[0020] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0021] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0022] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0023] Please see Figure 1-2 This utility model provides a technical solution: a coal conveying corridor track inspection robot, the inspection robot includes a track 1 set at the upper part; a robot host 2 is suspended at the lower part of the track 1 by rubber wheels 6; a wireless charger 3 is set on the robot host 2; a distance sensor 4 is set on the robot host 2; and a travel sensor 5 is set on the robot host 2.
[0024] Track 1 is positioned at the top to allow for better obstacle avoidance. The robot host 2 reciprocates on track 1 to perform inspection operations. A wireless charger 3 is provided to charge the robot host 2, preventing electrical sparks that could pose a hazard to areas with high fire safety requirements. To achieve active obstacle avoidance, distance sensors are installed at both ends of the robot host 2. One distance sensor 4 is located on each side of the robot host 2. These distance sensors can be infrared, laser, ultrasonic, or other similar types. The travel sensor 5 is used to detect the forward or backward distance of the robot host 2.
[0025] The robot host 2 includes a walking mechanism drive wheel 21 mounted on the upper part to drive its movement; the upper part of the robot host 2 also has a walking mechanism driven wheel 27 arranged parallel to the walking mechanism drive wheel 21; the robot host 2 is equipped with an audible and visual alarm 22 and an external light 23; the robot host 2 is equipped with a battery 24 and a control circuit board 25 inside; the walking mechanism drive wheel 21 is connected to a motor and a reduction gear 26 inside the robot host 2; the robot host 2 is also equipped with an electronic tag detector 28.
[0026] The robot host 2 is powered by an internal battery 24 and provides power output through a motor and a reduction gear 26 to drive the active wheel 21 of the walking mechanism to rotate and move forward or backward. The driven wheel 27 of the walking mechanism is connected to a travel sensor 5 to sense the walking distance. A tag is set at intervals on the track 1, and the real-time position information of the robot host 2 is sensed and detected by the electronic tag detector 28 on the robot host 2.
[0027] An audible and visual alarm 22 and an external light 23 are installed on each side of the robot host 2. If an alarm is required during inspection, the audible and visual alarm 22 can generate different colors and sounds to alert the inspection personnel, and external lights 23 are installed at both the front and rear to assist in observation.
[0028] Working Principle: The coal conveying corridor track inspection robot consists of components such as track 1, robot main unit 2, walking mechanism, control circuit board 25, wireless charger 3, battery 24, distance sensor 4, and stroke sensor 5. The outer shell of the robot main unit 2 is made of metal, providing good mechanical support performance. The overall structure uses a stainless steel frame covered with a metal panel, which effectively reduces the weight of the robot while ensuring the structural strength of the whole machine.
[0029] The top of the robot consists of the driving wheel 21 and the driven wheel 27 of the walking mechanism. The entire robot is suspended on the track 1 by four rubber wheels 6. A wireless charger 3 is located on the side of the robot, used for wireless charging when the robot reaches its destination.
[0030] A distance sensor 4 is designed at both the front and back ends to monitor obstacles on the travel path in real time during movement. When an obstacle is detected, an audible and visual alarm 22 is triggered, and the robot temporarily stops moving. When the obstacle is detected and removed, the robot automatically resumes movement.
[0031] The robot's internal motor and reduction gear 26 transmit power to the drive wheel 21 of the walking mechanism, providing power for the robot's movement. The driven wheel 27 of the walking mechanism has no power output, and its output shaft is connected to the travel sensor 5. The travel sensor 5 detects the robot's current travel distance, speed, and other parameters in real time. By monitoring these parameters, it is possible to determine in real time whether the robot's movement is normal.
[0032] An electronic tag detector 28 is installed on top of the robot near the track 1. An electronic tag is placed at fixed intervals along the track 1. When the robot moves to a specific position, the electronic tag detector 28 senses the tag and reads the positioning information stored within it. This corrects the robot's travel and position information, eliminating travel errors caused by wheel slippage or other factors during movement. The robot has two external lights 23 at both the front and rear, which automatically turn on in low-light conditions to provide automatic supplemental lighting.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
