DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Example 1

[0033] See also Figure 1-5 The utility model provides a technical solution: an elevator top escape structure equipped with a folding telescopic ladder, comprising:

[0034] A car top plate 1, on which an escape hatch 11 is provided;

[0035] A movable plate 2 is hinged on the car roof 1. A telescopic ladder 9 is provided on the movable plate 2. The telescopic ladder 9 includes a folding ladder rod 91 and a pedal 92. The end of the movable plate 2 is locked with the car roof 1 by a rotating handle 21.

[0036] The emergency self-rescue box 4 is fixedly mounted on the side wall of the car, and a manual pull rod 41 is arranged inside the emergency self-rescue box 4:

[0037] The self-rescue box 5 is detachably mounted on the movable plate 2 .

[0038] By installing a folding telescopic ladder on the top of the elevator, sufficient space is reserved for the operator, making full use of the limited space inside the car to achieve the effect of escaping from the car smoothly. The rescue functional top has two opening methods, manual and electric, for escape. It is convenient to operate and meets the needs of self-rescue under extreme conditions when the circuit is blocked.

[0039] The telescopic ladder 9 also includes an electric push rod 93, an auxiliary rod 94 and a cover plate recovery bracket 95. The electric push rod 93 is rotatably mounted on the car roof 1, and the piston rod end of the electric push rod 93 is pivotally connected to the auxiliary rod 94. One end of the auxiliary rod 94 is rotatably mounted on the movable plate 2, and the other end is pivotally connected to the folding ladder rod 91. One end of the cover plate recovery bracket 95 is rotatably mounted on the movable plate 2, and the other end is rotatably mounted on the car roof 1.

[0040] The telescopic ladder 9 can be electrically designed, and the electric push rod 93 can be controlled by the remote control panel. The piston rod of the electric push rod 93 can be opened and retracted by telescopically controlling the movable plate 2 to be rotated, so as to facilitate opening the telescopic ladder 9, and the cover plate recovery bracket 95 can assist in closing the movable plate 2. The remote control panel can be placed in the emergency self-rescue box 4.

[0041] Two parallel baffle rings 51 are arranged on the inner wall of the self-rescue box 5, and an annular baffle matching the shape of the self-rescue box 5 is arranged on the movable plate 2, and an annular convex rib for buckling with the baffle ring 51 is arranged on the outer side of the annular baffle. A partition is also arranged inside the self-rescue box 5 to separate the space. The self-rescue box 5 is buckled on the movable plate 2, and self-rescue items such as a call device, a flashlight, and a rope are placed inside it. After the movable plate 2 is opened, the trapped person can choose whether to use them according to his own ability.

[0042] The self-rescue box 5 is a transparent plastic combination, which is convenient for timely finding the internal self-rescue items.

[0043] The manual pull rod 41 includes a coaxially arranged outer tube 411 and an inner tube 412, and a hook 413 is provided at the end of the inner tube 412. The coaxially arranged outer tube 411 and inner tube 412 realize a telescopic structure, which can be folded to reduce the length and is easy to be stored in the emergency self-rescue box 4.

[0044] The emergency self-rescue box 4 is provided with an emergency light 42. When the elevator operation fails, the emergency light 42 on the emergency self-rescue box 4 inside the car emits light, provides lighting, and is convenient to observe the situation inside the car.

[0045] Working principle: When the elevator fails, the passengers trapped in the elevator car take out the manual pull rod 41 in the emergency self-rescue box 4, and the manual pull rod 41 hooks the ring structure on the rotating handle 21 through the top hook 413, and then rotates the rotating handle 21 to unlock the movable plate 2. After that, the manual pull rod 41 can be pulled down to open the escape hole 11 blocked by the movable plate 2, and finally the telescopic ladder 9 can be pulled down to unfold, so as to effectively achieve escape.
