As the main vertical transportation equipment, the unloading platform within the hoisting radius of the tower crane plays the role of a transfer hub for building materials and construction equipment. The currently commonly used cantilever unloading platform system has significant technical defects: when materials are hoisted to the platform, they need to be manually transferred from the edge area to the internal working surface of the building through secondary handling. This transfer process has multiple safety hazards and efficiency bottlenecks. At the same time, operators need to carry out material handling at the unenclosed floor edge, posing a risk of falling from a height.

[0003] The prior art, such as the utility model patent of 202120702322.6, discloses a building construction material lifting device, including a bracket, a sliding frame, and a material box. A fastening bolt is provided on one side of the bracket, an operation panel is provided at the upper end of the bracket, a motor is provided between the brackets, and a winding tube is provided at the power output end of the motor. The beneficial effects are as follows: through the sliding frame, connecting plate, fixed cylinder, support rod, and bracket provided in the present utility model, the split installation can be adopted to realize the free and rapid splicing of the device, ensuring the efficient progress of building construction work and meeting the use requirements of the device on buildings of different heights. Through the material box, discharge port, and pull plate provided, the materials in the material box can be quickly poured out completely, thereby improving the work efficiency of building construction. Although this structure can realize the lifting of materials, it has defects when transferring to the floor and requires manual operation, with a low safety factor.

[0004] Based on this, it is necessary to study a material lifting device for building construction. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a material lifting device for building construction, which effectively solves the problems that the existing material lifting structure has difficult lifting and transferring operations to the floor and low safety factor.

In a specific implementation structure, the trigger device 4 includes a trigger seat 41, a trigger rod 42, a positioning seat 45, a spring 44 and a lifting seat 46; the trigger seat 41 is fixed at the floor 1. During implementation, the trigger seat 41 can also be fixed at the bottom area of the docking track 31, and its upper part avoids the traveling space of the moving wheels. When implementing the trigger seat 41, it can be fixed at the corresponding docking track 31 separately, or fixed on the docking track 31 by clamping, top mounting or other detachable methods.
