Abstract
Description
Technical Field
[0001] This utility model relates to the field of focus pushing technology, and in particular to a slipper and focus pushing device. Background Technology
[0002] During coke pushing operations, the connecting shaft of the sliding shoe needs to withstand enormous thrust and impact pressure. Influenced by the furnace bottom elevation, the sliding shoe exhibits irregular undulating motion. Friction occurs between the upper and lower base holes of the sliding shoe and the connecting shaft, causing the connecting shaft to rotate circumferentially and accelerating its wear. When wear becomes excessive, the shift in the center of gravity as the coke pusher advances causes it to move into and out of the coke oven at an angle. This alters the tooth tip clearance between the transmission gear and the coke pusher rack, increasing pushing resistance and amplifying the vibration of the coke pusher. Utility Model Content

[0030] Please see Figure 1 and Figure 2 This application provides a sliding shoe 100 for supporting a coke pusher 200. The sliding shoe 100 includes a lower base 110, an upper base 120, a connecting shaft 130, and a fixing assembly 140. The lower base 110 includes a first connecting plate 111 and a second connecting plate 112 disposed opposite to each other, both having a first connecting hole 1111. The upper base 120 has a second connecting hole 1121, which is coaxially disposed with the two first connecting holes 1111. The side of the upper base 120 away from the lower base 110 is used for connection with the coke pusher 200. The connecting shaft 130 passes through the second connecting hole 1121 and the two first connecting holes 1111. The fixing assembly 140 connects the connecting shaft 130 to the first connecting plate 111 or the second connecting plate 112.
[0031] Wear-resistant layers are provided on the inner circumferential surfaces of the two first connecting holes 1111 and the second connecting hole 1121, as well as on the outer circumferential surface of the connecting shaft 130.
[0032] The lower base 110 includes a first connecting plate 111 and a second connecting plate 112 disposed opposite to each other. Both the first connecting plate 111 and the second connecting plate 112 have first connecting holes 1111, and the first connecting holes 1111 on the first connecting plate 111 and the second connecting plate 112 are coaxially arranged. The upper base 120 is located between the first connecting plate 111 and the second connecting plate 112. The upper base 120 has a second connecting hole 1121, which is coaxially arranged with the two first connecting holes 1111. A connecting shaft 130 passes through the second connecting hole 1121 and the two first connecting holes 1111, thereby movably connecting the upper base 120 and the lower base 110. The side of the upper base 120 away from the lower base 110 is used to connect with the coke pusher 200, while the side of the lower base 110 away from the upper base 120 is used to contact the furnace bottom.
[0033] Since the fixing component 140 connects the connecting shaft 130 and the first connecting plate 111 or the second connecting plate 112, when friction occurs between the connecting shaft 130 and the first connecting hole 1111 or the second connecting hole 1121, the fixing component 140 can reduce the degree of circumferential rotation of the connecting shaft 130. Furthermore, since the inner circumferential surfaces of the two first connecting holes 1111 and the second connecting hole 1121, as well as the outer circumferential surface of the connecting shaft 130, are provided with wear-resistant layers, the wear of the connecting shaft 130 can be slowed down, thereby improving the wear condition of the connecting shaft 130 and reducing the coke pushing resistance.
[0034] Specifically, the stepped shaft is forged from high-strength alloy steel and undergoes quenching and tempering treatment and surface hardening treatment to improve the overall mechanical properties and surface hardness of the stepped shaft.
[0035] In some implementations, the wear-resistant layer is made of ceramic or graphite materials.
[0036] The wear-resistant layer can be made of ceramic materials; specifically, it can be a composite of ceramic particles and a metal binder. Alternatively, it can be formed from graphite lubricant. The wear-resistant layer effectively improves the wear resistance of parts and reduces wear at the connection points between holes and shafts.
[0037] In some embodiments, the connecting shaft 130 includes a first shaft body 131 and a second shaft body 132 coaxially connected. The outer diameter of the second shaft body 132 is larger than the outer diameter of the first shaft body 131. The first shaft body 131 is disposed in two second connecting holes 1121 and a first connecting hole 1111. The second shaft body 132 is in contact with the first connecting plate 111.
[0038] During the forward and backward movement of the slipper 100, the connecting shaft 130 will inevitably bear a portion of the axial force. If the fixing component 140 is subjected to stress, deformation and wear over a long period of time, the fixing effect on the connecting shaft 130 will be weakened, and the connecting shaft 130 will easily move axially, causing the slipper 100 to fall off and resulting in an equipment accident.
[0039] Therefore, the connecting shaft 130 includes a first shaft body 131 and a second shaft body 132 coaxially connected. The outer diameter of the second shaft body 132 is larger than the outer diameter of the first shaft body 131, that is, the first shaft body 131 and the second shaft body 132 form a stepped shaft. The first shaft body 131 is disposed in the two second connecting holes 1121 and the first connecting hole 1111. The second shaft body 132 contacts the first connecting plate 111. That is, the first shaft body 131 is used to cooperate with the connecting holes to connect the upper base 120 and the lower base 110. The second shaft body 132 is used for limiting. Under the limiting action of the second shaft body 132, the movement of the connecting shaft 130 in one of the axial directions can be restricted.
[0040] Specifically, the connecting shaft 130 can be made from a high-strength alloy steel billet of suitable specifications, such as 40Cr or 42CrMo. It is then roughly machined into the approximate shape of the connecting shaft 130 using a forging process to ensure uniform density and microstructure, and to eliminate structural defects. The forged connecting shaft 130 is then subjected to a quenching and tempering treatment. It is heated to approximately 850-880℃ and held for 60 minutes, then cooled in a suitable cooling medium for 10 minutes, followed by a high-temperature tempering at 550-680℃ to obtain good comprehensive mechanical properties.
[0041] To improve the surface hardness and wear resistance of the connecting shaft 130, surface hardening treatment is performed on the surface of the connecting shaft 130. The hardening depth is 5mm, the temperature is controlled at 900-1000℃, and the time is about 15 seconds. Then, rapid cooling is performed for 5 seconds to make the surface hardness reach HRC55-60. Considering that the connecting shaft 130 will generate large internal stress after surface hardening, low temperature or medium temperature tempering treatment can be performed if necessary to eliminate the internal stress.
[0042] The connecting shaft 130 can be first subjected to quenching and tempering to lay a good foundation for its mechanical properties, and then surface hardening can be performed to further improve its surface properties. This combination can give full play to the advantages of the two processes, so that the connecting shaft 130 can meet both the overall strength and toughness requirements, as well as the surface wear resistance and fatigue resistance requirements.
[0043] In some embodiments, the fixing component 140 is detachably disposed on the first shaft 131, and the fixing component 140 is located at the end of the first shaft 131 away from the second shaft 132, and the fixing component 140 is connected to the second connecting plate 112.
[0044] The fixing component 140 is disposed on the first shaft 131 and connected to the second connecting plate 112. That is, the fixing component 140 connects the second connecting plate 112 and the connecting shaft 130 to reduce the degree of movement of the connecting shaft 130 during friction and reduce wear. Since the second shaft 132 can restrict the movement of the connecting shaft 130 in one of the axial directions, the fixing component 140 is located at the end of the first shaft 131 away from the second shaft 132. This allows the fixing component 140 to also restrict the movement of the connecting shaft 130 in the other axial direction. That is, even if the fixing component 140 wears and the degree of fixation on the connecting shaft 130 weakens, it can still be used for limiting movement, together with the second shaft 132 and the fixing component 140, to restrict the axial movement of the connecting shaft 130.
[0045] Since the fixing component 140 is detachably disposed on the first shaft 131, when installing the connecting shaft 130, the connecting shaft 130 is first passed through the first connecting hole 1111 and the second connecting hole 1121, and then the fixing component 140 is installed on the connecting shaft 130, and then the fixing component 140 and the second connecting plate 112 are connected.
[0046] Specifically, the fixing assembly 140 includes two fixing plates 141. The first shaft 131 has fixing grooves on both sides, and the two fixing plates 141 are respectively snapped into the two fixing grooves. The fixing plates 141 and the second connecting plate 112 can be connected by bolts and can be welded at the edges to improve the fixing effect of the fixing assembly 140.
[0047] In some embodiments, the slipper 100 further includes a limiting member 150, which is disposed at the end of the first shaft 131 away from the second shaft 132. The fixing assembly 140 is located between the second connecting plate 112 and the limiting member 150. The outer diameter of the limiting member 150 is larger than the outer diameter of the first connecting hole 1111 and the second connecting hole 1121.
[0048] Since the limiting member 150 is located at the end of the first shaft 131 away from the second shaft 132, the outer diameter of the limiting member 150 is larger than the outer diameter of the first connecting hole 1111 and the second connecting hole 1121. That is, the limiting member 150 can also cooperate with the fixing component 140 in the axial direction to further limit the connecting shaft 130, which is equivalent to the last insurance to avoid the axial movement of the connecting shaft 130 as much as possible.
[0049] Specifically, the limiting component 150 includes a limiting bolt 151 and a limiting nut 152. The first shaft 131 has a mounting hole 133, the axis of which is set at an angle to the first shaft 131. The limiting bolt 151 is screwed into the mounting hole 133, and the limiting nut 152 is screwed into the limiting bolt 151 and abuts against the first shaft 131. Of course, the axis of the mounting hole 133 can be set perpendicular to the first shaft 131, thereby achieving the limiting of the limiting bolt 151.
[0050] In some embodiments, the slipper 100 also includes two adjusting members 160 disposed on the upper base 120. The two adjusting members 160 are respectively disposed on both sides of the connecting shaft 130, and the two adjusting members 160 can push the lower base 110 to rotate around the connecting shaft 130.
[0051] The two adjusting members 160 can push the lower base 110 to rotate around the connecting shaft 130, that is, the two adjusting members 160 can push the lower base 110 to rotate around the connecting shaft 130 in different directions to adjust the inlet and outlet posture of the lower base 110.
[0052] Specifically, the adjusting component 160 includes a mounting block 161 and an adjusting bolt 162. The mounting block 161 is disposed on the upper base 120 and has a threaded hole. The adjusting bolt 162 is screwed into the threaded hole, and the adjusting bolt 162 can push the lower base 110 by rotation. That is, the adjusting bolt 162 can move within the threaded hole by rotation and threaded transmission to push the lower base 110, causing the lower base 110 to rotate.
[0053] In some embodiments, a hexagonal slide 170 may also be provided in the second connecting hole 1121, and the connecting shaft 130 passes through the hexagonal slide 170. The inner hole of the hexagonal slide 170 is eccentrically set so that the sliding shoe 100 can be adjusted to form a variety of positions, such as high or low, forward or backward, in the same plane by rotating the hexagonal slide 170.
[0054] Based on the same inventive concept, this application also provides a focus pushing device 10, including a focus pushing rod 200 and the aforementioned slipper 100. The beneficial effects of the focus pushing device 10 provided in this application are the same as those of the slipper 100 described above, and will not be repeated here.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
[0056] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
