Description

Technical Field

[0001] This utility model relates to the field of hydraulic equipment technology, and in particular to a self-leveling hydraulic control system. Background Technology

[0002] A hydraulic system generally consists of power components, actuators, control components, auxiliary components (accessories), and hydraulic oil. Hydraulic systems are further divided into hydraulic transmission systems and hydraulic control systems. The primary function of a hydraulic system is to transmit power and motion, while the hydraulic control system ensures that the hydraulic system output meets specific performance requirements (especially dynamic performance). Currently, most hydraulic jacking mechanisms are limited to use in environments with smooth road surfaces. When facing uneven road surfaces, their stability and safety factor decrease significantly. Chinese utility model patent CN221420623U discloses a hydraulic outrigger leveling device with four independently adjustable and foldable outriggers, offering good leveling performance. However, the above solution has a drawback: it is inconvenient to move the entire device when the support plate is loaded with equipment or goods, making it difficult to use. Utility Model Content

[0003] The technical problem this invention aims to solve is that the support plate of existing hydraulic leveling devices is inconvenient to move as a whole when loading equipment or goods, making them difficult to use.

[0004] To address the aforementioned issues, this utility model provides a self-leveling hydraulic control system. The bottom of the support plate is equipped with a hydraulic pump station and a tilt sensor connected to a PLC controller. Support ears are located at the corners of the support plate, and a horizontal arm is mounted on each support ear. A hydraulic cylinder is located at the end of each horizontal arm, and the hydraulic cylinder is connected to the hydraulic pump station via hydraulic lines. A support base is connected to the telescopic end of the hydraulic cylinder. An installation groove is formed on the lower surface of the support base, and a lifting cylinder is installed within the installation groove. A ball groove is formed at the telescopic end of the lifting cylinder, and a rolling ball is located within the ball groove.

[0005] The self-leveling hydraulic control system provided by this utility model also has the following technical features:

[0006] The support plate is provided with corner plates at each corner, and a mounting plate is connected to one end of the support side lug. The mounting plate is connected to the corner plate by bolts.

[0007] The other end of the supporting side ear is connected to a supporting cylinder. One end of the cross arm is connected to a hydraulic cylinder, and the other end is connected to a rotating side ear. An inner shaft is integrally formed on the rotating side ear, and the inner shaft is rotatably inserted into the supporting cylinder.

[0008] A pin is rotatably provided on the rotating side ear. One end of the pin is provided with a handle, and the other end is provided with an eccentric locking disc. A circular groove is provided on the side of the supporting side ear near the pin. The locking disc is located in the circular groove, and the outer surface of the locking disc abuts against the inner surface of the circular groove.

[0009] The circular groove is coaxially arranged with the inner shaft and the support cylinder.

[0010] The telescopic end of the hydraulic cylinder is connected to a support ball, and the upper surface of the support seat is provided with a ball groove corresponding to the support ball.

[0011] This invention has the following advantages: The tilt angle of the support plate is detected in real time by a tilt sensor and converted into an electrical signal, which is then sent to the PLC controller. The PLC controller analyzes and processes the electrical signal and controls the hydraulic pump station to operate. Oil is supplied to the hydraulic cylinders at corresponding positions via hydraulic pipelines, causing the extension and retraction ends of the hydraulic cylinders to extend or retract, thus changing the angle of the support plate until it is leveled. When the support plate is loaded with equipment or goods and needs to be moved as a whole, the extension and retraction ends of the lifting cylinders are extended, causing the rolling ball to contact the ground and roll, enabling the support plate and its loaded equipment or goods to be moved as a whole. This design is convenient to use. Attached Figure Description

[0015] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0016] like Figures 1 to 3 As shown, the self-leveling hydraulic control system of this utility model has a hydraulic pump station 12 and a tilt sensor 13 connected to the PLC controller 11 at the bottom of the support plate 10. Support side ears 14 are provided at the corners of the support plate 10. A cross arm 15 is provided on the support side ear 14. A hydraulic cylinder 16 is provided at the end of the cross arm 15. The hydraulic cylinder 16 is connected to the hydraulic pump station 12 through a hydraulic pipeline 17. The telescopic end of the hydraulic cylinder 16 is connected to a support seat 18. An installation groove 19 is provided on the lower surface of the support seat 18. A lifting cylinder 20 is provided in the installation groove 19. A ball groove 21 is provided on the telescopic end of the lifting cylinder 20. A rolling ball 22 is provided in the ball groove 21.

[0017] The tilt angle of the support plate 10 is detected in real time by the tilt sensor 13 and converted into an electrical signal, which is sent to the PLC controller 11. The PLC controller 11 analyzes and processes the electrical signal and controls the hydraulic pump station 12 to work. Oil is supplied to the hydraulic cylinders 16 at the corresponding positions through the hydraulic pipeline 17, causing the extension and retraction ends of the hydraulic cylinders 16 to extend or retract, thereby changing the angle of the support plate 10 until it is leveled. When the support plate 10 is loaded with equipment or goods and needs to be moved as a whole, the extension and retraction ends of the lifting cylinder 20 are extended, causing the rolling ball 22 to contact the ground and roll, thereby moving the support plate 10 and the loaded equipment or goods as a whole. This is convenient to use. Of course, when there is no need to move the support plate 10, the extension and retraction ends of the lifting cylinder 20 are retracted, causing the rolling ball 22 to retract into the mounting groove 19. At this time, the lower surface of the support base 18 is in contact with the ground.

[0018] The PLC controller 11 is electrically connected to the tilt sensor 13. The hydraulic pump station 12 includes: a motor to convert electrical energy into mechanical energy; a hydraulic pump to convert the mechanical energy from the motor into hydraulic energy, generating pressure by drawing in and discharging hydraulic oil; an oil tank for storing hydraulic oil; a control valve block containing various types of valves, such as directional control valves, pressure control valves, and flow control valves, for regulating the direction, pressure, and flow rate of the hydraulic oil to ensure the system operates in a predetermined manner; a filter to keep the hydraulic oil clean and prevent impurities from entering the system; an accumulator to store and release hydraulic energy to help stabilize system pressure; sensors for monitoring system parameters such as temperature and pressure, and for automated management via a control module electrically connected to the PLC controller 11; and a connection interface providing inlet and outlet connections to the hydraulic cylinder 16, as well as interfaces for power and signal lines. In addition, the lifting cylinder 20 is also supplied with oil and controlled by the hydraulic pump station 12. The specific connection pipeline is not shown. After the hydraulic cylinder 16 levels the support plate 10, the hydraulic pump station 12 can control the extension and retraction ends of all lifting cylinders 20 to extend or retract by the same distance, so that all corresponding rolling balls 22 simultaneously contact or detach from the ground.

[0019] The bottom of the support plate 10 is equipped with a control box 23, and the PLC controller 11 and the tilt sensor 13 are located inside the control box 23.

[0020] The support lugs 14, crossarms 15, and hydraulic cylinders 16 can be configured in one or more sets to improve support stability. The support plate 10 can be used to load and unload containers, mobile cabins, mobile workstations, mobile power stations, and other equipment or goods.

[0021] Preferably, corner plates 24 are provided at the corners of the support plate 10, and one end of the support side ear 14 is connected to a mounting plate 25, which is connected to the corner plate 24 by bolts.

[0022] Preferably, the other end of the supporting side ear 14 is connected to a supporting cylinder 26, one end of the cross arm 15 is connected to a hydraulic cylinder 16, and the other end is connected to a rotating side ear 27. An inner shaft 28 is integrally formed on the rotating side ear 27, and the inner shaft 28 is rotatably inserted into the supporting cylinder 26, so that the rotating side ear 27 rotates relative to the supporting side ear 14, that is, the hydraulic cylinder 16 can rotate relative to the supporting plate 10. When the hydraulic cylinder 16 rotates to the folded position, it saves space. When the hydraulic cylinder 16 rotates to the unfolded position, it increases the supporting area of ​​the supporting plate 10 and improves the supporting stability.

[0023] Preferably, a pin 31 is rotatably provided on the rotating side ear 27. One end of the pin 31 is provided with a handle 32 and the other end is provided with an eccentric locking disc 33. A circular groove 34 is provided on the side of the supporting side ear 14 near the pin 31. The locking disc 33 is disposed in the circular groove 34, and the outer surface of the locking disc 33 abuts against the inner surface of the circular groove 34.

[0024] After adjusting the hydraulic cylinder 16 to rotate relative to the support plate 10 to a certain angle, rotate the handle 32 and the locking pin 31 so that the eccentric side of the locking disc 33 and the pin 31 abuts against the inner surface of the circular groove 34, so that the rotating side ear 27 is locked relative to the support side ear 14, preventing the rotation angle of the hydraulic cylinder 16 from changing and improving the stability of the support.

[0025] Preferably, the circular groove 34 is coaxially arranged with the inner shaft 28 and the support cylinder 26.

[0026] Preferably, the telescopic end of the hydraulic cylinder 16 is connected to a support ball 35, and the upper surface of the support base 18 is provided with a ball groove 36 corresponding to the support ball 35.

[0027] The working principle of this utility model is as follows:

[0028] The support plate 10 is used to load equipment or goods. The tilt angle of the support plate 10 is detected in real time by the tilt sensor 13 and converted into an electrical signal and sent to the PLC controller 11. The PLC controller 11 analyzes and processes the electrical signal and controls the hydraulic pump station 12 to work. Oil is supplied to the hydraulic cylinder 16 at the corresponding position through the hydraulic pipeline 17, so that the extension end of the hydraulic cylinder 16 extends or retracts, so that the angle of the support plate 10 changes until it is leveled. When the support plate 10 is loaded with equipment or goods and needs to be moved as a whole, the extension end of the lifting cylinder 20 is extended, so that the rolling ball 22 contacts the ground and rolls, so that the support plate 10 and the loaded equipment or goods can be moved as a whole, which is convenient to use.

[0029] The rotating side ear 27 can be manually operated according to actual needs to rotate relative to the supporting side ear 14. That is, the hydraulic cylinder 16 can rotate relative to the support plate 10 to fold or unfold. After adjusting the hydraulic cylinder 16 to rotate relative to the support plate 10 to a certain angle, rotate the handle 32 and the locking pin 31 so that the eccentric side of the locking disc 33 and the pin 31 abuts against the inner surface of the circular groove 34, so that the rotating side ear 27 is locked relative to the supporting side ear 14, preventing the rotation angle of the hydraulic cylinder 16 from changing and improving the stability of the support.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
