Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to an aluminum alloy hoist reinforcement device. Background Technology

[0002] Elevators, as a modern vertical transportation tool, are used in various scenarios, including passenger elevators in residential and office buildings, freight elevators in factories, car elevators in automated parking garages, and home elevators for families. The design standards are different for each type of elevator. Passenger elevators require high speed and large lifting height, freight elevators require large load capacity and large area, car elevators require long length and heavy load, and home elevators are customized.

[0003] This patent is for home elevators. The national standard for home elevators stipulates that the rated load shall not be less than 400kg and the car area shall not exceed 1.6m². Home elevators are generally smaller and have lower stress strength. They need to be matched with the decoration of various homeowners. The frequency of use by a single family is also low. Therefore, they are different from public elevators in terms of design and materials.

[0004] Elevator installation can be categorized into brick-concrete shaft, steel structure shaft, or aluminum alloy shaft. Currently, for sightseeing elevators, aluminum alloy shafts are the mainstream configuration. Aluminum alloy shafts offer sufficient strength, standardized installation, and diverse surface treatments, making them suitable for most situations.

[0005] The aluminum alloy hoist structure consists of four aluminum alloy columns located at the four corners, with aluminum alloy beams on all four sides. The beams and columns are secured to each other using steel plate fasteners and screws, forming a complete aluminum alloy hoist structure. This hoist is then installed at the location where an elevator is to be installed. Typically, the four columns are fixed to the fasteners at their contact points using expansion bolts. Common locations include: the middle of a staircase, the middle of a living room, or outdoors.

[0006] This patent addresses the outdoor configuration of home elevators. Outdoor elevators typically have doorways on each floor near the exterior wall, with an aluminum alloy hoist installed on the outside. This hoist is then fixed to the exterior wall via connecting plates. A problem arises with this configuration: only the front of the hoist is fixed to the exterior wall, while the rear columns have no lateral movement. Due to the relatively low hardness of aluminum alloy and the bolted connections, lateral swaying occurs with only the front fixed position, potentially causing instability during elevator operation, especially in strong winds. The hoist would then experience lateral forces, resulting in poor structural integrity. Many manufacturers fail to install hoist reinforcement devices in this configuration. Some simply add a steel plate reinforcement around the outside of each floor, which is unsightly, resembling an artificial patch. Furthermore, the coated steel plates are prone to rusting over time, making maintenance difficult. Utility Model Content

[0007] Based on the above, the purpose of this utility model is to provide an aluminum alloy hoist reinforcement device to strengthen the interior of the elevator hoist, improve the structural performance of the entire hoist, and enhance its aesthetics.

A fourth fixing plate is provided on the side of the cantilever square tube welded component near the second fixing plate, and the fourth fixing plate is connected to the elevator shaft.

[0009] Furthermore, a reinforcing rear corner bracket is provided on the inner side of the connection position between the cantilever square tube welded component and the second fixing plate.

[0010] Furthermore, the cantilever square tube welded component includes a cantilever square tube body, a cantilever square tube reinforcing rib, a cantilever square tube welding plate, and an external reinforcing rib of the cantilever square tube.

The cantilever square tube body is welded with a reinforcing rib at the middle of one end near the outer stiffening plate of the cantilever square tube.

[0014] Furthermore, the first fixing plate includes a first fixing horizontal plate and a first fixing vertical plate, and the second elongated hole is disposed on the first fixing horizontal plate, wherein the first fixing horizontal plate and the first fixing vertical plate are perpendicular.

[0015] Furthermore, a first connecting hole is provided at the top of the middle part of the cantilever square tube body, and the third fixing plate is connected to the cantilever square tube body by bolts passing through the first connecting hole.
