Description

Technical Field

[0001] This utility model relates to the field of anchoring technology, and more specifically, to an anchoring structure for a gantry crane. Background Technology

[0002] Current technologies for gantry crane anchoring structures have certain shortcomings. First, on soft soil, slippery or uneven ground, the anchor plate may not provide sufficient support, causing the crane to tilt or become unstable, increasing the risk of accidents during operation. Second, replacing the anchor plate is a major challenge in current gantry crane anchoring structures. In existing designs, the anchor plate is usually tightly integrated with the anchoring system, and the installation and disassembly process is relatively complex. Replacing the anchor plate requires significant time and labor, and specialized equipment and tools.

[0003] Even more serious is that existing anchoring structures often lack adaptability to extreme ground conditions. For example, in extreme high or low temperatures or sandstorms, the materials and designs of traditional anchoring structures may not be able to cope with rapid changes in ground conditions, resulting in poor anchoring performance. In addition, if there are significant changes in the ground, existing anchoring systems cannot effectively adjust pressure distribution or quickly replace anchor plates, which will greatly reduce the reliability and safety of gantry cranes in these special environments.

[0005] To address the problems existing in the prior art, this utility model provides an anchoring structure for a gantry crane, which solves the technical problems mentioned in the background art, such as unstable anchoring process and difficulty in replacing anchoring plates, resulting in poor adaptability to extreme ground conditions.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a gantry crane anchoring structure, comprising a base, a hydraulic anchoring mechanism, an anchor plate clamping mechanism, and a clamping auxiliary mechanism.

The connecting frame is installed at one end of the support arm, one end of the hydraulic cylinder is rotatably connected to the connecting frame, the rotating frame is rotatably installed at one end of the support arm, and the other end of the hydraulic cylinder is rotatably connected to the rotating frame. The rotating rod is fitted at one end of the rotating frame, and the anchoring plate is installed at the bottom of the rotating rod. The anchor plate clamping mechanism includes a clamping tube, a clamping rod, a clamping groove, a transverse rod, a slope plate, a rotating block, and a slope groove. The clamping rod can extend into the interior of the clamping tube, the clamping groove is provided on the side wall of the clamping rod, the transverse rod is laterally slidably installed on the side wall of the clamping tube, the slope plate is installed at one end of the transverse rod, multiple sets of rotating blocks are limited and rotatably installed on the outer wall of the clamping tube, and the slope groove is provided on the rotating block. The slope plate and the slope groove are rotatably slidably connected.

[0008] The present invention is further configured such that the snap-fit ​​auxiliary mechanism includes a threaded ring, a directional ring, a slope pusher block, and an elastic support plate. The threaded ring is threadedly connected to the outer wall of the snap-fit ​​tube, and the directional ring is slidably disposed on the outer wall of the snap-fit ​​tube. The threaded ring can push the directional ring to move in a directional manner. The slope pusher block is installed at the top end of the directional ring, and the elastic support plate is installed between adjacent rotating blocks, so that the transverse rod extends into the snap-fit ​​groove. The slope pusher block can push the two rotating blocks to move in opposite directions, so that the slope groove rotates and the transverse rod moves away from the snap-fit ​​groove.

[0009] The present invention is further configured such that a guide wheel assembly is installed at the bottom of the base, and the guide wheel assembly is fitted on an external slide rail. The guide wheel assembly can effectively cooperate with the external slide rail to ensure that the crane moves more smoothly and improves the mobility of the equipment.

[0011] The present invention is further configured such that an upper connecting plate is installed at the top of the side wall of the clamping pipe, and an upper connecting rod is installed at the top end of the upper connecting plate. The upper connecting rod is rotatably installed at one end of the rotating rod. The design of the upper connecting plate and the upper connecting rod makes the clamping structure more secure. The rotatable installation of the upper connecting rod at one end of the rotating rod allows the anchoring plate to be adjusted more flexibly at different angles, thereby improving the adaptability of the system.

[0012] The present invention is further configured such that a connecting plate is installed at one end of the snap-fit ​​rod, and the bottom end of the connecting plate is connected to the anchor plate. The anchor plate is in contact with the ground for support. The connection plate facilitates a stable connection between the snap-fit ​​rod and the anchor plate.

[0013] The present invention is further configured such that a thrust bearing is installed on the top of the threaded ring, and the bottom end of the directional ring is in contact with the top end of the thrust bearing.

[0014] The present invention is further configured such that the bases can be arranged in pairs, and the bottom ends of the external gantry crane are connected to the top end of the bases. The pairing of the bases and their connection to the bottom of the external gantry crane can increase the stability of the overall structure.

[0029] Please see Figures 1-5 An anchoring structure for a gantry crane includes a base 1, a hydraulic anchoring mechanism, an anchor plate locking mechanism, and a locking auxiliary mechanism. The hydraulic anchoring mechanism includes a hydraulic cylinder 2, a support arm 3, a connecting frame 4, a rotating frame 5, a rotating rod 6, and an anchoring plate 7. The connecting frame 4 is installed at one end of the support arm 3. One end of the hydraulic cylinder 2 is rotatably connected to the connecting frame 4. The rotating frame 5 is rotatably installed at one end of the support arm 3, and the other end of the hydraulic cylinder 2 is rotatably connected to the rotating frame 5. The rotating rod 6 is fitted onto one end of the rotating frame 5, and the anchoring plate 7 is installed on the rotating rod 6. At the bottom, the anchor plate snap-fit ​​mechanism includes a snap-fit ​​tube 8, a snap-fit ​​rod 9, a snap-fit ​​groove 10, a transverse rod 11, a slope plate 12, a rotating block 13, and a slope groove 14. The snap-fit ​​rod 9 can extend into the interior of the snap-fit ​​tube 8. The snap-fit ​​groove 10 is set on the side wall of the snap-fit ​​rod 9. The transverse rod 11 is slidably mounted on the side wall of the snap-fit ​​tube 8. The slope plate 12 is mounted on one end of the transverse rod 11. Multiple sets of rotating blocks 13 are rotatably mounted on the outer wall of the snap-fit ​​tube 8. The slope groove 14 is set on the rotating block 13. The slope plate 12 and the slope groove 14 are rotatably and slidably connected.

[0030] In this embodiment, hydraulic cylinder 2 is activated. One end of hydraulic cylinder 2 is rotatably connected to connecting frame 4, and the other end is rotatably connected to rotating frame 5. As hydraulic cylinder 2 extends, rotating frame 5 rotates around one end of support arm 3, causing rotating rod 6 to move downward. When rotating rod 6 moves downward, anchor plate 7 gradually approaches the ground. When hydraulic cylinder 2 extends, anchor plate 7 contacts the ground and applies a certain pressure, thereby achieving anchoring of the gantry crane. Hydraulic cylinder 2 remains extended, and anchor plate 7 is firmly fixed to the ground, ensuring the gantry crane is anchored. To ensure the stability of the crane during operation, the locking rod 9 is inserted into the locking tube 8. The locking groove 10 on the locking rod 9 is aligned with the transverse rod 11 on the side wall of the locking tube 8. The locking auxiliary mechanism is used to make the transverse rod 11 slide laterally on the side wall of the locking tube 8 until it enters the locking groove 10. The slope plate 12 contacts the slope groove 14. Guided by the slope groove 14, the transverse rod 11 is more firmly locked into the locking groove 10. The locking rod 9 is firmly fixed in the locking tube 8, ensuring that the anchoring plate 7 will not loosen during the anchoring process.

[0031] The snap-fit ​​auxiliary mechanism includes a threaded ring 15, a directional ring 16, a slope pusher 17, and an elastic support plate 18. The threaded ring 15 is threadedly connected to the outer wall of the snap-fit ​​tube 8. The directional ring 16 is slidably disposed on the outer wall of the snap-fit ​​tube 8. The threaded ring 15 can push the directional ring 16 to move in a directional manner. The slope pusher 17 is installed at the top end of the directional ring 16. The elastic support plate 18 is installed between adjacent rotating blocks 13, so that the transverse rod 11 extends into the snap-fit ​​groove 10. The slope pusher 17 can push the two rotating blocks 13 to move in opposite directions, so that the slope groove 14 rotates and the transverse rod 11 moves away from the snap-fit ​​groove 10.

[0032] In this embodiment, the threaded ring 15 is rotated and moves longitudinally along the outer wall of the retaining tube 8. The threaded ring 15 pushes the directional ring 16 to move, and the directional ring 16 slides directionally on the outer wall of the retaining tube 8. The slope push block 17 moves accordingly and pushes the two rotating blocks 13 to move in opposite directions. The slope groove 14 on the rotating block 13 separates from the slope plate 12, so that the transverse rod 11 moves away from the retaining groove 10, thereby releasing the fixation of the retaining rod 9. Conversely, the elastic support plate 18 pushes the rotating blocks 13 to move towards each other, so that the transverse rod 11 extends into the retaining groove 10.

[0033] Please see Figures 1-5As a supplementary embodiment of the anchoring structure for a gantry crane, which includes a hydraulic anchoring mechanism, an anchor plate clamping mechanism, and a clamping auxiliary mechanism: A guide wheel assembly 19 is installed at the bottom of the base 1, and the guide wheel assembly 19 is fitted onto an external slide rail. An installation block 20 is installed on the side of the base 1, and a connecting frame 4 is fitted onto the installation block 20. An upper connecting plate 21 is installed at the top of the side wall of the clamping pipe 8, and an upper connecting rod 22 is installed at the top end of the upper connecting plate 21. The upper connecting rod 22 is rotatably installed at one end of the rotating rod 6. A connecting plate 23 is installed at one end of the clamping rod 9, and the bottom end of the connecting plate 23 is connected to the anchoring plate 7. The anchoring plate 7 is in contact with the ground for support. A thrust bearing 24 is installed at the top of the threaded ring 15, and the bottom end of the directional ring 16 is in contact with the top end of the thrust bearing 24. The bases 1 can be installed in pairs, and the bottom ends of the external gantry cranes are connected to the top ends of the bases 1.

[0034] More specifically, when anchoring the gantry crane is required, hydraulic cylinder 2 is activated, extending and driving the rotating frame 5 and rotating rod 6 downwards, causing the anchoring plate 7 to contact the ground and apply pressure, thus achieving anchoring. The locking rod 9 is inserted into the locking tube 8, and the transverse rod 11 slides into the locking groove 10. Through the cooperation of the slope plate 12 and slope groove 14, the locking rod 9 is securely fixed in the locking tube 8, and the transverse rod 11 is securely locked in the locking groove 10. The gantry crane is firmly anchored to the ground, ensuring stability during operation. When the anchoring plate 7 needs to be replaced under different ground conditions, the threaded ring 15 is rotated in the opposite direction, causing the directional ring 16 and slope push block 17 to move upwards, pushing the rotating block 13 to move in opposite directions, causing the transverse rod 11 to disengage from the locking groove 10. The locking rod 9 is then pulled out of the locking tube 8, and hydraulic cylinder 2 retracts, driving the rotating frame 5 and rotating rod 6 upwards, causing the anchoring plate 7 to leave the ground.

[0035] In summary, during the use or operation of the overall equipment: when the hydraulic anchoring mechanism is required, the hydraulic cylinder 2 is activated. One end of the hydraulic cylinder 2 is rotatably connected to the connecting frame 4, and the other end is rotatably connected to the rotating frame 5. As the hydraulic cylinder 2 extends, the rotating frame 5 rotates around one end of the support arm 3, causing the rotating rod 6 to move downward. When the rotating rod 6 moves downward, the anchoring plate 7 gradually approaches the ground. When the hydraulic cylinder 2 extends, the anchoring plate 7 contacts the ground and applies a certain pressure, thereby achieving the anchoring of the gantry crane. The hydraulic cylinder 2 remains in the extended state, and the anchoring plate 7 is firmly fixed to the ground, ensuring the stability of the gantry crane during operation.

[0036] When the anchor plate snap-fit ​​mechanism is in operation, it enables the quick installation and removal of the anchor plate 7, allowing for rapid replacement of the anchor plate 7 and adapting to more working conditions. When it is necessary to fix the anchor plate 7, the snap-fit ​​rod 9 is inserted into the snap-fit ​​tube 8. The snap-fit ​​groove 10 on the snap-fit ​​rod 9 is aligned with the transverse rod 11 on the side wall of the snap-fit ​​tube 8. The snap-fit ​​auxiliary mechanism is used to make the transverse rod 11 slide laterally on the side wall of the snap-fit ​​tube 8 until it enters the snap-fit ​​groove 10. The slope plate 12 contacts the slope groove 14. Guided by the slope groove 14, the transverse rod 11 is more firmly snapped into the snap-fit ​​groove 10. The snap-fit ​​rod 9 is firmly fixed in the snap-fit ​​tube 8, ensuring that the anchor plate 7 will not loosen during the anchoring process.

[0037] When the locking auxiliary mechanism is in operation, the threaded ring 15 is rotated, and the threaded ring 15 moves longitudinally along the outer wall of the locking tube 8. The threaded ring 15 pushes the directional ring 16 to move, and the directional ring 16 slides in a direction on the outer wall of the locking tube 8. The slope push block 17 moves accordingly, and the slope push block 17 pushes the two rotating blocks 13 to move in opposite directions. The slope groove 14 on the rotating block 13 separates from the slope plate 12, so that the transverse rod 11 moves away from the locking groove 10, thereby releasing the locking rod 9 from being fixed. Conversely, the elastic support plate 18 pushes the rotating blocks 13 to move towards each other, so that the transverse rod 11 extends into the locking groove 10.

[0038] Hydraulic cylinder 2 is activated, extending and driving the rotating frame 5 and rotating rod 6 downwards, bringing the anchoring plate 7 into contact with the ground and applying pressure to achieve anchoring. The locking rod 9 is inserted into the locking tube 8, and the transverse rod 11 slides into the locking groove 10. Through the cooperation of the slope plate 12 and slope groove 14, the locking rod 9 is securely fixed in the locking tube 8, and the transverse rod 11 is securely locked in the locking groove 10. The gantry crane is firmly anchored to the ground, ensuring stability during operation. When the anchoring plate 7 needs to be replaced under different ground conditions, the threaded ring 15 is rotated in the opposite direction, causing the directional ring 16 and slope push block 17 to move upwards, pushing the rotating block 13 to move in opposite directions. This causes the transverse rod 11 to disengage from the locking groove 10, the locking rod 9 to be pulled out of the locking tube 8, and the hydraulic cylinder 2 retracts, driving the rotating frame 5 and rotating rod 6 upwards, lifting the anchoring plate 7 off the ground.

[0039] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
