Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery equipment, in particular to a reinforced loader front frame wing box. Background Art

[0002] The front frame assembly of the loader is a major component of the loader, which bears important functions such as connecting the front axle, engine and operating platform of the loader. The front frame assembly is usually welded from a variety of metal plates and has sufficient strength and rigidity to withstand various loads generated during the working process.

[0003] In the prior art, in the front frame assembly, the left and right wing boxes are located on both sides of the front frame for installing components such as steering cylinders and suspension systems. During the loader trial, concrete blocks are prone to fall, especially when the loader with a bucket moves construction waste. The concrete blocks are not only easy to damage the cylinder, suspension system components and oil pipelines, but also bounce off again after hitting the wing box, which is easy to cause damage to other parts of the loader or nearby equipment and workers. For this reason, we propose a reinforced loader front frame wing box to solve the above problems. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model, by setting a wing box assembly, adopts a coaming plate, a side plate and a cover plate to form a wing box structure, which can protect the parts in the wing box, and can also use the detachable side plate to facilitate users to maintain and replace the parts. By setting a rubber suction cup with a compression spring, after a concrete block or other object hits the cover plate, the cover plate rotates and absorbs the impact force, and then the rubber suction cup is sucked on the connecting plate without directly rebounding, which can effectively reduce the rebound of the cover plate after buffering, and avoid the concrete from bouncing off and causing damage to other parts of the loader or nearby equipment and workers;

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 , a reinforced loader front frame wing box, comprising a front frame assembly body 1, both sides of the front frame assembly body 1 are provided with wing box components;

[0023] The wing box assembly includes a panel 2 fixedly connected to the front frame assembly body 1, a vertical slot 3 is provided on the panel 2, and a side panel 4 is inserted in the vertical slot 3, wherein the panel 2 is C-shaped, and the side panel 4 and the panel 2 are inserted to form a rectangular frame, and a plurality of cross panels 5 are also fixedly connected to the side panel 4, and a cover plate 6 is rotatably connected to the upper end of the panel 2, a sleeve 7 is fixedly connected to the inner wall of the panel 2 close to the cover plate 6, and a push rod 8 is slidably connected in the sleeve 7, and the push rod 8 is arranged to abut against the cover plate 6, a compression spring 9 is fixedly connected in the sleeve 7, and the upper end of the compression spring 9 is arranged to abut against the push rod 8, and a rubber suction cup 10 is provided at the lower end of the push rod 8, and a connecting plate 11 cooperating with the rubber suction cup 10 is provided at the lower end of the sleeve 7, and microholes are provided on the connecting plate 11;

[0024] In this design, the enclosure 2 and the side panels 4 are combined to form the main part of the wing box assembly, and the cover plate 6 protects the upper opening of the main part, while the lower end does not need to be surrounded and protected. Since the enclosure 2 and the side panels 4 are not integral, a cross plate 5 is provided to abut against the enclosure 2 and the front frame assembly body 1, so as to further support the enclosure 2 and improve the physical strength of the entire wing box structure. In addition, this design is also convenient for users to replace and maintain the parts in the wing box assembly;

[0025] When a concrete block falls, once the concrete block hits the cover plate 6, the cover plate 6 will rotate and press the push rod 8 to move downward, which can effectively alleviate the impact force, and after the rubber suction cup 10 is offset by the connecting plate 11, the rubber suction cup 10 is used for buffering. After the impact force is buffered, the rubber suction cup 10 will be adsorbed on the connecting plate 11, so that the rebound force of the concrete block after the impact is small, and it is not easy to have a secondary accident, effectively reducing the rebound of the cover plate 6 after buffering, and avoiding damage to other parts of the loader or nearby equipment and workers after the concrete bounces off. In addition, since micropores are opened on the connecting plate 11, after the air passes through the micropores, the rubber suction cup 10 no longer sucks the connecting plate 11 tightly, and then the compression spring 9 drives the push rod 8 to move upward, and the entire wing box assembly returns to its initial state;

[0026] Based on the above design, although this type of wing box sacrifices a certain amount of physical strength due to the structure of the side panels 4 and the enclosure 2, it is compensated by the cross plate 5. At the same time, the entire wing box can be made larger while being convenient for disassembly and repair, thereby expanding the protection range. The cover plate 6, which is most vulnerable, uses a compression spring 9 and a rubber suction cup 10 to buffer the impact force of the impact, ultimately reinforcing the wing box and ensuring that the wing box can provide better protection for the more fragile internal components such as the oil cylinder and suspension system.

[0027] Furthermore, a slide 12 is fixedly connected to the side wall of the front frame assembly body 1 close to the enclosure 2, and a support rod 13 is fixedly connected to the lower end of the slide 12. An arc groove is provided on the slide 12, and the cover plate 6 is arranged to abut against the arc groove. The slide 12 is arranged to limit the sliding range of the cover plate 6 to prevent the cover plate 6 from rotating too far and directly colliding with components such as the oil cylinder and the suspension system.

[0028] Furthermore, a plurality of reinforcing ribs 14 are provided on the front frame assembly body 1, and the reinforcing ribs 14 are fixedly connected to the enclosure 2, wherein the reinforcing ribs 14 are arranged inside the wing box assembly. The provision of the reinforcing ribs 14 can improve the physical strength of the enclosure 2 and enhance the anti-collision performance of the entire wing box.

[0029] Furthermore, a clearance opening is provided on the cover plate 6, and a rubber pad 15 is provided in the clearance opening;

[0030] At present, components such as oil cylinders and suspension systems often need to be connected to external pipelines, so the clearance port is provided to make way for the pipelines, and the rubber pad 15 is provided to prevent the cover plate 6 from scratching the pipelines when rotating.

[0031] Furthermore, a nut 16 is welded to the upper side wall of the enclosure 2 close to the side plate 4, and a screw 17 is internally threadedly connected to the nut 16, a pressing plate 18 is slidably connected to the screw 17, and the pressing plate 18 is disposed against the side plate 4;

[0032] In this design, the side plate 4 can be fixed by using the screw rod 17 in conjunction with the pressing plate 18 .

[0033] Furthermore, a ball head is provided at the upper end of the push rod 8 , and the provision of the ball head can reduce resistance when the cover plate 6 rotates, thereby preventing the lower surface of the cover plate 6 from being scratched or damaged.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
