Description

Technical Field

[0001] The present invention relates to the technical field of emergency rescue vehicles, and in particular to a multifunctional emergency rescue vehicle and a use method thereof. Background Art

[0002] A multifunctional emergency rescue vehicle is a special vehicle designed to respond to various emergency situations. It is equipped with a variety of rescue equipment and tools, and can respond quickly and carry out efficient rescue operations on site. The multifunctional emergency rescue vehicle is characterized by its high flexibility and versatility. It can be equipped with corresponding equipment according to different rescue needs, such as fire-fighting equipment, life-saving equipment, demolition tools, etc. It is suitable for fire fighting, emergency rescue, medical rescue and other tasks, so that it can play a role in different rescue scenarios.

[0003] According to a smart multifunctional emergency vehicle and its use method with patent publication number CN114490857A, it relates to the technical field of road rescue vehicles, specifically a vehicle body and a smart terminal. The interior of the vehicle body is provided with a gas supply and storage system, a device placement system and an emergency equipment system from left to right in sequence. The top of the cab and the two sides and back of the vehicle body are provided with a warning system. The back of the vehicle body and the two sides of the vehicle body are provided with a lighting system. The smart terminal is provided inside the cab of the vehicle body. The patent achieves the effect of transmitting real-time data on the scene through the above structure, and can accurately arrange rescue tools based on the real-time situation on the scene, but there are still some limitations. Specifically, the above multifunctional emergency vehicle lacks the function of removing obstacles on the scene, which means that when encountering obstacles or needing to clear a life channel, the rescue vehicle may not be able to directly reach the rescue site, thereby delaying the rescue opportunity. In addition, some more advanced emergency rescue vehicles will use a crane arm to enhance their rescue capabilities in response to such situations. The crane arm can lift and remove heavy obstacles. However, due to the structural limitations of the crane arm itself, its movement trajectory and operation direction are relatively single, causing it to appear bulky in some areas that require multiple actions to coordinate and handle. The overall flexibility is lacking and the adaptability is insufficient, which in turn has a certain impact on the emergency rescue process on the scene.

[0004] Therefore, in view of the above situation, it is urgent to propose a multifunctional emergency rescue vehicle and a method of using the vehicle that can flexibly handle obstacles at the rescue site. Summary of the invention

Push plates that contact the adjacent contact blocks are provided on the two insertion rods, and an elastic member is provided between the push plate and the mounting block on the same side.

[0009] Preferably, a water spray mechanism is also included, which includes a connecting block, a spray gun, a water pipe and a water pump. Connecting blocks are provided on both sides of the movable seat, spray guns are plugged into the two connecting blocks, the rear ends of the two spray guns are connected to the water pipes, water pumps are installed on both sides of the interior of the vehicle body, and the water outlets of the two water pumps are respectively connected to the water pipes on the same side.

[0010] Preferably, it also includes a multi-stage elevator and an illuminating lamp. The multi-stage elevator is arranged in the vehicle body, and the illuminating lamp is arranged on the telescopic end of the multi-stage elevator.

[0011] Preferably, it also includes a protective shell, a winding wheel and a connecting shaft. The rear part of the vehicle body is provided with a protective shell located below the base. A winding wheel for winding a rope is rotatably arranged in the protective shell. A groove for extending the traction rope is provided on the front side wall of the winding wheel. A connecting shaft with a top end connected to the winding wheel is rotatably arranged on the vehicle body.

[0012] Preferably, it also includes a motor II, a small gear and a large gear. The large gear is arranged on the lower side of the connecting shaft. The motor II located inside the protective shell is installed on the vehicle body. The output shaft of the motor II is connected to a small gear meshing with the large gear.

[0013] Preferably, the inner side surfaces of the two clamping blocks are arranged in recesses, suitable for fitting to the surface of the obstacle to form a clamping clamp.

[0014] A method for using a multifunctional emergency rescue vehicle comprises the following steps: S1. In order to cope with emergency rescue situations, the vehicle needs to drive quickly to the rescue site. When encountering obstacles that hinder rescue at the scene, first move the rear of the vehicle to the obstacle clearance site, then take the rescue tools on the vehicle and take corresponding rescue measures, then start the mechanical arm I and the mechanical arm II, and control the mechanical arm I and the mechanical arm II to perform corresponding rotation operations, so as to adjust the angle to a certain extent according to the required clearing position, and adjust to a position close to the obstacle. At the same time, the hydraulic cylinder is started, and the telescopic operation of the telescopic end of the hydraulic cylinder is coordinated to push the connecting seat up and down, and then the motor I and the driving member are started together. The motor I drives the moving seat to rotate and adjust the angle position of the two clamping blocks on it. Then the driving member drives the crank to rotate, so that the crank drives the connecting rods at both ends to rotate, thereby driving the clamping block to clamp or loosen, and the obstacle can be grasped and cleared in cooperation with the operation of the clamping block, and the clamping block is flexibly used in combination with the above operations to effectively clear the obstacles that can be clamped and cleared; S2. During this process, the rotation of the moving seat will drive the contact blocks on both sides to operate synchronously, and then the contact blocks will contact the adjacent pushing plates, thereby pushing the connected plug rods to slide on the mounting blocks and pull them out from the corresponding rotating shaft and the rotating frame, so that the rotating frame is no longer restricted by the plug rods, and rotates on the rotating shaft under the influence of gravity. The rotating frame operates with a downward trend, driving the auxiliary wheels on it to operate synchronously and finally contact the ground, supporting and lifting the positions on both sides of the connecting seat. In this form, larger obstacles can be handled by cooperating with the clamping block. First, ensure that the clamping block clamps the obstacle or is placed under the large obstacle to prepare for lifting, and then start the electric screw to drive the rotating frame to move downward in the direction of the auxiliary wheel, apply a downward force to the middle of the connecting seat, and at the same time, the telescopic end of the hydraulic cylinder will push the connecting seat to lift it upward, so that the connecting seat will then rotate forward, and cooperate with the downward force applied to form a reaction force with the lifting force, thereby pushing the clamping block to form an explosive upward push, so that the large obstacle is removed and moved away from the rescue site; S3. When there are debris blocking the sight during the obstacle removal process, first connect the water pump to the external water source, then use the water pump to flow water to the spray gun through the water pipe, and then spray it out from the spray gun to flush the impurities that block the sight during the obstacle removal, so as to maintain the required clear viewing angle. If the light is dim, start the lighting lamp for illumination, and then change the height of the lighting lamp in conjunction with the lifting operation of the multi-stage elevator, so as to adjust the lighting height; S4. The situations in rescue are ever-changing. When a rope is needed, just hold the exposed end of the rope and use the motor II to drive the small gear to rotate, so that the small gear meshes with the large gear, driving the winding wheel to rotate, thereby paying out the rope on it and allowing the rope to be used.

[0015] The present invention overcomes the shortcomings of the prior art and can achieve the following beneficial effects: 1. The present invention, through the setting of the obstacle removal mechanism, is driven by the hydraulic cylinder to adjust the angle of the clamping block used for clamping obstacles in the up and down directions; then the motor I is used to drive to achieve the rotation angle adjustment of the clamping block; finally, the crank is driven by the driving member, and then the connecting rod is pulled to push the two clamping blocks to complete the clamping and loosening actions, so that the obstacles that hinder the rescue can be effectively and flexibly cleared, ensuring that the obstacles are cleared more thoroughly, and providing valuable conditions for the rescue work.

[0016] 2. The present invention uses an auxiliary mechanism to push the rotating frame downward using an electric screw, thereby forming a reaction force with the raised connecting seat to assist the clamping block in pushing the large obstacle, thereby enhancing the pushing effect.

[0017] 3. The present invention, through the setting of the synchronization mechanism, utilizes the contact block to rotate and contact with the push plate, so as to push the insertion rod to separate from the rotating shaft and the rotating frame, so that the rotating frame can rotate freely and fall, thereby pushing the auxiliary wheel to be lowered, ensuring the continuity of operation and realizing the integration of operation.

[0018] 4. The present invention uses a water spray mechanism to spray water from a spray gun to flush away debris that obstructs the rescue line of sight, thereby clearing obstacles to the line of sight and ensuring clear vision during the rescue process.

[0019] 5. The present invention drives the small gear to rotate through the motor II, which meshes with the large gear to drive the winding wheel to rotate, thereby realizing automatic release or reeling of the rope, which not only ensures the diversity of rescue tools, but also realizes the automation of operation.

The crank 37 is driven to rotate by the driving part 36, thereby driving the connecting rods 38 at both ends to operate synchronously, and then the two clamping blocks 35 connected respectively are pulled, so as to push the clamping blocks 35 to clamp or release each other, thereby combining the above-mentioned position and angle adjustment operations to cooperate in completing the clearance of obstacles, and providing precious rescue time and channels for the rescue process.

[0035] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, an auxiliary mechanism 4 is also included. The auxiliary mechanism 4 is mainly used to cooperate with the clamping block 35 to perform a jacking-up removal process on large obstacles, wherein the auxiliary mechanism 4 includes a rotating shaft 41, a rotating frame 42, an electric screw 43 and an auxiliary wheel 44. The left and right sides of the connecting seat 32 are provided with a rotating shaft 41, and the rotating frame 42 is provided on the rotating shaft 41. The rotating frame 42 is in a folded state parallel to the connecting seat 32 in the initial state. An electric screw 43 is fixedly installed on the top of the rotating frame 42. The screw of the electric screw 43 is arranged downward and passes through the rotating frame 42 on the same side. The screw of the electric screw 43 is threaded. Auxiliary wheels 44 are provided, and the rotating frame 42 can be lowered together with the auxiliary wheels 44 to provide support for both sides of the connecting seat 32. Then, the electric screw rod 43 can drive the rotating frame 42 to rise or fall relative to the auxiliary wheels 44, thereby pushing the connecting seat 32 to operate synchronously. In this way, a reaction force can be formed in conjunction with the force of the connecting seat 32 being driven by the hydraulic cylinder 31 to tilt forward or backward, thereby helping to stabilize the position of the connecting seat 32 and its upper components, reduce shaking and improve the accuracy of the operation. In this way, the clamping or pushing assistance of the clamping block 35 can be used to more stably remove large obstacles.

The operation is coherent, the operation runs smoothly, and the operation is presented in an integrated manner, which brings a more convenient use effect for rescue work.

[0037] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 8 and Fig. 9 As shown, a water spray mechanism 6 is also included, and the water spray mechanism 6 also includes a connecting block 61, a spray gun 62, a water pipe 63 and a water pump 64.

The water outlets of the two water pumps 64 are respectively connected to the water pipe 63 on the same side. The water pump 64 is connected to an external water source to transport water to the spray gun 62. The water column ejected by the spray gun 62 is used to flush the impurities at the rescue site, so that the rescue sight and visibility can be maintained.

[0038] like Figure 1 and Fig. 9 As shown, it also includes a multi-stage lift 7 and an illumination lamp 71. The multi-stage lift 7 is arranged in the vehicle body 1, and the illumination lamp 71 is arranged on the telescopic end of the multi-stage lift 7 to achieve the lighting effect of lifting.

[0039] like Figure 1 , Fig.10 and Fig.11 As shown, it also includes a protective shell 8, a winding wheel 81 and a connecting shaft 85. The rear part of the vehicle body 1 is provided with a protective shell 8 located below the base 2. A winding wheel 81 for winding a rope is rotatably arranged in the protective shell 8. A groove for extending the traction rope is opened on the front side wall of the winding wheel 81, and a connecting shaft 85 connected to the winding wheel 81 at the top is rotatably arranged on the vehicle body 1.

[0040] like Fig.11 As shown, it also includes a motor II 82, a small gear 83 and a large gear 84. The large gear 84 is arranged on the lower side of the connecting shaft 85. The motor II 82 located inside the protective shell 8 is installed on the vehicle body 1. The output shaft of the motor II 82 is connected with a small gear 83 meshing with the large gear 84. The above-mentioned automated rope retracting and releasing operation is realized, making the use of the rope more convenient during the rescue process.

[0041] Based on the above multifunctional emergency rescue vehicle, a method for using the multifunctional emergency rescue vehicle includes the following steps: S1. In order to cope with emergency rescue situations, the vehicle body 1 needs to drive quickly to the rescue site. When encountering obstacles that hinder rescue at the site, the vehicle body 1 first moves to the obstacle clearance position, then takes the rescue tools on the vehicle body 1 and takes corresponding rescue measures, then starts the mechanical arm I 21 and the mechanical arm II 22, controls the mechanical arm I 21 and the mechanical arm II 22 to perform corresponding rotation operations, and adjusts the angle to a certain range according to the required clearance position, and adjusts to a position close to the obstacle. At the same time, the hydraulic cylinder 31 is started, and the telescopic end of the hydraulic cylinder 31 is coordinated. The telescopic operation pushes the connecting seat 32 up and down, and then the motor I 33 and the driving member 36 are started at the same time. The motor I 33 drives the moving seat 34 to rotate, and the angle position of the two clamping blocks 35 thereon is adjusted. Then the driving member 36 drives the crank 37 to rotate, so that the crank 37 drives the connecting rods 38 at both ends to rotate, thereby driving the clamping block 35 to clamp or loosen, and the operation of the clamping block 35 can be used to grab and remove obstacles. In combination with the above operations, the clamping block 35 can be flexibly used to effectively remove obstacles that can be clamped and cleaned. S2. During this process, the rotation of the moving seat 34 will drive the contact blocks 51 on both sides to operate synchronously, and then the contact blocks 51 will contact the adjacent pushing plates 54, thereby pushing the connected plug rods 53 to slide on the mounting blocks 52 and be pulled out from the corresponding rotating shafts 41 and the rotating frame 42, so that the rotating frame 42 is no longer restricted by the plug rods 53, and rotates on the rotating shaft 41 under the influence of gravity. The rotating frame 42 operates with a downward trend, driving the auxiliary wheels 44 thereon to operate synchronously and finally contact the ground, supporting and lifting the positions on both sides of the connecting seat 32. In this form, it can be lifted by the clamping The block 35 cooperates to handle larger obstacles. First, ensure that the clamping block 35 clamps the obstacle or is placed under the large obstacle to prepare for lifting. Then start the electric screw 43 to drive the rotating frame 42 to move downward in the direction of the auxiliary wheel 44, and apply a downward force to the middle of the connecting seat 32. At the same time, the telescopic end of the hydraulic cylinder 31 will push the connecting seat 32 to lift it upward, so that the connecting seat 32 will tilt forward and rotate. In combination with the downward force applied, a reaction force is formed with the lifting force, thereby pushing the clamping block 35 to form an explosive upward push, so that the large obstacle is removed and moved away from the rescue site; S3. When there are debris blocking the sight during the obstacle removal process, the water pump 64 is first connected to the external water source, and then the water flow is coordinated with the water pipe 63 to flow to the spray gun 62 through the water pump 64, and then sprayed out by the spray gun 62 to flush the impurities that block the sight during the obstacle removal, so as to maintain the required clear viewing angle. If the light is dim, the lighting lamp 71 is started for lighting, and then the height of the lighting lamp 71 is changed in coordination with the lifting operation of the multi-stage lift 7, so as to adjust the lighting height; S4. The situations in rescue are changeable. When a rope is needed, the exposed end of the rope is directly grasped, and the motor II 82 drives the small gear 83 to rotate, so that the small gear 83 is engaged with the large gear 84, and the winding wheel 81 is driven to rotate, thereby releasing the rope thereon and allowing the rope to be used.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.

9. A method for using the multifunctional emergency rescue vehicle according to any one of claims 1 to 8, characterized in that: Included are: S1. In order to cope with emergency rescue situations, the vehicle body (1) needs to drive quickly to the rescue site. When an obstacle is encountered at the site that hinders the rescue, the vehicle body (1) is first moved to the obstacle clearance position, and then the rescue tools on the vehicle body (1) are taken to take corresponding rescue measures. Then, the mechanical arm I (21) and the mechanical arm II (22) are started, and the mechanical arm I (21) and the mechanical arm II (22) are controlled to perform corresponding rotation operations, so as to adjust the angle to a certain range according to the required clearance position, and adjust to a position close to the obstacle. At the same time, the hydraulic cylinder (31) is started, and the telescopic end of the hydraulic cylinder (31) is telescopically operated. The connecting seat (32) is pushed up and down, and then the motor I (33) and the driving member (36) are started at the same time. The motor I (33) drives the moving seat (34) to rotate, and the angle position of the two clamping blocks (35) thereon is adjusted. Then, the driving member (36) drives the crank (37) to rotate, so that the crank (37) drives the connecting rods (38) at both ends to rotate, thereby driving the clamping blocks (35) to clamp or loosen, and the operation of the clamping blocks (35) can be used to grab and remove obstacles. In combination with the above operations, the clamping blocks (35) are flexibly used to effectively remove obstacles that can be clamped and cleaned; S2. During this process, the rotation of the moving seat (34) drives the contact blocks (51) on both sides to operate synchronously, and then the contact blocks (51) contact the adjacent push plates (54), thereby pushing the connected insertion rods (53) to slide on the mounting blocks (52) and be pulled out from the corresponding rotating shafts (41) and the rotating frame (42), so that the rotating frame (42) is no longer restricted by the insertion rods (53) and rotates on the rotating shafts (41) under the influence of gravity. The rotating frame (42) operates in a downward trend, driving the auxiliary wheels (44) thereon to operate synchronously and finally contact the ground, supporting and lifting the positions on both sides of the connecting seat (32). In this state, the rotating frame (42) can be lifted. The larger obstacle is handled by cooperating with the clamping block (35). First, ensure that the clamping block (35) clamps the obstacle or is placed under the large obstacle to prepare for lifting. Then, the electric screw (43) is started to drive the rotating frame (42) to move downward in the direction of the auxiliary wheel (44), and a downward force is applied to the middle part of the connecting seat (32). At the same time, the telescopic end of the hydraulic cylinder (31) pushes the connecting seat (32) to lift it upward, so that the connecting seat (32) tilts forward and rotates forward, and cooperates with the downward force to form a reaction force with the lifting force, thereby pushing the clamping block (35) to form an explosive upward push, so that the large obstacle is removed and moved away from the rescue site; S3. When debris obstructs the sight during the obstacle removal process, the water pump (64) is first connected to an external water source, and then the water flow is coordinated with the water pipe (63) to flow to the spray gun (62) through the water pump (64), and then sprayed out by the spray gun (62) to flush out the impurities that obstruct the sight during the obstacle removal, thereby maintaining the required clear viewing angle. If the light is dim, the lighting lamp (71) is started for lighting, and then the height of the lighting lamp (71) is changed in coordination with the lifting operation of the multi-stage lift (7), thereby adjusting the height of the lighting; S4. The situations in rescue vary. When a rope is needed, the user directly holds the exposed end of the rope and drives the small gear (83) to rotate with the motor II (82), so that the small gear (83) meshes with the large gear (84), driving the winding wheel (81) to rotate, thereby releasing the rope thereon and allowing the rope to be used.
