Technical Field

[0001] The present invention relates to the technical field of robots, and in particular to an emergency material transport robot. Background Art

[0002] Emergency supplies refer to the material guarantees necessary for the entire emergency response process to deal with sudden public events such as serious natural disasters, accidental disasters, public health incidents and social security incidents. These materials need to be carried by rescue workers during transportation. Long-term transportation will cause harm to the rescue workers' bodies and affect the efficiency of subsequent rescue.

[0003] With the continuous development of robot technology, in order to solve the above problems, automatic loading and unloading robots have appeared on the market at this stage. At present, most of the robots that can realize automatic unloading are large in size and cannot provide stronger maneuverability and flexibility. In addition, the environment in the disaster-stricken area is complex, and the delivery capacity of emergency materials is high. The transportation and distribution of emergency materials need to be fast and efficient to ensure that the necessary support is provided to the victims in the shortest time. It is necessary for the transport robot to quickly reach the disaster-stricken area, provide the necessary material support to the victims in time, and improve the delivery capacity of emergency materials. Therefore, based on the above problems, the present invention provides an emergency material transport robot to meet the needs. Summary of the invention

The above arrangement can solve the problem that most robots that can realize automatic unloading at this stage are large in size, cannot provide stronger maneuverability and flexibility, cannot provide necessary material support to disaster victims in time, and have low emergency material delivery capacity.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: An emergency material transport robot comprises a plate body, wherein clamping assemblies are symmetrically installed on both sides of the inner wall of the plate body, the clamping assemblies are used to fix emergency material boxes, and the clamping assemblies are connected to the plate body; and a lifting assembly, the lifting assembly is used to facilitate automatic unloading, and the lifting assembly is connected to the plate body.

[0007] Optionally, the inner side of the clamping piece is a curved elastic structure, and the top and bottom of the clamping piece both have an inward curvature.

[0008] Optionally, the support block has an upward curvature at a position close to the plate body, and the support block is in a horizontal state at a position close to the hollow groove.

[0009] Optionally, the clamping piece, the extending piece and the pulling rod are an integrally manufactured structure, and the plate body and the clamping piece are provided with grooves on one side close to the plate body, and the grooves correspond to the positions of the support blocks.

[0010] Optionally, the plate body is a U-shaped structure surrounded on three sides, an arc-shaped groove is opened at the center of the plate body, and oblique grooves are opened at the tops of both ends of the plate body.

[0011] Optionally, a limiting tube is slidably inserted into the bottom of the inner wall of the oblique groove, and a uniformly distributed weakening groove is provided at the bend of the limiting tube. The center of the limiting tube has an arc that bends toward the inside of the plate body.

[0012] Optionally, the lifting assembly includes a controller fixedly connected to the inside of the plate body, the controller is slidably connected to a lifting rod inside, the bottom of the lifting rod is fixedly connected to a lower pressure plate, the bottom of the lower pressure plate is fixedly connected to an inner airbag, the outer airbag is sleeved on the outside of the inner airbag, a connecting hole is provided on one side of the inner airbag, the internal cavities of the inner airbag and the outer airbag are connected through the connecting hole, and a contact surface is fixedly connected to the bottom of the outer airbag, and the contact surface is provided with evenly distributed arc-shaped anti-slip grooves.

[0013] Optionally, the inner airbag, the outer airbag and the contact surface are an integrally manufactured structure, the outer contour of the lower pressure plate matches the inner wall contour of the outer airbag, and the bottom of the lifting rod extends to the interior of the inner airbag.

[0014] Optionally, the top of the lifting rod is fixedly connected to the bottom of the limiting tube, and the bottom of the extending piece is fixedly connected to the top of the lower pressing plate.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting a clamping assembly and a lifting assembly, the clamping assembly and the lifting assembly are respectively arranged on the inner wall and the bottom of the plate body. The clamping assembly can not only clamp and fix the emergency material box, but also when the robot encounters bumps during the forward movement and the emergency material box moves down, it can further clamp and support the emergency material box, thereby ensuring that the emergency materials can be stable during the entire transportation process; the lifting assembly can not only buffer and stabilize the robot after it stops, but also pull the clamping assembly during the descent, thereby replacing manpower to realize automatic unloading of the emergency material box. Compared with manual unloading, such a setting is more efficient in automatic unloading, saves manpower and material resources, improves the transportation efficiency of emergency materials, maximizes time benefits, and improves the rapid delivery capability of emergency materials.

[0016] By setting a clamping plate, the overall contour of the clamping plate is a V-shaped structure and the inner side is provided with evenly distributed hollow grooves. The emergency material box is placed between the clamping plates by manpower. The dead weight of the emergency material box is utilized in combination with the elastic structure of the clamping plate whose arc increases from top to bottom. During the descent of the emergency material box, the clamping plate continuously clamps it to ensure the stability of the emergency material box. Evenly distributed hollow grooves are provided. The hollow grooves can not only increase the local flexibility of the plate body so that it can better adapt to deformation when subjected to force, but also the evenly distributed hollow grooves can reduce the amount of material used, thereby reducing the overall weight of the structure, improving the utilization rate of materials, reducing costs, and improving the practicality of the device.

[0017] By setting up support blocks and pulling rods, the support blocks are respectively arranged at the four corners of the inner wall of the plate body, and the support blocks are used to provide secondary protection for the emergency material box to prevent the clamping plate from being squeezed and deformed. The support blocks are used to support the four corners of the emergency material box to ensure that the emergency material box is safely delivered to the destination. The pulling rod can drive the support block to rotate, which is convenient for the robot to automatically unload after arriving at the destination. The support block is rotated by moving the pulling rod downward to release the limit on the emergency material box, ensuring that the emergency material box is smoothly transported to the destination. In addition, the clamping plate, extension plate and pulling rod are an integrated manufacturing structure. This setting makes the processing technology of the three simpler during the production process, easier to produce, and reduces the manufacturer's capital investment.

[0018] By setting a lifting rod, a lower pressure plate, an outer airbag and an inner airbag, when the lifting rod descends, the lower pressure plate squeezes the inner airbag, so that the air inside the inner airbag is squeezed into the cavity of the outer airbag, and the outer contour of the outer airbag is enlarged, thereby increasing the contact area between the contact surface and the ground. The inner airbag is flattened until it touches the bottom of the lifting rod, causing the lifting rod to rebound and rise to its initial state. With the help of the structural characteristics of the inner and outer airbags, not only can the contact area with the ground be increased, making the robot stable when unloading, but also the deformation of the inner airbag can be used to transmit pressure to the lifting rod, thereby achieving automatic recovery after unloading is completed, which is convenient for the next transportation work. Not only is the structure simple and ingenious, but the actual operation is convenient and labor-saving.

[0019] By setting a limit tube and an oblique groove, the limit tube has two states: before the lifting rod descends, the limit tube is located on the side of the plate opening, which can prevent the emergency material box from slipping off the tail of the transport robot; after the lifting rod descends, the lifting rod slides downward while the two ends of the limit tube move downward, and evenly distributed weakening grooves are provided at the bending part of the limit tube, which can reduce the rebound force of the limit tube after bending, so that the limit tube can be more easily straightened after bending, and the design of the weakening groove makes the bending and straightening operations of the limit tube more convenient; the setting of the oblique groove ensures that the two states of the limit tube can be switched freely, and it is also convenient for the limit tube to rebound smoothly after being straightened, ensuring all-round protection of the emergency material box during transportation.

The plate body 1 is a U-shaped structure surrounded by three sides, and an arc groove 3 is opened at the center of the plate body 1, and oblique grooves 101 (such as Figures 1 to 3As shown in the figure, the width dimension of the emergency material box is consistent with the distance between the tops of the two clamping pieces 2, the length dimension of the emergency material box is consistent with the length dimension of the inner wall of the plate body 1, and the height dimension of the emergency material box is consistent with the top height of the plate body 1. The size of the emergency material box is unified, which is convenient for better adaptation to the transport robot and ensures the smooth operation of the transport robot. The plate body 1 with three sides enclosed and one side open is set to ensure that the emergency material box can be clamped while facilitating automatic unloading from the opening. The arc groove 3 is opened at the top of the center of the plate body 1. The arc groove 3 is opened to facilitate manpower to place the emergency material box inside the plate body 1 without pinching the hands, leaving a position for the hand-held emergency material box. The oblique groove 101 facilitates the state switching of the limit tube 5. During transportation, the limit tube 5 is located on the side of the opening of the plate body 1 to prevent the emergency material box from falling off. When the automatic unloading is started, the limit tube 5 is driven 5 is straightened, and the height of the limit tube 5 exceeds the top of the emergency material box, which is convenient for the smooth descent of the emergency material box. By setting a clamping component and a lifting component, the clamping component and the lifting component are respectively arranged on the inner wall and the bottom of the plate body 1. The clamping component can not only clamp and fix the emergency material box, but also when the robot encounters bumps during the forward movement and the emergency material box moves down, it can further clamp and support the emergency material box, thereby ensuring that the emergency materials can be stable during the entire transportation process; the lifting component can not only buffer and stabilize the robot after it stops, but also pull the clamping component during the descent, thereby replacing manpower to realize automatic unloading of the emergency material box. Compared with manual unloading, such a setting has higher efficiency in automatic unloading, saves manpower and material resources, improves the transportation efficiency of emergency materials, maximizes time benefits, and improves the rapid delivery capability of emergency materials.

[0030] As an implementation method in this embodiment, Figures 1 to 5 As shown, the clamping assembly includes a clamping piece 2 fixedly connected to both sides of the inner wall of the plate body 1, and a linear array of hollow grooves 201 are opened on the clamping piece 2. A support block 4 is rotatably installed on the inner wall of the plate body 1, and the support block 4 corresponds to the position of the hollow grooves 201 at both ends. The bottom of the support block 4 is rotatably connected to a pulling rod 401, and the bottom of the pulling rod 401 is fixedly connected to the bottom of the hollow groove 201. The two ends of the bottom of the clamping piece 2 are fixedly connected to extension pieces 202. The clamping piece 2 The inner side is a curved elastic structure, the top and bottom of the clamping piece 2 are curved inward, the clamping piece 2, the extension piece 202 and the pulling rod 401 are an integrated manufacturing structure, the bottom of the extension piece 202 is fixedly connected to the top of the lower pressing plate 602, the side of the clamping piece 2 close to the plate body 1 is a straight structure, and is fixedly connected to the inside of the plate body 1, and the other side of the clamping piece 2 is a wavy curved surface structure from top to bottom, and the curved surface at the bottom is more convex than that at the top (such as Figure 5 As shown), the bottom spacing between the two clamping sheets 2 is greater than the top spacing between the two clamping sheets 2 (as shown Figure 2As shown in FIG. 2 ), the inner wall size of the hollow groove 201 is larger than the outer wall profile of the support block 4, and the support block 4 does not contact the inner wall of the hollow groove 201 during the entire rotation process, ensuring that the support block 4 is not restricted by the hollow groove 201. The extension pieces 202 at both ends of the bottom of the clamping piece 2 are curved structures and extend to the top of the lower pressing plate 602 (as shown in FIG. Figure 5 As shown in the figure, the clamping piece 2, the extension piece 202 and the pulling rod 401 are an integrated manufacturing structure. The integrated structure manufacturing can not only reduce the production cost, but also make the connection between each two planes more reliable, so that the overall structure has higher strength, and the construction process of the integrated structure is simple, which is easy to promote and apply. By setting the clamping piece 2, the overall contour of the clamping piece 2 is a V-shaped structure and the inner side is provided with evenly distributed hollow grooves 201. The emergency material box is placed between the clamping pieces 2 by manpower, and the dead weight of the emergency material box is used in combination with the elastic structure of the clamping piece 2 with an increasing arc from top to bottom. During the descent of the emergency material box, the clamping piece 2 continuously clamps it to ensure the stability of the emergency material box. Evenly distributed hollow grooves 201 are set. The hollow grooves 201 can not only increase the local flexibility of the plate body 1, so that it can better adapt to deformation when subjected to force, but also the evenly distributed hollow grooves 201 can reduce the amount of material used, thereby reducing the overall weight of the structure, improving the utilization rate of materials, reducing costs, and improving the practicality of the device.

[0031] In this embodiment, if Figure 5 and Figure 8 As shown, the support block 4 has an upward curvature near the plate body 1, and the support block 4 is in a horizontal state near the hollow groove 201. The plate body 1 and the clamping piece 2 are both provided with grooves on one side near the plate body 1, and the grooves correspond to the positions of the support block 4. One end of the support block 4 is rotatably connected to the inner wall of the groove through an aluminum-magnesium integrated rebound shaft, and the other end of the support block 4 is rotatably connected to the pulling rod 401 through a rotating shaft. When a downward pulling force is applied to the support block 4 through the traction rod, the support block 4 rotates downward around the aluminum-magnesium integrated rebound shaft. Once the downward pulling force disappears, the reset mechanism inside the aluminum-magnesium integrated rebound shaft is used to realize the reset of the support block 4 (such as Figure 8 As shown in FIG. 1 ), the internal structure and working principle of the aluminum-magnesium integrated rebound shaft are disclosed in the prior art and will not be described in detail here. The contact surface 701 between the support block 4 and the emergency material box is in a horizontal state (as shown in FIG. 1 ). Figure 5As shown), the contact surface 701 with the box body is increased to the maximum extent, so as to more stably support the emergency material box. By setting the support block 4 and the pulling rod 401, the support blocks 4 are respectively arranged at the four corners of the inner wall of the plate body 1, and the support blocks 4 are used to provide secondary protection for the emergency material box to prevent the clamping plate 2 from being squeezed and deformed. The support blocks 4 are used to support the four corners of the emergency material box to ensure that the emergency material box is safely delivered to the destination. The pulling rod 401 can drive the support block 4 to rotate, which is convenient for the robot to automatically unload after arriving at the destination. The support block 4 is rotated by moving the pulling rod 401 downward to release the limit on the emergency material box, so as to ensure that the emergency material box is smoothly transported to the destination. In addition, the clamping plate 2, the extension plate 202 and the pulling rod 401 are an integrated manufacturing structure. Such a setting makes the processing technology of the three simpler during the production process, easier to be manufactured, and reduces the manufacturer's capital investment.

[0032] As an implementation method in this embodiment, Figures 4 to 7As shown, the lifting assembly includes a controller 6 fixedly connected to the inside of the plate body 1, the inside of the controller 6 is slidably connected to a lifting rod 601, the bottom of the lifting rod 601 is fixedly connected to a lower pressure plate 602, the bottom of the lower pressure plate 602 is fixedly connected to an inner air bag 702, the outer air bag 702 is sleeved with an outer air bag 7, a connecting hole 703 is provided on one side of the inner air bag 702, the inner air bag 702 and the inner cavity of the outer air bag 7 are connected through the connecting hole 703, the bottom of the outer air bag 7 is fixedly connected to a contact surface 701, the contact surface 701 is provided with evenly distributed arc-shaped anti-skid grooves, the inner air bag 702, the outer air bag 7 and the contact surface 701 are an integrated manufacturing structure, the outer contour of the lower pressure plate 602 coincides with the inner wall contour of the outer air bag 7, and the lifting rod 60 1 extends to the inside of the inner airbag 702. When the robot reaches the destination according to the program, the controller 6 is automatically started. At this time, the lifting rod 601 slowly descends until the contact surface 701 touches the ground, and the lifting rod 601 stops descending. During the slow descent of the lifting rod 601, the lower pressure plate 602 drives the bottom of the extension piece 202 and the clamping piece 2 to stretch downward. While the clamping piece 2 is stretched and deformed, the traction rod also pulls the support block 4 downward, causing the support block 4 to rotate downward. At the same time, the limiting tube 5 is also straightened upward under the action of the lifting rod 601 to release the limit on the emergency material box. At this time, the clamping force of the clamping piece 2 on the emergency material box is slowly reduced, and the supporting force of the support block 4 on the emergency material box is also slowly reduced synchronously. The box slowly descends until it lands on the ground. Due to the deadweight of each structure, the lower pressure plate 602 continues to press down on the inner airbag 702. The inner airbag 702 is flattened until the bottom of the lifting rod 601 contacts the bottom of the inner wall of the inner airbag 702. At this time, the rising function of the controller 6 is triggered. At the same time, the transport robot starts the fast forward mode, and the emergency material box is separated from the transport robot to realize automatic unloading. Since the inner airbag 702 and the outer airbag 7 are connected to the internal cavity through the connecting hole 703, the inner airbag 702 is squeezed and transferred to the inside of the outer airbag 7, which increases the contact surface 701 with the ground. The contact surface 701 area of ​​the ground is increased, and the overall stability of the transport robot is improved. By setting the lifting rod 601, the lower pressure plate 602, the outer airbag 7 and the inner airbag 702, the lifting During the descent of the rod 601, the lower pressure plate 602 squeezes the inner airbag 702, so that the air inside the inner airbag 702 is squeezed into the cavity of the outer airbag 7, and the outer contour of the outer airbag 7 is enlarged, thereby increasing the contact surface 701 and the contact surface 701 area between the contact surface 701 and the ground. The inner airbag 702 is flattened until it touches the bottom of the lifting rod 601, causing the lifting rod 601 to rebound and rise to its initial state. With the help of the structural characteristics of the inner airbag 702 and the outer airbag 7, not only can the contact surface 701 area with the ground be increased, making the robot stable when unloading, but also the deformation of the inner airbag 702 can be used to transmit pressure to the lifting rod 601, thereby realizing automatic recovery after unloading is completed, which is convenient for the next transportation work. Not only is the structure simple and ingenious, but the actual operation is also convenient.

[0033] In this embodiment, if Figures 4 to 6 As shown, the top of the lifting rod 601 is fixedly connected to the bottom of the limiting tube 5, and the limiting tube 5 is slidably inserted into the bottom of the inner wall of the oblique groove 101. The bending part of the limiting tube 5 is provided with uniformly distributed weakening grooves 501. The center of the limiting tube 5 has an arc bent toward the inside of the plate body 1. The limiting tube 5 slides inside the plate body 1 and is fixedly connected to the top of the lifting rod 601, so that the lifting rod 601 is lowered and a downward pulling force is applied to the limiting tube 5, so that the limiting tube 5 is easily straightened under the action of the weakening groove 501. The inner hollow setting of the limiting tube 5 can reduce the dead weight of the material and save costs. The center of the limiting tube 5 is provided with an arc bent toward the emergency material box. In order to increase the buffering of the box body and keep the box body stable, a limiting tube is set 5 and oblique groove 101, the limiting tube 5 has two states: before the lifting rod 601 descends, the limiting tube 5 is located at the side of the opening of the plate body 1, which can prevent the emergency material box from slipping off the tail of the transport robot; after the lifting rod 601 descends, the lifting rod 601 slides downward while the two ends of the limiting tube 5 move downward, and the bending part of the limiting tube 5 is provided with uniformly distributed weakening grooves 501, which can reduce the rebound force of the limiting tube 5 after bending, so that the limiting tube 5 can be more easily straightened after bending, and the design of the weakening groove 501 makes the bending and straightening operations of the limiting tube 5 more convenient; the setting of the oblique groove 101 ensures that the limiting tube 5 can switch freely between the two states, and also facilitates the smooth rebound of the limiting tube 5 after being straightened, thereby ensuring the all-round protection of the emergency material box during transportation.

[0034] The working principle of the technical solution provided by the present invention is as follows: When in use, first place the emergency material box between the clamping pieces 2 in the loading area manually. The arc groove 3 facilitates the loader's hands to separate from the box. After the emergency material box is placed, start the transport robot to move towards the destination. Due to its own weight, the box will have a tendency to fall. At the same time, the clamping pieces 2 on both sides clamp and fix the emergency material box. The limiting pipe 5 is located on the side of the opening of the plate body 1. During transportation, the emergency material box is prevented from falling off. Since the bottom spacing between the two clamping pieces 2 is greater than the top spacing between the two clamping pieces 2, the box is clamped more tightly as it goes down, ensuring the stability of the box. In order to prevent bumps during transportation that may cause insufficient clamping force of the clamping pieces 2, a support The support blocks 4 are respectively arranged at the four corners of the inner wall of the plate body 1, and the support blocks 4 are used to provide secondary protection for the emergency material box to prevent the clamping sheet 2 from being squeezed and deformed. The support blocks 4 are used to support the four corners of the emergency material box to ensure that the emergency material box is safely delivered to the destination. The contact surface 701 of the support block 4 and the emergency material box is in a horizontal state, maximizing the contact surface 701 area with the box body, so as to more stably support the emergency material box. When the robot arrives at the destination according to the program, the controller 6 is automatically started. At this time, the lifting rod 601 slowly descends until the contact surface 701 contacts the ground, and the lifting rod 601 stops descending. During the process of the lifting rod 601 slowly descending, the lower pressure plate 602 drives the extension sheet 202 and the bottom of the clamping piece 2 are stretched downward. While the clamping piece 2 is stretched and deformed, the traction rod also pulls the support block 4 downward, causing the support block 4 to rotate downward. At the same time, the limiting tube 5 is also straightened upward under the action of the lifting rod 601 to release the limit on the emergency material box. At this time, the clamping force of the clamping piece 2 on the emergency material box is slowly reduced, and the supporting force of the support block 4 on the emergency material box is also slowly reduced synchronously. The emergency material box slowly falls until it falls to the ground. Due to the deadweight of each structure, the lower pressure plate 602 continues to press down on the inner airbag 702. The inner airbag 702 is flattened until the bottom of the lifting rod 601 contacts the bottom of the inner wall of the inner airbag 702. At this time, the trigger The rising function of the controller 6 is activated, and at the same time the transport robot starts the fast forward mode. The emergency material box is separated from the transport robot to realize automatic unloading. Since the inner airbag 702 and the outer airbag 7 are connected to each other through the connecting hole 703, the air in the inner airbag 702 is squeezed and transferred to the inside of the outer airbag 7, thereby increasing the contact surface 701 and the contact surface 701 area between the ground, thereby improving the overall stability of the transport robot, thereby replacing manpower to realize automatic unloading of the emergency material box. Compared with manual unloading, such a setting has higher efficiency in automatic unloading, saves manpower and material resources, improves the transportation efficiency of emergency materials, maximizes time benefits, and improves the rapid delivery capability of emergency materials.
