Description

Technical Field

[0001] This invention relates to the field of track technology, and in particular to a rotating wheel device, a track device, and a working machine. Background Technology

[0002] Tracked systems are widely used due to their advantages such as strong adaptability, high load-bearing capacity, good stability, high friction, flexible operation, and convenient maintenance. For example, in terrains such as mud, sand, or snow, where the coefficient of friction is low, wheeled systems cannot provide sufficient driving force, making it difficult for machinery to move on these terrains. Tracked systems, on the other hand, can improve the stability and driving force of the equipment by utilizing the large contact area of ​​the tracks.

[0003] Tracked systems typically include a suspension, a drive wheel assembly, and tracks. The suspension is connected to the frame of the work machinery. The drive wheel assembly is mounted on the suspension and is located inside the tracks, supporting them so that the tracks can move along the drive wheel assembly, thus enabling the tracked system to move. The drive wheel assembly includes guide wheels and track rollers.

[0004] In related technologies, shock-absorbing devices are installed between the rotating wheel assembly and the suspension to reduce the impact between them. As mentioned above, rotating wheel assemblies typically have at least two types of rotating wheels, such as guide wheels and support rollers. When the shock-absorbing device of one of the rotating wheels fails, it may not affect the walking function of the track system, making it difficult for the operator to detect in time. However, the damage to one or more shock-absorbing devices will undoubtedly increase the load on other shock-absorbing devices or rotating wheels, easily accelerating their damage. Summary of the Invention

[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0048] In related technologies, shock-absorbing devices are installed between the rotating wheel assembly and the suspension to reduce the impact between them. As mentioned above, rotating wheel assemblies typically have at least two types of rotating wheels, such as guide wheels and support rollers. When the shock-absorbing device of one of the rotating wheels fails, it may not affect the walking function of the track system, making it difficult for the operator to detect in time. However, this will undoubtedly increase the load on other shock-absorbing devices or rotating wheels, easily accelerating their damage.

[0049] To address the technical problem in the prior art where operators cannot promptly detect the failure of the shock absorption device on the rotating wheel, and to achieve the effect of enabling operators to be aware of the damage in a timely manner when the shock absorption device fails, this invention provides a rotating wheel device, a track device, and a working machine.

[0050] The following is combined with Figures 1 to 16 The rotating wheel device commonly used in embodiments of the present invention is described.

[0051] Specifically, the rotating wheel device includes a mounting base 1, a rotating wheel 9, a shock absorption device 2, a detection device 13, and a control component 14.

[0052] The shock absorber 2 is installed on the mounting base 1, meaning the shock absorber 2 is connected to the mounting base 1. The mounting base 1 can be connected to the frame of the working machinery, or the mounting base 1 can also be the frame of the working machinery.

[0053] The rotating wheel 9 is rotatably mounted on the shock-absorbing device 2. It should be noted that the track roller 902 and idler wheel of a typical track device are subject to impact and therefore require the shock-absorbing device 2, while other components such as the drive wheel 8 and tensioner 6 do not require the shock-absorbing device 2. Therefore, for a track device, the rotating wheel 9 can be either the track roller 902 or the idler wheel. Optionally, the track roller 902 or the idler wheel includes a support shaft and a wheel body rotatably mounted on the support shaft, wherein the support shaft is connected to the shock-absorbing device 2.

[0054] The detection device 13 is used to detect the floating amount of the rotating wheel 9 or the floating amount of the shock absorber 2 during the process of the rotating wheel 9 compressing the shock absorber 2.

[0055] The control component 14 is connected to the detection device 13. The control component 14 sends an alarm message based on the floating amount of the rotating wheel 9 or the floating amount of the shock absorber 2. The control component 14 activates the alarm message when it determines that the floating amount of the rotating wheel 9 exceeds a first floating amount threshold, or the floating amount of the shock absorber 2 exceeds a second floating amount threshold. Depending on actual needs, the first and second floating amount thresholds may be equal or unequal. Optionally, under conditions of damage or malfunction of the shock absorber 2, when the rotating wheel 9 is impacted and compresses the shock absorber 2, the shock absorber 2 cannot provide effective buffering for the rotating wheel 9, resulting in an increase in the floating amount of the rotating wheel 9 or the shock absorber 2. Therefore, the control component 14 sends an alarm message when it determines that the floating amount of the rotating wheel 9 or the shock absorber 2 is greater than a preset floating amount threshold. Optionally, the control component 14 can be the overall vehicle control system of the operating machinery, or it can be a controller that separately controls the rotating wheel device.

[0056] In summary, the rotating wheel device provided in this embodiment of the invention, by setting a shock-absorbing device 2 between the mounting base 1 and the rotating wheel 9, allows the rotating wheel 9 to compress the shock-absorbing device 2 when impacted by the ground or a protrusion, causing the rotating wheel 9 to move upward, thereby buffering the rotating wheel 9 and reducing the vibration transmitted from the rotating wheel 9 to the mounting base 1, and reducing the impact on the rotating wheel 9. The detection device 13 can detect the floating amount of the rotating wheel 9 or the shock-absorbing device 2 during the compression process of the rotating wheel 9. The control component 14, connected to the detection device 13, triggers an alarm based on the floating amount of the rotating wheel 9 or the shock-absorbing device 2, so that the operator is aware that the shock-absorbing device 2 is damaged and needs timely repair or replacement.

[0057] With this configuration, the rotating wheel device provided in this embodiment of the invention can obtain the floating amount of the rotating wheel 9 or the floating amount of the shock absorber 2 through the detection device 13, and the control component 14 can send alarm information based on the floating amount so that the operator can know in time that the shock absorber 2 has been damaged.

[0058] In some embodiments provided by the present invention, the control component 14 sends alarm information including:

[0059] The control component 14 is connected to the alarm 15 and sends alarm information to the alarm 15 based on a floating amount, so as to control the alarm 15 to sound an alarm upon receiving the alarm information. The alarm 15 can be a warning light, a speaker, or an audible and visual alarm 15.

[0060] In this embodiment, the control component 14 controls the alarm 15 to sound an alarm, which can better alert the operator to information about damage to the shock absorber 2.

[0061] Furthermore, the number of alarms 15 is the same as the number of shock absorbers 2 and corresponds one-to-one. The number of detection devices 13 is the same as the number of shock absorbers 2 and corresponds one-to-one. The control component 14 controls the corresponding alarm 15 to sound based on the floating amount detected by the corresponding detection device 13, so that the operator can clearly and quickly find the damaged shock absorber 2, thereby reducing the time required to troubleshoot the shock absorber 2.

[0062] Of course, the control component 14 is not limited to being connected to the alarm 15. For example, in other embodiments provided by the present invention, the control component 14 is connected to the display device 16. Accordingly, sending alarm information by the control component 14 includes: sending alarm information to the display device 16 to control the display device 16 to display the alarm information. The display device 16 may be a monitor or an operation screen.

[0063] In this embodiment, the control component 14 controls the display device 16 to display alarm information, so that the operator can promptly detect information about the damage to the shock absorber 2 during the operation of the machinery.

[0064] Furthermore, the number of detection devices 13 is the same as that of the shock absorbers 2 and they correspond one-to-one. The control component 14 detects the floating amount based on the corresponding detection device 13, and the control display device 16 displays the number or location of the damaged shock absorber 2, so that the operator can clearly and quickly find the damaged shock absorber 2, thereby reducing the time required to troubleshoot the shock absorber 2.

[0065] In some embodiments of the present invention, the detection device 13 includes a displacement detection device. The rotating wheel 9 will inevitably experience displacement during the compression and damping process of the shock-absorbing device 2; therefore, the amount of movement of the rotating wheel 9 can be detected by the displacement detection device.

[0066] When the control component 14 determines that the movement of the rotating wheel 9 exceeds a movement threshold, it sends an alarm message to alert the operator that the shock absorber 2 is damaged. Specifically, when the movement of the rotating wheel 9 is too large, it indicates that the damping effect of the shock absorber 2 on the rotating wheel 9 has decreased or that it is not damping the rotating wheel 9 at all. In this case, the shock absorber 2 needs to be inspected, repaired, or replaced.

[0067] In some embodiments provided by the present invention, the displacement detection device is configured as a magnetostrictive displacement sensor 3.

[0068] The magnetostrictive displacement sensor 3 includes a measuring rod 301 and a magnetic ring 302. The magnetic ring 302 is fitted onto the outside of the measuring rod 301, and the measuring rod 301 is used to detect the position information of the magnetic ring 302. One of the magnetic ring 302 and the measuring rod 301 is connected to the mounting base 1, and the other is connected to the support shaft of the rotating wheel 9. For example, Figure 12 The diagram shows an example where the measuring rod 301 is connected to the mounting base 1, and the magnetic ring 302 is connected to the support shaft of the rotating wheel 9. It should be noted that the principle by which the magnetostrictive displacement sensor 3 detects the position information of the magnetic ring 302 is prior art and will not be elaborated upon further.

[0069] In this embodiment, when the rotating wheel 9 compresses the shock-absorbing device 2, the rotating wheel 9 moves relative to the mounting base 1, thereby driving the magnetic ring 302 to move relative to the measuring rod 301. The measuring rod 301 can detect the position information of the magnetic ring 302, and the control component 14 can obtain the amount of movement of the magnetic ring 302 based on the position information of the magnetic ring 302. The amount of movement of the magnetic ring 302 is the amount of movement of the rotating wheel 9.

[0070] Since the rotating wheel 9 is close to the ground, the environment in which the rotating wheel 9 is located is complex. By setting the magnetostrictive displacement sensor 3, the amount of movement of the rotating wheel 9 can be accurately obtained on the one hand, and it can adapt to harsh environments on the other hand. For example, even if the surface of the measuring rod 301 or the magnetic ring 302 is covered with dust or mud, it will not have too much impact on the position information of the magnetic ring 302 obtained by the magnetostrictive displacement sensor 3. Therefore, the magnetostrictive displacement sensor 3 has better environmental adaptability.

[0071] Of course, the displacement detection device is not limited to the magnetostrictive displacement sensor 3. For example, in other embodiments provided by the present invention, the displacement detection device is set as a pull wire sensor 5, which is connected to the mounting base 1, and the pull wire of the pull wire sensor 5 is connected to the support wheel of the rotating wheel 9.

[0072] In this embodiment, when the rotating wheel 9 compresses the shock absorption device 2, the rotating wheel 9 moves relative to the mounting base 1, thereby driving the extension and retraction of the pull wire sensor 5. The control component 14 can determine the amount of movement of the rotating wheel 9 based on the amount of extension and retraction of the pull wire.

[0073] By setting the pull-wire sensor 5, the movement of the rotating wheel 9 can be accurately obtained on the one hand, and it can adapt to harsh environments on the other hand. For example, even if the pull wire of the pull-wire sensor 5 is covered with dust or mud, it will not have too much impact on the pull-wire sensor 5 to obtain the extension and retraction of the pull wire. Therefore, the pull-wire sensor 5 has better environmental adaptability.

[0074] Of course, the displacement detection device is not limited to the pull-wire sensor 5. For example, in the embodiment provided by this invention, the displacement detection device is a laser rangefinder 4. The laser rangefinder 4 is mounted on the mounting base 1 and faces the rotating wheel 9.

[0075] In this embodiment, when the rotating wheel 9 compresses the shock absorption device 2, the rotating wheel 9 moves relative to the mounting base 1. The laser rangefinder 4 can detect the distance between the rotating wheel 9 and the mounting base 1, and the control component 14 can determine the amount of movement of the rotating wheel 9 based on the distance value.

[0076] With this configuration, the laser rangefinder 4 is directly mounted on the mounting base 1, directly measuring the distance between the mounted base 1 and the mounting base 1. The laser rangefinder 4 does not need to be connected to or in contact with the rotating wheel 9, making the position setting of the laser rangefinder 4 more flexible, the installation more convenient, and reducing interference problems.

[0077] Although the aforementioned displacement detection devices have reduced environmental adaptability, the rotating wheel 9 is close to the ground, and the soil and gravel on the ground will inevitably impact the displacement detection device. Therefore, in order to reduce the impact on the displacement detection device and extend its service life, refer to... Figures 11-14 As shown, in some embodiments of the present invention, the rotating wheel device further includes a protective component.

[0078] The protective assembly includes a fixed part and a movable part, which together form a sealed space. The movable part and the fixed part are movably connected to change the volume of the sealed space. The fixed part is connected to the mounting base 1, and the movable part is connected to the support shaft of the rotating wheel 9. When the rotating wheel 9 is displaced relative to the mounting base 1, the movable part also moves relative to the fixed part.

[0079] The displacement detection device is housed within the sealed space of the protective assembly. For example, the measuring rod 301 of the magnetostrictive displacement sensor 3 is connected to the fixed part, and the magnetic ring 302 is connected to the movable part. For example, the pull-wire sensor 5 is mounted on the fixed part, and the pull wire of the pull-wire sensor 5 is connected to the movable part. For example, the laser rangefinder 4 is mounted on the fixed part and faces the movable part to detect the distance between the movable part and the laser rangefinder 4.

[0080] This design, by incorporating protective components, prevents soil and gravel from impacting and damaging the displacement detection device, and avoids corrosive wastewater from corroding the device, thereby extending its service life.

[0081] Optionally, both the fixed part and the movable part are configured as housings 17, with the openings of the two housings 17 facing each other, and the two housings 17 are slidably fitted together. Furthermore, a sealing element is provided between the two housings 17 to improve the sealing effect between them.

[0082] refer to Figure 13 and Figure 14 As shown, optionally, the fixed part and the movable part are connected by a flexible sleeve 19. By providing a sealing sleeve between the fixed part and the movable part, a sealing effect can be formed between the fixed part and the movable part, while allowing lateral relative movement between the fixed part and the movable part, reducing the problem of jamming between the fixed part and the movable part.

[0083] Optionally, the flexible sleeve 19 can be a rubber sleeve or a waterproof cloth. The flexible sleeve 19 can be connected to the fixed part or the movable part by means of adhesive bonding or threaded fastener connection. When using threaded fasteners to connect the flexible sleeve 19, a pressure plate can be set between the head of the threaded fastener and the flexible sleeve 19 to ensure the compression effect of the flexible sleeve 19 and the sealing effect between the flexible sleeve 19 and the fixed part or the movable part.

[0084] refer to Figure 11 As shown, in some embodiments of the present invention, the rotating wheel device further includes a nozzle 18 for spraying air or water. Alternatively, two nozzles 18 may be configured, one spraying water and the other spraying air. During use, water is sprayed first to remove impurities, followed by air spraying for drying. The nozzle 18 is directed towards the displacement detection device to remove dust or sand from it. For example... Figure 11 The illustration shows an example where the nozzle 18 is directed toward the laser rangefinder 4 to prevent dust or sand from affecting the laser emission from the laser rangefinder 4. Furthermore, the nozzle 18 is housed within a protective assembly.

[0085] In some embodiments provided by the present invention, the shock absorption device 2 includes an elastic block 201, a connector 202, and a connecting seat 203.

[0086] Among them, the connecting seat 203 connects the elastic block 201 and the mounting seat 1, and the connecting piece 202 connects the elastic block 201 and the support shaft of the rotating wheel 9.

[0087] In this embodiment, as the rotating wheel 9 approaches the mounting base 1, the rotating wheel 9 presses against the elastic block 201. The elastic block 201 deforms and absorbs the kinetic energy of the rotating wheel 9, thereby providing a buffering effect on the rotating wheel 9.

[0088] In this embodiment, the shock absorber 2 has a small number of parts and no sliding or rotating structure. Therefore, the shock absorber 2 has a simple structure and low manufacturing cost.

[0089] refer to Figure 4 As shown, optionally, the connecting seat 203 is connected to the elastic block 201 via a threaded fastener. Specifically, the upper surface of the elastic block 201 is provided with a mounting groove for the connecting seat 203 to be inserted. The connecting seat 203 is inserted into the mounting groove, and the threaded fastener passes through the connecting seat 203 and the elastic block 201 and is connected to the nut, thereby connecting the connecting seat 203 and the elastic block 201. The surface of the elastic block 201 is also provided with a receiving groove for accommodating the nut, and a washer is provided between the nut and the receiving groove to reduce the squeezing effect of the nut on the elastic block 201.

[0090] Of course, the connector 203 is not limited to being connected to the elastic block 201 by threaded fasteners. For example, the connector 203 can also be bonded to the elastic block 201.

[0091] Optionally, the connecting seat 203 is connected to the mounting seat 1 by a threaded fastener. For example, the connecting seat 203 is provided with a stud, which passes through the mounting seat 1 and is connected to a nut.

[0092] Optionally, the number of connecting seats 203 is set to two. Both connecting seats 203 are used to connect the elastic block 201 and the mounting seat 1, thereby improving the connection strength between the elastic block 201 and the mounting seat 1.

[0093] Optionally, the elastic block 201 is a rubber block. Optionally, the elastic block 201 is a cylindrical structure. Two connecting seats 203 are respectively disposed on both sides of the central axis of the rubber block.

[0094] Optionally, the elastic block 201 is provided with a connecting hole 205 for the connector 202 to pass through. The connector 202 is a screw or bolt. The connector 202 passes through the connecting hole 205 on the elastic block 201 and is threadedly connected to the support shaft of the rotating wheel 9.

[0095] Optionally, each end of the support shaft of each rotating wheel 9 is connected to a corresponding elastic block 201 via a corresponding connector 202, and each elastic block 201 is connected to the mounting base 1 via a corresponding connector 203. This arrangement provides elastic blocks 201 at both ends of the support shaft, thereby providing better support and shock absorption for the rotating wheel 9.

[0096] In some embodiments provided by the present invention, the elastic block 201 is provided with a through hole 204, the through hole 204 and the connector 202 extend in the same direction, that is, the through hole 204 and the connecting hole 205 extend in the same direction, and the through hole 204 penetrates the elastic block 201.

[0097] In this embodiment, by providing a through hole 204 on the elastic block 201, the deformation capacity of the elastic block 201 under force can be improved, thereby improving the force performance of the elastic block 201 and enhancing the buffering effect on the rotating wheel 9.

[0098] Optionally, the number of through holes 204 is at least two, and the at least two through holes 204 are distributed along the circumference of the connector 202. Further, the through holes 204 are distributed along the force direction of the rotating wheel 9, for example... Figure 3 and Figure 4 As shown, taking the support roller 902 as an example, the force direction of the support roller 902 is vertical, so the through holes 204 are distributed along the vertical direction. By distributing the through holes 204 along the force direction of the rotating wheel 9, the amount of movement of the rotating wheel 9 in the force direction can be increased, thereby increasing the buffering effect of the elastic element 208 on the rotating wheel 9.

[0099] Of course, the shock absorption device 2 is not limited to the form of the shock absorption block described above. For example, in other embodiments provided by the present invention, the shock absorption device 2 includes a cylinder 206, a torsion shaft 207, an elastic element 208, and a connecting plate 209.

[0100] Both the cylinder 206 and the torsion shaft 207 are configured as polygonal columnar structures, with the torsion shaft 207 rotatably disposed inside the cylinder 206. Specifically, the cylinder 206 and the torsion shaft 207 have the same number of sides, for example... Figure 7 and Figure 8 Both the cylinder 206 and the torsion shaft 207 are configured as quadrilateral columnar structures. The inner cross-section of the cylinder 206 is larger than the outer cross-section of the torsion shaft 207, so that the torsion shaft 207 can rotate inside the cylinder 206.

[0101] An elastic element 208 is disposed between the cylinder 206 and the torsion shaft 207, and the torsion shaft 207 compresses the elastic element 208 during rotation. Optionally, the elastic element 208 is a strip-shaped structure, and the elastic element 208 can be a rubber component. Each side of the torsion shaft 207 corresponds to one elastic element 208. Figure 7For example, each of the four sides of the torsion shaft 207 corresponds to an elastic element 208. The four elastic elements 208 are distributed at the four vertices of the cylinder 206. During the rotation of the torsion shaft 207, the torsion shaft 207 and the cylinder 206 squeeze the elastic element 208 between them, thereby hindering and buffering the rotation of the torsion shaft 207.

[0102] The connecting plate 209 connects the torsion shaft 207 and the support shaft of the rotating wheel 9. (Reference) Figure 6 and Figure 9 As shown, the line connecting the centers of the rotating wheel 9 and the torsion shaft 207 is inclined relative to the height direction of the rotating wheel 9.

[0103] In this embodiment, as the rotating wheel 9 approaches the mounting base 1, the kinetic energy of the rotating wheel 9 is transmitted to the torsion shaft 207 through the connecting plate 209, thereby driving the torsion shaft 207 to rotate. The torsion shaft 207 and the cylinder 206 squeeze the elastic member 208 between them, and the elastic member 208 deforms to absorb the kinetic energy of the torsion shaft 207, thereby creating a buffering effect on the rotating wheel 9.

[0104] Optionally, the connecting plate 209 can be connected to the support shaft by a threaded fastener, that is, the threaded fastener passes through the connecting plate 209 and is threadedly connected to the support shaft.

[0105] Optionally, the cylinder 206 can be connected to the mounting base 1 by welding or threaded fasteners.

[0106] Furthermore, both ends of the torsion shaft 207 are connected to the two ends of the support shaft of the rotating wheel 9 via corresponding connecting rods. This arrangement allows the shock absorption device 2 to provide better support and cushioning for the support shaft.

[0107] refer to Figure 9 As shown, in some embodiments provided by the present invention, the connecting plate 209 is provided with two rotating wheels 9, and the two rotating wheels 9 are respectively arranged on both sides of the torsion shaft 207.

[0108] In this embodiment, when either of the two rotating wheels 9 rises, it can drive the torsion shaft 207 to rotate. In this way, a shock-absorbing device 2 can provide a buffering and shock-absorbing effect for the two rotating wheels 9, thereby improving the structural compactness of the rotating wheel device.

[0109] In some embodiments of the present invention, for the damping device 2 configured as a torsion shaft 207, the detection device 13 includes an angle detection device for detecting the rotation angle of the torsion shaft 207 or the connecting plate 209. The angle detection device is connected to the control component 14, which sends an alarm message based on the rotation angle. Specifically, the control component 14 sends an alarm message when it determines that the rotation angle is greater than a preset angle threshold.

[0110] In this embodiment, as the rotating wheel 9 approaches the mounting base 1, the rotating wheel 9 drives the torsion shaft 207 to rotate through the connecting plate 209. Therefore, the rotation angle of the torsion shaft 207 or the connecting plate 209 can also be used to determine whether the shock absorption device 2 is damaged.

[0111] Optionally, the angle detection device can be an encoder, for example, an encoder mounted on the cylinder 206, with the encoder's input shaft connected to the torsion shaft 207 via a flexible coupling such as a universal joint. The angle detection device can also be a gyroscope or inclinometer to detect the angle of the connecting plate 209.

[0112] This invention also provides a tracked device.

[0113] Specifically, the track device includes a track 11 and a rotating wheel device as described above, wherein the rotating wheel 9 is disposed on the inner side of the track 11 and abuts against the track 11.

[0114] The track system includes the rotating wheel system, and therefore includes all the advantages of the rotating wheel system mentioned above, which will not be elaborated here.

[0115] Optionally, the rotating wheel device includes a support wheel 902 and a guide wheel 901. There are multiple support wheels 902. At least one of the support wheels 902 and the guide wheel 901 adopts the shock absorption device 2 in the form of the elastic block 201 or the shock absorption device 2 in the form of the torsion shaft 207.

[0116] Optionally, the track assembly also includes a drive wheel 8, which is mounted on a mounting frame and used to drive the track 11. The track assembly also includes a tensioning device 7 and a tensioning wheel 6. Both the tensioning wheel 6 and the tensioning device 7 are mounted on a mounting frame, and the tensioning device 7 is used to drive the tensioning wheel 6 to abut against the track 11, thereby tightening the track 11.

[0117] Optionally, the tensioning device 7 includes a tensioning cylinder 701, a spring 702, a sliding seat 703, and a limiting nut 704. The tensioning cylinder 701 is configured as a hydraulic cylinder. The cylinder body is provided with a guide post 705 and a flange 706. The sliding seat 703 is slidably connected to the mounting base 1, and the sliding seat 703 is also slidably engaged with the guide post 705. The limiting nut 704 is threadedly connected to the guide post 705 to limit the sliding seat 703 and prevent it from dislodging from the guide post 705. One end of the spring 702 abuts against the flange 706, and the other end abuts against the sliding seat 703. The tensioning wheel 6 is disposed on the sliding seat 703, and the piston rod of the hydraulic cylinder is connected to the mounting base 1. When it is necessary to tension the track 11, the hydraulic cylinder extends, and the cylinder body drives the sliding seat 703 through the spring 702, so that the tensioning wheel 6 on the sliding seat 703 tensions the track 11. Spring 702 can also buffer the tensioner 6, preventing the tensioner 6 from impacting the oil cylinder.
