[0016] Figure 1 is a structural schematic view of the utility model; DETAILED DESCRIPTION

[0017] In order to more clearly illustrate the technical scheme in the embodiments of the utility model or the prior art, the specific implementation manner of the utility model will be described below with reference to the drawings. Obviously, the drawings described below are only some embodiments of the utility model, and for those skilled in the art, other drawings can be obtained according to these drawings without creative labor, and other implementation manners can also be obtained.

[0018] As shown in Figure 1 A tuyere blowpipe replacement tool has the following structure:

[0019] The bottom plate 1 is provided with a roller (which can not be installed) at the bottom, and the bottom plate is a rectangular plate fixed on a lifting mechanism, and the lifting mechanism is provided with traveling wheels at the bottom.

[0020] The upper end surface of the bottom plate is fixedly provided with a front support frame and a rear support frame.

[0021] The front support frame and the rear support frame are fixedly provided with a support leg seat for supporting the tuyere blowpipe support leg.

[0022] To ensure the supporting effect, the end of the bottom plate close to the rear support frame is fixedly provided with a vertical plate 2, the two ends of the vertical plate extend from the two sides of the bottom plate to form an extending section 21, the extending section is fixedly connected with a horizontal plate 3 for supporting the supporting leg, and the end of the vertical plate is fixedly connected with the rear end of a side baffle 4, and the side baffle is fixedly connected with the horizontal plate.

[0023] The horizontal plate is fixedly provided with a rectangular reinforcing plate 5, and the two sides of the reinforcing plate are fixedly connected with the side baffle and the vertical plate, so as to improve the strength of the supporting leg base.

[0024] The vertical plate (extending section), the side baffle, the horizontal plate and the reinforcing plate form the supporting leg base.

[0025] Correspondingly, the vertical plate can only have the extending section and does not need to be located on the part directly above the bottom plate, and the structure has the disadvantage of low connection strength and relatively low service life, but does not affect the normal use, and the structure has a higher operation requirement in the use process and needs to accurately align the supporting leg with the supporting leg base. The vertical plate structure can play a role similar to a backer, and is more convenient to align and adjust.

[0026] The rear support frame comprises a rear vertical plate 6 and an H-shaped steel 7 fixed to the front end face of the rear vertical plate, the upper end of the rear vertical plate has a circular arc groove 8 matched with the tuyere blowing pipe, and the height of the H-shaped steel is lower than the height of the lowest point of the circular arc groove.

[0027] The H-shaped steel is located at the center of the bottom plate and is fixedly connected with the bottom plate at the bottom, and is fixedly connected with the rear vertical plate at the rear side.

[0028] The front support frame comprises a front vertical plate and a front reinforcing plate 9 fixedly connected with the front vertical plate, so as to improve the strength of the front vertical plate, the front vertical plate comprises a first front vertical plate 10 and a second front vertical plate 11, the front end of the front reinforcing plate is fixedly connected with the first front vertical plate, and the rear end is fixedly connected with the second front vertical plate.

[0029] The upper end of the first front vertical plate and the second front vertical plate also has an arc-shaped groove matched with the tuyere blowing pipe, the height of the first front vertical plate is higher than the height of the second front vertical plate, and is used for matching the shape that the inner diameter of the flange end of the tuyere blowing pipe becomes smaller, and the tuyere blowing pipe flange end is supported by the first and second front vertical plates, so as to cope with the problem of thick and heavy flange end.

[0030] The rear end face of the rear vertical plate is fixedly provided with a push hand assembly, the push hand assembly comprises a first L-shaped rod 11 and a second L-shaped rod 12 fixedly provided on the rear end face of the rear vertical plate, the first L-shaped rod and the second L-shaped rod are symmetrically arranged and fixedly connected through a cross rod 13.

[0031] The bottom plate is fixed on a jack serving as a lifting mechanism, and the bottom of the jack has a traveling wheel.

[0032] The gap is formed between the rear ends of the first L-shaped rod and the second L-shaped rod, which is convenient for folding when the jack is not used, and the pressing rod is located in the area surrounded by the first L-shaped rod and the second L-shaped rod when the jack is not used, and the gap is used for the up and down movement of the pressing rod when the jack is used.

[0033] The bottom plate can be lifted, the height of the front support frame is reduced, and the front support frame is convenient to withdraw from between the support feet.

[0034] It should be noted that the above embodiments can be freely combined as needed. The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should be considered as the protection scope of the present application.
