[0005] In order to solve the above-mentioned technical problems, the present invention provides a steel pipe rod with an inner wall support frame, including a retaining frame and a bearing; the retaining frame includes a front retaining frame and a rear retaining frame, and the front retaining frame and the rear retaining frame are connected in pairs through support rods, and a plurality of groups of first load-bearing support blocks are evenly fixed on the inner walls of the front retaining frame and the rear retaining frame, an inner frame is fixedly welded at the bottom recess of the first load-bearing support block, and the inner frame wall of the inner frame is fixedly connected to the second load-bearing support block by bolts, and the bottom end face of the second load-bearing support block is attached to the outer outer ring of the bearing, the threaded inner ring on the bearing is threaded with the top rod, and the bottom base of the top rod is fixedly connected to the flange.

[0006] Furthermore, 8 groups of screw holes are evenly arranged on the outer wall of the base to which the bottom of the top rod is fixed, and the insertion rods inserted in the screw holes pass through the convex layer and are fixed on the flange, and a buckle is fixedly installed at the end of the insertion rod.

[0007] Furthermore, the outer ring surfaces of the front section retainer and the rear section retainer are beveled.

[0008] Furthermore, the inner frame is octagonal.

[0009] After adopting the above structure, compared with the prior art, the present invention adopts a double retainer docking structure, which solves the technical problem of local extrusion deformation caused by excessive contact area and excessive weight of the steel pipe rod; the installation structure that is docked with the flange and retained inside the steel pipe rod solves the technical problem of deformation of the steel pipe rod due to external factors during subsequent use.

DETAILED DESCRIPTION

[0015] like Figure 1 , Figure 2 and Figure 3 As shown, a steel pipe rod with an inner wall support frame includes a retainer and a bearing; the retainer 1 includes a front retainer 1-1 and a rear retainer 1-2, the front retainer 1-1 and the rear retainer 1-2 are connected in pairs through a support rod 4, and a plurality of groups of first load-bearing support blocks 7 are evenly fixed on the inner walls of the front retainer 1-1 and the rear retainer 1-2, and an inner frame 9 is fixedly welded to the bottom recess of the first load-bearing support block 7, and the inner wall of the inner frame 9 is fixedly connected to the second load-bearing support block 8 by bolts 8-1, and the bottom end face of the second load-bearing support block 8 is attached to the outer outer ring 10 of the bearing 3, and the threaded inner ring 6 on the bearing 3 is threaded with the top rod 2, and the bottom base 5 of the top rod 2 is fixedly connected to the flange 11. Among them, since the radius of the steel pipe rod body decreases with the height, the front retainer 1-1 and the rear retainer 1-2 also match the size of the steel pipe rod body. In order to concentrate the pressure of the steel pipe rod body when the retainer is clamped in the steel pipe rod, the pressure is dispersed by the first load-bearing support block 7 installed on the inner wall of the retainer 1, and the pressure is concentrated on the inner frame 9, thus completing the first stage of the pressure dispersion process; and then the inner frame wall of the inner frame 9 is fixedly connected to the second load-bearing support block 8 by bolts 8-1 to complete the second stage of the pressure dispersion process. Finally, the bottom base 5 of the top rod 2 installed at the center end is fixedly connected to the flange 11 to complete the installation process of the retainer 1. The flange 11 is a connector for the longitudinal docking of the steel pipe rod, so the retainer 1 can be permanently retained in the steel pipe rod, which plays a role of secondary protection.

[0016] like Figure 2 and Figure 3As shown, 8 groups of screw holes 5-1 are evenly opened on the outer wall of the base 5 fixed at the bottom of the mandrel 2, and the insertion rod 13 inserted in the screw hole 5-1 passes through the convex layer 14 and is fixed on the flange 11, and a buckle 15 is fixedly installed at the end of the insertion rod 13. Among them, in order to fix the mandrel 2 on the center of the flange 11 and prevent the mandrel 2 from being offset due to errors or external forces during installation, the insertion rods 13 evenly distributed on the flange 11 are positioned and connected with the screw holes 5-1 of the base 5 at the bottom of the mandrel 2. The buckle 15 can wait for the insertion rod 13 to be installed and fix the position of the insertion rod 13 on the flange 11.

[0017] like Figure 2 As shown, the outer ring surfaces of the front section retainer 1-1 and the rear section retainer 1-2 are at an angle. The outer ring surfaces of the front section retainer 1-1 and the rear section retainer 1-2 are at an angle in order to increase the contact area with the inner wall of the steel pipe rod, thereby increasing the friction force and the applied pressure.

[0018] like Figure 1 As shown, the inner frame 9 is octagonal, wherein the octagonal end angles can better cooperate with the pressure transmitted by the dispersion retaining frame 1.
