Further, the two ends of the first fixing rod 141 are respectively connected with the first riser 115 and the second riser 116 which are oppositely arranged, and the two ends of the second fixing rod 142 are respectively connected with the third riser 125 and the fourth riser 126 which are oppositely arranged, so that in the process that the first rotating shaft 21 slides along the first sliding chute 111 and the third rotating shaft 23 slides along the second sliding chute 121, the two first supporting rods 17 cannot interfere with the first fixing rod 141, the second supporting rod 18 cannot interfere with the second fixing rod 142, the sliding amount of the first rotating shaft 21 along the first sliding chute 111 is further ensured, and the sliding amount of the third rotating shaft 23 along the second sliding chute 121 is ensured, so that the compression amount or the stretching amount of the first elastic member 15 and the second elastic member 16 meets the use requirement.

In a specific embodiment, a plurality of first elastic members 15 and second elastic members 16 are respectively disposed, the plurality of first elastic members 15 are arranged at intervals along the length direction X of the first rotating shaft 21, and the plurality of second elastic members 16 are arranged at intervals along the length direction X of the third rotating shaft 23.

In the process that the first rotating shaft 21 slides along the first sliding groove 111, the first rotating shaft 21 simultaneously compresses or stretches the plurality of first elastic pieces 15, in the process that the third rotating shaft 23 slides along the second sliding groove 121, the third rotating shaft 23 simultaneously compresses or stretches the plurality of second elastic pieces 16, so that elastic potential energy generated by the first elastic pieces 15 and the second elastic pieces 16 is increased, more kinetic energy of a pipe cleaner or a detector is consumed, and the blind plate is better protected. And the first elastic member 15 and the second elastic member 16 are respectively provided with a plurality of elastic members, if one of the first elastic member 15 or the second elastic member 16 is damaged, part of kinetic energy of the pipe cleaner or the detector can be consumed under the action of the other first elastic member 15 or the other second elastic member 16, so that the reliability of the ball receiving barrel buffer device is improved.

The first elastic member 15 may be a first spring, and two ends of the first spring are respectively provided with a first hook, wherein one first hook is clamped with the first fixing rod 141, and the other first hook is clamped with the first rotating shaft 21; the second elastic member 16 is a second spring, and two ends of the second spring are respectively provided with a second hook, wherein one second hook is clamped with the second fixing rod 142, and the other second hook is clamped with the third rotating shaft 23.

When the impact of the pig or the detector on the ball-receiving tube buffer is over, the blind is opened, and it is checked whether the first spring and the second spring are detached, rusted or otherwise irreversibly deformed, if so, the operator can detach the first spring or the second spring having a problem, and then replace the first spring with a normal one to be installed between the first fixing lever 141 and the first rotating shaft 21, or replace the second spring with a normal one to be installed between the second fixing lever 142 and the third rotating shaft 23.

Because the both ends of first spring are respectively through first trip and first dead lever 141 and first pivot 21 joint, operating personnel is convenient for carry out dismouting operation to first spring, and the both ends of second spring are respectively through second trip and second dead lever 142 and third pivot 23 joint, and operating personnel is convenient for carry out dismouting operation to the second spring, reduces on-the-spot operating personnel's work load by a wide margin.

In other embodiments, the first elastic member 15 and the second elastic member 16 may also be elastic cords.

In one embodiment, the interception plate 13, the first support bar 17 and the second support bar 18 are made of brass.

When the pipe cleaner or the detector moves towards the blind plate, the interception plate 13 is impacted by the pipe cleaner or the detector, the two ends of the first supporting rod 17 respectively rub against the first support 11 and the second support 12, the two ends of the second supporting rod 18 respectively rub against the first support 11 and the second support 12, friction is also generated between the first supporting rod 17 and the second supporting rod 18, and as the interception plate 13, the first supporting rod 17 and the second supporting rod 18 are respectively made of brass, no spark is generated when the parts of the brass are impacted or rubbed, so that the possibility of accidents caused by igniting inflammable substances in the ball collecting barrel by the spark is avoided, and the safety is improved.

To facilitate replacement of the interception plate 13, the interception plate 13 is detachably connected with the second bracket 12.

As the interception plate 13 is impacted by the pipe cleaner or the detector, the interception plate 13 is easy to deform or even damage with larger area along with the extension of the service time, so the interception plate 13 is convenient to replace due to the detachable connection of the interception plate 13 and the second bracket 12; but also different sized interception plates 13 can be exchanged to accommodate different types of pigs or detectors.

The specific implementation mode of the detachable connection of the interception plate 13 and the second bracket 12 can be that the interception plate is connected through bolts, or can be that the interception plate is clamped with the clamping holes through buckles.

In addition, when changing not unidimensional interception board 13, adjust the specification and the quantity of first spring and second spring, adapt to the demand of each number pig for the adaptability of receipts ball section of thick bamboo buffer is strong.
