[0002] At present, the brake system suitable for anchor winches mainly consists of brake rings and brake pads, and the brake ring is generally composed of ear plates and brake hoops.

Although this patent can prevent the radial deformation of the cylinder segment when the two sections of the cylinder segment are axially spliced ​​and welded, thereby ensuring the roundness of the cylinder and the quality of the product, it still has the following defects: This design cannot avoid excessive position deviation between the brake hoop and the ear plate during assembly and welding, which results in large deformation of the inner circle size of the brake ring.

[0068] When in use, first install the adjusting top block 2 in the dovetail slot 121. The width of the adjusting top block 2 is larger than the small side dimension of the dovetail slot 121 and smaller than the large side dimension of the dovetail slot 121, which can ensure that the adjusting top block 2 can slide smoothly in the dovetail slot 121 without falling out of the dovetail slot 121; then pass the push block 3 through the waist-shaped hole 122 and contact the corresponding two adjusting top blocks 2, and then pass the tightening bolt 6 through the connecting threaded hole 111 on the center tube 11 and screw it into the tightening threaded hole 31 on the push block 3. By adjusting the tightening bolt 6, the push block 3 is pushed to move, so that the push block 3 pushes the corresponding two adjusting top blocks 2 to move, thereby making the adjusting top block 2 contact the inner ring of the brake ring 7 and make the brake ring 7 round.

[0069] Embodiment 4: The basic content is the same as that of Example 1, except that the method of use comprises the following steps: Step 1: First draw the cross center line and outer contour line of the brake ring 7 on the assembly platform, then align the ear plates 71 and brake hoops 72 of the two brake rings 7 and place them on the assembly platform, and finally add a wedge block 73 between the two brake rings 7; Step 2: first install the adjusting top block 2 in the dovetail groove 121 of the support plate 1, then place the support plate 1 in the brake ring 7, and make the cross center of the support plate 1 coincide with the cross center line of the brake ring 7; Step 3: first place the four push blocks 3 in the four waist-shaped holes 122 of the support plate 1, and then pass the tightening bolts 6 through the connecting threaded holes 111 on the central tube 11 and screw them into the tightening threaded holes 31 on the push blocks 3; Step 4: First, insert the connecting pin 5 into the center holes 711 of the two adjacent ear plates 71 respectively, then sequentially pass the locking link 4 through the connecting holes 51 of the two connecting pins 5, then fix the nut 41 installed at one end of the locking link 4, and rotate the sleeve 42 installed at the other end of the locking link 4 to adjust the position between the two ear plates 71 until the relative position of the two adjacent ear plates 71 meets the size requirements of the drawing, and then stop rotating the sleeve 42; Step 5: First, adjust the tightening bolts 6 symmetrically and evenly. The tightening bolts 6 push the push block 3 to adjust the position of the adjusting top block 2 until the adjusting top block 2 contacts the inner ring of the brake ring 7 and rounds the brake ring 7. Then check against the contour line on the assembly platform until the outer contour of the brake ring 7 coincides with the contour line on the assembly platform, and the deviation is ≤1mm; Step 6: After the assembly is completed, the welding process is started to weld the ear plate 71 to the corresponding brake hoop 72.

[0070] Embodiment 5: The basic content is the same as Example 1, except that: in the first step, first drawing the cross center line and outer contour line of the brake ring 7 on the assembly platform means: first drawing the cross center line of the two assembled brake rings 7 and the outer contour lines of the brake hoop 72 and the ear plate 71 on the assembly platform according to the assembly drawing; in the first step, then placing the ear plate 71 and the brake hoop 72 of the two brake rings 7 on the assembly platform in line means: placing the brake hoop 72 and the ear plate 71 on the assembly platform respectively according to the contour lines; in the first step, finally adding a wedge block 73 in the middle of the two brake rings 7 means: placing two wedge blocks 73 in the middle of the two brake hoops 72, and respectively contacting the end faces of the brake hoop 72, so that the brake hoop 72 and the wedge block 73 form a complete circle.

[0071] When in use, since the brake hoops 72 of the two brake rings 7 cannot form a complete circle, a wedge block 73 of appropriate size is selected according to the brake rings 7 of different sizes, and the wedge block 73 is placed in the middle of the brake ring 7 and in contact with the two end surfaces of the brake hoop 72, so that the two brake rings 7 and the wedge block 73 form a complete circle. In addition, due to the presence of the wedge block 73, when fixing the locking link 4, the locking link 4 is prevented from being screwed over the size and causing the inner circle of the brake ring 7 to be deformed, so that the inner circle size of the brake ring 7 is more in line with the requirements of the drawing.

[0072] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed by the present invention should be included in the protection scope recorded in the claims.
