DETAILED DESCRIPTION

[0020] The utility model will be further explained in connection with specific embodiment in the drawings.

[0021] Refer to Figures 1-3 A converter tapping hole sleeve brick transportation and its installation tool, including conveying frame 1, the both sides of one end of conveying frame 1 are equipped with the insertion part 2 for the insertion of mechanical fork truck respectively.The middle part of the other end of conveying frame 1 is fixed with the support rod 4 for the center hole of insertion converter tapping hole sleeve brick 3, and one end of support rod 4 is equipped with conical part 5.The periphery of support rod 4 is equipped with at least three installation slots 6 extending along its axial direction and being arranged uniformly and spacing, and installation slot 6 extends to conical part 5.A plurality of interval arrangement gyro wheel 7 are rotationally arranged in installation slot 6, and the outer edge of gyro wheel 7 is circular arc structure 8.The other end of conveying frame 1 is also equipped with the clamp 9 for locking converter tapping hole sleeve brick 3, and the flexible connecting piece 10 connected clamp 9.

[0022] Specifically, the conveying frame 1 is a rectangular steel plate, the length of which is the distance between the front platform of the converter and the converter, and the rectangular steel plate can transport the whole converter tapping hole brick 3 to the front platform of the converter for installation. The width of the rectangular steel plate is the distance between the two front arms of the mechanical forklift, so that the two front arms of the mechanical forklift are inserted into the insertion part 2, and the conveying frame 1 has a small transverse movement distance (i.e. a small left-right swing distance), and the positioning is better.

[0023] Further, the top surface of the rectangular steel plate is welded with a reinforcing rib 11, which can effectively increase the working strength of the rectangular steel plate, and the rectangular steel plate is not easy to deform, and the weight of the rectangular steel plate is small.

[0024] In the embodiment, the insertion part 2 is a channel steel 12 welded on the top of the conveying frame 1, which has a simple structure and is convenient to process.

[0025] The supporting rod 4 is a circular steel pipe, which can reduce the weight, and the mounting groove 6 is formed by two steel plates 13 welded on the periphery of the circular steel pipe.

[0026] The inner wall of the hoop 9 is provided with a non-slip pad, which can improve the stability of locking the converter tapping hole brick 3.

[0027] In the embodiment, the flexible connecting piece 10 is a chain or a steel wire rope.

[0028] Of course, in other embodiments, the flexible connecting piece 10 can also be a nylon rope or other high-strength rope.

[0029] The supporting rod 4 and the conveying frame 1 are welded, which ensures the connection strength between the supporting rod 4 and the conveying frame 1.

[0030] Working principle:

[0031] First, the two front arms of the mechanical forklift are inserted into the insertion part 2 of the conveying frame 1 and are inserted into position, the mechanical forklift moves the conveying frame 1 to the converter tapping hole brick 3, the supporting rod 4 is aligned with the center hole of the converter tapping hole brick 3, and then the supporting rod 4 is inserted into the center hole of the converter tapping hole brick 3. Due to the existence of the conical part 5, the supporting rod 4 is more convenient to insert into the center hole of the converter tapping hole brick 3. Since the roller 7 and the inner wall of the converter tapping hole brick 3 are in rolling friction, the friction is small, which makes the supporting rod 4 better inserted. After the supporting rod 4 is inserted into position, the flexible connecting piece 10 is tensioned, and the hoop 9 is locked to the converter tapping hole brick 3, so that the converter tapping hole brick 3 will not fall during transportation and installation, and the safety is improved.

[0032] The above are only preferred embodiments of the present application, and it should be pointed out that for those skilled in the art, without departing from the structure of the present application, a number of variations and improvements can be made, which will not affect the effect and practicality of the present application.
