Description

Technical Field

[0001] The utility model relates to the technical field of loaders, in particular to a cut-resistant solid tire for loaders. Background Art

[0002] A loader is a type of earthwork machinery widely used in construction projects such as roads, railways, buildings, hydropower, ports, and mines. It is mainly used to shovel bulk materials such as soil, sand, lime, and coal. It can also perform light shoveling operations on ore, hard soil, etc. By replacing different auxiliary working devices, it can also perform bulldozing, lifting, and loading and unloading of other materials such as wood.

[0003] Since loaders work in special working conditions, some loaders are usually equipped with solid tires for wear resistance and puncture resistance during operation.

[0004] For example, Chinese patent CN 214606932 U discloses a cut-resistant solid tire for a telescopic forklift, comprising a rubber tire and an anti-skid pattern arranged on the outer wall of the rubber tire, the inner cavity of the rubber tire is sleeved with a reinforced steel ring, and the outer wall of the reinforced steel ring is evenly fixedly connected with a limit strip, and the inner wall of the rubber tire at the end of the limit strip is provided with a limit groove, and the inner cavity of the limit groove is respectively embedded with an elastic ball, and the tire is designed to have a double-layer structure with a solid inner tube and a solid outer tube, and a metal ring sheet is arranged on the outer wall of the solid outer tube, and convex columns are evenly arranged on the outer wall of the metal ring sheet, and a metal mesh is penetrated through the outer wall of the convex column, and the metal mesh is arranged in contact with the outer wall of the metal ring sheet, and a fireproof layer is arranged in contact with the outer wall of the metal mesh, and the metal ring sheet is penetrated and connected to the metal mesh through the convex column. When the tire is cut by a sharp object, it is first intercepted by the metal mesh, and then isolated and resisted by the convex column and the metal ring sheet, which effectively prevents the sharp object from continuing to pierce the tire, and fully guarantees the safety of the tire.

[0005] In actual application, although the above-mentioned cut-resistant tires ensure the anti-puncture function during operation, due to the deep diameter of the heat dissipation holes thereon and the fact that the solid tire will accumulate a lot of heat during long-term operation, it is difficult to dissipate the heat inside the solid tire only through the natural heat dissipation of the heat dissipation holes. The solid tire that cannot dissipate the temperature in time will accelerate the aging and cracking of its own rubber, which is likely to affect its designed service life. Therefore, a cut-resistant solid tire for a loader is proposed. Utility Model Content

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a cut-resistant solid tire for a loader with an effective heat dissipation structure.

[0007] A cut-resistant solid tire for a loader according to an embodiment of the utility model comprises:

[0008] The reinforcing steel ring has limiting side rings on both side edges, and an embedding groove is formed between the two limiting side rings;

[0009] A solid main carcass is assembled on the reinforcing steel ring by inserting a groove, and heat dissipation grooves are provided on both sides of the solid main carcass;

[0010] A solid auxiliary carcass, which has two parts, wherein the two solid auxiliary carcasses are respectively fixed on both sides of the solid main carcass and assembled in the embedding groove;

[0011] An annular spoiler groove is provided inside the solid secondary carcass, and a negative pressure cylinder is provided at a position inside the annular spoiler groove corresponding to the heat dissipation groove. The solid secondary carcass is subjected to pressure to cause the negative pressure cylinder to deform, so as to promote air flow inside the heat dissipation groove.

[0012] The cut-resistant solid tire for loaders according to the embodiment of the utility model has at least the following beneficial effects: through the mutual arrangement of the solid main carcass and the solid auxiliary carcass, when the loader is working, the solid main carcass ensures the stability of the working support while the deformable solid auxiliary carcass promotes the extrusion of the negative pressure cylinder, and because the carcass is in continuous rotation, the negative pressure cylinder that is continuously squeezed and released will promote the flow of air inside it, and because the negative pressure cylinder is connected to the corresponding heat dissipation groove, the flow of air inside the heat dissipation groove is also promoted to further improve its heat dissipation effect. Compared with traditional passive heat dissipation, the solid tire achieves active heat dissipation through reciprocating extrusion to reduce the temperature of the solid tire during operation, and avoids the internal temperature failing to dissipate in time, and the operation remains in a high temperature state for a long time, affecting its own service life.

[0013] According to an embodiment of the utility model, an assembly groove is provided at the edge of one side of the solid secondary carcass, and the reinforcing steel ring is engaged and assembled with the assembly groove through a limiting side ring.

[0014] According to an embodiment of the utility model, a fastening bolt is threadedly assembled on the surface of the limiting side ring, and one end of the fastening bolt penetrates through the thread of the limiting side ring and is inserted into the solid secondary tire body to form a connection and fastening.

[0015] According to an embodiment of the utility model, a rubber support is provided between the two negative pressure cylinders, and the annular spoiler groove is annular in shape under the action of the rubber support when there is no external force.

[0017] According to an embodiment of the utility model, the cut-resistant layer includes a fireproof layer, a metal mesh layer and a metal ring sheet layer;

[0018] The metal ring sheet layer, the metal mesh layer and the fireproof layer are sequentially sleeved on the surface of the carcass layer from the inside to the outside to form the solid main carcass.

[0019] According to an embodiment of the utility model, a negative pressure space is provided in the negative pressure cylinder, and the negative pressure space is communicated with the corresponding heat dissipation groove.

[0020] According to an embodiment of the utility model, an embedded chamfer is formed at the connection between the negative pressure cylinder and the heat dissipation groove.

[0021] According to an embodiment of the utility model, the surface of the fireproof layer is provided with wear-resistant rubber bumps, and there are multiple wear-resistant rubber bumps which are staggeredly distributed on the surface of the fireproof layer.

[0022] According to an embodiment of the utility model, the surface of the reinforcing steel ring is provided with an assembly hole for assembly with an external vehicle-mounted connector.

[0042] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0044] In the description of the utility model, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0045] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0046] As described in the background technology, although the current cut-resistant tires ensure the anti-puncture function during operation in actual applications, due to the deep diameter of the heat dissipation holes thereon and the fact that the solid tires will accumulate a lot of heat during long-term operation, it is difficult to dissipate the heat inside the solid tire only through the natural heat dissipation of the heat dissipation holes. Solid tires that cannot dissipate the temperature in time will accelerate their own rubber aging and cracking problems, which is likely to affect their own designed service life.

[0047] To this end, the utility model proposes a cut-resistant solid tire for a loader, specifically referring to the attached drawings of the specification. Figure 1-Figure 9 shown.

[0048] Example 1

[0049] Reference Figure 1-Figure 9 As shown, a cut-resistant solid tire for a loader according to an embodiment of the utility model comprises a reinforcing steel ring 1, both edges of which are provided with limiting side rings 11, and an embedding groove 12 is formed between the two limiting side rings 11; a solid main carcass 2, which is assembled by being sleeved on the reinforcing steel ring 1 through the embedding groove 12, and both sides of the solid main carcass 2 are provided with heat dissipation grooves 21; a solid auxiliary carcass 3, which has two, and the two solid auxiliary carcasses 3 are respectively fixed on both sides of the solid main carcass 2 and assembled in the embedding groove 12; an annular spoiler groove 31 is provided inside the solid auxiliary carcass 3, and a negative pressure cylinder 32 is provided at a position in the annular spoiler groove 31 corresponding to the heat dissipation groove 21, and the negative pressure cylinder 32 is deformed by the pressure on the solid auxiliary carcass 3 to promote the air flow inside the heat dissipation groove 21;

[0050] like Fig. 9 As shown, when the solid tire is actually applied to a loader, a stable support can be formed by the solid main carcass 2 to meet the stable movement of the loader during operation, and the solid auxiliary carcasses 3 are arranged on both sides of the solid main carcass 2, so that when the solid tire rolls, the solid auxiliary carcass 3 at the edge will be squeezed by the ground objects and deformed, and the annular spoiler groove 31 and the negative pressure cylinder 32 in the solid auxiliary carcass 3 in the deformed state will both be deformed, and the negative pressure cylinder 32 will be continuously squeezed and released during the continuous rolling of the solid tire, and in the process of squeezing, the negative pressure cylinder 32 can be squeezed back and forth, thereby promoting the air flow inside it, and effectively taking away the heat in the heat dissipation groove 21 on the solid tire by promoting the air flow, so as to stabilize the temperature of the solid tire when the loader is operating;

[0051] Example 2

[0052] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, based on Example 1, the cut-resistant solid tire for a loader is further optimized, an assembly groove 33 is provided at the edge of one side of the solid secondary carcass 3, the reinforcing steel ring 1 is engaged with the assembly groove 33 through the limiting side ring 11, and a fastening bolt 110 is threadedly assembled on the surface of the limiting side ring 11, and one end of the fastening bolt 110 passes through the limiting side ring 11 and is threadedly arranged in the solid secondary carcass 3 to form a connection and fastening;

[0053] By setting the above-mentioned assembly groove 33, when the solid auxiliary carcass 3 is embedded and installed in the embedding groove 12, the solid auxiliary carcass 3 is limited by the limiting side ring 11, thereby ensuring the stability of the relative position of the solid auxiliary carcass 3 and the solid main carcass 2 thereon with respect to the reinforcing steel ring 1 after assembly;

[0054] At the same time, by tightening the bolts 110, the connection between the reinforcing steel ring 1 and the solid secondary carcass 3 can be completed, ensuring that when the reinforcing steel ring 1 is driven to rotate by the loader, the solid secondary carcass 3 and the solid main carcass 2 will not slide relative to each other;

[0055] The number of the above-mentioned fastening bolts 110 can be reasonably set according to the actual assembly situation, and only needs to ensure the stability of the tire body when the loader is in use;

[0056] The surface of the reinforcing steel ring 1 is provided with an assembly hole 13 for assembly with an external vehicle-mounted connecting piece. In actual application, the assembly hole 13 is used to complete the connection and assembly between the solid tire and the external loader.

[0057] Example 3

[0058] like Fig. 9 As shown, the cut-resistant solid tire for loaders is further optimized on the basis of Example 2: the solid main carcass 2 includes a carcass layer 22 sleeved on the surface of the reinforcing steel ring 1 and a cut-resistant layer 23 sleeved on the surface of the carcass layer 22;

[0059] The cut-resistant layer 23 includes a fireproof layer 230, a metal mesh layer 231 and a metal ring sheet layer 232. The metal ring sheet layer 232, the metal mesh layer 231 and the fireproof layer 230 are sequentially sleeved on the surface of the carcass layer 22 from the inside to the outside to form a solid main carcass 2.

[0060] The cut-resistant layer 23 in the solid main carcass 2 can refer to a cut-resistant solid tire for a telescopic forklift disclosed in Chinese patent CN 214606932 U. When the tire is cut by a sharp object, the cut-resistant layer 23 is first intercepted by the metal mesh layer 231, and then isolated and resisted by the metal ring layer 232, which effectively prevents the sharp object from further piercing the tire, fully ensuring the safety of the tire and meeting the operation requirements of the loader under special working conditions.

[0061] As a further optimization of this embodiment: in actual application, the outer side of the solid sub-carcass 3 may also be provided with a cut-resistant layer 23, but since the solid sub-carcass 3 in this application does not bear the main load-bearing function of the loader, and when the solid sub-carcass 3 is subjected to pressure, it will also avoid it by deformation to avoid rigid contact, so it is not necessary to set it in this embodiment;

[0062] like Figure 1 As shown, as a further optimization of this embodiment: the surface of the fireproof layer 230 is provided with wear-resistant rubber protrusions 233, and there are multiple wear-resistant rubber protrusions 233 distributed in an alternating manner on the surface of the fireproof layer 230. Through the arrangement of multiple wear-resistant rubber protrusions 233, the grip of the contact surface between the carcass and the ground is improved, thereby meeting the stability during use.

[0063] Example 4

[0064] like Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the cut-resistant solid tire for a loader is further optimized on the basis of Example 3, a negative pressure space 320 is provided in the negative pressure cylinder 32, the negative pressure space 320 is connected to the corresponding heat dissipation groove 21, and an insert chamfer 321 is formed at the connection between the negative pressure cylinder 32 and the heat dissipation groove 21;

[0065] When the solid tire is used on a loader, the solid secondary carcass 3 that is continuously reciprocated and released will cause the negative pressure cylinder 32 inside to be deformed and reset synchronously, so that the negative pressure space 320 will repeatedly exhaust and inhale to promote the air flow inside it. Since the negative pressure space 320 and the heat dissipation groove 21 are interconnected, the negative pressure space 320 will also synchronously promote the air flow in the heat dissipation groove 21 when inhaling or exhausting air, so as to take away the air with a higher temperature in the heat dissipation groove 21, thereby realizing the internal cooling of the solid main carcass 2 and ensuring the structural stability of the tire.

[0066] As a further optimization of this embodiment: a rubber support 34 is provided between the two negative pressure cylinders 32, and the annular spoiler groove 31 is annular in the absence of external force due to the action of the rubber support 34;

[0067] The cooperation of the plurality of rubber supports 34 can improve the deformation degree of the solid secondary carcass 3 when under pressure, and can also assist the solid secondary carcass 3 to rebound after deformation. In practice, the number of rubber supports 34 can be adjusted to control the deformation pressure and reset speed of the solid secondary carcass 3.

[0068] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings. Finally, it should be explained that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
