Description
Technical Field
The present invention relates to a construction machine, and particularly to a winding device for a fiber rope and a fiber rope winding method.
Background
The core components of the existing steel wire rope pre-tightening device comprise a middle winding drum, a braking device and the like, and mainly comprise the following components:
CN102040173B discloses a steel wire rope pre-tightening device, which has 2 parallel intermediate drums, a braking system, a force measuring device and a guide pulley; when the pre-tightening device works, the steel wire rope is wound on the pre-tightening winding drum, and the brake system provides resistance, so that the steel wire rope is wound on the target winding drum with the pre-tightening force.
CN204111228U discloses a pre-tightening device for a hoisting steel wire rope, which has a rope hoisting device, a pre-tightening torque applying device, a pulley, a hauling rope, etc., wherein the pre-tightening torque applying device acts on the pre-tightening hoisting device during operation, and a target winding drum overcomes resistance to wind the steel wire rope.
CN205151624U discloses a steel cable pre-tightening device, which has a winding drum, a braking device, a braking belt, etc.; the brake is a ratchet configuration that tensions the brake band to provide resistance.
CN201762048U discloses a wire rope pre-tightening and wire arranging mechanism of a winch, which comprises a wheel shaft, a winding drum, a torque motor, a meter counter, a speed reducer and the like; the resistance is provided by a torque motor.
Therefore, related industries in China have paid attention to the problem of installation of the pre-tightening force when the steel wire rope is wound at present, and relevant researches are carried out and the related technical schemes are published. When the steel wire rope is wound on the winding drum for the first time, the steel wire rope is prevented from extruding each other and increasing abrasion by applying proper pretightening force. And when using multilayer winding reel, upper rope arranges in the ditch groove that lower floor's rope formed, if lower floor's rope does not have the pretightning force, then lower floor's rope is easy to relax, can't form stable ditch groove, then upper rope is absorbed in the lower floor easily, causes the row rope confusion, seriously influences the life of rope.
However, the pre-tightening device of the existing hoisting mechanism is only designed for the steel wire rope, and does not consider the working characteristics of the fiber rope, namely, compared with the steel wire rope, the pre-tightening device has the characteristics of small friction coefficient, large stress deformation and the like. The existing steel wire rope pre-tightening device is directly used for the fiber rope, so that problems inevitably occur.
The friction coefficient of the fiber rope is small, so that the fiber rope is wound on the pre-tightening winding drum, the phenomenon that the fiber rope slips and the like can occur after loading, and the fiber rope cannot bear the required pre-tightening force; the deformation of the fiber rope is large after the fiber rope is loaded, the deflection angle during the winding process is not too large, otherwise, the quality of the winding rope is reduced, unnecessary abrasion is increased, and the fiber rope cannot be accurately wound into the rope groove of the winding drum.
In addition, the prior art applies the braking device on the pre-tightening winding drum instead of directly applying the braking device on the rope inlet end of the pre-tightening winding drum; the required braking force is large, so that the structure of the braking device is complex; since the fiber rope is light and soft, the tension at the rope inlet end of the pre-tightening drum is close to zero, and the expected effect cannot be produced only by applying the braking force to the pre-tightening drum.

The present invention provides a winding device for a fiber rope, as shown in fig. 1 to 3, comprising a fiber rope reel 10, a working reel 20, and an intermediate reel 30, wherein the fiber rope wound around the fiber rope reel 10 is wound around the working reel 20 via the intermediate reel 30, the fiber rope end side connected to the fiber rope reel 10 in the intermediate reel 30 is a rope inlet end side, and the fiber rope end side connected to the working reel 20 is a rope outlet end side.
In the present invention, the fiber rope reel 10, the work reel 20, and the intermediate reel 30 are rotated around their respective winding shafts. Preferably, the winding axis of the fiber rope reel 10, the winding axis of the working reel 20, and the winding axis 312 of the intermediate reel 30 are arranged in parallel.
The intermediate reel 30 includes: the rope clamping device 33 is arranged at the rope inlet end side of the middle winding drum 30 to apply rope clamping force to the fiber rope, the braking device 34 can apply braking force to the winding drum 31 to enable the winding drum 31 to rotate at a constant speed, and the surface of the winding drum 31 is arranged to enable the fiber rope to slide on the surface.
Specifically, according to the present invention, the rope clamping device 33 is disposed at the rope inlet end side of the intermediate winding drum 30, and the rope clamping device 33 applies a rope clamping force to the fiber rope, so that the characteristic of small friction coefficient of the fiber rope is fully considered, and the rope clamping device 33 can wind the fiber rope into the working winding drum 20 through the intermediate winding drum 30 with a large pre-tightening force of the fiber rope by only providing a small rope clamping force.
Specifically, the rope clamping device 33 can clamp the fiber rope 1 through two oppositely arranged pressing plates to compress the fiber rope, so as to generate friction resistance when the fiber rope is wound in; the acting force source of the rope clamping device can adopt a hydraulic or mechanical jack and the like.
On the basis of the above technical solution, the intermediate winding drum 30 further includes a braking device 34, and the braking device 34 can apply a braking force to the winding drum 31 to make the winding drum 31 rotate at a constant speed.
The brake device 34 can be mechanical, hydraulic, pneumatic, or the like. The brake device 34 includes, as an embodiment, a brake pad 342 capable of holding either one of the first stopper plate 313 and the second stopper plate 314, and a brake member capable of causing the brake pad 342 to apply a braking force F2And a pressing mechanism 341 for performing clamping.
On the basis of the above technical solution, the intermediate winding drum 30 further includes a drum limiting rail 32. The winding cylinder 31 includes a cylinder 311, winding shafts 312 projecting from the cylinder 311 toward both ends in the axial direction, and a first stopper plate 313 and a second stopper plate 314 projecting from the cylinder 311 at different positions in the axial direction. As a specific embodiment, as shown in fig. 1 to 3, first stopper plates 313 and 314 are provided on both end surfaces in the axial direction of the cylinder 311.
The first restriction plate 313 and the second restriction plate 314 form a winding space of the winding cylinder 31, and the length of the winding space is long enough to wind the fiber rope for a large number of turns, for example, 8 to 12 turns.
The winding shaft 312 is longer than the cylinder 311, is rotatably disposed in the cylinder stopper rail 32, and is movable along the cylinder stopper rail 32 relative to the work drum 20.
Compared with a steel wire rope, the fiber rope has small friction coefficient and large stress deformation, so that the fiber rope 1 deforms greatly after being stressed, the diameter of the cross section is reduced, and the radial extension is more. When the rope inlet end side of the working winding drum is positioned at the end part of the drum body, the deflection angle when the fiber rope winds in is large, so that the fiber rope is easily abraded, and the rope arrangement quality is influenced.
In contrast, in the present invention, the winding cylinder 31 is configured to be capable of moving relative to the working drum 20 along the axial direction, as shown in fig. 2, when the rope feeding end side of the working drum 20 is located at the lower end, the fiber rope pre-tightening force generates a downward component force in the axial direction of the winding cylinder 31, and the winding cylinder 31 slides downward under the component force, so that compared with the original position (shown by a dotted line) of the winding cylinder 31 in the figure, the declination angle of the fiber rope at the rope feeding position of the working drum is reduced after the winding cylinder 31 slides downward, thereby being beneficial to avoiding the abrasion of the fiber rope and improving the rope arranging quality.
In addition, when the intermediate winding drum 30 is configured to move relative to the operating winding drum 20, the braking device 34 further includes a slide rail capable of enabling the braking device 34 to move along with the winding drum 31, the slide rail is parallel to the winding shaft 312, so that the braking device 34 can slide along with the winding drum 31 in the axial direction, preferably, the length and the position of the slide rail are set corresponding to the drum limiting rail 32, and pressure is always applied to the intermediate winding drum 30 during the winding process, so that the intermediate winding drum 30 rotates at a constant speed.
On the basis of the above technical solution, the intermediate winding drum 30 further comprises a rotary encoder 35, and the rotary encoder 35 is disposed at one end of the winding shaft 312, for example, by a flexible coupling or the like. The rotational speed of the winding drum 31 can be measured by the rotary encoder 35 to calculate the length of the rope, and the winding shaft 312 can be ensured to normally operate even when it moves in the axial direction by the flexible coupling.
The work drum 20 includes a work cylinder 21 and a drive device 22 for rotating the work cylinder 21. The drive 22 rotates the working drum 21, so that the fiber rope on the fiber rope drum 10 is wound onto the working drum 20 via the intermediate drum 30 with a predetermined fiber rope tension.
The drum limiting rail 32 includes a first limiting rail 321 and a second limiting rail 322 respectively located at two axial sides of the drum 311, the first limiting rail 321 and the second limiting rail 322 are arranged in a manner that the winding shaft 312 is parallel to the winding shaft of the fiber rope drum 10, and the winding shaft of the fiber rope drum 10 is parallel to the winding shaft of the working drum 20.
The first and second limiting rails 321 and 322 are disposed corresponding to the winding space of the work roll 20. Through this mode of setting up, the in-process of advancing rope terminal side along axial reciprocating motion of work reel 20, the fiber rope pretightning force can stimulate the barrel 31 of convoluteing all the time along the spacing track reciprocating motion of barrel, makes the fiber rope can be convoluteed with the less mode of skew angle of relative work reel all the time, avoids the rope arranging confusion effectively.
Further, the surface of the winding drum 31 is provided so that the fiber rope can slide on the surface. The fiber rope 1 can slide on the whole surface of the barrel body without being blocked, so that the fiber rope 1 can slide on the whole surface of the barrel body, a continuous winding-in and winding-out state is formed, and stable winding is kept. Specifically, when the position of the rope inlet end side of the fiber rope 1 reaches the first limiting plate 313 or the second limiting plate 314 of the winding cylinder, the first limiting plate 313 or the second limiting plate 314 extrudes the fiber rope 1 to push the fiber rope 1 to slide on the surface of the cylinder along the axial direction, and as no groove or the like capable of blocking the sliding of the fiber rope exists on the surface of the cylinder, the middle winding drum 30 is not disturbed in the winding process, and the fiber rope is ensured to form a continuous winding-in and winding-out state on the cylinder. It is further preferred that the surface is a smooth surface having a coefficient of friction with the fibre rope 1 of less than 0.1, so that there is less slip of the fibre rope 1 between the surfaces of the cylinder.
In addition, the present invention also provides a rope fiber rope winding method of a winding device, comprising the preparation steps of respectively arranging a fiber rope reel 10, a working reel 20 and an intermediate reel 30 on which the fiber rope is wound; the free end of the fibre rope is fixed to the working drum 20 after a predetermined number of windings on the winding drum 31 of the intermediate drum 30 via the rope clamping device 33 of the intermediate drum 30.

Specifically, the stress situation of the fiber rope when the fiber rope is wound in and out on the winding drum 31 is shown in fig. 3, for example, the pre-tightening force of the fiber rope 1 can be changed according to the diameter, strength, working load and the like of the fiber rope, taking a high-performance fiber rope with a diameter of 22mm as an example, the breaking tension is 380KN, and the pre-tightening force can be 2% of the breaking tension, i.e. S27.6KN, F is 0.04, n is 10, and F is1＝1.014S2＝7.71KN。
Further, the adjusting step further comprises adjusting the braking device 34 of the intermediate reel 30 to apply a braking force to the winding cylinder 31Power F2The braking force F2Satisfies the following formula:wherein r is1Is the winding radius of the winding cylinder 31, r2The length of the arm of action of the braking device 34, μ is the coefficient of friction of the braking device 34 against the winding drum 31, wherein S1Satisfy the requirement ofIn addition, d1＝2r1，d2＝r2。
The pressure of the brake device is adjusted, so that the rotating speed of the winding drum 31 is adjusted, and the pre-tightening winding drum rotates at a constant speed. When r is2＝2r1Mu is 0.3, in this case, F2＝0.766S2＝5.82KN。
As can be seen from the above, with the fiber rope winding method of the present invention, only a small rope holding force F needs to be applied to the fiber rope1And a braking force F2Therefore, the rope clamping device 33 and the braking device 34 with simple structures can be easily realized.
