Description

Technical Field

[0001] This utility model belongs to the technical field of crane lifting equipment, and in particular, a single-hook gantry crane beam. Background Technology

[0002] In steelmaking, some sections sometimes require the movement of containers with double lifting lugs, depending on the production process. However, a single crane often only has one hook and cannot handle containers with double lifting lugs. Therefore, it is necessary to call in another crane to assist in the work. Since the two cranes need to work in close proximity simultaneously, collisions sometimes occur, affecting production safety, disrupting normal operations, and increasing production costs. Furthermore, when two cranes are in operation, the work being done by the other crane cannot continue, significantly reducing production efficiency and causing inconvenience to production. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a single-hook gantry crane beam.

[0004] The technical solution of this utility model: A single-hook gantry crane beam is disclosed, which can be detachably connected to the hook of a crane. The beam includes a crane connector, a crossbeam, a fixing component, and a hook connector. The crossbeam is arranged horizontally, and the crane connector is arranged vertically. The crane connector is coaxially fixed at the geometric center of the upper surface of the crossbeam, and the top of the crane connector engages with the hook of the crane. The crane connector can be detachably connected to the hook of the crane, allowing the crane to move the crossbeam and maintain balance via the crane connector. The fixing component is arranged vertically and symmetrically installed on both sides of the crossbeam. The upper surface of the fixing component is tightly fixed to the lower surface of the crossbeam. The hook connector is arranged vertically, and its upper part is connected to the lower part of the fixing component. A hook can be installed on the lower part of the hook connector, and the hook can lift the container to be lifted. The hook connectors and hooks on both sides are symmetrically arranged vertically.

[0005] Furthermore, the lifting beam also includes a crane connecting shaft, a fixing member connecting shaft, and a hook connecting shaft. The upper part of the crane connecting member is open, and the crane connecting shaft is arranged horizontally and located within the upper opening of the crane connecting member. The crane can be connected to the crane connecting member through the crane connecting shaft. The lower part of the fixing member is open, and the fixing member connecting shaft is arranged longitudinally and installed within the lower opening of the fixing member. The upper part of the hook connecting member has a through hole arranged longitudinally, and the hook connecting member is connected to the fixing member through the fixing member connecting shaft and the through hole. The lower part of the hook connecting member is open, and the hook connecting shaft is installed horizontally and located within the lower opening of the hook connecting member. The hook is connected to the hook connecting member through the hook connecting shaft. Simultaneously, due to the bridging of the hook connecting member, the hook can also swing horizontally through the fixing member connecting shaft and the hook connecting member.

[0006] Furthermore, the lifting beam also includes an insulation partition, which is installed on the lower surface of the beam and on the side of the two fixing members near the crane connector.

[0007] The advantages and effects achieved by this utility model are: 1. This utility model enables a single crane to safely lift containers with double lifting lugs, completely avoiding the interference and collision hazards in multi-machine collaboration and significantly improving on-site operational safety. Only one crane is needed to complete the task that originally required two cranes, freeing up the operating capacity of the other crane, avoiding production interruptions, and significantly improving overall lifting efficiency. It is especially suitable for continuous production environments such as steelmaking.

[0008] 2. In this utility model, the lifting beam adopts a bridging structure of crossbeam, fixing component, and hook connector, which enhances the overall rigidity and load-bearing stability. Through the cooperation of the crane connecting shaft, the fixing component connecting shaft, and the hook connecting shaft, the hook can swing flexibly in the longitudinal and horizontal directions, facilitating quick docking with the container lifting lug and improving the convenience and accuracy of lifting operations.

[0009] 3. This utility model allows for the replacement of lifting hooks according to the type of lifting lugs for different containers, possessing excellent versatility and adaptability. It eliminates the need for customized lifting tools for different containers, reducing equipment investment and maintenance costs. By installing thermal insulation baffles on the lower surface of the crossbeam and the sides of the fixing components, high temperatures are effectively isolated, preventing structural damage or connection failure caused by thermal expansion of the lifting beam, thus extending the equipment's service life. It is particularly suitable for lifting high-temperature liquid containers. Attached Figure Description

Detailed Implementation

[0011] The present invention will be further described below with reference to the embodiments. The following embodiments are descriptive and not limiting, and should not be used to limit the protection scope of the present invention.

[0012] The various experimental operations involved in the specific embodiments are all conventional techniques in the field. For parts not specifically annotated in this document, those skilled in the art can refer to various commonly used reference books, scientific and technological documents or related instructions and manuals prior to the application date of this utility model to carry out the operations.

[0013] A single-hook gantry crane beam, such as Figures 1 to 4 As shown, the lifting beam can be detachably connected to the crane hook (not shown in the figure). The lifting beam includes a crane connector 1, a crossbeam 2, a fixing member 3, and a hook connector 4. The crossbeam is arranged horizontally, and the crane connector is arranged vertically. The crane connector is coaxially fixedly installed at the geometric center of the upper surface of the crossbeam. The top of the crane connector is matched with the crane hook. The crane connector can be detachably connected to the crane hook. The crane can move the crossbeam through the crane connector and maintain balance to ensure safety. The fixing member is arranged vertically and symmetrically installed on both sides of the crossbeam. The upper surface of the fixing member is tightly fixed to the lower surface of the crossbeam. The hook connector is arranged vertically, and the upper part of the hook connector is connected to the lower part of the fixing member. The lower part of the hook connector can be equipped with a hook (not shown in the figure). The hook can lift the container to be lifted. The hook connectors and hooks on both sides are symmetrically arranged vertically. The bridging of the hook connectors enhances the overall structural strength and stability of the lifting beam. The hooks on both sides enable the lifting beam to lift containers with double lifting lugs, expanding the crane's application range.

[0014] In use, this invention connects the crane to the crane connector, then moves the crane above the container to be lifted. The hooks are installed on the hook connectors on both sides of the crossbeam, and then the hooks on both sides are connected to the lifting lugs on the container. The crane is then moved again, allowing it to lift the container with two lifting lugs using only one hook, eliminating the need for other cranes. For containers with different lifting lugs, only the hook needs to be replaced, thus expanding the device's application range and ensuring normal operation. This not only improves work efficiency and reduces labor intensity but also lowers production costs, bringing convenience to production.

[0015] This invention enables a single crane to safely lift containers with double lifting lugs, completely avoiding the interference and collision hazards associated with multi-crane collaboration and significantly improving on-site operational safety. Only one crane is needed to complete the task that previously required two cranes, freeing up the capacity of the other crane, preventing production interruptions, and significantly improving overall lifting efficiency. It is particularly suitable for continuous production environments such as steelmaking. The lifting beam adopts a bridging structure of crossbeams, fixing components, and hook connectors, enhancing overall rigidity and load-bearing stability.

[0016] In this embodiment, as Figure 2 and Figure 3 As shown, the lifting beam also includes a crane connecting shaft 5, a fixing connecting shaft 6, and a hook connecting shaft 7. The upper part of the crane connecting shaft is open (not labeled in the figure), and the crane connecting shaft is arranged horizontally and located within the upper opening of the crane connecting shaft. The crane can be connected to the crane connecting shaft via the crane connecting shaft, which facilitates the connection operation between the crane and the crane connecting shaft and improves work efficiency. The lower part of the fixing shaft is open (not labeled in the figure), and the fixing connecting shaft is arranged longitudinally and installed within the lower opening of the fixing shaft (not labeled in the figure). The upper part of the hook connecting shaft is arranged longitudinally... A through hole (not labeled in the figure) is provided. The hook connector and the fixing part are connected through the fixing part connecting shaft and the through hole, allowing the hook connector to swing horizontally. The lower part of the hook connector is open (not labeled in the figure). The hook connecting shaft is installed horizontally and is located in the lower opening of the hook connector. The hook is connected to the hook connector through the hook connecting shaft, allowing the hook to swing vertically. At the same time, due to the bridging of the hook connector, the hook can also swing horizontally through the fixing part connecting shaft and the hook connector, which makes it easier to install the hook and the container and improves work efficiency.

[0017] By coordinating the crane connecting shaft, the fixing component connecting shaft, and the hook connecting shaft, the hook can swing flexibly in both the longitudinal and horizontal directions, facilitating quick docking with the container lifting lugs and improving the convenience and accuracy of lifting operations. The hook can be replaced according to the type of lifting lugs on different containers, exhibiting good versatility and adaptability. This eliminates the need for custom-made lifting tools for different containers, reducing equipment investment and maintenance costs.

[0018] In this embodiment, as Figure 2 As shown, the lifting beam also includes a thermal insulation partition 8. The thermal insulation partition is installed on the lower surface of the beam and on the side of the two fixing parts near the crane connector. The thermal insulation partition protects the beam when transporting high-temperature liquids, preventing damage to the beam due to defects such as breakage of the connection with the fixing parts after thermal expansion.

[0019] Although embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations, and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments.
