Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, and more specifically, to a detachable cantilever unloading platform with a rope fixing device. Background Technology

[0002] In the construction process, unloading platforms serve as the main passage for large-sized materials to and from the construction floors and are widely used in engineering practice. Among them, cantilevered unloading platforms are particularly common, and the installation and fixation of steel wire ropes for cantilevered unloading platforms is a key issue in their application.

[0003] According to patent document CN220621102U, this utility model discloses a conveniently installable and detachable cantilevered unloading platform, including a cantilevered steel platform, a first fixing device connected to the floor slab, and a second fixing device connected to the upper floor beam and the upper second floor beam. The first fixing device mechanically connects to the fixing bolts and pads via a U-shaped steel bar pull ring passing through a pre-reserved floor slab sleeve, thereby fixing the fixed end of the cantilevered steel platform to the floor slab. Wooden wedges are then used to plug the gap between the I-beam and the U-shaped steel bar pull ring to limit the horizontal displacement of the I-beam. The second fixing device hinges the steel wire rope of the cantilevered steel platform to the pull ring embedded in the beam end via a steel wire rope clamp. In this utility model, both the first and second fixing devices can be installed and removed by tightening bolts, facilitating the turnover of the cantilevered unloading platform, thus saving time and construction period. Furthermore, the materials of the fixing devices are recyclable and reusable, and generate virtually no waste, conforming to the concept of green construction.

[0004] Currently, the traditional application of steel wire rope installation and fixing has the following three problems:

[0005] Question 1: The steel wire rope fixing method for the cantilever unloading platform at the construction site usually uses double-eared lifting rings pre-embedded horizontally or vertically through the beam. Traditional horizontal pre-embedding through the beam requires embedding through the structure, which affects the main structure's stress. Vertical pre-embedding is close to the beam edge, and when subjected to a downward force, the concrete at the beam edge is prone to cracking, which can easily cause structural damage.

[0006] Question 2: Traditional lifting rings need to be cut after use and cannot be reused, which is not economical.

[0007] Question 3: The installation of steel wire ropes for traditional unloading platforms is quite cumbersome. When connecting the lifting ring to the inclined cable, all four buckles on the inclined cable need to be unfastened, then the cable is inserted into the lifting ring, and then the buckles are tightened. The complicated process reduces installation efficiency and wastes manpower and time.

[0008] Therefore, a rope-fixing method for cantilevered unloading platforms that is easy to install is needed to simplify the installation process, reduce structural damage, and improve the economic efficiency of use. Summary of the Invention

[0009] To overcome the aforementioned deficiencies of the prior art, this invention provides a detachable cantilever unloading platform cable fixing device. The technical problem this invention aims to solve is that: the cable fixing measures for cantilever unloading platforms on construction sites typically use double-eared lifting rings pre-embedded horizontally or vertically through beams. Traditional horizontal pre-embedding through beams requires penetrating the structure, affecting the structural load-bearing capacity; while vertical pre-embedding is too close to the beam edge, making the concrete at the beam edge prone to cracking under downward oblique forces, easily causing structural damage. Traditional lifting rings need to be cut after use and cannot be reused, resulting in poor economic efficiency. The installation of traditional unloading platform cable is also cumbersome. When connecting the lifting ring to the inclined cable, all four buckles on the inclined cable need to be unfastened before inserting it into the lifting ring and then tightening the buckles. This cumbersome process reduces installation efficiency and wastes manpower and time.

The right end of the limiting rod 44 is fixedly connected to a spiral rod 45.

The outer wall of the spiral rod 45 is threadedly connected to the inner wall of the internally threaded hole 45, and a nut 46 is threadedly connected to the right side of the outer wall of the spiral rod 45.

[0040] By inserting the fixed cylinder 31 into the interior of the PPR cylindrical outer shell 22, and then shaking the rocker 335 to drive the bidirectional threaded rod 336 to rotate, the two sliders 338 drive the connecting block 339 and the clamping plate 3303 to move towards or away from each other. At the same time, the two connecting blocks 3302 drive the two sliding sleeves 3301 to slide on the outer wall of the sliding rod 330, making the movement of the clamping plate 3303 more stable. This allows the clamping plate 3303 to move closer to or away from the outer wall of the concrete layer 1, thus realizing the installation and fixation of the disassembly structure 3. Then, the upper lifting ring 43 is put into the outer wall of the J-shaped limiting clip 38, and then the insertion rod 346 is inserted into the inner wall of the pin hole 345 and shaken, thereby driving the connecting sleeve 343 to move. The rotation of the fixed cylinder 342 causes the internal threaded cylinder 341 to rotate on the inner wall of the bearing 344. Simultaneously, the rotation of the internal threaded cylinder 341 causes the fixed screw 37 to rotate and move. At the same time, the outer wall of the fixed screw 35 rotates on the inner wall of the internal threaded groove 24, achieving bolt fixation. While rotating, the J-shaped limiting clip 38 also rotates and eventually stops on the inner wall of the annular groove 333, thus fixing the lifting ring 43. By inserting the limiting rod 44 into the inner wall of the lower lifting ring 43 and inserting the spiral rod 45 into the inner wall of the internal threaded hole, and then screwing the nut 46 onto the outer wall of the spiral rod 45, the lifting ring 43 is installed on the unloading platform 5.

[0041] like Figure 9As shown, the stabilizing structure 6 includes an inner and outer threaded cylinder 61. A second inner threaded hole, extending to the bottom, is provided on the top rear side of the main beam of the unloading platform 5.

The outer wall of the J-shaped stabilizing rod 65 is movably connected to the inner wall of the lowest J-shaped limiting clamp 38. A connecting plate 62 is fixedly connected to the bottom of the inner and outer threaded cylinder 61. A T-shaped block 63 is fixedly connected to the rear side of the connecting plate 62. The top of the T-shaped block 63 is movably connected to the bottom of the lowest concrete layer 1.

[0042] By screwing the inner and outer threaded cylinder 61 into the inner wall of the inner threaded hole 2, and then screwing the spiral rod 2 64 into the inner wall of the inner and outer threaded cylinder 61, the J-shaped stabilizing clamp rod 65 is inserted from below into the inner wall of the first J-shaped limiting clamp 38 from bottom to top. Then, under the action of the connecting plate 62, the T-shaped block 63 supports the bottom of the first concrete template 11 from bottom to top, thereby realizing the installation of the unloading platform 5.

[0043] The working principle of this invention is as follows: The fixed cylinder 31 is inserted into the interior of the PPR cylindrical outer shell 22. The rocker 335 is then cranked to rotate the bidirectional threaded rod 336, causing the two sliders 338 to move the connecting block 339 and the clamping plate 3303 towards or away from each other. Simultaneously, the two connecting blocks 3302 cause the two sliding sleeves 3301 to slide on the outer wall of the sliding rod 330, making the clamping plate 3303 more stable during movement. This allows the clamping plate 3303 to move closer to or further away from the outer wall of the concrete layer 1, thus achieving the installation and fixation of the disassembly structure 3. The upper lifting ring 43 is then fitted onto the outer wall of the J-shaped limiting clip 38. The insertion rod 346 is then inserted into the inner wall of the pin hole 345 and cranked, thereby driving the connecting sleeve 3... 43 rotates and drives the fixed cylinder 342 to rotate. The rotation of the fixed cylinder 342 causes the internal threaded cylinder 341 to rotate on the inner wall of the bearing 344. While the internal threaded cylinder 341 rotates, it drives the fixed screw 37 to rotate and move. At the same time, the outer wall of the fixed screw 35 will rotate on the inner wall of the internal threaded groove 24 to achieve bolt fixation. While rotating, the J-shaped limit clip 38 also rotates and finally stops on the inner wall of the annular groove 333 to fix the lifting ring 43. By inserting the limit rod 44 into the inner wall of the lower lifting ring 43 and inserting the screw rod 45 into the inner wall of the internal threaded hole 1, and then screwing the nut 46 onto the outer wall of the screw rod 45, the lifting ring 43 is installed on the unloading platform 5.

[0044] By screwing the inner and outer threaded cylinder 61 into the inner wall of the inner threaded hole 2, and then screwing the spiral rod 2 64 into the inner wall of the inner and outer threaded cylinder 61, the J-shaped stabilizing clamp rod 65 is inserted from below into the inner wall of the first J-shaped limiting clamp 38 from bottom to top. Then, under the action of the connecting plate 62, the T-shaped block 63 supports the bottom of the first concrete template 11 from bottom to top, thereby realizing the installation of the unloading platform 5.
