[0023] The embodiment of the utility model will be described in further detail below in combination with the drawings and examples.

[0024] As shown in the accompanying Figure 1 to the accompanying Figure 6 :

[0025] Example 1: the utility model provides a support wheel wear plate of secondary use, including plate body assembly 1 and connecting assembly 2, plate body assembly 1 includes positioning seat 101 and wear plate 102, wear plate 102 is fixedly installed in the bottom of positioning seat 101 by countersunk bolt 3, and the bottom of wear plate 102 is in contact on the support wheel, connecting assembly 2 includes fixed connecting seat 201 and distance sensor 202, and fixed connecting seat 201 is fixedly installed in the bottom of the fixed base in the transmission structure of the grate of the incinerator, positioning seat 101 is inserted in the bottom of fixed connecting seat 201, and distance sensor 202 is fixedly installed in the inside of fixed connecting seat 201.

[0026] Distance sensor 202 is electrically connected with external power supply and control device, and its specific structure and working principle are existing mature technology, which will not be repeated here.

[0027] In the embodiment of the present disclosure, the bolt hole of the top and bottom of wear plate 102 is provided with countersunk recess 1021, and the top and bottom of wear plate 102 are provided with countersunk recess 1021, so that when the contact surface of wear plate 102 is worn with guide wheel, wear plate 102 can be used again by turning over, and the countersunk recess 1021 arranged on both sides makes wear plate 102 always in flat state no matter how it is installed, which can realize rolling friction between wear plate 102 and support wheel stably, improve the utilization rate of wear plate 102 and has high flexibility.

[0028] In the embodiment of the present disclosure, the top of the positioning seat 101 is provided with a track block 1011 with a "T" shaped cross section, and the bottom of the fixed connecting seat 201 is provided with a track groove 2011, the track block 1011 is inserted into the inside of the track groove 2011, and the length of the track groove 2011 is slightly greater than the length of the block of the track block 1011. This design limits the moving track and maximum moving limit of the positioning seat 101 at the bottom of the fixed connecting seat 201, and the use is stable.

[0029] In the embodiment of the present disclosure, the distance sensor 202 can monitor the distance change between itself and the track block 1011, the side surface of the track block 1011 is provided with a limiting top spring 1012, and the two ends of the limiting top spring 1012 are respectively abutted against the inside of the track block 1011 and the inside of the fixed connecting seat 201. The acting force of the limiting top spring 1012 on the track block 1011 is greater than the rolling friction between the supporting wheel and the wear-resistant plate 102, and the acting force of the limiting top spring 1012 on the track block 1011 is less than the sliding friction between the supporting wheel and the wear-resistant plate 102. In use, the wear degree between the wear-resistant plate 102 and the supporting wheel can be monitored through the connecting assembly 2. Since the acting force of the limiting top spring 1012 on the track block 1011 is greater than the rolling friction between the supporting wheel and the wear-resistant plate 102 and less than the sliding friction between the supporting wheel and the wear-resistant plate 102, the rolling friction between the supporting wheel and the wear-resistant plate 102 is rolling friction in normal use. When the supporting wheel moves towards the direction of the limiting top spring 1012, the rolling friction is not enough to make the limiting top spring 1012 appear compression phenomenon through the plate body assembly 1, that is, the plate body assembly 1 does not change the use position under the action of the limiting top spring 1012 when the supporting wheel moves towards the direction of the limiting top spring 1012 in rolling friction, so the distance (interval) between the track block 1011 and the distance sensor 202 does not change. This means that the wear-resistant plate 102 and the supporting wheel are in a normal rolling friction state. With the increase of use time, when the supporting wheel is worn to a certain degree, sliding friction will occur between the contact surface of the supporting wheel and the wear-resistant plate 102. At this time, the sliding friction is greater than the elastic force of the limiting top spring 1012. Therefore, when the supporting wheel moves towards the direction of the limiting top spring 1012 thereafter, the sliding friction will make the limiting top spring 1012 appear compression phenomenon through the plate body assembly 1, that is, the plate body assembly 1 will change the use position under the action of the limiting top spring 1012 when the supporting wheel moves towards the direction of the limiting top spring 1012 in sliding friction. Therefore, the distance (interval) between the track block 1011 and the distance sensor 202 will change. After the distance sensor 202 monitors this information, it will send it to the control device and alarm, reminding the staff that sliding friction occurs between the supporting wheel and the wear-resistant plate 102, that is, the supporting wheel and the wear-resistant plate 102 need to be repaired or replaced, to ensure the normal operation of the device and the convenient and flexible use.

[0030] The specific use and effect of the embodiment are:

[0031] In the utility model, the wear degree between the wear plate 102 and the supporting wheel can be monitored through the connecting assembly 2, the acting force of the limiting top spring 1012 on the track block 1011 is greater than the rolling friction between the supporting wheel and the wear plate 102 and is less than the sliding friction between the supporting wheel and the wear plate 102, so that the rolling friction between the supporting wheel and the wear plate 102 is in a normal state when being used normally, when the supporting wheel moves towards the limiting top spring 1012, the rolling friction is insufficient to make the limiting top spring 1012 appear compression phenomenon through the plate body assembly 1, that is, the plate body assembly 1 does not change the use position under the action of the limiting top spring 1012, so that the distance (interval) between the track block 1011 and the distance sensor 202 does not change, which shows that the wear plate 102 and the supporting wheel are in a normal rolling friction state, with the increase of the use time, when the supporting wheel is worn to a certain degree, the sliding friction between the contact surface of the wear plate 102 and the supporting wheel is generated, at this time, the sliding friction is greater than the elastic force of the limiting top spring 1012, so that when the supporting wheel moves towards the limiting top spring 1012, the sliding friction can make the limiting top spring 1012 appear compression phenomenon through the plate body assembly 1, that is, the plate body assembly 1 changes the use position under the action of the limiting top spring 1012 when the sliding friction is generated, so that the distance (interval) between the track block 1011 and the distance sensor 202 changes, the distance sensor 202 sends the information to the control device and alarms after monitoring the information, reminding the staff that the sliding friction between the supporting wheel and the wear plate 102 is generated, that is, the supporting wheel and the wear plate 102 need to be repaired or replaced, so as to guarantee the normal operation of the device, the top surface and the bottom surface of the wear plate 102 are provided with the countersunk recess 1021, so that when the contact surface of the wear plate 102 is worn with the guide wheel, the wear plate 102 can be used again by turning over, the countersunk recess 1021 arranged on the two surfaces makes the working surface of the wear plate 102 always in a flat state, so that the rolling friction between the wear plate 102 and the supporting wheel can be realized stably, and the utilization rate of the wear plate 102 is improved.
