[0019] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0020] The following is a further description of the embodiments of the present invention with reference to the accompanying drawings:

[0021] Reference Figure 1As shown in the figure, the fire elevator is a type of elevator, which has a self-rescue structure in case of emergency, and can greatly improve the safety of the elevator. Most of the existing elevator car top structures are closed structures. When people are trapped in the elevator in case of emergency, the trapped people in the elevator cannot achieve self-rescue, and the method of opening the car door is too dangerous. To solve this kind of problem, a car top structure for a fire elevator is proposed, which includes an elevator car 1 and a receiving chamber 11 opened in the elevator car 1. A partition board 12 for separating the receiving chamber 11 is provided at the top of the receiving chamber 11. An emergency component 2 is arranged in the partition board 12. The emergency component 2 includes an emergency escalator 21 hinged at one end of the partition board 12 on the inner side of the elevator car 1. A number of ladder frames 22 for people to climb are distributed at intervals on the top surface of the emergency escalator 21. A limiting component for limiting the rotation of the emergency escalator 21 after rotation is arranged on the bottom surface of the emergency escalator 21. A fixing component 3 for fixing the emergency escalator 21 is arranged between the emergency escalator 21 and the partition board 12; through the settings of the elevator car 1 and the receiving chamber 11, a complete elevator car 1 structure can be formed, and through the settings of the partition board 12 and the emergency component 2, the method of getting out of trouble from the elevator car top can be achieved by opening the emergency escalator 21 in the partition board 12 in case of emergency, which can greatly improve the efficiency of cooperating with rescue personnel, and through the setting of the limiting component, the stability of the emergency escalator 21 after unfolding in case of emergency can be ensured, and through the setting of the fixing component 3, the purpose of better accommodating the emergency escalator 21 in the normal state can be achieved.

[0022] It should be noted that when the elevator is in normal operation, the emergency escalator 21 is in the partition board 12 at this time, and its setting state will not affect the space size of the receiving chamber 11. When the elevator malfunctions, the operator in the elevator opens the fixing component 3 at this time, so as to achieve the purpose of unfolding the emergency escalator 21 from the partition board 12. At this time, the emergency escalator 21 rotates along the hinge point until the emergency escalator 21 rotates from the horizontal setting state to the vertical setting direction. At this time, the emergency escalator 21 can be used for the trapped people in the elevator to climb up, and cooperate with the rescue of subsequent rescue personnel.

[0023] Furthermore, in order to make the emergency escalator 21 in the vertical state more stable, in this embodiment, the limiting component includes a number of limiting card slots 212 arranged at intervals in sequence on the bottom surface of the emergency escalator 21. A limiting convex block 113 for vertically limiting corresponding to a number of the limiting card slots 212 is arranged on one side wall of the receiving chamber 11 after the emergency escalator 21 rotates; through the settings of a number of limiting card slots 212 and the limiting convex block 113, the purpose of making them match each other can be achieved. At this time, the vertical direction of the emergency escalator 21 can be limited, ensuring that the climbing personnel can climb better.

[0024] It should be noted that, in order to decorate the partition plate 12, the emergency escalator 21 in this embodiment has a closed tread surface. In order to facilitate climbing better, a ladder frame 22 for climbing is provided on the tread surface.

[0025] Furthermore, a pulling groove 221 for a hand to reach in for climbing is opened in several of the ladder frames 22; the provision of the pulling groove 221 can facilitate the hand of the climbing person to reach in, thus avoiding the occurrence of dangerous situations.

[0026] It should also be noted that the specific structure of the fixing member 3 is as follows: the fixing member 3 includes a stepped block 211 protruding outward from one side surface of the emergency escalator 21 away from the hinged end. The stepped block 211 is clamped into the partition plate 12, and the two are fixedly connected by bolts. The provision of the stepped block 211 can prevent the emergency escalator 21 from turning upwards, and the use of bolts for fixation makes the accommodation state of the emergency escalator 21 more stable.

[0027] Further, an elevator door 111 for entering and exiting the accommodation chamber 11 is opened on one side surface of the accommodation chamber 11 away from the limit convex block 113; the provision of the elevator door 111 makes the entire elevator structure more complete, and it is also a part of the normal structure, so it will not be elaborated here.

[0028] It is worth mentioning that when the trapped person climbs upwards through the emergency elevator, in order to facilitate the trapped person to escape more conveniently, in this embodiment, a escape space 112 for personnel to escape is formed between the top of the partition plate 12 and the elevator car 1, and a car top door 13 for opening or closing the escape space 112 is provided at the top of the escape space 112; the car top door 13 is connected by a detachable connection setting, which is convenient for opening the car top door 13.

[0029] Further, in this embodiment, both the car top door 13 and the emergency escalator 21 have a certain range of rotation angles, so as to avoid the occurrence of unexpected situations.

[0030] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manners. Any other implementation manners obtained by those skilled in the art according to the technical solutions of the present invention also fall within the protection scope of the present invention.
