Description

Technical Field

[0001] This utility model relates to the field of electric shovel boom connecting cylinder technology, and in particular to an electric shovel boom connecting cylinder with a square reinforcing rib. Background Technology

[0002] An electric shovel, also known as a rope shovel or cable shovel, is a mechanical electric excavator that uses gears, chains, steel cables, pulleys, and other transmission components to transmit power in a single-bucket excavator.

[0003] After installing a boltless bucket on the existing electric shovel boom, the space between the boom connecting tube and the bucket is relatively narrow, resulting in an excessively small opening angle for the bucket door, which affects the efficiency of unloading.

[0004] The existing connecting cylinders lack reinforcement structures and are prone to deformation after prolonged use, requiring regular replacement or repair, which increases operating costs. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, an electric shovel boom connecting cylinder with a square reinforcing rib is provided.

[0006] The specific technical solution is as follows:

[0007] Design a connecting cylinder for an electric shovel bucket arm with square reinforcing ribs, including a main body, a top reinforcing ring, and a central opening. The central opening is located on one side of the main body, and the top reinforcing ring is located above the central opening. The central openings are distributed at the front end and one side of the main body. A bottom reinforcing ring is located below the central opening. A side reinforcing plate is located on the side of the main body away from the central opening. A connecting plate is connected to one side of the side reinforcing plate by welding. The side reinforcing plates are evenly distributed on the main body.

[0008] Preferably, the inner side of the top reinforcing ring is connected to the outer wall of the main body by welding, and the top reinforcing ring is connected to the side reinforcing plate by welding.

[0009] Preferably, the inner wall of the bottom reinforcing ring is connected to the outer wall of the main body by welding, the bottom reinforcing ring is connected to the bottom of the side reinforcing plate by welding, and the side reinforcing plate is connected to the outer wall of the main body by welding.

[0010] Preferably, the top of the top reinforcing ring is provided with a triangular plate, the bottom of the triangular plate is connected to the top reinforcing ring by welding, and one end of the triangular plate is connected to the outer wall of the main body by welding.

[0011] Preferably, both the top reinforcing ring and the bottom reinforcing ring have through holes, and the through holes are distributed at equal intervals on the top reinforcing ring and the bottom reinforcing ring.

[0012] Preferably, the side reinforcement plate is provided with triangular plates at both the upper and lower ends, and the triangular plates and the side reinforcement plate form a trapezoid.

[0013] Preferably, the connecting plates are symmetrically distributed on the back of the main body, and a square is formed between the connecting plates and the side reinforcement plates.

[0014] The above technical solution has the following advantages or beneficial effects:

[0015] 1. By setting a central opening, when using the excavating device, the central opening of nearly 70mm in the middle of the main body allows the L-shaped support rod and bucket door to open to a larger unloading angle, thereby increasing the opening angle of the bucket door and improving the working efficiency of the equipment in opening and unloading.

[0016] 2. By setting a top reinforcing ring and side reinforcing plates, and with top and bottom reinforcing rings respectively installed at the upper and lower ends of the central opening, the top and bottom reinforcing rings are used to prevent the main body from denting inward or protruding outward during use. At the same time, by setting side reinforcing plates and triangular plates, the side reinforcing plates and triangular plates are respectively used to reinforce the vertical of the main body on the other side of the central opening. The connecting plate and the side reinforcing plates form a square to reinforce the side reinforcing plates, preventing the main body from bending towards the central opening due to the central opening, reducing the cost of use and demonstrating the practicality of this device.

[0024] 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.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0027] Reference Figure 1-5 An electric shovel bucket rod connecting cylinder with square reinforcing ribs includes a main body 1, a top reinforcing ring 3, and a central opening 2. The central opening 2 is located on one side of the main body 1, and the top reinforcing ring 3 is located above the central opening 2. The central opening 2 is distributed at the front end and one side of the main body 1. The bottom reinforcing ring 4 is located below the central opening 2. The side reinforcing plate 5 is located on the side of the main body 1 away from the central opening 2. The side reinforcing plate 5 is connected to the connecting plate 6 by welding. The side reinforcing plates 5 are evenly distributed on the main body 1. When the excavating device is used, the central opening 2, which is nearly 70mm in diameter, allows the L-shaped support rod and bucket door to open at a larger unloading angle, thereby increasing the opening angle of the bucket door and improving the working efficiency of the equipment in opening and unloading the bucket.

[0028] Furthermore, the inner side of the top reinforcing ring 3 is connected to the outer wall of the main body 1 by welding, and the top reinforcing ring 3 is connected to the side reinforcing plate 5 by welding. The reinforcing ring and the side reinforcing plate 5 are connected by welding, and the main body 1 is a connecting cylinder.

[0029] Furthermore, the inner wall of the bottom reinforcing ring 4 is connected to the outer wall of the main body 1 by welding, the bottom of the bottom reinforcing ring 4 is connected to the bottom of the side reinforcing plate 5 by welding, and the side reinforcing plate 5 is connected to the outer wall of the main body 1 by welding. The side reinforcing plate 5 is used to prevent the main body 1 from bending towards the central opening 2 because it has a central opening 2.

[0030] Furthermore, a triangular plate 8 is provided at the top of the top reinforcing ring 3. The bottom of the triangular plate 8 is connected to the top reinforcing ring 3 by welding. One end of the triangular plate 8 is connected to the outer wall of the main body 1 by welding. The triangular plates 8 are located at the upper and lower ends of each side reinforcing plate 5. The triangular plates 8 are used to prevent the top reinforcing ring 3 and the bottom reinforcing ring 4 from tilting.

[0031] Furthermore, both the top reinforcing ring 3 and the bottom reinforcing ring 4 are provided with through holes 7. These through holes 7 are evenly spaced on both rings. The main function of the through holes 7 is to disperse stress and prevent deformation and cracking. By creating through holes 7 in each structure, stress can be concentrated around the holes, thus avoiding deformation or cracking caused by stress concentration. Specifically, reinforcing ribs are typically used to increase the strength and stiffness of the structure and reduce deformation and warping. Without increasing the wall thickness, reinforcing ribs can improve the strength and rigidity of the product, save material usage, reduce weight, and lower costs.

[0032] Furthermore, triangular plates 8 are respectively provided at the upper and lower ends of the side reinforcement plate 5. The triangular plates 8 and the side reinforcement plate 5 form a trapezoid. The triangular plates 8 and the side reinforcement plate 5 together form a trapezoid. Triangles have stability. Triangular plates 8 are used to reinforce the upper and lower ends of the main body 1.

[0033] Furthermore, the connecting plate 6 is symmetrically distributed on the back of the main body 1, and a square is formed between the connecting plate 6 and the side reinforcing plate 5. The connecting plate 6 and the side reinforcing plate 5 will form a square on the back of the main body 1, which is used to make the fixing ring form a ring. The reinforcing ring is also used to reinforce the side reinforcing plate 5 and prevent the side reinforcing plate 5 from tilting on the main body 1.

[0034] Working principle: When using this device, the excavator has a central opening 2 of approximately 70mm in the middle of the main body 1. This allows the L-shaped support rod and bucket door to open at a larger unloading angle, increasing the bucket door's opening angle. A top reinforcing ring 3 and a bottom reinforcing ring 4 are respectively installed at the upper and lower ends of the central opening 2. These rings prevent the main body 1 from denting inward or protruding outward during use. Simultaneously, side reinforcing plates 5 and triangular plates 8 are installed on the other side of the central opening 2 to vertically reinforce the main body 1. A connecting plate 6 and the side reinforcing plates 5 form a square to further reinforce the side reinforcing plates 5, preventing the main body 1 from bending towards the central opening 2. This completes the operation.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
