Description

Technical Field

[0001] This utility model relates to the field of aerial work platform technology, specifically to an explosion-proof device for a diesel-powered aerial work platform. Background Technology

[0002] In certain working environments, such as those containing flammable and explosive gases, diesel-powered aerial work platforms may experience explosions due to electrical sparks generated during engine operation, posing significant safety hazards. Aerial work platforms are frequently used in flammable and explosive environments such as oil, chemical, and natural gas plants for equipment installation, maintenance, and other tasks. With the development of industrial production, the requirements for the explosion-proof performance of aerial work platforms are becoming increasingly stringent. They must not only effectively prevent explosions but also ensure that the normal operational functions and performance of the vehicle are not affected while maintaining explosion protection.

[0003] Currently, the explosion-proof devices for diesel-powered aerial work platforms are not yet perfect, failing to effectively prevent the explosion hazards caused by engine operation and making it difficult to meet the safety requirements for operation in hazardous environments. The generator, under continuous operation, is prone to excessive internal pressure, and during use, static electricity generated by the surrounding magnetic field can lead to fire. Furthermore, the lack of fire extinguishing devices allows small fires to escalate into large fires, potentially igniting nearby explosive materials and causing explosions, resulting in severe economic losses and even casualties. Therefore, we propose an explosion-proof device for diesel-powered aerial work platforms. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 An explosion-proof device for a diesel-powered aerial work platform includes a mounting base 1, an explosion-proof housing 2 fixedly mounted on the top of the mounting base 1, a limit groove 3 formed on the top of the explosion-proof housing 2, an explosion-proof steel pipe 4 installed inside the explosion-proof housing 2, a shock-absorbing pad 5 fixedly mounted on the bottom inside the explosion-proof housing 2, a support cover 6 fixedly mounted on the top of the explosion-proof housing 2, and an explosion-proof mechanism 7 installed on the top of the support cover 6. The explosion-proof mechanism 7 includes a pressure relief device and a fire extinguishing device. The operation of the pressure relief device drives the fire extinguishing device to protect the diesel-powered aerial work platform from explosion and extinguish any fires.

[0026] In this embodiment, the pressure relief device includes a connecting plate 701. A pressure sensing component 702 is fixedly installed on the top of the connecting plate 701. A connecting component 703 is fixedly installed on the outside of the pressure sensing component 702. A connecting pipe 704 is fixedly installed on the outside of the connecting component 703. An output component 705 is fixedly installed at the end of the connecting pipe 704 away from the connecting component 703. A pressure relief valve 706 is fixedly installed on the outside of the output component 705. A gas supply pipe 707 is connected through the outside of the pressure relief valve 706. A monitoring instrument 708 is fixedly installed on the outside of the pressure relief valve 706. A pressure relief port 709 is opened on the top of the pressure relief valve 706. By incorporating a pressure relief device, an explosion is prevented from occurring due to pressure buildup. Excessive pressure is released to avoid exceeding the container's or space's tolerance limits, thereby effectively reducing the likelihood of an explosion and ensuring the safety of the vehicle and its surrounding environment. The rapid and stable pressure relief process prevents excessive pressure from causing permanent damage to the tank, pipelines, compartments, and other components of the work vehicle. It ensures that the equipment maintains its basic structural integrity after the danger has passed, reducing maintenance costs and equipment downtime, and improving the service life and reliability of the work vehicle.

[0027] Furthermore, the fire extinguishing device includes a fire extinguishing component 711, a fire extinguishing connector 712 fixedly installed on the outside of the fire extinguishing component 711, a fire extinguishing nozzle 713 fixedly installed at the end of the fire extinguishing connector 712 away from the fire extinguishing component 711, and an anti-static mesh 710 fixedly installed on the inner wall of the explosion-proof housing 2. By incorporating the fire extinguishing device, it can be activated rapidly to extinguish fires in their initial stages, curbing the spread of fire and preventing small fires from developing into large-scale, uncontrollable fires. This buys valuable time for personnel evacuation and further firefighting and rescue efforts. Timely fire extinguishing maximizes the protection of critical components of the work vehicle from severe fire damage, reducing equipment repair or replacement costs caused by fire. It also minimizes damage to the surrounding work environment, other equipment, and buildings, reducing economic losses and potential casualties.

[0028] Furthermore, a connecting plate 701 is bolted to the top of the supporting cover 6, and a fire extinguishing component 711 is fixedly installed at the bottom inside the explosion-proof enclosure 2. The explosion-proof enclosure 2 is constructed of high-strength metal materials, such as cast steel or cast iron, which can withstand the pressure of an explosion without rupturing. The cover and the enclosure fit tightly together to ensure the enclosure's airtightness. Sealing gaskets and other components are typically used to enhance the sealing effect, preventing flames and high-temperature gases from an internal explosion from leaking into the external environment and causing danger.

[0029] Furthermore, the limiting groove 3 is compatible with the explosion-proof steel pipe 4, which is located inside the explosion-proof housing 2. The installation of the explosion-proof steel pipe 4 ensures that the surrounding area of ​​the explosion-proof housing 2 is evenly stressed, preventing the entire structure from collapsing due to uneven stress.

[0030] In addition, three identical sets of connecting components 703, connecting pipes 704, and output components 705 are provided, and all three sets of connecting components 703, connecting pipes 704, and output components 705 are located outside the pressure sensing component 702. Two identical sets of gas supply pipes 707 are provided, and the two sets of gas supply pipes 707 are symmetrically distributed about the vertical center line of the pressure relief valve 706. By providing connecting components 703, connecting pipes 704, and output components 705, the pressure sensing component 702 can transmit data to the pressure relief valve 706 in real time.

[0031] It is worth noting that the antistatic mesh 710 and the fire extinguishing component 711 do not come into contact with each other. Multiple sets of the same fire extinguishing connector 712 and fire extinguishing nozzle 713 are provided, and these multiple sets of fire extinguishing connectors 712 and fire extinguishing nozzles 713 are equidistantly distributed on the outside of the fire extinguishing component 711. By providing multiple sets of fire extinguishing connectors 712 and fire extinguishing nozzles 713, rapid activation is possible, enabling fire suppression in the early stages of a fire, containing its spread, preventing small fires from developing into large-scale, uncontrollable fires, and buying valuable time for personnel evacuation and further firefighting and rescue. Timely fire suppression maximizes the protection of critical components of the work vehicle from severe fire damage, reducing equipment repair or replacement costs caused by the fire, while also minimizing damage to the surrounding work environment, other equipment, and buildings, reducing economic losses and potential casualties.

[0032] In use, the operator fixes the pressure sensing component 702 to the support cover 6 via the connecting plate 701. Then, it is fixedly connected to the pressure relief valve 706 through three sets of connecting components 703, connecting pipes 704 and output components 705. This allows the pressure sensing component 702 to transmit data to the pressure relief valve 706 in real time, so that the monitoring instrument 708 on the pressure relief valve 706 can display the data. This releases the internal pressure of the explosion-proof housing 2, thus providing explosion protection for the whole structure. At the same time, the explosion-proof housing 2 is made of high-strength metal materials, such as cast steel and cast iron, which can withstand the pressure generated by an explosion without breaking. The cover and outer shell fit tightly together to ensure the airtightness of the outer shell. Sealing gaskets and other components are typically used to enhance the sealing effect, preventing the leakage of flames and high-temperature gases generated by an internal explosion into the external environment and causing danger. At this time, the worker places the explosion-proof steel pipe 4 within the limiting groove 3 of the explosion-proof outer shell 2, ensuring even force distribution around the explosion-proof outer shell 2 and preventing collapse due to uneven force. Furthermore, the anti-static mesh 710 effectively reduces electromagnetic interference inside the explosion-proof outer shell 2, preventing fires caused by high-speed operation of internal devices. The fire extinguishing connector 712 and fire extinguishing nozzle 713 allow for rapid activation, enabling fire suppression in the early stages of a fire, containing its spread, and preventing small fires from developing into large, uncontrollable fires. This buys valuable time for personnel evacuation and further firefighting and rescue efforts. Timely fire suppression maximizes the protection of critical components of the work vehicle from severe fire damage, reducing equipment repair or replacement costs caused by the fire. It also minimizes damage to the surrounding work environment, other equipment, and buildings, reducing economic losses and potential casualties.
