Detailed Implementation

[0018] like Figure 1 and Figure 2 As shown, the adjustable damping shock absorber support for the gas generator set includes a base plate 1. The gas generator set is mounted on the upper surface of the base plate 1. Damping shock absorber structures 2 are located at the four corners of the base plate 1. The damping shock absorber structure 2 includes a piston cylinder 3 and a damping circuit. The piston cylinder 3 is located at the four corners of the base plate 1. A hydraulic cylinder 9 is connected above the piston cylinder 3 and is located inside the base plate 1. A piston rod 4 is located inside the piston cylinder 3. The piston cylinder 3 and the piston rod 4 are connected by a damping connection. The lower end of the piston rod 4 is arc-shaped. A buffer block 6 is also provided below the piston cylinder 3. The buffer block 6 is hollow. The lower end of the piston rod 4 is located inside the hollow buffer block 6. A groove is also provided on the lower surface of the buffer block 6. An inner column 21 is provided on the inner wall of the groove. The inner column 21 can rotate within the groove on the lower surface of the buffer block 6. A contact body 7 is also fixed to the surface of the inner column 21. The upper surface of the contact body 7 is arc-shaped, and a rubber pad is embedded on the lower surface of the contact body 7.

[0019] A damping spring 5 is also provided between the piston cylinder 3 and the buffer block 6. The damping spring 5 is located on the outer surface of the piston rod 4. A cooperating rod 22 is fixedly connected to the surface of the piston cylinder 3. A lifting rheostat 8 is fixedly connected to the surface of the buffer block 6. The lower end of the cooperating rod 22 is connected to the middle contact of the lifting rheostat 8.

[0020] When the working ground where the gas generator set is parked is uneven, the contact body 7 can rotate around the inner column 21, and the lower surface of the piston rod 4 abuts against the upper surface of the adjacent contact body 7 to support the gas generator set above. Through the contact of the arc-shaped surfaces between the contact body 7 and the piston rod 4, and the rotation of the contact body 7 around the inner column 21, it can automatically adapt to uneven ground.

[0021] like Figure 3 As shown, the damping circuit includes chip U1, which is an integrated operational amplifier. The model of chip U1 is LM324N. Pin 3 of chip U1 is connected to one end of resistor R1 and one end of a step-up rheostat. The other end of resistor R1 is connected to a +24V power supply. The other end of the step-up rheostat is connected to pin 2 of chip U1 and one end of resistor R2. The other end of resistor R2 is connected to ground.

[0022] Pin 2 of chip U1 is connected to one end of resistor R3. The other end of resistor R3 is connected to pin 1 of chip U1 and one end of resistor R4. Pin 4 of chip U1 is connected to ground. Pin 8 of chip U1 is connected to a +10V power supply. The other end of resistor R4 is connected to one end of resistor R7 and pin 3 of chip U2. The other end of resistor R7 is connected to ground. Chip U2 is an integrated operational amplifier, model LM358P. Pin 2 of chip U2 is connected to one end of resistor R5 and one end of resistor R6. The other end of resistor R5 is connected to a +12V power supply. The other end of resistor R6 is connected to ground. Pin 4 of chip U2 is connected to ground. Pin 8 of chip U2 is connected to... There is a +12V power supply. Pin 1 of chip U2 is connected to pin 2 of chip U3 and one end of capacitor C1. Chip U3 is an integrated operational amplifier, model LM107. The other end of capacitor C1 is connected to pin 6 of chip U3 and one end of resistor R9. Pin 3 of chip U3 is connected to one end of resistor R8. The other end of resistor R8 is connected to ground. The other end of resistor R9 is connected to pin 1 of chip U4. Chip U4 is an optocoupler, model TD851. Pin 2 of chip U4 is connected to ground. Pin 3 of chip U4 is connected to a +48V power supply. Pin 4 of chip U4 is connected to voltage signal V1, which is the hydraulic cylinder start signal.

[0023] When the gas generator set on the upper surface of the base plate is working, causing significant vibration in one corner of the base plate, the distance between the piston cylinder and the damping block changes more, which in turn causes the sliding amplitude of the middle contact of the lifting rheostat to change more, resulting in a greater change in the resistance value between the lifting rheostats. Pins 2 and 3 of chip U1 collect the voltage change between the lifting rheostats and output it through pin 1 of chip U1. The voltage at pin 1 of chip U1 is: (voltage at pin 3 of chip U1 - voltage at pin 2 of chip U1) × R3 / R1. When the voltage change between the lifting rheostats exceeds the set vibration value, chip U2 conducts and outputs a high level, the integrating circuit composed of chip U3 conducts, pin 6 of chip U3 outputs a high level, chip U4 conducts, the hydraulic cylinder starts to extend downward, and then the deformation of the damping spring increases, increasing the damping between the piston cylinder and the piston rod, thereby reducing the vibration amplitude of that corner of the base plate and reducing the operating vibration of the gas generator set.

[0024] like Figure 2 As shown, a movable structure is also provided below the base plate 1. The movable structure includes a worm gear 11, which stands on the lower surface of the base plate 1. A first conical wheel 12 is fixedly connected to the upper end of the worm gear 11. A rotating cylinder 10 is also provided above the first conical wheel 12. The rotating cylinder 10 penetrates the base plate 1 and can rotate inside the base plate 1. A second conical wheel 13 is also provided on the center surface of the rotating cylinder 10. The first conical wheel 12 and the second conical wheel 13 are meshed by teeth.

[0025] The worm gear 11 is also provided with rotating columns 17 on both sides. The rotating columns 17 stand on the lower surface of the base plate 1. The center surface of the rotating column 17 is also provided with a turbine 18. The worm gear 11 and the turbine 18 are meshed by teeth. The two ends of the rotating column 17 are fixedly connected with support columns 19. The end of the support column 19 is provided with a universal wheel 20.

[0026] The base plate 1 also has a notch on one of its opposite sides, and a crank 14 is provided in the notch of the base plate 1. The crank 14 is in the shape of a crank arm. One end of the crank 14 is located inside the rotating cylinder 10, and the other end of the crank 14 is located inside the notch of the base plate 1. The surface of the crank 14 located inside the rotating cylinder 10 also has a recess. The recess of the crank 14 is provided with a telescopic spring 16 and a stop post 15. The end of the stop post 15 is wedge-shaped. Normally, under the elastic action of the telescopic spring 16, the stop post 15 is pushed against the inner surface of the rotating cylinder 10. The inner surface of the rotating cylinder 10 also has a recess.

[0027] In use, the operator pulls the crank handle 14 out of the notch in the base plate 1. Under the elastic action of the telescopic spring 16, the abutment 15 pops out from the recess in the crank handle 14 and falls into the recess on the inner surface of the rotating drum 10. The operator turns the crank handle 14, which drives the first conical wheel 12 and the second conical wheel 13 to rotate. The rotation of the first conical wheel 12 drives the worm gear 11 to rotate. The rotation of the worm gear 11 drives the turbine 18 and the rotating column 17 to rotate, thereby making the support column 19 and the universal wheel 20 stand upright under the base plate 1, lifting the base plate 1 and the gas generator set off from the ground. The operator can then push the gas generator set to the installation position, which facilitates the installation of the gas generator set.

[0028] The description of this invention is provided for illustrative purposes and is not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.
