Abstract

The utility model provides a cantilever crane nut, and relates to the field of crushers. The cantilever crane nut comprises a cantilever crane nut body and an old movable liner plate; the upper end face of the cantilever crane nut body is fixedly connected with the upper opening end face of the movable liner plate; the diameter of the upper opening end face of the movable liner plate is more than or equal to the diameter of the upper end face of the cantilever crane nut body; and the lower opening end face of the movable liner plate is more than the upper opening end face of the movable liner plate. By utilizing the cantilever crane nut, the outer edge of the upper end face of the cantilever crane nut body can be effectively protected, so that the service life is correspondingly prolonged; the maintenance time is saved; and the production cost is reduced.

Description

A kind of jib cap
[technical field]
The utility model relates to field of cracking machine, especially relates to a kind of jib cap that is used for guard circle conic crusher jib bearing.
[background technology]
Known; When using gyratory crusher; Need broken ore materials to be fed by the top, this can produce bigger impulsive force to the jib bearing upper surface in the gyratory crusher, protects the jib bearing so will between jib bearing upper end and charging aperture lower end, a jib cap be installed; The ore materials that is promptly fallen by charging aperture can be fallen the upper surface of jib cap earlier, and then falls into the circular cone fragmentation; At present, existing jib cap be above that end face be provided with one be convenient to pile up ore materials depression, thereby be utilized in the ore materials of piling up in this depression the jib cap is played a protective role, prolong the service life of jib cap with this; Find that in practical operation the upper surface outward flange of jib cap can't avoid the bump of ore materials, promptly the depression of jib cap upper surface can not be protected the profile of jib cap; And the impaired normal use that can have influence on whole jib cap of the profile of jib cap; Cause reduce the service life of jib cap, at this moment, if selection is keeped in repair then is time-consuming longer; If selection changes then cost is bigger, this has brought a lot of troubles to the user.
[summary of the invention]
In order to overcome the deficiency in the background technology, the utility model provides a kind of jib cap, and described jib cap can effectively be protected the outward flange of its body upper surface, thereby has prolonged service life accordingly, has saved maintenance time, has reduced production cost.
For realizing the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of jib cap, described jib cap comprise jib cap body and waste and old moving liner plate; Described jib cap body upper surface is fixedly connected the end face suitable for reading of moving liner plate; Described moving liner plate end face diameter suitable for reading is not less than the upper surface diameter of jib cap body, and the end opening end face diameter of moving liner plate is greater than the end face diameter suitable for reading of moving liner plate.
Described jib cap, described jib cap body upper surface is fixedly connected for welding with the end face suitable for reading of moving liner plate.
Described jib cap, described moving liner plate end face diameter suitable for reading is identical with the upper surface diameter of jib cap body, and the end face diameter suitable for reading of moving liner plate is less than the end opening end face diameter 50mm of moving liner plate.
Owing to adopt aforesaid technical scheme, the utlity model has following beneficial effect:
The moving liner plate of the described jib cap of the utility model utilization has effectively been protected the upper surface of jib cap body, has promptly avoided ore materials directly to fall on the outward flange of jib cap body, thereby has prolonged the service life of jib cap body accordingly; Simultaneously, be waste and old moving liner plate owing to what adopt, and moving liner plate convenient disassembly; When moving liner plate damages when excessive; Only need to change the waste and old moving liner plate of another piece and get final product, therefore, described jib cap can be saved maintenance time for the user; Reduce production costs, thus the corresponding economic well-being of workers and staff that improves the user.
[description of drawings]
Fig. 1 is the sketch map of the utility model.
Among the figure: 1, jib cap body; 2, moving liner plate; 3, end face suitable for reading; 4, end opening end face.
[specific embodiment]
Can explain the utility model in more detail through following embodiment, the purpose of open the utility model is intended to protect all variations and the improvement in the utility model scope, and the utility model is not limited to following embodiment;
In conjunction with accompanying drawing 1 described jib cap, described jib cap comprises jib cap body 1 and the used waste and old moving liner plate 2 of disintegrating machine; The end face suitable for reading 3 of described jib cap body 1 upper surface and moving liner plate 2 is fixedly connected by welding together, will move exactly that liner plate 2 back-offs are come and jib cap body 1 links together, thereby through the effective upper surfaces of protection jib cap bodies 1 of moving liner plate 2; Described moving liner plate 2 end face 3 diameters suitable for reading are not less than the upper surface diameter of jib cap body 1; End opening end face 4 diameters of moving liner plate 2 are greater than the end face diameter suitable for reading of moving liner plate 2; Thereby the end opening end face 4 through moving liner plate 2 has effectively blocked the outward flange of the upper surface of jib cap body 1, and the ore materials that causes to fall and break is pounded the upper surface outward flange less than jib cap body 1; Connect for ease of alignment; Can the upper surface diameter of described moving liner plate 2 end face 3 diameters suitable for reading and jib cap body 1 be made as same diameter; Simultaneously; For ease of blocking the outward flange of jib cap body 1 upper surface, end face suitable for reading 3 diameters that move liner plate 2 are made as the size less than moving liner plate 2 end opening end faces 4 diameter 50mm, thereby effectively block the ore materials of whereabouts.
When implementing the described jib cap of the utility model; Only need described jib cap is fixedly mounted on the upper end of jib bearing in the corresponding gyratory crusher; When ore materials can be fallen the groove that forms between moving liner plate and the jib cap body upper surface earlier when charging aperture falls in; Fall into circular cone by the outward flange of moving liner plate again after full and carry out fragmentation heaping then, avoid ore materials directly to pound dropping on the outer peripheral purpose in jib cap body upper surface thereby reached.
Carefully not stating in the above content is prior art partly, does not state so run business into particular one.
