Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-4 The utility model provides a technical solution: a sliding bearing assembly for a pump body, comprising a mounting frame 1, mounting bolts 2 are threadedly connected at the four corners of the upper surface of the mounting frame 1, a bearing seat 3 is overlapped on the upper surface of the mounting frame 1, mounting plates 4 are fixedly connected to the left and right sides of the bearing seat 3, locking bolts 5 are threadedly connected to the upper surfaces of the two mounting plates 4, a bearing cover 6 is overlapped on the upper surface of the bearing seat 3, bearing shells 7 are installed on the inner walls of the bearing seat 3 and the bearing cover 6, a fine-tuning component 8 is threadedly connected to the front of the mounting frame 1, and two auxiliary components 9 are fixedly connected to the upper surface of the bearing seat 3;

[0021] The fine-tuning assembly 8 includes a moving structure 81 and a limiting structure 82 . The limiting structure 82 is used to limit and fix the moving structure 81 .

[0022] Furthermore, the movable structure 81 includes a movable block 8101, a strip groove is provided on the upper surface of the mounting frame 1, the movable block 8101 is slidably connected to the inner bottom wall of the strip groove, and positioning plates 8102 are fixedly connected on both sides of the movable block 8101. The position of the positioning plate 8102 corresponds to the position of the mounting plate 4, and the upper surface of the positioning plate 8102 is provided with a threaded hole compatible with the locking bolt 5. A plurality of limiting holes 8103 are provided on the front of the movable block 8101, and a plurality of indicator blocks 8104 are fixedly connected to the front of the bearing seat 3 at a position corresponding to the axis of the limiting hole 8103. By using the mounting plate 4, the positioning plate 8102 and the locking bolt 5, the bearing seat 3 and the movable block 8101 can be quickly separated, thereby facilitating the replacement and maintenance of the bearing seat 3.

[0023] Furthermore, the limiting structure 82 includes an adjusting screw 8201, a cavity is opened inside the mounting frame 1, a strip block 8202 is slidably connected to the inner bottom wall of the cavity, a bearing sleeve 8203 is installed on the front of the strip block 8202, the rear end of the adjusting screw 8201 extends to the inside of the cavity and is fixedly connected to the inner wall of the bearing sleeve 8203, and a plurality of limiting plug rods 8204 are fixedly connected to the back of the strip block 8202. After the adjusting screw 8201 is rotated, it can move back and forth and drive the strip block 8202 to move back and forth at the same time. Due to the rotation effect of the bearing sleeve 8203, the strip block 8202 will not be affected by the rotation of the adjusting screw 8201.

[0024] Furthermore, the height of the limit rod 8204 is the same as the height of the limit hole 8103, the limit rod 8204 is adapted to the limit hole 8103, and the upper surface of the mounting frame 1 is provided with a plurality of indicator lines 8205 corresponding to the position of the limit rod 8204. The limit rod 8204 can be inserted into the limit hole 8103 to lock the movable block 8101, which can not only release the restriction and allow the movable block 8101 to move left and right to fine-tune the bearing seat 3, but also lock the movable block 8101 to ensure the stability of the bearing seat 3 after fine-tuning. The indicator lines 8205 and the indicator block 8104 can be used to align the limit rod 8204 with the limit hole 8103 to avoid the situation where the movable block 8101 cannot be limited due to insertion into the wrong position.

[0025] Furthermore, the auxiliary component 9 includes a positioning frame 901, the upper surface of the positioning frame 901 is provided with mounting screw holes, the upper surface of the positioning frame 901 is provided with two circular grooves, the inner wall of the circular groove is provided with two limit grooves, the inner bottom walls of the two limit grooves are respectively fixedly connected with a first limit rod 902 and a second limit rod 903, and the surfaces of the first limit rod 902 and the second limit rod 903 are both provided with springs 904.

[0026] Furthermore, the inner walls of the two limit grooves are slidably connected with a movable pressure plate 905, and the movable pressure plate 905 is slidably connected to the surfaces of the first limit rod 902 and the second limit rod 903 respectively, and the top end of the spring 904 overlaps with the lower surface of the movable pressure plate 905, and the bottom end overlaps with the inner bottom wall of the limit groove. The movable pressure plate 905 can slide up and down on the surfaces of the first limit rod 902 and the second limit rod 903, thereby driving the two springs 904 to produce a deformation effect.

[0027] Furthermore, the left and right sides of the bearing cover 6 are fixedly connected with a fixing plate 906, and the upper surface of the fixing plate 906 is threadedly connected with a fastening bolt 907, and the fastening bolt 907 is adapted to the mounting screw hole. The lower surface of the fixing plate 906 is fixedly connected with two push rods 908, and the positions of the two push rods 908 correspond to the positions of the two circular grooves respectively. The two push rods 908 can be inserted into the circular groove when the fastening bolt 907 on the fixing plate 906 is installed, and drive the movable pressure plate 905 to descend and squeeze the spring 904, so that the spring 904 always maintains the deformation effect. After the fastening bolt 907 is removed, the spring 904 loses its restriction and can drive the bearing cover 6 to pop out through the reaction force, without the need for manual pulling out by the staff, thereby improving the maintenance efficiency.

[0028] Working principle: First, use the mounting bolts 2 and the mounting bracket 1 to fix it on the pump body. When it is necessary to fine-tune the bearing seat 3, rotate the adjusting screw 8201 so that the bar block 8202 drives the limit plug 8204 to first disengage from the two limit holes 8103 on the front of the movable block 8101. At this time, the movable block 8101 loses its restriction and can move the bearing seat 3 to drive the movable block 8101 to move left and right, thereby fine-tuning the position of the bearing seat 3. Use the indicator block 8104 and the indicator line 8205 to align the limit hole 8103 with the limit plug 8204. After fine-tuning, rotate the adjusting screw 8201 in the opposite direction so that it drives the bar block 8202 to move backward through the bearing sleeve 8203, thereby driving the limit plug 8204 to insert into the limit hole 8 103 locks the movable block 8101, thereby locking the position of the bearing seat 3, and can achieve fine-tuning operation on the bearing seat 3, with high flexibility and relatively simple operation. The bearing seat 3 can be quickly separated from the movable block 8101 by using the mounting plate 4, the positioning plate 8102 and the locking bolt 5. When the bearing cover 6 needs to be inspected and replaced, the spring 904 can be unscrewed by screwing out the fastening bolt 907, thereby generating a reaction force, driving the movable pressure plate 905 to rise, thereby driving the fixed plate 906 and the bearing cover 6 to separate from the surface of the bearing seat 3 through the push rod 908, so that the bearing cover 6 can be automatically popped out, effectively solving the problem that the bearing cover 6 is difficult to pull out due to the tight fit between the bearing cover 6 and the bearing seat 3, and is more practical.
