Description

Walking crawler chassis in deep sea polymetallic nodule mining area

technical field

The utility model relates to a walking crawler chassis, in particular to a walking crawler chassis in a deep-sea polymetallic nodule mining area.

Background technique

Different from terrestrial soils, the seabed surface sediments in deep-sea polymetallic nodule mining areas are thin and soft, with weak bearing capacity and high water content.

At present, the walking technology on the deep-sea thin soft sediment adopts the crawler driving mechanism. Due to the traditional driving track on land, it will sink deep into the sediment and slip on the spot. The existing crawler driving mechanism adopts sharp and high grouser teeth to improve the traction performance of the crawler vehicle on thin and soft sediments. The test found that the crawler traveling mechanism had too much adhered sediment, and the track shoe teeth were partially damaged, which restricted the traction performance of the tracked vehicle.

Utility model content

The technical problem to be solved by the utility model is to overcome the above-mentioned defects in the prior art, and provide a walking crawler chassis with less adhesion deposits and good traction performance in the deep-sea polymetallic nodule mining area.

The technical scheme adopted by the utility model to solve its technical problems is that the crawler chassis of the deep-sea polymetallic nodule mining area includes crawlers, support arms, trolley frames, driving wheels, guide wheels and crawler frames, and the support arms are arranged on the trolley. The other end of the support arm is fixedly connected to the track frame plate. The driving wheels and guide wheels are respectively arranged at the front and rear ends of the track frame. On the left and right sides of the track frame, thin mudguards are fixedly connected.

Further, the crawler frame is provided with an oil tank, a pressure compensation box, a valve box and a buoyancy material box, the oil tank can be loaded with hydraulic oil to reduce the mechanism of the hydraulic system; the pressure compensation box is used to replenish oil to the hydraulic system, so The buoyancy material box is provided with buoyancy material.

Further, at least two load-bearing wheels are fixedly connected to the bottom of the track frame for supporting the track and the track chain.

Further, the arrangement of the bearing wheels is an array.

Further, the shape of the track frame is an upper wide trapezoid, which is welded by frame-type plates.

Further, the fastening method is bolt connection or welding.

Compared with the prior art, the utility model has the advantages of simple structure, low manufacturing cost, high walking efficiency, and can prevent the crawler chassis from sinking during driving, causing the thin and soft sediments on both sides to collapse inward and adhere to the track shoes to reduce the driving performance. , The left and right sides of the crawler frame are fixed with thin beam fenders; the service life is long, and the crawler frame is a frame welding mechanism.

Description of drawings

Fig. 1 is a schematic structural view of an embodiment of the utility model.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

With reference to accompanying drawing 1, present embodiment comprises crawler belt 1, support arm 2, trolley frame 3, driving wheel 4, guide wheel 5 and crawler frame 12, and described support arm 2 is located at the both sides of trolley frame 3, and described The other end of the support arm 2 is welded to the crawler frame 12, the driving wheel 4 and the guide wheel 5 are respectively arranged at the front and rear ends of the crawler frame 12, and the crawler belt 1 bypasses the driving wheel 4 and the guide wheel 5 and is arranged on the crawler frame 12 superior.

The track frame 12 is provided with an oil tank 6, a pressure compensation box 7, a valve box 10 and a buoyancy material box 8. The oil tank 6 can be loaded with hydraulic oil to reduce the mechanism of the hydraulic system; the pressure compensation box 7 is used to supplement the hydraulic system. Oil and buoyancy material are placed in the buoyancy material box 8, which has a compact structure and is easy to install.

The left and right sides of the crawler frame 12 are connected with the thin fenders 11 by bolts to prevent the chassis of the crawler 1 from sinking during driving so that the thin and soft deposits on both sides collapse inward and attach to the crawler 1 .

At least two bearing wheels 9 are fixedly connected to the bottom of the crawler frame 12 for supporting the crawler belt 1 and the crawler belt chain.

The arrangement mode of bearing wheel 9 is array mode.

The track frame 12 is shaped as an upper wide trapezoid, which is welded by frame plates to further improve the passability of the track 1 chassis.

Using the utility model, the walking efficiency is high, and it can prevent the crawler chassis from sinking during driving, causing the soft sediment on both sides to collapse inward and attach to the track shoes to reduce the driving performance. Mudguard; long service life, track frame is a frame welding mechanism.
