Operation principle of the invention is：
Control system receives conveyer belt lays and releases order, and one-level blocking mechanism action, hydraulic power unit is stepped up oil
Pressure, to the fuel feeding of locking pillar 6, disc spring group 7 is compressed, and reduces the clamping force of one-level blocking mechanism and tends to critical condition, be i.e. wedge shape
Tight lock part is contacted all the time with conveyer belt 14, downslide component of the coupling mechanism force less than conveyer belt 14.Hydraulic power unit is to clamping cylinder simultaneously
10 fuel feeding is reduced, and the tight mechanism of secondary latch reduces to the chucking power of conveyer belt 14, conveyer belt 14 under self gravitation effect, gradually
Glide, when conveyer belt 14 lays release, two grades of clamp systems are in critical condition, i.e., upper dynamic clamping part 11 begins with conveyer belt 14
Terminating is touched, the gliding speed of the clamping force control conveyer belt 14 of the tight mechanism of secondary latch.
During conveyer belt lays release, 14 times slip velocitys of real-time detection conveyer belt of velocity sensor 13 of control system
Degree, when velocity amplitude exceeds setting range, the tight mechanism of control system control secondary latch gradually increases clamping force to reduce conveyer belt
14 gliding speed, keeps it in the range of a stationary value.In the process, if conveyer belt 14 has special wanting to temperature
Ask, the temperature of conveyer belt is detected using temperature sensor 9, control system is reduced because of friction by controlling circulating cooling system
Influence of the heat to conveyer belt 14.
After conveyer belt 14 discharges in place, control system sends instruction, and the oil pressure of clamping cylinder 10 is increased to setting value, two
The clamping force that level retaining mechanism is produced is maximum, by conveyer belt 14 clamp and be maintained at upper dynamic clamping part 11 and under quiet clamping part 12 it
Between, the tight mechanism of secondary latch is in clamped condition.The oil pressure of the locking pillar 6 of one-level retaining mechanism is gradually decreased, and disc spring group 7 is stretched
Long, push rod 8 is moved down, and wedge lock portion swings, and conveyer belt 14 is clamped between quiet clamping part 2 and wedge lock portion.
The part do not addressed in the present invention uses or uses for reference prior art to be capable of achieving.
Specific embodiment described herein is only to spiritual example explanation of the invention.Belonging to of the invention
