The working process and the specific implementation mode of the hoisting elevator are as follows:

as shown in fig. 2, the present invention is further described,

in the specific installation process of the elevator shaft, the top cross beam is fixed at the top end of the elevator shaft, and 4 fixed steel cables and 4 winding steel cables are put down; firstly, a fixed steel cable passes through 8 wire guides on the car, and the tail end of the fixed steel cable is fixed on a fixed base, so that the car is connected in series with 4 fixed steel cables; then pass 4 winding steel cables through the wire guide at car top back winding to two hoist motor spools of car bottom, because another winding of hoist steel cable is on two hoist motor spools of top crossbeam, whole car is drawn by four hoist steel cables completely, when hoist motor circular telegram work winding/release hoist steel cable, the car is along 4 fixed steel cables up-and-down motion under the drawing of hoist steel cable. When the elevator reaches a required floor, the hoisting motor stops working to enable the elevator car to be static for people to come in and go out until the elevator ascending/descending switch is pressed down again, and the actions are repeated to realize the ascending and descending functions of the elevator.

In the design and embodiment disclosed here, items not explicitly disclosed, such as operating conditions and operating conditions, various parameters, and the size, weight, volume, and the like of the components, are assumed to be values that can be easily assumed by a person skilled in the art without departing from the scope of the general practice of the person skilled in the art.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution and the inventive concept of the present invention within the technical scope of the present invention.

The invention has the following beneficial effects:

1. adopt fixed steel cable to make the ascending/descending guide rail/the guide rope of car, can need not the elevartor shaft installation, have extremely strong environmental suitability and installation and deploy flexibility, need not set up special computer lab at the top, also need not redundant designs such as counter weight, higher reliability can be brought in more succinct design, and the installation is swift, and is with low costs.

2. The power of going up and down of elevator both can be provided by two hoist motor on the car chassis, also can be provided by two hoist motor on the crossbeam of top, and two power sources, even if arbitrary power supply breaks down, another power supply still can guarantee normally to go up the line down, has reduced the influence that power trouble normally operated to the elevator, has prevented effectively that the elevator from in the air because of power trouble card, neither makes things convenient for withdrawing of personnel in the car, also makes things convenient for maintainer half-air to overhaul, has effectively reduced each item risk when the elevator trouble.

3. Compared with the traditional elevator, the winding type elevator has four winding steel cables to pull the elevator car to move up and down, and can still normally run under the traction of the three winding steel cables even if one winding steel cable is broken; even if two winding steel cables in the opposite angle positions are simultaneously broken, the other pair of winding steel cables in the opposite angle positions can still pull the lift car to move up and down under the assistance of the four fixed steel cables and the wire guide; even two hoisting steel cables at the same side are simultaneously broken, when the car inclines to one side, the fixed steel cables can restrain the inclination angle of the car under the cooperation of the wire guide, so that the inclination angle is prevented from being too large, and the car can descend to the ground at a safe and controllable inclination angle; even more when three hoist steel cables break simultaneously, only remaining one hoist steel cable still can carry out inclination restraint to the car under the cooperation of four fixed steel cables and wire guide, prevents that inclination is too big, lets the car still can be with safe controllable inclination down to ground.

4. Compared with the traditional elevator, the hoisting type elevator adopts the hoisting motors as power, the combined application of the hoisting motors is realized by the plurality of hoisting motors under the matching of the synchronous chains and the hoisting steel cables, two adjacent hoisting motors are connected together by the synchronous links, and an upper group and a lower group of power sources are formed; even if a certain hoisting motor fails and stops working, the adjacent hoisting motors can be automatically locked under the coordination of the synchronous chains, only the other group of hoisting motors is reserved for normal working, and the ascending and descending of the elevator are not influenced; the upper and lower groups of hoisting motors realize the functions of power redundancy and safety redundancy, and the speed and load multiplication is realized when the two groups of power sources are superposed.

5. Four hoist steel cables are as power steel cable, both can share the atress, have safe redundancy again concurrently, even if a certain/many hoist steel cable fracture, as long as not four whole fracture, the homoenergetic guarantees that the car does not fall down fast out of control, has better security.

6. The plurality of hoisting motors can be controlled in a wired/wireless mode through one controller, so that the whole elevator control system is simplified into a mode that only the starting and stopping of the motors are controlled, and the design of the elevator control system is simplified.

7. Compare traditional elevator, the hoist and mount elevator has very big advantage because of simple structure, later maintenance cost, uses the maintenance cost to be only the fraction of traditional elevator.
