Description

Technical Field

[0001] The utility model relates to the technical field of thermal power generation, and particularly relates to a device for quickly replacing the slag rake of a slag scraper. Background Technique

[0002] Slag scraping in a thermal power plant means that at the bottom of the boiler in the thermal power plant, coal is continuously fed by a chain grate. After the coal burns, high-temperature and incandescent slag is produced. These slags need to be cleaned in time, otherwise it will affect the efficiency and safety of the boiler. Therefore, a special slag scraper is needed in the thermal power plant to clean these slags. The slag scraper generally uses a chain scraper and a hoist to scrape the slag out from the bottom of the boiler, or directly uses a slag rake of the slag scraper to fish out the slag and transport it to the slag storage bin. These slags can be used to make building materials such as cement and bricks, or can be used as fertilizers for agriculture.

[0003] For the existing slag scraper, when fishing for slag, due to continuous operation in a high-temperature environment, the slag rake used for fishing for slag is very easy to be damaged or deformed, resulting in a low fishing efficiency. However, when replacing the slag rake, due to the high temperature, the temperature of the slag rake itself is extremely high, and the connection between the slag rake and the device will also be corroded by the high temperature, resulting in a long replacement time and difficulty in replacement.

[0004] The Chinese utility model patent with the patent name of "a device for quickly replacing a slag rake" and the publication number of CN219752346U has been publicly disclosed. This patent includes a slag rake shaft and a bushing. One end of the slag rake shaft is connected to the slag rake, and the other end of the slag rake shaft is inserted into the bushing. The other end of the bushing is connected to the transmission box of the slag scraper. A first square hole is opened at one end of the slag rake shaft close to the bushing, and a corresponding second square hole is opened on the bushing. A main wedge iron is inserted between the first square hole and the second square hole. A third square hole is opened at one end of the main wedge iron, and a sub-wedge iron is inserted into the third square hole. Two round holes are opened at one end of the sub-wedge iron. This device can quickly disassemble the slag rake, shorten the hoisting and installation time of the slag rake, and effectively improve the equipment startup rate.

[0005] Although the above device can avoid quickly replacing the slag rake, manual participation is still required for installation and fixation during the replacement process. In a high-temperature environment, it is very difficult to ensure the safety of the staff. Content of the Utility Model

[0040] Embodiment

[0041] Please refer to Figures 1 - 5 , the present utility model provides a device for quickly replacing the slag rake 5 of a slag scraper, which includes a cross beam 1, a vertical beam structure 2, a vertical rod structure 3, a clamping member 4, a slag rake 5, a support plate member 6, a indexing turntable 7, a positioning structure 8, and a placement rack 9.

[0042] In the prior art, a slag scraper is used to fish out the slag in a thermal power furnace. The slag scraper drives the cross beam 1 to move in a circular motion by setting a rotating structure at one end of the cross beam 1 to change the fishing position. The other end of the cross beam 1 is connected with a vertical beam structure 2, and the vertical beam structure 2 can move vertically to drive the entire slag rake 5 to move up and down, facilitating the insertion into the electric furnace. A vertical rod structure 3 is also provided at the lower part of the vertical beam 23, and the vertical rod structure 3 can also move vertically by itself. The vertical rod 32 in the vertical rod structure 3 is connected with the slag rake 5. When the vertical rod 32 moves, it will drive the slag rake 5 to open and close, thereby realizing the operation of fishing out the slag.

[0043] In this embodiment, in order to realize the quick replacement of the slag rake 5, a quick-disconnect clamping member 4 is provided between the vertical rod structure 3 and the slag rake 5, and a positioning structure 8 and an indexing turntable 7 are provided between the vertical rod structure 3 and the slag rake 5. The positioning structure 8 is connected to the slag rake 5 and fixed on the indexing turntable 7. When the indexing turntable 7 rotates, the slag rake 5 can be driven to rotate through the positioning structure 8, so that the clamping member 4 rotates and disengages from the vertical rod 32, realizing the quick separation of the slag rake 5.

[0044] Furthermore, the vertical beam structure 2 includes a vertical beam frame 21, a first electric cylinder 22, and a vertical beam 23.

[0045] Specifically, the cross beam 1 is fixedly connected to the top of the vertical beam frame 21. Inside the hollow frame of the vertical beam frame 21, a vertical beam 23 is vertically slidably arranged. The first electric cylinder 22 is fixed to the top of the vertical beam frame 21, and the telescopic rod of the first electric cylinder 22 is fixed to the vertical beam 23 to drive the vertical beam 23 to move up and down.

[0046] The vertical rod structure 3 includes a second electric cylinder 31, a vertical rod 32, and a clamping plate 34.

[0047] Specifically, a through hole is vertically arranged at the lower part of the vertical beam 23. The second electric cylinder 31 is located inside the through hole of the vertical beam 23. Inside the through hole, the telescopic rod of the second electric cylinder 31 is fixed to the top end of the vertical rod 32, and the bottom end of the vertical rod 32 extends out of the vertical beam 23.

[0048] A clamping plate 34 is arranged at the bottom end of the vertical rod 32. The clamping plate 34 is in clamping fit with the clamping part 4. A slag rake 5 is fixedly connected below the clamping part 4.

[0049] When the second electric cylinder 31 drives the vertical rod 32 to move up and down, the slag rake 5 connected by the clamping part 4 and the clamping plate 34 also performs the actions of opening and closing.

[0050] Among them, the clamping plate 34 is a waist-shaped plate. The top surface of the clamping part 4 is provided with a waist-shaped groove matching the shape of the clamping plate 34. Inside the clamping part 4, there is a circular chamber communicating with the waist-shaped groove. The circular chamber is located inside the clamping part 4;

[0051] The circular chamber is coaxial with the vertical rod 32 to ensure the accurate matching position of the clamping part 4. The diameter of the circular chamber is larger than the waist-shaped length of the clamping plate 34 to facilitate the rotation of the clamping plate 34 inside it. The height of the circular chamber is the same as the thickness of the clamping plate 34 to ensure that there is no height gap between the clamping plate 34 and the clamping part 4 after the clamping plate 34 enters the circular chamber, and it will not shake during the up and down displacement.

[0052] Preferably, when the clamping plate 34 enters the circular chamber inside the clamping part 4 through the waist-shaped groove of the clamping part 4, rotate the clamping part 4, and the clamping plate 34 can be made not to be in alignment with the waist-shaped groove, and the clamping plate 34 is clamped in the circular chamber, so that the upper and lower corresponding vertical rod structures 3 and the slag rake 5 are connected together.

[0053] In addition, the vertical rod structure 3 further includes a connecting plate 33.

[0054] The connecting plate 33 is fixed to the lower end surface of the vertical beam 23. A indexing turntable 7 is fixedly installed on the bottom surface of the connecting plate 33. The vertical rod 32 slidably passes through the connecting plate 33 and the turntable center of the indexing turntable 7.

[0055] It should be noted that the indexing turntable 7 consists of a cam divider and a turntable. The cam divider drives the turntable to rotate a fixed angle using the worm and worm gear principle, which is prior art and will not be described in detail in the specification.

[0056] A positioning structure 8 is provided on the surface of the indexing turntable 7. The positioning structure 8 includes a third electric cylinder 81 and a positioning sleeve 82.

[0057] Specifically, the head of the telescopic rod of the third electric cylinder 81 is connected with the positioning sleeve 82, and the positioning sleeve 82 moves vertically through the third electric cylinder 81.

[0058] The slag rake 5 includes a positioning column 56, a central shaft 55 and rake claws 54.

[0059] The positioning column 56 is fixed on the central shaft 55 and corresponds to the positioning sleeve 82 up and down. One end of the rake claw 54 is rotatably connected to the central shaft 55, and the other end of the rake claw 54 consists of a plurality of claw plates arranged at intervals.

[0060] Preferably, when the slag rake 5 is clamped and fixed, the clamping plate 34 extends into the clamping member 4, and the positioning sleeve 82 moves vertically through the third electric cylinder 81 and is sleeved with the corresponding positioning column 56 below it. After the clamping plate 34 extends into the circular chamber of the clamping member 4, the indexing turntable 7 rotates 90 degrees, causing the positioning sleeve 82 to rotate and drive the central shaft 55 to rotate. At this time, the rake claw 54 will rotate, making the clamping plate 34 no longer aligned with the waist-shaped groove of the clamping member 4, thus realizing the fixed connection of the slag rake 5.

[0061] In addition, at least one positioning structure 8 and the corresponding positioning column 56 are provided on the indexing turntable 7; the top of the positioning column 56 is spherical, and a circular counterbore is provided inside the positioning sleeve 82 corresponding to the upper part of the positioning column 56. The diameter of the counterbore is the same as the diameter of the top sphere of the positioning column 56; a chamfer is provided at the opening of the circular counterbore of the positioning sleeve 82.

[0062] Through the spherical top of the positioning column 56, even if the positioning column 56 is inclined due to processing problems or the placement problem of the slag rake 5, it can still be aligned and matched with the positioning sleeve 82 through its spherical shape. The chamfer provided at the opening of the positioning sleeve 82 can also provide guidance for the positioning of the positioning column 56, making the positioning smoother.

[0063] Furthermore, support plate members 6 are symmetrically arranged on both sides of the slag rake 5. The support plate members 6 include support inclined plates 61 and limit sliding grooves 62.

[0064] Specifically, both ends of the central shaft 55 are vertically slidably arranged in the limit sliding grooves 62. The limit sliding grooves 62 are located on the lower end surface of the support inclined plate 61, and the upper end of the support inclined plate 61 is fixed on the connecting plate 33. The two ends of the slag rake 5 are supported by the support plate member 6, increasing the bearing points of the slag rake 5.

[0065] Preferably, when the slag rake 5 is used to fish out slag, the third electric cylinder 81 extends, and a downward pressure is applied to the central shaft 55 through the positioning sleeve 82 and the positioning column 56, so that the slag rake 5 is always abutted against the bottom of the limit sliding groove 62 and moves up and down together with the vertical beam 23 connected to the connecting plate 33, preventing it from disengaging from the limit sliding groove 62 during operation.

[0066] When the slag rake 5 needs to be quickly replaced, the vertical rod 32 moves upward and first drives the slag rake 5 to move upward through the clamping member 4, so that the central shaft 55 is removed from the limit sliding groove 62. At this time, the positioning sleeve 82 also moves upward synchronously through the third electric cylinder 81.

[0067] After the central shaft 55 is removed, the indexing turntable 7 starts to rotate, driving the slag rake 5 to rotate through the positioning structure 8, separating the clamping plate 34 from the clamping member 4, and detaching the slag rake 5 and the clamping member 4 fixed thereon from the whole device, facilitating replacement. During the rotation process, the rotation of the central shaft 55 and the rake claws 54 will not interfere with the support plate member 6.

[0068] Furthermore, the slag rake 5 further includes a connecting column 51, a hinge plate 52, a fixing plate 53, a slag cleaning claw 57, a slag cleaning rod 58, and a knocking claw rod 59.

[0069] Among them, the connecting column 51, the hinge plate 52, and the fixing plate 53 form a scissor structure and are connected to the rake claws 54.

[0070] Specifically, the connecting column 51 is fixed to the bottom surface of the clamping member 4. Two hinge plates 52 are arranged on the connecting column 51 and are hinged to one end thereof. The other end of the hinge plate 52 is hinged to the fixing plate 53. The fixing plate 53 is fixedly connected to one end of the rake claw 54 close to the central shaft 55. The rake claws 54 are symmetrically arranged on both sides of the central shaft 55. When the connecting column 51 moves upward following the clamping member 4 and the vertical rod 32, the angle of the hinge plate 52 changes, and one end of the rake claw 54 is pulled through the fixing plate 53, causing the rake claw 54 to rotate on the central shaft 55, opening and closing to achieve slag fishing.

[0071] One end of the rake claw 54 located on the central shaft 55 is also fixedly connected with a slag cleaning claw 57. The slag cleaning claw 57 is located on the rake claw 54 on the other side of the central shaft 55. The claw plate of the slag cleaning claw 57 is arranged in an interleaved manner with the claw plate of the rake claw 54 on the other side.

[0072] When the rake claws 54 on both sides of the central axis 55 close, slag is scooped up. At this time, since the slag cleaning claws 57 swing downward due to the connected rake claws 54, the slag cleaning claws 57 will swing upward through the central axis 55 and swing above the rake claws 54, without being staggeredly arranged with the claw plates of the rake claws 54, and will not interfere with the normal slag scooping work of the rake claws 54.

[0073] When the rake claws 54 on both sides of the central axis 55 open, at this time, since the rake claws 54 swing upward, the slag cleaning claws 57 will swing downward through the central axis 55, so that the claw plates of the slag cleaning claws 57 swing into the gaps between the claw plates of the rake claws 54, being staggeredly arranged with the claw plates of the rake claws 54, and scraping off the slag adhering to the claw plates of the rake claws 54 due to temperature changes, to prevent it from affecting the normal work of the rake claws 54.

[0074] In addition, a slag cleaning rod 58 is provided at one end of the slag cleaning claw 57 far from the central axis 55. The slag cleaning rod 58 connects all the claw plates of the slag cleaning claw 57 and is perpendicular to the plate surface of the claw plates.

[0075] When the rake claws 54 on both sides of the central axis 55 open, the slag cleaning rod 58 on the slag cleaning claw 57 is in sliding contact with the ends of the claw plates of the rake claws 54, so as to scrape off the slag adhering to the heads of the claw plates of the rake claws 54 through the horizontally arranged slag cleaning rod 58.

[0076] In addition, a knocking claw rod 59 is fixedly provided above the slag cleaning claw 57; when the rake claws 54 on both sides of the central axis 55 open, the knocking claw rod 59 above the slag cleaning claw 57 abuts and collides with the upper surface of the rake claws 54, thus vibrating the rake claws 54. When the rake claws 54 put down the scooped slag and then repeat the opening and closing actions, it will cause the knocking claw rod 59 to repeatedly collide with the upper surface of the rake claws 54, so as to shake off the slag on the rake claws 54 that cannot be cleaned by the slag cleaning claws 57.

[0077] Please refer to Figures 6 - 7 , in some embodiments, a placement rack 9 is further provided on the ground. The placement rack 9 includes a bottom plate 91, a support groove rack 92 and a sunk groove 93.

[0078] When replacing the slag rake 5, the replaced old slag rake 5 or the new slag rake 5 to be replaced is temporarily stored on the placement rack 9 to fix the position of the slag rake 5, facilitating the quick positioning and matching of the vertical rod structure 3 and the clamping member 4.

[0079] Specifically, the bottom plate 91 is placed on the ground. Support groove racks 92 are vertically arranged on both sides of the bottom plate 91. The notches of the support groove racks 92 on both sides match the two ends of the central axis 55 to support the central axis 55 in the slag rake 5. A plurality of sunk grooves 93 arranged horizontally are provided on the plate surface of the bottom plate 91. The groove walls of the sunk grooves 93 abut against the lower ends of the rake claws 54, facilitating the abutment against the ends of the rake claws 54 and preventing the situation that the opening angle of the rake claws 54 changes randomly when placed on the ground, resulting in the random change of the height of the entire slag rake 5.

[0080] So far, the embodiments of the present utility model have been described in detail. To avoid obscuring the concept of the present utility model, some details well known in the art have not been described. Those skilled in the art can clearly understand how to implement the technical solutions of the present utility model based on the above description.
