[0031] In order to further explain the technical solution of the present utility model, the present utility model will be elaborated in detail through specific embodiments below.

[0032] An intelligent operation and maintenance system for a long-distance belt conveyor disclosed in this embodiment. The long-distance belt conveyor is comprehensively and intelligently detected through the intelligent operation and maintenance system. The long-distance belt conveyor 1 is as Figure 1 、 7 、8 and 9 show. It generally includes a roller drive mechanism 11 stably installed on a machine base and a belt 12 wound around the roller drive mechanism 11. The intelligent operation and maintenance system includes a detection hardware device and a digital twin visualization platform, and the two are interconnected by data. The platform function architecture is set by a software system, which is not specifically disclosed in this embodiment. The detection hardware device includes a patrol track 2 as Figure 1-9 shown, a patrol robot 3, an upper visual detection module 4, an emergency stop device 5, a deviation protection device 6, a belt tearing visual detection module 7, an augmented reality intelligent wearable device 8, etc. The specific structural settings and position connection relationships of each part of the detection hardware device will be described in detail below with reference to the drawings.

[0033] The patrol track 2, as Figure 1 and Figure 7 shown, is arranged on the outer side of the long-distance belt conveyor 1 in a loop. In this embodiment, the patrol track 2 has a cross-section in the shape of an I-beam structure. The middle arm of the I-beam is the web 21 corresponding to the vertical setting. The upper and lower cross arms of the I-beam are the upper flange 22 and the lower flange 23 respectively. Its fixed installation is realized by a plurality of bracket connectors arranged at intervals below on the lower surface of the lower flange 22, without affecting the normal operation of the patrol robot 3.

[0034] The patrol robot 3, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 、 Figure 6As shown, during the inspection work, it runs on the inspection track 2 and inspects the long-distance belt conveyor from the side direction. In this embodiment, the inspection work is mainly carried out visually, and other sensor devices can be set according to the actual inspection items. The inspection robot 3 in this embodiment includes a protective cover 31 with an internal operation adjustment space 311, a driving module 33 and a driven module 34 respectively installed and connected to the inner top surface of the protective cover 31 through a slewing bearing 32 and capable of adaptively detecting the turning adjustment of the track 2, a positioning wheel 35 erected and connected to the protective cover 31 and rotationally connected with an encoder 351, a multi-dimensional movement module 36 installed on the side surface of the protective cover 31, and an inspection vision device 37 arranged on the multi-dimensional movement module 36. The inspection robot 3 runs stably clamped on the inspection track 2 through the driving module 33 and the driven module 34. It can be seen from the above that the driving module 33 and the driven module 34 respectively have a slewing function and are two independently adjustable parts, and the operation adjustment space 311 in the protective cover 31 is sufficient for adjustment and movement. Therefore, the inspection robot 3 can achieve flexible turning operation. The positioning wheel 35 rolls on the surface of the inspection track, and the encoder 351 thereon can be encoded through the rotation of the wheel. The system can realize the running positioning of the inspection robot 3 through this information. The inspection vision device 37 is driven by the multi-dimensional movement module 36 to adjust its orientation in the height direction and relative depth direction relative to the long-distance belt conveyor 1, so as to visually detect different positions inside the long-distance belt conveyor. The protective cover 31 is provided with a door opening 312 for the inspection track 2 to pass through the inside and cooperate with the driving module 33 and the driven module 34. The protective cover 31 can play a role in dust prevention and protection. Its lower surface is an open mouth to avoid the installation bracket of the inspection track 1. The width of the door opening 312 is set to be able to pass through the turning arc of the inspection track 1.

[0035] As shown in the figure in this embodiment, the active module 33 includes a doorframe-shaped main frame 331, driving wheels 332 whose two wheel shafts are perpendicular to the side panels of the main frame 331 and are symmetrically spaced and supported on the inner sides of the two side panels of the main frame 331 respectively, main vertical guiding wheels 333 whose two wheel shafts are perpendicular to the side panels of the main frame 331 and are symmetrically spaced and installed and connected to the inner sides of the two side panels of the main frame 331 through height adjustment structures respectively, main horizontal guiding wheels 334 whose two wheel shafts are vertically installed and connected to the inner sides of the two side panels of the main frame 331 through mounting seats and are symmetrically spaced, and a driving transmission mechanism 335 installed and connected to the ends of the wheel shafts of the main frame 331 and the two driving wheels 332. As shown in the figure, the driving transmission mechanism 335 includes a driving motor fixedly installed on the main frame 331, a driving gear fixedly arranged on the output shaft of the driving motor, main driving gears respectively fixedly arranged on the ends of the wheel shafts of the two driving wheels 332, and a pair of transmission gear pairs installed on the main frame 331 and having two transmission gears respectively meshing with the two main driving gears. One end transmission gear of the transmission gear pair meshes with the driving gear. In this way, when the driving motor works, the two driving wheels 332 can be driven to rotate synchronously through the transmission gear pair. As shown in the figure, the height adjustment structure of the main vertical guiding wheel 333 is that vertical strip-shaped adjustment holes are formed on the side panels of the main frame 331. By adjusting the height position of the wheel shaft of the main vertical guiding wheel 333 in the adjustment holes, the height of the main vertical guiding wheel 333 can be changed, so as to ensure that the inspection robot 3 walks along the inspection track 2 in the vertical direction. The wheel shaft of the main horizontal guiding wheel 334 is a wheel shaft with an eccentric section structure. As shown in the figure, its upper section and lower section have different axes. In this way, by rotating the lower section locked on the mounting seat, the axis of its upper section will deflect at an angle, so as to ensure that the inspection robot 3 walks along the inspection track 2 in the horizontal direction, realize the required deflection position and spacing distance of the two main horizontal guiding wheels 334, and also realize a better guiding effect. Through the above structural settings, the active module 33 and the driven module 34 are more easily adapted to the rapid adjustment of operation and assembly. The assembly and operation cooperation relationship of the active module 33 on the inspection track 1 is as follows: the two driving wheels 332 respectively roll on the upper surfaces of the lower wing plates 23 on both sides of the web 21, the two main vertical guiding wheels 333 respectively roll on the lower surfaces of the upper wing plates 22 on both sides of the web 21, and the two main horizontal guiding wheels 334 respectively roll on the two side surfaces of the web 21.

The wheel axle of the horizontal driven guide wheel 344 is a wheel axle with an eccentric section structure. The two driven wheels 342 respectively roll on the upper surfaces of the lower wing plates 22 on both sides of the web 21, the two vertical driven guide wheels 343 respectively roll on the lower surfaces of the upper wing plates 22 on both sides of the web 21, and the two horizontal driven guide wheels 344 respectively roll on the two side surfaces of the web 21. The assembly and running cooperation relationship of the driven module 34 on the inspection track 1 can refer to the positional relationship between the above-mentioned driving module 34 and the inspection track 1, which will not be elaborated here. Through the respective assembly and running cooperation of the above-mentioned driving module 33 and driven module 34, the inspection robot 3 as a whole can be stably arranged and run on the inspection track 1 without bouncing up and down or swaying left and right.

[0037] As shown in the figure in this embodiment, the positioning wheel 35 is installed on the side edge of the protective cover 31 through a support arm with an elastic pulling structure. As shown in the figure, the support arm is in an L-shaped structure. One arm of the L shape is rotatable relative to the other arm for installing the positioning wheel 35 and the encoder 351, and the other arm is a circular rod clamped on a locking block. The elastic pulling structure is used to elastically pull the arm for installing the positioning wheel 35 and the encoder 351, so as to adapt to rolling on the upper surface of the upper wing plate 23 during actual assembly and use.

[0038] As shown in the figure in this embodiment, the multi-dimensional movement module 36 includes a vertical module fixedly installed on the protective cover 31 with a vertically sliding slider and a horizontal module fixedly installed on the slider of the vertical module. The inspection vision device 37 is fixedly installed on the slider of the horizontal module with its lens facing the direction of the long-distance belt conveyor 1. Thus, the height of the inspection vision device 37 is adjusted by the vertical module, and the depth of the inspection vision device 37 is adjusted by the horizontal module to realize visual inspection and adjustment of different orientations inside the long-distance belt conveyor 1.

[0039] The inspection robot 3 with the above structure has the following advantages: (1) The inspection robot is equipped with multiple module modules, which can expand the detection range of the inspection camera; (2) The inspection robot is arranged at a low position, which can detect the internal state of the belt conveyor, and the detection is more sufficient; (3) The inspection robot adopts an eccentric shaft structure to adjust the tension of the horizontal guiding module horizontally, with a simple structure and convenient adjustment; (4) The inspection robot adopts a vertical strip-shaped adjustment hole structure to adjust the tension of the vertical guiding module vertically, with a simple structure and convenient adjustment.

It includes a gantry spanning the long-distance belt conveyor 1 horizontally and an upper vision device 41 installed on the cross beam of the gantry corresponding to above the belt 12. The state of the upper part of the long-distance belt conveyor 1 can be detected through the image of the upper vision device 41.

[0041] The emergency stop device 5 is arranged on the long-distance belt conveyor 1, as Figure 7 shown in the figure, it is a pull rope switch protection device arranged at intervals along the length direction of the long-distance belt conveyor 1 on the side. This device is an existing product that can be directly purchased in the market, which is convenient for manual operation to be safe and reliable in case of abnormality, so as to stop the equipment urgently.

[0042] The deviation protection device 6 is as Figure 8 shown, it has two corresponding retaining wheels 61 corresponding to the two side edges of the belt 12. In this embodiment, multiple pairs of the deviation protection device 6 are arranged at intervals along the two corresponding side edges of the long-distance belt conveyor 1. This device is an existing product that can be directly purchased in the market. During operation, contact sensing is realized through the two retaining wheels 61, and it can give an alarm in time when the belt 12 deviates.

[0043] The belt tearing vision detection module 7 includes a laser transmitter 71 arranged opposite to the belt surface, a belt detection vision device 72, and a blowing device 73 that can blow air to clean the area facing the laser transmitter 71 and the belt detection vision device 72. When this module works, the laser transmitter 71 emits a laser line onto the belt 12, and the belt detection vision device 72 judges whether the belt is torn by detecting the state of the laser line on the belt. The blowing device 73 can ensure the cleanliness of the laser transmitter 71 and the belt detection vision device 72 to make the belt tearing detection more accurate.

[0044] The augmented reality intelligent wearable device 8 is worn by manual inspection personnel for detection. It is data-connected to the digital twin visualization platform. It can use an existing product, an AR glasses, worn by workers. When workers need to inspect, it can dynamically display the latest state of current various devices along with the direction of people's eyes, and the display is intuitive.
