Description

Technical Field

[0001] The present invention relates to the field of emergency rescue engineering, and in particular to an emergency rescue device and a multifunctional emergency rescue vehicle. Background Art

[0002] At present, in the field of emergency rescue, the existing emergency rescue equipment is mainly conventional engineering machinery, most of which have single functions and can only complete a single type of emergency rescue operations. They also have poor mobility and low passability, making it difficult to quickly reach the front line of emergency rescue. Emergency rescue departments are in urgent need of powerful, flexible and maneuverable emergency rescue equipment.

[0003] The multifunctional emergency rescue vehicle is a highly maneuverable multifunctional rescue vehicle that integrates high-speed off-road, excavation, crushing, grabbing, shearing, cutting and other functions. It has broad application prospects in the field of emergency rescue. However, the current multifunctional emergency rescue vehicles generally adopt the solution of on-board hoisting: a on-board crane is configured on the vehicle. Before the rescue, the on-board crane is operated to hoist all the operating tools down and arrange them in a suitable position. Then, when the operating tools need to be replaced, the relative position of the vehicle and the operating tools is determined in advance before the replacement operation is carried out.

[0004] It can be seen that the existing multifunctional emergency rescue vehicles have the problem of long time and low efficiency in the replacement of operating tools during the rescue preparation and rescue process. Moreover, the process of replacing the operating tools requires a certain operating site, which not only has high requirements for the emergency rescue site, but also affects the passability of other rescue vehicles and personnel.

[0045] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0046] like Figures 1-2 As shown, in one aspect of the present disclosure, there is provided an emergency rescue device, comprising:

[0047] Rotating platform 1;

[0048] At least two types of working machines 2, capable of performing at least two types of emergency rescue operations respectively;

[0049] The working arm 3 is variably arranged on the rotary platform 1 with a pitch angle, and comprises at least two telescopic arms;

[0050] A connector assembly 4, disposed on the working arm 3 and configured to selectively assemble one of at least two working tools 2; and

[0051] The driving assembly 5 is configured to drive the rotary motion of the rotary platform 1, the amplitude variation motion of the working arm 3 and the telescopic motion of the telescopic arm, so that the connecting head assembly 4 moves to a set position along a preset path and is assembled with the corresponding working machine 2.

[0052] Among them, at least two working tools 2 include at least two of hydraulic shears 251, breaker hammer 252, stone grabber 253, rock saw, cutter 254 and bucket 255, so as to respectively realize rescue operations such as excavation, demolition, cutting, grabbing, etc., or combine in a certain order of use to complete comprehensive emergency rescue operations.

[0053] The connector assembly 4 is provided on the working arm 3 and is used to connect with the working machine 2, so as to expand the working range of the working machine 2 by utilizing the slewing motion of the slewing platform 1, the amplitude variation motion of the working arm 3 and the telescopic motion of the telescopic arm, and the driving assembly 5 is used to drive the slewing platform 1, the working arm 3 and the telescopic arm. Since the connector assembly 4 and the working machine 2 have a unified connection form, the driving assembly 5 can be configured to make the connector assembly 4 move to a set position along a preset path and then be assembled with the corresponding working machine 2.

[0054] At least two types of work tools 2 can be arranged on the rotating platform 1, so that the connection process between the connecting head assembly 4 and the work tool 2 does not need to consider the influence of the rotation angle of the rotating platform 1, and the assembly with the work tool 2 can be achieved more quickly only by relying on the amplitude change and extension of the working arm 3 itself; of course, at least two types of work tools 2 can also be arranged outside the rotating platform 1 to reduce the load of the rotating platform 1, so that the rotation movement of the rotating platform 1 is more flexible and consumes less energy.

[0055] In a preferred embodiment, different work tools 2 are arranged according to their frequency of use. The work tools 2 with higher frequency of use are arranged on the rotary platform 1, while the work tools 2 with lower frequency of use are arranged outside the rotary platform 1, so as to take into account the rapid replacement of the work tools 2 with higher frequency of use and reduce the influence of the work tools 2 with lower frequency of use on the rotary motion of the rotary platform 1.

[0056] The drive assembly 5 may be hydraulically driven to allow the work tool 2 to have a larger workload during emergency and rescue operations, or may be electrically driven to allow the work tool 2 to have greater flexibility during emergency and rescue operations.

[0057] like Figure 2 As shown, in some embodiments, the connector assembly 4 includes a plug connector 41, and the work tool 2 includes a plug hole 21 corresponding to the plug connector 41. When the connector assembly 4 moves to a set position, the plug connector 41 can be plugged into the interior of the plug hole 21 to connect the connector assembly 4 to the work tool 2.

[0058] In order to achieve a locking connection between the connecting head assembly 4 and the working tool 2, in some embodiments, the connecting head assembly 4 includes at least one locking pin 42, and the working tool 2 includes at least one locking pin hole 22 corresponding to the at least one locking pin 42. When the plug connector 41 is plugged into the interior of the plug hole 21, at least one locking pin 42 can extend into at least one locking pin hole 22 to achieve a locking connection between the connecting head assembly 4 and the working tool 2.

[0059] Furthermore, at least one locking pin 42 is telescopically disposed on the first side wall 411 of the plug connector 41, and at least one locking pin hole 22 is correspondingly opened on the first inner wall 211 of the plug hole 21; wherein, the direction in which at least one locking pin 42 extends into at least one locking pin hole 22 is perpendicular to the direction in which the plug connector 41 is plugged into the plug hole 21.

[0060] like Figure 2 The number of locking pins 42 shown is two, and the number of corresponding locking pin holes 22 is also two, and the arrangement direction of the two locking pins 42 is not only perpendicular to the direction in which the locking pins 42 are inserted into the locking pin holes 22, but also perpendicular to the direction in which the plug connector 41 is inserted into the plug hole 21, thereby realizing the positioning connection between the connector assembly 4 and the work tool 2 in three orthogonal directions, preventing the work tool 2 from shaking or even falling off relative to the connector assembly 4 during emergency rescue operations.

[0061] In order to achieve a secure connection between the connecting head assembly 4 and the working tool 2, in some embodiments, the connecting head assembly 4 includes a connecting rod 23, and the working tool 2 includes a connecting groove 43 corresponding to the connecting rod 23. When the plug connector 41 is inserted into the interior of the plug hole 21, the connecting rod 23 can be embedded in the connecting groove 43 to achieve a secure connection between the connecting head assembly 4 and the working tool 2.

[0062] Furthermore, in some embodiments, the connecting groove 43 is arranged on the second side wall 412 of the plug connector 41, the connecting rod 23 is correspondingly arranged on the second inner wall 212 of the plug hole 21, and the second side wall 412 and the second inner wall 212 are respectively arranged relative to the first side wall 411 and the first inner wall 211.

[0063] like Figure 2 As shown, the connection plane where the locking pin hole 22 and the locking pin shaft 42 are located is arranged opposite to the connection plane where the connecting rod 23 and the connecting groove 43 are located, so that the connection relationship between the connecting head assembly 4 and the working tool 2 is clamped by the two relatively arranged connection planes, further improving the connection stability between the connecting head assembly 4 and the working tool 2.

[0064] In order to achieve the hydraulic drive connection of the work tool 2, in some embodiments, the connecting head assembly 4 includes a first assembly surface 44, and the work tool 2 includes a second assembly surface 24 corresponding to the first assembly surface 44. When the connecting head assembly 4 moves to the set position, the first assembly surface 44 and the second assembly surface 24 are fitted and connected to each other.

[0065] Furthermore, in some embodiments, a first hydraulic connector 441 is provided on the first assembly surface 44, and a second hydraulic connector 241 is provided on the second assembly surface 24. When the first assembly surface 44 is fitted and connected to the second assembly surface 24, the first hydraulic connector 441 and the second hydraulic connector 241 can achieve hydraulic conduction to realize the connection of the hydraulic pipeline between the connecting head assembly 4 and the working tool 2.

[0066] In order to perform pre-positioning during the process of cooperation between the first assembly surface 44 and the second assembly surface 24, in some embodiments, a positioning pin 442 is provided on the first assembly surface 44, and a positioning pin hole 242 is provided on the second assembly surface 24. During the process of the first assembly surface 44 being fitted and connected to the second assembly surface 24, the positioning pin 442 can cooperate with the positioning pin hole 242 to achieve positioning of the first assembly surface 44 and the second assembly surface 24.

[0067] In some embodiments, the positioning pin 442 is vertically disposed on the first assembly surface 44 , and the direction in which the positioning pin 442 extends into the positioning pin hole 242 is parallel to the direction in which the plug connector 41 is plugged into the plug hole 21 .

[0068] In another aspect of the present disclosure, a multifunctional emergency rescue vehicle is provided, comprising an emergency rescue device as described in any of the above embodiments.

[0069] In some embodiments, the multifunctional emergency rescue vehicle comprises:

[0070] Multi-terrain off-road chassis 6, used to improve the trafficability of emergency rescue vehicles;

[0071] A bulldozer 7 is escalably disposed at the front of the multi-terrain off-road chassis 6 and is configured to perform ground obstacle clearing operations at a low position; and

[0072] The frog-shaped legs 8 are extendably arranged on the multi-terrain off-road chassis 6, and are configured to be deployed outwardly and downwardly to support the rescue vehicle on the ground when the rescue device carries out rescue operations.

[0073] Among them, the multi-terrain off-road chassis 6 has high maneuverability and strong road adaptability, and can adapt to a variety of severe road conditions; the bulldozer 7 is arranged in a liftable manner at the front position of the multi-terrain off-road chassis 6, so that when it is in a low position, it can achieve ground obstacle clearance operations, and when it is in a high position, it improves the traffic capacity of the multi-terrain off-road chassis 6 and ensures the transfer transportation of the multi-functional emergency rescue vehicle; and the frog-shaped outriggers 8 can be unfolded and support the entire vehicle to stabilize it.

[0074] In some embodiments, the positions of at least two working tools 2 are fixed relative to the rescue vehicle, and the drive component 5 is further configured to: respond to the assembly instruction, take the position of the working tool 2 pointed to by the assembly instruction as the target coordinate point, and control the connecting head component 4 to move to the target coordinate point along a preset path.

[0075] Specifically, in some embodiments, the drive assembly 5 is further configured as:

[0076] In the program debugging mode, the position coordinate information and movement information of the path on which the connector assembly 4 is moved from the initial position to the target coordinate point by manual manipulation are recorded;

[0077] In the autonomous learning mode, the key coordinate points, repeated coordinate points and useless coordinate points in the position coordinate information are screened, and based on the position coordinate information, the optimized path of the connector assembly 4 moving from the initial position to the target coordinate point is calculated according to the screened key coordinate points, repeated coordinate points and useless coordinate points; and

[0078] In the storage mode, the optimized path is combined with the motion information at the key coordinate points and stored as a preset path.

[0079] In a preferred embodiment, the above-mentioned key coordinate points can be the position coordinate points where the motion information changes, that is, when the connector assembly 4 is at these key coordinate points, the changes in the three parameters of rotation angle, amplitude variation angle and telescopic length produce new change trends; the above-mentioned repeated coordinate points include two coordinate points whose position coordinate information is completely repeated between two adjacent key coordinate points; and the above-mentioned useless coordinate points include several coordinate points between two adjacent repeated coordinate points.

[0080] Further explanation is as follows:

[0081] A spatial coordinate system is established for the multifunctional emergency rescue vehicle with the rotation center of the rotary platform 1 as the coordinate origin. The working arm 3 is equivalent to an open joint structure, which can perform rotation, amplitude change, and telescopic actions. The position of the connector assembly 4 on the working arm 3 can be controlled by parameterizing the rotation angle, amplitude change angle, and telescopic length.

[0082] Correspondingly, the placement position of each working tool 2 is equivalent to a coordinate point of the spatial coordinate system. Therefore, through this spatial coordinate, the process of switching working tools can be transformed into a process of using parameters to control the mutual transformation of coordinate values. The specific implementation method is as follows:

[0083] Determine that each work tool 2 is in an initial state where the work tool support is located, and the work arm 3 and the work tool 2 are in an unconnected state;

[0084] Switch to the program debugging mode, press the function button of the working tool 2, manually operate the working arm 3 to dock the working tool 2, ensure that the first hydraulic joint 441 and the second hydraulic joint 241 are connected, close the locking pin 42, unlock the tool bracket insurance, and lift the working arm 3 to a safe position;

[0085] Exit the program debugging mode and enter the self-learning mode. The program automatically records the position coordinate information of the working arm 3 during the movement of the debugging mode, and determines the key position coordinate information through the optimization algorithm, such as the position coordinate when the working arm 3 is connected to the working machine 2. Ignore the repeated and useless action information during the movement, complete the storage of the automatic quick change program of the spatial trajectory of the working arm 3 and exit the self-learning mode;

[0086] During actual operation, after pressing the set operation function key, the stored program automatically calculates the rotation angle, amplitude variation angle and extension amount required for the working arm 3 to dock with the key position coordinates in the shortest time according to the key position coordinate information and the current rotation angle, amplitude variation angle and extension amount of the working arm 3 according to the optimization algorithm, so as to realize the rapid switching operation of the working arm 3 for the working tool 2; similarly, the rapid switching mode of the working tool 2 corresponding to each function button can be realized.

[0087] The present application is further described below with reference to the accompanying drawings:

[0088] like Figure 1 As shown, the multifunctional emergency rescue vehicle is equipped with a multi-terrain off-road chassis with high mobility and strong road adaptability, and can adapt to a variety of harsh road conditions. When the bulldozer 7 is operated in a low position, obstacle removal can be achieved. When performing multi-condition rescue operations, the frog-shaped legs 8 need to be unfolded and the whole vehicle needs to be supported and stabilized. The operator enters the operating room to control the unfolding, rotation, amplitude change and extension of the working arm 3, and quickly replaces the corresponding working machine 2 according to the rescue task to implement and complete the rescue task.

[0089] like Figure 2 As shown, the working tool 2 is explained by taking the hydraulic shears 251 as an example. When the working tool 2 is quickly switched, the connecting head assembly 4 is first manipulated to approach the working tool 2, and the connecting head assembly 4 and the working tool 2 are accurately positioned and pressed through the cooperation of the positioning pin 442 and the positioning pin hole 242, so that the first hydraulic connector 441 and the second hydraulic connector 241 are connected in place; then the locking pin shaft 42 is controlled to extend into the locking pin hole 22 and fastened in place, thereby completing the reliable connection of the mechanical and hydraulic pipelines of the working arm 3 and the working tool 2.

[0090] The quick-change devices of other working tools 2 have the same structure as the hydraulic shears 251, but differ in the number of hydraulic oil circuits, so that the working modes of different working tools 2 can be quickly switched under various rescue conditions.

[0091] Therefore, according to the disclosed embodiment, the multifunctional emergency rescue vehicle can realize the function of automatically replacing the working tool 2 on the vehicle, and according to different rescue conditions, the corresponding working tool 2 can be replaced efficiently and accurately to complete rescue tasks such as excavation, demolition, and cutting.
