Description

Technical Field

[0001] This utility model relates to the field of assembly technology, and more specifically, to a cargo box tilting pin mounting device. Furthermore, it also relates to a dump truck including the aforementioned cargo box tilting pin mounting device. Background Technology

[0002] In existing technology, a dump truck is a specialized vehicle that uses its chassis to drive a hydraulic lifting mechanism to tilt its cargo box at a certain angle for unloading, and then relies on the weight of the cargo box to return it to its original position. Common dump trucks typically consist of a chassis, cargo box assembly, subframe, hydraulic lifting mechanism, and power take-off (PTO). The subframe is one of the main working components of the dump truck, connected to the chassis beam via U-bolts. The cargo box assembly, consisting of the front door, side door panels, floor, and rear door, is the material loading device, connected to the subframe via a tilting pin. Therefore, the tilting pin is a component used to connect the cargo box assembly and the subframe, enabling their connection and installation.

[0003] The common tipping pin mounting device for dump truck cargo boxes usually involves machining a groove on the tipping pin, and connecting the baffle to the tipping support with mounting bolts. The baffle is only mounted on one side of the tipping pin, and two mounting bolts are used to connect the baffle and the tipping support, resulting in a small number of mounting bolts. During use, the cargo box assembly is frequently tipped over, which can easily lead to the mounting bolts being cut off.

[0004] In summary, how to connect the dump truck cargo box assembly and the subframe while preventing the pins from rotating and axially moving during the cargo box assembly's tipping process is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a cargo box tilting pin installation device, which can connect the dump truck cargo box assembly and the subframe, and also prevent the pin from rotating and axially moving during the tilting process of the cargo box assembly.

[0006] Another objective of this invention is to provide a dump truck that includes the aforementioned cargo box tipping pin mounting device.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A cargo box tilting pin mounting device includes:

[0009] A flip pin has flat portions at both ends, and the flat portions and the outer periphery of the flip pin cooperate to form a stepped surface.

[0010] A baffle is provided with an opening that engages with the flat portion. The side of the baffle abuts against the stepped surface. The baffle is provided with a mounting hole and a locking member provided in the mounting hole. The locking member is used to lock the baffle and the flip support.

[0011] In one embodiment, the flat portion is provided only at the upper part of one end of the flip pin, and the flat portion is provided only at the lower part of the other end of the flip pin.

[0012] In one embodiment, the flat portion is provided at both the upper and lower parts of the two ends of the flip pin.

[0013] In one embodiment, the baffle is provided with at least three mounting holes and the locking element at equal intervals along the circumference.

[0014] In one embodiment, the baffle comprises a steel plate.

[0015] In one embodiment, the locking element includes a bolt.

[0016] A dump truck includes the cargo box tipping pin mounting device described in any of the above claims.

[0017] In one embodiment, the system further includes a subframe system and a cargo box assembly, the cargo box assembly being connected to the subframe system via a tilt pin of the cargo box tilt pin mounting device, and the baffle of the cargo box tilt pin mounting device being mounted on the tilt support of the cargo box assembly via a locking member.

[0018] In one embodiment, the dimensions of the flat portion of the flip pin match the width of the flip support, and the flanges at both ends of the flip support are provided with threaded holes. The threaded holes are correspondingly provided with the mounting holes of the cargo box flip pin mounting device to cooperate in installing the locking component.

[0019] When using the cargo box tilting pin installation device provided by this utility model, both ends of the tilting pin are provided with flat portions (for example, the flat portions can be obtained by milling the tilting pin). The opening of the baffle and the flat portion of the tilting pin are engaged and fixed, restricting the rotation of the tilting pin. In addition, the side of the baffle abuts against the stepped surface, and the baffle is connected to the tilting support. The axial position of the tilting pin is effectively limited by the baffles at both ends of the tilting pin, preventing axial movement of the tilting pin. In addition, the baffles at both ends of each tilting pin are connected and fixed to the corresponding tilting support by multiple locking parts, which effectively improves the shear resistance of the tilting pin and helps to solve the problem that the locking parts are easily cut off due to frequent tilting of the cargo box assembly.

[0020] In summary, the cargo box tilting pin mounting device provided by this utility model can connect the dump truck cargo box assembly and the subframe, and can also prevent the pin from rotating and moving axially during the tilting process of the cargo box assembly.

[0021] In addition, this utility model also provides a dump truck including the above-mentioned cargo box tipping pin mounting device. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] The core of this utility model is to provide a cargo box tilting pin mounting device, which can connect the dump truck cargo box assembly and the subframe, and also prevent the pin from rotating and axially moving during the tilting process of the cargo box assembly. Another core aspect of this utility model is to provide a dump truck including the above-mentioned cargo box tilting pin mounting device.

[0034] Please refer to Figure 6 and Figure 7 This specific embodiment provides a cargo box tilting pin mounting device, including:

[0035] The flip pin 1 has flat portions 11 at both ends, and the flat portions 11 and the outer periphery of the flip pin 1 cooperate to form a stepped surface 12.

[0036] The baffle 2 has an opening 21 that engages with the flat portion 11. The side of the baffle 2 abuts against the stepped surface 12. The baffle 2 has a mounting hole 22 and a locking member 3 located in the mounting hole 22. The locking member 3 is used to lock the baffle 2 and the flip support 4.

[0037] It should be noted that both ends of the flip pin 1 are provided with flat portions 11, which means that both ends of the flip pin 1 are milled flat. Milling flattening refers to milling the workpiece at a predetermined position in machining to form a flat shape. This machining method is usually used for shaft products to create a specific flat position on the workpiece for subsequent assembly or use. Moreover, the milling flattening dimension of the flip pin 1 matches the width of the flip support 4 so that the opening 21 of the baffle 2 engages with the flat portion 11. Furthermore, the flanges at both ends of the flip support 4 are machined with threaded holes, and the baffle 2 is provided with mounting holes 22 and locking members 3 located in the mounting holes 22. The locking members 3 can pass through the mounting holes 22 and the threaded holes to tighten the baffle 2 and the flip support 4, thereby preventing axial movement and rotation of the flip pin 1 and realizing the installation and positioning of the flip pin 1.

[0038] In practical applications, the shape, structure, size, material, and position of the flip pin 1 and the baffle 2 can be determined according to the actual situation and needs.

[0039] When using the cargo box tilting pin installation device provided by this utility model, both ends of the tilting pin 1 are provided with flat portions 11 (for example, the flat portions 11 can be obtained by milling the tilting pin 1). The opening 21 of the baffle 2 is engaged and fixed with the flat portions 11 of the tilting pin 1, restricting the rotation of the tilting pin 1. Furthermore, the side of the baffle 2 abuts against the stepped surface 12, and the baffle 2 is connected to the tilting support 4, so as to effectively limit the axial position of the tilting pin 1 by the baffles 2 at both ends of the tilting pin 1, and prevent the tilting pin 1 from axially moving. In addition, the baffles 2 at both ends of each tilting pin 1 and the corresponding tilting support 4 are connected and fixed by multiple locking parts 3, which effectively improves the shear resistance of the tilting pin 1 and helps to solve the problem that the locking parts 3 are easily cut off due to the frequent tilting of the cargo box assembly.

[0040] In summary, the cargo box tilting pin mounting device provided by this utility model can connect the dump truck cargo box assembly and the subframe, and can also prevent the pin from rotating and moving axially during the tilting process of the cargo box assembly.

[0041] In one embodiment, one end of the flip pin 1 has a flat portion 11 only at the upper part, and the other end of the flip pin 1 has a flat portion 11 only at the lower part. The shape of the opening 21 of the baffle 2 matches the shape of the flat portion 11. Based on this, one of the upper or lower parts of the opening 21 of the baffle 2 can be set as a straight section, and the other as an arc-shaped section matching the flip pin 1. Furthermore, baffles 2 are installed on both sides of the flip pin 1, and each baffle 2 on one side is connected to the flip bracket by at least two bolts.

[0042] In one embodiment, such as Figures 4 to 7 As shown, both the upper and lower parts of the flip pin 1 are provided with flat parts 11, that is, the upper and lower parts of both ends of the flip pin 1 can be milled flat, so that both the upper and lower parts of both ends of the flip pin 1 are provided with flat parts 11. Based on this, the upper and lower parts of the opening 21 of the baffle 2 can be set as straight sections to ensure the snap-fit ​​and fixing effect between the baffle 2 and the flip pin 1, and the baffle 2 is used to limit the axial movement of the flip pin 1.

[0043] In one embodiment, such as Figure 2 As shown, the baffle 2 has at least three mounting holes 22 and locking elements 3 evenly spaced along the circumference. The baffles 2 on both sides of the flip pin 1 effectively restrict the axial movement of the flip pin 1. Furthermore, the flattened portion 11 of the flip pin 1, after milling, is engaged and fixed with the baffle 2 to effectively limit the rotation of the flip pin 1, thereby achieving the installation and positioning of the flip pin 1. Each baffle can be provided with four mounting holes 22 and locking elements 3, and each flip pin 1 is installed using a total of eight locking elements 3 (bolts), improving the shear resistance of the flip pin 1 and solving the problem of bolts being easily cut off.

[0044] In one embodiment, the baffle 2 includes a steel plate, which has excellent mechanical properties and can withstand heavy loads and impacts. Using a steel plate to make the baffle 2 helps to improve the performance and service life of the baffle 2.

[0045] In one embodiment, the locking element 3 includes a bolt.

[0046] It should be noted that the opening 21 of the baffle 2 can be inserted into the flat part 11 of the flip pin 1, so that the side of the baffle 2 abuts against the stepped surface 12, that is, the baffle 2 and the end of the flip pin 1 are locked together to restrict the rotation of the flip pin 1. The baffles 2 at both ends of the flip pin 1 can effectively limit the axial position of the flip pin 1 and prevent the flip pin 1 from moving axially. In addition, the baffle 2 and the flip support 4 are fixedly connected by bolts, and the baffle 2 at both ends of each flip pin 1 and the corresponding flip support 4 are fixed by multiple bolts, which effectively improves the shear resistance of the flip pin 1 and helps to solve the problem that the bolts are easily cut off due to the frequent flipping of the cargo box assembly. For example, baffles 2 can be installed on both sides of the flip pin 1. Each baffle 2 on one side is provided with four mounting holes 22 and four locking parts 3 (bolts), so there are a total of 4 bolts at both ends of the flip pin 1, which can improve the shear resistance of the flip pin 1. This device is feasible and reliable, and can solve the problem that the bolts of the existing dump truck cargo box tipping pin 1 are easily cut off.

[0047] In addition to the cargo box tipping pin mounting device mentioned above, this utility model also provides a dump truck that includes the cargo box tipping pin mounting device disclosed in the above embodiments. For the structure of other parts of the dump truck, please refer to the prior art, which will not be repeated here.

[0048] In one embodiment, the system further includes a subframe system and a cargo box assembly. The cargo box assembly is connected to the subframe system via a tilt pin 1 of a cargo box tilt pin mounting device. The baffle 2 of the cargo box tilt pin mounting device is mounted on the tilt support 4 of the cargo box assembly via a locking member 3. The baffles 2 at both ends of the tilt pin 1 can effectively limit the axial position of the tilt pin 1 and prevent the tilt pin 1 from moving axially.

[0049] In one embodiment, the dimensions of the flat portion 11 of the flip pin 1 match the width of the flip support 4. The flanges at both ends of the flip support 4 are provided with threaded holes, which correspond to the mounting holes 22 of the cargo box flip pin mounting device, to facilitate the installation of the locking element 3. Specifically, each flip pin 1 has a baffle 2 snapped onto its flat portion 11 at both ends. The baffle 2 and the corresponding flip support 4 are connected and fixed by multiple bolts, effectively improving the shear resistance of the flip pin 1 and solving the problem of bolts being easily cut off due to frequent flipping of the cargo box assembly.
