Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by a person skilled in the art without any inventive work based on the embodiments of the present invention belong to the protection scope of the present invention.

Examples

Referring to fig. 1 to 6, the utility model discloses a passenger elevator with a safety air cushion, which comprises a vertical column 1, a car bottom 2, an upper beam 3 and a car top 4.

The car bottom 2 and the upper beam 3 are respectively and fixedly arranged at the bottom and the top of the upright post 1. The car roof 4 is fixed on the upright 1 and is positioned below the upper beam 3. The upper beam 3 is provided with an opening and closing drive source 45. A pull rope 46 is provided at the free end of the opening and closing drive source 45. The opening and closing driving source 45 is connected with a signal connection control line 450. The control wire 450 extends into the car handwheel. The bottom of the car roof 4 is hinged with a suspended ceiling 42 which can be opened to the periphery. The ends of the pull cords 46 are fixedly disposed on the free side of the ceiling 42. An air cushion 47 is supported on the ceiling 42. The air cushion 47 has an area smaller than that of the platform 2. When the elevator fails, the suspended ceiling 42 is controlled by a manual control panel to be expanded to the periphery, and the air cushion 47 supported by the suspended ceiling 42 falls onto the car bottom 2 for people in the car to use; because the air cushion 47 is positioned at the top of the car, the air cushion can directly exist in proper area and thickness without considering the occupied space, thereby providing time for ensuring safety; meanwhile, the maintenance and replacement cost is low, the device can be repeatedly used, the release threshold value can be reduced, and the personnel safety can be guaranteed as far as possible.

Specifically, four side plates 40 are fixedly provided on the surface of the car roof 4. A gap is left between the side plate 40 and the car to allow a person to pass through. The bottom end of each side panel 40 is provided with a set of hinges 41. Each group of hinges 41 is connected with a suspended ceiling 42. The four suspended ceilings 42 can stabilize the position of the air cushion 47, and prevent the air cushion 47 from shifting and falling onto the head of a person.

As a further improvement of the present invention, the suspended ceiling 42 includes a first suspended ceiling 421, a second suspended ceiling 422, a third suspended ceiling 423 and a fourth suspended ceiling 424. A first ceiling 421 and a second ceiling 422 are provided on one set of two opposing side panels 40. A drop ceiling three 423 and a drop ceiling four 424 are provided on the other set of opposing side panels 40. Ceiling three 423 and ceiling four 424 are supported between ceiling one 421 and ceiling two 422. The pulling rope 46 is fixedly arranged on the first suspended ceiling 421 and the second suspended ceiling 422. The system can reduce the complexity of the opening and closing system, ensures the stability of operation, and meanwhile, is high in releasing and collecting speed and saves time.

As a further improvement of the present invention, the guide wheels 44 are disposed at four sides of the top of the car roof 4. The traction rope 46 is wound around the guide pulley 44. The guide pulley 44 can make the steering and sliding of the traction rope 46 smoother, improving its service life.

The opening/closing drive source 45 is a small electric hoist.

The ceiling 42 is provided with a lamp hole 420 for installing an illumination lamp. Ensuring that it enables illumination within the car.

An air outlet 48 is formed in the car top 4. The air outlet 48 is located outside the side panel 40. The outlet 48 can provide the necessary gas exchange within the car.

The car roof 4 is provided with a safety window 49. The safety window 49 can provide an upward passage for people to quickly evacuate the people inside.

The platform 2 is provided with a sign area 20, a standing area 21 and a door area 22.

The marker region 20 is located directly below the air pad 47 and corresponds to the area of the air pad 47. The sign zone 20 can alert the occupants of the interior of the facility where the air cushion 47 is dropped.

The standing area 21 surrounds the outer periphery of the marking area 20. The width of the standing area 21 is larger than the length of the person from the chest to the back. The standing area 21 can remind the person of the position to stand.

The door section 22 is located on one side of the platform 2. The sign zone 20 is immediately adjacent the gate zone 22. When the elevator car drops, the position of the car door is relatively fragile in structure and belongs to the most dangerous position in the elevator car, and the car door can remind people to avoid the position.

The working principle is as follows:

the suspended ceiling 42 can be deployed downward or retracted under the control of the opening and closing drive source 45. After deployment downward, the cushion 47 drops into the sign zone 20 for protection or inspection and maintenance. When the suspended ceiling is returned, the air cushion 47 can be placed between the side plates 40, and the suspended ceiling 42 can be supported below the air cushion 47 after being returned.

When any fault occurs in the elevator, a person only needs to lean against the inner wall of the elevator car as soon as possible, and controls the opening and closing driving source 45 through the control panel to unfold the suspended ceiling 42, so that the air cushion 47 falls into the mark area 20; people around can quickly lie on the air cushion 47 and step on the wall of the car or step on the air cushion, lean on the handrail in the car to squat half or pull the handrail together to avoid danger. The whole action ring is buckled, so that the danger avoidance of the personnel can be realized only in a few seconds in one go; and the device can be repeatedly used, the threshold of application is reduced, and the safety of personnel is guaranteed as far as possible.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
