The device comprises an air bag located in a locking cylinder body, wherein an inflationconnector is arranged at the upper part of the air bag and has an air return prevention function; a disc spring assembly is mounted in the cylinder body; a sliding disc is arranged between thedisc spring and the air bag; a sealing part is arranged between thesliding disc and the cylinder body; thedisc spring assembly is closely contacted with a piston in thecylinder body; a sealing ring is mounted between the piston and the cylinder body; an ejection rod and the piston are connected into a whole through threads; and a cylinder cap is connected with thecylinder body through threads.
Description
Technical field
The utility model relates to a kind of screw-threaded coupling device of gyratory crusher, especially adapts on gyratory crusher.
Background technique
The well-known broken facility of gyratory crusher have crushing ratio large, efficiency is high, power consumption is little, liner plate is long service time, product granularity is even, the low various features that waits of operating cost, be mainly used in mine, cement, the industrial departments such as building materials, to broken in various hard ores, operation in small, broken bits, in fragmentation process, locking cylinder is made seal failure because seal ring shakes, cause oil cylinder leakage of oil locking to be lost efficacy, finally cause equipment normally not use, shown in Fig. 2, push rod 1 is connected with piston 3 by screw thread, between oil cylinder housing 4 and piston, seal ring being housed seals, between cylinder cap 2 and oil cylinder housing 4 by scyewed joint, the top of oil cylinder housing 4 is processed with filler opening 102, in the time pouring pressure oil, push rod 1 stretches out under the effect of oil pressure, locking cylinder work, as shown in Figure 3, locking cylinder 2 is contained in the middle of locking swivel nut 3, between adjusting sleeve 1 and locking swivel nut 3 and fixation machine support body 4, connect at face 101 places by profile of tooth screw thread, when locking cylinder 2 is done the used time, locking swivel nut 3 is by jack-up, make to produce and push between the profile of tooth screw thread on profile of tooth screw thread and the fixation machine support body 4 in adjusting sleeve 1, thereby locking adjusting sleeve 1.Because broken operating mode is severe, within a short period of time, sealing was lost efficacy, and the performance of disintegrator will be subject to inevitable impact, and in order to ensure or to extend its working life, this programme proposes one solution effectively.
Summary of the invention
The purpose of this utility model provides a kind of screw-threaded coupling device of gyratory crusher for above-mentioned the deficiencies in the prior art.
For achieving the above object, the utility model can be taked following technical proposals:
The screw-threaded coupling device of a kind of gyratory crusher described in the utility model, it comprises the air bag that is positioned at locking cylinder cylinder body, inflation connected body is arranged at described air bag top, described connected body has the function that prevents return-air, dished spring assembly is contained in cylinder body, between dished spring assembly and air bag, there is a sliding plate, between described sliding plate and cylinder body, there is Sealing, piston close contact in described dished spring assembly and cylinder body, between described piston and cylinder body, seal ring is housed, integral by scyewed joint between push rod and piston, cylinder cap is connected with cylinder body by screw thread.
Described locking cylinder has air bag, dished spring assembly and jointly completes locking task.
After described air bag lost efficacy because of a variety of causes, be filled with high pressure liquid force feed to cylinder body, jointly complete locking work by described dished spring assembly, Sealing.
Positive progressive effect of the present utility model is, the advantages of simple of the screw-threaded coupling device of the utility model gyratory crusher effectively ensures to extend disintegrator service time.
Brief description of the drawings
Fig. 1 is the plan view of the screw-threaded coupling device of the utility model gyratory crusher.
Fig. 2 is the plan view of the locking cylinder structure of prior art.
Fig. 3 is the screw-threaded coupling device using effect figure of a kind of gyratory crusher of prior art
Embodiment
As shown in Figure 1, the screw-threaded coupling device of a kind of gyratory crusher described in the utility model, it comprises the air bag 7 that is positioned at locking cylinder cylinder body 6, inflation connected body 8 is arranged at described air bag 7 tops, described connected body 8 has the function that prevents return-air, dished spring assembly 5 is contained in cylinder body, between dished spring assembly 5 and air bag 7, there is a sliding plate 9, between described sliding plate 9 and cylinder body 6, there is Sealing 10, piston 4 close contacts in described dished spring assembly 5 and cylinder body, between described piston 4 and cylinder body 6, seal ring 3 is housed, integral by scyewed joint between push rod 1 and piston 4, cylinder cap 2 is connected with cylinder body 6 by screw thread.
Described locking cylinder has air bag 7, dished spring assembly 5 completes locking task jointly.
After described air bag 7 lost efficacy because of a variety of causes, be filled with high pressure liquid force feed to cylinder body 6, jointly complete locking work by described dished spring assembly 5, Sealing 10.
Working principle: in the time that needs are locked, pour pressurized gas by inflation connected body to air bag, under the effect of pressurized gas, compress successively dished spring assembly, piston and push rod stretch out, and when inflation reaches after setup pressure value, locking work completes; In use for some time, due to a variety of causes airbag fails, by connected body to pouring high pressure liquid force feed in cylinder body, on high pressure liquid force feed direct effect lower sliding disc, compress successively dished spring assembly, piston and push rod stretch out, when oil pressure reaches after setup pressure value, locking work completes; Sealing between sliding plate and cylinder body had lost efficacy again, also had the seal ring between piston and cylinder body to seal, from connected body to pouring high pressure liquid force feed in cylinder body, this is that high pressure liquid force feed acts directly on piston, when oil pressure reaches after setting value, keep oil pressure, locking work completes.After improving, locking device has three kinds of locking functions, can effectively extend the service time of locking device.
Although more than described the embodiment of this programme, it should be appreciated by those skilled in the art that this only illustrates, all should be in protection domain in principle of the present utility model and essence, concrete mode of execution can change to some extent.
