Detailed Description

Specific embodiments of the device according to the utility model are described in further detail below with reference to the accompanying drawings.

The device for judging the faults of the periodically moving electric dragging trolley shown in the figures 1-3 comprises a base bracket 1, wherein the upper surface of the base bracket 1 is of an F-shaped structure, a baffle plate 3 is arranged at the upper end of the F-shaped structure of the base bracket 1, a firing pin 2 is arranged at the upper end of the baffle plate 3, the baffle plate 3 is rotatably arranged on the base bracket 1 through a rotating shaft 4, a photoelectric sensor 5 is arranged at the lower end of the F-shaped structure of the base bracket 1, and the photoelectric sensor 5 is used for periodically detecting the running condition of the periodically moving electric dragging trolley and converting a position signal into an electric signal to be sent into an electric control loop or an automatic control loop.

The utility model is composed of five parts, namely a base bracket 1, a firing pin 2, a baffle plate 3, a rotating shaft 4 and a photoelectric sensor 5, wherein the baffle plate and the firing pin are welded together, the base bracket 1 is effectively connected with the firing pin 2 and the baffle plate 3 through the rotating shaft 4 fixed on the baffle plate, the baffle plate 3 and the firing pin 2 are in a vertical state under the normal state of the device due to the gravity action of the baffle plate, when a trolley passes through, the mechanical part of the trolley contacts with the firing pin 2, so that the baffle plate 3 rotates along with the firing pin 2, and when the baffle plate 3 is separated from the photoelectric sensor 5, the photoelectric sensor 5 cannot detect the baffle plate 3, and the periodical circular operation equipment or the trolley which periodically reciprocates can pass through the position. When the trolley continues to walk far away, the mechanical part of the trolley is not contacted with the firing pin 3 of the device any more, the vertical state is kept under the gravity action of the baffle plate 2, the photoelectric sensor 5 detects the baffle plate signal again, the position signal is converted into an electric signal to be sent into an electric or automatic control loop, the on-off of an electric element is triggered through the mechanical device and the contact, so that the timing device of the trolley control system is controlled to reckon, and in the set time, the trolley which periodically operates the equipment circularly or periodically reciprocates is repeatedly contacted with the firing pin 3, so that the trolley is indicated to operate normally. Otherwise, judging that the trolley fails and stops running, and notifying related personnel to check and confirm equipment.

The detection device is used for triggering an electric signal to realize the protection of the motor in an electric and control system program by skillfully utilizing the original motor control loop, plays a role in protecting the trolley and warning, and solves the safety and technical problems that the fault expansion can not be found in time when the equipment is abnormal.

In the industrial control production field, the periodic round-trip operation trolley and the rotary operation trolley are widely applied, and in the actual operation process, the power source of the dragging motor cannot be stopped in time due to the abnormality of a speed reducing device, a trolley transmission device and the like and the untimely application of a monitoring device and a method and the like, so that huge loss and potential safety hazard are caused in many cases. The device is a combination of mechanical firmware and electrical components, when the trolley which moves periodically passes through a certain fixed point, the on-off of the electrical components is triggered through the mechanical device and contact, the trolley moves to the position again in a circulating way in a set period which is greater than the running period of the trolley, and the electrical components are triggered, so that the equipment is judged to run normally. If the mechanical device of the trolley does not touch the detection device in the set period, and the motor still runs, the condition that the trolley body stops running due to the mechanism faults such as the speed reducing device or the trolley transmission device is judged, the motor is dragged in a chained mode, and an alarm is given, so that the trolley and the alarm are protected.
