A kind of petroleum pipeline pigging equipment, including damping head 3, preceding pipe cleaner 1 and rear pipe cleaner 2, the preceding washer and It is encircled into the cavity 4 for accommodating cleansing medium between washer with the tube wall of pipeline afterwards, and the size of cavity 4 can be with cleaning The velocity variations of operation of the equipment in pipeline and change, such as preceding washer meets with obstruction decelerations, then after washer in rear pressure Washer is drawn close forward under the promotion of power, and 4 volume of cavity reduces the cleansing medium inside squeezing at this time, when pigging equipment is restored just The normal speed of service, preceding washer increase the distance between two washers (1,2).

The damping head 3 includes the columned damping portion 32 that cone head part 31 and cone head part 31 extend back；Before described Pipe cleaner 1 includes forward support post 11, and the 11 tail portion interval of forward support post is installed with multiple leather cups 5, the forward support post 11 Front is equipped with the interconnecting piece 111 that can be connect with damping head 3；Washer includes 21 tail of rear support strut 21 and rear support strut after described The fixed multiple leather cups 5 in portion interval, rear support portion front end are equipped with for 4 size of cavity between two washers (1,2) For storing the storage chamber of cleansing medium when variation；11 rear end of forward support post extends back top brace part 112, described to shore Portion 112 can be resisted against 21 front end of rear support strut, with when pigging equipment meets with obstruction or caliber becomes smaller, front and back washer is mutually leaned on Closely, but between the two the cavity 4 for accommodating cleansing medium out can still be retained, it will not be due to the distance between two washers (1,2) It is too small that cleansing medium is caused to leak, influence subsequent pigging operation.

The space size of the storage chamber 22 is variable, and the rear support strut 21 is provided with blind hole, is equipped with push plate in the blind hole 23 and storage spring 24 that push plate 23 can be pushed to move out, the storage chamber 22 be that the side wall of blind hole is surrounded with push plate 23 Space, when two washers (1,2) are mutually drawn close, cleansing medium, which is under pressure, pushes push plate 23 into blind hole, storage chamber 22 become larger, and cleansing medium enters in storage chamber 22, and when two washers (1,2) restore former motion state, storage spring 24 is pushed Push plate 23 moves out, and cleansing medium is released memory space, into cavity 4.

3 side wall of damping head is equipped with multiple rib bodies 35 that can abolish barrier along its length, and the rib body 35 is cut Face is triangle, and cone head part 31 is identical with 35 section of rib body of damping portion 32.

The damping portion 32 of the damping head 3 is provided with shock relieve vent 321,111 energy of interconnecting piece of the forward support post 11 along axial direction It is inserted into shock relieve vent 321, the damping portion 32 is in 321 weeks lateral edge Zhou Kaiyou annular grooves 322 of shock relieve vent, and the interconnecting piece 111 is along week It extends outward for preventing gear oil unit that is that pipeline residual object in leather cup 5 flows back and being protected to shock relieve vent and interconnecting piece 12, the oil unit 12 that keeps off includes the oil baffle 121 that can be inserted into annular groove 322, and connection oil baffle 121 and forward support post 11 Deflector 122, the deflector 122 extends outward the oily flange 123 of gear, the oil baffle close to one end of oil baffle 121 121 extend back water conservancy diversion flange 124 close to one end of deflector 122 outward, for prevent in pipeline remaining crude oil or its He flows into shock relieve vent 321 in gap of the impurity between damping head 3 and forward support post 11, influences the work of damping spring 33,

The interconnecting piece 111 is equipped with fixture block along week, and 321 inner sidewall of shock relieve vent is provided with card slot, the preceding washer and damping It is connected by card slot with fixture block between first 3, and the fixture block can move in card slot along 3 length direction of damping head.

Damping spring 33, and 11 end of forward support post and shock relieve vent are equipped between the forward support post 11 and damping portion 32 321 bottom hole is provided with location hole of the spring 34, and shock relieve vent 321 and forward support post 11 are inserted into the both ends of the damping spring 33 respectively Location hole of the spring 34 in.

32 maximum gauge of damping portion is equal with two washers (1,2) maximum gauge.

5 interference of each leather cup is sheathed on support column, and the damping head 3 and support column are existing and ability The common flexible material in domain, details are not described herein for device materials.

23 edge of push plate and the inner wall of blind hole are slidingly sealed by the formation of sealing ring (not shown).

During the work time, pigging equipment enters in oil pipeline, and damping head 3 utilizes the original of 35 extrusion pipe inner wall of rib body Oil makes the crude oil being attached on tube wall or iron rust be subjected to displacement or even fall off, and makes leather cup 5 be easier to clear up residue, works as pigging When equipment meets with obstruction or caliber narrows, obstruction or tube wall cause to impact to damping head 3, and impulse force is made by damping spring 33 Preceding pipe cleaner 1 gradually slows down, and pressure is formed to the cleansing medium in cavity 4, so that the cleansing medium in cavity 4 enters storage chamber Interior, when top brace part 112 and rear support strut 21 are to when supporting, cavity 4 is contracted to minimum volume, the skin of preceding washer and rear washer There is part cleaning solution between bowl 5, tube wall can still be cleaned, when pigging equipment spends narrow pipe path portion, push plate 23 is being stored It moves out under the action of spring 24, so that the cleansing medium in storage chamber 22 enters in cavity 4, tube wall is cleaned, and In the process, it is moved backward after the residue of tube wall is squeezed by rib body along oil baffle, when current washer stress is slowed down, gear Oiled-plate method is moved by inertia into annular groove, while the residue previous movement in leather cup, since deflector and the oily flange of gear are blocked Gap between the annular groove and oil baffle of damping head influences damping so that the residue in its leather cup will not enter in damping head Spring works.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
