[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a gyratory crusher cross beam, including a central body 1, the left and right sides of the central body 1 are fixedly connected with beam walls 3, the inner side of the beam wall 3 is fixedly connected with a fixed block 4, the outer side of the fixed block 4 is fixedly connected with a spring telescopic rod 5, the telescopic end of the spring telescopic rod 5 is fixedly connected with a U-shaped block 6, the inner top of the U-shaped block 6 is rotatably connected with a second rotating plate 25, the outer side of the spring telescopic rod 5 is rotatably connected with a first rotating plate 7, the top of the first rotating plate 7 is rotatably connected with a lifting plate 8, the inner side of the lifting plate 8 is rotatably connected with the second rotating plate 25, the top middle part of the lifting plate 8 is fixedly connected with a slot plate 9, the inner wall of the slot plate 9 is rotatably connected with a rotating rod 10, the adjacent two rotating rods 10 are fixedly connected with a spring 11, the outer sides of the plurality of rotating rods 10 are rotatably connected with a U-shaped plate 12, and the outer side of the central body 1 is provided with a mounting mechanism 2;

[0030] Specifically, the extension and retraction of the spring telescopic rod 5 can move the U-shaped block 6, and thereby drive the second rotating plate 25 to rotate, and then cause the lifting plate 8 to move up and down through the operation of the second rotating plate 25. At the same time, the extension and retraction of the spring 11 causes the rotating rod 10 to rotate along the inner side of the groove plate 9. The elastic potential energy can be used to buffer the external impact at different positions. Compared with relying solely on the structure to withstand the impact, the impact force can be dispersed, reducing the risk of breakage and deformation.

[0031] Reference Figure 1 and Figure 3 The mounting mechanism 2 includes a connecting plate 201, which is fixedly connected to the outer side of the beam wall 3, and a gear 204 is rotatably connected to the inner side of the connecting plate 201. A reserved groove 202 is provided on the front and rear sides of the connecting plate 201, and a rack 203 is slidably connected to the inner side of the reserved groove 202. The upper and lower sides of the gear 204 are respectively meshed with the corresponding rack 203. A mounting plate 205 is provided on the left side of the connecting plate 201, and a rotating column 206 is rotatably connected to the inner top of the mounting plate 205. A first bevel gear 207 is fixedly connected to the outer side of the rotating column 206, and a T-block 208 is fixedly connected to the inner side of the mounting plate 205. A second bevel gear 209 is rotatably connected to the outer side of the T-block 208. The second bevel gear 209 is meshed with the first bevel gear 207. The front and rear sides of the inner wall of the mounting plate 205 are provided with plug-in grooves 210, and the rack 203 is engaged with the plug-in groove 210.

[0032] Specifically, the connecting plate 201 is placed inside the mounting plate 205, and then the rotating column 206 is rotated to start the rotation of the first bevel gear 207. Subsequently, through meshing transmission, the second bevel gear 209 is driven to rotate. Since the connecting plate 201 is aligned with the mounting plate 205, the second bevel gear 209 will be aligned with and engaged with the gear 204. Therefore, when the second bevel gear 209 rotates, the gear 204 will also rotate. Subsequently, through meshing transmission, the rack 203 will extend along the reserved groove 202, and connect and engage with the plug-in groove 210 on the inner side of the mounting plate 205, thereby fixing the position of the connecting plate 201 and the mounting plate 205.

[0033] Reference Figure 1 and Figure 3 , the front and rear sides of the outer wall of the connecting plate 201 are fixedly connected with hollow blocks 19, the inner side of the hollow block 19 is slidably connected with a sliding rod 20, and the sliding rod 20 is engaged with the rack 203; the top of the mounting plate 205 is rotatably connected with a handle 22, the bottom of the handle 22 passes through the mounting plate 205 and is fixedly connected to the rotating column 206; the outer side of the mounting plate 205 is fixedly connected with a bracket 23, the top of the bracket 23 is fixedly connected with a support plate 24, and the outer side of the second bevel gear 209 is fixedly connected with a mounting block 21;

[0034] Specifically, by extending the sliding rod 20 from the hollow block 19, it can be engaged with the rack 203 to prevent the rack 203 from being displaced due to vibration or external impact, which would cause the device to be loosely fixed. The handle 22 can facilitate the operation of the rotating column 206 for rotation, and the bracket 23 and the mounting block 21 thereon can improve the stability and supporting capacity of the mounting plate 205 fixing the connecting plate 201.

[0035] Reference Figure 1 and Figure 2 The bottom of the beam wall 3 is fixedly connected with a bottom plate 15, and a plurality of air holes 16 are provided on the outer side of the bottom plate 15; the outer side of the U-shaped plate 12 is fixedly connected with a connecting rod 13, and the outer side of the connecting rod 13 passes through the beam wall 3 and is fixedly connected with a baffle 14; the top of the central body 1 is fixedly connected with a motor 17, and the output end of the motor 17 is fixedly connected with a top cover 18;

[0036] Specifically, ventilation can be carried out through the bottom plate 15 and the air holes 16 thereon to prevent the inside of the beam wall 3 from getting damp. Through the connecting rod 13 and the baffle plate 14, an additional baffle plate 14 can be added on the outside of the beam wall 3 to enhance the protection capability of the beam wall 3 against impact. By driving the top cover 18 to rotate by the motor 17, gravel can be thrown away to prevent stones from accumulating on the top of the device. At the same time, the rotating top cover 18 can also reduce the impact force of the stones directly impacting the top of the device.

[0037] Working principle: Before using the device, first, the extension and retraction of the spring telescopic rod 5 pushes the U-shaped block 6 to move. Subsequently, the movement of the U-shaped block 6 causes the second rotating plate 25 to rotate, and the operation of the second rotating plate 25 drives the lifting plate 8 to move up and down. On the other hand, through the extension and retraction of the spring 11, the rotating rod 10 rotates along the inner side of the slot plate 9. This design uses elastic potential energy to buffer external impacts. Compared with simply relying on the structure to withstand impact force, it reduces the risk of breakage and deformation, thereby improving the reliability of the device. After the connecting plate 201 is inserted into the mounting plate 205, the rotating column 206 can rotate the first bevel gear 207, and the meshing The second bevel gear 209 will also be driven to rotate. At the same time, since the connecting plate 201 is opposite to the mounting plate 205, the second bevel gear 209 will be aligned with and engaged with the gear 204. Therefore, when the second bevel gear 209 rotates, it will also drive the gear 204 to rotate together. Then, through the meshing transmission, the rack 203 will extend from the reserved groove 202, and connect and engage with the plug-in groove 210 on the inner side of the mounting plate 205 to fix the position between the connecting plate 201 and the mounting plate 205. This design realizes a quick disassembly and assembly device without the need for operation from the inside, simplifies the installation process, and thus improves the practicability of the device.
