Technical Field
[0001] This utility model relates to the field of cutting tooth wear detection technology, specifically a cutting tooth wear condition detection device. Background Technology
[0002] Cutting teeth are installed on components such as the drum of a coal mining machine and the cutting head of a tunneling machine. They come into direct contact with the coal and rock being mined and cut and crush the coal and rock through rotation or reciprocating motion. They are an important tool for achieving efficient mining operations.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-6 The present invention provides the following technical solution:
[0028] A cutting tooth wear condition detection device includes a connecting device 1 and a detection housing 5. A chassis body 3 is installed on the rear end of the inner wall surface of the detection housing 5. LED panels 2 are bolted to the left and right sides of the chassis body 3. A laser sensor 4 is bolted to the front end of the chassis body 3. The connecting device 1 is bolted to the front of the detection housing 5.
[0029] The connecting device 1 includes a connecting plate body 11, a cutting tooth body 12 inserted into the inner wall surface of the connecting plate body 11, a fastening bolt 15 threadedly connected to the edge of the connecting plate body 11, a plug-in housing 14 connected to the front end surface of the connecting plate body 11, and the fastening bolt 15 bolted to the front and rear ends of the plug-in housing 14. The fastening bolt 15 locks and fixes the plug-in housing 14, the connecting plate body 11 and the connecting base 138, and determines the position of the connecting plate body 11 and the cutting tooth body 12, so as to facilitate the disassembly and replacement of the connecting plate body 11. A limit component 13 is connected to the front side of the cutting tooth body 12.
[0030] The limiting component 13 includes a metal frame 131. A connecting block 134 is bolted to the middle position of the metal frame 131. A clamping frame 133 is slidably connected to the inner wall surface of the connecting block 134. The connecting blocks 134 are located in two sets, and the two sets of connecting blocks 134 are distributed at the upper and lower ends of the metal frame 131. Each set of connecting blocks 134 has four blocks. The four connecting blocks 134 in the same set are distributed at the top of the metal frame 131. The two sets of connecting blocks 134 determine the position of the clamping frame 133, which facilitates the disassembly and replacement of the clamping frame 133.
[0031] A limiting block 135 is inserted into the outward end of the clamping frame 133, and the inward end of the limiting block 135 is movably connected to the rotating disk 136. The limiting block 135 is inserted into the middle position of the connecting block 134 and into the upper and lower ends of the metal frame 131. The limiting block 135 limits and fixes the metal frame 131, the clamping frame 133 and the connecting block 134, making it convenient to disassemble and replace the clamping frame 133.
[0032] A connecting rod 137 is welded to the middle position of the rotating disk 136. The connecting rod 137 is inserted into the front end of the detection housing 5. The detection housing 5 determines the position of the connecting rod 137, which facilitates the disassembly and replacement of the rotating disk 136 and the connecting rod 137, thereby facilitating the disassembly and replacement of the connecting disk body 11, the connecting base 138 and the cutting tooth body 12.
[0033] A connecting base 138 is welded to the back of the connecting rod 137. The plug-in housing 14 is movably connected to the rear end of the connecting base 138. The fastening bolt 15 is threadedly connected to the rear end of the connecting base 138. The fastening bolt 15 locks and fixes the plug-in housing 14 and the connecting base 138. The fastening bolt 15 locks and fixes the connecting base 138, the connecting disc body 11 and the plug-in housing 14, thereby determining the position of the cutting tooth body 12.
[0034] Metal ears 132 are bolted to the surface of the metal frame 131. The metal ears 132 are bolted to the front of the detection housing 5. The metal frame 131 is movably connected to the front of the detection housing 5. The bolts lock and fix the connecting block 134, the metal frame 131 and the detection housing 5, making it convenient to disassemble and replace the metal frame 131 and the metal ears 132.
[0035] When in use, pull the limiting plug 135 forward to disengage the limiting plug 135 from the connecting block 134, the metal frame 131 and the clamping frame 133, and loosen the connection between the metal frame 131 and the clamping frame 133.
[0036] Push the clamping frame 133 upward to disengage it from the rotating disk 136. Then pull the connecting rod 137. The connecting rod 137 drives the rotating disk 136, the connecting base 138 and the cutting tooth body 12 to one end outward, making it easy to disassemble and replace the cutting tooth body 12.
[0037] When the fastening bolt 15 is rotated, it disengages from the connecting base 138, the plug-in housing 14, and the connecting plate body 11, causing the connection between the plug-in housing 14, the connecting base 138, and the connecting plate body 11 to loosen.
[0038] Pull the plug-in housing 14 outward to detach it from the connecting plate body 11 and the connecting base 138. The connecting plate body 11 and the cutting tooth body 12 detach from the connecting base 138. Then pull the cutting tooth body 12 forward to disassemble it, making it easier to perform wear detection on the cutting tooth body 12.
[0039] The replaced cutting tooth body 12 and connecting plate body 11 are connected to the connecting base 138 through the plug-in housing 14 and connecting plate body 11 to determine the position of the cutting tooth body 12 and connecting plate body 11. Then the connecting rod 137 and connecting base 138 are inserted into the front end of the detection housing 5.
[0040] Then, the clamping frame 133 is inserted into the edge of the rotating disk 136, and the limiting block 135 is inserted to determine the position between the clamping frame 133 and the metal frame 131, thereby determining the position of the rotating disk 136.
[0041] Rotate the rotating disk 136. The rotating disk 136 drives the connecting base 138 to rotate the connecting disk body 11 through the connecting rod 137. The connecting disk body 11 drives the cutting tooth body 12 to rotate, so that the cutting tooth body 12 rotates inside the detection housing 5.
[0042] LED panel 2 activates the laser sensor 4 at the front of the chassis 3. The laser emitter illuminates the surfaces of the cutting teeth and the connecting plate body 11. The deviation of the projection contour lines of the light source on the surfaces of the connecting plate body 11 and the cutting tooth body 12 is detected by the principle of triangulation. Since the relative angle difference between the light source and the sensor fixed on the chassis remains constant, the three-dimensional contour height coordinates of the surfaces of the connecting plate body 11 and the cutting tooth body 12 can be calculated, thereby determining whether the cutting teeth are worn.
[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
