Description

Technical Field

[0001] This utility model belongs to the technical field of hoisting auxiliary devices, specifically a hoisting auxiliary device for construction materials. Background Technology

[0002] Construction material handling auxiliary devices are tools specifically designed to improve the efficiency and safety of material handling. These devices encompass various types, including hanging platforms, buckets, electric rotary jib cranes, mobile folding gantry cranes, and column-mounted jib cranes. Hanging platforms and buckets use protective netting or baffles to secure loose parts and prevent them from falling off. Electric rotary jib cranes are driven by motors, enabling flexible horizontal and vertical movement, suitable for material handling in workshops. Mobile folding gantry cranes use foldable beams and extendable legs to save space and facilitate relocation in warehouses, construction sites, and other similar environments. Column-mounted jib cranes combine a 360-degree rotating cantilever with an electric chain hoist to achieve short-distance, high-density lifting, commonly used in production workshops and logistics warehouses. Through structural optimization and functional innovation, these devices significantly reduce manual labor intensity and improve construction efficiency and safety.

[0003] An existing patent (publication number: CN216038174U) discloses an auxiliary hoisting device for port construction. This hoist is equipped with a fixing module. When the object to be hoisted moves upward through the internal transmission mechanism and contacts the lower surface of the fixing module, the upper surface of the object is fixed, preventing the object from accidentally slipping, which is safer and more efficient. However, the hoist has poor support capacity and the load-bearing capacity of the screw alone is limited, which can easily cause the screw to bend, thus preventing the internal transmission mechanism from moving normally, resulting in poor performance. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides an auxiliary device for hoisting materials in construction, which effectively solves the problems of poor support capacity of existing hoisting tools, limited load-bearing capacity relying solely on the screw, easy bending of the screw, and inability to make the internal transmission mechanism move normally.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for hoisting construction materials, comprising a hoisting body, a hoisting ring fixedly installed at the top of the hoisting body, a support frame fixedly installed at the bottom of the hoisting body, a handwheel located below the support frame, hanging rings at both ends of the hoisting body, two card seats fixedly installed at the lower parts of both ends of the hoisting body, a transmission component located above the handwheel, booms located on both sides inside the hoisting body, with the ends of the booms that are far apart from each other fixedly connected to the two hanging rings respectively, support rods rotatably installed on both sides of the lower part of the two booms, and the transmission component being connected to the two booms in a transmission connection. When the handwheel rotates, power is output to the two booms through the transmission component, causing the two booms to move backward and extend, while simultaneously causing the four support rods to pop out for support.

[0006] Preferably, the transmission assembly includes a rotating shaft fixedly installed on the top of the handwheel. The surface of the rotating shaft is rotatably installed between the support frame and the bottom of the lifting device body through a bushing. The top end of the rotating shaft extends into the interior of the lifting device body and is fixedly installed with a driving bevel gear. A driven bevel gear is meshed with one side of the surface of the driving bevel gear.

[0007] Preferably, a shaft is fixedly installed in the middle of the driven bevel gear, and threaded rods are fixedly installed at both ends of the shaft. Fixed seats are rotatably installed at both ends of the two threaded rods through shaft seats, and the bottom of the two fixed seats is fixedly connected to the inner bottom of the lifting device body. Threaded sleeves are threadedly connected to the surfaces of the two threaded rods, and sliders are fixedly installed at the bottom of the two threaded sleeves. Slide grooves are opened on both sides of the inner bottom of the lifting device body, and the two sliders are slidably installed inside the two slide grooves.

[0008] Preferably, a transmission rod is rotatably mounted on the upper side of each of the four support rods, mounting slots are provided on both sides of the two booms, a sliding sleeve is rotatably mounted on the top of each of the four transmission rods, the four sliding sleeves are installed inside the four mounting slots, and a sliding rod is inserted into the interior of each of the four sliding sleeves. The four sliding rods are fixedly installed inside the four mounting slots, and a spring is sleeved on the surface of each of the four sliding rods. The two ends of each spring are fixedly connected to the sliding sleeve and the interior of the mounting slot, respectively. Limiting blocks are fixedly mounted on both sides of the two booms, and limiting slots are provided on both sides of the inner wall of the lifting device body. The four limiting blocks are respectively opened inside the corresponding limiting slots.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When hoisting long items, the operator rotates the shaft inside the bushing by rotating the handwheel. When the shaft rotates, the driven bevel gear is driven to rotate through the active bevel gear. When the driven bevel gear rotates, the two threaded rods are driven to rotate along the two shaft seats through the shaft rod. When the two threaded rods rotate, they drive the two threaded sleeves on their surfaces to move in opposite directions. When the two threaded sleeves move, they drive the slider to slide inside the slide groove, which increases the stability of the two threaded sleeves when they move. When the two threaded sleeves move, they drive the two booms to move in opposite directions. When the booms move, they drive the limit blocks to slide inside the limit groove, which increases the stability of the two booms when they move. When the two booms move in opposite directions, they drive the two hanging rings to move in opposite directions and extend, thereby increasing the hoisting length.

[0010] As the two booms move in opposite directions, they drive the four support rods to move as well. When the lower ends of the four support rods move to the positions of the four mounting brackets, the springs push the four sliding sleeves to slide along the surfaces of the four rods. As the sleeves slide, they push the four support rods downward to rotate and engage with the four mounting brackets for fixed support, thereby increasing the load-bearing capacity of the booms. This makes the lifting device strong in terms of support and load-bearing capacity, preventing the threaded rods from bending, thus ensuring the normal movement of the internal transmission components and providing excellent performance.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Depend on Figures 1 to 4The present invention includes a lifting device body 1. A lifting ring 2 connected to a lifting device is fixedly installed on the top of the lifting device body 1. A support frame 3 is fixedly installed on the bottom of the lifting device body 1. A handwheel 4 is provided below the support frame 3. Hanging rings 5 ​​are provided at both ends of the lifting device body 1. Two steel wire ropes are suspended on the hanging rings 5 ​​for lifting workpieces. Two card seats 6 are fixedly installed on the lower part of both ends of the lifting device body 1. A transmission component is provided on the upper part of the handwheel 4. Lifting arms 15 are provided on both sides inside the lifting device body 1. The ends of the lifting arms 15 that are far apart from each other are fixedly connected to the two hanging rings 5. Support rods 16 are rotatably installed on both sides of the lower part of the two lifting arms 15. The lower ends of the four support rods 16 are adapted to the four card seats 6. The transmission component is connected to the two lifting arms 15 for transmission. When the handwheel 4 rotates, the power is output to the two lifting arms 15 through the transmission component, causing the two lifting arms 15 to move and extend backward, while the four support rods 16 pop out to provide support.

[0020] When hoisting longer items, the operator rotates the transmission assembly by turning the handwheel 4. When the transmission assembly is turned, it drives the two booms 15 to move in opposite directions. When the two booms 15 move in opposite directions, they will drive the two hanging rings 5 ​​to move in opposite directions and extend, thereby increasing the hoisting length.

[0021] As the two booms 15 move in opposite directions, they will drive the four support rods 16 to move. When the lower ends of the four support rods 16 move to the positions of the four brackets 6, the four support rods 16 will rotate downward and be locked into the four brackets 6 for fixed support, thereby improving the load-bearing capacity of the booms 15. This makes the lifting device have a strong support and load-bearing capacity, and will not cause the threaded rods 11 to bend, thus ensuring the normal movement of the internal transmission components and having a very good performance.

[0022] The transmission assembly includes a rotating shaft 7 fixedly mounted on the top of the handwheel 4. The surface of the rotating shaft 7 is rotatably mounted between the support frame 3 and the bottom of the lifting device body 1 via a bushing 8. The top end of the rotating shaft 7 extends into the interior of the lifting device body 1 and is fixedly mounted with a driving bevel gear 26. A driven bevel gear 9 is meshed with one side of the surface of the driving bevel gear 26.

[0023] A shaft 10 is fixedly installed in the middle of the driven bevel gear 9. Threaded rods 11 are fixedly installed at both ends of the shaft 10. The threads of the two threaded rods 11 are opposite in direction. Fixed seats 13 are rotatably installed at both ends of the two threaded rods 11 through shaft seats 12. The bottom of the two fixed seats 13 is fixedly connected to the inner bottom of the lifting device body 1. Threaded sleeves 14 are threadedly connected to the surfaces of the two threaded rods 11. Slider 17 is fixedly installed at the bottom of the two threaded sleeves 14. Slide grooves 18 are provided on both sides of the inner bottom of the lifting device body 1. The two sliders 17 are slidably installed inside the two slide grooves 18, allowing the two sliders 17 to move within the two slide grooves 18.

[0024] The operator rotates the shaft 7 inside the bushing 8 by rotating the handwheel 4. When the shaft 7 rotates, it drives the driven bevel gear 9 to rotate through the driving bevel gear 26. When the driven bevel gear 9 rotates, it drives the two threaded rods 11 to rotate along the two bearings 12 through the shaft rod 10. When the two threaded rods 11 rotate, they drive the two threaded sleeves 14 on their surfaces to move in opposite directions. When the two threaded sleeves 14 move, they drive the slider 17 to slide inside the slide groove 18, which increases the stability of the two threaded sleeves 14 when they move. When the two threaded sleeves 14 move, they drive the two booms 15 to move in opposite directions. When the booms 15 move, they drive the limit blocks 24 to slide inside the limit grooves 25, which increases the stability of the two booms 15 when they move. When the two booms 15 move in opposite directions, they drive the two hanging rings 5 ​​to move in opposite directions and extend, thereby increasing the lifting length.

[0025] A transmission rod 20 is rotatably mounted on the upper side of each of the four support rods 16. Mounting slots 19 are provided on both sides of each of the two booms 15. Sliding sleeves 21 are rotatably mounted on the top of each of the four transmission rods 20. The four sliding sleeves 21 are installed inside the four mounting slots 19, and sliding rods 22 are inserted into the interior of each of the four sliding sleeves 21. The four sliding sleeves 21 can slide along the surface of the four sliding rods 22. The four sliding rods 22 are fixedly installed inside the four mounting slots 19. Springs 23 are sleeved on the surface of each of the four sliding rods 22. The two ends of each spring 23 are fixedly connected to the sliding sleeves 21 and the interior of the mounting slots 19, respectively. Limiting blocks 24 are fixedly mounted on both sides of each of the two booms 15. Limiting slots 25 are provided on the inner walls of both sides of the lifting body 1. The four limiting blocks 24 are respectively opened inside the corresponding limiting slots 25, and the four limiting blocks 24 can move within the corresponding limiting slots 25.

[0026] As the two booms 15 move in opposite directions, they will drive the four support rods 16 to move. When the lower ends of the four support rods 16 move to the positions of the four brackets 6, the springs 23 will push the four sliding sleeves 21 to slide along the surface of the four sliding rods 22. When the sliding sleeves 21 slide, they will push the four support rods 16 downward to rotate and lock into the four brackets 6 for fixed support through the transmission rods 20, thereby improving the load-bearing capacity of the booms 15.
