At present, the known freight elevator is mainly of a traction type mechanism, and the elevator mainly comprises a traction part, a guide part, a car, a counterweight and an electric control part. When the elevator works, the traction mechanism undertakes a lifting task, namely the traction wheel drives the steel wire rope to do reciprocating motion, so that the car and the counterweight at the two ends of the steel wire rope do vertical opposite motion under the limitation of respective guide mechanisms, the electric appliance control mechanism controls the car to ascend or descend as required and stop at a specified floor according to a received instruction, and thus the purpose of vertical transportation of goods is realized when the car is loaded with the goods. Due to the development of society, the development of villages, towns, private enterprises and individual enterprises is strong, the increasing of factory buildings of multi-storey buildings greatly requires the installation of freight elevators, and a simple elevator with an electric hoist replacing a lifting mechanism is produced.

The first embodiment is as follows:

as shown in fig. 1 and 2, the safe elevator of this embodiment includes an elevator car 1 and an electric block disposed above the elevator car 1, a partition plate 3 is disposed in a winding drum 2 of the electric block, the partition plate 3 is coaxially fixed in the middle of an output shaft 4 of the winding drum, the output shafts 4 on both sides of the partition plate 3 are respectively connected with a first steel wire rope 5 and a second steel wire rope 6, the lower end of the first steel wire rope 5 is connected with the upper end of the elevator car 1, the lower end of the second steel wire rope 6 is connected with a spring 7, and the lower end of the spring 7 is connected with the lower portion of the elevator car. It should be noted that the spring 7 is normally in tension, but its tension is preferably less than one third of the spring deflection length, ensuring that the combination of the second rope 6 and the spring 7 has a pulling effect on the elevator car 1, while not affecting the amount of elastic deformation of the spring 7 that is accidentally used for damping.

In this embodiment, it should be further explained that the lower end of the spring 7 is connected to the bottom of the elevator car 1 after passing through the side wall of the elevator car 1. The bottom of the second steel wire rope 6 provided with the spring is connected with the upper end of the spring, and the lower end of the spring is connected with the bottom of the elevator car 1, so that the part provided with the spring has a larger telescopic space (thereby solving the problem that the floor on which the electric lifting hoist is suspended is high). It is further explained that the balance weight can be arranged in the side wall and the bottom plate of the elevator car 1, and then the spring penetrates through the side wall of the elevator car 1 and then is connected to the bottom of the balance weight in the side wall, so that the original connecting structure is not influenced, and the balance performance is better.

The two groups of steel wire ropes can independently bear the total weight of the elevator lifting platform and objects (namely people and goods) carried by the elevator lifting platform. But in practice the second wire 6 also bears 1/5-1/4 weight due to the action of the spring. Therefore, no matter which group of the steel ropes is broken in the operation (lifting), the other group of the steel ropes which run coordinately, independently and synchronously can continuously bear the lifting elevator.

The utility model discloses simple structure, the design has two sets of independent wire ropes of first wire rope 5 and second wire rope 6, these two sets of independent wire ropes can coordinate under electric block's traction, it is independent, synchronous operation (lift), but not mutual traction, each group of wire rope can both independently bear elevator lift platform and the total weight of the object of carrying (being people and goods), if there is a set of wire rope disconnected, then another group coordinates, it is independent, synchronous operation's wire rope can continue to bear elevator, from the theoretical analysis, the possibility that two sets of wire ropes are disconnected simultaneously is nearly zero, so it is very safe; the partition plate can prevent the first steel wire rope 5 and the second steel wire rope 6 from being wound together in the winding process, and smooth winding and unwinding of the two groups of steel wire ropes can be guaranteed. The utility model discloses suspend two sets of independent wire rope in midair on same electric block to furthest's saving elevator cost, wherein a set of wire rope installs the spring, and the spring plays the concerted action, enables two sets of independent wire rope synchronous, coordinated operation to avoid two sets of wire rope of independent operation to cause the phenomenon that wire rope idled or twined in disorder on electric lift block's reel because of can not synchronous operation.
