Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical scheme of the utility model, and should not be regarded as the whole of the utility model or as the limitation or restriction of the technical scheme of the utility model.

[0018] Figure 1The diagram schematically shows the facade structure of the machine-room-less passenger elevator with a counterweight and rear-mounted car bottom wheels. Figure 2 The schematic diagram illustrates the planar layout of a machine-room-less passenger elevator with a rear-mounted counterweight and car bottom wheels. A machine-room-less passenger elevator with a rear-mounted counterweight and car bottom wheels arrangement is shown below. Figures 1-2 As shown, the system includes a car and a drive assembly. The left and right sides of the car are slidably connected to the inside of the hoistway through guide shoes and main guide rails. The drive assembly includes a main unit 1, a car bottom wheel 4, and several guide wheels. The main unit 1 is fixedly installed at the top of the hoistway and is also fixedly installed close to the rear side of the hoistway. The car bottom wheel 4 is fixedly installed at the bottom of the car. Several guide wheels are installed on one side of the main unit 1, and counterweight wheels 5 are installed on the other side of the main unit 1. The main unit 1 drives the car to move up and down through steel wire ropes via the guide wheels and the car bottom wheel 4.

The first guide wheel 2 is fixedly installed below the main unit 1, and the second guide wheel 3 is fixedly installed on the return rope beam 6. The return rope beam 6 is fixedly installed on one side of the car and is perpendicular to the main unit 1 and the first guide wheel 2. That is, the return rope beam 6 is fixedly installed on the left or right side of the hoistway close to the car, while the second guide wheel 3 is fixed on the return rope beam 6 along the width direction of the return rope beam 6.

[0020] It is worth noting that the aforementioned second guide wheel 3 includes a first return rope wheel 7 and a second return rope wheel 8. The edge of the first return rope wheel 7 coincides with the edge of the first guide wheel 2, and the edge of the second return rope wheel 8 coincides with the edge of the car bottom wheel 4. Specifically, grooves for winding the wire rope are provided on the first return rope wheel 7, the second return rope wheel 8, the first guide wheel 2, and the car bottom wheel 4. The groove area on the first return rope wheel 7 partially coincides with the groove area on the first guide wheel 2, so that after the wire rope passes through the first guide wheel 2, it can be directly guided from another direction by the first return rope wheel 7. Similarly, the groove area on the second return rope wheel 8 partially coincides with the groove area on the car bottom wheel 4, so that after the wire rope passes through the second return rope wheel 8, it can be directly guided from another direction by the car bottom wheel 4. This is used to control the vertical movement of the car in the hoistway. The first return rope wheel 7 and the second return rope wheel 8 are used to assist in the reversing of the wire rope return rope.

[0021] like Figure 2 As shown, the aforementioned car bottom wheel 4 includes a first car bottom wheel and a second car bottom wheel. The first car bottom wheel and the second car bottom wheel are fixedly installed at the midpoint of the left and right sides of the bottom of the car. The first car bottom wheel or the second car bottom wheel coincides with the edge of the second return rope wheel 8. That is, the second guide wheel 3 is installed on either the left or right side of the car. It only needs to be located on the same side of the car as the first guide wheel 2. There is no need to specifically limit the installation direction of the guide wheel.

[0022] The host wheel is arranged above the host 1, and the host wheel, the first guide wheel 2 and the counterweight wheel 5 are located in the same vertical section of the feed, the host 1 is fixedly arranged on the host beam, and the first guide wheel 2 is fixedly arranged below the host beam.

[0023] The first guide wheel 2 and the second guide wheel 3 are arranged to complete the reversing of the steel wire rope, so that the projection plane of the host beam and the host 1 is not above the car, that is, the host 1 and the host beam are arranged outside the car movement area in the shaft, the requirement of the top layer height of the machine roomless passenger elevator can be effectively reduced, the normal operation of the machine roomless passenger elevator is not affected, the return rope beam 6 can be arranged as a standard part, batch production can be realized, and the safety of the machine roomless passenger elevator is improved.

[0024] The technical scope of the utility model is not limited to the content in the above description, and the above embodiment can be variously deformed and modified by the person skilled in the art without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the protection scope of the utility model.
