Description

Technical Field

[0001] This utility model belongs to the field of port machinery technology, and in particular relates to a port machinery trolley anchoring device. Background Technology

[0002] Port machinery refers to large equipment used in port operations for loading and unloading cargo or transporting containers, such as port cranes, forklifts, and quay cranes.

[0003] To prevent port machinery trolleys from moving when not in operation, anchoring devices are typically used for locking. For example, an anchoring device for port machinery trolleys disclosed in application number CN2021229412433 includes an anchoring seat with an anchoring hole at the top. A first anchoring post is inserted into the anchoring hole. A groove is provided on the upper side of the first anchoring post, and a sliding plate is slidably arranged inside the groove. A buffer spring and a connecting post are connected to the top of the sliding plate. The top of the connecting post extends to the upper side of the first anchoring post and is fixedly connected to a second anchoring post. A first rotating rod is rotatably connected to the right end of the second anchoring post. A first square groove is provided inside the second anchoring post. A first bevel gear is fixedly connected to one end of the first rotating rod that extends into the first square groove. A second bevel gear that meshes with the first bevel gear is provided on the lower side of the first square groove.

[0004] Although the above technical solution can ensure the dryness of the inside of the anchoring hole, prevent it from being eroded by rainwater, and extend its service life, the anchoring post is decomposed into multiple components such as the first anchoring post, the second anchoring post, the sliding plate, and the connecting post. This not only leads to structural complexity but also reduces the tensile strength of the anchoring post. Utility Model Content

[0031] Example 1: As Figures 1 to 3 As shown, a port machinery trolley anchoring device includes an anchoring seat 1. The upper end of the anchoring seat 1 is provided with an anchoring hole 11 and an anchoring post 2. The anchoring post 2 is inserted into the anchoring hole 11. The side of the anchoring hole 11 is provided with multiple grooves 111 distributed circumferentially. Multiple sliders 21 are fixedly provided on the side of the anchoring post 2, with each slider 21 corresponding to one of the grooves 111. The sliders 21 slide up and down in cooperation with their corresponding grooves 111. The anchoring seat 1 is provided with a driving assembly 3 for driving all the sliders 21 to slide up and down. The side of the anchoring post 2 is provided with a through hole 22, which serves as a traction ring. Preferably, the anchoring post 2 and the sliders 21 are integrally formed, resulting in better structural strength and helping to ensure tensile strength.

[0032] In this embodiment, the inner wall of the anchoring hole 11 is provided with two second annular grooves 112, and a waterproof sealing ring 113 is provided in the second annular groove 112. The anchoring hole 11 is waterproofly sealed with the anchoring column 2 through the waterproof sealing ring 113, preventing rainwater from seeping into the interior of the anchoring seat 1, and ultimately extending the service life of this anchoring device.

[0033] When not in use, such as Figure 1As shown, the anchor post 2 moves down and is completely retracted into the anchor hole 11, at which point the through hole 22 is located between the two waterproof sealing rings 113; in use, as... Figure 4 As shown, the anchor post 2 moves upward and partially extends out of the anchor hole 11. At this time, the through hole 22 is located above the anchor seat 1, and the slider 21 abuts against the upper inner wall of the slide groove 111.

[0034] In this embodiment, the anchoring seat 1 includes an upper seat body 12 and a lower seat body 13. Anchoring holes 11, anchoring posts 2, sliding grooves 111, and driving components 3 are all disposed on the upper seat body 12. The lower ends of the anchoring holes 11 and the sliding grooves 111 penetrate the lower end face of the upper seat body 12. The upper end face of the lower seat body 13 is fixedly connected to the lower end face of the upper seat body 12, and the lower seat body 13 closes the lower ends of the anchoring holes 11 and the sliding grooves 111. It should be noted that the upper seat body 12 and the lower seat body 13 are processed separately for component assembly, and then finally welded together.

[0035] Example 2: Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the rest is the same as in Embodiment 1, except that the upper end of the anchoring seat 1 is provided with a first annular groove 14 and an annular sealing cover 15. The first annular groove 14 surrounds the anchoring hole 11. The inner wall of the sliding groove 111 is connected to the bottom of the first annular groove 14. The driving assembly 3 is disposed in the first annular groove 14. The annular sealing cover 15 covers the opening of the first annular groove 14. The annular sealing cover 15 is used to close the first annular groove 14 to prevent rainwater from seeping into the interior of the anchoring seat 1, thereby extending the service life of the anchoring device.

[0036] In this embodiment, the drive assembly 3 includes an annular plate 31, an external gear ring 32, and multiple screws 33. A first screw hole 211 is provided on the slider 21. The annular plate 31 is detachably disposed at the bottom of the first annular groove 14. Multiple first through holes 311 are provided on the annular plate 31, each corresponding to and communicating with multiple sliding grooves 111. Multiple screws 33 correspond to multiple first through holes 311, with the lower part of each screw 33 passing through the corresponding first through hole 311 and extending into the sliding groove 111. Screws 33 within the same sliding groove 111 are threadedly connected to the first screw hole 211. A gear 34 is fixedly disposed at the upper end of each screw 33. The external gear ring 32 is located at the upper end of the annular plate 31 and meshes with all gears 34. The inner ring of the external gear ring 32 contacts the inner sidewall of the first annular groove 14. Rotating one gear 34 drives the other gears 34 to rotate synchronously via the external gear ring 32, achieving smooth transmission.

[0037] In this embodiment, the upper end of the gear 34 is provided with a cross-shaped groove or a straight groove, preferably a cross-shaped groove.

[0038] In use, open the annular sealing cover 15 and rotate one gear 34 to drive the screw 33 and the external gear ring 32 connected to it to rotate. The external gear ring 32 then drives the other gears 34 to rotate, so that all the screws 33 rotate synchronously, and finally drive the slider 21 and the anchor post 2 connected to the slider 21 to move smoothly up or down.

[0039] Example 3: Figure 7 and Figure 8 As shown, the rest of the parts are the same as in Embodiment 2. The difference is that the bottom of the first annular groove 14 is provided with a plurality of second screw holes (not shown in the figure) distributed along the circumferential direction, and the annular plate 31 is provided with a plurality of second through holes 312. The plurality of second through holes 312 correspond one-to-one with the plurality of second screw holes. After the bolt 4 passes through the second through hole 312, it is threadedly connected to the second screw hole. The structure is simple and easy to disassemble and assemble.

[0040] In this embodiment, a limiting member 35 is provided at the upper end of the annular plate 31. The limiting member 35 presses against the upper end surface of the external gear ring 32, which helps to improve the stability of the fit between the components.

[0041] Example 4: Figure 7 and Figure 8 As shown, the rest is the same as in Embodiment 3, except that the limiting member 35 includes a first folded edge 351, a second folded edge 352 and a third folded edge 353 connected in sequence. The lower end face of the first folded edge 351 abuts against the upper end face of the annular plate 31. A third through hole 3511 is provided on the first folded edge 351. The bolt 4 passes through the third through hole 3511 and the second through hole 312 and is threadedly connected to the second screw hole. The lower end face of the third folded edge 353 abuts against the upper end face of the external gear ring 32. By using the bolt 4 to lock the annular plate 31 and the limiting member 35 at the same time, it helps to reduce the use of locking parts, simplify the assembly process and reduce costs.
