Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, and in particular to a track plate, track device and working machinery. Background Technology

[0002] With the diversified application and development of construction machinery, the structure of construction machinery is becoming more refined, user-friendly, and convenient to operate and maintain. For example, taking excavators as an example, the undercarriage of an excavator includes a track system. Power is transmitted to the tracks using the friction between the chains and wheels on the tracks, thus enabling the excavator to move. During construction, to meet operational needs, excavators often operate in muddy and uneven terrain. In such conditions, the tracks are prone to sinking, causing instability in the excavator's movement. It is necessary to widen the surface area of ​​the tracks to reduce the pressure on the ground and prevent the tracks from sinking. At the same time, increasing the surface area of ​​the tracks also increases friction, allowing the excavator to pass more safely and stably on slopes and uneven terrain.

[0003] Currently, it's possible to equip two excavators with different track widths. For operations in muddy and uneven terrain, the excavator with wider tracks can be selected directly, but this is relatively expensive. Alternatively, the excavator's tracks can be configured to be widened; when working in muddy or uneven terrain, the tracks can be widened. However, in existing technologies, widening the tracks requires specialized tools, making the operation difficult. Furthermore, when widening the tracks is not needed, the widening plates must be completely removed from the tracks and transported using a separate vehicle, which is also costly.

[0004] Therefore, how to solve the problem of the difficulty and high cost of widening tracks in the existing technology has become an important technical problem to be solved by those skilled in the art. Summary of the Invention

The limiting groove is connected to the vertical groove.

[0013] The slider is also adapted to slide along the limiting groove.

[0014] According to a track plate provided by the present invention, a first limiting part is provided on the side of the transverse slide groove away from the vertical slide groove along the thickness direction of the base plate. The first limiting part is adapted to restrict the slider to move along the thickness direction of the base plate within the transverse slide groove.

[0015] Along the length of the base plate, a second limiting part is provided on the side of the vertical slide groove away from the horizontal slide groove. The second limiting part is adapted to restrict the displacement of the slider within the vertical slide groove along the length of the base plate.

[0016] According to a track plate provided by the present invention, a first connecting hole is provided on the bottom plate, and a second connecting hole is provided on the panel. When the panel is in the first position, the axis of the first connecting hole coincides with the axis of the second connecting hole, and the fastener is adapted to connect with the first connecting hole and the second connecting hole.

[0017] And / or, the base plate is provided with a third connecting hole, and the panel is provided with a fourth connecting hole. When the panel is in the second position, the axis of the third connecting hole coincides with the axis of the fourth connecting hole, and the fastener is adapted to connect with the third connecting hole and the fourth connecting hole.

[0018] According to a track plate provided by the present invention, reinforcing ribs are provided on the working surface side of the bottom plate and the working surface side of the panel. The reinforcing ribs extend along the length direction of the bottom plate, and the plane where the reinforcing ribs are located is set at an angle to the working surface of the bottom plate and the plane where the reinforcing ribs are located is set at an angle to the working surface of the panel.

[0019] A clearance groove is provided on the opposite side of the working surface of the panel, and the clearance groove is adapted to avoid the reinforcing rib on the base plate.

[0020] According to a track plate provided by the present invention, a handrail is provided on the panel, and when the panel is in the second position, the handrail is located on the side of the panel away from the bottom plate.

[0021] According to a track plate provided by the present invention, the bottom plate is provided with a fifth connecting hole, the fifth connecting hole being adapted to connect with a track link, the track link being located on the opposite side of the working surface side of the bottom plate;

[0022] And / or, the bottom plate is provided with connecting portions at both ends along its own width direction, the connecting portions being adapted to connect with the bottom plate of the adjacent track plate.

[0025] The track plate provided by this invention includes a base plate, a face plate, and fasteners. The thickness direction of the base plate is consistent with the thickness direction of the track plate, and the length direction of the base plate is consistent with the length direction of the track plate. When multiple track plates are connected to form a track, the length direction of the track plate is the width direction of the track. One of the two surfaces of the base plate distributed along its own thickness direction is the working surface of the base plate. The face plate is slidably connected to the base plate, and the face plate can slide between a first position and a second position. When the face plate slides to the first position, the face plate is located on the working surface side of the base plate, and the face plate overlaps with the base plate. At this time, the fastener is used to fix the face plate and the base plate together. The surface of the face plate away from the base plate is the working surface of the face plate, and the working surface of the face plate is used to interact with the ground. When the face plate slides to the second position, the face plate is located on one side of the length direction of the base plate, and the working surface of the face plate is flush with the working surface of the base plate. At this time, the fastener is used to fix the face plate and the base plate together. The working surface of the face plate and the working surface of the base plate are used together to interact with the ground, and the dimension of the track plate along its length direction is increased, that is, the width dimension of the track is increased. This design allows for adjustment of the track width by sliding the panel, which is convenient and eliminates the need to completely separate the panel from the base plate or remove the panel for separate storage and transportation. This reduces costs and prevents accidental loss of the panel, solving the problems of high difficulty and cost in widening tracks in existing technologies.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0043] The following is combined with Figures 1 to 7 The track plate of the present invention is described.

[0044] like Figures 1 to 7 As shown, the track plate provided in this embodiment of the invention includes a base plate 1, a front panel 2, and fasteners.

[0045] Specifically, the thickness direction of the base plate 1 is consistent with the thickness direction of the track plates, referring to... Figure 1 The direction indicated by h. The length direction of the bottom plate 1 is consistent with the length direction of the track plate, refer to... Figure 1 In the direction indicated by m, when multiple track plates are connected to form a track, the length direction of the track plate is the width direction of the track. The width direction of the base plate 1 is consistent with the width direction of the track plates, and is perpendicular to the thickness direction and length direction of the base plate 1. (Refer to...) Figure 1 The direction indicated by n.

[0046] One of the two surfaces of the base plate 1 distributed along its own thickness direction is the working surface of the base plate 1, and the working surface of the base plate 1 is as follows: Figure 3 The surface indicated by P in the middle.

[0047] Panel 2 is slidably connected to base plate 1, and panel 2 can slide between a first position and a second position.

[0048] When panel 2 slides to the first position, panel 2 is located on the working surface side of base plate 1, and panel 2 overlaps with base plate 1. At this time, fasteners are used to fix panel 2 and base plate 1 together. The surface of panel 2 away from base plate 1 is the working surface of panel 2, and the working surface of panel 2 is as follows: Figure 7 The surface indicated by Q in the middle, the working surface of panel 2, is used to interact with the ground.

[0049] When panel 2 slides to the second position, panel 2 is located on one side of the base plate 1 along its length, and the working surface of panel 2 is flush with the working surface of base plate 1. At this time, fasteners are used to fix panel 2 and base plate 1 together. The working surface of panel 2 and the working surface of base plate 1 work together to interact with the ground, and the dimension of track plate along its length is increased, that is, the width dimension of track is increased.

[0050] This design allows for adjustment of the track width by sliding the panel 2, which is convenient and eliminates the need to completely separate the panel 2 from the base plate 1 when adjusting the track width. This reduces costs and prevents accidental loss of the panel 2, thus solving the problems of high difficulty and cost in widening tracks in existing technologies.

[0051] It should be noted that one base plate 1 can be provided with one panel 2, or one base plate 1 can be provided with two panels 2. The two panels 2 are distributed on both sides of the base plate 1 along its length. When one base plate 1 is provided with two panels 2, the track plate structure is symmetrical. When the track plate is applied to the track device, the base plate 1 is connected to the track link, the track plate is subjected to uniform force, and the track device has high stability.

[0052] It should be noted that the sliding connection structure between the two panels 2 and the base plate 1 is the same.

[0053] In this embodiment of the invention, a sliding groove is provided on the base plate 1, and a slider 5 is provided on the panel 2. The sliding connection between the panel 2 and the base plate 1 is realized through the cooperation of the slider 5 and the sliding groove.

[0054] Specifically, a horizontal slide groove 3 and a vertical slide groove 4 are provided on the base plate 1. The horizontal slide groove 3 extends along the length direction of the base plate 1, and the vertical slide groove 4 extends along the thickness direction of the base plate 1. The horizontal slide groove 3 is located on the side of the vertical slide groove 4 closest to the working surface of the base plate 1. The slider 5 can slide along the horizontal slide groove 3 or along the vertical slide groove 4.

[0055] The horizontal slide 3 is connected to the vertical slide 4, and the slider 5 can slide from the horizontal slide 3 to the vertical slide 4, or from the vertical slide 4 to the horizontal slide 3.

[0056] When slider 5 slides to the end of horizontal slide groove 3 away from vertical slide groove 4, the position of panel 2 is equivalent to the first position described above. When slider 5 slides to the end of vertical slide groove 4 away from horizontal slide groove 3, the position of panel 2 is equivalent to the second position described above.

[0057] In this embodiment, a limiting groove 6 is also provided on the base plate 1. The limiting groove 6 extends along the width direction of the base plate 1 and is located on the side of the vertical groove 4 away from the horizontal groove 3, and the limiting groove 6 is connected to the vertical groove 4. The slider 5 can also slide along the limiting groove 6. The slider 5 can slide from the vertical groove 4 to the limiting groove 6, and can also slide from the limiting groove 6 to the vertical groove 4.

[0058] When the panel 2 needs to be in the second position, the slider 5 needs to slide from the vertical slide groove 4 to the limiting slide groove 6. Through the interaction between the slider 5 and the side wall of the limiting slide groove 6, the slider 5 can be restricted to slide along the thickness direction of the base plate 1, thereby ensuring that the working surface of the base plate 1 and the working surface of the panel 2 remain flush, ensuring the positional stability of the panel 2 in the second position, and thus ensuring the stability of the track in a large width dimension.

[0059] It should be noted that when the base plate 1 is provided with a limiting groove 6, the position of the panel 2 can be regarded as equivalent to the second position mentioned above when the slider 5 is located at any position of the limiting groove 6.

[0060] The aforementioned horizontal slide groove 3 and vertical slide groove 4 are both located inside the base plate 1. The relative position of the slider 5 and the panel 2 is fixed. To ensure the smooth sliding of the panel 2 and the slider 5, the slider 5 can be located on the side of the panel 2 closer to the base plate 1 along the length direction of the base plate 1, and at the same time, the slider 5 can be located on the side of the panel 2 closer to the base plate 1 along the thickness direction of the base plate 1.

[0061] Reference Figure 7 The slider 5 can be set to a cylindrical shape, and the slider 5 is connected to the panel 2 through the connecting rod 12.

[0062] In this embodiment, along the thickness direction of the base plate 1, a first limiting part 7 is provided on the side of the transverse slide groove 3 away from the vertical slide groove 4. The first limiting part 7 can restrict the slider 5 from moving along the thickness direction of the base plate 1 in the transverse slide groove 3, thereby preventing the slider 5 from coming out of the transverse slide groove 3 along the thickness direction of the base plate 1.

[0063] Along the length of the base plate 1, a second limiting part 8 is provided on the side of the vertical slide groove 4 away from the horizontal slide groove 3. The second limiting part 8 can restrict the slider 5 from moving along the length of the base plate 1 in the vertical slide groove 4, thereby preventing the slider 5 from coming out of the vertical slide groove 4 along the length of the base plate 1.

[0064] In this embodiment, a first connecting hole 9 is provided on the base plate 1, and a second connecting hole 10 is provided on the panel 2. When the panel 2 is in the first position, the axis of the first connecting hole 9 coincides with the axis of the second connecting hole 10. At this time, a fastener is used to connect the first connecting hole 9 and the second connecting hole 10.

[0065] Reference Figure 3 and Figure 7 The axis of the first connecting hole 9 is set along the thickness direction of the base plate 1, and the axis of the second connecting hole 10 is parallel to the axis of the first connecting hole 9. Fasteners may include, but are not limited to, bolts.

[0066] At least one of the first connecting hole 9 and the second connecting hole 10 can be configured as a threaded hole, and the fastener can extend into the first connecting hole 9 and the second connecting hole 10, and the fastener is threadedly connected to the threaded hole.

[0067] A third connecting hole is provided on the base plate 1, and a fourth connecting hole is provided on the panel 2. When the panel 2 is in the second position, the axis of the third connecting hole coincides with the axis of the fourth connecting hole. At this time, fasteners are used to connect the third connecting hole and the fourth connecting hole.

[0068] The axis of the third connecting hole can be set along the length of the base plate 1, and the axis of the fourth connecting hole is parallel to the axis of the third connecting hole. Fasteners can be, but are not limited to, bolts.

[0069] At least one of the third and fourth connecting holes can be configured as a threaded hole, and the fastener can extend into the third and fourth connecting holes, and the fastener is threadedly connected to the threaded hole.

[0070] The fastener in this embodiment can be used to connect both the first connecting hole 9 and the second connecting hole 10, as well as the third connecting hole and the fourth connecting hole. It can be understood that the same fastener is used to connect the panel 2 and the base plate 1 in both the first and second positions. The fastener is always on the track plate in either state, eliminating the need for separate storage and preventing accidental loss.

[0071] In this embodiment of the invention, reinforcing ribs are provided on both the working surface side of the base plate 1 and the working surface side of the panel 2. Both the reinforcing ribs on the base plate 1 and the panel 2 extend along the length of the base plate 1. The plane containing the reinforcing ribs forms an angle with the working surface of the base plate 1 and the working surface of the panel 2.

[0072] Specifically, the plane of the reinforcing rib can be perpendicular to the working surface of the base plate 1, and the plane of the reinforcing rib can be perpendicular to the working surface of the panel 2.

[0073] The reinforcing ribs provide stronger support and protection for the base plate 1 and the panel 2, and the reinforcing ribs are used to contact the ground, increasing the friction between the base plate 1 and the ground, as well as the friction between the panel 2 and the ground.

[0074] A clearance groove is provided on the opposite side of the working surface of panel 2. That is, when panel 2 is in the first position, the clearance groove is located on the side of panel 2 closest to the base plate 1. The clearance groove is used to avoid the reinforcing ribs on the base plate 1, so as to avoid interference between the reinforcing ribs on the base plate 1 and panel 2, ensuring that panel 2 can slide smoothly relative to the base plate 1. Moreover, when panel 2 is in the first position, the surface of panel 2 closest to the base plate 1 can slide in contact with the working surface of the base plate 1, increasing the contact area between panel 2 and base plate 1, and improving the stability and reliability of the track plate.

[0075] In this embodiment of the invention, a handrail 11 is provided on the panel 2. When the panel 2 is in the second position, the handrail 11 is located on the side of the panel 2 away from the base plate 1. The handrail 11 facilitates the operator to apply force to the panel 2 and to adjust the position of the panel 2.

[0076] In this embodiment, a fifth connecting hole is provided on the base plate 1 for connecting with a track link, which is located on the opposite side of the working surface of the base plate 1. Connecting the base plate 1 to the track link does not affect the connection structure between the base plate 1 and the track link when adjusting the position of the panel 2. In other words, when adjusting the width of the track, only the position of the panel 2 needs to be adjusted, without operating other parts, making the operation simple.

[0077] In this embodiment, connecting portions are provided at both ends of the base plate 1 along its own width direction. The connecting portions are used to connect with the base plate 1 of the adjacent track plate to form a track.

[0078] Specifically, the connecting part is provided with a pin hole, which can be used to connect the bottom plates 1 of the two track plates together.

[0079] In summary, when the track plate provided in this embodiment of the invention is applied to the track, if it is necessary to increase the width of the track, the fasteners are removed from the first connecting hole 9 and the second connecting hole 10, force is applied to the panel 2 to slide the panel 2 to the second position, and then the fasteners are connected to the third connecting hole and the fourth connecting hole. The width of the track can be adjusted through this simple operation with high efficiency. Increasing the width of the track makes the tracked device more stable, increases the operating efficiency of the machinery, and allows the machinery to operate safely and efficiently in special working conditions such as muddy terrain and potholes.

[0080] If it is necessary to reduce the width of the track, remove the fasteners from the third and fourth connecting holes, apply force to the panel 2 to slide the panel 2 to the first position, and then connect the fasteners to the first and second connecting holes.

[0081] On the other hand, embodiments of the present invention also provide a track device, including the track plate provided in any of the above embodiments. When the track plate provided in any of the above embodiments is applied to a track device, the width of the track can be easily adjusted, and the cost is low. Therefore, the track device in this embodiment has the advantages of convenient track width adjustment and low cost. The derivation process of the beneficial effects of the track device in the embodiments of the present invention is largely similar to the derivation process of the beneficial effects of the track plate described above, and therefore will not be repeated here.

[0082] In another aspect, embodiments of the present invention also provide a working machine, including the track plates or track devices provided in any of the above embodiments. It possesses all the advantages of the aforementioned track plates or track devices, which will not be repeated here. The derivation process of the beneficial effects of the working machine in the embodiments of the present invention is largely similar to the derivation process of the beneficial effects of the aforementioned track plates or track devices, and therefore will not be repeated here.

[0083] In embodiments of the present invention, the type of working machinery is not limited; for example, the working machinery can be an excavator, crane, loader, etc. In other words, as long as the working machinery can use the track plates in the embodiments of the present invention, it is acceptable.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
