Description

Technical Field

[0001] This utility model relates to the field of mining machinery, and in particular to a hydraulic cylinder support for a dump truck, and a dump truck having the hydraulic cylinder support. Background Technology

[0002] The hydraulic cylinder support is a crucial component of the hydraulic system of a dump truck, typically mounted on the steering axle and connected to the hydraulic cylinder, cylinder beam, and hydraulic lines. Existing steering power cylinder support structures vary widely, usually consisting of welded parts, castings, or forgings. Castings and forgings are bulky, lack design flexibility, and their structures are not designed according to stress distribution. Therefore, existing dump truck hydraulic cylinder support structures often employ welded parts. However, welded parts are complex, have high manufacturing costs, and, due to their large size and space requirements, often demand higher precision in welding processes, leading to stress concentration and weld cracking, thus affecting the overall structural strength. To address these technical problems, the purpose of this invention is to provide a new hydraulic cylinder support structure. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a cylinder support for a dump truck and a dump truck, which can reduce stress concentration at the edge welding and improve the material utilization rate of the support.

[0004] One embodiment of this utility model provides a cylinder support for a dump truck, comprising two main support plates for connecting to the steering axle of the dump truck and at least two support ribs connected between the two main support plates. Each main support plate includes a main body, a first connecting portion and a second connecting portion formed at opposite ends of the main body, a first bent portion formed at the end of the first connecting portion, and a second bent portion formed at the end of the second connecting portion. The first bent portions of the two main support plates are bent relative to each other, and the second bent portions of the two main support plates are bent relative to each other. The width of the first connecting portion gradually decreases from one side of the main body to the side of the first bent portion, and the width of the second connecting portion gradually decreases from one side of the main body to the side of the second bent portion.

[0005] Furthermore, the width of the first bend and the second bend on the side closer to the main body is greater than the width on the side farther from the main body.

[0006] Furthermore, the main body is provided with a first mounting hole for connecting with the suspension cylinder, and the first mounting hole is located near the first bend.

[0007] Furthermore, a second mounting hole for connecting with the tie rod is provided on the main body. The second mounting hole is located near the second bend, and the diameter of the first mounting hole is larger than that of the second mounting hole.

[0008] Furthermore, the support main board also includes a first connecting ring protruding around the first mounting hole and a second connecting ring protruding around the second mounting hole.

[0009] Furthermore, there are two support stiffeners. One of them is connected on both sides between the first and second mounting holes of each of the two main support plates, and the other is connected on both sides between the second mounting hole and the second bend of each of the two main support plates.

[0010] Furthermore, the cylinder support also includes two mounting bases, each welded to the outside of one of the main support plates. One mounting base is located next to the first connecting ring, and the other is located next to the second connecting ring on the same side as the first plate.

[0011] Another embodiment of this utility model provides a dump truck, including the above-mentioned cylinder support and suspension cylinder. The suspension cylinder includes a cylinder pin, which passes through a first mounting hole and a first connecting ring and is connected to the main board of the support.

[0012] Furthermore, the dump truck also includes a tie rod with a tie rod pin that passes through a second mounting hole and a second connecting ring and is connected to the support main plate.

[0013] Furthermore, the dump truck also includes a steering axle, with the main support plate of the hydraulic cylinder support welded to the steering axle.

[0014] This utility model provides a cylinder support for a dump truck and a dump truck in general. The cylinder support includes two main support plates and at least two support stiffeners. Each main support plate includes a body portion, a first connecting portion, a second connecting portion, a first bending portion, and a second bending portion. By incorporating the support stiffeners, the cylinder support achieves higher bending strength, better material distribution, reduced load distribution, and improved connection strength. The first and second bending portions of the two main support plates are bent relative to each other. This design reduces the impact of stress during edge welding and improves welding strength. The width of both the first and second connecting portions gradually decreases from one side of the body portion outwards. The curved design of the connecting portions ensures the overall structural continuity, and the main support plates are locally thinned, reducing their weight and overall the weight of the cylinder support. This achieves improved material utilization while maintaining the rigidity of the cylinder support. Attached Figure Description

Detailed Implementation

[0021] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0022] like Figures 1 to 3 As shown, one embodiment of this application provides a cylinder support 1 for a dump truck, including two support main plates 10 and at least two support stiffeners 11 connected between the two support main plates 10.

[0023] The support plate 10 is used to connect with the steering axle 2 of the dump truck. Each support plate 10 includes a main body 100, a first connecting part 101 and a second connecting part 102, a first bending part 103, and a second bending part 104. The first connecting part 101 and the second connecting part 102 are formed at opposite ends of the main body 100, the first bending part 103 is formed at the end of the first connecting part 101, and the second bending part 104 is formed at the end of the second connecting part 102. The width of the first connecting part 101 gradually decreases from the side near the main body 100 to the side near the first bending part 103. Similarly, the width of the second connecting part 102 gradually decreases from the side near the main body 100 to the side near the second bending part 104. By designing the first connecting part 101 and the second connecting part 102 as smooth, outwardly arched connecting curves, and based on the maximum load-bearing capacity of the support plate 10, the overall structural continuity is ensured and the material utilization rate is improved. The first bending portion 103 of the two support main plates 10 is bent inward relative to the main body 100, and the second bending portion 104 of the two support main plates 10 is bent inward relative to the main body 100. Furthermore, the width of the first bending portion 103 and the second bending portion 104 on the side closer to the main body 100 is greater than the width on the side farther from the main body 100. By bending both ends of the support main plates 10 to form the first bending portion 103 and the second bending portion 104, the support main plates 10 are locally thinned, thereby reducing their weight and consequently reducing the overall weight of the cylinder support 1. This achieves a reduction in the weight of the cylinder support while maintaining its rigidity, thus improving the material utilization rate of the cylinder support. On the other hand, the design of the first bending portion 103 and the second bending portion 104 can reduce the influence of stress during edge welding and improve welding strength. In a further embodiment, at least one of the first bending portion 103, the second bending portion 104, the first connecting portion 101, and the second connecting portion 102 can be designed to reduce the wall thickness, thereby further improving the material utilization rate of the cylinder support.

[0024] The support main plate 10 also includes a first mounting hole 105 and a second mounting hole 106 formed on the main body 100. The first mounting hole 105 is used to connect with the suspension cylinder of the dump truck and is located near the first bend 103. The second mounting hole 106 is used to connect with the crossbar of the dump truck and is located near the second bend 104. Meanwhile, since the diameter of the cylinder pin 31 of the suspension cylinder is larger than the diameter of the tie rod pin 41 of the crossbar, the diameter of the first mounting hole 105 is larger than the diameter of the second mounting hole 106 to accommodate the installation of different pins.

[0025] The support main board 10 also includes a first connecting ring 107 and a second connecting ring 108. Multiple first connecting rings 107 are used to be sleeved on the cylinder pin 31 of the suspension cylinder and protrude around both sides of the first mounting hole 105. Multiple second connecting rings 108 are used to be sleeved on the tie rod pin 41 of the tie rod and protrude around both sides of the second mounting hole 106.

[0026] The support main board 10 also includes two mounting bases 109, both of which are welded to one side of one of the support main boards 10. One of them is located next to the first connecting ring 107 and is used to lock the cylinder pin 31 of the suspension cylinder; the other is located next to the second connecting ring 108 and is used to lock the tie rod pin 41 of the tie rod.

[0027] The hydraulic cylinder support 1 also includes at least two support stiffeners 11, which are connected between two main support plates 10. Further, there are two support stiffeners 11. One stiffener is connected on both sides between the first mounting hole 105 and the second mounting hole 106 of each of the two main support plates 10; the other stiffener is connected on both sides between the second mounting hole 106 and the second bending portion 104 of each of the two main support plates 10. The two stiffeners 11 are positioned differently to adapt to the stress conditions of the hydraulic cylinder support, thereby better strengthening the connection strength between the two main support plates 10. By connecting the main support plates 10 of the two hydraulic cylinder supports 1 with two support stiffeners 11, the top view of the hydraulic cylinder support 1 is I-shaped. Compared with traditional support structures, this design has higher bending strength in the stress direction of the support, better material distribution, increased material utilization, reduced load distribution, and improved connection strength.

[0028] In summary, the above-described embodiments of this utility model provide a hydraulic cylinder support for a dump truck, comprising two main support plates 10 and at least two support ribs 11. Each main support plate 10 includes a main body 100, a first connecting portion 101, a second connecting portion 102, a first bending portion 103, and a second bending portion 104. By providing the support ribs 11, the hydraulic cylinder support 1 has higher bending strength, better material distribution, reduced load distribution, and improved connection strength. The first bending portions 103 of the two main support plates 10 are bent inward relative to the main body 100, and the second bending portions 104 of the two main support plates 10 are bent inward relative to the main body 100. By designing the first bending portions 103 and the second bending portions 104, the influence of stress during edge welding can be reduced, and the welding strength can be improved. The width of the first connecting portion 101 gradually decreases from one side of the main body 100 outwards, and the width of the second connecting portion 102 also gradually decreases from one side of the main body 100 outwards. Furthermore, the width change of the first connecting portion 101 is less than the width change of the second connecting portion 102. This curved design of the connecting portions ensures the overall structural continuity and improves material utilization. On the other hand, by simultaneously optimizing the design of the bending portion and the connecting portion, the main support plate 10 is locally thinned, reducing its weight and consequently reducing the overall weight of the cylinder support 1. This achieves a reduction in the weight of the cylinder support while maintaining its rigidity, and also improves the material utilization of the cylinder support 1.

[0029] like Figure 3 and Figure 4 As shown, another embodiment of this utility model provides a dump truck, including the aforementioned cylinder support 1 and suspension cylinder. The suspension cylinder includes a cylinder pin 31, which passes through a first mounting hole 105 and a first connecting ring 107 to connect to the support main plate 10 and is locked by a mounting seat 109 next to the first connecting ring 107, thereby connecting the steering axle 2 to the suspension cylinder. The dump truck also includes a tie rod and the steering axle 2. The tie rod has a tie rod pin 41, which passes through a second mounting hole 106 and a second connecting ring 108 to connect to the support main plate 10 and is locked by a mounting seat 109 next to the second connecting ring 108, thereby connecting the steering axle 2 to the tie rod. The support main plate 10 of the cylinder support 1 is welded to the steering axle 2 to connect the steering axle 2 and the cylinder support 1 into a single unit. By optimizing the design of the bending and connecting parts of the cylinder support 1, on the one hand, the stress concentration of the cylinder support 1 is reduced, the risk of weld cracking is lowered, and the service life of the dump truck is improved; on the other hand, while ensuring the rigidity of the cylinder support 1, the weight of the cylinder support 1 is reduced, thereby improving the material utilization rate of the cylinder support 1 and reducing the production cost of the dump truck.

[0030] In summary, another embodiment of this utility model provides a dump truck, including the aforementioned cylinder support 1, suspension cylinder, tie rod, and steering axle 2. The cylinder pin 31 of the suspension cylinder is connected to the support main plate 10 through a first mounting hole 105 and a first connecting ring 107; the tie rod pin 41 of the tie rod is connected to the support main plate 10 through a second mounting hole 106 and a second connecting ring 108; the support main plate 10 of the cylinder support 1 is welded to the steering axle 2. Multiple support stiffeners 11 are provided on the cylinder support 1, which can significantly improve the strength of the cylinder support 1 and reduce stress concentration. Simultaneously, by optimizing the design of the bending and connecting parts of the cylinder support 1, stress concentration in the cylinder support 1 is further reduced, the risk of weld cracking is lowered, and the weight of the cylinder support 1 is reduced while ensuring its rigidity, thus improving the material utilization rate of the cylinder support 1, thereby increasing the service life of the dump truck and reducing its production cost.

[0031] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
