[0078] See also Figures 1 to 8 This embodiment relates to a rescue vehicle, wherein the rescue vehicle in this embodiment is a vehicle-mounted gas turbine power supply rescue vehicle, or in other embodiments the rescue vehicle is an emergency rescue equipment vehicle, etc.

[0079] The rescue vehicle includes a frame 1, which serves as the vehicle's framework and foundation. It supports and connects the vehicle's various assemblies, ensuring they maintain relative positioning and bearing various internal and external loads. The frame 1 is the vehicle's foundational support structure, providing load-bearing and stability for the entire vehicle.

[0080] The carriage 2 is arranged on the frame 1; the carriage 2 and the frame 1 are detachably connected by bolts, which is convenient for maintenance; when the rescue equipment does not need maintenance, the carriage 2 is fixed to the frame 1 by bolts. When the rescue equipment needs maintenance, the bolts between the carriage 2 and the frame 1 need to be removed. The carriage 2 is in the shape of a shell and is placed on the frame 1. Equipment, tools and materials required for rescue can be placed in the carriage 2 and on the frame 1. In the rescue vehicle in this embodiment, rescue equipment such as gas turbines and generator sets are mainly placed in the carriage 2. It should be noted that the rescue vehicle in this embodiment does not solve the problem of how gas turbines and generator sets achieve power generation. Therefore, there is no schematic diagram of the relevant rescue equipment in the drawings of the specification of this embodiment.

[0081] And a first sliding mechanism 3, which is arranged between the frame 1 and the connection between the carriage 2 and the first sliding mechanism 3. The first sliding mechanism 3 is a mechanism for achieving relative sliding of the carriage 2 in the length direction of the frame 1. The first sliding mechanism 3 is used to drive the carriage 2 to slide back and forth along the length direction of the frame 1. The design of the first sliding mechanism 3 enables the carriage 2 to slide out along the length direction of the frame 1, fully exposing the interior space of the carriage 2. There is no need to hoist the carriage 2 as a whole, which facilitates quick inspection and maintenance, effectively shortens maintenance time, and improves work efficiency. At the same time, it avoids component damage that may be caused by hoisting as a whole, reducing maintenance costs.

[0082] Specifically, in the rescue vehicle of this embodiment, when the rescue equipment in the car 2 needs to be maintained, the bolts between the car 2 and the frame 1 are removed, and then by applying a certain force outward in the longitudinal direction of the car 2, the car 2 can be slid outward along the longitudinal direction of the frame 1 through the first sliding mechanism 3, thereby fully exposing the internal space of the car 2. It is convenient to quickly inspect and maintain the rescue equipment in the car 2 and on the frame 1. The operation is simple, effectively shortens the maintenance time, improves work efficiency, and does not require vertical space. Maintenance can be carried out in a general factory building. At the same time, it avoids component damage that may be caused by overall lifting, reducing maintenance costs. When maintenance is completed, by applying a certain force inward in the longitudinal direction of the car 2, the car 2 is slid inward along the longitudinal direction of the frame 1 and pushed to reset, and finally the car 2 is fixed to the frame 1 with bolts.

[0083] Optionally, in some embodiments, Figure 4 and Figure 5As shown, the first sliding mechanism 3 includes two slide rails 31 and multiple sliding assemblies 32. The two slide rails 31 are respectively arranged on the left and right sides of the width direction of the frame 1. The two slide rails 31 are relatively symmetrically arranged and are fixedly connected to the frame 1 by welding. The multiple sliding assemblies 32 are respectively arranged on the left and right sides of the bottom of the car body 2 in the longitudinal direction. The multiple sliding assemblies 32 are evenly spaced and fixedly connected to the car body 2. The multiple sliding assemblies 32 cooperate with the two slide rails 31 to drive the car body 2 to slide back and forth along the length direction of the frame 1. The multiple sliding assemblies 32 cooperate with the two slide rails 31 to improve the stability and smoothness of the sliding of the car body 2 on the frame 1. The multiple sliding assemblies 32 are distributed at the bottom of the car body 2, which can evenly distribute the weight of the car body 2 to the slide rails 31 of the frame 1, thereby ensuring uniform load bearing and improving load-bearing capacity. Multiple sliding assemblies 32 are spaced apart at the bottom of the carriage 2, supporting and guiding the carriage 2 from different positions, enhancing stability and preventing tilting and shaking. These multiple sliding assemblies 32 distribute the workload, reduce the risk of failure, and facilitate maintenance and inspection. In this embodiment, the number of sliding assemblies 32 is not limited and can be set based on actual needs. In this embodiment, there are eight sliding assemblies 32, four on each side.

[0084] Optionally, in some embodiments, Figure 4 and Figure 5 As shown, the sliding assembly 32 includes a first mounting base 321 and at least two first pulleys 322. The first mounting base 321 is fixedly connected to the carriage 2 via bolts or welding. The at least two first pulleys 322 are respectively arranged on the left and right sides of the first mounting base 321 to provide uniform load bearing and improve load-bearing capacity. The at least two first pulleys 322 are symmetrically arranged to improve the sliding stability of the carriage 2. The at least two first pulleys 322 are respectively detachably connected to the first mounting base 321 to facilitate maintenance. The at least two first pulleys 322 respectively cooperate with the bottom surface of the slide rail 31 to support the carriage 2 to slide back and forth along the length of the frame 1, ensuring smooth movement of the carriage 2 along the slide rail 31. The at least two first pulleys 322 distribute the workload, reduce the risk of failure, and facilitate maintenance and inspection. In this embodiment, the number of first pulleys 322 is not limited and can be set according to actual conditions. In this embodiment, each sliding assembly 32 has four first pulleys 322, two on each side.

[0085] Specifically, in this embodiment, Figure 4 and Figure 5As shown, the sliding assembly 32 further includes at least one second pulley 323, and the bottom of the first mounting seat 321 is provided with at least one notch 3211; at least one second pulley 323 is correspondingly arranged in at least one notch 3211, and at least one second pulley 323 is connected to the first mounting seat 321; wherein the notch 3211 is provided to provide a limited installation space and movement trajectory for the second pulley 323: at least one second pulley 323 is arranged in the transverse direction, and at least two first pulleys 322 are respectively arranged in the longitudinal direction; At least one second pulley 323 cooperates with the side of the slide rail 31 to prevent the carriage 2 from shifting along the width direction of the frame 1. At least one second pulley 323 is closely attached to the side of the slide rail 31. When the carriage 2 slides, if it is subjected to a lateral force (such as a shift in the center of gravity of the carriage 2), at least one second pulley 323 can form a symmetrical support. Through the rolling contact between the second pulley 323 and the side of the slide rail 31, the lateral force is converted into rolling friction of the second pulley 323, thereby offsetting the tendency of the carriage 2 to shift along the width direction of the frame 1 and ensuring stable sliding operation of the carriage 2. It should be noted that in this embodiment, the second pulley 323 is arranged in the transverse direction, where the transverse direction is the length direction of the frame 1, and the first pulley 322 is arranged in the longitudinal direction, which is the height direction of the frame 1. It should be noted that in this embodiment, the number of second pulleys 323 is not limited and can be set according to actual conditions. In this embodiment, each sliding assembly 32 has two second pulleys 323, one on each of the front and rear sides.

[0086] In this embodiment, each sliding assembly 32 is equipped with a first pulley 322 and a second pulley 323. The first pulley 322 and the second pulley 323 cooperate to provide guidance for the sliding of the carriage 2. Multiple sliding assemblies 32 act as multiple guide points, enabling more precise control of the sliding direction of the carriage 2 and ensuring smooth movement of the carriage 2 along the slide rails 31. When removing the carriage 2 from the frame 1 for maintenance, precise sliding can keep the carriage 2 accurately positioned, facilitating maintenance operations and improving the efficiency and safety of maintenance work.

[0087] In the above embodiment, the first pulley 322 and the second pulley 323 slide on the slide rail 31 to drive the carriage 2 to slide along the length direction of the frame 1. In other embodiments, the slide rail 31 can also slide on the slide groove 33 to drive the carriage 2 to slide along the length direction of the frame 1. Specifically, Figure 7 and Figure 8As shown, the first sliding mechanism 3 includes two slide grooves 33 and two movable slide rails 34, the two slide grooves 33 are respectively arranged on the left and right sides in the width direction of the frame 1, the two slide grooves 33 are arranged opposite to each other at intervals, and the two slide grooves 33 are respectively fixedly connected to the frame 1 by welding; the two movable slide rails 34 are respectively arranged on the left and right sides in the width direction of the bottom of the carriage 2, the two movable slide rails 34 are arranged opposite to each other at intervals, and the two movable slide rails 34 are respectively fixedly connected to the carriage 2 by welding, the two movable slide rails 34 cooperate with the two slide grooves 33 to drive the carriage 2 to slide back and forth along the length direction of the frame 1, and the movable slide rails 34 slide on the slide grooves 33 to drive the carriage 2 to slide along the length direction of the frame 1.

[0088] Further, such as Figure 7 and Figure 8 As shown, the first sliding mechanism 3 also includes at least two movable pulleys 35, at least two of which are respectively arranged on the left and right sides of the movable rail 34, and at least two of which are symmetrically arranged to improve the sliding stability of the carriage 2. At least two of the movable pulleys 35 are respectively connected to the movable rail 34. By providing at least two movable pulleys 35, the friction between the movable rail 34 and the slide groove 33 is reduced, thereby ensuring the stability and smoothness of the sliding of the carriage 2. It should be noted that in this embodiment, the number of movable pulleys 35 is not limited and can be set according to actual conditions. In this embodiment, there are sixteen movable pulleys 35, eight on each side.

[0089] Optionally, in some embodiments, Figure 1 As shown, the rescue vehicle further includes a driving mechanism 7, which is provided on the frame 1 and connected to the carriage 2. The driving mechanism 7 is used to drive the carriage 2 to slide back and forth along the length direction of the frame 1. Specifically, in this embodiment, the driving mechanism 7 is a driving cylinder, which provides driving force through the driving cylinder to drive the carriage 2 to slide outward. The carriage 2 slides on the slide rail 31 through the first pulley 322 and the second pulley 323 to drive the carriage 2 to slide along the length direction of the frame 1. By providing the driving mechanism 7, time and labor are saved, work efficiency is improved, and the stability and accuracy of the sliding of the carriage 2 are improved. It should be noted that in other embodiments, the driving cylinder can also be replaced by a pneumatic cylinder or an electric cylinder.

[0090] Optionally, in some embodiments, Figure 2 and Figure 3As shown, the rescue vehicle also includes a lifting mechanism 4 and a second sliding mechanism 5. The lifting mechanism 4 is arranged on the inner wall of the car body 2; or in other embodiments, the lifting mechanism 4 can also be arranged on the outer wall of the car body 2. The lifting mechanism 4 is a mechanism for achieving the lifting and lowering of the second sliding mechanism 5. The lifting mechanism 4 is connected to the car body 2, and the second sliding mechanism 5 is arranged at the bottom of the lifting mechanism 4. The second sliding mechanism 5 is connected to the lifting mechanism 4. The second sliding mechanism 5 is used to drive the car body 2 to slide back and forth. The second sliding mechanism 5 is a mechanism for driving the car body 2 to slide on the ground when the car body 2 moves outward a certain distance. The lifting mechanism 4 is used to lower the second sliding mechanism 5 to drive the second sliding mechanism 5 to the ground, that is, to support the car body 2 after it moves out of the frame 1, preventing the rear end of the car body 2 from sagging and causing the car body 2 to deform. Then, as the car body 2 moves outward, the second sliding mechanism 5 can slide on the ground to ensure the stability and smoothness of the outward sliding of the car body 2. After the carriage 2 is retracted and moved inward to a certain distance, the lifting mechanism 4 is used to lift the second sliding mechanism 5 to drive the second sliding mechanism 5 to rise into the carriage 2.

[0091] Specifically, when the rescue equipment in the carriage 2 needs to be maintained, a certain force is applied outward in the length direction of the carriage 2 to remove the bolts between the carriage 2 and the frame 1. The carriage 2 can slide outward along the length direction of the frame 1 through the first sliding mechanism 3. After the carriage 2 slides out a certain distance, the second sliding mechanism 5 is lowered by the lifting mechanism 4 to drive the second sliding mechanism 5 to descend to the ground, which can support the carriage 2 moved out of the frame 1 and prevent the rear end of the carriage 2 from sagging, causing the carriage 2 to deform. Then, while the carriage 2 moves outward, the second sliding mechanism 5 can slide on the ground to ensure the stability and smoothness of the outward sliding of the carriage 2. After the carriage 2 is retracted and moved inward to a certain distance, the second sliding mechanism 5 is raised by the lifting mechanism 4 to drive the second sliding mechanism 5 to rise into the carriage 2.

[0092] Optionally, in some embodiments, Figure 2 and Figure 3 As shown, there are two lifting mechanisms 4 and two second sliding mechanisms 5. The two lifting mechanisms 4 are respectively arranged on the left and right sides of the rear end of the carriage 2 to prevent the rear end of the carriage 2 from sagging. The two second sliding mechanisms 5 are respectively arranged at the bottom of the two lifting mechanisms 4. The provision of two lifting mechanisms 4 and two second sliding mechanisms 5 ensures uniform load bearing, improves load-bearing capacity, and enhances stability.

[0093] Optionally, in some embodiments, Figure 2 and Figure 3As shown, the lifting mechanism 4 includes a telescopic assembly 41 and a lifting drive component 42. The telescopic assembly 41 is disposed in the carriage 2, and the second sliding mechanism 5 is disposed at the protruding end of the telescopic assembly 41. It should be noted that the protruding end here is the telescopic rod 412 of the telescopic assembly 41. The lifting drive component 42 is connected to the telescopic assembly 41 and is used to drive the telescopic assembly 41 to extend downward or retract upward. When the telescopic assembly 41 is driven downward or retracted upward by the lifting drive component 42, the second sliding mechanism 5 at the bottom of the telescopic assembly 41 is simultaneously driven downward or retracted, which is simple to operate, saves time and effort, and improves work efficiency.

[0094] Optionally, in some embodiments, Figure 2 and Figure 3 As shown, the telescopic assembly 41 includes a fixed slot 411 and a telescopic rod 412. The fixed slot 411 is fixedly disposed on the inner wall of the carriage 2. The telescopic rod 412 is nested within the fixed slot 411 and slidably connected to the fixed slot 411, allowing the telescopic rod 412 to slide within the fixed slot 411. The lifting drive component 42 is a lifting cylinder, one end of which is fixedly connected to the top of the carriage 2. Alternatively, in other embodiments, one end of the lifting cylinder is fixedly connected to the outer wall of the fixed slot 411, and the other end is fixedly connected to the end of the telescopic rod 412. The lifting cylinder drives the telescopic rod 412 downward or upward, simultaneously driving the second sliding mechanism 5 at the bottom of the telescopic rod 412 downward or upward. This simplifies operation, saves time and effort, and improves work efficiency. In other embodiments, the lifting cylinder can be replaced with a pneumatic cylinder or an electric cylinder.

[0095] Specifically, in this embodiment, Figure 2 and Figure 3 As shown, the telescopic assembly 41 also includes at least two reinforcing rods 413. There are two telescopic rods 412, and the two telescopic rods 412 are respectively nested in the fixed groove 411. The two telescopic rods 412 are respectively slidably connected to the fixed groove 411. The provision of two telescopic rods 412 further supports the car body 2, ensuring the stability and smoothness of the outward sliding of the car body 2. At least two reinforcing rods 413 are respectively spaced between the two telescopic rods 412, and at least two reinforcing rods 413 are respectively connected to the two telescopic rods 412. The provision of at least two reinforcing rods 413 increases the rigidity between the two telescopic rods 412, further improving the sliding stability of the car body 2. It should be noted that in this embodiment, the number of reinforcing rods 413 is not limited and can be set according to actual conditions. In this embodiment, there are four reinforcing rods 413.

[0096] Optionally, in some embodiments, Figure 2 and Figure 3 As shown, the second sliding mechanism 5 includes a second mounting base 51 and at least one third pulley 52. The second mounting base 51 is fixedly connected to the lifting mechanism 4, and at least one third pulley 52 is mounted on the second mounting base 51. By providing at least one third pulley 52, the third pulley 52 can slide on the ground, reducing the force applied by the operator to the carriage 2, simplifying the operation, and facilitating the sliding of the carriage 2. It should be noted that in this embodiment, the number of third pulleys 52 is not limited and can be set according to actual conditions. In this embodiment, each second sliding mechanism 5 has two third pulleys 52.

[0097] Optionally, in some embodiments, Figure 6 As shown, the top outer wall of the carriage 2 is provided with a plurality of lifting rings 21, each of which is fixedly connected to the carriage 2. In this embodiment, there are six lifting rings 21, four of which are located on the outer walls around the top of the carriage 2, and two on the outer wall in the middle of the top of the carriage 2. The multiple lifting rings 21 prevent the carriage 2 from sliding on the frame 1 due to unexpected circumstances. In this case, the carriage 2 can be separated from the workshop by lifting to perform maintenance on the emergency equipment.

[0098] Optionally, in some embodiments, Figure 1 and Figure 2 As shown, the rescue vehicle also includes a cab and a fixed compartment 6. The fixed compartment 6 is fixedly arranged on the frame 1. The fixed compartment 6 is located at the front end of the compartment 2, that is, the fixed compartment 6 is arranged between the cab and the compartment 2, wherein the fixed compartment 6 is used to place rescue equipment.

[0099] Specifically, in this embodiment, Figures 1 to 6As shown, when the rescue equipment in the carriage 2 needs to be maintained, the bolts between the carriage 2 and the frame 1 are removed, and a certain force is applied outward in the length direction of the carriage 2 so that the first pulley 322 and the second pulley 323 can slide on the slide rail 31. At this time, the carriage 2 can slide outward along the length direction of the frame 1. After the carriage 2 slides out for a distance, the telescopic rod 412 is driven down by the lifting cylinder to drive the third pulley 52 on the telescopic rod 412 to drop to the ground, which can support the carriage 2 moved out of the frame 1 and prevent the carriage 2 from sliding out. 2, causing the car body 2 to sag, causing the car body 2 to deform. Then, while the car body 2 moves outward, the third pulley 52 can slide on the ground to ensure the stability and smoothness of the outward sliding of the car body 2. This can also reduce the force applied by the operator to the car body 2, reduce the difficulty of operation, and facilitate the outward sliding of the car body 2, thereby fully exposing the interior space of the car body 2. This allows for quick inspection and maintenance of the rescue equipment inside the car body 2 and on the frame 1. The operation is simple, effectively shortens maintenance time, improves work efficiency, and does not require vertical space. Maintenance can be carried out in a general factory building. At the same time, it avoids component damage that may be caused by overall lifting, reducing maintenance costs.
