Description

Technical Field

[0001] This utility model belongs to the field of building steel structure handling technology, and in particular relates to a hoisting device for assembling building steel structures. Background Technology

[0002] Steel structures refer to structural forms that can bear and transmit loads, made of steel plates and hot-rolled, cold-bent, or welded profiles connected by connectors. During the production of building steel structures, assembly is required, necessitating the use of transportation equipment. Currently, building steel structures are mostly lifted using forklifts or cranes. Forklift handling limits the lifting height of steel structures, failing to meet the actual assembly needs. Furthermore, cranes using wire ropes to lift hooks are prone to swaying, making positioning during assembly difficult and posing a significant challenge to crane operators. Therefore, current technologies for assembling and lifting building steel structures are inconvenient, have difficulty adjusting the angle of the steel structure during assembly, are inefficient, and prone to swaying and other technical problems. Utility Model Content

[0003] To address the technical problems of swaying and low assembly efficiency in existing steel structure hoisting, this utility model provides a hoisting device for assembling building steel structures. The device includes a trolley body, which comprises a trolley frame. Both ends of the trolley frame are equipped with a trolley traveling mechanism to facilitate frame movement. The trolley traveling mechanism includes trolley wheels and a trolley traveling motor. The trolley wheels are rotatably mounted on the trolley body, and the trolley traveling motor is fixed to the trolley frame, with its power output shaft connected to the trolley wheels. A laterally movable trolley is located at the top of the trolley body. A lifting mechanism is mounted at the top of the trolley, comprising a lifting drum, a lifting motor, and a reducer. The lifting drum is rotatably mounted on the trolley, and the lifting motor is connected to the lifting drum via the reducer. When the lifting motor is started, it drives the lifting drum to rotate, and the lifting drum pulls the load by winding or releasing a steel wire rope. The trolley is equipped with a trolley travel mechanism for easy movement. This mechanism includes trolley wheels and a trolley travel motor. The wheels are rotatably mounted on the trolley, while the motor is fixed to it, with its power output shaft connected to the wheels. Below the trolley are an upper support frame and a lower support frame. The upper support frame includes four vertically arranged rectangular support tubes, the tops of which are detachably fixed to the bottom of the trolley. The lower support frame includes four vertically arranged support rods, the upper ends of which are slidably mounted inside the support tubes, which serve as guides. Below the support rods is a horizontally arranged upper support platform. The bottom ends of the four support rods are fixed to the top of the upper support platform. The top of the upper support platform has two symmetrically arranged pulley assemblies. Each pulley assembly includes a pulley bracket fixed to the top of the platform, with several pulleys rotatably mounted on the bracket via a support shaft. The pulleys are connected to a lifting drum of a hoisting mechanism via steel wire ropes. The rotation of the hoisting drum pulls the upper support platform vertically via the steel wire ropes. A slewing mechanism is provided between the upper and lower support platforms. This mechanism includes a support plate fixed to the bottom of the upper support platform, with a circular travel track on the plate. Below the support plate is a horizontally positioned lower support platform. Several fixed plates are fixed to the top edge of the lower support platform, arranged circumferentially. Traveling wheels are rotatably mounted on the top of each fixed plate, rolling onto the travel track. Starting the slewing motor rotates the lower support platform, facilitating adjustment of the angle of the support below. A support mechanism for supporting the steel structure is located at the bottom of the lower support platform. A vertically aligned rotating shaft is fixed to the lower support platform, coaxial with the platform. A vertically aligned slewing motor is fixed to the top of the upper support platform, with its power output shaft connected to the rotating shaft. A pulley assembly is connected to the lifting mechanism via a wire rope.

[0004] Preferably, the support mechanism includes a support horizontally disposed below the lower support platform, and several vertically disposed columns are fixed between the support and the lower support platform, with the right end of the support extending to the right out of the lower support platform.

[0005] Preferably, the top of the support is provided with several evenly arranged anti-slip protrusions, and several spaced and vertically arranged baffles are fixed on both the front and rear sides of the support.

[0006] Preferably, a support plate for fixing is provided between each adjacent support tube of the upper support frame.

[0007] The above-mentioned approach has the following advantages:

[0008] The upper and lower support frames are designed with a steel wire rope traction pulley assembly, allowing the support rod to slide up and down along the support tube. This adjusts the height of the lower support platform and prevents the steel wire rope from swaying, enhancing the stability and safety of the support when hoisting steel structures. The slewing mechanism, driven by a slewing motor, rotates the lower support platform, facilitating angle adjustment and steel structure installation. Simultaneously, the traveling wheels roll along the track at the top of the support plate, enhancing stability. The trolley body facilitates longitudinal movement of the trolley.
