Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic equipment technology, and in particular to a self-leveling hydraulic jacking device. 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). The term "hydraulic system" usually refers to the hydraulic transmission system. Hydraulic lifting systems are frequently used in industrial production, especially in container shipping. Containers are typically transferred between platforms using hoisting methods. However, in actual transfer processes, leveling the containers is difficult, making them prone to shifting and creating transportation hazards. Utility Model Content
[0003] The technical problem this utility model aims to solve is that in the field of container transportation, containers are generally transferred between platforms by hoisting. However, in the actual transfer process, it is not convenient to level the containers, which makes it easy for the containers to deviate during the transfer process and cause transportation dangers.
[0004] To solve the above problems, this utility model provides a self-leveling hydraulic lifting device. The hydraulic outriggers are provided with rotating ears, and at least two rotating ears are connected by a rotating shaft to rotate synchronously. The rotating shaft is provided with fixed ears corresponding to the rotating ears, and the fixed ears are provided with connecting parts so that the hydraulic outriggers can be installed on the container. One of the fixed ears is provided with a motor, and the output end of the motor is connected to a worm gear. The rotating shaft is provided with a worm wheel corresponding to the worm gear.
[0005] The self-leveling hydraulic lifting device provided by this utility model also has the following technical features:
[0006] The container is equipped with corner fittings at its corners, and the corner fittings have holes. The connecting component is an L-shaped connecting plate with connecting holes. The connecting holes are set to correspond to the openings and are connected by bolts.
[0007] The connecting component is a straight plate with through holes, and the container has threaded holes. The threaded holes and through holes are correspondingly arranged and connected by bolts.
[0008] The hydraulic outrigger is connected to the rotating lug via a cross arm, and a support cylinder is provided on the fixed lug, which is rotatably sleeved on the rotating shaft.
[0009] The hydraulic outrigger includes a hydraulic cylinder and a telescopic rod, with a support pad connected to the free end of the telescopic rod.
[0010] The output end of the motor is connected to the worm gear via a flexible coupling.
[0011] The container is equipped with tilt sensors and control modules that are connected to the hydraulic outriggers.
[0012] This invention offers the following advantages: During actual transport, the hydraulic outriggers are mounted on the container via connecting components, and their lifting action facilitates container leveling, preventing deviation and potential transport hazards. Simultaneously, the motor's output drives a worm gear, which in turn rotates the worm wheel and shaft, causing the rotating lugs to rotate relative to the fixed lugs and the container. This automatically adjusts and locks the orientation of the hydraulic outriggers, allowing the container transport process to adapt to platforms of different sizes, thus broadening its applicability.

[0017] 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.
[0018] like Figures 1 to 4 As shown, the self-leveling hydraulic lifting device of this utility model has a hydraulic outrigger 10 with a rotating lug 11. At least two rotating lugs 11 are connected by a rotating shaft 12 to rotate synchronously. The rotating shaft 12 is provided with a fixed lug 13 corresponding to the rotating lug 11. The fixed lug 13 is provided with a connecting component so that the hydraulic outrigger 10 can be installed on the container 14. One of the fixed lugs 13 is provided with a motor 15. The output end of the motor 15 is connected to a worm gear 16. The rotating shaft 12 is provided with a worm wheel 17 corresponding to the worm gear 16.
[0019] During actual transport, the hydraulic outriggers 10 are mounted on the container 14 via connecting components. Their lifting action facilitates leveling of the container 14, preventing deviation and potential transport hazards. Simultaneously, the output of the motor 15 drives the worm gear 16, which in turn drives the worm wheel 17 and the rotating shaft 12. This causes the rotating lug 11 to rotate relative to the fixed lug 13 and the container 14, automatically adjusting and locking the orientation of the hydraulic outriggers 10. This allows the container 14 to be transported on platforms of different sizes, making it widely applicable.
[0020] Among them, since the worm gear 17 and worm 16 have a self-locking function, the orientation of the hydraulic outrigger 10 can be automatically locked.
[0021] When transferring container 14 to a freight vehicle or other platform, the space at the bottom of container 14 varies depending on the orientation of the hydraulic outriggers 10, thus adapting it to platforms of different sizes.
[0022] The motor 15 is equipped with a corresponding power supply and controller to facilitate the adjustment of its speed and direction. The specific location of the motor 15 can be selected and set according to actual needs to avoid motion interference when the hydraulic outrigger 10 rotates.
[0023] The rotating ear 11 and the rotating shaft 12 can be integrally formed by welding, casting or other methods so that the two can rotate synchronously.
[0024] Preferably, see Figure 1 , Figure 3 The container 14 is provided with corner fittings 18 at its corners, and the corner fittings 18 are provided with holes 19. The connecting component is an L-shaped connecting plate 20, and the L-shaped connecting plate 20 is provided with connecting holes 21. The connecting holes 21 are correspondingly set with the holes 19 and are connected by bolts.
[0025] In existing technology, to connect and secure multiple containers 14 and ensure their safe stacking and movement during transportation, corner fittings 18 are provided at the corners of the containers 14. The upper side and two outer sides of the corner fittings 18 have holes 19 that can engage with twist locks. L-shaped connecting plates 20 are fitted to the two outer holes 19 and connected with bolts and nuts to install the L-shaped connecting plates 20 onto the containers 14. Additionally, the connecting holes 21 are vertically elongated holes to facilitate adjustment of the height of the hydraulic outriggers 10, making them suitable for containers 14 of different sizes and corresponding corner fittings 18 within a limited range.
[0026] As a structural variation of this utility model, see 4, the connecting component is a straight plate 22, which has a through hole, and the container 14 has a threaded hole, which is correspondingly set with the through hole and connected by bolts.
[0027] Preferably, the hydraulic outrigger 10 is connected to the rotating ear 11 via the cross arm 23, and the fixed ear 13 is provided with a support cylinder 24, which is rotatably sleeved on the rotating shaft 12.
[0028] The fixing ear 13 and the support cylinder 24 can be integrally formed by welding, casting or other methods so that the two can rotate synchronously.
[0029] Preferably, the hydraulic outrigger 10 includes a hydraulic cylinder 25 and a telescopic rod 26. The free end of the telescopic rod 26 is connected to a support pad 27, and the free end of the telescopic rod 26 is connected to the support pad 27 through a ball head and a ball seat.
[0030] Preferably, the output end of the motor 15 is connected to the worm gear 16 via a flexible coupling 28.
[0031] By incorporating a flexible coupling 28, the tendency of the worm gear 17 to rotate is eliminated, thus preventing the transmission of force from the worm 16 to the output end of the motor 15 and avoiding damage to the motor 15 and a reduction in its service life. The specific structure and working principle of the flexible coupling 28 are existing technologies and will not be described in detail here.
[0032] Preferably, the container 14 is equipped with a tilt sensor and a control module connected to the hydraulic outriggers 10. The tilt sensor detects the tilt angle of the container 14 in real time, converts it into an electrical signal, and transmits it to the control module. The control module analyzes and processes the electrical signal and activates the hydraulic outriggers 10 at the corresponding positions to level the container 14 in real time. The hydraulic outriggers 10 are equipped with corresponding controllers, which are connected to the control module.
[0033] The working principle of this utility model is as follows:
[0034] During actual transport, the hydraulic outriggers 10 are mounted on the container 14 by correspondingly engaging the L-shaped connecting plate 20 with the two outer holes 19 on the corner fitting 18. An inclination sensor detects the inclination angle of the container 14 in real time, converting it into an electrical signal which is then transmitted to the control module. The control module analyzes and processes the electrical signal and activates the corresponding hydraulic outriggers 10 to level the container 14 in real time, preventing deviation during transport and potential transportation hazards. Simultaneously, the output of the motor 15 drives the worm gear 16 to rotate, which in turn drives the worm wheel 17 and the rotating shaft 12, causing the rotating lug 11 to rotate relative to the fixed lug 13 and the container 14. This automatically adjusts and locks the orientation of the hydraulic outriggers 10, allowing the container 14 to be transported on platforms of different sizes, thus broadening its applicability.
[0035] 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.
