Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain storage depot leveling operation technology, and in particular to an explosion-proof leveling robot. Background Technology
[0002] Existing grain silo robot shells typically use simple bolt-locking connections, lacking specialized positioning and guiding mechanisms. This makes it difficult to quickly and accurately align the upper and lower shells during assembly, resulting in low assembly efficiency and a high risk of misalignment. Furthermore, the sealing design of existing shells is relatively simplistic, usually only using a single-layer sealing ring at the joints, often neglecting the sealing of positioning holes and complex support structures. In the harsh environment of grain silos with high dust and humidity, this structure is highly susceptible to dust explosions or moisture seeping into the interior through gaps in the positioning holes or shell edges. This can cause moisture damage to internal precision electronic components, leading to short circuits or other damage, thus reducing the robot's lifespan and reliability. Utility Model Content

[0028] This utility model discloses an explosion-proof warehouse leveling robot, which mainly includes a shell assembly, a positioning mechanism, and a sealing assembly. The shell assembly consists of an upper shell and a lower shell, which are detachably connected to form a cavity for accommodating internal components. Structurally, both the upper and lower shells include a shell body extending along a first direction and a support arm extending from the body and positioned opposite each other along a second direction. This support arm design better adapts to the robot's internal transmission mechanism or wheel layout, while also providing a more stable support surface for the shell connection. To achieve rapid assembly of the upper and lower shells, a positioning mechanism is provided. This mechanism includes a first positioning element on one shell and a first positioning mating element on the other shell. Before locking, the upper and lower shells are spatially positioned to prevent misalignment during assembly. For protection, the sealing assembly includes a first sealing element and a second sealing element. At least two first sealing elements are spaced apart and fitted around the outer periphery of the positioning element. This multi-seal structure effectively prevents dust or moisture from seeping in through the gaps in the positioning holes. The second sealing element extends circumferentially along the contact surface of the upper and lower shells, and its shape perfectly matches the contours of the main body of the shell and the two arms, forming a continuous sealing barrier around the edge of the shell. This greatly improves the waterproof and dustproof performance of the explosion-proof leveling robot in high-dust grain silo environments, while ensuring ease of disassembly and maintenance. Conversely, the interior of the shell will not be affected by external dust accumulation, effectively cutting off the propagation path of an explosion and ensuring the safe operation of the explosion-proof leveling robot in high-risk working conditions, improving the explosion-proof effect and extending its service life. Furthermore, the main body of the shell is divided into a combination of a first main body component and a second main body component, with gradually downward-sloping inclined surfaces at both ends. This design gives the robot's head and tail a smooth ramp shape, breaking away from the rigid structure of traditional box-like structures and helping to reduce travel resistance and prevent the accumulation of dust or particulate matter on the top of the shell. This solution, by adopting a streamlined shell design with inclined surfaces at both ends, effectively reduces the resistance of the robot when moving on the grain surface and prevents dust accumulation. At the same time, by combining a circumferential second seal that matches the shape of the support arm and multiple first seals fitted around the outer periphery of the first positioning member, a dual sealing system is constructed. Combined with the precise alignment achieved by the positioning mechanism, this significantly improves the robot's explosion-proof performance and sealing reliability. Attached Figure Description

[0042] This utility model proposes an explosion-proof warehouse leveling robot.
[0043] Reference Figures 1 to 7 In this embodiment of the utility model, an explosion-proof warehouse clearing robot includes:
[0044] The housing assembly 10 includes an upper housing 11 and a lower housing 12, which are detachably connected. Both the upper housing 11 and the lower housing 12 include a housing body 13 extending along a first direction and a support arm 14 connected to the housing body 13 and extending in opposite directions along a second direction, wherein the first direction and the second direction intersect.
[0045] The positioning mechanism 20 includes at least one first positioning member 21 disposed on one of the upper housing 11 and the lower housing 12, and a first positioning mating member 22 disposed on the other, wherein the first positioning member 21 and the first positioning mating member 22 cooperate to enable a detachable connection between the upper housing 11 and the lower housing 12.
[0046] The sealing assembly 30 includes a first sealing element 31 and a second sealing element 32. The number of first sealing elements 31 is at least two and they are spaced apart and sleeved on the outer periphery of the first positioning element 21. The second sealing elements 32 extend circumferentially along the abutment surface of the upper housing 11 and the lower housing 12, and the shape of the second sealing elements 32 is adapted to the shape of the housing body 13 and the two arms 14.
[0047] The main body 13 includes a first main body 131 and a second main body 132; the support arm 14 includes a first support arm 141 and a second support arm 142; the upper shell 11 includes a first main body 131 and a first support arm 141 connected to both sides of the first main body 131 and arranged opposite to each other; the lower shell 12 includes a second main body 132 and a second support arm 142 connected to both sides of the second main body 132 and arranged opposite to each other.
[0048] The first main body 131 includes a first main body portion 1311 and a first end 1312 and a second end 1313 disposed opposite to each other along a first direction from the first main body portion 1311. The first end 1312 is constructed with a first inclined surface 1314 that gradually slopes downward from the first main body portion 1311, and the second end 1313 is constructed with a second inclined surface 1315 that gradually slopes downward from the first main body portion 1311.
[0049] The second main body 132 includes a second main body portion 1321 and a third end 1322 and a fourth end 1323 disposed opposite to each other along a first direction from the second main body portion 1321. The third end 1322 is constructed with a third inclined surface 1324 that gradually slopes downward from the second main body portion 1321, and the fourth end 1323 is constructed with a fourth inclined surface 1325 that gradually slopes downward from the second main body portion 1321.
[0050] This utility model provides an explosion-proof warehouse robot. The shell assembly 10 constitutes the external skeleton and protective shell of the explosion-proof warehouse robot, mainly composed of an upper shell 11 and a lower shell 12. The upper shell 11 and the lower shell 12 are detachably connected, together forming a sealed housing space for accommodating the core components of the explosion-proof warehouse robot, such as internal electronic components, sensors, drive modules, and power supplies. This split design facilitates the assembly, internal maintenance, and component replacement of the explosion-proof warehouse robot. Furthermore, both the upper shell 11 and the lower shell 12 include a shell body 13 extending along a first direction (usually referring to the longitudinal main axis of the explosion-proof warehouse robot), which is the main compartment for accommodating the core components. At the same time, both the upper shell 11 and the lower shell 12 also include a support arm 14 connected to the shell body 13 and extending along a second direction (usually referring to the transverse direction). The main body 13 forms the main torso of the explosion-proof leveling robot, while the side arms 14 extend outwards, providing a wider support base for the robot or for mounting other functional components, such as wheels that contact the grain surface, sensor brackets, etc. To achieve rapid positioning and connection between the upper housing 11 and the lower housing 12, this application also includes a positioning mechanism 20. This positioning mechanism 20 includes at least one first positioning element 21 and a corresponding first positioning mating element 22. Specifically, the first positioning element 21 can be disposed on the inner surface of the upper housing 11, while the first positioning mating element 22 is located at the corresponding position on the lower housing 12. Of course, their positions can also be interchanged. In this application, the structural forms of the first positioning element 21 and the first positioning mating element 22 are not limited to specific geometric shapes, as long as they can form a sealed interface through abutment. Therefore, the first positioning element 21 includes, but is not limited to, a cylindrical positioning pin, while the first positioning mating element 22 is a positioning hole with a clearance fit or interference fit to the positioning pin. When the upper housing 11 and the lower housing 12 are assembled, the operator only needs to align the first positioning member 21 and insert it into the first positioning mating member 22 to complete the initial positioning of the two housings. This effectively prevents misalignment during assembly and facilitates the subsequent fastening of fasteners (such as screws), ensuring the structural stability of the connection. Given that explosion-proof leveling robots typically operate in grain silo environments with high dust concentrations and large humidity variations, their sealing performance is crucial. Therefore, this application also designs a sealing assembly 30, which employs a double-sealing structure to provide an excellent level of protection. The first seal surrounds the positioning mechanism 20. At least two first sealing members 31 are spaced apart around the outer periphery of the first positioning member 21. The structure of the first sealing member 31 is not limited to a specific geometry, as long as it can form a sealing interface through abutment. Therefore, the first sealing member 31 includes, but is not limited to, O-ring rubber seals.When the upper housing 11 and the lower housing 12 are engaged, the first positioning member 21 passes through the first seal 31 and enters the first positioning mating member 22. The first seal 31 is compressed axially, resulting in elastic deformation, thereby forming a radial seal between the hole walls of the first positioning member 21 and the first positioning mating member 22. The arrangement of at least two spaced first seals 31 provides a better sealing effect, greatly extending the penetration path of dust or moisture and significantly improving the sealing reliability of the positioning point, a potential leakage channel. The second seal acts on the entire contact surface of the upper housing 11 and the lower housing 12. A continuous second seal 32 extends circumferentially along the entire contact surface of the upper housing 11 and the lower housing 12. The shape of the second seal 32 is perfectly adapted to the contour of the housing body 13 and the two side arms 14, forming a complete and closed sealing loop. When the upper housing 11 and the lower housing 12 are closed, the second seal 32 is compressed between the abutting surfaces of the upper housing 11 and the lower housing 12, forming a primary sealing barrier that effectively prevents impurities from the external environment from invading the interior through the housing seams. The second seal 32 can also be made of sealing materials with good elasticity and aging resistance, such as rubber or silicone. The explosion-proof leveling robot of this application achieves rapid assembly of the upper housing 11 and the lower housing 12 through the positioning mechanism 20, and strengthens the sealing treatment through the double sealing assembly 30 composed of the first seal 31 and the second seal 32, thereby ensuring the high sealing performance and high reliability of the entire housing assembly 10 under harsh working conditions, and providing effective protection, dustproof and waterproof protection for the internal precision electronic components. In the flammable and explosive grain warehouse environment, dust explosion requires three elements: combustible material, oxidizer, and ignition source. This application, through a tight sealing structure, better physically isolates the electronic components (such as motors, circuit boards, and batteries) inside the explosion-proof leveling robot that may generate electric sparks or high temperatures from the hazardous external dust-filled environment. Even if an electrical fault occurs inside the explosion-proof warehouse leveling robot, generating sparks, the sealing component 30 prevents external flammable dust from entering the casing and contacting an ignition source. Conversely, the interior of the casing will not accumulate external dust, effectively cutting off the propagation path of an explosion. This ensures the safe operation of the explosion-proof warehouse leveling robot under high-risk conditions, improving explosion-proof performance and extending its service life.
[0051] Specifically, the main body 13 and the support arms 14 are not integrally formed single components. The upper shell 11 is composed of a first main body 131 and first support arms 141 connected to its two sides, while the lower shell 12 is composed of a second main body 132 and second support arms 142 connected to its two sides. This split design not only facilitates mold forming and internal assembly but also provides a basis for subsequent sealing and maintenance. Specifically, the first main body 131 (i.e., the main body of the upper shell 11) has a first end 1312 and a second end 1313 along a first direction (usually the direction of travel of the explosion-proof flatbed robot). At the first end 1312, a first inclined surface 1314 is constructed, which gradually slopes downward from the top of the first main body 1311. Correspondingly, at the second end 1313, a second inclined surface 1315 is constructed, also sloping downward from the first main body 1311. This design gives the upper shell 11 a streamlined appearance similar to a roof ridge or wedge at both ends. Correspondingly, the second main body 132 (i.e., the main body portion of the lower housing 12) has opposing third ends 1322 and fourth ends 1323 along the first direction. At the third end 1322, a third inclined surface 1324 is constructed, sloping downwards from the second main body portion 1321. At the fourth end 1323, a fourth inclined surface 1325 is constructed, also sloping downwards from the second main body portion 1321. When the upper housing 11 and lower housing 12 are closed and assembled, the first inclined surface 1314 and the third inclined surface 1324 are joined together at the front end (one end in the first direction) of the explosion-proof leveling robot to form a complete and continuous front guide slope. The second inclined surface 1315 and the fourth inclined surface 1325 are joined at the rear end (the other end in the first direction) of the explosion-proof leveling robot to form a rear guide slope. The inclined surfaces effectively guide dust, grain particles, or condensate in the grain silo to slide off, preventing accumulation on the top of the explosion-proof leveling robot, thereby reducing the frequency of cleaning and maintenance. Secondly, the streamlined appearance reduces the resistance of the explosion-proof leveling robot when moving on grain surfaces, especially when traversing soft grain piles. The sloping structure can play a certain role in breaking ice or guiding grain, preventing the explosion-proof leveling robot from getting stuck. This application adopts a streamlined shell design with sloping surfaces at both ends, which effectively reduces the resistance of the robot when moving on grain surfaces and prevents dust accumulation. At the same time, combined with the circumferential second seal 32 adapted to the shape of the support arm and multiple first seals 31 sleeved on the outer periphery of the first positioning member 21, a double sealing system is constructed. With the precise alignment achieved by the positioning mechanism 20, the explosion-proof performance and sealing reliability of the explosion-proof leveling robot are significantly improved.
[0052] Reference Figures 1 to 7In this embodiment of the present invention, the positioning mechanism 20 further includes a second positioning member 23, and a second positioning mating member 24 is provided on the third inclined surface 1324 and / or the fourth inclined surface 1325. The second positioning member 23 and the second positioning mating member 24 cooperate with each other, and the outer peripheral surface of the second positioning member 23 is configured to form an inclined mating surface that is adapted to the inner wall surface of the third inclined surface 1324 and / or the fourth inclined surface 1325.
[0053] The explosion-proof flattening robot's main body 13 has downward-sloping ramps at both ends (i.e., the first end 1312 and the third end 1322, the second end 1313 and the fourth end 1323) (such as the third inclined surface 1324 and the fourth inclined surface 1325). Therefore, this application introduces a matching scheme between a second positioning element 23 and a second positioning mating element 24 in the positioning mechanism 20. Specifically, the second positioning mating element 24 is provided on the third inclined surface 1324 and / or the fourth inclined surface 1325 (i.e., the inclined areas at both ends of the lower housing 12). Correspondingly, the second positioning element 23 is positioned on the corresponding inclined surface of the upper housing 11 (i.e., on the first inclined surface 1314 and / or the second inclined surface 1315). Unlike traditional cylindrical pins, the outer peripheral surface of the second positioning component 23 is not perpendicular to the mounting surface. Instead, it is specially constructed with an inclined mating surface adapted to the inner wall surface (i.e., the hole wall or mounting countersunk surface) of the third inclined surface 1324 and / or the fourth inclined surface 1325. The axis of the second positioning component 23 is perpendicular to the inclined surface, or its contact surface is parallel and in contact with the inclined surface. When the upper housing 11 and the lower housing 12 are assembled, the second positioning component 23 can smoothly slide into and tightly embed into the second positioning mating component 24 located on the inclined surface. This inclined surface-to-inclined surface adaptation design ensures that the positioning component and the hole wall can achieve surface contact rather than point contact in the inclined area, which greatly improves the stability and shear resistance of the connection and prevents the housing of the explosion-proof leveling robot from being misaligned when the grain surface is bumpy. Secondly, this tight inclined fit can effectively block external dust and moisture from entering the interior through the positioning hole gap at the inclined joint, complementing the first sealing component 31 and further improving the protection level (IP rating) of the whole machine in harsh grain storage environments. This structure also effectively increases the resistance to gas leakage. Even in extreme cases of internal micro-explosion, this inclined interlocking structure provides additional mechanical support, preventing the joint between the upper shell 11 and the lower shell 12 from being breached by high-pressure gas, thereby confining the explosion within the upper shell 11 and the lower shell 12 and preventing the ignition of dust clouds in the external environment. It is understood that the second positioning element 23 and the second positioning mating element 24 can be structurally represented as a wedge block and a wedge groove mating structure. The second positioning element 23 is a wedge-shaped boss protruding from the shell connection surface, with inclined mating surfaces machined on its two sides or one side of the outer peripheral surface. The second positioning mating element 24 is a wedge-shaped groove formed on the third inclined surface 1324 or the fourth inclined surface 1325. The inner wall of the groove has a guide slope consistent with the slope of the boss. During assembly, the two achieve self-locking and positioning through the wedge-tightening action of the inclined surfaces. Alternatively, both can be designed as a matching structure of a tapered pin and a tapered hole. In this case, the second positioning part 23 is a conical or pyramidal pin with its outer circumferential surface being an inclined mating surface, while the second positioning mating part 24 is a matching tapered countersunk hole, utilizing the characteristics of the tapered surface to eliminate assembly gaps.Regardless of its specific form, the core feature of the second positioning member 23 is that its outer peripheral surface must be constructed with an inclined mating surface that can form a surface contact with the inner wall surface (or extended surface) of the third inclined surface 1324 or the fourth inclined surface 1325. Through the mutual abutment and guidance between the inclined surfaces, it assists the first positioning member 21 in further positioning after positioning during the shell closing process, and effectively prevents the shell assembly 10 from loosening or misaligning under vibration. In this embodiment of the present invention, the outer surface of the bottom wall of the lower shell 12 is provided with a plurality of spaced ribs 1326, which extend along the first direction. The purpose of providing a plurality of spaced ribs 1326 extending along the first direction on the outer surface of the bottom wall of the lower shell 12 is primarily to enhance the structural rigidity and impact resistance of the shell assembly 10. Explosion-proof flatbed robots may face complex ground environments and potential collision risks during operation. As a component that directly contacts or is close to the ground, the bottom wall is highly susceptible to external impact. The addition of ribs 1326 is equivalent to constructing a reinforcing skeleton on the bottom wall of the lower housing 12, which can effectively disperse and absorb external impact forces, preventing deformation or damage to the housing assembly 10, thereby protecting the internal electrical components. Secondly, this design helps optimize heat dissipation performance. Ribs 1326 increase the outer surface area of the bottom wall of the lower housing 12, which is equivalent to adding a set of heat dissipation fins to the housing assembly 10. When internal heat is conducted to the bottom wall of the lower housing 12 through the housing assembly 10, the increased surface area can more effectively exchange heat with the outside air, assisting the internal airflow circulation device in heat dissipation, especially under high load conditions, which can further reduce the overall temperature of the machine.
[0054] Reference Figures 1 to 7 In this embodiment of the present invention, the sealing assembly 30 further includes a third sealing member 33, and the number of the third sealing members 33 is at least two and they are spaced apart and sleeved on the outer periphery of the second positioning member 23;
[0055] The outer wall of the second positioning member 23 is also provided with a guide positioning part, and the inner wall of the second positioning mating member 24 is provided with a positioning groove that is adapted to the guide positioning part.
[0056] A third sealing element 33 is added to the sealing assembly 30. Specifically, at least two third sealing elements 33 are spaced apart and fitted around the outer periphery of the second positioning element 23 (i.e., the positioning pin or boss set on the inclined surface of the upper housing 11). The structure of the third sealing element 33 is not limited to a specific geometry, as long as it can form a sealing interface through abutment. The third sealing element 33 is preferably a corrosion-resistant and aging-resistant O-ring rubber seal. Unlike planar seals, since the second positioning element 23 is located on an inclined surface, these sealing rings are subjected to axial compressive force during assembly, thereby forming a tight radial expansion seal between the second positioning element 23 and the hole wall of the second positioning mating element 24. The provision of at least two spaced third sealing elements 33 creates multiple lines of defense along the length of the positioning element. Even if one sealing ring fails slightly due to wear or impurities, the remaining sealing rings can still maintain the sealing effect. This redundant design greatly improves the explosion-proof rating, ensuring that external flammable and explosive dust cannot seep into the housing through the gaps in the positioning holes. To further ensure accuracy and stability during the inclined plane fitting process and prevent the positioning component from loosening or rotating due to vibrations during the operation of the explosion-proof leveling robot, this application also features a guide positioning part on the outer wall of the second positioning component 23 and a matching positioning groove on the inner wall of the second positioning mating component 24. The guide positioning part includes, but is not limited to, convex ribs, keyways, or spiral guide grooves extending axially along the positioning component, while the positioning groove is a groove structure matching its shape. As long as the two can form a guiding and circumferential limiting effect through the concave-convex fit, it is acceptable. When the upper housing 11 and lower housing 12 are closed, the guide positioning part first slides into the entrance of the positioning groove, acting as a guide to smoothly guide the second positioning component 23 into the second positioning mating component 24, avoiding assembly deviations caused by the inclined plane angle. Once assembled, the guide positioning part and the positioning groove are fully engaged, forming a circumferential limiting effect (i.e., an anti-torsion structure). This structure not only restricts the rotational freedom of the positioning component relative to the hole but also provides additional axial holding force, preventing the positioning component from loosening under high-frequency vibrations in the grain silo environment. This structure not only ensures the structural rigidity of the shell under complex stress, but also improves the safe operation of the explosion-proof flatbed robot in an explosion-proof environment through the dual means of physical isolation and mechanical locking.
[0057] Reference Figures 1 to 7In this embodiment of the invention, the explosion-proof flatbed robot further includes a drive mechanism 40, which includes a reduction gearbox assembly 41, a walking wheel assembly 42, and a drive assembly 43. The reduction gearbox assembly 41 includes two oppositely arranged reduction gearboxes 411, which are correspondingly arranged at the two second arms 142. The walking wheel assembly 42 includes two oppositely arranged walking wheels 421. The drive assembly 43 includes two oppositely arranged drive members 431. The two drive members 431 are correspondingly arranged at the second arms 142, and the output shafts of the two drive members 431 are connected to the input ends of the two reduction gearboxes 411. The output ends of the two reduction gearboxes 411 are respectively connected to the two walking wheels 421, and are correspondingly arranged.
[0058] The gearbox assembly 41 comprises two independent and oppositely arranged gearboxes 411. These two gearboxes 411 are not randomly installed, but are fixedly mounted on the two second supports 142 on either side of the explosion-proof ballast robot in a one-to-one correspondence. This layout utilizes the structural strength of the supports, providing a stable mounting base for the gearboxes 411 and enabling them to effectively transmit power to the wheel assembly 42. Meanwhile, the wheel assembly 42 also includes two oppositely arranged wheels 421, which are the final actuators that directly contact the ground and generate driving force for the explosion-proof ballast robot. The drive assembly 43 is not a single unit, but also employs a two-opposite arrangement, i.e., it is equipped with two independent drive components 431. These two drive components 431 are also mounted on the second supports 142 in a one-to-one correspondence, closely fitting the mounting positions of the gearboxes 411. This design places the power source directly near the walking wheel 421, shortening the transmission chain and effectively reducing energy loss, mechanical vibration, and frictional heat caused by long-shaft transmission. This not only improves overall transmission efficiency but, more importantly, reduces temperature rise during equipment operation, thereby enhancing safety in explosion-proof environments. Secondly, by directly mounting the gearbox 411 and walking wheel 421 at the second support arm 142, the weight of the entire drive mechanism 40 can be directly transferred to the main frame of the explosion-proof leveling robot through the support arm structure. This optimizes force distribution, avoids cantilever beam-type load-bearing structures, and enhances the structural rigidity and stability of the walking wheel 421 when carrying heavy materials or walking on uneven warehouse surfaces. This prevents component deformation or jamming due to uneven force distribution, helps improve transmission efficiency, and optimizes the overall spatial layout. In terms of transmission connections, the output shaft of each drive component 431 is connected to the input end of the corresponding gearbox 411, inputting the high-speed rotational power generated by the drive component 431 into the gearbox 411. The gearbox 411 internally reduces power and increases torque through gear meshing to meet the demands of heavy-duty movement. The processed power is then output from the gearbox 411 and, again in a one-to-one correspondence, is transmitted to the wheels 421 on the same side, ultimately driving the wheels 421 to rotate, thus enabling the explosion-proof warehouse robot to move forward, backward, or turn. It is understood that the drive unit 431 can be a servo motor, explosion-proof stepper motor, hydraulic motor, or pneumatic motor—any power device capable of outputting rotational power. The drive unit 431 is acceptable as long as it has a compatible output shaft to establish a transmission connection with the input of the gearbox 411, can provide the torque and speed required for the explosion-proof warehouse robot to move, and its structural dimensions and installation method are compatible with the installation space at the second arm 142.
[0059] Reference Figures 1 to 7In this embodiment of the present invention, the sealing component 30 further includes a fourth sealing element 34. The fourth sealing element 34 is provided between the gearbox assembly 41 and the second support arm 142. The fourth sealing element 34 is arranged around the gearbox assembly 41 and is used to seal the gap between the gearbox assembly 41 and the second support arm 142.
[0060] In addition, the sealing assembly 30 also includes a fourth seal 34, which is disposed between the gearbox assembly 41 and the second support arm 142 and is arranged circumferentially around the gearbox assembly 41 to seal the gap between them. This sealing structure effectively prevents external dust and particles from entering the gearbox 411, while also preventing internal lubricating oil leakage, ensuring the long-term stable operation of the travel drive mechanism under harsh conditions. The structure of the fourth seal 34 is not limited to a specific geometry, as long as it can form a sealing interface through abutment. Therefore, the fourth seal 34 includes, but is not limited to, a rubber sealing ring.
[0061] Reference Figures 1 to 7 In this embodiment of the present invention, the end of the gearbox 411 is provided with a drive shaft 412, the end of the drive shaft 412 is provided with a first mounting notch 413 extending axially, and the two sides of the first mounting notch 413 are provided with opposing first snap-fit arms 414.
[0062] The end of the walking wheel 421 is provided with a connecting part 422 that cooperates with the drive shaft 412. The end of the connecting part 422 extends to form a second locking arm 423 that is disposed opposite to it. A second mounting notch 424 is formed between the two second locking arms 423.
[0063] The first locking arm 414 engages with the second mounting notch 424, and the second locking arm 423 engages with the first mounting notch 413, so that the gearbox 411 and the traveling wheel 421 engage alternately.
[0064] The drive mechanism 40 also includes a bushing 44, which is sleeved on the outside of the engagement point between the first snap-fit arm 414 and the second snap-fit arm 423.
[0065] The gearbox assembly 41 has a drive shaft 412 at its end. A first mounting notch 413 is formed axially at the end of the drive shaft 412, thereby forming a pair of opposing first locking arms 414 on both sides of the notch. Correspondingly, the end of the travel wheel 421 has a connecting portion 422. The end of the connecting portion 422 extends to form a pair of opposing second locking arms 423, and a second mounting notch 424 is defined between the two second locking arms 423. During assembly, an interlocking engagement method is adopted, that is, the first locking arms 414 are embedded in the second mounting notch 424 of the connecting portion 422, while the second locking arms 423 of the travel wheel 421 are embedded in the first mounting notch 413 of the drive shaft 412. This interlocking structure not only realizes the circumferential positioning and power transmission of the gearbox 411 and the travel wheel 421, but also effectively restricts the relative displacement between the two, enhancing the overall integrity and shear resistance of the connection. Furthermore, to further enhance the stability and durability of the connection, the wheel assembly 42 is also equipped with a bushing 44. This bushing 44 is fitted outside the area where the first snap-fit arm 414 and the second snap-fit arm 423 mesh. Through the radial restraint effect of the bushing 44, the snap-fit arms are prevented from deforming or disengaging under long-term vibration or heavy load conditions, thereby ensuring the safety and reliability of the wheel assembly 42 during operation. It can be understood that the connecting part 422 can be an annular flange, flange, or hollow bushing-like structure extending outward from the end of the wheel 421. Its core function is to provide a contact surface and mating space adapted to the drive shaft 412. The connecting part 422 can be an annular protrusion on the wheel body of the wheel 421. The end face or side wall of the protrusion is machined with a second snap-fit arm 423 and a second mounting notch 424. Its inner diameter is slightly larger than or equal to the outer diameter of the drive shaft 412 so as to accommodate the insertion of the drive shaft 412 during assembly. The connecting part 422 can also be designed as a split structure, consisting of two semi-circular clamping blocks or clamps, which are locked to the end of the walking wheel 421 by fasteners. Its inner surface forms a driving surface complementary to the drive shaft 412. Regardless of the specific form, the geometry of the connecting part 422 must ensure that its second clamping arm 423 has sufficient shear strength to withstand the driving torque during the walking and leveling operations of the explosion-proof leveling robot. At the same time, its overall contour must maintain a smooth transition with the end face of the drive shaft 412 to match the installation of the bushing 44, forming a compact and sealed structure.
[0066] Reference Figures 1 to 7 In this embodiment of the present invention, the top of the upper housing 11 is also provided with a handle assembly 50, which includes two handles 51 that are spaced apart and arranged opposite to each other along the second direction.
[0067] The housing assembly 10 also includes a battery compartment for installing a battery 60. Two handles 51 are located on either side of the battery compartment along the second direction, so that the battery 60 is located between the two handles 51.
[0068] The handle assembly 50 does not employ a traditional single horizontal handle, but rather includes two independent handles 51 spaced apart and positioned opposite each other along a second direction (i.e., the width or lateral direction of the explosion-proof ballast robot). These two handles 51 are fixedly mounted on the top surface of the upper housing 11, providing operators with a stable gripping point for easy handling, hoisting, or repositioning of the explosion-proof ballast robot. The housing assembly 10 integrates a dedicated battery compartment for accommodating and securing the battery 60. In terms of spatial layout, the two handles 51 are positioned on the outer edges of this battery compartment along the second direction, ensuring that the battery compartment and the battery 60 installed inside are positioned precisely between the two handles 51 in a horizontal projection. This design leverages the battery 60's low center of gravity and relatively large mass, placing the handles 51 on either side of the battery 60. This ensures that when the operator lifts the explosion-proof ballast robot, the force application points are located above and to the sides of the center of gravity, significantly improving balance and stability during handling and preventing swaying caused by a shift in the center of gravity. Secondly, this layout is compact and reasonable, making effective use of the limited space at the top of the housing assembly 10. It ensures the ease of operation of the handle assembly 50 and provides sufficient and reasonable space for the internal battery compartment, making reasonable use of the space.
[0069] Reference Figures 1 to 7 In this embodiment of the utility model, the explosion-proof flatbed robot also includes a charging port and a fixing component 70. The tail of the upper shell 11 is provided with a first mounting hole 111, and the tail of the lower shell 12 is provided with a second mounting hole 121. The first mounting hole 111 and the second mounting hole 121 are connected to form an installation channel.
[0070] The fastener 70 passes through the mounting channel to securely connect the upper housing 11 and the lower housing 12.
[0071] The upper housing 11 and the lower housing 12 cooperate to form a receiving space, and the charging port is located at one end of the receiving space near the fixing member 70.
[0072] Specifically, this design features a first mounting hole 111 at the tail of the upper housing 11 of the explosion-proof flattening robot, and a second mounting hole 121 at the corresponding position on the lower housing 12. When the upper housing 11 and lower housing 12 are closed and assembled, these two mounting holes align and connect, forming a through mounting channel. A fastener 70 passes through this mounting channel, mechanically securing the upper housing 11 and lower housing 12 tightly at the tail. This design not only ensures the overall structural strength of the housing assembly 10 and prevents the housing from loosening during operational vibrations, but also serves to position the upper housing 11 and lower housing 12. Simultaneously, the upper housing 11 and lower housing 12 internally cooperate to form a closed receiving space for accommodating internal components such as circuit boards, sensors, or cables. The charging port is specifically positioned within this receiving space near the fastener 70. This layout cleverly utilizes the internal space near the fixing point at the rear of the housing to house the charging interface. It provides excellent external protection for the charging port through the housing structure, preventing direct exposure to impacts or dust, while also ensuring the charging port's relatively fixed position and proximity to the external power input point. This facilitates internal wiring and external plugging / unplugging operations, achieving a compact integration of structural fixation and functional interface. It is understood that the fixing component 70 may include, but is not limited to, bolts, screws, pins, or tie rods, with the specific choice depending on the assembly process and force requirements. If a bolt or screw structure is used, the fixing component 70 typically includes a threaded portion and a head. The threaded portion passes through the mounting channel formed by the first mounting hole 111 of the upper housing 11 and the second mounting hole 121 of the lower housing 12, and is locked by a threaded engagement or a nut. If a pin structure is used, the fixing component 70 is a smooth cylindrical rod, with axial positioning achieved by using snap rings or riveting at both ends. If a tie rod structure is used, the fixing component 70 can be a long rod penetrating the housing, fixed at both ends by nuts or clips, suitable for applications requiring large preload or long-distance connections. Regardless of the form, the outer diameter of the fastener 70 should match the inner diameter of the mounting channel to ensure assembly accuracy and connection rigidity. Simultaneously, its head or end structure should facilitate tool operation or provide anti-loosening functionality to meet the structural stability requirements of the explosion-proof flattening robot under complex working conditions. Furthermore, the fastener 70 in this application has a frame structure, its main outline adapted to the outer periphery of the tail of the housing assembly 10. Specifically, it includes two side plates arranged vertically opposite each other and a connector connecting the two side plates, thus forming a semi-enclosed or fully enclosed annular snap-fit space. The inner surface of the side plates has through holes corresponding to the first mounting hole 111 of the upper housing 11 and the second mounting hole 121 of the lower housing 12. When the fastener 70 is fitted onto the tail of the housing assembly 10, fasteners (such as bolts) pass through the through holes of the side plates and screw into the first mounting hole 111 and the second mounting hole 121, thereby using the rigid support force of the fastener 70 to tightly press and fix the upper housing 11 and the lower housing 12 at the tail.In addition, the outer surface of the fixing member 70 is designed with several reinforcing ribs or grooves, which not only increases the structural strength of the component itself and prevents it from deforming under stress, but also plays a role in anti-slip, making the entire tail structure of the explosion-proof flattening robot more robust. The sealing assembly 30 also includes a fifth sealing member 35, which is located between the fixing member 70 and the mounting channel.
[0073] Reference Figures 1 to 7 In this embodiment of the utility model, the explosion-proof warehouse robot also includes a power button 80, an emergency switch 90, and a sensor. The power button 80, the emergency switch 90, and the sensor are located at one end of the upper housing 11 near the charging port.
[0074] The sealing assembly 30 also includes a sixth seal and a seventh seal. The sixth seal is disposed around the power button 80 and is located between the power button 80 and the upper housing 11. The seventh seal is disposed around the emergency switch 90 and is located between the emergency switch 90 and the upper housing 11.
[0075] Specifically, this design centrally arranges the power button 80, emergency switch 90, and sensors at the end of the upper housing 11 near the charging port (i.e., the tail area of the explosion-proof silo robot). This layout allows users to easily perform power-on, emergency power-off, or status detection operations during charging or maintenance. To ensure the explosion-proof silo robot's waterproof and dustproof performance in dusty environments such as grain silos, the sealing assembly 30 further includes a sixth seal and a seventh seal. The sixth seal is arranged around the power button 80 and the upper housing 11, and the seventh seal is arranged around the emergency switch 90 and the upper housing 11. This partial surrounding seal effectively blocks external dust or moisture from entering the housing through the button gaps, improving the reliability of electrical components. The structure of the sixth and seventh seals is not limited to a specific geometry, as long as they can form a sealing interface through abutment. Therefore, the fourth seal 34 includes, but is not limited to, a rubber sealing ring. It is understood that the explosion-proof silo robot also includes a dust cover, which is connected to the fixing member 70.
[0076] Reference Figures 1 to 7 In this embodiment of the utility model, the explosion-proof leveling robot also includes a grain pushing plate or a fine leveling mechanism 100, which is connected to the fixing member 70.
[0077] This solution also utilizes the fixing component 70 as a functional expansion interface, connecting the grain pushing plate or the leveling mechanism 100 to the fixing component 70. Due to the high-strength fastening characteristics of the fixing component 70, using it as the mounting base for the grain pushing plate or the leveling mechanism 100 not only eliminates the need for additional mounting brackets, reducing the number of parts and assembly costs, but also leverages the high rigidity of the connection between the fixing component 70 and the tail of the explosion-proof leveling robot's shell to ensure stable force distribution and prevent loosening when pushing grain or clearing obstacles. This achieves the dual effect of structural reuse and functional enhancement. The grain pushing plate typically refers to a relatively simple rigid plate structure used to directly push grain flow. The leveling mechanism 100 typically refers to a component with certain adjustment functions, possibly including an adjustable-angle scraper or roller, used to achieve higher precision grain surface leveling. The grain pushing plate of the grain pushing plate or the leveling mechanism 100 is directly or indirectly installed at the fixing component 70 of the explosion-proof leveling robot through a fixed connection. This connection method ensures the stability of the working device during operation, enabling it to effectively complete the actions of pushing, spreading, or scraping grain by relying on the structural support provided by the fixing component 70. This allows it to adapt to the needs of leveling operations at different stages and improve leveling efficiency and grain surface flatness.
[0078] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
