The sequence of mechanical actions of the entire device:
When the vehicle body 10 needs to pass through a dangerous road section, the vehicle owner needs to install the bottom plate 19 and the shell 15 under the chassis of the vehicle body 10 in advance. The driven gear 21 does not need to be installed temporarily. When the vehicle body 10 passes through the mud and is stuck in the mud, it will The movable gear 21 is fixedly installed on the upper end of the lifting threaded rod 25, the air pump 40 is activated to inject gas into the auxiliary airbag 14, the auxiliary airbag 14 expands to the left and right sides and pushes the baffle 38 to rotate around the hinge 39, and the auxiliary airbag 14 expands to the airbag cavity On the outside of 37, the expanded auxiliary airbag 14 can increase the contact area with the quagmire to prevent the body 10 from continuing to sink. The tire 35 will slip after the body 10 is trapped in the quagmire. The slippery tire 35 drives the bevel gear shaft 58 to rotate through the drive pulley 59. The gear shaft 58 drives the drive bevel gear 23 to rotate, the drive bevel gear 23 drives the driven bevel gear 24 and the rotating shaft 28 to rotate, the drive gear 22 drives the driven gear 21 and the lifting threaded rod 25 to rotate, the lifting threaded rod 25 rotates and drives the bottom plate 19 upward When moving, the bottom plate 19 supports the body 10 to move upwards. When it reaches the specified height, the owner stops stepping on the accelerator to stop the tire 35 from rotating, rotates the fixing screw 33 and removes it. The tension slider 34 is pulled by the tension spring 16 to drive the bottom plate 19 along the tension The chute 17 slides to the left, and the bottom plate 19 drives the body 10 to slide to the left. After the pull slider 34 slides to the left for a certain distance, the top rod 20 begins to be inserted into the through hole 49 and pushes the rotating rod 50 to rotate counterclockwise to a certain angle, and the rotating rod 50 is counterclockwise. After the hour hand rotates, the clamping block 45 will be pulled out of the clamping slot 44, the limit block 60 is released from the fixed state, and is pushed by the tension spring 16 to slide out the tension chute 17 to the left, the bottom plate 19 and the body 10 are also inertial Under the action of, slide the pulling chute 17 to the left, and push the car body 10 out of the quagmire through this section of sliding. After the car body 10 leaves the quagmire, the power motor 31 starts to drive the reel 26 and the reel 29 to rotate through the pulley 30. 29 Rotate the winding rope 32 to pull out the shell 15 from the quagmire to complete the relief. When there are large rocks or trees nearby, the wire rope 36 can also be used to assist the relief, and the sliding rail 13 starts to drive the traction coil The wheel 11 and the reel gear 12 slide to the right. The user pulls the wire rope 36 and binds the wire rope 36 to a rock or tree, and then the traction slide 13 starts to drive the traction reel 11 to slide to the left to provide the body 10 With a certain auxiliary pulling force, after the wire rope 36 is used up, the traction slide 13 starts to drive the traction reel 11 to slide to the left, the reel gear 12 meshes with the reel power gear 53, and the rotating shaft 56 is rotated through the power bevel gear 57 and The transmission of the winding bevel gear 52 and the winding power gear 53 drives the winding gear 12 and the traction reel 11 to rotate, and the traction reel 11 rotates to rewind the steel wire rope 36 and store it in the traction chamber 18.
