Description

Technical Field

[0001] This patent relates to the technical field of crane bases, specifically to an anti-rollover crane base. Background Art

[0002] A Chinese patent for a rust-proof crane base (CN202220447928.4) proposes a crane base, which has a rust-proof effect, but the side of the base lacks an anti-rollover structure when in use. When the crane is subjected to uneven force, the base is prone to rollover, posing a safety hazard;

[0003] Some crane bases are also provided with an anti-rollover grounding plate structure. In order to facilitate walking, walking wheels are installed at the bottom of the grounding plate. However, the walking wheels are always supported on the ground, and long-term load-bearing can easily damage the walking wheels. For this reason, we propose an anti-rollover crane base.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0021] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 This patent provides a technical solution: an anti-rollover crane base, including a base body 1, a universal wheel is installed at the bottom of the base body 1, a cross bar 2 is fixedly installed at both ends of the base body 1, a vertical pole 3 is fixedly installed at the end of the cross bar 2, and a grounding seat 4 is fixedly installed at the bottom of the vertical pole 3;

[0022] The grounding seat 4 includes a plate body 5 and a transverse plate 8. A mounting groove 6 is provided at the bottom of the plate body 5. A first threaded hole 7 is provided on the right side of the top wall of the mounting groove 6. The end of the transverse plate 8 is fixedly mounted on the side wall of the vertical pole 3. The transverse plate 8 is located on the upper side of the plate body 5. A second threaded hole 9 is provided on the top of the transverse plate 8. A screw 10 is screwed in the second threaded hole 9. A universal wheel 11 is fixedly mounted on the bottom end of the screw 10 through the first threaded hole 7. The universal wheel 11 is located in the mounting groove 6.

[0023] When the whole needs to be moved, the screw 10 can be rotated to drive the universal wheel 11 to move downward, and the universal wheel 11 is supported on the ground. In the process of moving the whole base, the ground can also be supported by structures such as the cross bar 2, the vertical pole 3 and the grounding seat 4, thereby increasing the smoothness of movement.

[0024] A circular groove 12 is provided at the bottom of the transverse plate 8, and a bearing 13 is fixedly installed on the inner wall of the circular groove 12. The outer wall of the outer ring of the bearing 13 is fixedly installed on the inner wall of the circular groove 12. A connecting ring 14 is fixedly installed on the bottom of the inner ring of the bearing 13. An externally threaded tube 15 is fixedly installed on the bottom of the connecting ring 14. The outer wall of the externally threaded tube 15 is screwed on the inner wall of the first threaded hole 7. A limiting sliding hole 16 is provided on the left side of the top wall of the mounting groove 6. The inner wall of the limiting sliding hole 16 slides relatively with the side wall of the vertical rod 3.

[0025] The inner side wall of the limiting sliding hole 16 slides relative to the side wall of the vertical rod 3 to limit the movement trajectory of the plate body 5 so that it can only move up and down and avoid rotating with the external threaded tube 15.

[0026] When the whole needs to be moved, the external threaded tube 15 can be rotated (the external threaded tube 15 can only rotate relative to the vertical rod 3, and cannot move up and down, which is equivalent to the lead screw moving away) to move the plate body 5 upward and off the ground.

[0027] Specifically, the crossbar 2 may be a hydraulic cylinder.

[0028] The supporting position of the grounding seat 4 can be conveniently adjusted by the hydraulic cylinder.

[0029] Specifically, both left and right ends of the inner wall of the external threaded tube 15 are provided with slide grooves 17 , and both left and right ends of the side wall of the screw rod 10 are integrally formed with sliders 18 , and the two sliders 18 are slidably installed in the two slide grooves 17 respectively.

[0030] The slider 18 is slidably installed in the slide groove 17, so that the screw rod 10 rotates and the external threaded tube 15 is driven to rotate together through the slider 18, so that the universal wheel 11 moves downward and the plate body 5 moves upward, which is more convenient for operation. When the screw rod 10 drives the universal wheel 11 to move downward, the slider 18 will also slide downward in the slide groove 17.

[0031] Specifically, the side wall of the screw 10 does not contact the inner side wall of the externally threaded tube 15 .

[0032] Specifically, the externally threaded tube 15 includes a tube body 19 and a ring body 20 . The bottom of the ring body 20 is fixedly mounted on the top of the tube body 19 . The slide grooves 17 are arranged on the left and right ends of the inner wall of the tube body 19 .

[0033] Specifically, the inner top wall of the slide groove 17 is the bottom of the ring body 20 .

[0034] By dividing the externally threaded tube 15 into the tube body 19 and the ring body 20 , it is convenient to open the slide groove 17 at the top of the tube body 19 in the early stage, and it is also convenient to install the slider 18 in the externally threaded tube 15 .

[0035] Working principle: When in use, it can be supported on the ground through the bottom of the grounding seat 4 (plate body 5). At this time, the universal wheel 11 is retracted into the installation groove 6, which increases the overall anti-rollover performance and prevents the universal wheel 11 from being damaged by long-term contact with the ground. When the whole needs to be moved, the screw 10 can be rotated to drive the universal wheel 11 to move downward, and supported on the ground by the universal wheel 11. At the same time, the rotation of the screw 10 will also drive the external threaded tube 15 to rotate together through the slider 18, and the external threaded tube 15 will drive the plate body 5 to move upward and leave the ground.
