and the frog-shaped supporting legs 8 are protrudably arranged on the multi-terrain off-road chassis 6 and are configured to be unfolded outwards and downwards to support the emergency rescue vehicle on the ground when the emergency rescue device carries out emergency rescue operation.

The multi-terrain off-road chassis 6 is high in maneuverability and strong in road surface adaptability, and can adapt to various severe road conditions; the dozer blade 7 is arranged at the head position of the multi-terrain off-road chassis 6 in a liftable manner, so that ground obstacle clearing operation is realized when the dozer blade is at a low position, the traffic capacity of the multi-terrain off-road chassis 6 is improved when the dozer blade is at a high position, and transition transportation of the multifunctional emergency rescue vehicle is ensured; and the frog-shaped leg 8 can be unfolded to support and stabilize the whole vehicle.

Specifically, in some embodiments, the drive assembly 5 is further configured to:

in a program debugging mode, recording position coordinate information and motion information on a path of the connector assembly 4 which is manually operated and moves from an initial position to a target coordinate point;

and in the storage mode, combining the optimized path with the motion information on the key coordinate point, and storing the combined optimized path and the motion information as a preset path.

In a preferred embodiment, the key coordinate points may be position coordinate points where motion information changes, that is, when the connector assembly 4 is located at the key coordinate points, a new change trend is generated by changes of three parameters, namely, the rotation angle, the luffing angle and the telescoping length; the repeated coordinate points comprise two coordinate points of which the position coordinate information is completely repeated between two adjacent key coordinate points; the useless coordinate points include a plurality of coordinate points between two adjacent repeated coordinate points.

Further explanation is as follows:

a space coordinate system is established for the multifunctional emergency rescue vehicle by taking the rotation center of the rotation platform 1 as the origin of coordinates. The operation arm 3 is equivalent to an open joint structure, can perform rotation, amplitude variation and stretching actions, and can control the position of the connector assembly 4 on the operation arm 3 through parameterization of a rotation angle, an amplitude variation angle and a stretching length.

Accordingly, the placement position of each work implement 2 corresponds to a coordinate point of the spatial coordinate system. Therefore, the process of switching the working machine can be converted into the process of utilizing the parameter to control the coordinate value to be transformed mutually through the space coordinate, and the specific realization method is as follows:

determining the initial state of each working implement 2 in the implement support, and the working arm 3 and the working implement 2 are in an unconnected state;

switching to a program debugging mode, pressing down a function key of the operation machine tool 2, manually operating the operation arm 3 to butt joint the operation machine tool 2, ensuring that the first hydraulic joint 441 and the second hydraulic joint 241 are completely connected, closing the locking pin shaft 42, unlocking the safety of the machine tool bracket, and lifting the operation arm 3 to a safe position;

exiting the program debugging mode, entering a self-learning mode, automatically recording position coordinate information of the operation arm 3 in the movement process during the debugging mode by the program, and determining key position coordinate information through an optimization algorithm, such as the position coordinate when the operation arm 3 is connected with the operation tool 2. The repeated and useless action information in the movement process is ignored, the storage of the space track automatic quick change program of the operation arm 3 is completed, and the self-learning mode is exited;

in actual operation, after the set operation function key is pressed, the storage program automatically calculates the rotation angle, the amplitude variation angle and the elongation of the operation arm 3, which are required to operate for butting the key position coordinate in the shortest time, according to the optimization algorithm and the key position coordinate information and the rotation angle, the amplitude variation angle and the elongation of the current operation arm 3, so that the operation arm 3 can rapidly switch the operation machine tool 2; in the same way, the quick switching mode of the working machine 2 corresponding to each function key can be realized.

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

as shown in figure 1, the multifunctional emergency rescue vehicle is provided with a multi-ground cross-country chassis, has high maneuverability and strong road surface adaptability, and can adapt to various severe road conditions. When the operation blade 7 is positioned at a low position, obstacle clearing operation can be realized. When multi-working-condition rescue operation is carried out, the frog-shaped supporting legs 8 need to be unfolded and the whole vehicle needs to be stably supported. The operator enters the operation room to control the operation arm 3 to unfold, rotate, change amplitude, stretch and the like, and quickly change the corresponding operation machine 2 according to the rescue task to implement and complete the rescue task.

As shown in fig. 2, the working implement 2 is described by taking the hydraulic shears 251 as an example, when the working implement 2 is switched rapidly, the connector assembly 4 is firstly operated to approach the working implement 2, and the connector assembly 4 and the working implement 2 are accurately positioned and pressed through the matching of the positioning pins 442 and the positioning pin holes 242, so that the first hydraulic connector 441 and the second hydraulic connector 241 are connected in place; the locking pin 42 is then controlled to extend into the locking pin hole 22 and be tightened in place to complete a secure connection of the work arm 3 to the mechanical and hydraulic lines of the work implement 2.

The quick-change devices of the other work machines 2 have the same design as the hydraulic shears 251, except for the number of hydraulic lines. Therefore, the working modes of different working machines 2 can be quickly switched under various rescue working conditions.

Therefore, according to the embodiment of the disclosure, the multifunctional emergency rescue vehicle can realize the function of automatically replacing the working tools 2 on the vehicle, and efficiently and accurately replace the corresponding working tools 2 according to different rescue working conditions, so as to complete rescue tasks such as excavation, breaking and dismantling, cutting and the like.
