Description

Technical Field

[0001] The utility model relates to the technical field of port machinery and equipment, and specifically designs a protective device for an anchoring component of a gantry crane device. Background Art

[0002] Portal cranes are gantry cranes. They operate along coastal crane tracks, with one side facing land and the other facing the sea. They are used for lifting and loading and unloading operations between storage yards and ships.

[0003] In strong winds, gantry cranes need to be anchored to the ground or foundation to ensure stability under wind pressure and prevent dangerous situations such as vibration, tipping, or slipping. Traditional anchoring components include embedded fixings with hinged connectors. Some anchoring components protrude from the ground and lack protection, easily obstructing traffic and providing no protection. Some, while protected, are neither dustproof nor waterproof. Harsh port environments allow dust and rainwater to enter protective devices, causing accumulation of water and mud, making them difficult to clean. This can cause severe rusting of anchoring components, preventing the pins at the hinges from moving flexibly, affecting the lifespan of the anchoring components and the safety of the equipment. This is especially true in winter when ice forms and the equipment becomes unusable. Summary of the Invention

[0004] The utility model provides a protective device for a door crane anchoring assembly, which can achieve the purpose of sealing the ground anchoring assembly without affecting traffic, being waterproof and rust-proof, and being easy to use.

[0005] The utility model provides a protective device for a door machine anchoring assembly, comprising a pit, an anchoring assembly being arranged in the pit, and a sealing base being arranged on the pit; the sealing base comprises a base plate, an air avoidance is arranged in the middle of the base plate, and the air avoidance area corresponds to the anchoring assembly; a sealing groove is arranged on a circumference of the base plate, and a sealing strip is arranged in the sealing groove; the sealing cover plate comprises a sealing top plate, an inserting plate is arranged below the sealing top plate, and the position of the inserting plate corresponds to the position of the sealing groove; the outside of the sealing top plate corresponds to the ground, and a handle is arranged on the outside of the sealing top plate.

[0006] Furthermore, the handle is a concave structure provided on the sealed top plate, and a handle is provided on the top surface of the concave structure.

[0007] Furthermore, the sealing strips are arranged on both sides of the inner wall of the sealing groove, and the outer side surface of the inserting plate corresponds to the sealing strips.

[0008] Furthermore, the sealing strip is arranged at the bottom of the sealing groove, and the end surface of the inserting plate corresponds to the sealing strip.

[0009] Furthermore, reinforcing ribs are provided below the sealing top plate.

[0010] Furthermore, a vertical plate is provided on the circumference of the base plate, and a sealing strip is provided on the outer side of the vertical plate; and an inserting plate is provided below the sealing top plate to correspond to the sealing strip.

[0011] Furthermore, the sealing strip is arranged on the base plate outside the vertical plate, and the end surface of the inserting plate corresponds to the sealing strip.

[0012] This utility model provides a protective device for the anchor assembly of a gantry crane with excellent sealing and waterproofing, preventing dust and rainwater from entering the protective device, which could lead to accumulation of water and mud and make cleaning difficult. It also protects the anchor assembly and reduces rust, extending its lifespan and ensuring equipment safety. It also functions normally during winter freezing periods. The sealed top plate features a recessed handle for easy removal without protruding from the ground, thus avoiding obstruction. This device has positive implications for the windproof anchoring of gantry cranes at ports and terminals. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] Example 1

[0023] A gantry crane anchor assembly protection device is arranged on the outer side of the crane track at a position corresponding to the gantry crane bracket, and generally two are symmetrically arranged; it includes a pit 1, an anchor assembly 2 is arranged in the pit, a sealing base 13 is arranged on the pit, and the pit and the surrounding area of ​​the sealing base are sealed with concrete; in this embodiment, a rectangular steel plate is used to make a base plate 3, and a gap 4 is set in the middle of the base plate by laser cutting, and the gap area is used to expose the anchor assembly; two circles of steel plates of equal height are welded around the remaining annular base plate to form a sealing groove 5.

[0024] A sealing strip 6 is provided in the sealing groove; here, the sealing strip can be provided only on both sides of the inner wall of the sealing groove, so that the outer side surfaces of the plugboard correspond to the sealing strip, thereby achieving a sealing effect; the sealing strip can also be provided at the bottom of the sealing groove, in which case the end surface of the plugboard corresponds to the sealing strip, thereby achieving a sealing effect. Of course, when using this sealing method, it is necessary to pay attention to cleaning impurities on the sealing strip before inserting the plugboard 7; of course, sealing strips can also be provided on both sides and the bottom of the inner wall of the sealing groove, which has a better sealing effect.

[0025] The sealing cover plate 8 includes a sealing top plate 9, and an insert plate 7 is arranged on the bottom surface of the sealing top plate. The position and height of the insert plate correspond to the position and depth of the sealing groove, respectively, so as to achieve a better sealing effect. After the sealing cover plate is installed on the sealing base, the outer surface of the sealing top plate corresponds to the ground, so as to achieve the purpose of not obstructing traffic.

[0026] To facilitate disassembly, a handle 10 is provided on the outside of the sealed top plate. To prevent the handle from protruding from the outside of the sealed top plate, a recessed structure is provided on the sealed top plate. The recessed structure can be stamped or laser-cut into a circular hole in the top surface of the sealed top plate, where a semicircular shell 11 is welded. A handle 12 is welded to the edge of the recessed structure. Two handles should be provided symmetrically to facilitate balance during lifting.
