[0056] 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 scope of protection of the present utility model.

[0057] The core of this invention is to provide an explosion-proof excavator with high protection capabilities. Another core aspect of this invention is to provide an explosion-proof excavator system including the aforementioned explosion-proof excavator, which offers strong protection against explosions.

[0058] Please refer to Figure 1This utility model embodiment provides an explosion-proof excavator, including a vehicle body 1, an explosion-proof cab 2, a cylinder protection device 3, a power protection device 4, a slewing protection device 5, and a travel motor protection device 6. The explosion-proof cab 2 is located on the vehicle body 1; the cylinder protection device 3 is installed on each cylinder of the explosion-proof excavator to protect the corresponding cylinder; the power protection device 4 is located on the vehicle body 1 to protect the power system, hydraulic system, and electronic control system of the explosion-proof excavator; the slewing protection device 5 is located on the vehicle body 1 to protect the slewing support 53 of the explosion-proof excavator; and the travel motor protection device 6 is located on the drive wheel 62 of the vehicle body 1 to protect the travel motor of the explosion-proof excavator.

[0059] In other words, this utility model embodiment provides comprehensive explosion-proof protection for the cab, cylinders, power system, hydraulic system, electrical control system, slewing support 53, and travel motor by installing an explosion-proof cab 2 on the vehicle body 1, thereby enhancing the protection capability of the explosion-proof excavator. This significantly reduces the risk of accidental explosions and their derivative hazards during hazardous material handling, ensuring the safety of personnel and equipment and minimizing property losses.

[0060] Furthermore, in some embodiments, the protection capabilities of the explosion-proof cab 2, cylinder protection device 3, power protection device 4, slewing protection device 5, and travel motor protection device 6 at the front of the explosion-proof excavator are greater than or equal to the protection capabilities of the explosion-proof cab 2, cylinder protection device 3, power protection device 4, slewing protection device 5, and travel motor protection device 6 at the sides of the explosion-proof excavator; the protection capabilities of the explosion-proof cab 2, cylinder protection device 3, power protection device 4, slewing protection device 5, and travel motor protection device 6 at the sides of the explosion-proof excavator are greater than or equal to the protection capabilities of the explosion-proof cab 2, cylinder protection device 3, power protection device 4, slewing protection device 5, and travel motor protection device 6 at the top, bottom, and rear of the explosion-proof excavator.

[0061] In other words, this embodiment adopts a graded protection concept, providing different levels of explosion protection for different positions of the explosion-proof excavator. The explosion protection capability level of the front of the explosion-proof excavator for the explosion-proof cab 2, cylinder protection device 3, power protection device 4, slewing protection device 5, and travel motor protection device 6 is greater than or equal to the explosion protection capability level of the corresponding side of the explosion-proof excavator; the explosion protection capability level of the side of the explosion-proof excavator for the explosion-proof cab 2, cylinder protection device 3, power protection device 4, slewing protection device 5, and travel motor protection device 6 is greater than or equal to the explosion protection capability level of the corresponding top, bottom, and rear surfaces of the explosion-proof excavator.

[0062] For example, the explosion-proof cab 2, cylinder protection device 3, power protection device 4, slewing protection device 5, and travel motor protection device 6 each adopt Level I protection for the front part of the explosion-proof excavator; the explosion-proof cab 2, cylinder protection device 3, power protection device 4, slewing protection device 5, and travel motor protection device 6 each adopt Level II protection for the side part of the explosion-proof excavator; and the explosion-proof cab 2, cylinder protection device 3, power protection device 4, slewing protection device 5, and travel motor protection device 6 each adopt Level III protection for the top, bottom, and rear parts of the explosion-proof excavator. That is, this embodiment designs the explosion-proof levels of the explosion-proof cab 2, cylinder protection device 3, power protection device 4, slewing protection device 5, and travel motor protection device 6 according to the hierarchical protection concept of Level I protection for the front of the explosion-proof excavator, Level II protection for the left and right sides, and Level III protection for the top, bottom, and rear parts of the explosion-proof excavator. It should be noted that, in the embodiments of this utility model, the explosion protection level of Class I protection is greater than that of Class II protection, and the explosion protection level of Class II protection is greater than that of Class III protection.

[0063] This structure not only meets the explosion-proof requirements of the explosion-proof excavator in all directions, but also ensures that the structural strength of the explosion-proof excavator is reasonably distributed. This ensures that the operation of the explosion-proof excavator is not affected even if an accidental explosion occurs during the handling of hazardous materials, thereby greatly improving the safety and reliability of the explosion-proof excavator operation.

[0064] Furthermore, exemplarily, in this embodiment of the invention, the safety factor for Level I protection is 1.5 times, for Level II protection it is 1.2 times, and for Level III protection it is 1 time. A safety factor of 1 time is sufficient to ensure that explosive fragments and shock waves from hazardous materials do not penetrate the protective material. This ensures that the explosion-proof excavator is protected against explosive fragments and shock waves from all directions, providing sufficient protection and improving its safety and reliability. Moreover, using different protection levels for different directions of the explosion-proof excavator not only meets the overall protection requirements but also helps reduce its weight and improve product performance.

[0065] It should be noted that the above embodiments do not limit the specific structure of the power protection device 4, as long as it can protect the power system, hydraulic system and electronic control system of the explosion-proof excavator.

[0066] Please refer to Figure 2 In some embodiments, the power protection device 4 includes a tail cover protection device 41, a counterweight protection device 42, a fuel tank protection device 43, an electrical control box protection device 44, a platform protection device 45, and a bottom sealing plate protection device 46. The tail cover protection device 41 and the counterweight protection device 42 are both located on the upper platform of the vehicle body 1 and are used to jointly protect the power system and the power system's cooling system. The counterweight protection device 42 is located below the tail cover protection device 41. The fuel tank protection device 43 is located outside the fuel tank of the explosion-proof excavator and is used to protect the hydraulic system. The electrical control box protection device 44 is located on the upper platform and is used to protect the electrical control system. The platform protection device 45 is located on the outside of the upper platform and is used to protect the upper platform and the hydraulic pipelines and lines installed on the upper platform. The bottom sealing plate protection device 46 is located at the bottom of the upper platform and is provided with heat dissipation holes and maintenance windows.

[0067] In other words, this embodiment uses a tail cover protection device 41 and a counterweight protection device 42 to protect the power system and its cooling system. For example, the tail cover protection device 41 and the counterweight protection device 42 are installed at the rear of the upper platform to protect the power system and cooling system located at the rear of the upper platform. Furthermore, the protection level of the tail cover protection device 41 and the counterweight protection device 42 can be Level III. Additionally, this embodiment uses a fuel tank protection device 43 located outside the fuel tank of the explosion-proof excavator to protect the fuel and hydraulic system. For example, the protection level of the fuel tank protection device 43 is Level II. The electrical control box protection device 44 can be fixedly installed on the left front of the upper platform to protect the control system and hydraulic system located on the left front of the upper platform. The electrical control box protection device 44 can be Level I. The platform protection device 45 can be installed on the frame of the upper platform to protect the upper platform and its internal hydraulic lines and wiring. The platform protection device 45 can be implemented using the principle of frontal Level I protection and side Level II protection. The bottom sealing plate protection device 46 can adopt Level III protection. The heat dissipation holes of the bottom sealing plate protection device 46 can play a role in ventilation and heat dissipation, preventing the temperature of various components on the vehicle platform from getting too high. In addition, the maintenance window of the bottom sealing plate protection device 46 facilitates maintenance and repair of various components on the vehicle platform.

[0068] In addition, the above embodiments do not limit the specific installation methods of the tail cover protection device 41, counterweight protection device 42, fuel tank protection device 43, electrical control box protection device 44, platform protection device 45 and bottom sealing plate protection device 46, as long as their installation can be achieved.

[0069] To facilitate equipment maintenance, in some embodiments, the tail cover protection device 41 and the electrical control box protection device 44 are respectively detachably mounted on the vehicle platform.

[0070] In other words, the tail cover protection device 41 and the electrical control box protection device 44 in this embodiment can be moved separately, so that the tail cover protection device 41 and the electrical control box protection device 44 can be opened or closed separately, so that the internal equipment can be maintained and repaired by opening the tail cover protection device 41 and / or the electrical control box protection device 44 at any time.

[0071] For example, the counterweight protection device 42 is fixedly installed on the vehicle platform by bolts or the like.

[0072] Furthermore, such as Figure 3 As shown, in some embodiments, the platform protection device 45 includes at least two platform protection plates 451 with their ends sequentially connected. The platform protection plates 451 are detachably connected to the vehicle platform via a first fastener 452. The platform protection plates 451 are provided with protective members 453 for protecting the first fastener 452.

[0073] In other words, in this embodiment, the platform protection device 45 adopts a segmented modular design, using multiple platform protection plates 451 spliced ​​together to form the overall platform protection device 45. Furthermore, since the platform protection plates 451 are detachably connected to the vehicle platform via the first fastener 452, when a single platform protection plate 451 is damaged, a new platform protection plate 451 can be quickly replaced by disassembly, avoiding the need to dismantle and replace the entire platform protection device 45, thus facilitating maintenance of the platform protection device 45. Additionally, the first fastener 452 is protected by a protective component 453 to prevent damage to the first fastener 452 during hazardous material handling due to explosions or scratches, thus ensuring the safety and reliability of the first fastener 452 and consequently ensuring the replaceability of the platform protection plate 451.

[0074] For simplicity of structure, the first fastener 452 is, for example, a bolt, and the protective component 453 is a protective pressure post located around the head of the bolt. That is, the platform protective plate 451 is connected to the upper platform by bolts, and the head of the bolt is protected by the protective pressure post to ensure that the bolt is removable.

[0075] In addition, considering protection and design requirements, in some embodiments, the tail cover protection device 41, the counterweight protection device 42, and the electrical control box protection device 44 are all wrap-around structures; and / or, the platform protection device 45, the bottom sealing plate protection device 46, and the fuel tank protection device 43 are all hanging structures; and / or, the platform protection plate 451 of the platform protection device 45 is a bent wrap-around structure.

[0076] The tail cover protection device 41, counterweight protection device 42, and electrical control box protection device 44 adopt a wrap-around design, which ensures the overall aesthetics of the explosion-proof excavator while reducing its overall weight. The platform protection device 45, bottom sealing plate protection device 46, and fuel tank protection device 43 adopt a hanging structure, which is simple in structure and easy to install. The platform protection plate 451 has a bent wrap-around structure. For example, the platform protection plate 451 is formed by bending a bulletproof steel plate in one piece, and has a certain angle, which can disperse the impact force of explosive fragments and effectively reduce the damage from the explosion.

[0077] In addition, in order to improve ventilation and heat dissipation performance, such as Figure 4 As shown, in some embodiments, the tail cover protection device 41 is provided with a protective grille 411 for ventilation.

[0078] In other words, this embodiment takes into account the overall heat dissipation performance of the machine. Without compromising the protective performance of the tail cover protection device 41, it ensures air intake ventilation and heat dissipation by setting a protective grille 411 on the tail cover protection device 41. For example, protective grilles 411 are respectively set on both sides of the tail cover protection device 41.

[0079] In addition, the above embodiments do not limit the specific structure of the slewing protection device 5, as long as the slewing protection device 5 can play a protective role for the slewing support 53.

[0080] Please refer to Figure 5 In some embodiments, the slewing protection device 5 includes a first protective frame 51 and a second protective frame 52. The first protective frame 51 and the second protective frame 52 are joined together to form a protective ring. The protective ring surrounds the outer periphery of the slewing support 53. The first protective frame 51 faces at least the front of the explosion-proof excavator, and the second protective frame 52 faces at least the rear of the explosion-proof excavator. The protective capacity of the first protective frame 51 is greater than that of the second protective frame 52.

[0081] In other words, in this embodiment, the slewing protection device 5 utilizes a first protective frame 51 and a second protective frame 52 to form a protective ring. The inside of the protective ring is used to house the slewing support 53, thereby enclosing the slewing support 53 and providing all-around protection. Since the first protective frame 51 faces at least the front of the explosion-proof excavator and the second protective frame 52 faces at least the rear of the explosion-proof excavator, the protective capability of the first protective frame 51 is greater than that of the second protective frame 52, thus giving the slewing protection device 5 better overall protection capabilities. For example, the first protective frame 51 adopts Class I protection, and the second protective frame 52 adopts Class III protection; the first protective frame 51 and the second protective frame 52 can each be a semi-circular ring structure, which are then joined to form a circular ring. The first protective frame 51 and the second protective frame 52 can be installed on the undercarriage 54 using the second fastener 513, or they can be installed on the upper platform. The first protective frame 51 and the second protective frame 52 may each include a mounting base plate 511 and an arc-shaped protective plate 512. The mounting base plate 511 and the arc-shaped protective plate 512 can be welded and fixed. The mounting base plate 511 is used to connect with the undercarriage frame 54 and / or the upper platform. The arc-shaped protective plate 512 surrounds the outer periphery of the slewing support 53 and plays a protective role.

[0082] In addition, the above embodiments do not limit the specific structure of the explosion-proof cab 2, as long as the explosion-proof cab 2 has an explosion-proof function.

[0083] Please refer to Figure 6In some embodiments, the explosion-proof cab 2 includes a frame 21, a bulletproof plate 22, and a bulletproof window 23. The frame 21 is a frame structure. The bulletproof plate 22 is connected to the frame 21 and is used to close all sides of the frame 21. The bulletproof plate 22 is also provided with a window. The bulletproof window 23 is installed in the window.

[0084] Understandably, the explosion-proof cab 2 primarily protects the operating system. The frame 21 defines the main structure of the explosion-proof cab 2 and provides support and mounting for the bulletproof plates 22. The bulletproof plates 22 can be fixed to various surfaces of the frame 21 by welding or fasteners, and can be of Level III protection. The bulletproof window 23 serves as a protective structure for windows, providing protection while allowing light to pass through, facilitating observation of the interior of the explosion-proof cab 2. Additionally, the explosion-proof cab 2 is equipped with an operator's seat, which can serve as a redundant emergency operating seat for remotely controlled explosion-proof excavators.

[0085] In addition, the above embodiments do not limit the specific structure of the hydraulic cylinder protection device 3, as long as the hydraulic cylinder protection device 3 can protect the corresponding hydraulic cylinder.

[0086] Please refer to Figure 7 In some embodiments, the cylinder protection device 3 includes a cylinder barrel protection plate 31 and a cylinder rod protection plate 32. The cylinder barrel protection plate 31 is used to connect to the cylinder barrel of the corresponding cylinder. One end of the cylinder rod protection plate 32 is used to connect to the piston rod of the corresponding cylinder, and the other end of the cylinder rod protection plate 32 is slidably connected to the cylinder barrel protection plate 31. At least one of the cylinder barrel protection plate 31 and the cylinder rod protection plate 32 is a bent wrapping structure.

[0087] Understandably, explosion-proof excavators include various hydraulic cylinders such as boom cylinders, stick cylinders, bucket cylinders, and bulldozer blade cylinders. A corresponding cylinder protection device 3 can be installed at each cylinder to protect all cylinders of the explosion-proof excavator. The structure of the cylinder protection device 3 for each cylinder can be identical. The protection level of each cylinder protection device 3 can be Class I, providing sufficient protection for cylinders in all positions.

[0088] As can be seen, the cylinder protection device 3 adopts a two-stage sliding structure to accommodate the extension and retraction of the cylinder. Specifically, the cylinder barrel is provided with a first mounting seat, and the piston rod is provided with a second mounting seat 33. The cylinder barrel protection plate 31 is connected to the corresponding cylinder barrel through the first mounting seat, and the cylinder rod protection plate 32 is connected to the corresponding piston rod through the second mounting seat 33. In addition, the cylinder barrel protection plate 31 is provided with a positioning mounting seat 34, which can be connected to the cylinder barrel protection plate 31 through a third fastener 35. The cylinder rod protection plate 32 is slidably disposed in the slot of the positioning mounting seat 34 so that when the piston rod extends or retracts, the cylinder rod protection plate 32 slides with the piston rod in the slot, thereby realizing the sliding connection between the cylinder rod protection plate 32 and the cylinder barrel protection plate 31, ensuring that the piston rod can be protected during the extension and retraction process.

[0089] In addition, at least one of the cylinder barrel protection plate 31 and the cylinder rod protection plate 32 is a bent wrapping structure. It is understood that the bent wrapping structure can better adapt to the shape of the cylinder barrel and the piston rod, thereby providing more effective protection for the cylinder barrel and the piston rod.

[0090] In addition, the above embodiments do not limit the specific structure of the walking motor protection device 6, as long as the walking motor protection device 6 can protect the walking motor.

[0091] Please refer to Figure 8 In some embodiments, the travel motor protection device 6 includes a protective cover 61, one end of which is open and a mounting plate 611 is provided at the open end. The protective cover 61 covers the outer periphery of the travel motor of the explosion-proof excavator, and the mounting plate 611 is connected to the drive wheel 62 of the explosion-proof excavator.

[0092] In other words, this embodiment uses a protective cover 61 to shield the travel motor, thus protecting it from damage caused by an explosion and preventing the explosion-proof excavator from becoming unable to move normally. The protective cover 61 is mounted to the drive wheel 62 of the explosion-proof excavator via a mounting plate 611, with the drive wheel 62 providing support. The mounting plate 611 is fixed to the drive wheel 62 using a fourth fastener 63. The protective cover 61 also includes protective side plates 612 and a protective top plate 613. The mounting plate 611 and the protective top plate 613 can be welded and fixed to the protective side plates 612 respectively to form the protective cover 61. Furthermore, the protective cover 61 can provide Level II protection.

[0093] Please refer to Figure 9 In addition to the aforementioned explosion-proof excavator, this utility model also provides an explosion-proof excavator system including the explosion-proof excavator 10 disclosed in the above embodiments. The explosion-proof excavator system further includes a remote control device 20, which is used for personnel to remotely operate the explosion-proof excavator 10.

[0094] In other words, the focus of this embodiment is that by using the explosion-proof excavator 10 disclosed in any of the above embodiments, the explosion-proof excavator system includes at least the beneficial effects of the explosion-proof excavator 10, which will not be elaborated here.

[0095] In addition, the explosion-proof excavator system uses a remote control device 20 to remotely operate the explosion-proof excavator 10, so as to realize the remote control operation function of the operator on the explosion-proof excavator 10 in the installation area, thereby ensuring the personal safety of the operator during the disposal of hazardous materials.
