In the present embodiment, (1) devises new hydraulic control system, and this hydraulic control system is when hydraulic cylinder 21 action Hydraulic oil pump 26 is idle, it is only necessary to starts hydraulic oil pump 26 when hydraulic cylinder 21 is retracted, it is achieved that short time duty, reaches Energy-conservation effect；(2) have developed a set of standby breakage protection system independent of hydraulic control system, if single dependence liquid The thrust of cylinder pressure 21 realizes voussoir 16 and lower wedge block 18 locks belt 10, although substantially can meet the requirement of broken belt protector, But certain parts once in hydraulic system (such as hydraulic cylinder 21 or oil pipe line) fault, belt conveyor generation broken belt fault Time will be unable to be protected, when especially there is non-dominant hydraulic control system fault, operations staff is not easy to discover, and waits until Broken belt has had little time when occurring to process hydraulic system fault, and this will bring the biggest potential hazard to the operation of belt conveyor, And standby arranging of breakage protection system can effectively solve this problem；(3) super mangneto tensioning system is used to realize broken belt protector Action, action is the sensitiveest, can effectively contract protection short movement time；It is also provided with Breech block 34 to prevent super mangneto from drawing simultaneously Stretch the misoperation of system, effectively reduce the malfunction of system；First chute be arranged in frame and and belt between angle be 11 °, upper voussoir 16 along during the second chute 30 landing to the vibration force of frame 13 less than the 30% of permissible value.

Last it should be noted that, above example is only in order to illustrate technical scheme, rather than the present invention is protected Protecting the restriction of scope, although having made to explain to the present invention with reference to preferred embodiment, those of ordinary skill in the art should Work as understanding, technical scheme can be modified or equivalent, without deviating from the reality of technical solution of the present invention Matter and scope.
