Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an elevator emergency rescue device. Background Art

[0002] With the continued rapid development of the economy, the urban population is increasing year by year, and the floors of urban buildings are getting taller and taller. As the only means of transporting people living or working in buildings, elevators are closely related to the safety of people living in cities. However, in the event of fires or other natural disasters, cases of people trapped in elevators dying due to delayed rescue efforts or the complex situation at the scene, which prevents rescue operations from being carried out, are common. A search revealed that Chinese Patent Publication No. CN109132764A discloses an elevator emergency rescue device, which includes an elevator shaft, a car mounted within the shaft, several ropes fixedly connected to the upper end surface of the car, a ladder fixedly mounted on the left side wall of the elevator shaft, several escape doors disposed on the left side wall of the elevator shaft, a rescue box mounted on the upper surface of the top wall of the car, an escape hatch disposed on the top wall of the car, a lift plate mounted in the escape hatch, a rope ladder mounted on the upper surface of the lift plate, and a handle disposed on the right side wall of the car. The invention relates to an elevator emergency rescue device which provides trapped people with a chance to save themselves in an emergency.

[0003] However, in actual use, this solution uses a rope ladder to reach the top of the car. Since the rope ladder is relatively soft, it will shake randomly during the climbing process. If it is not operated properly, it will cause trapped people to fall and get injured. Secondly, by installing an escape ladder on the inner wall of the elevator shaft, such a structure is relatively large in installation and use, which is not conducive to use in high-rise buildings. Utility Model Content

[0004] In order to solve the problems that the existing rescue devices are not safe to use and have high structural costs, the utility model provides an elevator emergency rescue device.

[0005] In view of the above problems, the technical solution proposed by the present invention is:

[0006] An elevator emergency rescue device includes a car, a rescue opening is opened on the top of the car, a cover plate is hinged inside the rescue opening, the car is provided with escape ladders on the inner and outer sides near the cover plate, the two escape ladders respectively include a fixed frame and a telescopic ladder, the top and the inner top surface of the car are respectively installed with fixed frames, the inner walls of the fixed frames are respectively connected with shafts, the fixed frames are hinged to each other with one end of the telescopic ladder through the shaft, and the hinge directions of the two telescopic ladders are perpendicular to each other.

[0007] Furthermore, the cover plate includes a plate, a bottom edge of the plate is provided with a bayonet, and an inner wall of the bayonet is embedded with a magnetic block.

[0008] The beneficial effect of adopting the above further solution is that, through the provision of the bayonet, one side of the plate can be restricted inside the rescue opening to avoid collapsing downwards.

[0009] Furthermore, one side of the magnetic block is adsorbed and connected to the inner wall of the rescue port.

[0010] The beneficial effect of adopting the above further solution is that the plate can be kept stable inside the rescue opening through the adsorption connection of the magnetic block.

[0011] Furthermore, a plurality of rope buckles are installed on the inner wall of the car, and a pull rope is connected to the inside of the plurality of rope buckles, and one end of the pull rope is connected to one end of the telescopic ladder located inside the car.

[0012] The beneficial effect of adopting the above further scheme is that by connecting and using the pull rope, it is convenient to extend the pulling end of the telescopic ladder to a lower position, thereby facilitating the unfolding of the telescopic ladder inside the car. Combined with the connection and use of the rope buckle, it is convenient to limit the pull rope to a specified position, so that the pull rope can be pulled at any time.

[0013] Furthermore, a cross bar is welded inside the fixing frame, and the cross bar is parallel to the telescopic ladder.

[0014] The beneficial effect of adopting the above further solution is that, by welding the crossbars, the structural strength of the fixing frame is enhanced while also helping to improve the stability of the telescopic ladder.

[0015] Furthermore, a car door is slidably connected to one side of the outer wall of the car, and the hinged position of the telescopic ladder on the top of the car is toward one side of the car door.

[0016] The beneficial effect of adopting the above further solution is that, by setting the orientation of the telescopic ladder, the telescopic ladder on the top of the car can be connected to the hall door position in the elevator shaft.

[0017] Furthermore, the outer wall of the telescopic ladder is provided with an anti-slip mat.

[0018] The beneficial effect of adopting the above further solution is that the anti-slip effect of the telescopic ladder is improved by using the anti-slip pad as a set, making it safer to use.

[0019] Furthermore, the material of the rope buckle is set to be elastic rubber.

[0020] The beneficial effect of adopting the above further solution is that, by utilizing the easily deformable property of elastic rubber, the draw cord can be easily taken in and out of the cord buckle.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] The elevator emergency rescue device, through the coordinated use of the rescue opening, the cover plate and the escape ladder, makes the rescue device more stable and safe during use, and effectively saves construction costs. Specifically, by pulling one end of the pull rope, it drives one end of the telescopic ladder to swing inside the fixed frame, and continues to apply tension to extend the telescopic ladder until it touches the inner bottom surface of the car, thereby ensuring the stability of the telescopic ladder when in use. Then, by lifting the cover plate, the cover plate is flipped upward, causing the rescue opening to be open, thereby facilitating the trapped person to climb out of the rescue opening along the telescopic ladder. Then, by bending the telescopic ladder on the top of the car, the telescopic ladder is extended upward until one end of the telescopic ladder touches the hall door position in the elevator shaft, thereby facilitating the trapped person to escape safely along the hall door. Through such a structure that is easy to store, manufacturing costs can be effectively saved. BRIEF DESCRIPTION OF THE DRAWINGS
