[0001] The utility model relates to the technical field of electric LHD accessories, and particularly relates to a carrying roller for an electric LHD. Background Technique
[0002] An electric LHD belongs to underground mining equipment. The cable carrying roller on it needs to take in and pay out the cable during the operation of the electric LHD. Therefore, the cable carrying roller wears out relatively quickly and needs to be replaced frequently. Since the electric LHD usually operates underground, the replacement of the cable carrying roller is often completed underground.
[0003] During actual replacement, the operator needs to first take the carrying roller of the electric LHD to the underground, and then the replacement of the carrying roller of the electric LHD can be carried out. However, due to the relatively long overall length of the existing carrying roller of the electric LHD, it is very inconvenient to take it from the ground to the underground. It is too labor-consuming and the taking difficulty is also relatively large.
[0004] Therefore, it is very necessary to invent a carrying roller for an electric LHD to solve the above problems. Content of the Utility Model
[0005] The purpose of the utility model is to provide a carrying roller for an electric LHD, which can be taken from the ground to the underground in a shortened state. After being taken to the underground, the hexagonal bolt is rotated from the inside of the threaded groove and the outer sleeve roller is pulled to expand and use the product, so as to solve the problem that the existing carrying roller of the electric LHD is relatively long in the prior art, so it is very inconvenient to take it from the ground to the underground, which is too labor-consuming and the taking difficulty is also relatively large.

[0021] Figure 3 is a structural schematic diagram of the limiting plate 12 of the idler roller of a battery-powered LHD according to an embodiment of the present disclosure.
[0022] The specific reference numerals in the drawings are as follows:
[0023] Middle roller member; 11, intermediate roller; 12, limiting plate; 13, threaded groove; 14, hexagon bolt;
[0024] Extension roller parts; 21. Outer sleeve roller; 22. Bearing; 23. Rotating shaft. Detailed implementation manners
[0025] The present disclosure will be further described in detail below with reference to the accompanying drawings and implementation manners. It can be understood that the specific implementation manners described herein are only used to explain the relevant content and do not limit the present disclosure. Additionally, it should be noted that for the sake of description, only the parts related to the present disclosure are shown in the drawings.
[0026] It should be noted that, without conflict, the implementation manners in the present disclosure and the features in the implementation manners can be combined with each other. The technical solutions of the present disclosure will be described in detail below with reference to the drawings and implementation manners.
[0027] Unless otherwise specified, the exemplary implementation manners / embodiments shown will be understood to provide exemplary features of various details of some ways that can implement the technical concept of the present disclosure in practice. Therefore, unless otherwise specified, without departing from the technical concept of the present disclosure, the features of various implementation manners / embodiments can be additionally combined, separated, interchanged, and / or rearranged.
[0028] In the drawings, cross-hatching and / or shading are generally used to make the boundaries between adjacent components clear. Thus, unless stated otherwise, the presence or absence of cross-hatching or shading does not convey or imply any preference or requirement for the specific material, material properties, dimensions, proportions, commonality between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. Additionally, in the drawings, for the purpose of clarity and / or description, the dimensions and relative dimensions of the components may be exaggerated. When the exemplary embodiments can be implemented differently, the specific process sequences can be performed in a different order than described. For example, two consecutively described processes can be performed substantially simultaneously or in an order opposite to the described order. Moreover, the same reference numerals denote the same components.
[0029] When a component is referred to as being "on" or "above" another component, "connected to" or "coupled to" another component, the component can be directly on the other component, directly connected to or directly coupled to the other component, or there can be an intermediate component. However, when the component is referred to as being "directly on" another component, "directly connected to" or "directly coupled to" another component, there is no intermediate component. For this reason, the term "connection" can refer to a physical connection, an electrical connection, etc., and can have or not have an intermediate component.
[0030] For descriptive purposes, the present disclosure may use spatial relative terms such as "under", "below", "beneath", "lower", "above", "upper", "on", "higher", and "side (e.g., as in "sidewall")" to describe the relationship of one component to another (other) component as shown in the figures. In addition to the orientation depicted in the figures, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the figures is flipped, a component described as "under" or "beneath" another component or feature will then be positioned "above" the other component or feature. Thus, the exemplary term "under" can encompass both "above" and "below" orientations. In addition, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptors used herein are to be interpreted accordingly.
[0031] The terms used herein are for the purpose of describing particular embodiments and are not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are also intended to include the plural forms. In addition, when the terms "comprise" and / or "include" and their variations are used in this specification, it is stated that there are the stated features, integers, steps, operations, components, assemblies, and / or groups thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, assemblies, and / or groups thereof. It should also be noted that, as used herein, the terms "substantially", "about", and other similar terms are used as approximate terms and not as terms of degree, and thus are used to explain the inherent deviations of measured, calculated, and / or provided values that would be recognized by a person of ordinary skill in the art.
[0032] Figure 1 is a schematic diagram of the overall structure of an electric LHD idler according to an embodiment of the present disclosure.
[0033] Figure 2 is a schematic diagram of the structure of the middle roller member 1 and the extension roller member 2 of an electric LHD idler according to an embodiment of the present disclosure.
[0034] Figure 3 is a schematic diagram of the structure of the limit plate 12 of an electric LHD idler according to an embodiment of the present disclosure.
[0035] As Figures 1 - 3 shown, the electric LHD idler of the present disclosure may include components such as a middle roller member 1 and an extension roller member 2.
[0036] As Figure 2As shown, in the present disclosure, the middle roller member 1 includes an intermediate roller 11, a limit plate 12, a threaded groove 13, and a hexagon bolt 14. Among them, the limit plate 12 is fixedly arranged at the end of the intermediate roller 11, the threaded groove 13 is opened on the side of the limit plate 12 away from the intermediate roller 11, and the hexagon bolt 14 is threadedly connected to the inside of the threaded groove 13.
[0037] Thus, by rotating the hexagon bolt 14, the end of the hexagon bolt 14 is removed from the inside of the threaded groove 13. At this time, the extension roller member 2 is no longer locked, and then the extension roller member 2 can be pulled and unfolded, increasing the overall length of the product. In addition, during the process of pulling and unfolding the extension roller member 2, the limit plate 12 continuously slides inside the outer sleeve roller 21. When the inner wall of the outer sleeve roller 21 contacts the outer wall of the limit plate 12, the extension roller member 2 is fully unfolded.
[0038] As Figure 1 shown, in a preferred embodiment, the extension roller member 2 includes an outer sleeve roller 21, a bearing 22, and a rotating shaft 23. Among them, the outer sleeve roller 21 is slidably sleeved on the outside of the intermediate roller 11 and the limit plate 12. A limit sliding groove is opened inside the outer sleeve roller 21, and the limit plate 12 is slidably nested inside the limit sliding groove. The bearing 22 is fixedly nested at the end of the outer sleeve roller 21. The outer ring of the bearing 22 is fixedly connected to the outer sleeve roller 21. The rotating shaft 23 is fixedly arranged inside the bearing 22 and fixedly connected to the inner ring of the bearing 22. A threaded channel is penetrated through the rotating shaft 23, and the hexagon bolt 14 is threadedly connected to the inside of the threaded channel.
[0039] Thus, during the process of the outer sleeve roller 21 sliding on the outside of the intermediate roller 11, the limit plate 12 located inside the limit sliding groove functions as a limit to prevent the outer sleeve roller 21 from directly detaching from the surface of the intermediate roller 11. At the same time, the threaded channel inside the rotating shaft 23 can accommodate the hexagon bolt 14 to prevent the end of the hexagon bolt 14 from being lost due to lack of fixation after being removed from the inside of the threaded groove 13.
[0040] In the description of this specification, the description with reference to terms such as "one embodiment / way", "some embodiments / ways", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment / way or example are included in at least one embodiment / way or example of the present application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment / way or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments / ways or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments / ways or examples described in this specification and the features of different embodiments / ways or examples.
[0041] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.
[0042] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present disclosure and are not intended to limit the scope of the present disclosure. For those skilled in the art, other changes or modifications can be made based on the above disclosure, and these changes or modifications are still within the scope of the present disclosure.
