Description
Technical Field
[0001] This utility model relates to the technical field of port trolley anchoring devices; more specifically, it relates to a port machinery trolley anchoring device. Background Technology
[0002] Port machinery refers to heavy machinery used in port operations, such as container cranes and gantry cranes, for loading and unloading cargo. The types, performance, and usage scenarios of these machines vary depending on the port's needs and the type of cargo.
[0003] Port machinery typically moves via rail. Since ports are near the sea and storms are frequent, anchoring devices are needed to secure the machinery. Anchoring devices clamp non-operating rail-mounted cranes to their designated stops along the rails to prevent them from accidentally sliding along the rails during storms.
[0004] Currently, existing port trolley anchoring devices typically connect to the trolley via clamping or squeezing during operation. However, this connection method may loosen in strong winds, reducing the stability of the equipment. Furthermore, prolonged exposure to the elements makes the equipment susceptible to corrosion or rust from rainwater immersion, affecting its performance and shortening its lifespan, thus diminishing its practicality. Therefore, there is an urgent need for a port trolley anchoring device to address these issues. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a port machinery trolley anchoring device to solve the problems existing in the background art.
[0006] This utility model provides the following technical solution: a port machinery trolley anchoring device, comprising: An anchoring base and a mounting circular plate are provided. The top surface of the anchoring base is fixedly connected to a connecting circular plate, and the connecting circular plate has a connecting structure inside. The mounting circular plate has a shielding structure inside, and an anchoring rod is inserted inside the shielding structure. The bottom end of the anchoring rod has a through groove. The connecting structure includes a movable groove, a connecting rod, and a mating groove, and the movable groove is opened inside the connecting circular plate. The shielding structure includes a sliding groove, and there are two sets of sliding grooves, which are respectively opened on both sides inside the mounting circular plate.
[0007] Preferably, the connection structure further includes a drive motor, which is installed on one side inside the movable slot. The output shaft of the drive motor is connected to a lead screw, and the outer surfaces of both ends of the lead screw are threaded with movable blocks. The top of the movable blocks is fixedly connected to a movable plate. A connecting rod is fixedly connected to one side of the outer surface of one set of movable plates, and a docking groove is opened inside the other set of movable plates. This design allows for the positioning of the anchor rod.
[0008] Preferably, the threads on the outer surfaces of both ends of the lead screw are designed with opposite threads, and the internal threads of the two sets of movable blocks respectively fitted on the outer surfaces of the lead screw are opposite to each other. This design allows the two sets of movable plates to move inward or outward synchronously.
[0009] Preferably, the external dimensions of the connecting rod are adapted to the internal dimensions of the through groove and the mating groove, which allows the connecting rod to be accurately inserted into the through groove and the mating groove.
[0010] Preferably, the shielding structure further includes a slider, and there are two sets of sliders. The two sets of sliders are respectively inserted into the interior of two sets of sliding grooves, and a rotating plate is fixedly connected to the side of the sliders that are close to each other. The rotating plate has a moving groove on both sides inside, and a moving block is inserted into the moving groove. The bottom end of the moving block is fixedly connected to a shielding plate. The top surface of the rotating plate is fixedly connected to both sides. This design can assist in clamping the anchor rod.
[0011] Preferably, the interior of the rotating plate begins with a limiting groove on one side of the moving groove, and the top of the moving block is fixedly connected to a limiting circular plate, and the external dimensions of the limiting circular plate are adapted to the internal dimensions of the limiting groove. This design allows the limiting circular plate to move stably inside the limiting groove.
[0012] Preferably, the internal dimensions of the moving slot are adapted to the external dimensions of the moving block, which allows the moving block to move smoothly inside the moving slot.
[0013] The technical effects and advantages of this utility model are as follows: By starting the drive motor, the lead screw is rotated, causing two sets of movable blocks to move synchronously inward along the outer surface of the lead screw, and moving two sets of movable plates accordingly, until the connecting rod passes through the through groove and the docking groove. Then the drive motor is stopped. This design allows the connecting rod to be inserted into the through groove and then snapped into the docking groove to perform the positioning and connection operation of the anchor rod. This connection method is relatively stable. In the event of strong winds, the anchor rod and the connecting circular plate can be stably connected, thereby improving the stability of the equipment to a certain extent. By rotating the operating lever, the rotating plate rotates inside the mounting plate. Under the action of the slider, the rotating plate can maintain stable rotation. During the rotation, the moving block moves along the inner wall of the moving groove, driving the two sets of baffles to move inward until the two baffles come into contact. Then, the operating lever is stopped. When not in use, this design allows the two sets of baffles to close, forming a shielding effect to prevent rainwater from dripping into the equipment, maintaining the equipment's effectiveness during use, and extending its service life. This improves the equipment's practicality to a certain extent. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The port trolley anchoring device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] Example 1, as Figure 1 and Figure 2 As shown, this embodiment proposes a port machinery trolley anchoring device, comprising: Anchor seat 1 and mounting circular plate 2, the top surface of anchor seat 1 is fixedly connected to connecting circular plate 3, and connecting structure 4 is provided inside connecting circular plate 3. Mounting circular plate 2 is provided inside shielding structure 5, and anchor rod 6 is inserted inside shielding structure 5. A through groove 7 is opened at the bottom of anchor rod 6. The connecting structure 4 includes a movable groove 41, a connecting rod 46, and a docking groove 47. The movable groove 41 is opened inside the connecting circular plate 3. The connecting structure 4 also includes a drive motor 42, which is installed on one side inside the movable groove 41. The output shaft of the drive motor 42 is connected to a lead screw 43 by a bearing. The outer surfaces of both ends of the lead screw 43 are threaded with movable blocks 44. The top of the movable blocks 44 is fixedly connected to a movable plate 45. One side of the outer surface of one set of movable plates 45 is fixedly connected to the connecting rod 46. The interior of the other set of movable plates 45 is provided with a docking groove 47. This design allows the anchor rod 6 to be positioned after the connecting rod 46 passes through the through groove 7 and the docking groove 47, thus completing the connection operation with the mechanical trolley. The threads on the outer surfaces of both ends of the lead screw 43 are designed with positive and negative threads. The two sets of movable blocks 44 are respectively fitted on the inner threads of the outer surface of the lead screw 43 with opposite threads. This design allows the two sets of movable blocks 44 to move synchronously inward or outward along the outer surface of the lead screw 43, so that the movable plate 45 moves accordingly, achieving the effect of closing the two sets of movable plates 45. The external dimensions of the connecting rod 46 are adapted to the internal dimensions of the through groove 7 and the docking groove 47. This design allows the connecting rod 46 to move stably inside the through groove 7 and the docking groove 47. After the connecting rod 46 is inserted into the through groove 7 and the docking groove 47, the position of the anchor rod 6 can be positioned.
[0021] The lead screw 43 in this application, as well as all movable parts, require regular cleaning and maintenance (including but not limited to dust removal and lubrication).
[0022] Example 2, as Figure 3 and Figure 4 As shown, based on the same concept as the above embodiments, this embodiment also proposes: The shielding structure 5 includes two sets of sliding grooves 51, which are respectively opened on both sides inside the mounting circular plate 2. The shielding structure 5 also includes two sets of sliding blocks 52, which are respectively inserted into the two sets of sliding grooves 51. A rotating plate 53 is fixedly connected to the side of the sliding blocks 52 that is close to each other. The rotating plate 53 has moving grooves 54 on both sides inside, and a moving block 55 is inserted into the moving groove 54. A shielding plate 56 is fixedly connected to the bottom end of the moving block 55. An operating rod 57 is fixedly connected to both sides of the top surface of the rotating plate 53. The two sets of moving... The interior of the groove 54 is all arc-shaped, and one end of the movable groove 54 is close to the center of the rotating plate 53, while the other end is far away from the center of the rotating plate 53. This design allows the movable groove 54 to move by rotating the rotating plate 53. The interior of the movable groove 54 is arc-shaped, and when the movable groove 54 moves, the movable block 55 can move along the inclined surface of the movable groove 54. After moving to a suitable position, the shielding plate 56 can move inward. When the two sets of shielding plates 56 come into contact, they can form a closed effect to block the rainwater from the outside and prevent the rainwater from entering the interior of the connecting structure 4. The rotating plate 53 has a limiting groove on one side of the moving groove 54. The top of the moving block 55 is fixedly connected to a limiting circular plate, and the external dimensions of the limiting circular plate are adapted to the internal dimensions of the limiting groove. The internal dimensions of the moving groove 54 are adapted to the external dimensions of the moving block 55. This design can limit the moving block 55, prevent the moving block 55 from leaving the inside of the moving groove 54, and at the same time allow the moving block 55 to move smoothly along the inside of the moving groove 54.
[0023] Working principle: When using the equipment, first move the mechanical trolley to the predetermined stopping position, then insert the anchoring rod 6 of the mechanical trolley into the pre-set anchoring groove until the bottom surface of the anchoring rod 6 contacts the top surface of the connecting circular plate 3. Then rotate the two sets of operating rods 57, causing the rotating plate 53 to rotate. At this time, the two sets of moving grooves 54 rotate accordingly, causing the two sets of moving blocks 55 to move along the inner wall of the moving groove 54, and driving the two sets of baffle plates 56 to move inward synchronously until the two sets of baffle plates 56 contact each other. Then stop rotating the operating rods 57. This design can provide simple guidance for the insertion position of the anchoring rod 6, so that the bottom surface of the anchoring rod 6 is properly inserted into the middle position of the top surface of the connecting circular plate 3. Then start the drive motor 42, which drives the lead screw 43 to rotate, so that the two sets of The movable block 44 moves inward synchronously along the outer surface of the lead screw 43, and drives the two sets of movable plates 45 to move accordingly. At this time, after the connecting rod 46 enters the interior of the through groove 7 and the docking groove 47, the drive motor 42 stops. This design can be used to connect the anchor rod 6, and this connection operation is relatively stable. It can firmly anchor the mechanical trolley even when encountering large winds and waves, preventing the mechanical trolley from shaking. When the mechanical trolley needs to be used, simply start the drive motor 42 in reverse, causing the lead screw 43 to rotate in the opposite direction. This causes the two sets of movable plates 45 to move away from each other until the connecting rod 46 disengages from the interior of the docking groove 47 and the through groove 7. This cancels the positioning effect of the anchor rod 6. Pulling the anchor rod 6 outward will cancel the anchoring effect, and the mechanical trolley can be used normally to complete port operations. After the equipment is used, first rotate the two sets of operating levers 57 to make the rotating plate 53 rotate inside the mounting circular plate 2. Under the action of the slider 52, the rotating plate 53 can maintain stable rotation inside the mounting circular plate 2. During the rotation, the moving groove 54 will move along the outer surface of the moving block 55. The inside of the moving groove 54 is arc-shaped, with one end close to the center of the rotating plate 53 and the other end far away from the center of the rotating plate 53. When the moving block 55 is close to the position inside the moving groove 54 with one end close to the rotating plate 53, the moving block 55 can be closer to the center of the rotating plate 53. At this time, it can drive the two sets of baffles 56 to move inward synchronously until the two sets of baffles 56 abut against each other. Then stop rotating the operating levers 57. This design can By controlling the moving distance between the two sets of shielding plates 56, and when the two sets of shielding plates 56 abut against each other, the surface of the rotating plate 53 can be sealed to prevent outdoor rainwater or impurities from entering the interior of the connecting structure 4. At the same time, before use, a small amount of impurities and rainwater may remain on the surface of the shielding plate 56. At this time, the staff needs to clean it briefly to ensure that the surface of the shielding plate 56 is clean. Then, the operating lever 57 is rotated in the opposite direction. When it is rotated to the appropriate position, the moving block 55 is located at the end of the moving groove 54 away from the center of the rotating plate 53. This allows the two sets of shielding plates 56 to move outward synchronously, so that there is enough space in the middle of the rotating plate 53 to facilitate the insertion of the anchoring rod 6. The above is the complete working principle of this utility model.
