Embodiment 1

[0023] Embodiment 1: as attached figure 1 As shown, the rod grinding mechanism includes at least two sections of sleeves, rotating shafts, high-speed self-aligning bearings, flexible positioning sleeves, high-speed support bearings and support cylinders 8, adjacent sleeves are fixedly installed together, and at least Two sections of rotating shafts are fixedly connected together in sequence. Grinding wheel 1 is fixedly installed on the rotating shaft outside the leftmost sleeve. The inner rings of at least four high-speed self-aligning bearings are fixed together with the rotating shaft. At least four high-speed self-aligning bearings The outer ring of the sleeve is fixed together with the sleeve. The right end of the rightmost sleeve is fixedly equipped with a support tube 8. The right end of the rotating shaft passes through the support tube 8 and is located outside the support tube 8. Inside the two ends of the support tube 8, there are respectively A high-speed self-aligni...

Embodiment 2

[0030] Embodiment 2: as attached figure 2 , 3 As shown, a pipe wall high-speed internal grinding device includes a grinding rod mechanism, a frame 9, a trolley 23, a hinged support 24 and a pressurized cylinder 25, and the frame 9 is equipped with a horizontal movement along the frame 9. Dolly 23, on dolly 23 is fixedly installed with articulated support 24, and sleeve is hingedly installed on articulated support 24 and can rotate left and right along articulated support 24, is fixed with counterweight 27 on the left end top of sleeve, on dolly 23 is fixed with the pressurized cylinder 25 that is positioned at the sleeve below and corresponds to the counterweight 27, and the power transmission device 28 that can drive the rotating shaft to rotate is fixedly installed on the sleeve.

Abstract

The invention relates to the technical field of grinding of inner pipe walls, in particular to a grinding rod mechanism and a high-speed pipe wall internal grinding device. The grinding rod mechanism comprises at least two sections of sleeves, rotary shafts, high-speed self-aligning bearings, flexible positioning sleeves, high-speed supporting bearings and a supporting cylinder. Every two adjacent sleeves are fixedly installed together. The grinding rod mechanism and the high-speed pipe wall internal grinding device are reasonable in structure and convenient to use, and by arranging the high-speed self-aligning bearings in different positions of the rotary shafts, the rotation speed of the rotary shafts can be effectively improved; and by arranging the flexible positioning sleeves, rigid vibration can be relieved, the sleeves and the high-speed self-aligning bearings are protected, the service life of the bearings is prolonged, and the rotation speed is improved by 2-3 times compared with the grinding rotation speed of existing inner wall grinding equipment. Through cooperation of a balancing weight and a pressurization air cylinder, a grinding rod is located in a fixed position to work, the pressurization air cylinder can adjust the pressure conveniently, the rotary shafts can reach the specific positions and be positioned rapidly and conveniently, and accordingly the grinding effect is improved. By arranging a lead screw elevator to support the sleeves, the situation of dipping and heaving is relieved, and the grinding quality is improved.

Description

technical field [0001] The invention relates to the technical field of pipe inner wall grinding, and relates to a rod grinding mechanism and a high-speed internal pipe wall grinding device. Background technique [0002] The inner wall of cast iron pipe after cement lining is easy to form impurities with uneven thickness, high points, and cement residues. The inner wall needs to be smooth and evenly ground. However, the existing inner wall grinding equipment has poor grinding effect due to low speed. And because the rotating shaft is longer in the grinding process, the weights at both ends are inconsistent, so that the grinding wheel on the rotating shaft enters the inner wall of the cast iron pipe because the rotating shaft is easy to float up and down, and the balance stability is poor, so a good grinding effect cannot be achieved. Without good grinding equipment, most manufacturers can only rely on manpower to grind with hand grinding wheels at the mouth of the pipe wall o...
