Description

Technical Field

[0002] During the process of engineering construction, there are some erection works that need to be completed on a slope surface. For example, an offshore operation platform and a marine transportation system are erected in a shallow sea area.

[0003] When operating on a sloped site, usually through a loading mechanism with an operation platform, such as an engineering vehicle, etc., the operation mechanism such as the module to be erected is transported to the position to be erected. However, due to the angle between the site and the horizontal plane, its operation platform will tilt along with the ground slope, resulting in abnormal operation. Therefore, a leveling mechanism is needed to level the operation platform on the loading mechanism to achieve normal operation. Summary of the Utility Model

[0029] A leveling device 1 is provided on a carrying mechanism. The carrying mechanism can be various vehicles, driving devices, or carrying platforms, etc. In this embodiment, the carrying platform is a tracked vehicle.

[0030] The tracked vehicle includes a chassis 2, tracks 3 symmetrically arranged on both sides of the chassis 2, a mounting frame 4 for mounting the tracks 3, and a working platform. The working platform is connected to the chassis 2 through the leveling device 1 to achieve universal rotation between the working platform and the chassis 2 and adjust the levelness of the working platform.

[0031] The leveling base 10 includes a base body 11 and a connecting part 12. There are multiple connecting parts 12. The center position of the base body 11 is hinged to the chassis 2, and the connection method can adopt a spherical hinge, so that universal rotation can be achieved between the base body 11 and the chassis 2, enabling the leveling base 10 to have four degrees of freedom in four directions. The multiple connecting parts 12 are circumferentially arranged on the base body 11 with the spherical hinge as the center. The connecting part 12 protrudes from the base body 11 and is integrally formed with the base body 11. The connecting part 12 is connected to the mounting bracket 4 through a leveling oil cylinder 14.

[0032] It should be noted that in this embodiment, an avoidance surface 13 is provided on the side wall of the leveling base 10. The avoidance surface 13 is arranged between adjacent connecting parts 12, and the avoidance surface 13 is an arc surface that bends towards the hinge position between the base body 11 and the chassis 2.

[0033] In this embodiment, there are four connecting parts 12. The four connecting parts 12 are respectively connected to the front and rear parts of the two mounting brackets 4 through four leveling oil cylinders 14. The cylinder end of the leveling oil cylinder 14 is universally hinged to the mounting bracket 4, and the piston end of the leveling oil cylinder 14 is universally hinged to the connecting part 12. Taking the connection points between the four leveling oil cylinders 14 and the leveling base 10 as point A and the hinge point between the base body 11 and the chassis 2 as O, the four A points are circumferentially arranged with O as the center. When the tracked vehicle moves to a designated position in the shallow sea area, since the general shallow sea area has a certain slope and is uneven, by adjusting the stroke of the four leveling oil cylinders 14, the absolute level of the leveling base 10 can be achieved.

[0034] All connection points of the leveling oil cylinder 14 adopt universal hinges, resulting in the possibility of the leveling base 10 rotating horizontally. Therefore, 4 positioning oil cylinders 15 with stroke control are arranged at the bottom of the leveling base 10. One end of the positioning oil cylinder 15 is hinged to the bottom of the leveling base 10, and the other end is hinged to the chassis 2. When it is detected that the leveling base 10 rotates, through hydraulic and electric control, it can be restored to the initial state with one key.

[0035] Specifically, the chassis 2 includes a cross beam 21 connecting the two mounting brackets 4. The cross beam 21 is located at the center position of the crawler 3, and the center of the cross beam 21 coincides with the center position of the chassis 2. The center of the base body 11 is universally hinged to the cross beam 21. The hinge structure between the base body 11 and the cross beam 21 can adopt a spherical hinge or the form of a multi-axis hinge. Two positioning oil cylinders 15 are respectively arranged on both sides of the cross beam 21. One end of the positioning oil cylinder 15 is hinged to the cross beam 21, and the other ends are respectively located on the four OA line segments. The hinge points between the positioning oil cylinders 15 and the cross beam 21 are symmetrically arranged on both sides of the cross beam 21.

[0036] The implementation principle of this application is:

[0037] After the crawler vehicle moves to the designated position in the shallow sea area, start the four leveling cylinders 14, and control the rotation of the leveling base 10 until the top surface of the leveling base 10 is parallel to the horizontal plane. Preferably, a monitoring device for monitoring the levelness of the top surface of the leveling base 10 can be provided on the leveling base 10. After the leveling base 10 is in a horizontal state, control the positioning cylinder 15 to close, and the positioning cylinder 15 locks the relative position relationship between the leveling base 10 and the leveling cylinders 14, so as to quickly control the leveling base 10 to adjust and maintain an absolute horizontal state, so that the working mechanism on the working platform can work normally.

[0038] On the other hand, when the crawler vehicle moves along the inclined seabed in the shallow sea area, or when the crawler vehicle stops on the inclined seabed in the shallow sea area, the leveling cylinders 14 mainly bear the vertical force applied by the leveling base 10 on the chassis 2 of the crawler vehicle, and the positioning cylinder 15 can disperse the horizontal force applied by the leveling base 10 on the chassis 2 of the crawler vehicle.

[0039] Inspired by the above ideal embodiments according to the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of the present invention. The technical scope of the present invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
