Description

Technical Field

[0001] This invention relates to the field of slag removal machine technology, specifically to an external forged chain support roller assembly for a slag removal machine. Background Technology

[0002] When a slag remover is working, it typically uses a chain to drive a scraper, which gradually removes the residue from the slag-water pool, achieving slag-water separation during the removal process. The external return chain roller on the slag remover is generally used to support the chain during the return stroke. The roller body is made of alloy steel, and the rim is heat-treated by quenching, giving it high wear resistance.

[0003] In existing technology, the forging chain is continuously hinged by a thicker outer link and a thinner inner link through an anti-rotation pin. However, when the forging chain of the slag remover rolls on the return roller, the forging chain will vibrate and wobble slightly, causing collisions between the roller and the forging chain. As a result, the forging chain will intermittently jam with the roller during operation. At the same time, the continuous and irregular vibration of the forging chain on the roller can easily cause the anti-rotation pin connecting the outer and inner links to loosen laterally. This makes it impossible to correct the continuously rotating forging chain in time, and in severe cases, it can cause the forging chain to loosen and break, making it difficult to ensure the stable operation of the forging chain for a long time. Summary of the Invention

[0004] The purpose of this invention is to provide an external forged chain support roller assembly for a slag remover, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an external forging chain support roller assembly for a slag remover, comprising an inner groove body disposed on the slag remover and a support roller body located outside the inner groove body. The support roller body has an inner concave cavity in the middle of its outer peripheral side for the forging chain to pass through. The forging chain comprises alternating outer chain links a and inner chain links b, and the outer chain links a and inner chain links b are hinged together by an anti-rotation pin c.

[0006] The inner cavity of the roller body has two parallel annular cavities. The roller body has telescopic pins embedded at equal included angles on the outer periphery of the annular cavities. The annular cavities are fitted with assembly-compatible limiting rings.

[0007] The inner groove body has a mounting seat welded to the outer surface of the support roller body, which is connected to the partition plate. The mounting seat is provided with an adjustment mechanism for squeezing and supporting the limiting ring. The adjustment mechanism can be used to make the limiting ring elastically buffer and laterally limit the movement of the outer link a and the inner link b respectively.

[0008] A squeezing and pushing mechanism is provided on one side of the roller body. The squeezing and pushing mechanism is used to intermittently drive the pressure ring to squeeze and correct the anti-rotation pin c.

[0009] Preferably, the inner tank is fixed with partitions with bearing seats on the outer wall on both sides. The inner tank and the partitions are used to separate the ash water in the slag remover from the roller body and the bearing seat respectively. The roller body has a wheel axle that is connected to the bearing seat through the middle.

[0010] Preferably, the telescopic pin consists of an inner telescopic rod and an outer telescopic sleeve that are telescopically connected to each other. Both the inner telescopic rod and the outer telescopic sleeve have magnetically identical magnets embedded inside. The magnetically identical magnets are used to guide the inner telescopic rod out of the outer telescopic sleeve and abut against the inner wall of the limiting ring. The end of the inner telescopic rod that extends out of the outer telescopic sleeve is embedded with a rotatable ball bearing.

[0011] Preferably, the limiting ring is composed of two semicircular rings spliced ​​together. The first end of the semicircular ring is a protruding part with a toothed surface, and the last end of the semicircular ring is a concave part with a toothed groove. The protruding part and the concave part of the two semicircular rings are engaged and locked together end to end.

[0012] Preferably, the mounting base has symmetrical sliding grooves on both sides;

[0013] The adjusting mechanism includes a sliding sleeve that mates with a sliding groove, a pull rod inserted into the sliding sleeve, and a guide wheel connected to the pull rod via a bearing;

[0014] The guide wheel has flanges on both sides that extend outward and abut against the outer wall of the limiting ring.

[0015] Preferably, a traction arm is connected to the pull rod, and adjacent traction arms are connected by a rotating pin, and a tension spring is connected between the two pull rods that extend through one end of the mounting base.

[0016] Preferably, two interlocking pressure rings are fitted on one side of the roller body, and the two pressure rings are fastened together by bolts at their ends;

[0017] The pressure ring is composed of a semi-circular ring body and a guide block perpendicular to the semi-circular ring body. The surface of the roller body near the pressure ring has a notch for the guide block to slide.

[0018] Preferably, a retaining ring is provided on the outer side of the roller body near the notch, which is installed with the guide block. The side of the retaining ring away from the pressure ring is provided with a slope surface, and a push spring is connected between the roller body and the retaining ring.

[0019] Preferably, the pushing mechanism includes a square bearing sleeve fitted onto the axle, and a push-pull frame slides on the outer side of the square bearing sleeve, the lower end of the push-pull frame engaging with the rotating pin of one of the traction arms.

[0020] Preferably, a cover plate is installed on the top of the push-pull frame, and a pressing rod is connected to the two corners of the cover plate. A rotatable ball bearing is embedded in the front end of the pressing rod near the retaining ring.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: The external forged chain support roller assembly of the slag remover uses a telescopic pin to open the limiting ring, and then uses an adjustment mechanism to elastically support the limiting ring. This allows the moving outer chain link a and inner chain link b to achieve elastic buffering and lateral limiting when they move sequentially to the limiting ring, preventing collisions, jamming, and lateral deviations in the operation of the forged chain. Furthermore, when the limiting ring is squeezed by the outer chain link a, it can drive the extrusion mechanism to squeeze and correct the anti-rotation pin c in the outer chain link a, preventing the anti-rotation pin c from loosening due to lateral vibration after long-term use. This ensures that the forged chain support roller assembly can provide stable operation protection for the forged chain during the return stroke of the slag remover. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-5 This invention provides a technical solution: an external forging chain support roller assembly for a slag remover, comprising an inner tank 1 mounted on the slag remover and a support roller 2 located outside the inner tank 1. The inner tank 1 has partitions with bearing seats 4 fixed on its outer walls on both sides. The inner tank 1 and the partitions are used to separate the ash water inside the slag remover from the support roller 2 and the bearing seats 4, respectively, protecting the support roller 2 and the bearing seats 4 from ash water corrosion and facilitating the long-term normal operation of the support roller. The support roller 2 has a wheel axle 3 connected to the bearing seat 4 at its center, and an inner cavity for the forging chain to pass through is opened at the center of the outer periphery of the support roller 2.

[0034] In this embodiment, two roller bodies 2 are installed on both sides of the axle 3, and the two ends of the axle 3 pass through the partitions on both sides of the inner groove 1 and are connected to the bearing seat 4. Based on this principle, several axles 3 and roller bodies 2 are distributed at equal intervals on the outside of the inner groove 1, so that the forging chain of the slag remover can be supported by rolling return through the concave cavity opened on the outer periphery of the roller body 2.

[0035] Please see Figures 1-3 , Figures 6-8 The forging chain includes alternating outer link a and inner link b, which are hinged together by an anti-rotation pin c. The anti-rotation pin c extends radially through one end of the outer link a and has an anti-disengagement cotter pin. The upper and lower surfaces of the outer link a and inner link b are designed as planes.

[0036] In this embodiment, the outer link a with a larger width and the inner link b with a smaller width are hinged using anti-detachment cotter pins, which allows the forging chain running on the slag remover to make vertical turns and prevents the forging chain from swinging horizontally with large amplitude.

[0037] Please see Figures 3-9 The inner cavity of the roller body 2 has two parallel annular cavities 201. The roller body 2 has a telescopic pin 202 embedded at an equal angle on the outer periphery of the annular cavity 201. The annular cavity 201 is fitted with a limiting ring 203 that can be spliced ​​and assembled. The telescopic pin 202 is composed of an inner telescopic rod and an outer telescopic sleeve that are telescopically connected to each other. The inner telescopic rod and the outer telescopic sleeve are both embedded with magnets of the same magnetic properties. The magnets of the same magnetic properties are used to make the inner telescopic rod extend out of the outer telescopic sleeve and abut against the inner wall of the limiting ring 203. The end of the inner telescopic rod that extends out of the outer telescopic sleeve is embedded with a rotatable ball bearing.

[0038] In this embodiment, a splicable limiting ring 203 is fitted into the annular cavity 201 of the roller body 2. The limiting ring 203 is supported and abutted by telescopic pins 202 distributed at equal angles, so that the limiting ring 203 is elastically supported by the telescopic pins 202 distributed at equal angles. When the limiting ring 203 is squeezed, the limiting ring 203 can move eccentrically with the roller body 2 by squeezing the telescopic pins 202. Since a rotatable ball is embedded in the end of the inner telescopic rod of the telescopic pin 202, the ball makes rolling contact with the inner wall of the limiting ring 203, which facilitates the limiting ring 203 to rotate and relieve pressure when squeezed.

[0039] Please see Figure 9 The limiting ring 203 is composed of two semicircular rings spliced ​​together. The first end of the semicircular ring is a toothed protrusion, and the last end of the semicircular ring is a toothed groove concave part. The protrusion and concave parts of the two semicircular rings are engaged and locked together.

[0040] In this embodiment, when the telescopic pin 202 is embedded into the roller body 2 near the annular cavity 201, the protruding parts and concave parts of the two semicircular rings are engaged end to end, so that the assembled limiting ring 203 can be connected to the annular cavity 201. During subsequent disassembly and replacement, the outer wall gap of the two semicircular rings can be pried to separate the limiting ring 203, thereby facilitating the periodic replacement of the damaged limiting ring 203.

[0041] Please see Figure 1 and Figure 2 The inner tank 1 has a mounting seat 5 welded to the outer surface of the roller body 2, which is opposite to the partition plate. The mounting seat 5 has symmetrical grooves 501 on both sides.

[0042] In this embodiment, one side of the mounting base 5 is embedded in the partition plate, and the mounting base 5 is placed directly below the roller body 2 and welded to the outer surface of the inner groove body 1 to facilitate the positioning and assembly of the mounting base 5.

[0043] Please see Figures 1-4 , Figures 6-8The mounting base 5 is provided with an adjustment mechanism 6 for squeezing and supporting the limiting ring 203. The adjustment mechanism 6 can be used to make the limiting ring 203 elastically buffer and laterally limit the moving outer link a and inner link b respectively. The adjustment mechanism 6 includes a sliding sleeve 601 that docks with the sliding groove 501. A pull rod 602 is inserted into the sliding sleeve 601. A guide wheel 603 is connected to the pull rod 602 through a bearing. The two sides of the guide wheel 603 are provided with flanges that extend outward and abut against the outer wall of the limiting ring 203.

[0044] A traction arm 604 is connected to the pull rod 602, and adjacent traction arms 604 are connected by a rotating pin. A tension spring 605 is connected between the two pull rods 602 that extend through one end of the mounting base 5. A channel for the tension spring 605 to be stretched laterally is reserved in the partition, so that the tension spring 605 can be stretched back and forth.

[0045] In this embodiment, the flanges on both sides of the guide wheel 603 abut against the outer wall of the limiting ring 203. Under the traction of the tension spring 605 on the two pull rods 602, the two pull rods 602 can drive the sliding sleeve 601 to slide along the sliding groove 501 of the mounting seat 5 when they approach each other. At this time, the flanges of the two guide wheels 603 will press the limiting ring 203 upward from both sides, so that the limiting ring 203 moves from bottom to top along the annular cavity 201. At the same time, the limiting ring 203 presses the telescopic pin 202, so that the telescopic pin 202 located below is in a contracted state and the telescopic pin 202 located above is in an extended state.

[0046] When the running forging chain drives the inner link b to move directly above the support roller 2, the two upward-moving limit rings 203 can prevent the inner link b from deviating on both sides, so that the inner link b moves smoothly and is centered above the support roller 2, preventing the forging chain running on the slag remover from lateral deviation when a small amplitude swaying vibration occurs.

[0047] The two limiting rings 203 extending upward into the annular cavity 201 can laterally limit the offset of the inner link b, so that when the forged chain passes through the concave cavity on the roller body 2, the outer link a and the anti-rotation pin c will not collide with the roller body 2, and the forged chain in the return stroke will not cause collision and jamming when it rolls on the roller body 2.

[0048] When the running forging chain moves the outer link a to directly above the support roller 2, the rounded front end of the outer link a will press against the limiting ring 203 exposed above the annular cavity 201. At this time, the limiting ring 203 will move downward and press against the telescopic pin 202, causing the upper telescopic pin 202 to be in a contracted state and the lower telescopic pin 202 to be in an extended state. The downward-moving limiting ring 203 will press against the symmetrically distributed guide wheels 603, causing the two guide wheels 603 to drive the pull rods 602 away from each other. As a result, the two pull rods 602 will stretch the tension spring 605, so that the two guide wheels 603 can buffer the downward-moving limiting ring 203 when they move away from each other. This ensures that the limiting ring 203 can provide elastic buffering for the outer link a during the return stroke, preventing large vibration and wear between the rotating support roller 2 and the forging chain, and ensuring that the forging chain can operate stably.

[0049] Please see Figures 2-5 and Figure 8 Two interlocking pressure rings 204 are fitted on one side of the roller body 2. The two pressure rings 204 are fastened with bolts at their ends. The pressure ring 204 is composed of a semi-circular ring and a guide block perpendicular to the semi-circular ring. A notch is provided on the surface of the roller body 2 near the pressure ring 204 for the guide block to slide. A retaining ring 206 is provided on the outer side of the roller body 2 near the notch and is installed with the guide block. A slope is provided on the side of the retaining ring 206 away from the pressure ring 204. A push spring 205 is connected between the roller body 2 and the retaining ring 206.

[0050] In this embodiment, the semi-circular rings of the two pressure rings 204 are fitted onto the roller body 2, and the guide block perpendicular to the semi-circular ring is inserted into the notch on the surface of the roller body 2. Then, the two pressure rings 204 are fastened together with bolts. Then, the retaining ring 206 is installed with the guide block. Thus, the pressure ring 204 is continuously pressed against the roller body 2 by the compression of the retaining ring 206 by the extrusion spring 205, so as to prevent the pressure ring 204 on the roller body 2 from colliding and interfering with the side of the forging chain.

[0051] Please see Figures 2-8 A squeezing mechanism 7 is provided on one side of the roller body 2. The squeezing mechanism 7 is used to intermittently drive the pressure ring 204 to squeeze and correct the anti-rotation pin c. The squeezing mechanism 7 includes a square bearing sleeve 701 sleeved on the wheel axle 3, and a push-pull frame 702 slides on the outer side of the square bearing sleeve 701. The lower end of the push-pull frame 702 is connected to the rotating pin of one of the traction arms 604. A cover plate 703 is installed on the top of the push-pull frame 702. A squeezing rod 704 is connected to the two corners of the cover plate 703. A rotatable ball is embedded in the front end of the squeezing rod 704 near the retaining ring 206.

[0052] In this embodiment, when the limiting ring 203 presses the guide wheel 603 downward to make the two pull rods 602 move away from each other, the traction arm 604 connecting the pull rods 602 will be gradually straightened from the V-shaped angle state. At this time, the rotating pin located in the middle of the traction arm 604 will move upward, so that one of the upward rotating pins will drive the push-pull frame 702 and the cover plate 703 to move upward, and the push-pull frame 702 will slide upward in a straight line along the square bearing sleeve 701. Thus, the cover plate 703 at the top of the push-pull frame 702 will drive the ball bearing embedded at the front end of the extrusion rod 704 to extrude the slope on one side of the retaining ring 206. Then, the extruded retaining ring 206 will compress the extrusion spring 205, so that the retaining ring 206 moving towards the support roller body 2 can push the pressure ring 204 to move laterally in the direction of the forging chain.

[0053] When the outer link a presses down against the limiting ring 203, the positively laterally moving pressure ring 204 presses against the side of the outer link a. Thus, the pressure ring 204 can press against the tail of the anti-rotation pin c connecting the outer link a and the inner link b, so that the tail of the anti-rotation pin c can be corrected and pressed into the outer link a. This prevents the anti-rotation pin c from loosening due to lateral vibration during long-term use of the forging chain. It not only avoids the side of the forging chain from hitting the roller body 2 due to the lateral vibration of the anti-rotation pin c, but also prevents the anti-detachment cotter pin at the front end of the anti-rotation pin c from repeatedly hitting and breaking against the outer link a, preventing the forging chain from loosening and ensuring that the forging chain can be stably protected during operation.

[0054] Conversely, when the outer link a is far from the limiting ring 203 and the inner link b is close to the limiting ring 203, the outer link a is laterally restricted by the inner concave cavity on the outer periphery of the support roller body 2. This causes the limiting ring 203 to move upward after losing the downward squeezing force. The telescopic pin 202 and the guide wheel 603, which are reset to their respective positions, move upward. This allows the upward-moving limiting ring 203 to laterally restrict the inner link b again. At the same time, the downward-moving rotating pin will drive the traction arm 604 to return from the straightened state to the V-shaped angle state. At this time, the rotating pin located in the middle of the traction arm 604 will drive the push-pull frame 702 and the cover plate 703 to move downward. The extrusion spring 205 will also squeeze the retaining ring 206 to reset, thereby moving the pressure ring 204 away from the forging chain.

[0055] It should be noted that since the inner wall of the limiting ring 203 and the telescopic pin 202, as well as the outer wall of the limiting ring 203 and the guide wheel 603, are in rolling contact, the roller body 2 driven by the forging chain will cause the limiting ring 203 to rotate accordingly. When the limiting ring 203 is not squeezed by the forging chain, the limiting ring 203, which is rolled upward from the bottom sides by the two guide wheels 603, can keep the uppermost edge of the limiting ring 203 exposed in the annular cavity 201, and thus can be continuously used for the lateral limiting of the inner link b and the elastic buffering of the outer link a. The contents not described in detail in this specification are prior art known to those skilled in the art.

[0056] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
