Description

Technical Field

[0001] This invention belongs to the field of crane technology, and particularly relates to a crane climbing device. Background Technology

[0002] The climbing device of a crane is a core component that enables large equipment such as tower cranes to adjust their working position along the height of the tower crane. It primarily achieves lifting and lowering movements through the relative motion between the climbing device itself and the tower crane. The auxiliary wheels, as key components in contact between the climbing device and the tower crane, provide guidance and support by rolling along the tower crane's surface, directly affecting the stability and safety of the climbing process. In practical engineering applications, the climbing device must adapt to complex outdoor environments, enduring long-term heavy loads, wind forces, and changes in the surface condition of the tower crane. Its operational reliability is crucial to the overall operational efficiency and safety of the machine.

[0003] However, in the existing technology, the climbing device can only enable the crane to move upward. As a steel structure that is exposed to the outside world for a long time, the surface of the tower crane is prone to splashing dirt due to welding process residue, bulging due to rust, and dirt due to loose connecting parts. These attached dirt will form instantaneous impacts during the rolling of the auxiliary wheel, causing the auxiliary wheel to be lifted, amplifying the synchronization error of the hydraulic cylinder and causing the whole machine to jerk. At the same time, it will aggravate the pulsating impact of the hydraulic system, accelerate the fatigue of structural components and the aging of seals.

[0004] On the other hand, the surface of the tower crane may be dented due to rainwater erosion or dirt. When the auxiliary wheel passes through the dent, it may be momentarily suspended, causing the guiding force to suddenly disappear. Under the action of lateral wind load and the sway of the suspended load, the climbing device may easily slip sideways or even get stuck. In severe cases, it may cause local buckling of the tower crane or the entire machine to overturn. Summary of the Invention

[0005] The purpose of this invention is to provide a climbing device for a crane, which solves the technical problems in the prior art where the surface of the steel structure of the tower crane body, which is exposed for a long time, is prone to welding spatter, rust bulges and other contamination, which leads to impact on the auxiliary wheels, causing cylinder errors and jerking of the whole machine; at the same time, the depressions formed on the surface of the tower crane body due to corrosion or contamination can cause the auxiliary wheels to be suspended in the air, which can easily lead to slippage, jamming or even overturning risks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A climbing device for a crane includes a climbing device body with auxiliary wheels mounted on it that roll along the tower crane body. It also includes a balancing mechanism for real-time correction of surface defects on the tower crane body, ensuring the auxiliary wheels always travel on a stable tower crane body. The device further includes a drive assembly disposed on the side of the climbing device body; a cleaning assembly that, driven by the drive assembly, reciprocates linearly in a direction perpendicular to the climbing device body and cleans adhering dirt from the auxiliary wheels along their movement path; and a repair assembly that stores repair material and sprays the repair material during the upward movement of the crane driven by the climbing device body, repairing dents on the auxiliary wheels along their movement path.

[0008] Preferably, the cleaning component includes: a connecting block on which two connecting pipes are fixedly mounted; a first rotating shaft is rotatably mounted on the connecting block, and a friction block is fixedly mounted on the first rotating shaft.

[0009] Preferably, the cleaning assembly further includes: a drive box fixedly mounted on the connecting block, with a row of teeth fixedly installed inside; a sector gear located inside the drive box and meshing with the teeth; and a sliding frame slidably connected to the drive box.

[0010] Preferably, the drive assembly includes: a mounting box fixedly connected to the sliding frame; a dual-axis motor fixedly installed inside the mounting box, one end of which is fixedly connected to the sector gear, and the other end of which is fixedly installed with a second bevel gear; and a first rotating tube rotatably mounted on the mounting box, on which a first bevel gear meshing with the second bevel gear is fixedly installed.

[0011] Preferably, the balancing mechanism further includes a swing assembly, which comprises: a worm gear rotatably connected to the connecting tube, on which a worm wheel fixedly connected to the first rotating shaft meshes; two first connecting columns fixedly installed at both ends of the worm gear; a connecting plate fixedly installed on the sliding frame, on which a second rotating tube rotatably connected to the first connecting columns is rotatably installed; a drive column fixedly installed on the second rotating tube; a pressure ring matching the drive column and connected to the connecting plate via a first spring; wherein, a spiral track groove is provided on the end face of the pressure ring, and the end of the drive column is embedded in the track groove; when the pressure ring moves axially, the track groove drives the second rotating tube to rotate via the drive column.

[0012] Preferably, the balancing mechanism further includes a storage component, which includes a storage box for storing repair materials, and a partition is fixedly installed inside the box.

[0013] Preferably, the balancing mechanism further includes a buffer assembly, which includes: a slide rod fixedly mounted on the mounting box and extending into the storage box; a movable plate slidably mounted inside the storage box and fixedly connected to the slide rod, and connected to the storage box via a second spring.

[0014] Preferably, the balancing mechanism further includes an output component, which includes: a screw rotatably mounted on the partition plate, on which a first conical wheel is fixedly mounted, and on which a threaded plate slidably connected to the storage box is threadedly connected; a second connecting post rotatably connected to the partition plate, extending through the first conical gear to the outside of the mounting box, and coaxially arranged with the first conical gear, on which a second conical wheel is fixedly mounted; wherein the second connecting post does not contact the mounting box; and a movable frame fixedly connected to the movable plate, on which a drive belt for synchronous transmission of the first and second conical wheels is provided.

[0015] Preferably, the repair assembly includes: a one-way nozzle fixedly mounted on the partition; an adsorption roller rotatably mounted on the one-way nozzle, with a roller brush rotatably connected to the one-way nozzle below it; and an ultraviolet curing lamp fixedly mounted below the roller brush.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] 1. The cleaning component in this invention, driven by the drive component, reciprocates linearly in a direction perpendicular to the body of the climbing device, and moves upward synchronously with the body of the climbing device. Through the dual action of friction and compression, it cleans the dirt attached to the movement path of the auxiliary wheel. During this process, the repair component continuously sprays repair material to fill the depressions on the path. This effectively ensures that the movement path of the auxiliary wheel is always free of dirt and depressions, fundamentally avoiding the jamming or impact of the auxiliary wheel caused by uneven path, and realizing the continuous and stable operation of the crane climbing process.

[0018] 2. When the cleaning component in this invention moves back and forth, it squeezes the pressure ring of the swing component through the connecting pipe, thereby driving the friction block to swing back and forth at opposite angles. This swinging motion allows the friction block to find the weak points of the attached dirt. Combined with the upward movement of the climbing device body, it can apply more precise force to dirt with different degrees of adhesion. For dirt with weak adhesion, it can be peeled off quickly. For dirt with strong adhesion, it can also accelerate its removal by repeatedly applying force to the weak points, which significantly improves the cleaning efficiency and targeting of various types of attached dirt.

[0019] 3. The buffer component in this invention deforms accordingly with the force of the friction block squeezing the attached dirt, causing the moving plate to move a different distance. Then, the output component adjusts the rotation speed of the screw, so that the repair component can dynamically control the amount of repair material sprayed out according to the difficulty of cleaning the dirt. For larger dents caused by dirt that is difficult to clean, the amount of sprayed out is increased accordingly; otherwise, it is reduced, thus realizing a precise and rational adjustment of the repair method for dents caused by attached dirt.

[0037] This invention is described in detail with reference to the accompanying drawings.

Furthermore, the accompanying drawings are merely examples and should not be construed as limiting the scope of protection of this invention.

[0039] Unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" in this invention should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; similarly, they can refer to mechanical connections, electrical connections, or direct connections, or indirect connections through an intermediate medium, or internal connections 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.

[0040] Example 1: As Figures 1 to 8 As shown, a crane climbing device includes a climbing device body 100, on which auxiliary wheels 101 are mounted to roll along the tower crane body; a balancing mechanism 200 is used to correct surface defects of the tower crane body in real time, so that the auxiliary wheels 101 always travel on a stable tower crane body; it includes a drive component 210, a cleaning component 220, and a repair component 260. The drive component 210 is disposed on the side of the climbing device body 100; the cleaning component 220, driven by the drive component 210, reciprocates linearly in a direction perpendicular to the climbing device body 100 and cleans the dirt attached to the auxiliary wheels 101 along the movement path of the tower crane body; the repair component 260 stores repair material inside and sprays the repair material during the process of the climbing device body 100 driving the crane upward to repair the dents on the auxiliary wheels 101 along the movement path of the tower crane body.

[0041] It should be noted that the climbing device body 100 is mounted on the tower crane body. The auxiliary wheel 101 on the climbing device body 100 is in contact with the tower crane body. During the operation of the hydraulic system of the climbing device body 100, which drives the crane upwards as a whole, the auxiliary wheel 101 moves on the tower crane body. During this movement, since the cleaning component 220 is located on the path of the auxiliary wheel 101 along the tower crane body, and the climbing device body 100 will cause the cleaning component 220 to move upwards one step ahead of the auxiliary wheel 101, the drive component 210 can be activated. The drive component 210 controls the operation of the cleaning component 220, causing the cleaning component 220 to reciprocate in a straight line perpendicular to the climbing device body 100. In this way, the cleaning component 220 will rub against the attached dirt on the path of the auxiliary wheel 101 through the reciprocating straight line motion, and squeeze the attached dirt on the path, so that small attached dirt is cleaned faster and large attached dirt can be removed faster. During the operation of the drive component 210, the repair component 26 will also be activated. Repair material is sprayed out and spread evenly along the movement path of the auxiliary wheel 101 along the tower crane body. This repair material not only protects the auxiliary wheel 101 along its movement path but also repairs any dents or depressions along this path. These dents can be caused by loose contaminants or are inherent to the auxiliary wheel. This ensures that there are no contaminated or dented areas on the auxiliary wheel 101's movement path, allowing for smooth and continuous operation. This effectively solves the problems of auxiliary wheel 101 being lifted up due to attached dirt, generating impact load, amplifying the synchronization error of the hydraulic cylinder, and causing the whole machine to jerk; dents causing auxiliary wheel 101 to be suspended in the air for a moment, losing the guiding force, and causing the climbing device to slip laterally or even get stuck under the action of lateral wind load and the sway of the suspended load. It avoids the problems of reduced climbing efficiency, increased pulsation impact of hydraulic system, accelerated fatigue of structural components, and shortened life of seals caused by impact and slippage, which in severe cases may even cause local buckling of the tower crane body or overturning of the whole machine.

[0042] like Figures 1 to 6 As shown, the cleaning component 220 includes a friction block 221, a connecting pipe 222, a first rotating shaft 223, a connecting block 224, a retaining tooth 225, a drive box 226, a sector gear 227, and a sliding frame 228.

[0043] Two connecting pipes 222 are fixedly installed on the connecting block 224; a first rotating shaft 223 is rotatably installed on the connecting block 224, and a friction block 221 is fixedly installed on the first rotating shaft 223; a drive box 226 is fixedly installed on the connecting block 224, and a row of locking teeth 225 is fixedly installed inside the drive box 226; a sector gear 227 is located inside the drive box 226, and the sector gear 227 is meshed with the locking teeth 225; a sliding frame 228 is slidably connected to the drive box 226.

[0044] like Figure 8 As shown, the drive assembly 210 includes a dual-axis motor 211, a mounting box 212, a first bevel gear 213, a first rotating tube 214, and a second bevel gear 215.

[0045] Mounting box 212 is fixedly connected to sliding frame 228; dual-axis motor 211 is fixedly installed inside mounting box 212, one end of dual-axis motor 211 is fixedly connected to sector gear 227, and the other end of dual-axis motor 211 is fixedly installed with second bevel gear 215; first rotating tube 214 is rotatably installed on mounting box 212, and first bevel gear 213 that meshes with second bevel gear 215 is fixedly installed on first rotating tube 214.

[0046] It should be noted that when the climbing device body 100 is started, the dual-axis motor 211 can be started simultaneously. The dual-axis motor 211 will drive the sector gear 227 to rotate. The rotation of the sector gear 227 will engage with the locking teeth 225 to cause the drive box 226 to reciprocate inside the sliding frame 228. The reciprocating movement of the drive box 226 will drive the connecting block 224 to reciprocate, thereby causing the friction block 221 connected to it to also reciprocate. Since the friction block 221 is in contact with the tower crane body and is located on the movement path of the auxiliary wheel 101 along the tower crane body, during the reciprocating movement of the friction block 221, the climbing device body 100 will also cause the friction block 221 to continuously move upward. When the friction block 221 encounters attached dirt during its upward movement, the friction block 221 will squeeze the attached dirt due to the upward movement of the climbing device body 100, using the squeezing force to make the attached dirt fall off. On the other hand, the friction... The reciprocating movement of block 221 can generate friction on the attached dirt. For some small dirt, the friction of the friction block 221 can smooth it out and remove it. For some large dirt, the friction of the friction block 221 can continue to rub until it is removed. However, in this process, as the contact point between the attached dirt and the tower crane body becomes smaller and smaller, the friction block 221 will generate greater and greater squeezing force on the attached dirt under the support of the upward movement of the climbing device body 100. In this way, the two work together to remove the attached dirt more quickly. In addition, during the reciprocating movement, the friction block 221 can also perform preliminary grinding on the auxiliary wheel 101 along the moving path of the tower crane body. This not only avoids the presence of some small burrs on the auxiliary wheel 101 along the moving path of the tower crane body, which would affect subsequent repairs, but also grinds the area where the attached dirt has just been removed, avoiding the presence of warped edges or other phenomena that would affect subsequent repairs.

[0047] like Figures 4 to 7 As shown, the balancing mechanism 200 also includes a swing assembly 230, which includes a connecting plate 231, a first connecting column 232, a worm gear 233, a worm 234, a first spring 235, a drive column 236, a pressure ring 237, and a second rotating tube 238.

[0048] The worm 234 is rotatably connected to the connecting tube 222, and a worm wheel 233, which is fixedly connected to the first rotating shaft 223, is meshed on the worm 234; two first connecting columns 232 are respectively fixedly installed at both ends of the worm 234; the connecting plate 231 is fixedly installed on the sliding frame 228, and a second rotating tube 238, which is rotatably connected to the first connecting columns 232, is rotatably installed on the connecting plate 231; the drive column 236 is fixedly installed on the second rotating tube 238; the pressure ring 237 is matched with the drive column 236, and the pressure ring 237 is connected to the connecting plate 231 through the first spring 235.

[0049] It should be noted that when the connecting block 224 drives the friction block 221 to move back and forth under the drive of the dual-axis motor 211, the two connecting pipes 222 will move synchronously with it. During the movement, one connecting pipe 222 gradually approaches the adjacent pressure ring 237, while the other gradually moves away from the adjacent pressure ring 237. The pressure ring 237 has a track groove on its surface. The track grooves on the two pressure rings 237 are opened in opposite directions. Specifically, the track groove is a spiral groove, and the end of the drive column 236 is embedded in the track groove.

[0050] When one connecting pipe 222 presses the pressure ring 237 to move, the pressure ring 237 moves and drives the drive column 236 to rotate in the forward direction. When the connecting pipe 222 moves and resets, it drives another connecting pipe 222 to move in the other direction and presses another pressure ring 237. When the pressure ring 237 moves and drives the drive column 236 to rotate in the reverse direction, as the connecting block 224 drives the connecting pipe 222 to complete a reciprocating movement, the drive column 236 will drive the worm gear 234 to rotate forward and reset once and then in the reverse direction once through the second rotating pipe 238 and the first connecting column 232. This will cause the first rotating shaft 223 to drive the friction block 221 to rotate forward and reset once and then in the reverse direction once. As the reciprocating motion continues, the friction block 221 will continuously rotate forward by a specified angle, reset, and then rotate in the reverse direction by a specified angle, where the specified angle can be thirty degrees.

[0051] Since the friction block 221 is constantly reciprocating and moving upward under the action of the climbing device body 100, when the friction block 221 deflects at an angle, it will continue to reciprocate and move upward to act on the attached dirt. As the angle of the friction block 221 changes, the point of action on the attached dirt will also change. Since the connection between the attached dirt and the tower crane body is not necessarily firm in all aspects, there may be some loose points. When the angle of the friction block 221 changes, if it can directly act on the loose connection points of the attached dirt, the attached dirt can be cleaned more quickly.

[0052] like Figure 9 and Figure 10 and Figure 11As shown, the balancing mechanism 200 also includes a storage component 250, which includes a storage box 251 and a partition 252.

[0053] Storage box 251 is used to store repair materials, and a partition 252 is fixedly installed inside storage box 251.

[0054] The balancing mechanism 200 also includes a buffer assembly 240, which includes a slide bar 241, a second spring 242, and a movable plate 243.

[0055] The slide bar 241 is fixedly installed on the mounting box 212 and extends into the storage box 251; the movable plate 243 is slidably installed inside the storage box 251 and is fixedly connected to the slide bar 241, and is connected to the storage box 251 through the second spring 242.

[0056] It should be noted that when the lifting device body 100 moves the friction block 221 upward to squeeze the attached dirt, the attached dirt is not necessarily removed directly. This will squeeze the friction block 221 closer to the storage box 251, thereby stretching the second spring 242. The stretching of the second spring 242 not only gives the friction block 221 a buffer squeezing time to avoid excessive squeezing and damage, but also provides an upward thrust for the friction block 221 to assist the friction block 221 in squeezing the attached dirt.

[0057] The working principle of this embodiment is as follows: When the climbing device body 100 starts and drives the crane upward, the dual-axis motor 211 of the drive assembly 210 is started simultaneously. One end of the motor drives the sector gear 227 to rotate. Through the meshing with the locking teeth 225 inside the drive box 226, the drive box 226 reciprocates on the sliding frame 228, thereby driving the friction block 221 of the cleaning assembly 220 to reciprocate linearly in a direction perpendicular to the climbing device body 100. At the same time, the friction block 221 moves upward with the climbing device body 100, cleaning the attached dirt on the path of the auxiliary wheel 101 through the dual action of squeezing and friction.

[0058] During this process, the connecting block 224 drives the connecting pipe 222 to move back and forth, squeezing the pressure ring 237 of the swing assembly 230. Through the drive column 236, the second rotating pipe 238 and other transmission structures, the worm 234 rotates in both directions. The worm wheel 233 and the first rotating shaft 223 drive the friction block 221 to swing in both directions, precisely acting on the weak points of dirt to improve cleaning efficiency.

[0059] At the same time, when the friction block 221 squeezes the dirt, it will push the slide bar 241, causing the moving plate 243 of the buffer assembly 240 to stretch the second spring 242, using the spring force to buffer the squeezing force and assist in cleaning; the drive assembly 210 is linked with the repair assembly 260 to spray repair material to fill the dent, ultimately ensuring that the auxiliary wheel 101 moves along a smooth path.

[0060] Example 2: As Figures 9 to 12 As shown, while all other parts are the same as in Example 1, the difference between this example and Example 1 is that:

[0061] The balancing mechanism 200 also includes an output component 270, which includes a second connecting post 271, a moving frame 272, a screw 273, a drive belt 274, a first conical wheel 275, a second conical wheel 276, and a threaded plate 277.

[0062] The screw 273 is rotatably mounted on the partition 252. A first conical wheel 275 is fixedly mounted on the screw 273, and a threaded plate 277 that is slidably connected to the storage box 251 is threaded onto it. The second connecting post 271 is rotatably connected to the partition 252. The second connecting post 271 passes through the first rotating tube 214 and the first conical gear 213 and extends to the outside of the mounting box 212. The second connecting post 271 is a rectangular post, and the inside of the first rotating tube 214 has a groove that matches the second connecting post 271, so that the second connecting post 271 and the first rotating tube 214 can slide up and down. Furthermore, when the first bevel gear 213 drives the first rotating tube 214 to rotate, it also drives the second connecting column 271 to rotate. The second connecting column 271 is fixedly mounted with a second conical wheel 276. The second connecting column 271 does not contact the mounting box 212. The moving frame 272 is fixedly connected to the moving plate 243. The moving frame 272 is provided with a drive belt 274 for synchronous transmission of the first conical wheel 275 and the second conical wheel 276. Specifically, the drive belt 274 is an elastic synchronous belt, which is sleeved on the teeth of the first conical wheel 275 and the second conical wheel 276. The moving frame 272 is a U-shaped frame.

[0063] Repair assembly 260 includes an adsorption roller 261, a one-way nozzle 262, an ultraviolet curing lamp 263, and a roller brush 264.

[0064] A one-way nozzle 262 is fixedly mounted on a partition plate 252; an adsorption roller 261 is rotatably mounted on the one-way nozzle 262, and a roller brush 264 is provided below the adsorption roller 261 and rotatably connected to the one-way nozzle 262; an ultraviolet curing lamp 263 is fixedly mounted below the roller brush 264.

[0065] It should be noted that, since there may be some attached dirt on the auxiliary wheel 101 along the movement path of the tower crane body, after this dirt is cleaned, some depressions will appear on the auxiliary wheel 101 along the movement path of the tower crane body. These depressions will affect the movement of the auxiliary wheel 101. Therefore, when the dual-shaft motor 211 starts working, it will also drive the first rotating tube 214 and the first bevel gear 213 to rotate through the second bevel gear 215. The first bevel gear 213 drives the second connecting column 271 to rotate. The second connecting column 271 drives the screw 273 to rotate through the drive belt 274, the first cone wheel 275 and the second cone wheel 276. The rotation of the screw 273 causes the threaded plate 277 to move upward. The upward movement of the threaded plate 277 will squeeze the repair material inside the storage box 251, causing the repair material to be sprayed out from the one-way nozzle 262 and attached to the tower crane body. The repair material can be a UV-curable material, such as UV-curable resin.

[0066] Furthermore, due to the action of the climbing device body 100, the adsorption roller 261 will move up to fit the tower crane body. The adsorption roller 261 will adsorb the impurities on the tower crane body. Then, the repair material will be sprayed out. The sprayed repair material will be smoothed by the roller brush 264, so that the auxiliary wheel 101 moves smoothly along the tower crane body. Finally, it will be cured by the ultraviolet curing lamp 263, which will facilitate the subsequent movement of the auxiliary wheel 101.

[0067] Smaller deposits have a smaller surface area compared to larger deposits, making them easier to remove by the friction block 221. Consequently, the distance the friction block 221 causes the moving plate 243 to stretch the second spring 242 is correspondingly shorter. Conversely, larger deposits have a larger surface area and are more difficult to remove by the friction block 221. Therefore, the distance the moving plate 243 moves the moving frame 272 downwards depends on the difficulty of cleaning. When the moving frame 272 moves downwards, the tension of the drive belt 274 increases, causing a change in the meshing radius of the first conical wheel 275 and the second conical wheel 276, thereby increasing the rotational speed of the screw 273. Thus, the further the moving frame 272 moves downwards, the faster the screw 273 rotates. The faster the threaded plate 277 moves upward, the more repair material the one-way nozzle 262 sprays in the same amount of time. This provides an appropriate amount of repair material for dents caused by the removal of attached dirt of different sizes. When the dual-shaft motor 211 is working normally and the friction block 221 does not encounter any attached dirt, the threaded plate 277 has a basic feed, causing the one-way nozzle 262 to spray a small amount of repair material. This repair material can repair some small dents on the auxiliary wheel 101 along the movement path of the tower crane body, making the auxiliary wheel 101 move more stably. On the other hand, it can protect the tower crane body and prevent damage to the internal structure under the outer protective layer of the tower crane body due to external environmental factors such as rainwater erosion during long-term use.

[0068] The working principle of this embodiment is as follows: Based on embodiment 1, the other end of the dual-axis motor 211 meshes with the first bevel gear 213 through the second bevel gear 215, which drives the first rotating tube 214 to rotate. Then, through the second connecting column 271, the drive belt 274 and the bevel gear transmission structure, the screw 273 of the output component 270 is driven to rotate, so that the threaded plate 277 moves upward to squeeze the repair material in the storage box 251.

[0069] When the friction block 221 cleans the dirt, the moving plate 243 of the buffer assembly 240 moves with the squeezing force. The transmission efficiency of the drive belt 274 is adjusted by the moving frame 272, so that the rotation speed of the screw 273 changes with the difficulty of cleaning the dirt. The greater the difficulty of cleaning, the faster the threaded plate 277 moves upward and the more repair material is sprayed by the one-way nozzle 262 to match the size of the dent.

[0070] Meanwhile, the adsorption roller 261 first adsorbs impurities on the tower crane body, the roller brush 264 smooths out the sprayed repair material, and the ultraviolet curing lamp 263 cures it; under normal conditions, the repair component 260 sprays a small amount of material to fill small dents and protect the tower crane body, ensuring that the auxiliary wheel 101 always moves on a stable path.
