Description

Technical Field

[0001] This utility model relates to an elevator host structure reinforcement device, specifically an anti-sway device for a machine room-less passenger elevator host. Background Technology

[0002] The traction machine of an elevator is the main device that drives the elevator to move up and down. In machine-room-less elevators, the traction machine needs to be installed on the load-bearing beam at the top of the shaft. The traction machine is mainly fixed to the load-bearing beam through its base. However, the height of the traction sheave of the traction machine is usually higher than its fixed position, which makes its stress structure higher than its fixed center of gravity. Under certain operating conditions, this will cause the traction machine to shake, resulting in abnormal noise and accelerating the wear of consumable parts, affecting the comfort of elevator operation. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings in the existing technology and to provide a machine room-less passenger elevator main unit anti-sway device.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: The main unit anti-sway device includes a wall-mounted bracket, a main unit connecting bracket, and a main unit connecting rod. The traction main unit is fixedly installed on the load-bearing beam and set near the wall of the hoistway. A hoistway ring beam is set on the wall of the hoistway. The traction main unit is fixedly connected to the hoistway ring beam through the main unit anti-sway device. The wall-mounted bracket is fixed to the hoistway ring beam, and the main unit connecting bracket is connected to the wall-mounted bracket. The main unit connecting rod laterally pulls and fixes the main unit connecting bracket and the traction main unit. The wall-mounted bracket is a fixed installation position set on the vertical foundation. The main unit connecting bracket can be adjusted and set to correspond to the installation space on the traction main unit. The main unit connecting rod plays a lateral fixing and pulling role, which can effectively limit the lateral jump of the main unit, effectively reduce the sway of the main unit, reduce noise and wear, and extend the structural life.

[0005] Furthermore, the wall-mounted bracket includes a right-angled strip, fixing holes, connecting holes, and reinforcing ribs. The right-angled strip is a strip-shaped metal plate with a right-angle structure. One side has a fixing hole for fixing to the shaft ring beam, and the other side has a connecting hole for connecting to the main unit's connecting frame. Reinforcing ribs are welded and fixed to the inner side of the right-angled strip. The wall-mounted bracket has sufficient installation distance in the lateral direction. Both the fixing holes and connecting holes have adjustable lengths, allowing for distance adjustment within a certain range. The structure is reinforced, ensuring stable installation and use.

[0006] Furthermore, the main unit connection frame includes a right-angle member, reinforcing ribs, connecting holes, and adjustment mounting holes. The right-angle member is a rigid metal component with a right-angle structure, and reinforcing ribs are fixedly welded to its inner right-angle side. Connecting holes and adjustment mounting holes are respectively provided on the two right-angle faces. The connecting holes of the main unit connection frame correspond to the connecting holes of the wall-mounted bracket, and the main unit connection rod is connected to the adjustment mounting hole. The connecting holes and adjustment mounting holes on the main unit connection frame are also elongated oval holes, allowing for good adjustment freedom and adjustment according to the specific positions of the holes on the main unit.

[0007] Furthermore, the main unit connecting rod includes a screw, a bracket screw connector, and a main unit screw connector. One end of the screw is fixedly connected to the main unit connecting frame via the bracket screw connector, and the other end is fixedly connected to the fixing lug on the main unit via the main unit screw connector. The screw is the main rigid connection structure and also has a distance adjustment function, with a large adjustable range to adapt to different installation distances.

[0008] Furthermore, shock-absorbing pads are sleeved between the main unit screw connections. The shock-absorbing pads are fitted into the inner holes of the fixing ears and are sleeved on the screws. The shock-absorbing pads can reduce friction, reduce noise generated by vibration, and improve comfort.

[0009] Compared with the prior art, this utility model has the following advantages and effects: This design is a lateral structural reinforcement device for the host, which can effectively limit the lateral sway of the host, reduce noise, reduce structural wear, extend structural life, and improve riding comfort.
