Description

Technical Field

[0001] This utility model relates to the field of crane technology, specifically to a crane boom mechanism. Background Technology

[0002] A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. It is also known as an overhead crane, gantry crane, or hoist. Currently, the length of the crane's boom mechanism is fixed, making it difficult to adjust and limit the length of the boom mechanism according to usage requirements. This reduces the range of movement of objects lifted by the boom mechanism. Moreover, most existing boom mechanisms are single transmission devices, which reduces the effectiveness of the boom mechanism.

[0003] Chinese patent document CN221093504U discloses a crane boom mechanism, including a crossbeam with a groove. A sliding beam is slidably mounted inside the groove. A first telescopic rod is fixedly mounted on the left side of the sliding beam. The sliding beam is slidably mounted inside the crossbeam, and the first telescopic rod is fixedly mounted on the left side of the sliding beam, which facilitates the fixed and limited movement of the sliding beam. This allows the sliding beam to slide left and right within the groove, thus achieving the effect of extending the crossbeam to the right. At the same time, a second transmission device is fixedly mounted via a second telescopic rod. A limiting block is fixedly mounted on the upper end of the second transmission device and slides inside the limiting groove, which facilitates the left and right movement and limitation of the second transmission device. The first transmission device moves left and right by moving the sliding beam, thereby increasing the range of motion for lifting heavy objects. The hooks can move left and right at the lower ends of both the crossbeam and the sliding beam to lift heavy objects. However, the device increases the weight burden at the connection between the crossbeam and the column due to the cooperation of the crossbeam and the sliding beam, which may lead to breakage. Therefore, we propose a crane boom mechanism. Summary of the Invention

[0014] 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. Example

[0015] Please see Figure 1-6 This utility model provides a technical solution: a crane boom mechanism, including a support column 2, an inclined branch 1 fixedly connected to the front side of the outer surface of the support column 2, a beam arm mechanism 4 fixedly connected to the upper end of the support column 2, a support group 3 jointly provided on the lower rear side of the beam arm mechanism 4 and the lower rear side of the outer surface of the support column 2, a crane 5 provided on the lower side of the middle part of the outer surface of the beam arm mechanism 4, and a crane 6 provided on the lower side of the front front of the support group 3.

[0016] It should be noted that the specific installation method, circuit connection method, and control method of crane 5 and crane 6 in this utility model are all conventional designs and are standard design methods used by designers. The beam arm mechanism 4 is fixedly installed on the upper end of the support column 2 and is further supported on the front side of the support column 2 by the inclined branch 1. Goods are lifted by crane 5 and crane 6.

[0017] The beam arm mechanism 4 includes a column 41. Rotating seats 42 are fixedly connected to both the upper and lower sides of the outer surface of the column 41. A driving component 44 is fixedly connected to the rear of the outer surface of the upper rotating seat 42. A support block 47 is fixedly connected to the middle of the outer surface of the column 41. A rotating groove 45 is opened on the front side of the middle of the upper end of the support block 47. The inner cavity of the rotating groove 45 and the inner cavity of the two rotating seats 42 are jointly provided with the beam arm assembly 46. The output end of the driving component 44 is meshed with the upper rear part of the beam arm assembly 46 through a chain. An installation groove 43 is opened on the rear side of the lower end of the support block 47. The lower end of the column 41 is fixedly connected to the upper end of the support column 2.

[0018] First, it needs to be explained that the drive motor and the small gear plate are composed of a beam arm mechanism 4, which is fixedly installed on the support column 2 via the column 41. When the drive motor is started, the small gear plate drives the beam arm assembly 46 to rotate in the inner cavity of the two rotating seats 42 and the inner cavity of the rotating groove 45 via the chain. This allows the beam arm assembly 46 to rotate within a certain range, and the goods are lifted by the crane 5 and the crane 6. Ultimately, this increases the range of goods that the device can lift and improves the flexibility of the device. Furthermore, by adding a support block 47 with a rotating groove 45, the beam arm assembly 46 is more stable during rotation, preventing the connection between the beam arm assembly 46 and the rotating seat 42 from breaking due to excessive weight, thus increasing the safety of the device.

[0019] The beam arm assembly 46 includes a pivot 461, with a large gear 462 fixedly connected to its upper end. A crossbeam slide rail 463 is fixedly connected to the lower front end of the pivot 461. A motor 464 is fixedly connected to the upper rear end of the crossbeam slide rail 463. An inclined beam 469 is fixedly connected to the upper front end of the pivot 461. A housing 465 is fixedly connected to the lower end of the inclined beam 469 and the upper end of the crossbeam slide rail 463. A threaded rod 466 is rotatably connected to the middle of the inner cavity of the housing 465. The rear end of the threaded rod 466 passes through the inner cavity of the housing 465 and is fixedly connected to the output end of the motor 464. The bottom of the inner cavity of the housing 465... Several rollers 467 are provided on both sides of the wall. The outer surfaces of the rollers 467 and the outer surfaces of the threaded rods 466 are provided with an inner beam slide rail 468. The outer surface of the inner beam slide rail 468 is slidably connected to the inner cavity of the outer shell 465. The upper and lower sides of the outer surface of the rotating shaft 461 are rotatably connected to the inner cavities of the two rotating seats 42 respectively. The middle part of the outer surface of the rotating shaft 461 is rotatably connected to the inner cavity of the rotating groove 45. The large gear plate 462 is meshed with the output end of the drive component 44 through a chain. The lower side of the outer surface of the crossbeam slide rail 463 is slidably connected to the crane 5. The lower side of the outer surface of the inner beam slide rail 468 is slidably connected to the crane 6.

[0020] In detail, it should be noted that the specific installation method, circuit connection method, and control method of the motor 464 in this utility model are all conventional designs, which are standard design methods used by designers. When the drive motor in the drive component 44 drives the small gear plate and chain to rotate, it will drive the large gear plate 462 to rotate. The rotation of the large gear plate 462 drives the rotating shaft 461 to rotate between the inner cavities of the two rotating seats 42 and the inner cavity of the rotating groove 45. When it rotates to a suitable angle, the crane 5 is started to slide on the crossbeam slide rail 463. The crane 5 lifts the goods. When the crane 5 slides on the crossbeam slide rail 463 for a certain length... When the load cannot be lifted, start motor 464 to rotate threaded rod 466 inside the outer shell 465. The rotation of threaded rod 466 causes inner beam slide rail 468 to move outward to a suitable distance on the outer surface of roller 467 and inside the outer shell 465. Then start crane 6 to slide on the lower side of the outer surface of inner beam slide rail 468. Lift the load using crane 6, further increasing the lifting range. In addition, the addition of roller 467 reduces the friction between inner beam slide rail 468 and the inner shell 465, reducing resistance during movement and thus improving movement efficiency and extending equipment life.
