[0002] Gantry cranes are lifting equipment widely used in various industrial fields. They are characterized by an operating platform at the entrance, which can perform a series of operations such as hoisting, handling, and stacking. They are usually composed of a main beam, legs, operating platform, hook, wire rope, etc. Gantry cranes have various structural forms, with single main beam and double main beam being the most common.

[0003] Existing gantry cranes have a constant height during use, which cannot adapt to lifting goods of different heights. They also have poor fixing effect during lifting. Furthermore, their width makes them unable to enter warehouses for storage. Therefore, there is an urgent need for a more versatile gantry crane to overcome these shortcomings. Utility Model Content

[0021] More specifically, the suspended items are fixed by setting the adjustable hanging assembly 4, and the height of the overall device is adjusted by setting the movable lifting assembly 5. When adjusting the overall height, the second motor 592 is turned on, which drives the second threaded rod 591 to rotate, causing the movable rod 51 to move the main track beam 1 upward, thereby adjusting the height of the overall device. When hoisting items, the first motor 41 is turned on according to the width of the items, which drives the first threaded rod 45 to rotate, causing the first slider 44 to move the hook body 46 to the designated position and fix it under the action of the hook body 46. Then, it is lifted by the electric hoist 3, and finally transferred to the designated position by the transfer mechanism 2. When moving the overall device, the threaded frame 57 is rotated, the threaded frame 57 disengages from the inner cavity of the slot 58, releases the limit on the main track beam 1, and the receiving seat 52 is rotated, so that it is in a straight line, which is convenient for passing through narrow gates and has the advantage of convenient adjustment and hoisting.

The second slide grooves 59 are all opened on both sides of the inner cavity of the receiving seat 52. A second slider 593 is slidably connected inside the second slide groove 59. The side of the second slider 593 that is relatively close to the other side is fixedly connected to both sides of the moving rod 51. More specifically, the second slide groove 59 is used to limit the second slider 593 to prevent the second slider 593 from shaking during movement. The second slider 593 is used to limit the moving rod 51 to prevent the moving rod 51 from shaking during movement.

[0024] In some embodiments, the second threaded rod 591 is rotated inside the moving rod 51 by a thread, the output shaft of the second motor 592 is fixedly connected to the bottom of the second threaded rod 591, the top of the moving rod 51 is rotatably connected to the bottom of the main track beam 1 by a bearing, and the fixing block 56 is fixedly installed on the inner side of the moving rod 51. More specifically, the second threaded rod 591 is driven by the second motor 592, thereby indirectly moving the position of the moving rod 51.

[0025] In some embodiments, the threaded bracket 57 is rotated inside the fixing block 56 by a thread, and slots 58 are provided on both sides of the bottom of the main track beam 1. The top of the threaded bracket 57 passes through the slots 58 into the interior of the main track beam 1. The mounting rod 42 is fixedly installed at the bottom of the electric hoist 3. More specifically, the threaded bracket 57 is limited by setting the fixing block 56, and the threaded bracket 57 passes through the slots 58 into the interior of the main track beam 1, thereby indirectly fixing the main track beam 1 and the moving rod 51.

[0026] In some embodiments, a first motor 41 is fixedly installed on the right side of the mounting rod 42, the first slide groove 43 is formed at the bottom of the mounting rod 42, the first sliders 44 slide on both sides of the inner cavity of the first slide groove 43, and the first threaded rod 45 rotates inside the first slider 44 by thread. More specifically, the first slide groove 43 is used to limit the first slider 44 to prevent the first slider 44 from shaking during movement, and the first slider 44 is used to limit the hook body 46 to prevent the hook body 46 from shaking during movement.

[0027] In some embodiments, the output shaft of the first motor 41 passes through the inner cavity of the first slide groove 43 and is fixedly connected to the right side of the first threaded rod 45. The bottom of the first slider 44 is fixedly mounted with a hook body 46. More specifically, the first motor 41 is set to drive the first threaded rod 45 and adjust the position of the first slider 44 and the hook body 46.

[0028] Working principle:

[0029] Step 1: When adjusting the overall height, turn on the second motor 592. The second motor 592 drives the second threaded rod 591 to rotate, which causes the moving rod 51 to move the main track beam 1 upward, thereby adjusting the height of the overall device.

[0030] Step 2: When hoisting items, firstly, according to the width of the item, turn on the first motor 41. The first motor 41 drives the first threaded rod 45 to rotate, causing the first slider 44 to move the hook body 46 to the designated position and fix it under the action of the hook body 46. Then, under the action of the electric hoist 3, it is lifted up. Finally, it is transferred to the designated position by the transfer mechanism 2. When moving the whole device, rotate the threaded frame 57. The threaded frame 57 disengages from the inner cavity of the slot 58, releasing the limit on the main beam 1 of the track. Rotate the receiving seat 52 to make it into a straight line, which is convenient for passing through narrow gates and has the advantage of convenient adjustment and hoisting.
