Technical Field

[0001] The invention relates to the technical field of residential construction hoisting, in particular to a residential construction hoisting device. Background Art

[0002] Hoisting refers to the general term for the installation and positioning of equipment by cranes or lifting mechanisms. During the inspection or maintenance process, various hoisting machines are used to lift equipment, workpieces, tools, materials, etc. to change their position. Hoisting devices refer to devices that mechanically drive objects to move vertically. They are widely used in many fields, especially in the construction field. In the process of building construction, it is often necessary to transport heavy and large objects to higher places. Therefore, prefabricated building construction hoisting devices are very practical facilities.

[0003] However, in the existing technology, most of the small fixed cranes used for hoisting construction materials are small fixed cranes. When decorating a house, sand, cement bags and gravel need to be hoisted. However, the existing hoisting devices are installed on the roof of the house. However, the existing hoisting construction materials do not have an automatic rotation function after hoisting, and the hoisted construction materials cannot be rotated and hoisted to the specified position. The boom of the small fixed hoisting device cannot be locked and rotated at will, and the existing hoisting device still requires the staff to reach out and drag the hoisted construction materials after hoisting the construction materials.

[0004] Therefore, we need a residential construction hoisting device to solve the problem of automatic rotation of the boom of the existing construction hoisting device, and also to lock the hoisting position of the boom of the construction hoisting device. Summary of the invention

[0012] Preferably, the slot is arranged in a "concave" shape, the depth of the slot is equal to the width of the clamping strip, two clamping strips are arranged, and the two clamping strips are symmetrically arranged along the center point of the rotation axis.

[0013] Preferably, an integrally formed fixed shaft is arranged at the top of the rotating shaft, the surface of the fixed shaft at the top of the rotating shaft is fixedly connected to the bottom turntable of the boom, and the cross-section of the fixed shaft at the top of the rotating shaft is arranged in an "I" shape.

The top of the supporting column of the frame cannot rotate, so the lifting position of the construction materials hoisted by the hook at the end of the boom is locked. When the micro hydraulic cylinder contracts, the stabilizing plate will automatically drop inside the supporting column of the hanging frame due to gravity. Therefore, the inner ring teeth of the rotating gear ring engage the surface of the driving tooth, so that the rotating shaft rotates in the supporting column of the hanging frame. The rotating gear ring rotates inside the stabilizing plate, so that the rotating gear ring can charge and drive the tooth to drive the rotating shaft to automatically rotate in the supporting column of the hanging frame. Therefore, the construction materials hoisted at the end of the boom can be automatically rotated to the designated hoisting position, and the staff does not need to manually drag the construction materials hoisted by the hook of the boom.
