no. 1 Embodiment ＞

[0026] figure 2 It is a perspective schematic diagram schematically showing the inside of the car of the first embodiment of the elevator of the present invention. A handrail 202 is provided inside the car 110. The armrest 202 is connected to the car wall 112 through a bracket. The bracket of this embodiment is composed of two supporting rods 204.

[0027] image 3 Yes figure 2 A schematic view of the A-A section shown. As shown in the figure, at the other end of the support rod 204 that is not connected to the armrest 202, a positioning block 302 is provided. The positioning block 302 is made of a material that can be attracted by an electromagnet. For example, the positioning block 302 may be composed of a magnet, or may be composed of ferromagnetic materials such as iron alloy, nickel alloy, or cobalt alloy. A mounting frame 312 is provided on the outer side of the car wall 112, and the mounting frame 312 can stably support the support rod 204. Insert the end of the sup...

no. 2 Embodiment ＞

[0033] Figure 7 It is a schematic perspective view schematically showing the inside of the car of the second embodiment of the elevator of the present invention. This embodiment is a modification of the first embodiment. In this embodiment, those components that are the same, corresponding or equivalent to those of the first embodiment are given the same signs, and the description of these parts will be omitted or simplified. The biggest difference between this embodiment and the first embodiment is that the bracket connecting the armrest 202 and the car wall 112 is composed of a support rod 204 and an armrest seat 206. Since the armrest seat 206 connects the two support rods 204 into one body, the stability of the entire bracket is increased.

[0040] Picture 11 It is a perspective schematic diagram schematically showing the inside of the car of the third embodiment of the elevator of the present invention. A handrail 202 is provided inside the car 110. The armrest 202 is connected to the car wall 112 through a bracket. The bracket of this embodiment is composed of a support rod 204 and an armrest seat 206.

As shown in the figure, at the other end of the armrest seat 206 where the support rod 204 and the armrest 202 are not connected, there are more than two insertion rods 922. A mounting frame 912 is provided on the outer side of the car wall 112, and the mounting frame 912 can stably support the armrest seat 206 passing through the car wall 112. Insert the end of the armrest seat 206 with the plunger 922 from the inside of the car 110 into the car wall opening 112a opened on the car wall 112, the end of the armrest base 206 and the ...

Abstract

The invention relates to an elevator. The elevator comprises a shaftway, an elevator car, a handrail, a ladder stand, a support, a positioning block and electromagnets, wherein the handrail is located in the elevator car; the ladder stand is arranged below a landing door sill of an end station on the bottom layer; the support is connected with the handrail and the car wall; the positioning block is arranged at the end, not connected with the handrail, of the support and made of a material capable of being attracted by the electromagnets; one electromagnet is arranged on the outer side of the car wall and can attract the positioning block to fix the support and the handrail to the car wall when powered on; and the other electromagnet is adjacent to a sill groove of the landing door sill of the end station at the bottom layer. A connecting body of the handrail, the support and the positioning block can be detached from the car wall by powering off the electromagnet located on the outer side of the car wall. The positioning block of the connecting body is inserted into the sill groove of the end station on the bottom layer, the electromagnet adjacent to the sill groove is powered on, the positioning block is attracted by the electromagnet adjacent to the sill groove to fix the connecting body to the landing door sill, and then the handrail can be used as an auxiliary handle for people to climb downwards or upwards a pit through the ladder stand.

Description

Technical field [0001] The invention relates to an elevator, in particular to a handrail in an elevator car and a ladder in a pit. Background technique [0002] The bottom part of the elevator hoistway below the bottom end station is the pit. The pit is equipped with buffers and other devices, and there is also a climbing ladder for maintenance personnel to go down to the pit. The climbing ladder is often set under the sill of the landing door at the bottom end station. Since the climbing ladder is under the landing door sill, it is difficult for people to see the climbing ladder directly after opening the landing door. Therefore, if the maintenance personnel want to get down to the pit from the bottom end, they need to stretch one foot down the pit, look for the climbing ladder under the sill of the landing, and then use the climbing ladder to go down the pit. In the absence of handrails, the maintenance staff had no choice but to hold the opened landing door or the sill groo...
