DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-5 As shown, the utility model provides a technical solution: a detection device for a sintering machine trolley, comprising a base 1, two symmetrically distributed tracks 2 are fixedly installed on the top of the base 1, a plurality of evenly distributed wheels 3 are arranged on the two tracks 2, a same vehicle body 4 is rotatably installed on one side where the plurality of wheels 3 are close to each other, a telescopic slot 5 is opened on the base 1 and located in front of the front track 2, a telescopic detection component is arranged in the telescopic slot 5.

[0027] In this embodiment, the telescopic detection component includes a slider 6, a spring 7 and a telescopic block 8. The slider 6 is slidably mounted at the bottom of the telescopic slot 5, the spring 7 is fixedly mounted on the top of the slider 6, the telescopic block 8 is fixedly mounted on the top of the spring 7 and slidably mounted in the telescopic slot 5, the spring 7 can push the telescopic block 8 to move upward to conflict with the wheel 3, and the telescopic block 8 drives the limit block 10 to conflict with the touch switch 11, the top of the telescopic block 8 extends outside the telescopic slot 5 and conflicts with the corresponding wheel 3, the top of the telescopic block 8 is a smooth arc structure, by utilizing the smooth arc structure at the top of the telescopic block 8, it can be convenient to conflict with the wheel 3, and be crushed back into the telescopic slot 5 by the wheel 3, the telescopic detection component also includes two limit blocks 10 and a touch switch 11, the left and right sides of the telescopic slot 5 are provided with limit slots 9, the left and right sides of the telescopic block 8 are fixedly installed with limit blocks 10, the two limit blocks 10 are respectively slidably mounted in the two limit slots 9, and the touch switch 11 is fixedly mounted on the top inner wall of one of the limit slots 9.

[0028] In this embodiment, a microprocessor 12, a timer 13, an audible and visual alarm 14 and a switch 15 are fixedly installed on the front side of the base 1, and the microprocessor 12, the timer 13, the audible and visual alarm 14, the switch 15 and the touch switch 11 are electrically connected via wires.

[0029] In this embodiment, an inspection groove 16 is provided on the front side of the telescopic groove 5, and a slide groove 17 is provided on the bottom of the telescopic groove 5. The bottom inner wall of the slide groove 17 is flush with the bottom inner wall of the inspection groove 16, and the slider 6 is slidably installed in the slide groove 17. The front sides of the two limit grooves 9 are connected to the inspection groove 16, and a positioning block 18 is slidably installed in the inspection groove 16. The positioning block 18 can be used to position the telescopic block 8, the spring 7 and the slider 6 to prevent the telescopic block 8 from shifting. The top of the positioning block 18 extends to the outside of the inspection groove 16 and is fixedly installed with a lifting block 19. The lifting block 19 can be used to easily remove the positioning block 18, and then the telescopic block 8, the spring 7 and the slider 6 can be taken out for maintenance and replacement.

[0030] Through the above structure, the detection device for a sintering machine trolley provided by the utility model can ignore the influence of dust, and use multiple wheels 3 passing at a uniform speed to squeeze the telescopic block 8 in turn. The squeezing movement process is not disturbed by dust, which improves the detection accuracy and the applicable scope of the detection scene. When a wheel 3 falls off, the contact time between the limit block 10 and the touch switch 11 is greater than the normal value under the push of the spring 7, and the microprocessor 12 controls the sound and light alarm 14 to run, reminding the operator that the wheel has fallen off, and timely checking and confirming to avoid the occurrence of production accidents. The positioning block 18 can also be used to constrain the positioning of the telescopic block 8 to avoid the telescopic block 8 When the telescopic detection assembly is in use, a sintering machine trolley to be detected is pulled from the right side of the telescopic detection assembly to the left at a constant speed. When the first wheel on the left side of the sintering machine trolley contacts the top of the telescopic block 8, the telescopic block 8 is gradually compressed downward. At the same time, the telescopic block 8 compresses the spring 7 downward. The two limit blocks 10 are also driven by the telescopic block 8 to move away from the touch switch 11, triggering the microprocessor 12 and the timer 13 to start running. When the first wheel 3 is separated from the telescopic block 8, the spring 7 pushes the telescopic block 8 to move upward and return to the initial position. At the same time, the two limit blocks 10 also return to the initial position, and one of the limit blocks 10 contacts the touch switch 11. At this time, the timer 13 starts to count the contact time separately. Since the sintering machine trolley moves at a constant speed from right to left, after each wheel 3 squeezes and separates from the telescopic block 8, the time that the limit block 10 contacts the touch switch 11 is a fixed value with an error range of ±0.1 seconds. When a wheel falls off, after the previous wheel 3 leaves the telescopic block 8, the limit block 10 contacts the touch switch 11 until the next wheel 3 squeezes the telescopic block 8, causing the limit block 10 to separate from the touch switch 11. The contact time is about twice the normal fixed time. The timer 13 transmits the data to the microprocessor 12 for processing. After the microprocessor 12 calculates and determines that the wheel has fallen off abnormally, the microprocessor 12 controls the sound and light alarm 14 to operate, reminding the operator of the wheel falling off, and timely checking and confirming to avoid the occurrence of production accidents. It is not affected by a large amount of floating dust in the on-site working environment, and the detection accuracy and the applicable scope of the detection scene are improved. When it is necessary to inspect and replace parts of the telescopic detection assembly, the positioning block 18 is taken out by the lifting block 19, and the telescopic detection assembly can be controlled to move forward and taken out from the inspection slot 16. It is simple and convenient, and greatly improves the maintenance efficiency.

[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
