Fig. 3 and 4 show the structure and shape of the flail alone, and fig. 1 and 2 show the application of the flail, which constitutes the mechanism for slow recovery of the pipe coiler.

As shown in fig. 3 and 4, the slinger 1 is an integrally formed part and has a base 11 and two friction blocks 12. Two friction blocks 12 are disposed around the base 11. In fig. 3 and 4, the two friction blocks 12 are rotationally symmetrical, and therefore, only the structure, function, and the like of one friction block will be described. The friction block 12 has a third end 123 and a fourth end 124 and a friction face 125 located between the third end 123 and the fourth end 124. The base 11 is provided with a base end connecting part 111 and a free end connecting part 112 at different positions in the circumferential direction of the base 11 corresponding to the respective friction blocks 12, the third end 123 and the base end connecting part 111 of the friction block 12 are integrally connected by an elastic swing arm 13, and the fourth end 124 and the free end connecting part 112 are integrally connected by an elastic tension member 14. The other friction block 12 will have its base end connection 111 and free end connection 112 reversed.

The elastic swing arm 13 is arranged to elastically deform under the action of the centrifugal force of the friction block 12 to drive the friction block 12 to swing outwards, the deformation direction of the elastic tension piece 14 is consistent with the swing direction of the friction block 12 swinging outwards, so the swing resistance to the friction block 12 can be almost ignored, but if the friction block 12 swings irregularly due to the overlarge rotating speed of the swinging block 1, the elastic tension piece 14 limits the swing in the non-deformation direction, and only allows the swing in the deformation direction to continue, so that the swing of the friction block 12 is allowed while the set swing direction of the friction block 12 is maintained. The set swing direction is a direction of swinging the circumferential side wall 21 to face the friction surface 125 described later.

Since the flail block 1 is an integrally formed part, the structure can be simplified compared to the prior art mentioned in the background section, and the flail block 1 can be formed by injection molding of plastic material. In addition, the cooperation of elasticity swing arm 13 and elastic tension spare 14 can effectively restrict the axial swing of clutch blocks 12, and the luffing motion in figure 4 keeps throwing piece 1 working property stable, plays stabilizing effect in the pipe recovery process.

With continued reference to fig. 3 and 4, the friction blocks 12 and the structure of the elastic swing arm 13 and the elastic tension member 14 corresponding to each friction block 12 are disposed along the base 11 in a rotational symmetry manner.

As shown in fig. 3, the swinging block only comprises two friction blocks 12, and the base 11 is in a straight shape. The arrangement structure is simple, and can provide enough buffering force in a small space to achieve the effect of slow recovery.

As shown in fig. 3 and 4, the elastic swing arm 13 and the friction block 12 extend along the rotation direction of the swinging block 1. So set up, the cantilever structure that elasticity swing arm 13 and friction block 12 formed will have the biggest cantilever length, consequently can set up the friction surface on bigger space, forms bigger cushioning effect.

The U-shaped elastic sheet has a simple structure, the deformation direction of the U-shaped elastic sheet is stable, certain rigidity can be formed in the non-deformation direction, and the axial swing of the friction block 12 is limited.

As shown in fig. 3 and 4, the elastic swing arm 13 has a flat arm 131 extending in an arc shape and a vertical arm 130 extending in an arc shape, and the flat arm 131 and the vertical arm 130 intersect perpendicularly in the longitudinal direction of the elastic swing arm 13. The flat arm 131 and the upright arm 130 intersect perpendicularly to each other and reinforce each other, i.e. allow the elastic swing arm 13 to have sufficient elasticity to swing, and on the other hand, can prolong the service life of the elastic swing arm 13 by functioning as a reinforcing rib to each other.

As shown in fig. 3 and 4, the base 11 has a transmission member 112 at the center of the swing block rotation, and the transmission member 112 is used for receiving the rotation transmitted by the pipe rolling device. The transmission member 112 is shown as a gear in the figures.

Fig. 1 and 2 show a mechanism for slow recovery of a pipe coiling device, which comprises a shell 2, wherein the shell 2 is provided with a central mounting part 20 and a surrounding side wall 21, the mechanism further comprises a swinging block 1, a base 11 of the swinging block 1 is in pivot connection with the central mounting part 20, a friction surface 125 of a friction block 12 of the swinging block 1 is arranged opposite to the inner circumferential surface of the surrounding side wall 21, and when the swinging block 1 reaches a set rotating speed, the friction surface 125 is in contact with the surrounding side wall 21 to form friction, so that the buffering or slow recovery effect is provided.

With reference to fig. 1 and 2, the mechanism further comprises a ring cover 3, the ring cover 3 being attached to the open side of the circumscribing sidewall 21 into which the flail 1 fits to limit axial movement of the flail 1. The housing 2 is fixed to the roller tube housing 4, or the housing 2 may be integrally formed with the roller tube housing 4.

Referring to fig. 1 and 2, a plurality of grooves 22 are circumferentially distributed on the inner wall surface of the surrounding side wall 21, a plurality of protrusions 32 are circumferentially distributed on the ring cover 3, and the plurality of protrusions 32 are respectively embedded in the plurality of grooves 22; the periphery of the surrounding side wall 21 is also convexly provided with a plurality of hole seats 23, the plurality of fasteners 5 are respectively screwed into the plurality of hole seats 23, and the heads of the fasteners 5 press the ring cover 3, so as to limit the axial displacement of the ring cover 3.

As shown in fig. 5, the swinging block 1 can rotate along a clockwise direction R1 or a counterclockwise direction R2, and when rotating along the clockwise direction, the friction block 12 is swung out, thereby playing a role of buffering, and the direction is also the furling direction of the reeler.

The foregoing embodiment has the following advantages:

the functional stability of the mechanism for slow recovery of the pipe coiling device is improved; when the throwing block 1 rotates at a high speed along with the furled pipe, the two friction blocks 12 have the tendency of axial swinging, the rotating speed of the throwing block 1 is faster, the swinging is more obvious, the amplitude is larger, the uncontrollable performance is increased, the swinging amplitude can be reduced under the action of the elastic tension piece 14, the stable working performance is ensured, and the pipe recovery process plays a role stably.

The minimum effective working revolution is improved; when the mechanism that the reelpipe ware was retrieved slowly worked, it is rotatory to get rid of piece 1, and clutch blocks 12 is toward outer swing, receives the effect of elastic tension spare 14, and when only the rotational speed that gets rid of piece 1 reached a great numerical value, clutch blocks 12 could be with the inner wall contact of encirclement lateral wall 21, produces frictional force, begins effective work.

The working life of a mechanism for slowly recovering the pipe coiling device is prolonged; when the pipe of the pipe coiling device is pulled out, the rotation speed of the throwing block 1 is slow, the centrifugal force is small, under the action of the elastic tension piece 14, the outward swinging amplitude of the two friction blocks 12 is small, the contact area with the inner wall of the encircling side wall 21 is reduced, and small friction force or no friction force is generated, which is equivalent to that a slow recovery mechanism does not work or works very little; the mechanism acts when the pipe is recovered and works normally; thus, the service life of the recovery buffer device is nearly doubled compared with the common recovery buffer device with a similar structure.
