to the top surface of the base 1, with the telescopic end of the hydraulic cylinder 14 hinged to the bottom surface of the adjusting seat 5.

[0028] The propulsion assembly includes multiple drive wheels 6 equally spaced on the rotating shaft 3, driven wheels 7 symmetrically mounted to the front end of the adjusting seat 5, a transmission belt 8 connecting the drive wheels 6 and the driven wheels 7, and a drive component for driving the rotating shaft 3 to rotate.

[0029] The fixing component includes a gantry frame 16 that is disposed on the top surface of the adjusting seat 5 and can slide along the length of the adjusting seat 5. A bidirectional lead screw 20 is rotatably mounted on the gantry frame 16, and two clamping arms 19 are threadedly connected to the bidirectional lead screw 20.

[0030] Specifically, the device integrates propulsion and fixing functions. The angle of the adjusting seat 5 can be flexibly adjusted by the hydraulic cylinder 14 to adapt to different installation scenarios. The propulsion component uses the transmission belt 8 to achieve smooth propulsion, avoiding the problems of unevenness and deviation caused by manual propulsion. The fixing component drives the clamping arm 19 through the bidirectional screw 20, which can reliably fix the steel structure cantilever support, improving construction efficiency and installation stability.

[0031] See Figure 1 The driving component includes a drive motor 10 mounted on the top surface of the base 1. The drive end of the drive motor 10 is connected to a first sprocket 11. A second sprocket 12 is fixedly mounted on the outer wall of the rotating shaft 3. A transmission chain 13 is connected between the first sprocket 11 and the second sprocket 12.

[0032] Specifically, after the drive motor 10 starts, its drive end drives the first sprocket 11 to rotate. The first sprocket 11 transmits power to the second sprocket 12 through the transmission chain 13. Since the second sprocket 12 is fixed on the outer wall of the rotating shaft 3, it drives the rotating shaft 3 to rotate, thereby providing power to the propulsion assembly.

[0033] See Figure 3 The top and bottom surfaces of the adjusting seat 5 are provided with support plates 9, the support plates 9 correspond to the positions of the transmission belt 8, and the outer surface of the support plates 9 is in contact with the inner surface of the transmission belt 8.

[0034] Specifically, the support plate 9 enhances the transmission stability of the transmission belt 8, ensures the reliable operation of the propulsion assembly, improves propulsion efficiency, and also extends the service life of the transmission belt 8.

[0035] See Figure 2 A sliding groove extending along the width direction of the adjusting seat 5 is provided on the gantry frame 16, and the clamping arm 19 is slidably connected to the inside of the sliding groove.

[0036] Specifically, the sliding groove provides guidance for the movement of the clamping arm 19, making the movement of the clamping arm 19 more stable and accurate, ensuring the clamping effect of the fixing component on the steel structure cantilever support, and improving the reliability of the fixing.

[0037] See Figure 1 A servo motor 21 is installed on the gantry frame 16, and the drive end of the servo motor 21 is connected to one end of the bidirectional lead screw 20.

[0038] Specifically, the servo motor 21 has precise control performance, which can accurately control the rotation angle and speed of the bidirectional lead screw 20, thereby accurately controlling the moving distance and clamping force of the clamping arm 19, improving the operating accuracy and automation of the fixing component.

[0039] See Figure 1 and Figure 4A guide rod 17 extending along the length of the adjusting seat 5 is slidably mounted on the front end face of the gantry frame 16. Multiple guide rollers 18 arranged at equal intervals are rotatably mounted on the bottom surface of the guide rod 17. The guide rod 17 is connected to the clamping arm 19.

[0040] Specifically, when the clamping arm 19 moves, it drives the guide rod 17 to move, and the guide roller 18 rolls on the surface of the steel structure cantilever support, playing a guiding and assisting role in propulsion. The setting of the guide rod 17 and the guide roller 18 further improves the stability and accuracy of the propulsion process of the steel structure cantilever support, reduces the deviation and jamming phenomenon during the propulsion process, and also helps the fixing components to better position and clamp the steel structure cantilever support.

[0041] See Figure 1 A limit switch 15 is installed on the top surface of the base 1, and the limit switch 15 cooperates with the oil cylinder 14.

[0042] Specifically, the limit switch 15 ensures the accuracy and safety of the angle adjustment of the adjusting seat 5, avoids excessive extension and retraction of the cylinder 14 which could damage the device or cause inaccurate installation, and improves the overall reliability and operational safety of the device.

[0043] See Figure 1 The base 1 has two bearing seats 2 on its rear side. The two bearing seats 2 are symmetrical along the width direction of the base 1, and the rotating shaft 3 is rotatably connected between the two bearing seats 2.

[0044] Specifically, the installation of bearing seat 2 enhances the stability and reliability of rotating shaft 3, ensures the normal operation of propulsion components, and improves the overall performance and service life of the device.

[0045] Working principle:

[0046] Device foundation and angle adjustment:

[0047] The base 1 serves as the supporting foundation for the entire device. Two bearing seats 2 on the rear side are symmetrically arranged along the width direction of the base 1. The rotating shaft 3 is rotatably connected between the two bearing seats 2, providing stable rotational support for subsequent components. The bushing 4 is rotatably connected to the rotating shaft 3. The adjusting seat 5 is fixed to the bushing 4. The hydraulic cylinder 14 is rotatably connected to the top surface of the base 1. Its extension end is hinged to the bottom surface of the adjusting seat 5. When the hydraulic cylinder 14 extends or retracts, it will push the adjusting seat 5 to rotate around the rotating shaft 3, thereby realizing the adjustment of the angle of the adjusting seat 5 to adapt to different installation conditions. The limit switch 15 is installed on the top surface of the base 1 and cooperates with the hydraulic cylinder 14. When the hydraulic cylinder 14 extends or retracts to a specific position, it triggers the limit switch 15, causing the hydraulic cylinder 14 to stop moving, ensuring the accuracy of the angle adjustment of the adjusting seat 5.

[0048] Advancing component work:

[0049] The drive motor 10 is mounted on the top surface of the base 1, and its drive end is connected to the first sprocket 11. The outer wall of the rotating shaft 3 is fixed with a second sprocket 12. The first sprocket 11 and the second sprocket 12 are connected by a transmission chain 13. After the drive motor 10 starts, it drives the first sprocket 11 to rotate and transmits power to the second sprocket 12 through the transmission chain 13, thereby causing the rotating shaft 3 to rotate. Multiple drive wheels 6, which are equally spaced and mounted on the rotating shaft 3, rotate together with the rotating shaft 3. The driven wheels 7, which are symmetrical to the drive wheels 6 and rotatably mounted at the front end of the adjusting seat 5, are connected to the drive wheels 6 through a transmission belt 8. When the drive wheels 6 rotate, they drive the driven wheels 7 to rotate through the transmission belt 8. The movement of the transmission belt 8 is used to advance the steel structure cantilever support. The support plates 9 set on the top and bottom surfaces of the adjusting seat 5 have their outer surfaces in contact with the inner surfaces of the transmission belt 8, which support the transmission belt 8, prevent the transmission belt 8 from deforming or sagging under force, and ensure the stability of the advancement process.

[0050] Fixed component operation:

[0051] A gantry frame 16 is mounted on the top surface of the adjusting seat 5 and can slide along the length of the adjusting seat 5. A bidirectional lead screw 20 is rotatably mounted on the gantry frame 16, and two clamping arms 19 are threadedly connected to the bidirectional lead screw 20. A sliding groove on the gantry frame 16 extends along the width of the adjusting seat 5, and the clamping arms 19 slide within the sliding groove. A servo motor 21 is mounted on the gantry frame 16, and its drive end is connected to one end of the bidirectional lead screw 20. After the servo motor 21 is started, it drives the bidirectional lead screw 20 to rotate. Due to the thread of the bidirectional lead screw 20... In opposite directions, the two clamping arms 19 will move relative to each other or away from each other in the sliding groove, thereby clamping or releasing the steel structure cantilever support. A guide rod 17 extending along the length of the adjusting seat 5 is slidably installed on the front end face of the gantry frame 16. Multiple guide rollers 18 arranged at equal intervals are rotatably installed on the bottom surface of the guide rod 17. The guide rod 17 is connected to the clamping arm 19. When the clamping arm 19 moves, it drives the guide rod 17 to move. The guide rollers 18 roll on the surface of the steel structure cantilever support, playing a guiding and auxiliary propulsion role.

[0052] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
