[0068] In some embodiments, the second connecting structure 51 includes a first connecting shaft 511 and a second connecting shaft 512, and the first connecting shaft 511 is parallel to the second connecting shaft 512.

[0069] In this embodiment, the first connecting structure 41 includes a limiting groove 411, a limiting surface 412, and a movable bolt. The limiting groove 411 is arranged at one end of the quick-change device 40 and is used for embedding and cooperating with the first connecting shaft 511. The limiting surface 412 is arranged at the other end of the quick-change device 40 and is used for abutting against the second connecting shaft 512. The limiting surface 412 is provided with a through hole. The movable bolt is movably arranged inside the quick-change device 40 and can extend out of the through hole. The movable bolt is used for being inserted into the inner side of the second connecting shaft 512, so that the first connecting structure 41 is connected with the second connecting structure 51.

[0070] It can be understood that when connected, the manipulator drives the quick-change device 40 to assemble with the corresponding accessory body. First, the limiting groove 411 at one end of the quick-change device 40 is clamped into the first connecting shaft 511. Then, the quick-change device 40 is swung towards the second connecting shaft 512 with the first connecting shaft 511 as the pivot, until the other end of the quick-change device 40 is pressed into the second connecting shaft 512, and the limiting surface 412 abuts against the second connecting shaft 512. Finally, the movable bolt extends out of the through hole on the limiting surface 412 and is inserted into the inner side of the second connecting shaft 512. In this way, the first connecting structure 41 and the second connecting structure 51 can be connected.

[0071] In some embodiments, the first connecting structure 41 further comprises a guide curved surface 413 connected with the limiting surface 412, the guide curved surface 413 is arranged outside the limiting surface 412, and the guide curved surface 413 is used for guiding the second connecting shaft 512 so as to guide the second connecting shaft 512 to abut against the limiting surface 412.

[0072] Specifically, the guide curved surface 413 and the limiting surface 412 form an S-shaped curved surface structure, during the swinging of the quick-change device 40 towards the second connecting shaft 512, the second connecting shaft 512 slides to the limiting surface 412 through the guide curved surface 413 and abuts against the limiting surface 412.

[0073] In order to facilitate the movement of the movable bolt, the first connecting structure 41 further comprises a hydraulic drive connected with the movable bolt, the hydraulic drive is used to drive the movable bolt to extend and retract relative to the limiting surface 412, so that the movable bolt extends out of the limiting surface 412 after the limiting groove 411 and the first connecting shaft 511 are fitted and the limiting surface 412 and the second connecting shaft 512 abut, thereby fixing the corresponding tool body to the quick-change device 40.

[0074] In addition, in order to facilitate the connection of the quick-change device 40 and the mechanical arm 30, the quick-change device 40 is provided with two mounting shafts 42 arranged on the side of the quick-change device 40 away from the first connecting structure 41, and the two mounting shafts 42 are connected with the mechanical arm 30.

[0075] By using the above arrangement, the quick-change device 40 at the end of the mechanical arm 30 can be used to complete the quick exchange of the above seven tool bodies within 120s, so as to cooperate with the telescopic mechanical arm 30 on the equipment to timely carry out unmanned rescue and rescue work in a disaster tunnel.

[0076] In some embodiments, the tool rack 50 comprises a rack body 52, and the rack body 52 is provided with at least three tool mounting positions, and the three tool mounting positions are arranged side by side on the rack body 52. The rack body 52 is further provided with a guide structure arranged on both sides of the second connecting structure 51 of the rack body 52, so that the first connecting structure 41 is guided by the guide structure and connected with the second connecting structure 51.

[0077] In some embodiments, the guide structure comprises two oppositely arranged guide plates 53, and a plurality of reinforcing rib plates 54 are arranged between any one of the guide plates 53 and the rack body 52, and the distance between the two guide plates 53 gradually decreases in the direction close to the rack body 52.

[0078] In this way, the two guide plates 53 form a flared structure, when the first connecting structure 41 of the quick-change device 40 is docked with the second connecting structure 51 on the gantry body 52, the first connecting structure 41 is guided by the two guide plates 53 and then docked with the second connecting structure 51, so that the efficiency of connecting the quick-change device 40 with the tool gantry 50 can be greatly improved.

[0079] It should be noted that when the quick-change device 40 at the end of the mechanical arm 30 is docked with the connecting end of the tool gantry 50, alignment errors will inevitably occur. By means of the guide plates 53 with the flared structure, the auxiliary alignment of the quick-change of the mechanical arm 30 and the tool gantry 50 can be quickly completed.

[0080] In some embodiments, the mechanical arm 30 is provided with an identification information reading module 80, which is in communication with the control system 70. Each tool body is provided with an identification information mark 81, and the identification information reading module 80 is used to collect the identification information mark 81 and transmit it to the control system 70, so that the control system 70 can configure different working parameters for the corresponding tool body under different working conditions.

[0081] Specifically, the above-mentioned identification information mark 81 can be a bar code or a two-dimensional code, which contains the model or type information of the corresponding tool body. The identification information reading module 80 can be a code scanner. By scanning the bar code or two-dimensional code on the corresponding tool body through the code scanner on the mechanical arm 30, the model or type information of the corresponding tool body can be accurately obtained and transmitted to the control system 70, so that the control system 70 can configure different working parameters (such as working pressure and working flow) for the corresponding tool body under different working conditions.

[0082] By adopting the above-mentioned setting mode, automatic identification, state monitoring and integrated intelligent matching of flow and pressure under different working conditions of the tool body are realized, the adaptive matching technology of the tool body and the equipment flow and pressure is broken through, and intelligent matching and integrated management of the multifunctional tunnel reconnection machine tool are realized.

[0083] Of course, radio frequency identification technology (RFID) can also be used. Radio frequency identification technology is a non-contact automatic identification technology using radio waves. It realizes the identification and data exchange of the corresponding tool body through radio waves. In this embodiment, the RFID system is usually composed of three basic components: an electronic tag (Tag), a reader (Reader) and a control system 70. The electronic tag is arranged on the tool body, and the reader is responsible for transmitting radio frequency signals to activate the tag and receiving the information returned by the tag. The reader is usually composed of a coupling module, a transceiver module, a control module and an interface unit, and can process the data returned by the tag and transmit it to the control system 70.

[0084] The wireless radio frequency identification technology is used for non-contact two-way data communication, and the wireless radio frequency is used for reading and writing the recording medium, so as to realize automatic identification of the tool body, state monitoring and integrated intelligent matching of flow pressure under different working conditions, break through the adaptive matching technology of the tool body and the equipment flow pressure, and realize intelligent matching and integrated management of the multifunctional tunnel reconditioning machine.

[0086] Of course, according to the actual application needs, considering the complex situation of the working site, the instruction receiving module 100 can be set as a remote control device to receive the operation instruction of the worker, which includes but is not limited to the tool replacement instruction and the tool operation instruction, for example, after receiving the tool replacement instruction, the control system 70 controls the mechanical arm 30 to configure the corresponding tool body, and for another example, after receiving the tool operation instruction, the control system 70 controls the mechanical arm 30 to drive the corresponding tool body to perform the related work on site.

[0087] In some embodiments, the chassis 10 of the multifunctional rescue equipment is an integrated multi-mode steering chassis 10, which is provided with three steering modes, i.e., front wheel steering, rear wheel steering and C-type steering mode, for the limited space of the narrow post-disaster tunnel. The C-type steering mode is connected in parallel with a common steering operation system and an electric-hydraulic control system, and cooperates with an electric-hydraulic steering gear to minimize the lateral acceleration of the articulated steering vehicle, so as to eliminate the deviation of the steering wheel, i.e., to realize the variable steering ratio.

[0088] Specifically, the chassis 10 comprises a steering gear, a front axle steering hydraulic cylinder 11, a rear axle steering hydraulic cylinder 12 and a steering mode valve 13. In the C-type steering mode, after the electromagnet of the steering mode valve 13 is powered on, the valve core moves left, the left oil way of the front axle steering hydraulic cylinder 11 is communicated with the right oil way of the rear axle steering hydraulic cylinder 12, and the right oil way of the front axle steering hydraulic cylinder 11 is communicated with the left oil way of the rear axle steering hydraulic cylinder 12. By rotating the steering gear, the front wheel corresponding to the front axle steering hydraulic cylinder 11 is steered in the opposite direction of the rear wheel corresponding to the rear axle steering hydraulic cylinder 12, so as to realize the four-wheel steering mode. The steering radius of this mode is small, and is suitable for steering in a narrow area with limited space.

[0089] In some embodiments, the vehicle body 20 is provided with a power battery system 110 and a range extender system 120. The range extender system 120 is connected with the power battery system 110, and is configured to provide electric energy for the power battery system 110 when the electric energy of the power battery system 110 is insufficient.

[0090] In addition, the multifunctional rescue equipment further comprises a driving motor 130 and telescopic legs 140, the driving motor 130 is used to provide driving force to perform relevant movements, and the telescopic legs 140 are used to provide stable support to ensure the stability of the multifunctional rescue equipment during work.
