DETAILED DESCRIPTION

[0017] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0018] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the present invention. In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0019] like Figure 1-2 As shown, an embodiment of the present invention provides a wire rope core conveyor belt joint positioning marking device, including a positioning marking system control unit, a human-machine interaction unit and a frame 1. The device can locate and mark the wire rope core joint, greatly reducing the time required to find the wire rope core joint and improving the maintenance efficiency.

[0020] The frame 1 includes a base frame 11 and an arch frame 15. Universal wheels 13 are arranged at the four corners of the bottom of the base frame 11 to improve the mobility and flexibility of the device as a whole. One end of the bottom of the arch frame 15 overlaps one end of the base frame 11, and a rotating shaft 12 is arranged at the other end of the bottom of the arch frame 15. The rotating shaft 12 is connected to the base frame 11 through bearing seats arranged at both ends. The other end of the base frame 11 is hinged with a cylinder 14, and one end of the cylinder 14 is hinged to one side of the arch frame 15.

[0021] The expansion and contraction of the cylinder 14 is controlled by the human-machine interaction unit, so that the arch frame 15 can rotate around the rotating shaft 12 within a certain range. When using this device, the human-machine interaction unit sends a signal to shrink the cylinder 14, and the arch frame 15 is forced to turn outward, thereby realizing the opening of the arch frame 15. When the arch frame 15 is opened, the device can be easily moved to the bottom of the conveyor belt stand and adjusted to be perpendicular to the feeding direction of the conveyor belt. Then, the human-machine interaction unit controls the cylinder 14 to push the arch frame 15 to restore its original state. At this time, the arch frame 15 spans above the conveyor belt, preparing for the subsequent work process.

[0022] like Figure 2 and 3 As shown, an electromagnetic detection unit 2 is provided on one side of the top of the arch frame 15, and the electromagnetic detection unit 2 includes a linear module 21 (the linear module is a linear transmission device widely used in the industrial field. The working principle of the linear module is to convert the rotational motion of the servo motor into linear motion, thereby driving the slider to slide on the linear guide rail to achieve high-precision repetitive linear motion), a mounting plate 23, a fixed seat 25, a slide seat 27 and an electromagnetic detector 28.

[0023] The linear module 1 21 is fixedly mounted on one side of the top of the arch frame 15, and it provides the ability of linear motion in the horizontal direction. By controlling the linear module 1 21, the position of the electromagnetic detector 28 in the width direction of the conveyor belt can be adjusted. The output end of the linear module 1 21 is fixed with a profile adjustment seat 22, and multiple groups of mounting plates 23 are slidably connected to the profile adjustment seat 22 so that the position of the mounting plate 23 can be flexibly adjusted according to the width of the conveyor belt. Each mounting plate 23 is provided with a cylinder 24, and the output end of the cylinder 24 is connected to the fixed seat 25. By controlling the extension and contraction of the cylinder 24, the position of the fixed seat 25 in the vertical direction can be adjusted to adapt to conveyor belts of different heights.

[0024] Two sets of guide rods 26 passing through the slide 27 are arranged between the two side walls on one side of the fixed seat 25, and a cylinder three 29 is fixedly installed on the other side of the fixed seat 25, and the output end of the cylinder three 29 is fixed on one side of the slide 27, and the electromagnetic detector 28 is installed on the other side of the slide 27.

[0025] There are a total of multiple electromagnetic detectors 28 in the electromagnetic detection unit 2, which are arranged perpendicular to the moving direction of the conveyor belt. Each electromagnetic detector 28 is responsible for detecting the status of 4-8 steel wire rope cores. Each electromagnetic detector 28 is located on the belt surface of the conveyor belt and maintains a certain safety distance from the conveyor belt. Cylinder three 29 can independently control the position of each electromagnetic detector 28, greatly improving the system reliability and detection accuracy.

[0026] like Figure 2 and4 As shown, a speed detection unit 3 is provided on the crossbeam of the arch frame 15. The speed detection unit 3 includes a support frame 31 fixedly mounted on one side of the crossbeam of the arch frame 15, a vertical plate is provided at one end of the support frame 31, a support plate 34 is connected to one side of the vertical plate through a slide rail 37, and a speed measuring wheel 36 is fixed to the bottom of the support plate 34. A connecting seat 35 is provided on one side of the support plate 34, and a support seat 32 facing the connecting seat 35 is provided on the top side of the vertical plate. The support seat 32 is connected to a threaded adjustment rod 33 through a preset threaded hole, and one end of the threaded adjustment rod 33 is connected to the connecting seat 35. The operator adjusts the position of the support plate 34 by rotating the threaded adjustment rod 33, and then adjusts the contact state between the speed measuring wheel 36 and the conveyor belt surface. When the conveyor belt moves, the speed measuring wheel 36 will rotate accordingly, and its rotation speed is proportional to the moving speed of the conveyor belt being measured.

[0027] like Figure 2 and 5 As shown, a paint spraying unit 4 is provided on the other side of the top of the arch frame 15. The paint spraying unit 4 includes a linear module 2 41 fixedly mounted on the other side of the top of the arch frame 15, and a mounting seat 42 is provided at the output end of the linear module 2 41. The linear module 2 41 provides a linear motion capability in the horizontal direction, and the position of the mounting seat 42 in the width direction of the conveyor belt can be adjusted by controlling the linear module 2 41. A linear module 4 45 perpendicular to the linear module 2 41 is fixedly mounted on the mounting seat 42, and a linear module 3 43 perpendicular to the linear module 2 41 and the linear module 4 45 is fixed at the output end of the linear module 4 45, and a fixed plate 44 is provided at the output end of the linear module 3 43. The linear module 4 45 provides a linear motion capability in the horizontal direction, and the position of the linear module 3 43 in the length direction of the conveyor belt can be adjusted by controlling the linear module 4 45. The linear module 3 43 provides a linear motion capability in the vertical direction, and the position of the fixed plate 44 in the height direction of the conveyor belt can be adjusted by controlling the linear module 3 43.

[0028] On one side of the bottom of the fixed plate 44, there are multiple sets of cylinders 47 arranged side by side, and a paint spray gun 46 is fixed to the output end of each cylinder 47. The function of the cylinder 47 is to further adjust the position of the paint spray gun 46 to ensure that the paint spraying operation can be accurately aimed at the target area. By controlling the extension and contraction of the cylinder 47, the paint spray gun 46 can be quickly positioned and fine-tuned.

[0029] The positioning marking system control unit includes a speed detection unit interface connected to the speed detection unit 3 through a connecting line, an electromagnetic detection unit interface connected to the electromagnetic detection unit 2 through a connecting line, a paint unit interface connected to the paint unit 4 through a connecting line, a human-computer interaction unit interface connected to the human-computer interaction unit through a connecting line, and a microprocessor module connected to the above interfaces through a connecting line.

[0030] When the conveyor belt is running, the electromagnetic detection unit 2 detects the magnetic leakage of the steel wire rope core in real time. The microprocessor module determines the lap type of the joint according to the relationship between the magnetic leakage and the lap type of the joint, and calculates the time for the joint position to move to the paint spray gun 46 according to the speed measurement result of the speed measuring wheel 36. When the steel wire rope core joint moves to the paint spray gun 46, the paint spray gun 46 is started, and the detected joint lap type and length (such as Figure 6 as shown) in the corresponding pattern form (as shown Figure 7 as shown) is sprayed onto the conveyor belt.

[0031] According to the embodiments of the present invention as described above, these embodiments do not describe all the details in detail, nor do they limit the invention to specific embodiments. Obviously, many modifications and changes can be made based on the above description. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can make good use of the present invention and the modified use based on the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
