Embodiment Construction

[0043] The following is attached Figure 1-8 The application is described in further detail.

[0044] The embodiment of the application discloses a prefabricated pile spreader. refer to figure 1 and figure 2, a prefabricated pile spreader, including a fixed sleeve 1 sleeved on the precast pile 4, and a spreader body 2 connected with the fixed sleeve 1, the spreader body 2 is used to lift the precast pile 4. The circumferential direction of the fixed sleeve 1 is evenly provided with several hooks 11. In this embodiment, the number of hooks 11 is set to two, and the number of hooks 11 can also be three or four. Several hooks 11 are arranged along the circumference of the fixed sleeve 1. Arrange evenly. The inside of the fixing sleeve 1 is provided with a clamping mechanism 12 for locking the prefabricated pile 4 , so that the phenomenon of loosening between the fixing sleeve 1 and the prefabricated pile 4 is not easy to occur. The spreader body 2 includes a lifting box 21 ...

Abstract

The invention relates to a precast pile lifting appliance, and belongs to the technical field of mechanical lifting equipment. The precast pile lifting appliance comprises a fixing sleeve and a lifting appliance body connected with the fixing sleeve. The fixing sleeve is provided with multiple hooks, the lifting appliance body is connected with the hooks, the lifting appliance body is provided with an automatic unhooking device, and the automatic unhooking device comprises an unhooking mechanism and a locking mechanism which are connected with each other. When a precast pile is lifted, firstly, the precast pile is sleeved with the fixing sleeve, the fixing sleeve and the precast pile are fixed, then the lifting appliance and the hooks are connected through the locking mechanism, and the precast pile can be lifted through the lifting appliance. After the precast pile is pre-buried in a foundation pit, the hooks and the lifting appliance can be disconnected through the unhooking mechanism, the operation that the lifting appliance is dismounted from the hooks through manual high-altitude operation is not needed, and potential safety hazards caused by high-altitude operation are reduced.

Description

technical field [0001] The present application relates to the technical field of mechanical hoisting equipment, in particular to a prefabricated pile hoisting tool. Background technique [0002] Prefabricated cement piles are referred to as prefabricated piles. Prefabricated piles are suitable for foundation treatment such as silt, silty soil, clayey soil, silt, sandy soil and artificial filling. The main construction method is to use special equipment to drill holes and embed precast piles. pile. [0003] During the construction process of prefabricated piles using the embedding method, the prefabricated piles need to be hoisted. In the related technology, in the process of hoisting the prefabricated pile, first set the fixed sleeve on one end of the prefabricated pile, and fix the fixed sleeve on the prefabricated pile, and then use the spreader to lift the hook on the fixed sleeve, and then the The prefabricated pile is hoisted, inserted into the borehole of the foundat...
