Description

Technical Field

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

[0002] Emergency materials refer to the material guarantees necessary for the entire process of emergency response to sudden public events such as severe natural disasters, accident disasters, public health events, and social security events. These materials need to be carried by rescue personnel during transportation, and long-term carrying will cause damage to the bodies of rescue personnel and affect the subsequent rescue efficiency.

[0003] With the continuous development of robot technology, in order to solve the above problems, robots with automatic loading and unloading have emerged in the current market. Most of the robots that can achieve automatic unloading at present are relatively large in size and cannot provide stronger mobility and flexibility. Moreover, the environment in the disaster-stricken area is complex, and the requirements for the delivery ability of emergency materials are high. The transportation and distribution of emergency materials need to be fast and efficient to ensure that necessary support can be provided to the disaster-stricken people in the shortest time. It is necessary for the transportation robot to be able to quickly reach the disaster-stricken area, timely provide necessary material support to the disaster-stricken people, and improve the delivery ability of emergency materials. Therefore, based on the above problems, the present invention provides an emergency material transportation robot to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an emergency material transportation robot. 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. The clamping component can not only clamp and fix the emergency material box, but also further clamp and support the emergency material box when the emergency material box moves downward due to bumps during the forward movement of the robot, so as to ensure that the emergency materials can be stable throughout the transportation process. The lifting component can not only buffer and stabilize the robot after it stops, but also pull the clamping component during the descending process, so as to realize the automatic unloading of the emergency material box instead of manual labor. Through the above settings, the problems that most of the robots that can achieve automatic unloading at present are relatively large in size, cannot provide stronger mobility and flexibility, cannot timely provide necessary material support to the disaster-stricken people, and have low delivery ability of emergency materials can be solved.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] An emergency material transportation robot, including a plate body, wherein clamping components are symmetrically installed on both sides of the inner wall of the plate body, the clamping components are used for fixing the emergency material box, and the clamping components are connected to the plate body; a lifting component, the lifting component is used for facilitating automatic unloading, and the lifting component is connected to the plate body.

[0007] Optionally, the clamping assembly includes clamping pieces fixedly connected to both sides of the inner wall of the plate body. The clamping pieces are linearly arrayed with hollow slots. A support block is rotatably installed on the inner wall of the plate body, and the support block corresponds to the positions of the hollow slots at both ends. A pull rod is rotatably connected to the bottom of the support block, and the bottom of the pull rod is fixedly connected to the bottom of the hollow slot. Extension pieces are fixedly connected to both ends of the bottom of the clamping piece.

[0008] Optionally, the inner side of the clamping piece is a curved elastic structure, and both the top and bottom of the clamping piece have arcs bent inward.

[0009] Optionally, the position of the support block close to the plate body has an arc bent upward, and the position of the support block close to the hollow slot is in a horizontal state.

[0010] Optionally, the clamping piece, the extension piece and the pull rod are of an integral manufacturing structure. Grooves are opened on both the plate body and the side of the clamping piece close to the plate body, and the grooves correspond to the positions of the support blocks.

[0011] Optionally, the plate body is a U-shaped structure surrounded by three sides. An arc-shaped groove is opened at the center of the plate body, and inclined slots are opened at the tops of both ends of the plate body.

[0012] Optionally, a limiting tube is slidably inserted into the bottom of the inner wall of the inclined slot. Weakening slots are evenly distributed at the bent part of the limiting tube, and the center of the limiting tube has an arc bent toward the inside of the plate body.

[0013] Optionally, the lifting assembly includes a controller fixedly connected inside the plate body. A lifting rod is slidably connected inside the controller. A lower pressing plate is fixedly connected to the bottom of the lifting rod. An inner airbag is fixedly connected to the bottom of the lower pressing plate. An outer airbag is sleeved outside the inner airbag. A communication hole is opened on one side of the inner airbag. The internal cavities of the inner airbag and the outer airbag are communicated through the communication hole. A contact surface is fixedly connected to the bottom of the outer airbag, and arc-shaped anti-slip grooves are evenly distributed on the contact surface.

[0014] Optionally, the inner airbag, the outer airbag and the contact surface are of an integral manufacturing structure. The outer contour of the lower pressing plate coincides with the inner wall contour of the outer airbag, and the bottom of the lifting rod extends into the inner airbag.

[0015] Optionally, the top of the lifting rod is fixedly connected to the bottom of the limiting tube, and the bottom of the extension piece is fixedly connected to the top of the lower pressing plate.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] 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.

[0018] 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.

[0019] 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.

[0020] By setting up the lifting rod, the lower pressing plate, the outer airbag and the inner airbag, during the process of the lifting rod descending, the lower pressing plate squeezes the inner airbag, causing the air inside the inner airbag to be squeezed into the cavity of the outer airbag. The outer contour of the outer airbag is enlarged, 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, prompting the lifting rod to rebound and rise to the initial state. With the cooperation of the structural characteristics of the inner airbag and the outer airbag, not only can the contact area with the ground be increased to make the robot stable during unloading, but also the pressure is conducted to the lifting rod through the deformation of the inner airbag to achieve automatic recovery after unloading, facilitating the next transportation work. It is not only simple and ingenious in structure, but also convenient, labor-saving and practical in operation.

[0021] By setting up the limiting tube and the inclined groove, the limiting tube has two states: before the lifting rod descends, the limiting tube is located on the side of the opening of the plate body, which can prevent the emergency supply box from slipping off the tail of the transportation robot. After the lifting rod descends, while the lifting rod slides downward, both ends of the limiting tube move downward. Weakening grooves are evenly distributed at the bending part of the limiting tube, which can reduce the resilience after the limiting tube is bent, making it easier for the limiting tube to be straightened after being bent. The design of the weakening grooves makes the bending and straightening operations of the limiting tube more convenient; the setting of the inclined groove ensures the free switching between the two states of the limiting tube and also facilitates the smooth rebound of the limiting tube after being straightened, ensuring the all-round protection of the emergency supply box during transportation.

[0039] As Figures 1 to 8 shown, an embodiment of the present invention provides an emergency material transportation robot, including a plate body 1. Clamping components are symmetrically installed on both sides of the inner wall of the plate body 1. The clamping components are used to fix the emergency material box, and the clamping components are connected to the plate body 1; a lifting component, the lifting component is used to facilitate automatic unloading, the lifting component is connected to the plate body 1, the plate body 1 is a U-shaped structure surrounded by three sides, an arc-shaped groove 3 is opened at the center of the plate body 1, and inclined grooves 101 are opened at the tops of both ends of the plate body 1 (as Figures 1 to 3As shown in the figure, the width dimension of the emergency supply box matches the distance between the tops of the two clamping pieces 2, the length dimension of the emergency supply box matches the inner wall length dimension of the plate body 1, the height dimension of the emergency supply box is the same as the top height of the plate body 1, and the dimensions of the emergency supply box are unified, which is convenient for better adapting to the transport robot, ensuring the smooth operation of the transport robot. With the arrangement of the plate body 1 with three-sided enclosure and one-sided opening, it can ensure clamping of the emergency supply box and also facilitate automatic unloading from the opening. The arc-shaped groove 3 is opened at the top center of the plate body 1. The arc-shaped groove 3 is opened to facilitate placing the emergency supply box into the plate body 1 by hand without pinching the hand, leaving a position for holding the emergency supply box. The inclined groove 101 facilitates the state switching of adjusting the limiting tube 5. During transportation, the limiting tube 5 is located on the side of the opening of the plate body 1 to prevent the emergency supply box from falling off. When starting automatic unloading, the limiting tube 5 is driven to be straightened, and the height of the limiting tube 5 exceeds the top of the emergency supply box, facilitating the smooth descent of the emergency supply box. By setting the clamping component and the 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 supply box, but also further clamp and support the emergency supply box when the emergency supply box moves downward due to bumps during the forward movement of the robot, thus ensuring the stability of the emergency supplies 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 process, thus realizing automatic unloading of the emergency supply box instead of manual labor. Such an arrangement, compared with manual unloading, has higher automatic unloading efficiency, saves manpower and material resources, improves the transportation efficiency of emergency supplies, maximizes the time benefit, and improves the rapid delivery ability of emergency supplies.

[0040] As an implementation manner in this embodiment, as Figures 1 to 5 shown, the clamping component includes clamping pieces 2 fixedly connected to both sides of the inner wall of the plate body 1. The clamping pieces 2 are linearly and arrayedly provided with hollow slots 201. A support block 4 is rotatably installed on the inner wall of the plate body 1. The support block 4 corresponds to the positions of the hollow slots 201 at both ends. A pull rod 401 is rotatably connected to the bottom of the support block 4. The bottom of the pull rod 401 is fixedly connected to the bottom of the hollow slot 201. Extension pieces 202 are fixedly connected to both ends of the bottom of the clamping pieces 2. The inner side of the clamping pieces 2 is a curved surface elastic structure. The top and bottom of the clamping pieces 2 both have an inward-bending arc. The clamping pieces 2, the extension pieces 202 and the pull rod 401 are integrally manufactured structures. 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 flat structure and is fixedly connected to the inside of the plate body 1. The other side of the clamping piece 2 is a wavy curved surface structure from top to bottom, and the arc-shaped curved surface at the bottom is more convex than that at the top (as Figure 5 shown), so that the bottom distance between the two clamping pieces 2 is greater than the top distance between the two clamping pieces 2 (as Figure 2As shown in the figure, the inner wall size of the hollow groove 201 is larger than the outer wall contour of the support block 4, and the entire rotation process of the support block 4 does not contact the inner wall of the hollow groove 201, ensuring that the support block 4 is not restricted by the hollow groove 201. The extension pieces 202 at both bottom ends of the clamping piece 2 are curved structures and extend to the top of the lower pressing plate 602 (as Figure 5 shown). The clamping piece 2, the extension piece 202 and the traction rod 401 are integrally manufactured structures. The integral structure manufacturing can not only reduce the production cost, make the connection between each two planes more reliable, and enable the overall structure to have higher strength, but also the construction process of the integral structure is simple and 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 uniformly distributed hollow grooves 201 are opened on the inner side. Manually place the emergency supply box between the clamping pieces 2, and utilize the self-weight of the emergency supply box and the elastic structure with an increasing radian from top to bottom of the clamping piece 2. During the process of the emergency supply box descending, the clamping piece 2 continuously clamps it to ensure the stability of the emergency supply box. The uniformly distributed hollow grooves 201 can not only increase the local flexibility of the plate body 1, enabling it to better adapt to deformation when stressed, but also the uniformly distributed hollow grooves 201 can reduce the material usage amount, thereby reducing the overall weight of the structure, improving the material utilization rate, reducing costs, and improving the practicability of the device.

[0041] In this embodiment, as Figure 5 and Figure 8 shown, the position of the support block 4 close to the plate body 1 has an upwardly curved radian, the position of the support block 4 close to the hollow groove 201 is in a horizontal state, grooves are opened on both the plate body 1 and the side of the clamping piece 2 close to the plate body 1, and the positions of the grooves correspond to those of the support block 4. One end of the support block 4 is rotationally connected to the inner wall of the groove through an aluminum-magnesium integrated return spring shaft, and the other end of the support block 4 is rotationally connected to the traction rod 401 through a rotating shaft. When a downward traction force is applied to the support block 4 through the traction rod, the support block 4 rotates downward around the aluminum-magnesium integrated return spring shaft. Once the downward traction force disappears, the support block 4 is reset by using the reset mechanism inside the aluminum-magnesium integrated return spring shaft (as Figure 8 shown). The internal structure and working principle of the aluminum-magnesium integrated return spring shaft are all publicly known in the prior art and will not be elaborated here. The contact surface 701 between the support block 4 and the emergency supply box is in a horizontal state (as Figure 5As shown in the figure, the contact area 701 with the box body is maximized to facilitate more stable support for the emergency supply box. By setting the support blocks 4 and the pull rods 401 in cooperation, the support blocks 4 are respectively arranged at the four corners of the inner wall of the plate body 1. The support blocks 4 are used to provide secondary protection for the emergency supply box to prevent the clamping pieces 2 from being squeezed and deformed. The support blocks 4 are used to support the four corners of the emergency supply box to ensure the safe delivery of the emergency supply box to the destination. The pull rods 401 can drive the support blocks 4 to rotate, facilitating automatic unloading after the robot reaches the destination. The pull rods 401 are lowered to rotate the support blocks 4 to release the limit on the emergency supply box, ensuring that the emergency supply box is smoothly transported to the destination. In addition, the clamping pieces 2, the extension pieces 202 and the pull rods 401 are integrally manufactured structures. Such a setting makes the processing technology of the three simpler in the production and manufacturing process, easier to be produced and manufactured, and reduces the capital investment of the manufacturer.

[0042] As an implementation manner in this embodiment, as Figures 4 to 7As shown, the lifting assembly includes a controller 6 fixedly connected inside the plate body 1. A lifting rod 601 is slidably connected inside the controller 6. A lower pressing plate 602 is fixedly connected to the bottom of the lifting rod 601. An inner airbag 702 is fixedly connected to the bottom of the lower pressing plate 602. An outer airbag 7 is sleeved outside the inner airbag 702. A communication hole 703 is formed on one side of the inner airbag 702. The inner cavities of the inner airbag 702 and the outer airbag 7 are communicated through the communication hole 703. A contact surface 701 is fixedly connected to the bottom of the outer airbag 7. Arc-shaped anti-slip grooves are evenly distributed on the contact surface 701. The inner airbag 702, the outer airbag 7 and the contact surface 701 are of an integrated manufacturing structure. The outer contour of the lower pressing plate 602 coincides with the inner wall contour of the outer airbag 7. The bottom of the lifting rod 601 extends into 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 pressing plate 602 drives the bottom of the extension piece 202 and the clamping piece 2 to be 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 limit tube 5 is also straightened upward under the action of the lifting rod 601, releasing the limit on the emergency supply box. At this time, the clamping force of the clamping piece 2 on the emergency supply box slowly decreases, and the supporting force of the support block 4 on the emergency supply box also slowly decreases synchronously. The emergency supply box slowly descends until it reaches the ground. Due to the self-weight of each structure, the lower pressing plate 602 continuously presses the inner airbag 702. The inner airbag 702 is flattened until the bottom of the lifting rod 601 touches the inner wall bottom 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 supply box is separated from the transport robot, realizing automatic unloading. Since the inner airbag 702 and the outer airbag 7 are communicated through the communication hole 703, the air in the inner airbag 702 is transferred to the inside of the outer airbag 7 when the inner airbag 702 is squeezed, increasing the contact area of the contact surface 701 with the ground and improving the overall stability of the transport robot. By setting the lifting rod 601, the lower pressing plate 602, the outer airbag 7 and the inner airbag 702, during the descent of the lifting rod 601, the lower pressing 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. The outer contour of the outer airbag 7 is enlarged, increasing the contact area of the contact surface 701 with the ground. The inner airbag 702 is flattened until it touches the bottom of the lifting rod 601, prompting the lifting rod 601 to rebound and rise to the initial state. With the cooperation of the self-structural characteristics of the inner airbag 702 and the outer airbag 7, not only can the contact area with the ground be increased, making the robot stable during unloading, but also the deformation of the inner airbag 702 is used to conduct pressure to the lifting rod 601, realizing automatic recovery after unloading and facilitating the next transportation work. It is not only simple and ingenious in structure, but also convenient to operate in practice.

[0043] In this embodiment, as Figures 4 to 6 shown, the top of the lifting rod 601 is fixedly connected to the bottom of the limiting tube 5. The bottom of the inner wall of the inclined slot 101 is slidably inserted with the limiting tube 5. Uniformly distributed weakening slots 501 are formed at the bent portion of the limiting tube 5. The center of the limiting tube 5 has a curvature that bends towards 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 as to apply a downward pulling force to the limiting tube 5 while the lifting rod 601 descends. Thus, it is convenient to straighten the limiting tube 5 under the action of the weakening slots 501. The inside of the limiting tube 5 is hollow, which can reduce the self-weight of the material and save costs. The center of the limiting tube 5 is provided with a curvature that bends towards the emergency supply box. In order to increase the buffering of the box body and keep the box body stable, by setting the limiting tube 5 and the inclined slot 101, the limiting tube 5 has two states: before the lifting rod 601 descends, the limiting tube 5 is located on the side of the opening of the plate body 1, which can prevent the emergency supply box from slipping off the tail of the transport robot. After the lifting rod 601 descends, while the lifting rod 601 slides downward, both ends of the limiting tube 5 move downward. Uniformly distributed weakening slots 501 are formed at the bent portion of the limiting tube 5, which can reduce the resilience after the limiting tube 5 is bent, so that the limiting tube 5 can be more easily straightened after being bent. The design of the weakening slots 501 makes the bending and straightening operations of the limiting tube 5 more convenient; the setting of the inclined slot 101 ensures the free switching between the two states of the limiting tube 5 and also facilitates the smooth rebound of the limiting tube 5 after being straightened, ensuring the all-round protection of the emergency supply box during transportation.

[0044] The working principle of the technical solution provided by the present invention is as follows:

[0045] During use, first place the emergency supply box manually in the loading area between the clamping pieces 2. The arc-shaped groove 3 facilitates the separation of the hands of the loader from the box body. After the emergency supply box is placed, start the transport robot to move forward to the destination. Due to its own weight, the box body has a tendency to descend. At the same time, the clamping pieces 2 on both sides clamp and fix the emergency supply box. The limiting tube 5 is located on the side of the opening of the plate body 1 and prevents the emergency supply box from falling off during transportation. Since the bottom spacing between the two clamping pieces 2 is greater than the top spacing between the two clamping pieces 2, the lower the box body, the tighter it is clamped, ensuring the stability of the box body. To prevent insufficient clamping force of the clamping pieces 2 due to jolts during transportation, the support blocks 4 are respectively arranged at the four corners of the inner wall of the plate body 1. The support blocks 4 are used to provide secondary protection for the emergency supply box to prevent the clamping pieces 2 from being squeezed and deformed, and the support blocks 4 are used to support the four corners of the emergency supply box to ensure the safe delivery of the emergency supply box to the destination. The contact surface 701 between the support block 4 and the emergency supply box is in a horizontal state, maximizing the contact area 701 with the box body and facilitating more stable support of the emergency supply box. When the robot reaches the destination according to the program, the controller 6 is automatically activated. 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 pressing 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, releasing the limit on the emergency supply box. At this time, the clamping force of the clamping piece 2 on the emergency supply box slowly decreases, and the supporting force of the support block 4 on the emergency supply box also slowly decreases synchronously. The emergency supply box slowly descends until it reaches the ground. Due to the self-weight of each structure, the lower pressing plate 602 continuously presses the inner airbag 702 downward, and the inner airbag 702 is flattened until the bottom of the lifting rod 601 touches the inner bottom 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 supply box is separated from the transport robot, realizing automatic unloading. Since the inner airbag 702 and the outer airbag 7 are connected through the communication hole 703 to make the internal cavities communicate, the air in the inner airbag 702 is transferred to the inside of the outer airbag 7 when the inner airbag 702 is squeezed, increasing the contact area 701 with the ground and improving the overall stability of the transport robot. Thus, it can replace manual labor to achieve automatic unloading of the emergency supply box. Such a setting has a higher efficiency of automatic unloading compared to manual unloading, saves manpower and material resources, improves the transportation efficiency of emergency supplies, maximizes the time benefit, and improves the rapid delivery ability of emergency supplies.

[0046] The present invention encompasses any alternatives, modifications, equivalent methods, and solutions that are within the spirit and scope of the present invention. To enable the public to have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention.
