Description

Technical Field

[0001] This utility model relates to the field of unloading platform technology, specifically to an unloading platform for construction engineering. Background Technology

[0002] During construction, unloading platforms, as core equipment for temporary material transfer, must form a stable connection with the protective frame on the outside of the building to meet the safety and efficiency requirements of high-altitude material loading and unloading. With the increasing prevalence of high-rise and super high-rise buildings, the load-bearing requirements of unloading platforms are constantly increasing, and the compression of construction cycles requires that the installation and fixing process of unloading platforms and protective frames be fast and repeatable.

[0003] In the existing technology, the installation and fixing methods of unloading platforms and protective frames are generally to use welding or multiple bolts for fixing. However, different types of protective frames need to be installed on the top and side walls of the unloading platform for different building materials. For example, for lightweight building materials (such as cement and sand), protective frames with protective nets are required, while for heavy components (such as steel structures and precast slabs), heavy-duty protective frames need to be replaced to avoid the heavy components causing compression and deformation to the protective frames. However, replacing the protective frames requires rotating multiple bolts in sequence to install and disassemble the protective frames and unloading platforms, resulting in low efficiency in replacing the protective frames and unloading platforms.

[0026] Reference Figures 2-6The installation mechanism includes an installation port 9, a first housing 10, an adjusting seat 12, a positioning mechanism, and a moving mechanism. Two installation ports 9 are provided on the platform plate 6. Two first housings 10 are fixedly installed on the bottom sidewall of the protective frame 7. The first housings 10 pass through adjacent installation ports 9 and are slidably connected to the sidewalls of the installation ports 9. Adjusting ports 11 are provided on the two opposite sidewalls of the first housings 10. The adjusting seat 12 is slidably disposed within the first housing 10. The positioning mechanism is disposed on the adjusting seat 12 for positioning the adjusting seat 12 relative to the platform plate 6. The moving mechanism is disposed on the adjusting seat 12 for driving the adjusting seat 12 to move within the first housing 10. The positioning mechanism includes an adjusting groove 13 and a positioning... The adjustment seat 12 has two opposing side walls with adjustment grooves 13. The positioning block 14 is slidably disposed in the adjustment groove 13. The relative movement mechanism is disposed between the adjustment seat 12 and the positioning block 14 to drive the two positioning blocks 14 to move relative to each other. Specifically, the operation of the relative movement mechanism can drive the two positioning blocks 14 to move relative to each other. After the first housing 10 passes through the installation port 9, the operation of the relative movement mechanism can drive the two positioning blocks 14 to move relative to each other and make the positioning blocks 14 extend out of the adjustment port 11. Thus, the platform plate 6 can be fixed by the cooperation of the protective frame 7 and the positioning block 14, thereby facilitating the installation of the protective frame 7.

[0027] Reference Figures 4-6The relative movement mechanism includes a support spring 15, a first cavity 16, a take-up roller 17, and a drive mechanism. The support spring 15 is fixedly disposed between the bottom of the adjustment groove 13 and the positioning block 14. The first cavity 16 is opened in the adjustment seat 12, and a positioning port is opened between the first cavity 16 and the adjustment groove 13. The take-up roller 17 is rotatably disposed in the first cavity 16. A steel wire rope 18 is fixedly disposed between the side wall of the take-up roller 17 and the positioning block 14, and the steel wire rope 18 passes through the positioning port. The drive mechanism is disposed on the take-up roller 17 and is used to drive the take-up roller 17 to rotate. The drive mechanism includes a first drive port 19, a second drive port 20, a drive prism 21, and a first handwheel 22. The first drive port 19 is opened on the adjustment seat 12, the second drive port 20 is opened on the take-up roller 17, and the drive prism 21 is rotatably disposed in the first housing 10. The drive prism 21 passes through the first drive port 19 and the second drive port 20, and the drive prism 21 and the second drive port 22 are connected. The side wall of the moving port 20 is slidably connected, and the first handwheel 22 is rotatably mounted on the side wall of the first housing 10. The first handwheel 22 is fixedly connected to the drive prism 21. Specifically, the rotation of the first handwheel 22 can drive the drive prism 21 to rotate. At the same time, the sliding cooperation between the drive prism 21 and the second driving port 20 drives the winding roller 17 to rotate. The rotation of the winding roller 17 pulls the wire rope 18 and the positioning block 14 to move, so that the positioning block 14 can retract into the adjustment groove 13. After the operator places the protective frame 7 on the platform plate 6, the first housing 10 can pass through the installation port 9. Then, the first handwheel 22 is released, so that the positioning block 14 can be driven out of the adjustment port 11 under the elastic force of the support spring 15. This facilitates the installation and fixation of the protective plate by clamping the platform plate 6 with the adjustment block and the protective frame 7. The protective frame 7 can be replaced by rotating the first handwheel 22, which has high replacement efficiency.

[0028] Reference Figure 3 and Figure 4 The moving mechanism includes a threaded rod 23, a second handwheel 24, and a guide rod 25. The threaded rod 23 is rotatably disposed within the first housing 10 and passes through the adjusting seat 12 via a threaded engagement. The second handwheel 24 is rotatably disposed on the side wall of the first housing 10 and is fixedly connected to the threaded rod 23. The guide rod 25 is fixedly disposed within the first housing 10 and passes through the adjusting seat 12 and is slidably connected to the adjusting seat 12. Specifically, the rotation of the second handwheel 24 can drive the threaded rod 23 to rotate, and at the same time, the threaded engagement between the threaded rod 23 and the adjusting seat 12 drives the adjusting seat 12 and the positioning block 14 to move, thereby facilitating the driving of the positioning block 14 to press against the surface of the platform plate 6, thus improving the installation stability of the protective frame 7.

[0029] Working principle: During use, the operator turns the first handwheel 22, which drives the drive prism 21 to rotate. Simultaneously, the sliding engagement between the drive prism 21 and the second drive port 20 drives the take-up roller 17 to rotate. The rotation of the take-up roller 17 pulls the wire rope 18 and the positioning block 14, causing the positioning block 14 to retract into the adjustment groove 13. After placing the protective frame 7 on the platform plate 6, the operator allows the first housing 10 to pass through the mounting port 9, and then releases the first handwheel 22. This allows the positioning block 14 to extend out of the adjustment port 11 under the elastic force of the supporting spring 15, thus facilitating the installation and fixing of the protective plate 6 by clamping the platform plate 6 through the adjustment block and the protective frame 7. Afterwards, the operator turns the second handwheel 24, which drives the threaded rod 23 to rotate. At the same time, the threaded rod 23 and the adjustment seat 12 are moved by the threaded engagement of the threaded rod 23 and the adjustment seat 12, thus facilitating the driving of the positioning block 14 to press against the surface of the platform plate 6, thereby improving the installation stability of the protective frame 7.
