Description

Technical Field

[0001] This utility model relates to the field of positioning and navigation magnetic strip technology, specifically to a positioning and navigation magnetic strip for a coal conveyor belt inspection robot. Background Technology

[0002] The magnetic strip navigation technology used in coal conveyor belt inspection robots is a navigation method that achieves precise positioning by laying magnetic materials on the ground. Its core principle is to use an array of magnetic sensors onboard the robot to detect magnetic field signals. By measuring changes in the magnetic field strength of magnetic strips or nails, the robot determines its own position and thus travels along a preset path. This technology has advantages such as high measurement accuracy, strong anti-interference ability, and low maintenance cost, but it also has limitations such as fixed paths, the need for pre-laying magnetic strips, and susceptibility to interference from metallic substances. In coal conveying scenarios, it is often used in conjunction with RFID (Radio Frequency Identification) technology. Magnetic strips are used for main path navigation, while RFID tags are used for precise positioning at key stopping points.

[0003] Traditional positioning and navigation magnetic strips are mostly one-piece long strips. During installation, the amount of on-site cutting work is large. They are also less practical and have a shorter service life due to the corrosion of coal slurry and oil in the coal transportation environment, resulting in increased replacement frequency and inconvenience for maintenance.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figures 1-4As shown, this utility model provides a technical solution: a positioning and navigation magnetic strip for a coal conveyor belt inspection robot, including a high-strength magnetic strip 1. A modular connecting mechanism 2 is provided at the end of the high-strength magnetic strip 1. The modular connecting mechanism 2 makes the high-strength magnetic strip 1 a standard modular unit, for example, 1.5 meters in length. The modular connecting mechanism 2 includes a connecting frame 21 and a connecting piece 22. The connecting frame 21 is fixedly connected to one end of the high-strength magnetic strip 1, and the connecting piece 22 is fixedly connected to the other end of the high-strength magnetic strip 1. The high-strength magnetic strip 1 includes a fully enclosed sealing structure 12, the inner cavity of which... The device includes a positioning and navigation magnetic strip body 11. By inserting the connecting clip 22 into the inside of the connecting clip frame 21, the splicing of two high-strength magnetic strips 1 is completed, which is convenient to operate. The fully enclosed sealing structure 12 is made of thermoplastic polyurethane, which provides all-round protection for the positioning and navigation magnetic strip body 11. It can extend the service life of the positioning and navigation magnetic strip body 11 against the corrosion of coal slurry and oil in the coal conveying environment. The fully enclosed sealing structure 12 has high elasticity and wear resistance, is resistant to oil and coal slurry corrosion, and is not easy to crack at low temperatures. It can achieve seamless encapsulation of the magnetic strip through extrusion process, which is suitable for most coal conveying workshop environments.

[0017] As one implementation method in this embodiment, such as Figure 4 As shown, a reinforcing rib 13 is fixedly connected to the outer wall of the fully enclosed sealing structure 12. The top of the fully enclosed sealing structure 12 is coated with a wear-resistant coating 14. The reinforcing rib 13 is a polyester fiber mesh core, which can improve the longitudinal tensile strength of the high-strength magnetic strip 1 and prevent the magnetic strip from breaking due to dragging, ground settlement, etc. The wear-resistant coating 14 is a ceramic particle reinforced coating, which improves the surface hardness and scratch resistance of the high-strength magnetic strip 1 and extends its service life.

[0018] As one implementation method in this embodiment, such as Figure 4 As shown, the bottom of the fully enclosed sealing structure 12 is fixedly connected to an adhesive layer 15, and the bottom of the adhesive layer 15 is movably connected to a non-adhesive paper 16. The adhesive layer 15 uses low-residue silicone adhesive, which combines strong adhesion and easy peeling, solving the problem of traditional adhesives being difficult to clean after long-term use and damaging the ground when replacing them. After the non-adhesive paper 16 is peeled off, the high-strength magnetic strip 1 can be connected to the ground with the help of the adhesive layer 15.

[0019] As one implementation method in this embodiment, such as Figure 2 As shown, an elastic element 23 is fixedly installed on the inner wall of the connecting clip 22, and a movable block 24 is fixedly installed at the end of the elastic element 23. The entire modular connecting mechanism 2 is made of plastic. The elastic element 23 is made of elastic plastic material and can be axially compressed to facilitate the insertion operation.

[0020] As one implementation method in this embodiment, such as Figure 2As shown, when the connecting clip 22 is inserted into the inside of the connecting clip frame 21, the inclined surface of the sliding clip 25 will contact the connecting clip frame 21. The sliding clip 25 is fixedly installed on the outer wall of the moving block 24. The sliding clip 25 is slidably connected to the inner wall of the connecting clip 22. Under the action of the insertion force, the sliding clip 25 can be slid on the inner wall of the connecting clip 22, and the elastic member 23 is axially compressed by the moving block 24.

[0021] As one implementation method in this embodiment, such as Figure 2 As shown, a connecting slot 211 is provided on the side of the connecting frame 21. The sliding tooth 25 and the connecting slot 211 have the same axial cross section. When the connecting card 22 is fully inserted into the interior of the connecting frame 21, the elastic force of the elastic member 23 can push the sliding tooth 25, causing the sliding tooth 25 to be inserted into the interior of the connecting slot 211, thus completing the locking.

[0022] As one implementation method in this embodiment, such as Figure 3 As shown, a protrusion 212 is fixedly connected to the outer wall of the connecting frame 21, and a slide rod 213 is slidably connected to the inner wall of the protrusion 212. A limit block 214 is fixedly connected to the end of the slide rod 213. If it is necessary to disconnect the modular connecting mechanism 2, the slide rod 213 can be pressed towards the connecting frame 21, and the sliding tooth 25 can be pushed inward by the slide rod 213, thereby allowing the connecting clip 22 to be pulled out from the inside of the connecting frame 21.

[0023] Working principle: In use, the connecting clip 22 is inserted into the connecting clip frame 21, thus completing the splicing of the two high-strength magnetic strips 1. During insertion, the inclined surface of the sliding tooth 25 contacts the connecting clip frame 21. Under the action of the insertion force, the sliding tooth 25 can slide on the inner wall of the connecting clip 22. With the help of the moving block 24, the elastic element 23 is axially compressed. When the connecting clip 22 is fully inserted into the connecting clip frame 21, the elastic force of the elastic element 23 can compress the sliding tooth. Push 25 to cause the sliding tooth 25 to insert into the connection slot 211 and lock it in place. If it is necessary to disconnect the modular connection mechanism 2, press the slide bar 213 on the connection frame 21 and push the sliding tooth 25 inward with the slide bar 213. Then the connection card 22 can be pulled out from the inside of the connection frame 21. After the high-strength magnetic strip 1 is placed on the path, peel off the non-stick paper 16 and use the adhesive layer 15 to connect the high-strength magnetic strip 1 to the ground.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
