Description

Small-sleeve spherical protector Technical Field The utility model relates to the technical field of tuyere small sleeve installation, in particular to a small sleeve spherical protector. Background The blast furnace tuyere small sleeve is an important device in a blast furnace air inlet system, and in the working process, hot air passes through the tuyere small sleeve and is fed into a blast furnace, and because of the special working environment of high temperature and high heat, the tuyere small sleeve is extremely easy to damage and needs to be replaced periodically. In the prior art, firstly, a plurality of enterprises cannot use auxiliary equipment because the platform space of an air inlet is insufficient, the air inlet small sleeve can only be manually conveyed to be installed, in the installation process, after the air inlet small sleeve is penetrated into the air inlet, the air inlet small sleeve is impacted by the impact rod to be fixed by the impact rod, in the traditional installation mode, the damage to the scratches of the spherical surface of the inner wall of the small sleeve is easily caused during the impact to influence the service life of the small sleeve, secondly, a plurality of auxiliary equipment do not have the function of adjusting the supporting device, so that one equipment can only adapt to the air inlet small sleeve with one size, the working efficiency is influenced, and the working cost is increased. Therefore, a small spherical protector needs to be designed in the current environment to solve the technical problems in the background technology. Disclosure of utility model The utility model provides a small spherical protector for solving the technical problems in the background technology. The utility model provides a small sleeve spherical protector, which comprises a guide shaft, a protection plate, an adjusting component for adjusting the position and a supporting component for supporting and fixing an air port small sleeve, wherein the protection plate is arranged on the guide shaft, the adjusting component is installed at one end of the guide shaft, which is close to the protection board, the supporting component is installed on the guide shaft, and the supporting component is connected with one end of the protection board. Optionally, threads are arranged at two ends of the guide shaft. Optionally, the adjusting component comprises a knob and a limiting step, the knob is installed at one end of the guide shaft, which is close to the protection plate, the limiting step is installed on the guide shaft, and one end of the limiting step is connected with the protection plate. Optionally, the support assembly includes rotation sleeve, screw thread sleeve, is used for adjusting sleeve interval and supports the supporting part of wind gap sleeve, rotation sleeve installs on the guiding axle, just rotation sleeve's one end with the protection shield is connected, screw thread sleeve installs the guiding axle is kept away from the one end of protection shield, the supporting part is installed rotation sleeve with screw thread sleeve is last. Optionally, the supporting part includes a plurality of first bracing pieces, a plurality of second bracing pieces, and a plurality of first bracing pieces are installed respectively rotate telescopic top and bottom, a plurality of second bracing pieces are installed respectively threaded sleeve's top and bottom, a plurality of first bracing pieces with a plurality of second bracing pieces one-to-one, just the one end of first bracing piece is connected with the one end of second bracing piece.
