Abstract
The utility model relates to the field of an annular cooler, in particular to an apparatus for detecting the position of an annular cooler bogie, comprising a fixing rack, a supporting plate and a limit switch, wherein the supporting plate is fixedly mounted on the fixing rack, the limit switch is hinged with the supporting plate, and the detection rod of the limit switch is provided with a horizontal detection position and a vertical detection position. The apparatus for detecting the position of an annular cooler bogie can effectively detect the abnormal state of disengaging from mounting positions, of the wheels of the annular cooler bogie through using the limit switch to detect the positions of the wheels, in order to warn related personnel to timely adopt corresponding measures before causing a severe accident of overturning and locking the annular cooler bogie, thereby ensuring the fault of the annular cooler bogie to be timely processed, and furthest reducing the fault loss. In the process of real use, the apparatus for detecting the position of an annular cooler bogie shortens the maintenance downtime of a production line from 100 hours/year to 30 hours/year.
Description
SkillThe art field
The utility model relates to the central cooler field, relates in particular to a kind of circular cooler trolley pick-up unit.
Background technology
Central cooler is bend at the parts of equipment convey materials downstream, and when circular cooler trolley entered bend from horizontal rail, chassis can become upturned position by horizontal level along with the track of bend.If any single wheel of circular cooler trolley this moment breaks away from the chassis body, will cause chassis one side to break away from the bend track, cause chassis to tumble and be stuck in the space of bend and central cooler framework.Because the central cooler transverse width is 3.3 meters, weight is 10 tons, and the vertical height of bend and central cooler framework is less than 0.5 meter, in case chassis is tumbled and is stuck in the space of bend and central cooler framework, unique processing means are after the destructive axle with central cooler one side installing wheel cuts off, with hoisting machinery chassis is playbacked, erecting bed axletree locomotive wheel again, the general processing time is on average greater than 12 hours.Cause the sintering work line to shut down 12 hours, cause sintering output to lose more than 1,000,000 yuan.
In the prior art ring cold machine trolley wheel is departed from the detection of normal mounting position, usually adopting central cooler to skid to detect realizes, circular cooler trolley can cause central cooler to skid depart from normal run location in bend after, detection can avoid the central cooler ring cold machine trolley wheel to depart from the serious equipment failure of the central cooler that causes behind the normal mounting position by skidding, but this detection mode is for detect afterwards, can't prevent in advance circular cooler trolley to occur that the part wheel damages but substantial deviation not yet, can guarantee reluctantly the normal operation of central cooler but situation that circular cooler trolley need to overhaul.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of circular cooler trolley position detecting device, utilizes limit switch to detect the position of wheel, realizes the loosening wheel detection damaged of being about to, and prevents in advance the circular cooler trolley fault of tumbling.
The utility model is achieved in that a kind of circular cooler trolley position detecting device, comprise fixed mount, back up pad and limit switch, described back up pad is fixedly mounted on the fixed mount, described limit switch is hinged on the back up pad, and the test rod on the limit switch has horizontal detection position and vertical two detection positions of detecting position.
Described test rod is set with row's wear-resisting ring outward, and described wear-resisting ring is equidistantly evenly distributed.
Described wear-resisting ring is bakelite lasso, plastic ring or rubber ring.
The utility model circular cooler trolley position detecting device utilizes limit switch to detect the position of wheel, effectively detect the abnormality that detector for bogie wheels of circular cooler breaks away from the installation site, tumble before the jammed serious equipment breakdown not causing circular cooler trolley, remind the related personnel in time to take corresponding measure, guarantee that the fault of central cooler platform is in time processed, breakdown loss is reduced to minimum level; In actual the use, by the utility model the production line maintenance downtime is reduced to 30 hours from 100 hours stop times of year.The utility model can also be applied to the equipment that similar central cooler etc. adopts the track traveling and becomes closed loop.

Among the figure: 1 fixed mount, 2 back up pads, 3 limit switches, 4 test rods, 5 wear-resisting rings, 6 bogie wheels, 7 circular cooler trolleys.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model statement, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
As shown in Figure 1, 2, a kind of circular cooler trolley position detecting device, comprise fixed mount 1, back up pad 2 and limit switch 3, described back up pad 2 is fixedly mounted on the fixed mount 1, described limit switch 3 is hinged on the back up pad 2, and the test rod 4 on the limit switch 3 has horizontal detection position and vertical two detection positions of detecting position.
When test rod 4 is positioned at vertical detecting position, limit switch 3 is installed in the bogie wheels 6 both sides levels of circular cooler trolley 7, and test rod 4 is flexible test rod, when bogie wheels 6 runs to test rod 4 positions, test rod 4 is depressed, whether broken away from the normal mounting position to detect bogie wheels 6.
When test rod 4 is positioned at the horizontal detection position, for detection of the phenomenon that can occur inwardly survey or outside sideslip in the operational process of circular cooler trolley 7, with the test rod 4 of limit switch 3 and bogie wheels 6 not the check point during sideslip be arranged on the roughly detection point midway of test rod 4, again the action connection point signal of limit switch 3 is delivered in the PLC system, move interval time by calculating twice limit switch 3, whether break away from the normal mounting position to judge bogie wheels 6.
When bogie wheels 6 disengaging normal mounting position occurring, remind producers to take corresponding treatment measures.
In the utility model, because detecting spacing test rod 4 is flexure spring, be subject to ring cold machine trolley wheel 6 pressure and can cause mechanical wear, and the bogie wheels 6 average number of times that will touch test rod 4 every day have 1800 times more than, cause test rod generally to only have for 1 ~ February 4 serviceable lifes, can't satisfy the normal maintenance replacement cycle.For this reason, as shown in Figure 3, outside the test rod 4 of limit switch 3, be set with row's wear-resisting ring 5, described wear-resisting ring 5 is equidistantly evenly distributed, each wear-resisting ring 5 has certain width, width only otherwise impact detects and do not cause under the prerequisite that test rod 4 broken by backfin and gets final product, on has been installed the serviceable life that effectively raises limit switch 3 behind the wear-resisting ring 5, make bring up to 6 months serviceable life; In the present embodiment, described wear-resisting ring 5 uses bakelite lasso, plastic ring or rubber ring usually.
