Description

Technical Field

[0001] This utility model relates to the field of elevator equipment technology, and in particular to a machine room-less elevator host drive system structure, which is suitable for vertical elevators. Background Technology

[0002] Currently, with the rapid development of my country's social economy, multi-story buildings are widely equipped with vertical elevators. Among them, the market share of machine-room-less elevators is increasing year by year. The emergence of machine-room-less elevator technology eliminates the space occupied by elevator machine rooms, saving construction costs and making building designs more diversified. However, existing machine-room-less elevator drive systems have the following problems: Traction-type machine-room-less elevators often place the traction machine on a supporting steel beam base, resulting in a large drive unit size. The drive unit and supporting steel beam occupy a large amount of top floor space and shaft width space, reducing the actual usable space of the car. Furthermore, the overseas market often requires narrow shafts, which undoubtedly reduces the product's competitiveness. During elevator shaft construction, it is necessary to pre-embed steel structural components and pre-set load-bearing beams on the top wall of the civil engineering shaft. This leads to long construction periods, increased costs, and cumbersome construction, which is not only time-consuming and labor-intensive but also occupies a large space and results in high material waste. The existing machine-room-less drive system structure suffers from cumbersome construction, large space occupation, and inconvenient construction. Summary of the Invention

[0003] The purpose of this utility model is to provide a support architecture for the main drive system of a machine room-less elevator, which solves the problems of unreasonable traction machine layout, large space occupation, and inconvenient construction in the existing main drive system of machine room-less elevators. It optimizes the installation position of the traction machine, increases the stability of the traction machine, reduces the space occupied on the top floor, facilitates construction, and enhances the adaptability of the elevator.

[0004] The technical solution adopted by this utility model is as follows: The support structure of the machine room-less elevator host drive system includes a support frame composed of a host beam, elevator guide rails, and traction machine base. The key technical points are: the elevator guide rails are the main guide rail and counterweight guide rail at the rear of the elevator; the host beam includes a rope head beam rear side plate and a rope head beam front side plate that are supported side by side between the main guide rail and the counterweight guide rail; the rope head beam rear side plate and the rope head beam front side plate are connected and fixed by a rope head beam channel steel at one end, a reinforcing channel steel in the middle, and a rope head reinforcing rib at the other end; the traction machine base is fixed to the rear side of the main guide rail by bolts, and the traction machine base is provided with shock-absorbing rubber pads and bolts for fixing to the bottom of the traction machine; The connection between the main guide rail and the rear side plate of the rope head beam is fixed with a connecting bend plate by bolts. The connecting bend plate is equipped with a traction machine shock absorption and stabilization frame. The traction machine shock absorption and stabilization frame is composed of a sleeve-type lower connecting bracket and a sleeve-type upper connecting bracket connected together. An elastic rubber sleeve is provided between the lower connecting bracket and the upper connecting bracket. The lower connecting bracket is fixed to the traction machine by bolts, and the upper connecting bracket is fixed to the connecting bend plate by bolts. The rope head beam channel steel of the main beam is fixed to the counterweight guide rail by bolts through the connecting plate, the reinforcing plate and the guide rail pressure plate. The upper part of the main guide rail is equipped with a main guide rail bracket for connecting to the shaft wall, and the upper part of the counterweight guide rail is equipped with a counterweight guide rail bracket for connecting to the shaft wall.

[0005] The upper sleeve-type connecting bracket is an upper connecting plate with a sleeve integrally connected to the lower part, and the lower sleeve-type connecting bracket is a lower connecting plate with a sleeve integrally connected to the upper part. The sleeve of the upper sleeve-type connecting bracket is fitted onto the outside of the sleeve of the lower sleeve-type connecting bracket.

[0006] The advantages and beneficial effects of this utility model are as follows: Because this utility model uses the main guide rail, counterweight guide rail, and main beam at the rear of the elevator as the main support structure, and the main beam is assembled from the rear side plate of the rope head beam, the front side plate of the rope head beam, the rope head beam channel steel, the reinforcing channel steel, and the reinforcing ribs, a stable support frame is formed. A traction machine base with shock-absorbing pads and bolts is installed on the rear side of the main guide rail, allowing the traction machine of the main drive system to be placed on the rear side of the main guide rail. This greatly reduces the space occupied at the upper end of the machine room-less elevator shaft, facilitates construction, and also effectively fixes the traction machine, reducing vibration and noise. The system enhances the seismic resistance of the entire drive system. A traction machine vibration damping and stabilizing frame is installed via the connecting bend plate of the main beam. This frame, consisting of a sleeve-type lower connecting bracket, a sleeve-type upper connecting bracket, and an elastic rubber sleeve assembly, effectively mitigates the vibrations of the traction machine, both securing it and reducing the impact of vibrations on the car. Furthermore, the main guide rail bracket and counterweight guide rail bracket securely connect to the shaft, enhancing seismic and bending resistance. Therefore, this system optimizes the traction machine installation position, increases traction machine stability, reduces space occupied at the top floor, facilitates construction, and enhances elevator adaptability.
