Embodiment 1

[0021] Such as figure 1 and 2 A telescopic toe guard is shown. The toe guard is installed at the bottom of the car and includes an upper inner plate 1 and a lower outer plate 2. The upper inner plate 1 and the lower outer plate 2 are connected by a slide rail 5. The top of the upper inner plate 1 is fixed on the bottom beam 12 of the car, and the lower outer plate 2 moves up and down along the slide rail 5; it also includes a screw 6, the bottom of which is fixed on the lower outer plate 2, and the upper part of the screw 6 is movable on the upper On the inner panel 1.

[0022] The toe guard provided in this embodiment is a telescopic structure, and slide rails 5 are respectively provided on the two side walls of the upper inner plate 1, and the lower outer plate 2 and the upper inner plate 1 are connected by the slide rail 5, and the sliding stroke of the slide rail 5 is greater than that of the toe guard The compression stroke makes it possible to automatically adjust the ...

Embodiment 2

[0026] On the basis of Example 1, the lower outer plate 2 is horizontally provided with a first fixing member 3, and the bottom of the screw rod 6 passes through the first fixing member 3 and is fixed on the first fixing member 3 by upper and lower nuts ; The upper inner plate 1 is horizontally provided with a second fixing member 4, and the upper part of the screw 6 passes through the second fixing member 4 and is movable on the second fixing member 4 through an upper nut. Since the screw rod 6 is only provided with a nut above the second fixing member 4, the screw rod 6 can freely extend upwards to play a guiding role, the structure is simple, and the operation is convenient. The first fixing part 3 and the second fixing part 4 are arranged on the bottom of the lower outer panel 2 and the upper inner panel 1 respectively, and the compression size can be adjusted within a certain range to realize complete compression of the toe guard.

[0027] In order to prevent the toe guar...

Embodiment 3

[0030] On the basis of Embodiment 1 or 2, the bottom of the lower outer panel 2 is provided with a bent bolt fixing part 11 . The bottom of the lower outer plate 2 is fixedly connected with a bending edge, which is welded to the bending bolt fixing part 11. There are two bending bolt fixing parts 11, which are respectively arranged at both ends of the bottom of the lower outer plate 2. During maintenance, the elevator stops On the bottom layer, screw on the bolts to fix the car in the bottom pit. The bolts touch the ground to compress the toe guards to prevent the bending edge from touching the ground.

Abstract

The invention relates to a toe guard for an elevator, and particularly provides a telescopic type toe guard. The telescopic type toe guard is mounted at the bottom of a cage, and comprises an upper inner plate and a lower outer plate, wherein the upper inner plate is connected with the lower outer plate through sliding rails; the top of the upper inner plate is fixed on a bottom beam of the cage; the lower outer plate moves up and down along the sliding rails; the telescopic type toe guard further comprises screws; the bottoms of the screws are fixed on the lower outer plate; and the upper parts of the screws are movably arranged on the upper inner plate. According to the telescopic type toe guard provided by the invention, the requirement on the height of a bottom pit is reduced; furthermore, the problem that maintenance personnel or a passenger falls into a shaftway due to the fact that the conventional toe guard is not long enough is solved, the safety of maintenance and loading is improved, an enough safe distance is guaranteed, and the damage to the toe guard due to collision with the bottom pit is avoided; and the toe guard is convenient to mount, and the cost is reduced.

Description

technical field [0001] The invention relates to a foot guard for an elevator, in particular to a telescopic foot guard. Background technique [0002] With the rapid development of the construction industry, houses are built higher and higher, and elevators are becoming more and more important in people's daily life. In the elevator industry, elevators need to be checked and repaired frequently. However, accidents may occur during the elevator inspection process. In order to avoid injury to personnel when accidents occur, it is necessary to install toe guards at the bottom of the car. The existing toe guard meets all the requirements of the national standard, is suitable for the standard pit depth, can completely reflect the required function, and has low manufacturing cost and simple installation process. [0003] However, for pits with relatively small depths, the existing foot guards cannot meet the requirements, mainly in the following aspects: first, sufficient safety d...
