Description

Technical Field

[0001] The utility model relates to the technical field of cable detection, in particular to a pipeline flatness detection device with a double encoder for speed measurement. Background Art

[0002] The extrusion method of the cable extruder is to first feed the dried material into the screw conveying device by the dryer, and then the screw conveying device heats the material step by step to a molten state and then extrude it into the annular die. The cable passes through the annular die continuously during the material extrusion process, so that the material is extruded on the cable surface after entering the annular die to form the insulating sheath layer of the cable. However, since the density of the material in the molten state is uneven and changes frequently, and external factors such as temperature also affect the fluidity of the material, the outflow speed of the material will also change in real time, while the speed of the screw under the control of the motor remains constant. This causes the extrusion speed of the material by the screw conveying device to change after the outflow speed of the material changes, resulting in the thickness of the extruded layer formed on the cable surface changing with the change in the extrusion amount, which reduces the surface uniformity of the cable sheath and causes material waste.

[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0025] The embodiment of the present application provides a pipeline flatness detection device with dual encoder speed measurement. The pipeline flatness detection device with dual encoder speed measurement can detect cables through the laser diameter gauge and scraper provided in the detection component, while avoiding the influence of water droplets on the laser diameter gauge, thereby preventing errors in the detection of cables by the laser diameter gauge. Secondly, the encoding wheel can be quickly disassembled through the top block and the fixing rod provided in the clamping component, thereby reducing the stop time of the production line. Moreover, the dual encoding wheel speed measurement can allow the meter weight system to automatically adjust the processing and traction speed to keep the meter weight of the pipe constant.

[0026] The pipeline flatness detection device with dual encoder speed measurement is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0027] The present application is described in detail below in conjunction with the accompanying drawings and specific implementation methods. Figure 1-9 In this embodiment, a pipeline flatness detection device with dual encoder speed measurement includes: a base 1, a connecting column 101 is connected to the top of the base 1, a support column 102 is arranged on one side of the base 1, a mounting block 103 is connected to the top of the support column 102, a connecting plate 104 is connected to the top of the mounting block 103, a detection component, the detection component is arranged between the base 1 and the support column 102, and is used to detect the flatness of the pipeline surface; and a clamping component, the clamping component is arranged between the mounting block 103 and the connecting plate 104, and is used to quickly disassemble the connecting plate 104.

[0028] Example 1

[0029] The detection component includes: a placement block 2 arranged between the base 1 and the support column 102, a laser diameter gauge 201 installed on the top of the placement block 2, a protective plate 202 connected to the inside of the laser diameter gauge 201, a scraper 203 arranged on the side of the protective plate 202 away from the laser diameter gauge 201, a movable groove 204 opened on the side of the protective plate 202 close to the scraper 203, a movable plate 205 connected to the scraper 203 close to the protective plate 202 to cooperate with the protective plate 202, the side of the movable plate 205 away from the scraper 203 extends to the inside of the movable groove 204, a telescopic rod 206 is arranged inside the movable groove 204, the end of the telescopic rod 206 away from the movable groove 204 is connected to the movable plate 205, and a ejection spring 207 is sleeved on the surface of the telescopic rod 206.

[0030] When the laser diameter gauge 201 measures the diameter of the cable, the scraper 203 will first contact the cable. After the scraper 203 contacts the cable, it will scrape off the water drops on the surface of the cable to prevent the water drops on the cable from affecting the laser diameter gauge 201, resulting in the laser diameter gauge 201 being unable to accurately know the diameter of the cable. When the diameter of the cable changes, the scraper 203 will move up and down with the change in the diameter of the cable. The scraper 203 will move with the movable plate 205 when moving. When the movable plate 205 moves, the telescopic rod 206 will move together, so that the extended part of the telescopic rod 206 returns to the inside of the body. At the same time, the movable plate 205 will squeeze the ejection spring 207 when moving, so that the ejection spring 207 becomes an extruded state, allowing the movable plate 205 to move normally inside the movable groove 204, so that the scraper 203 can move up and down, ensuring that the scraper 203 can always fit on the surface of the cable when the cable diameter changes, thereby scraping off water on the cable.

[0031] Example 2

[0032] On the basis of Example 1, a fixing plate 5 is connected to the top of the connecting plate 104, a mounting plate 501 is installed on one side of the fixing plate 5 by bolts, a supporting plate 502 is installed on the side of the mounting plate 501 close to the fixing plate 5 by bolts, a coding wheel 503 is installed on the side of the mounting plate 501 close to the fixing plate 5 and a side of the supporting plate 502 away from the mounting plate 501 through a bearing seat, and a meter weight control system 105 is installed on one side of the connecting column 101.

[0033] There is a certain distance between the two encoding wheels 503 horizontally. When the cable is uneven, the traction speed measured by the front encoding wheel 503 will change, while the traction speed measured by the rear encoding wheel 503 is still stable. At this time, the meter weight system will select the traction speed measured by the rear encoding wheel 503 for calculation. The meter weight control system 105 will read the outer diameter data of the current cable insulation layer measured by the diameter gauge in real time, and compare it with the outer diameter data set by the system, and adjust the extruder host speed or the traction machine speed in real time. For example, at a certain moment, the outer diameter of the cable insulation layer measured by the laser diameter gauge is smaller than the outer diameter of the insulation layer set by the meter weight. At this time, the outer diameter of the cable is thin, and the meter weight control system 105 will immediately increase the host speed to increase the extrusion volume of the extruder after PID calculation to ensure the surface uniformity of the cable sheath.

[0034] Example 3

[0035] On the basis of Example 1, the locking assembly includes: a plurality of positioning rods 3 connected to the top of the mounting block 103, a positioning hole 301 provided on the top of the connecting plate 104 and corresponding to the position of the positioning rod 3, a top block 302 arranged inside the positioning hole 301, a fixing groove 303 provided at the bottom of the top block 302, a clamping plate 304 connected to the fixing groove 303, a movable groove 305 provided on the top of the positioning rod 3, two fixing blocks 306 matching the fixing groove 303 are provided inside the movable groove 305, and the two fixing blocks 306 are provided with a side away from each other. A card slot 307 cooperates with the card plate 304, and sliders 308 are connected to the two side surfaces of the fixed block 306. A sliding slot 309 cooperating with the slider 308 is provided inside the movable slot 305. A reset spring 4 is provided between the two fixed blocks 306. A limiting rod 401 is provided between the two fixed blocks 306. A limiting slot 402 is provided on the side where the two fixed blocks 306 are close to each other. Both ends of the limiting rod 401 extend to the inside of the limiting slot 402 respectively. Both ends of the limiting rod 401 are connected to the limiting plates, and a plurality of rubber limiting rings are provided inside the limiting slot 402.

[0036] When the encoder is to be disassembled, the top block 302 is pressed and the top block 302 will move downward after being pressed. When the top block 302 moves, the two fixing blocks 306 will begin to approach each other. When the two fixing blocks 306 approach each other, they will squeeze the return spring 4, so that the card plate 304 can move out of the card slot 307, thereby releasing the limit fixation of the top block 302 and releasing the pressure on the top block 302. At this time, the connecting plate 104 is grabbed and pulled upward, so that the fixing block 306 can leave the fixing slot 303. At this time, the return spring 4 will begin to recover, so that the fixing blocks 306 begin to move away from each other. When the fixed block 306 moves, the limit plate will gradually leave the limit slot 402 and leave the interior, and the limit plate will contact the rubber limit ring when moving, so as to slow down the rebound speed of the fixed block 306 and prevent the card plate 304 from entering the card slot 307, so that the connecting plate 104 can be removed, so that the encoder can be quickly disassembled and maintenance time can be reduced.

[0037] The specific workflow is:

[0038] After the motor rotates, the cable will enter the base 1 from the roller. After entering the base 1, the cable will be covered with an insulating layer. The cable covered with the insulating layer will move from the base 1 to the cooling water tank to cool the insulating layer. After moving out of the cooling water tank, it will pass through the laser diameter gauge. When the laser diameter gauge 201 measures the diameter of the cable, the scraper 203 will first contact the cable. After the scraper 203 contacts the cable, it will scrape off the water droplets on the surface of the cable to avoid the water droplets on the cable from affecting the laser diameter gauge 201, resulting in the laser diameter gauge 201 being unable to accurately know the diameter of the cable. When the diameter of the cable changes, the scraper 203 will move up and down with the change of the diameter of the cable. When the scraper 203 moves, it will move with the movable plate 205. When the movable plate 205 moves, the telescopic rod 206 will move together, so that the extended part of the telescopic rod 206 returns to the inside of the body.

[0039] At the same time, the movable plate 205 will squeeze the ejection spring 207 when moving, so that the ejection spring 207 becomes squeezed, allowing the movable plate 205 to move normally inside the movable groove 204, so that the scraper 203 can move up and down, ensuring that the scraper 203 can always fit on the surface of the cable when the cable diameter changes, thereby scraping off the water on the cable. The two encoding wheels 503 are horizontally spaced at a certain distance. When the cable is uneven, the traction speed measured by the front encoding wheel 503 will change, while the traction speed measured by the rear encoding wheel 503 is still stable. At this time, the meter weight system will select the traction speed measured by the rear encoding wheel 503 for calculation. The entire process is automatically adjusted and processed by the meter weight system. When the encoder is to be disassembled, press the top block 302. The top block 302 will move downward after being pressed. When moving, the two fixed blocks 306 will begin to approach each other. When the two fixed blocks 306 approach each other, they will squeeze the reset spring 4, so that the card plate 304 can move out of the card slot 307, thereby releasing the limit fixation on the top block 302 and releasing the pressure on the top block 302. At this time, grab the connecting plate 104 and pull it upward so that the fixed block 306 can leave the fixed slot 303. At this time, the reset spring 4 will begin to recover, so that the fixed blocks 306 begin to move away from each other. When the fixed block 306 moves, the limit plate will gradually leave the limit slot 402 and leave the inside. When moving, the limit plate will contact the rubber limit ring, thereby slowing down the rebound speed of the fixed block 306 and preventing the card plate 304 from entering the card slot 307, so that the connecting plate 104 can be removed, so that the encoder can be quickly disassembled and maintenance time can be reduced.
