Description

Technical Field

[0001] This utility model belongs to the field of crane technology, and in particular relates to a stable and reliable electric hoist gantry crane. Background Technology

[0002] Electric hoist gantry cranes are lifting equipment commonly used for heavy object handling. They combine the structural features of electric hoists and gantry cranes, offering high work efficiency and operational safety. They are widely used in ports, factories, warehouses, and workshops for hoisting, handling, and lifting heavy objects.

[0003] Existing electric hoist gantry cranes rely on the electric hoist to drive and rewind the traction steel rope to lift heavy objects. They also work with electric slide rails to move heavy objects to different positions. However, due to the influence of load inertia and wind force during lifting and transportation, the traction steel rope is prone to swinging, which reduces the stability of the entire lifting and transportation process. In severe cases, the goods may fall off the hook, posing a safety hazard.

[0004] To address these issues, we provide a stable and reliable electric hoist gantry crane. Utility Model Content

[0005] The purpose of this utility model is to provide a stable and reliable electric hoist gantry crane. By combining the anti-sway support component and the guide component, the problem of poor stability during lifting and transport in the prior art of gantry cranes is solved.

[0026] Please see Figures 1-5 This utility model is a stable and reliable electric hoist gantry crane, including a base 1, a truss 2 on the top of the base 1, and an electric hoist body 3 at the bottom of the truss 2. The electric hoist body 3 is a lifting device widely used in industry, construction and warehousing, used to lift and move heavy objects. It is driven by an electric motor and has high working efficiency and convenience. It is often used in conjunction with cranes and suspension rails, etc. It is a mature existing technology and will not be described in detail here. The bottom of the electric hoist body 3 is provided with a hook 4; the bottom of the electric hoist body 3 is provided with a support anti-sway component, which includes a horizontal plate 5 at the bottom of the electric hoist body 3, a connecting frame 6 fixedly connected to the bottom of the horizontal plate 5, and a support roller 7 fixedly connected to one side of the connecting frame 6; the top of the horizontal plate 5 is provided with a guide component, which includes a guide rod 8 fixedly connected to the top of the horizontal plate 5 and a limiting plate 9 fixedly connected to the top of the guide rod 8. Example

[0027] Please see Figures 1-5Based on Embodiment 1, the anti-sway support assembly also includes a connecting belt 10 fixedly connected to one side of the hook 4. The end of the connecting belt 10 away from the hook 4 is fixedly connected to the connecting frame 6. The connecting belt 10 is in contact with the surface of the support roller 7 and is supported by the support roller 7 to make it taut. A baffle 11 is fixedly connected to the bottom of the connecting frame 6. The hook 4 is in contact with the baffle 11. A first electric drive seat 12 is provided inside the base 1. A support column 13 is fixedly connected to the top of the first electric drive seat 12. A second electric drive seat 14 is provided inside the truss 2. A movable frame 15 is fixedly connected to the bottom of the second electric drive seat 14. The first electric drive seat 12 and the second electric drive seat 14 are the core parts for realizing the sliding rail to move forward and backward, up and down or in other directions. It uses an electric motor and transmission mechanism to move objects along a slide rail, which is a mature existing technology and will not be described in detail here. The first electric drive seat 12 is in contact with the base 1 and the second electric drive seat 14 is in contact with the truss 2. The first electric drive seat 12 and the base 1 cooperate to realize hoisting in the front and back direction, and the second electric drive seat 14 and the truss 2 cooperate to realize hoisting in the left and right direction. The top of the support column 13 is fixedly connected to the truss 2, the bottom of the movable frame 15 is fixedly connected to the electric hoist body 3, the top of the guide rod 8 extends to the top of the movable frame 15, the surface of the electric hoist body 3 is wound with a traction steel rope 16, the bottom end of the traction steel rope 16 is fixedly connected to the horizontal plate 5, a horizontal bar is fixedly connected to one side inside the truss 2, a sliding sleeve is fitted on the surface of the horizontal bar, the bottom of the sliding sleeve is fixedly connected to the second electric drive seat 14, and the sliding sleeve can move along the horizontal bar surface. A mounting plate is fixedly connected to one side of the base 1, and a mounting hole is opened on the top of the mounting plate.

[0028] The working principle of this utility model is as follows: When the electric hoist body 3 operates, it winds up the traction steel rope 16, lifting the hook 4 and the load to the required height. During this process, the guide rod 8 moves upward along the movable frame 15, limiting the swing of the traction steel rope 16 and ensuring the verticality and stability of the lifting. The support roller 7 provides support to the connecting belt 10, keeping it taut at all times and limiting the left and right swing of the hook 4. The hook 4 is located between two baffles 11, which prevent the hook 4 from swinging back and forth, ensuring stability during the lifting process.

[0029] The first electric drive unit 12 drives the support column 13 and the truss 2 to move back and forth as a whole, realizing the forward and backward lifting of heavy objects. The second electric drive unit 14 drives the electric hoist body 3 to move along the horizontal bar through the movable frame 15, realizing the left and right lifting of heavy objects. The sliding of the sleeve on the horizontal bar further enhances the stability of the movement. The crane is fixed in the working position by the mounting plate and mounting holes to ensure the stability of the equipment during operation. Through the above design and working mechanism, this electric hoist gantry crane achieves high stability and reliability during lifting and transportation, effectively solving the problems of poor stability and safety caused by the swaying of traditional cranes.
