Description
Technical field
The utility model belongs to Oil-gas Long-distance Transportation Pipeline detection facility, especially relates to a kind of in-pipeline detector probe prepressing device.
Background technique
In prior art, the spring adopted in in-pipeline detector probe precompressed mechanism is special-shaped nonstandard spring, and limited by the technical merit of special-shaped nonstandard spring up till now, deformed spring permanent deformation can occur under long-term work state, probe can not be kept in the center, cause probe mechanism to lose efficacy.
Summary of the invention
In view of this, the utility model is intended to propose a kind of in-pipeline detector probe prepressing device, works long hours permanent deformation occurs under state and the problem that causes probe mechanism to lose efficacy to solve deformed spring in prior art.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of in-pipeline detector probe prepressing device, this device is by fixed base and equipment connection, comprise rotating shaft, fixed base, swing arm, probe, slave arm, adjusting nut, spring capping, spiral compression spring, spring pull bar, one end and the swing arm of described fixed base are linked together by rotating shaft, described swing arm and probe are linked together by rotating shaft, described probe and slave arm are linked together by rotating shaft, the other end of described slave arm and fixed base is linked together by rotating shaft, be provided with spiral compression spring in the circular hole that one end of described spring pull bar is fixed on fixed base bottom, spring capping and adjusting nut, the other end of described spring pull bar is linked together by rotating shaft and swing arm.
Relative to prior art, a kind of in-pipeline detector probe prepressing device described in the utility model has following advantage:
In the utility model, sonde configuration adopts parallelogram principle, and selected spring is cylindroid helicalcoil compression spring, this spring technology maturation, reliable performance, can overcome the quality problems of deformed spring in prior art, improves the reliability of mechanism.
Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is a kind of in-pipeline detector probe prepressing device described in the utility model embodiment;
Description of reference numerals:
1-rotating shaft, 2-fixed base, 3-swing arm, 4-pops one's head in, 5-slave arm, 6-adjusting nut, 7-spring capping, 8-spiral compression spring, 9-spring pull bar.
Embodiment
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
A kind of in-pipeline detector probe prepressing device, this device is by fixed base 2 and equipment connection, comprise rotating shaft 1, fixed base 2, swing arm 3, probe 4, slave arm 5, adjusting nut 6, spring capping 7, spiral compression spring 8, spring pull bar 9, one end and the swing arm 3 of described fixed base 2 are linked together by rotating shaft 1, described swing arm 3 and probe 4 are linked together by rotating shaft 1, described probe 4 and slave arm 5 are linked together by rotating shaft 1, the other end of described slave arm 5 and fixed base 2 is linked together by rotating shaft 1, be provided with spiral compression spring 8 in the circular hole that one end of described spring pull bar 9 is fixed on fixed base 2 bottom, spring capping 7 and adjusting nut 6, the other end of described spring pull bar 9 is linked together by rotating shaft 1 and swing arm 3.
Working procedure of the present utility model is, probe 4 is under external force to pressing down, swing arm 3 is driven to rotate around corresponding rotating shaft 1, the swing arm 3 rotated drives spring pull bar 9 horizontal motion, due to the effect of spiral compression spring 8, when External Force Acting disappears, spring pull bar 9 pops into position to be put, drive swing arm 3 to sway simultaneously, thus probe 4 is kept in the center put.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
