[0030] The following is combined with Figure 1-6 This application is described in further detail.
[0031] See also Figure 1-3 A cleaning-free device for the pouring mouth of a circular steel column core pouring comprises a steel column 1 and a protective mechanism 2 installed on the steel column 1. The outer wall of the steel column 1 is provided with a pouring mouth for installing the protective mechanism 2. The protective mechanism 2 comprises a protective sleeve 3, and the protective sleeve 3 is inserted into the inner wall of the pouring mouth. The inner wall of the protective sleeve 3 is provided with three equidistantly distributed tensioning components 4. The outer wall of the protective sleeve 3 is fixedly connected with a mounting ring 5, and two symmetrically arranged clamping components 6 are installed on the outer wall of one side of the mounting ring 5.
[0032] When in use, the setting of the protective mechanism 2 is convenient for protecting the pouring mouth on the steel column 1 to prevent the pouring mouth from being contaminated when the steel column 1 is poured. The tensioning component 4 and the pressing component 6 are arranged in the protective sleeve 3 to cooperate with each other, which makes it convenient to fix the protective sleeve 3 on the pouring mouth.
[0033] Reference Figure 3-4 The tensioning assembly 4 includes an arc-shaped seat 7, and a circular opening is opened on the outer wall of the top of the arc-shaped seat 7. The inner wall of the circular opening is rotatably connected to a threaded tube 8. The setting of the arc-shaped seat 7 makes it convenient to install the tensioning assembly 4 on the inner wall of the protective sleeve 3, and the setting of the circular opening facilitates the rotatable installation of the threaded tube 8.
[0034] Reference Figure 3-4 The inner wall of the threaded tube 8 is threaded with a screw 12, and one end of the screw 12 is fixedly connected to a rotating head 9. The rotating head 9 is directly driven to be pressed against the inner wall of the steel column 1 by rotating the screw 12 in the threaded tube 8. The rotatable rotating head 9 is arranged to facilitate the installation of the protective cover 3.
[0035] Reference Figure 4 The other end of the screw 12 is rotatably connected to the connecting seat 10, and the top outer wall of the connecting seat 10 is fixedly connected to a rubber pad 11. The rubber pad 11 on the connecting seat 10 can conveniently reduce the wear between the connecting seat 10 and the inner wall of the steel column 1.
[0036] Reference Figure 2 The inner wall of the protective sleeve 3 is provided with three equally spaced arc grooves, and the arc seat 7 is fixedly connected to the inner wall of the arc groove. The arrangement of the arc groove makes it convenient to install the arc seat 7.
[0037] Reference Figure 5-6 The clamping assembly 6 includes a clamping seat 13 fixedly connected to the mounting ring 5, and a circular opening is provided on the outer wall of the bottom of the clamping seat 13. The arrangement of the clamping seat 13 facilitates the installation of the clamping assembly 6 on the mounting ring 5.

When the sliding seat 15 moves, it is convenient to directly drive the pressing column 14 to press on the outer wall of the steel column 1.
[0040] The implementation principle of this application is: during use, when the steel column 1 needs to be cast, the protective mechanism 2 is first installed on the casting mouth. During installation, the protective sleeve 3 is first inserted into the casting mouth, and then the threaded tube 8 is rotated to rotate the connecting seat 10 out of contact with the inner wall of the steel column 1, and then the rotating head 9 is rotated to drive the screw 12 to rotate, thereby facilitating the driving of the rubber pad 11 on the connecting seat 10 to be pressed against the inner wall of the steel column 1. At the same time, the clamping column 14 on the clamping assembly 6 is pressed against the outer wall of the steel column 1 by the drive of the spring 17, thereby ensuring the stability of the protective sleeve 3.
