DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0028] like Figure 1-Figure 2 As shown, an embodiment of the present invention provides an excavation-type emergency rescue vehicle, which includes an emergency vehicle 1 and an excavator body 3. A hydraulic cylinder is installed inside the emergency vehicle 1, and an excavator cab 2 and an excavator movable arm 8 are provided on the excavator body 3. The hydraulic cylinder is used to drive the excavator movable arm 8 to realize excavation operations.

[0029] The above technical features are all mature existing technologies, and are technical solutions that are not difficult for technical personnel in the field to obtain or think of. Technical personnel in the field can make corresponding adjustments and selections based on the above technical solutions.

[0030] The surface of the emergency vehicle 1 is provided with a vehicle body support 4, and the surface of the vehicle body support 4 is provided with a fixed seat 6, the surface of the fixed seat 6 is installed with a slewing support 5 and a first hydraulic motor for driving the slewing support 5 to move, and the excavator body 3 is arranged on the slewing support 5.

[0031] Auxiliary support wheel assemblies 7 are provided on both sides of the vehicle body bracket 4. The auxiliary support wheel assembly 7 includes a mounting seat 71, and the mounting seat 71 is provided on the side of the vehicle body bracket 4, a hydraulic push rod 75 is installed on one side of the mounting seat 71, and a rotating shaft 72 is installed on the other side of the mounting seat 71, and a movable column 73 is rotatably connected to the outer side of the rotating shaft 72, and an auxiliary support wheel 74 is installed at one end of the movable column 73, and a linkage shaft 76 is installed on one end of the hydraulic push rod 75 and the surface of the movable column 73. The hydraulic cylinder is connected to the first hydraulic motor and the hydraulic push rod 75 through a hydraulic oil delivery pipeline.

[0032] In one embodiment of the present invention, a hydraulic cylinder is installed inside the emergency vehicle 1 to drive the movable arm 8 on the excavator body 3 to achieve excavation operations. The hydraulic cylinder is connected to the first hydraulic motor and the hydraulic push rod 75 through a hydraulic oil delivery pipeline to provide necessary power support to ensure that various actions of the excavator body are completed smoothly. The excavator body 3 includes a cab 2 and a movable arm 8. The cab 2 is used by the operator to control the excavator, and the movable arm 8 is extended or adjusted in angle by the drive of the hydraulic cylinder to complete specific excavation operations.

[0033] The surface of the emergency vehicle 1 is provided with a vehicle body support 4, on which a fixing seat 6 is mounted, and on which a slewing support 5 is provided. The slewing support 5 is driven by a first hydraulic motor to rotate, allowing the excavator body 3 to adjust its direction within a certain range, so as to perform various complex rescue tasks. Through the rotation of the slewing support, the excavator can flexibly rotate in a narrow space and perform precise excavation operations.

[0034] Auxiliary support wheel assemblies 7 are respectively provided on both sides of the vehicle body bracket 4 to improve the stability of the vehicle during operation. The auxiliary support wheel assembly 7 includes a mounting seat 71, which is mounted on the side of the vehicle body bracket 4. A hydraulic push rod 75 and a rotating shaft 72 are installed in the mounting seat 71. The outer side of the rotating shaft 72 is rotatably connected to a movable column 73, and an auxiliary support wheel 74 is installed at one end of the movable column 73. A linkage shaft 76 is installed together with one end of the hydraulic push rod 75 and the movable column 73. The hydraulic push rod 75 provides thrust during operation, so that the auxiliary support wheel 74 can be raised and lowered as needed. The hydraulic cylinder is connected to the hydraulic push rod 75 through a hydraulic oil delivery pipeline to drive the lifting and lowering of the auxiliary support wheel to ensure the stability of the vehicle during operation.

[0035] The beneficial effects of this technical solution are mainly reflected in the following aspects: First, it can provide efficient emergency response capabilities, can quickly reach the repair site and perform emergency operations. Through the coordination of components such as hydraulic cylinders and hydraulic motors, the rescue vehicle can not only perform excavation operations, but also flexibly adjust the operating angle within a limited space, thereby improving operating efficiency. Secondly, the design of the slewing support and auxiliary support wheels ensures the stability of the vehicle during excavation operations, avoids possible tilting or instability during operations, and enhances the safety of operations. The auxiliary support wheel assembly can automatically adjust according to the on-site ground conditions to adapt to different working environments.

[0036] In addition, the design also effectively reduces the inconvenience of traditional emergency vehicles in complex operating environments. Through the efficient power support provided by the hydraulic system, operators can easily control various operating actions, reducing the burden of manual operation and improving work efficiency.

[0037] When the excavation function is not in use, the excavator arm can be adjusted above the vehicle body through the hydraulic system to ensure that the working space is not occupied and to facilitate the normal driving of the vehicle.

[0038] In terms of working principle, the hydraulic oil station supplies hydraulic oil to the hydraulic system through a hydraulic pump, and the hydraulic oil enters the hydraulic cylinder through the hydraulic pipeline to push the movable arm 8 to perform excavation operations; the hydraulic oil also enters the first hydraulic motor through the hydraulic pipeline to drive the slewing support 5 to realize the rotation of the excavator body 3. The hydraulic push rod 75 adjusts the lifting and lowering of the auxiliary support wheel 74 according to the action of the hydraulic oil to ensure that the emergency vehicle remains stable during the operation. The entire hydraulic system is coordinated and controlled through the hydraulic oil delivery pipeline to ensure that each part works in a coordinated and efficient manner.

[0039] This technical solution solves the problem of traditional rescue vehicles lacking flexibility and stability during emergency operations. By integrating the functions of excavators and emergency vehicles, the response speed and processing efficiency of rescue operations are improved. At the same time, through the application of hydraulic systems, the operating performance and operation accuracy of equipment in complex environments are effectively improved. It has broad application prospects, especially in emergency rescue situations such as urban emergency rescue, post-disaster rescue, and pipeline maintenance. It can greatly improve the efficiency of rescue work and save human resources.

[0040] In this embodiment, a second hydraulic motor is installed on the surface of the movable column 73, and the output end of the second hydraulic motor is fixedly connected to the axle of the auxiliary support wheel 74, and the second hydraulic motor is connected to the hydraulic cylinder through a hydraulic oil delivery pipeline.

[0041] The hydraulic oil is delivered to the second hydraulic motor through the hydraulic pipeline to drive the rotation of the auxiliary support wheel 74. The power of the second hydraulic motor enables the auxiliary support wheel 74 to rotate according to the operation requirements, providing the required support and mobility.

[0042] When the emergency vehicle needs to be stably supported in different working environments, the hydraulic system coordinates and controls the operation of the hydraulic cylinder and the second hydraulic motor to ensure that the auxiliary support wheel 74 can be flexibly adjusted. The hydraulic cylinder controls the lifting and lowering of the auxiliary support wheel through the hydraulic push rod, while the second hydraulic motor is responsible for driving the rotation of the auxiliary support wheel, so that the auxiliary support wheel can provide additional support force, increase the stability of the vehicle body, and ensure the stability and safety of the emergency vehicle during operation.

[0043] Through this design, the second hydraulic motor provides the necessary power support for the rotation of the auxiliary support wheels, ensuring that the emergency vehicle can operate efficiently when performing complex tasks and enhancing the vehicle's maneuverability and adaptability.

[0044] like Figure 3 and Figure 4As shown, in one embodiment of the present invention, in order to increase the flexibility and operability of the emergency vehicle during operation, a support cross plate 9 is provided on the surface of the vehicle body bracket 4, and a sliding seat 10 is slidably connected to the surface of the support cross plate 9. First positioning slide grooves 15 are provided on both sides of the support cross plate 9, and positioning sliders 13 are provided on both sides of the sliding seat 10. The sliding seat 10 is slidably connected to the support cross plate 9 through the cooperation of the positioning sliders 13 and the first positioning slide grooves 15. This design enables the sliding seat 10 to move horizontally on the surface of the support cross plate 9, thereby providing a larger operating range for the excavator body 3, especially in the hard-to-reach areas next to the vehicle body, so that more precise excavation operations can be performed.

[0045] The fixed seat 6 is installed on the surface of the sliding seat 10. The surfaces of the sliding seat 10 and the vehicle body support 4 are jointly provided with a driving assembly 11. The driving assembly 11 is used to drive the sliding seat 10 to move on the surface of the supporting cross plate 9. The driving assembly 11 includes a third hydraulic motor 113, and the third hydraulic motor 113 is installed on the surface of the vehicle body support 4. The third hydraulic motor 113 is connected to the hydraulic cylinder through a hydraulic oil delivery pipeline. A driving gear 112 is installed at the output end of the third hydraulic motor 113, and a transmission rack 111 is provided on the side of the sliding seat 10, and the outer side of the transmission rack 111 is meshed and connected with the outer side of the driving gear 112. Through this gear and rack transmission mode, the third hydraulic motor drives the gear 112 to rotate, thereby driving the sliding seat 10 to translate along the surface of the supporting cross plate 9, adjusting the position of the excavator mechanism so that it can cover more working areas.

[0046] The beneficial effect of this design is that through the horizontal movement of the sliding seat 10, the excavator body 3 can perform a wider range of operations in an originally limited space, especially in areas next to the vehicle body or near obstacles, which enables the excavator to cope with complex working environments more flexibly. The hydraulic system of the drive assembly 11 provides sufficient power to ensure the smooth movement of the sliding seat 10, and can be precisely controlled under different terrain conditions to improve working efficiency and working range. The entire hydraulic system coordinates work through the hydraulic oil delivery pipeline to ensure efficient coordination of the actions of each part. The addition of this function solves the problem that traditional emergency rescue vehicles cannot effectively perform excavation operations in narrow or complex environments, greatly expands the possibility of rescue operations, and has stronger adaptability and working capabilities.

[0047] Through this innovative design, the emergency vehicle's ability to respond in complex terrain is greatly improved, making rescue operations more flexible and efficient. It is particularly suitable for emergency rescue missions with space limitations, obstacles or small working areas, further enhancing the vehicle's role in post-disaster rescue and emergency repairs.

[0048] In this embodiment, the supporting transverse plate 9 is a member made of iron, an electromagnet block 12 is installed inside the sliding seat 10 , and the surface of the electromagnet block 12 is in close contact with the surface of the supporting transverse plate 9 .

[0049] When the sliding seat 10 moves to a suitable position, the electromagnet block 12 generates magnetic force after power is turned on, and the sliding seat 10 is firmly adsorbed on the supporting horizontal plate 9, thereby ensuring that the sliding seat 10 remains stable at the desired position. The electromagnet block 12 adjusts the strength of the magnetic force by controlling the current, and can provide sufficient adsorption force when necessary to prevent the sliding seat from any displacement or instability during operation.

[0050] During operation, when the sliding seat 10 completes position adjustment and reaches the set position, the electromagnet block 12 is energized to generate a magnetic field, ensuring that the sliding seat 10 is firmly adsorbed to the supporting cross plate 9, and preventing the sliding seat from being displaced due to external force or vibration. The adsorption force of the electromagnet can accurately fix the position of the sliding seat 10, improving the stability and accuracy of the operation. In this way, the sliding seat 10 can be quickly fixed after the position adjustment is completed, improving the operation efficiency and ensuring the stability of the excavation operation.

[0051] In addition, the design of the electromagnet block 12 is also controllable. When the position of the sliding seat 10 needs to be adjusted, the electromagnet can be powered off to release the adsorption force, so that the sliding seat can move freely. This design simplifies the mechanical structure and provides a flexible control method, so that the sliding seat 10 can be firmly fixed when needed, and can be easily released when adjustment is required, further improving the adaptability and ease of operation of the device.

[0052] This design effectively solves the stability problem of the sliding seat when performing tasks, ensuring that it will not deviate under high-speed or complex operating conditions, and has higher safety and reliability.

[0053] In this embodiment, the surface of the support cross plate 9 is connected with an extended support block 14 to increase the translation length of the sliding seat 10. The lower surface of the extended support block 14 is connected with a second fixed block 17, and the second fixed block 17 is fixedly connected to the first fixed block 16 by a fastening bolt 18. Specifically, the first fixed block 16 is connected to both sides of the lower surface of the support cross plate 9, and the lower surface of the extended support block 14 is connected with the second fixed block 17. The surfaces of the first fixed block 16 and the second fixed block 17 are both provided with fastening threaded holes of the same specification, and the two fixed blocks are firmly connected together by the fixing bolt 18, thereby ensuring the stable installation of the extended support block 14 on the support cross plate 9.

[0054] The surface of the extended support block 14 is provided with a second positioning slot of the same specification as the first positioning slot 15, so as to cooperate with the positioning slider 13 on the sliding seat 10 to ensure that the sliding seat 10 can slide smoothly and accurately on the supporting cross plate 9. The design of the second positioning slot enables the sliding seat 10 to obtain a larger operating range when performing translation operation, thereby increasing the flexibility of the operation, especially when a larger excavation range is required or it is impossible to operate close to the side of the vehicle body, a longer translation distance can be provided by extending the support block, thereby ensuring that the equipment can cover a farther area.

[0055] This design effectively solves the problem that the original supporting cross plate 9 and the sliding seat 10 are limited during the translation process, so that the sliding seat 10 can obtain more moving space during the translation, thereby improving the operating range and flexibility. At the same time, the matching design of the extended support block 14 and the fixed block ensures that the sliding seat 10 can still maintain good stability and accuracy during the extended translation process, avoiding the influence of the operating accuracy and efficiency due to structural instability or position offset.

[0056] Through this improvement, the equipment can better adapt to the needs in small or special environments when conducting complex rescue operations, ensuring the efficiency and safety of the rescue process. At the same time, it improves the applicability of the equipment and expands the application scope of excavation operations.

[0057] In one embodiment of the present invention, in order to further improve the maneuverability and operational convenience of the emergency vehicle 1, the front wheels of the emergency vehicle 1 are additionally equipped with an electric power steering system, and its control panel is arranged in the excavator cab 2. The electric power steering system is installed on the front wheel steering mechanism in parallel with the original hydraulic steering system of the emergency vehicle 1, so that the operator can adjust the direction of travel of the vehicle more accurately. By controlling the system, the left and right steering of the front wheels of the emergency vehicle 1 can be realized, so as to flexibly adjust the vehicle's travel path, which is particularly suitable for rescue tasks in narrow spaces or complex environments.

[0058] The emergency vehicle 1 is also equipped with a multi-directional video display system, which is installed on the surrounding structure of the emergency vehicle 1 and is used to observe the environment and obstacles around the vehicle in real time. The video display screen is directly transmitted to the excavator cab 2 to provide the operator with a full range of visual support. During the driving process, the operator can use the multi-directional video display system to understand the road conditions around the vehicle in real time, avoid potential collisions or obstacles, and thus choose the best driving method to improve the safety and efficiency of the operation.

[0059] When the emergency vehicle 1 arrives at the work site that needs to be excavated, the hydraulic cylinder will extend, so that the auxiliary support wheel 74 in the auxiliary support wheel assembly 7 contacts the ground and plays a supporting role. During the journey, the auxiliary support wheel 74 works with the electric power steering system of the front wheel of the emergency vehicle 1 to provide additional power support to ensure the stability and maneuverability of the vehicle in complex terrain. By adjusting the direction of the front wheels through the electric power steering system and cooperating with the real-time observation of the multi-directional video display system, the operator can flexibly control the left and right travel direction of the vehicle to ensure that the emergency vehicle 1 can accurately reach the target location and create better conditions for subsequent excavation operations. This design significantly improves the overall efficiency and safety of rescue operations, and has important application value, especially in emergency operations in narrow and complex terrain environments.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
