Description

Technical Field

[0002] Elevators are common equipment in people's lives. They work by using a motor to drive the elevator car to move up and down with a rope. Traditional elevator drive wire rope winding drums are prone to technical problems such as rope falling during the process of winding the wire rope due to changes in the rope output angle, which affects the stability of the elevator's lifting and lowering. Therefore, an elevator drive motor group is needed to ensure stability when winding the rope. Utility Model Content

[0003] In view of the problems existing in the prior art, the utility model discloses an elevator car top drive motor group, the technical solution adopted is that a reel is fixedly connected to the gearbox output end of the motor group, and the two ends of the reel are respectively wound with a first rope and a second rope, the first rope extends from the top of the reel in a tangential direction and bypasses the first deflection guide wheel, the second rope extends from the bottom of the reel in a tangential direction and bypasses the second deflection guide wheel, the first deflection guide wheel includes a mounting base, the upper part of the mounting base is rotatably connected to a guide wheel mounting frame through a base rotating shaft, the upper end of the guide wheel mounting frame is rotatably mounted with a guide wheel through a guide wheel rotating shaft, and the first rope bypasses the guide wheel. The guide wheel can rotate horizontally on the mounting base with the guide wheel mounting frame, so that it can rotate with the rope output angle of the first rope, ensure stable contact between the first rope and the guide wheel, and reduce the risk of rope falling. The second deflection guide wheel has the same structure as the first deflection guide wheel, and the second deflection guide wheel and the second rope have the same effect.

[0004] The utility model also provides an elevator, including an elevator shaft frame, an elevator car, and the above-mentioned elevator car top drive motor group, the motor group is installed on the top of the elevator car, the first deflection guide wheel and the second deflection guide wheel are respectively fixedly connected to the edges of both sides of the top of the elevator car near the car guide rail, and are respectively located on the left and right sides of the reel, the first rope and the second rope are respectively passed around the first deflection guide wheel and the second deflection guide wheel and then fixedly connected to the top crossbeam on the top of the elevator shaft frame. The motor group drives the reel to achieve synchronous winding or release of the first rope and the second rope, thereby driving the elevator car to rise and fall.

[0005] Beneficial effects of the utility model: the utility model uses two ropes for pulling the elevator car, and the two ropes are wound together on a reel, so that the two ropes extend from the upper and lower positions of the reel to both sides respectively, and are wound on the deflection guide wheel respectively. The two ropes are bidirectionally discharged on the same reel, which ensures the stability of the rope discharge and reduces the number of motors used. The two deflection guide wheels can rotate horizontally, so that they can rotate with the rope discharge angle to ensure the stable contact between the rope and the guide wheel, reduce the risk of rope dropping, and increase the lifting height of the car. The whole device has a good use effect, simple structural improvement, and is easy to promote and apply. BRIEF DESCRIPTION OF THE DRAWINGS
