Description

Technical Field

[0001] This utility model relates to the field of electric shovel boom connecting cylinder technology, and in particular to a semi-circular structure electric shovel boom connecting cylinder. 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] To increase the bucket opening angle, a through hole is made in the connecting sleeve. However, making a through hole reduces the strength of the connecting through hole, so reinforcing ribs need to be installed to increase the strength of the connecting sleeve.

[0004] However, existing connecting cylinders require a large number of reinforcing ribs to be installed on the outside of the connecting cylinder in order to ensure its structural strength, which increases the cost of use.

[0005] Furthermore, the existing connecting tube reduces the opening angle of the bucket door, which leads to a decrease in the working efficiency of the bucket. Utility Model Content

[0006] To address the aforementioned problems in the existing technology, a semi-circular structure electric shovel boom connecting cylinder is provided.

[0007] The specific technical solution is as follows:

[0008] A semi-circular structure electric shovel boom connecting cylinder is designed, including a main body, a top reinforcing ring, and an opening. The opening is provided on one side of the main body, the top reinforcing ring is provided above the opening, the bottom reinforcing ring is provided below the opening, a reinforcing plate is provided below the top reinforcing ring, and a reinforcing column is provided at the edge of the opening. A circular shell is provided on the back of the main body, and a support plate is connected to the inside of the circular shell by welding.

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

[0010] Preferably, the inner wall of the bottom reinforcing ring is connected to the outer wall of the main body by welding, and the top of the bottom reinforcing ring is connected to the bottom of the circular shell by welding.

[0011] Preferably, a support plate is provided inside the circular shell, one end of the circular shell is connected to the outer wall of the main body by welding, one end of the support plate is connected to the inner wall of the circular shell by welding, and the other end of the support plate is connected to the main body by welding.

[0012] Preferably, the top of the reinforcing plate is connected to the bottom of the top reinforcing ring by welding, the bottom of the reinforcing plate is connected to the top of the bottom reinforcing ring by welding, and the reinforcing plates are evenly distributed on the outer wall of the main body.

[0013] Preferably, the middle part of the reinforcing plate is connected to the middle reinforcing ring by welding, and one side of the middle reinforcing ring is connected to the main body by welding.

[0014] Preferably, the reinforcing column is connected to the edge of the opening by welding, and both the top reinforcing ring and the bottom reinforcing ring have through holes.

[0015] The above technical solution has the following advantages or beneficial effects:

[0016] 1. By setting up reinforcing columns and a circular shell, the circular shell and support plate on the back of the main body are used to support the opening of the main body. The circular shell and the top and bottom reinforcing rings form a triangular structure on the back of the main body. At the same time, the support plate is also triangular in shape to increase the strength of the main body and prevent the main body from bending towards the opening or bending outward. The reinforcing plate is used to prevent the top and bottom reinforcing rings from tilting. Meanwhile, the reinforcing columns on the opening are used to increase the strength of the groove edge, further increasing the strength of the main body. There is no need to use a lot of reinforcing ribs to reinforce the main body, which effectively reduces the cost of use.

[0017] 2. By setting up openings, the L-shaped support rods and bucket doors can open to a larger unloading angle, which facilitates the rapid dropping of materials inside the bucket and effectively improves the working efficiency of the bucket. Attached Figure Description

[0028] Reference Figure 1-5 A semi-circular structure electric shovel boom connecting cylinder includes a main body 1, a top reinforcing ring 3, and an opening 2. An opening 2 is provided on one side of the main body 1. A top reinforcing ring 3 is located above the opening 2, and a bottom reinforcing ring 4 is located below the opening 2. A reinforcing plate 6 is located below the top reinforcing ring 3. Reinforcing posts 5 are provided at the edge of the opening 2. A circular shell 7 is provided on the back of the main body 1. A support plate 8 is connected to the inside of the circular shell 7 by welding. The circular shell 7 and the support plate 8 on the back of the main body 1 support the opening 2. The circular shell 7, the top reinforcing ring 3, and the bottom reinforcing ring 4 form a triangular structure on the back of the main body 1. The support plate 8 is also triangular, used to increase the strength of the main body 1 and prevent it from bending towards the opening 2 or outwards. The reinforcing plate 6 prevents the top reinforcing ring 3 and the bottom reinforcing ring 4 from tilting. The reinforcing posts 5 on the opening 2 increase the strength of the groove edge, further increasing the strength of the main body 1. This eliminates the need for numerous reinforcing ribs to strengthen the main body 1, effectively reducing operating costs.

[0029] Furthermore, the inner wall of the top reinforcing ring 3 is connected to the outer wall of the main body 1 by welding, and the bottom of the top reinforcing ring 3 is connected to the top of the circular shell 7 by welding. Multiple support plates 8 are provided inside the circular shell 7 to prevent the circular shell 7 from bending and to enhance the strength of the circular shell 7.

[0030] Furthermore, the inner wall of the bottom reinforcing ring 4 is connected to the outer wall of the main body 1 by welding, and the top of the bottom reinforcing ring 4 is connected to the bottom of the circular shell 7 by welding. The bottom reinforcing ring 4 has the same structure as the bottom reinforcing ring 5. Both the bottom reinforcing ring 4 and the bottom reinforcing ring 5 have through holes 9, which are evenly distributed on them, and the opening 2 is L-shaped.

[0031] Furthermore, the circular shell 7 has a support plate 8 inside. One end of the circular shell 7 is connected to the outer wall of the main body 1 by welding. The inner wall of the circular shell 7 is connected to one end of the support plate 8 by welding. The other end of the support plate 8 is connected to the main body 1 by welding. The top of the circular shell 7 is semi-circular. The two ends of the bottom of the circular shell 7 are respectively connected to the two sides of the back of the main body 1 in the form of flared openings, forming a triangular structure.

[0032] Furthermore, the top of the reinforcing plate 6 is connected to the bottom of the top reinforcing ring 3 by welding, and the bottom of the reinforcing plate 6 is connected to the top of the bottom reinforcing ring 4 by welding. The reinforcing plates 6 are evenly distributed on the outer wall of the main body 1. The top reinforcing ring 3 and the bottom reinforcing ring 4 are located at the upper and lower ends of the opening 2 respectively to support the main body 1. The opening 2 is supported by the circular shell 7 and the support plate 8 on the back of the main body 1.

[0033] Furthermore, the middle of the reinforcing plate 6 is connected to the middle reinforcing ring 10 by welding, and one side of the middle reinforcing ring 10 is connected to the main body 1 by welding. The middle reinforcing ring 10 is used to support the reinforcing plate 6, increase the strength of the reinforcing plate 6, and prevent the reinforcing plate 6 from tilting or bending. The opening 2 is approximately 70mm.

[0034] Furthermore, the edge of the opening 2 is connected to the reinforcing column 5 by welding. Both the top reinforcing ring 3 and the bottom reinforcing ring 4 are provided with through holes 9. The through holes 9 are used to disperse stress around the through holes 9 to prevent deformation or cracking caused by stress concentration.

[0035] Working principle: When using this device, the circular shell 7 and support plate 8 on the back of the main body 1 are used to support the opening 2 of the main body 1. The circular shell 7, the top reinforcing ring 3 and the bottom reinforcing ring 4 form a triangular structure on the back of the main body 1. At the same time, the support plate 8 is also triangular in shape to increase the strength of the main body 1 and prevent the main body 1 from bending towards the opening 2 or bending outward. The reinforcing plate 6 is used to prevent the top reinforcing ring 3 and the bottom reinforcing ring 4 from tilting. Meanwhile, the reinforcing column 5 on the opening 2 is used to increase the strength of the groove edge, further increasing the strength of the main body 1, so that the L-shaped support rod and the bucket door can open a larger unloading angle, which makes it easier for the material inside the bucket to fall quickly, thus completing the work.

[0036] 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.
