Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] This invention provides the following technical solutions:

[0032] Example 1

[0033] Combination Figures 1 to 4 A coal mine rescue robot based on a combination of wired and wireless technology includes a robot body 1, a drive mechanism 4 on one side of the robot body 1, a connecting frame 2 on one side of the drive mechanism 4, and a swing mechanism 3 on one side of the connecting frame 2.

[0034] The swing mechanism 3 includes a fixed arm 31, which is fixedly connected to the outside of the connecting frame 2. A long groove 32 is fixedly connected to the side of the fixed arm 31 away from the connecting frame 2. A protrusion 33 is slidably connected to the inner wall of the long groove 32. A rack 34 is fixedly connected to one side of the protrusion 33. A gear 35 meshes with one side of the rack 34. A long shaft 36 is fixedly connected to the inner ring of the gear 35. A swing frame 37 is fixedly connected to the outer wall of the long shaft 36. A short shaft 38 is fixedly connected to the side of the protrusion 33 away from the long groove 32. A groove block 39 is fixedly connected to the side of the short shaft 38 away from the protrusion 33. A push shaft 301 is provided inside the groove block 39. A disc 302 is fixedly connected to the end of the push shaft 301 away from the groove block 39. A support shaft 303 is fixedly connected inside the disc 302. A support frame 304 is fixedly connected to the top of the connecting frame 2.

[0035] Furthermore, the top of the long shaft 36 is rotatably connected to the inside of the support frame 304, and the long shaft 36 passes through the swing frame 37, which facilitates the support of the long shaft 36.

[0036] Furthermore, a long slot is provided on the side of the long slot 32 away from the rack 34, and the short shaft 38 passes through the long slot, so that the short shaft 38 can move through the long slot.

[0037] Furthermore, a short slot is provided on the side of the slot block 39 away from the short shaft 38, and the push shaft 301 is movably connected to the inner wall of the short slot, so that the push shaft 301 can push the slot block 39 to move through the short slot.

[0038] like Figure 5 As shown, in order to achieve flexible adjustment of the robot's internal communication system, the robot body 1 has the following built-in features:

[0039] The wired communication module is used to connect to the PC terminal to import 3D coal mine drawings containing coal mine communication system layout parameters and coal mine excavation parameters; it is also used to export data collected by the robot body.

[0040] The wireless communication module modulation module is used to read 3D coal mine maps and then obtain the wireless communication module docking task for each target point. The module first reads the 3D coal mine maps, then obtains the inspection route of the coal mine rescue robot and the model parameters and location parameters of the communication devices within the coal mine communication system. Next, it queries the corresponding coordinate information of each communication device on the inspection route of the coal mine rescue robot, identifying the target point. Finally, it marks the model parameters of the corresponding communication device and the parameters of the corresponding dockable wireless communication module on the obtained coordinate information, thereby obtaining the corresponding wireless communication module docking task. This module is designed to fully utilize the coal mine communication system to achieve data transmission.

[0041] The wireless communication module group consists of several wireless communication modules and is used to perform wireless communication module docking tasks at fixed points. It communicates with different communication devices (such as dispatching machines, media gateways, etc.) carried in the coal mine communication system, and then outputs data through the different communication devices carried in the coal mine communication system.

[0042] To ensure the accuracy of the collected data, the following was also designed:

[0043] The data correction module is used to correct the position and time parameters of the collected data based on the operational status parameters of the coal mine rescue robot. Specifically, using the inspection route as a template, the operational status parameters (speed, angle, attitude, etc.) of the coal mine rescue robot at each coordinate point are obtained, thereby obtaining the actual position parameters and corresponding time parameters of the coal mine rescue robot, which are then marked on each collected data point.

[0044] Example 2

[0045] See Figures 1 to 4Furthermore, based on Embodiment 1, the drive mechanism 4 further includes a connecting arm 41, which is fixedly connected to the top of the robot body 1. A limiting seat 42 is fixedly connected to the side of the connecting arm 41 away from the robot body 1. A limiting block 44 is inserted into the inner wall of the limiting seat 42. A bolt 43 is provided inside the limiting block 44. A motor 45 is fixedly connected to the inner wall of the connecting frame 2. A worm gear 46 is fixedly connected to the output end of the motor 45. A worm wheel 47 meshes with the outer wall of the worm gear 46. A support block 48 is fixedly connected to the bottom of the inner wall of the connecting frame 2, further improving the synchronization during the operation of the device.

[0046] Furthermore, limit holes are provided on one side of both the limit seat 42 and the limit block 44. Bolts 43 are threaded to the inner wall of the limit holes, and the limit block 44 is fixedly connected to the top of the connecting frame 2, thereby providing limit support for the connecting frame 2.

[0047] Furthermore, the end of the worm 46 away from the motor 45 is rotatably connected to the inner wall of the connecting frame 2, the support shaft 303 passes through the support block 48 and rotates, and the worm wheel 47 is fixedly connected to the outer wall of the support shaft 303, which provides stable support for the support shaft 303 and the worm 46, so that they can transmit power better.

[0048] In actual operation, when this device is used, and it is necessary to clear obstacles on the path of the robot body 1 to move forward or backward, the motor 45 can be started first. The motor 45 drives the support shaft 303 to rotate through the sequential transmission of the worm 46 and the worm wheel 47. The support shaft 303 can drive the disc 302 to rotate. The disc 302 drives the push shaft 301 to make a circular motion along the axis of the support shaft 303. Thus, the push shaft 301 can push the slot block 39 to move. The slot block 39 can drive the rack 34 to rotate through the short shaft 38 and the protrusion 33. The rack 34 drives the meshing gear 35 to rotate. The gear 35 drives the swing frame 37 to swing outward along the axis of the long shaft 36 through the long shaft 36. The support shaft 303 continues to rotate, so that the rack 34 can move back and forth to the left and right. Thus, the obstacles on the path of the robot body 1 to move forward or backward can be cleared by swinging.

[0049] Subsequently, during long-term use, when it is necessary to inspect and maintain the components of the swing mechanism 3 or the drive mechanism 4, the bolt 43 can be unscrewed from the inside of the limit block 44 to remove the limit on the limit block 44. The limit block 44 can then be pulled out from the inner wall of the limit seat 42, thereby disassembling the connecting frame 2 and facilitating the inspection and maintenance of the components by the staff. Similarly, the connecting frame 2 can also be installed.

[0050] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
