Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of coke oven inspection, specifically to a coke oven top straight-line temperature inspection robot. Background Technology

[0002] In coking production, the vertical temperature at the top of the coke oven is a key indicator for measuring coke maturity and assessing the thermal condition of the coke oven. Accurate and efficient temperature monitoring is crucial for ensuring coke quality and extending the service life of the coke oven. Currently, most coke oven top temperature monitoring still relies on manual handheld temperature measuring devices. This not only results in a harsh working environment, with high temperatures, dust, and harmful gases seriously threatening the health of operators, but also in low efficiency and poor data accuracy, making it difficult to meet the needs of modern coking production.

[0003] Although some enterprises have introduced inspection robots, existing coke oven roof inspection robots have significant shortcomings in terms of mobility stability and structural robustness. The surface of the oven roof is uneven and contains numerous pipes and equipment. Traditional robot movement mechanisms struggle to adapt to complex terrain, easily experiencing slippage, jamming, or even tipping over, leading to inspection interruptions. Furthermore, unreasonable robot structural design makes component connections prone to loosening and critical structures susceptible to deformation under harsh conditions such as high temperatures and vibrations. This not only affects temperature measurement accuracy but also increases equipment failure rates, and frequent maintenance further reduces inspection efficiency. With the intelligent development of the coking industry, developing a stable and robust coke oven roof straight-line temperature inspection robot has become an urgent need to improve inspection quality and production efficiency. Utility Model Content

[0004] To overcome the aforementioned shortcomings, embodiments of this disclosure provide a straight-line temperature inspection robot for the top of a coke oven, addressing the significant deficiencies in the mobility and structural robustness of existing coke oven top inspection robots. The surface of the oven top is uneven and contains numerous pipes and equipment; traditional robot movement mechanisms struggle to adapt to complex terrain, easily leading to slippage, jamming, or even overturning.

[0005] According to one aspect, at least one embodiment of this disclosure provides a linear temperature inspection robot for the top of a coke oven, comprising:

[0006] A top frame and a housing, the housing being disposed at the bottom of the top frame;

[0007] A movable component, the movable component being disposed between the top frame and the housing;

[0008] A temperature measuring component is disposed at the bottom of the housing;

[0009] The movable component includes a screw, which is fixed inside the bottom of the top frame. The outer shell is movably fitted onto the screw, and an internal threaded drive sleeve is rotatably fitted inside the outer shell. The internal threaded drive sleeve is connected to the screw through a threaded engagement.

[0010] As a further technical solution, an external gear is provided on the outer surface of the internal thread drive sleeve, and a drive gear that is electrically controlled to rotate is provided inside the housing, and the drive gear meshes with the external gear.

[0011] As a further technical solution, the inner two sides of the top frame are provided with sliding grooves, and several movable wheels are rotatably connected to both sides of the outer shell. The movable wheels are supported in the sliding grooves, and both sides of the outer shell are provided with outer sleeves. Cleaning cotton is installed inside the outer sleeves and the cleaning cotton is wrapped around the outer surface of the screw.

[0012] As a further technical solution, the temperature measuring component includes an infrared thermal imager and a single-point infrared thermometer. Both the infrared thermal imager and the single-point infrared thermometer are electrically driven and rotatably connected inside the bottom of the housing. A camera is fixedly connected to the bottom of the housing.

[0013] As a further technical solution, the cross-section of the groove has a T-shaped structure.

[0014] As a further technical solution, the bottom of the top frame has a concave structure, and both the screw and the slide groove are located in the concave part of the bottom of the top frame.

[0015] As a further technical solution, the acquisition camera is installed at the center between the infrared thermal imager and the single-point infrared thermometer, and both the infrared thermal imager and the single-point infrared thermometer can rotate 60° to the left and right respectively.

[0016] As a further technical solution, the acquisition camera is fixedly connected to the bottom of the housing with bolts.

[0017] The beneficial effects of the embodiments disclosed herein are as follows:

[0018] In this disclosure, the moving component achieves stable linear movement of the outer shell through the threaded transmission between the internal threaded drive sleeve and the screw, coupled with the meshing of the drive gear and the external gear.

[0024] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0030] like Figures 1-3 As shown, it illustrates a coke oven top linear temperature inspection robot according to an embodiment of this disclosure, comprising:

[0031] Top frame 1 and outer casing 2, wherein the outer casing 2 is disposed at the bottom of top frame 1;

[0032] A movable component 3 is disposed between the top frame 1 and the outer casing 2;

[0033] Temperature measuring component 4 is disposed at the bottom of the outer casing 2;

[0034] The movable component 3 includes a screw 3-1, which is fixed inside the bottom of the top frame 1. The outer shell 2 is movably fitted onto the screw 3-1. An internal threaded drive sleeve 3-2 is rotatably fitted inside the outer shell 2. The internal threaded drive sleeve 3-2 is threadedly connected to the screw 3-1. An external gear 3-3 is provided on the surface of the internal threaded drive sleeve 3-2. A drive gear 3-4, which is electrically controlled to rotate, is provided inside the outer shell 2. The drive gear 3-4 meshes with the external gear 3-3. Sliding grooves 3-5 are provided on both inner and outer surfaces of the top frame 1. Several moving wheels 3-6 are rotatably connected to both sides of the outer shell 2. The moving wheels 3-6 are supported in the sliding grooves 3-5. An outer sleeve 3-7 is provided on both sides of the outer shell 2. A cleaning cotton 3-8 is installed inside the outer sleeve 3-7 and wraps around the outer surface of the screw 3-1.

[0035] In some examples, the moving component 3 achieves stable linear movement of the housing 2 through the precise engagement of the internal threaded drive sleeve 3-2 and the screw 3-1. When the electrically driven drive gear 3-4 starts to rotate, the meshing external gear 3-3 drives the internal threaded drive sleeve 3-2 to rotate synchronously. Since the internal threaded drive sleeve 3-2 and the screw 3-1 are connected by a threaded engagement, the rotating internal threaded drive sleeve 3-2 will move smoothly along the axial direction of the screw 3-1, thereby driving the housing 2 to move in a straight line. The sliding grooves 3-5 on both sides of the top frame 1 cooperate with the moving wheels 3-6 on both sides of the housing 2. The moving wheels 3-6 roll in the sliding grooves 3-5, which not only provides guidance for the movement of the housing 2, but also enhances the stability during the movement, preventing the housing 2 from deviating or shaking during movement. In addition, the cleaning cotton 3-8 inside the outer casing 3-7 wraps around the outer surface of the screw 3-1. During the movement of the outer casing 2, the cleaning cotton 3-8 can promptly remove dust, coke powder and other impurities attached to the surface of the screw 3-1, preventing impurities from entering the thread structure and affecting the transmission accuracy. This ensures the long-term stable operation of the moving component 3, enabling the inspection robot to move continuously and reliably in the complex environment of the coke oven top.

[0036] like Figures 1-3 As shown in the figure, the temperature measuring component 4 in this embodiment includes an infrared thermal imager 4-1 and a single-point infrared thermometer 4-2. Both the infrared thermal imager 4-1 and the single-point infrared thermometer 4-2 are electrically driven and rotatably connected to the bottom of the housing 2. A data acquisition camera 4-3 is fixedly connected to the bottom of the housing 2.

[0037] In some examples, the temperature sensing component 4 works collaboratively with multiple devices to ensure the stability and accuracy of temperature detection. The infrared thermal imager 4-1 and the single-point infrared thermometer 4-2, driven by an electric motor, can rotate flexibly within the bottom of the outer casing 2, enabling multi-angle and omnidirectional scanning of the coke oven roof's vertical temperature. The infrared thermal imager 4-1 can quickly acquire temperature distribution images over a large area, helping operators intuitively grasp the overall temperature status of the oven roof; the single-point infrared thermometer 4-2 performs precise temperature measurements at key points, providing high-precision temperature data. The two work together to ensure both comprehensive and accurate temperature measurement. Simultaneously, the acquisition camera 4-3, fixed at the bottom of the outer casing 2, can capture real-time images of the oven roof environment, providing auxiliary visual information for temperature measurement. Operators can accurately determine the detection position of the temperature sensing equipment through the camera view, ensuring that the infrared thermal imager 4-1 and the single-point infrared thermometer 4-2 can accurately measure the target area, further improving the stability and reliability of the temperature sensing component 4 and providing accurate and effective temperature data for coke oven thermal state analysis.

[0038] For example, such as Figure 3As shown, the cross-section of the groove 3-5 has a T-shaped structure.

[0039] In some examples, the T-shaped structure allows the pulley to move stably inside, preventing it from falling off during movement. The unique design of the T-shaped groove 3-5 creates a constraint space with upper and lower limits. After the pulley is embedded in it, its rim is firmly held in place by the horizontal edge of the T. Even in the complex environment of high temperature, vibration, and dust on the top of the coke oven, the pulley cannot fall off from the side when the robot encounters bumps or external impacts, ensuring that the movement path is always precise and controllable. At the same time, the T-shaped structure increases the contact area between the pulley and the groove 3-5, dispersing the pressure during robot movement, reducing local wear on the pulley, and extending its service life. Moreover, the stable sliding structure can effectively buffer the impact force from the ground, reducing the data fluctuation of the temperature measuring component 4 caused by vibration, making the inspection robot move more smoothly and reliably on the top of the coke oven, providing a solid guarantee for temperature inspection work.

[0040] For example, such as Figure 3 As shown, the bottom of the top frame 1 has a concave structure, and both the screw 3-1 and the slide groove 3-5 are located in the concave part of the bottom of the top frame 1.

[0041] In some examples, the concave structure conceals the screw 3-1 and slide 3-5 at the bottom, providing a degree of protection. The concave design at the bottom of the top frame 1 cleverly avoids direct corrosion from the harsh external environment for the screw 3-1 and slide 3-5. The coke oven roof is subjected to complex conditions involving high temperatures, dust, and corrosive gases. The concave structure acts as a natural protective shield, reducing the impact of high temperatures on the thread accuracy of the screw 3-1, preventing dust and coke powder from accumulating in the slide 3-5 and hindering pulley operation, and reducing the risk of corrosion to metal components.

[0042] For example, such as Figure 2 As shown, the acquisition camera 4-3 is installed at the center between the infrared thermal imager 4-1 and the single-point infrared thermometer 4-2. Both the infrared thermal imager 4-1 and the single-point infrared thermometer 4-2 can rotate 60° to the left and right respectively.

[0043] In some examples, the acquisition camera 4-3 is installed at the center between the infrared thermal imager 4-1 and the single-point infrared thermometer 4-2, and both the infrared thermal imager 4-1 and the single-point infrared thermometer 4-2 can rotate 60° to the left and right respectively. This layout design achieves efficient coordination between vision and temperature measurement functions. With the acquisition camera 4-3 located in the center, it can capture real-time environmental images of the coke oven roof, providing operators with a clear on-site perspective and assisting in determining whether the detection positions of the infrared thermal imager 4-1 and the single-point infrared thermometer 4-2 are accurate.

[0044] For example, such as Figure 3As shown, the acquisition camera 4-3 is fixedly connected to the bottom of the outer casing 2 by bolts.

[0045] In some examples, the acquisition camera 4-3 is bolted to the bottom of the housing 2, a connection method that balances installation stability with ease of maintenance. When the camera malfunctions or requires cleaning, upgrades, or other maintenance, operators can easily use tools to unscrew the bolts and quickly disassemble the camera, facilitating inspection and replacement. This effectively reduces equipment downtime, ensures the continuous and stable operation of the inspection robot, and guarantees the smooth progress of coke oven top temperature inspection.

[0046] In actual use: The top frame 1 is fixed at a suitable position on the top of the coke oven. The outer shell 2 is movably fitted onto the screw 3-1 at the bottom of the top frame 1. The movable wheels 3-6 on both sides of the outer shell 2 are supported in the T-shaped sliding grooves 3-5 on both sides of the top frame 1. The cleaning cotton 3-8 inside the outer shell 3-7 wraps around the outer surface of the screw 3-1. During startup, the electrically controlled drive gear 3-4 rotates, driving the meshing external gear 3-3 and the internal thread drive sleeve 3-2 to rotate. The internal thread drive sleeve 3-2 moves axially on the screw 3-1 through the threaded engagement, thereby driving the outer shell 2 to move linearly along the screw 3-1. The movable wheels 3-6 roll and guide within the sliding grooves 3-5 to ensure smooth movement. Upon reaching the temperature measurement position, the electric drive infrared thermal imager 4-1 and single-point infrared thermometer 4-2 rotate inside the bottom of the outer casing 2, respectively scanning the temperature of the large area on the top of the furnace and key points. At the same time, the camera 4-3 captures real-time environmental images to assist the operator in accurately determining the temperature measurement position and completing the temperature data collection and recording. During the movement, the cleaning cotton 3-8 promptly removes impurities from the surface of the screw 3-1.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
