[Conventional technology]

FIGS. 3 to 6 show the structure of a frame of a conventional jaw crusher.

In FIG. 3, reference numeral 10 denotes a jaw crusher, 18 a front frame of the jaw crusher 10, 14 a movable member (swing jaw) of the jaw crusher 10, 34 a side frame of the jaw crusher 10, and the front frame 18 has fixed teeth. 16, the movable member 14 has movable teeth 12,
It is installed in a replaceable manner.

The upper part of the movable member 14 has a boss 15 , and a support shaft 20 coupled to the side frame 34 is fitted into the boss 15 .
is allowed to swing like a pendulum around the support shaft 20.

22 is an eccentric shaft supported by a bearing near the rear part of the side frame 34, and 24 is a flywheel. 26 is a pitman operated by rotation of the eccentric shaft 22, and the lower end of the pitman 26 is connected to toggle plates 28 and 30, and the toggle plate 28 is connected to the movable member 14,
The toggle plates 30 are each connected to a toggle block 32.

The rotation of the eccentric shaft 22 causes the pitman 26 to reciprocate in the vertical direction, and the swinging of the toggle plates 28 and 30 causes the movable member 14 to swing as described above. In this way, the object to be crushed is sandwiched between the fixed teeth 16 and the movable teeth 12, and a crushing action is performed.

FIG. 4 shows a front view of essential parts of the jaw crusher 10 shown in FIG. 3.

In FIG. 4, bearings 36, 36 are provided at the upper portions of the side frames 34, 34, respectively.
The bearings 36, 36 connect both ends of the support shaft 20, and the support shaft 20 is connected to the upper part of the side frames 34, 34 despite the swinging operation of the movable member 14.

FIG. 5 is a front view of essential parts of the frame as seen from inside the jaw crusher 10 of FIG. 3. FIG.

In FIG. 5, the bearing 36 provided on the upper part of the side frame 34 is divided into an upper bearing 36a and a lower bearing 36b, which are integrated by bolt connection. Upper bearing 36
A key groove 37 is provided on the inner surface of the support shaft 20, and the support shaft 20 is fixedly connected to the side frame 34 by being fixed to the upper bearing 36a via the key.

FIG. 6 is an enlarged sectional view of a main part of the support shaft 20 of the jaw crusher 10 of FIG. 3. FIG.

In FIG. 6, the support shaft 20 is connected to the upper bearing 36.
a, 36a and lower bearings 36b, 36b, and are fixedly coupled to the side frame 34,
The peripheral edge of the support shaft 20 is in contact with the bushes 39, 39 and is slidable on the boss 15. 14a,1
4a is a part of the reinforcing material of the movable member 14 surrounding the boss 15. Rings 40, 40 are provided between both ends of the bush 15 and the bearing 36 to facilitate mutual movement.

Thus, when the crushing action of the object to be crushed is performed in the frame of the conventional geo crusher shown in FIGS. by bending the supporting shaft 20 and the bearing 36 to bring about deflection.
The connection between the support shaft 20 and the side frame 34 is in a sliding state, while the lower end of the side frame 34 forms a fixed end connection with the foundation.

[Problem that the invention attempts to solve]

However, in the frame of the conventional geo crusher described above, when the object to be crushed is crushed, the force generated due to the crushing acts, and the fixed end connection with the foundation is maintained at the lower end of the frame. At the upper end of the frame, there is a sliding connection with the support shaft, which causes flexure under a cantilever beam, reducing the rigidity of the frame and reducing the durability of the frame. In addition, there was a problem in that the deflection was also transmitted to the eccentric shaft system, reducing the durability of the members of the eccentric shaft system.

The present invention solves these conventional problems, and provides an excellent geo-clutch that increases the rigidity of the frame and increases the durability of the members by connecting fixed ends at the upper and lower ends of the frame. The purpose is to provide a frame for

[Means for solving problems]

In order to achieve the above object, the present invention includes a support shaft for fitting a movable member, a pedestal for connecting the support shaft at the upper end of the frame, and a system for connecting both ends of the support shaft to the pedestal. consisting of a fastening means,
The upper and lower ends of the frame are fixedly connected to each other.

[Effect]

The present invention has the following effects due to the above configuration. In other words, the sliding state connection at the upper end of the frame can be eliminated, and the upper and lower ends can each be fixed end connections, increasing the rigidity of the frame without causing frame deflection, and increasing the durability of the member. can be done.

〔Example〕

FIGS. 1 and 2 show the structure of an embodiment of the present invention.

In FIGS. 1 and 2, the same components as those in FIGS. 3 to 6 are given the same reference numerals, and redundant explanation will be omitted.

In FIG. 1, the support shaft 20 is fitted with the movable member 14, and the support shaft 20 is connected at both ends to a pedestal 46 attached to the upper ends of the side frames 34, 34 by welding. .

In FIG. 2, both ends of the support shaft 20 are formed by cutting off a part of the round shaft to form a flat surface.
Both ends of the holder are placed on pedestals 46, 46, respectively, and are vertically tightly coupled using a plurality of bolts 50 as fastening means. In addition, the support shaft 20
Both end surfaces of the support shaft 20 and both end surfaces of the pedestals 46, 46 are connected to the support shaft 20 and the presser material 4 via the presser members 48, 48.
8 and 48 using a plurality of bolts 51,
Furthermore, the pedestals 46, 46 and the holding members 48, 48 are tightly fastened in the horizontal direction using a plurality of bolts, so that both ends of the support shaft 20 and the side frames 34, 34 are fixed. End-joined.

In FIG. 1, the lower ends of the side frames 34, 34 are secured to the foundation using foundation bolts 54, 54, respectively, and are fixed end coupled.

In this way, the upper and lower ends of the side frames 34, 34 are fixedly connected, forming a rigid frame structure with no movement of the nodes, and each member of the rigid frame, that is, the side frames 34, 34 and the support shaft 20 The rigidity and durability of the eccentric shaft system member can be increased, and the durability of the members of the eccentric shaft system can also be increased.

As is clear from the above embodiments, the present invention increases the rigidity of the frame without causing any deflection by connecting the upper and lower ends of the frame with fixed ends, thereby increasing the durability of the members. This has practical effects, such as significantly improving the reliability of geode crushers that operate under severe load conditions.
