Description

Technical Field

[0001] This utility model relates to the field of crane hook technology, and more specifically to a crane hook anti-detachment locking structure. Background Technology

[0002] Traditional crane hook anti-derailment locking structures mostly employ a fixed design. Once this structure is damaged, it often requires complete replacement, increasing maintenance and replacement costs and potentially leading to prolonged equipment downtime and reduced work efficiency. Furthermore, fixed structures place high demands on structural stability and reliability during hoisting; even minor loosening or deformation can pose safety hazards, limiting its flexibility in complex working conditions. Therefore, this design may face both economic and practical challenges in long-term use. Utility Model Content

[0003] The purpose of this utility model is to provide a crane hook anti-detachment locking structure in order to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A crane hook anti-derailment locking structure includes two triangular pieces, a hook, a hook seat, a reinforcing connector, a sleeve, and a threaded cap. Two triangular pieces are provided, spaced apart by the sleeve to form a space for installing the hook seat. The two triangular pieces pass through the sleeve via the reinforcing connector, enhancing the overall structural stability of the hook. The reinforcing connector has external threads at both ends, secured by the threaded cap. The hook seat has protrusions at both ends, each with external threads, secured by threaded caps. A rod is mounted at the top of the hook, passing through the hook seat and secured by a threaded cap. All components are secured by threaded caps, simplifying installation and maintenance, reducing operational complexity, and the structural design is adaptable to high-load applications.

[0006] The hook has a double-hook structure. The double-hook design can better distribute the load, improve the stability of the lifting process, reduce swaying and tilting, and avoid excessive stress on a single point.

[0007] The hook in this invention adopts a highly efficient assembly structure design, and the cost of the components used is generally low. The hook is easy to assemble and can be quickly installed and disassembled, improving work efficiency. It is especially suitable for occasions where hook replacement is required frequently.

[0008] A preferred technical solution involves using three connectors, positioned at the three corners of the triangular piece. These three connectors distribute stress more evenly, preventing localized stress concentration and extending the structure's service life. They also enhance the structure's load-bearing capacity, enabling it to withstand greater loads. The connector materials must possess high strength and durability, such as high-strength steel or aluminum alloy.

[0009] A preferred technical solution: A gasket is provided on the inside of the threaded cap. The gasket can absorb and reduce vibration, reduce noise caused by vibration, and improve user comfort. The gasket can increase friction, prevent the threaded cap from loosening due to vibration or load changes, and improve the reliability of the connection.

[0010] A preferred technical solution: The hook seat is equipped with a limiting part, which can effectively prevent the hook from accidentally disengaging during use, thus improving safety. The hook seat and limiting part are preferably made of high-strength steel.

[0011] A preferred technical solution: Several screws are also provided on the side end of the threaded cap that mates with the protrusion. The number and distribution of the screws need to be designed reasonably according to the specific application requirements to ensure connection strength and stability.

[0012] A preferred technical solution: The threaded cap installed on the side of the protrusion is the first threaded cap, and the washer provided on its inner side is the first washer. The first washer and the triangular piece have through holes through which the screw passes. Similarly, the triangular piece has other through holes for the reinforcing connector to pass through.

[0013] A preferred technical solution: The opening is provided with an internal thread.

[0014] A preferred technical solution: A threaded cap is provided at the end of the screw.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model enhances the overall structural stability of the hook by strengthening the design of the connecting parts and sleeve, which can effectively distribute the force during the hoisting process and reduce the risk of deformation or damage.

[0017] 2. The components of this utility model, such as the triangular plates, sleeves, and reinforcing connectors, adopt a modular design, which facilitates disassembly and replacement, reducing maintenance costs and time. The space between the triangular plates, formed by the sleeves, creates a space for installing the hook seat, making the installation and adjustment of the hook seat more flexible and adaptable to different working conditions.

[0018] 3. The protrusions and threaded locking design at both ends of the hook seat in this utility model, combined with the rod locking method at the top of the hook, can effectively prevent the hook from accidentally coming off during the hoisting process, thus improving safety.

[0019] 4. The reinforced connectors and threaded locking mechanism in this invention improve the overall strength and durability of the structure, enabling it to withstand larger loads and frequent use. The threaded connections between components facilitate disassembly, inspection, and replacement of damaged parts, eliminating the need for complete replacement and reducing operating costs.
