DETAILED DESCRIPTION

[0034] In order to make the purpose, technical scheme and advantages of the utility model more clear and intelligible, the utility model will be further described in detail below in combination with embodiments, but the scope of protection required by the utility model is not limited to the following specific embodiments.

[0035] REFERENCE Figure 1 and Figure 2 A novel multifunctional crown casing shock-absorbing box, comprising a first bolt 11, a support sleeve 12, a flexible buffer block 21 and a second bolt 41, the first bolt 11 is fixedly installed with a support plate 13, the support plate 13 is fixedly connected with one end of the support sleeve 12, the support sleeve 12 is provided with a buffer groove 14, the buffer groove 14 is open towards the direction away from the first bolt 11, the flexible buffer block 21 is clamped into the buffer groove 14, the second bolt 41 is provided with a connecting plate 42, one end of the flexible buffer block 21 away from the first bolt 11 is provided with a connecting groove 43, the connecting groove 43 is matched with the connecting plate 42, the flexible buffer block 21 is internally provided with a buffer cavity 31, and the second bolt 41 is fixedly connected with a conical body 32 clamped into the buffer cavity 31. The first bolt 11 and the second bolt 41 are connected with the upper frame and the lower frame of the shell breaker respectively, so as to conveniently install the shock-absorbing box between the upper frame and the lower frame. When the second bolt 41 vibrates relative to the first bolt 11, the second bolt 41 drives the conical body 32 to vibrate in the support sleeve 12. The flexible buffer block 21 is integrally injection molded on the conical body 32 in polyurethane material, which is convenient for processing, and the flexible buffer block 21 and the conical body 32 are closely and reliably attached.

[0036] The support sleeve 12 is in a whole cylindrical shape, so that the support sleeve 12 can wrap the outer circumferential surface of the flexible buffer block 21, and the support sleeve 12 can stably support the flexible buffer block 21 in the radial direction, thereby improving the stability of the flexible buffer block 21. The support sleeve 12 is provided with an exhaust hole 15 communicating with the buffer groove 14 at one end close to the support plate 13. During the elastic deformation of the flexible buffer block 21 in the support sleeve 12, the air in the support sleeve 12 is discharged through the exhaust hole 15, thereby reducing the air flowing between the support sleeve 12 and the flexible buffer block 21, and the support sleeve 12 can stably support the flexible buffer block 21.

[0037] The flexible buffer block 21 is provided with a support plane 25 abutting against the support plate 13. When subjected to an axial impact, the support plate 13 can stably support the flexible buffer block 21 through the abutment of the support plane 25 and the support plate 13, thereby improving the stability of the flexible buffer block 21. The flexible buffer block 21 is provided with an arc surface 26 on the outer side, and the arc surface 26 is clamped with the inner wall of the support sleeve 12. The flexible buffer block 21 is abutted with the support sleeve 12 through the arc surface 26, and the flexible buffer block 21 can be pressed into the support sleeve 12 along the arc surface 26, thereby guiding the flexible buffer block 21 into the support sleeve 12 through the arc surface 26, and facilitating the assembly. Meanwhile, the arc surface 26 can be deformed when subjected to a radial impact, so that the flexible buffer block 21 and the support sleeve 12 have a certain elastic deformation space, and the flexible buffer block 21 can absorb the impact during the elastic deformation, thereby ensuring the impact absorption effect of the flexible buffer block 21.

[0038] The flexible buffer block 21 is provided with a clamping ring 22 located between the connecting groove 43 and the buffer cavity 31, and the clamping ring 22 is provided with a clamping surface 23 clamped with the connecting plate 42. The clamping surface 23 is abutted with the connecting plate 42, so that the connecting plate 42 can press the clamping ring 22, and the flexible buffer block 21 can be stably sleeved on the conical body 32, thereby preventing the flexible buffer block 21 from falling off the conical body 32. The clamping ring 22 is provided with an inclined surface 24 clamped with the conical body 32. The inclined surface 24 is abutted with the conical body 32, so that the conical body 32 and the connecting plate 42 can clamp the clamping ring 22, thereby preventing the flexible buffer block 21 from falling off the conical body 32. Moreover, when subjected to a radial impact, the inclined surface 24 abutted with the conical body 32 can make the flexible buffer block 21 more effectively absorb the impact force, thereby improving the impact absorption effect.

[0039] The conical body 32 is provided with a conical surface 33, a circular arc surface 34 and a supporting surface 35. The conical surface 33 is attached to the inclined surface 24. The width of the conical body 32 at the inclined surface 24 gradually increases in the direction close to the supporting plate 13. The circular arc surface 34 is located between the conical surface 33 and the supporting surface 35. The two ends of the circular arc surface 34 are smoothly connected to the conical surface 33 and the supporting surface 35, respectively. The supporting surface 35 is located at one end of the conical body 32 close to the supporting plate 13, and is parallel to the supporting plate 13. When subjected to a radial impact, the flexible buffer block 21 is extruded by the circular arc surface 34, so that the flexible buffer block 21 is deformed in the axial direction to the two sides, thereby absorbing the impact through the deformation and collapse of the flexible buffer block 21, and improving the effect of absorbing the impact of the flexible buffer block 21.

[0040] The second bolt 41 is provided with a pressing sleeve 44. The pressing sleeve 44 is sleeved on the second bolt 41 and is clamped to one end of the connecting plate 42 away from the flexible buffer block 21. The pressing sleeve 44 presses the connecting plate 42 to provide pressure to the connecting plate 42, so that the connecting plate 42 can press the flexible buffer block 21 tightly to improve the stability of the flexible buffer block 21. The pressing sleeve 44 is provided with a step 45 clamped to the connecting plate 42. The second bolt 41 is sleeved with a pressing plate 46 for clamping the lower frame of the shell breaking machine to improve the structural stability between the second bolt 41 and the lower frame of the shell breaking machine. The pressing plate 46 is clamped to one end of the pressing sleeve 44 away from the connecting plate 42. The side of the pressing plate 46 close to the pressing sleeve 44 is fixedly connected with a positioning sleeve 47 sleeved on the outer circumferential surface of the pressing sleeve 44. One end of the positioning sleeve 47 away from the pressing plate 46 is clamped to the step 45. The second bolt 41 is threadedly connected with a nut 48. The step 45 is pressed on the connecting plate 42 to increase the stress area of the connecting plate 42, so that the pressing sleeve 44 can press the connecting plate 42 tightly. The pressing plate 46 and the positioning sleeve 47 apply pressure on the step 45 and the pressing sleeve 44, so that the pressing sleeve 44 can press the connecting plate 42 tightly. The positioning sleeve 47 is attached to the outer circumferential surface of the pressing sleeve 44 to improve the structural stability between the pressing sleeve 44 and the pressing plate 46.

[0041] The embodiment has the following advantages:

[0042] When the shell breaking machine is working, high-frequency vibration occurs between the upper frame and the lower frame. When subjected to an axial impact of the first bolt 11, the conical body 32 extrudes the flexible buffer block 21 in the direction close to the first bolt 11, absorbs the axial impact through the flexible buffer block 21, reduces the impact force transmitted between the upper frame and the lower frame, and improves the structural reliability. However, when subjected to a radial impact perpendicular to the first bolt 11, the conical body 32 extrudes the flexible buffer block 21 towards the inner wall of the supporting sleeve 12, absorbs the radial impact through the flexible buffer block 21, reduces the impact force transmitted between the upper frame and the lower frame, and improves the structural reliability.

[0043] The new multifunctional crown shearer shell beating shock absorbing box absorbs tangential and radial impact between the upper frame and the lower frame, can effectively improve the structural stability between the upper frame and the lower frame, can reduce the load borne by the bolts between the upper frame and the lower frame, can prevent the bolts from loosening and dislocating in high-frequency vibration by absorbing radial impact, prolongs the service life of the mechanism and reduces the failure rate, enables the electrolysis workshop to continuously and normally operate, and has the advantages that the structural reliability between the upper frame and the lower frame of the shell beating machine is good.

[0044] The second bolt 41 is clamped into the flexible buffer block 21 through the conical body 32, and the flexible buffer block 21 is clamped by the connecting plate 42, so that the flexible buffer block 21 can be stably sleeved on the conical body 32, and the connecting structure between the connecting plate 42 and the flexible buffer block 21 is kept reliable through the cooperation of the connecting groove 43 and the connecting plate 42, thereby improving the structural stability between the flexible buffer block 21 and the conical body 32.
