[0037] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0038] Mining dump trucks are widely used in mining and transportation because of their high carrying capacity and short travel distance. Large-tonnage electric dump trucks are the current development direction. The larger the tonnage, the higher the strength and safety requirements for the frame. At the same time, the weight and size of the frame are larger, so the frame will also cause difficulties in transportation and packaging, increasing enterprise costs.

[0039] The existing frames are generally suitable for small-tonnage and small-sized vehicles, and are limited in application scenarios and have limited structural strength. Therefore, they are not suitable for mining dump trucks that are larger in weight and size.

[0040] In order to solve at least one of the technical problems existing in the prior art or related technologies, the present utility model provides an extended beam assembly. The extended beam assembly includes a reinforcing beam, a front suspension connection seat, a positioning component, and a connection component. One side of the front suspension connection seat is connected to the reinforcing beam; the positioning component is used to position the side of the front suspension connection seat away from the reinforcing beam at a target position on the vehicle frame; the connection component is used to detachably fix the front suspension connection seat located at the target position on the vehicle frame. Thus, it can be seen that by adding the positioning component, the present application can ensure the position accuracy of the extended beam assembly when installed on the vehicle frame, and at the same time, it is also convenient for the assembly of the extended beam assembly on the vehicle frame to change the size of the vehicle frame. During the transportation of the dump truck, the extended beam assembly can be transported separately, and when the size of the vehicle frame needs to be extended, the extended beam assembly can be quickly assembled onto the vehicle frame, which is convenient for the transportation of the extended beam assembly and reduces the transportation cost of the extended beam assembly, thereby reducing the transportation cost of the vehicle frame.

[0041] The following describes an extended beam assembly and a dump truck according to some embodiments provided by the present utility model with reference to the accompanying drawings.

[0042] See Figures 1 to 4 , an extended beam assembly according to an embodiment provided by the present utility model is applied to a dump truck. The extended beam assembly includes a reinforcing beam 1, a front suspension connection seat 2, a positioning component, and a connection component. One side of the front suspension connection seat 2 is connected to the reinforcing beam 1; the positioning component is used to position the side of the front suspension connection seat 2 away from the reinforcing beam 1 at a target position on the vehicle frame 3; the connection component is used to detachably fix the front suspension connection seat 2 located at the target position on the vehicle frame 3.

[0043] Here, the target position can be located at a position close to the side part of the vehicle frame 3.

[0044] When installing the extended beam assembly on the vehicle frame 3, first position the front suspension connection seat 2 on the vehicle frame 3 at the target position through the positioning component, and then fix the front suspension connection seat 2 located at the target position on the vehicle frame 3 through the connection component, so as to realize the installation of the extended beam assembly on the vehicle frame 3.

[0045] In this embodiment, by designing the extended beam assembly and the vehicle frame 3 as a split structure, positioning the side of the front suspension connection seat 2 away from the reinforcing beam 1 at the target position on the vehicle frame 3 through the positioning assembly, and then detachably fixing the front suspension connection seat 2 located at the target position on the vehicle frame 3 by using the connection assembly, the installation of the extended beam assembly at the target position on the vehicle frame 3 can be completed. It can be seen that in this application, by adding a positioning assembly, while ensuring the position accuracy of the installation of the extended beam assembly on the vehicle frame 3, it is also convenient for the assembly of the extended beam assembly on the vehicle frame 3 to change the size of the vehicle frame 3. During the transportation of the dump truck, the extended beam assembly can be transported separately, and when the size of the vehicle frame 3 needs to be extended, the extended beam assembly can be quickly assembled onto the vehicle frame 3, which is convenient for the transportation of the extended beam assembly and reduces the transportation cost of the extended beam assembly, thereby reducing the transportation cost of the vehicle frame 3.

[0046] In some possible embodiments, the front suspension connection seat 2 includes a seat body 201 and a connecting plate 202. One side of the seat body 201 is connected to the reinforcing beam 1, the side of the seat body 201 away from the reinforcing beam 1 is connected to the connecting plate 202, and a plurality of connecting holes are distributed on the connecting plate 202; the connection assembly includes a plurality of bolt members 4, and the connecting plate 202 is fixed on the vehicle frame 3 through the cooperation of the plurality of bolt members 4 and the plurality of connecting holes.

[0047] It should be noted that the bolt members 4 can be 10.9 grade high-strength bolts.

[0048] Here, the length direction of the reinforcing beam 1 is parallel to the length direction of the seat body 201; the length direction of the seat body 201 can be perpendicular to the plane where the connecting plate 202 is located; the plane where the side portion of the seat body 201 connected to the reinforcing beam 1 is located is parallel to the plane where the connecting plate 202 is located.

[0049] In this embodiment, by the cooperation of the plurality of bolt members 4 and the plurality of connecting holes, the seat body 201 is fixed at the target position on the vehicle frame 3, which can not only detachably fix the front suspension connection seat 2 on the vehicle frame 3, improve the connection flexibility between the front suspension connection seat 2 and the vehicle frame 3, and facilitate the disassembly and replacement of the front suspension connection seat 2, but also, by distributing a plurality of connecting holes on the connecting plate 202, the connection strength of the front suspension connection seat 2 on the vehicle frame 3 can be improved under the cooperation of the plurality of bolt members 4 and the plurality of connecting holes, so that the front suspension connection seat 2 is stably installed on the vehicle frame 3.

[0050] Furthermore, the seat body 201 and the connecting plate 202 are an integrally formed structure.

[0051] In this embodiment, by selecting the seat body 201 and the connecting plate 202 as an integrally formed structure, the connection between the seat body 201 and the connecting plate 202 is eliminated, which can ensure the overall strength of the front suspension connection seat 2 and is also convenient for the batch processing of the front suspension connection seat 2.

[0052] Further, the seat body 201 and the connecting plate 202 are integrally formed by casting.

[0053] In this embodiment, by selecting the casting method to obtain the integral structure of the seat body 201 and the connecting plate 202, it is not only convenient for batch processing of the front suspension connecting seat 2, but also can improve the overall strength of the front suspension connecting seat 2, thereby improving the strength of the entire extended beam assembly.

[0054] Furthermore, the seat body 201 is a hollow structure formed by sequentially connecting a first side plate 2011, a top plate 2012, and a second side plate; the size of the side of the seat body 201 connected to the connecting plate 202 is larger than the size of the side of the seat body 201 connected to the reinforcing beam 1.

[0055] It should be noted that the size of the side of the seat body 201 connected to the connecting plate 202 is larger than the size of the side of the seat body 201 connected to the reinforcing beam 1, which can make the contact area between the connecting plate 202 and the vehicle frame 3 larger than the contact area between the connecting plate 202 and the vehicle frame 3 when the seat body 201 is a cube, so that the seat body 201 can be more stably fixed on the vehicle frame 3.

[0056] Here, selecting the seat body 201 to be a hollow structure formed by sequentially connecting a first side plate 2011, a top plate 2012, and a second side plate can reduce the weight of the seat body 201, and thus reduce the weight of the entire extended beam assembly.

[0057] Still further, the first side plate 2011 and the second side plate are arranged in parallel, a first through hole 2013 is provided on the first side plate 2011, a second through hole is provided on the second side plate, and the first through hole 2013 and the second through hole are arranged opposite to each other.

[0058] Here, both the first through hole 2013 and the second through hole are processed during the casting process of the front suspension connecting seat 2.

[0059] In this embodiment, by providing the first through hole 2013 on the first side plate 2011 and the second through hole on the second side plate, the weight of the seat body 201 can be reduced, and thus the weight of the entire extended beam assembly can be reduced.

[0060] In some possible embodiments, the front suspension connecting seat 2 and the reinforcing beam 1 are connected by welding.

[0061] Here, by connecting the front suspension connecting seat 2 and the reinforcing beam 1 by welding, a fixed connection between the separately manufactured front suspension connecting seat 2 and the reinforcing beam 1 can be achieved, and the strength of the entire extended beam assembly can be improved after the front suspension connecting seat 2 and the reinforcing beam 1 are connected by welding.

[0062] In some possible embodiments, the reinforcing beam 1 is a hollow structure formed by sequentially connecting a first beam plate 101, a second beam plate 102, a third beam plate, and a fourth beam plate; a connecting member 103 is provided on the reinforcing beam 1, and the connecting member 103 is used to detachably mount the platform of the dump truck on the reinforcing beam 1.

[0063] Here, the first beam plate 101 is connected to the first side plate 2011, the second beam plate 102 is connected to the top plate 2012, the third beam plate is connected to the second side plate, and the first beam plate 101 and the first side plate 2011 are located on a first plane, the second beam plate 102 and the top plate 2012 are located on a second plane, the third beam plate and the second side plate are located on a third plane, wherein the first plane and the third plane are parallel, and both the first plane and the third plane are perpendicular to the second plane.

[0064] It should be noted that the first beam plate 101, the second beam plate 102, the third beam plate, and the fourth beam plate are sequentially connected by welding; the connecting member 103 is fixed on the reinforcing beam 1 by welding; wherein, bolt holes are provided on the connecting member 103, and the platform of the dump truck is connected to the platform of the dump truck through the cooperation of bolt assemblies and bolt holes, so as to mount the platform of the dump truck on the lengthened beam assembly.

[0065] In this embodiment, by selecting the reinforcing beam 1 as a hollow structure formed by sequentially connecting a first beam plate 101, a second beam plate 102, a third beam plate, and a fourth beam plate, the weight of the reinforcing beam 1 can be reduced, and further the overall weight of the lengthened beam assembly can be reduced.

[0066] In some possible embodiments, the positioning assembly includes a first groove, a second groove, and a positioning block 5. The first groove is opened on the side of the front suspension connecting seat 2 away from the reinforcing beam 1; the positioning block 5 can be inserted into the first groove; the second groove is opened at a target position on the vehicle frame 3; after the front suspension connecting seat 2 is placed at the target position, a positioning groove is formed between the second groove and the first groove, and the positioning block 5 inserted in the first groove can be inserted in cooperation with the second groove so that the positioning block 5 is embedded in the positioning groove.

[0067] Here, the positioning block 5 can be made of cast iron.

[0068] Exemplarily, there can be at least two positioning assemblies, that is, two first grooves are opened on the side of the front suspension connecting seat 2 away from the reinforcing beam 1, two second grooves are opened at the target position on the vehicle frame 3, and the length directions of the two first grooves are parallel to each other.

[0069] In this embodiment, after the front suspension connecting seat 2 is placed near the target position, the positioning block 5 is inserted into the first groove, and then the positioning block 5 inserted into the first groove is inserted into the second groove, so that the positioning block 5 is located in the positioning groove formed by the second groove and the first groove, so as to complete the positioning of the extended beam assembly at the target position on the vehicle frame 3.
