High-strength screw special spreader for fan foundation of tension-free cast-in-place pile

Abstract

The invention discloses a high-strength screw rod dedicated hoisting tool of a tension-free cast-in-place pile fan foundation, which solves the problems that the working efficiency of hoisting a high-strength screw rod of an existing tension-free cast-in-place pile wind power generator foundation is low and a screw buckle of the high-strength screw rod is easy to damage. The high-strength screw rod dedicated hoisting tool comprises a rectangular hoisting plate base (9); the high-strength screw rod dedicated hoisting tool is characterized in that the front side edge of the rectangular hoisting plate base (9) is provided with U-shaped grooves (8) at intervals, the front side of the top surface of the rectangular hoisting plate base (9) is provided with an inserting plate (2) with an inserting hole, the rear side of the top surface of the rectangular hoisting plate base (9) is provided with a high-strength screw rod nut supporting plate (5), the rectangular hoisting plate base (9) is provided with two hoisting lug plates (1) and two hoisting rings (7), the front side edge at the right end of the rectangular hoisting plate base (9) is provided with a plug pin locking groove (10), and a pin shaft of an L-shaped plug pin (6) is movably inserted in the inserting hole of the inserting plate (2). The high-strength screw rod dedicated hoisting tool disclosed by the invention has the advantages that the construction is simple, and the use is convenient; and the working efficiency of hoisting is increased.

Description

technical field [0001] The invention relates to a hoisting tool, in particular to a hoisting tool for a group of high-strength screw rods used for cast-in-situ piles. Background technique [0002] The tension-free cast-in-situ pile wind turbine foundation of the power plant has the characteristics of shorter construction time and lower cost than the general gravity expansion foundation, and is now widely used and promoted. In the construction of the foundation of wind power generators with tension-free cast-in-place piles, the high-strength screws must be hoisted into the foundation pit with a crane. Wear PVC sleeve pipe after carrying out one by one separation again, there is work efficiency low, especially the problem that easily damages the turnbuckle of high-strength screw rod in the hoisting process. Contents of the invention [0003] The present invention provides a high-strength screw special spreader for the foundation of a non-tension cast-in-place pile for wind ...
