[0063] The multifunctional rescue equipment provided in the embodiment of the present application includes a chassis 10 , a vehicle body 20 , a mechanical arm 30 , a quick-change device 40 , an accessory stand 50 and a control system 70 .

[0064] Among them, the chassis 10 has at least two steering modes, the vehicle body 20 is arranged on the chassis 10, the mechanical arm 30 can be movably arranged on the vehicle body 20, the mechanical arm 30 is used to move relative to the vehicle body 20, the quick-change device 40 is installed at the end of the mechanical arm 30 away from the vehicle body 20, the quick-change device 40 is provided with a first connecting structure 41, the accessory stand 50 is connected to the quick-change device 40, the accessory stand 50 is used to install at least three different accessory bodies, the accessory stand 50 and each accessory body are provided with a second connecting structure 51, the second connecting structure 51 is configured to be connected with the first connecting structure 41, the control system 70 is arranged in the control room 90 of the vehicle body 20, the control system 70 is communicatively connected with the chassis 10 and the mechanical arm 30, the control system 70 is used to control the steering of the chassis 10, and is used to control the mechanical arm 30 to assemble the corresponding accessory body.

[0065] Specifically, the mechanical arm 30 of the vehicle body 20 is equipped with an attachment stand 50, on which at least three different attachment bodies are installed, and the at least three different attachment bodies are at least three of a traction device 61, a bucket 62, a loading bucket 63, a hydraulic shear 64, a breaker hammer 65, a fork 66, and a corrugated steel support device 67. In this way, when emergency rescue is required, one device can be equipped with at least three different attachment bodies to arrive at the rescue site, and different devices can be equipped with different attachment bodies, which can increase the types of attachment bodies used. After arriving at the work site, the mechanical arm 30 of each device can select any attachment body from multiple devices to perform corresponding operations, so that emergency operations in post-disaster tunnels can be handled to a greater extent.

[0066] With such an arrangement, the multifunctional rescue equipment provided in the embodiment of the present application adopts the quick-change device 40 at the end of the mechanical arm 30 to realize the rapid interchange of various types of functional attachment bodies, realize the integration of rescue and emergency clearance, and greatly improve the operation efficiency and safety; at the same time, the attachment bodies carried by the whole machine through the quick-change device 40 include the traction device 61, the digging bucket 62, the loading bucket 63, the hydraulic shear 64, the breaker hammer 65, the fork 66, and the corrugated steel support device 67. In this way, combined with the integrated quick-change design of the multifunctional machine based on the hydraulic quick-change technology equipment, a tunnel emergency disposal mode of single equipment entry and multi-machine operation is realized, and the support, traction, shearing, lifting, crushing, excavation, loading, and lighting operations in the complex and confined space of the tunnel after the disaster are realized.

[0067] In addition, by controlling the steering of the chassis 10 and the movement of the robotic arm 30 through the control system 70, remote automatic quick change of multi-task tools is realized, so that the corresponding tool body can be assembled according to actual work needs.

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

[0069] In this embodiment, the first connection structure 41 includes a limit groove 411, a limit surface 412 and a movable latch. The limit groove 411 is provided at one end of the quick-change device 40, and the limit groove 411 is used to be embedded with the first connection shaft 511; the limit surface 412 is provided at the other end of the quick-change device 40, and the limit surface 412 is used to abut against the second connection shaft 512, and a through hole is provided on the limit surface 412; the movable latch can be movably provided inside the quick-change device 40 and can extend out of the through hole, and the movable latch is used to be inserted into the inner side of the second connection shaft 512, so that the first connection structure 41 is connected to the second connection structure 51.

[0070] It can be understood that when connecting, 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 inserted into the first connecting shaft 511. Then, with the axis of the first connecting shaft 511 as the rotating axis, the quick-change device 40 is swung toward the second connecting shaft 512 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 pin is extended through the through hole on the limiting surface 412 and inserted into the inner side of the second connecting shaft 512. In this way, the purpose of connecting the first connecting structure 41 and the second connecting structure 51 can be achieved.

[0071] In some embodiments, the first connecting structure 41 also includes a guiding curved surface 413, which is connected to the limiting surface 412. The guiding curved surface 413 is arranged on the outside of the limiting surface 412, and the guiding curved surface 413 is used to guide the second connecting shaft 512 so that the second connecting shaft 512 is guided to contact and 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. When the quick-change device 40 swings toward the second connecting shaft 512 , the second connecting shaft 512 slides toward the limiting surface 412 via the guide curved surface 413 and abuts against the limiting surface 412 .

[0073] In order to facilitate the movement of the movable pin, the first connecting structure 41 also includes a hydraulic driving component, which is connected to the movable pin. The hydraulic driving component is used to drive the movable pin to telescopically move relative to the limiting surface 412, so that after the limiting groove 411 is embedded and matched with the first connecting shaft 511, and the limiting surface 412 is abutted against the second connecting shaft 512, the movable pin extends out of the limiting surface 412, thereby fixing the corresponding accessory body to the quick-changing device 40.

[0074] In addition, in order to facilitate the connection between the quick change device 40 and the robot arm 30 , the quick change device 40 is provided with two installation shafts 42 . The two installation shafts 42 are arranged on a side of the quick change device 40 away from the first connection structure 41 , and the two installation shafts 42 are docked with the robot arm 30 .

[0075] By adopting the above-mentioned setting method, the quick-change device 40 at the end of the robot arm 30 can be used to quickly interchange the above-mentioned seven types of attachment bodies within 120 seconds, so that the telescopic robot arm 30 equipped in this application can be used to promptly carry out unmanned emergency repair and rescue work in the disaster-damaged tunnel.

[0076] In some embodiments, the accessory stand 50 includes a stand body 52, and at least three accessory mounting positions are provided on the stand body 52, and the three accessory mounting positions are arranged side by side on the stand body 52. ​​The stand body 52 is also provided with a guide structure, and the guide structure is arranged on both sides of the second connection structure 51 of the stand body 52, so that the first connection structure 41 is connected to the second connection structure 51 after being guided by the guide structure.

[0077] In some embodiments, the guide structure includes two guide plates 53 arranged opposite to each other, a plurality of reinforcing ribs 54 are arranged between any guide plate 53 and the stand body 52 , and the distance between the two guide plates 53 gradually decreases in the direction approaching the stand body 52 .

[0078] In this way, the two guide plates 53 form a flared structure. When the first connection structure 41 of the quick-change device 40 is docked with the second connection structure 51 on the stand body 52, the first connection structure 41 is guided by the two guide plates 53 and docked with the second connection structure 51. This can greatly improve the efficiency of the connection between the quick-change device 40 and the accessory stand 50.

[0079] It should be noted that when the quick-change device 40 at the end of the robot arm 30 is docked with the connecting end of the accessory stand 50, alignment errors will inevitably occur. Relying on the above-mentioned guide plate 53 with a flared structure, the auxiliary alignment of the quick change of the robot arm 30 and the accessory stand 50 can be quickly completed.

[0080] In some embodiments, an identification information reading module 80 is provided on the robot arm 30, and the identification information reading module 80 is communicatively connected with the control system 70. Each accessory body is provided with an identification information mark 81. 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 the working parameters under different working conditions for the corresponding accessory body.

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

[0082] The above-mentioned setting method realizes automatic identification of the attachment body, status monitoring and integrated intelligent matching of flow and pressure under different working conditions, breaks through the adaptive matching technology of flow and pressure between the attachment body and equipment, and realizes intelligent matching and integrated management of multi-functional tunnel reopening equipment.

[0083] Of course, wireless radio frequency identification technology (RFID) can also be used. Wireless radio frequency identification technology is a technology that uses radio waves for non-contact automatic identification. It uses radio waves to identify and exchange data with the corresponding accessory body. 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 set on the accessory body. The reader is responsible for transmitting a radio frequency signal 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, which can process the data returned by the tag and transmit it to the control system 70.

[0084] Wireless radio frequency identification technology is used for contactless two-way data communication, and wireless radio frequency is used to read and write recording media, realizing automatic identification of the accessory body, status monitoring and integrated intelligent matching of flow and pressure under different working conditions. It breaks through the adaptive matching technology of flow and pressure between the accessory body and equipment, and realizes intelligent matching and integrated management of multi-functional tunnel restoration equipment.

[0085] In some embodiments, the multifunctional rescue equipment also includes a command receiving module 100, which is communicatively connected to the control system 70, and the command receiving module 100 is used to receive the operator's accessory replacement instructions and accessory operation instructions, and transmit the accessory replacement instructions and accessory operation instructions to the control system 70.

[0086] Of course, according to actual application needs and taking into account the complex conditions at the work site, the instruction receiving module 100 can be set as a remote control device to receive the staff's operating instructions through the remote control device. The operating instructions include but are not limited to accessory replacement instructions and accessory operation instructions. For example, after receiving the accessory replacement instruction, the control system 70 controls the robot arm 30 to configure the corresponding accessory body. For another example, after receiving the accessory operation instruction, the control system 70 controls the robot arm 30 to drive the corresponding accessory body to perform related operations on site.

[0087] In some embodiments, the chassis 10 of the multifunctional rescue equipment is an integrated multi-mode steering chassis 10. Three steering modes are set for the narrow confined space of post-disaster tunnels, specifically front-wheel steering, rear-wheel steering and C-type steering mode. The C-type steering mode is composed of a common steering operating system in parallel with an electro-hydraulic control system, which cooperates with the electro-hydraulic steering gear to minimize the lateral acceleration of the articulated steering vehicle, eliminates the deviation of the steering wheel, and realizes a variable steering ratio.

[0088] Specifically, the chassis 10 includes 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 energized, the control valve core moves to the left, the left oil circuit of the front axle steering hydraulic cylinder 11 is connected with the right oil circuit of the rear axle steering hydraulic cylinder 12, and the right oil circuit of the front axle steering hydraulic cylinder 11 is connected with the left oil circuit of the rear axle steering hydraulic cylinder 12. By rotating the steering gear, the front wheel steering corresponding to the front axle steering hydraulic cylinder 11 is opposite to the rear wheel steering direction corresponding to the rear axle steering hydraulic cylinder 12, thereby realizing a four-wheel steering mode. This mode has a small steering radius and is suitable for steering in narrow areas with limited space.

[0089] In some embodiments, a power battery system 110 and a range extender system 120 are installed on the vehicle body 20 . The range extender system 120 is connected to the power battery system 110 . The range extender system 120 is used to provide power to the power battery system 110 when the power of the power battery system 110 is insufficient.

[0090] In addition, the multifunctional rescue equipment also includes a driving motor 130 and telescopic legs 140. The driving motor 130 is used to provide driving force to perform related movements, and the telescopic legs 140 is used to provide stable support to ensure the stability of the multifunctional rescue equipment when it is working.

[0091] In summary, the multifunctional rescue equipment provided in the embodiment of the present application integrates the extended-range power system, the multi-mode steering chassis 10, the multifunctional quick-interchange device, and the power battery system 110, thereby solving the problems that a single device is difficult to meet multi-task requirements, the space for multiple devices to enter is limited, and manual handling operations are dangerous. At the same time, by configuring a variety of operating tool modes with one device, an integrated special tunnel handling equipment with obstacle clearing and structural repair functions is realized, which can greatly improve the emergency response capabilities of major natural disasters, rescue disaster victims with the greatest efficiency, and minimize casualties.

[0092] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0093] The above is a detailed introduction to the multifunctional rescue equipment provided by the present application.

The description of the above embodiments is only used to help understand the scheme of the present application and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the present application.
