Belt conveyor for preventing broken belt catches only device
Technical field
The present invention relates to the anti-belt break protection device that a kind of belt transporter uses.
Background technology
At present, China's coal-mine, power plant, chemical industry, the large enterprises such as port and pier equipment of conveyer used, often there is broken belt accident, especially in coal production, for meeting high yield, the needs of efficient coal production, belt transporter is just towards long distance, high-power, large conveying quantity, high belt speed future development, because belt is in long-time high loaded process always, add interference and the impact of external factor, it is tired aborning easily to there is belt connector in coal conveyor belt, or run into obstacle jam belt, the unexpected fracture of belt is caused in capital, especially large for inclination angle, adhesive tape is long, the upper fortune belt transporter that load is large, once there is broken belt and belt reverse accident, belt frame will be destroyed, damage equipment, blocking belt heading, cause and stop production for a long time and heavy economic losses, even personal casualty, consequence is extremely serious.And the belt break protection device of traditional high spud angle coal conveyor belt, power of arresting is limited, and Reliability of Microprocessor is poor.
Summary of the invention
The deficiency of the present invention in order to solve the problem, provides a kind of structure simple, and the belt conveyor for preventing broken belt that reliability is high catches only device, and usage range is wide, can adapt to the coal conveyor belt of various different angle degree.
Technical scheme of the present invention is: belt conveyor for preventing broken belt is caught and stopped device by up belt capture device, and descending belt capture device is formed.
Up belt capture device is installed on belt feeder top, and inside is provided with forward catching device clamp.
Travelling belt passes through by forward catching device clamp bayonet socket, belt upwards normal rotation time clamp open, belt normal operation can not be affected, when there is broken belt accident, landing belt friction clamp, make clamp clamp rapidly, thus arrest the up belt of disconnection.
Descending belt capture device is installed on belt feeder bottom, inner installation catching device clamp, broken belt inductor.
Catching device clamp are connected with broken belt inductor, broken belt inductor is made up of infrared transmitting device and infrared ray light-receiving device, infrared transmitting device and infrared ray light-receiving device symmetry are installed, and when belt disconnects, infrared ray light-receiving device receives signal, and catching device clamp are closed only catches disconnection belt.
Useful good effect of the present invention is: adopt Dual-layer break catching apparatus, arrest better effects if, safety factor is higher.
Accompanying drawing illustrates:
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is that belt conveyor for preventing broken belt catches only device integral structure schematic diagram;
Fig. 2 is forward catching device clamp structural representations.
Fig. 3 is descending belt capture device structural representation.
Detailed description of the invention:
1 belt feeder in the drawings, 1.1 travelling belts, 2 up belt capture device, 2.1 forward catching device clamp, 2.11 clamp bayonet sockets, 3 descending belt capture device, 3.1 catching device clamp, 3.2 broken belt inductors, 3.21 infrared transmitting devices, 3.22 infrared ray light-receiving devices.
Embodiment 1
Belt conveyor for preventing broken belt is caught and is stopped device by up belt capture device 2 as shown in the figure, and descending belt capture device 3 is formed.
Up belt capture device 2 is installed on belt feeder 1 top, inside is provided with forward catching device clamp 2.1, travelling belt 1.1 passes through by forward catching device 2.1 clamp bayonet socket 2.11, belt upwards normal rotation time clamp open, belt normal operation can not be affected, when there is broken belt accident, landing belt friction clamp, clamp are clamped rapidly, thus the up belt of disconnection is arrested.
Descending belt capture device 3 is installed on belt feeder 1 bottom, inner installation catching device clamp 3.1, broken belt inductor 3.2, catching device clamp 3.1 are connected with broken belt inductor 3.2, broken belt inductor 3.2 is made up of infrared transmitting device 3.21 and infrared ray light-receiving device 3.22, and infrared transmitting device 3.21 is installed with infrared ray light-receiving device 3.22 symmetry, and when belt disconnects, infrared ray light-receiving device 3.22 receives signal, catching device clamp 3.1 are closed only catches by disconnection belt, the generation of Accident prevention.
