Description

Technical Field

[0001] This invention relates to the field of detection device technology, and specifically to a detection device for the slippage of a rotary kiln belt. Background Technology

[0002] Rotary kilns, as key thermal equipment in industries such as cement, metallurgy, and chemicals, directly impact production efficiency and energy consumption levels through their operational stability. The tire (also known as the rolling ring) is a crucial supporting component of the rotary kiln, primarily bearing the weight of the kiln shell and ensuring its smooth rotation through cooperation with support rollers. During long-term operation, due to factors such as differences in thermal expansion, mechanical wear, and changes in lubrication conditions, relative slippage can occur between the tire and the pad beneath the kiln shell. If this slippage exceeds the allowable range, it will lead to abnormal wear between the tire and the pad, increased energy consumption, and even serious consequences such as increased equipment vibration and unplanned shutdowns. Therefore, accurate and timely detection of tire slippage is of paramount importance for ensuring the safe and efficient operation of rotary kilns.

[0003] Currently, rotary kilns generally lack dedicated tire slip detection equipment, and the most commonly used method on site is still manual marking: First, a metal plate with a magnet is attached to the tire, and a scraping tool fixed by magnetic attraction is installed at the corresponding position on the outer wall of the kiln, so that it contacts the surface of the metal plate. After the kiln rotates normally for several revolutions, the scraping tool will leave scratches on the metal plate due to relative slippage. Then, it is manually disassembled and the length of the scratch is measured with a ruler to estimate the slippage.

[0004] However, this detection method has some drawbacks: First, during installation, metal plates and scraping tools must be placed on the rotating kiln body and tire respectively, and continuous contact between the two must be ensured. If the scraping tool is misaligned, the scratches will be distorted, and repeated adjustments are usually required. Second, due to the operating environment of the rotary kiln, manual installation and disassembly are not only inefficient but also pose safety risks. In addition, the scratches obtained by measurement are usually arc-shaped, and on-site measurements are mostly done with a ruler, making it difficult to accurately read the actual slip distance and easily introducing errors. Therefore, technicians have proposed a detection device for the slip of the rotary kiln tire, which aims to simplify the installation of the marking tools, improve measurement accuracy, and ensure the safety and reliability of the detection process. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides a device for detecting the slippage of a rotary kiln belt.

[0006] The technical implementation of this invention is as follows: A rotary kiln tire slippage detection device includes a base frame, which serves as the assembly carrier for the detection device. Specifically, the base frame consists of two parallel metal frames. It also includes a power control module installed inside the base frame, which has a built-in energy storage battery. A push-button switch for controlling the power on / off of the device is provided on one side of the power control module. A guide groove is linearly formed on the lower part of the front frame plate of the base frame. An installation cylinder is slidably connected within the guide groove of the base frame. A scriber cone is installed on the installation cylinder. A marking plate is installed on the base frame near the pointed end of the scriber cone. The scriber cone is used to scribe marks on the marking plate indicating the relative slippage between the kiln body and the tire. The installation cylinder is positioned away from the scriber cone. A guide cylinder is fixedly connected to the side, and a measuring rod is slidably mounted on the guide cylinder. The measuring rod is used to measure the offset between the kiln body and the tire. A first spring is provided between the guide cylinder and the measuring rod. At least two first electromagnets are fixedly mounted on the back frame plate of the base frame. The first electromagnets are used to attract the tire. A second electromagnet is fixedly mounted on the end of the measuring rod away from the first spring. The power control module is electrically connected to the second electromagnet through a power supply line. The second electromagnet is used to attract the kiln body. The power control module is used to simultaneously control the energization state of the first and second electromagnets. A lever is rotatably mounted on the side of the base frame near the push-button switch. The lever facilitates user operation. Magnetic components are provided on the base frame and the lever.

[0007] In a preferred embodiment of the present invention, the magnetic attractor includes a magnetic metal block and a permanent magnet block. The magnetic metal block is fixedly installed on the rod body of the lever near its rotation axis. The permanent magnet block is fixedly disposed on the side of the base frame facing the lever. The permanent magnet block is used to adapt to and attract the magnetic metal block.

[0008] In a preferred embodiment of the present invention, the marking plate has an opening, and a threaded knob is screwed into the opening. The threaded knob is used to securely install the marking plate onto the base frame. The marking plate can be easily removed from or installed onto the base frame by turning the threaded knob.

[0009] In a preferred embodiment of the present invention, a helical rack is slidably mounted on the front frame plate of the base frame, and a second spring is provided between the base frame and the helical rack. A row of helical teeth is provided on the side of the helical rack facing the guide groove. A protrusion is fixedly connected to the guide cylinder, and the protrusion is engaged with the helical tooth groove of the helical rack. When the guide cylinder drives the measuring rod to slide to measure the slippage, the protrusion on the guide cylinder will squeeze the inclined surface of the helical rack, causing the helical rack to compress the second spring to avoid it. Once the protrusion slides past a certain helical tooth, the helical rack resets under the action of the second spring, and its tooth surface will block the protrusion from retracting in the opposite direction, thereby realizing the one-way locking function, ensuring that the measured slippage only increases and does not decrease, reflecting the true cumulative slippage.

[0010] In a preferred embodiment of the present invention, a blocking frame is slidably connected through the base frame, and a protruding ring is fixedly provided on the body of the measuring rod. The blocking frame is used to block the protruding ring. When the base frame is attracted to the end face of the tire, the blocking frame, which is squeezed by the tire, will slide towards the front of the base frame. At this time, the blocking frame will no longer block the protruding ring, and the measuring rod will extend under the action of the first spring until the second electromagnet at the end of the measuring rod is attracted to the side of the kiln body, thereby eliminating the step of the user manually pulling the measuring rod.

[0011] In a preferred embodiment of the present invention, an adjusting screw is rotatably connected inside the mounting cylinder, and the marking cone is slidably mounted inside the mounting cylinder. The adjusting screw and the marking cone are threaded together. The adjusting screw is used to adjust the position of the marking cone inside the mounting cylinder. One end of the adjusting screw is fixedly provided with a diamond-shaped screw head. By turning the screw head, the adjusting screw can be rotated, thereby driving the marking cone to slide inside the mounting cylinder to adjust the marking position of the marking cone and realize multiple markings on the same marking plate.

[0012] In a preferred embodiment of the present invention, a ratchet is fixedly connected to the screw head, and a mounting block is fixedly provided on the side of the base frame away from the ratchet. A wedge block is slidably connected to the mounting block, and the inclined surface of the wedge block faces away from the ratchet. The wedge block is used to automatically rotate the ratchet. After each slip measurement is completed, the user first manually pushes the mounting cylinder towards the wedge block. When the ratchet contacts the wedge block, the wedge block will rotate the ratchet by a certain angle until the ratchet passes the wedge block. When resetting the mounting cylinder in the reverse direction, the helical rack needs to be manually moved first to disengage the helical teeth of the helical rack from the protrusion before the mounting cylinder can be pushed in the reverse direction to reset the measuring rod. During the reset, the tooth surface of the ratchet will contact and push the wedge block to slide past, and the ratchet will no longer rotate. Thus, the user does not need to manually rotate the adjusting screw to adjust the position of the scribe cone.

[0013] In a preferred embodiment of the present invention, a limiting block is fixedly provided on the outer periphery of the wedge block sidewall. The limiting block is used to limit the wedge block on the mounting block to prevent the wedge block from being lost.

[0014] Compared with the prior art, the present invention has the following advantages: 1. This invention uses a power control module to synchronously control the first and second electromagnets, enabling convenient assembly and disassembly of the detection device on the rotary kiln. During the normal rotation of the rotary kiln, the slip displacement of the kiln body and tire is transmitted to the scribe cone through the measuring rod, automatically generating corresponding scratches on the marking plate, thereby effectively measuring the relative offset under working conditions.

[0015] 2. The present invention can ensure that the measuring rod can only move forward in the sliding direction and cannot move backward through the ratchet-type limiting structure composed of the helical rack and the protrusion, effectively preventing vibration or rebound interference and ensuring that the recorded sliding amount is the maximum true value.

[0016] 3. The present invention uses a blocking frame and a convex ring to automatically release the measuring rod when the device is in contact with the tire. The rod pops out and is attracted to the kiln body under the action of the spring. After the test is completed, the entire device can be de-energized and removed simply by moving the lever, which improves the level of automation and the consistency of operation.

[0028] A device for detecting the slippage of a rotary kiln tire, see reference. Figures 1-4As shown, the device includes a base frame 1, which serves as the assembly carrier for the testing device. Specifically, the base frame 1 consists of two parallel metal frames. It also includes a power control module 2 installed inside the base frame 1. The power control module 2 contains a built-in energy storage battery. A push-button switch 21 for controlling the power on / off of the device is located on one side of the power control module 2. A guide groove 3 is linearly formed on the lower part of the front frame plate of the base frame 1. An installation cylinder 4 is slidably connected within the guide groove 3 of the base frame 1. A scriber cone 41 is installed on the installation cylinder 4. A marking plate 12 is installed on the base frame 1 near the pointed end of the scriber cone 41. The scriber cone 41 is used to scribe marks on the marking plate 12 to indicate the relative slippage between the kiln body 100 and the tire 200. A guide cylinder 5 is fixedly connected to the side of the installation cylinder 4 away from the scriber cone 41. A measuring rod is slidably installed on the guide cylinder 5. 6. Measuring rod 6 is used to measure the offset between kiln body 100 and tire 200. A first spring 7 is provided between guide cylinder 5 and measuring rod 6. Two first electromagnets 8 are fixedly provided on the back frame plate of base frame 1. The first electromagnets 8 are used to attract the tire 200. A second electromagnet 9 is fixedly provided at the end of measuring rod 6 away from the first spring 7. Power control module 2 is electrically connected to the second electromagnet 9 through power supply line 91. The second electromagnet 9 is used to attract the kiln body 100. Power control module 2 is used to simultaneously control the power-on state of the first electromagnet 8 and the second electromagnet 9. A lever 10 is rotatably installed on the side of base frame 1 near push button switch 21. The lever 10 facilitates user operation. Magnetic attraction components are provided on base frame 1 and lever 10. The magnetic attraction components are used to attract base frame 1 and lever 10 together.

[0029] See Figure 3 and Figure 4 As shown, the magnetic attractor includes a magnetic metal block 11 and a permanent magnet block 111. The magnetic metal block 11 is fixedly installed on the rod of the lever 10 near its pivot. The permanent magnet block 111 is fixedly installed on the side of the base frame 1 facing the lever 10. The permanent magnet block 111 is used to fit and attract the magnetic metal block 11.

[0030] See Figure 2 and Figure 3 As shown, the marking plate 12 has an opening, and a threaded knob 121 is screwed into the opening of the marking plate 12. The threaded knob 121 is used to securely install the marking plate 12 onto the base frame 1. The marking plate 12 can be easily removed from or installed from the base frame 1 by turning the threaded knob 121.

[0031] See Figure 2 and Figure 5As shown, a helical rack 13 is slidably mounted on the front frame plate of the base frame 1. A second spring 131 is provided between the base frame 1 and the helical rack 13. A row of helical teeth is provided on the side of the helical rack 13 facing the guide groove 3. A protrusion 132 is fixedly connected to the guide cylinder 5. The protrusion 132 is engaged in the helical tooth groove of the helical rack 13. When the guide cylinder 5 drives the measuring rod 6 to slide to measure the slippage, the protrusion 132 on the guide cylinder 5 will squeeze the inclined surface of the helical rack 13, causing the helical rack 13 to compress the second spring 131 to avoid it. Once the protrusion 132 slides past a certain helical tooth, the helical rack 13 is reset under the action of the second spring 131. Its tooth surface will block the protrusion 132 from retracting in the opposite direction, thereby realizing the one-way locking function, ensuring that the measured slippage only increases and does not decrease, reflecting the true cumulative slippage.

[0032] When using this device to detect the slippage of a rotary kiln, the user first rotates the lever 10 towards the base frame 1. When the rotated lever 10 approaches the base frame 1, the magnetic metal block 11 on the lever 10 will be attracted by the permanent magnet block 111. At this time, the lever 10 will press and trigger the button switch 21. The power control module 2 then controls the energy storage battery to supply power to the first electromagnet 8 and the second electromagnet 9, causing the energized first electromagnet 8 and the second electromagnet 9 to generate magnetism. After preparation, first pull the measuring rod 6 outward and compress the first spring 7, then quickly turn the device... When the device is attached to the end face of the tire 200, the first electromagnet 8, which has generated magnetic force, firmly attracts the entire base frame 1 onto the tire 200, so that the main body of the device is stably attracted onto the tire 200. At the same time, the pull rod is released, and under the action of the restoring force of the first spring 7, the measuring rod 6 extends outward until the second electromagnet 9 at the end of the measuring rod 6 is firmly attracted onto the outer circumference of the kiln body 100 of the rotary kiln. This completes the key bridging installation of the device. The main body base frame 1 of the device is connected to the tire 200, and the end of the measuring rod 6 is connected to the kiln body 100.

[0033] Then, wait for the rotary kiln to rotate normally for several revolutions. During this rotation, if relative slippage occurs between the tire 200 and the kiln body 100, it will force the base frame 1 and the measuring rod 6, which are fixed to each other, to move relative to each other. This relative movement forces the measuring rod 6 to drive the guide cylinder 5 and the mounting cylinder 4 connected to it to slide along the guide groove 3 on the base frame 1. At this time, the marking cone 41 installed on the mounting cylinder 4 will then mark on the marking plate 12 on the base frame 1. As the slippage continues, the marking action continues, and finally, the marking is completed on the mark. A straight scratch is left on plate 12. The length of this scratch, i.e., the sliding stroke of mounting cylinder 4, is directly equivalent to the displacement of measuring rod 6, thus effectively reflecting the cumulative slippage of tire 200 relative to kiln body 100. To ensure that the measured value only increases and does not decrease, and to truly reflect the irreversibility of slippage, the base frame 1 is also equipped with a helical rack 13. During the process of slippage causing unidirectional sliding of guide cylinder 5, the protrusion 132 on guide cylinder 5 will squeeze the inclined surface of helical rack 13, causing helical rack 13 to compress the second spring 131 and avoid the protrusion 132. Once the protrusion 132 slides past the inclined teeth of the rack 13, the rack 13 resets under the action of the second spring 131. The vertical tooth surface of the rack 13 then locks the protrusion 132, preventing the etched cone 41 on the guide cylinder 5 and the mounting cylinder 4 from retracting. This ensures that the continuously accumulated slippage is effectively recorded. Finally, when the detection device adsorbed on the rotary kiln returns to the user's installation position, the detection device in the adsorption state will continue to follow the rotary kiln's movement. At this time, the user can directly grasp the lever 10, and the permanent magnet on the lever 10... 111 forces the magnetic metal block 11 on the base frame 1 to separate and demagnetize. At this time, the lever 10 no longer presses the button switch 21, so that the power control module 2 controls the first electromagnet 8 and the second electromagnet 9 to be de-energized and demagnetized at the same time. This makes it easy to quickly remove the entire detection device from the rotary kiln. Finally, by loosening the threaded knob 121, the marking plate 12 is removed from the base frame 1. The scratches marked on the removed marking plate 12 are then measured to obtain the amount of slippage between the kiln body 100 and the tire 200 when the rotary kiln is in the rotating working state.

[0034] See Figure 2 and Figure 5 As shown, a blocking frame 14 is slidably connected through the base frame 1, and a protruding ring 141 is fixedly installed on the body of the measuring rod 6. The blocking frame 14 is used to block the protruding ring 141. When the base frame 1 is attracted to the end face of the tire 200, the blocking frame 14, which is squeezed by the tire 200, will slide towards the front of the base frame 1. At this time, the blocking frame 14 will no longer block the protruding ring 141, and the measuring rod 6 will extend under the action of the first spring 7 until the second electromagnet 9 at the end of the measuring rod 6 is attracted to the side of the kiln body 100, thus saving the user the step of manually pulling the measuring rod 6.

[0035] See Figure 3 and Figure 6As shown, an adjusting screw 15 is rotatably connected inside the mounting cylinder 4. The marking cone 41 is slidably installed inside the mounting cylinder 4. The adjusting screw 15 and the marking cone 41 are threaded together. The adjusting screw 15 is used to adjust the position of the marking cone 41 inside the mounting cylinder 4. A diamond-shaped screw head 151 is fixedly provided at one end of the adjusting screw 15. By turning the screw head 151, the adjusting screw 15 can be rotated, thereby driving the marking cone 41 to slide inside the mounting cylinder 4 to adjust the marking position of the marking cone 41, so as to realize multiple markings on the same marking plate 12.

[0036] See Figures 7-9 As shown, a ratchet 16 is fixedly connected to the screw head 151, and a mounting block 17 is fixedly provided on the side of the base frame 1 away from the ratchet 16. A wedge block 18 is slidably connected to the mounting block 17. The inclined surface of the wedge block 18 is away from the ratchet 16, and the wedge block 18 is used to automatically rotate the ratchet 16.

[0037] See Figure 9 As shown, a limiting block 181 is fixedly provided on the outer periphery of the side wall of the wedge block 18. The limiting block 181 is used to limit the wedge block 18 on the mounting block 17 to prevent the wedge block 18 from being lost.

[0038] To further improve the ease of use of the testing device, a blocking frame 14 is added to the base frame 1. When the base frame 1 is attracted to the end face of the tire 200, the surface of the tire 200 physically pushes back the blocking frame 14, causing the blocking frame 14 to automatically release its restriction on the convex ring 141. The measuring rod 6 is then automatically pushed out by the first spring 7, causing the second electromagnet 9 at the end of the measuring rod 6 to be attracted to the kiln body 100. This eliminates the need for manual pulling of the measuring rod 6, improving the convenience and safety of installing the testing device on the rotary kiln during operation. Furthermore, before the user prepares for the next measurement, they can manually push the mounting cylinder 4 towards the wedge block 18. During this process, the ratchet 16 is wedged... The block 18 blocks the movement and rotates a certain angle. The rotating ratchet 16 drives the adjusting screw 15 to rotate through the screw head 151, so that the marking cone 41 is automatically adjusted to a new marking starting point in the mounting cylinder 4. During the reverse sliding reset of the marking cone 41, the helical rack 13 is manually disengaged to disengage from the protrusion 132. At this time, the back of the teeth of the reset ratchet 16 only slides the wedge block 18 over without rotating, so that the newly adjusted marking position is maintained. On the same marking plate 12, each new measurement can automatically mark a new scratch next to the old record, thus realizing a direct comparison between historical scratch records.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
