Description

Technical Field

[0001] This utility model relates to the technical field of cone crusher equipment, specifically to a fixing device for a moving cone liner. Background Technology

[0002] In cone crushers, the moving cone liner is one of the main wear parts. Once the moving cone liner reaches its wear life, it needs to be replaced immediately, otherwise it will cause damage to the internal components of the cone crusher. The wear life of the moving cone liner mainly depends on the degree of abrasion of the material. When crushing highly abrasive materials such as iron ore, basalt, and pebbles, the moving cone liner will need to be replaced very frequently. To address this, the utility model patent with publication number CN210522590U provides a locking mechanism for the moving cone liner of a cone crusher. The moving cone liner locking mechanism provided by this utility model patent requires the cutting ring to be cut with an oxy-fuel cutter to release the pressure at the moving cone nut when replacing the moving cone liner. Then, a disassembly wrench is inserted into the groove of the moving cone nut, and the moving cone nut is rotated to loosen and remove it, thereby releasing the locking and fixing of the moving cone liner. However, in actual operation on the construction site, it was found that since the moving cone nut is directly threaded onto the moving cone, it will become increasingly tight during the crushing process. As a result, it is time-consuming and laborious for maintenance personnel to loosen and disassemble the moving cone nut manually. Furthermore, the need to cut the cutting ring will further increase the overall workload and labor intensity of the maintenance personnel. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a device for fixing a moving cone liner by using a pressure ring to press the moving cone liner and locking it with a first locking component, so that the moving cone liner does not need to be disassembled by gas cutting, and the disassembly is easier and simpler, saving time and effort.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a fixing device for a moving cone liner, comprising a moving cone nut, a pressure ring, and a protective cap. The moving cone nut is detachably installed on the top of the moving cone body. The pressure ring is detachably fitted onto the upper end of the moving cone nut through a first locking assembly, and the annular bottom surface of the pressure ring abuts against and fits against the annular top surface of the moving cone liner to lock and fix the moving cone liner onto the moving cone body. The protective cap is detachably fitted onto the pressure ring through a second locking assembly and covers the pressure ring and the first locking assembly.

[0005] Furthermore, the movable cone nut includes a locking stud and a connecting top plate fixedly disposed at the top of the locking stud. The top of the movable cone is provided with a first threaded hole that is adapted to the locking stud. The locking stud is threadedly connected to the first threaded hole. A gap is provided between the lower end face of the connecting top plate and the top face of the movable cone.

[0006] Furthermore, the first locking assembly includes multiple double-ended studs, multiple locking nuts, and multiple self-locking washers. The pressure ring is provided with multiple first through holes spaced apart along its circumference, and the moving tapered nut is provided with multiple second threaded holes spaced apart along its circumference. The multiple double-ended studs, multiple locking nuts, multiple self-locking washers, multiple first through holes, and multiple second threaded holes are arranged in a one-to-one correspondence. The double-ended studs are inserted into the first through holes. The bottom end of the double-ended studs extends downward and passes through the first through hole and is threadedly connected to the second threaded hole on the moving tapered nut. The top end of the double-ended studs extends upward and passes through the first through hole and passes through the self-locking washer before being threadedly connected to the locking nut.

[0007] Furthermore, the second locking assembly includes multiple locking bolts and multiple locking washers. The protective cap is provided with multiple second through holes spaced apart along its circumference, and the pressure ring is provided with multiple third threaded holes spaced apart along its circumference. The multiple locking bolts, multiple locking washers, multiple second through holes and multiple third threaded holes are arranged in a one-to-one correspondence. The locking bolts pass through the locking washers and the second through holes in sequence and are threadedly connected to the third threaded holes on the pressure ring.

[0008] Furthermore, a snap-fit ​​mechanism is provided between the pressure ring and the moving cone nut. The snap-fit ​​mechanism includes a snap block and a snap groove. The snap block is fixedly located on the upper end face of the moving cone nut, and the snap groove is located on the pressure ring. The snap block and the snap groove are adapted to each other and can be snapped into the snap groove.

[0009] Furthermore, the pressure ring is shaped like a frustum, narrower at the top and wider at the bottom. The pressure ring has a first cavity that opens downwards and forms an annular bottom surface at the bottom end. The outer circumferential surface of the pressure ring is an outer frustum surface, and the inner side of the bottom of the protective cap has an inner frustum surface that abuts and fits against the outer frustum surface.

[0010] Furthermore, the bottom edge of the protective cap is welded to the pressure ring section.

[0011] Furthermore, at least one positioning mechanism is provided between the protective cap and the pressure ring. The positioning mechanism includes a positioning block and a positioning groove.

[0013] Furthermore, the inner circumferential surface of the moving cone liner is provided with multiple annular contact surfaces that are spaced apart along its height direction and closely fit the outer circumferential surface of the moving cone.

[0014] As described above, the fixing device for the moving cone liner provided by this utility model has the following beneficial effects: By using a pressure ring to press the moving cone liner and locking it with the first locking component, the moving cone nut does not need to be removed when the pressure ring is disassembled, and there is no need to release the pressure at the pressure ring. Therefore, there is no need to set a cutting ring, thus eliminating the need to cut the cutting ring with gas, which helps to further reduce the overall workload and labor intensity of maintenance personnel. When the moving cone liner needs to be replaced, it is only necessary to first release the locking of the second locking component to the protective cap, and then the protective cap can be removed. Then, the locking of the first locking component to the pressure ring can be released, and the pressure ring can be removed. At this time, the moving cone liner can be disassembled, which is easier and simpler, and saves time and effort. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below through specific embodiments.

[0021] like Figures 1 to 4As shown, the fixing device for a movable cone liner 5 according to the present invention includes a movable cone nut 1, a pressure ring 2, and a protective cap 3. The movable cone nut 1 is detachably installed on the top of the movable cone body 6. The pressure ring 2 is detachably fitted onto the upper end of the movable cone nut 1 through a first locking assembly 4, and the annular bottom surface 24 of the pressure ring 2 abuts against and fits against the annular top surface of the movable cone liner 5 to lock and fix the movable cone liner 5 onto the movable cone body 6. The protective cap 3 is detachably fitted onto the pressure ring 2 through a second locking assembly 7 and covers the pressure ring 2 and the first locking assembly 4.

[0022] By using the pressure ring 2 to press the moving cone liner 5 and locking it with the first locking assembly 4, the moving cone nut 1 does not need to be disassembled when the pressure ring 2 is removed, and there is no need to release the pressure at the pressure ring 2. Therefore, there is no need to set a cutting ring, thus eliminating the need for gas cutting of the cutting ring. This helps to further reduce the overall workload and labor intensity of maintenance personnel. When the moving cone liner 5 needs to be replaced, simply release the locking of the second locking assembly 7 on the protective cap 3 first, and the protective cap 3 can be removed. Then, release the locking of the first locking assembly 4 on the pressure ring 2, and the pressure ring 2 can be removed. At this time, the moving cone liner 5 can be disassembled. The disassembly is easier and simpler, and saves time and effort.

[0023] The movable cone nut 1 includes a locking stud 11 and a connecting top plate 12 fixedly disposed on the top of the locking stud 11. The top of the movable cone 6 is provided with a first threaded hole 61 adapted to the locking stud 11. The locking stud 11 is threadedly connected to the first threaded hole 61. A gap 8 is provided between the lower end face of the connecting top plate 12 and the top face of the movable cone 6. Thus, when the cone crusher is running under load, a certain space can be left for the movable cone nut 1 to continue to tighten downward. Preferably, the gap 8 is 10-14mm.

[0024] The first locking assembly 4 includes multiple double-ended studs 41, multiple locking nuts 42, and multiple self-locking washers 43. The pressure ring 2 has multiple first through holes 21 spaced apart along its circumference, and the movable tapered nut 1 has multiple second threaded holes 121 spaced apart along its circumference. The multiple double-ended studs 41, multiple locking nuts 42, multiple self-locking washers 43, multiple first through holes 21, and multiple second threaded holes 121 are arranged in a one-to-one correspondence. The double-ended studs 41 pass through the first through holes 21, and the bottom end of the double-ended studs 41 extends downward and passes through the first through holes 21 and is aligned with the second threaded holes 121 on the movable tapered nut 1. The threaded hole 121 is threaded. The top of the double-ended stud 41 extends upward and passes through the first through hole 21 and through the self-locking washer 43 before being threadedly connected to the locking nut 42. Therefore, when it is necessary to disassemble the pressure ring 2, it is only necessary to loosen and remove multiple locking nuts 42 in sequence to release the locking fixation of the pressure ring 2. At this time, the pressure ring 2 can be easily removed to release the locking fixation of the moving cone liner 5. During the process of tightening the locking nut 42, there will be a downward pressure on the pressure ring 2 and an upward pressure on the moving cone nut 1, thereby making the threaded connection between the moving cone nut 1 and the moving cone 6 tighter.

[0025] Preferably, the number of the double-ended studs 41, the locking nuts 42, and the self-locking washers 43 are all 10-16.

[0026] Correspondingly, the second locking assembly 7 includes a plurality of locking bolts 71 and a plurality of locking washers 72. The protective cap 3 is provided with a plurality of second through holes 31 spaced apart along its circumference, and the pressure ring 2 is provided with a plurality of third threaded holes 22 spaced apart along its circumference. The plurality of locking bolts 71, the plurality of locking washers 72, the plurality of second through holes 31 and the plurality of third threaded holes 22 are arranged in a one-to-one correspondence. The locking bolts 71 pass through the locking washers 72 and the second through holes 31 in sequence and then engage with the pressure ring. The third threaded hole 22 on the 2 is threaded, which facilitates the locking and fixing of the protective cap 3 onto the pressure ring 2, and effectively protects the pressure ring 2 and the first locking assembly 4, avoiding direct impact from falling materials. When it is necessary to remove the protective cap 3, simply loosen and remove multiple locking bolts 71 in sequence to release the locking and fixing of the protective cap 3, and then the protective cap 3 can be easily removed. Preferably, the number of locking bolts 71 and locking washers 72 is 3-5.

[0027] A locking mechanism 91 is provided between the pressure ring 2 and the moving cone nut 1. The locking mechanism 91 includes a locking block 911 and a locking groove 912. The locking block 911 is fixedly disposed on the upper end face of the moving cone nut 1, and the locking groove 912 is disposed on the pressure ring 2. The locking block 911 is adapted to the locking groove 912 and can be detachably locked in the locking groove 912. This avoids the force generated during the crushing process of the cone crusher from directly acting on the double-ended stud 41, effectively preventing the double-ended stud 41 from shearing and breaking during the crushing process of the cone crusher. Preferably, the locking block 911 has a cross structure.

[0028] The pressure ring 2 is a frustum shape that is narrower at the top and wider at the bottom. The pressure ring 2 has a first cavity 23 that opens downwards and the bottom end of the pressure ring 2 forms the annular bottom surface 24. The outer circumferential surface of the pressure ring 2 is an outer frustum surface 25. The bottom inner side of the protective cap 3 is provided with an inner frustum surface 32 that abuts and fits against the outer frustum surface 25, thereby better ensuring a tight fit between the bottom of the protective cap 3 and the pressure ring 2.

[0029] The bottom edge of the protective cap 3 is welded to the pressure ring 2 section to further ensure the stability of the connection between the bottom of the protective cap 3 and the pressure ring 2.

[0030] At least one positioning mechanism 92 is provided between the protective cap 3 and the pressure ring 2. The positioning mechanism 92 includes a positioning block 921 and a positioning groove 922. The positioning block 921 is fixedly disposed on the pressure ring 2, and the positioning groove 922 is disposed on the protective cap 3. The positioning block 921 is adapted to the positioning groove 922 and can be separably embedded in the positioning groove 922, thereby facilitating the installation of the protective cap 3 and playing a corresponding positioning role, ensuring the quick and accurate installation of the protective cap 3. Preferably, the number of positioning mechanisms 92 is 2-3 and they are evenly spaced.

[0031] Correspondingly, the protective cap 3 is cylindrical, and the protective cap 3 has a second cavity 33 that opens downward. In addition, the top of the protective cap 3 is recessed inward and forms a groove 34 to accumulate material and form a material protective liner, thereby reducing the wear of the top of the protective cap 3 by falling material.

[0032] The inner circumferential surface of the moving cone liner 5 is provided with a plurality of annular bonding surfaces 51 that are spaced apart along its height direction and closely fit the outer circumferential surface of the moving cone 6, thereby effectively ensuring the stability of the moving cone liner 5 in the installation and bonding with the moving cone 6.

[0033] The method of using the fixing device for the movable cone liner 5 described in this utility model is as follows: When it is necessary to disassemble and replace the movable cone liner 5, first use an angle grinder to grind away the weld seam of the segment weld, then loosen and remove multiple locking bolts 71 in sequence to release the locking fixation of the protective cap 3. At this time, the protective cap 3 can be easily removed. Then, loosen and remove multiple locking nuts 42 in sequence to release the locking fixation of the pressure ring 2. At this time, the pressure ring 2 can be easily removed to release the locking fixation of the movable cone liner 5. At this time, the movable cone liner 5 can be replaced. After the moving cone liner 5 is replaced, first install the pressure ring 2 to press down the moving cone liner 5, and make the locking block 911 on the moving cone nut 1 lock into the locking groove 912 on the pressure ring 2. Then, place and tighten multiple locking nuts 42 in sequence to complete the locking and fixing of the pressure ring 2. Then, install the protective cap 3, and make the positioning block 921 on the pressure ring 2 embedded in the positioning groove 922 of the protective cap 3. Then, place and tighten multiple locking bolts 71 in sequence to complete the locking and fixing of the protective cap 3. Finally, weld the bottom edge of the protective cap 3 to the pressure ring 2.

[0034] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
