Description

Technical Field

[0001] The invention belongs to the technical field of buffering and shock absorption of cone crushers, and in particular relates to a device for reducing vibration of cone crushers. Background Art

[0002] Cone crusher is a kind of equipment suitable for raw material crushing in metallurgy, construction, road construction, chemical and silicate industries. Cone crusher has large crushing ratio, high efficiency, low energy consumption, uniform product size, and is suitable for medium and fine crushing of various ores and rocks.

[0003] At present, the mainframe and base of cone crushers in the industry are mostly rigidly connected. The vibration load generated by the equipment during vibration operation is directly transmitted to the concrete foundation or steel structure foundation through the base. Long-term use can easily cause cracking and settlement of the concrete foundation, cracking and breaking of the welds of the steel structure foundation, etc., and even cause safety accidents in serious cases. In order to delay the occurrence of the above situation, the concrete foundation and steel structure foundation are enlarged and thickened, but this design increases the equipment installation and manufacturing costs, and the essence of the problem has not been effectively solved.

[0004] The Chinese utility model patent entitled "Shock-absorbing base for cone crusher" (patent number CN96226467.9) discloses a shock-absorbing base, which is composed of a buffer layer corresponding to the shape of the crusher base and a base cushion layer larger than the outer edge of the buffer layer plane. The base cushion layer is provided with regularly distributed positioning holes. The base cushion layer is connected to the concrete foundation by bolts. The shock-absorbing base is used to achieve shock absorption of the cone crusher. However, the service life of this shock-absorbing base is relatively low. As the use time increases, the long-term load pressure on the base cushion layer will seriously reduce the elastic performance of the base cushion layer, resulting in a significant reduction in the shock absorption effect achieved by the base cushion layer.

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-6 The present invention is described in further detail.

[0026] See also Figure 1-3A device for reducing the vibration of a cone crusher comprises a bearing box 1 placed on the ground, a cavity 11 is arranged inside the bearing box 1, a pressure regulating unit 2 is arranged at the bottom of the cavity 11, and a buffer unit 3 matched with the pressure regulating unit 2 is arranged on the inner wall of the cavity 11; a pressure bearing unit 4 is movably arranged at the upper end of the pressure regulating unit 2, and a bearing plate 5 connected with the cone crusher is arranged at the upper end of the pressure bearing unit 4, and the bearing plate 5 is movably connected with the bearing box 1.

[0027] During installation, the device is placed at the designated position, and the cone crusher is fixed to the upper end of the bearing plate 5 by bolts; usually, the working position of the cone crusher does not move frequently. In order to further improve the shock absorption effect of the cone crusher when used in conjunction with the present invention, a foundation pit of a suitable size for the bearing box 1 can be reserved at the designated working position, and an operating position can be reserved to adjust the buffer strength of the pressure unit 4 by operating the pressure regulating unit 2. During specific installation, after the bearing box 1 is fixedly set inside the foundation pit, the cone crusher is fixed to the upper end of the bearing plate 5 by bolts; when the cone crusher is in use, the pressure unit 4 and the buffer unit 3 cooperate with each other to achieve shock absorption of the working cone crusher, thereby ensuring the stable operation of the cone crusher.

[0028] See also Figure 3 and Figure 6 A sink 12 is provided at the center position of the bottom of the carrying box 1, and the pressure regulating unit 2 includes a rotating shaft 21 rotatably provided at the center position of the sink 12, and a cross plate 22 is fixedly provided on the bottom wall of the cavity 11, and the upper end of the rotating shaft 21 passes through the center position of the cross plate 22, and the rotating shaft 21 and the cross plate 22 are connected by a bearing, and the circumferential outer wall of the rotating shaft 21 is provided with a threaded groove at the part above the cross plate 22, and a pressure regulating plate 23 is threadedly provided at the threaded groove, and the upper end surface of the cross plate 22 is evenly provided with air holes 221, and the lower end of the pressure regulating plate 23 is connected to the corresponding position of the air hole 221, and the lower end of the piston rod 24 is provided with a piston 25 located inside the air hole 221; when the pressure regulating plate 23 is controlled to move up and down, the internal air pressure intensity of the air hole 221 can be changed by adjusting the internal gas volume of the air hole 221, so as to facilitate the adjustment of the later shock absorption force of the pressure regulating plate 23 to adapt to the vibration frequency of the cone crusher.

[0029] See also Figure 1 , Figure 3 and Figure 6 A gear 26 is fixedly provided on the part of the circumferential outer wall of the rotating shaft 21 located in the sink 12; an adjusting rod 27 is rotatably provided on the side wall of the sink 12 of the carrying box 1, and a spiral groove is opened on the adjusting rod 27 for meshing with the gear 26, and the other end of the adjusting rod 27 passes through the outside of the carrying box 1.

[0030] When the height of the pressure regulating plate 23 is adjusted, the existing tool is used to operate the adjusting rod 27 to rotate, and the gear 26 is used to drive the rotating shaft 21 to rotate to control the lifting and lowering of the pressure regulating plate 23; when the pressure regulating plate 23 rises, due to the compression of the buffer spring 46, the buffer distance of the pressure-bearing unit 4 becomes shorter, and the buffer strength of the pressure-bearing unit 4 increases. When the pressure regulating plate 23 descends, the buffer strength of the pressure-bearing unit 4 weakens, which can be adjusted according to the crushing frequency of the cone crusher, so that the vibration of the cone crusher can be offset and reduced through the mutual cooperation of the pressure-bearing unit 4 and the buffer unit 3.

[0031] See also Figure 3 , Figure 4 and Figure 7 The inner side wall of the cavity 11 of the carrying box 1 is provided with a card slot 14, and the two sides of the card slot 14 are symmetrically provided with a limit slot 13 connected thereto; the buffer unit 3 includes a rubber corrugated strip 31 arranged inside the limit slot 13, and the inside of the card slot 14 is evenly provided with a movable rod 32 through a movable connection. The movable rod 32 passes through the side wall of the cavity 11, and a pressure strip 33 is arranged at one end of the movable rod 32 located inside the cavity 11, and the movable rod 32 is located outside the cavity 11. One end of the movable rod 32 is provided with an end cap 34, and a section of the circumferential outer wall of all the movable rods 32 on the same side is located outside the cavity 11 and is commonly sleeved with a limit sleeve 35. The limit sleeve 35 is fixedly mounted on the outer wall of the carrying box 1, and the outer wall of the movable rod 32 is provided with a limit plate 36 located inside the limit sleeve 35. A spring sleeved on the outer wall of the movable rod 32 is connected between the limit plate 36 and the inner side wall of the limit sleeve 35 close to the end cap 34, and the end cap 34 is located outside the limit sleeve 35.

[0032] See also Figure 3 The pressure strip 33 and the rubber wave strip 31 cooperate with the pressure regulating plate 23, and the lower side of the end surface where the pressure regulating plate 23 and the pressure strip 33 cooperate with each other is an arc-shaped chamfered structure. When the pressure regulating plate 23 moves downward, the arc-shaped chamfered structure on its lower side will squeeze the pressure strip 33, and the pressure strip 33 drives the movable rod 32, the end cap 34, and the limit plate 36 to move horizontally synchronously. The limit plate 36 squeezes the spring. After the pressure regulating plate 23 is separated from the pressure strip 33, the pressure strip 33 is reset under the action of the spring rebound force; when the pressure regulating plate 23 needs to move upward, the end cap 34 is first pulled outward horizontally so that the pressure strip 33 will not block the pressure regulating plate 23 from moving upward.

[0033] Since the pressure regulating plate 23 can offset the vibration of the cone crusher during operation while bearing part of the load of the cone crusher, in order to distribute the load of the pressure regulating plate 23, the bearing capacity of the pressure regulating plate 23 on the peripheral side is increased by the pressure bearing strips 33 on the peripheral side to avoid the load acting entirely on the center position of the pressure regulating plate 23 and causing damage to the position where it is connected to the threaded section of the rotating shaft 21. The vibration of the cone crusher during operation will be partially offset by the rubber wave strips 31 in contact with the pressure regulating plate 23.

[0034] See also Figure 2 and Figure 6 The pressure-bearing unit 4 includes a receiving sleeve 41 arranged at the upper end of the pressure regulating plate 23, and the inner wall of the receiving sleeve 41 is evenly provided with four strip grooves 42. A pressure rod 43 is arranged inside the strip groove 42 through a pin shaft, and a shock-absorbing assembly 44 is arranged at the bottom of the strip groove 42, and the upper end of the shock-absorbing assembly 44 is in contact with the lower end of the pressure rod 43.

[0035] See also Figure 5 and Figure 6 The pressure-bearing unit 4 also includes a lower pressure sleeve 45 arranged at the center position of the lower end of the bearing plate 5, and the lower end of the lower pressure sleeve 45 is evenly provided with auxiliary grooves matching with the pressure rods 43, and the ends of the four pressure rods 43 close to each other are all located inside the auxiliary grooves, and a buffer spring 46 is arranged at the center position of the upper end of the pressure regulating plate 23, and the buffer spring 46 is located at the lower side of the four pressure rods 43.

[0036] See also Figure 6 The pressure unit 4 further includes a touch plate 47 disposed on the lower end surface of the bearing plate 5 and located directly above the pressure rod 43 . The lower end surface of the touch plate 47 is provided with a ball that cooperates with one end of the pressure rod 43 located inside the strip groove 42 .

[0037] See also Figure 2 and Figure 6 Circular mounting holes are provided at the four corner positions of the upper end surface of the carrying box 1 and the four side center positions of the upper end surface of the receiving sleeve 41. Shock-absorbing components 44 are also provided inside the circular mounting holes. The structures of the shock-absorbing components 44 in the circular mounting holes on the carrying box 1, the shock-absorbing components 44 in the circular mounting holes on the receiving sleeve 41, and the shock-absorbing components 44 in the strip groove 42 are the same, but the sizes are different.

[0038] When the cone crusher is installed on the present invention and works, the vibration generated by the cone crusher will first act on the bearing plate 5. At this time, primary shock absorption is performed through the bearing box 1 and the multiple shock-absorbing components 44 on the receiving sleeve 41. As the bearing plate 5 is pressed down, the pressure rod 43 is pressed down by the lower pressure sleeve 45 and the buffer spring 46 is compressed to achieve secondary shock absorption offset. During the shock absorption offset process, the buffer spring 46 continues to shrink and deform. At the same time, the touch plate 47 is pressed against the other end of the pressure rod 43. When the touch plate 47 presses the pressure rod 43, the lower end of the pressure rod 43 will cooperate with the shock-absorbing component 44 in the strip groove 42. At the same time, the pressure of the touch plate 47 on the pressure rod 43 will make the other end of the pressure rod 43 have an upward supporting force on the lower pressure sleeve 45, thereby further completing the shock absorption. The shock absorption effect is improved through multi-stage shock absorption.

[0039] See also Figure 6 The shock absorbing assembly 44 includes an upper connecting plate 441 and a lower connecting plate 442, and a multi-layer rubber shock absorbing layer 443 located between the upper connecting plate 441 and the lower connecting plate 442; the upper end of the upper connecting plate 441 in the shock absorbing assembly 44 inside the strip groove 42 is provided with a movable bead 444 that rolls in contact with the lower end surface of the pressure rod 43; the inner bottom wall of the strip groove 42 is fixedly connected to the corresponding lower connecting plate 442, and the lower end of the bearing plate 5 is fixedly connected to the corresponding upper connecting plate 441; the multi-layer rubber shock absorbing layer 443 can effectively offset the vibration and lateral torsion generated during the operation of the cone crusher, and further improve the stability of the cone crusher during operation.
