Description
Technical field
The utility model relates to a kind of travelling apron belt break protection device, the stall of particularly a kind of travelling apron cam pressure zone open type, belt break protection device.
Background technology
At present; the travelling apron belt break protection device of domestic use has: wedge press belt type and cam press belt type; be that the intelligence of utilizing sensor and micro controller system the to constitute controller that tests the speed detects the adhesive tape operation conditions; this fender guard is to install in two sides of adhesive tape to arrest device; arrest device (1-3) and arresting two end up and down that are positioned at two sides of adhesive tape; arrest device and be subjected to electromagnetic control apparatus (1-4) control; realize conveyer broken-belt; stall (hypervelocity) protection; the adhesive tape catching device that this device travelling apron is arranged is on the way kept strokes; reliably; but shortcoming is a fender guard to be installed on the adhesive tape; adhesive tape (1-1) run duration; when bulk materials (1-2) etc. passes through; arrest the easy material that hinders of head and pass through, cause material near arresting head, to stop up; pile up, make the band conveyor operation not smooth.
Summary of the invention
The purpose of this utility model be to provide a kind of as bulk materials by the time be difficult for causing material to stop up, pile up the stall of travelling apron cam pressure zone open type, belt break protection device.
The purpose of this utility model is achieved in that this device has pivot arm, rotates jib, arrests device, locating dowel pin, control link mechanism, first inhibiting device, second inhibiting device and electromagnetic control apparatus, be connected on the rotation jib other end and arrest device and be connected at pivot arm one end, side at the rotation jib is connected with locating dowel pin and electromagnetic control apparatus, opposite side at swivel mount is connected with the electromagnetic control apparatus and second inhibiting device, first inhibiting device is positioned at an end of control link mechanism, the other end of control link mechanism with arrest device and be connected.
Arrest device and be the wedge press belt type or be the cam press belt type.
There are limiting stopper, connecting rod, position-limited lever, back stop and pin and pinch roller in control link mechanism, and limiting stopper is connected in the rotation jib, and the other end that is positioned at an end link of connecting rod is connected with back stop and pin by position-limited lever, and back stop and pin are connected with pinch roller.
Beneficial effect: owing to adopt such scheme, arrest device and adopt wedge press belt type or cam press belt type belt break protection device, be installed in adhesive tape on one side, when conveyer normally moved, belt break protection device left travelling apron, did not influence various materials and passed through; When the controller that tests the speed detects adhesive tape broken belt, stall or hypervelocity, the action of electromagnetic control mechanism, outstanding pivoted arm is when rotating, belt break protection device is moved quickly on the adhesive tape, control link mechanism drives the belt break protection device action, arrest the adhesive tape of broken belt, stall, as bulk materials by the time be difficult for causing material to stop up, pile up; The inhibiting device actv. has prevented to arrest device and has crossed the position, locating dowel pin can prevent to arrest device bounce-back influence and arrest effect, control link mechanism can control and arrest device is arrested stall or hypervelocity in optimal position adhesive tape, as bulk materials by the time be difficult for causing material to stop up, pile up, reached the purpose of this utility model.
Advantage: the sensor of 1. cam pressure zone open type stall, belt break protection device is to utilize micro controller system to detect the adhesive tape operation conditions for the main intelligence that the constitutes controller that tests the speed; realization conveyer broken-belt, stall (hypervelocity) protection, this sensor precision height, reliable operation.
2. travelling apron cam pressure zone open type stall, belt break protection device design have outstanding pivoted arm, inhibiting device, locating dowel pin and control link mechanism etc.Inhibiting device guarantees the operating position of belt break protection device, and locating dowel pin is to drive the belt break protection device bounce-back when preventing the adhesive tape fluctuation, and effect is arrested in influence, and control link mechanism controls arresting agency arrives the adhesive tape of the accident of arresting behind the correct position.Inhibiting device, locating dowel pin and control link mechanism cooperatively interact, and guarantee that belt break protection device arrests effect tape, and actv. prevents adhesive tape to amplify the expansion of sliding and broken belt accident.
3. the sensor arranged on the way of conveyer all is associated in together, when any sensor to the adhesive tape operation exception, during as stall, broken belt backward, can control all belt break protection devices of arranging simultaneously on the way, arrest adhesive tape and keep strokes, reliably.Not influencing under the situation of arresting effect, can reduce the intensity of single catching device for this reason, reduce production costs, the minimizing expense.
4. the outstanding pivoted arm of the stall of travelling apron cam pressure zone open type, belt break protection device can to wide, the narrow load-transfer device that differs, have comformability preferably according to the on-the-spot actual design in down-hole.
5. this apparatus structure simplicity of design, reliable operation, easy to use can effectively prevent from the expansion or the solid accumulation of broken belt accident the broken belt accident to be controlled at the starting stage, reduce the broken belt settlement of accident time, and remarkable in economical benefits has popularizing application prospect preferably.
