[0025] The present utility model will be further described below in conjunction with the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, and cannot be used to limit the protection scope of the present utility model.
[0026] The present utility model provides as Figure 1-4An encapsulated wireless charging structure for a mine explosion-proof hanging-rail inspection robot is shown, which includes a suspension rail 1, a wire 9, and a power transmission line 4. A hanging-rail robot 2 is slidably arranged on the suspension rail 1. A charging module 3 is detachably installed on the suspension rail 1. On one side of the hanging-rail robot 2 facing the charging module 3, there is a casting core 11. Inside the casting core 11, there is a receiving coil 10 for power conversion. Below the casting core 11 of the hanging-rail robot 2, there is an electro-suction device 8 for mutual adsorption. On one side of the charging module 3 facing the hanging-rail robot 2, there is a casting sleeve 16 that can wrap the casting core 11. Inside the casting sleeve 16, there is a power supply coil 21 for power conversion. Below the casting sleeve 16, there is also a travel switch 15 for controlling power supply. The casting sleeve 16 and the casting core 11 are coaxially arranged to achieve the best charging effect. The power transmission line 4 is connected to a charging component control module 18 for realizing power transmission to the power supply coil 21.
[0027] Inside the hanging-rail robot 2, there is a robot battery 5. The robot battery 5 is connected to a charging circuit module 6 through a wire 9. The output end of the receiving coil 10 is electrically connected to the charging circuit module 6. The charging circuit module 6 is used to provide stable and reliable power support for the hanging-rail robot 2 and to transmit the power converted by the receiving coil 10 into the robot battery 5.
[0028] The robot battery 5 is also connected to a robot controller 7 through a wire 9. The robot controller 7 is electrically connected to the electro-suction device 8 on one side of the hanging-rail robot 2 through a wire 9. The robot controller 7 is used to control the switch of the electro-suction device 8. Through the setting of the robot controller 7, when the battery is fully charged, the hanging-rail robot 2 can be released from the charging module 3, which is convenient for achieving the purpose of automatic charging.
[0029] The casting core 11 is encapsulated with a potting agent. On the end face of the casting core 11, there is an installation base 23. The installation base 23 is detachably connected to the hanging-rail robot 2. The setting of the installation base 23 is convenient for installing the casting core 11. At the same time, by changing the size of the installation base 23, the protruding length of the casting core 11 can be adjusted, thereby improving the charging effect.
[0030] Inside the charging module 3, there is a charging component control module 18. One end of the charging component control module 18 is connected to the power transmission line 4. The other end of the charging component control module 18 is electrically connected to the travel switch 15 through a wire 9. When the travel switch 15 is squeezed by the hanging-rail robot 2, the charging component control module 18 controls the power supply coil 21 to conduct power transmission. The power supply coil 21 monitors the location of the hanging-rail robot 2 through the travel switch 15 and controls the power supply through the charging component control module 18.
[0031] The casting sleeve 16 encapsulates the power supply coil 21 inside with potting compound. The input end of the power supply coil 21 is electrically connected to the charging component control module 18. The potting compound can be epoxy resin, which has excellent electrical insulation performance, can effectively prevent current leakage and breakdown, and ensure the safe operation of electrical equipment.
[0032] An electro-sucker 8 is arranged on the end face of the charging module 3. The electro-sucker 8 of the charging module 3 is adapted to the electro-sucker 8 of the hanging rail robot 2. The electro-sucker 8 is used to fix the hanging rail robot 2 for a long time, so as to charge in a relatively stable environment. At the same time, by controlling the size of the electro-sucker 8, the casting core 11 can be extended to the optimal charging position.
[0033] A first guide rod 12 for aligning the hanging rail robot 2 with the charging module 3 is arranged on the outer side wall of the charging module 3. A second guide rod 13 is also arranged on the outer side wall of the charging module 3. The first guide rod 12 is used to guide the hanging rail robot 2 through two extension arms when it first contacts the hanging rail robot 2, to avoid its deviation and impact damage to the casting core 11, causing potential safety hazards.
[0034] Rollable guide wheels 20 are arranged on both side walls of the second guide rod 13. A plurality of damping blocks 14 are detachably installed on the end face of the second guide rod 13 facing the hanging rail robot 2. A receiving groove 22 for receiving the second guide rod 13 is formed on the end face of the charging module 3. A telescopic assembly 19 for pushing out the second guide rod 13 is installed inside the charging module 3. Guide rails 17 for the second guide rod 13 to slide are also arranged on both side walls of the charging module 3.
[0035] The guide rails 17 are used to restrict the sliding direction of the second guide rod 13 and reduce the jitter generated by it. The receiving groove 22 is provided so that the end face of the second guide rod 13 will not interfere with the hanging rail robot 2 when the hanging rail robot 2 and the charging module 3 are charging. The damping blocks 14 are provided to slow down the vibration generated when the two come into contact, and protect the power receiving coil 10 where the hanging rail robot 2 is located and its internal structure from being damaged by impact. The telescopic assembly 19 is provided to push out the second guide rod 13, so as to smoothly push out the hanging rail robot 2, avoid the hanging rail robot 2 from jittering and damaging the casting sleeve 16 when it detaches by itself, and avoid potential safety hazards.
[0036] The utility model can monitor the distance that the core 11 extends into the casting sleeve 16 through the setting of the travel switch 15, so as to control the charging effect. Through the setting of the first guide rod 12 and the second guide rod 13, the core 11 can accurately extend into the casting sleeve 16. By restricting the position of the hanging rail robot 2, the two coils are placed parallel and coaxial, and the magnetic flux between them is the largest. Therefore, the induced electromotive force is also the largest, and the charging efficiency is the highest. The setting of the electro-sucker 8 is used to prevent looseness from occurring when the two are in contact for charging, which may affect the charging effect. The core 11 and the casting sleeve 16 made of potting compound can prevent short circuits and leakage between electrical components, effectively preventing explosions in the mine environment caused by electrical leakage during the charging process, and further improving the safety of the equipment.
[0037] The above are only the preferred embodiments of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the utility model.
