Contents of the invention

The main purpose of the present invention is to provide a machine room-less elevator system to improve the shortcomings of traditional machine rooms occupying floor space and increasing construction costs.

Another object of the present invention is to place the driving tractor at an appropriate position in the hoistway, completely avoiding the passage of the elevator car and counterweight lifting and sliding, and the fixed height can be elastically configured.

In order to achieve the above object, the present invention provides a machine room-less elevator system, comprising: a well defined by a structural wall, on which a car guide rail and a counterweight guide rail are arranged; a car that slides up and down along the car guide rail; Sliding counterweight; at least one steel cable anchored at both ends, used to suspend the carriage and counterweight; driving tractor, located between the carriage and the hoistway wall outside the counterweight lifting passage, controlled and linked The carriage and the counterweight; the system also includes a support for fixing the driving tractor and an elevator control panel for controlling the traction; the steering wheel on the carriage side is arranged on the top of the support at an appropriate deflection angle; the steering on the counterweight side The wheels are arranged on the top of the track support beam at an appropriate deflection angle, so that the tractor can drive the steel cable and drive the carriage and counterweight at a smooth angle.

Detailed ways

As shown in Fig. 1 and Fig. 2, the machine-room-less elevator system of the present invention comprises: a hoistway 1 defined by the structure wall, on which the hoistway 1 wall is provided with a carriage guide rail 4 and a counterweight guide rail 6, and the carriage guide rail 4 is connected with a matching The top of the heavy guide rail 6 is fixed on the wall of the hoistway 1 by horizontally arranged support beams 7, 7'; a carriage 3 that slides up and down along the carriage guide rail 4 has at least one carriage pulley 13 at the bottom, or usually a pair of carriage pulleys 13, 13'; a counterweight 5 sliding up and down along the counterweight guide rail 6, with a counterweight pulley 12 on the top; at least one flat steel cable 14 anchored at both ends, or usually three in parallel, suspending the carriage 3 and the counterweight 5; a driving tractor 2, located between the wall of the well 1 outside the compartment 3 and the counterweight 5 lifting passage, controlled to drive the cable 14 and link the compartment 3 and the counterweight 5. Wherein, a support member 8 is included on the wall of the hoistway 1, which is used to fix the drive traction machine 2, and an elevator control panel 9 for controlling the traction machine 2; Top; a counterweight side steering wheel 11 is arranged on the top of the track support beam 7 with an appropriate deflection angle, so that the tractor 2 drives the steel cable 14, and can drive the carriage 3 and the counterweight 5 at a smooth angle.

As shown in Figure 3, in order to effectively utilize the cross-sectional area of the hoistway 1, the present invention uses a thin PM motor as the power source to drive the tractor 2, and the support 8 that fixes the tractor 2 is fixed on the carriage 3 and the counterweight 5 for lifting. On the wall of the hoistway 1 outside the passage, and through other auxiliary beams, it is combined with the compartment guide rail 4 or the counterweight guide rail 6, etc. The drive tractor 2 is fixed below the support 8, and the elevator control panel 9 can be fixed on the space above the drive tractor 2 or the support 8 in the space below the drive tractor 2, or the two can be fixed on the support 8 with the same structure , so that the control panel 9 can be connected and controlled with the traction machine 2 with very short wires.

In the present invention, the driving tractor 2 is installed at the first-order position on the top floor of the hoistway 1, preferably within 2M below the floor surface of the top floor, and can be flexibly configured according to the characteristics of the building. The motor of the tractor 2 is a cantilever structure, that is, the cable driving wheel 2a is pivotally arranged outside the motor body. In the embodiment shown in Figures 1 and 2, one end of the steel cable 14 is anchored at the C end of the track support beam 7', extends downward from the C end to bypass the carriage pulley 13, and then extends upward to bypass the carriage side The steering wheel 10 extends downwards to bypass the drive wheel 2a of the tractor 2, then extends upwards to bypass the counterweight side steering wheel 11, then extends downwards to bypass the counterweight pulley 12, and then extends upwards to stop at the track support beam 7 on the W side. In the present invention, the driving traction machine 2 is driven under the steering wheel 10 on the side of the car at the load end, and the direction of the force is upward and driven in the direction of anti-gravity, so that when the elevator is carrying the load, the tension between the steel cables 14 cancels each other up and down. As an internal force, it is borne by the structure itself. And because the counterweight side steering wheel 11 and the terminal W of the steel cable 14 are arranged on the support beam 7 above the guide rail, most of the weight is supported by the counterweight side guide rail 6, so the longitudinal force of the support member 8 is greatly weakened, Therefore, whether it is fixed on the wall of the hoistway 1 or on the guide rail 4 of the carriage, the reliability of the fixing strength can be improved. In addition, as shown in Figure 4, since the driving tractor 2 is a thin motor, in order to resist the torque generated during suspension, a plurality of axial vibration-absorbing elements 21 are provided on the lower support 81 of the tractor 2, and the upper support A plurality of radial vibration-absorbing elements 22 are arranged on the piece 82 to make the anti-vibration structure of the elevator three-dimensional to absorb multi-directional vibrations.

The machine room-less elevator system of the present invention has the following effects:

(1) It can not only save the construction cost of the traditional computer room, but also save the space occupied by the computer room, and at the same time make the design of the building unrestricted.

(2) Provide multiple replaceable height positions of the driving tractors in the hoistway, which can be flexibly configured according to the characteristics of the building.

(3) The thin PM motor is adopted, and due to its high efficiency, the power of the motor can be reduced by 2 levels compared with the current standard elevator (TK type), achieving an energy-saving green design.

(4) Since the steering wheel 10 on the side of the carriage and the driving tractor 2 are fixed on the same support member 8, the external force of the steel cable 14 is mutually offset into an internal force, which is borne by the structure itself, whether it is fixed on the well wall or the carriage guide rail, Both can improve the reliability of the fixing strength.

(5) Because the driving tractor 2 belongs to a thin motor, in order to resist the torque generated during suspension, the vibration-absorbing element 21 in the axial direction is arranged below it, and the vibration-absorbing element 22 in the radial direction is arranged above it, and the anti-vibration structure is three-dimensional, which can Absorbs multiple vibrations.
