Description

Technical Field

[0001] This utility model relates to the field of building material hoisting technology, and in particular to a simple building material hoisting device. Background Technology

[0002] In the construction process, the vertical and horizontal transportation of building materials is an essential part, especially the hoisting of heavy objects such as bricks, mortar, steel bars, and precast components. Traditional material handling methods mainly rely on manual labor or simple mechanical assistance, but these methods suffer from low efficiency, high labor intensity, and numerous safety hazards. As the construction industry develops towards higher efficiency and mechanization, the application of simple hoisting devices has become an important means to improve construction efficiency and reduce labor costs. While workers can transport materials by carrying them on their shoulders, lifting them by hand, or using handcarts, this method is suitable for small-scale projects but is inefficient and prone to causing muscle strain. Temporary scaffolds made of steel pipes or wood, combined with manual hoists, are suitable for low-rise buildings, but their stability and safety are poor. Therefore, we have redesigned a simple hoisting device for building materials. Utility Model Content

[0010] Compared with related technologies, the simple hoisting device for building materials provided by this utility model has the following advantages: 1. This utility model provides a simple hoisting device for building materials. After the building materials to be hoisted are placed on the material placement platform and fixed, the drive motor controls the rotation of the drive threaded rod, causing the sliding limit plate to move axially along the threaded rod. This increases the distance between the two sliding connecting plates and the angle between the two hoisting steel ropes, ensuring the stability of the material placement platform and providing more space above the platform for easier material placement. Furthermore, when the material placement platform is idle or has only a small amount of material, the two sliding connecting plates can be moved closer together to reduce the angle between the two hoisting steel ropes, preventing interference between the hoisting steel ropes and other equipment in the environment. The roller drive motor drives the winding roller to rotate, synchronously winding and unwinding the hoisting steel ropes to achieve hoisting control. The synchronous operation of the two winding rollers ensures uniform force on the hoisting steel ropes, preventing the material placement platform from tilting and ensuring a smooth material hoisting process.

[0011] 2. This utility model provides a simple hoisting device for building materials. The movable auxiliary handle, in conjunction with omnidirectional casters, facilitates the overall movement of the device, improving operational flexibility. Material limiting straps are used to secure the materials; their pin heads can be inserted into pin slots, and by aligning the first and second locking connection holes, the pin head is inserted into the pin device, completing the locking between the pin head and the pin disc. Multiple sets of material limiting straps work together to ensure the materials are firmly fixed, preventing materials from falling during hoisting and significantly improving the safety of the device.

[0015] In the implementation plan, after the building materials to be lifted are placed on the material placement platform 12 and fixed, the drive motor 4 controls the rotation of the drive threaded rod 6, which drives the sliding limit plate 7 to move along the axial direction of the threaded rod, thereby adjusting the distance between the sliding connecting plates 8 on both sides and ensuring the stability of the material placement platform 12. The roller drive motor 13 drives the winding roller 9 to rotate, synchronously winding and unwinding the lifting steel rope 11 to achieve lifting control. The synchronous operation of the winding rollers 9 on both sides ensures that the lifting steel rope 11 is subjected to uniform force, avoids tilting of the material placement platform 12, and ensures a smooth material lifting process.
