Description

Technical Field

[0001] This utility model relates to the field of crane technology, specifically to an easily detachable and movable container gantry crane. Background Technology

[0002] Gantry cranes are a type of bridge crane, also known as portal cranes. They are mainly used for loading and unloading cargo and bulk materials in outdoor freight yards and material yards. Gantry cranes are characterized by high site utilization, large operating range, wide adaptability, and strong versatility, and are widely used in port freight yards for lifting containers, etc. Their metal structure resembles a portal frame, with two legs installed under the main beam, allowing them to travel directly on ground-level tracks. The main beam may have cantilever beams extending outwards at both ends.

[0003] Existing mobile container gantry cranes are inconvenient to disassemble during actual use, resulting in low disassembly efficiency. Consequently, they are difficult to replace or maintain, leading to low replacement or maintenance efficiency and a lack of practicality. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] See Figure 1-5A detachable and movable container gantry crane includes a main component 1; the main component 1 includes mounting plates 11, with bases 12 fixedly connected to their bottoms, and two mounting plates 11 are symmetrically arranged; a crossbeam 13 is disposed on the two mounting plates 11; a lifting mechanism 14 is disposed on the crossbeam 13; a disassembly assembly 2 is disposed on the mounting plates 11, the disassembly assembly 2 including: a connecting plate 21, with a connecting plate 21 inserted inside each mounting plate 11, and a limit groove formed on the rear surface of each connecting plate 21; a container body 22, with a container body 22 fixedly connected to the rear surface of each mounting plate 11; a threaded rod 24, with a threaded rod 24 inserted into the top of each container body 22, and each threaded rod 24 is rotatably connected to the container body 22; a pressing block 25, with a pressing block 25 threadedly connected to the outer wall of each threaded rod 24, and each pressing block 25 is slidably connected to the container body 22 on the same side; and a limit block. 26, each of the first housings 22 has a slidably connected limit block 26 inside, and each limit block 26 is inserted into the limit groove of the connecting plate 21 on the same side; pull plate 23, each of the limit blocks 26 has a pull plate 23 fixedly connected to its bottom; drive mechanism 27, disposed on the mounting plate 11; the drive mechanism 27 includes: second housing 275, fixedly connected to the top of the two first housings 22, and each threaded rod 24 is inserted into the second housing 275; electric Motor 271 is fixedly connected to the outer wall of housing 275; drive rod 272 is fixedly connected to the output end of motor 271 and rotatably connected to the inner wall of housing 275; bevel gear 273 is symmetrically arranged on the outer wall of drive rod 272; bevel gear 274 is fixedly connected to the top of each threaded rod 24 and meshes with bevel gear 273 on the same side; each pull plate 23 is provided with a guide rail cover 5.

[0029] When ready for use, the operator moves the device to the designated position using the base 12, and then hoists it using the lifting mechanism 14 fixed on the crossbeam 13. After use, when the device needs to be disassembled, the operator drives the two threaded rods 24 to rotate simultaneously using the drive mechanism 27. This causes the two threaded rods 24 to move the two side pressing blocks 25 upwards, releasing the pressure on the same-side limiting block 26. Then, the operator pulls the pull plates 23 on both sides of the housing 22, causing the pull plates 23 to move their top limiting blocks 26 out of the same-side connecting plate 21 and mounting plate 11, releasing the limiting fixation between the mounting plate 11 and the connecting plate 21. Thus, the operator can remove the connecting plate 21, the crossbeam 13, and the device on it. The operation is simple, improving the practicality of the device. The operator turns on the motor 271 on the housing 275, which drives the drive rod 272 to rotate simultaneously. The rotation of the drive rod 272 causes the two bevel gears 273 to drive the two bevel gears 274 to rotate, which in turn drive the two threaded rods 24 to rotate simultaneously. The simple operation improves the convenience of the device. When the pull plate 23 moves, it drives the guide rail cover 5 on it to fold or unfold simultaneously. The guide rail cover 5 can cover the slide groove required for the movement of the pull plate 23 on the housing 22, preventing external dust and other debris from entering the interior of the housing 22 through the slide groove, causing internal blockage and inconvenience for cleaning, thereby improving the stability of the device.

[0030] Example 2

[0031] See Figure 1-5 Based on Embodiment 1, auxiliary functions have been added;

[0032] The mounting plate 11 is provided with an auxiliary component 3, which includes: a mounting block 31, fixedly connected to the top of the housing 275; a motor 32, fixedly connected to the top of the mounting block 31; a threaded rod 33, fixedly connected to the output end of the motor 32; a fixing block 34, threadedly connected to the outer wall of the threaded rod 33 and slidably connected to the inner wall of the mounting block 31; the fixing block 34 is provided with an arc-shaped surface; and each limiting block 26 is provided with a spring 4.

[0033] After installation, the operator turns on motor 2 (32), causing motor 2 (32) to drive threaded rod 2 (33) to rotate simultaneously. Threaded rod 2 (33) then moves fixed block 34 downwards within mounting block 31, thus pressing and fixing it against drive rod 272. This reduces the possibility of shaking during use, which could affect the stability of the pressing block 25 pressing against limit block 26, thereby improving the safety of the device. The contact surface between fixed block 34 and drive rod 272 is provided with an arc shape, which increases the friction between fixed block 34 and drive rod 272, further improving the fixing effect of the device. When pressing block 25 moves upwards and no longer presses against limit block 26, spring 4 automatically pulls limit block 26 back into housing 22, eliminating the need for manual pulling via pull plate 23, thus improving the convenience of the device.
