a moving inclined rod which is positioned at the lower side of the belt, the upper end of the moving inclined rod is fixedly connected with one end of the moving cross rod,
a gravity hammer fixed at the lower end of the motion diagonal rod,
the rotating mechanism is arranged in the middle of the moving inclined rod, the moving inclined rod is fixed on a cross beam of the large-scale belt conveyor, after downward stress of the pulley disappears due to the fact that the upper belt is broken, the moving inclined rod rotates through a connecting point of the rotating mechanism and the cross beam, then the gravity hammer rotates and shifts a travel switch connected with the belt conveyor, and the belt conveyor is forced to stop.
Further, the rotating mechanism includes:
the front clamping plate and the rear clamping plate are respectively clamped at the front side and the rear side of the cross beam and are fixed on the cross beam through bolts,
the left ear plate is arranged in the front-back direction, the rear end of the left ear plate is fixed on the front wall of the front clamping plate,
a right ear plate arranged parallel to the left ear plate and having its rear end fixed on the front wall of the front clamping plate,
a fixed rod moving left and right, both ends of the fixed rod are respectively fixedly connected with the left ear plate and the right ear plate,
and the side wall of the fixed bolt is fixed at the middle part of the moving inclined rod, and the fixed bolt is sleeved at the middle part of the fixed rod and used for rotating the moving inclined rod along the fixed rod through the fixed bolt after the stress of the pulley disappears, so that the moving inclined rod is vertically arranged, and the gravity hammer at the lower end of the moving inclined rod is forced to toggle the travel switch.
The beneficial effects of the utility model are that: the utility model discloses utilize lever principle, in time the stall behind gravity hammer touching travel switch, the downside of belt is withstood to the upside of pulley, and when last belt broken string, the gravity hammer droops, and touching travel switch to accomplish in time the stall, prevent the accident and enlarge the ization, reduced the accident rate, can effectively prevent the accident and enlarge the ization, and strengthened the factor of safety of big belt operation.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model discloses a belt breakage protection device to large-scale belt conveyor, as shown in fig. 1, including motion horizontal pole 1, pulley 2, motion down tube 3, gravity hammer 4, slewing mechanism 5.
The horizontal setting of motion horizontal pole 1, motion horizontal pole 1 is located the belt downside, and pulley 2 is located the belt downside, and 2 covers of pulley are established on motion horizontal pole 1, and pulley 2 is used for propping the belt downside, rotates along with the belt on motion horizontal pole 1, and motion down tube 3 is located the belt downside, and the slope of motion down tube 3 sets up, the upper end of motion down tube 3 and the one end fixed connection of motion horizontal pole 1.
Through setting up slewing mechanism 5 for the back appears the fracture suddenly on the upper belt of large-scale belt feeder, originally presses the pressure of 2 upsides of pulley and disappears suddenly, because the effect of the gravity hammer 4 of 3 lower extreme fixed connection of motion down tube, forces the upper end of motion down tube 3 to upwards rotate, and keeps the vertical state, rotates the in-process at motion down tube 3 and uses slewing mechanism 5 to rotate as the center, and when rotating to the vertical state, travel switch is stirred to gravity hammer 4, makes the belt feeder stop, accomplishes the protection action.
As shown in fig. 2, the rotating mechanism 5 includes: the front clamping plate 6 and the rear clamping plate 7, the left ear plate 8, the right ear plate 9, the fixing rod 10 and the fixing bolt 11 are respectively clamped on the front side and the rear side of the beam, and the front clamping plate 6 and the rear clamping plate 7 fix the front clamping plate 6 and the rear clamping plate 7 on the beam through bolts.
The front and back trend of left otic placode 8 sets up, and the rear end of left otic placode 8 is fixed on the antetheca of front plate 6, and right otic placode 9 sets up with left otic placode 8 parallel, and the rear end of right otic placode 9 is fixed on the antetheca of front plate 6, and the trend is about dead lever 10, the both ends of dead lever 10 respectively with left otic placode 8 and right otic placode 9 fixed connection.
The lateral wall of fixing bolt 11 is fixed in the middle part of motion down tube 3, and fixing bolt 11 cover is established in the middle part of dead lever 10, and fixing bolt 11 is used for after the atress of pulley 2 disappears, rotates along dead lever 10 at motion down tube 3 through fixing bolt 11, and then makes the vertical setting of motion down tube 3, forces the gravity hammer 4 of its lower extreme to stir travel switch.
The protection of broken belt of large belt is always important to protect the normal operation of large belt and prevent accident from expanding. The broken belt is protected by the belt deviation at two sides, namely a travel switch and personnel patrol when the equipment runs. Normally, disconnected area is along with the belt support groove, and the belt support groove touches the protection after and parks, but because belt checkpost fracture, carries the local overweight of thing, and the disconnected area that the belt caused is blocked to stone debris can't in time discover, just leads to the enlarged scale of disconnected area accident, several meters to several hundred meters promptly. The manual inspection or video monitoring is easy to cause slow response, inspection or monitoring blind spots, and can not find the belt breakage accident in time.
The utility model discloses utilize lever principle to touch, in time the stall after gravity hammer touching travel switch, the upside of pulley withstands the belt bottom surface, and when the upper belt was taken absolutely, the gravity hammer droops, touches travel switch to the holding state accomplishes in time the stall, prevents the accident enlargement, has reduced the accident rate, can effectively prevent the accident enlargement, and has strengthened the factor of safety of big belt operation.
The above description is only a preferred embodiment of the present invention, and should not be construed as limiting the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
