Abstract
The utility model discloses a detection and protection device of a safety shield of a stranding machine. The detection and protection device of the safety shield of the stranding machine is simple in structure, high in reliability and convenient to maintain. According to the detection and protection device of the safety shield of the stranding machine, a transmitter of a photoelectric correlation switch is installed at one end of the top of the safety shield of the stranding machine, a receiver of the photoelectric correlation switch is installed at the other end of the top of the safety shield of the stranding machine, the transmitter of the photoelectric correlation switch and the receiver of the photoelectric correlation switch are located on the same horizontal line, a signal output end of the receiver of the photoelectric correlation switch is connected with a coil of a crystal relay, a pair of normally-closed auxiliary contacts of the crystal relay is connected to a control circuit of equipment in series, the control circuit of the equipment is controlled to be cut off through the breakover of the normally-closed auxiliary contacts of the crystal relay, and then the equipment is controlled to stop. According to the detection and protection device of the safety shield of the stranding machine, the photoelectric correlation switch and the crystal relay are combined to detect the safety shield and control the equipment to stop, the reliability is high, the structure is simple, the detection distance is long, the device is not influenced by vibration of the safety shied of a vehicle body, and repairing and maintenance are convenient, and maintenance cost is low.
Description
Technical field
The utility model relates to a kind of strander safety guard and detects protective device.
Background technology
In the steel wire rope process, need to use strander to twist with the fingers thigh.For support equipment and personnel's safety, 18 safety guards are installed on strander, need 18 safety guard Close Alls in twisting with the fingers burst process.
In order to detect whether Close All of safety guard, at the window place of each safety guard, approach switch is installed, 18 approach switchs are to connect with series system.Because the detection of approach switch distance only has 5mm, only have that approach switch just can work when safety guard is fully closed.Simultaneously, because approach switch is connected in series, in case there is an approach switch to break down, a whole set of protective device is with actual effect, and maintenance maintenance is loaded down with trivial details, maintenance time is long, maintenance cost is high, very likely causes probe to damage when car body generation fracture of wire.In addition, because the car body safety guard can vibrate in running, as long as there is the closed bad car of a safety guard to stop, what impact was produced normally carries out.
The utility model content
The purpose of this utility model is for the technological deficiency that exists in prior art, and provides a kind of simple in structure, and reliability is high, and strander safety guard easy to maintenance detects protective device.
For realizing that the technical scheme that the purpose of this utility model adopts is:
a kind of strander safety guard detects protective device, comprise photoelectricity correlation switch, Switching Power Supply, the crystal relay, the transmitter of described photoelectricity correlation switch is installed on strander safety guard top one end, the receiver of described photoelectricity correlation switch is installed on the other end at strander safety guard top, the transmitter of described photoelectricity correlation switch and receiver are in the same horizontal line, the signal output part of described photoelectricity correlation switch receiver is connected with the coil of described crystal relay, the a pair of normally closed auxiliary contact of described crystal relay is serially connected in the equipment control loop, the cut-out of the conducting control appliance control loop by described crystal relay normally closed auxiliary contact, thereby the shutdown of control appliance, the input of described Switching Power Supply is connected with external power supply by breaker, and the output of described Switching Power Supply is connected with described photoelectricity correlation switch, is described photoelectricity correlation switch power supply.
Compared with prior art, the beneficial effects of the utility model are:
1, strander safety guard of the present utility model detects protective device and adopts photoelectricity correlation switch and crystal relay assembly to realize the detection of safety guard and the control of equipment downtime, because transmitter and the receiver of photoelectricity correlation switch is arranged on the same level straight line, and, a strander device just wants a pair of photoelectricity correlation switch just passable, reliability is high, as long as there is a safety guard there is no closure, light source will be blocked, thereby make the receiver of photoelectricity correlation switch can't receive light, crystal relay cutting-off controlling loop, make equipment downtime, thereby play the effect to personnel and equipment protection.
2, it is simple in structure that safety guard of the present utility model detects protective device, detects distance, is not subjected to car body safety guard vibration effect, maintenance, easy to maintenance, and maintenance cost is low.
Description of drawings
Figure 1 shows that the utility model strander safety guard detects the circuit theory diagrams of protective device.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
the circuit theory diagrams of the utility model strander safety guard detection protective device as shown in Figure 1, comprise photoelectricity correlation switch, Switching Power Supply, the crystal relay, the transmitter of described photoelectricity correlation switch is installed on strander safety guard top one end, the receiver of described photoelectricity correlation switch is installed on the other end at strander safety guard top, the transmitter of described photoelectricity correlation switch and receiver are in the same horizontal line, the signal output part of described photoelectricity correlation switch receiver is connected with the coil of described crystal relay, the a pair of normally closed auxiliary contact of described crystal relay is serially connected in the equipment control loop, the cut-out of the conducting control appliance control loop by described crystal relay normally closed auxiliary contact, thereby the shutdown of control appliance, the input of described Switching Power Supply is connected with external power supply by breaker, and the output of described Switching Power Supply is connected with described photoelectricity correlation switch, is described photoelectricity correlation switch power supply.
When safety guard all closes when complete, the light that the transmitter of photoelectricity correlation switch is launched will be received by the receiver of photoelectricity correlation switch, thereby exports a low level signal, and the normally closed auxiliary contact of crystal relay is in closure state, and equipment can normally start.
When there being a safety guard there is no closure; the light that the transmitter of photoelectricity correlation switch is launched just can not received by the receiver of photoelectricity correlation switch; it is electric that signal end output one high level signal of photoelectricity correlation switch gets the crystal relay; the normally closed auxiliary contact cutting-off controlling loop of crystal relay; make equipment downtime, thereby play the effect to personnel and equipment protection.
The above is only preferred embodiment of the present utility model; should be noted that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
