Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a hoisting device for building construction materials. Background Technology

[0002] Construction sites often require frequent movement of various building materials and tools from lower to higher locations to ensure smooth construction. Therefore, efficient, safe, and flexible hoisting equipment is crucial for improving both the efficiency and quality of building construction.

[0003] Existing hoisting devices for building construction lack flexibility and convenience in height adjustment. They typically struggle to accurately and quickly adjust to the diverse hoisting height requirements of different construction scenarios, necessitating additional time and effort to modify the device or utilize auxiliary equipment when facing work surfaces at varying heights, significantly impacting construction efficiency. Regarding the adjustment of the support arm angle, existing devices are cumbersome to operate, failing to achieve flexible and precise angle changes and fixation, thus failing to adequately meet the needs of hoisting at different angles in building construction and limiting their application range. Furthermore, in terms of movement and fixation, existing hoisting devices are either inconvenient to move, requiring multiple people to assist in handling, consuming significant manpower; or, once in the work area, they are difficult to securely fix, easily shifting during hoisting due to external forces or their own unstable center of gravity, affecting the normal progress of hoisting operations. Therefore, those skilled in the art have provided a hoisting device for building construction to solve the problems mentioned in the background art. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a hoisting device for building construction materials. This device solves the problems of fixed height and angle, as well as issues with movement and fixation. Existing hoisting devices are either inconvenient to move, requiring multiple people to cooperate in handling and consuming a lot of manpower, or they are difficult to fix stably after arriving at the work area, and are prone to movement during hoisting due to external forces or their own unstable center of gravity, affecting the normal progress of hoisting operations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hoisting device for building construction materials, comprising a trolley, a fixed sleeve on the trolley, a motor inside the fixed sleeve, a screw connected to the upper output end of the motor, a moving rod above the motor, a vertically threaded groove inside the moving rod, an arc-shaped limiting plate installed on one side of the upper end of the moving rod, a third positioning hole on the arc-shaped limiting plate, a support arm rotatably connected to the upper end of the moving rod, a screw hole opened at the end of the support arm facing the arc-shaped limiting plate, a bolt threaded into the screw hole, a winding unit installed on the trolley, casters installed on the bottom side of the trolley, a hydraulic rod on one side of the casters, and a support plate installed at the bottom output end of the hydraulic rod.

[0006] Furthermore, a screw is installed at the bottom port of the fixing sleeve, and the fixing sleeve is fixedly connected to the trolley by the screw.

[0007] Furthermore, the movable rod is slidably sleeved with the fixed sleeve, and the screw is threadedly sleeved with the threaded groove. The height of the movable rod can be adjusted by driving the screw to rotate through a motor.

[0008] Furthermore, a first positioning hole is provided on one side wall of the upper end of the fixed sleeve, and a second positioning hole is provided on the side of the moving rod facing the first positioning hole. The first positioning hole and the second positioning hole are inclined. A plug rod is inserted into the first positioning hole. The plug rod passes through the first positioning hole and the second positioning hole and is inserted into them. By passing through the first positioning hole and the second positioning hole in sequence, the height of the moving rod is fixed again, thereby increasing the stability of the moving rod.

[0009] Furthermore, the bolt passes through the third positioning hole and is threaded into the screw hole. When it is necessary to adjust the angle of the support arm, the bolt can be unscrewed, the support arm can be rotated, and after the angle of the support arm changes, the bolt can be re-threaded through the third positioning hole and reconnected to the screw hole on the support arm, thereby fixing the support arm and achieving the fixing effect after the angle is changed. Beneficial effects

[0010] This device, through the cooperation of a motor, screw, and moving rod, allows for convenient adjustment of the moving rod's height, thereby flexibly adjusting the equipment's lifting height to meet different lifting needs. An arc-shaped limiting plate with a third positioning hole is installed on one side of the upper end of the moving rod. The support arm is rotatably connected to the moving rod, with a threaded hole at one end. The angle of the support arm can be easily adjusted and fixed by the cooperation of bolts with the third positioning hole and threaded hole, adapting to lifting operations at different angles. Universal wheels are installed at the bottom of the trolley for easy movement, allowing the equipment to be flexibly transferred to different working positions. A hydraulic rod and support plate are installed on one side of the universal wheels. After the trolley arrives at the working area, the hydraulic rod extends and retracts, lifting the trolley through the support plate, effectively preventing the trolley from moving during lifting and ensuring a stable and reliable lifting process.

Bolt 9 passes through the third positioning hole 701 and is threadedly connected to the screw hole 801. When it is necessary to adjust the angle of the support arm 8, the bolt 9 can be unscrewed and the support arm 8 can be rotated. After the angle of the support arm 8 is changed, the bolt 9 is re-inserted through the third positioning hole 701 and connected to the screw hole 801 on the support arm 8, thereby fixing the support arm 8 and achieving the fixing effect after the angle is changed.

[0020] The working principle of this device is as follows: A fixed sleeve 2 is installed on the trolley 1 by screws 3. A motor 4 and a moving rod 6 are housed inside the fixed sleeve 2.

After the angle of the support arm 8 is changed, the bolt 9 is re-passed through the third positioning hole 701 and connected to the screw hole 801 on the support arm 8, thereby fixing the support arm 8 and achieving the fixing effect after the angle is changed.
