Description

Technical Field

[0001] This utility model relates to the field of hydraulic device technology, and in particular to a hydraulic device for rapid pressurization. Background Technology

[0002] Hydraulic transmission uses liquid as the working medium and utilizes the pressure energy of the liquid to transmit power. The actuator in the hydraulic system is the direct force-applying device and is particularly important in the hydraulic system. Hydraulic devices are present in many modern automated equipment. They are stable in operation, have a large lifting capacity, and are highly favored by people in this field.

[0003] Existing hydraulic devices suffer from slow pressurization speed and insufficient operational stability when faced with sudden increases in load. They lack structures and functions for rapid pressurization, and their overall functionality and practicality need to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulic device for rapid pressurization that can perform a secondary pressurization operation without increasing the original oil supply load when faced with a sudden increase in load, thereby achieving rapid pressurization and improving work stability.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A rapid pressurization hydraulic device includes a control base and a hydraulic cylinder. The hydraulic cylinder has a first oil chamber and a second oil chamber inside. The control base has two oil passages inside. One end of the first oil chamber is connected to a first fluid guide hose, and one end of the second oil chamber is connected to a second fluid guide hose. One end of the first and second fluid guide hoses are respectively connected to the two oil passages of the control base. A tank is fixedly connected to the upper surface of the control base. One end of the tank communicates with the interior of the second fluid guide hose. A third piston block is slidably installed inside the tank. Both the tank and the second oil chamber are filled with hydraulic oil. A rotating seat is fixedly installed on the upper surface of the control base. A worm gear is rotatably installed on the inner side of the rotating seat. A threaded hole is provided at the central axis of the worm gear, and a lead screw passes through the threaded hole. One end of the lead screw corresponds to one end opening of the tank.

[0007] By adopting the above technical solution, hydraulic oil inside the tank can be introduced into the second oil chamber when needed, thereby pushing the first piston block to slide inside the second oil chamber, which can improve the hydraulic lifting force and speed of the device and effectively improve its overall practicality.

[0008] Furthermore, a limiting groove is provided on the side surface of the lead screw, and a limiting block is provided on the rotating seat, the limiting block being engaged inside the limiting groove.

[0009] By adopting the above technical solution, it is ensured that the rotation of the worm gear can drive the lead screw to move axially.

[0010] Furthermore, a fixed seat is fixedly installed on the upper surface of the control seat, and a worm gear is rotatably installed on the inner side of the fixed seat, the worm gear being meshed with a worm wheel.

[0011] By adopting the above technical solution, it is ensured that the rotation of the worm can drive the rotation of the worm wheel.

[0012] Furthermore, a motor is fixedly mounted on the upper surface of the fixed base, and one end of the rotating shaft of the motor is fixedly connected to one end of the worm gear.

[0013] By adopting the above technical solution, a motor can be used to drive the worm gear to rotate.

[0014] Furthermore, a second piston block is slidably installed inside the first oil chamber, and a second telescopic member is fixedly connected to the end face of the second piston block. A circular first piston block is slidably installed inside the second oil chamber, and a first telescopic member is fixedly connected to the end face of the first piston block.

[0015] By adopting the above technical solution, it is ensured that the entry of hydraulic oil can push the extension of the first and second telescopic components.

[0016] Furthermore, one end of the second telescopic member is fixedly connected to a linkage block, and two first telescopic members are provided, with one end of each of the two first telescopic members fixedly connected to the linkage block.

[0017] By adopting the above technical solutions, the overall linkage of the device can be effectively improved.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] This invention utilizes an internal oil passage within the control seat to guide external hydraulic oil into the first guide hose, which then enters the first oil chamber. This allows the second telescopic component to extend. When increased hydraulic pressure is required, the motor is activated, driving the worm gear to rotate. The worm gear's rotation, in turn, drives the worm wheel. Since the worm wheel is threaded onto the outside of the lead screw, and the lead screw slides against the rotating seat, the rotation of the worm wheel allows the lead screw to move axially. One end of the lead screw passes through a through-hole at the end of the tank and rests on the side surface of the third piston block, pushing it to slide inside the tank. This effectively pushes the hydraulic oil from the tank along the second guide hose into the second oil chamber, causing the first telescopic component to extend. Simultaneously, hydraulic oil is introduced into both chambers, enabling rapid pressurization. Furthermore, because the first and second oil chambers are independent, the stability of the device's operation is effectively improved. Attached Figure Description

[0024] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Reference Figure 1 , Figure 2 , Figure 3 A rapid pressurization hydraulic device includes a control base 6 and a hydraulic cylinder 1. The hydraulic cylinder 1 has a first oil chamber 14 and a second oil chamber 15 inside. The control base 6 has two oil passages inside. One end of the first oil chamber 14 is connected to a first fluid guide hose 4, and one end of the second oil chamber 15 is connected to a second fluid guide hose 5. One end of the first fluid guide hose 4 and the second fluid guide hose 5 are respectively connected to the two oil passages of the control base 6. A tank 7 is fixedly connected to the upper surface of the control base 6. One end of the tank 7 communicates with the interior of the second fluid guide hose 5. A first fluid guide hose 14 is slidably installed inside the tank 7. The three piston blocks 18, the tank 7, and the second oil chamber 15 are all filled with hydraulic oil. Under normal conditions, hydraulic oil can be injected into the first oil chamber 14 alone, and the hydraulic oil in the first oil chamber 14 can drive the device to extend and retract. When a rapid increase in lifting force is required, a force is applied to one end face of the third piston block 18, and the hydraulic oil in the tank 7 is introduced into the second oil chamber 15 through the third piston block 18. At this time, the hydraulic oil in the first oil chamber 14 and the second oil chamber 15 can drive the device together, which can quickly realize the pressurization operation of the device.

[0026] Reference Figure 1Figure 3 shows a rotating seat 8 fixedly mounted on the upper surface of the control seat 6. A worm gear 10 is rotatably mounted on the inner side of the rotating seat 8. A threaded hole is provided at the central shaft position of the worm gear 10, and a lead screw 9 passes through the threaded hole. One end of the lead screw 9 corresponds to one end opening of the tank body 7. A limit groove is provided on the side surface of the lead screw 9. A limit block is provided on the rotating seat 8, and the limit block is engaged inside the limit groove. A fixed seat 12 is fixedly mounted on the upper surface of the control seat 6. A worm gear 11 is rotatably mounted on the inner side of the fixed seat 12. The worm gear 11 is meshed with the worm gear 10. A motor 13 is fixedly mounted on the upper end face of the fixed seat 12. One end of the rotating shaft of the motor 13 is fixedly connected to one end of the worm gear 11. The motor 13 can be started when the pressure is increased, utilizing... Motor 13 drives worm 11 to rotate. Since worm 11 is meshed with worm wheel 10, the rotation of worm 11 can drive worm wheel 10 to rotate. Since lead screw 9 is slidably connected to rotating seat 8, and the limiting block on rotating seat 8 is engaged in the limiting groove on the side surface of lead screw 9, and worm wheel 10 is threaded onto the outside of lead screw 9, the rotation of worm wheel 10 can drive lead screw 9 to move axially, so that one end of lead screw 9 can pass through the through hole on the end face of tank 7 and enter the interior of tank 7, and abut against the end face of third piston block 18, so that third piston block 18 moves inside tank 7, ensuring that hydraulic oil inside tank 7 can enter the interior of second oil chamber 15, realizing rapid pressurization operation, and effectively improving the working stability of the entire device.

[0027] Reference Figure 1 Figure 2 shows that a second piston block 17 is slidably installed inside the first oil chamber 14, and a second telescopic member 3 is fixedly connected to the end face of the second piston block 17. A circular first piston block 16 is slidably installed inside the second oil chamber 15, and a first telescopic member 2 is fixedly connected to the end face of the first piston block 16. A linkage block is fixedly connected to one end of the second telescopic member 3. There are two first telescopic members 2, and one end of each of the two first telescopic members 2 is fixedly connected to the linkage block. The sliding of the first piston block 16 and the second piston block 17 can drive the extension and retraction of the first telescopic member 2 and the second telescopic member 3, ensuring that the device can perform effective extension and retraction operations.

[0028] Working principle: In use, first install the device in the designated location, then connect the external oil supply system. When pressurization is not required, inject hydraulic oil into the first oil chamber 14. At this time, the second piston block 17 is driven by the hydraulic oil to achieve extension and retraction. During this process, under the linkage of the linkage block, the first telescopic member 2 and the first piston block 16 move synchronously. Simultaneously, driven by the hydraulic oil inside the tank 7, the third piston block 18 moves synchronously. When pressurization is required, start the motor 13, which drives the worm gear 11 to rotate. Since the worm gear 11 is meshed with the worm wheel 10, the rotation of the worm gear 11 can drive the worm wheel 10 to rotate. Furthermore, since the lead screw 9 is slidably connected to the rotating seat 8, and the limiting block on the rotating seat 8 engages with the limiting block on the side surface of the lead screw 9... Within the slot, the worm gear 10 is threaded onto the outside of the lead screw 9. Therefore, the rotation of the worm gear 10 can drive the lead screw 9 to move axially, allowing one end of the lead screw 9 to pass through the through hole on the end face of the tank 7 and enter the interior of the tank 7, abutting against the end face of the third piston block 18. This allows the third piston block 18 to move inside the tank 7, ensuring that the hydraulic oil inside the tank 7 can enter the interior of the second oil chamber 15. This enables high-pressure output. During daily operation, when the hydraulic device is extended, the lead screw 9 can be inserted into the interior of the tank 7 and pressed against the side surface of the third piston block 18, ensuring that the hydraulic oil inside the second oil chamber 15 cannot flow back into the interior of the tank 7. This improves the stability of the hydraulic device and provides double safety for the device.

Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
