[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cone crusher frame fastening device.

[0002]

2. Description of the Related Art A conventional fastening device of this type is shown in FIGS. That is, in the conventional fastening device, a number of holes are provided in both flanges 3 and 4 provided on the opposite ends of the lower frames 1 and 2 above the cone crusher, and bolt nuts 5 are inserted into these holes for fastening. Was.

[0003]

In the case of the above-described cone crusher, when the mantle and the bowl liner are worn, the upper frame 1 and the lower frame 2 must be disengaged for replacement. Therefore, it is necessary to loosen and remove the bolts and nuts 5 that fasten the upper frame 1 and the lower frame 2, but generally a cone crusher is installed outdoors and is exposed to wind and rain, and the bolts 5a and the nuts 5b rust. In many cases, a great deal of labor is required to loosen the nut 5b. In addition, there is a problem that since the number of the bolts and nuts 5 is large, the labor for loosening is further increased.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and to provide a frame fastening device for a cone crusher which can easily unfasten an upper frame and a lower frame with little labor. Aim.

[0005]

In order to achieve the above object, the present invention provides a cone crusher having a pair of left and right protrusions on the outer periphery of the lower end of the upper frame and the outer periphery of the upper end of the lower frame. A plurality of sets are provided in the circumferential direction at predetermined intervals so that the frames of the two frames face each other. On the upper surface of the projecting portion of the upper frame and the lower surface of the projecting portion of the lower frame, tapered surfaces are formed which are inclined inwardly toward the projecting portions to be paired with each other. A pair of left and right gripping members are disposed between the pair of projecting portions of the two frames so as to be able to approach and separate from each other, and the upper and lower ends of the gripping members hold the projecting portions of both frames. Gripping portions are formed, and the opposing inner surfaces of these gripping portions are formed with a tapered surface that is inclined outward in the direction of the protruding portion and is in sliding contact with the tapered surface of the protruding portion. The two gripping members are separated from each other between the two gripping members, and a wedge member for fitting the tapered surface of the gripping portion to the tapered surface of the projecting portion so as to grip the projecting portions of both frames by the gripping portion is fitted.

[0006]

When the two frames are fastened, a wedge member is fitted between the two gripping members disposed between the pair of projecting portions of the two frames. The fitting of the wedge member separates the two gripping members, and the tapered surface of the gripping portion comes into sliding contact with the tapered surface of the protruding portion so that the gripping portions grip the protruding portions of both frames. On the other hand, to release the fastening, the fitted wedge member is removed. As a result, the two gripping members approach each other, and the tapered surface of the gripping portion comes off the tapered surface of the protruding portion that has been slid.

FIG. 3 shows this gripped state. On the other hand, to release the fastening, the wedge member 40 to be fitted is removed by hitting the lower surface thereof with a hammer or the like. As a result, the two gripping members 25 and 26 approach each other, and the tapered surfaces 32 and 33 of the gripping portions 27 and 28 and the tapered surfaces 34 and 35 of the gripping portions 29 and 30 slide up to the tapered surfaces of the projecting portions 15 and 17. 20, 22 and protrusion 1
6 and 18 are removed from the tapered surfaces 21 and 23. As a result, the protruding portions formed by the gripping portions 27 and 28 of the gripping members 25 and 26 and the gripping portions 29 and 30
The gripping of the projections 15, 18 and the projections 16, 18 is released.

FIG. 5 shows another embodiment. Tapered surfaces formed on the opposite back surfaces of the gripping members 25 and 26 of this embodiment
Guide portions 50, 51 for slidably fitting the wedge member 40 are provided on both sides of the 37, 38, and the grip members 25,
The 26 is prevented from dropping to the front side. Also, gripping portions 27, 21 are formed on the front ends of the tapered surfaces 20, 21 and the tapered surfaces 22, 23 formed on the upper surfaces of the projecting portions 15, 16 and the lower surfaces of the projecting portions 17, 18.
A guide portion 53 is provided to slidably fit the gripping portions 29 and the gripping portions 28 and 30, and the gripping portions 27, 28, 29 and 30 of the gripping members 25 and 26 fall off to the front side of the gripping members 25 and 26. Is to be prevented.

FIG. 6 shows still another embodiment. On the front surfaces of the gripping members 25, 26 and the wedge member 40 of this embodiment, a rectangular steel plate 55 is fixed by inserting a long hole 57 into a bolt 56, and the wedge member 40 falls off to the front side of the gripping members 25, 26. Is to be prevented. In these embodiments, since the configuration of the other parts is substantially the same as that of the above-described embodiment, the same reference numerals are given to the same parts, and the description will be omitted.

[0012]

Since the present invention has the above-described structure, the upper frame and the lower frame can be easily fastened by driving the wedge member between the gripping members with a hammer or the like so as to be fitted. The above-mentioned connection can be easily released by hitting the wedge member from the opposite side with a hammer or the like, and such work can be performed only at a plurality of locations in the circumferential direction. Significantly less. Moreover, even if the wedge member and the gripping member are rusted, the fastening can be released by rotating the wedge member from the side opposite to the driving side instead of rotating it like a conventional bolt and nut,
There is an excellent effect that workability is much better.
