Description

An anti-drop sill for elevator doors

technical field

The utility model relates to the technical field of elevators, in particular to an anti-falling sill for elevator doors.

Background technique

The elevator door is composed of door leaf, door pulley, sill, door guide rail and other components. The landing door and car door are suspended on the door guide rail by the door pulley, and the lower part is matched with the sill through the door guide shoe.

The sill is installed on the pedal part at the entrance of the landing door of the elevator shaft, and is an auxiliary guide for the movement of the door leaf. The sill is generally made of cold-drawn aluminum profiles. Although the aluminum profiles have good plasticity, their strength and rigidity are poor. In order to make aluminum The strength and rigidity of the profile can meet the needs of the sill, and the steel structure profile can be connected under the aluminum profile.

The sill is provided with a door guide groove matching the elevator door, and a slider assembly is provided at the bottom of the elevator door. The slider assembly includes a bracket fixed to the elevator door, and a door guide shoe fixed on the bracket. The door guide shoe Slide along the door guide to open and close. In the prior art, the notch of the door guide groove of the sill faces upward, and the cross-section of the notch is generally U-shaped or trapezoidal. When the notch cross-section is U-shaped, the elevator door is likely to break away from the door guide groove after the elevator door is hit. If the cross-section of the notch is trapezoidal, although the elevator door is not easy to break away from the door guide groove when the elevator door is hit, it is relatively safe to use, but it is inconvenient to install and replace on site. When the elevator door is removed, since the slider bracket and the elevator door cannot be directly separated, the elevator door needs to be slid out from the end of the sill for removal and replacement.

Utility model content

The utility model provides an anti-falling sill for an elevator door, which can prevent the elevator door from detaching from the sill under impact, and at the same time facilitate on-site installation and replacement of a slider assembly at the bottom of the elevator door.

An anti-drop sill for elevator doors, comprising a sill body, the top surface of the sill body has a door guide groove, and the door guide groove has a first side wall and a second side wall arranged oppositely , wherein the first side wall is provided with a horizontal stopper against the door guide shoe, and the second sidewall is provided with an anti-off stopper for preventing the door guide shoe from falling out.

The door guide shoe at the bottom of the elevator door extends into the door guide groove. When the elevator door is hit, the horizontal limiter limits the range of movement of the door guide shoe in the horizontal direction, and the anti-off limiter limits the vertical movement of the door guide shoe. The range of motion in the vertical direction, through the cooperation of the horizontal limiter and the anti-off limiter, prevents the door guide shoe from detaching from the door guide groove, thereby eliminating the risk of the elevator door detaching from the sill.

Preferably, the horizontal limiting member corresponds to the height of the door guide shoe, and the door guide shoe is slidably clamped between the horizontal limiting member and the second side wall.

The top of the elevator door is suspended on the door guide rail by the door pulley. The weight of the elevator door is carried by the door guide rail. The sill only guides the movement of the elevator door. The bottom of the elevator door is suspended in the door guide groove. The height corresponds to the height of the horizontal limiting member, and a guiding path for the movement of the door guide shoe is formed between the horizontal limiting member and the second side wall.

The horizontal limiter and the anti-off limiter are arranged in a height direction with a misalignment.

The height of the anti-off limiter is higher than the height of the horizontal limiter. When the elevator door is in normal operation, the position of the anti-off limiter is higher than the door guide shoe, and the height of the anti-off limiter and the door guide shoe is There is a compensation gap in the direction. When the elevator door is hit, the elevator door moves upwards in the vertical direction. After hitting the anti-off limiter, it is blocked in the door guide groove.

During the operation of the elevator door, the position of the door guide shoe will fluctuate up and down in the door guide groove, and the compensation gap is used to adapt to this fluctuation, so that the elevator door can run smoothly.

The horizontal limiting member can adopt various forms, as long as it can realize the blocking function in the horizontal direction, for example, the horizontal limiting member is a boss arranged along the length direction of the door guide groove. The section of the boss is trapezoidal, and the upper bottom of the trapezoid abuts against the door guide shoe.

There is a gap between the anti-off limiter and the first side wall for passing through the door guide shoe, and the door guide shoe enters the door guide groove through the gap, and enters the horizontal limiter and the horizontal limiter under the guidance of the trapezoidal waist. Between the second side walls, at this time, the anti-off limiting member is located on the vertical movement path of the door guide shoe, preventing the door guide shoe from breaking away from the door guide groove.

The anti-off limiter is located at the notch of the door guide groove. The anti-off limiter is a raised bar arranged along the length direction of the door guide groove.

There is a gap passing through the door guide shoe between the convex line and the first side wall, and the door guide shoe enters the door guide groove through the gap. When the floor sill needs to be replaced, the door guide shoe can be taken out from the door guide groove along the vertical direction, without the need to slide the elevator door out from the end of the floor sill for replacement, making the replacement easier.

The utility model is used for the anti-falling sill of the elevator door, has simple structure, is safe and convenient to use, can effectively prevent the elevator door from falling out of the sill, and at the same time facilitates the installation and replacement of the sill and the sliding block assembly at the bottom of the elevator door.
