Description

Technical Field

[0001] This invention relates to the field of coke oven production equipment technology, and in particular to a coke pusher car sliding track elevation adjustment device. Background Technology

[0002] During coke oven production, coke pushers are typically equipped with a pusher rod device to push the hot coke out of the coke oven from the carbonization chamber. During the pushing operation, the pusher rod needs to extend into the coke oven's carbonization chamber, and it slides within the chamber supported by a sliding shoe device.

[0003] Because coke pushing operations are conducted under high-temperature and heavy-load conditions for extended periods, the sliding track device is prone to wear during use. Wear of the sliding track device causes changes in the elevation of the coke pushing rod, leading to unstable operation, vibration, and other safety hazards. This affects the stability and reliability of the coke pushing operation, necessitating periodic replacement of the sliding track device and increasing production costs.

[0004] Therefore, there is an urgent need for a coke pusher car sliding track elevation adjustment device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a sliding track elevation adjustment device for coke pusher cars, which reduces the replacement frequency and maintenance cost of the sliding track, extends the service life of the sliding track, and thus significantly saves production costs.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The coke pusher car sliding track elevation adjustment device includes:

[0008] The upper sliding shoe has a connecting plate at its bottom, and the connecting plate has hexagonal holes.

[0009] The sliding shoe has two opposing side plates on its top, and each of the two side plates has a first through hole.

[0010] A hexagonal block, wherein the hexagonal block is disposed within the hexagonal hole, and a second through hole is provided at the eccentric position of the hexagonal block;

[0011] A fixed shaft is provided, the connecting plate is inserted between the two side plates, the first through hole and the second through hole are opposite each other, the fixed shaft passes through the second through hole, and the two ends of the fixed shaft pass through the two first through holes respectively.

[0012] Optionally, the center of the second through hole is located on the line connecting the center of the hexagonal block and the midpoint of any side of its outer contour.

[0013] Optionally, the coke pusher car sliding track elevation adjustment device further includes a shaft limiting assembly. The shaft limiting assembly is provided on both sides of the two side plates that are opposite to each other. The shaft limiting assembly is used to restrict the fixed shaft from axially disengaging along the second through hole.

[0014] Optionally, the end of the fixed shaft is provided with a countersunk platform, the countersunk platform including a first limiting surface and a second limiting surface that are perpendicular to each other;

[0015] The shaft limiting assembly includes a limiting plate and a locking member. The bottom end of the limiting plate abuts against the second limiting surface, and the portion of the limiting plate facing the side plate abuts against the first limiting surface. The locking member is used to fix the limiting plate to the side plate.

[0016] Optionally, the locking element is a locking screw.

[0017] Optionally, the coke pusher car slide elevation adjustment device further includes a leveling mechanism, which is used to adjust the levelness of the upper slide.

[0018] Optionally, the leveling mechanism includes:

[0019] A first support arm and a second support arm are respectively disposed on both sides of the upper sliding shoe;

[0020] A first fastener and a second fastener, wherein the first fastener passes through the first support arm and abuts against the sliding shoe, and the second fastener passes through the second support arm and abuts against the sliding shoe.

[0021] Optionally, the first fastener and the second fastener are respectively a first fastening bolt and a second fastening bolt.

[0022] Optionally, the first through hole and the second through hole are respectively clearance-fitted with the fixed shaft.

[0023] Optionally, both the hexagonal block and the fixed shaft are made of metal.

[0024] Beneficial effects:

[0025] The coke pusher car sliding track elevation adjustment device provided by this invention allows for adjustment of the relative height between the upper and lower sliding tracks after the lower sliding track wears down. This is achieved simply by removing the fixed shaft from the first and second through holes, changing the installation direction of the hexagonal block within the hexagonal hole, and then reassembling the fixed shaft. This restores the elevation of the upper sliding track to within the allowable error range, eliminating the need for a complete replacement of the lower sliding track. This compensates for elevation changes caused by lower sliding track wear, improving the stability and safety of the coke pusher car operation. Simultaneously, it reduces the frequency of lower sliding track replacement and maintenance costs, extends the service life of the lower sliding track, and thus significantly saves production costs.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0036] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0039] This embodiment provides a coke pusher car sliding track elevation adjustment device, such as... Figures 1-2 As shown, the coke pusher car sliding track elevation adjustment device includes an upper sliding track 100, a lower sliding track 200, a hexagonal block 300, and a fixed shaft 400. The bottom of the upper sliding track 100 is provided with a connecting plate 110, which has a hexagonal hole. The top of the lower sliding track 200 is provided with two opposing side plates 210, each with a first through hole. The hexagonal block 300 is placed in the hexagonal hole, and a second through hole 310 is provided at the eccentric position of the hexagonal block 300. The connecting plate 110 is inserted between the two side plates 210, with the first through hole and the second through hole 310 opposite each other. The fixed shaft 400 passes through the second through hole 310, and both ends of the fixed shaft 400 pass through the two first through holes respectively. After the lower slide 200 wears out, simply remove the fixed shaft 400 from the first through hole and the second through hole 310, change the installation direction of the hexagonal block 300 in the hexagonal hole, and then reassemble the fixed shaft 400. This allows the relative height between the upper slide 100 and the lower slide 200 to be adjusted, restoring the elevation of the upper slide 100 to within the allowable error range. This compensates for elevation changes caused by wear without requiring a complete replacement of the lower slide 200, improving the stability and safety of the coke pusher operation. Simultaneously, it reduces the replacement frequency and maintenance costs of the lower slide 200, extends its service life, and significantly saves production costs.

[0040] Optionally, such as Figure 1As shown, the center of the second through hole 310 is located on the line connecting the center of the hexagonal block 300 and the midpoint of any side of its hexagonal outer contour, making the distances between the center of the first through hole and each side of the hexagonal outer contour unequal. By changing the installation direction of the hexagonal block 300, six different installation positions can be formed, thereby achieving six different levels of elevation adjustment.

[0041] Optionally, such as Figure 1 and Figure 2 As shown, the coke pusher car sliding track elevation adjustment device also includes a shaft limiting component 500. The two side plates 210 are respectively provided with shaft limiting components 500 on opposite sides to prevent the fixed shaft 400 from moving or falling out along the axial direction of the second through hole 310 under high temperature, vibration and heavy load conditions of the coke pusher car, thereby improving the reliability of the installation of the fixed shaft 400 and the connection stability, thus ensuring the safety and stability of the sliding track elevation adjustment device during long-term operation.

[0042] Optionally, the end of the fixed shaft 400 is provided with a countersunk platform 410, which includes a first limiting surface 411 and a second limiting surface 412 that are perpendicular to each other. The shaft limiting assembly 500 includes a limiting plate 510 and a locking member 520. The bottom end of the limiting plate 510 abuts against the second limiting surface 412, and the portion of the limiting plate 510 facing the side plate 210 abuts against the first limiting surface 411. The locking member 520 is used to fix the limiting plate 510 to the side plate 210. This configuration provides dual limiting for the fixed shaft 400 in both the axial and radial directions, preventing axial movement or rotational loosening of the fixed shaft 400 under high temperature, vibration, and alternating loads, thus improving the positional stability of the fixed shaft 400.

[0043] Optionally, the locking element 520 is a locking screw, which has a simple structure, strong locking force, facilitates the installation and disassembly of the limiting plate 510, and improves the stability and reliability of the connection between the limiting plate 510 and the side plate 210. In this embodiment, each limiting plate 510 is fixed to the side plate 210 by two locking screws, which reduces the assembly difficulty and improves the convenience of maintenance and the reliability of use while ensuring the reliability of fixation.

[0044] Optionally, the coke pusher car sliding track elevation adjustment device also includes a leveling mechanism 600. The leveling mechanism 600 is used to adjust the levelness of the upper sliding track 100 to ensure that the upper sliding track 100 remains in a horizontal state during long-term operation, avoiding unstable operation of the coke pusher rod due to tilting, further improving the operational stability and reliability of the coke pusher car sliding track elevation adjustment device, while also facilitating maintenance and debugging.

[0045] Optionally, such as Figure 1As shown, the leveling mechanism 600 includes a first support arm 610, a second support arm 620, a first fastener 630, and a second fastener 640. The first support arm 610 and the second support arm 620 are respectively disposed on both sides of the upper sliding shoe 100. The first fastener 630 passes through the first support arm 610 and abuts against the lower sliding shoe 200. The second fastener 640 passes through the second support arm 620 and abuts against the lower sliding shoe 200. After the lower sliding shoe 200 wears down, by adjusting the installation direction of the hexagonal block 300 in the hexagonal hole and further adjusting the first fastener 630 and the second fastener 640, the upper sliding shoe 100 can be precisely leveled. This effectively compensates for the tilt of the upper sliding shoe 100 caused by the wear of the lower sliding shoe 200 or the adjustment of the hexagonal block 300, keeping the upper sliding shoe 100 in a horizontal state, thereby ensuring the smooth operation of the coking rod during the coking process.

[0046] Optionally, the first fastener 630 and the second fastener 640 are respectively the first fastening bolt and the second fastening bolt. The first fastening bolt is threaded to the first support arm 610, and the second fastening bolt is threaded to the second support arm 620. By adjusting the length of the first fastening bolt extending out of the first support arm 610 and adjusting the length of the second fastening bolt extending out of the second support arm 620, the horizontal level of the upper slide can be adjusted by 100 degrees.

[0047] Optionally, the first through hole and the second through hole 310 are respectively clearance-fitted with the fixed shaft 400 to ensure that the fixed shaft 400 can be smoothly disassembled and assembled during the adjustment of the sliding shoe elevation, thereby improving the convenience of disassembly and assembly. For example, the diameter of both the second through hole 310 and the first through hole is 120mm, and the diameter of the fixed shaft 400 is 119.8mm. While ensuring connection stability, necessary assembly clearance is reserved for the disassembly and assembly of the fixed shaft 400 and the elevation adjustment operation, further improving the convenience and practicality of the sliding shoe elevation adjustment device.

[0048] In other embodiments, the diameter of the first through hole, the diameter of the second through hole 310, and the diameter of the fixed shaft 400 are not specifically limited, as long as the first through hole and the second through hole 310 can form a clearance fit with the fixed shaft 400 to meet the need for smooth disassembly of the fixed shaft 400.

[0049] Optionally, both the hexagonal block 300 and the fixed shaft 400 are made of metal, which can improve the overall strength and wear resistance of the sliding shoe elevation adjustment device, enhance the stability and service life of the hexagonal block and the fixed shaft 400 under high temperature and heavy load conditions, and at the same time reduce the frequency of maintenance and replacement, significantly saving production costs.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
