Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of manipulators, and in particular, to a multifunctional manipulator for rescue and maintenance. Background Art

[0002] In modern society, various accidents and facility damages occur from time to time, and rescue and maintenance work faces huge challenges. Whether it is natural disasters such as earthquakes and floods that cause building collapse and infrastructure damage, or equipment failures in industrial accidents and vehicle damage in traffic accidents, efficient and reliable rescue and maintenance equipment is needed to assist in completing the task.

[0003] In existing rescue and maintenance scenarios, traditional manipulator equipment has many limitations. On the one hand, most manipulators have relatively simple functions and can only perform simple grabbing and carrying operations, which makes it difficult to meet the complex and changing rescue and maintenance needs. For example, at the rescue site of a collapsed building, it is not only necessary to grab trapped people and objects, but also possible to clear surrounding obstacles and temporarily support and reinforce the building structure, etc., and traditional manipulators cannot complete these diverse tasks.

[0004] On the other hand, existing manipulators are poor in adaptability and flexibility. In narrow spaces such as gaps between rubble, inside accident vehicles, or in high-altitude working environments, traditional manipulators have difficulty flexibly adjusting their positions to reach areas that are difficult for operators to reach, resulting in the inability to carry out rescue and repair work smoothly. Moreover, for objects of different shapes and sizes, traditional manipulators have limited grasping capabilities and cannot stably grasp various objects, affecting the efficiency and effectiveness of rescue and repair.

[0005] In addition, when grabbing and moving objects, the stability of surrounding objects is often difficult to ensure, which can easily cause the collapse of surrounding objects during the operation, posing a safety threat to rescue personnel and equipment and increasing the risk of rescue work.

[0006] To sum up, the existing rescue and maintenance manipulators have obvious deficiencies in terms of functional diversity, adaptability, flexibility and safety. There is an urgent need for a new type of multifunctional manipulator to solve these problems in order to meet the increasingly complex needs of rescue and maintenance work. Summary of the invention

[0007] In order to overcome the above-mentioned defects, the embodiments of the present disclosure provide a multifunctional manipulator for rescue and maintenance, which solves the technical problem in the related art that the manipulator is prone to collapse when grasping and moving objects, affecting the rescue efficiency and safety.

[0008] According to one aspect, at least one embodiment of the present disclosure provides a multifunctional manipulator for rescue and maintenance, which is used to be arranged on a vehicle body, comprising: A mechanical arm, used to be arranged on the vehicle body; A mounting frame, arranged at the end of the mechanical arm; A grabbing assembly, arranged on the mounting frame, and used for grabbing and moving objects; A support assembly is arranged on the mounting frame, the support assembly is located around the grabbing assembly, and the support assembly is used to support other objects around the object to be grabbed and moved.

[0009] For example, at least one embodiment of the present disclosure provides a multifunctional manipulator for rescue and maintenance, wherein the grasping assembly includes: A telescopic member, arranged on the mounting frame; A gripper is arranged on the telescopic member, and the gripper is used for gripping and moving objects.

[0010] For example, at least one embodiment of the present disclosure provides a multifunctional manipulator for rescue and maintenance, wherein the gripper comprises: The clamping arms are hingedly arranged on the telescopic member, and at least two clamping arms are arranged opposite to each other. After the at least two clamping arms are swung, they move closer to or farther away from each other. The clamping arms are used to clamp or cancel the clamping of objects.

[0011] For example, at least one embodiment of the present disclosure provides a multifunctional manipulator for rescue and maintenance, further comprising: The groove digging component is movably arranged on the clamping arm, and the groove digging component is used for digging grooves on the surface of the object.

[0012] For example, at least one embodiment of the present disclosure provides a multifunctional manipulator for rescue and maintenance, wherein the support assembly includes: A support rod is hinged / movably arranged on the mounting frame, and the support rod has a support segment. The support rod has a plurality of support rods, and the plurality of support rods are distributed around the grabbing assembly. After the plurality of support rods are swung / moved, the plurality of support segments approach or move away from each other.

[0013] For example, at least one embodiment of the present disclosure provides a multifunctional manipulator for rescue and maintenance. One end of the support rod is provided with a pressing surface, the pressing surface is used to press the object to be grasped and moved, and the pressing surface is provided with an anti-slip protrusion.

[0014] For example, at least one embodiment of the present disclosure provides a multifunctional manipulator for rescue and maintenance. The support rods are provided with at least three; The support assembly also includes: There are a plurality of blocking members between each of the two adjacent support rods, and the blocking members are used to block objects that are about to fall through the gap between the adjacent support rods.

[0015] For example, at least one embodiment of the present disclosure provides a multifunctional manipulator for rescue and maintenance. The blocking member is a telescopic rod, and two ends of the telescopic rod are respectively hinged on two adjacent support rods.

[0016] For example, at least one embodiment of the present disclosure provides a multifunctional manipulator for rescue and maintenance. The blocking member is a mesh body, and the mesh body is arranged between two adjacent support rods.

[0017] For example, at least one embodiment of the present disclosure provides a multifunctional manipulator for rescue and maintenance. One side of the net body is fixedly arranged on one of the support rods, and the other side is movably arranged on another adjacent support rod. When two adjacent support sections approach or move away from each other, the net body shortens or lengthens.

[0018] The beneficial effects of the embodiments of the present disclosure are: In the present disclosure, the overall structural design of the multifunctional manipulator lays the foundation for its stable installation on the vehicle body by organically combining the manipulator arm, the mounting frame, the grabbing assembly and the supporting assembly. The design of the manipulator arm (the existing multi-degree-of-freedom manipulator arm) can rotate and retract at multiple angles in the horizontal and vertical directions, and can flexibly adjust its position in complex rescue and maintenance sites, such as narrow ruins spaces, around accident vehicles, etc., to reach areas that are difficult for operators to reach. The existence of the grabbing assembly enables it to accurately grab and move various objects, whether small parts or larger rescue equipment, and can easily deal with them. The supporting assembly surrounds the grabbing assembly and can support the surrounding objects when grabbing and moving objects. For example, in the rescue of collapsed buildings, it can avoid the collapse of surrounding walls, debris, etc. due to the vibration of the grabbing action when grabbing trapped people or important items, which greatly improves the safety and stability of the rescue operation and ensures that the rescue work is carried out in an orderly manner.

[0026] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0027] like Figure 1~Figure 4 As shown, it shows a multifunctional manipulator for rescue and maintenance in one embodiment of the present disclosure, which is used to be set on a vehicle body 1, including: a manipulator arm 2, a mounting frame 3, a grabbing assembly 4 and a supporting assembly 5, the manipulator arm 2 is used to be set on the vehicle body 1; the mounting frame 3 is set at the end of the manipulator arm 2; the grabbing assembly 4 is set on the mounting frame 3, and the grabbing assembly 4 is used to grab and move objects; the supporting assembly 5 is set on the mounting frame 3, and the supporting assembly 5 is located around the grabbing assembly 4, and the supporting assembly 5 is used to support other objects around the object to be grabbed and moved.

[0028] The overall structural design of the multifunctional manipulator lays the foundation for its stable installation on the vehicle body 1 by organically combining the manipulator arm 2, the mounting frame 3, the grabbing assembly 4 and the supporting assembly 5. The design of the manipulator arm 2 (with multiple degrees of freedom) can rotate and retract at multiple angles in the horizontal and vertical directions, and can flexibly adjust its position in complex rescue and maintenance sites, such as narrow ruins spaces, around accident vehicles, etc., to reach areas that are difficult for operators to reach. The existence of the grabbing assembly 4 enables it to accurately grab and move various objects, whether small parts or larger rescue equipment, and can easily handle them. The supporting assembly 5 surrounds the grabbing assembly 4 and can support the surrounding objects when grabbing and moving objects. For example, in the rescue of collapsed buildings, it can avoid the collapse of surrounding walls, debris, etc. due to the vibration of the grabbing action when grabbing trapped people or important items, which greatly improves the safety and stability of the rescue operation and ensures that the rescue work is carried out in an orderly manner.

[0029] In some examples, the grabbing assembly 4 includes a telescopic member 41 and a gripper 42 . The telescopic member 41 is disposed on the mounting frame 3 ; the gripper 42 is disposed on the telescopic member 41 , and the gripper 42 is used to grab and move objects.

[0030] For example, Figure 2As shown, in actual rescue and maintenance scenarios, facing objects in different positions, the telescopic member 41 can be freely extended and retracted within a certain range according to the distance between the object and the manipulator. For example, when repairing equipment at a high altitude, the telescopic member 41 can be extended to allow the gripper 42 to reach the target position; if the object is located in a narrow gap, the telescopic member 41 can be retracted to allow the gripper 42 to smoothly enter and grab the object. This function of flexibly adjusting the position of the gripper 42 according to actual conditions greatly enhances the applicability of the gripping component 4, and can efficiently complete the gripping task whether it is in a small indoor space or in an open outdoor space for rescue and maintenance work.

[0031] In addition, the support component 5 can cooperate with the grabbing component 4, that is, the support component 5 supports the objects around the object to be grabbed (to prevent the grabbing component 4 from collapsing during the grabbing operation), and the telescopic part 41 is extended and retracted to drive the grabber 42 to realize the grabbing operation, thereby grabbing the object to be moved and realizing a quick rescue operation.

[0032] In some examples, the gripper 42 includes a clamping arm 43, which is hinged on the telescopic member 41. At least two clamping arms 43 are relatively arranged, and at least two clamping arms 43 move closer to or away from each other after swinging. The clamping arms 43 are used to clamp or cancel clamping objects.

[0033] For example, Figure 2 As shown, the clamping arms 43 are hinged on the telescopic member 41, and at least two are arranged opposite to each other. This design improves the gripping ability of the manipulator. When facing objects of different shapes and sizes, the clamping arms 43 can clamp and cancel the gripping of the object by swinging. Multiple clamping arms 43 can be adaptively adjusted according to the contour of the object, clamping the object from different angles to ensure the stability of the gripping, greatly improving the gripping ability and adaptability of the manipulator to various objects, and broadening its application scope in the field of rescue and maintenance.

[0034] In some examples, a slotting assembly 44 is also included, and the slotting assembly 44 is moved (refer to Figure 3 As shown, the grooving assembly 44 can be slidably set on the clamping arm 43 by a slider. When grooving is required, the slider drives the grooving assembly 44 to move to the front end of the clamping arm 43 to start grooving. When grooving is not required, the slider drives the grooving assembly 44 to be retracted to a position away from the front end of the clamping arm 43. On the clamping arm 43, the grooving assembly 44 is used to dig grooves on the surface of an object.

[0035] For example, Figure 3As shown, the configuration of the grooving assembly 44 brings more possibilities for rescue and maintenance work (it is a core feature that improves the adaptability and extensiveness of grabbing). In actual operation, on the one hand, when it is necessary to fix or connect an object, the grooving assembly 44 can dig a groove on the surface of the object. For example, when repairing a damaged bridge, in order to better combine the reinforcement material with the bridge structure, the grooving assembly 44 can be used to dig a suitable groove on the surface of the bridge, and then the reinforcement material can be embedded in it to increase stability. This function effectively expands the application scenarios of the manipulator, so that it can not only perform simple grabbing and moving operations, but also complete some complex work of processing the surface of the object, meeting the diverse needs of rescue and maintenance work; on the other hand, when the object to be grabbed and moved is large or irregular in shape, and the gripper 42 is difficult to grasp stably, the grooving assembly 44 can be used to dig a groove at a suitable position on the surface of the object, so as to facilitate the gripper 42 to grab the grooved part of the object, and the object can be grabbed and moved, which is very convenient, greatly increasing the extensiveness of the object grabbed by the gripping assembly 4, and the grabbing is also more stable, which is more conducive to rescue.

[0036] In some examples, the support assembly 5 includes a support rod 51, which is hinged / movably disposed on the mounting frame 3, and the support rod 51 has a support segment 52. The support rod 51 has a plurality of support rods 51, and the plurality of support rods 51 are distributed around the grasping assembly 4. After the plurality of support rods 51 swing / move, the plurality of support segments 52 approach or move away from each other.

[0037] For example, Figure 2 As shown, multiple support rods are distributed around the grabbing assembly 4, and the support sections 52 can be moved closer or farther away from each other by swinging or moving. This design is very practical. At the rescue site, the environment around the object being grabbed is often complex and changeable, and the support rod 51 can flexibly adjust the support range and strength according to the actual situation of the surrounding objects. For example, in the rescue of ruins after an earthquake, when it is necessary to grab buried objects, the support rod 51 can be adjusted to a suitable position to support the surrounding ruins walls and debris to prevent these objects from collapsing during the grabbing process, creating a safe environment for the grabbing work, ensuring the smooth progress of the grabbing work, and improving the rescue efficiency.

[0038] In some examples, one end of the support rod 51 has a pressing surface 53 , and the pressing surface 53 is used to press the object to be moved, and the pressing surface 53 has an anti-slip protrusion 54 .

[0039] For example, Figure 3As shown, the pressing surface 53 at one end of the support rod 51 is specifically used to press the object to be grasped and moved (large or irregularly shaped objects are difficult to grasp and move), and the design of the anti-slip protrusion further enhances the stability of the pressing. At the same time, the groove component 44 makes grooves at appropriate positions on the surface of the object, and the grooved object is easier to be stably grasped by the gripper 42. The pressing surface 53 cooperates with the groove component 44 to quickly make grooves on the surface of the object, and facilitate the subsequent grasping and moving operations of the object, greatly improving efficiency.

[0040] In some examples, at least three support rods 51 are provided; the support assembly 5 further includes a stopper 55 , and a plurality of stoppers 55 are provided between each two adjacent support rods 51 , and the stoppers 55 are used to block objects that are about to fall through the gap between the adjacent support rods 51 .

[0041] For example, Figure 2 As shown, at least three support rods 51 are provided to form a stable support structure, and a space for the grabbing assembly 4 to operate is formed between at least three support rods 51, which can provide more reliable support for surrounding objects. At the same time, the setting of the blocking member 55 effectively solves the problem of objects falling from the gaps between adjacent support rods. At the rescue and maintenance site, especially when handling some fragmentary items or small components, the blocking member can prevent these items from falling around the grabbing assembly 4, avoiding the normal progress of the rescue work being affected by the falling of items, and ensuring the smooth operation of the grabbing assembly 4.

[0042] In some examples, the stopper 55 is a telescopic rod, and both ends of the telescopic rod are respectively hinged to two adjacent support rods 51 .

[0043] For example, Figure 2 As shown, when the block 55 is a telescopic rod and both ends are hinged on adjacent support rods, it has excellent adaptive ability. As the support rod swings or moves, the telescopic rod can automatically adjust its length and always remain in a suitable position to prevent objects from falling. In actual applications, when the support assembly 5 is adjusted according to different rescue scenarios, the telescopic rod block can adapt to such changes in time to ensure that a good blocking effect can be exerted under various support conditions. For example, when the distance between the objects to be supported is different, the angle and position of the support rod 51 will continue to change, and the telescopic rod block 55 can be adjusted accordingly to effectively prevent the object from sliding off, ensuring the smooth operation of the grabbing assembly 4 in the space surrounded by each support rod 51.

[0044] In some examples, the blocking member 55 is a mesh, and the mesh is disposed between two adjacent support rods 51 .

[0045] For example, Figure 4As shown, the use of a mesh as a blocker disposed between adjacent support rods has unique advantages. The structure of the mesh can effectively prevent smaller objects from falling, and its relatively soft characteristics allow it to adapt to the blocking needs of objects of different shapes to a certain extent. When dealing with some objects with irregular shapes and containing many small parts, the mesh can be deformed to a certain extent according to the contour of the object to better play a blocking role. For example, if there are many scattered objects around the object to be grasped and moved, when the object is grasped and moved, the mesh can effectively prevent these small objects from falling from the gap between the support rods 51, ensuring the stability of the object grasping and moving process, which is more conducive to rescue operations.

[0046] In some examples, one side of the mesh is fixedly disposed on one of the support rods 51, and the other side is movably disposed on another adjacent support rod 51, and when two adjacent support segments 52 move closer or farther away, the mesh shortens or lengthens.

[0047] The design of the mesh body with one side fixed and the other side movable allows it to automatically shorten or lengthen as the adjacent support segments approach or move away. In actual operation, when the support assembly 5 is adjusted according to the surrounding environment of the object being grasped and moved, the mesh body can adapt to this change in real time and always maintain an effective blocking state. For example, when grasping and moving objects in different positions, the distances of the objects around the object that need to be supported may be different, then the support range of the support assembly 5 will change adaptively, and the mesh body can also adjust its length accordingly, ensuring that the object can be effectively blocked from falling in any supporting state, thereby improving the applicability and practicality of the mesh body.

[0048] Reference Figure 4 As shown, a reel 56 is rotatably arranged inside the support rod 51, an opening 58 is opened on the side wall of the support rod 51, and one side of the mesh 57 is movably arranged to pass through the opening and be wound on the reel. By controlling the rotation of the reel (the mesh is wound on the reel), the length of the mesh between two adjacent support rods 51 can be controlled, thereby adapting the process in which the mesh follows the change in the distance between the adjacent support rods 51.

[0049] In some examples, trenching assembly 44 is a drill or a cutter.

[0050] The grooving component 44 can be selected as a drilling machine or a cutting machine. This design greatly improves the practicality and pertinence of the grooving component. In rescue and maintenance work, different working scenes and object materials require different grooving methods. For harder metal materials, a cutting machine can be selected for grooving; while for brittle materials such as concrete, a drilling machine can be used for grooving operations. This function of flexibly selecting the grooving method according to actual needs enables the manipulator to meet the grooving requirements in various complex working scenes, and improves its comprehensive application capabilities in the field of rescue and maintenance.

[0051] In some examples, the telescopic member 41 is a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0052] The telescopic member 41 adopts an air cylinder, an oil cylinder or an electric cylinder, which can drive the gripper 42 to telescope and grasp and move the object.

[0053] A method for using a manipulator in another embodiment of the present disclosure, When the support assembly 5 plays a supporting role, the following steps are included: S1: The vehicle body 1 and the robot arm 2 move to the vicinity of the object to be grasped; S2: The support component 5 moves to the surroundings of the object to be grasped and supports it, and the grasping component 4 grasps and moves the object.

[0054] When grasping a key object, if there are other things around the object that may affect the grasping of the object, or if the surroundings of the object are prone to collapse, first support the surroundings of the object through the support component 5, which can not only reduce the difficulty of grasping the corresponding object, but also improve the safety of the operation.

[0055] When the support assembly 5 performs a pressing action, the following steps are included: A1: Vehicle 1 and robot arm 2 move to the vicinity of the object to be grasped; A2: The pressing surface 53 of the supporting component 5 presses the object to be moved, and the groove digging component 44 digs a groove on the surface of the object; A3: The gripper 42 grabs the groove of the object and moves the object.

[0056] When facing an object that is large or difficult to grasp, the groove component 44 is used to first dig a groove on the surface of the object to facilitate the gripper 42 to grasp the object. This not only makes it possible to grasp objects that are inconvenient to grasp, but also improves the stability of grasping and reduces the possibility of secondary injuries.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure rather than to limit it. Although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present disclosure, which should be included in the scope of the claims of the present disclosure.
