Description

Full protection track caterpillar track guard plate structure suitable for large excavator

Technical Field

The utility model belongs to a part for the engineering machine tool, specifically speaking especially relates to a full protection track caterpillar track guard plate structure suitable for large-scale excavator.

Background

The crawler excavator is generally provided with a crawler caterpillar guard plate which is mainly used for preventing the caterpillar from derailing and protecting the crawler caterpillar. In order to improve the protection effect, the large excavator often needs to be provided with a full-protection crawler guard plate, so that the falling fault of the crawler track under the severe working conditions of mines and the like can be effectively prevented, and the service life of the chassis part is prolonged. When the large excavator walks under the rugged working condition of uneven road surface for a long time, the crawler belts on the two sides can deviate and fall off under the action of lateral force, the guard area of the guard plate of the full-protection crawler track caterpillar track is increased, the crawler belt can be effectively prevented from falling off, but the guard plate and the crawler track caterpillar track are often interfered by mutual abrasion due to improper design, and therefore the service life of the crawler track caterpillar track is seriously influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a full protection track caterpillar track backplate structure suitable for large-scale excavator to overcome among the prior art full protection track caterpillar track backplate structure backplate and track caterpillar track mutual wear and tear and interfere, thereby seriously influence the life's of track caterpillar track defect.

The utility model discloses an adopt following technical scheme to realize:

the utility model provides a full protection track caterpillar track of a tractor protection plate structure suitable for large-scale excavator, includes at least two sets of backplate units, the backplate unit includes two risers, two connecting plates and four fixed bent plates, connecting plate fixed connection is between two risers, and four fixed bent plate symmetries set up on two risers.

Furthermore, the fixed bent plate is fixedly connected with a reinforcing plate A.

Furthermore, the fixed bent plate is provided with a through hole.

Furthermore, the edge in the riser is stupefied and is equipped with the chamfer.

Further, a reinforcing plate B traversing the vertical plate is arranged at the bottom of the vertical plate.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a backplate project organization of universalization, the structure is simple relatively, easily assembly and preparation, when realizing the full protective effect of track caterpillar track, has avoided under the abominable operating mode track caterpillar track and backplate to take place the risk of wearing and tearing each other.

In the figure: 1. a vertical plate; 2. a connecting plate; 3. fixing the bent plate; 4. a through hole; 5. a reinforcing plate A; 6. a reinforcing plate B; 7. chamfering; 8. a shield unit.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 to 3, full protection track caterpillar protection plate structure suitable for large excavator, including four group's backplate units 8, backplate unit 8 includes two risers 1, two connecting plates 2 and four fixed

bent plates

3, and 2 fixed connection of connecting plate are between two risers 1, and four fixed bent plates 3 symmetry sets up on two risers 1. The vertical plate 1 mainly plays a role in preventing the caterpillar track of the caterpillar from falling off; the fixed bent plate 3 is used for connecting a lower frame.

Further, the fixed bent plate 3 is fixedly connected with a reinforcing plate a 5. The reinforcing plate A5 is used for reinforcing the strength of the fixed bent plate 3, and the splicing welding structure of the fixed bent plate 3 and the reinforcing plate A5 solves the problem of limited moulds in two bending processes.

Furthermore, the fixed bent plate 3 is provided with a phi 22 through hole 4, and the guard plate unit 8 is fixed on the lower frame by the fixed bent plate 3 through a bolt penetrating through the through hole 4.

Further, as shown in fig. 2, for solving the problem that the caterpillar track of a belt can have the critical problem of the quality of the influence of the risk that caterpillar track and protecting plate edge wear interfere in the slippage process of the thrust wheel during the working process of the full-protection protecting plate structure under the severe working condition of the walking work of the uneven road surface for a long time, the three-dimensional simulation of the slippage process of the caterpillar track of a belt is verified, on the one hand, the height value of the vertical plate 1 is optimized, on the other hand, the chamfer 7 design is added to the edges of the two sides of the vertical plate 1, and through the structural optimization design of the two aspects, the problem is well solved.

Furthermore, a reinforcing plate B6 traversing the vertical plate 1 is arranged at the bottom of the vertical plate 1. The reinforcing plate B6 is used to reinforce the strength of the riser 1.

As shown in figure 3, 4 same guard plate units 8 are assembled on one side, the thrust wheels are positioned in the cavities of the vertical plates 1 on the two sides, and the guard plate units 8 can realize full protection on the caterpillar track after being assembled. Compare and arrange two backplate structures in the unilateral, the utility model discloses among the backplate arrangement structure, single backplate unit 8's weight is lighter, and length size is shorter, convenient assembly and preparation, and whole visual effect is more succinct compact.
