Description

Technical Field

[0001] The invention relates to the technical field of intelligent robots, in particular to an anti-collision type odor detection robot suitable for different heights. Background Art

[0002] With the continuous development of robot technology, the robot is becoming more and more intelligent, requiring robots to have multiple sensory capabilities to meet the application of various occasions. In recent years, robot olfaction has become a research hotspot. Olfactory function is an indispensable and important part of improving robot intelligence. The essential problem that the robot olfactory system needs to solve is to search for the target odor gas and finally locate the target odor source to complete specific tasks, especially to let the robot replace people to do work related to toxic and harmful gases. The most important and fundamental link in the robot olfactory system is to first let the robot have olfactory function. The robot's olfaction is realized through gas sensors. After the odor gas contacts the gas sensor, the gas sensor will respond and output a certain voltage and current signal. The type and concentration information of the odor gas can be obtained through the output signal of the sensor, realizing the robot's olfactory function. Compared with the robot vision and touch research, in the common gas quality monitoring and detection process of polluted factories, olfactory detection robots are generally required to check the concentration of multiple gas components at the same time.

[0003] The existing olfactory detection manipulator still has certain limitations when in use:

[0004] 1. The heights of the pipelines in the chemical plant vary. Since the height of the sensor platform on the robot cannot be adjusted accordingly, the flexibility of the robot during detection is reduced, making it inconvenient for workers to use.

[0005] 2. The robot needs to move to detect gas, but the pipeline layout in the factory is relatively complicated. Due to the lack of protection during the movement of the robot, it is easy for the sensor on the robot to touch the pipeline facilities, causing certain damage to the gas sensor, resulting in frequent maintenance or even scrapping of the robot. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an anti-collision type odor detection robot suitable for different heights.

[0007] The object of the present invention is achieved through the following technical solutions: an anti-collision type odor detection robot suitable for different heights, comprising a robot base, a fixed column connected to the center position of the top of the robot base, a push rod slidably and horizontally penetrated by the fixed column, the front end of the push rod is fixedly connected to a semi-annular limit column, the rear part of the push rod is sleeved with a first spring, and the first spring is between a fixed block fixedly arranged on the robot base and a handle at the rear end of the push rod, and an adjusting cylinder is slidably sleeved outside the fixed column, a row of limit grooves arranged at intervals up and down are opened on the outer wall of the adjusting cylinder, and a row of limit protrusions arranged on the inner wall of the semi-annular limit column are matched to realize the clamping limit after height adjustment, the top of the adjusting cylinder is fixedly connected to a detection platform, the outside of the detection platform is fixedly installed with a fixed frame, the inside of the fixed frame is sleeved with a second spring, one end of the second spring is fixedly connected to a slider, and the outside of the slider is rotatably connected to a buffer wheel.

[0008] Preferably, a driving wheel is provided at the bottom of the robot base, and a gas sensor, an infrared sensor and an intelligent computer system are provided at the top of the detection platform, so that the manipulator can detect gas according to different smells and is convenient for use in chemical plants.

[0009] Preferably, the fixing frame is fixedly mounted on the detection platform by screws, a slide groove is provided inside the fixing frame, and the sliding block is slidably connected to the outside of the fixing frame through the slide groove.

[0010] Preferably, the fixing frame is divided into two parts, a left part and a right part, and a buffer wheel is installed at each end of each fixing frame.

[0011] Preferably, bosses are fixedly connected to both sides of the exterior of the slider, and the buffer wheel is rotatably connected to the slider via the bosses.

[0012] The present invention has the following advantages:

[0013] 1. By setting a semi-circular limiting column and an adjusting cylinder, when in use, push the push rod forward to disengage the semi-circular limiting column from the adjusting cylinder, slide the detection platform upward, and the adjusting cylinder slides outside the fixed column. When it slides to a suitable position, release the push rod. Under the action of the first spring, the semi-circular limiting column is automatically stuck in the limiting groove of the adjusting cylinder, and the adjusting cylinder is limited, thereby limiting the detection platform. The device is convenient for adjusting the height of the detection platform, and is convenient for gas detection of pipelines at different heights, thereby improving the flexibility of the robot during detection. The operation process is simple and convenient, which is convenient for workers to use, thereby improving the flexibility of the odor detection robot;

[0014] 2. By setting a fixed frame and a buffer wheel, when in use, the buffer wheel is connected to the outside of the fixed frame through a sliding block. When the buffer wheel contacts an object and is subjected to force, the buffer wheel drives the slider to slide inside the fixed frame. Under the action of the second spring, the buffer wheel is used in conjunction with the buffer wheel to reduce the impact force. Under the action of the fixed frame, the buffer wheel can provide buffering protection for multiple surfaces of the detection platform. The device is convenient for anti-collision protection of the detection platform, avoids damage to the sensor due to excessive impact force, and buffers the impact force to a limited extent, which is convenient for the robot to detect in a complex environment and provide anti-collision protection for the sensor, thereby reducing economic losses.
