Description

Technical Field

[0001] The utility model relates to the field of steel structure hoisting construction, in particular to a non-detachable shackle suitable for hoisting of steel columns. Background Art

[0002] Traditional method: When lifting a steel column, the lifting wire rope and the column are connected together through a shackle, and the shackle screw is connected to the U-shaped piece through a thread. When dismantling at a high place, manual dismantling is required. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a non-detachable shackle suitable for steel column hoisting, which is convenient for ground operators to complete the separation of the shackle and the steel column lifting ear.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A shackle suitable for lifting steel columns, comprising a U-shaped lifting ring and a lifting rod, characterized in that a sleeve that can be inserted into the lifting rod is fixed to each of the two ends of the U-shaped lifting ring, a guide tube is connected to one of the sleeves, and a limit plate is welded inside the guide tube; the lifting rod comprises a main body and an enlarged end, the main body of the lifting rod can be inserted into the sleeve, the enlarged end is located in the guide tube and constrained in the limit plate; a pull rope is connected to the enlarged end of the lifting rod, the pull rope passes through the reserved hole on the limit plate, and then hangs down and is controlled by the lifting personnel.

[0006] A connecting hole is arranged on the enlarged end, and the drawstring is fixed on the connecting hole.

[0007] A fixed pulley is also installed at the pipe mouth of the guide pipe, and the pulling rope hangs down after passing through the fixed pulley.

[0008] The guide tube is detachably connected to the sleeve ring.

[0009] The guide tube is connected to the collar in a threaded or lockable manner.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model installs a guide rod on a collar on one side, connects a pull rope to the boom, and allows the boom to slide in the guide tube by the hoisting personnel on the ground, so that the boom passes through the lifting lug of the steel column, and the shackle is separated from the lifting lug of the steel column. The operator does not need to work at high altitude, and the operation is simple and safe.

[0012] The limit plate on the guide rod can prevent the boom from falling from a high altitude when it slides along the guide tube.

[0013] The fixed pulley installed in the guide tube cleverly converts the downward pulling force into a horizontal force for the sliding of the boom, which not only improves the efficiency of the operator's pulling rope, but also protects the pulling rope and increases its life. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 2 It is a structural schematic diagram of the utility model suspension rod. DETAILED DESCRIPTION

[0016] The utility model is described in detail below in conjunction with the accompanying drawings:

[0017] A non-detachable shackle suitable for lifting steel columns, such as Figure 1 As shown, it includes a U-shaped lifting ring 1, a lifting rod 2 and a pull rope 3; a sleeve 7 that can be inserted into the lifting rod 2 is fixed at each end of the U-shaped lifting ring 1, and a guide tube 4 is also connected to one of the sleeves, and a limit plate 5 is welded inside the guide tube 4. The lifting rod 2 includes a main body 21, an enlarged end 22 and a connecting hole 23. The main body of the lifting rod can be inserted into the sleeve 7, and the enlarged end is located in the guide tube 4 and constrained in the limit plate 5. A fixed pulley is also installed at the pipe mouth of the guide tube 4. The pull rope 3 is connected to the connecting hole 23 of the lifting rod 2, and passes through the reserved hole of the limit plate 5, bypasses the fixed pulley, and then hangs down, and is controlled by the lifting personnel.

[0018] The guide tube 4 and the collar 7 are connected by welding or a detachable connection such as a threaded connection. The purpose of the detachable connection is to facilitate the removal of the suspension rod 2 from the lifting ring 1 and the replacement of the pull rope 3.

[0019] The steps for using the non-detachable shackle of the utility model suitable for steel column hoisting are as follows:

[0020] (1) The lifting wire rope 8 passes through the U-shaped lifting ring 1;

[0021] (2) Install the pull rope 3 on the boom 2, and install the boom 2 in the guide tube 4;

[0022] (3) The suspension rod 2 passes through the lifting lug 9 of the steel column and the sleeve 7 on the other side in sequence;

[0023] (4) The steel columns are hoisted into place;

[0024] (5) After the hoisting is in place, the hoisting wire rope 8 is moved downward, and the hoisting rod 2 and the U-shaped hoisting ring 1 are loosened;

[0025] (6) The ground hoisting personnel pull the pull rope 3 to separate it from the steel column lifting ear 9;

[0026] (7) Adjust the U-shaped lifting ring to the ground for subsequent operations.
