In addition, the cross-sectional shape of the first barrier rib 4 and the second barrier rib 6 may be circular, rectangular, or the like. The connection between the first end 41 of the first bar 4 and the first end 31 of the sliding rod 3 may be a weld, a screw connection, etc. The shortest distance between the first sliding groove 122 and the side wall of the cylinder 5 is the distance between the groove wall of the first sliding groove 122 closest to the second end 12 of the body 1 and the side wall of the cylinder 5 farthest from the second end 12 of the body 1.

Finally, the metal washer 28 may be sized according to the inner diameter of the sleeve 27, as long as it is ensured that the metal washer 28 just fits inside the sleeve 27. Since the metal gasket 28 is convex and the edge of the metal gasket 28 contacts the bottom surface of the sleeve 27, the metal gasket 28 is higher than the bottom surface of the sleeve 27 except for the edge, which facilitates the vibration of the metal gasket 28. In practical applications, in order to make the metal gasket 28 vibrate more when the first end 61 of the second stop strip 6 impacts the metal gasket 28 after passing through the first through hole, the third through hole 124 and the fourth through hole 125, the radial dimension of the metal gasket 28 may be set to be smaller than the inner diameter of the sleeve 27.

In practical application, as shown in fig. 3, when a ball needs to be collected by the ball collecting device, the sliding rod 3 may be moved in the first sliding groove 122 and the second sliding groove toward the direction close to the second end 12 of the body 1, and then the first blocking strip 4 is driven to move toward the direction close to the second end 12 of the body 1 until the second end 42 of the first blocking strip 4 passes through the second through hole and then is located in the first through hole, and contacts or is about to contact with the inner wall of the cylinder 5 near the second end 12 of the body 1. The first end 61 of the second bar 6 is then positioned in the first through hole and between the second end 52 of the cylinder 5 and the second end 42 of the first bar 4, while the first bar 4 confines the second bar 6 in the upper space of the first through hole of the cylinder 5. And then, adjusting the orientation of the ball collecting device according to the current orientation of a cross bar arranged in the cross bar type pipe cleaner, and moving the ball collecting device to the direction close to the cross bar in the cross bar type pipe cleaner. When the ball collecting device moves to the position where the sliding rod 3 is in contact with the cross bar, the ball collecting device continues to move towards the inside of the cross bar type pipe cleaner, at the moment, the cross bar can push the sliding rod 3 to move towards the direction away from the second end 12 of the body 1 in the first sliding groove 122 and the second sliding groove, and then the first barrier strip 4 can be driven to move towards the direction away from the second end 12 of the body 1. When the second end 42 of the first bar 4 is moved out of the first through hole, the first end 61 of the second bar 6 is no longer located between the second end 52 of the drum 5 and the second end 42 of the first bar 4, and the second bar 6 passes through the first through hole, the third through hole 124 and the fourth through hole 125 under the action of gravity or the human-applied force. So, the whippletree in this whippletree formula pig is restricted in the space that the cell wall of first blend stop 4, second blend stop 6 and first recess 121 encloses, and the whippletree will not throw off with this receipts ball device to when removing this receipts ball device to the direction of keeping away from the pipeline at this whippletree formula pig place, because the whippletree can not throw off with this receipts ball device, consequently can pull out this whippletree formula pig from the pipeline smoothly, improved receipts ball efficiency.

Wherein, when the position of this receipts ball device is adjusted according to the current position of the whippletree that sets up in the whippletree formula pig, can be according to the current position of the whippletree that sets up in the whippletree formula pig, rotatory this receipts ball device for the angle of the contained angle between slide bar 3 and the whippletree in this receipts ball device is greater than preset the angle. The preset angle may be preset, for example, the preset angle may be 20 degrees, 30 degrees, 90 degrees, and the like, as long as it is ensured that when the ball collecting device is moved towards the inside of the bar type pig, the bar may contact the first blocking strip 4 and may push the first blocking strip 4 to move towards the direction away from the second end 12 of the body 1, which is not specifically limited in the embodiment of the present invention.

It should be noted that, since the length of the first barrier 4 is greater than or equal to the first length, and the first length is the sum of the shortest distance between the first sliding groove 122 and the side wall of the cylinder 5 and the diameter of the cylinder 5, the second end 42 of the first barrier 4 can pass through the second through hole and then be located in the first through hole, and at this time, the first barrier 4 can limit the position of the second barrier 6, so that the first end 61 of the second barrier 6 can be located between the second end 52 of the cylinder 5 and the second end 42 of the first barrier 4. And because the length of the first stop strip 4 is less than or equal to the second length, which is the sum of the shortest distance between the first sliding groove 122 and the side wall of the cylinder 5 and the length of the first sliding groove 122, the first stop strip 4 can be completely removed from the first through hole, at this time, the first stop strip 4 does not limit the position of the second stop strip 6, and thus, the second stop strip 6 can move towards the direction close to the fourth through hole 125 under the action of gravity or artificial force. And because the length of the second barrier strip 6 is greater than or equal to the radial dimension of the second end 12 of the body 1, the second barrier strip 6 can pass through the first through hole, the third through hole 124 and the fourth through hole 125 under the action of gravity or artificial force. So, the cell wall of first blend stop 4, second blend stop 6 and first recess 121 can form a spacing space for the whippletree that the restriction whippletree formula pig set up in. Finally, since the first end of the sleeve 27 is connected to the side wall of the body 1, the sleeve 27 is communicated with the fourth through hole 125, the convex metal gasket 28 is located in the sleeve 27, and the edge of the metal gasket 28 contacts the bottom surface of the sleeve 27, the first end 61 of the second stop strip 6 can strike the metal gasket 28 in the sleeve 27 after passing through the first through hole, the third through hole 124 and the fourth through hole 125. The metal gasket 28 vibrates under the impact of the first end 61 of the second stop strip 6 and then produces sound due to the vibration. In this way, when the technician is difficult to directly observe whether the first end 61 of the second barrier rib 6 has passed through the fourth through hole 125 due to reasons such as a weak light in the pipe where the horizontal bar pig is located, the technician can judge whether the first end 61 of the second barrier rib 6 has passed through the fourth through hole 125 by the sound emitted after the first end 61 of the second barrier rib 6 collides with the metal gasket 28, thereby helping the technician make an accurate judgment quickly. When the sound that sends after the technical staff hears the first end 61 of second blend stop 6 and metal shim 28 striking, just can confirm that the first end 61 of second blend stop 6 has passed fourth through-hole 125, then can confirm the whippletree that sets up in the whippletree formula pig has been restricted in first blend stop 4, in the spacing space that forms between the cell wall of second blend stop 6 and first recess 121, at this moment, the technical staff can stop to continue to remove to the intraductal removal at whippletree formula pig place with this receipts ball pig device to can avoid the mistake to promote whippletree formula pig in to the pipeline, ball efficiency is received further to the improvement.
