Problems solved by technology

However, because the depth of the elevator shaft in the building is restricted by various factors, it cannot meet the depth requirements of the pit, especially when installing elevators in old residential areas. Due to the large number of pipes buried underground, the pipe transfer process is cumbersome, and the pit cannot be dug deep to reach more than 0.79m. depth

Embodiment Construction

[0053] The height-adjustable toe guard device of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0054] Such as figure 1 , Figure 7 As shown, a height-adjustable toe guard device includes: a three-level toe guard installed on the bottom of the sill bracket 8 and slidingly folded, and a locking device for maintaining each level of toe guard in a folded state.

[0055] Such as figure 1 As shown, the three-level toe guard includes: when deployed along the direction of gravity, from top to bottom, the first-level toe-guard 1a fixed on the bottom of the sill bracket 8, the middle toe-guard 1b slidingly matched with the first-level toe-guard 1a, and the The middle toe guard 1b is slidably matched with the final toe guard 1c, and the bottom of the last toe guard 1c is provided with a linkage 21 that drives the middle toe guard 1b into a folded state.

[0056] The opposite sides of the toe guards at all levels are provided w...

Abstract

The invention discloses a height-adjustable toe guard device. The height-adjustable toe guard device comprises at least two stages of toe guards, a locking device and a reinforcing pull rod, wherein the toe guards are arranged on a sill and can be glidingly retracted and folded; the locking device is used for maintaining the toe guards at the folding state; the reinforcing pull rod is used for maintaining the toe guards at the unfolding state; one end of the reinforcing pull rod is connected with the toe guard at the lowest end along the gravity direction, and the other end of the reinforcingpull rod is connected with a platform or the sill. The height-adjustable toe guard device is suitable for shallow bottom pits, can meet the requirements of national standards, and can furthest decrease the running and overhauling risk of an elevator under the working condition of the shallow bottom pit, so that the safety of the elevator is same as the safety of the elevator under the normal wellshaft.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a height-adjustable toe guard device. Background technique [0002] "GB7588-2003 Elevator Manufacture and Installation Safety Code" requires that toe guards must be installed on the sill of each car, and its width should be equal to the entire clear width of the entrance of the corresponding landing. Below the vertical part of the toe guard, an inclined plane shall extend downwards, the angle between the inclined plane and the horizontal plane shall be greater than 60°, and the projection depth on the horizontal plane of the inclined plane shall not be less than 20mm. The height of the vertical part of the toe guard shall not be less than 0.75m. [0003] The function of installing toe guards is to avoid the possibility of personal injury when the car suddenly moves upwards at the leveling position, and there is a danger between the car and the landing door sill that the passen...
