Description

Technical Field

[0001] This utility model relates to the field of loaders, and more specifically, to a novel rear anti-collision device for loaders. Background Technology

[0002] In recent years, with the development of numerous infrastructure projects in my country, heavy-duty loaders have entered a golden age of development, with continuously increasing loading capacity and widespread application in large open-pit mines. However, due to the harsh operating environment, loaders are susceptible to rear-end collisions during reversing or operation. The upper rear section, particularly the engine or battery box, is particularly vulnerable to damage, potentially malfunctioning and severely impacting work efficiency. Therefore, appropriate protection for the upper rear section of the loader is essential. This new rear anti-collision device effectively prevents damage to the upper rear section of the loader, protecting the engine or battery box and improving the loader's working efficiency.

[0003] Currently, the rear of a loader typically consists of a counterweight or rear bumper, but there are usually no protective devices on top of it. During reversing or operation, the upper rear of the loader may collide with obstacles or vehicles, potentially damaging the engine or battery pack and rendering the loader unable to function properly. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a new rear anti-collision device for loaders, which aims to improve the problem that the upper rear of the loader may collide with obstacles or vehicles during reversing or working, which may damage the engine or battery box and prevent the loader from working properly.

[0005] This utility model is implemented as follows:

[0006] A novel rear anti-collision device for loaders includes an anti-collision component and a protective component.

[0007] The anti-collision assembly includes an anti-collision body, a right fixed frame, and a left fixed frame. The right fixed frame and the left fixed frame are fixedly connected to both ends of the anti-collision body, and an installation groove is formed between the right fixed frame and the left fixed frame. The protective assembly includes an anti-collision post and a wave energy-absorbing plate. The anti-collision post is fixedly connected to the upper side of the right fixed frame and the left fixed frame, and the wave energy-absorbing plate is disposed inside the anti-collision body.

[0008] In one specific implementation, the right fixing bracket and the left fixing bracket are provided with connecting bolts on their side walls.

[0009] In one specific implementation, the rear end of the anti-collision body is provided with a connecting groove, and the anti-collision body has a through-hole for inserting a pin. The pin hole passes through the connecting groove, and a hook pin is inserted into the pin hole.

[0010] In one specific implementation, the right fixing bracket includes a mounting shell and a first reinforcing plate, the first reinforcing plate being fixedly connected inside the mounting shell.

[0011] In one specific implementation, the left fixing frame and the right fixing frame have the same structure.

[0012] In one specific implementation, reinforcing ribs are provided between the inner sidewall of the mounting housing and the anti-collision body.

[0013] In one specific implementation, a second reinforcing plate is provided inside the anti-collision body near the lower side of the mounting groove.

[0014] In one specific implementation, the crash barrier includes a fixing plate, a pile body, and clamping bolts. The pile body is fixedly connected to the upper side of the fixing plate, and the fixing plate is clamped and fixed to the upper side of the right fixing frame and the left fixing frame by the clamping bolts.

[0015] In one specific implementation, a third reinforcing plate is provided between the fixing plate and the pile body.

[0016] In one specific implementation, the fixing plate has a fixing groove, and the clamping bolt can pass through one end of the fixing groove and the other end of the fixing groove.

[0017] The beneficial effects of this application are as follows: the right and left fixed frames and the wave energy-absorbing plate are welded to the anti-collision body to form a basic anti-collision body, which in turn forms a closed cavity that has both a certain strength and the ability to "absorb" energy. It can absorb most of the energy and play a good energy-absorbing protection role in the collision of the rear of the loader, minimizing the damage to the rear of the loader and reducing the damage to the rear frame of the loader. The anti-collision posts are installed on the left and right sides of the anti-collision body, which plays a protective role for the upper rear of the loader, protecting the rear hood and the engine or battery box inside from damage.

[0025] Example

[0026] Please see Figures 1 to 4 This utility model provides a novel rear anti-collision device for a loader, including an anti-collision component 100 and a protective component 200.

[0027] Please see Figure 2 The anti-collision assembly 100 includes an anti-collision body 110, a right fixing frame 120, and a left fixing frame 130. The right fixing frame 120 and the left fixing frame 130 are fixedly connected to both ends of the anti-collision body 110. A mounting groove 140 is formed between the right fixing frame 120 and the left fixing frame 130. Connecting bolts 150 are provided on the side walls of the right fixing frame 120 and the left fixing frame 130. The mounting groove 140 is inserted into the rear of the loader, and the right fixing frame 120 and the left fixing frame 130 are fixedly connected to the rear of the loader by the connecting bolts 150.

[0028] Please see Figure 3The protective component 200 includes anti-collision posts 210 and wave energy-absorbing plates 220. Anti-collision posts 210 are fixedly connected to the upper sides of the right fixed frame 120 and the left fixed frame 130, while wave energy-absorbing plates 220 are disposed inside the anti-collision body 110. The right fixed frame 120, the left fixed frame 130, and the wave energy-absorbing plates 220 are welded to the anti-collision body 110, forming a basic anti-collision structure, which in turn forms a closed cavity that has both sufficient strength and energy absorption capabilities. It can absorb most of the energy, providing excellent energy absorption protection in the event of a rear-end collision with the loader, minimizing damage to the rear of the loader and reducing damage to the loader's rear frame. The anti-collision posts 210 are installed on the left and right sides of the anti-collision body 110, protecting the upper rear of the loader and preventing damage to the rear hood and its internal engine or battery box. The rear end of the anti-collision body 110 is provided with a connecting groove 230, and a pin hole 240 is provided through the anti-collision body 110. The pin hole 240 passes through the connecting groove 230, and a hook pin (not shown in the figure) is inserted into the pin hole 240. When the loader needs to load, the connecting steel cable is passed into the connecting groove 230, and then the hook pin is inserted into the pin hole 240. The connecting steel cable is sleeved on the hook pin, and the connecting steel cable can be pulled by the hook pin to facilitate the loader's quick loading. The right fixing frame 120 includes a mounting shell 121 and a first reinforcing plate 122, and the first reinforcing plate 122 is fixedly connected to the inside of the mounting shell 121. The left fixing frame 130 has the same structure as the right fixing frame 120. A reinforcing rib 170 is provided between the inner wall of the mounting shell 121 and the anti-collision body 110. The first reinforcing plate 122 strengthens the overall strength of the mounting shell 121, and the reinforcing rib 170 strengthens the strength of the connection between the mounting shell 121 and the loader. A second reinforcing plate 160 is provided inside the anti-collision body 110 near the lower side of the mounting groove 140. The overall strength is enhanced by the second reinforcing plate 160, reducing the damage to the anti-collision body 110.

[0029] Please see Figure 4The crash barrier 210 includes a fixing plate 211, a pile body 212, and a clamping bolt 213. The pile body 212 is fixedly connected to the upper side of the fixing plate 211. The fixing plate 211 is clamped and fixed to the upper side of the right fixing frame 120 and the left fixing frame 130 by the clamping bolt 213. When the crash barrier 210 is damaged, the clamping bolt 213 is unscrewed to release the clamping bolt 213 from the fixing plate 211, and then the fixing plate 211 and the pile body 212 can be removed. A third reinforcing plate 214 is provided between the fixing plate 211 and the pile body 212. The third reinforcing plate 214 can strengthen the connection strength between the fixing plate 211 and the pile body 212. A fixing groove 215 is provided on the fixing plate 211, and the clamping bolt 213 can pass through one end of the fixing groove 215 and the other end of the fixing groove 215. When disassembling the anti-collision post 210, loosen the clamping bolt 213 to release the clamping bolt 213 from the fixing plate 211. The clamping bolt 213 slides along the fixing groove 215 until it slides to one end of the fixing groove 215. The fixing plate 211 is then pulled out along the fixing groove 215, allowing the clamping bolt 213 to leave the fixing plate 211. During the disassembly process, it is not necessary to completely remove the clamping bolt 213. Instead, the fixing plate 211 is installed, and the clamping bolt 213 clamps the other end of the fixing groove 215, thereby shortening the disassembly and installation time.

[0030] Specifically, the working principle of this new rear anti-collision device for the loader is as follows: The right fixed frame 120, the left fixed frame 130, and the wave energy-absorbing plate 220 are welded to the anti-collision body 110 to form a basic anti-collision structure, which in turn forms a closed cavity that has both a certain strength and the ability to absorb energy. It can absorb most of the energy, providing excellent energy-absorbing protection in the event of a collision with the rear of the loader, minimizing damage to the rear of the loader and reducing damage to the rear frame. Anti-collision posts 210 are installed on the left and right sides of the anti-collision body 110, protecting the upper rear of the loader and preventing damage to the rear hood and its internal engine or battery box.

[0031] When the loader needs to attach a load, the connecting steel cable is threaded into the connecting groove 230, and then the attach pin is inserted into the pin hole 240. The connecting steel cable is then looped onto the attach pin, and the connecting steel cable can be pulled by the attach pin, which facilitates the loader's quick attachment.

[0032] When disassembling the anti-collision post 210, loosen the clamping bolt 213 to release the clamping bolt 213 from the fixing plate 211. The clamping bolt 213 slides along the fixing groove 215 until it slides to one end of the fixing groove 215. The fixing plate 211 is then pulled out along the fixing groove 215, allowing the clamping bolt 213 to leave the fixing plate 211. During the disassembly process, it is not necessary to completely remove the clamping bolt 213. Instead, the fixing plate 211 is installed, and the clamping bolt 213 clamps the other end of the fixing groove 215, thereby shortening the disassembly and installation time.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
