[0002] Since crawler walking devices have the characteristics of large traction, small ground contact pressure, small turning radius and large climbing ability, applying them to operating machinery can greatly enhance the environmental adaptability of the operating machinery, thereby ensuring the normal development of construction operations.

[0003] However, since the crawler tracks in the crawler-type walking device are usually metal structures, they may cause damage to the road, thereby affecting the service life of the road. Utility Model Content

[0004] In view of this, the utility model provides a track shoe assembly, a track and a track-type working machine to solve the problem that the track may cause damage to the road.

[0005] In a first aspect, the utility model provides a track shoe assembly, comprising:

[0006] A track shoe body, wherein a first plate surface of the track shoe body is provided with at least one groove extending along a first direction;

[0007] The protective cushion block comprises a cushion block body and at least one protrusion arranged on the first surface of the cushion block body, wherein the protrusion extends along a first direction and the protrusion corresponds to the groove one by one and is interference fit.

[0008] Beneficial effects: The utility model can increase the contact area between the track and the road and reduce the pressure applied to the road by arranging the protective pad in the groove of the track shoe body. In particular, when a crawler-type working machine is traveling on the track, the protective pad is arranged on the track shoe body to reduce the damage to the track. In addition, the protrusion and the groove are connected by an interference fit, which can ensure that the protective pad can be stably fixed on the track shoe body, reduce the number of parts used, and improve the convenience of installation and disassembly.

[0009] In an optional embodiment, the side wall of the groove is provided with a limiting protrusion and / or a limiting groove, and the protrusion is limitedly matched with the groove through the limiting protrusion and / or the limiting groove.

[0010] Beneficial effect: The utility model can effectively limit the movement range of the protective pad on the track shoe body by setting the limiting protrusion and / or limiting groove on the side wall of the groove, and increase the connection stability between the protrusion and the groove. In this way, it can prevent the protective pad from unnecessary displacement or falling off during the use of the track.

[0011] In an optional embodiment, along the direction away from the first surface, the size of the protrusion increases from small to large, and the shape of the protrusion matches the shape of the groove.

[0012] Beneficial effect: In the direction away from the first surface, the protrusion of the utility model is designed to gradually increase in size, which can increase the force exerted by the side wall of the groove on the protrusion, thereby improving the connection stability between the protrusion and the groove. In addition, since the size of the protrusion increases from small to large, the size of the notch of the groove will be smaller than the size of the groove bottom of the groove, so that the notch of the groove can have a certain limiting function, thereby preventing the protective pad from being displaced or falling off unnecessarily during the use of the crawler.

[0013] In an optional embodiment, an adhesive is provided between the protrusion and the groove.

[0014] Beneficial effect: The utility model can further improve the stability of the connection between the protrusion and the groove by setting an adhesive between the protrusion and the groove, especially for the case where the groove opening is large and there is no limiting structure.

[0015] In an optional embodiment, the pad block body is provided with extension portions on two opposite sides along a second direction, respectively, and the extension portions are used to overlap the top of the groove, wherein the second direction is perpendicular to the first direction.

[0016] Beneficial effect: The utility model overlaps the extension part on the top of the groove, so that the pad body is always located outside the groove. In this way, the track plate body is prevented from directly contacting the road, thereby reducing the probability of the track causing damage to the road during use.

[0017] In an optional embodiment, anti-slip patterns are provided on the second surface of the pad body.

[0018] Beneficial effect: The utility model can increase the friction between the protective pad and the road by arranging anti-skid patterns on the second surface of the pad body, thereby ensuring that the track has sufficient grip.

[0019] In an optional embodiment, the protection pad is a rubber pad, and the pad body and the protrusion are integrally formed.

[0020] Beneficial effect: The utility model sets the protective pad as a rubber pad, which has a certain elasticity. On the one hand, it can disperse the pressure exerted by the crawler on the road and reduce the damage to the road; on the other hand, it can absorb part of the vibration, reduce the noise generated by the crawler operation machine when driving, and improve the comfort of operation. In addition, the pad body and the protrusion adopt an integrated molding design, which can not only improve the overall strength of the protective pad, but also simplify the installation and replacement process and improve the efficiency of installation and removal.

[0021] In a second aspect, the utility model further provides a crawler, comprising:

[0022] A plurality of the above-mentioned track shoe assemblies, wherein the track shoe bodies are sequentially connected end to end to form the track, and the second surface of the pad body is used for contacting the ground.

[0023] Beneficial effects: The utility model combines a plurality of the above-mentioned track shoe assemblies into a track, which can, on the one hand, prevent the track shoe from causing damage to the road during use; on the other hand, it can reduce the possibility of damage to the track shoe body caused by the external environment.

[0024] In an optional embodiment, one of the protection pads is correspondingly mounted on at least one of the track shoe bodies.

[0025] Beneficial effect: When one protective pad corresponds to one track shoe body, subsequent maintenance and replacement operations can be more convenient and maintenance costs can be reduced. When one protective pad corresponds to multiple track shoe bodies, the number of parts in the installation process can be reduced, the operation steps can be simplified, and the installation efficiency can be improved.

[0026] In a third aspect, the utility model further provides a crawler type working machine, comprising:

[0027] Walking frame;

[0028] The above-mentioned crawler belts are respectively arranged around the opposite sides of the walking frame.

[0029] Beneficial effect: The utility model applies the above-mentioned crawler to a crawler-type working machine, which can reduce the pressure and damage caused by the crawler-type working machine to the road. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0039] In order to solve the problem that crawlers may cause damage to roads or other structures, the utility model provides a crawler shoe assembly, a crawler and a crawler type working machine.

[0040] Combine the following Figures 1 to 5 , describing an embodiment of the utility model.

[0041] According to an embodiment of the present utility model, on the one hand, as Figures 1 to 5 As shown, a track shoe assembly is provided, comprising: a track shoe body 1 and a protection pad 2.

[0042] Specifically, the first plate surface 101 of the track shoe body 1 is provided with at least one groove 1011 extending along the first direction; the protective pad 2 includes a pad body 201 and at least one protrusion 202 provided on the first surface 2011 of the pad body 201, the protrusion 202 extends along the first direction, and the protrusion 202 corresponds one-to-one with the groove 1011 and is interference fit.

[0043] The embodiment of the utility model can increase the contact area between the crawler 3 and the road and reduce the pressure applied to the road by arranging the protective pad 2 in the groove 1011 of the crawler body 1. In particular, when the crawler type working machine is running on the track, the protective pad is arranged on the crawler body to reduce the damage to the track. In addition, the protrusion 202 and the groove 1011 are connected by an interference fit, which can ensure that the protective pad 2 can be stably fixed on the crawler body 1, reduce the number of parts used, and improve the convenience of installation and disassembly.

[0044] It should be noted that the first plate surface 101 of the track shoe body 1 in this embodiment refers to the side for contacting the road, so the side opposite thereto is the second plate surface 102 for connecting with the driving wheel and other structures on the crawler machine. In addition, the first direction in this embodiment refers to the direction perpendicular to the traveling direction of the crawler machine, and the second direction refers to the direction consistent with the traveling direction of the crawler machine.

[0045] It should be noted that the first surface 2011 of the pad body 201 in this embodiment is a side surface of the pad body 201 facing the first plate surface 101 of the track shoe body 1. In addition, when the protective pad 2 needs to be installed on the groove 1011 on the track shoe body 1, there are at least two installation methods, and the installation methods of the protective pad 2 will be described below with reference to specific examples.

[0046] In one example, the first surface 2011 of the pad body 201 is set in the direction of the notch of the groove 1011, that is, the protrusion 202 on the first surface 2011 is aligned with the notch of the groove 1011, and then a force is applied on the pad body 201 to make the protrusion 202 enter the groove 1011 in the direction of the bottom of the groove 1011 until the top of the protrusion 202 abuts against the bottom of the groove 1011 or the protrusion 202 and the groove 1011 are stably connected together.

[0047] In another example, the groove 1011 is set to be full length, and both sides of the groove 1011 are connected to the track shoe body 1. During installation, the pad body 201 is set on one side of the track shoe body 1, and the protrusion 202 is pushed into the groove 1011 from the side opening of the groove 1011 along the first direction until the protrusion 202 completely enters the groove 1011 and is stably connected to the groove 1011.

[0048] According to an embodiment of the utility model, the side wall of the groove 1011 is provided with a limiting protrusion 1012 and / or a limiting groove 1013, and the protrusion 202 is limitedly matched with the groove 1011 through the limiting protrusion 1012 and / or the limiting groove 1013. The embodiment of the utility model can effectively limit the movement range of the protection pad 2 on the track shoe body 1 by providing the limiting protrusion 1012 and / or the limiting groove 1013 on the side wall of the groove 1011, and increase the connection stability between the protrusion 202 and the groove 1011. In this way, it can prevent the protection pad 2 from unnecessary displacement or falling off during the use of the track 3.

[0049] It is understandable that the present invention does not limit the specific setting form and position of the limiting protrusion 1012 and the limiting groove 1013 on the side wall of the groove 1011. As long as the protrusion 202 can be limited and cooperated with the groove 1011 through the limiting protrusion 1012 and / or the limiting groove 1013, the connection stability between the two can be further improved.

[0050] The following is an example of the arrangement of the limiting protrusion 1012 and the limiting groove 1013 on the side wall of the groove 1011:

[0051] Example 1:

[0052] The two side walls of the groove 1011 are respectively provided with limiting protrusions 1012 extending in the first direction, and the protrusion 202 is provided with a groove structure matched with the limiting protrusion 1012. During the installation of the protrusion 202, it is necessary to align the protrusion 202 with the position of the side opening of the groove 1011, and it is also necessary to align the groove structure with the position of the limiting protrusion 1012. Such an arrangement can ensure that the protrusion 202 and the groove 1011 will not fall off the track shoe body 1 under the limiting cooperation of the limiting protrusion 1012 and the groove structure.

[0053] Example 2:

[0054] A limiting groove 1013 extending in the first direction is provided on one side wall of the groove 1011, and a protrusion structure matched with the limiting groove 1013 is provided on the protrusion 202. During the installation of the protrusion 202, it is necessary to align the protrusion 202 with the position of the side opening of the groove 1011, and it is also necessary to align the position of the protrusion structure with the position of the limiting groove 1013. Such an arrangement can ensure that the protrusion 202 and the groove 1011 will not fall off from the track shoe body 1 under the limiting cooperation of the protrusion structure and the limiting groove 1013.

[0055] Example 3:

[0056] A limiting groove 1013 extending in the first direction is provided on one side wall of the groove 1011, a limiting protrusion 1012 extending in the first direction is provided on the other side wall of the groove 1011, and a groove structure adapted to the limiting protrusion 1012 and a protrusion structure adapted to the limiting groove 1013 are provided on the protrusion 202. During the installation process of the protrusion 202, it is necessary to align the protrusion 202 with the position of the side opening of the groove 1011, and it is also necessary to align the protrusion structure with the position of the limiting groove 1013, and the groove structure with the position of the limiting protrusion 1012. Such an arrangement can ensure that the protrusion 202 and the groove 1011 will not fall off from the track shoe body 1 under the limiting cooperation of the limiting protrusion 1012 and the groove structure, and the limiting groove 1013 and the protrusion structure.

[0057] Example 4:

[0058] From the notch of the groove 1011 to the bottom of the groove 1011, at least one limiting groove 1013 is arranged on the side wall of the groove 1011, and a protrusion structure matching the limiting groove 1013 is arranged on the protrusion 202. During the installation process of the protrusion 202, it is necessary to align the position of the protrusion 202 with the notch of the groove 1011, and it is also necessary to align the position of the protrusion structure with the limiting groove 1013. Such an arrangement can ensure that the protrusion 202 and the groove 1011 can be limited by the cooperation of the protrusion structure and the limiting groove 1013, and will not fall off the track shoe body 1.

[0059] According to an embodiment of the utility model, the size of the protrusion 202 increases from small to large in the direction away from the first surface 2011, and the shape of the protrusion 202 matches the shape of the groove 1011. In the direction away from the first surface, the protrusion in the embodiment of the utility model is designed to gradually increase, which can increase the force exerted by the side wall of the groove 1011 on the protrusion 202, thereby improving the connection stability between the protrusion 202 and the groove 1011. In addition, since the size of the protrusion increases from small to large, the size of the notch of the groove 1011 will be smaller than the size of the bottom of the groove 1011, so that the notch of the groove 1011 can have a certain limiting function, thereby preventing the protective pad 2 from being displaced or falling off during the use of the crawler 3. In this embodiment, the structure of the above-mentioned limiting protrusion 1012 and / or limiting groove 1013 on the side wall of the groove 1011 can be omitted.

[0060] According to an embodiment of the utility model, an adhesive is provided between the protrusion 202 and the groove 1011. The utility model embodiment can further improve the stability of the connection between the protrusion 202 and the groove 1011 by providing an adhesive between the protrusion 202 and the groove 1011, especially for the case where the opening of the groove 1011 is large and there is no limiting structure, providing an adhesive can increase the adhesion between the protrusion 202 and the groove 1011, and reduce the probability of the protective pad 2 falling off the track shoe body 1. It should be noted that the adhesive in this embodiment can be but is not limited to epoxy resin glue, polyurethane glue and acrylic glue, as long as the protrusion 202 and the groove 1011 can be firmly connected together, and the utility model does not make specific restrictions on this.

[0061] It can be understood that, whether the utility model sets a limiting structure on the side wall of the groove 1011, adjusts the shape of the groove 1011, or sets an adhesive between the protrusion 202 and the groove 1011, it can further improve the connection strength between the protrusion 202 and the groove 1011 on the basis of the interference fit connection between the protrusion 202 and the groove 1011, while maintaining the convenience of the installation operation.

[0062] According to an embodiment of the utility model, the pad body 201 is provided with extensions 2012 on opposite sides along the second direction, and the extensions 2012 are used to overlap the top of the groove 1011, wherein the second direction is perpendicular to the first direction. In the embodiment of the utility model, the extensions 2012 are overlapped on the top of the groove 1011, so that the pad body 201 is always located outside the groove 1011, so that the track shoe body 1 can be prevented from directly contacting the road, thereby reducing the probability of the track 3 causing damage to the road during use.

[0063] According to one embodiment of the utility model, Figure 3 As shown, the second surface 2013 of the pad body 201 is provided with anti-skid lines 2014. The embodiment of the utility model can increase the friction between the protective pad 2 and the road by providing the anti-skid lines 2014 on the second surface 2013 of the pad body 201, ensuring that the track shoe has sufficient grip.

[0064] It should be noted that the second surface 2013 of the pad body 201 is a side opposite to the first surface 2011, and is used to contact the road. In addition, the shape of the anti-slip pattern 2014 in this embodiment can be, but not limited to, stripe patterns, triangle patterns, star patterns, and flower patterns, as long as the friction between the protective pad 2 and the road can be increased, and the present invention does not make specific restrictions on this.

[0065] In a specific embodiment, the anti-slip pattern 2014 is in the shape of a stripe pattern on the second surface 2013 of the pad body 201. Compared with the anti-slip patterns 2014 of other shapes, the manufacturing process of the stripe pattern is relatively simple. Therefore, providing the stripe pattern on the second surface 2013 of the pad body 201 can reduce production costs and shorten production time.

[0066] According to an embodiment of the utility model, the protective pad 2 is a rubber pad, and the pad body 201 and the protrusion 202 are integrally formed. In the embodiment of the utility model, the protective pad 2 is set as a rubber pad, and the rubber pad has a certain elasticity. On the one hand, it can disperse the pressure applied by the crawler 3 on the road and reduce the damage to the road; on the other hand, it can absorb part of the vibration, reduce the noise generated by the crawler operating machinery during driving, and improve the comfort of operation. In addition, the pad body 201 and the protrusion 202 are designed to be integrally formed, which can not only improve the overall strength of the protective pad, but also simplify the installation and replacement process and improve the efficiency of installation and disassembly.

[0067] According to an embodiment of the utility model, on the other hand, a crawler 3 is provided, comprising: a plurality of the above-mentioned crawler shoe assemblies. Specifically, the crawler shoe bodies 1 are connected end to end in sequence to form the crawler 3, and the second surface 2013 of the pad body 201 is used to contact the ground. The embodiment of the utility model combines the plurality of the above-mentioned crawler shoe assemblies to form the crawler 3, which can prevent the crawler 3 from causing damage to the road during use, and can reduce the possibility of damage to the crawler shoe body 1 caused by the external environment.

[0068] According to an embodiment of the utility model, one protective pad 2 is correspondingly installed on at least one track shoe body 1. When one protective pad 2 corresponds to one track shoe body 1, subsequent maintenance and replacement operations are more convenient and maintenance costs are reduced. When one protective pad 2 corresponds to multiple track shoe bodies 1, the number of parts in the installation process can be reduced, the operation steps can be simplified, and the installation efficiency can be improved.

[0069] It should be noted that one protective pad 2 in this embodiment may correspond to two, three or six track shoe bodies 1. It is understandable that in order to ensure the convenience of installation and transportation, the number of protective pads 2 corresponding to the track shoe bodies 1 needs to be set within a reasonable range, which can be adjusted accordingly according to actual design needs and is not limited here.

[0070] According to an embodiment of the utility model, on the other hand, a crawler-type working machine is also provided, comprising: a traveling frame and the above-mentioned crawler 3. The crawler 3 is respectively arranged around the opposite sides of the traveling frame. The embodiment of the utility model applies the above-mentioned crawler 3 to the crawler-type working machine, which can reduce the pressure and damage caused by the crawler-type working machine to the road.

[0071] The crawler type working machine is taken as a track machine as an example to explain the crawler shoe assembly and the crawler 3 in the utility model:

[0072] Since the track machine needs to walk on the track, if the crawler 3 is directly in contact with the track, it will not only damage the crawler 3, but also damage the track's own structure. Therefore, a protective pad 2 is provided on the side where the crawler 3 contacts the ground, which can avoid direct contact between the crawler 3 and the track and increase the service life of the crawler 3 and the track. In addition, a protective pad 2 is provided on the side where the crawler 3 contacts the ground, which can increase the contact area between the crawler 3 and the track and increase the walking speed of the track machine on the track. Furthermore, an anti-skid pattern 2014 is provided on the second surface 2013 of the pad body 201, which can effectively increase the friction between the protective pad 2 and the track, improve the grip performance of the crawler 3, and improve the walking stability of the track machine on the track.
