Description
Technical Field
The utility model relates to a nut component, concretely relates to top nut component of single cylinder cone crusher.
Background
The single-cylinder hydraulic cone crusher can be widely applied to the industrial fields of black, non-ferrous and non-metallic mines, sandstone materials and the like. The characteristics of large crushing force, high production efficiency, lamination crushing, uniform grain shape of a finished product, less consumption of consumable parts, low operation cost and the like enable the single-cylinder hydraulic cone crusher to play an indispensable important role in the crushing industry. The principle is that a pair of meshed gears drives an eccentric mechanism to drive a main shaft to do rotary swing motion, and materials in a crushing cavity are crushed by extrusion.
The top nut is an important part arranged on the main shaft, and the working mode of the top nut is that the top nut is screwed on the main shaft through self threads, so that the moving cone lining plate is pressed tightly.
In the operation process of single cylinder hydraulic cone crusher, the thing that is broken is hard ore, aggregate etc. usually, through the acceleration of outside feeder, rushes into broken chamber, and the top nut can receive impact and wearing and tearing this moment, and this is also the main damage form of top nut.
The top nut is worn by impact, which, in addition to the increased economic cost of replacing parts, also increases the maintenance time of the equipment. The top nut is usually designed with four outward bosses as force application points during disassembly, the bosses can be ground off due to long-time impact wear, and the top nut can be ground into a cylinder due to rotation of the main shaft. When the moving cone lining plate needs to be replaced, no force application point is used for unscrewing the top nut, an iron block is generally required to be welded on the top nut to increase the force application point, and when the moving cone lining plate is replaced, the iron block needs to be cut off.
SUMMERY OF THE UTILITY MODEL
The utility model provides a top nut component of single cylinder cone crusher installs wear-resisting dish on the top nut for protect the top nut, removable after wear-resisting dish wearing and tearing moreover.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a top nut component of a single-cylinder cone crusher comprises a top nut and a wear-resisting disc; the top nut top is equipped with the step of sinking, top nut circumference outwards stretches out a plurality of top nut bosss, wear-resisting dish also is equipped with the wear-resisting dish boss of outwards stretching out, wear-resisting dish cover is established on the step of sinking.
Further preferably, the wear plate is welded to the top nut.
Preferably, the top nut boss and the wear-resistant disc boss are provided with bolt holes and connected through bolts.
Further preferably, the wear-resistant disc is a circular ring formed by 4 arc-shaped wear-resistant sheets, and each arc-shaped wear-resistant sheet is provided with a wear-resistant disc boss. The wear-resisting disc is formed by combining 4 arc-shaped wear-resisting pieces, a main shaft does not need to be sleeved in during installation or disassembly, and the installation and the replacement are convenient.
Further preferably, the wear plate boss is provided with a downwardly extending side guard plate for protecting the top nut boss.
Further preferably, the wear-resistant disc is made of a wear-resistant material.
Further preferably, the top nut and the main shaft are screwed to press the moving cone lining plate.
Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses a set up wear-resisting dish protection top nut boss on the top nut and not worn and torn, can greatly promote work efficiency and reduce economic cost when later stage single cylinder hydraulic cone crusher maintains or need to change the movable cone welt. The wear-resistant disc is composed of the arc-shaped wear-resistant pieces and is convenient to replace, and the top nut boss can be better protected due to the fact that the side protection plate extending downwards is arranged on the wear-resistant disc boss.

Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Example 1
Referring to fig. 1-4, a top nut assembly of a single cylinder cone crusher comprises a top nut 2, a wear plate 1; 2 tops of top nut are equipped with step 5 that sinks, 2 circumference of top nut outwards stretch out 4 top nut bosss 7, wear-resisting dish 1 also is equipped with 4 wear-resisting dish bosss 8 that outwards stretch out, wear-resisting dish 1 cover is established on step 5 that sinks, and wear-resisting dish boss 8 stacks on top nut boss 7. Top nut 2 closes on main shaft 3 through the screw of self soon to compress tightly movable cone welt 4, wear-resisting dish 1 that sets up at 2 tops of top nut has then played the effect of protection top nut 2, and top nut 2 can not worn and torn in the ring of wear-resisting dish 1, and wear-resisting dish boss 8 then can protect top nut boss 7 not worn and torn, makes the later stage dismantle the maintenance very convenient. The top nut 2 is provided with the sunken step 5, so that the wear-resistant disc 1 is positioned conveniently, the wear-resistant disc 1 is more convenient to mount, and the top nut 2 cannot be added when the wear-resistant disc 1 is mounted. The wear-resistant disc 1 is welded on the top nut 2, and the wear-resistant disc 1 is fixed on the top nut 2 through bolts, so that the wear-resistant disc is convenient to replace.
Example 2
Referring to fig. 5 and 6, a top nut assembly of a single cylinder cone crusher comprises a top nut 2, a wear plate 1; 2 tops of top nut are equipped with step 5 that sinks, 2 circumference of top nut outwards stretches out a plurality of top nut bosss 7, wear-resisting dish 1 comprises 4 arc wear pad 9, and every arc wear pad 9 is equipped with the wear-resisting dish boss 8 that outwards stretches out, and bolt hole is seted up with wear-resisting dish boss 8 to each top nut boss 7, fixes 4 arc wear pad 9 on step 5 that sinks through the bolt respectively. When the annular integral wear-resistant disc 1 is disassembled and replaced, the wear-resistant disc 1 is taken out from the top end of the main shaft 3, and the replacement of the wear-resistant disc 1 is complicated. The wear-resisting disc 1 of this embodiment comprises 4 arc wear-resisting pieces 9, and the installation is changed conveniently. If the arc-shaped wear-resisting pieces 9 are not worn uniformly, the arc-shaped wear-resisting pieces 9 with high wear degree can be directly replaced, and other arc-shaped wear-resisting pieces 9 are not replaced, so that the cost can be saved.
The main reason for the difficulty in detaching the top nut 2 is that the top nut boss is worn, so it can be further improved on the basis of embodiments 1 and 2, and a side guard plate extending downwards is provided on the wear-resistant disc boss 8 for protecting the top nut boss. When the single cylinder cone crusher works, the top nut 2 rotates along with the main shaft, so that the side surface of the top nut boss 7 is abraded in the rotating process, the wear-resisting disc boss 8 is provided with a side protection plate extending downwards for protecting the side surface of the top nut boss 7, and the service life of the top nut boss 7 can be longer.
Of course, if the wear-resistant disc 1 is made of a wear-resistant material such as ultrahigh manganese steel or high manganese steel, the service life of the wear-resistant disc 1 is also increased, and the frequency of maintenance or replacement of the wear-resistant disc 1 can be reduced.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
