Abstract
The utility model relates to a chain detecting signal device. The utility model is characterized in that a plurality of detectors are electrically supplied by a low-voltage power supply, wherein, each of the detectors is connected with a corresponding part to be detected, and the output end of each of the detectors is respectively connected with the signal output circuit thereof. The utility model can convert the working state (gas state or gasless state) of each link of a detected chain component and the position state (homing state or off normal state) of each component into signals which can be output respectively. The detectors of the utility model can be installed on site. The utility model has the advantages of convenient detection, simplicity, reliability, powerful anti-interference, reliable signals, easy acquirement, and wide range of adaptive temperature environment.
Description
The utility model is that a kind of airport pot type filling car and pipeline filling car of being applicable to detects the device of locking part mode of operation.
At present, the chain detection of pot type filling car both domestic and external or pipeline filling car is contained on the brake gas circuit, power takeoff work, platform are risen, the platform flexible pipe refuels to connect and chews and hose reel refuels to connect and action such as chews and all can cause the gas circuit pressure variation of braking, the variation of gas circuit can cause pressure relay work, reports to the police to cause the signal lamp indication; In addition, detect the playback of each parts and off normal, also be to adopt above-mentioned similar method, be referred to as chain indication and report to the police, because of this system has only a pressure relay, a signal lamp, it is simple in structure, but have the following disadvantages: when working because of filling car, link is many, all devotes oneself to work sometimes, and part is devoted oneself to work sometimes, and said system is as long as a link is out of order, signal lamp promptly shows, is which partly is out of order but can't inquire about actually, and is especially emergent in fault, situation when needing by " surmounting " switch, the people does not unload for separating except the control of brake air road, be prone to refuel to connect to chew, and flexible pipe is unrecovered, platform does not put down, but chain brakes off has promoted chain signal lamp and has gone out, and chaufeur is driven and caused the accident of drawing flying coffin and equipment.
The purpose of this utility model is to overcome above-mentioned weak point and provides a kind of can be the chain detection signal device of switching value signal output with the state exchange of each link of locking part.
The technical solution of the utility model is: the detector of n exportable switching value signal is powered by low potential source.Corresponding with each the respectively inspection parts that need of each detector input end join, and mouth links to each other with each signal output apparatus, to form chain detection signal device.Each detector is the corresponding state that needs the inspection parts of perception respectively, and is 0 or 1 switching value signal with these state exchanges, and the demonstration by this signal is the situation of corresponding device as can be known just.
Said detector can be pressure detector, is connected required detection position by quick coupling, experiences the pressure variation signal, and imports signal into pressure relay, the mode of operation of perception locking part.
Said detector also can be position detector, and position detector can be explosion-proof micro-switch, and explosion-proof micro-switch is installed on the position that each needs the inspection parts to touch, the location status of each link of perception locking part.
A said n detector, wherein n is greater than 1.
The utility model is with mode of operation (gaseity is arranged or do not have gaseity) and each position component state (playback state, the undocked state of each link of locking part; Normal operation, or emergent " surmounting " state of fault) be converted into signal, and output respectively, the utility model output can with the supporting use of chain detection telltale, show the state of locking part.Detector of the present utility model can be installed on the scene, and is easy to detect, simple and reliable, is output as the switching value signal, and disturbance rejection is strong, and signal is reliable, and is with low cost, obtains easily, and the adaptive temperature environmental field is wide.
Fig. 1 is embodiment 1 structural circuit figure of the present utility model;
Fig. 2 is the structural circuit figure of embodiment 2 of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Among the figure, 1 is platform pressurized strut gas circuit, 2 pressure detectors, 3 is the output signal circuit, 4 be platform flexible pipe gas circuit 1., 5 for platform flexible pipe gas circuit 2., 6 for reel flexible pipe gas circuit 1., 7 for reel flexible pipe gas circuit 2., 8 chew 1. for platform connects for lifting table, 12 for low potential source, 11 for bottom valve gas circuit, 10,13 chew 2., 14 chew 1., 15 chew 2. for reel connects for reel connects for platform connects for power takeoff gas circuit, 9.
Among Fig. 1, form chain pressure detecting signal device by gas circuit, pressure detector 2, output signal circuit 3.Its pressure detector is a baroswitch.Concentrate 7 baroswitches 2 that are contained in the box body, be parallel on the 12V low potential source, and power by low potential source.The mouth of baroswitch 2 is through 3 outputs of output signal circuit, platform pressurized strut gas circuit, platform flexible pipe gas circuit 1., platform flexible pipe gas circuit 2., reel flexible pipe gas circuit 1., reel flexible pipe gas circuit 2., power takeoff, bottom valve gas circuit are introduced corresponding baroswitch by φ 4 pressure guiding pipes respectively, after experiencing air pressure, by output signal circuit output 0 or 1 switching value signal.
Among Fig. 2,5 position detectors 2 are parallel to 12V low potential source 10, by low potential source 10 power supplies.Position detector 2 is explosion-proof micro-switch, and explosion-proof micro-switch 2 is through 3 outputs of output signal circuit.Explosion-proof micro-switch is contained in respectively that lifting table, platform connect and chew 1., platform connects and chews 2., reel connects and chews 1. reel and connect to chew and 2. wait the position that needs inspection contact object to touch, when the contact movement of objects, touch micro-switch, output signal circuit 3 is exportable 1 or 0 switching value signal, respectively contacts the position of object with reaction.
