Abstract
The utility model discloses a waterproof and dustproof device on an engineering machinery upper frame, which belongs to the technical field of waterproof and dustproof devices. The waterproof and dustproof device includes a rubber pad, a cover plate, gaskets and bolts. Corresponding through holes are arranged in the rubber pad and the cover plate, and the bolts pass through the through holes in the gaskets, the cover plate and the rubber pad sequentially. The device has the benefits of protecting parts under a round hole and avoiding influences on work done through the round hole, such as installation, maintenance, and overhaul.
Description
Technical field
The utility model relates to a kind of dust and water proof apparatus, relates in particular to vehicle frame dust and water proof apparatus on a kind of engineering machinery, belongs to the dust and water proof apparatus technical field.
Background technique
At present, as shown in Figure 1 for the ease of operations such as installation, maintenance, inspections, most engineering machinery is offered the circular hole (2) of different-diameter on last vehicle frame (1) through regular meeting in operation process.Generally speaking, the circular hole of these different-diameters all is in idle state, thereby foreign material such as dust, rainwater can enter into the component below the circular hole through these circular holes, thereby component are polluted, destroy, and influences its performance.So, certain research and development meaning is arranged to the dust and water proof apparatus of this type of circular hole.
Summary of the invention
Be prone to defective contaminated, that destroy in order to overcome the component that are positioned at below the circular hole; The utility model provides vehicle frame dust and water proof apparatus on a kind of engineering machinery; Not only protect the component below the circular hole, also do not influenced work such as the installation, maintenance carried out through circular hole, inspection.
The utility model is for realizing above-mentioned purpose; Realize through following technological scheme: vehicle frame dust and water proof apparatus on a kind of engineering machinery; Comprise rubber pad, cover plate, packing ring and bolt, rubber pad and cover plate are provided with corresponding through hole, and bolt runs through the through hole of packing ring, cover plate and rubber pad successively.
Further, the shape of rubber pad and cover plate is complementary.
Further, the marginal dimension of rubber pad, cover plate is greater than the size of circular hole on the last vehicle frame.
The beneficial effect of the utility model is: compare with the situation of supreme vehicle frame dust and water proof apparatus in the past; This device has not only been protected the component below the circular hole; The working life of elongated component, simultaneously for convenience detach, do not influence work such as installation, maintenance through circular hole, inspection yet.
Description of drawings
Fig. 1 is the structural representation of vehicle frame on the engineering machinery in the existing technology;
Fig. 2 is the structural representation of the last vehicle frame that cooperates with the utility model;
Fig. 3 is the assembling schematic representation of the utility model;
Fig. 4 is the assembling design sketch of the utility model.
Among the figure: 1, go up vehicle frame, 2, circular hole, 3, the A tapped hole, 4, the B tapped hole, 5, rubber pad, 6, cover plate, 7, packing ring, 8, bolt.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 3, the utility model comprises rubber pad 5, cover plate 6, packing ring 7 and bolt 8, and rubber cushion 5 is provided with corresponding through hole with cover plate 6, and bolt 8 runs through the through hole of packing ring 7, cover plate 6 and rubber pad 5 successively.
Wherein, the shape of rubber pad 5 and cover plate 6 is complementary, and the marginal dimension of rubber pad 5, cover plate 6 is greater than the size of circular hole 2 on the last vehicle frame 1, so that better water proof and dust proof etc.
During assembling, earlier 2 liang of STHs of circular hole of last vehicle frame 1 several, as shown in Figure 3, offered A tapped hole 3 and B tapped hole 4, then rubber pad 5, cover plate 6 are fixed upward on the vehicle frames 1 through A tapped hole 3, B tapped hole 4 with packing ring 7, bolt 8 by order among the figure.
During use, as shown in Figure 4, when the circular hole 2 of last vehicle frame 1 does not need work, adopt this device to seal; When carrying out work such as installation, maintenance, inspection when needs, again this device is removed.
Claims (3)
1. vehicle frame dust and water proof apparatus on the engineering machinery; It is characterized in that; Comprise rubber pad (5), cover plate (6), packing ring (7) and bolt (8); Rubber pad (5) and cover plate (6) are provided with corresponding through hole, and bolt (8) runs through the through hole of packing ring (7), cover plate (6) and rubber pad (5) successively.
