Description

Technical Field

[0001] The utility model relates to the technical field of inspection robots, in particular to a four-wheel drive explosion-proof inspection robot. Background Technique

[0002] In industrial fields such as petrochemical, mining, and other places where flammable and explosive gases or dust exist, in order to improve safety and efficiency and reduce the risks brought by manual inspection, four-wheel drive explosion-proof inspection robots are generally used for inspection work.

[0003] At present, the patent with the patent authorization announcement number CN115741626B discloses an explosion-proof wheeled inspection robot, which includes a chassis, a battery, a circuit control board, a driving mechanism, and wheels. The driving mechanism drives the wheels to rotate. The chassis includes a cabin body and a cover plate. The cover plate covers the opening of the cabin body. The cabin body and the cover plate enclose a cavity, and the battery and the circuit control board are installed in the cavity; a heat dissipation mechanism is installed on the chassis; a convex platform is provided around the opening of the cabin body, the convex platform surrounds the opening for one week, and a groove matching with the convex platform is provided on the cover plate. This kind of explosion-proof wheeled inspection robot has the effect of improving the explosion resistance ability of the robot.

[0004] Although the robot in the above patent has the effect of improving the explosion resistance ability of the robot, there are still certain defects:

[0005] Explosion-proof inspection robots usually work in complex and potentially dangerous environments, such as chemical plants, refineries, etc. The positions and shapes of obstacles in these environments are sometimes dynamically changing, and the robot cannot update its perception model in real time, so it cannot react in time (for example, in a factory, boxes, equipment, or other items may be moved). This results in the pre-stored map information of the robot being no longer accurate, and it is very easy to collide with these temporary obstacles, causing physical damage to the robot. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a four-wheel drive explosion-proof inspection robot to solve the problems raised in the background technique, so that the robot body is not easily directly collided with obstacles, and the probability of damage to the robot body is reduced.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A four-wheel drive explosion-proof inspection robot includes a robot body. Sleeves are hinged on both sides of the robot body. A first motor is fixedly connected to one side of the robot body. The output end of the first motor is fixedly connected to the sleeve. A sliding rod is slidably connected to one end of the sleeve. A connecting block is fixedly connected to the end of the sliding rod away from the sleeve. A collision avoidance block is hinged to the side of the connecting block away from the sleeve. A second motor is fixedly connected to one of the connecting blocks. The output end of the second motor is fixedly connected to the collision avoidance block. The collision avoidance block is conical.

[0008] Further, a chute is provided inside the sleeve. The sliding rod is slidably connected to the chute. A buffer elastic member is provided inside the chute. One end of the buffer elastic member is fixedly connected to the end of the sliding rod, and the other end of the buffer elastic member is fixedly connected to the end of the chute.

[0009] Further, a plug rod is provided inside the chute. One end of the plug rod is fixedly connected to the chute, and a jack matching the plug rod is provided inside the sliding rod.

[0010] Further, guide wheels are rotatably connected to both ends of the anti-collision block on the side away from the sleeve.

[0011] Further, a support wheel is rotatably connected to the middle position of the anti-collision block on the side away from the sleeve.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] For this four-wheel drive explosion-proof inspection robot, an anti-collision block is provided at the front end of the robot main body. If there are temporary obstacles on the forward route of the robot main body, the anti-collision block will contact the obstacles first, avoiding direct collision between the robot main body and the obstacles and causing damage to the robot main body.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Please refer to Figures 1 - 3, A four-wheel drive explosion-proof inspection robot, including a robot main body 1. Sleeves 3 are hinged on both sides of the robot main body 1. A first motor 2 is fixedly connected to one side of the robot main body 1. The output end of the first motor 2 is fixedly connected to the sleeve 3. A sliding rod 5 is slidably connected to one end of the sleeve 3. A connecting block 9 is fixedly connected to the end of the sliding rod 5 away from the sleeve 3. A collision prevention block 10 is hinged to the side of the connecting block 9 away from the sleeve 3. A second motor 11 is fixedly connected to one of the connecting blocks 9. The output end of the second motor 11 is fixedly connected to the collision prevention block 10. The collision prevention block 10 is conical.

[0020] In the four-wheel drive explosion-proof inspection robot of the present utility model, if there are temporary obstacles on the forward route of the robot main body 1, when the robot main body 1 is about to hit an obstacle, the collision prevention block 10 will contact the obstacle first, thus playing a buffering role. In this way, it can avoid the robot main body 1 directly colliding with the obstacle and causing damage to the robot main body 1. At the same time, when the robot main body 1 is walking at a steep slope and there is a possibility of the robot main body 1 tipping forward or backward, the first motor 2 can be driven to drive the sleeve 3 to rotate, so that the collision prevention block 10 is in front of or behind the robot main body 1. Then the second motor 11 is started, and the collision prevention block 10 is driven to rotate a certain angle through the second motor 11, so that the collision prevention block 10 faces the ground. In this way, once the robot main body 1 tips forward or backward, the collision prevention block 10 will abut against the ground, thus avoiding the robot main body 1 directly tipping over and causing damage to the robot main body 1. In addition, the structure of the robot main body 1 in the present utility model is similar to that of an explosion-proof wheeled inspection robot disclosed in the patent with the patent authorization announcement number CN115741626B, so no more elaboration will be made here.

[0021] As Figure 1 、 Figure 2 and Figure 3 shown, a chute 4 is opened inside the sleeve 3. The sliding rod 5 is slidably connected to the chute 4. A buffer elastic member 8 is provided inside the chute 4. One end of the buffer elastic member 8 is fixedly connected to the end of the sliding rod 5, and the other end of the buffer elastic member 8 is fixedly connected to the end of the chute 4.

[0022] Specifically, when the collision prevention block 10 contacts an obstacle, the collision prevention block 10 will move towards the sleeve 3, thereby squeezing the buffer elastic member 8. In this way, it can play a role in buffering the height and give the robot main body 1 sufficient time to stop.

[0023] As Figure 1 、 Figure 2 and Figure 3 shown, a plug rod 7 is provided inside the chute 4. One end of the plug rod 7 is fixedly connected to the chute 4. A jack 6 matching the plug rod 7 is opened inside the sliding rod 5.

[0024] Specifically, the sliding rod 5 is restricted by the insertion rod 7 and the insertion hole 6, making the sliding rod 5 more stable when sliding.

[0025] As Figure 1 , Figure 2 and Figure 3 shown, both ends of the anti-collision block 10 on the side away from the sleeve 3 are rotatably connected with guide wheels 12.

[0026] Specifically, the robot main body 1 is guided by the guide wheels 12. If the obstacle in front of the robot main body 1 is small in size, the guide wheels 12 will guide the robot main body 1 to avoid the front of the robot main body 1 colliding with the obstacle and reducing the probability of damage to the robot main body 1.

[0027] As Figure 1 , Figure 2 and Figure 3 shown, the middle position of the anti-collision block 10 on the side away from the sleeve 3 is rotatably connected with a support wheel 13.

[0028] Specifically, after the second motor 11 drives the anti-collision block 10 to rotate towards the ground, the support wheel 13 will contact the ground to avoid the anti-collision block 10 directly contacting the ground and causing damage to the anti-collision block 10.

[0029] 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.
