Description

Technical Field

[0001] The utility model relates to the technical field of cone crushing equipment, in particular to a locking device for a movable cone lining of a cone crushing main machine. Background Art

[0002] In cone crushing equipment, the movable cone liner is one of the main vulnerable parts. Once it is found that the movable cone liner has reached its wear life, it needs to be replaced immediately, otherwise it will cause damage to the internal components of the cone main unit. The wear life of the movable cone liner mainly depends on the degree of abrasion of the material. If crushing highly abrasive materials such as iron ore, basalt, and pebbles, the movable cone liner will be replaced very frequently. For this reason, the utility model patent with the authorization publication number CN210522590U provides a locking mechanism for the movable cone liner of cone crushing equipment. The utility model patent provides a locking mechanism for the movable cone liner of the cone crushing equipment. When replacing the movable cone liner, the cutting ring must first be cut by gas cutting to release the pressure on the movable cone nut, and then the disassembly wrench must be inserted into the slot of the movable cone nut, and the movable cone nut must be rotated and loosened and removed to release the locking fixation of the movable cone liner. However, in actual operation on the construction site, it was found that since the movable cone nut is directly threaded onto the movable cone, the movable cone nut will become tighter and tighter during the crushing process. As a result, it is more time-consuming and labor-intensive for maintenance personnel to manually loosen and remove the movable cone nut. In addition, since the cutting ring needs to be cut, the overall workload and labor intensity of the maintenance personnel will be further increased. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a dynamic cone liner locking device for a cone crusher main unit, which can make the disassembly of the dynamic cone nut easier and simpler, save time and effort, and is conducive to further reducing the overall workload and labor intensity of maintenance personnel by changing the connection mode between the dynamic cone nut and the dynamic cone.

[0004] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows: a dynamic cone liner locking device of a cone crusher main unit, comprising a dynamic cone nut and a distributing plate detachably mounted on the top of the dynamic cone nut, a cavity running through the upper and lower ends of the dynamic cone nut is provided in the dynamic cone nut, a dynamic cone nut hub is connected to the inner surface of the cavity of the dynamic cone nut, a connecting mechanism is provided between the dynamic cone nut hub and the dynamic cone, the connecting mechanism is used to detachably mount the dynamic cone nut hub on the dynamic cone and make the bottom end of the dynamic cone nut abut against the top of the dynamic cone liner to lock and fix the dynamic cone liner.

[0005] Furthermore, the connecting mechanism is connected to the moving cone through a cone head seal body, the cone head seal body is arranged at the top of the moving cone and is located in the cavity, the moving cone nut hub is arranged above the cone head seal body and an adjustment cavity is provided between the two.

[0006] Furthermore, a circular embedding hole is provided at the top of the moving cone, and a circular insert that matches the circular embedding hole is fixed at the bottom of the cone head sealing body, and the circular insert is threadedly connected to the circular embedding hole.

[0007] Furthermore, the connecting mechanism includes multiple studs and multiple locking nuts. The dynamic cone nut hub is provided with connecting holes running through its upper and lower ends. There are multiple connecting holes and they are arranged along the circumferential direction of the dynamic cone nut hub. Studs are passed through the multiple connecting holes. The bottom end of the stud extends downward and passes through the connecting hole and is threadedly connected to the threaded hole at the top of the cone head sealing body. The top end of the stud extends upward and passes through the connecting hole and is threadedly connected to the locking nut.

[0008] Furthermore, the number of the connecting holes and the threaded holes is 10-14 and they are evenly arranged.

[0009] Furthermore, at least one clamping mechanism is provided between the dynamic cone nut hub and the cone head sealing body, and the clamping mechanism includes a matching clamping block and a clamping groove. The clamping block is fixedly arranged at the bottom end of the dynamic cone nut hub, and the clamping groove is arranged at the top end of the cone head sealing body. The clamping block is detachably clamped in the clamping groove.

[0010] Furthermore, the material distribution plate is detachably mounted on the moving cone nut plug by a plurality of locking bolts. The moving cone nut plug is connected to the inner surface of the cavity of the moving cone nut and is located above the moving cone nut hub. The moving cone nut plug is provided with a plurality of operating through holes that pass through its upper and lower ends and correspond one-to-one to a plurality of studs.

[0011] Furthermore, the number of the locking bolts is 4-8.

[0012] Furthermore, the movable cone nut plug is threadedly connected to the movable cone nut.

[0013] Furthermore, the movable cone nut hub is threadedly connected to the movable cone nut.

[0014] From the above description, it can be seen that the movable cone liner locking device of the cone crusher main unit provided by the present invention has the following beneficial effects: by changing the connection method between the movable cone nut and the movable cone, the two are no longer connected by a threaded connection method. Therefore, when removing the movable cone nut, there is no need to release the pressure on the movable cone nut, and thus there is no need to set a cutting ring. In this way, there is no need to cut the cutting ring by gas cutting, which is conducive to further reducing the overall workload and labor intensity of maintenance personnel. At the same time, in conjunction with the setting of the connecting mechanism, when it is necessary to remove the movable cone nut, it is only necessary to disassemble the connecting mechanism to release the stable connection between the movable cone nut and the movable cone, so that the movable cone nut can be lifted upward, which can make the removal of the movable cone nut easier and simpler, and save time and effort.

DETAILED DESCRIPTION

[0022] The present invention is further described below through specific implementation methods.

[0023] like Figures 1 to 6 As shown, the utility model describes a dynamic cone liner locking device for a cone crusher main unit, comprising a dynamic cone nut 1 and a distribution plate 2 detachably mounted on the top of the dynamic cone nut 1, wherein the dynamic cone nut 1 is provided with a cavity running through its upper and lower ends, and a dynamic cone nut hub 3 is connected to the inner surface of the cavity of the dynamic cone nut 1, and a connecting mechanism 4 is provided between the dynamic cone nut hub 3 and the dynamic cone 5, wherein the connecting mechanism 4 is used to detachably mount the dynamic cone nut hub 3 on the dynamic cone 5 and make the bottom end of the dynamic cone nut 1 abut against the top of the dynamic cone liner 6 to lock and fix the dynamic cone liner 6.

[0024] By changing the connection method between the movable cone nut 1 and the movable cone 5, the two are no longer connected by a threaded connection. Therefore, when disassembling the movable cone nut 1, there is no need to release the pressure on the movable cone nut 1, and thus there is no need to set a cutting ring. In this way, there is no need to cut the cutting ring by gas cutting, which is conducive to further reducing the overall workload and labor intensity of maintenance personnel. At the same time, in conjunction with the setting of the connecting mechanism 4, when it is necessary to disassemble the movable cone nut 1, it is only necessary to disassemble the connecting mechanism 4 to release the stable connection between the movable cone nut 1 and the movable cone 5, so that the movable cone nut 1 can be lifted upward, which can make the disassembly of the movable cone nut 1 easier and simpler, and save time and effort.

[0025] The connecting mechanism 4 is connected to the moving cone 5 through a cone head sealing body 7. The cone head sealing body 7 is arranged at the top of the moving cone 5 and is located in the cavity. The moving cone nut hub 3 is arranged above the cone head sealing body 7 and an adjustment cavity 33 is provided between the two, thereby leaving adjustment space for the moving cone nut 1 to further lock the moving cone liner 6. A circular embedding hole 51 is provided at the top of the moving cone 5, and a circular annular embedding block 71 is fixedly provided at the bottom end of the cone head sealing body 7, which is adapted to the circular embedding hole 51.

Accordingly, a first external thread is provided on the outer circumference of the circular annular embedding block 71, and the moving cone 5 is provided with a first internal thread adapted to the first external thread in the circular embedding hole 51, so that the cone head sealing body 7 and the moving cone 5 are threadedly connected as a whole.

[0026] The connecting mechanism 4 includes multiple studs 41 and multiple locking nuts 42. The dynamic cone nut hub 3 is provided with connecting holes 31 running through the upper and lower ends thereof. The connecting holes 31 are multiple and are arranged along the circumferential direction of the dynamic cone nut hub 3. The multiple connecting holes 31 are all penetrated by the studs 41. The bottom ends of the studs 41 extend downward and pass through the connecting holes 31 and are threadedly connected to the threaded holes 72 at the top of the cone head sealing body 7. The top ends of the studs 41 extend upward and pass through the connecting holes 31 and are threadedly connected to the locking nuts 42. In addition, an anti-loosening gasket is provided between the locking nut 42 and the dynamic cone nut hub 3. Therefore, when it is necessary to disassemble the dynamic cone nut 1, it is only necessary to loosen and remove the locking nut 42 to release the stable connection between the dynamic cone nut 1 and the dynamic cone 5. At this time, the dynamic cone nut 1 can be lifted upward to release the locking fixation of the dynamic cone liner 6.

[0027] Preferably, the number of the connecting holes 31 and the threaded holes 72 are both 10-14 and are evenly arranged.

[0028] In addition, at least one clamping mechanism is provided between the dynamic cone nut hub 3 and the cone head seal 7, and the clamping mechanism includes a corresponding clamping block 32 and a clamping groove 73. The clamping block 32 is fixedly arranged at the bottom end of the dynamic cone nut hub 3, and the clamping groove 73 is arranged at the top end of the cone head seal 7. The clamping block 32 is detachably clamped in the clamping groove 73, effectively preventing the stud 41 from breaking during the crushing process. Preferably, the number of the clamping mechanisms is 1-3.

[0029] The distribution plate 2 is detachably mounted on the dynamic cone nut plug 9 by a plurality of locking bolts 8. The dynamic cone nut plug 9 is connected to the inner surface of the cavity of the dynamic cone nut 1 and is located above the dynamic cone nut hub 3, thereby facilitating the detachable installation between the distribution plate 2 and the dynamic cone nut 1. The dynamic cone nut plug 9 is provided with a plurality of operating through holes 91 that pass through its upper and lower ends and correspond one-to-one to the plurality of studs 41. Through the setting of the operating through holes 91, the sleeve can pass through the operating through holes 91 to operate and rotate the locking nut 42 to loosen or tighten the locking nut 42, so as to facilitate the subsequent disassembly and assembly of the dynamic cone nut 1. Preferably, the number of the locking bolts 8 is 4-8.

[0030] The dynamic cone nut plug 9 is threadedly connected to the dynamic cone nut 1, and accordingly, the outer circumferential surface of the dynamic cone nut plug 9 is provided with a second external thread, and the inner surface of the cavity of the dynamic cone nut 1 is provided with a second internal thread adapted to the second external thread, thereby facilitating the threaded connection of the dynamic cone nut plug 9 and the dynamic cone nut 1 into a whole, and the dynamic cone nut hub 3 is threadedly connected to the dynamic cone nut 1, and accordingly, the outer circumferential surface of the dynamic cone nut hub 3 is provided with a third external thread, and the inner surface of the cavity of the dynamic cone nut 1 is provided with a third internal thread adapted to the third external thread, thereby facilitating the threaded connection of the dynamic cone nut hub 3 and the dynamic cone nut 1 into a whole.

[0031] The method of using the movable cone liner locking device of the cone crusher main machine described in the present invention is as follows: when the movable cone liner 6 needs to be disassembled and replaced, first loosen and remove the locking bolt 8, thereby facilitating the removal of the material distribution plate 2 from the upper end of the movable cone nut 1, and then use a sleeve to pass through the operating through hole 91 on the movable cone nut plug 9 to loosen and remove the locking nut 42, thereby releasing the locking fixation of the movable cone nut 1, at this time, the movable cone nut 1 can be lifted upward and removed, thereby releasing the locking fixation of the movable cone liner 6, and then, the movable cone liner 6 can be replaced. After the replacement of the movable cone liner 6 is completed, the movable cone nut 1 can be hoisted to the upper end of the movable cone 5, and multiple double-headed The studs 41 correspond one-to-one to the multiple connecting holes 31 on the moving cone nut hub 3, and the upper ends of the studs 41 pass through the connecting holes 31, and the bottom end of the moving cone nut 1 abuts against the top of the moving cone liner 6. Then, a sleeve is used to pass through the operating through hole 91 on the moving cone nut plug 9 to tighten the locking nut 42 and install it on the corresponding stud 41, thereby playing a corresponding locking and fixing role on the moving cone nut 1, that is, playing a corresponding locking and fixing role on the moving cone liner 6. Then, the distribution plate 2 is placed on the top of the moving cone nut 1, and by tightening the locking bolt 8, the distribution plate 2 is locked and fixed on the moving cone nut plug 9, that is, a stable connection between the distribution plate 2 and the moving cone nut 1 is achieved.
