Abstract

The invention discloses an elevator car provided with an overhaul channel. The elevator car comprises a car bottom. The overhaul channel which is vertically through is formed in the car bottom. An overhaul door which can be opened towards the interior of the elevator car and close the overhaul channel when closed is arranged above the overhaul channel. A crawling ladder is further arranged on the edge of an opening in the lower portion of the overhaul channel. According to the elevator car, the overhaul channel is added in the car bottom; when an elevator operates normally, the overhaul door above the overhaul channel is closed; when the elevator needs to be overhauled, an overhaul worker enters the elevator car, then opens the overhaul door of the car bottom and enters a pit directly through the crawling ladder quite conveniently and safely.

Description

A kind of car with access path

Technical field

The present invention relates to the car of cage lifter, especially a kind of car with access path.

Background technology

When pit 100 pairs of elevators that current service personnel enters elevator overhaul, be generally by mobile car 1, make to form a space between the ground of car 1 and layer door 2, then people is for opening layer door 2, enters pit 100.The pit 100 that this mode enters elevator place building is not only very inconvenient, elevator emergency guard's valve not easy to operate, and is absolutely unsafe, and people's tegillum door 2 easily occurs and clamps, or people is sandwiched in the dangerous situation in the space between the ground of layer door 2 and car.

Summary of the invention

In view of this, the object of the invention is the defect in order to overcome prior art, providing a kind of easy access personnel to enter elevator pit and the car of the safer band access path of turnover.

For achieving the above object, the invention provides a kind of car with access path, comprise at the bottom of sedan-chair, it is characterized in that: the access path offering up/down perforation at the bottom of described sedan-chair, the top of described access path is provided with the access door can closing described access path when can open in car and close; The lower opening edge of described access path is also provided with cat ladder.

Preferably, described cat ladder has stowed position and expanded position, and when stowed position, described cat ladder covers in the lower opening of described access path, when expanded position the lower end of described cat ladder extend obliquely be supported on elevator place building pit on.

Wherein, in one embodiment, described cat ladder is scalable cat ladder.

Compared to prior art, the present invention increases an access path at the bottom of sedan-chair, and when needing to overhaul elevator, service personnel is introduced in car, then opens the access door be positioned at the bottom of sedan-chair, directly enters pit by cat ladder, very convenient, safer.

Adopt the car of band access path of the present invention, have the following advantages:

(1) entering pit need not artificial mobile car, without people for opening layer door;

(2) can not therefore may relative motion and the danger of people occurs to press from both sides between car and hoistway as prior art, safer;

(3) mode of pit is entered by the access path at the bottom of sedan-chair, for convenient human users's emergency stop switch;

(5) after entering pit in prior art, layer door needs to stay open mode, likely produces danger to peripheral personnel; And the present invention, come in and gone out by cab interior, can be driven by gate, avoid unnecessary danger.

Fig. 1 is the schematic diagram that in prior art, service personnel enters elevator pit.

Fig. 2 is the front view of car of the present invention when elevator normal operating condition.

Fig. 3 is the birds-eye view of car of the present invention when elevator normal operating condition.

Fig. 4 is the front view of car of the present invention when overhauling elevator state.

Detailed description of the invention

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.

Refer to Fig. 2 to 4, a kind of car 10 with access path, to comprise at the bottom of sedan-chair 11, the access path 12 of up/down perforation is offered in 11 at the bottom of sedan-chair, the top of access path 12 is provided with the access door 13 can closing access path 12 when can open in car and close, and the lower opening edge of access path 12 is also provided with cat ladder 14.

As shown in Figures 2 and 3, when elevator normal operating condition, car 10 moves to lowest floor, and access door 13 is in closure state, and the access path 12 on 11 to be closed at the bottom of sedan-chair by access door 13, after access door 13 is closed with at the bottom of sedan-chair 11 surface concordant.Cat ladder 14 is in stowed position, and after packing up cat ladder 14, cat ladder 14 covers in the lower opening of access path 12.

As shown in Figure 4, when service personnel need to enter pit 100 overhaul time, opened by layer door, enter car from the car door of elevator, then open access door 13, access door 13 leans against on the inwall of car 10 after rotating shaft upset is opened.Then, cat ladder 14 is turn to expanded position downwards along rotating shaft by service personnel, the lower end of cat ladder 14 extend obliquely be supported on elevator place building pit 100 on.By this access path 12 and cat ladder, service personnel can pass in and out pit easily, very convenient and safety.

In the present embodiment, cat ladder 14 can adopt telescopic structure, to adapt to the pit of different depth.The rotating shaft of cat ladder 14 and the rotating shaft of access door 13 are all positioned on the edge, the same side of access path 12, and arranged in parallel.

After car due to employing band access path of the present invention, the mode of turnover pit is more safe and convenient compared to traditional mode, avoids unnecessary risk.

Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and implement according to this; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.

Claims

1. the car with access path, comprises at the bottom of sedan-chair, it is characterized in that: the access path offering up/down perforation at the bottom of described sedan-chair, and the top of described access path is provided with the access door can closing described access path when can open in car and close; The lower opening edge of described access path is also provided with cat ladder.

2. a kind of car with access path according to claim 1, it is characterized in that: described cat ladder has stowed position and expanded position, when stowed position, described cat ladder covers in the lower opening of described access path, when expanded position the lower end of described cat ladder extend obliquely be supported on elevator place building pit on.
