Description

Technical Field

[0001] This utility model relates to the field of dump truck technology, and in particular to a reinforced semi-trailer rear-tipping dump truck body. Background Technology

[0002] Dump trucks are vehicles that unload goods by themselves through hydraulic or mechanical lifting. They are also called tipper trucks and consist of a truck chassis, hydraulic lifting mechanism, cargo box and power take-off device. Dump truck cargo boxes are divided into rear-tilting and side-tilting types. The movement of piston rods is controlled by the operating system. Rear-tilting is more common. Pushing the piston rod causes the cargo box to tip over.

[0003] Chinese Patent CN203580733U discloses a reinforced semi-trailer rear-tipping dump truck body, including an auxiliary frame fixed to the bottom plate of the body, and a main frame whose end is hinged to the end of the auxiliary frame via a pin. The auxiliary frame and the main frame are generally shaped like a gooseneck. Unlike the prior art, the auxiliary frame includes several auxiliary longitudinal beams and several auxiliary cross beams, which are welded together with the auxiliary longitudinal beams. The auxiliary cross beams located at the rear of the auxiliary frame are continuous, and the auxiliary longitudinal beams are spaced apart between the auxiliary cross beams. Although the amplitude of the vibration caused by the left and right bumps of the truck body is the largest at the rear edge of the auxiliary frame, and the resulting impact force acts on both ends of the cross beams, since the auxiliary cross beams are continuous and there are no welds, the entire impact force is evenly distributed across the entire auxiliary cross beam, making it less likely for the weld to reach the fatigue limit and break. This solves a long-standing problem in the field.

[0004] However, the above technical solution has the following shortcomings: The tail door of the carriage is the same as that of a traditional semi-trailer carriage. The tail door is connected to the carriage through a hinge shaft at the top, and the opening and closing range is fixed by a limiting chain at the bottom. However, the chain is essentially a rigid constraint device, which only limits the maximum opening and closing angle by a fixed length and cannot achieve dynamic adjustment. When transporting sticky and wet materials, the preset opening is insufficient, which leads to unloading blockage. When transporting loose materials, the opening is too large, which causes impact and spillage, affecting the unloading effect. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a reinforced semi-trailer rear-tipping dump truck body, which can select the tilting angle of the tailgate according to the characteristics of the material, ensuring safety and smoothness during unloading and optimizing the unloading effect.

[0006] The technical solution of this utility model is a reinforced semi-trailer rear-tipping dump truck body, including a frame and a tipping mechanism; the truck body is rotatably connected to the frame, and a tailgate is provided at the rear of the truck body; the frame and the truck body are provided with a tipping mechanism; the tipping mechanism includes two horizontally distributed second hydraulic cylinders, a connecting plate provided at the end of the piston rod of the second hydraulic cylinders, a fixing frame provided on the connecting plate, a first hinge member provided on the fixing frame, a second hinge member rotatably connected to the first hinge member and having a bent portion, a push block provided on the second hinge member, two guide frames provided on the truck body, and rollers rotatably connected to the push blocks; the push blocks are slidably disposed inside the guide frames, and the rollers and guide frames are rolledly connected.

[0007] Preferably, the tailgate is provided with two rotating arms, and the main body of the carriage is provided with two first connecting seats, and the rotating arms and the first connecting seats are rotatably connected.

[0008] Preferably, the main body of the carriage is provided with two supports, and the second hydraulic cylinder is provided on the supports.

[0009] Preferably, the rear tipping mechanism includes a second connecting seat disposed on the main body of the carriage, a first mounting ring rotatably connected to the second connecting seat, a first hydraulic cylinder disposed on the first mounting ring, a fixed frame disposed on the frame, and a second mounting ring rotatably connected to the fixed frame; the end of the first hydraulic cylinder is disposed on the second mounting ring.

[0010] Preferably, the main body of the carriage is provided with a safety reinforcement component, which includes two support blocks on the tailgate, an insert block on the support blocks, a docking block on the main body of the carriage, and an insert rod passing through the docking block and the insert block.

[0011] Preferably, a disc is provided on the insertion rod, and a handle is provided on the disc.

[0012] Preferably, a first magnet is provided on the docking block, and a second magnet is provided on the disk, with the first magnet and the second magnet being magnetically connected.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects: This utility model, through its specially designed flipping mechanism, can not only control the opening and closing of the tailgate, but also control the rotation angle when the tailgate is opened. This allows for the selection of the tailgate flipping angle based on the characteristics of the material, ensuring safety and smoothness during unloading. It avoids the problems of unloading blockage or impact spillage caused by traditional limit chains, optimizes the unloading effect, and has good practicality. Attached Figure Description

[0015] Example 1: As Figure 1 - Figure 3 As shown in the figure, this embodiment proposes a reinforced semi-trailer rear-tipping dump truck body, including a frame 1 and a tipping mechanism; a truck body 2 is rotatably connected to the frame 1, a tailgate 3 is provided at the rear of the truck body 2, two rotating arms 4 are provided on the tailgate 3, two first connecting seats 5 are provided on the truck body 2, the rotating arms 4 and the first connecting seats 5 are rotatably connected, a tipping mechanism is provided on the frame 1 and the truck body 2, the tipping mechanism includes a second connecting seat 6 provided on the truck body 2, a first mounting ring 7 rotatably connected to the second connecting seat 6, a first hydraulic cylinder 8 provided on the first mounting ring 7, a fixing frame 9 provided on the frame 1, and a second mounting ring 10 rotatably connected to the fixing frame 9; the end of the first hydraulic cylinder 8 is provided on the second mounting ring 10.

[0016] The tilting mechanism includes two horizontally distributed second hydraulic cylinders 12, a connecting plate 13 disposed at the piston rod end of the second hydraulic cylinder 12, a fixing frame 14 disposed on the connecting plate 13, a first hinge 15 disposed on the fixing frame 14, a second hinge 16 rotatably connected to the first hinge 15 and having a bent portion, a push block 17 disposed on the second hinge 16, two guide frames 18 disposed on the main body 2 of the carriage, and rollers 19 rotatably connected to the push block 17; the push block 17 is slidably disposed inside the guide frame 18, the rollers 19 and the guide frame 18 are rotatably connected, and two supports 11 are disposed on the main body 2 of the carriage, and the second hydraulic cylinders 12 are disposed on the supports 11.

[0017] In this embodiment, when it is necessary to unload the goods inside the main body 2 of the carriage, the first hydraulic cylinder 8 is activated to drive the piston rod on it to extend. This, in conjunction with the first mounting ring 7 rotatably mounted on the second connecting seat 6 and the second mounting ring 10 rotatably mounted on the fixed frame 9, allows the first hydraulic cylinder 8 to adapt to the backward tilting angle of the main body 2 of the carriage while driving the piston rod to extend, thus deflecting at a certain angle until the main body 2 of the carriage rotates to the selected control angle and then stops. Next, the second hydraulic cylinder 12 is activated to drive the connecting plate 13 to move linearly along the axial direction of the piston rod. The connecting plate 13 then pushes the fixed frame 14 to move, using thrust to... The first hinge 15 and the second hinge 16 rotate relative to each other, and the thrust is transmitted to the push block 17. The push block 17 then pushes the tailgate 3 to rotate around the pivot of the first connecting seat 5 and the rotating arm 4. The roller 19 reduces the friction between the push block 17 and the guide frame 18. The angle of rotation of the tailgate 3 is selected according to the characteristics of the material to ensure safety and smoothness during unloading. This avoids the problems of unloading blockage or impact spillage caused by traditional limit chains, optimizes the unloading effect, and has good practicality. The fixed frame 14 can be equipped with a slider guide rail to reduce the radial wear of the cylinder through the guiding effect.

[0018] It should be noted that: the support 11 is made of steel plate containing Mn forging to ensure structural strength, and the second hydraulic cylinder 12 needs to be equipped with a side protective net (not shown) on its outside when in use, and the surface is sprayed with polyurea elastic to provide good protection for the cylinder body. The installation design needs to take into account the volume and shape of the main body 2 of the carriage to reduce the impact on the overall streamline shape of the vehicle. When the width of the main body 2 of the carriage is greater than 2.4m, two first hydraulic cylinders 8 need to be installed, and synchronization and anti-balance technology is adopted to ensure safety.

[0019] Example 2: Figure 3 As shown, this embodiment proposes a reinforced semi-trailer rear-tipping dump truck body. Compared with the first embodiment, in this embodiment, the main body 2 of the truck body is equipped with a safety reinforcement component. The safety reinforcement component includes two support blocks 20 set on the tailgate 3, an insert block 22 set on the support blocks 20, a docking block 21 set on the main body 2 of the truck body, and an insert rod 24 passing through the docking block 21 and the insert block 22. A disc 23 is set on the insert rod 24, and a handle 25 is set on the disc 23.

[0020] In this embodiment, when the semi-trailer closes the tailgate 3 before transferring goods, the insert 22 on the support block 20 will be inserted into the interior of the docking block 21. Then, the handle 25 will insert the insert rod 24 into the interior of the docking block 21 and through the insert 22 to restrict the insert 22, thereby reinforcing and stabilizing the tailgate 3 and ensuring the rigid requirement of transportation safety.

[0021] Example 3: Figure 4 As shown in the figure, the reinforced semi-trailer rear-tipping dump truck body proposed in this embodiment, compared with the second embodiment, has a first magnet 26 provided on the docking block 21 and a second magnet 27 provided on the disc 23, and the first magnet 26 and the second magnet 27 are magnetically connected.

[0022] In this embodiment, when the insertion rod 24 is inserted into the interior of the docking block 21 and the disk 23 is attached to the docking block 21, the first magnet 26 and the second magnet 27 on the docking block 21 and the disk 23 have a magnetic attraction effect, which stabilizes the insertion rod 24 and prevents it from falling off due to normal vibration. In addition, the surface structure of the insertion rod 24 is made of a material with a certain degree of elasticity to fill the gap.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
