Description

Technical Field

[0001] The present disclosure relates to a support device for a power unit of a dump truck and a dump truck. Background Art

[0002] In the existing design of mining dump trucks, the support device for the power unit of mining dump trucks adopts a box-shaped structure. With the continuous expansion of the scale of large open-pit mines at home and abroad, the role of large mining dump trucks has become prominent. Under the same production output, large-tonnage mining dump trucks can reduce the number of vehicles used, improve work efficiency and safety, and obtain higher economic benefits. With the continuous increase in the load of mining dump trucks, higher requirements are put forward for their power output components and main structural components. Due to the large load and harsh operating environment of mining dump trucks, the core component, the power output component unit, frequently fails.

[0053] Typical embodiments embodying the features and advantages of the present disclosure will be described in detail in the following description. It should be understood that the present disclosure can have various changes in different embodiments, all of which do not depart from the scope of the present disclosure, and the descriptions and drawings therein are for illustrative purposes in essence and not for limiting the present disclosure.

[0054] In the following description of different exemplary embodiments of the present disclosure, reference is made to the accompanying drawings, which form a part of the present disclosure, and in which different exemplary structures, systems, and steps for implementing various aspects of the present disclosure are shown by way of example. It should be understood that other specific solutions of components, structures, exemplary devices, systems, and steps can be used, and structural and functional modifications can be made without departing from the scope of the present disclosure. Moreover, although terms such as "above", "between", "inside", etc. may be used in this specification to describe different exemplary features and elements of the present disclosure, these terms are used herein only for convenience, for example, according to the directions of the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional direction of the structure to fall within the scope of the present disclosure.

[0055] Refer to Figure 1 , which representatively shows the structural schematic diagram of the power unit support device of the dump truck proposed by the present disclosure. In this exemplary embodiment, the power unit support device of the dump truck proposed by the present disclosure is described by taking the application to a mining dump truck (especially large-tonnage mining dump trucks such as 150 tons and 240 tons, and the weight of the power unit including equipment such as engines and generators can reach 15 tons) as an example. It is easy for those skilled in the art to understand that in order to apply the relevant designs of the present disclosure to other types of dump trucks, various modifications, additions, substitutions, deletions, or other changes are made to the following specific implementation modes, and these changes are still within the scope of the principle of the power unit support device of the dump truck proposed by the present disclosure.

[0056] As Figure 1 shown, in an embodiment of the present disclosure, the power unit support device of the dump truck proposed by the present disclosure includes a first support frame 100 and two second support frames 200. Referring to Figures 2 to 5 , Figure 2 represents an enlarged schematic diagram of part A in Figure 1 ; Figure 3 represents a partially enlarged schematic diagram in Figure 1 , in which the partial enlarged structure of the power unit support device of the dump truck when the support wheel assembly 300 is installed is specifically designed; Figure 4 represents the structural schematic diagram of the support wheel assembly 300;Figure 5 is representatively shown Figure 3 a schematic diagram of the shown partial structure, in which specifically shown is Figure 3 the structure after the support wheel assembly 300 is hidden. The following will, in conjunction with the above-mentioned drawings, elaborate in detail on the structures, connection manners, and functional relationships of the main components of the support device for the power unit of the dump truck proposed in the present disclosure.

[0057] As Figure 1 shown, in an embodiment of the present disclosure, the first support frame 100 includes two main beams 110 and a connecting beam 120. These two main beams 110 are arranged at intervals along the transverse direction of the dump truck (for example, referring to the direction D1 in the attached drawings), and the cross-section of the main beam 110 is in the shape of an I-beam. The connecting beam 120 is connected between the two main beams 110. Two second support frames 200 are respectively connected to the same ends of the two main beams 110 along the longitudinal direction of the dump truck. For example, with reference to the front and rear in the longitudinal direction of the dump truck (for example, referring to the direction D2 in the attached drawings), the two second support frames 200 can be respectively a left rear support frame located at the left rear of the first support frame 100 and a right rear support frame located at the right rear of the first support frame 100. Through the above design, the present disclosure adopts a three-body assembly design of the first support frame 100 and the two second support frames 200, which can make the support device easy to assemble, disassemble, and repair. Moreover, the present disclosure uses the main beam 110 with an I-beam cross-section to form the first support frame 100, which can meet the installation requirements and improve the structural strength of the support device, and is not prone to cracks or fractures. Accordingly, the support device for the power unit of the dump truck can achieve a long service life and good reliability, and on this basis, achieve weight reduction. In particular, the present disclosure is suitable for bearing a large load, a long working duration, and a relatively harsh working environment.

[0058] As Figure 1 and Figure 2 shown, in an embodiment of the present disclosure, the main beam 110 may include two first flat plates 111, a first vertical plate 112, and a first rib plate 113. Specifically, these two first flat plates 111 are arranged at intervals up and down. The first vertical plate 112 is connected between the two first flat plates 111. Accordingly, grooves are respectively formed on both sides of the main beam 110 (i.e., both sides of the "I" shape). The first rib plate 113 is at least partially located in the above-mentioned grooves, and the first rib plate 113 is respectively connected to the opposite surfaces of the two first flat plates 111 and the side surface of the first vertical plate 112. Through the above design, the present disclosure can use the first rib plate 113 to improve the structural strength of the main beam 110, further extend the service life of the support device, and further improve the reliability.

[0059] As Figure 2As shown, based on the design that the main beam 110 includes the first rib plate 113, in an embodiment of the present disclosure, a first rib plate 113 may be provided at the position where the main beam 110 is connected to the connecting beam 120. On this basis, the first rib plate 113 may further extend transversely to be connected to the connecting beam 120. Through the above design, the present disclosure can utilize the first substrate to improve the structural strength of the connection between the main beam 110 and the connecting beam 120, further extend the service life of the support device, and further improve the reliability.

[0060] As Figure 1 shown, in an embodiment of the present disclosure, the first support frame 100 may include at least two connecting beams 120, such as but not limited to the two connecting beams 120 shown in the drawings, and these connecting beams 120 are arranged at intervals along the longitudinal direction of the dump truck. Through the above design, the present disclosure can further improve the structural strength of the first support frame 100, further extend the service life of the support device, and further improve the reliability. In some embodiments, the first support frame 100 may also include only one connecting beam 120. At this time, the connecting beam 120 may be connected between the middle positions of the two main beams 110. The so-called middle position can be understood as the position other than the end, and is not limited to the middle position or the central position. In other words, the first support frame 100 may also be in an H shape, not limited to this embodiment.

[0061] As Figure 1 shown, based on the design that the first support frame 100 includes at least two connecting beams 120, in an embodiment of the present disclosure, a connecting beam 120 may be connected between the respective ends of the two main beams 110 that are connected to the two second support frames 200. In addition, since at least two connecting beams 120 are arranged at intervals along the longitudinal direction, the other connecting beams 120 can be connected between the middle positions of the two main beams 110 or between the respective other ends of the two main beams 110. Through the above design, the present disclosure can utilize the connecting beam 120 to improve the structural strength of the connection between the main beam 110 and the second support frame 200, ensure the connection reliability and stability between the first support frame 100 and the second support frame 200, and further extend the service life of the support device.

[0062] As Figure 1 shown, in an embodiment of the present disclosure, the second support frame 200 may include a second vertical plate 210, at least one second flat plate 220 and a second rib plate 230. Specifically, the second flat plate 220 is connected to the side of the second vertical plate 210 facing away from the other second support frame 200, such as the outer side of the second vertical plate 210 shown in the drawings. The second rib plate 230 is connected between the second vertical plate 210 and the second flat plate 220. Through the above design, the present disclosure can utilize the second rib plate 230 to improve the structural strength of the second support frame 200, further extend the service life of the support device, and further improve the reliability.

[0063] In an embodiment of the present disclosure, each part of the main beam 110 (such as the first flat plate 111, the first vertical plate 112, the first rib plate 113, etc.) can be made of high-strength steel plate, and the connecting beam 120 can also be made of high-strength steel plate.

[0064] In an embodiment of the present disclosure, each part of the second support frame 200 (such as the second flat plate 220, the second vertical plate 210, the second rib plate 230, etc.) can be made of castings.

[0065] In an embodiment of the present disclosure, the main beam 110 and the second support frame 200 can be connected by welding. For example, the following first connecting plate 114 and the second connecting plate 240 can be connected by welding.

[0066] As Figure 1 , Figure 3 and Figure 4 shown, in an embodiment of the present disclosure, an arched beam (not shown in the drawings) is connected above the first support frame 100. Accordingly, when the power unit of the dump truck is arranged on the dump truck power unit support device, it needs to pass under the arched beam. Specifically, when arranging the power unit on the dump truck power unit support device, first use a lifting device to lift the power unit above the support device and at a position on one side of the arched beam. Due to the obstruction of the arched beam, it is necessary to release the lifting of the power unit and move the power unit so that a part of it passes through the arched beam, and then lift it again. For example, when one end of the power unit passes through the arched beam, that is, the lifting lug provided at this end is no longer blocked by the arched beam, it can be lifted again. Finally, the power unit partially passing through the arched beam is lifted to a predetermined position by the lifting device and then installed with the support device. On this basis, the dump truck power unit support device proposed by the present disclosure may further include a support wheel assembly 300. The support wheel assembly 300 is detachably arranged on the main beam 110 or the second support frame 200. The support wheel assembly 300 is used to support the power unit and enable it to slide longitudinally through the arched beam. Through the above design, when releasing the lifting and it is necessary to move the power unit, the present disclosure can use the support wheel assembly 300 to provide rolling support for the power unit. Accordingly, the operator can move the power unit more labor-savingly, reduce the assembly difficulty and improve the assembly efficiency. In addition, each support wheel assembly 300 adopted by the present disclosure can support a weight of up to 20 tons, and the manufacturing cost is relatively low.

[0067] As Figure 1As shown, based on the design of the support device for the power unit of the dump truck including the support wheel assembly 300, in an embodiment of the present disclosure, the support wheel assemblies 300 can be respectively arranged on both sides of the dump truck in the transverse direction, such as the two support wheel assemblies 300 shown in the attached drawings. Through the above design, the present disclosure can further optimize the effect of the support wheel assembly 300 providing rolling support for the power unit, further reducing the assembly difficulty and improving the assembly efficiency.

[0068] As Figure 3 and Figure 4 As shown, based on the design of the support device for the power unit of the dump truck including the support wheel assembly 300, in an embodiment of the present disclosure, the support wheel assembly 300 can include a support plate 310 and a roller 320. Specifically, the support plate 310 is detachably arranged on the main beam 110 or the second support frame 200 via a first fastener 312. The roller 320 is rotatably connected to the support plate 310 via a pin shaft 321. Through the above design, the present disclosure can specifically realize the detachable arrangement mode of the support wheel assembly 300 on the main beam 110 or the second support frame 200, with a simple structure and convenient operation. On this basis, during the assembly process of the power unit, for example, when the power unit moves to a predetermined position, the support wheel assembly 300 can be removed. Then, in the dump truck product adopting the design of the present disclosure, the support wheel assembly 300 may not exist. Of course, the design of the support wheel assembly 300 of the present disclosure can still be understood based on the relevant structures (such as the following first assembly hole 1143, third assembly hole, etc.) provided on the main beam 110 or the second support frame 200 for installing the support wheel assembly 300 in the dump truck product.

[0069] As Figure 4 As shown, based on the design of the support wheel assembly 300 including the support plate 310, in an embodiment of the present disclosure, a through hole 313 can be provided at the top of the support plate 310. The through hole 313 can be used as a handle when the operator lifts and transports the support wheel assembly 300, and at the same time can be used as a weight-reducing hole to reduce the weight of the support wheel assembly 300, further reducing the operation difficulty.

[0070] As Figures 3 to 5As shown, based on the design that the support plate 310 is arranged on the main beam 110 or the second support frame 200 via the first fastener 312, in an embodiment of the present disclosure, a first connection plate 114 may be arranged at one end of the main beam 110 connected to the second support frame 200, and a second connection plate 240 may be arranged at one end of the second support frame 200 connected to the main beam 110. One side surface of the first connection plate 114 facing the second connection plate 240 has a first area 1141 and a second area 1142, and the main beam 110 and the second support frame 200 are connected via the first area 1141 of the first connection plate 114 and the second connection plate 240. For example, the first area 1141 can be understood as the area where the second connection plate 240 has a positive projection on the first connection plate 114. On this basis, the first connection plate 114 may be provided with a first assembly hole 1143, and the first assembly hole 1143 is located in the above-mentioned second area 1142. For example, one end orifice of the first assembly hole 1143 is located in the second area 1142. The support plate 310 may be provided with a second assembly hole 311. The first assembly hole 1143 and the second assembly hole 311 are arranged in corresponding positions, and the above-mentioned first fastener 312 is inserted through the first assembly hole 1143 and the second assembly hole 311 to detachably fix the support plate 310 to the above-mentioned first area 1141 of the first connection plate 114 via the first fastener 312. In some other embodiments of the present disclosure, the support plate 310 may also be detachably fixed to the side of the first connection plate 114 facing away from the second connection plate 240 via the first fastener 312.

[0071] As Figure 3 and Figure 4 shown, in an embodiment of the present disclosure, the first fastener 312 may be a bolt.

[0072] As Figure 3 and Figure 4 shown, in an embodiment of the present disclosure, for a support wheel assembly 300, it may be arranged on the main beam 110 via a plurality of first fasteners 312. Correspondingly, the above-mentioned first assembly holes 1143 and second assembly holes 311 may both be a plurality corresponding in quantity.

[0073] As Figure 3 shown, in an embodiment of the present disclosure, the first connection plate 114 and the second connection plate 240 may be respectively provided with other assembly holes corresponding in position, and accordingly, the main beam 110 and the second support frame 200 are connected by using a second fastener 1144 (such as but not limited to a bolt) inserted through these assembly holes.

[0074] As Figure 5As shown, in an embodiment of the present disclosure, a notch positioning structure may be provided between the first connecting plate 114 and the second connecting plate 240, and thereby the positioning and connection of the main beam 110 and the second support frame 200 can also be achieved. Specifically, the notch positioning structure may include a mating protrusion and groove. For example, a protrusion 1145 may be provided in a first area 1141 on a surface of the first connecting plate 114 facing the second connecting plate 240. Correspondingly, a groove 241 may be provided on a surface of the second connecting plate 240 facing the first connecting plate 114, and the position of the groove 241 corresponds to the position of the protrusion 1145. Accordingly, when the main beam 110 and the second support frame 200 are connected via the first connecting plate 114 and the second connecting plate 240, the protrusion 1145 is received in the groove 241, and thereby the relative position of the two connecting plates can be limited and maintained. Furthermore, the protrusion 1145 and the groove 241 may be designed to extend in the horizontal direction, and thereby the assembly operation of the sliding assembly of the first connecting plate 114 and the second connecting plate 240 in the horizontal direction can be achieved. For example, first slide and assemble in place and then use the second fastener 1144 to fixedly connect. In addition, in some other embodiments of the present disclosure, based on the design of the notch positioning structure, the setting positions of the protrusion and the groove may be interchanged, and it is not limited to this embodiment.

[0075] It should be noted here that the dump truck power unit support devices shown in the drawings and described in this specification are only a few examples of many support devices that can adopt the principles of the present disclosure. It should be clearly understood that the principles of the present disclosure are by no means limited to any details or any components of the dump truck power unit support devices shown in the drawings or described in this specification.

[0076] In summary, the dump truck power unit support device proposed by the present disclosure includes a first support frame 100 and two second support frames 200; the first support frame 100 includes two main beams 110 and a connecting beam 120; the two main beams 110 are arranged at intervals in the transverse direction of the dump truck, and the cross-section of the main beam 110 is an I-shaped; the connecting beam 120 is connected between the two main beams 110; the two second support frames 200 are respectively connected to the same ends of the two main beams 110 in the longitudinal direction of the dump truck. Through the above design, the present disclosure adopts a three-body assembly design of the first support frame 100 and the two second support frames 200, which can make the support device easy to assemble and disassemble for maintenance. Moreover, the present disclosure uses the main beam 110 with an I-shaped cross-section to form the first support frame 100, which can improve the structural strength of the support device, and cracks or fractures are not likely to occur. Accordingly, the dump truck power unit support device can achieve a long service life and good reliability, and on this basis, weight reduction can be achieved. In particular, the present disclosure is suitable for bearing a large load, a long working duration and a relatively harsh working environment.
