Description

An elevator door sill

technical field

The utility model relates to the technical field of elevators, in particular to an elevator door sill.

Background technique

The elevator door sill is an important part of the elevator. It usually includes a sill body that guides the elevator door to run, supports the passage of passengers and goods, and a sill bracket for installing and fixing the sill body. According to different use positions, elevator door sills are usually divided into car door sills (installed on the elevator car) and landing door sills (installed at the elevator entrance of each floor).

Commonly used sills for freight elevators are generally divided into cast iron sills and aluminum alloy sills according to different sill materials.

The structure of the cast iron sill is shown in Figure 1, including: the cast iron sill body 1 and the C-shaped bent sill installation bracket 2, wherein the cast iron sill body adopts a solid steel sill, which is heavy in weight and uses more materials, reducing the cost. It is taller and bears a larger load, and is usually used on freight elevators with larger loads (more than 3 tons).

The structure of the aluminum alloy sill is shown in Figure 2, including the aluminum profile sill body 3 and the C-shaped bent sill mounting bracket 2, wherein the aluminum alloy sill body is made of aluminum alloy profiles, and the wall thickness is relatively thick compared to the cast iron sill. Uniform and thin, light weight, fewer materials, lower cost, good surface quality, but because the aluminum alloy itself is slightly weaker than steel, it is usually only used in passenger elevators with small loads (passenger and freight elevators of 2 tons and below) ), which are rarely used on larger freight elevators of 3 tons and above.

Preferably, the top surface of the partition frame is flush with the top surface of each extension part. The top surface of the partition frame and the top surfaces of each extension serve as the upper surface of the sill body.

Preferably, the sill body is made of aluminum alloy. Reduce the weight and cost of the sill body, and have better surface quality.

Compared with the prior art, the utility model has the following advantages:

(1) The structure is simple, the amount of aluminum alloy is less, and it is lighter in weight and lower in cost than cast iron sills, and has better surface quality.

(2) The load-bearing capacity of the aluminum alloy sill body is improved through the sill bracket, which can replace the cast iron sill to meet the needs of heavy-duty elevators.
