[0020] In the embodiments of this application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0021] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0022] Reference Figures 1 to 12 As shown in the figure, this application provides a residue cleaning device 100, including a support assembly 110, a pull rod 120, a motion conversion structure 130, and a loosening cleaning assembly 140.

[0023] The support assembly 110 is used to support the opening 210 of the barrel 200 to be cleaned, and extends partially into the barrel 200.

[0024] The pull rod 120 passes through the support assembly 110 and extends into the material cylinder 200, and the pull rod 120 can move axially under the action of external force. The motion conversion structure 130 is provided in the support assembly 110 and is connected to the pull rod 120 for transmission, and is used to convert the axial movement of the pull rod 120 into rotational motion.

[0025] The loosening and cleaning component 140 is connected to the motion conversion structure 130 and is used to rotate and clean the residue in the material cylinder 200 under the drive of the motion conversion structure 130.

[0026] In practice, the support component 110 is mounted on the opening 210 of the material cylinder 200 to be cleaned, and part of the support component 110 extends into the inside of the material cylinder 200 to achieve quick positioning and assembly of the support component 110 on the material cylinder 200, thereby improving installation efficiency and providing a stable installation reference for the entire residue cleaning device 100.

[0027] The pull rod 120 passes through the support assembly 110 and extends to the residue area at the bottom of the barrel 200, and the pull rod 120 can reciprocate along the axis of the pull rod 120 under the action of an external axial driving force. For example, the external axial driving force of the pull rod 120 can be the force applied by the robot arm or the driving force provided by auxiliary equipment such as a drive motor or a drive cylinder.

[0028] The motion conversion structure 130 is mounted on the support assembly 110 and is in transmission cooperation with the pull rod 120. Its core function is to convert the axial linear motion of the pull rod 120 into the rotational motion required by the loosening cleaning assembly 140 for cleaning operations.

[0029] The loosening and cleaning component 140, as the end effector, rotates synchronously with the motion conversion structure 130 to perform all-round rotational scraping and loosening cleaning of the solidified steel slag clumps and other residues at the bottom of the material cylinder 200. This thoroughly loosens the solidified residue, making it easier to manually remove, dump, or discharge it from the outlet at the bottom of the material cylinder 200. This prevents the residue from accumulating and solidifying at the bottom of the material cylinder 200, which could lead to abnormal operating conditions such as the basket being raised, causing the basket locking to fail, or the motor torque alarm driving the basket to rotate. This ensures the long-term stable operation of the tilting device adapted to the material cylinder 200.

[0030] Reference Figure 6 , Figure 7 and Figure 8As shown, in some embodiments, the pull rod 120 includes at least a first pull rod section 121 and a second pull rod section 122 arranged sequentially along the axial direction. The first pull rod section 121 and the second pull rod section 122 are rotatably engaged. The second pull rod section 122 is located inside the material cylinder 200. The first pull rod section 121 passes through the support assembly 110 and can move along the axial direction of the first pull rod section 121 under the action of external force, thereby driving the second pull rod section 122 to move.

[0031] In practice, the tie rod 120 is divided into a first tie rod section 121 and a second tie rod section 122 arranged sequentially along the axial direction. The two tie rod sections 120 adopt a rotating fit structure, which can realize relative rotational movement. Among them, the first tie rod section 121 passes through the outside of the support assembly 110 and serves as the power input section, which can perform axial linear reciprocating motion under the action of external force. The second tie rod section 122 is located inside the material cylinder 200 and is linked with the first tie rod section 121. It can synchronously follow the first tie rod section 121 to complete axial movement, while also having independent rotational freedom.

[0032] In other words, in this embodiment, the segmented rotational design of the pull rod 120 achieves motion decoupling between power input and power output. The first pull rod segment 121 always maintains pure linear motion without rotational offset, and will not generate torsional torque on the gripped manipulator, effectively protecting the precision manipulator equipment in the hot chamber and avoiding faults such as torque overload and jamming alarms. The second pull rod segment 122 can rotate independently while following the axial movement of the first pull rod segment 121, providing a structural foundation for the subsequent motion conversion structure 130 to achieve linear-to-composite motion, perfectly adapting to the equipment protection requirements of remote automated operation in the hot chamber.

[0033] Reference Figure 6 , Figure 7 , Figure 8 and Figure 11 As shown, in some embodiments, a first bearing assembly 150 is provided between the first tie rod segment 121 and the second tie rod segment 122, and the first bearing assembly 150 is connected to the support assembly 110.

[0034] In specific implementation, a first bearing assembly 150 is provided at the connection position between the first tie rod segment 121 and the second tie rod segment 122, and the first bearing assembly 150 is fixedly connected to the support assembly 110. As a core rotating connector, the first bearing assembly 150 can transmit axial tension and pressure to ensure that the axial movement of the first tie rod segment 121 and the second tie rod segment 122 is completely synchronized. It can also eliminate the circumferential rotation constraint of the second tie rod segment 122, allowing the second tie rod segment 122 to rotate relative to the first tie rod segment 121 simultaneously.

[0035] For example, refer to Figure 6 , Figure 7 , Figure 8 and Figure 11 As shown, the first bearing assembly 150 may include a bearing housing 151 fixed on the support assembly 110, a first rolling bearing 152 disposed inside the bearing housing 151, an end cap 153 disposed at the open end of the bearing housing 151, one end of the first tie rod segment 121 near the second tie rod segment 122 passing through the bearing housing 151 and extending into the bearing housing 151 and connecting with the outer ring of the first rolling bearing 152, and one end of the second tie rod segment 122 near the first tie rod segment 121 passing through the end cap 153 and passing through the inner ring of the first rolling bearing 152, thereby realizing the rotational connection between the two.

[0036] Furthermore, a first locking nut 154 and a first washer 155 can be provided inside the bearing housing 151 to lock the first rolling bearing 152.

[0037] Alternatively, the first tie rod section 121 and the second tie rod section 122 can be rotatably connected by a rotatable joint or a rotatable shaft.

[0038] Reference Figures 7 to 10 As shown, in some embodiments, the motion conversion structure 130 includes a first conversion structure 160 connected to the support component 110 and a second conversion structure 170 connected to the first conversion structure 160.

[0039] The first conversion structure 160 is used to drive the second tie rod section 122 and convert the axial movement of the second tie rod section 122 into a composite motion of axial movement and rotation. The second conversion structure 170 is driven to drive the second tie rod section 122 and the loosening cleaning assembly 140 respectively and converts the composite motion of the second tie rod section 122 into rotational motion and drives the loosening cleaning assembly 140 to rotate.

[0040] In its specific implementation, the motion conversion structure 130 adopts a two-stage conversion design, including a first conversion structure 160 and a second conversion structure 170 that are interconnected, forming a progressive power conversion logic of "linear → compound motion → pure rotational motion". The first conversion structure 160 engages with the second tie rod section 122, converting the single axial linear movement of the second tie rod section 122 into a compound motion of "axial movement + circumferential rotation". The second conversion structure 170 simultaneously engages with the second tie rod section 122 and the end loosening cleaning component 140, filtering and canceling the axial displacement component in the compound motion, retaining only a stable rotational torque, ultimately driving the loosening cleaning component 140 to perform pure axial rotational motion.

[0041] Through the above structural design, rotational power is generated by the axial movement of the tie rod 120, and the axial movement defect of the loosening cleaning component 140 is completely eliminated. This avoids problems such as uneven cleaning, insufficient scraping force, and equipment vibration and displacement caused by the loosening cleaning component 140 rotating and swaying up and down. It ensures that the end loosening cleaning component 140 is always stably attached to the residue layer at the bottom of the material cylinder 200, which greatly improves the loosening and cleaning effect of solidified clumps.

[0042] Reference Figure 8 and Figure 9 As shown, in some embodiments, the first conversion structure 160 includes a connecting cylinder 161 that is connected to the support assembly 110 and the second conversion structure 170 respectively. The side wall of the connecting cylinder 161 is provided with a spiral groove 162 extending circumferentially along the connecting cylinder 161. The outer wall of the second tie rod section 122 is provided with a sliding column 123 that is slidably disposed in the spiral groove 162.

[0043] In a specific implementation, the first conversion structure 160 includes a connecting cylinder 161 fixed between the support component 110 and the second conversion structure 170. The side wall of the connecting cylinder 161 is provided with a spiral groove 162 extending around the periphery. A sliding column 123 is fixedly provided on the outer wall of the second tie rod section 122. The sliding column 123 is slidably embedded in the spiral groove 162 to form a sliding pair structure.

[0044] When the second tie rod section 122 moves axially up and down, the sliding column 123 slides along the trajectory of the spiral groove 162. Under the guidance and constraint of the spiral groove 162, the second tie rod section 122 is forced to rotate circumferentially while moving axially, ultimately generating a composite motion of axial movement and rotation.

[0045] The entire conversion process is free of electrical control, features a simple and reliable structure, is radiation-resistant and high-temperature resistant, and is suitable for harsh working conditions in hot chambers. Furthermore, the precise control of the rotation angle and axial travel distance via the 162 spiral groove trajectory ensures accurate power conversion, stable transmission, and no power loss. It can reliably convert linear driving force into rotational power, providing a reliable power input for subsequent secondary motion conversion.

[0046] Reference Figure 10 As shown, in some embodiments, the second conversion structure 170 includes a housing 171 connected to the first conversion structure 160 and a linkage shaft 172 rotatably disposed within the housing 171; the linkage shaft 172 is provided with an inner spline groove 173, and an outer spline shaft 124 is provided at the end of the second pull rod section 122 away from the first pull rod section 121. The outer spline shaft 124 is slidably disposed within the inner spline groove 173 and the axial length of the inner spline groove 173 is greater than the axial length of the outer spline shaft 124, and the linkage shaft 172 is connected to the loosening cleaning assembly 140.

[0047] In a specific implementation, the second conversion structure 170 includes a housing 171 fixed to one end of the first conversion structure 160 and a linkage shaft 172 rotatably assembled inside the housing 171. The linkage shaft 172 has an internal spline groove 173 of sufficient length inside, and a matching external spline shaft 124 is provided on the lower outer wall of the second pull rod section 122. The external spline shaft 124 is slidably embedded in the internal spline groove 173 to form a sliding transmission pair of the external spline shaft 124. At the same time, the lower end of the linkage shaft 172 is fixedly connected to the loosening cleaning component 140.

[0048] When the first tie rod section 121 drives the second tie rod section 122 to move axially, the axial displacement of the second tie rod section 122 can be offset by the sliding of the external spline shaft 124. That is, the movement stroke is offset by the sliding of the external spline shaft 124 in the internal spline groove 173, so that the axial movement of the second tie rod section 122 will not be transmitted to the linkage shaft 172. The rotational torque can be completely transmitted to the linkage shaft 172 through the meshing of the external spline shaft 124 and the internal spline groove 173. Finally, the pure rotation operation of the loosening cleaning component 140 is realized, which completely solves the problem of the loosening cleaning component 140 moving and the cleaning failure, and ensures that the cleaning operation is stable, uniform and efficient.

[0049] Reference Figure 10 As shown, in some embodiments, a second bearing assembly 180 is provided between the linkage shaft 172 and the housing 171 to enable the linkage shaft 172 to rotate freely relative to the fixed housing 171.

[0050] For example, a first connecting flange is provided at one end of the outer shell 171 near the first conversion structure 160, a second connecting flange is provided at one end of the connecting cylinder 161 near the outer shell 171, and an end cap 184 is provided between the first connecting flange and the second connecting flange. The three are connected in sequence by a through fastener.

[0051] The second bearing assembly 180 includes a second rolling bearing 181, the outer ring of the second rolling bearing 181 is fixed relative to the outer shell 171, and the linkage shaft 172 passes through the inner ring of the second rolling bearing 181 and can be fixed by the second locking nut 182 and the second washer 183.

[0052] Alternatively, the linkage shaft 172 and the housing 171 can be rotated together by means of an annular groove and a slider.

[0053] Reference Figure 3 As shown, a tapered connecting sleeve 190 is provided between the outer shell 171 and the first conversion structure 160.

[0054] To facilitate the machining of the spiral groove 162, the outer diameter of the connecting cylinder 161 is larger than the outer diameter of the outer shell 171. To facilitate a reliable connection between the outer shell 171 and the connecting cylinder 161, a tapered connecting sleeve 190 is provided between the two for connection.

[0055] Reference Figure 4 , Figure 10 and Figure 12 As shown, in some embodiments, the residue cleaning device 100 further includes a softening medium component 300, and the loosening cleaning component 140 is provided with a spray nozzle 145. The softening medium component 300 is connected to the spray nozzle 145 to output a softening medium to the residue in the material cylinder 200 to soften the residue.

[0056] In practice, a softening medium component 300 is added, and a spray nozzle 145 is provided on the surface of the loosening and cleaning component 140. The softening medium component 300 is connected to the spray nozzle 145, so that the softening medium can be continuously sprayed onto the solidified residue at the bottom of the material cylinder 200, so that the loosening and cleaning component 140 can loosen and clean the residue.

[0057] For example, the softening medium can be high-temperature steam, water, or other media that can soften and loosen the residue. The specific softening medium is not limited to the examples mentioned above in this embodiment.

[0058] Reference Figure 4 , Figure 10 and Figure 12 As shown, in some embodiments, the loosening cleaning assembly 140 includes a hollow shaft 141 and a cleaning head 142 disposed on the side of the hollow shaft 141 away from the motion conversion structure 130, with a spray nozzle 145 disposed on the cleaning head 142 and communicating with the hollow shaft 141.

[0059] The softening medium assembly 300 includes an input interface 310, a delivery pipe 320, and a connecting sleeve 330 sleeved on the outer wall of the hollow shaft 141. The input interface 310 is located on the support assembly 110 and is used to allow external softening medium to pass through. One end of the delivery pipe 320 is connected to the input interface 310, and the other end of the delivery pipe 320 is connected to the connecting sleeve 330. The connecting sleeve 330 is connected to the hollow shaft 141.

[0060] The cleaning head 142 includes a support plate 143 and a plurality of arrayed support columns 144 disposed on the side of the support plate 143 away from the motion conversion structure 130, with cleaning components 146 inserted on the support columns 144.

[0061] In specific implementation, the softening medium assembly 300 includes an input interface 310 on the support assembly 110, a delivery pipe 320 connecting the pipeline, and a connecting sleeve 330 sleeved on the outside of the hollow shaft 141. The external softening medium is input through the input interface 310, conducted through the delivery pipe 320 and the connecting sleeve 330 to the hollow shaft 141, and finally sprayed out from the spray nozzle 145 of the cleaning head 142. This allows the softening medium to heat and soften, deliquesce and loosen hardened residues, significantly reducing the hardness and adhesion of the solidified residues. Combined with the rotating cleaning action of the loosening cleaning assembly 140, it avoids the problem that simple mechanical scraping is insufficient to clean hardened lumps, greatly improves residue cleaning efficiency, thoroughly removes stubborn solidified residues, and solves the problem of the suspended platform being raised at its root.

[0062] Reference Figure 12 As shown, the cleaning head 142 includes a support plate 143 and an array of support columns 144 distributed at the bottom of the support plate 143. Each support column 144 can be plugged into and installed with a special cleaning component 146, such as a steel wire cleaning block, to fully cover the bottom working surface of the material cylinder 200, ensuring thorough cleaning without dead corners and complete removal of residue without any solidified residue.

[0063] Reference Figure 3 As shown, the support assembly 110 includes a support seat 111 supported on the opening 210 of the cylinder 200 and a hollow rib plate 112 connected to the support seat 111 and extending into the cylinder 200. The hollow rib plate 112 is connected to the motion conversion structure 130. The pull rod 120 passes through the support seat 111 and the hollow rib plate 112 in sequence and is connected to the motion conversion structure 130 in a transmission connection.

[0064] In a specific implementation, the support base 111 has an inclined surface that matches the opening 210 of the material cylinder 200, so as to be mounted on the opening 210 of the material cylinder 200. In order to connect the support base 111 and the connecting cylinder 161, a hollow rib plate 112 can be provided at one end of the support base 111 near the material cylinder 200 to connect the connecting cylinder 161 and the support base 111 into one unit.

[0065] Meanwhile, the hollow rib plate 112 can enhance the structural strength of the support base 111.

[0066] It should be noted that the hollow rib 112 can be an annular rib structure extending circumferentially along the support 111. Alternatively, the hollow rib 112 can be an arc-shaped structure extending circumferentially along the support 111, in which case at least two hollow ribs 112 can be provided circumferentially.

[0067] Reference Figure 3 As shown, the support assembly 110 is provided with at least one lifting component 113 to facilitate the hoisting of the entire residue cleaning device 100 into the material cylinder 200.
