Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, specifically a small steel component hoisting device. Background Art

[0002] Small steel component hoisting devices are a widely used tool in the construction industry.

[0003] Common small steel component hoisting devices are mostly mechanized devices that use motors to drive lifting and hoisting. One problem is that traditional hoisting devices often can only achieve a single lifting function, making it difficult to accurately hoist and position steel components. In addition, many hoisting devices lack flexibility in the design of double-arm hoisting mechanisms, failing to meet the hoisting needs of steel components of different sizes and shapes. To overcome these problems, there is an urgent need in the market for a small steel component hoisting device that can simultaneously achieve lifting and flexible double-arm hoisting. This device needs to be compact in structure, easy to operate, and have high hoisting accuracy to meet the construction industry's demand for efficient and accurate hoisting operations. Therefore, the development of a new type of small steel component hoisting device is particularly important. Utility Model Content

[0026] Please see Figure 1-3 A small steel component hoisting device includes a base 1, an H-shaped support frame 4, a first motor 6, a first rotating shaft 7, a threaded column 8, a lifting box 9, and a double-arm hoisting mechanism. Two symmetrically distributed H-shaped support frames 4 are fixed on the top surface of the base 1. The first motor 6 is located on the top surface of the base 1 between the two H-shaped support frames 4. The output end of the first motor 6 is fixed with the first rotating shaft 7. The end of the first rotating shaft 7 away from the first motor 6 is fixed with the threaded column 8. The lifting box 9 is arranged around the threaded column 8. The double-arm hoisting mechanism is arranged on the top surface of the lifting box 9.

[0027] The double-arm hoisting mechanism includes a hoisting box 13, a boom 14, a rack 15, a gear 18, a second motor 19, and a second rotating shaft 20. The hoisting box 13 is fixed to the top surface of the lifting box 9. The boom 14 is arranged inside the hoisting box 13 with opposite directions. A rack 15 is fixed to one side of the two booms 14. A gear 18 corresponding to the rack 15 is arranged between the two racks. The second rotating shaft 20 is inserted and fixed in the middle of the gear 18. The second motor 19 is arranged at one end of the second rotating shaft 20.

[0028] In this embodiment, the hoisting box 13 is hollow, and the two hollow sides of the hoisting box 13 are close to the two H-shaped support frames 4 respectively. The two lifting arms 14 are arranged inside the hoisting box 13 from top to bottom. This design not only reduces the overall weight, but also cleverly utilizes the internal space to install the lifting arms 14 and their drive mechanism, thereby improving the integration of the device. The side of the lifting arm 14 near the gear is fixed with limit blocks on both sides of the rack 15.

[0029] In this embodiment, the second motor 19 is located on the outside of the hoisting box 13 perpendicular to the central axis of the gear 18. One end of the second rotating shaft 20 is fixed to the output end of the second motor 19, and the other end of the second rotating shaft 20 passes through the side of the hoisting box 13 and is fixed with the gear 18. This design ensures the continuity and stability of power transmission and provides a reliable power source for the flexible sliding of the boom 14.

[0030] In this embodiment, two sets of pulleys 17 are fixed at the top and bottom of the hoisting box 13. The two booms 14 are provided with a first groove 16 corresponding to the pulleys 17 on the side away from the gear 18. The two sets of pulleys 17 are slidably connected in the other first groove 16. The pulleys 17 can slide smoothly along the first groove 16, which reduces the friction and resistance of the boom 14 during the sliding process, and improves the accuracy and stability of the sliding, thereby extending the service life of the boom 14.

[0031] In this embodiment, a motor mounting shell 5 is fixed to the outer periphery of the first motor 6 at the center of the top surface of the base 1. The first rotating shaft 7 passes through the top surface of the motor mounting shell 5 and the bottom surface of the lifting box 9 and is fixed to the center of the bottom surface of the threaded column 8. The inner wall of the lifting box 9 is provided with a thread 10 corresponding to the threaded column 8. The cooperation between the thread 10 on the inner wall of the lifting box 9 and the threaded column 8 realizes the lifting function. This design is simple and effective, and provides reliable support for the lifting operation of the device.

[0032] In this embodiment, sliders 11 are fixed on both sides of the lifting box 9 near the two H-shaped support frames 4. The two H-shaped support frames 4 are provided with a second slide groove 12 corresponding to the sliders 11 on opposite sides. The two sliders 11 are respectively inserted into the two second slide grooves 12.

[0033] In this embodiment, an array of fixing blocks 2 are fixed on the bottom surface of the base 1, electric wheels 3 are installed on both sides of the fixing blocks 2, and electric winding wheels 21 are fixed on the bottom surface of the two booms 14 away from the gear 18. A steel component basket 22 is tied to the two ropes that lock the electric winding wheels 21.

[0034] Beneficial effects:

[0035] This type of small steel component hoisting device achieves lifting function by driving the threaded column 8 with the thread 10 on the inner wall of the lifting box 9 through the first motor 6. The double-arm hoisting mechanism uses the second motor 19 to drive the gear 18 to mesh with the rack 15, so that the boom 14 slides in the hoisting box 13 to achieve flexible hoisting. The design of the pulley 17 and the first slide groove 16 enhances the stability of the boom 14's movement. The cooperation between the slider 11 and the second slide groove 12 ensures the smooth lifting of the lifting box 9. The electric wheel 3 facilitates the movement of the device. The electric winding wheel 21 cooperates with the hoisting rope to safely hoist the steel component basket 22. The overall structure is compact, the operation is simple, and the hoisting efficiency and accuracy are improved.

[0036] Working principle:

[0037] First, the electric wheel 3 on the bottom of the base 1 is used to move the small steel component to the designated position and place it into the basket 22. Then, the first motor 6 is started, and its output end drives the first rotating shaft 7 to rotate, which in turn drives the threaded column 8 to rotate. Since the thread 10 on the inner wall of the lifting box 9 cooperates with the threaded column 8, the lifting box 9 will rise and fall along the threaded column 8. At the same time, the sliders 11 on both sides of the lifting box 9 slide in the second slide groove 12 to ensure a smooth lifting process. After the lifting reaches a suitable height, the second motor 19 of the double-arm hoisting mechanism is started, and its output end drives the second rotating shaft 20 to rotate, which in turn drives the gear 18 to rotate. The gear 18 meshes with the racks 15 on the two booms 14, so that the booms 14 slide and unfold in the hoisting box 13. The pulley 17 slides in the first slide groove 16 to enhance stability. After the booms 14 are unfolded, the electric winding wheel 21 on the bottom of the booms 14 is started to release or tighten the hoisting rope, and the steel component basket 22 is safely hoisted to the target position. The whole process is compact in structure and easy to operate, effectively improving hoisting efficiency and accuracy.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
