Technical Field

[0001] This utility model relates to the field of machinery, and more particularly to maintenance auxiliary devices, especially a suspended maintenance platform. Background Technology

[0002] Feeding machines are commonly used for conveying raw materials. In factory buildings, the feeding heads of these machines need to be replaced periodically. Because the feeding heads are positioned high, aerial work platforms are often required. Traditional scaffolding is time-consuming, labor-intensive, space-consuming, costly, and lacks flexibility. Current technology uses suspended platforms or similar equipment, allowing maintenance personnel to enter and ascend to a specific height to replace the feeding heads. However, existing suspended platforms suffer from structural instability, insufficient operational precision, and deficiencies in safety protection, making it difficult to efficiently and safely meet the needs of high-altitude maintenance operations. Utility Model Content

[0025] Furthermore, the guide structure is a telescopic guide rail.

[0026] Specifically, the specific structure and principle of the motor 3, transmission wheel, chain, wire rope drum, locking mechanism, electrical switch, plug-in contact switch 18, and telescopic guide rail in this utility model, as well as other aspects not described in detail, all adopt well-known solutions in the prior art, which are already understood by those skilled in the art and will not be elaborated here. For example, the plug-in contact switch 18 can be of model SEL1-A1Z P0.

[0027] The working principle of this utility model:

[0028] The suspended maintenance platform is installed on the top floor of the factory building. The top frame 1 is fixed to the top floor. In use, the motor 3 drives the second transmission wheel 5 to rotate via the first transmission wheel 13 and the chain. The second transmission wheel 5 drives the first wire rope drum 6 and the second wire rope drum 7 to rotate via the transmission shaft 4. The first wire rope drum 6 and the second wire rope drum 7 respectively drive the lifting platform 2 to the ground via the first wire rope 10 and the second wire rope. The guide rod 12 and the fixed rod 11 work together to guide the maintenance personnel to enter the lifting platform 2, or drive the lifting platform 2 to a height of 1.5-2 meters above the ground to prevent it from rising too high. Workers are trapped under platform 2. Maintenance personnel pull out ladder 20 from lifting platform 2. The inner end of ladder 20 is fixed to guardrail 22 by a buckle. Maintenance personnel climb up and down the maintenance platform via ladder 20. Then, the motor 3 drives the lifting platform 2 to a specific height. Then, the maintenance personnel manually push the locking rod 17 into the locking hole of the fixing plate 14, so that the guardrail 22, lifting platform 2 and fixing rod 11 are locked together, improving the stability of lifting platform 2. After the locking rod 17 enters the locking hole, the contact 19 disengages from the plug-in contact switch 18, so the control system can know that the locking mechanism has been locked, and the operation safety is monitored.

[0029] The lengths of the guide rod 12 and the fixed rod 11 can be increased or decreased according to the locking height required by the lifting platform 22 to ensure that the guide rod 12 and the fixed rod 11 are always fitted together.

[0030] This utility model is adapted to high-altitude operation scenarios of equipment. The lifting platform 2 is driven to rise and fall by the motor 3, the wire rope drum and multiple wire ropes, and the guide wheel and guide structure ensure the stability of operation, ensuring that the lifting platform 2 runs smoothly along the set path and improving the accuracy of operation. The guardrail 22 improves the protection capability of the maintenance platform, and the locking mechanism can improve the high-altitude stability of the lifting platform 2, reduce shaking, and ensure the safety of maintenance personnel to carry out maintenance work.
