Abstract

A separated floating seal for a work arm of a heading machine comprises a floating seal base, a floating seal frame and a floating seal body. A first annular groove is formed in the right end face of the floating seal base and a second annular groove is formed in the left end face of the floating seal frame. The first annular groove and the second annular groove are communicated with each other so that a seal body installation space can be formed. The floating seal body is arranged in the seal body installation space. A first separating body is arranged in the portion, between the floating seal base and the floating seal body, in the seal body installation space. A second separating body is arranged between the floating seal frame and the floating seal body. The separated floating seal for the work arm of the heading machine is convenient to repair and replace and low in repair cost.

Description

For the separated type floating seal on development machine working arm
Technical field
The utility model relates to a kind of sealing configuration, relates to specifically a kind of separated type floating sealing structure.
Background technique
Floating sealing structure on existing development machine working arm as shown in Figure 1, comprise floating seal seat 1, floating seal frame 3, floating seal body 5, this structure component are few, it is also relatively convenient to process, but in actual use,, because the wearing and tearing of on floating seal seat 1, floating seal the frame 3 and groove position of floating seal body 5 connecting parts are more serious, cause poorly sealed, generation leakage of oil, and the inconvenience of above-mentioned groove position is repaired, integral replacing cost is very high.
Model utility content
The purpose of this utility model is to provide a kind of for the separated type floating seal on development machine working arm, and it is convenient to maintain and replace, and maintenance cost is low.
To achieve these goals, technical solution of the present utility model is: a kind of for the separated type floating seal on development machine working arm, comprise floating seal seat, floating seal frame, floating seal body, on the right side of floating seal seat, have the first circular groove, on the left side of floating seal frame, have the second circular groove, first, the second circular groove is interconnected and forms seal installing space, floating seal body is located in described seal installing space, between the inherent described floating seal seat of described seal installing space and floating seal body, be provided with the first detached body, between floating seal frame and floating seal body, be provided with the second detached body.
The utility model is for the separated type floating seal on development machine working arm, wherein, described the first detached body is circular, comprise bottom surface and sidewall, the bottom surface of described the first detached body, sidewall respectively with the bottom surface of described the first circular groove, the sidewall contact of the first circular groove, described the second detached body is circular, comprises bottom surface and sidewall, the bottom surface of described the second detached body, sidewall respectively with the bottom surface of described the second circular groove, the sidewall contact of the second circular groove.
The utility model, for the separated type floating seal on development machine working arm, wherein, is provided with seal ring between the sidewall of described the first detached body and the sidewall of the first circular groove, between the sidewall of described the second detached body and the sidewall of the second circular groove, is provided with seal ring.
Adopt after such scheme, because the utility model is provided with first, second detached body for the separated type floating seal on development machine working arm in seal installing space, therefore in the time that the groove position of separated type floating seal produces wearing and tearing, be first, second detached body wearing and tearing, when maintenance, only need change first, second detached body, easy to maintenance, maintenance cost is low.
Brief description of the drawings
Fig. 1 is the existing sectional view for the separated type floating seal on development machine working arm;
Fig. 2 is the sectional view of the utility model for the separated type floating seal on development machine working arm.
Embodiment
As shown in Figure 2, the utility model is for the separated type floating seal on development machine working arm, comprise floating seal seat 11, floating seal frame 13, floating seal body 15, on the right side of floating seal seat 11, have the first circular groove 111, on the left side of floating seal frame 13, have the second circular groove 131, first, the second circular groove 111, 131 are interconnected forms seal installing space 17, floating seal body 15 is located in seal installing space 17, between the inherent floating seal seat 11 of seal installing space 17 and floating seal body 15, be provided with the first detached body 12, between floating seal frame 13 and floating seal body 15, be provided with the second detached body 14, the first detached body 12 is circular, comprise integrated bottom surface 121 and sidewall 122, the bottom surface 121 of the first detached body, the bottom surface of sidewall 122 respectively with the first circular grooves 111, the sidewall contact of the first circular groove 111, the second detached body 14 is circular, comprise integrated bottom surface 141 and sidewall 142, the bottom surface 141 of the second detached body 14, the bottom surface of sidewall 142 respectively with the second circular grooves 131, the sidewall contact of the second circular groove 131, between the sidewall 122 of the first detached body and the sidewall of the first circular groove 111, be provided with O RunddichtringO 16, between the sidewall 142 of the second detached body and the sidewall of the second circular groove 131, be provided with O RunddichtringO 18.
The utility model is for the separated type floating seal on development machine working arm, relatively rotating due to floating seal seat 11 and floating seal frame 13 in working procedure, make first, second detached body 12,14 produce wearing and tearing, when maintenance, only need change first, second detached body.
The above embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that the common engineers and technicians in related domain make the technical solution of the utility model, all should fall in the definite protection domain of claims of the present utility model.
