DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0043] Please refer to Figures 1-5 In the embodiments of the present application, a mine belt conveyor inspection robot comprises a main body frame 1, a support foot structure 2, a power supply structure 3 and a visual detection structure 4. The main body frame 1 comprises a top frame 101, and support columns 109 are fixedly installed at the bottom side of the four corners of the top frame 101. The support foot structure 2 comprises a conical gear ring 201 and an angle code base 207. The conical gear ring 201 is rotatably installed at the lower end of the support column 109 through a bearing 203. Threaded holes 202 are formed in the middle of the conical gear ring 201, and top rods 204 are rotatably installed in the threaded holes 202 through twisting threads 206. The angle code base 207 is fixedly installed on the inner side surface of the lower end of the support column 109, and an electric wheel 208 is fixedly installed on the bottom side of the angle code base 207. The power supply structure 3 is fixedly installed on the upper side of the top frame 101. The visual detection structure 4 is fixedly installed on the bottom side of the top frame 101.

[0044] Specifically, the lower ends of the support columns 109 on both sides of the top frame 101 abut against the side surfaces of the conveyor frame on both sides, and the electric wheel 208 abuts against the upper surface of the side frames, so that the entire main frame 1 spans across the belt conveyor. The rotation of the conical toothed ring 201 controls the movement of the top rod 204 through the screwing action of the threaded through hole 202 and the rubbing thread 206, so that the top rod 204 abuts against the side surface of the frame to achieve relative clamping and limiting, and fixes the whole device relatively at a certain point on the belt conveyor. The suspended visual inspection structure 4 continuously inspects the moving conveyor belt. When it is necessary to inspect the relatively fixed components such as the belt support roller, the top rod 204 can be retracted to release the limitation, and the electric wheel 208 drives the whole structure to move on the side frame for inspection. It has two working modes and can select different inspection methods according to the inspection requirements.

[0045] Example 1

[0046] like Figures 1-3 As shown, in this embodiment, the main frame 1 also includes a base beam 102, a dual-output shaft motor 103, a drive shaft 104, a worm gear 105, a worm wheel 106, a linkage shaft 107, and a drive shaft 108. The base beam 102 is fixedly installed in the middle of the top frame 101; the dual-output shaft motor 103 is rotatably installed inside the base beam 102; the drive shaft 104 is rotatably installed inside the base beam 102, and the drive shaft 104 is fixedly connected to the output ends on both sides of the dual-output shaft motor 103; the worm gear 105 is rotatably installed inside both sides of the top frame 101, and the worm gear 105 is fixedly installed at one end of the drive shaft 104. The worm gear 106 is rotatably installed inside both sides of the top frame 101, and the worm gear 106 meshes with the worm 105. The linkage shaft 107 is rotatably installed inside both sides of the top frame 101, and the middle part of the linkage shaft 107 is fixedly sleeved with the worm gear 106. The drive shaft 108 is rotatably installed inside the support column 109, and the two ends of the linkage shaft 107 are interconnected with the upper ends of the two drive shafts 108 through a bevel gear set. The lower end of the drive shaft 108 is interconnected with the bevel gear and the conical toothed ring 201 through a bevel gear. A top plate 205 is fixedly installed at one end of the top rod 204, and the top plate 205 is embedded in the inner surface of the lower end of the support column 109.

[0047] In this embodiment, the dual-output shaft motor 103 controls the drive shaft 104 to rotate, which in turn drives the worm gear 105 to rotate the worm wheel 106, thereby controlling the rotation of the two linkage shafts 107. The bevel gear set then drives the shaft 108 to rotate, simultaneously controlling the four conical toothed rings 201. This, in turn, controls the four push rods 204, and the top plate 205 abuts against the side surface of the conveyor belt to perform the limiting operation.

[0048] like Figure 4As shown, in this embodiment, the power supply structure 3 includes a power supply box 301, a battery compartment 302, a replaceable battery 303, and a handle 304. The power supply box 301 is fixedly installed on the upper surface of the base beam 102; the battery compartment 302 is fixedly installed on the upper surface of the power supply box 301; the replaceable battery 303 is sealed and snapped onto the upper side of the battery compartment 302; and the handle 304 is fixedly installed on the upper surface of the replaceable battery 303.

[0049] In practice, when replacing the battery, the entire device needs to be moved to the mine exit via the conveyor belt. The replaceable battery 303 is then pulled up by the handle 304 and inserted into the battery compartment 302 for installation. The interface between the replaceable battery 303 and the battery compartment 302 is sealed with a rubber seal.

[0053] In practice, when the overall device is used to inspect the conveyor belt in motion, the overall visual inspection structure 4 is in a folded state, and the visual inspection head 406 is positioned above the center line of the conveyor for inspection. When performing routine inspections, the first-level folding rod 403 and the second-level folding rod 404 are unfolded by the drive motor 405 and slide on the linear motor slide rail 401 via the slide block 402, giving the visual inspection head 406 the ability to move, so as to bypass the obstruction of the belt and perform visual inspections on some structures.
