Description

TECHNICAL FIELD

[0001] The utility model relates to hoist technology field, concretely is a kind of prefabricated well shaft hoist device. BACKGROUND

[0002] With the improvement of assembly type building technology, the well shaft, well chamber and other structures in the drainage engineering field are usually installed and constructed using prefabricated structures. The well chamber is usually hoisted using embedded lifting rings, while the well shaft cannot be hoisted using devices such as embedded lifting rings in advance due to structural reasons. For example, a well shaft with an inner diameter of 700 mm has a conventional size of 700*300 mm, 700*500 mm or 700*1000 mm, and its theoretical weight is 106.5 Kg, 177.4 Kg or 356.9 Kg, respectively. It is difficult to complete the transportation and installation manually, and it is usually hoisted and installed after being tied with a steel wire rope (or a hoisting belt). Although this method can complete the installation work, the tying is a manual operation, and the hoisting balance point is not easy to control, making it difficult to ensure the stable and horizontal completion of the well shaft installation. In general, one side is in contact with the mortar first, and then the other side is gradually positioned and in contact with the mortar to complete the installation. Due to uneven pressure distribution during the installation process, the side that is in contact with the mortar first may have insufficient mortar and a large installation gap after the installation is completed, making it difficult to control the construction quality. Therefore, we propose a prefabricated well shaft hoist device to assist in well shaft installation and construction. SUMMARY
