Description

Technical Field

[0001] This invention relates to the field of suspended platform equipment technology, and in particular to an adjustable combination counterweight for the safety wire rope of a suspended platform. Background Technology

[0002] Suspended platforms are a new type of high-altitude work equipment that can replace traditional scaffolding, reduce labor intensity, improve work efficiency, and be reusable. The use of construction suspended platforms has gradually become a trend and has been widely recognized in high-altitude operations such as exterior wall construction, curtain wall installation, insulation construction, and exterior wall maintenance and cleaning of high-rise and multi-story buildings. They can also be used in projects such as large tanks, bridges, and dams. Using suspended platforms eliminates the need for scaffolding, reducing construction costs to 28% of traditional scaffolding costs, while significantly improving work efficiency. Suspended platforms are flexible to operate, easy to move, convenient, practical, safe, and reliable.

[0003] The counterweight of the electric suspended platform is mainly responsible for the vertical function of the steel wire rope. It prevents the steel wire rope from bending during use, ensuring that the platform does not get stuck and that the platform's safety lock works properly. The counterweight is the most easily lost accessory on a construction site, bar none. It is easy to lose it after being moved a few times. Without the counterweight, when the platform moves upward, the auxiliary steel wire rope is easily pulled up by the safety lock, causing the safety lock to lose its rope-locking function and losing a safety guarantee.

[0004] Traditional suspended platforms typically have a counterweight of around 15 catties. In practice, it is usually replaced by a counterweight block, or sometimes by half a counterweight block (≥20 catties), a mortar bucket, or even a beverage bottle. The traditional safety wire rope counterweight for suspended platforms uses a bent wire rope, which is then secured with three rope clips. This method of securing the counterweight is cumbersome, and it needs to be re-secured every time the counterweight position is adjusted. In addition, the existing counterweights are of various specifications and types, making it difficult to prepare and adjust the weight. This can cause the safety lock to malfunction, thus failing to protect the lives of the workers.

[0005] Therefore, this invention proposes an adjustable combination counterweight for the safety wire rope of a suspended platform to solve the problems existing in the prior art. Summary of the Invention

[0006] To address the aforementioned problems, this invention proposes an adjustable combination counterweight for the safety wire rope of a suspended platform.

[0013] A further improvement is that the irregular groove is adapted to the handle assembly, the handle assembly includes a knob and an irregular rod, the irregular rod is connected to one end of the knob, and the irregular rod is adapted to the irregular groove.

[0014] A further improvement is that: both the key frame and the first keyway frame are provided with fastening grooves at their middle ends, and the key frame and the first keyway frame are fixed to the counterweight body by means of expansion bolts in the fastening grooves.

[0015] A further improvement is that the first keyway frame and the second keyway frame have the same structure, and the two side plates at the lower end of the first keyway frame and the second keyway frame are both used to be inserted into the side slots of the key frame. The height of the first keyway frame and the second keyway frame is higher than that of the key frame.

Example 2

[0040] according to Figure 1 , 2 As shown in Figures 3, 4, 5, and 8, this embodiment proposes an adjustable combined counterweight for the safety wire rope of a suspended platform, including a counterweight body 1 and a rope winder. Key frames 2 are provided on both sides of the top of the counterweight body 1, and first keyway frames 3 adapted to the key frames 2 are provided on both sides of the bottom of the counterweight body 1. The rope winder is installed on the counterweight body 1, and the rope winder includes a shaft plate 4 and a rope winder 5. A first protective cover 6 is connected to one end of the shaft plate 4 to protect the rope winder 5. The rope winder 5 is rotatably disposed inside the shaft plate 4. A gear 7 is rotatably disposed at one end of the shaft plate 4, and the gear 7 is connected to the rope winder 5.

[0041] A rotating shaft 8 is provided on one side of one end of the shaft plate 4, and a locking block 9 is elastically rotatable on the rotating shaft 8. A locking tooth 10 is provided on one side of the locking block 9, and the locking tooth 10 is used to lock the gear 7. A second keyway frame 11 adapted to the key frame 2 is provided below the shaft plate 4. In use, a rope winder is installed on the counterweight body 1, and the wire rope is threaded into the rope winder 5. The gear 7 is fixed by locking the gear 7 through the locking tooth 10 of the locking block 9, thereby fixing the rope winder 5 and fixing the end of the wire rope. When rotation is required, simply move the locking block 9 so that the locking tooth 10 disengages from the gear 7. At this time, the rope winder 5 can be rotated to adjust the wire rope. The tooth design facilitates precise adjustment of the upper and lower wire ropes. The fixing method is simple and can be easily extended and retracted.

[0042] The first keyway bracket 3 and the second keyway bracket 11 have the same structure, and the two side plates at the lower end of the first keyway bracket 3 and the second keyway bracket 11 are used to snap into the side slots of the key frame 2. The height of the first keyway bracket 3 and the second keyway bracket 11 is higher than that of the key frame 2. The rope winder is connected to the counterweight 1, and the counterweight 1 is connected to each other through the key frame 2 and the first keyway bracket 3 and the second keyway bracket 11. The two side plates at the lower end of the first keyway bracket 3 and the second keyway bracket 11 can be snapped into the side slots of the key frame 2, which is convenient for installation, disassembly and transfer, easy to operate, can be combined, is suitable for different installation needs, and can be installed without rope clips, resulting in high installation and disassembly efficiency.

A steel wire rope is threaded onto the winder 5, and the gear 7 is secured by the locking teeth 10 of the locking block 9, thus fixing the winder 5 and the end of the steel wire rope. To rotate the rope, simply move the locking block 9 to disengage the locking teeth 10 from the gear 7, allowing the winder 5 to be rotated to adjust the steel wire rope. The tooth design facilitates precise adjustment of the upper and lower steel wire ropes. The fixing method is simple, allowing for easy winding and unwinding, and it is highly adaptable to different environments. Furthermore, the rope winder and the counterweight body 1, as well as the counterweight bodies 1 themselves, are connected via a key frame 2 that adapts to a first keyway frame 3 and a second keyway frame 11. The locking plates on both sides of the lower end of the first keyway frame 3 and the second keyway frame 11 engage with the locking slots on both sides of the key frame 2, facilitating easy assembly, disassembly, and transfer. The operation is simple, and the rope can be combined to suit different installation needs. It requires no rope clips, offers high installation and disassembly efficiency, and is convenient to use. Meanwhile, when the two side plates at the lower end of the first keyway frame 3 or the second keyway frame 11 are inserted into the two side slots of the keyway frame 2, the positioning rod 25 is inserted into the positioning slot 27 for fixation to prevent loosening. When disassembling, simply pull the irregular knob 24 upward. The distance between one end face of the irregular knob 24 and the rotation point is greater than the distance between the lower end face and the rotation point, thereby lifting the slide rod 23 upward to remove the positioning rod 25 from the positioning slot 27 and release the fixation. This improves stability and facilitates disassembly.
