[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0021] In the description of the present utility model, it should be noted that, unless otherwise specified, "multiple" means two or more; the orientations or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present utility model. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0022] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0023] Reference Figure 1 and Figure 2 The strong drive elevator structure provided by the utility model includes a car 1, a crossbeam 2 and two steel ropes 3. The crossbeam 2 is arranged in the hoistway above the car 1, and also includes two guide rails 8. The two guide rails 8 are respectively arranged on both sides of the car 1 and connected with the car 1 to slide up and down. The crossbeam 2 is fixedly connected to the top of the two guide rails 8. It also includes a support frame 9, which is arranged outside the car 1 and fixedly connected to the two guide rails 8, so as to improve the safety performance of the car 1 and enhance the stability of the structure.

[0024] Two rope end rods 4 are horizontally arranged at the bottom of the cross beam 2, and a fixed pulley 5 is respectively arranged at the bottom of the cross beam 2 at the front end of the two rope end rods 4. A motor 6 and two rollers 7 are arranged on the top of the car 1. Both rollers 7 are driven by the motor 6. Two steel wire ropes 3 pass through a fixed pulley 5 to connect a roller 7 and a rope end rod 4 respectively. The motor 6 drives the two rollers 7 to drive the steel wire rope 3 to be wound, so as to realize the lifting and lowering of the car 1. The position of the rope end rod 4 connected with the steel wire rope 3 is located on the center line of the two guide rails 8, so that the force is evenly distributed.

[0025] The two rollers 7 are symmetrically arranged, and the two rope end rods 4 are also symmetrically arranged, which can stabilize the car 1 and evenly share the weight. The two steel wire ropes 3 respectively connect a roller 7 and a rope end rod 4 on the same side, and the two steel wire ropes 3 are parallel to each other to avoid interference between the two steel wire ropes 3.

[0026] The two rollers 7 are symmetrically arranged on both sides of the motor 6, and the winding direction of the wire ropes 3 on the two rollers 7 is wound from the end of the motor 6 to the outside, which is a rope output method close to the motor 6 side. The two rollers 7 keep the output lengths of the two wire ropes 3 consistent during the winding process.

[0027] Working principle:

[0028] During the operation of the car 1, the steel wire rope 3 on the winding drum 7 is lifted and lowered by the electric motor 6. The steel wire rope 3 extending from the drum 7 is connected and fixed to the crossbeam 2 through the horizontally placed rope head rod 4 after being turned by the fixed pulley 5. The normal use of the steel wire rope 3 can be guaranteed while reducing the structural height, thus solving the problem of high top-layer height requirement of the traditional strong drive main engine.

[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
