[0002] Guide wheels are generally used in crawler-type walking mechanisms such as excavators, wherein the guide wheels are engaged with the tracks to guide the tracks and the entire chassis, thereby alleviating the impact of the tracks on the guide wheels during driving.

[0003] In an existing practical application, the guide wheel assembly is composed of a guide wheel, a guide wheel support, etc. The guide support limits the guide wheel in the left and right directions to prevent the guide wheel from detaching from the chain track of the crawler track.

[0025] Beneficial effects:

[0026] 1. The guide wheel assembly provided by the present invention comprises a guide seat and a guide wheel, a pair of slide grooves are arranged opposite to each other on both sides of the guide seat; the guide wheel can be rotatably arranged in the guide seat, a rotating shaft is arranged at the center of the guide wheel, and supports are respectively connected to the two ends of the rotating shaft, the supports are arranged in the slide grooves on the same side, and the supports are slidably connected with the slide grooves along a first direction.

[0038] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In the description of the embodiments of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limitations on the embodiments of the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0040] like Figure 5As shown, a guide wheel assembly of the prior art is composed of a guide wheel 1, a guide seat 2, etc. Slide grooves 3 are arranged on both sides of the guide seat 2, which can limit the guide wheel 1 in the left and right directions to prevent the guide wheel 1 from detaching from the chain track of the track. However, when turning, the guide seat 2 will be subjected to a large axial force, and the axial force is transmitted to the guide seat 2 through the support 4 of the guide wheel 1. During long-term use, the guide seat 2 will be opened and deformed, and the position of the track will swing violently left and right with the guide wheel 1. The coordination between the wheel system of the entire chassis and the track will fail, causing the track to derail and jump teeth.

[0041] Combine the following Figures 1 to 4 A guide wheel assembly, a traveling mechanism and a working machine provided by an embodiment of the present invention are described.

[0042] This embodiment provides a guide wheel assembly, such as Figures 1 to 3 As shown, it includes: a guide seat 2 and a guide wheel 1.

[0043] A pair of slide grooves 3 are arranged on both sides of the guide seat 2, and the slide grooves 3 extend along a first direction. The first direction can be a vertical direction, a horizontal direction, or other directions. Figure 1 In the illustrated embodiment, the first direction is a horizontal direction, that is, a pair of slide grooves 3 are horizontally arranged on both sides of the guide seat 2 .

[0044] The guide wheel 1 is rotatably arranged in the guide seat 2, and a rotating shaft is arranged at the center of the guide wheel 1. The guide wheel 1 is connected to the rotating shaft through a bearing to realize the rotation of the guide wheel 1 around the rotating shaft; the two ends of the rotating shaft are respectively connected to the support 4, each support 4 is arranged in the slide groove 3 on the same side, and the support 4 is slidably connected with the slide groove 3 along the first direction, that is, the support 4 can slide in the slide groove 3 along the length direction of the slide groove 3.

[0045] A limiting groove 5 is provided on the sliding connection surface of one of the support 4 and the slide groove 3, and a limiting protrusion 6 is provided on the sliding connection surface of the other one. The limiting groove 5 and the limiting protrusion 6 extend along the first direction, and the limiting protrusion 6 slides with the limiting groove 5 to limit the movement of the support 4 along the axial direction. When the guide wheel 1 is deflected by the axial force, the support 4 can be deflected synchronously with the slide groove 3 so that the support 4 will not detach from the slide groove 3.

[0046] It can be seen from the above scheme that, compared with the prior art, the present invention arranges the two supports 4 of the guide wheel 1 in the slide groove 3, and the support 4 can slide and cooperate with the slide groove 3 in the horizontal direction, so that the guide wheel 1 can move in the guide seat 2, which can alleviate the impact and vibration of the track on the guide wheel 1 during driving; by setting the limiting groove 5 and the limiting protrusion 6 between the slide groove 3 and the support 4, the straightness and stability of the relative sliding of the support 4 and the slide groove 3 can be ensured, and the movement of the support 4 along the axial direction can be limited. In this way, when the steering guide wheel 1 is subjected to axial force, the structures on both sides of the guide seat 2 can be connected together, thereby avoiding the opening deformation caused by the axial force on one side of the guide seat 2, which leads to the failure of the axial limit of the guide seat 2 on the guide wheel 1.

[0047] In this embodiment, if Figure 2 As shown, the limiting groove 5 is arranged on the upper and lower surfaces of the support 4, and a pair of limiting protrusions 6 are arranged on the upper and lower surfaces of the slide groove 3 along the length direction of the slide groove 3, and the limiting protrusions 6 are slidably matched with the limiting groove 5.

[0048] In this way, limiting grooves 5 are respectively provided on the upper and lower surfaces of the support 4, and limiting protrusions 6 are respectively provided on the upper and lower surfaces in the slide groove 3. The limiting protrusions 6 are inserted into the limiting grooves 5, and the two are slidably connected, which can limit the movement of the support 4 along the axial direction and will not interfere with the movement of the guide wheel 1 in the guide seat 2; because the upper and lower surfaces of the support 4 are concave and convex with the slide groove 3, the support 4 can be prevented from being separated from the slide groove 3 when the guide wheel 1 is deflected. When the guide wheel 1 is subjected to axial force, through this structure, the support 4 can be connected with the structures on both sides of the guide seat 2, thereby avoiding the situation where the axial limit of the guide seat 2 on the guide wheel 1 fails.

[0049] Furthermore, since the upper and lower surfaces of the slide groove 3 are respectively provided with limiting protrusions 6, and during the operation of the operating machine, impurities such as mud, sand and gravel particles may exist between the limiting groove 5 and the limiting protrusion 6, in order not to affect the relative sliding of the two, the limiting protrusion 6 is provided with multiple mud discharge grooves 7 at intervals along its length direction. The shape and structure of the mud discharge groove 7 should be conducive to the discharge of mud particles, such as a V-shape. Multiple mud discharge holes 8 are provided on one side or both sides of the limiting protrusion 6. The mud discharge holes 8 correspond to the position of the mud discharge groove 7, so as to facilitate the discharge of mud, sand and gravel particles between the limiting groove 5 and the limiting protrusion 6, and they will not accumulate at the bottom of the mud discharge groove 7.

[0050] In some other embodiments, a pair of limiting protrusions 6 are arranged on the upper and lower surfaces of the support 4, and a pair of limiting grooves 5 are arranged on the upper and lower surfaces of each slide groove 3 along the length direction of the slide groove 3. At this time, the limiting protrusion 6 is provided with a plurality of mud discharge grooves 7 at intervals along its length direction, and the limiting groove 5 is provided with a plurality of mud discharge holes at intervals along its length direction, and the mud discharge holes correspond to the mud discharge groove 7 up and down, so that the mud and sand and gravel particles between the limiting groove 5 and the limiting protrusion 6 can be directly discharged through the mud discharge holes in the limiting groove 5.

[0051] The above-mentioned support 4 can adopt a block structure, including but not limited to a rectangular block, which can provide flat upper and lower surfaces, which is conducive to the sliding fit between the support 4 and the slide groove 3, and the upper and lower surfaces of the support 4 are both flat, which is convenient for setting the limit groove 5 or the limit protrusion 6.

[0052] In some other embodiments, a limiting groove 5 and a limiting protrusion 6 may be respectively provided on the upper and lower surfaces of the support 4, and a limiting protrusion 6 and a limiting groove 5 may be respectively provided on the upper and lower surfaces of the slide groove 3 correspondingly, so as to achieve an axial limiting effect on the support 4 and prevent the support 4 from detaching from the slide groove 3 along the axial direction.

[0053] Of course, this is just an example and is not intended to limit the scope of protection.

[0054] Reference Figure 3 In this embodiment, the guide seat 2 includes a pair of side plates 21 arranged at intervals, a space for accommodating the guide wheel 1 is formed between the pair of side plates 21, and a pair of the above-mentioned slide grooves 3 are correspondingly arranged on the inner surfaces of the pair of side plates 21.

[0055] In a specific embodiment, the slide 3 includes a first connecting plate 31 and a second connecting plate 32, the first connecting plate 31 is connected to the inner side of the side plate 21 along the first direction, the second connecting plate 32 is connected to the inner side of the side plate 21 along the first direction, the first connecting plate 31 and the second connecting plate 32 are spaced apart along the second direction on the inner side of the side plate 21, and the second direction can be a vertical direction, a horizontal direction, or other directions. Figure 1 In the illustrated embodiment, the second direction is perpendicular to the first direction and is a vertical direction.

[0056] Optionally, the first connecting plate 31 and the second connecting plate 32 may be integrally formed with the main body of the guide seat 2 , welded, or connected via fasteners.

[0057] Preferably, the first connecting plate 31 and the second connecting plate 32 are of the same size, and both the first connecting plate 31 and the second connecting plate 32 are connected to the guide seat 2 through a supporting connection structure, so as to improve the stress stability of the first connecting plate 31 and the second connecting plate 32; Figure 3 As shown, the supporting connection structure can be a supporting plate or a supporting block.

[0058] In this embodiment, a pair of limiting protrusions 6 are respectively arranged on the inner surfaces corresponding to the first connecting plate 31 and the second connecting plate 32. The limiting protrusions 6 are provided with mud discharge grooves 7 at intervals along the length direction thereof. Figure 4 In the embodiment shown, the mud discharge groove 7 can be a V-shaped groove. The inclined surface of the V-shaped groove can facilitate the discharge of mud and sand particles between the limiting groove 5 and the limiting protrusion 6, and they will not accumulate at the bottom of the mud discharge groove 7; in other embodiments, the two inclined surfaces of the mud discharge groove 7 can be set as concave arc surfaces, which is also conducive to the discharge of mud.

[0059] With such arrangement, due to different working environments, impurities such as mud, sand and gravel particles may exist between the limiting groove 5 and the limiting protrusion 6. In order not to affect the relative sliding of the support 4 and the slide trough 3, a mud discharge groove 7 is arranged on the limiting protrusion 6 at intervals. There is a space between the mud discharge groove 7 and the limiting groove 5 on the support 4. As the guide wheel of the operating machine is impacted or vibrated during the driving process, the mud, sand and gravel particles can be discharged easily through the mud discharge groove 7 during the movement along the slide trough 3.

[0060] The above is only an example and is not intended to limit the protection scope. The shape of the mud trough 7 is not limited to the above form. Other mud trough 7 structures that are conducive to discharging mud and will not accumulate in the mud trough 7 are within the protection scope of the present invention.

[0061] Furthermore, a mud discharge hole 8 is provided at a position corresponding to the mud discharge groove 7 on the first connecting plate 31, and the mud discharge hole 8 is provided on one side or both sides of the limiting protrusion 6, and the bottom of the mud discharge groove 7 is higher than the upper surface of the second connecting plate 32, or is flush with the upper surface of the second connecting plate 32, so that the mud and sand can fall smoothly into the mud discharge hole 8; the shape of the mud discharge hole 8 can be rectangular, circular, polygonal or other irregular shapes, and is used to guide the mud and sand discharged through the mud discharge groove 7 to the outside of the chute 3 through the mud discharge hole 8.

[0062] With such arrangement, the mud particles discharged from the mud discharge groove 7 are discharged from the guide seat 2 through the mud discharge hole 8, which effectively ensures the free sliding of the guide wheel 1 in the front-rear direction on the guide seat 2, and avoids the occurrence of the guide wheel 1 being stuck due to mud, sand and gravel.

[0063] In other embodiments, a pair of limiting grooves 5 are respectively arranged on the inner surfaces corresponding to the first connecting plate 31 and the second connecting plate 32 (not shown in the figure), and the limiting protrusions 6 are arranged on the upper and lower surfaces of the support 4, and the limiting protrusions 6 are slidably matched with the limiting grooves 5. In other words, the same concave-convex matching method is adopted, but the protrusions are arranged on the upper and lower surfaces of the support 4, and the limiting grooves 5 are arranged on the upper and lower surfaces of the slide 3. In this way, by inserting the limiting protrusions 6 on the support 4 into the limiting grooves 5 in the slide 3, the two can also achieve sliding connection, and the situation where the axial limiting failure of the guide seat 2 on the guide wheel 1 can also be avoided.

[0064] Furthermore, in this embodiment, the limiting protrusion 6 is provided with mud discharge grooves 7 at intervals along its length direction, and the limiting groove 5 is provided with mud discharge through holes at intervals along its length direction. Since the limiting protrusion 6 is provided on the upper and lower surfaces of the support 4, and the limiting groove 5 is provided on the inner surfaces of the first connecting plate 31 and the second connecting plate 32, the limiting groove 5 on the first connecting plate 31 is prone to accumulate mud and gravel. By providing the mud discharge grooves 7 at intervals on the limiting protrusion 6 and correspondingly providing the mud discharge through holes at intervals on the limiting groove 5, mud and gravel can be directly discharged from the limiting groove 5, and the mud discharge effect is also achieved.

[0065] Reference Figure 1 , Figure 2 In this embodiment, a plurality of tooth structures 9 are evenly arranged on the circumferential surface of the guide wheel 1. Specifically, the teeth are arranged on the limiting flange in the middle of the outer circumferential surface of the guide wheel 1, and the limiting flange is used to cooperate with the crawler to prevent the guide wheel 1 from being separated from the crawler; by arranging the tooth structure 9 on the limiting flange of the guide wheel 1, the guide wheel 1 can scrape or crush the soil when it is engaged with the crawler track, avoiding the compaction of the soil inside the track, which causes the guide wheel 1 to derail.

[0066] An embodiment of the present invention provides a walking mechanism, comprising: a crawler track, a driving wheel and the above-mentioned guide wheel assembly.

[0067] The crawler track is composed of a plurality of crawler plates which are connected in sequence to form a closed loop. The driving wheel is arranged in the crawler track and is located at the rear end of the crawler track. The guide wheel 1 is arranged in the crawler track and is located at the front end of the crawler track.

[0068] The walking mechanism with the above-mentioned guide wheel 1 can achieve the guiding function and limit the movement of the support 4 along the axial direction to separate from the slide groove 3 through the concave-convex plug-in fit between the support 4 of the guide wheel 1 and the slide groove 3 of the guide seat 2 when working. At the same time, it also plays the role of connecting the support 4 with the structures on both sides of the guide seat 2, so that the guide seat 2 is no longer subjected to unilateral force when subjected to axial deflection force, effectively avoiding the occurrence of the opening deformation of the guide seat 2 caused by the axial force.

[0069] The mud discharge groove 7 and mud discharge hole 8 provided in the chute 3 can effectively discharge the mud and gravel in the support 4 and the chute 3, effectively ensuring that the guide wheel 1 slides freely on the guide seat 2, and avoiding the jamming of the guide wheel 1 caused by mud and gravel. The toothed structure 9 on the guide wheel 1 can effectively scrape and crush the mud inside the crawler chain track, which is conducive to the discharge of the mud on the crawler chain track, and can effectively avoid the derailment of the guide wheel 1 caused by mud accumulation.

[0070] In addition, the traveling mechanism also includes a tensioning device, a plurality of supporting rollers and a plurality of sprocket wheels. The tensioning device is arranged in the crawler and connected to the bracket, and is used to buffer the guide wheel 1. The plurality of supporting rollers are arranged in the crawler at intervals and are located below the driving wheel and the guide wheel 1. The plurality of sprocket wheels are arranged in the crawler at intervals and are located above the driving wheel and the guide wheel 1.

[0071] The embodiment of the present invention further provides a working machine, comprising the above-mentioned traveling mechanism. The above-mentioned working machine is a crawler-type working machine, such as an excavator, a crane, and the like.
