Description

Technical Field

[0001] This utility model relates to the field of coal safety technology, specifically a protective shell for a personnel positioning device in underground coal mines. Background Technology

[0002] Personnel positioning equipment in coal mines is an important safety device. Its core components typically include positioning base stations, positioning tags, back-end servers, and display terminals.

[0003] When installing existing positioning equipment underground, protective covers are usually installed to protect the positioning equipment. However, the installation of existing protective equipment is usually done by fixing it with bolts, which is cumbersome and slow. It is also troublesome to disassemble and inspect the internal positioning equipment later. In addition, the connection wires of the positioning equipment are usually installed through the protective cover, but during use, they are prone to being pulled and detached from the positioning equipment, which will affect the normal operation of the equipment. Utility Model Content

[0004] To address the problem that existing protective equipment is cumbersome to install, and that the connection wires of positioning devices are usually installed through the protective cover, which can easily lead to pulling and detachment of the connection wires from the positioning device during use, affecting the normal operation of the equipment; the purpose of this utility model is to provide a protective shell for personnel positioning equipment in coal mines.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a protective shell for personnel positioning equipment in coal mines, including a fixed plate, a worm gear rotatably mounted on the middle of one side of the fixed plate, a worm rotatably mounted on one side of the fixed plate and meshing with the worm gear, a second gear fixedly mounted on one side of the worm gear, a first gear fixedly mounted on one side of the second gear, two symmetrically distributed tooth plates on one side of each of the first and second gears and meshing with the first and second gears, four tooth plates slidably locked in the middle of the fixed plate, a limit block fixedly mounted on one side of each of the four tooth plates, a positioning device installed in the middle of the fixed plate, and a protective cover provided on the side of the fixed plate near the positioning device. By setting the worm gear and worm, the worm gear and worm structure has a self-locking function, so that after the limit block limits the protective cover, it will not reset, thus making the fixed installation of the protective cover 2 more stable and reliable.

[0006] Preferably, a double-ended screw is rotatably installed on one side of the lower part of the protective cover, and clamping plates are threaded on both sides of the double-ended screw. Four symmetrically distributed clamping blocks are fixedly installed on the opposite sides of the two clamping plates, and anti-slip pads are fixedly installed on the opposite sides of the multiple clamping blocks. By setting anti-slip pads, the clamping and fixing of the connection limit of the positioning device can be made more stable, and slippage can be avoided.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. This application enables more convenient installation, fixing and disassembly of the protective cover outside the positioning device, simplifies the maintenance process of the positioning device, reduces labor intensity, enables rapid response to equipment failures, improves maintenance efficiency, ensures stable operation of the equipment, and thus extends its service life.

[0009] 2. This application can fix the connection line of the positioning device, thereby preventing the line from becoming loose or damaged, ensuring stable signal transmission, reducing safety hazards, and improving the safety of operation. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1-7 As shown, this utility model provides a protective shell for personnel positioning equipment in coal mines, including a fixed plate 1. A worm gear 14 is rotatably mounted on the center of one side of the fixed plate 1, and a worm 13 is rotatably mounted on one side of the fixed plate 1, with the worm 13 meshing with the worm gear 14. A second gear 16 is fixedly mounted on one side of the worm gear 14, and a first gear 15 is fixedly mounted on one side of the second gear 16. Both the first gear 15 and the second gear 16 have two symmetrically distributed toothed plates 17 on one side, and the toothed plates 17 are connected to the first gear 15 and the second gear 16. Two gears 16 mesh with each other, and four toothed plates 17 are slidably locked in the middle of the fixed plate 1. Limiting blocks 18 are fixedly installed on one side of each of the four toothed plates 17. A positioning device 3 is installed in the middle of the fixed plate 1. A protective cover 2 is provided on the side of the fixed plate 1 near the positioning device 3. By setting a worm gear 14 and a worm 13, the structure of the worm gear 14 and the worm 13 has a self-locking function, so that after the limiting block 18 limits the protective cover 2, it will not reset, thus making the fixed installation of the protective cover 2 more stable and reliable.

[0021] A double-headed screw 21 is rotatably installed on one side of the lower part of the protective cover 2. Clamping plates 22 are threaded on both sides of the double-headed screw 21. Four symmetrically distributed clamping blocks 23 are fixedly installed on the opposite sides of the two clamping plates 22. Anti-slip pads 24 are fixedly installed on the opposite sides of the multiple clamping blocks 23. By setting the anti-slip pads 24, the connection limit of the positioning device 3 can be clamped and fixed more stably, and slippage can be avoided.

[0022] A first handle 12 is fixedly installed on one side of the top end of the worm gear 13, and a second handle 211 is fixedly installed on one end of the double-ended screw 21. By setting the first handle 12 and the second handle 211, rotating the first handle 12 can drive the worm gear 13 to rotate, and rotating the second handle 211 can drive the double-ended screw 21 to rotate.

[0023] Four evenly distributed grooves 181 are provided on one side of the fixed plate 1. The four limiting blocks 18 are slidably opened inside the grooves 181. By setting the grooves 181, the limiting blocks 18 can move more stably under the drive of the toothed plate 17 under the limitation of the grooves 181.

[0024] The protective cover 2 has four evenly distributed limiting grooves 182 on one side. The four limiting blocks 18 are slidably locked inside the limiting grooves 182 on one side. By setting the limiting grooves 182, the limiting blocks 18 can be locked inside the limiting grooves 182, and the protective cover 2 can be fixedly installed.

[0025] A slot 26 is provided on one side of the fixing plate 1, and one side of the protective cover 2 is slidably locked inside the slot 26. By setting the slot 26, one end of the protective cover 2 can be easily limited, thereby making the installation of the protective cover 2 more secure.

[0026] A limiting rod 25 is fixedly installed on one side of the lower part of the protective cover 2, and the other side of the two clamping plates 22 is slidably locked on the outer surface of the limiting rod 25. By setting the limiting rod 25, the two clamping plates 22 can be limited, thereby ensuring that when the double-headed screw 21 rotates, it can drive the clamping plates 22 to move relative to each other and will not rotate with the double-headed screw 21.

[0027] Two symmetrically distributed mounting blocks 11 are fixedly installed on both sides of the fixing plate 1. By setting the mounting blocks 11, the mounting blocks 11 are fixed by passing bolts through them, thus making it convenient to fix and install the fixing plate 1.

[0028] Working principle: In actual use, by sliding one side of the protective cover 2 into the slot 26, rotating the first handle 12 drives the worm gear 13 to rotate, which in turn drives the worm wheel 14 to rotate, thereby causing the first gear 15 and the second gear 16 to rotate, thereby driving the tooth plate 17 to slide in the middle of the fixed plate 1, so that the limiting block 18 slides into the limiting groove 182, thereby fixing the protective cover 2 in place.

[0029] After the connecting wire of the positioning device 3 is passed through the small hole at the bottom of the protective cover 2, the double-headed screw 21 is rotated by rotating the second handle 211, which causes the two clamping plates 22 to move relative to each other, that is, causes the clamping block 23 to move relative to each other to clamp and fix the connecting wire.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
