Description

FIELD OF TECHNOLOGY

The present invention relates to a liner for a mining truck body and a transitional liner for use in a mining truck body. In addition, the invention relates to a method for attaching a lining to a dump truck body.

BACKGROUND OF THE INVENTION

Mining trucks are rough terrain dump trucks designed for use in heavy duty mining and construction operations. Mining trucks are equipped with bodies capable of carrying a large amount of material, such as rock, crushed ore, or similar material. The capacity of mining trucks ranges from 40 short tons (36 t) to 496 short tons (450 t). Transportation of such loads, often with sharp edges and having a large mass, leads to the fact that the body of a mining truck experiences severe wear as a result of impact and abrasion.

To protect the surface of the body of a mining truck, the inside of its body is usually equipped with a lining. Although the body of a mining truck is usually made of steel, the lining is often made of a different material. One commonly used type of lining is a flexible lining containing, for example, a rubber material or polyurethane. The advantage of a flexible lining material is that the properties of this material can be used to mitigate the strong impact of the loaded material on the body of a mining truck when this material is moved from a considerable height into the specified body, for example, from an excavator. The elastic lining material effectively absorbs impact energy, distributing it over a larger area. In addition, noise is reduced and a more comfortable environment for the operator is created. The lining for mining trucks is usually made of lining elements that pass over the surfaces of the body of a mining truck to form a lining. A separate lining element simplifies manufacturing by limiting the size and weight of said element. In addition, mining truck body maintenance is facilitated because individual damaged or worn liners can be replaced on site without the need to remove large portions of the surrounding lining.

A problem with such a liner for a mining truck body is that the loading material can penetrate downward through openings between adjacent liner elements. As a result, the material can cause further damage to the lining as it wears out the fasteners. In addition, the stuck material increases the re-transported load, i.e. the amount of material that cannot leave the body of a mining truck during long-term operation. Retransported cargo is undesirable because it does not allow the equipment to operate at full capacity, and if part of the equipment is directly related to production, the maximum possible output is violated. Secondary effects caused by the presence of re-transported cargo include higher maintenance costs due to faster material wear and additional downtime required to clean equipment.

SUMMARY OF THE INVENTION

In view of the foregoing, it is an object of the present invention to limit, reduce the impact or eliminate one or more of the above disadvantages of the prior art, as well as individual disadvantages or any combination thereof, and to solve at least the aforementioned problem.

According to the first aspect, a lining for a mining truck body is proposed, containing main lining elements passing over the main surfaces of the specified body, and transition lining elements passing over the edge and/or corner sections of the specified body, each transition lining element forming a transition section of the lining between non-parallel main lining elements from said main lining elements, wherein said transition lining elements comprise at least one non-linear transition lining element that has first and second flanges extending in respective non-parallel directions, wherein the first flange forms a first transition section of the lining between the first pair of non-parallel main lining elements, and the second shelf forms the second transition section of the lining between the second pair of non-parallel main lining elements, and three of the main lining elements of these the first and second pairs of main lining elements are not parallel to each other.

In other words, a lining for a mining truck body is proposed, containing main lining elements passing over the main surfaces of the specified body, and transitional lining elements passing over the edge and/or corner sections of the mining truck body, with each transitional lining element forming a transition lining section between at least two non-parallel main liners of said main liners, and the transition liners comprise at least one non-linear transition liner that has first and second flanges extending in non-parallel respective directions.

The proposed lining provides at least the following advantages:

- If a transitional lining element is located in the corner or along the wedge-shaped sections of the body of a mining truck, this element can prevent or at least significantly reduce the formation of a gap in the lining located in close proximity to the corner or wedge-shaped section. As a result, the risk of penetration of material inside the body of a mining truck through the specified gap and into the space available under the lining elements and causing an increased risk of damage to the lining and an increase in re-transported cargo can be reduced.

- The non-linear transition liner can be designed to fit into the corner or wedge of a particular mining truck body. Thus, the use of this transition liner simplifies the installation of the liner in the back of a mining truck, since one element can replace two or more separate conventional liner elements.

- The use of transition lining elements makes it possible to form a uniform transition section of the lining between the main lining elements having different thicknesses. For example, transition linings can be used to form a smooth transition between a 15 cm thick lining located on the bottom of a mining truck body and a 10 cm thick lining located on the side wall of said body. Thus, transition liner elements avoid the formation of depressions and/or protruding edges in the liner, where the main liner elements having different thicknesses come into contact with each other. The presence of these recesses and/or protruding edges is undesirable, since they can lead to material getting stuck in them and further penetrating through the gap between the main lining elements forming the recess and/or protruding edge.

According to some embodiments, the main lining elements form a bottom lining, a front lining, and two opposite side linings, wherein said at least one non-linear transition lining element comprises at least one corner lining element forming a transition section of the lining between three non-parallel main lining elements, located in the corner of the specified lining and forming, respectively, part of the lower lining, the front lining and one of the two opposite side linings.

According to some embodiments, said main lining elements form a bottom lining, a front lining, and two opposite side linings, wherein said three non-parallel main lining elements from the first pair and the second pair of main lining elements are located in the corner of said lining to form, respectively, part of the bottom lining , a front lining and one of two opposite side linings, wherein said at least one non-linear transitional lining element contains at least one corner lining element forming the first and second transitional sections of the lining between said three non-parallel main lining elements.

According to some embodiments, the corner liner further comprises a third leg extending in a direction of the third leg that is different from the directions of the first and second legs, each of the first, second, and third legs extending from said corner to an adjacent transition liner of said transition liner. . The presence of a third shelf may be advantageous because this shelf allows the corner liner to protect the corner from all sides. In other words, there is no gap in the liner to allow material to hit the corner directly. Moreover, the corner liner may be designed to eliminate the formation of a gap near the edge formed between the various parts of the liner.

According to some embodiments, the corner liner further has a third leg extending in a direction of the third leg that is different from the directions of the first and second legs, wherein the third leg forms a third transitional lining section between the third pair of non-parallel main liners, wherein all three main liners the first, second and third pairs, consisting of the main lining elements, are not parallel to each other, while each of the specified first, second and third shelves extends from the specified corner to the adjacent transition lining element of the specified transition lining elements.

It is understood that at least one non-linear transitional lining element forms at least two transitional sections of the lining between the main lining elements of the first and second pairs of main lining elements. These at least two lining transition sections are formed along the respective transition direction. The transition lining element may have two shelves, that is, the first and second shelves. In such a case, the transition liner forms two transition sections of the lining, namely the first and second transition sections. The first transition lining section is formed along the first transition direction between the first pair of non-parallel main lining elements, and the second transition lining section is formed along the second transition direction between the second pair of non-parallel main lining elements. The first transition direction is different from the second transition direction. The first transitional section of the lining is formed along the surface/by means of the first shelf, and the second transitional section of the lining is formed along the surface/by means of the second shelf.

In the event that the transition liner has a third shelf, which may be the case when the element is a corner element, the transition liner forms three transition lining sections. In addition to the first and second liner transitions, a third liner transition is formed extending along the third transition direction between the third pair of non-parallel main liners. The third jump direction is different from each of the first and second jump directions. Each transition section of the lining is formed along the surface / by means of the corresponding shelf of the transition lining element.

The transition sections of the lining are formed between the main elements of the lining. Each transition lining section is formed between a pair of main lining elements. The main lining elements from each pair of these elements are located on opposite sides of the corresponding shelf. Thus, at least three main lining elements are required to form lining transition sections, wherein said sections are either two transition sections on the surface of two shelves, or three transition sections on the surface of three shelves. Thus, it is understood that each pair of main liners, eg the first pair and the second pair of main liners, may have one main liner in common.

In addition, it will be understood that when using a non-linear transition liner, all directions, namely the direction of the first shelf, the direction of the second shelf (and, in the case of using at least some corner liner elements, also the direction of the third shelf) are located along the same line along the respective edges dump truck body. Thus, the flanges form transition areas between the bottom, side and front linings, respectively.

According to some embodiments, said main lining elements form a bottom lining, a front lining and two opposite side linings, wherein the bottom lining is a non-parallel first and second inclined relative to each other parts of the bottom lining, and at least one non-linear transition lining element contains a wedge-shaped lining an element that forms transition sections of the lining between three non-parallel main lining elements, which are located in the wedge-shaped zone of the specified lining and form, respectively, part of the front lining, the first part of the lower lining and the second part of the lower lining. A wedge-shaped liner may be preferred as it allows the wedge-shaped area to be protected from all sides. In other words, there will be no gap in the lining to allow material to enter the wedge-shaped zone directly.

In some embodiments, the non-parallel directions of the first and second legs extend in a common plane parallel to the front lining.

According to some variants of execution, at least some of these transition lining elements have a concave surface facing inside the body of a mining truck.

The concave surface may be substantially cylindrical along a corresponding portion of the main surface. Concave surfaces may be preferred because they can prevent material from sticking to the edges of a mining truck body and thus help reduce the problem of re-transported cargo.

According to some embodiments, at least one transition lining element of said transition lining elements forms a transition section between at least two non-parallel main lining elements having different thicknesses at their contact boundaries with the transition lining element, wherein said at least one transition the lining element has correspondingly different thicknesses at said contact boundaries to provide smooth transition areas of the lining at said contact boundaries. Having different element thicknesses can be advantageous as this allows a smooth lining surface to be formed even when using main lining elements having different thicknesses.

In some embodiments, at least some of said transition linings have through holes to allow at least one transition lining to be attached to the surface of a mining truck body.

In some embodiments, at least some of said transition liners comprise an elastic material, such as rubber or polyurethane.

In some embodiments, the elastic material comprises rubber or polyurethane.

According to some variants of execution, at least some of these transition lining elements contain a structural element designed to reinforce the transition lining element. The structural element may comprise a steel base plate completely or partially enclosed in a transitional lining element. The use of a structural element may be advantageous, since this element allows to increase the structural integrity of the transition lining elements. In addition, such a structural element can improve the fastening of the transition lining element to the body of a mining truck.

According to the second aspect, the proposed lining for the body of a mining truck, containing

main lining elements extending over the main surfaces of said body, said main surfaces comprising a bottom surface, a front surface and two opposite side surfaces, said main lining elements forming at least a bottom lining extending over said bottom surface, and

transitional lining elements passing over the edge and / or corner sections of the body of a mining truck along the lower lining,

wherein each transition lining element forms a transition section between the bottom lining and at least one of the side surfaces and said front surface, wherein said transition lining elements comprise at least one non-linear transition lining element that has first and second flanges extending in respective non-parallel directions of the first and second flanges, wherein the first flange forms the first transition section of the lining between the first pair of non-parallel main lining elements, and the second shelf forms the second transition section of the lining between the second pair of non-parallel main lining elements,

moreover, three main lining elements of the specified first and second pairs of main lining elements are not parallel to each other.

The second aspect can be considered as an alternative solution to the above problem, with the difference being that the transition lining elements form a transition section of the lining between, on the one hand, the lower lining and, on the other hand, at least one of the side surface and the front surface of the quarry body truck, while in accordance with the first aspect, the transition lining elements form a transition section of the lining between at least two non-parallel main lining elements. Thus, the lining made in accordance with the first and second aspects protects the same edge and corner areas and has common essential features. These two aspects can be combined. Moreover, the concept of the invention can be described in an alternative way: each transitional lining element can form a transitional section of the lining between at least two non-parallel main surfaces of the body of a mining truck. The main lining elements may extend over one or more of these non-parallel surfaces.

According to a third aspect, a transition lining element is provided for use in a lining of a mining truck body, said lining comprising main lining elements that, in use, extend over the surfaces of said body, said transition lining element being intended to form a transition lining section between adjacent main lining elements. elements of the specified lining, and the transitional lining element contains

main surface,

central part,

a first shelf and a second shelf extending from the central part in non-parallel respective directions,

wherein the first shelf has a first end surface passing transversely relative to the direction of the first shelf and connected to the main surface, and the first pair of non-parallel side surfaces extending from the central part to the first end surface and connected to the main surface,

moreover, the second shelf has a second end surface passing transversely relative to the direction of the second shelf and connected to the main surface, and a second pair of non-parallel side surfaces extending from the central part to the second end surface and connected to the main surface,

wherein said first and second end surfaces are intended for connection with mating end surfaces of adjacent transitional lining elements passing in the respective directions of the first and second flanges, and each of said non-parallel side surfaces is intended for connection with mating surfaces of adjacent main lining elements,

wherein said first and second end surfaces are intended for connection with mating end surfaces of adjacent transitional lining elements passing in the respective directions of the first and second flanges, and each of said non-parallel side surfaces is configured to be connected with mating surfaces of adjacent main lining elements,

and the specified first shelf is designed to form the first transition section of the lining in the first transition direction between the first pair of main lining elements connected to the specified first pair of non-parallel side surfaces of the first shelf, and

said second flange is intended to form a second transition section of the lining in a second transition direction different from said first transition direction between the second pair of main lining elements connecting to said second pair of non-parallel side surfaces of the second shelf.

The proposed transition lining element provides at least the following advantages:

- If a transition liner is located in the corner or along the wedge-shaped edge sections of the body of a mining truck, this element can prevent or at least significantly reduce the formation of a gap in the lining located in close proximity to the corner or wedge-shaped section. As a result, the risk of penetration of material inside the body of a mining truck through the gap and thus into the space available under the lining elements and causing an increased risk of damage to the lining and an increase in re-transported cargo can be reduced.

- The non-linear transition liner can be designed to fit into the corner or wedge of a particular mining truck body. Thus, the use of this transition liner simplifies the installation of the liner in the back of a mining truck, since one element can replace two or more separate traditional liner elements.

- The use of transition lining elements makes it possible to form a uniform transition section of the lining between the main lining elements having different thicknesses. For example, transition linings can be used to form a smooth transition between a 15 cm thick lining located on the bottom of a mining truck body and a 10 cm thick lining located on the side wall of said body. Thus, transition liner elements avoid the formation of depressions and/or protruding edges in the liner, where the main liner elements having different thicknesses come into contact with each other. The presence of these recesses and/or protruding edges is undesirable, since they can lead to material getting stuck in them and further penetrating through the gap between the main lining elements forming the recess and/or protruding edge.

According to some embodiments, the first end surface of the first shelf and the second end surface of the second shelf have the same dimensions.

In some embodiments, the cross section of the first flange is the same as the cross section of the second flange, said cross sections being formed orthogonally with respect to the respective directions of the first and second flanges.

In some embodiments, the main surface is at least partially concave.

According to some embodiments, the non-parallel side surfaces of at least one of said first and second flanges have a different, relative to each other, width in the transverse direction with respect to the direction of the respective flange.

In some embodiments, at least some of said non-parallel side surfaces are connected to the main surface of the transition liner at an angle of 90 degrees.

According to some embodiments, the transition lining element further comprises a third flange extending from the central part in the direction of the third flange, and the specified direction of the third shelf is not parallel to the plane formed by the directions of the first and second shelves,

moreover, the transition lining element is a corner lining element designed to form a transition section of the lining between the front lining, side lining and part of the lower lining, while

said third shelf has a third end surface extending transversely with respect to the direction of the third shelf and connected to the main surface, and a third pair of non-parallel side surfaces extending from the central part to the third end surface and connected to the main surface,

said third end surface is intended to be connected to the mating end surface of an adjacent transition lining element extending in said direction of the third shelf, and

said third flange is intended to form a third transition section of the lining in a third transition direction (different from the first transition direction and the second transition direction) between the third pair of main lining elements connected to said third pair of non-parallel side surfaces of the third shelf.

The presence of a third shelf may be preferable, since this shelf allows, by means of a corner lining element, to protect the corner from all sides. In other words, there will be no gap in the liner to allow the material to hit the corner directly. Moreover, the corner liner may be designed so as to avoid the formation of a gap near the edge formed between the different parts of the liner.

According to some embodiments of the corner liner, the direction of the first flange, the direction of the second flange, and the direction of the third flange form angles relative to each other corresponding to a range of angle values from 90° to 110°. You can use increased ranges of angle values, depending on the shape of the body of the mining truck.

According to some embodiments of the corner lining element, the main surface has a first flat surface extending along the third shelf and oriented along the direction of the third shelf.

According to some embodiments of the corner liner, the main surface has a second flat surface extending along the central portion and connected to said first flat surface.

In some embodiments, the transition liner is a wedge-shaped liner designed to form a liner transition between the front liner and two inclined lower liner portions, wherein

said directions of the first and second flanges form a common plane, and

the normal to one of the side surfaces of the first shelf and the normal to one of the side surfaces of the second shelf are parallel to the specified common plane.

The presence of a wedge-shaped liner may be advantageous because it allows the wedge-shaped region to be protected from all sides. In other words, there will be no gap in the lining to allow material to directly enter the wedge.

In some embodiments of the wedge-shaped liner, the transition liner is a wedge-shaped liner designed to form a liner transition between the front liner and two slanted lower liner portions, wherein

the first side surface of the first shelf is connected to the first side surface of the second shelf, and the second side surface of the first shelf is connected to the second side surface of the second shelf.

In some embodiments of the wedge liner, the direction of the first flange and the direction of the second flange form an obtuse angle relative to each other. Said obtuse angle may be 150°-170°.

According to a fourth aspect, a transition liner is provided for use in a mining truck body liner, said liner comprising main liner elements that, in use, extend over surfaces of said body and have a transverse thickness relative to said surfaces, said transition liner being designed to formation of a transition section of the lining between adjacent main lining elements of the specified lining and extends along the longitudinal direction, while the specified transition lining element contains

main surface,

the first end surface and the second end surface located at opposite ends of the transitional lining element, and the specified first and second end surfaces extend across the specified longitudinal direction and are connected to the main surface,

first and second side surfaces passing between the respective first and second end surfaces on both sides of the main surface and connected to this main surface,

wherein the first side surface is not parallel to the second side surface,

the thickness of the transition lining element at the first side surface exceeds the thickness of this element at the second side surface, and

when using a transition lining element, said first and second end surfaces are intended for connection with mating end surfaces of adjacent transition lining elements extending in the longitudinal direction, and each of the first and second side surfaces is intended for connection with mating surfaces of adjacent main lining elements.

The proposed transition lining element has at least the following advantages:

- If a transition lining element is located along the edge sections of the body of a mining truck, this element can prevent or at least significantly reduce the formation of a gap in the lining located in close proximity to the edge section. As a result, the risk of penetration of material inside the body of a mining truck through the gap and thus into the space available under the lining elements and causing an increased risk of damage to the lining and an increase in re-transported cargo can be reduced.

- The transitional lining element can be made in such a way that it matches the edge sections of a particular body of a mining truck. Thus, the use of this transition liner simplifies the installation of the liner in the back of a mining truck, since one element can replace two or more separate conventional liner elements.

- The use of transitional lining elements makes it possible to form a homogeneous transitional section of the lining between the main lining elements having different thicknesses. For example, transition linings can be used to form a smooth transition between a 15 cm thick lining located on the bottom of a mining truck body and a 10 cm thick lining located on the side wall of said body. Thus, transition liner elements avoid the formation of depressions and/or protruding edges in the liner, where the main liner elements having different thicknesses come into contact with each other. The presence of these recesses and/or protruding edges is undesirable, since they can lead to material getting stuck in them and further penetrating through the gap between the main lining elements forming the recess and/or protruding edge.

According to some variants of execution, the main surface contains a concave surface facing inside the body of a mining truck. The concave surface may be substantially cylindrical. A concave surface may be advantageous as it may prevent material from sticking to the edges of a mining truck body and thus help to reduce the problem of re-transported cargo.

According to some embodiments, the transition lining element additionally contains through holes that allow the transition lining element to be attached to the surface of the mining truck body.

In some embodiments, the transition liner contains an elastic material.

In some embodiments, the elastic material is rubber or polyurethane.

In some embodiments, the transition liner further comprises a structural element for reinforcing the transition liner. The use of a structural element may be advantageous, since this element allows to increase the structural integrity of the transition lining elements. In addition, such a structural element can improve the fastening of the transition lining element to the body of a mining truck.

According to some embodiments, the structural element comprises a base plate completely or partially enclosed in a transitional lining element.

According to some embodiments, the transition liner is an edge liner configured to form a transition liner between the front liner and a portion of the bottom liner, or between the side liner and a portion of the bottom liner of a mining truck body.

According to the fifth aspect, a method is proposed for installing a lining for a body of a mining truck, containing main lining elements passing over the main surfaces of the specified body, and transitional lining elements passing over the edge and corner sections of the body of a mining truck, while this method includes steps in which

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Next will be described, with reference to the accompanying drawings, the preferred embodiments of the lining and transition lining elements. Variants of the proposed transition lining element are shown in Fig. 2-5. The proposed transitional lining elements according to have common features.

Some features are common to all preferred embodiments of the transition liner, while other features are common to some of the embodiments. One distinguishing feature is that the transition liner is linear or non-linear. A linear transitional lining usually extends along one dimension. Such a transition liner is the edge liner 400 shown in FIG. 4A or edge liner 500 shown in FIG. 5A. The non-linear transition lining element generally follows a non-linear path. Such a transition liner is the wedge liner 300 shown in FIG. 2A and corner liner 200 shown in FIG. 3A. In the detailed description of the preferred embodiments below, each exemplary embodiment described will be referred to by its own name. However, all exemplary embodiments are transition liners as set forth in the claims. Thus, the present invention should not be limited to the particular form described herein. The present invention is limited only by the appended claims, and other embodiments other than those described below are equally possible without departing from the scope of the claims.

In FIG. 1 shows a lining 100 for a mining truck body 10. Mining truck 1 is typically a rough terrain dump truck for use in heavy duty mining and construction work. During operation, the body 10 of the mining truck 1 will receive a load, such as crushed stone, ore, or the like, from another machine, such as an excavator or a wheel loader. The mining truck 1 can then be used to move the loaded material to other areas within the working area, such as a processing device such as a crusher. Mining dump truck 1 is made with the possibility of turning its body 10 around the pivot axis, made at the end of this dump truck, so that the load can be thrown out of the specified body.

To protect the truck body 10 from damage resulting from loading and unloading heavy material into and out of said truck body, the surfaces of the mining truck body 10 are covered with a lining 100. As shown in FIG. 1, the lining 100 is positioned so that it extends over the interior surfaces of the truck body 10.

In particular, the lining 100 includes the main lining elements 110, passing over the main surfaces of the body 10 of a mining truck. Lining 100 additionally contains transitional lining elements 120 passing over the edge and/or corner sections of the body 10 of a mining truck. Each transition lining element 120 forms a transition section of the lining between at least two non-parallel main lining elements 110 of the specified main lining elements 110. and a second leg 212, 312 extending in respective non-parallel directions 221, 321 and 222, 322 of the first and second legs.

The main liners 110 form two opposite side liners 105a, 105b, a front liner 105c and a bottom liner 105d, 105e. Thus, the entire lining is divided into separate parts covering separate sections. Transition lining elements 120 are designed to connect sections of the main lining elements 110. Transition lining elements 120 are located at the edges and corners of the body 10 of a mining truck. Thus, the transition liners 120 act as a framing that defines the transition areas between adjacent sections of the main liners 110.

One type of non-linear transition liner is shown in FIG. 2 and 2A showing wedge-shaped liner 300. FIG. 2, the wedge-shaped liner 300 is shown as part of the lining 100 of the truck body 10, while in FIG. 2A, said element 300 is shown separately. The wedge liner 300 is a non-linear transition liner and thus has a first leg 311 and a second leg 312 extending in respective non-parallel directions 321 and 322 of the first and second legs.

In the lining 100, the main lining elements 110 form two opposite side linings 105a, 105b, a front lining 105c and a bottom lining 105d, 105e. The lower lining 105d, 105e has non-parallel and inclined relative to each other first and second parts 105d, 105e of the lower lining, and at least one non-linear transitional lining element contains a wedge-shaped lining element 300, forming a transitional section of the lining between three or more non-parallel main lining elements 110 , which are located at the wedge-shaped zone of the lining 100 and form part of the front lining 105c and two non-parallel parts 105d, 105e of the lower lining. The non-parallel directions 321 and 322 of the first and second legs extend in a common plane parallel to the front lining 105c.

The wedge-shaped lining element 300 includes a main surface 305. The main surface 305 is the outer surface facing the material loaded into the body 10 of a mining truck. The main surface 305 includes a first part 301 and a second part 302. The first 301 and the second 302 parts of the main surface are connected to each other.

The wedge-shaped lining element 300 further comprises a central portion 310, as well as a first flange 311 and a second flange 312 extending from the central portion 310 in respective non-parallel directions 321 and 322 of the first and second flanges.

The first shelf 311 has a first end surface 331 extending transversely with respect to the direction 321 of the first shelf and connected to the main surface 305, and the first pair of non-parallel side surfaces 341a, 341b extending from the central part 310 to the first end surface 331 and connected to the main surface 305 .

The second leg 312 has a second end surface 332 extending transversely with respect to the direction 322 of the second leg and connected to the main surface 305, and a second pair of non-parallel side surfaces 342a, 342b extending from the central part 310 to the second end surface 332 and connected to the main surface 305 .

The first main surface portion 301 and the second main surface portion 302 are concave surfaces facing the inside of the mining truck body 10 . The concave surfaces may be substantially cylindrical along a corresponding portion of the main surface. The concave surfaces can prevent material from getting stuck at the edges of the mining truck body 10 and thus help to reduce the problem of re-transported cargo.

The wedge-shaped lining element 300 forms a transition between three or more non-parallel main lining elements having different thicknesses at the contact boundaries of said elements with the transition lining element. Specifically, a transitional lining portion is formed between the front lining 105 c and the two inclined bottom lining portions 105a, 105b. Directions 321 and 322 of the first and second flanges form a common plane, with the normal to one of the side surfaces 341b of the first shelf 311 and the normal to one of the side surfaces 342b of the second shelf 312 parallel to said common plane.

Thus, the wedge-shaped liner 300 has different, appropriate thicknesses at the interfaces to ensure that there are smooth transition areas of the liner along said interfaces. The contact boundaries of the wedge liner 300 correspond to the non-parallel side surfaces 341a, 341b, 342a, 342b.

As can be seen from FIG. 2A, the non-parallel side surfaces 341a, 341b of the first leg 311 and the non-parallel side surfaces 342a, 342b of the second leg 312 are connected to the main surface 305 of the transition liner at a 90 degree angle.

Thus, when using a transition liner 300, the first and second end surfaces 331, 332 are designed to connect with mating end surfaces of adjacent transition liner elements 120 extending in the respective directions 321, 322 of the first and second shelves. Such adjacent transition liner 120 is edge liner 400 shown in FIG. 4A. Each of the non-parallel side surfaces 341a, 341b, 342a, 342b is configured to connect with mating surfaces of adjacent main liners 110.

In order to be able to mate with adjacent transition liners 120, wedge-shaped liners 300 are designed to provide a certain symmetry. Thus, the first end surface 331 of the first shelf 311 and the second end surface 332 of the second shelf 312 have the same dimensions. Moreover, the cross section of the first shelf 311 is the same as the cross section of the second shelf 312, and the cross sections are located orthogonally relative to the respective directions 321 and 322 of the first and second shelves.

The non-parallel side surfaces of at least one of the first and second flanges 311, 312 have different widths W1, W2 relative to each other, extending transversely with respect to the direction of the respective flange. Thus, the wedge-shaped liner 300 is suitable for forming a smooth transition between the main liners 110 having a first thickness W1 and used in the two inclined bottom lining portions 105a, 105b and the main liners having a second thickness W2 and used in the front lining. 105c and two opposite side liners 105a, 105b.

The first side surface 341a of the first shelf 311 is connected to the first side surface 342a of the second shelf 312, and the second side surface 341b of the first shelf 311 is connected to the second side surface 342b of the second shelf 312.

The direction 321 of the first shelf and the direction 322 of the second shelf form an obtuse angle relative to each other. In an exemplary embodiment, this obtuse angle is 160°.

The wedge-shaped lining element 300 additionally contains through holes 350a, 350b, enabling the said element to be attached to the surface of the body 10 of a mining truck. Fastening is provided through the use of through-through anchor bolts or an alternative fastening device through through holes 350a, 350b of wedge liner 300 and into mating through holes in truck body 10. There are two rows of through holes, namely, the bottom row 350b for attaching the wedge liner 300 to the bottom surface of the mining truck body 10, and the top row 350a for attaching the wedge liner 300 to the side surface of said body.

The wedge liner 300 contains an elastic material. In an exemplary embodiment, the wedge liner 300 comprises rubber. Alternatively, polyurethane can be used.

The wedge-shaped liner 300 further includes a structural element 160 for reinforcing this element 300. This structural element is shown in FIG. 6A-6D, which show cross-sectional profiles as viewed along the line VI-VI of FIG. 2A of a wedge-shaped liner 300 made according to four exemplary embodiments. Structural element 160 is a steel base plate, fully or partially enclosed in a transition lining element. In this embodiment, the steel backing plate is embedded within the wedge liner 300 during the vulcanization of the rubber.

In FIG. 7A-7D depict alternative cross-sectional profiles of a wedge-shaped liner made in accordance with alternative exemplary embodiments of the invention. In FIG. 7A shows an embodiment designed to be mounted on the body of a mining truck having sharp body edges. In FIG. 7B and 7D show embodiments designed to mount on a mining truck body with wedge-shaped body edges located at an angle of 45°. In FIG. 7C and 7D show embodiments where the main surface has sharp edges instead of a rounded concave shape.

Another type of non-linear transition liner is the corner liner. In FIG. 3 shows a corner liner 200 in a lining 100 of a mining truck body 10, while FIG. 3A and 3B are views of a single corner liner 200. As shown in FIG. 2, the corner liner 200 forms a liner transition between three non-parallel main liners 110 located at the corner of the liner 100 and forming part of one of two opposing side liners 105a. , 105b, front lining 105c and bottom lining 105d, 105e, respectively.

The corner liner 200 is a non-linear transition liner and thus has a first leg 211 and a second leg 212 extending in respective non-parallel directions 221 and 222 of the first and second legs. In addition, the corner liner 200 further has a third leg 213 extending in a direction 223 of the third leg different from the directions 221 and 222 indicated. 120 of said transition elements 120.

Corner liner 200 includes a main surface 205. Main surface 205 is an outwardly facing surface facing material being loaded onto a mining truck body. The main surface 205 includes a first part 201, a second part 202, and a third part 203. The first 201 and second 202 main surface parts have concave surfaces facing the inside of a mining truck body. The concave surfaces may be substantially cylindrical along a corresponding portion of the main surface. The concave surface can prevent material from sticking to the edges of the dump truck body 10 and thus help to reduce the problem of re-transported cargo.

The main surface 205 has a first flat surface 203, which is the third part 203 of the main surface, passing through the third shelf 213 and oriented along the direction 223 of the third shelf.

The main surface 205 has a second flat surface 204 extending along the central portion 210 and connected to the first flat surface 203. The second flat surface 204 is inclined to prevent the formation of an acute angle on the main surface 205, inside which material can get stuck during the use of the body 10 mining truck.

In other words, the corner liner 200 includes a central portion 210 and a first 211 and a second 212 flange extending from said central portion in respective non-parallel directions 221 and 222 of the first and second flanges. Corner lining element 200 further comprises a third shelf 213 extending from the central part 210 in the direction 223 of the third shelf, while the direction 223 of the third shelf is not parallel to the plane formed by the directions 221 and 222 of the first and second shelves.

The corner liner 200 is designed to form a liner transition between the front liner 105c, the side liner 105a, 105b, and the lower liner portions 105d, 105e.

As shown in FIG. 3A and 3B, the three legs 211, 212, 213 converge with each other and join at the central portion 210.

In other words, the first leg 211 has a first end surface 231 extending transversely with respect to the direction 221 of the first leg and connected to the main surface 205, and a first pair of non-parallel side surfaces 241a, 241b extending from the central portion 210 to the first end surface 231 and connected to main surface 205.

Similarly, the second leg 212 has a second end surface 232 extending transversely with respect to the direction 222 of the second leg and connected to the main surface 205, and a second pair of non-parallel side surfaces 242a, 242b extending from the central part 210 to the second end surface 232 and connected to main surface 205.

Similarly, the third leg 213 has a third end surface 233 extending transversely to the direction 223 of the third leg and connected to the main surface 205, and a pair of non-parallel side surfaces 243a, 243b extending from the central portion 210 to the third end surface 233 and connected to the main surface 205 .

As can be seen from FIG. 3A, the non-parallel side surfaces 241a, 241b of the first leg 211 and the non-parallel side surfaces 242a, 242b of the second leg 212 are connected to the main surface 205 of the transition liner at a 90 degree angle.

Each of the non-linear transition liners, such as corner liners 200 and wedge liners 300, is configured to provide at least two transition liners between at least three non-parallel main liners. This is also illustrated in FIG. 1 for corner member 200 and adjacent main liners 110a-110f. For clarity, the same lining elements are shown in FIG. 10 as individual elements on an enlarged scale. As shown in FIG. 1 and 10, the first leg 211 defines a first transition section L1 between the first pair 110a, 110b of non-parallel main liners. Similarly, the second leg 212 defines a second transition section L2 between the second pair 110a, 110c of non-parallel main liners. All three main liners 110a-110c of the first pair 110a, 110b and the second pair 110a, 110c of main liners are not parallel to each other. One skilled in the art will appreciate that wedge 300 has the same characteristics. However, the corner liner 200 shown in FIG. 1 and 10 further comprises a third leg 213. Accordingly, the third leg 213 similarly defines a third transition portion L3 between the third pair 110b, 110c of non-parallel main liners. For the corner liner 200, all three main liners 110a-110c of the first 110a, 110b, second 110a, 110c, and third main liner pair 110b, 110c are not parallel to each other. This means that for each of said pairs of main liners, one or more specific main liners can be shared.

When using transition lining element 200, the first and second end surfaces 231, 232 are designed to connect with mating end surfaces of adjacent transition lining elements 120 extending in the respective directions 221 and 222 of the first and second shelves. Such adjacent transition liner 120 is edge liner 400 shown in FIG. 4A. Each of the non-parallel side surfaces 241a, 241b, 242a, 242b is designed to connect to the mating surfaces of adjacent main lining elements 110. The third end surface 233 is designed to connect to the mating end surface of the adjacent transition lining element 120, passing in the direction 223 of the third shelf. Such adjacent transition liner 120 is edge liner 500 shown in FIG. 5A.

In order to be able to mate with adjacent transition liners 120, corner liners 200 are configured to provide a certain symmetry. Thus, the first end surface 231 of the first shelf 211 and the second end surface 232 of the second shelf 212 have the same dimensions. Moreover, the cross section of the first shelf 211 is the same as the cross section of the second shelf 212, and the cross sections are located orthogonally relative to the respective directions 221 and 222 of the first and second shelves.

The non-parallel side surfaces of at least one of the first 211 and second 212 shelves have a different, relative to each other, width W1, W2, passing in the transverse direction relative to the direction of the corresponding shelf. Thus, the corner liner 200 is designed to form a smooth transition between the main liners 110 having a first thickness W1 and used in the two inclined bottom lining portions 105a, 105b and the main liners having a second thickness W2 and used in the front lining. 105c and two opposite side liners 105a, 105b.

The direction 221 of the first shelf, the direction 222 of the second shelf and the direction 223 of the third shelf form relative to each other angles corresponding to the range of values from 90° to 110°.

Corner lining element 200 has through holes 250, enabling the specified element to be attached to the surface of the body 10 of a mining truck. Fastening is provided by using through-through anchor bolts or an alternative fastening device that extends through the through holes 250 of the corner liner 200 and then into the mating through holes of the truck body 10 .

Corner liner 200 contains an elastic material. In an exemplary embodiment, corner liner 200 comprises rubber. Alternatively, polyurethane can be used.

Corner liner 200 further comprises a structural element 160 configured to reinforce this element 200. This structural element is shown in FIG. 6A-6D, which show cross-sectional profiles as viewed along the line VI-VI of FIG. 2A of a second leg 212 of a corner liner 200 made according to four exemplary embodiments. Structural member 160 is a steel backing plate completely or partially enclosed within corner liner 200. In this embodiment, the steel backing plate is embedded within corner liner 200 during rubber vulcanization.

In FIG. 7A-7D depict alternative cross-sectional profiles of a second flange 212 of a corner liner made in accordance with alternative exemplary embodiments of the invention. In FIG. 7A shows an embodiment designed to be mounted on the body of a mining truck having sharp body edges. In FIG. 7B and 7D show embodiments designed to mount on a mining truck body with wedge-shaped body edges located at an angle of 45°. In FIG. 7C and 7D show embodiments where the main surface has sharp edges instead of a rounded concave shape.

Another type of transition liner 120 is a linear liner. One view of such a linear transition liner is shown in FIG. 4 and 4A showing edge liner 400. FIG. 4, the edge lining element 400 is shown as part of the lining 100 of the truck body 10, while in FIG. 4A is a view of a single edge liner 400.

The edge lining element 400 is intended for use in a lining 100 for a mining truck body 10 . Lining 100 contains main lining elements 110, which, in use, pass over the surfaces of the body 10 of a mining truck, while the thickness of these elements is oriented transversely relative to the surface. The edge lining element 400 is designed to form a transition section of the lining between adjacent main elements 110 of the lining 100. The edge lining element 400 extends along the longitudinal direction 420.

Edge lining element 400 includes a main surface 405. Said main surface 405 includes a concave surface facing inside the body 10 of a mining truck. This concave surface may be substantially cylindrical. The concave surface can prevent material from sticking to the edges of the dump truck body 10 and thus help to reduce the problem of re-transported cargo.

The edge lining element 400 further comprises a first end surface 431 and a second end surface 432 located at opposite ends of said element 400. The first end surface 431 and the second end surface 432 extend transversely with respect to the longitudinal direction 420 and are connected to the main surface 405.

The edge lining element 400 further comprises a first side surface 440a and a second side surface 440b extending between the first 431 and second 432 end surfaces, respectively, on each side of the main surface 405 and connected to this surface 405. The first side surface 440a is not parallel to the second side surface 440b. The thickness W1 of the transition liner at the first side surface 440a is greater than the thickness W2 of said element at the second side surface 440b. In other words, the non-parallel side surfaces 440a, 440b have different widths W1, W2 relative to each other, measured across the longitudinal direction.

When using the edge lining element 400, the first and second end surfaces 431 and 432 are designed to connect to the mating end surfaces of adjacent transition lining elements 120 extending in the longitudinal direction 420, and each of the first and second side surfaces is designed to connect to the mating surfaces of adjacent main linings. elements 110. In other words, the edge lining element 400 is designed to form a transition section of the lining between the front lining 105c and the bottom lining part 105d, 105e or between the side lining 105a, 105b and the bottom lining part 105d, 105e.

The different thicknesses of the edge lining element 400 at the first side surface 440a and the second side surface 440b allow this element to be used to form a smooth transition between the main lining elements 110 having a first thickness W1 and used in two inclined lower lining parts 105a, 105b, and main liners having a second thickness W2 and used in the front lining 105c and two opposite side linings 105a, 105b.

The edge lining element 400 additionally contains through holes 450a, 450b, which make it possible to attach this element to the surface of the body 10 of a mining truck. Fastening is performed by means of through-through anchor bolts or an alternative fastening device passing through the through holes 450a, 450b of the edge lining element 400 and further into the mating through holes of the body 10 of the mining truck. There are two rows of through holes, namely a bottom row 450b for attaching the edge liner 400 to the bottom surface of the mining truck body 10 and an upper row 450a for attaching the edge lining 400 to the side surface of the mining truck body 10.

Edge lining element 400 contains an elastic material. In this embodiment, the elastic material is rubber. Alternatively, the elastic material may be polyurethane.

Edge lining element 400 further comprises a structural element 160 designed to reinforce this element 400. This structural element is shown in FIG. 6A-6D, which show cross-sectional profiles as viewed along the line VI-VI of FIG. 4A of an edge liner 400 made according to four exemplary embodiments. Structural element 160 is a steel base plate completely or partially enclosed in an edge lining element. In this embodiment, the steel backing plate is embedded within the edge liner 400 during the vulcanization of the rubber.

In FIG. 7A-7D depict alternative cross-sectional profiles of an edge liner made in accordance with alternative exemplary embodiments of the invention. In FIG. 7A shows an embodiment designed to be mounted on the body of a mining truck having sharp body edges. In FIG. 7B and 7D show embodiments designed to mount on a mining truck body with wedge-shaped body edges at an angle of approximately 45°. In FIG. 7C and 7D show embodiments where the main surface has sharp edges instead of a rounded concave shape.

Another type of inline transition liner is shown in FIG. 5A and 5B showing a flat edge liner 500. FIG. 5, a flat edge liner 500 is shown as part of the lining 100 of a mining truck body 10, while in FIG. 5A is a view of a single flat edge liner 500.

The flat edge liner 500 is similar to the edge liner 400, but differs from it in that it is substantially flat. Another difference is that the non-parallel side surfaces 540a, 540b form oblique angles with the main surface 505. For this embodiment, the acute angle values are approximately 45 degrees.

The proposed transition liners 120 can also be used in the absence of one or more side liners. In such embodiments, at least some of the transition liner elements form a transition lining portion between the bottom lining and at least one side surface of the truck body 10'. In other words, a transition liner 120, such as a corner liner, may not actually be a transition liner 120 used between two different main liners 110. This is shown in FIG. 8 showing an alternative lining 100' for a mining truck body 10'.

Lining 100' contains the main lining elements 110, passing through the main surfaces of the body 10' mining truck. The main surfaces comprise a bottom surface 105d', 105e', opposite side surfaces 105a', 105b' and a front surface 105c'. Said main lining elements 110 form at least a lower lining 105d, 105e extending over said lower surface 105d', 105e'. In this example, the main lining elements 110 form the bottom lining 105d, 105e.

Lining 100' further comprises transitional linings 120 extending along the edge and/or corner portions of the mining truck body 10' along the lower lining 105d, 105e. As depicted in FIG. 8, each transition liner 120 defines a transition lining between the bottom lining 105d, 105e and at least one of the side surfaces 105a, 105b and the front surface 105c of the mining truck body 10'.

As shown in this example, a mining truck body 10' may have a protective edge 107 extending along the side surfaces 105a', 105b' and the front surface 105c' to protect the exposed sides of said transition linings 120 from being damaged by material loaded into said body. Transition liners 120 comprise at least one non-linear transition liner 200', 300 that has a first leg 211, 311 and a second leg 212, 312 extending in respective non-parallel first and second leg directions 221, 321 and 222, 322.

One type of transition liner is the corner liner 200'. This corner liner 200' is different from the corner liner 200 shown in FIG. 3, in that it has only two shelves.

Lining 100' shown in FIG. 8 does not have any side linings. It should be understood that alternative embodiments of the lining according to the invention may have one or more side linings. For example, a lining may have a bottom lining and a front lining, but no side linings. In such a case, some transition liner elements 120 may form a transition liner between at least two non-parallel main liners 110, and other transition liner elements 120 may form a transition liner between the bottom lining 105d, 105e and at least one of the side surfaces 105a. ', 105b' and the front surface 105c' of the truck body 10'. In other words, the main liners 110 extending along the bottom surface 105d', 105e' may be complemented by the main liners 110 extending along at least one of the side surfaces 105a', 105b and the front surface 105c' of the mining truck body 10'.

Another exemplary embodiment in which a double-leg corner liner can be used is a mining truck body having vertical edges at right angles at the intersection of the front surface and side surfaces. With this geometric configuration, the main liner elements can converge directly along the vertical edge and therefore no third part is required.

Transition liners 120, comprising a corner liner 200, a wedge liner 300, and an edge liner 400, are designed for use in a mining truck body. Typical dimensions of such bodies are 10-15 meters in length. Thus, transition liners 120 are of significant size. The inner radius of the concave major surface 205, 305, 405 of the exemplary embodiments described above is in the order of 550 mm, while the outer radius is approximately 600 mm. The thickness W1 at the contact boundary with the main lining element 110 located on the lower surface 105d, 105e is 150 mm, and the thickness W2 at the contact boundary with the main lining element 110 located on the side 105a, 105b or front surface 105c is 100 mm. The length of the edge lining element 400 may be about 1.5 meters. Transition liners 120 are pressed and vulcanized in rubber plate presses.

It will be appreciated from the detailed description that the exemplary transition liners 120 are configured to suit a particular mining truck body design. Thus, the exemplary embodiments have rounded bottom surfaces to match the rounded edge portions of a mining truck body surface. Mining truck bodies may differ in design from the mining truck body 10 described herein. For example, the body of a mining truck may have inclined, flat edge portions of the surface. As detailed above with reference to FIG. 7A, 7B, and 7D, the transition liners disclosed herein may have various cross sections to suit a particular mining truck body design.

Next, with reference to FIG. 9A-9E, a method for assembling a lining 100 for a mining truck body 10 will be described. As described above, the lining 100 includes the main lining elements 110, passing along the main surfaces of the body 10 of a mining truck, and transitional lining elements 120, passing along the edge and corner sections of this body. The method includes a number of successive steps.

In one step, a pair of corner liners 200 of said transition liners 120 are positioned in a respective front side corner of a mining truck body 10 (FIG. 9A).

At one stage, a wedge-shaped lining element 300 of the specified transitional lining elements 120 is located in the transition zone between the front surface 105c of the body 10 of a mining truck and two inclined, relative to each other, parts 105d, 105e of the lower surface of the body 10 of a mining truck (Fig. 9B).

In one step, one or more edge liners 400 of said transition liners 120 are positioned between corner liners 200 and wedge-shaped liners 300 to form, together with said element 300, a common transition area between a pair of corner liners 200 (FIG. 9C).

In one step, one or more additional edge liners 400 of said transition liners 120 are positioned between the corner liners 200 and the rear ends of the mining truck body 10 (FIG. 9D).

In this method, the main lining elements 110 are additionally located along the main surfaces of the body 10 of a mining truck (Fig. 9E).

In this method, the main lining elements 110 are additionally attached to the body 10 of a mining truck,

wherein positioning of said main liners 110 is performed (in whole or in part) after all of the transition liners 120 have been positioned so that the transition liners 120 are held geometrically by the attached main liners 110.

In the proposed method, at least some transitional lining elements from the specified transitional lining elements 120 are additionally attached to the body 10 of a mining truck. Fastening is provided by through-through anchor bolts or an alternative fastening device through through holes 250, 350a, 350b, 450a, 450b of the transition liner and then into the mating through holes of the truck body 10.

Two or more of the listed method steps may be performed in a different sequence relative to each other than the one presented herein, unless expressly stated otherwise.

ALTERNATIVE OPTIONS

The embodiment described above and shown in the drawings can be modified in many ways without departing from the scope of the claims.

The length of the shelves along the corresponding direction of the shelf can be different. For example, the corner liner may have a first leg that is longer than the second leg. This is equally true for the wedge liner.

The cross-sectional profile of the shelves can be different. For example, the corner liner may have a first cross-sectional profile for the first flange and a second, different cross-sectional profile for the second flange. This can be useful in situations where it is necessary to use main lining elements with different sizes for different surfaces of a mining truck body. For example, the thickness of the main lining elements on the side surfaces may be less than on the front surface.

The corner liner may have a cross section of the same profile for all three flanges. The corner lining element can be made symmetrical. In this case, edge liners of the same type can be used to connect to all three flanges of the corner liner.
