7. A belt conveyor idler loosening detection device according to claim 6, characterized in that: The top end of the supporting table (76) is provided with an arc-shaped recess (761), and a plurality of uniformly distributed rolling balls (77) are rolling clamped in the arc-shaped recess (761).

8. A method of detecting a loose belt conveyor idler according to any one of claims 1-7, characterized in that, The method comprises the following steps: Step one, assemble the belt conveyor idler, fix the mounting frame (1) on the belt conveyor frame, the flat idler (2) is detachably installed in the first mounting seat (43), the installation and fixation of the flat idler (2) is carried out, the inclined idler (3) is detachably installed in the second mounting seat (44), the installation and fixation of the inclined idler (3) are carried out, rotate the second mounting seat (44), the second mounting seat (44) rotates stably with the rotation shaft (45) as the axis, so as to adjust the angle of the second mounting seat (44), and then adjust the angle of the inclined idler (3), when the angle of the inclined idler (3) is adjusted, screw the positioning nut (461), so that the positioning nut (461) and the outer wall of the connecting vertical frame (41) are in contact, so as to fix the positioning bolt (46), and then fix the second mounting seat (44) and the inclined idler (3), the flat idler (2) and the inclined idler (3) can support the belt in the belt conveyor, and support the side of the belt in an inclined state, then fix the detection frame (5) on the belt conveyor frame, make the first positioning convex (47) movably connected in the first positioning groove (641), make the second positioning convex (48) movably connected in the second positioning groove (661), assemble the detection mechanism (6) and the connecting piece (4); Step two, when the mounting frame (1) is loose, the flat idler (2) and the inclined idler (3) move horizontally, which drives the rotation shaft (45) and the first positioning convex (47) to drive the first positioning cylinder (64) to move horizontally, so as to drive the translation detection frame (62) to slide in the detection outer frame (61), drive the pointer (68) to slide, cooperate with the observation detection groove (681), can automatically and intuitively detect that the flat idler (2) and the inclined idler (3) move horizontally, which is convenient for subsequent adjustment of the flat idler (2) and the inclined idler (3), and prevents the belt from deviating; When the positioning nut (461) is loose, the inclined idler (3) rotates vertically, which drives the second mounting seat (44) to rotate stably with the rotation shaft (45) as the axis, the positioning bolt (46) slides in the positioning sliding groove (412), so as to drive the second positioning cylinder (66) to slide in the angle detection frame (65), the second positioning cylinder (66) slides in the angle detection frame (65) and drives the detection convex (67) to slide in the detection slot (671), which can automatically and intuitively detect that the inclined idler (3) rotates vertically, which is convenient for subsequent adjustment of the inclined idler (3), and prevents the belt from deviating; Step three, when the detection of flat roller (2), inclined roller (3) horizontal loose movement, the bottom position of the stable card (63) will press the first touch switch (69), the first touch switch (69) control telescopic cylinder (73) stretch, drive protection pad (74) stretch, protection pad (74) and connecting frame (42) contact, and drive the whole connecting piece (4), mounting frame (1) horizontal movement, so as to drive the flat roller (2), inclined roller (3) horizontal movement, to the flat roller (2), inclined roller (3) horizontal direction in time to correct the deviation, prevent the belt from shifting; When the detection of flat roller (2), inclined roller (3) horizontal loose movement, the second positioning cylinder (66) will press the second touch switch (610), the second touch switch (610) control lifting cylinder (75) stretch, support table (76) up, inclined roller (3) on the arc groove (761), until the plurality of ball (77) and arc groove (761) contact, support table (76) continue to move up, drive inclined roller (3) rotation reset, to the inclined roller (3) vertical direction in time to correct the deviation, prevent the belt from shifting.
