[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] Please see Figures 1-4 The present invention provides the following technical solution: a large vehicle stop device for port machinery maintenance, including a base 1, and further including: a flip plate 2, a drive mechanism 3, a sliding plate 4, a clamping mechanism 5, and an adjustment mechanism 7.

[0050] Furthermore, by Figure 1As shown, in this embodiment, the flip plate 2 is rotatably disposed on the top surface of the base 1, and the drive mechanism 3 is droopably connected to the flip plate 2 for driving the flip plate 2 to flip. The flip plate 2 has a guide notch 21, and the slide plate 4 is movably disposed within the guide notch 21. The clamping mechanism 5 is mounted on the slide plate 4 for clamping the wheel. The adjusting mechanism 7 is used to adjust the initial height of the slide plate 4, and the adjusting mechanism 7 includes a top plate 71, a threaded screw 72, and a handle 73. The top plate 71 is fixed to the free end of the flip plate 2, the threaded screw 72 is mounted on the top plate 71 by threaded engagement, and the bottom end of the threaded screw 72 is rotatably connected to the slide plate 4 using a bearing. The handle 73 is fixed to the top end of the threaded screw 72. With the above solution, two sets of phases are needed to fix one wheel during use. The symmetrically distributed stop devices allow for the anchoring of two sets of stop devices to the ground on the front and rear sides of the wheel. Then, the drive mechanism 3 is activated to rotate the tilting plate 2, tilting it beyond the vertical position. Depending on the wheel size, the screw 72 is rotated via the handle 73, causing the screw 72 to move the slide plate 4 through the screw thread. This adjusts the height of the clamping mechanism 5, ensuring it is positioned at or above the center of the wheel. Finally, the clamping mechanisms 5 on both sides clamp the wheel, ensuring its stability, preventing accidental movement, and ensuring the safety of maintenance work. This invention, through the adjustable mechanism 7, can adjust the initial height of the clamping mechanism 5, reliably clamping wheels of different sizes, improving stability, and broadening its applicability.

[0051] It is worth further explaining that the flip plate 2 can be flipped by the drive mechanism 3, and the tilt angle of the flip plate 2 can be adjusted for easy use and folding and storage.

[0052] In addition, when in use, the flip plate 2 is flipped to a position beyond the vertical position, which means that the flip plate 2 is tilted towards the wheel side. From a physics point of view, the flip plate 2 has higher stability in this state and is less likely to be accidentally flipped or bent and damaged, similar to a common inclined support mechanical structure.

[0053] Preferably, by Figure 1 As shown in this embodiment, the adjustment mechanism 7 further includes: guide posts 74. Two guide posts 74 are symmetrically fixed between the inner bottom surface of the guide notch 21 and the top plate 71, and the guide posts 74 penetrate the slide plate 4. With the above solution, when in use, the two guide posts 74 are used to guide the slide plate 4, which improves the stability of the slide plate 4. They are also used to limit the slide plate 4 and prevent the slide plate 4 from moving in the opposite direction under strong clamping force.

[0054] Optionally, by Figure 1 and Figure 2As shown in this embodiment, the clamping mechanism 5 includes: a clamping plate 51, a first hydraulic cylinder 52, and a rubber anti-slip pad 53. The clamping plate 51 has an arc-shaped clamping groove 511. The first hydraulic cylinder 52 is fixed on the slide plate 4, and the piston rod of the first hydraulic cylinder 52 passes through the slide plate 4 and is fixedly connected to the clamping plate 51. The rubber anti-slip pad 53 is bonded and fixed to the inner wall of the arc-shaped clamping groove 511. With the above solution, when in use, the first hydraulic cylinder 52 is started, and the piston rod of the first hydraulic cylinder 52 pushes the clamping plate 51 to move, so that the wheel can be clamped by the clamping plates 51 on both sides and the wheel can be fixed. The rubber anti-slip pad 53 has an anti-slip effect, which further improves the stability.

[0055] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, the clamping mechanism 5 further includes a first guide rod 54. Two sets of first guide rods 54 are symmetrically fixed to the outer wall of the clamping plate 51, and the first guide rods 54 penetrate the slide plate 4. With the above scheme, when in use, the two sets of first guide rods 54 are used to guide the clamping plate 51, which improves the stability of the clamping plate 51.

[0056] Preferably, by Figure 1 and Figure 3 As shown, this embodiment also includes an auxiliary support mechanism 6. The auxiliary support mechanism 6 is set on the flip plate 2 and located below the clamping mechanism 5. The auxiliary support mechanism 6 includes a U-shaped frame 61, a support roller 62, and a second hydraulic cylinder 63. The U-shaped frame 61 is located on one side of the flip plate 2. The support roller 62 is rotatably installed inside the U-shaped frame 61. The second hydraulic cylinder 63 is fixed on the flip plate 2, and the piston rod of the second hydraulic cylinder 63 passes through the flip plate 2 and is fixedly connected to the U-shaped frame 61. With the above solution, when the clamping plate 51 clamps the wheel, the second hydraulic cylinder 63 is activated. The piston rod of the second hydraulic cylinder 63 pushes the U-shaped frame 61 to move, and the support roller 62 supports the wheel from below, further improving the stability of the wheel. Even if the clamping plate 51 is locked ineffective due to strong winds, the vehicle body will not move. On the one hand, the support roller 62 prevents the vehicle from moving. On the other hand, the kinetic energy of the vehicle rotation will be completely converted into the kinetic energy of the support roller 62 rotation. Therefore, the vehicle will not move.

[0057] Preferably, by Figure 1 and Figure 3 As shown in this embodiment, the auxiliary support mechanism 6 further includes: a second guide rod 64. The two second guide rods 64 are symmetrically fixed to the outer wall of the U-shaped frame 61, and the second guide rods 64 penetrate the flip plate 2. With the above solution, the two second guide rods 64 are used to guide the U-shaped frame 61 during use, which improves the stability of the U-shaped frame 61.

[0058] Optionally, by Figure 1 and Figure 4 As shown, in this embodiment, the drive mechanism 3 includes: a first mounting ear 31 with a hole, a fixed shaft 32, a worm gear 33, a second mounting ear 34 with a hole, a worm 35, and a drive motor 36. The two first mounting ears 31 with holes are symmetrically fixed to the top surface of the base 1. The fixed shaft 32 is fixed to the end of the flip plate 2 and passes through the first mounting ear 31 with a hole to form a rotating structure. The worm gear 33 is fixed on the fixed shaft 32. The two second mounting ears 34 with holes are symmetrically fixed to the outer wall of the first mounting ear 31 with a hole. The worm 35 is rotatably installed between the two second mounting ears 34 with holes and meshes with the worm gear 33. The drive motor 36 is fixed on the second mounting ear 34 with a hole and is used to drive the worm 35 to rotate. With the above scheme, when in use, the drive motor 36 is started to drive the worm 35 to rotate. The worm 35 drives the worm gear 33 to rotate through the meshing action. The worm gear 33 drives the flip plate 2 to flip using the fixed shaft 32.

[0059] It should be noted that the above solution is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The worm gear 33 and the worm 35 have reverse self-locking characteristics, so the flip plate 2 will not rotate when the drive motor 36 is not started, and has high stability.

[0060] Preferably, by Figure 1 As shown, this embodiment also includes two sets of symmetrically distributed flexible inclined support mechanisms 8, and the flexible inclined support mechanism 8 includes: a telescopic rod 81, a limiting plate 82, and a telescopic spring 83. The bottom end of the telescopic rod 81 is hinged to the base 1, and the top end is hinged to the flip plate 2. Limiting plates 82 are fixed at both ends of the telescopic rod 81. The telescopic spring 83 is sleeved on the telescopic rod 81 and is located between the two limiting plates 82. The telescopic rod 81 is a telescopic structure composed of two hollow cylindrical components sleeved together. Through the setting of the telescopic spring 83, the flip plate 2 plays a flexible support function, which can offset part of the shaking of the flip plate 2 caused by strong winds and further improve stability.

[0061] It should be noted that the drive motor 36, hydraulic cylinder 52, and hydraulic cylinder 63 are all commercially available conventional equipment with built-in power switches. Those skilled in the art can make conventional selections according to their needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated on further in this article.

[0062] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0063] Components not described in detail in this article are existing technologies.

[0064] The working principle and usage process of this utility model: When using the stopping device of this utility model, two sets of symmetrically distributed stopping devices are needed to fix a wheel. Therefore, the two sets of stopping devices are anchored to the ground on the front and rear sides of the wheel respectively.

[0065] Then, the drive motor 36 is started to drive the worm 35 to rotate. The worm 35 drives the worm wheel 33 to rotate through meshing. The worm wheel 33 drives the flip plate 2 to flip through the fixed shaft 32, so that the flip plate 2 flips to a position beyond the vertical position.

[0066] For the size of the wheel, the screw 72 is rotated by the handle 73, so that the screw 72 drives the slide plate 4 to move under the screw engagement, thereby adjusting the height of the clamping mechanism 5 to ensure that the clamping mechanism 5 is positioned at or above the middle of the wheel.

[0067] Finally, start hydraulic cylinder 52. The piston rod of hydraulic cylinder 52 pushes clamping plate 51 to move, so that the wheel can be clamped by clamping plates 51 on both sides to fix the wheel, ensure the stability of the wheel, prevent the wheel from moving accidentally, and ensure the safety of maintenance work.

[0068] After clamping the wheel with clamp 51, start hydraulic cylinder 63. The piston rod of hydraulic cylinder 63 pushes U-shaped frame 61 to move. Support roller 62 supports the wheel from below, further improving the stability of the wheel. Even if strong winds cause clamp 51 to lock ineffectively, the vehicle body will not move.

[0069] The present invention uses an adjustment mechanism 7 to adjust the initial height of the clamping mechanism 5, which can reliably clamp wheels of different sizes, improve stability, and broaden the scope of application.

[0070] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
