Description

Technical Field

[0001] The utility model relates to the technical field of elevator safety, in particular to an elevator accident protection device. Background Art

[0002] With the continuous improvement of living standards, elevators have become an important means of transportation and are mainly used in residential buildings, office buildings, etc., bringing great convenience to people's lives. However, elevator accidents have occurred frequently in recent years, seriously threatening people's lives and safety. At present, many elevators are "over-aged" and have untimely quality inspection and maintenance, which makes elevators prone to falling accidents. Elevator falls will produce huge impact force that directly causes personal injury or even death to passengers.

[0003] Publication No. CN117262953B discloses an elevator accident protection device, which is equipped with several handrails. The airbag is inflated and expanded to extend outward, pushing the guide plate to rotate outward, thereby guiding and protecting the person's movements; the support part is set to be curved toward the inside of the installation chamber, so that the airbag can support it when it is inflated. However, after the elevator falls due to an accident, the airbag inside fills more space inside the car, resulting in a decrease in air circulation, and the elevator shape will be deformed to a certain extent due to the impact, resulting in the blockage of the connecting channel between the internal space of the car and the external connection, further reducing the air circulation, and then reducing the oxygen content of the air inside, which can easily cause the internal personnel to faint due to the reduced oxygen content and affect rescue. For this reason, we propose an elevator accident protection device. Utility Model Content

[0010] Specifically, one end of the multi-way connecting pipe away from the air pump is provided with an external communication pipeline for assisting air circulation.

[0011] By adopting the above technical solution, multiple air circulation channels are added to avoid the blockage of the gas channel caused by the deformation of the car, which affects the amount of air circulation.

[0012] Specifically, the fiber composite connector and the fluid-filled top cover are inserted into a plug-in groove opened at the bottom end of the car protection frame.

[0024] See also Figure 1-3 , the utility model embodiment provides a technical solution: an elevator accident protection device, comprising a car protection frame 1, air supply ports 2 are respectively installed on both sides of the interior of the car protection frame 1, and the air supply ports 2 are fixedly connected to the vent surface of the fixing frame 3, and the end of the fixing frame 3 away from the air supply port 2 is connected with an air flow channel 4, the top of the air flow channel 4 is connected to the air inlet of the pump 5, the air outlet of the pump 5 is connected to one side of the multi-way connecting pipe 6, and the top of the multi-way connecting pipe 6 is connected to the bottom end of the air filter port 7;

[0025] The bottom end of the car protection frame 1 is fixedly connected to a protection base 8, and both sides of the top of the protection base 8 are respectively fixedly connected to fiber composite connectors 9, and the top of the fiber composite connector 9 is fixedly connected to a buffer base 10, and a hydraulic buffer 11 is fixedly connected to the center of the surface of the buffer base 10, and the top of the hydraulic buffer 11 is fixedly connected to the bottom end of the fluid-filled top cover 13.

[0026] When in use, multiple gas circulation devices are used to ensure air circulation inside the car, so as to prevent the deformation of the car caused by impact from blocking the air circulation channel and reducing the gas circulation volume, thereby reducing the fainting of trapped persons caused by lack of oxygen and affecting the rescue efficiency. In the event of an impact, the buffering and strength reinforcement structures at the top and bottom can be used to improve the car's anti-fall ability, reduce the degree of deformation of the car caused by the elevator sliding to the bottom, relatively reduce the difficulty of rescue, and improve the efficiency of rescue.

[0027] As shown in the figure, the side wall of the car protection frame 1 is provided with windows for air circulation.

[0028] When in use, the ventilation window on the top is used to facilitate internal gas circulation, and can also be used as an escape route when in use.

[0029] As shown in the figure, one end of the multi-way connecting pipe 6 away from the air pump 5 is provided with an external communication pipeline for assisting air circulation.

[0030] When in use, multiple air circulation channels are added to avoid deformation of the car causing blockage of the gas channels and affecting the amount of air circulation.

[0031] As shown in the figure, the fiber composite connector 9 and the fluid-filled top cover 13 are inserted into the insertion groove 14 opened at the bottom end of the car protection frame 1.

[0032] When in use, the fiber connector is connected via the plug-in groove 14 , so that the car protection frame 1 can be connected to the protection base 8 .

[0033] As shown in the figure, two sections of the side walls of the buffer base 10 and the fluid-filled top cover 13 facing each other are respectively provided with spring connectors 12 for auxiliary connection.

[0034] In use, the spring connection 12 assists in connecting and filling the top cover 13 and the cushioning base 10 with a cushioning fluid.

[0035] The working principle and use process of the utility model are as follows: when the internal main control board detects that the car is running abnormally, the air pump 5 is first started urgently through the internally installed backup power supply, and the external gas is sucked into the air pump 5 through the air filter port 7 and the multi-way connecting pipe 6, and then the relatively filtered air in the elevator shaft is pumped into the car protection frame 1 through the air flow channel 4, the fixing frame 3 and the air supply port 2 to ensure the oxygen content of the air inside the car, and the holes opened without pipelines are used to avoid the car from being deformed to a certain extent, resulting in the ectopic deformation of the pipeline causing the gas channel to be disconnected and unable to supply fresh air, and the stale gas in the car is discharged through the top of the car protection frame 1 and the other connecting ports. When the car slides, the main impact force is borne by the fiber composite connector 9 fixed on the top of the protection base 8. The fiber composite connector 9 is buffered by the hydraulic buffer 11 and the spring connector 12 arranged between the buffer base 10 on the top and the fluid-filled top cover 13 to reduce the buffering force, thereby improving the anti-fall strength of the car protection frame 1 and preventing small slips from affecting the service life of the fiber composite connector 9. The protection base 8 contacts the ground to absorb the impact force generated when the car slides and hits the buffer device at the bottom of the elevator shaft. The car protection frame 1 is plugged and connected to the protection base 8 through the plug-in groove 14 and fixed, thereby protecting the car.
