Description
Technical field
The present invention relates to holdback fields, concretely relate to a kind of hydraulic distance-limiting type holdback.
Background technique
The holdback that China's upper conveying belt type conveyer uses at present mainly has Non-contact backstop and type contact non-return device
Two kinds, if above two holdback is applied on mostly driving upper conveying belt type conveyer, usually in every set driving device all
One holdback is installed, thus, it is desirable that parts and components in each driving device are loaded in complete machine check to want in a basic balance,
Check torque on exactly every set holdback wants of substantially equal, and there is problems in actual operation:
1, when belt conveyor heavy duty parking or heavily loaded emergency braking, most of check torque that holdback is born
It all can not achieve equilibrium, or even will appear the load concentration of the overwhelming majority wherein on a holdback, cause the driving device
Holdback and relevant parts and components load increase, may cause these parts and components excess loads and damage, to make belt
Conveyer reliably even cannot cause driving by stopping brake, generate consequence very serious.
2, in the host design of belt conveyor, generally by the check torque coefficient in driving device when selecting holdback
Increase and select high standard holdback, check torque needed for individually bearing whole belt conveyor can be met, in this way
Not only the cost of equipment of complete machine had been increased, but also may cause other parts and components overload, to reduce complete machine check reliability.
3, traditional distance-limiting type holdback presses to friction plate group using adjusting screw rod and disc spring, friction plate after longtime running
It wears, frictional force reduces between friction plate, and check torque, which becomes smaller, be easy to cause check to fail, can only if check torque need to be re-calibrated
Returning factory-run school just can not automatic compensating.
4, it when belt conveyor ad hoc inspection and repair or other special circumstances need motor to need to invert, needs to tear open holdback
Lower motor ability antiport, time-consuming and laborious, labor intensity is too big.
