Description
Technical Field
[0001] This utility model belongs to the technical field of mechanical parts for mining equipment and can be applied to strong magnetic separators. Specifically, it is a non-loosening through bolt installation structure for strong magnetic separators. Background Technology
[0002] The main equipment used in a mineral processing plant for powder ore processing includes the ZH-3200 high-intensity magnetic separator and the SLon-2500 high-gradient vertical ring magnetic separator. The ZH-3200 high-intensity magnetic separator mainly consists of a drive motor, a rotary reducer, upper / lower rotary tables, and a concentrate / tailings receiving tray. The entire machine weighs approximately 160 tons and has advantages such as good separation effect, simple structure, and easy operation. However, it also has disadvantages such as loosening of T-bolts and anti-loosening through bolts, and easy wear of the toothed plates and spacers. In addition, the anti-loosening through bolts of the ZH-3200 high-intensity magnetic separator are located in special positions and are difficult to inspect during operation. If the anti-loosening through bolts are not tightened in time, problems such as breakage of the anti-loosening through bolts, loosening of the toothed plates, and wear of the spacers may occur. These problems often require shutdown for inspection and maintenance, which not only leads to low operating rate of the high-intensity magnetic separator, but also results in high labor intensity for manually tightening the anti-loosening through bolts and T-bolts. Utility Model Content
[0003] The purpose of this utility model is to address the problems existing in the prior art by providing an anti-loosening through bolt installation structure for a strong magnetic separator, which solves the problems of easy loosening of T-bolts and anti-loosening through bolts that tightly connect the tooth plate, partition block and turntable in a strong magnetic separator used in a mineral processing plant, as well as easy wear of the tooth plate and partition block.
[0004] Therefore, the present invention adopts the following technical solution: An anti-loosening through-bolt mounting structure for a high-intensity magnetic separator includes an anti-loosening through-bolt that is threadedly connected to the turntable of the high-intensity magnetic separator. The turntable includes several toothed plates, and symmetrically arranged partitions are provided on both sides of the toothed plates. Several anti-loosening through-bolts are installed in the gaps between adjacent partitions and connected to the turntable by anti-loosening through-bolt nuts.
[0005] Furthermore, the top of the partition is provided with a mounting groove, and a T-bolt is provided inside the mounting groove. The nut end of the T-bolt is located at the bottom of the mounting groove, and the screw end extends outward to the outside of the partition.
[0006] Furthermore, the top of the toothed plate is provided with a pressure cap, and the pressure cap is provided with a bolt hole at the position corresponding to the T-bolt, and it is threadedly connected to the tail end of the T-bolt.
[0007] Furthermore, the length of the pressure cap is greater than that of the toothed plate, and both ends of the cap extend beyond the edge of the toothed plate.
[0008] Furthermore, the anti-loosening through bolt includes a threaded portion and a rectangular portion. Both ends of the threaded portion are threaded, and the rectangular portion and the threaded portion are manufactured as a single piece. The rectangular portion of the anti-loosening through bolt is precisely fitted into the gap formed at the end of the adjacent pressure cap.
[0009] Furthermore, the rectangular portion has a length of 15mm and a width of 10mm.
[0010] This utility model has the following advantages compared with the prior art: This invention utilizes a strong magnet cover to effectively prevent the anti-loosening through bolt from rotating due to factors such as magnetic fields and equipment rotation. The rectangular portion of the anti-loosening through bolt, used in conjunction with the strong magnet cover, effectively secures the bolt and prevents it from loosening. A special wrench can be used to tighten and maintain the rectangular portion of the anti-loosening through bolt, reducing downtime for the strong magnet and improving equipment operating efficiency.

[0013] The technical solution of this utility model will be described below with reference to the accompanying drawings and implementation methods.
[0014] like Figure 1 and 2 As shown, an anti-loosening through bolt mounting structure for a strong magnetic separator includes an anti-loosening through bolt 1, which is threadedly connected to the turntable 2 of the strong magnetic separator.
[0015] like Figure 3 As shown, the turntable 2 includes several toothed plates 3, and the toothed plates 3 are provided with symmetrically arranged partitions 4 on both sides. Two anti-loosening through bolts 1 are installed side by side in the gap between adjacent partitions 4 and are connected to the turntable 2 through anti-loosening through bolt nuts 5. The top of the toothed plate 3 is provided with a pressure cap 7, and the pressure cap 7 is provided with bolt holes at the positions corresponding to the T-bolts 6, and is threaded to the tail end of the T-bolts 6. The length of the pressure cap 7 is greater than that of the toothed plate 3, and both ends of it extend beyond the edge of the toothed plate 3.
[0016] The top of the spacer block 4 is provided with a mounting groove, a T-shaped bolt 6 is arranged in the mounting groove, the nut end of the T-shaped bolt 6 is located at the bottom of the mounting groove, and the screw rod end extends outward to the outside of the spacer block 4.
[0017] As Figure 4 shown, the anti-loosening through bolt 1 comprises a screw rod portion and a rectangular portion, the screw rod portion comprises a cylindrical portion and a threaded portion, the material of the rectangular portion of the anti-loosening through bolt is consistent with that of the rod portion of the anti-loosening through bolt, and the anti-loosening through bolt needs to be integrally processed, the overall length is 250mm, wherein the length of the rectangular portion is 15mm, the width is 10mm, the length of the cylindrical portion is 240mm, and the diameter is 32mm; the rectangular portion of the anti-loosening through bolt 1 is exactly clamped in the gap formed between the two ends of adjacent press covers 7.
[0018] After the present utility model is installed, the rectangular portion of the anti-loosening through bolt 1 is located in the gap formed between two adjacent press covers 7, and the rectangular portion is arranged vertically after installation, thereby achieving the effect of preventing the anti-loosening through bolt from loosening.
[0019] When the present utility model is in use, the tightening of the anti-loosening through bolt 1 must use a special wrench, and the connection between the anti-loosening through bolt and the rotary table must be confirmed to be tightened; after the nut of the anti-loosening through bolt 1 is tightened, a special wrench is used to adjust the position of the rectangular part at the front end of the anti-loosening through bolt 1, so that the rectangle maintains a "day" shape, that is, the rectangular part is arranged vertically between two adjacent press covers 7; after the tooth plate 3 and the press cover 7 are installed, it should be confirmed that the rectangular portion of the anti-loosening through bolt 1 does not exceed the outer edge of the press cover 7; if there is any excess part, check whether the anti-loosening through bolt 1 is fastened in place at the position of the rotary table 2, and check the thickness of the press cover 7. If the thickness is less than the specified value, the press cover 7 shall be replaced.
