[0016] S1, in order to cope with the sudden rescue situation, the vehicle body needs to quickly drive to the rescue site, when encountering obstacles in the field, first move the vehicle body to the obstacle removing place, then take the rescue tools on the vehicle body to take corresponding rescue measures, then start the mechanical arm I and the mechanical arm II, control the mechanical arm I and the mechanical arm II to rotate and operate, adjust the angle to the required removal position, adjust to the position close to the obstacle, at the same time, start the hydraulic cylinder, cooperate with the extension and retraction of the hydraulic cylinder to push the connecting seat up and down, then start the motor I and the driving part, the motor I drives the moving seat to rotate, adjusts the angle position of the two clamping blocks on it, and then the driving part drives the crank to rotate, so that the crank drives the connecting rod at both ends to rotate, thereby driving the clamping block to clamp or loosen, which can cooperate with the operation of the clamping block to grasp and remove the obstacle, and the clamping block can be flexibly used in combination with the above operation to effectively remove the obstacles that can be grasped and cleaned;

[0017] S2, in this process, the rotation of the moving seat will drive the two side contact blocks to operate synchronously, then the contact blocks contact with the adjacent push plate, so that the connected inserting rod slides on the mounting block and is pulled out from the inside of the rotating shaft and the rotating frame, so that the rotating frame is no longer limited by the inserting rod and rotates on the rotating shaft under the influence of gravity, the rotating frame operates in the downward trend, drives the auxiliary wheel on it to operate synchronously and finally contacts with the ground, supports and lifts up the two sides of the connecting seat, in this form, the larger obstacle can be processed by cooperating with the clamping block, first, ensure that the clamping block clamps the obstacle or is placed below the large obstacle to prepare for lifting, then start the electric screw rod to drive the rotating frame to move downward towards the auxiliary wheel, apply downward force to the middle part of the connecting seat, at the same time, the extension and retraction of the hydraulic cylinder will push the connecting seat to lift up, so that the connecting seat tilts forward, cooperate with the downward force and the lifting force to form a counter force, thereby pushing the clamping block to form an explosive upward movement, so that the large obstacle is removed and moved away from the rescue place;

[0018] S3, when encountering sundry obstacles in the process of removing obstacles, first connect the water pump with the external water source, then pass the water flow through the water delivery pipe to the spray gun by the water pump, and then spray out by the spray gun to flush the sundry obstacles that obstruct the line of sight during the removal of obstacles, so as to maintain the required clear view, if the light is dim, start the lighting lamp to illuminate, and change the height of the lighting lamp by cooperating with the lifting operation of the multi-stage elevator, so as to adjust the height of the illumination.

[0021] 1, by the setting of the obstacle removing mechanism, driven by the hydraulic cylinder, the angle of the clamping block for clamping the obstacle in the up-down direction can be adjusted, then the motor I is used to drive to realize the angle adjustment of the clamping block, finally the driving part drives the crank, and then pulls the connecting rod 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 cleaned, and the obstacles can be completely removed, which provides valuable conditions for the rescue work.

[0022] 2, by the setting of the auxiliary mechanism, the rotary frame is pushed down by the electric screw rod to form a reaction force with the jacking connecting seat, which assists the clamping block to jack up the large obstacle, so as to enhance the pushing effect.

[0023] 3, by the setting of the synchronous mechanism, the contact block rotates and contacts the pushing plate to make the plug rod separate from the rotating shaft and the rotary frame, so that the rotary frame can freely rotate and fall down, thereby pushing down the auxiliary wheel to ensure the continuity of operation and realize the integration of operation.

6. The multifunctional emergency rescue vehicle according to claim 5, characterized in that: The inner side surfaces of the two clamping blocks (35) are arranged in recessed shapes, suitable for fitting onto the surface of an obstacle to form a clamping clamp.

7. A method for using the multifunctional emergency rescue vehicle according to claim 6, characterized in that: Includes: S1. In order to cope with emergency rescue situations, the vehicle body (1) needs to move quickly to the rescue site. When encountering obstacles that hinder rescue at the scene, the vehicle body (1) is first moved to the obstacle clearance site, 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 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. Push the connecting seat (32) up and down, then start the motor I (33) and the driving member (36) at the same time, the motor I (33) drives the moving seat (34) to rotate, and adjusts the angle position of the two clamping blocks (35) thereon, and 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, and the clamping blocks (35) can be flexibly used in combination with the above operations 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 pull out from the corresponding rotation 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 rotation shaft (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 form, the rotating frame (42) can be lifted. By cooperating with the clamping block (35) to handle larger obstacles, first ensure that the clamping block (35) clamps the obstacle or is placed under the large obstacle to prepare for jacking, then start the electric screw (43) to drive the rotating frame (42) to move downward in the direction of the auxiliary wheel (44), apply a downward force to the middle of the connecting seat (32), and at the same time, the telescopic end of the hydraulic cylinder (31) will push the connecting seat (32) to jack up, so that the connecting seat (32) will then rotate forward and form a reaction force with the jacking force in conjunction with the applied downward force, thereby pushing the clamping block (35) to form an explosive upward jacking, so that the large obstacle is removed and moved away from the rescue area; S3. When encountering debris that blocks the sight during the obstacle removal process, first connect the water pump (64) to the external water source, then use the water pump (64) to circulate the water flow in conjunction with the water pipe (63) to the spray gun (62), and then spray it out from the spray gun (62) to flush out the impurities that block the sight during the obstacle removal, thereby maintaining the required visual angle clear. If the light is dim, the lighting lamp (71) is started for lighting, and then the height of the lighting lamp (71) is changed by the lifting operation of the multi-stage elevator (7), thereby adjusting the lighting height; S4. The situations in rescue are ever-changing. When a situation requires the use of a rope, the user directly grasps 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) engages with the large gear (84), driving the winding wheel (81) to rotate, thereby releasing the rope on it and allowing the rope to be used.
