Description

Technical Field

[0001] This utility model relates to the field of crane technology, and specifically to an anchoring device. Background Technology

[0002] Gantry cranes are a type of bridge crane, also known as portal cranes. They are used for loading and unloading cargo and bulk materials in large ships or outdoor cargo yards and material yards. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability and strong versatility. They are widely used in port cargo yards. Gantry cranes are subjected to large wind loads in both working and non-working states, especially during typhoon season when they need to withstand extremely large wind loads. It is necessary for gantry cranes to be anchored after stopping to resist the wind loads.

[0003] For example, Chinese patent document No. 202420851298.6, published on January 7, 2025, discloses an anchoring device for a gantry crane, including a crane body and a rail. A mounting plate is provided on one side of the crane body, and an anchoring component is pivotally connected to the mounting plate. A connecting plate is provided on the side of the mounting plate, and one end of the connecting plate is pivotally connected to the mounting plate. The connecting plate and the anchoring component are connected by bolts. A first anchoring block is provided on the side wall of the rail, and a second anchoring block is provided on the ground on one side of the rail.

[0004] The aforementioned literature describes moving the crane body along the track to the position corresponding to the first or second anchoring block of the anchoring assembly. By pushing the anchoring rod to slide in the guide groove of the mounting block, the lower end of the anchoring rod is inserted into the first or second slot. Then, the anchoring rod is locked by the pawl engaging the ratchet teeth, thus achieving the anchoring action. The anchoring rod can only be locked by the cooperation of the pawl and ratchet teeth. When problems occur and disassembly and repair are required, other structures connected to the pawl and ratchet teeth also need to be considered, making the operation complicated. Utility Model Content

[0005] The purpose of this invention is to provide an anchoring device that can stably anchor a gantry crane and is easy to operate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anchoring device for fixing a gantry crane at a fixed point, comprising an anchoring cylinder, an anchoring support, and a locking assembly. The anchoring cylinder is fixed in the vertical direction of the gantry crane by a locking member. The anchoring support is located directly below the anchoring cylinder. A piston rod is movably connected to the anchoring cylinder. The piston rod includes a first piston rod and a second piston rod. The second piston rod has a second through hole. A first through hole is provided on a fixing plate located between the anchoring cylinder and the anchoring support. The second piston rod passes through the first through hole and a third through hole provided on the anchoring support in sequence, and then passes through to the bottom of the anchoring support. The locking assembly passes through from one side of the anchoring support to the other side of the anchoring support and locks the second piston rod.

[0007] The above configuration, with the piston rod extending vertically downwards, allows the second piston rod to pass sequentially through the first through hole on the fixed plate, the third through hole on the anchoring support, and through to the bottom of the anchoring support. By setting a fixed plate between the anchoring cylinder and the anchoring support, the distance between the anchoring support and the gantry crane can be reduced. Thus, after the second piston rod is locked to the bottom of the anchoring support by the locking assembly, the torque exerted by the gantry crane on the connection between the second piston rod and the locking assembly is reduced. This effectively reduces the bending moment exerted by the gantry crane on the connection between the second piston rod and the locking assembly, thereby enabling stable anchoring of the gantry crane. In other words, after anchoring, the bending moment resistance is further improved, and the service life of the entire anchoring structure is extended.

[0008] Furthermore, the anchoring cylinder is provided with a flange on its outer side, and the flange is provided with two or more fourth through holes.

[0009] The above settings facilitate the fixing of the anchoring cylinder onto the gantry crane after the locking component passes through the fourth through hole, and also ensure that the anchoring cylinder is set in a vertical direction.

[0010] Furthermore, the diameter of the second piston rod is larger than the diameter of the first piston rod.

[0011] The above settings increase the diameter of the second piston rod, which in turn increases the force that the second piston rod can withstand.

[0012] Furthermore, one end of the first piston rod is fixedly connected to one end of the second piston rod, and the other end of the second piston rod is provided with a second through hole. The length of the second piston rod is greater than the distance from the upper end face of the anchor support to the fixed plate fixed on the gantry crane.

[0013] With the above configuration, after the second piston rod passes through to the bottom of the anchor support and connects with the locking assembly, the second piston rod is positioned between the anchor support and the fixed plate, thereby giving the larger diameter second piston rod a greater bending moment resistance.

[0014] Furthermore, the diameter of the first through hole matches the diameter of the second piston rod.

[0015] The above settings facilitate the placement of the second piston rod through the fixed plate.

[0016] Furthermore, the bottom of the anchoring support is provided with two or more support plates, and two fixing parts are provided between the support plates. The fixing parts are provided with a fifth through hole arranged coaxially, and a third through hole is located between the fixing parts.

[0017] The above configuration allows the locking component to connect with the second piston rod after passing through the fifth through hole, thereby locking the second piston rod.

[0018] Furthermore, the locking assembly includes a locking pin and a locking plate. One end of the locking pin is provided with a limiting protrusion, and the limiting protrusion is provided with a countersunk hole. The locking plate is provided with two or more sixth through holes and seventh through holes. The seventh through holes are located on both sides of the sixth through holes. The end of the locking plate is recessed inward along the axial direction to form a receiving groove that matches the limiting protrusion. The sixth through hole communicates with the receiving groove.

[0019] With the above configuration, after the locking pin passes through the second through hole of the second piston rod, the locking plate can be placed on the limiting protrusion of the locking pin, so that the limiting protrusion is accommodated in the receiving groove. Then, the limiting protrusion and the locking plate are connected to form an integral unit by the locking member passing through the sixth through hole. At the same time, the locking plate can be fixed on the fixing part by the locking member passing through the seventh through hole, restricting the movement of the locking pin in the axial direction, thereby locking the second piston rod.

[0020] Furthermore, the diameter of the locking pin is matched with the diameter of the second through hole, and is smaller than the diameter of the fifth through hole.

[0021] With the above configuration, after the locking pin passes through the second through hole of the second piston rod, the anchoring cylinder can drive the second piston rod to move upward in the vertical direction, thereby driving the locking pin to move upward until the locking pin abuts against the inner wall of the fifth through hole and stops moving. At this time, the locking plate is fixed to the fixing part by the locking member passing through the seventh through hole, so as to achieve a stable connection between the locking assembly, the anchoring support, and the second piston rod.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-6 As shown, this utility model provides an anchoring device for fixing a gantry crane at a fixed point. It includes an anchoring cylinder 1, an anchoring support 2, and a locking assembly. The outer side of the anchoring cylinder 1 is provided with a flange 3, and the flange 3 is provided with two or more fourth through holes (not shown in the figure). After passing through the fourth through holes, the cylinder is fixed to the gantry crane 4 by a locking member, which is a bolt. The anchoring cylinder 1 fixed to the gantry crane 4 is arranged in a vertical direction. The anchoring support 2 is located directly below the anchoring cylinder 1. The anchoring cylinder 1 is movably connected to a piston rod, which includes a first piston rod 5 and a second piston rod 6 with a diameter larger than that of the first piston rod 5. One end of the first piston rod 5 and the second piston rod 6 are fixedly connected, and the other end of the second piston rod 6 is provided with a second through hole 7. In this embodiment, the anchoring cylinder 1 can drive the piston rod to perform a telescopic action under the drive of a hydraulic circuit that forms a complete circuit.

[0030] like Figure 1-3 As shown, a fixing plate 8 is provided between the anchoring cylinder 1 and the anchoring support 2. The fixing plate 8 is welded to the gantry crane 4 and has a first through hole. The diameter of the first through hole matches the diameter of the second piston rod 6. At the same time, the length of the second piston rod 6 is greater than the distance from the upper end face of the anchoring support 2 to the fixing plate 8 fixed on the gantry crane 4. Thus, when the second piston rod 6 passes through the first through hole and the third through hole 13 provided on the anchoring support 2 in sequence and then passes through to the bottom of the anchoring support 2, the second piston rod 6 can be positioned between the anchoring support 2 and the fixing plate 8. The locking component passes through from one side of the anchoring support 2 to the other side of the anchoring support 2 and locks the second piston rod 6, thereby giving the larger diameter second piston rod 6 a greater bending moment resistance.

[0031] like Figure 1 , 2 As shown in Figure 4, the anchoring support 2 is provided with a third through hole 13, and the bottom of the anchoring support 2 is provided with two or more support plates 9. Two fixing parts 10 are provided between the support plates 9. The fixing parts 10 are arranged perpendicularly to the support plates 9. The fixing parts 10 are provided with a fifth through hole 11 arranged coaxially. The third through hole 13 is located between the fixing parts 10, and the center of the third through hole 13 and the center of the fifth through hole 11 are in the same vertical plane. This allows the second piston rod 6 to pass through the third through hole 13 and penetrate between the two fixing parts 10 at the bottom of the anchoring support 2. Then, the locking assembly passes through the fifth through hole 11 and then passes through the second through hole 7 of the second piston rod 6 to connect with the second piston rod 6, thereby locking the second piston rod 6.

[0032] like Figure 5 and 6As shown, the locking assembly includes a locking pin 12 and a locking plate 14. One end of the locking pin 12 has a limiting protrusion 15 with a countersunk hole 16. The locking plate 14 has two or more sixth through holes 17 and seventh through holes 18. The sixth through holes 17 and the countersunk hole 16 are coaxially arranged, and the seventh through holes 18 are located on both sides of the sixth through holes 17. The end of the locking plate 14 is recessed inward along the axial direction to form a receiving groove 19 that matches the limiting protrusion 15. The sixth through holes 17 communicate with the receiving groove. After the locking pin 12 passes through the second through hole 7 of the second piston rod 6, the locking plate 14 can be placed on the limiting protrusion 15 of the locking pin 12, so that the limiting protrusion 15 is accommodated in the receiving groove 19. Then, the limiting protrusion 15 and the locking plate 14 are connected to form an integral unit by the locking member passing through the sixth through hole 17. At the same time, the locking plate 14 can be fixed on the fixing part 10 by the locking member passing through the seventh through hole 18, which restricts the movement of the locking pin 12 in the axial direction, thereby locking the second piston rod 6.

[0033] In this embodiment, the diameter of the locking pin 12 matches the diameter of the second through hole 7 and is smaller than the diameter of the fifth through hole 11. This way, after the locking pin 12 passes through the second through hole 7 of the second piston rod 6, the second piston rod 6 can be driven to move vertically upward by the anchoring cylinder 1, thereby driving the locking pin 12 to move upward until the locking pin 12 abuts against the inner sidewall of the fifth through hole 11 and stops moving. At this time, the locking plate 14 is fixed to the fixing part 10 by the locking member passing through the seventh through hole 18, so as to achieve a stable connection between the locking assembly, the anchoring support 2, and the second piston rod 6.

[0034] The working principle of this utility model is as follows: After the anchoring cylinder 1 drives the second piston rod 6 to extend downward in the vertical direction, the second piston rod 6 passes through the first through hole on the fixing plate 8 and the third through hole 13 on the anchoring support 2 in sequence, and then passes through to the bottom of the anchoring support 2. Then, the locking pin 12 passes through the second through hole 7 of the second piston rod 6 to lock the second piston rod 6 at the bottom of the anchoring support 2. After locking, due to the setting of the fixing plate 8, the distance between the anchoring support 2 and the gantry crane 4 is further reduced, so that the torque of the force exerted by the gantry crane 4 on the connection between the second piston rod 6 and the locking component is reduced. This can effectively improve the bending moment resistance of the second piston rod 6 after it is connected to the locking component, so as to stably anchor the gantry crane 4 and extend the service life of the entire anchoring structure.
