Description

Technical Field

[0001] This utility model belongs to the technical field of dump truck body front panel, specifically relating to a dump truck body anti-collision buffer type front panel assembly. Background Technology

[0002] The front panel of a dump truck body is a key component for resisting material impact and ensuring the stability of the truck body structure. It must withstand the impact and compression of heavy objects such as stones and construction waste throughout the loading, transportation, and unloading process. To improve the front panel's anti-collision and cushioning capabilities, existing technologies often enhance its installation stability by adding fixing components. However, three major pain points remain: First, the clamping operation is cumbersome. Traditional fixing components require separate adjustment of the top and side clamping structures, a time-consuming and inefficient process. Second, clamping stability is insufficient. Asynchronous clamping of the top and side components can easily lead to force shifting, and some components may shift due to large clearances, causing the front panel to loosen and affecting its anti-collision effect.

[0003] With the increasing intensity of dump truck operations, traditional fixing components can no longer meet the requirements of "efficient clamping, stable fixing, and convenient maintenance." Therefore, developing a front panel assembly that can simultaneously clamp the top and sides, is easy to operate, and provides reliable fixing has become an urgent problem for the industry.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide a front panel assembly for anti-collision buffer of dump truck body to solve the problems of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A front panel assembly for anti-collision buffer of dump truck body includes a front steel plate assembly body. Two symmetrically arranged limiting components are installed on the front steel plate assembly body. The limiting components are used to press the front steel plate assembly body on the top and the sides.

[0007] Preferably, the limiting component includes a U-shaped sleeve that is movably sleeved on the outside of the front steel plate assembly body. Each side wall of the U-shaped sleeve is provided with a lifting channel with an I-shaped cross-section. Each of the two lifting channels has a slider with an I-shaped cross-section that slides in it. The same first pressure plate is fixed between the two sliders. The top ends of the lifting channels are all open to the outside. The bottom ends of the first pressure plates are used to press the top of the front steel plate assembly body.

[0008] Preferably, one of the sliders has a screw hole, which is threaded onto the outside of the screw rod. The bottom end of the screw rod is rotatably connected to the inner top wall of the lifting channel and extends to the bottom end of the screw rod, and is fixedly connected to a handle.

[0009] Preferably, each of the two sliders has a lifting rod fixedly connected to one end facing away from the other, and a transmission column is fixedly connected to both ends of the two lifting rods. A transmission rod with a Z-shaped vertical cross-section is movably sleeved on the outer side of each transmission column. A transmission channel that cooperates with the transmission column is opened on each transmission rod. The vertical cross-section of each transmission channel is Z-shaped, and the top end of the transmission channel is open to the outside.

[0010] Preferably, a movable column is fixedly connected to the bottom end of each of the two transmission rods on the same side, and a second pressure plate is fixedly connected to the end of each movable column facing the front steel plate assembly body. The second pressure plate presses against the side of the front steel plate assembly body. A limiting block is movably sleeved on the outer side of each movable column, and one end of each limiting block is fixedly connected to the outer side of the U-shaped sleeve. A synchronization plate is also fixedly connected between the two second pressure plates on the same side.

[0011] Preferably, the inner width of the transmission channel is equal to the diameter of the transmission column. This is to prevent the second pressure plate from shifting and causing unstable side clamping.

[0012] Compared with the prior art, the present invention has the following beneficial effects: (1) The front panel assembly of the dump truck body anti-collision buffer of this utility model, through the linkage structure of screw, slider and transmission rod, can drive the first pressure plate and the second pressure plate to press the front panel simultaneously by turning a single handle, without the need for step operation. Compared with the traditional step adjustment method, the pressing efficiency is greatly improved and the installation time is greatly shortened.

[0013] (2) The tops of the lifting channel and the transmission channel are both connected outwards, allowing for quick removal or assembly of components such as the first pressure plate and transmission rod from the U-shaped frame without disassembling the overall structure. During front panel maintenance, component disassembly and assembly are quick, significantly reducing labor and time costs. Attached Figure Description

[0018] See attached document Figure 1-3 A front panel assembly for anti-collision buffer of dump truck body includes a front steel plate assembly body 1. Two symmetrically arranged limiting components 2 are installed on the front steel plate assembly body 1. The limiting components 2 are used to press the front steel plate assembly body 1 on the top and on the sides.

[0019] Furthermore, such as Figure 1-3As shown, the limiting component 2 includes a U-shaped sleeve 21 movably fitted on the outside of the front steel plate assembly body 1. Both sides of the U-shaped sleeve 21 have I-shaped cross-section lifting channels. I-shaped sliders slide within each of the two lifting channels. A first pressure plate 22 is fixed between the two sliders. The top ends of the lifting channels are all outwardly connected. The bottom ends of the first pressure plates 22 are used to press against the top of the front steel plate assembly body 1. One slider has a screw hole threaded onto the outside of a screw rod 23. The bottom end of the screw rod 23 is rotatably connected to the inner top wall of the lifting channel and extends to the bottom end of the screw rod 23, where a handle is fixed. Lifting rods 24 are fixed to the opposite ends of the two sliders. Transmission columns 25 are fixed to both ends of the two lifting rods 24. The outer sides of the transmission columns 25 are movably fitted... A transmission rod 26 with a Z-shaped vertical cross-section is provided. Each transmission rod 26 has a transmission channel 27 that cooperates with the transmission column 25. The vertical cross-section of the transmission channel 27 is Z-shaped. The top of the transmission channel 27 is open to the outside. The bottom ends of the two transmission rods 26 on the same side are fixed to the moving column 28. The end of the moving column 28 facing the front steel plate assembly body 1 is fixed to the second pressure plate 29. The second pressure plate 29 presses against the side of the front steel plate assembly body 1. The outer side of the moving column 28 is movably fitted with a limiting block 211. One end of the limiting block 211 is fixed to the outer side of the U-shaped sleeve 21. A synchronization plate 210 is also fixed between the two second pressure plates 29 on the same side. The inner width of the transmission channel 27 is equal to the diameter of the transmission column 25. This is to prevent the second pressure plate 29 from moving and causing unstable side pressing.

[0020] The top ends of the lifting channel and the transmission channel 27 are both connected outwards, so that the first pressure plate 22 and the transmission column 25, which is fixed to both ends of the lifting rod 24 respectively, can be removed from the component, and the component can also be easily assembled onto the front steel plate assembly body 1.

[0021] In actual use, the U-shaped sleeve 21 is movably fitted onto the outside of the front steel plate assembly body 1, ensuring that the first pressure plate 22 is aligned with the top of the front plate and the second pressure plate 29 is aligned with the side of the front plate, and that each transmission component, including the transmission column 25, the transmission channel 27, and the moving column 28, is aligned and fitted.

[0022] Rotate the handle at the bottom of the screw 23. The screw 23 engages with the threaded hole on the slider. Since the slider is an I-shaped structure and is slidably connected in the I-shaped lifting channel, the screw 23 rotates and drives the slider to move vertically downward along the lifting channel.

[0023] During the downward movement of the slider, the first pressure plate 22 fixed between them moves downward synchronously until the bottom end of the first pressure plate 22 is tightly attached to the top of the front steel plate assembly body 1, thus completing the top clamping.

[0024] As the slider moves downwards, the lifting rods 24 fixed at both ends of the slider also move downwards simultaneously. The transmission columns 25 at both ends of the lifting rods 24 move downwards accordingly and slide within the transmission channel 27 of the Z-shaped transmission rod 26. Because the transmission channel 27 has a Z-shaped structure, the transmission columns 25 exert a lateral thrust on the inner wall of the transmission channel 27 when they move downwards. This drives the transmission rod 26 to move the second pressure plate 29 connected to the moving column 28 horizontally towards the front plate. This causes the second pressure plate 29 to simultaneously adhere to the side of the front steel plate assembly body 1, achieving lateral clamping. The second pressure plate 29 on the same side is connected by a synchronous plate 210 to ensure that the clamping force on both sides is consistent and to avoid force deviation.

[0025] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
