Description

Technical Field

[0001] This utility model relates to the field of monorail crane technology, specifically a heavy-duty lifting beam for monorail cranes. Background Technology

[0002] A monorail system is a system that uses a specially designed I-beam suspended above a tunnel as a track. Various types of suspended vehicles are connected together and pulled along the track by traction equipment. The traction power can be provided by wire ropes, diesel engines, batteries, or pneumatic devices. A monorail is a highly mobile, fast-moving, high-capacity, and safe auxiliary transport device that travels on a suspended monorail system. It is mainly used for installation and retraction in fully mechanized coal mining faces.

[0003] A search revealed a utility model patent in China, CN221821726U, which discloses a lifting beam structure for a monorail crane. The general description includes an I-beam and grooves on both the front and rear sides of the I-beam. When the monorail crane slips, the rollers roll inside the grooves. When a roller contacts a stop block, the stop block acts as a decelerator and buffer. The rollers press against the stop block, causing it to move upwards. At this time, the guide frame extension rod moves upwards, stretching the spring. When the roller has completely passed the stop block, the spring releases its force, causing the stop block to move downwards and return to its original position. This process... The above-mentioned device achieves the purpose of slowing down the rollers, thereby reducing the speed of lifting goods, preventing goods from tipping over and causing damage, and avoiding injury to workers. However, the above-mentioned device still has certain shortcomings. For example, after a period of use, the springs will experience fatigue, loosening, wear, and performance degradation, so they need to be maintained and replaced frequently. When replacing the springs, the connecting strips, guide frames, etc., need to be disassembled, and multiple nuts need to be removed. Disassembly is time-consuming and laborious, and spring replacement is complicated and cumbersome, resulting in long maintenance time and delaying the use of mechanical equipment. Therefore, we propose a heavy-duty lifting beam for monorail cranes. Utility Model Content

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.

[0015] Example Please see Figures 1-4 A heavy-duty lifting beam for a monorail crane includes a lifting beam body 1, and further includes: Mounting plate 2 is detachably connected to the lifting beam body 1. Four support columns 3 are fixedly connected to the mounting plate 2. A lifting plate 4 is slidably connected to the four support columns 3. Two stops 5 are fixedly connected to the lifting plate 4. The stops 5 penetrate the mounting plate 2 and the lifting beam body 1. A fixing plate 6 is fixedly connected to the four support columns 3. The elastic mechanism is mounted on the mounting plate 2, the fixed plate 6, and the lifting plate 4. The elastic mechanism includes a threaded groove, an opening, and two sliding grooves. The threaded groove is located on the mounting plate 2, and the two sliding grooves are located on the lifting plate 4 and the fixed plate 6, respectively. A slider 7 is slidably connected in the sliding groove, and two springs 8 are fixedly connected between the two sliders 7. The opening is located on the mounting plate 2, the fixed plate 6, and the lifting plate 4, and a fixed rod 9 is located in the opening. A threaded block 10 is fixedly connected to the fixed rod 9 and threadedly connected in the threaded groove. The springs 8 are used to apply pressure to the lifting plate 4 and the two stops 5. The sliding grooves and sliders 7 are designed for easy disassembly and replacement, which facilitates the replacement of sliders 7 and springs 8 and improves practicality. A limiting mechanism is provided on the fixed plate 6. The limiting mechanism includes a fixed block 11, which is fixedly connected to the fixed plate 6. Two sliding rods 12 are slidably connected through the fixed block 11. A fixed frame 13 is fixedly connected to the two sliding rods 12. One end of the fixed rod 9 is located inside the fixed frame 13. A second spring 14 is sleeved on the sliding rod 12 to provide elastic force. The fixed frame 13 is used to limit the top end of the fixed rod 9, preventing the fixed rod 9 from rotating and improving stability.

[0016] Multiple mounting screws 15 are fixedly connected to the lifting beam body 1. Multiple mounting holes are opened on the mounting plate 2. The mounting screws 15 are located in the mounting holes. Nuts 16 are threadedly connected to the mounting screws 15 to facilitate the installation and disassembly of the mounting plate 2.

[0017] Two positioning posts 17 are fixedly connected to each of the two sliders 7. The four positioning posts 17 are in pairs. The spring 8 is sleeved on the two positioning posts 17 to stabilize the spring 8 and reduce the probability of the spring 8 being deformed due to frequent compression.

[0018] Pull rings 18 are fixedly connected to the two slide rods 12 to facilitate the movement of the two slide rods 12.

[0019] A pull ring 219 is fixedly connected to the slider 7 to facilitate pulling out the slider 7.

[0020] In summary, the working principle and process of this heavy-duty lifting beam for monorail cranes are as follows: First, the heavy-duty lifting beam is placed at the required location. Then, in the event of slippage, the roller contacts the stop block 5, causing the lifting plate 4 and its slider 7 to rise. The lifting plate 4 slides on the support column 3 and the fixed rod 9, compressing the two springs 8. At this time, the stop block 5 can decelerate the roller. After the roller moves past the stop block 5, the springs 8 rebound and the stop block 5 falls back to its original position. When maintenance requires replacing the springs 8, the pull ring 18 is used to pull the two sliding rods 12 and the fixed frame 13 to move. The spring 14 is compressed, and the fixed frame 13 no longer limits the fixed rod 9. Then, the fixing rod 9 can be rotated. After removing the fixing rod 9 and the threaded block 10, the two pull rings 19 can be used to pull out the two sliders 7 and the two springs 8 for replacement. This device is simple and quick to operate, reduces maintenance time, and improves practicality. The lifting beam body 1 involved in this solution is the authorized technology disclosed in the utility model patent with Chinese Patent Publication (Announcement) No. CN221821726U. Its internal structure and working principle are well known to those skilled in the art and are not the innovation of this patent. The innovation of this patent lies in facilitating the maintenance and replacement of the springs 8. Therefore, this patent will not elaborate on its internal structure and working principle.

[0021] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
