Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery equipment, and particularly relates to an excavator platform layout structure. Background Art

[0002] The working conditions that excavators are required to adapt to are also increasing. In some scenarios, excavators with a relatively narrow width are needed for operation. The slewing platform plays an important connecting role in the whole machine, and the slewing platform occupies a large width of the whole machine. Refer to the attached... Figure 1 As the existing platform layout structure, for a 20-ton excavator, the platform width is more than 2700mm, and the vehicle body is relatively wide.

[0003] In order to shorten the width of the whole machine, the straight main platform is straight. The left platform needs to install the cab installation area, and the left platform is not easy to modify. The widths of the right platform and the toolbox are easy to change in size, but the main pump structure is complex and not easy to modify. At the same time, the straight main platform on one side of the main pump installation area plays a blocking role. The engine installation area is set in the straight main platform, and the main pump installation area cannot be moved towards the direction of the straight main platform. Therefore, it is difficult to change the width of the existing platform layout structure, and it cannot enter the designated scenarios with a relatively narrow width for operation. Therefore, it is urgent to develop a new type of narrow-body platform. Content of the Utility Model

[0004] To achieve the above object, one or more embodiments of the present utility model provide the following technical solutions.

[0005] The present utility model provides an excavator platform layout structure, including a platform main body. S-shaped main beams are arranged in pairs at the center of the platform main body. A right platform is arranged on one side of the S-shaped main beams, and a left platform is arranged on the other side of the S-shaped main beams. A bending area is offset and arranged between the S-shaped main beams and close to the left platform;

[0006] An engine installation area is arranged in the second bending area, and a main pump installation area is arranged on the right platform on one side of the second bending area.

[0007] Further, a radiator installation area is arranged on the left platform on the other side of the bending area.

[0008] Further, a toolbox is arranged on the right platform above the main pump installation area.

[0009] Further, a battery installation area is stacked below the toolbox, and the toolbox and the battery installation area are integrated.

[0010] Further, a cab installation area is arranged on the left platform on one side of the radiator installation area.

[0011] Further configured such that the S-shaped main beam includes a bent beam, a first bent region is provided above the bent portion, and a second bent region is provided below the bent portion.

[0012] Further configured such that a reinforcing plate is provided above the bent beam, and the bent beam is the stress concentration area of the S-shaped main beam.

[0013] Further configured such that the reinforcing plate is vertically provided on the bent beam, and the reinforcing plate is an arc-shaped plate.

[0014] Further configured such that the reinforcing plate and the bent beam are integrally provided, and the reinforcing plate is welded to the top surface of the bent beam.

[0015] Further configured such that the width of the reinforcing plate is greater than the thickness of the bent beam.

[0016] Advantages of the above one or more technical solutions:

[0017] (1) Shorten the right platform, move the straight main platform and the right platform closer to the left, and the installation points of the engine installation area, radiator installation area, and main pump installation area are translated as a whole to the left. Move the installation point of the battery installation area to the position of the right front toolbox to save the rear space. The engine installation area falls on the main beam of the straight main platform. Since the installation point of the engine installation area moves to the left, the main beam bends correspondingly to the left to form an S shape. The original width of the right platform is about 870 mm. After the change, the width of the right platform is about 710 mm, with an overall indentation of 160 mm.

[0018] (2) There is stress concentration at the bent place. Therefore, by adding a reinforcing plate, the width of the upper cross-section of the main beam is increased, so that the stress is smoothly transitioned and the structural strength is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following combines with the attached drawings to illustrate the detailed implementation mode of this embodiment.

[0029] An excavator platform layout structure, referring to Figure 1 、 Figure 2 and Figure 3 , includes a platform main body 1. S-shaped main beams 2 are arranged in pairs at the center of the platform main body 1. A right platform 3 is arranged on one side of the S-shaped main beam 2, and a left platform 4 is arranged on the other side of the S-shaped main beam 2. A bending area is arranged offset and close to the left platform 4 between the S-shaped main beams 2; An engine installation area 22 is arranged in the second bending area 25, and a main pump installation area 32 is arranged on one side of the second bending area 25 and on the right platform 3.

[0030] Referring to Figure 1 , the platform main body 1 is mainly composed of the following components: the left platform 4, the straight main platform 5, and the right platform 3. The left platform 4 needs to install the cab installation area 41 and is not suitable for modification. Therefore, the main change points are concentrated on the straight main platform 5 and the right platform 3. Referring to Figure 2 , the straight main platform 5 of the existing platform main body 1 is improved to an S-shaped main beam 2, so that the main pump installation area 32 can shift inward towards the platform on the S-shaped main beam 2, reducing the distance between components such as the toolbox 31, battery installation area 42, main pump installation area 32, and engine installation area 22 of the platform main body 1. As a result, the right platform 3 can be shortened, and the straight main platform 5 and the right platform 3 move closer to the left, thereby narrowing the overall width and improving the degree of component integration.

[0031] A radiator installation area 43 is arranged on the other side of the bending area and on the left platform 4. A toolbox 31 is arranged above the main pump installation area 32 and on the right platform 3. The installation points of the engine installation area 22, radiator installation area 43, and main pump installation area 32 are translated as a whole to the left.

[0032] The battery installation area 42 is stacked below the toolbox 31, and the toolbox 31 and the battery installation area 42 are integrated. The installation point of the battery installation area 42 is moved to the position of the right front toolbox 31, saving the rear space.

[0033] A cab installation area 41 is arranged on the left platform 4 and on one side of the radiator installation area 43. The left platform 4 needs to install the cab installation area 41 and is not suitable for modification. Therefore, the main change points are concentrated on the positions of the original straight main platform 5 and the right platform 3.

[0034] The S-shaped main beam 2 includes a bent beam 23. A first bent area 24 is provided above the bent part, and a second bent area 25 is provided below the bent part. The engine installation area 22 is located on the main beam of the straight main platform. Since the installation point of the engine installation area 22 moves to the left, the main beam bends to the left correspondingly, forming an S shape.

[0035] There is stress concentration at the bent place. Therefore, a reinforcing plate 21 is provided above the bent beam 23. The width of the reinforcing plate 21 is greater than the width of the bent beam 23. The bent beam 23 is the stress concentration area of the S-shaped main beam 2. The reinforcing plate 21 is vertically arranged on the bent beam 23. The reinforcing plate 21 is an arc-shaped plate. The reinforcing plate 21 and the bent beam 23 are integrally arranged. The reinforcing plate 21 is welded to the top surface of the bent beam 23. The integrally arranged reinforcing plate 21 and the bent beam 23 increase the width of the upper section of the main beam, enabling the stress to transition smoothly and improving the structural strength.

[0036] By adopting the S-shaped main beam 2, the width of the optimized right platform 3 is 710 mm. The original width of the right platform 3 is about 870 mm, which is indented by 160 mm compared with the original width of the right platform 3. The use of the S-shaped main beam 2 does not require the improvement of the size of the main pump installation area 32, and the movement of the main pump installation area 32 can be completed. This makes space available at the original position of the main pump installation area 32 on the right platform 3. After cutting the space on the right side of the main pump installation area 32 and shortening the widths of the toolbox and the battery, space is available at the original toolbox 31 on the right platform 3. After cutting the space on the right side of the toolbox 31, the overall width of the right platform 3 is indented by 160 mm.

[0037] Although the specific implementation manners of the present invention are described above in conjunction with the drawings, it is not a limitation to the protection scope of the present invention. Those skilled in the art should understand that based on the technical solutions of the present invention, various modifications or deformations that can be made by those skilled in the art without creative efforts are still within the protection scope of the present invention.
