[0006] According to one aspect of this disclosure, an anti-tipping device for engineering machinery is provided, comprising:

[0007] Support base;

[0008] Support components;

[0009] A first drive member, connecting the support base and the support assembly, is configured to drive the support assembly to move relative to the support base to adjust the ground clearance of the support assembly; and

[0010] The wheel is movably mounted on the support assembly and has an exposed state and a concealed state. In the exposed state, at least part of the wheel is located outside the support assembly and can contact the ground. In the concealed state, the wheel is located inside the support assembly so that the support assembly can contact the ground.

[0011] In some embodiments, the extension length of the wheel relative to the support assembly is adjustable.

[0013] In some embodiments, the support assembly has a receiving cavity with a first opening through which the wheel enters and exits the receiving cavity.

[0014] In some embodiments, the anti-tipping device further includes a connecting shaft, a wheel body is mounted on the connecting shaft, and the cavity wall of the receiving cavity is provided with a limiting hole with a second opening, through which the connecting shaft enters and exits the limiting hole.

[0015] In some embodiments, the limiting hole is elongated, and the length direction of the limiting hole is parallel to the extension and retraction direction of the wheel body relative to the support assembly.

[0016] In some embodiments, the anti-rollover device further includes a first link and a second link, the two ends of the first link being rotatably connected to a support base and a support assembly, respectively, and the two ends of the second link being rotatably connected to a support base and a support assembly, respectively, and the support base, the first link, the support assembly and the second link are connected to form a parallelogram mechanism.

[0017] In some embodiments, the first link, the second link, and the first drive member are staggered so that the projections of the first link, the second link, and the first drive member on the support base do not overlap when the support assembly is retracted relative to the support base.

[0018] In some embodiments, the two ends of the first drive member are rotatably connected to the support base and the support assembly, respectively.

[0019] In some embodiments, the support component includes a contact surface, and the wheel is movably disposed relative to the contact surface, wherein the contact surface is capable of contacting the ground in a concealed state.

[0020] In some embodiments, the anti-tipping device for construction machinery further includes a tilt sensor and a controller. The tilt sensor is configured to detect the center of gravity offset angle of the construction machinery. The controller is signal-connected to the tilt sensor and the first drive member. The controller is configured to control the first drive member to drive the support assembly to unfold or retract based on the center of gravity offset angle detected by the tilt sensor.

[0021] In some embodiments, the anti-tipping device for construction machinery further includes a tracked walking mechanism, with a support mounted on the outside of the tracked walking mechanism.

[0046] The technical solutions in the embodiments of this disclosure will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0047] In the description of this disclosure, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this disclosure.

[0048] like Figures 1 to 5As shown, in some embodiments of the anti-tipping device for engineering machinery provided in this disclosure, the anti-tipping device includes a support base 1, a support assembly 2, a first drive member 3, and a wheel 4. The first drive member 3 connects the support base 1 and the support assembly 2. The first drive member 3 is configured to drive the support assembly 2 to move relative to the support base 1 to adjust the ground clearance of the support assembly 2. The wheel 4 is movably mounted on the support assembly 2 and has an exposed state and a concealed state. In the exposed state, at least a portion of the wheel 4 is located outside the support assembly 2 and can contact the ground; in the concealed state, the wheel 4 is located inside the support assembly 2 so that the support assembly 2 can contact the ground.

[0049] As a supporting component for the first driving member 3 and the supporting assembly 2, the support base 1 can effectively ensure the stability of the supporting assembly 2 during its movement relative to the support base 1.

[0050] The support base 1 can be installed on a fixed component of the construction machinery, such as the chassis. When the construction machinery includes a tracked walking mechanism 8, the support base 1 can be installed on the tracked walking mechanism 8.

[0051] Support component 2 is the core component for auxiliary support and anti-tipping. Under the driving action of the first driving component 3, support component 2 moves relative to support base 1. After moving relative to support base 1, the ground clearance of support component 2 changes, thereby adjusting its support state. When the ground clearance of support component 2 is greater than zero, support component 2 does not provide support; when the ground clearance of support component 2 is zero, i.e., when support component 2 is on the ground, support component 2 provides support, assisting the construction machinery body in improving the overall stress distribution and enhancing the overall stability and anti-tipping effect of the construction machinery.

[0052] The first driving member 3 is connected to the support base 1 and the support assembly 2 at both ends. Specifically, the fixing part of the first driving member 3 is connected to the support base 1, and the driving part is connected to the support assembly 2; or, the driving part of the first driving member 3 is connected to the support base 1, and the fixing part is connected to the support assembly 2.

[0053] The first driving component 3 can be a hydraulic cylinder, a pneumatic cylinder, or a motor, etc.

[0054] Wheel 4 is movably mounted on support assembly 2. For example... Figure 4 and Figure 5 As shown, in the exposed state, at least a portion of the wheel 4 is located outside the support assembly 2. After the ground clearance of the support assembly 2 decreases, the wheel 4, being at least partially exposed to the outside of the support assembly 2, first contacts the ground to provide support; as Figure 3 As shown, in the hidden state, the wheel 4 is located inside the support component 2. Therefore, after the height of the support component 2 from the ground decreases, the support component 2 first contacts the ground and assumes the supporting function.

[0055] When support component 2 contacts the ground, it provides support for the construction machinery, thereby effectively adjusting the overall stress on the machinery, improving its overall stability, and preventing it from tipping over. When wheel 4 contacts the ground, the friction between the anti-tipping device and the ground is rolling friction. When the construction machinery gets stuck in mud or other difficulties, wheel 4 can be positioned differently from the location of the machinery's own walking mechanism, thus assisting the machinery in quickly getting out of trouble.

[0056] In this embodiment of the disclosure, by setting a movable wheel 4 on the support component 2, the wheel 4 can have an exposed state and a hidden state, so that the anti-rollover device can have at least two functions at the same time: anti-rollover and assisting in getting out of trouble. This effectively expands the scope of application of the anti-rollover device and improves the adaptability of engineering machinery to complex road conditions.

[0057] In related technologies, the chassis of lifting machinery is equipped with outrigger structures. Before operation, these outrigger structures need to be extended and brought into contact with the ground. At this point, the traveling mechanism of the lifting machinery is lifted off the ground, and the entire lifting machinery is supported by the outrigger structures. The main function of this outrigger structure is to provide stable support for the lifting machinery during operation, thereby improving its stability and safety. However, the outrigger structure itself does not have a traveling function; it needs to be retracted when the lifting machinery needs to be moved. Therefore, this type of outrigger structure cannot meet the needs of assisting in getting out of trouble.

[0058] In this embodiment of the disclosure, in the exposed state, the proportion of the wheel 4 located outside the support component 2 can be referenced by the fact that the wheel 4 contacts the ground before the support component 2.

[0059] The position of the wheel 4 relative to the support component 2 may include an exposed position and a hidden position, or multiple intermediate transition positions.

[0060] In some embodiments, the extension length of the wheel 4 relative to the support assembly 2 is adjustable.

[0061] By setting the extension length of the wheel 4 relative to the support component 2 to be adjustable, the extension length of the wheel 4 relative to the support component 2 can be flexibly adjusted according to the needs of the scenario, rather than being limited to the exposed position and the hidden position, which effectively improves the applicability of the anti-tipping device.

[0062] In some embodiments, the anti-rollover device further includes a second drive member 5, which connects the support assembly 2 and the wheel 4, and is configured to drive the wheel 4 to extend or retract relative to the support assembly 2.

[0063] By setting the second driving component 5, the wheel 4 can be driven to extend or retract relative to the support component 2, thereby adjusting the extension length of the wheel 4 relative to the support component 2 to meet different needs in different scenarios.

[0064] The second driving component 5 can be a hydraulic cylinder, a pneumatic cylinder, or a motor, etc.

[0065] In some embodiments, the fixing part of the second drive member 5 is mounted on the support assembly 2, and the drive part is connected to the wheel body 4.

[0066] like Figure 6 As shown, in some embodiments, the support component 2 is provided with a receiving cavity 212 having a first opening 211, through which the wheel 4 enters and exits the receiving cavity 212.

[0067] By providing a receiving cavity 212 on the support component 2, a receiving space can be provided for the wheel body 4. In the hidden state, the wheel body 4 is hidden inside the receiving cavity 212.

[0068] By setting the first opening 211, the wheel body 4 can freely enter and exit the receiving cavity 212, realizing the switching between the exposed state and the hidden state of the wheel body 4.

[0069] In some embodiments, the receiving cavity 212 is disposed at the bottom of the support assembly 2, and the first opening 211 faces downward, so that the wheel 4 can be exposed or abnormally moved up and down.

[0070] like Figure 5 As shown, in some embodiments, the anti-tipping device further includes a connecting shaft 6, the wheel body 4 is mounted on the connecting shaft 6, and the cavity wall of the receiving cavity 212 is provided with a limiting hole 214 having a second opening 213, through which the connecting shaft 6 enters and exits the limiting hole 214.

[0071] By setting the connecting shaft 6 and the limiting hole 214, the movement path of the wheel body 4 can be guided and restricted, thereby improving the movement accuracy of the wheel body 4.

[0072] By setting the second opening 213, the connecting shaft 6 can freely enter and exit the limiting hole 214, thereby driving the wheel 4 to precisely switch between the exposed state and the hidden state.

[0073] In some embodiments, the second opening 213 and the first opening 211 are oriented in the same direction so that the wheel 4 and the connecting shaft 6 can move synchronously.

[0074] In some embodiments, the limiting hole 214 is elongated, and the length direction of the limiting hole 214 is parallel to the extension and retraction direction of the wheel body 4 relative to the support component 2.

[0075] By setting the limiting hole 214 to an elongated shape, an elongated movement space can be provided for the movement of the connecting shaft 6, which can both guide the connecting shaft 6 and effectively limit the skewness of the connecting shaft 6 during movement.

[0076] In some embodiments, the support component 2 is provided with a through hole 29, one end of the second drive member 5 is connected to the support component 2, and the other end passes through the through hole 29 and is connected to the wheel body 4.

[0077] By setting through holes 29, structural interference can be avoided, and the movement path of the second driving component 5 can be guided and restricted to prevent the second driving component 5 from shaking during extension and retraction.

[0078] In some embodiments, the support component 2 is generally rectangular. This shape has a larger contact area compared to the outrigger structure on a crane, which helps to improve support stability.

[0079] like Figure 5 As shown, in some embodiments, the anti-rollover device includes multiple wheels 4 and a connecting frame 9. The multiple wheels 4 are mounted on the connecting frame 9, and the second drive component 5 connects the support assembly 2 and the connecting frame 9.

[0080] By setting up a connecting frame 9 and mounting multiple wheels 4 on the connecting frame 9, the connecting frame 9 can be driven to move, thereby driving multiple wheels 4 to move synchronously and improving the synchronicity of the movement of multiple wheels 4.

[0081] Meanwhile, a receiving space can be set inside the connecting frame 9, and part of the structure of the wheel body 4 is hidden in the receiving space. In this way, the connecting frame 9 can protect the wheel body 4 and extend the service life of the wheel body 4.

[0082] In some embodiments, the anti-tipping device further includes a linkage assembly 7, which is rotatably connected to the support base 1 and the support assembly 2 to form a parallelogram mechanism.

[0083] By setting the linkage assembly 7 and forming a parallelogram mechanism with the support base 1 and the support assembly 2, the movement of the support assembly 2 relative to the support base 1 can be guided and restricted. At the same time, the swaying of the support assembly 2 during the movement can be reduced, and the stability of the support assembly 2 relative to the support base 1 during the movement can be improved.

[0084] In some embodiments, the linkage assembly 7 includes a first linkage 71 and a second linkage 72. The two ends of the first linkage 71 are rotatably connected to the support base 1 and the support assembly 2, respectively, and the two ends of the second linkage 72 are rotatably connected to the support base 1 and the support assembly 2, respectively.

[0085] By setting the first link 71 and the second link 72, they can be connected with the support base 1 and the support assembly 2 to form a parallelogram mechanism, which can improve the swaying problem of the support assembly 2 during movement.

[0086] In some embodiments, the first link 71, the second link 72, and the first drive member 3 are staggered so that the projections of the first link 71, the second link 72, and the first drive member 3 on the support base 1 do not overlap when the support assembly 2 is retracted relative to the support base 1.

[0087] By staggering the arrangement of the first link 71, the second link 72, and the first drive member 3, the projections of the first link 71, the second link 72, and the first drive member 3 on the support base 1 can be made non-overlapping and non-intersecting when the support assembly 2 is retracted relative to the support base 1. This allows the first link 71, the second link 72, and the first drive member 3 to be arranged flat between the support base 1 and the support assembly 2, reducing the gap between the support assembly 2 and the support base 1 after retraction. At the same time, it can also effectively prevent interference between the first link 71, the second link 72, and the first drive member 3 during the retraction of the support assembly 2.

[0088] like Figure 2 and Figure 7 As shown, in some embodiments, the support base 1 and the support component 2 are arranged opposite to each other. The direction from the support base 1 to the support component 2 is defined as the first direction. In the second direction perpendicular to the first direction, the first link 71, the second link 72 and the first drive member 3 are arranged in a staggered manner.

[0089] In some embodiments, the two ends of the first driving member 3 are rotatably connected to the support base 1 and the support assembly 2, respectively.

[0090] By configuring the first driving member 3 to be rotatably connected to the support base 1 and the support assembly 2 respectively, the first driving member 3 can rotate relative to the support base 1 and the support assembly 2. This allows the support assembly 2 to maintain its posture during movement relative to the support base 1, which helps to keep the posture of the support assembly 2 relative to the ground fixed. This ensures that the part of the support assembly 2 in contact with the ground remains unchanged, preventing the support stability from being affected by different contact points when the support assembly 2 is grounded at different heights relative to the support base 1.

[0091] The support component 2 is movable relative to the support base 1, so the support component 2 has a retracted state close to the support base 1 and an extended state away from the support base 1. By setting the first drive member 3 to be rotatably connected to the support base 1 and the support component 2 respectively, the posture of the support component 2 relative to the support base 1 can remain unchanged in the retracted state and the extended state.

[0092] The support component 2 maintains a fixed posture during its movement relative to the support base 1. This can be understood as the support component 2 itself not flipping relative to the support base 1, and the support component 2 can always remain upright during the movement.

[0093] In addition, when the ground is uneven, the support component 2 can achieve contact with the ground by rotating relative to the first driving component 3 after grounding, thus ensuring stable grounding and reliable support.

[0094] In some embodiments, the support component 2 includes a contact surface, and the wheel 4 is movably disposed relative to the contact surface, wherein the contact surface is able to contact the ground in a hidden state.

[0095] The contact between support component 2 and the ground is a surface contact. Compared with point contact and line contact, surface contact can greatly improve the stability of contact and support.

[0096] like Figure 1 and Figure 2 As shown, in some embodiments, the anti-tipping device for construction machinery also includes a tracked walking mechanism 8, with a support seat 1 installed on the outside of the tracked walking mechanism 8.

[0097] The support base 1 is installed on the outside of the tracked walking mechanism 8, which will not occupy the internal space of the construction machinery, and at the same time, it is convenient for the support component 2 connected to the support base 1 to unfold for support.

[0098] In some embodiments, the anti-tipping device for construction machinery further includes a tilt sensor and a controller. The tilt sensor is configured to detect the center of gravity offset angle of the construction machinery. The controller is signal-connected to the tilt sensor and the first drive member 3. The controller is configured to control the first drive member 3 to drive the support assembly 2 to unfold or retract based on the center of gravity offset angle detected by the tilt sensor.

[0099] By setting up an tilt sensor and a controller, the automatic deployment and retraction of the support assembly 2 can be achieved. When the tilt sensor detects that the center of gravity offset angle of the construction machinery reaches a preset value, the controller controls the first drive component 3 to drive the support assembly 2 to deploy, thereby supporting the construction machinery, adjusting the force on the construction machinery, and restoring its balance. When the center of gravity offset angle of the construction machinery is less than the preset value, the controller can control the first drive component 3 to remain stationary, keeping the support assembly 2 in the retracted state.

[0100] Based on the aforementioned anti-tipping device for construction machinery, this disclosure also proposes a type of construction machinery that includes the aforementioned anti-tipping device for construction machinery.

[0101] The positive technical effects of the anti-tipping devices for construction machinery in the above embodiments are also applicable to construction machinery, and will not be repeated here.

[0102] The following is in conjunction with the appendix Figures 1 to 13 The structure and working process of the anti-tipping device for construction machinery and an embodiment of the construction machinery provided in this disclosure are described below:

[0103] like Figure 1 , Figure 2 and Figure 7 As shown, the anti-rollover device includes a support base 1, a support assembly 2, a first drive member 3, a linkage assembly 7, and a tracked walking mechanism 8. The support base 1 is installed on the outside of the tracked walking mechanism 8, and one end of the first drive member 3 is rotatably connected to the support base 1, while the other end is rotatably connected to the support assembly 2.

[0104] The linkage assembly 7 includes a first link 71 and a second link 72, which are rotatably connected between the support base 1 and the support assembly 2, respectively.

[0105] The anti-rollover device also includes wheels 4 movably mounted on the support assembly 2. For example... Figure 3 As shown, wheel 4 is in a hidden state; Figure 4 As shown, a portion of wheel 4 is exposed; as Figure 5 As shown, wheel 4 is fully exposed.

[0106] The support base 1 has a flat plate structure. Two support bases 1 are installed on the left and right sides of the tracked walking mechanism 8, respectively. The support assembly 2 has a frame structure.

[0107] like Figure 6 As shown, the support assembly 2 includes a bracket 21, uprights 22, a crossbeam 23, and support columns 24. The bracket 21 is located at the bottom, and two uprights 22 are respectively installed on the top surface of the bracket 21. The two uprights 22 are hollow cuboid structures. The crossbeam 23 horizontally connects the two uprights 22. Two support columns 24 connect the crossbeam 23 and the top surface of the bracket 21. The crossbeam 23 can be a hollow cylindrical structure. The support columns 24 can be hollow cylinders or cuboid structures.

[0108] Two first mounting members 25 are provided on the side of the crossbeam 23 near the support base 1. The two first mounting members 25 are respectively connected to the fixing parts of the two first driving members 3. The first mounting member 25 includes two ear plates with holes. The driving part of the first driving member 3 is inserted between the two ear plates. The connecting member passes through the holes on the ear plates and the fixing parts to realize the rotatable connection between the driving part and the first mounting member 25. The structure of the two ear plates can effectively alleviate the sway of the first driving member 3 relative to the support base 1.

[0109] The two columns 22 are respectively provided with a second mounting part 26 and a third mounting part 27 on the side near the support base 1. The second mounting part 26 is connected to the first connecting rod 71, and the third mounting part 27 is connected to the second connecting rod 72.

[0110] The second mounting component 26 and the third mounting component 27 are arranged vertically. The second mounting component 26 is located above the third mounting component 27. The first connecting rod 71 is located above the second connecting rod 72.

[0111] In this embodiment, the second mounting member 26 and the third mounting member 27 are aligned vertically. Furthermore, both the second mounting member 26 and the third mounting member 27 are single-ear plate structures. The first connecting rod 71 is connected to the outside of the second mounting member 26, and the second connecting rod 72 is connected to the inside of the third mounting member 27. This allows the first connecting rod 71 and the second connecting rod 72 to be offset in the lateral direction, which also helps to alleviate the swaying of the first connecting rod 71 and the second connecting rod 72.

[0112] Of course, in other embodiments, the second mounting member 26 and the third mounting member 27 may also adopt a double-ear plate structure.

[0113] like Figure 1 and Figure 2 As shown, the support base 1 has three sixth mounting parts 11 on the side near the support assembly 2. The three sixth mounting parts 11 are respectively connected to the first connecting rod 71, the second connecting rod 72 and the fixing part of the first driving member 3.

[0114] The anti-rollover device also includes a second drive component 5, a connecting shaft 6, and a connecting frame 9.

[0115] Two fourth mounting parts 28 are provided below the crossbeam 23, and the two fourth mounting parts 28 are respectively connected to the driving parts of the two second driving parts 5.

[0116] The bracket 21 is a hollow cuboid structure with openings on three sides. The top plate of the bracket 21 has a through hole 29. The second driving member 5 passes through the through hole 29, and the fixing part of the second driving member 5 is connected to the connecting frame 9.

[0117] like Figure 5 As shown, the connecting frame 9 includes a connecting frame body 91 and a fifth mounting component 92. The structure of the connecting frame body 91 is similar to that of the bracket 21. The connecting frame body 91 is a hollow cuboid structure with openings on three sides. Part of the wheel 4 is hidden inside the connecting frame body 91, and part is exposed outside the connecting frame body 91. The wheel 4 is fixedly mounted on the connecting frame body 91 via a connecting shaft 6.

[0118] The fifth mounting component 92 is disposed on the top surface of the connecting frame body 91, and the fifth mounting component 92 is connected to the fixing part of the second driving component 5.

[0119] The bottom opening of the bracket 21 is a first opening 211, and the interior of the bracket 21 is a receiving cavity 212. Both the front and rear side plates of the bracket 21 are provided with limiting holes 214, and the bottom opening of the limiting holes 214 is a second opening 213. The connecting frame 9 enters and exits the receiving cavity 212 through the first opening 211.

[0120] The fourth mounting component 28, the fifth mounting component 92, and the sixth mounting component 11 can all be double-ear plate structures or single-ear plate structures.

[0121] like Figure 7 As shown, the first link 71, the second link 72 and the first drive member 3 are staggered in the lateral direction to reduce the distance between the support assembly 2 and the support base 1 after the support assembly 2 is retracted.

[0122] like Figure 8 and Figure 9 As shown, both the first connecting rod 71 and the second connecting rod 72 are elongated plate-like structures. The first connecting rod 71 has a first connecting hole 711 and a second connecting hole 712, which are respectively connected to the support base 1 and the support assembly 2. The second connecting rod 72 has a third connecting hole 721 and a fourth connecting hole 722, which are respectively connected to the support base 1 and the support assembly 2.

[0123] like Figures 10 to 13 As shown, the construction machinery includes a construction machinery body 10 and a tracked walking mechanism 8, with a support base 1 and a support assembly 2 installed on the outside of the tracked walking mechanism 8.

[0124] Figure 10 and Figure 11 These are side views of support component 2 retracting and unfolding, respectively. Figure 12 and Figure 13 These are the rear views of support component 2 when it is retracted and when it is extended.

[0125] Working process: When the anti-rollover device needs to extend, the first driving component 3 needs to be extended first, which in turn drives the first connecting rod 71 and the second connecting rod 72 to move through the parallelogram mechanism, so that the support component 2 extends outward relative to the support base 1, as shown below. Figure 11 and Figure 13 As shown. When the anti-rollover device needs to be retracted, the first drive component 3 needs to be retracted first, and then the first link 71 and the second link 72 are moved through the parallelogram mechanism to realize the retraction of the support component 2 relative to the support base 1, as shown. Figure 10 and Figure 12 As shown.

[0126] In this embodiment of the disclosure, the engineering machinery can be rescue machinery or forestry machinery, and is particularly suitable for engineering machinery that includes a tracked walking mechanism, such as a forest clearing machine.

[0127] For forest clearing machines, the anti-tipping device embodiments provided in this disclosure can at least handle the following scenarios:

[0128] 1. In the event of a vehicle suddenly overturning when encountering potholes while driving, the anti-overturning device embodiment provided in this disclosure can control the extension of the support components through a controller to quickly prevent instability from occurring;

[0129] 2. When traversing roads with steep slopes and high risk of lateral tilting, the anti-rollover device embodiments provided in this disclosure can maintain the lateral stability of the vehicle on the slope during driving by extending the support components and wheels;

[0130] 3. When one track of the construction machinery needs to operate at the edge of a ditch, the anti-tipping device embodiment provided in this disclosure can extend the support component to cross the ditch, providing additional safety assurance;

[0131] 4. When grabbing and moving heavy timber, when the grab arm extends too far and the load reaches its limit, a huge overturning moment will be generated. The anti-overturning device embodiment provided in this disclosure can provide stable support by extending the support component.

[0132] 5. When operating in extremely soft and uneven forest land, the ground conditions in the forest land are complex, with felling roots, branches, mud pits, and extremely uneven support points. One track may be pressed on a solid felling root, while another is stuck in a soft humus layer. The anti-tipping device embodiment provided in this disclosure can be supported at a position different from the location of the track by extending the support component.

[0133] 6. When operating in areas with dead or fallen trees, the ground is covered with a large number of dead trees and branches, and the tracks are easily stuck in the gaps between the fallen trees, or the machine body may be suspended on one side due to the rolling of the fallen trees. The anti-tipping device embodiment provided in this disclosure can extend the support components and wheels to assist in getting out of trouble and achieve active self-rescue.

[0134] In the embodiments of this disclosure, the controller may be a general-purpose processor, a programmable logic controller (PLC), a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, or any suitable combination thereof for performing the functions described in this disclosure.

[0135] The description of the various embodiments above tends to emphasize the differences between the various embodiments. The similarities or similarities between them can be referred to, and for the sake of brevity, they will not be repeated here.

[0136] Those skilled in the art will understand that, in the methods described in the specific embodiments, the order in which the steps are written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of each step should be determined by its function and possible internal logic.

[0137] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and not to limit them; although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this disclosure or equivalent substitutions can still be made to some technical features without departing from the principles of this disclosure, and such modifications and equivalent substitutions should all be covered within the scope of the technical solutions claimed in this disclosure.
