Description

Excavator chassis heightening device

Technical Field

The utility model relates to the technical field of mechanical equipment, especially, relate to an excavator chassis heightening device.

Background

An excavator, also known as an excavating machine (excavating shovel), is an earth moving machine that excavates material above or below a bearing surface with a bucket and loads the material into a transport vehicle or unloads the material to a stockyard. The materials excavated by the excavator mainly comprise soil, coal, silt, soil subjected to pre-loosening and rocks. In view of the development of construction machines in recent years, the development of excavators is relatively fast, and the excavator has become one of the most important construction machines in construction.

Common excavator structures include: the device comprises a chassis, a swing mechanism, a host machine, a power device, a working device, an operating mechanism, a transmission mechanism, a walking mechanism, auxiliary facilities and the like. At present, the chassis of the excavator is generally in a straight type and is relatively close to the ground, as shown in figure 3. However, the working environment of the excavator is usually severe, for example, a wet and muddy environment such as a ditch and a mud ditch, and meanwhile, the excavator often sinks seriously due to loose and soft ground, so that the risk of water entering the engine exists, and the engine is damaged to cause complete machine breakdown.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the following embodiments.

As shown in FIGS. 1-2; the utility model provides a heightening device for an excavator chassis, which comprises two flanges 1 arranged in parallel and a bracket 2 vertically connected above the two flanges 1; a plurality of first mounting holes 3 are formed in the flange 1 and used for connecting a walking device of an excavator, and the bracket 2 is used for supporting a slewing device; the support 2 comprises a beam part 4 positioned in the middle and frame leg parts 5 positioned on two sides, wherein the upper surface of the beam part 4 is horizontal, and the lower surface is arched; the leg part 5 is 800mm higher than the flange 600-.

In order to improve the stability of the connection, in the above-mentioned excavator chassis heightening device, as a preferred embodiment, two brackets 2 are provided side by side, and are respectively located at the front side and the rear side of two flanges 1 arranged in parallel. The flange 1 is formed with a reinforcing rib 6. And a clamping groove matched with the reinforcing rib 6 is formed in one side of the support leg part 5, and the reinforcing rib 6 is fixedly welded after being clamped in the clamping groove. The flange 1 and the bracket 2 are welded and fixed.

In order to facilitate the connection of the flange 1 with a running gear of an excavator, the first mounting hole 3 is located on the same side of the reinforcing rib 6 away from the leg part 5. In order to facilitate the connection of the bracket 2 with the swing mechanism, a second mounting hole 7 is formed on the upper surface of the bracket 2. For example, the support plate may be mounted on the bracket and then the swing mechanism may be mounted on the support plate.

The utility model provides an excavator chassis heightening device compares with the excavator chassis of current straight structure (as shown in fig. 3), has improved the chassis height, under the operation environment of excavator is more abominable (moist, muddy environment such as ditch, mud ditch), avoids water to get into to the engine and then causes the paralytic problem of complete machine.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the present invention. Accordingly, the foregoing description is illustrative in nature and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
