Description

Technical Field

[0001] This utility model relates to the field of beam technology, and in particular to a machine room-less elevator upper beam device. Background Technology

[0002] The upper beam of a machine-room-less elevator is a crucial component of the elevator car system, undertaking multiple functions including fixing the car, transferring loads, enhancing structural rigidity, and ensuring safety. As the main support component at the top of the car, the upper beam, connected to the guide rails, transfers the car's weight to the guide rail system, ensuring the car's stability during operation. Simultaneously, during elevator operation, the upper beam must withstand the impact forces from the car, the load, and braking, distributing them evenly to the guide rails and hoistway structure to prevent localized stress concentration. Furthermore, a safety clamp trigger device is installed on the upper beam; in the event of elevator overspeed or loss of control, the safety clamp will activate. The elevator uses the interaction between the upper crossbeam and the guide rails to bring the car to an emergency stop, ensuring passenger safety. However, the existing upper crossbeam has a fixed length, but during actual construction, the distance between the guide rails may be incorrect due to construction deviations, resulting in gaps between the guide rails and the upper crossbeam, which reduces safety during use. At the same time, the existing connection between the upper crossbeam and the elevator is a rigid connection, which will generate low-frequency noise due to vibration during operation. Low-frequency noise will affect passenger comfort, and long-term low-frequency noise will also cause certain damage to the building. In view of this, this utility model is proposed. Summary of the Invention

[0003] To overcome the technical defects of existing technologies, this utility model provides a machine room-less elevator upper beam device with adjustable length and vibration buffering effect. The position of the connecting parts on the fixed beam can be adjusted by adjusting the components, thereby adjusting the distance between the connecting parts. This allows the overall length of the structure to be adjusted according to the distance between the guide rails, which facilitates user installation and improves safety during use. At the same time, the external elevator is installed on this structure through the buffer connecting components, which can buffer vibration, thereby reducing noise caused by vibration and improving passenger comfort.

[0004] The technical solution adopted by this utility model is as follows: it includes a fixed crossbeam and a connector. The connector is slidably engaged at both ends of the fixed crossbeam and is connected to an external guide rail. An adjustment component is installed on the connector and is connected to the fixed crossbeam. A sliding groove is provided at the lower part of the fixed crossbeam, and a buffer connection component is slidably engaged in the sliding groove. The upper part of the buffer connection component is connected to the lower inner end of the fixed crossbeam, and the external elevator is connected to the buffer connection component. In use, the structure is first placed at the installation location, and then the position of the connector on the fixed crossbeam is adjusted by the adjustment component so that the connecting ring contacts the external guide rail. Then, the structure is connected to the external guide rail to complete the installation. During use, the buffer connection component can buffer the vibration generated by the external elevator, thereby reducing the generation of low-frequency noise and improving passenger comfort.

[0005] Preferably, to facilitate the rotation of the drive shaft, a cross-shaped groove is provided on one side of the upper end of the connector. The adjusting component includes a drive shaft, one end of which is rotatably engaged with the upper end of the connector through the cross-shaped groove. A hexagonal drive bolt is fixedly installed at the upper end of the drive shaft, and a drive bevel gear is fixedly installed at the lower end of the drive shaft. The drive bevel gear is located inside the connector.

[0006] Preferably, in order to rotatably engage the adjusting threaded rod inside the connector and simultaneously drive the adjusting threaded rod to rotate, the adjusting assembly further includes a partition plate. The partition plate is fixedly installed inside the connector and is located on one side of the drive shaft. A cross-shaped engaging groove is provided in the middle of the partition plate. The adjusting threaded rod is rotatably engaged in the engaging groove. A driven bevel gear is fixedly installed at one end of the adjusting threaded rod, and the driven bevel gear meshes with the driving bevel gear.

[0007] Preferably, in order to move the connecting member on the fixed crossbeam and thereby adjust the overall length of the structure, a connecting plate is threaded onto the adjusting threaded rod, and the connecting plate is fixedly installed at one end inside the fixed crossbeam.

[0008] Preferably, in order to connect this structure to the external guide rail, a connecting ring is fixedly installed at one end of the connector, a connecting hole is opened on the outer side of the connecting ring, a connecting bolt is provided on the connecting hole, and the connecting bolt is threadedly connected to the external guide rail.

[0009] Preferably, in order to buffer vibration and reduce the generation of low-frequency noise, the buffer connection assembly includes a mounting member. The mounting member is I-shaped and is slidably engaged in the sliding groove. The upper and lower ends of the mounting member are located on the inner and outer parts of the fixed crossbeam, respectively. A buffer pad is fixedly installed on the outer side of the middle section of the mounting member, and the buffer pad is in contact with the sliding groove. Buffer pressure cylinders are fixedly installed in an array on both sides of the upper and lower ends of the mounting member. The lower end of the buffer pressure cylinder is fixedly installed on the lower inner end of the fixed crossbeam.

[0010] The beneficial effects of this utility model are: by adjusting the components, the position of the connecting parts on the fixed crossbeam can be adjusted, thereby adjusting the distance between the connecting parts, so that the overall length of this structure can be adjusted according to the distance between the guide rails, which facilitates the installation by the user and improves the safety during use. At the same time, by using the buffer connecting components to install the external elevator on this structure, the buffer connecting components can buffer the vibration, thereby reducing the noise caused by the vibration and improving the comfort of passengers.
