Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0028] like Figures 1-2 As shown in the figure, an excavator-type emergency rescue vehicle provided in this embodiment of the invention includes an emergency vehicle 1 and an excavator body 3. The emergency vehicle 1 is equipped with a hydraulic cylinder, and the excavator body 3 is provided with an excavator cab 2 and an excavator boom 8. The hydraulic cylinder is used to drive the excavator boom 8 to achieve excavation operations.

[0029] The above-mentioned technical features are all mature existing technologies, which are technical solutions that are not difficult for those skilled in the art to obtain or conceive of. Those skilled in the art can make corresponding adjustments and selections based on the above-mentioned 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 equipped with a slewing bearing 5 and a first hydraulic motor for driving the movement of the slewing bearing 5, and the excavator body 3 is mounted on the slewing bearing 5.

[0031] Auxiliary support wheel assemblies 7 are provided on both sides of the vehicle body support 4. Each auxiliary support wheel assembly 7 includes a mounting base 71, which is located on the side of the vehicle body support 4. A hydraulic push rod 75 is mounted on one side of the mounting base 71, and a rotating shaft 72 is mounted on the other side. A movable column 73 is rotatably connected to the outer side of the rotating shaft 72, and an auxiliary support wheel 74 is mounted on one end of the movable column 73. A linkage shaft 76 is mounted on one end of the hydraulic push rod 75 and the surface of the movable column 73. A hydraulic cylinder is connected to the first hydraulic motor and the hydraulic push rod 75 respectively via hydraulic oil delivery lines.

[0032] In one embodiment of the present invention, a hydraulic cylinder is installed inside the emergency vehicle 1 to drive the boom 8 on the excavator body 3 to perform digging operations. The hydraulic cylinder is connected to a first hydraulic motor and a hydraulic push rod 75 through a hydraulic oil delivery pipeline, providing the necessary power support to ensure the smooth completion of various actions of the excavator body. The excavator body 3 includes a cab 2 and a boom 8. The cab 2 is used by the operator to control the excavator, while the boom 8 is extended, retracted, or angled by the hydraulic cylinder to complete specific digging operations.

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

[0034] Two sides of the vehicle body bracket 4 are respectively provided with auxiliary support wheel assemblies 7 for improving the stability of the vehicle during operation. The auxiliary support wheel assembly 7 includes a mounting seat 71 installed on the side surface 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 with a movable column 73, and the movable column 73 is provided with an auxiliary support wheel 74 at one end. The hydraulic push rod 75 and the one end of the movable column 73 are jointly provided with a linkage shaft 76. The hydraulic push rod 75 provides a pushing force during operation, so that the auxiliary support wheel 74 can be raised or lowered as needed. The hydraulic cylinder is connected with the hydraulic push rod 75 through a hydraulic oil delivery pipeline, drives the lifting of the auxiliary support wheel, and ensures the stability of the vehicle during operation.

[0035] The beneficial effects of the technical solution mainly include the following aspects: first, it can provide efficient emergency response capability, and can quickly reach the repair site and perform emergency operation. Through the coordinated cooperation of components such as hydraulic cylinders and hydraulic motors, the rescue vehicle can not only perform excavation operations, but also can flexibly adjust the operation angle in limited space, thereby improving the operation efficiency. Second, the design of the rotary support and the auxiliary support wheel ensures the stability of the vehicle during excavation operation, avoids the inclination or instability phenomenon that may occur during operation, and enhances the safety of operation. The auxiliary support wheel assembly can automatically adjust according to the ground conditions on site, and adapt to different working environments.

[0036] In addition, the design also effectively reduces the inconvenience of traditional emergency vehicles in complex operation environment. Through the high-efficiency power support provided by the hydraulic system, the operator can conveniently control various operation actions, thereby reducing the burden of manual operation and improving the work efficiency.

[0037] When the excavation function is not used, the excavator arm can be adjusted to the upper side of the vehicle body through the hydraulic system, so as to ensure that the working space is not occupied and the normal driving of the vehicle is facilitated.

[0038] In terms of working principle, the hydraulic oil station supplies hydraulic oil to the hydraulic system through the hydraulic pump. The hydraulic oil enters the hydraulic cylinder through the hydraulic pipeline, pushing the movable arm 8 to perform excavation work. The hydraulic oil also enters the first hydraulic motor through the hydraulic pipeline, driving the rotary support 5 to realize the rotation of the excavator main body 3. The hydraulic push rod 75 adjusts the lifting of the auxiliary support wheel 74 according to the action of the hydraulic oil, ensuring the stability of the emergency vehicle during operation. The entire hydraulic system is coordinated and controlled through the hydraulic oil delivery pipeline, ensuring the cooperation and efficiency of each part.

[0039] The technical solution solves the problem of lack of flexibility and stability of traditional rescue vehicles during emergency operation, and improves the response speed and processing efficiency of rescue operation by integrating the functions of excavators and emergency vehicles. At the same time, through the application of the hydraulic system, the operating performance and operation accuracy of the equipment in complex environments are effectively improved, which has a wide application prospect, especially in urban emergency rescue, post-disaster rescue, pipeline maintenance and other emergency rescue occasions, which can greatly improve the efficiency of rescue work and save human resources.

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

[0041] The hydraulic oil is delivered to the second hydraulic motor through the hydraulic pipeline, driving 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 demand, providing the required support and movement ability.

[0042] When the emergency vehicle needs to be stably supported in different working environments, the hydraulic system coordinates the work 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 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 smoothness 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 wheel, ensuring that the emergency vehicle can operate efficiently when performing complex tasks, and enhancing the mobility and adaptability of the vehicle.

[0044] As Figure 3 and Figure 4As shown, in one embodiment of the present application, in order to increase the flexibility and operability of the emergency vehicle in operation, the surface of the vehicle body holder 4 is provided with a supporting horizontal plate 9, and the surface of the supporting horizontal plate 9 is slidingly connected with a sliding seat 10. The two sides of the supporting horizontal plate 9 are provided with first positioning sliding grooves 15, and the two sides of the inside of the sliding seat 10 are provided with positioning sliding blocks 13. The sliding seat 10 is slidingly connected to the supporting horizontal plate 9 through the cooperation of the positioning sliding blocks 13 and the first positioning sliding grooves 15. This design enables the sliding seat 10 to move horizontally on the surface of the supporting horizontal plate 9, thereby providing a larger operating range for the excavator body 3, especially in areas that are difficult to reach beside the vehicle body, and more accurate excavation operations can be performed.

[0045] The fixed seat 6 is installed on the surface of the sliding seat 10, and the surface of the sliding seat 10 and the vehicle body holder 4 is provided with a driving assembly 11 for driving the sliding seat 10 to move on the surface of the supporting horizontal 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 holder 4 and connected to the hydraulic oil cylinder through a hydraulic oil delivery pipeline. The output end of the third hydraulic motor 113 is provided with a driving gear 112, and the side surface of the sliding seat 10 is provided with a transmission rack 111, and the outer side of the transmission rack 111 is meshingly connected with the outer side of the driving gear 112. Through this gear and rack transmission mode, the third hydraulic motor driving gear 112 rotates, thereby driving the sliding seat 10 to translate along the surface of the supporting horizontal plate 9, adjusting the position of the excavator mechanism so that it can cover more operating areas.

[0046] The beneficial effects of this design are that through the horizontal movement of the sliding seat 10, the excavator body 3 can perform more extensive operations in the originally limited space, especially in the areas beside the vehicle body or near obstacles, which can make the excavator more flexible to cope with complex operating environments. The hydraulic system of the driving assembly 11 provides sufficient power to ensure the smooth movement of the sliding seat 10 and can be accurately controlled under different terrain conditions, improving the operating efficiency and operating range. The entire hydraulic system works in coordination through the hydraulic oil delivery pipeline to ensure efficient cooperation of each part. The increase of this function solves the problem that the traditional emergency rescue vehicles cannot effectively perform the excavation operation in narrow or complex environments, greatly expanding the possibility of rescue operations and having stronger adaptability and operating ability.

[0047] Through this innovative design, the adaptability of the emergency vehicle in complex terrain is greatly improved, making the rescue operation more flexible and efficient, especially suitable for emergency rescue tasks with space limitations, obstacles or narrow working areas, further enhancing the role of the vehicle in post-disaster rescue and emergency repair.

[0048] In this embodiment, the support horizontal plate 9 is a component made of iron, and the inside of the sliding seat 10 is provided with an electromagnet block 12, and the surface of the electromagnet block 12 is closely attached to the surface of the support horizontal plate 9.

[0049] When the sliding seat 10 moves to the appropriate position, the electromagnet block 12 generates a magnetic force after being energized, firmly adsorbing the sliding seat 10 on the support 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 needed, avoiding any displacement or instability of the sliding seat 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 with the support horizontal plate 9, avoiding displacement of the sliding seat 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 precision of the operation. In this way, the sliding seat 10 can be quickly fixed after completing position adjustment, improving operation efficiency and ensuring the stability of the excavation operation.

[0051] In addition, the design of the electromagnet block 12 is also controllable, when it is necessary to adjust the position of the sliding seat 10, the electromagnet can remove the adsorption force by being de-energized, 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 conveniently released when adjustment is needed, further improving the adaptability and operation convenience of the equipment.

[0052] This design effectively solves the stability problem of the sliding seat during task execution, ensuring that it will not deviate under high speed or complex operation conditions, and has high safety and reliability.

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

[0054] The surface of the extension support block 14 is provided with a second positioning sliding groove of the same specification as the first positioning sliding groove 15, which is used in cooperation with the positioning sliding block 13 on the sliding seat 10 to ensure that the sliding seat 10 can smoothly and accurately slide on the support horizontal plate 9. The design of the second positioning sliding groove enables the sliding seat 10 to have a larger operating range when performing the translation operation, thereby increasing the flexibility of the operation, especially when a larger excavation range is required or when it is impossible to approach the side of the vehicle body for operation. The extension support block can provide a longer translation distance to ensure that the device can cover a wider area.

[0055] This design effectively solves the problem of the original support horizontal plate 9 and the sliding seat 10 being limited during translation, enabling the sliding seat 10 to have more movement space when translating, thereby improving the operation range and flexibility. At the same time, the cooperation design of the extension 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 affecting the operation accuracy and efficiency due to unstable structure or position deviation.

[0056] Through this improvement, the device can better adapt to the needs of narrow or special environments during complex rescue operations, ensuring the efficiency and safety of the rescue process, while improving the applicability of the device and expanding the application range of the excavation operation.

[0057] In an embodiment of the present application, to further improve the maneuverability and operation convenience of the emergency vehicle 1, the front wheels of the emergency vehicle 1 are additionally provided with an electric power-assisted steering system, and the control panel of the electric power-assisted steering system is arranged in the excavator cab 2. The electric power-assisted steering system is installed on the front wheel steering mechanism in parallel with the original hydraulic steering system of the emergency vehicle 1, enabling the operator to more accurately adjust the direction of travel of the vehicle. By controlling the system, the left and right steering of the front wheels of the emergency vehicle 1 can be realized, thereby flexibly adjusting the travel path of the vehicle, 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 for real-time observation of the environment and obstacles around the vehicle. The video display picture is directly transmitted to the excavator cab 2 to provide the operator with a full range of visual support. During travel, the operator can use the multi-directional video display system to real-time understand the road conditions around the vehicle, avoid potential collisions or obstacles interference, and thus select the optimal travel mode to improve the safety and efficiency of the operation.

[0059] When the emergency vehicle 1 reaches the work site that needs to be excavated, the hydraulic oil cylinder will extend, making the auxiliary support wheels 74 in the auxiliary support wheel assembly 7 contact the ground and play a supporting role. During travel, the auxiliary support wheels 74 work with the electric power steering system of the front wheels of the emergency vehicle 1, providing additional power support to ensure the stability and maneuverability of the vehicle on complex terrain. By adjusting the direction of the front wheels through the electric power steering system and observing in real time through the multi-directional video display system, the operator can flexibly control the left and right travel direction of the vehicle, ensuring that the emergency vehicle 1 can accurately reach the target position and create better conditions for subsequent excavation operations. This design significantly improves the overall efficiency and safety of rescue operations, especially in narrow and complex terrain environments.

[0060] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
