[0021] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine with the embodiments to detail the present application.

[0022] AsFigures 1 to 3 As shown, the multifunctional steel strand threading protection cage of the present utility model includes: a main frame 1, a guiding mechanism 2, lifting lugs 3 and a protection device; the main frame 1 is welded by high-strength steel to form a stable cubic or cylindrical structure, and its size and shape can be adjusted according to actual needs; the guiding mechanism 2 is formed into a conical shape by a wire-releasing framework to ensure that the steel strand can smoothly advance along a predetermined trajectory during the threading process.

[0023] Among them, the surfaces of the main frame 1, the guiding mechanism 2 and the lifting lugs 3 in the protection cage are covered with wear-resistant and corrosion-resistant protective layers, which can effectively resist corrosion and wear in the construction environment. At the same time, wooden blocks are arranged at the bottom and around the main frame 1 to form a protection device, which can reduce the impact of the steel strand on the protection cage.

[0024] Specifically, as Figure 2 shown, the main frame 1 is formed into a cubic structure by 12 main support rods 11 lapped, and the left and right ends of the main frame 1 are further strengthened and fixed by inclined reinforcing braces 12. Four lifting lugs 3 are welded and fixed at the upper end of the main frame 1 to facilitate the lifting of the whole device.

[0025] A rectangular frame for fixedly installing the guiding mechanism 2 is fixed on the front end face or / and the rear end face of the main frame 1. The rectangular frame is formed by lapping two fixed vertical rods 13 and two fixed horizontal rods 14, and the two fixed vertical rods 13 and the two fixed horizontal rods 14 are respectively fixedly connected to the guiding mechanism 2.

[0026] Among them, the main support rods 11, the reinforcing braces 12, the fixed vertical rods 13 and the two fixed horizontal rods 14 can all be made of square steel or U-shaped steel, or two kinds of steel can be used in combination according to the requirements of structural strength.

[0027] As Figure 3 shown, the guiding mechanism 2 is composed of a large iron ring 21, a small iron ring 22 and a number of connecting diagonal rods 23. One end of each connecting diagonal rod 23 is welded to the large iron ring 21, and the other end is welded to the small iron ring 22 to form a conical structure; the diameter of the small iron ring 22 is larger than the diameter of the steel strand 4 to facilitate the wire release of the steel strand 4; the four quadrant points on the large iron ring 21 are respectively welded to the two fixed vertical rods 13 and the two fixed horizontal rods 14 to form a fixed structure.

[0028] Before the steel strand construction, first hoist and place the steel strand coil into the protection cage for fixation, support it with cushion wood and fix it around the protection cage. Then hoist and place the protection cage in front of the structure to be threaded. The steel strand 4 is first released from the inner circle, enters the steel strand threading machine orderly through the guiding mechanism 2, and starts the steel strand threading machine to smoothly pass the steel strand bundle through the reserved hole. After the threading of the current section is completed, it can be hoisted to another section for threading.

[0029] The working principle and process of the multi-functional steel strand threading protection cage of the present utility model are briefly described below.
