Description

Technical Field

[0001] This invention relates to the field of elevator rescue technology, and in particular to an elevator emergency rescue device. Background Technology

[0002] With the development of elevator technology, related installation and remote management technologies have matured, leading to a decrease in operating costs. As a result, more and more buildings are installing vertical elevators to facilitate passenger access. Simultaneously, elevator car safety protection technologies have also advanced. These technologies can effectively limit further movement of the elevator car and maintain its stability in the event of a loss of control, preventing injuries to passengers and facilitating subsequent rescue efforts. However, current emergency rescue devices on the market often only allow for rapid evacuation of passengers inside the car and cannot effectively limit the car's position within the elevator shaft. This can lead to a shift in the center of gravity during passenger movement, causing the car to continue sliding downwards, posing a safety hazard and failing to meet current usage requirements. Summary of the Invention

[0003] The purpose of this invention is to provide an elevator emergency rescue device that solves the technical problems in the prior art of being unable to effectively control an out-of-control car and assist passengers inside in evacuating safely and quickly. It achieves the technical effect of stable control of the out-of-control car and facilitates the safe and rapid evacuation of passengers inside.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0005] An elevator emergency rescue device includes a car, a mounting base, and a telescopic ladder. The car has an elevator door on one side and an opening at its upper end. A top cover is rotatably connected to one side of the opening. The mounting base is located at the upper end of the car and is perpendicular to the car's entry and exit direction. Two sets of mounting bases are arranged parallel to each other. Each mounting base has movable sleeves at both ends. Supports are fixedly fitted onto the outer sides of the movable sleeves and are bolted to the car. A sliding sleeve is fitted inside the movable sleeve, and an anti-slip claw is fixed to one end of the sliding sleeve extending beyond the support. A lead screw is rotatably connected inside the mounting base, and the sliding sleeve has internal threads for moving in conjunction with the lead screw. A motor is located at the lower end of the mounting base. One end of the motor's shaft has a transmission box fixedly connected to the mounting base. The transmission box contains a gear set that drives the lead screw and motor to move the sliding sleeve. The telescopic ladder is located on one side of the top cover and is rotatably connected to the car via a rotating base for personnel transfer.

[0006] As an improvement, a light is fixed to the upper end of the mounting base, and the light is set towards the upper cover and the telescopic ladder to illuminate the upper part of the car in the elevator shaft. The lower end of the mounting base is equipped with an electrical box, and an antenna is fixed to one side of the electrical box. The electrical box contains a signal transceiver device near the antenna for remotely transmitting operating data information. The electrical box also contains a height change sensor to monitor the height change of the car in real time.

[0007] As an improvement, the top cover is provided with a guide seat on the side near the elevator door, and a winding frame is fixed on one side of the mounting seat near the elevator door. A cable is wound around the outside of the winding frame, and the cable is connected to the end face of the top cover through the guide seat to assist in lifting the top cover.

[0008] As an improvement, the telescopic ladder is offset to one side of the elevator car's axis, the telescopic ladder is located inside the opening of the elevator door, and an anti-slip mat is provided on the side of the telescopic ladder away from the elevator door to prevent people from slipping and falling while climbing.

[0009] As an improvement, the telescopic ladder has two sets of ladders that slide together. One set of ladders has a magnetic anti-slip seat on the side away from the rotating seat. The magnetic anti-slip seat is in the shape of a right-angled plate and is used to limit the connection with the sill at the elevator door.

[0010] As an improvement, the interior of the car is equipped with a ladder located directly below the top cover. The interior of the car is provided with a groove near the ladder, and a connecting rod is rotatably connected to the inner wall of the groove.

[0019] To make the content of this invention easier to understand, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0020] like Figures 1 to 5As shown, an elevator emergency rescue device includes a car 1, a mounting base 4, and a telescopic ladder 14. The car 1 has an elevator door 2 on one side and an opening at its upper end. A top cover 15 is rotatably connected to one side of the opening. The mounting base 4 is located at the upper end of the car 1 and is perpendicular to the car 1's entry and exit direction. There are two sets of mounting bases 4 arranged parallel to each other. Each mounting base 4 has movable sleeves at both ends. Supports 3 are fixedly fitted onto the outer side of each movable sleeve and are bolted to the car 1. A sliding sleeve 7 is fitted inside each movable sleeve. The sliding sleeve 7 extends from one end of the support 3 and is fixed with an anti-slip claw 6. A lead screw 18 is rotatably connected inside the mounting base 4. The sliding sleeve 7 has internal threads for moving in conjunction with the lead screw 18. A motor 8 is located at the lower end of the mounting base 4. One end of the motor 8's shaft has a transmission box 11 fixedly connected to the mounting base 4. The transmission box 11 contains a gear set that drives the lead screw 18 and the motor 8, thus driving the sliding sleeve 7 to move. The telescopic ladder 14 is located on one side of the upper cover 15 and is rotatably connected to the car 1 via a rotating seat 13 for personnel transfer. One end of the anti-slip claw 6 is made of rubber with anti-slip texture, allowing it to fully engage with the elevator shaft wall after the sliding sleeve 7 is extended, restricting further movement of the car 1.

[0021] A lighting lamp 5 is fixed to the upper end of the mounting base 4, facing the upper cover 15 and the telescopic ladder 14, for illuminating the upper part of the car 1 inside the elevator shaft. An electrical box 9 is attached to the lower end of the mounting base 4. An antenna 10 is fixed to one side of the electrical box 9. A signal transceiver is located inside the electrical box 9 near the antenna 10 for remotely transmitting operational data. A height change sensor is also located inside the electrical box 9 to monitor the height changes of the car 1 in real time. The electrical box 9 also contains a battery and a control module for controlling the operation of the motor 8 in emergency situations. A guide seat 16 is located on the side of the upper cover 15 near the elevator door 2. A winding frame 17 is fixed to one side of the mounting base 4 near the elevator door 2. A cable is wound around the outside of the winding frame 17, and the cable is connected to the end face of the upper cover 15 through the guide seat 16 to assist in lifting the upper cover 15. The electrical box 9 also includes an alarm device, which detects the current status of the car 1, the unfolding status of the ladder 20, and the activation status of the telescopic ladder 14, and broadcasts the required operating instructions according to the corresponding status to assist personnel in evacuation.

[0022] The telescopic ladder 14 is offset to one side of the axis of the elevator car 1. It is located inside the opening of the elevator door 2. An anti-slip mat 12 is provided on the side of the ladder away from the elevator door 2 to prevent people from slipping and falling while climbing. The telescopic ladder 14 has two sets of ladders that slide together. One set of ladders has a magnetic anti-slip seat on the side away from the rotating seat 13. This magnetic anti-slip seat is shaped like a right-angled plate and is used to limit the connection with the elevator door sill. The side edges of the telescopic ladder 14 are edged with rubber and have anti-slip textures for easy gripping and climbing.

[0023] The car 1 is equipped with a ladder 20 located directly below the top cover 15. A recess 19 is located inside the car 1 near the ladder 20. A connecting rod 21 is rotatably connected to the inner wall of the recess 19. The connecting rod 21 is movably connected to the ladder 20 via a movable pin. The ladder 20 can be retracted into the recess 19 to assist personnel in climbing. A knob 22 is located at the lower end of the recess 19. The upper end of the knob 22 has a limit block. A return spring is located at the connection between the knob 22 and the car 1 to ensure the limit block is locked, thus limiting the movement of the ladder 20 within the recess 19. The connecting rod 21 has a sliding groove inside, allowing the ladder 20 to be pushed in and adjusted before being inserted into the recess 19. One end of the connecting rod 21 has a right-angle notch, which restricts the movement of the ladder 20 within the connecting rod 21.

[0024] When in use, after the basic supporting facilities of the car 1 detect an abnormal state, the corresponding braking device will be activated first. Then, the sensor in the electrical box 9 will simultaneously detect the current abnormal state and start the motor 8. The sliding sleeve 7, together with the lead screw 18, will rotate to push out the anti-slip claw 6. After the anti-slip claw 6 moves a certain distance, it will contact the elevator shaft wall, thereby achieving overall braking and stability. At this time, the trapped personnel can turn the knob 22 to take the ladder 20 out of the groove 19. After the sensor detects that the position of the ladder 20 has changed, the winding frame 17 will wind up the cable and, together with the guide seat 16, lift the top cover 15. At this time, the trapped personnel can climb to the top of the car 1 and then lift the telescopic ladder 14 to lock it at the sill of the next floor, thus achieving evacuation.

[0025] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
