Description

Technical Field

[0001] The utility model relates to the technical field of escape passages, in particular to an externally mounted escape passage in an elevator of an old building. Background Art

[0002] An elevator is a building that serves several specific floors. The size and structure of the elevator car are convenient for passengers to enter and exit or load and unload goods. Elevators are generally planned during the construction process of the building, and some space is allocated for the installation of elevators. However, most old buildings are not equipped with elevators due to their long construction years, which is very inconvenient for carrying heavy objects or for the elderly to climb stairs. Therefore, most old buildings now have elevators installed to facilitate the up and down movement of people. Currently, most elevator cars are equipped with escape hatches. In case of danger, people can escape when the car door cannot be opened. In order to increase people's chances of escape, multiple emergency escape doors will be opened in these later added elevator shafts, and people can escape through fixed stairs. However, these escape stairs are fixed and take up a lot of space when not in use. Since the space in front of the buildings in old residential areas is already small, the space for the elevators that were added later is even smaller. Utility Model Content

[0003] The main purpose of the utility model is to provide an external escape passage in an elevator of an old building, which can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an external escape passage in an old building elevator, comprising a rear-added elevator shaft and a building, the right side of the rear-added elevator shaft is arranged on the left side of the building, the rear-added elevator shaft and the opposite side of the building are connected through a plurality of corridors, a plurality of emergency escape doors are arranged on the front side of the rear-added elevator shaft, an escape mechanism is arranged on the front side of the rear-added elevator shaft, and a plurality of the emergency escape doors are connected to the escape mechanism;

[0005] The escape mechanism includes multiple columns, a winch and multiple escape ladder assemblies. The rear sides of the multiple escape ladder assemblies are installed on the front side of the rear elevator shaft. The winch is installed on the upper part of the rear elevator shaft. The winch is connected to the upper part of the upper escape ladder assembly through a wire rope. The outer periphery of the multiple columns is connected to the front sides of the multiple escape ladder assemblies. The emergency escape doors correspond to the escape ladder assemblies one by one.

[0012] 1. When the elevator stops running due to an accident and the elevator door cannot be opened, the winch is first driven to extend the wire rope on the winch, and the folded escape mechanism begins to open. First, the column falls downward. Since multiple guardrails are connected to the column, the column falls downward and drives the guardrail to move outward, thereby rotating the pedal and side panel assembly until the pedal is horizontal. The escape ladder assembly is fully unfolded to form a staircase for escape, and while the guardrail moves outward, the telescopic sleeve is synchronously deflected and finally lies across the end of the guardrail to form a guardrail to prevent people from falling when escaping. After the emergency escape door is opened, it will be blocked by the guardrail, making it impossible for the emergency escape door to be fully opened, forming a protective plate to block the upper end of the escape ladder assembly to prevent people from falling. In addition, the escape mechanism can be folded up when not in use, which greatly reduces the floor space and does not occupy the elevator space. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-3 As shown, an external escape passage in an elevator in an old building includes a rear-added elevator shaft 3 and a building 1. The right side of the rear-added elevator shaft 3 is arranged on the left side of the building 1. The rear-added elevator shaft 3 and the building 1 are connected to each other on the opposite side through a plurality of corridors 5. A plurality of emergency escape doors 2 are arranged on the front side of the rear-added elevator shaft 3. An escape mechanism 4 is arranged on the front side of the rear-added elevator shaft 3, and a plurality of emergency escape doors 2 are connected to the escape mechanism 4.

[0019] The escape mechanism 4 includes a plurality of columns 401, a winch 402 and a plurality of escape ladder assemblies 403. The rear sides of the plurality of escape ladder assemblies 403 are installed on the front side of the rear elevator shaft 3. The winch 402 is installed on the upper part of the rear elevator shaft 3. The winch 402 is connected to the upper part of the upper escape ladder assembly 403 through a steel wire rope. The outer periphery of the plurality of columns 401 is connected to the front sides of the plurality of escape ladder assemblies 403. The emergency escape door 2 corresponds to the escape ladder assembly 403 one by one. In summary, firstly, when the elevator stops running unexpectedly and the elevator door cannot be opened, the winch 402 is first driven to extend the steel wire rope on the winch 402, and the folded escape mechanism 4 begins to open. Firstly, the column 401 falls downward. Since a plurality of guardrails 4033 are connected to the column 401, the column 4 01 falls downward, while driving the guardrail 4033 to move outward, thereby causing the pedal 4031 and the side panel assembly 4032 to rotate until the pedal 4031 is in a horizontal state, and the escape ladder assembly 403 is fully unfolded to form a staircase for escape, and while the guardrail 4033 moves outward, the telescopic sleeve 4034 is synchronously deflected, and finally lies across the end of the guardrail 4033 to form a guardrail to prevent people from falling when escaping, and the emergency escape door 2 will be blocked by the guardrail 4033 after opening, so that the emergency escape door 2 cannot be fully opened, forming a protective plate to block the upper end of the escape ladder assembly 403 to prevent people from falling, and the escape mechanism 4 can be folded up when not in use, which greatly reduces the floor space and does not occupy the elevator space.

[0020] The escape ladder assembly 403 includes multiple pedals 4031 from left to right, two front and rear side panel assemblies 4032 and a guardrail 4033. One side of the side panel assembly 4032 is rotatably connected to the left and right sides of the multiple pedals 4031. The rear side of the rear side panel assembly 4032 is fixedly connected to the front side of the rear elevator shaft 3. The lower part of the guardrail 4033 is fixedly connected to the upper part of the front side panel assembly 4032. The front side of the guardrail 4033 is fixed to the multiple columns 401. The column 401 falls downward. Since the multiple guardrails 4033 are connected to the column 401, the column 401 falls downward and drives the guardrail 4033 to move outward at the same time, thereby causing the pedal 4031 and the side panel assembly 4032 to rotate until the pedal 4031 is in a horizontal state. The escape ladder assembly 403 is fully unfolded to form a staircase for escape.

[0021] The length of the pedal 4031 is smaller than the width of the emergency escape door 2. After the emergency escape door 2 is opened, it will be blocked by the guardrail 4033, so that the emergency escape door 2 cannot be fully opened, forming a guard plate to block the upper end of the escape ladder assembly 403 to prevent people from falling.

[0022] The right side of the guardrail 4033 is rotatably connected to one side of the rear elevator shaft 3, and the other side of the telescopic sleeve 4034 is rotatably connected to the outside of the vertical pole 4035. The lower end of the vertical pole 4035 is fixedly connected to the upper part of the corridor 5. The multiple telescopic sleeves 4034 are parallel to each other. When the guardrail 4033 moves outward, the telescopic sleeves 4034 are synchronously deflected and finally span across the end of the guardrail 4033 to form a guardrail to prevent people from falling when escaping.

[0023] The width of the leftmost pedal 4031 and the rightmost pedal 4031 is greater than 50CM, which is convenient for people to stand and escape.

[0024] A no-parking sign is provided at the front side of the lower part of the rear elevator shaft 3 to prevent debris from being piled up under the escape mechanism 4, which may cause the escape ladder assembly 403 to be unable to be deployed.

[0025] Working principle:

[0026] When the elevator stops running unexpectedly and the elevator door cannot be opened, the winch 402 is first driven to extend the wire rope on the winch 402, and the folded escape mechanism 4 begins to open. First, the column 401 falls downward. Since multiple guardrails 4033 are connected to the column 401, the column 401 falls downward and drives the guardrails 4033 to move outward, thereby causing the pedal 4031 and the side panel assembly 4032 to rotate until the pedal 4031 is horizontal and the escape ladder assembly 403 is fully unfolded to form a staircase. , people can escape, and while the guardrail 4033 moves outward, the telescopic sleeve 4034 deflects synchronously, and finally lies across the end of the guardrail 4033 to form a guardrail to prevent people from falling when escaping. After the emergency escape door 2 is opened, it will be blocked by the guardrail 4033, making it impossible for the emergency escape door 2 to be fully opened, forming a protective plate to block the upper end of the escape ladder assembly 403 to prevent people from falling, and the escape mechanism 4 can be folded up when not in use, which greatly reduces the floor space and does not occupy the elevator space.
