Description

Technical Field

[0002] With the continuous improvement of people's material and cultural living standards, the demand for entertainment has also shown a trend of increasing in quantity and improving in quality. For example, the Sambata amusement equipment adopts full hydraulic control, which integrates lifting, revolution and rotation, allowing tourists to experience a different passion in dynamic music and exciting rotation.

[0003] The hydraulic cylinder body of the hydraulic lifting system of the amusement equipment is installed on the equipment column. The two cylinders act simultaneously to lift the load (structure and passengers). Two sets of guide mechanisms are designed in the load structure. They are lifted to the operating high point and the pressure is maintained to keep the load at a high position. After the operating time is satisfied, the load is lowered to the bottom of the equipment. During operation, in order to ensure minimal impact, the synchronous and smooth descent of 0.5 meters in the final stroke of the descent is particularly important. The two double-acting multi-stage cylinders commonly used in the existing amusement equipment hydraulic system execution module have poor performance in load balancing ability, reliability and maintenance. In addition, due to errors in the processing technology and service life of various hydraulic system components, the synchronization performance of the hydraulic cylinders will be affected, resulting in poor synchronization of the amusement equipment.

The oil cylinder rodless cavity inlet and outlet oil regulating valve block 7.21 is the basis of the oil cylinder rodless cavity inlet and outlet oil regulating valve group 7.2. It is both a carrier for the other components of the oil cylinder rodless cavity inlet and outlet oil regulating valve group 7.2 and a channel body for the oil circuit connection of the other components of the rodless cavity inlet and outlet oil regulating valve group 7.2. The first pipeline explosion-proof valve 7.22 is arranged at the rodless cavity oil port 7.14 of the secondary hydraulic cylinder 7.1. It is a pressure relief device for the high-pressure rubber hose that is prone to explosion of the oil inlet of the cylinder. It mainly plays a protective role to prevent the occurrence of safety accidents. The return oil one-way throttle valve 7.23 is used to adjust the retraction speed of the secondary hydraulic cylinder 7.1, and the inlet oil one-way throttle valve 7.24 is used to adjust the extension speed of the secondary hydraulic cylinder 7.1. The externally controlled hydraulic one-way valve 7.25 is both a control valve for the oil flow rate of the secondary hydraulic cylinder 7.1 and a safety valve for the oil inlet of the secondary hydraulic cylinder 7.1; the function of the pressure measuring device 7.26 is to connect a pressure gauge to monitor the oil inlet pressure of the rodless chamber 7.16 of the secondary hydraulic cylinder 7.1.The oil inlet and outlet regulating valve group 7.3 of the oil cylinder rod chamber includes an oil replenishment check valve 7.31, a third throttle valve 7.32, an oil drain check valve 7.33 and a second pipeline explosion-proof valve 7.34. The oil replenishment check valve 7.31 functions as a safety valve for replenishing oil in the rod chamber 7.17 of the secondary hydraulic oil cylinder 7.1 and is directly connected to the oil replenishment circuit of the oil cylinder reversing valve group 6. The third throttle valve 7.32, the oil drain check valve 7.33 and the second pipeline explosion-proof valve 7.34 form an oil drain circuit of the rod chamber 7.17 of the secondary hydraulic oil cylinder 7.1 and are directly connected to the oil cylinder reversing valve group 6. The oil leakage circuit of the valve group 6, the function of the third throttle valve 7.32 is to adjust the flow of oil leakage from the rod chamber 7.17 of the secondary hydraulic cylinder 7.1, and the function of the oil leakage check valve 7.33 is a safety valve for oil leakage from the rod chamber 7.17 of the secondary hydraulic cylinder 7.1; the second pipeline explosion-proof valve 7.34 is arranged in the oil leakage pipeline of the rod chamber oil port 7.15 of the secondary hydraulic cylinder 7.1, and the oil leakage hose of the rod chamber 17 is prevented from being damaged, thereby preventing oil leakage from the rod chamber 7.17 of the secondary hydraulic cylinder 7.1, and mainly plays a protective role to prevent the occurrence of safety accidents.

[0042] Before work, the rod chamber 7.17 of the secondary hydraulic cylinder 7.1 needs to be filled with hydraulic oil. The extension process of the secondary hydraulic cylinder 7.1 is as follows: oil enters the rodless chamber 7.16 of the secondary hydraulic cylinder 7.1, and the pressure increases, thereby pushing the piston rod 7.12 to extend outward. At the same time, the volume of the rod chamber 7.17 becomes smaller, and the increased pressure forces the hydraulic oil to flow to the plunger chamber 7.19. The oil filling in the plunger chamber 7.19 forces the plunger rod 7.13 to extend outward until the piston rod 7.12 moves to the maximum stroke. At the same time, the volume of the rod chamber 7.17 is zero, and the hydraulic oil in the rod chamber 7.17 completely flows to the plunger chamber 7.18. The retraction process of the secondary hydraulic cylinder 7.1 is as follows: oil flows out of the rodless chamber 7.16 of the secondary hydraulic cylinder 7.1, the pressure decreases, and the piston rod 7.12 retracts. At the same time, the volume of the rod chamber 7.17 increases from zero, forcing the hydraulic oil to flow from the plunger chamber 7.18 to the rod chamber 7.17. The plunger rod 7.13 retracts until the stroke of the piston rod 7.12 is zero. At the same time, the volume of the rod chamber 7.17 is the largest, and the hydraulic oil in the plunger chamber 7.18 completely flows to the rod chamber 7.17.

[0043] Specifically, see Figure 1 and Figure 10The circulating cooling assembly 8 is arranged on one side of the top of the hydraulic oil tank 2.1 and is connected to the cooling motor pump assembly 3.3 that supplies oil to the cooling oil circuit. Its function is to cool the hydraulic oil of the hydraulic lifting system of the amusement equipment. The circulating cooling assembly 8 is mainly composed of an air cooler 8.1, a bypass valve 8.2, and a second pressure measuring joint 8.3. The bypass valve 8.2 is fixedly connected to one side of the air cooler 8.1, and the second pressure measuring joint 8.3 is fixedly connected to the bypass valve 8.2. The air cooler 8.1 uses air as a heat exchange medium for heat exchange. The air takes away the heat of the hydraulic lifting system of the amusement equipment. The heat dissipation effect of the air cooler 8.1 mainly depends on the heat exchange area and air volume of its component radiator. The bypass valve 8.2 is a safety device of the circulating cooling assembly 8. When the flow rate is greater than the maximum flow rate of the air cooler, the excess hydraulic oil is released from the bypass valve 8.2 to prevent the pressure of the cooling oil circuit from exceeding the maximum pressure of the air cooler. The second pressure measuring joint 8.3 is connected to a pressure gauge to directly monitor the cooling pressure of the air cooler 8.1.

[0044] Working Principle: The working principle of hydraulic system is mainly based on Pascal's law, which is a principle of fluid statics that states that in a closed liquid, pressure will be transmitted uniformly from one point to all other points.
