Abstract
The utility model belongs to the technical field of mining, and particularly relates to a leather container type locking cylinder for a cone crusher. The leather container type locking cylinder comprises a locking oil cylinder body, a piston, a snap ring, a wear ring and a support ring, wherein the piston, the snap ring, the wear ring and the support ring are arranged at the interior of the locking oil cylinder body. The leather container type locking cylinder is characterized in that a leather container is arranged at an oil inlet part in the inner side of the locking oil cylinder body. Due to the fact that the leather container is embedded into the interior of the locking oil cylinder body, oil leakage due to a wear clearance between the piston and the locking oil cylinder body cannot be caused, so that the locking oil cylinder body achieves the effects of safety and environmental protection; moreover, due to the existence of the leather container, the service life of the locking cylinder is prolonged, the locking cylinder cannot depressurize due to the clearance generated by the wear of the wear ring, and the locking pressure can be kept continuously. The leather container type locking cylinder is simple in structure, convenient to use, easy to manufacture and low in cost.
Description
Technical field
The utility model belongs to mining technique field, especially relates to a kind of skin courage formula locking cylinder for gyratory crusher.
Background technology
Locking cylinder on gyratory crusher is to be placed between fixed cone of cone crusher and adjustment ring, plays and adjustment ring is fixed and is locked at the effect of determining on cone.The operation principle of current locking cylinder is the reciprocating motion that adopts piston type cylinder body, by injection liquid force feed in cylinder body, piston is moved up, and utilizes locking cylinder that adjustment ring is connected with fixed cone, realizes adjustment ring in fixing, the locking determined on cone.Because locking cylinder adopts sealing ring, seal, when the long-time high-strength working of locking cylinder process, the sealing ring in locking cylinder can be revealed because the factors such as wearing and tearing produce, and cannot keep locking pressure, loses locking effect.Generally in this case, need to locking cylinder, place under repair immediately, each maintenance need to be changed whole seals.Because locking cylinder itself belongs to precision part, comparatively complicated when repairing, and also the time is longer, if do not have spare part to change in time, can affect the normal work of disintegrating machine, reduces the operating efficiency of disintegrating machine.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, skin courage formula locking cylinder for gyratory crusher easy to use, because this kind of locking cylinder studs with skin courage in cylinder interior, not only can guarantee that locking cylinder does not occur leakage phenomenon when work, and can also play environmental-protection function.
The purpose of this utility model realizes by following technical proposals:
Skin courage formula locking cylinder for gyratory crusher of the present utility model, comprise locking cylinder cylinder block, be located at piston, snap ring, wear ring and the support ring of this locking cylinder cylinder block inside, it is characterized in that fuel feed hole position is provided with skin courage inside described locking cylinder cylinder block.
Advantage of the present utility model:
Skin courage formula locking cylinder for gyratory crusher of the present utility model, owing to studding with skin courage in locking cylinder cylinder block inside, makes locking cylinder cylinder block can not cause leakage of oil because of the wearing clearance of piston and locking cylinder cylinder block, plays the effect of safety and environmental protection; Meanwhile, due to the existence of skin courage, locking cylinder is extended service life, can not make locking cylinder pressure release because of the gap that wear ring wearing and tearing produce, can continue to keep locking pressure.The utility model is simple in structure, easy to use, is easy to manufacture, with low cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, further illustrate the specific embodiment of the present utility model.
As shown in Figure 1, skin courage formula locking cylinder for gyratory crusher of the present utility model, comprise locking cylinder cylinder block 3, be located at piston 1, snap ring 2, wear ring 4 and the support ring 5 of these locking cylinder cylinder block 3 inside, it is characterized in that being provided with skin courage 6 at described locking cylinder cylinder block 3 fuel feed hole positions, inner side.
At locking cylinder cylinder block 3 fuel feed hole positions, inner side, skin courage 6 is installed, hydraulic oil is not directly contacted with piston 1, but enter skin courage 6, along with the hydraulic oil entering in skin courage 6 is on the increase, skin courage 6 can be attached on locking cylinder cylinder block 3 inwalls and piston 1 lower surface, and then promotes upwards action of piston 1, when overhang reaches certain value, locking cylinder is crusher fixed cone and adjustment ring jam-packed, thereby realizes the locking effect of locking cylinder to adjustment ring.With respect to common locking cylinder, as long as skin courage 6 does not damage, locking cylinder just can not lose efficacy because of leakage, thus the service life of having improved locking cylinder.
The utility model, owing to studding with skin courage 6 in locking cylinder cylinder block 3 inside, makes locking cylinder cylinder block 3 can not cause leakage of oil with the wearing clearance of locking cylinder cylinder block 3 because of piston 1, plays the effect of safety and environmental protection; Meanwhile, due to the existence of skin courage 6, locking cylinder is extended service life, can not make locking cylinder pressure release because of the gap that wear ring wearing and tearing produce, can continue to keep locking pressure.The utility model is simple in structure, easy to use, is easy to manufacture, with low cost.
