Embodiment 1

[0022] Example 1, such as Figure 1-2 As shown, a foot guard includes a rectangular guard plate 1, a rectangular groove 2 is provided in the middle of the guard plate 1, and reinforcement bars 4 are fixedly connected to the four sides of the groove 2, and the thickness of the reinforcement bar 4 is greater than that of the guard plate 1. thickness, but not exceeding 0.1m, the reinforcing bar 4 is welded with a plurality of connecting rods 3 arranged in parallel. The connecting rod 3 can be cylindrical or square. Anti-slip protrusions 31 are provided on the connecting rod 3 for anti-slip, which can improve the safety of maintenance personnel. Both sides of the groove 2 define elongated through holes 21 . For some extra-large elevators, because the groove 2 in the middle is too wide, it cannot effectively play the original protection and isolation effect of the toe guard, so strip-shaped through holes 21 are also provided on both sides of the groove 2 for convenience. Serves ...

Abstract

A landing door foot protection plate belongs to elevator mechanical parts and comprises a protection plate body. A groove is arranged on the protection plate body, and at least two connection rods arranged in parallel are connected in the groove. Due to the fact that the groove is arranged on the protection plate body and the connection rods are connected in the groove, a ladder is formed, and maintainers can come out from a lift car conveniently and can reach a crawling ladder of a shaft. The landing door foot protection plate is simple in structure and convenient to use, has the effective effects of protection and isolation, and can serve as the ladder. The maintainers can move from the lift car to the shaft conveniently, and safety is improved.

Description

technical field [0001] The invention and the elevator mechanical parts are especially used for the toe guard of the hall door of the car. Background technique [0002] Hall door toe guards are installed at the bottom of the car sill, and are generally fixed installations. The function of the toe guard is that when the elevator car does not correspond to the position of the landing door, there is a gap between the car floor and the landing door ground to prevent passengers from falling into the hoistway from the gap. [0003] There are many kinds of hall door toe guards on the market, such as a rotatable car toe guard with the publication number CN102701057A, which discloses a hinged upper and lower toe guards, which are arranged on the toe guards There is a gear lever mechanism that rotates with the downward movement of the elevator, and a cam that is coaxially connected with the gear lever mechanism is arranged on the top of the toe guard, and a connecting rod mechanism th...
