Referring to fig. 1-5, the utility model relates to a track type trolley wheel drop detection device, which comprises a first detection crank arm 2, a second detection crank arm 5 and a control module 4. The first detection crank arm 2 and the second detection crank arm 5 are respectively arranged on one sides of the two rails 3, and the first detection crank arm 2 and the second detection crank arm 5 are symmetrically arranged. One ends of the first detection crank arm 2 and the second detection crank arm 5 extend into the corresponding path of the running path of the wheel 1, a rectangular contact piece is arranged at one end of the rail, and when the wheel 1 runs on the rail 3 in the running process of the trolley, the upper end of the rectangular contact piece can be pressed downwards.
The other end below of the first detection crank arm 2 is provided with a first proximity switch S1, the other end below of the second detection crank arm 5 is provided with a second proximity switch S2, and the output ends of the first proximity switch S1 and the second proximity switch S2 are respectively connected with two signal acquisition ends of the control module 4 in a one-to-one correspondence mode.
One end of the first proximity switch S1 is connected with the live wire, the other end of the first proximity switch S1 is connected with the zero line through a coil K1 of the relay, and a first signal acquisition end of the control module 4 is electrically connected with an external power supply through a normally open contact of the relay K1.
One end of the second proximity switch S2 is connected with the live wire, the other end of the first proximity switch S2 is connected with the zero line through a second K2 coil of the relay, and a second signal acquisition end of the control module 4 is electrically connected with an external power supply through a normally open contact of the second K2 coil of the relay.
The circuit that live wire and zero line are connected is equipped with a circuit protection device Q1, and circuit protection device Q1 can be for earth leakage protector, can prevent live wire and zero line misconnection, and when earth leakage current exceeded the setting value, the protector can automatic cutout power, protection personal safety.
The external power supply is connected with the normally open contact of the relay through a protection switch Q2, and the protection switch Q2 is used for protecting the control module 4.
The control module 4 is a programmable logic controller and is responsible for receiving the electric signals so as to further judge whether the wheels on two sides have faults.
The first proximity switch S1 is fixedly arranged on the ground of the mounting rail 3 through a first mounting seat 6, a plurality of first tension springs are fixedly arranged in the first mounting seat 6, and the tail ends of the first tension springs are fixedly connected with the first detection crank arms 2.
The second proximity switch S2 is fixedly arranged on the ground of the mounting rail 3 through a second mounting seat 7, a plurality of second tension springs are fixedly arranged in the second mounting seat 7, the tail ends of the second tension springs are fixedly connected with the second detection crank arms 5, and the action of the tension springs is to enable the proximity switch to reset after being closed.
In this embodiment, the technical means for determining whether the wheel is faulty or not according to the electrical signal received by the PLC belongs to a technical means commonly used in PLC technology development, and is common knowledge, and this embodiment does not improve the technical means.
The working principle of the utility model is as follows: for the power-on of the detection device, the track-type trolley runs on the rail 3, and when the wheels 1 of the track-type trolley run on the detection device, if the wheels on two sides of the track-type trolley are not in a falling fault, the wheels 1 on two sides of the track-type trolley respectively press the rectangular contact piece at one end of the first detection rod 2 and the rectangular contact piece at one end of the second detection rod 5 downwards. Because the hinged installation of the detection crank arm, the other end of the detection crank arm is lifted upwards to be far away from the proximity switch, so that the switch state of the proximity switch is in an off state. The two relays are in a non-working state, and the input signals of the two signal acquisition ends of the control module 4 are low level. Because the level of the two signal acquisition ends is the same low level, the control module 4 can judge that the current two wheels 1 of the track type trolley are in a fault-free state.
When two wheels 1 of the track-type trolley upward-path detecting device are in a falling-off state, one wheel 1 and the other wheel 1 work normally. If the wheel 1 on the side of the track-type trolley, which is close to the first proximity switch S1, does not fall off, the first proximity switch S1 of the first detection crank arm 2 is in an off state under the extrusion action of the wheel 1, so that the relay one K1 is in an off state, and the input signal of the first signal acquisition end of the control module 4 is at a low level. But the input signal of the second signal acquisition end of the control module 4 is high level, and the levels of the two signal acquisition ends are inconsistent, so that the control module 4 can judge that the wheel 1 of the track trolley on one side of the second detection crank arm 5 breaks down, and the control module 4 starts to flash and sounds from a second wheel alarm lamp.
While only the preferred embodiments of the present utility model have been described above, it should be noted that modifications and improvements can be made by those skilled in the art without departing from the structure of the present utility model, and these do not affect the effect of the implementation of the present utility model and the utility of the patent.
