Description

Technical Field

[0001] This application relates to the field of metallurgical electrical technology, and in particular to an anti-rollover impact swing arm type positioning signal generator. Background Technology

[0002] The steel billets produced by the continuous casting machine are continuously transported to the terminal position via conveyor rollers. Once the steel billet is fully in place, a stable arrival signal needs to be output. The PLC receives the signal and drives the cylinder tilting machine to flip the steel billet to the storage platform. The steel billet arrival signal acquisition device is a key supporting equipment to ensure the continuous operation of the continuous casting production line.

[0003] The existing traditional billet arrival signal acquisition structure mainly consists of a front baffle, an insulating plate, a striking block, insulating components, and an intermediate relay. It relies on the billet impacting and squeezing the striking block, breaking the neutral circuit of the intermediate relay to generate the arrival signal. In actual production, the billet's weight is significant, the roller conveyor speed is stable, and the instantaneous impact force when the billet hits the front baffle and striking block is extremely strong, resulting in several difficult-to-solve on-site defects. First, the insulating plate and insulating components within the structure are non-metallic and easily damaged; repeated and severe impacts can easily cause them to crack or detach, and insulation failure can lead to short circuits and signal malfunctions. Second, long-term high-frequency impacts can cause deformation and warping of the metal striking plate, misalignment of the striking block, and inaccurate identification of the billet's arrival position.

[0004] Secondly, the high temperature and iron oxide dust at the continuous casting site cause dust to accumulate on the sensing end face of the inductive switch and in the gap of the pin rotation. Dust accumulation and jamming of the pin can cause the block to be stuck in its return position. Dust can also cause signal acquisition failure if it blocks the sensing head. The high temperature radiation of the billet can also accelerate the aging of the internal components of the inductive switch, resulting in a short sensor replacement cycle.

[0005] Therefore, this application provides an anti-rollover impact swing arm type positioning signal generator. Summary of the Invention

[0013] Preferably, the surface of the L-shaped bracket is provided with a dust removal component, which is used to clean the sensing end of the inductive proximity switch. The dust removal component includes a vertical mounting plate fixedly disposed on the upper surface of the L-shaped bracket and a support base fixedly disposed on the right side of the buffer sleeve. A compressed air cylinder is fixedly disposed on the upper surface of the support base.

[0014] Preferably, a piston disc is slidably disposed on the inner wall of the compressed air cylinder, and a piston rod is coaxially fixedly connected to the upper surface of the piston disc.

[0019] Preferably, two fixing blocks are symmetrically fixedly installed on the upper surface of the base, and each of the two fixing blocks has a movable shaft rotatably provided on its opposite surface. The opposite ends of the two movable shafts are fixedly connected to the surface of the buffer sleeve.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. The anti-tipping impact swing arm positioning signal generator described in this application abandons the traditional structure of obtaining signals by switching on and off with insulating parts and relays, eliminating the faults of insulation breakage and impact plate deformation caused by the large impact force of the steel billet. It adopts an inductive proximity switch non-contact induction metal sensing block to collect positioning signals, eliminating mechanical contact wear and significantly reducing the frequency of equipment maintenance. The whole adopts a swing arm pin shaft rotation structure, with the front heavy and the rear light impact block, combined with the buffer sleeve and support spring to form elastic support. With the limit structure on both sides, it can effectively prevent the trapezoidal impact block from tipping over, resulting in stronger operation stability and avoiding signal loss and inaccurate steel billet positioning caused by impact block deviation. The surface of the collision baffle is equipped with an arc-shaped high temperature and wear-resistant PU buffer block. The arc structure evenly disperses the impact force of the steel billet. The PU material is high temperature resistant, does not easily melt and stick to the steel billet, and resists repeated impact deformation, extending the service life of the entire metal structure.

[0022] 2. The anti-rollover impact swing arm type positioning signal generating device described in this application forms an elastic buffer assembly through a buffer sleeve, a buffer column and an internal support spring. When the billet impacts, it absorbs the impact load synchronously, reduces the instantaneous impact stress on the support shaft, U-shaped fixed seat and base, and makes the rotating parts such as the base and rotating shaft less prone to cracking and deformation, thus improving the overall impact resistance of the equipment.

[0023] 3. The anti-tipping impact swing arm type positioning signal generator described in this application utilizes the swing of the impact block to drive the buffer column to rise and fall. The extension plate links with the piston of the compressed air cylinder to synchronously complete air compression, and the compressed air cylinder releases high-pressure airflow. The high-pressure airflow blows the sensing end face of the inductive proximity switch through the jet nozzle, and simultaneously blows away the high-temperature iron oxide dust accumulated on the pin shaft and sensing area. The automatic blowing function solves the problem of signal false triggering and signal failure caused by dust covering the inductive switch in the metallurgical site. At the same time, the airflow carries away the radiant heat on the surface of the proximity switch, realizing air cooling, delaying the high-temperature aging of the inductive switch, reducing the workload of manual shutdown for cleaning and sensor replacement, and ensuring the continuous and stable operation of the continuous casting production line.

[0038] The following is in conjunction with the appendix Figure 1 To be continued Figure 8 To further describe this application, an anti-rollover impact swing arm type positioning signal generator includes a base 1, which is an integral steel plate welded frame structure. The upper surface of the base 1 is arranged with a collision component 2, a buffer component 5, a signal generating component 4, and a dust removal component 6.

[0039] The collision component 2 is installed and fixed on the left side of the base 1. The collision component 2 includes a U-shaped fixing seat 201, a support shaft 202, a movable support block 203, a trapezoidal impact block 204, a collision baffle 205, and an arc-shaped buffer block 206. The U-shaped fixing seat 201 is formed by bending thick steel plate and is fixed to the upper surface of the base 1 by bolts at the bottom. The U-shaped fixing seat 201 forms a hollow installation cavity. Through holes are opened on the left and right side walls of the hollow cavity. The support shaft 202 is rotatably inserted inside the through holes. The support shaft 202 can rotate freely inside the U-shaped fixing seat 201. The middle of the outer wall of the support shaft 202 is welded and fixed to the movable support block 203. The movable support block 203 rotates and swings synchronously with the support shaft 202. The top of the movable support block 203 is welded and fixed to the trapezoidal impact block 204. The trapezoidal impact block 204 is wider at the front and narrower at the back, forming a counterweight structure that is heavier at the front and lighter at the back. The left end of the trapezoidal impact block 204 extends outward horizontally, and the end is welded and fixed to the collision baffle 205. The collision baffle 205 is arranged vertically, and the plate surface faces the continuous casting billet conveying roller. When the billet is conveyed along the roller, it will directly impact the front of the collision baffle 205.

[0040] The left side surface of the collision baffle 205 is fixed with an arc-shaped buffer block 206 by countersunk bolts. The arc-shaped buffer block 206 has an overall convex arc structure and is made of wear-resistant and high-temperature resistant PU material. The arc structure can evenly disperse the instantaneous impact force generated by the steel billet impact, avoiding local stress concentration and deformation and cracking of the collision baffle 205. The high-temperature resistant PU material can withstand the heat radiation of the steel billet at 300-600℃, and will not have the problems of ordinary rubber softening, melting and sticking to the steel billet at high temperatures. At the same time, the PU material has high fatigue resistance and buffer performance, and is not easily permanently compressed and deformed by repeated impacts, effectively protecting the main metal components such as the collision baffle 205 and the trapezoidal impact block 204, and significantly extending the maintenance and replacement cycle of the entire collision assembly 2.

[0041] The trapezoidal impact block 204 swings by supporting the shaft 202 and forms an elastic support limit with the tail buffer assembly 5. The front-heavy and rear-light weight distribution of the trapezoidal impact block 204, together with the symmetrically arranged fixing blocks 505 on both sides of the base 1, forms a left and right limit constraint on the buffer sleeve 501. This can effectively prevent the trapezoidal impact block 204 from tilting to the left or right when the billet impacts at high speed, solve the defects of the old-style impact block with unilateral force and skew and signal acquisition failure, and ensure the stability of the impact action and the constant signal acquisition position.

[0042] Two sets of fixing blocks 505 are symmetrically arranged on the upper surface of the base 1 and the lower right position of the U-shaped fixing seat 201. The inner sidewalls of the two fixing blocks 505 are respectively rotatably mounted with movable shafts. The opposite ends of the two movable shafts are fixedly connected to the outer wall of the buffer sleeve 501. The buffer sleeve 501 can rotate slightly by means of the two movable shafts. The buffer sleeve 501 is hollow inside, and a buffer column 502 is slidably assembled inside the cavity. The outer wall of the buffer column 502 is clearance-fitted with the inner wall of the buffer sleeve 501. The buffer column 502 can slide up and down along the vertical direction of the buffer sleeve 501. A support spring 504 is set inside the cavity of the buffer sleeve 501. The bottom end of the support spring 504 is pressed and fixed against the inner bottom wall of the buffer sleeve 501. The top end of the support spring 504 is welded and fixed to the bottom end of the buffer column 502. Under normal conditions, the support spring 504 continuously pushes the buffer column 502 upward to maintain the initial standby position of the buffer column 502 extending upward.

[0043] The top of the buffer column 502 is hinged to the support frame 503. The top of the support frame 503 is hinged to the lower surface of the tail of the trapezoidal impact block 204. When the trapezoidal impact block 204 swings downward, it will press down on the support frame 503, and simultaneously drive the buffer column 502 to compress the support spring 504 downward along the buffer sleeve 501. During the compression process, the support spring 504 absorbs the huge impact load brought by the impact of the steel billet, which greatly reduces the instantaneous impact stress borne by the support shaft 202, the U-shaped fixed seat 201, and the base 1, and avoids cracking, deformation and damage to the rotating shaft and welding position due to long-term impact, thereby improving the impact resistance service life of the entire device.

[0044] A fixed support 602 is welded to the outer right side of the buffer sleeve 501. The compressed air cylinder 603 of the dust removal component 6 is horizontally fixed on the upper surface of the support 602. The buffer sleeve 501 can rotate slightly adaptively by relying on the movable shafts on both sides, which can match the small angular displacement caused by the swing of the trapezoidal impact block 204, and avoid the buffer column 502 and extension plate 607 from getting stuck, so as to ensure that the buffer action and the air pressure compression action operate synchronously and smoothly.

[0045] An L-shaped bracket 401 is fixedly installed on the upper surface of the base 1, below the right end of the trapezoidal bumper 204. The L-shaped bracket 401 is divided into a vertical section and a horizontal section. An inductive proximity switch 402 is fixedly fastened to the top surface of the horizontal section by bolts. The inductive proximity switch 402 is arranged vertically upward with the sensing head facing upward. A metal sensing block 403 is welded to the bottom right end of the trapezoidal bumper 204. The metal sensing block 403 and the sensing head of the inductive proximity switch 402 are directly opposite each other, with a small sensing gap reserved between them, and there is no physical contact.

[0046] This device abandons the old structure of traditional insulation boards, insulation components, and intermediate relays to disconnect the neutral wire and obtain signals. The old structure relies on the impact and compression of steel billets to open and close the circuit with insulation components. The impact force of the steel billets can easily cause the insulation components to break and the impact board to deform. The equipment needs to be shut down for maintenance every week. This solution uses an inductive proximity switch 402 to collect the position signal without contact electromagnetic induction. When the trapezoidal impact block 204 swings downward, the metal sensing block 403 moves down synchronously to the sensing area of ​​the inductive proximity switch 402. The pulse signal is transmitted to the PLC without mechanical contact. There is no mechanical contact wear throughout the process, which eliminates the failure of insulation component wear from the root, greatly reduces the frequency of on-site maintenance, and ensures continuous and stable production of the continuous casting production line.

[0047] The vertical mounting plate 601 is fixed to the outer wall of the vertical section of the L-shaped bracket 401. An air nozzle 610 is embedded on the left side of the vertical mounting plate 601. The nozzle 610 sprays directly at the sensing end face of the inductive proximity switch 402. Together with the dust removal component 6, it can automatically blow away the iron oxide dust accumulated on the surface of the sensing head, avoiding dust covering the sensing surface and causing false signal triggering or signal loss. At the same time, the high-speed airflow carries away the high-temperature radiant heat on the surface of the inductive proximity switch 402, achieving air cooling, delaying the high-temperature aging of the sensor, and extending the service life of the inductive proximity switch 402.

[0048] The dust removal component 6 is driven by the buffer component 5, eliminating the need for external air compressors, solenoid valves, or other external air sources. It fully utilizes the mechanical energy generated by the impact of the steel billet, converting it into high-pressure gas pressure energy, resulting in no additional energy consumption and reducing investment in production line air source equipment and pipeline maintenance costs. The dust removal component 6 includes a vertical mounting plate 601, a support base 602, and a compressed air cylinder 603.

[0049] The compressed air cylinder 603 is horizontally fixed to the top surface of the support base 602. The piston disc 604 is slidably assembled in the internal cavity of the compressed air cylinder 603. The outer wall of the piston disc 604 is sealed and fitted to the inner wall of the compressed air cylinder 603. The piston rod 605 is welded upward on the upper surface of the piston disc 604 in the same direction. The piston rod 605 extends upward through the top of the compressed air cylinder 603. The exposed top of the piston rod 605 is fixed with a movable round block 606. An extension plate 607 is horizontally welded to the left side of the movable round block 606. The left end of the extension plate 607 is welded and fixed to the side wall of the buffer column 502. When the buffer column 502 slides up and down, it will synchronously drive the piston rod 605 and the piston disc 604 to rise and fall synchronously inside the compressed air cylinder 603 through the extension plate 607.

[0050] A return spring 608 is sleeved on the outer wall of the piston rod 605. The bottom end of the return spring 608 is fixed to the top end face of the compressor cylinder 603. The top end of the return spring 608 presses against the lower surface of the movable block 606. In the standby state, the return spring 608 pushes the movable block 606 upward, driving the piston disc 604 to maintain the maximum internal volume of the compressor cylinder 603, allowing external air to continuously fill the cavity. The air inlet end of the compressor cylinder 603 is connected to the air inlet pipe 611. A one-way air inlet valve is installed at the end of the air inlet pipe 611. The one-way air inlet valve only allows external air to enter the compressor cylinder 603. When the piston disc 604 compresses the air, it automatically closes the air inlet channel, locking in the high-pressure gas inside the cavity. The exhaust end of the compressor cylinder 603 is connected to the air guide hose 609. A one-way exhaust valve is installed at the air inlet end of the air guide hose 609, which only opens when the piston disc 604 returns to its original position, releasing the high-pressure airflow in a concentrated manner. During the compression stage, the pipeline is automatically closed to ensure sufficient gas pressure.

[0051] The other end of the air guide hose 609 is connected to the air inlet of the jet nozzle 610. The jet nozzle 610 is embedded on the left side of the vertical mounting plate 601, and the jet nozzle is precisely aligned with the sensing end face of the inductive proximity switch 402. When the buffer column 502 compresses the support spring 504 downward, the extension plate 607 simultaneously presses down the piston plate 604. The air inside the compressed air cylinder 603 is squeezed to form high-pressure gas. After the billet is separated from the collision baffle 205, the support spring 504 and the reset spring 608 simultaneously push the buffer column 502 and the piston plate 604 upward to reset. The high-pressure airflow is delivered to the jet nozzle 610 through the air guide hose 609 and sprayed out at high speed to blow away the iron oxide dust on the surface of the inductive proximity switch 402. At the same time, the airflow carries away the high temperature on the sensor surface, solving the pain points of dust accumulation and high temperature accelerating sensor aging in the metallurgical site. There is no need for manual shutdown for cleaning, which improves the continuity of continuous casting production.

[0052] The working principle of this embodiment is as follows: This device is installed at the billet exit end of the continuous casting roller table. The billet is continuously conveyed forward by the roller table. The end of the billet first contacts the arc-shaped buffer block 206 on the outside of the collision baffle 205. The arc-shaped buffer block 206 buffers and absorbs the impact force of the billet, avoiding instantaneous hard impact deformation of the collision baffle 205. The continuous forward thrust of the billet pushes the collision baffle 205 and the trapezoidal impact block 204 to swing downward around the support shaft 202 as the rotation center. The tail of the trapezoidal impact block 204 presses down on the support frame 503. The support frame 503 drives the buffer column 502 to slide downward along the buffer sleeve 501, simultaneously compressing the internal support spring 504. The support spring 504 absorbs the impact load and buffers the force on the entire device.

[0053] As the buffer column 502 slides downward, the extension plate 607 connected to the side wall simultaneously pulls the movable circular block 606, piston rod 605, and piston disc 604 downward. The piston disc 604 moves downward along the inside of the compressed air cylinder 603, reducing the internal volume of the compressed air cylinder 603 and compressing the internal air. At this time, the one-way inlet valve at the end of the inlet pipe 611 automatically closes, locking the high-pressure gas inside the compressed air cylinder 603. The one-way exhaust valve at the air guide hose 609 is simultaneously closed, and the high-pressure gas is temporarily stored inside the cavity of the compressed air cylinder 603 to complete energy storage.

[0054] During the synchronous downward swing of the trapezoidal impact block 204, the metal sensing block 403 at the bottom right end of the trapezoidal impact block 204 moves down synchronously and approaches the inductive proximity switch 402 installed on the L-shaped bracket 401 below. The two enter the sensing range, and the inductive proximity switch 402 senses the metal sensing block 403 and generates a positioning pulse signal. The pulse signal is transmitted to the on-site PLC control system. After receiving the signal, the PLC controls the cylinder turning machine to start, turning the steel billet that has been positioned on the roller table to the storage platform, thus completing the steel billet positioning signal acquisition and billet turning linkage control.

[0055] After the billet completes the impact, it continues to be conveyed forward along the roller conveyor. The end of the billet disengages from the arc-shaped buffer block 206 and the collision baffle 205, and the impact thrust applied to the trapezoidal impact block 204 disappears. The compressed support spring 504 inside the buffer sleeve 501 rebounds upward, pushing the buffer column 502 to reset upward. The buffer column 502 lifts the trapezoidal impact block 204 upward through the support frame 503. The trapezoidal impact block 204 quickly rotates upward around the support shaft 202 to reset due to its own counterweight structure that is heavier at the front and lighter at the back. The metal sensing block 403 moves upward and away from the inductive proximity switch 402 in sync, and the sensing signal is disconnected, completing the single signal acquisition process.

[0056] When the buffer column 502 resets upward, the extension plate 607 simultaneously pulls the movable block 606 upward. Under the auxiliary thrust of the reset spring 608, the piston rod 605 and piston disc 604 slide upward along the inside of the compressed air cylinder 603, and the volume of the compressed air cylinder 603 expands rapidly. The high-pressure gas stored inside opens the one-way exhaust valve at the end of the air guide hose 609. The high-pressure airflow is delivered to the jet nozzle 610 along the air guide hose 609. The jet nozzle 610 sprays high-speed airflow in a directional direction towards the sensing end face of the inductive proximity switch 402. The airflow washes away the high-temperature iron oxide dust adhering to the surface of the sensing head. At the same time, the flowing air carries away the radiant heat from the surface of the inductive proximity switch 402, completing an automatic dust removal and air cooling operation.
