Description

Technical Field

[0001] The present invention relates to the technical field of underground coal mine positioning, and in particular to an anti-collision warning device based on UWB precise positioning. Background Technique

[0002] In coal mine production, the underground mining method is the most important one. Therefore, studying underground mining technology has very important practical significance. The application of underground mining technology must adapt to the coal mine geology and coal seam distribution. And a mining plan should be formulated in advance to determine the application of equipment and the support method. In open-pit mining, the direct mining method is generally adopted, but in underground mining, due to restrictions of conditions such as the environment and equipment, the mining method from top to bottom is usually adopted.

[0003] In the underground auxiliary transportation system, there are many vehicles, long routes, and poor visibility. The underground conditions are relatively poor. Most transportation locomotives and pedestrians share the roadway, and there is an easy risk of collision between people and vehicles. The driving safety is low, and accidents are likely to occur, affecting coal mine mining. To make up for the above deficiencies, the existing Chinese patent document CN202311548452.9 discloses an anti-collision warning device based on UWB precise positioning, including a fixed housing, a UWB positioning card reader, and a UWB electronic tag card. The UWB positioning card reader is clamped in the fixed housing. One side of the fixed housing is slidably connected with a clamping bracket, and two bearing blocks are fixed on the back. Two elastic members are sleeved on one side of the clamping bracket. The UWB positioning card reader is fixed on the underground vehicle and can remotely identify the information of the UWB electronic tag card. During the movement of the underground vehicle, it can timely give an alarm to the personnel wearing the UWB electronic tag card, and give a warning prompt through the alarm to alert the driver to pay attention to safety and avoid collisions.

[0004] Although the UWB positioning card reader in the above-mentioned solution can be clamped in the fixed housing, when the UWB positioning card reader vibrates due to the bumping of the underground vehicle during use, the UWB positioning card reader fixed by clamping with elastic members will vibrate with the bumping of the vehicle, and the fixing effect is poor. With the long-term use of the vehicle, in the lightest case, the UWB positioning card reader may be damaged, and in the worst case, the UWB positioning card reader may fall off from the fixed housing.

DETAILED DESCRIPTION OF THE INVENTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1: Please refer to Figure 1 、 Figure 2 and Figure 7 , a collision prevention warning device based on UWB precise positioning in the figure, including a fixed housing 1 and a UWB positioning card reader 2. The UWB positioning card reader 2 is arranged inside the fixed housing 1. Additionally, it also includes a UWB electronic tag card (not labeled in the figure). The UWB electronic tag card and the UWB positioning card reader 2 interact with each other. The UWB electronic tag card can send pulse information to the positioning base station according to the set communication frequency, thereby realizing the real-time precise positioning of the wearer. The UWB positioning card reader 2 is fixed on the underground vehicle and can remotely identify the information of the UWB electronic tag card. During the movement of the underground vehicle, it can timely send an alarm to the person wearing the UWB electronic tag card, and give a warning prompt through the alarm, warning the driver to pay attention to safety and avoid collisions.

[0029] The specific model specifications of the above UWB positioning card reader 2 and UWB electronic tag card need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated in detail.

[0030] It further includes: clamping units 3 installed on both sides of the UWB positioning card reader 2. The two groups of clamping units 3 are used to fix the UWB positioning card reader 2. A lifting housing 6 is arranged inside the fixed housing 1. The UWB positioning card reader 2 is fixed in the lifting housing 6 through the clamping units 3. A protective cover plate 7 is rotatably connected to the top of the fixed housing 1. A driving unit 4 is installed at one end of the lifting housing 6. A linkage unit 5 is arranged on one side of the fixed housing 1. The output end of the linkage unit 5 is fixedly connected to the protective cover plate 7. Under the action of the designed clamping units 3 and driving unit 4, the clamping and fixing of the UWB positioning card reader 2 is realized. It can install the UWB positioning card reader 2 and the fixed housing 1 with greater clamping force on both sides. Compared with the existing spring clamping method for positioning, the UWB positioning card reader 2 will not vibrate due to the bumps of the vehicle, and the fixing effect is better. Moreover, when loosening, the UWB positioning card reader 2 can be removed from the inside of the fixed housing 1, which is convenient for personnel to take and place the UWB positioning card reader 2.

[0031] Further, refer to Figure 3, the clamping unit 3 includes a U-shaped clamping plate 31, a horizontal stud 32, a horizontal threaded barrel 33, a first limiting plate 34, a first gear 35 and a fixed rack 36. One end of the horizontal stud 32 is fixedly connected to the U-shaped clamping plate 31. The horizontal threaded barrel 33 is threadedly connected to the horizontal stud 32. The horizontal threaded barrel 33 is rotatably connected to the top of the lifting shell 6 through two of the first limiting plates 34. The first gear 35 is fixedly sleeved on the outside of the horizontal threaded barrel 33. The fixed rack 36 is meshed with the first gear 35. One side of the fixed rack 36 is fixedly connected to the fixed shell 1 through a fixing plate. Sliding bars 37 are fixed on both sides of the U-shaped clamping plate 31. The sliding bars 37 are slidably connected to the sliding grooves formed on the lifting shell 6.

[0032] The principle of clamping and fixing the UWB positioning card reader 2: The driving unit 4 drives the lifting shell 6 to move downward inside the fixed shell 1. During the downward movement, the meshing between the first gear 35 and the fixed rack 36 drives the horizontal threaded barrel 33 to rotate, thereby driving the horizontal stud 32 to move horizontally, so that the U-shaped clamping plate 31 fixed at one end of the horizontal stud 32 moves closer to the UWB positioning card reader 2 until the UWB positioning card reader 2 fits against the inner wall of the U-shaped clamping plate 31, and then the clamping and fixing of the UWB positioning card reader 2 is achieved.

[0033] It should be noted that since there are two groups of clamping units 3, the thread directions of the two symmetrically distributed horizontal studs 32 are set in opposite directions, so that the two U-shaped clamping plates 31 can move closer to or away from each other.

[0034] Further, referring to Figure 4 , the driving unit 4 includes a vertical stud 41, a vertical threaded barrel 42, a second limiting plate 43 and a driving rod 44. The vertical stud 41 is threadedly connected to the vertical threaded barrel 42. The vertical threaded barrel 42 is fixedly sleeved on one end of the lifting shell 6. The two sides of the vertical stud 41 are rotatably connected to the fixed shell 1 through two of the second limiting plates 43. The driving rod 44 is fixed to the bottom end of the vertical stud 41. The input end of the linkage unit 5 is fixedly connected to the driving rod 44.

[0035] Among them, in order to facilitate the rotation of the driving rod 44, a rotating block 45 is fixed to the bottom end of the driving rod 44, and anti-slip lines are provided on the outside of the rotating block 45.

[0036] The principle of the driving unit 4 driving the lifting housing 6 to move: By manually rotating the rotating block 45 by a person, the rotating block 45 drives the vertical screw 41 to rotate, and then drives the vertical threaded cylinder 42 to move up and down. Since the vertical threaded cylinder 42 and the lifting housing 6 are fixed, the lifting housing 6 also moves up and down. When the lifting housing 6 moves up inside the fixed housing 1, the U-shaped clamp 31 will loosen the UWB positioning card reader 2, so that the UWB positioning card reader 2 can be removed from the inside of the fixed housing 1 together, facilitating the person to take and place the UWB positioning card reader 2. When the lifting housing 6 moves down inside the fixed housing 1, the U-shaped clamp 31 will clamp the UWB positioning card reader 2, facilitating the installation of the UWB positioning card reader 2 inside the fixed housing 1.

[0037] It should be noted that the thread pitch of the outer side of the vertical screw 41 is relatively large, and the transmission efficiency is higher. In this way, the person only needs to rotate a few turns to realize the rapid lifting and lowering movement of the lifting housing 6.

[0038] Further, please refer to Figure 2 , in order to facilitate the stable lifting and lowering movement of the lifting housing 6, vertical optical rods 13 are slidably sleeved at the four corners of the lifting housing 6, and the bottom ends of the vertical optical rods 13 are fixed to the inner bottom of the fixed housing 1.

[0039] Embodiment 2: Please refer to Figure 2 、 Figure 5 and Figure 8 , this embodiment further describes Embodiment 1, and the difference is that a linkage unit 5 is added to effectively protect the UWB positioning card reader 2.

[0040] Specifically, the linkage unit 5 includes a driving bevel gear 51, a driven bevel gear 52, a third limiting plate 53, a driving pulley 54, a driven pulley 55, a first transmission rod 56, a second transmission rod 57, a second gear 58, a third gear 59 and a sector gear 510. The driving bevel gear 51 is fixedly sleeved on the driving rod 44, the driven bevel gear 52 is meshed with the driving bevel gear 51, the driven bevel gear 52 and the driving pulley 54 are respectively fixedly sleeved at both ends of the first transmission rod 56, the third limiting plate 53 is fixedly connected to the bottom of the fixed housing 1 and is rotatably connected to the first transmission rod 56 through a bearing. A synchronous belt is connected between the driven pulley 55 and the driving pulley 54. One end of the second transmission rod 57 is rotatably connected to the fixed housing 1 through a bearing, the second gear 58 and the driven pulley 55 are both fixedly sleeved on the second transmission rod 57, the central axis of the third gear 59 is rotatably connected to the fixed housing 1 through a bearing, the second gear 58, the third gear 59 and the sector gear 510 are respectively meshed, and the central axis of the sector gear 510 is fixedly connected to the end of the protective cover plate 7.

[0041] The principle of the linkage unit 5 driving the protective cover plate 7 to rotate: When the driving rod 44 rotates, it will also drive the driving bevel gear 51 to rotate. The driving bevel gear 51 drives the driven bevel gear 52 to rotate. The driven bevel gear 52 drives the driving pulley 54 to rotate. The driving pulley 54 drives the driven pulley 55 to rotate through the synchronous belt. The driven pulley 55 drives the second transmission rod 57 to rotate. The second transmission rod 57 drives the second gear 58 to rotate. The second gear 58 drives the third gear 59 to rotate. The third gear 59 drives the sector gear 510 to rotate. The sector gear 510 drives the protective cover plate 7 to rotate, thereby realizing the automatic closing or opening of the protective cover plate 7 for the fixed housing 1. Among them, the protective cover plate 7 can close the top of the fixed housing 1 synchronously when limiting the UWB positioning card reader 2, preventing the UWB positioning card reader 2 from being damaged by external object collisions.

[0042] It should be noted that: the pitch circle diameters of the second gear 58, the third gear 59, and the sector gear 510 are arranged in an increasing manner. Through this decreasing setting, when the power is transmitted to these gears, their rotational speeds will gradually decrease, so as to achieve the purpose of deceleration, so as to enable the sector gear 510 to rotate within the range of 0-90°.

[0043] Figures 5 - 7 Embodiment 3: Please refer to Figures 5 - 7 , this embodiment further illustrates other embodiments, and the difference lies in optimizing the heat dissipation method of the UWB positioning card reader 2.

[0044] Specifically, strip-shaped through grooves 8 are uniformly arranged on the side wall of the fixed housing 1. A cleaning brush 9 for cleaning the dust on the surface of the strip-shaped through grooves 8 is attached to the outer side wall of the fixed housing 1. One end of the cleaning brush 9 is fixed with a sliding column 10. One end of the sliding column 10 is fixed to the end of the lifting housing 6. A limiting groove 11 adapted to the sliding column 10 is also opened on the outer side wall of the fixed housing 1; a heat dissipation fan 12 is fixedly installed on the protective cover plate 7, which is used to dissipate the heat generated by the UWB positioning card reader 2.

[0045] Specifically, after the UWB positioning card reader 2 is fixed inside the fixed housing 1, the heat generated when the UWB positioning card reader 2 works will be dissipated through the strip-shaped through grooves 8 and the heat dissipation fan 12 at the same time, thus improving the existing method that only uses heat dissipation holes, and greatly improving the heat dissipation efficiency when the UWB positioning card reader 2 works; in addition, when external air enters the fixed housing 1, flocculent dust will be adsorbed on the outside of the strip-shaped through grooves 8. When cleaning these dusts, only when the lifting housing 6 moves up and down will it drive the cleaning brush 9 to move, so as to clean the dust on the strip-shaped through grooves 8.

[0046] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.

[0047] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
