Technical Field
[0001] This application relates to the field of tunneling machine technology, and in particular to a tunneling machine main bearing roller transfer device and its usage method. Background Technology
[0002] Remanufacturing of tunneling machines is a current global trend in the tunnel boring machine (TBM) market. The main bearing, as the "heart" of the TBM, typically has a structure with three rows of cylindrical rollers. As a key component of the main bearing, the rollers play a supporting role and reduce friction. They bear the entire heavy load during operation and are also the main wear-prone components of the TBM main bearing.
[0003] During the maintenance and remanufacturing of tunneling machines, the main bearings need to be disassembled, inspected, and tested. However, the main bearings of tunneling machines are generally large in size (φ3~φ8.6m), and these extra-large diameter bearings are not easily adapted to automated equipment like the smaller diameter bearings commonly used in the market. Furthermore, the rollers of tunneling machine main bearings are generally large, heavy, and numerous. Therefore, the disassembly and inspection of rollers constitutes a major portion of the labor time during the disassembly and inspection of tunneling machine main bearings in remanufacturing.
[0004] However, in the remanufacturing of tunneling machine main bearings, the disassembly and inspection of rollers are mainly carried out by manual handling, which is inefficient and labor-intensive for the workers. Summary of the Invention

The inclined plate is provided with a fixing member, which passes through the adjustment groove and is connected to the limiting plate to fix the limiting plate.
[0016] In some embodiments, the cleaning assembly includes an ultrasonic cleaner, and a receiving cavity is provided in the vehicle body. The ultrasonic cleaner is disposed in the receiving cavity to drive the cleaning fluid in the vehicle body to vibrate at high frequency.
[0017] In some embodiments, the unloading assembly includes a conveyor belt, a demagnetizer, and an air cooler. The conveyor belt is disposed on the outer side wall of the vehicle body; the air cooler is disposed on the vehicle body and blows air toward the conveyor belt to dry the bearing rollers; the demagnetizer is disposed on the vehicle body and located above the unloading end of the conveyor belt to demagnetize the air-dried bearing rollers.
[0018] In some embodiments, the unloading assembly further includes an unloading ramp disposed on the vehicle body, the unloading ramp being smoothly connected to the unloading end of the conveyor belt, so that the bearing roller slides onto the unloading ramp and slides out of the vehicle body.

[0026] This application provides a main bearing roller transfer device and its usage method for a tunneling machine. The device utilizes a cantilever lifting component, a first suction component, and a second suction component mounted on the vehicle body. The cantilever lifting component moves the positions of the first and second suction components, allowing the first suction component to pick up the disassembled bearing rollers. The cantilever lifting component then places the bearing rollers into the vehicle body, reducing the labor intensity of manual handling. After multiple bearing rollers are placed into the vehicle body, a cleaning component cleans them. This cleaning process can be performed simultaneously with the vehicle's movement, improving the efficiency of bearing roller transfer. After cleaning, the second suction component picks up the bearing rollers and places them onto a feeding component. The feeding component dries the bearing rollers and removes them from the vehicle body, completing the entire transfer process. The first and second suction components are used for both loading and unloading, ensuring that the second suction component remains clean during unloading and preventing secondary contamination of the bearing rollers.

[0043] Remanufacturing of tunneling machines is a current global trend in the tunnel boring machine (TBM) market. The main bearing, as the "heart" of the TBM, typically has a structure with three rows of cylindrical rollers. As a key component of the main bearing, the rollers play a supporting role and reduce friction. They bear the entire heavy load during operation and are also the main wear-prone components of the TBM main bearing.
[0044] During the maintenance and remanufacturing of tunneling machines, the main bearings need to be disassembled, inspected, and tested. However, the main bearings of tunneling machines are generally large in size (φ3~φ8.6m), and these extra-large diameter bearings are not easily adapted to automated equipment like the smaller diameter bearings commonly used in the market. Furthermore, the rollers of tunneling machine main bearings are generally large, heavy, and numerous. Therefore, the disassembly and inspection of rollers constitutes a major portion of the labor time during the disassembly and inspection of tunneling machine main bearings in remanufacturing.
[0045] However, in the remanufacturing of tunneling machine main bearings, the disassembly and inspection of rollers are mainly carried out by manual handling, which is inefficient and labor-intensive for the workers.
[0046] To address the aforementioned problems, this application provides a main bearing roller transfer device and its usage method for tunneling machines. The main bearing roller transfer device for tunneling machines utilizes a cantilever lifting component, a first suction component, and a second suction component mounted on the vehicle body. The cantilever lifting component moves the positions of the first and second suction components, allowing the first suction component to pick up the disassembled bearing rollers. The cantilever lifting component then places the bearing rollers into the vehicle body, reducing the labor intensity of manual handling by operators. Furthermore, after multiple bearing rollers are placed into the vehicle body, a cleaning component cleans the bearing rollers.

[0047] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.
[0048] On the one hand, this application provides a roller transfer device for the main bearing of a tunneling machine, referring to... Figures 1 to 5 The tunneling machine main bearing roller transfer equipment includes a vehicle body 100, a gripping component 200, a cleaning component 300, and a feeding component 400.
[0049] The car body 100 is used to mount and transfer bearing rollers;
[0050] The gripping assembly 200 includes a cantilever lifting component 210, a first adsorption component 220, and a second adsorption component 230. The cantilever lifting component 210 is rotatably mounted on the vehicle body 100. The first adsorption component 220 and the second adsorption component 230 are both mounted on the cantilever lifting component 210. The cantilever lifting component 210 drives the first adsorption component 220 and the second adsorption component 230 to rise and fall. The first adsorption component 220 is used to pick up bearing rollers and place them into the vehicle body 100. The second adsorption component 230 is used to pick up bearing rollers inside the vehicle body 100 and place them into the unloading assembly 400.
[0051] The cleaning assembly 300 is disposed inside the vehicle body 100 for cleaning the bearing rollers inside the vehicle body 100;
[0052] The unloading assembly 400 is mounted on the vehicle body 100 to dry the bearing rollers located on the unloading assembly 400 and to remove the bearing rollers from the vehicle body 100.
[0053] in, Figure 1 and Figure 3 Only the first adsorption element 220 is shown in the diagram.
[0054] By adopting the above technical solution, the cantilever lifting component 210 is driven to move the position of the first adsorption component 220, so that the first adsorption component 220 can be used to pick up the disassembled bearing rollers. The bearing rollers are then placed into the vehicle body 100 via the cantilever lifting component 210, reducing the labor intensity of manual handling by operators. Furthermore, after multiple bearing rollers are placed into the vehicle body 100, the bearing rollers are cleaned by the cleaning component 300. The cleaning process can be carried out simultaneously with the movement and transportation of the vehicle body 100, thereby improving the reuse efficiency of the bearing rollers. After cleaning, the second adsorption component 230 is used to pick up the bearing rollers onto the unloading component 400. The unloading component 400 dries the bearing rollers and removes them from the vehicle body 100, thus realizing the entire transfer process of the bearing rollers. During the loading and unloading processes, the first adsorption component 220 and the second adsorption component 230 are used for picking up the rollers, ensuring that the second adsorption component 230 remains clean during unloading, avoiding secondary contamination of the bearing rollers.
[0055] Among them, reference Figure 1 and Figure 2 The vehicle body 100 includes a housing 110, a handle 120, and multiple wheels 130. The housing 110 has a top-opening structure, and its interior forms a cavity for housing bearing rollers. The handle 120 is mounted on the outer wall of the housing 110 to facilitate moving the housing 110 by pushing it. The internal hardness of the housing 110 is lower than that of the bearing rollers to prevent damage from impacts during rolling within the housing 110.
[0056] Multiple wheels 130 are installed at the bottom of the housing 110. In this embodiment, four wheels 130 are provided, and at least two wheels 130 are omnidirectional wheels with a self-locking structure, so that the operator can park the vehicle body 100 in any position and reduce unnecessary sliding of the vehicle body 100.
[0057] In some embodiments, the cantilever lifting component 210 includes a lifting arm 211, a track 212, a trolley 213, and a hoist 214. The lifting arm 211 is rotatably mounted on the vehicle body 100, the track 212 is mounted horizontally on the lifting arm 211, and the trolley 213 is slidably mounted on the track 212 so that the trolley 213 slides horizontally. The hoist 214 is mounted on the trolley 213, and the first suction member 220 and the second suction member 230 are both mounted on the hoist 214 so that the hoist 214 drives the first suction member 220 and the second suction member 230 to rise and fall.
[0058] The lifting arm 211 includes a vertical rod and a horizontal beam. The vertical rod is rotatably mounted on the end of the vehicle body 100 near the handle 120, and the axis of rotation of the vertical rod is vertical. One end of the horizontal beam is fixed to the top of the vertical rod, and the horizontal beam is perpendicular to the vertical rod. The length of the horizontal beam is greater than the length of the vehicle body 100 to facilitate gripping the bearing rollers. The height of the vertical rod is greater than the height of the vehicle body 100 to facilitate hoisting the bearing rollers into the vehicle body 100.
[0059] A track 212 is installed at the bottom of the crossbeam and is arranged along the length of the crossbeam. A trolley 213 is slidably connected to the track 212 to adjust the horizontal position of the first suction member 220 and the second suction member 230. A limiting block may also be provided at the end of the track 212 to prevent the trolley 213 from sliding off the track 212. The trolley 213 can be a manual structure, pushed by hand; it can also be driven by an electric or hydraulic structure, which will not be elaborated further here.
[0060] The hoist 214 is mounted on the trolley 213. The hoist 214 is a commonly used mechanism such as an electric hoist or lifting platform. The hoist 214 can be installed normally, fixing it to the trolley 213 so that the chain or lifting structure is connected to the first suction member 220 and the second suction member 230. Alternatively, the hoist 214 can be installed upside down, with the chain or lifting structure mounted on the trolley 213 and the first and second suction members 220 and 230 mounted on the hoist 214 body.
[0061] Furthermore, a gripping part 240 is fixed on the hoist 214, and the first suction member 220 and the second suction member 230 are both connected to the gripping part 240. This allows the operator to grip the gripping part 240 and adjust the position of the first suction member 220 and the second suction member 230, facilitating precise operation of the first suction member 220 and the second suction member 230 to pick up the bearing rollers.
[0062] Furthermore, to facilitate the suction of the bearing rollers, both the first suction member 220 and the second suction member 230 are hinged to the bottom of the gripping portion 240. The first suction member 220 and the second suction member 230 are hinged side by side to the bottom of the gripping portion 240, and both the first suction member 220 and the second suction member 230 have two fixed positions, with an angle between the two fixed positions greater than or equal to 90°.
[0063] By adopting the above technical solution, when the first adsorption member 220 needs to be used, it is rotated to a vertical position, directly below the bottom of the holding part 240, so that the first adsorption member 220 is facing the removed bearing rollers; the second adsorption member 230 is rotated and fixed above the horizontal position, so that the first adsorption member 220 can be used alone, avoiding contamination of the second adsorption member 230 with oil. When the second adsorption member 230 needs to be used, it is rotated to a vertical position, directly below the bottom of the holding part 240, and the first adsorption member 220 is rotated and fixed above the horizontal position. This allows a clean adsorption member to pick up the cleaned bearing rollers, preventing recontamination of the bearing rollers.
[0064] In some embodiments, refer to Figure 1 and Figure 4 The first adsorption element 220 is a magnetic chuck, and the second adsorption element 230 is a vacuum chuck.
[0065] During the remanufacturing of the main bearing, the surface of the bearing rollers is generally covered with lubricating oil. Using magnetic adsorption components for suction is faster and safer. After cleaning, the bearing rollers are clean. Considering that the surface of the bearing rollers must not have oil stains, a vacuum adsorption component is used to adsorb the rolling surface of the bearing rollers, and then they are gently placed in the pocket to prevent the bearing rollers from falling and damaging the raceway 114 due to their own weight.
[0066] In some embodiments, one side of the vehicle body 100 is provided with an inclined plate 111, which is used to allow bearing rollers to roll into the vehicle body 100. The inclined plate 111 is provided with a raceway 114 for the bearing rollers to roll down.
[0067] The inclined plate 111 is the side plate of the housing 110 away from the handle 120. The distance from the bottom of the inclined plate 111 to the handle 120 is less than the distance from the top of the inclined plate 111 to the handle 120. When hoisting the bearing rollers, the bearing rollers are placed on the raceway 114 on the inclined plate 111 so that the bearing rollers roll from the raceway 114 to the bottom of the housing 110, thereby reducing the impact caused to the bearing rollers during hoisting.
[0068] In some embodiments, a plurality of limiting plates 112 are provided on the inclined plate 111. The limiting plates 112 are arranged horizontally on the side of the inclined plate 111 facing the vehicle body 100, and a raceway 114 is formed between adjacent limiting plates 112. The bearing rollers roll along the raceway 114 into the vehicle body 100 to reduce the impact of the bearing rollers.
[0069] Furthermore, the inclined plate 111 is provided with an adjustment groove 113 arranged in the horizontal direction. The limiting plate 112 is slidably inserted into the adjustment groove 113 to adjust the distance between two adjacent limiting plates 112, thereby adjusting the width of the raceway 114. The inclined plate 111 is provided with a fixing member 115, which passes through the adjustment groove 113 and connects to the limiting plate 112 to fix the limiting plate 112.
[0070] The adjusting groove 113 is located at the top of the inclined plate 111 to prevent the cleaning fluid inside the housing 110 from flowing out of the adjusting groove 113. The limiting plate 112 can be a straight plate or an L-shaped plate. When the limiting plate 112 is an L-shaped plate, one side of the limiting plate 112 abuts against the inclined plate 111, thereby improving the stability of the limiting plate 112 and reducing its wobbling. By adjusting the position between the limiting plates 12, the width of the raceway 114 can be adjusted to accommodate bearing rollers of different sizes, improving the adaptability of the equipment.
[0071] The fastener 115 is a bolt, which passes through the adjustment groove 113 and is threaded to the limiting plate 112. The bolt head abuts against the outer wall of the inclined plate 111 to fix the limiting plate 112.
[0072] In some embodiments, the cleaning assembly 300 includes an ultrasonic cleaner, and a receiving cavity is provided inside the vehicle body 100. The ultrasonic cleaner is disposed in the receiving cavity to drive the cleaning fluid inside the vehicle body 100 to vibrate at high frequency.
[0073] The receiving cavity is a frame structure installed inside the housing 110 for mounting the ultrasonic cleaner. During use, cleaning fluid is first placed into the housing 110. Once the bearing rollers have completely rolled into the housing 110, the ultrasonic cleaner is activated, emitting a high-frequency oscillation signal. This signal is converted into high-frequency mechanical oscillations by a transducer and propagates into the cleaning fluid, thereby removing oil and other contaminants from the bearing rollers. The cleaning fluid can be water with detergent, or other formulated cleaning agents.
[0074] Furthermore, a drain pipe 140 is provided at the bottom of the housing 110, and a valve is installed on the drain pipe 140 for opening and closing the drain pipe 140. After cleaning is completed, the vehicle body 100 is moved to the wastewater discharge area, and the valve is opened to drain the cleaning fluid in the housing 110.
[0075] In some embodiments, the unloading assembly 400 includes a conveyor belt 410, a demagnetizer 420, and an air cooler 430. The conveyor belt 410 is disposed on the outer side wall of the vehicle body 100; the air cooler 430 is disposed on the vehicle body 100 and blows air toward the conveyor belt 410 to dry the bearing rollers; the demagnetizer 420 is disposed on the vehicle body 100 and located above the unloading end of the conveyor belt 410 to demagnetize the dried bearing rollers.
[0076] After the bearing rollers are cleaned and the cleaning fluid is drained, the second adsorption element 230 is used to pick up the bearing rollers in the box 110 and place them on the conveyor belt 410. The conveyor belt 410 is set horizontally so that the bearing rollers are dried by the air cooler 430, demagnetized by the demagnetizer 420, and then removed from the vehicle body 100.
[0077] Since the bearing must not be magnetized during operation, the bearing rollers need to be demagnetized. The cleaning agents used for the bearing rollers are generally volatile, and using an air cooler 430 can dry the surface of the bearing rollers more quickly.
[0078] Furthermore, the unloading assembly 400 also includes an unloading ramp 440, which is disposed on the vehicle body 100 and is smoothly connected to the unloading end of the conveyor belt so that the bearing rollers slide onto the unloading ramp 440 and slide out of the vehicle body 100.
[0079] The side of the feed sloping plate 440 is equipped with a baffle to prevent the bearing rollers from rolling off the edge of the feed sloping plate 440. The bottom of the feed sloping plate 440 can be used with a receiving container such as a pallet or wooden box. The inside of the receiving container should be made of a relatively soft material to avoid damage to the rollers.
[0080] On the other hand, this application provides a method for using a tunneling machine main bearing roller transfer device. The method using the aforementioned tunneling machine main bearing roller transfer device includes:
[0081] Move the vehicle body 100 to the main bearing to be disassembled.
[0082] First, place a suitable cleaning solution inside the housing 110, then push the vehicle body 100 to the main bearing to be disassembled.
[0083] Rotate the cantilever lifting component 210 to move the first adsorption component 220 above the bearing roller to be removed on the main bearing, and lower the first adsorption component 220 to pick up the bearing roller.
[0084] Adjust the first adsorption member 220 to the vertical direction, and rotate the second adsorption member 230 above the first adsorption member 220; then rotate the cantilever lifting member 210 and move the trolley 213 so that the first adsorption member 220 is located above the main bearing. Lower the first adsorption member 220 through the hoist 214 and use the first adsorption member 220 to adsorb a bearing roller. During this process, the operator holds the grip part 240 to adjust the position of the first adsorption member 220 so that the first adsorption member 220 can accurately pick up the bearing roller.
[0085] Adjust the cantilever lifting component 210 to move the first adsorption component 220 and the bearing roller into the vehicle body 100.
[0086] The lifting machine 214 is adjusted to raise the first adsorption component 220, and the hoisting arm 211 is rotated to move the first adsorption component 220 to the inclined plate 111. Then, the first adsorption component 220 is lowered so that the bearing rollers contact the inclined plate 111. The first adsorption component 220 is then controlled to release the bearing rollers, so that the bearing rollers roll into the cleaning fluid inside the housing 110. The above gripping operation is repeated to place multiple bearing rollers into the housing 110. The number of bearing rollers placed in the housing 110 varies according to the volume of the housing 110.
[0087] After moving multiple bearing rollers into the vehicle body 100, the cleaning assembly 300 is activated to clean the bearing rollers, and then the vehicle body 100 is moved to the storage location of the bearing rollers.
[0088] During the cleaning process of vehicle body 100, vehicle body 100 can be moved synchronously to save processing time. After cleaning, vehicle body 100 is moved to the placement area of bearing rollers, which is also the wastewater discharge point. The cleaning fluid tray in tank 110 is drained first to expose the bearing rollers before hoisting.
[0089] Rotate the cantilever lifting component 210 above the vehicle body 100, and use the second suction component 230 to pick up the cleaned bearing rollers.
[0090] Adjust the second adsorption element 230 to the vertical direction, rotate the first adsorption element 220 to above the horizontal direction, then rotate the lifting arm 211, adjust the position of the trolley 213, and use the hoist 214 to lower the second adsorption element 230 into the box 110 to pick up the cleaned bearing rollers.
[0091] Adjust the cantilever lifting component 210 to place the bearing rollers onto the unloading assembly 400. The unloading assembly 400 dries the bearing rollers and then sends them out of the vehicle body 100.
[0092] The bearing rollers are placed on conveyor belt 410, dried by air cooler 430 and demagnetized by demagnetizer, and then placed into corresponding receiving containers via discharge ramp 440. Buffer material, such as sponge, is placed inside the receiving containers to prevent damage to the cleaned bearing rollers. The above steps are repeated until all rollers of the main bearing are disassembled and cleaned.
[0093] Perform PT flaw detection on the cleaned bearing rollers near or next to the vehicle body 100.
[0094] The PT test is used to determine the condition of the roller. If the PT test fails, the roller is deemed defective and should be scrapped. If the PT test passes, the roller is deemed to be in good condition and can continue to be used. The above-mentioned transfer equipment is then used to lift the qualified bearing rollers for cleaning, and the colorant and developer on the bearing rollers are thoroughly cleaned.
[0095] Assemble the bearing rollers: Place the auxiliary push cage circumferentially onto the auxiliary push raceway 114; hold the gripping part 240 so that the second suction member 230 adsorbs the rolling surface of the auxiliary push roller, and place the roller into the pocket of the auxiliary push cage. Compared with manual handling, this process avoids the risk of slipping, prevents damage to the raceway 114 caused by manually placing the roller into the pocket, and reduces labor intensity.
[0096] Lift the inner ring; lift the radial cage to the end face of the bearing inner ring, grasp the grip 240, so that the second adsorption member 230 adsorbs the radial roller rolling surface, place the radial roller in the pocket of the radial cage, and assemble the radial cage and radial roller together into the radial raceway 114.
[0097] The main pusher retainer is hoisted and positioned circumferentially on the main pusher raceway 114. The gripping part 240 is held so that the second suction member 230 adsorbs the rolling surface of the main pusher roller, placing the main pusher roller into the pocket of the main pusher retainer. Compared to manual handling, this process avoids the risk of slipping and damage to the raceway 114 caused by manually placing the roller into the pocket, and also reduces labor intensity. The first outer ring is then hoisted, completing the assembly.
[0098] This application provides a method for using a main bearing roller transfer device for a tunneling machine. The method involves moving the positions of the first suction member 220 and the second suction member 230 via a cantilever lifting member 210. The first suction member 220 picks up the disassembled bearing rollers, and the cantilever lifting member 210 places the bearing rollers into the vehicle body 100, reducing the labor intensity of manual handling by operators. Furthermore, after multiple bearing rollers are placed into the vehicle body 100, the bearing rollers are cleaned by a cleaning assembly 300. The cleaning process can be carried out simultaneously with the movement and transportation of the vehicle body 100, thereby improving the reuse efficiency of the bearing rollers. After cleaning, the bearing rollers are picked up by the second adsorption component 230 and placed onto the unloading assembly 400. The unloading assembly 400 dries the bearing rollers and removes them from the vehicle body 100, thus completing the entire transfer process of the bearing rollers. During the loading and unloading processes, the first adsorption component 220 and the second adsorption component 230 are used for picking up the rollers, thereby keeping the second adsorption component 230 clean at all times and avoiding secondary contamination of the bearing rollers.
