In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Specifically, the present application provides a suspension system capable of emergency release of a gondola 50 or a weight upon failure of a hoist in the gondola 50 or sudden power failure or breakage of a working rope 131. Specifically, referring to fig. 1 to 2, the suspension system of an embodiment includes a suspension 10, a safety lock mechanism 20, and a lifting mechanism 30, the suspension is provided with a fastening assembly 12, the suspension is further provided with a working rope 131 and a safety rope 132 for climbing heavy objects, and both the working rope 131 and the safety rope 132 are detachably connected to the fastening assembly. Preferably, suspension 10 includes a cross member 11, and a fastening assembly 12 is secured to cross member 11. The safety lock mechanism 20 is provided on the suspension 10, and the working rope 131 and the safety rope 132 both pass through the safety lock mechanism 20. Preferably, the safety lock mechanism 20 is movably disposed on the beam 11, and the safety lock mechanism 20 is capable of movement along the suspension fork 10 toward and away from the fastener assembly 12. The safety lock mechanism 20 is used to lock or unlock the working cord 131 and the safety cord 132. The hoisting mechanism 30 is provided on the suspension 10, and is used to wind or release the force-receiving rope of the weight 131 and the safety rope 132, which bears the weight of the weight, in emergency release of the weight.

Specifically, the suspension system has an operating state in which the safety lock mechanism 20 releases the operating rope 131 from the safety rope 132, and the operating rope 131 is connected to the safety rope 132, and an emergency release state in which a heavy object (e.g., a basket) can normally ascend or descend along the operating rope 131. When the power is suddenly cut off or the rope or the working rope 131 is broken, the emergency release of the heavy object is required, when the emergency release state is realized, the safety lock mechanism 20 firstly locks the working rope 131 and the safety rope 132, then the stress rope 13 bearing the gravity of the heavy object in the working rope 131 and the safety rope 132 is released from the fastening component 12, and finally the stress rope 13 is arranged on the lifting mechanism 30 in a penetrating manner. Specifically, when power is suddenly cut off or the rope is jammed, the working rope 131 bears the weight of the weight, and the working rope 131 is the stressed rope 13. When the working rope 131 is broken, the safety rope 132 bears the weight of the heavy object, and the safety rope 132 is the stressed rope 13.

Further, in the present embodiment, a suspension system is used to raise and lower the gondola 50. Specifically, in a normal working state, the basket 50 climbs along the working rope 131 by the climbing machine disposed in the basket 50, the safety rope 132 is used to fix the basket 50 when the working rope 131 is broken, and prevent the basket 50 from falling, and the lifting mechanism 30 of the present application is only used when the climbing machine in the basket 50 fails or is suddenly powered off or is jammed or when the working rope 131 is broken, so as to perform emergency release on the basket 50. Further, the gondola 50 is generally connected with a working rope 131 and a safety rope 132. When the winch fails or is suddenly powered off, the suspension system suspends the basket 50 through the working rope 131, the working rope 131 is stressed at the moment, and the working rope 131 is a stressed rope at the moment. When the working rope 131 is broken, the suspension system suspends the basket 50 by the safety rope 132, the safety rope 132 is stressed, and the safety rope 132 is the stressed rope 13.

Further, in the suspension system under a normal operating state, the safety lock mechanism 20 does not lock the working rope 131 and the safety rope 132, and the working rope 131 and the safety rope 132 are connected to the fastening assembly 12 after passing through the safety lock mechanism 20, at this time, the fastening assembly 12 is in a stressed state, and the working rope 131 is tightened. The suspension system can be raised or lowered along the working rope 131 by a climbing machine on the gondola 50. When the climbing machine fails, the working rope 131 is jammed or broken or is suddenly powered off, so that the basket 50 stops in a half-empty state and cannot ascend or descend, the basket 50 needs to be released emergently, and the basket 50 descends to the ground to maintain the suspension system. Specifically, the emergency release process for the basket 50 is as follows: firstly, the lifting mechanism 30 is installed on the suspension frame 10, then the safety lock mechanism 20 locks the working rope 131 and the safety rope 132, and the safety lock mechanism 20 is spaced from the fastening component 12, so that the working rope 131 and the safety rope 132 between the safety lock mechanism 20 and the fastening component 12 are loosened, at this time, the safety lock mechanism 20 is in a stressed state, the fastening component 12 is in a loosened state, at this time, the stressed rope 13 bearing the gravity of the heavy object in the working rope 131 and the safety rope 132 can be disengaged from the fastening component 12, and the stressed rope 13 is arranged on the lifting mechanism 30 in a penetrating mode. Then the lifting mechanism 30 tightens the force-bearing rope 13 between the safety lock mechanism 20 and the lifting mechanism 30, at this time, the lifting mechanism 30 is in a force-bearing state, and the safety lock mechanism 20 is in a relaxed state. The safety lock mechanism 20 is then opened, causing the safety lock mechanism 20 to release the stressed cords 13. Finally, the lifting mechanism 30 releases the stressed rope 13 at a constant speed, so that the hanging basket 50 can stably descend to the ground under the action of gravity.

When the suspension system needs emergency release, the safety lock mechanism 20 is locked to enable the safety lock mechanism 20 to lock the working rope 131 and the safety rope 132, the safety lock mechanism 20 is arranged at a certain distance from the fastening assembly 12, the stress rope 13 between the safety lock mechanism 20 and the fastening assembly 12 can be loosened, the second end of the stress rope 13 can be disengaged from the fastening assembly 12, the second end of the stress rope 13 is connected to the lifting mechanism 30, the stress rope 13 between the safety lock mechanism 20 and the lifting mechanism 30 is tightened through the lifting mechanism 30, the stress rope 13 can be loosened by the safety lock mechanism 20 at the moment, and finally the lifting mechanism 30 releases the stress rope 13 at a constant speed, so that the hanging basket 50 can stably descend to the ground under the action of gravity. Compared with the traditional scheme of maintaining in the air by means of other hanging baskets 50, the suspension system realizes a more convenient and safer emergency release scheme.
