A shaft top layer arrangement structure of a machine room-less elevator

Abstract

The invention relates to the technical field of elevator manufacturing, in particular to an arrangement structure for the shaft top layer of a machine-room-less elevator, including a main girder frame and an auxiliary girder frame. The installation groove, the main installation groove is provided with a horizontal traction drive main engine, the rotating shaft of the horizontal traction driving main engine is parallel to the main beam frame, a traction sheave is connected to the rotating shaft, and a counterweight device is provided under the traction sheave. The weight device is equipped with a left counterweight reversing sheave and a right counterweight reversing sheave, and the main girder is provided with a left counterweight rope end set and a right counterweight rope end set, and the hoistway is located on the front side of the traction wheel In the area on one side of the wall, there are also two front and rear car floor anti-sheaves, which are respectively located on the front and rear sides of the bottom of the car and are used to cooperate with the traction sheave and whose axial direction is parallel to the axial direction of the traction sheave. Just above the front end of the anti-rope pulley on the front car bottom, there is a car rope head group installed on the sub-beam frame. High structural strength, safe and stable operation and can greatly save space.

Description

technical field [0001] The invention relates to the technical field of elevator manufacturing, in particular to a hoistway top layer arrangement structure of a machine room-less elevator. Background technique [0002] The structure of the top floor of the hoistway is very important for machine room-less elevators. It is the most important part related to the rational layout and space optimization of the entire elevator. However, the machine room with large tonnage and high speed has a large volume and takes up a lot of space. , The design of the corresponding main engine bearing platform should be more reliable and firm, and it can carry more weight and force. This will inevitably greatly increase the space on the top floor of the machine room, affect the overall arrangement of the elevator, and affect the area of ​​the car, resulting in waste of space. The effective area of ​​the car is reduced, and at the same time, the complex structure requires high processing technology...

[0002] The structure of the top floor of the hoistway is very important for machine room-less elevators. It is the most important part related to the rational layout and space optimization of the entire elevator. However, the machine room with large tonnage and high speed has a large volume and takes up a lot of space. , The design of the corresponding main engine bearing platform should be more reliable and firm, and it can carry more weight and force. This will inevitably greatly increase the space on the top floor of the machine room, affect the overall arrangement of the elevator, and affect the area of ​​the car, resulting in waste of space. The effective area of ​​the car is reduced, and at the same time, the complex structure requires high processing technology, and the installation requirements and difficulty are very high. If the deviation angle of the main engine is too large, it is easy to cause the wire rope to fall out of the groove, which is a great safety hazard
