Abstract
The utility model discloses a dust-proof pad of a laminated structure. The dust-proof pad of the laminated structure comprises a positioning piece, a base pad and a friction piece, the positioning piece and the base pad are both in a ring shape, the diameter of an axle hole of the positioning piece is smaller that that of an axle hole of the base pad, the base pad is mounted on the positioning piece in an embedded mode, an annular groove is formed in the outer surface of the base pad, and the friction piece is mounted in the annular groove in an embedded mode. The external diameter of the positioning piece is slightly larger than that of the base pad, the width of the friction piece is at least 15 mm, and at least one ring of friction protruding ribs is arranged on the upper surface of the friction piece. According to the dust-proof pad of the laminated structure, the base pad is mounted on the positioning piece through the function of positioning of the positioning piece, and the effect of separating dust and particulate matters is achieved through the function of fractioning sealing of the friction piece.
Description
Technical field
The utility model relates to a kind of laminated construction dust-proof cushion, is applied on the main shaft of tunnel excavator.
Background technique
The working environment of tunnel excavator is complicated, so often can enter dust or particle in the main shaft of tunnel excavator, easily causes spindle abrasion serious.Dust-proof cushion commonly used is a simple pad, adopts the flexible material manufacturing, and because working environment is complicated, after using a period of time, flexible material can dust stratification, aging, distortion etc., causes and can't play dustproof effect.
The model utility content
In order to prevent that dust and particle from entering in the main shaft of tunnel excavator, the utility model provides a kind of laminated construction dust-proof cushion.
The purpose of this utility model is come specific implementation by the following technical programs:
The laminated construction dust-proof cushion, comprise location piece, base wad and friction plate, described location piece and base wad are ring, the diameter of the axis hole of location piece is less than the diameter of the axis hole of base wad, base wad is Embedded to be arranged on location piece, be provided with the groove of annular on the outer surface of base wad, described friction plate be installed the inside grooves of annular is embedded.
The outer dia of described location piece is slightly larger than the outer dia of base wad.
The width of described friction plate is at least 15mm.
The upper surface of described friction plate is provided with at least one circle friction fin.
Through the laminated construction dust-proof cushion of above-mentioned design, by the positioning action of location piece, the base wad regulation is arranged on location piece, by the friction sealed effect of friction plate, reach the effect that dust and particulate matter are kept apart.
Description of drawings
The below is described in further detail the utility model according to drawings and embodiments.
Fig. 1 is the structural drawing of the described laminated construction dust-proof cushion of the utility model embodiment.
Embodiment
As shown in Figure 1, the described laminated construction dust-proof cushion of the utility model embodiment, comprise location piece 1, base wad 2 and friction plate 3, described location piece 1 and base wad 2 are ring, the diameter of the axis hole of location piece 1 is less than the diameter of the axis hole of base wad 2, base wad 2 is Embedded to be arranged on location piece 1, is provided with the groove of annular on the outer surface of base wad 2, described friction plate 3 is installed the inside grooves of annular is embedded.
The outer dia of described location piece 1 is slightly larger than the outer dia of base wad.
The width of described friction plate 3 is at least 15mm.
The upper surface of described friction plate 3 is provided with at least one circle friction fin 4.
Through the laminated construction dust-proof cushion of above-mentioned design, by the positioning action of location piece, the base wad regulation is arranged on location piece, by the friction sealed effect of friction plate, reach the effect that dust and particulate matter are kept apart.
