Description

Technical Field

[0001] This utility model relates to the field of rescue tools, specifically to a rescue device for garbage pits. Background Technology

[0002] Waste-to-energy incineration has gradually become the mainstream solution for municipal solid waste treatment. However, with the development of the waste-to-energy incineration industry, some significant risks during operation have also been exposed. Due to the approximately 8-meter drop between the unloading hall platform and the bottom of the waste pit, the risks of vehicles falling from height during unloading and personnel falling from height during sanitation of the unloading hall are particularly prominent. These falls not only have the consequences of ordinary falls from height, but also pose a greater risk of injury or death due to poisoning and asphyxiation caused by the large amounts of toxic and harmful gases present in the waste pit during operation. Therefore, timely rescue is crucial after a fall accident. However, existing waste-to-energy incineration plants lack a systematic waste pit rescue system, and most accidents require requesting assistance from the fire department and using cranes for rescue. This results in long waiting times and increases the level of danger.

[0003] Chinese patent CN217102975U discloses an emergency rescue device for waste storage facilities, but it only provides a single emergency rescue lifting device and does not address scenarios with multiple obstacles. However, during the production process of waste incineration power plants, to ensure convenient waste unloading, the rescue device cannot be fixed on-site. Furthermore, because this rescue device requires a large counterweight, its movement is extremely inconvenient, failing to achieve the purpose of rapid rescue. If rapid rescue cannot be achieved, the purpose of emergency rescue cannot be fulfilled. Utility Model Content

[0026] Example

[0027] like Figure 1 As shown, this utility model discloses a garbage pit rescue device, which is detachably connected to the crossbeam of the garbage pit unloading door. The device includes: a support base 3, a straight ladder 4, a telescopic crossbeam 15, a fixed upright 16, a winch assembly, and a rescue stretcher 23. One side of the support base 3 is detachably connected to the crossbeam of the garbage pit unloading door. The other side of the support base 3 is equipped with the straight ladder 4, the telescopic crossbeam 15, and the fixed upright 16. The straight ladder 4 extends into the garbage pit to allow rescue personnel to enter and exit. The bottom of the fixed upright 16 is connected to the top of the support base 3, and the top of the fixed upright 16 is connected to one end of the telescopic crossbeam 15. The other end of the telescopic crossbeam 15 is equipped with a fixed pulley 9. The top of the support base 3 is equipped with a winch assembly, which includes a steel wire rope 8. The steel wire rope 8 passes through the fixed pulley 9 and is connected to the rescue stretcher 23. Driven by the winch assembly, the steel wire rope 8 moves the rescue stretcher 23 in and out of the garbage pit. In this embodiment, the straight ladder 4 is a telescopic stainless steel ladder, which allows rescuers to quickly enter and exit the garbage pit while saving space. The structure of the straight ladder 4 can adopt conventional settings in the field, and will not be described in detail here. The steel wire rope 8 is an anti-rotation steel wire rope (8×19S+IWRC), which has the characteristics of torsion resistance and durability, preventing the rescue stretcher 23 from rotating and impacting during the lifting process, and preventing secondary impact injuries and spinal injuries to the falling personnel.

[0028] In this embodiment, the garbage pit rescue device is installed and fixed by detachably connecting one side of the support base 3 to the crossbeam of the garbage pit unloading door, utilizing the support and limiting function provided by the crossbeam. A straight ladder 4, a telescopic crossbeam 15, and a fixed upright 16 are provided on the other side of the support base 3, and the straight ladder 4 extends into the garbage pit, thus enabling rescuers to enter and exit the garbage pit conveniently and quickly. The fixed upright 16 and the telescopic crossbeam 15 are fixed to the top of the support base 3, and a fixed pulley 9 is provided at the other end of the telescopic crossbeam 15. At the same time, a winch assembly is provided on the top of the support base 3. The wire rope 8 of the winch assembly passes through the fixed pulley 9 and is connected to the rescue stretcher 23. Driven by the winch assembly, the wire rope 8 drives the rescue stretcher 23 in and out of the garbage pit, using the rescue stretcher 23 to rescue the fallen person, avoiding secondary impact injury and spinal injury to the fallen person during the rescue process, improving rescue efficiency while ensuring the personal safety of the fallen person.

[0029] In the event of a vehicle or person falling from a height, the first priority is to rescue the fallen person from the garbage pit to prevent secondary injuries such as poisoning and suffocation caused by prolonged immersion in the pit. According to GBZ 2.1-2019 Occupational Exposure Limits for Hazardous Factors in the Workplace, a table of exposure times and safety limits for common hazardous gases in confined spaces shows that at an H2S gas concentration of 100 ppm, unprotected personnel exposed for 15-30 minutes will be in life-threatening danger. Therefore, controlling the rescue time is crucial for effective rescue.

[0030] like Figure 1 As shown, to expedite the rescue of a person falling from a garbage pit, the rescue device in this embodiment mounts all rescue tools on a support base 3, designed for a stilt-like configuration. This ensures that the supervisor can quickly transfer the entire set of rescue tools from the emergency supplies storage point to the accident unloading gate after discovering a fall. Furthermore, the support base 3 is made of stainless steel, providing high structural strength and minimizing the overall weight of the device. A left fixing bolt 1 and a right fixing bolt 2 are symmetrically located on the left and right sides of the rear end face of the support base 3. When a rescue is needed, the support base 3 spans across the crossbeam of the garbage unloading gate. The straight ladder 4, telescopic crossbeam 15, and fixed upright 16 are positioned above the garbage pit, and both the left fixing bolt 1 and the right fixing bolt 2 are connected and fixed to the crossbeam of the garbage unloading gate. This ensures that the support base 3 is fixed to the crossbeam of the garbage unloading gate, eliminating the need for counterweights and other complex accessories, making the entire rescue device lighter and more flexible. It is understandable that, in order to improve the stability of the rescue device, the length of the support base 3 can be set to match the length of the garbage unloading gate beam, so as to increase the contact area between the support base 3 and the garbage unloading gate beam.

[0031] A support beam 12 is provided at the top center of the support base 3 to improve the structural strength of the support base 3. A first diagonal support 13 is provided between the top of the support base 3 and the fixed upright 16, and a second diagonal support 14 is provided between the telescopic beam 15 and the fixed upright 16. In this embodiment, the telescopic beam 15 and the fixed upright 16 form a monohedral boom. The length of the telescopic beam 15 can be adjusted according to the position of the person falling, ensuring that rescue can be carried out directly above the falling person; a support diagonal beam is provided on each side of the fixed upright 16 to ensure the stability of the entire monohedral boom.

[0032] In this embodiment, the winch assembly also includes an electric hoist 6 and a height-adjustable support pulley 7. The electric hoist 6 and the support pulley 7 are respectively located on opposite sides of the top of the support base 3. One end of the wire rope 8 is wound around the electric hoist 6, and the other end of the wire rope 8 passes through the support pulley 7 and the fixed pulley 9 in sequence to connect with the rescue stretcher 23. The support pulley 7 provides support for the wire rope 8 to prevent it from falling. By setting the height-adjustable support pulley 7, the height of the support pulley 7 can be adjusted according to the length change of the telescopic beam 15 to ensure that the wire rope 8 can be properly wound and unwound.

[0033] Furthermore, the end of the wire rope 8 is provided with a first hook 10, and the rescue stretcher 23 is provided with a second hook 22. The first hook 10 and the second hook 22 are connected to achieve the connection between the wire rope 8 and the rescue stretcher 23.

[0034] In this embodiment, to prevent secondary impact injuries and spinal injuries to the fallen person during the rescue process, the rescue stretcher 23 is a PE plastic basket-type rescue stretcher. Once the rescuers reach the garbage pit, the fallen person is smoothly transferred onto the rescue stretcher 23, and there are no impact issues during the lifting process. Compared to the previous cage-type transfer method, the PE plastic basket-type rescue stretcher is lighter and easier to move; it also facilitates the transfer of the fallen person and prevents spinal injuries during the lifting process.

[0035] Based on a person's weight not exceeding 150kg and a PE plastic basket rescue stretcher not exceeding 50kg:

[0036] Total weight = 150 + 50 = 200 kg

[0037] For emergency rescue needs, the calculation is based on ≥200% rated load for 2 minutes:

[0038] Load = 200 × 2 = 400 kg

[0039] The electric hoist 6 is used for rapid lifting and precise positioning in rescue operations. Safety, reliability, and portability were key considerations during selection, leading to the choice of a 1T load capacity electric hoist 6. The lifting speed is controlled by a dual-speed / frequency converter, achieving a high speed of 5-10 m / min for rapid rescue. The braking system uses dual braking (electromagnetic braking + mechanical braking), automatically locking upon power failure. The protection rating is IP65 / IP67 (dustproof and waterproof). Due to the presence of methane and flammable gases in the surrounding environment, posing an explosion risk, an explosion-proof motor (Ex dⅡCT4 certified) was selected. The control method combines wireless remote control and local control, with an emergency stop button. Overload protection features include electronic weighing and mechanical limit switches, automatically stopping in case of overload.

[0040] like Figure 1 and Figure 2 As shown, a fan 20 is also provided on the top of the support base 3, and a foldable air duct 21 is provided at the output end of the fan 20. During rescue operations, the air duct 21 is placed near the person who fell into the garbage pit. Furthermore, the fan 20 can specifically be an axial flow fan. Most deaths from garbage pit falls are due to excessive inhalation of toxic and harmful gases inside the garbage pit. To ensure that the person does not suffer poisoning and suffocation before being rescued from the garbage pit, rescuers immediately start the axial flow fan after transferring the rescue equipment to the accident unloading door and throw the air duct 21 near the person who fell, continuously ventilating the area around the person to reduce the concentration of toxic and harmful gases and ensure that the person is protected from secondary harm by toxic and harmful gases.

[0041] like Figure 1 As shown, the top of the support base 3 is provided with a first bracket 17 and a second bracket 18. The fan 20 is connected to the first bracket 17 and the second bracket 18, which makes the installation simple, stable and reliable.

[0042] In this embodiment, a mobile power supply 5 is also provided. The hoist assembly is connected to the mobile power supply 5 via a first power line 11, and the fan 20 is connected to the mobile power supply 5 via a second power line 19. The mobile power supply 5 can be used by the electric hoist 6 and the axial flow fan throughout the rescue process, avoiding the need to run power lines from the maintenance power box as in traditional rescue methods, which not only delays rescue time but also affects the speed of rescue due to the large amount of debris at the scene.

[0043] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
