The utility model has the following beneficial effects:

1. through the alarm function of the utility model, the trolley wheel can alarm for the first time when the trolley wheel is blocked by a fault, and post personnel can rapidly process the trolley wheel to ensure stable production operation.

2. By utilizing the characteristic of constant-speed operation of the sintering trolley, the real-time monitoring of the sintering trolley is realized by touching the limit switch at regular time through the detection rod, and the aim of monitoring the full working time is fulfilled.

3. By utilizing the characteristic that the sintering trolley stays after being blocked, the blocking of the sintering trolley is judged by a mode that the detection rod contacts with the limit switch for a long time or the detection rod does not contact with the limit switch for a long time, then an audible and visual alarm is used for alarming from vision and hearing, and post personnel is informed in the shortest time, so that the function of blocking and alarming is realized.

4. The utility model has the advantages of simple structure, convenient manufacture, low cost and strong practicability.

Detailed Description

The utility model will now be described in further detail with reference to the accompanying drawings.

As shown in fig. 1-2, a self-checking alarm device for wheel clamping and stopping of a sintering pallet comprises a bottom plate 1, a rotating shaft 2 is welded at the middle position of the bottom plate 1, a detection rod 3 and a pressing ring 4 are sequentially sleeved on the rotating shaft 2, a through hole 5 is formed in the top end of the rotating shaft 2, a pin 6 is connected in the through hole 5 in a penetrating manner, a limit switch 7 is installed at the position of one side of the bottom of the detection rod 3 on the bottom plate 1, an audible and visual alarm 8 is installed on the bottom plate 1 above the limit switch 7, a stop lever 9 is welded at one side, close to the audible and visual alarm 8, of the top of the bottom plate 1, a support 10 is welded at the back of the bottom plate 1, and the limit switch 7 is electrically connected with the audible and visual alarm 8. The position of the rotating shaft 2 close to the bottom plate 1 is provided with a clamping table 11 for clamping the detection rod 3. The middle position of the detection rod 3 is provided with a lantern ring 12, and the detection rod 3 is sleeved with the rotating shaft 2 through the lantern ring 12. The limit switch 7 is obliquely installed, and is used for touching the limit switch 7 in front when the detection rod 3 rotates by taking the rotating shaft 2 as the shaft. When the detecting rod 3 rotates around the rotating shaft 2 at intervals and touches the limit switch 7, the audible and visual alarm 8 is not triggered to alarm. When the detection rod 3 touches the limit switch 7 for a long time or does not touch the limit switch 7 for a long time, the audible and visual alarm 8 triggers an alarm.

The working principle of the utility model is as follows: as shown in fig. 3, when in use, the bracket 10 of the device is welded on the annular cooler body 14 at the bottom of the lane rail 15 of the sintering platform, and the wheels 13 of the sintering platform touch the detection rod 3 at intervals when in operation, so that the detection rod 3 rotates by taking the rotating shaft 2 as an axis, the bottom of the detection rod 3 touches the limit switch 7 at intervals of the same time, no alarm is triggered at the moment, and when the wheels 13 are blocked, the wheels possibly touch the detection rod 3 just, and at the moment, the bottom of the detection rod 3 touches the limit switch 7 for a long time to trigger the alarm; the wheel 13 may not touch the detecting rod 3 at all when being blocked, or the detecting rod 3 does not touch the limit switch 7 although touching the detecting rod 3, and the limit switch 7 is not touched for a long time to trigger an alarm. The long time is set to be longer than the time interval of the detection rod 3 touching the limit switch 7 during normal operation, and the alarm can be triggered within a few seconds after the wheel 13 is stopped due to the shorter time interval.
