Abstract

The utility model discloses a steel wire rope guide device of a winding engine, which comprises a pulley support (5) and a tilting mechanism (1). The pulley support (5) is connected with the tilting mechanism (1) through a slewing mechanism. The slewing mechanism is that a slewing block (3) is fixedly arranged at the bottom end of the pulley support (5), a conical surface hole (7) is axially arranged in the center of the slewing block (3), a spherical surface end (8) is arranged at one end of a supporting axle (2), the spherical surface end (8) of the supporting axle (2) is penetrated in the conical surface hole (7), and the other end of the supporting axle (2) is fixedly connected onto the tilting mechanism (1). The service life of a steel wire rope is long, and the steel wire rope guide device of the winding engine is simple in structure and low in manufacture cost.

Description

The winch wire line guide
Technical field
The utility model relates to a kind of wire line guide, is specifically related to a kind of winch wire line guide that is used for big rotary drilling rig.
Background technology
Rotary drilling rig is that China recent years is introduced one of piling machinery that develops, and is mainly used in the especially big bridge pier of various express highways, railroad bridge, and the special construction load-bearing foundation pile of other heavy constructions, is main pile foundation pore-forming instrument.Rotary drilling rig is because to have power big, and penetration rate is fast, characteristics such as degree of automation is high, the boring bore is big, accurate positioning, work efficiency height, and the advantage in construction is more and more outstanding.
At present, the pulley bracket of leading sheave that is applied to the big rotary drilling rig of engineering mostly adopts and is connected with simple swinging gear, and pulley bracket is followed steel rope and swung, thereby realization reduces the purpose of steel rope elevation angle.But in real work, the angle when simple swing does not enough realize steel rope turnover pulley reaches requirement.A kind of pulley bracket, turning gear, swinging mounting, board component down of comprising arranged in addition,, drive pulley bracket and swing and reduce elevation angle along with steel rope through turning gear, but this complex structure, and manufacturing cost is too high.
When the drift angle of rope race is excessive because steel rope is come in and gone out (>5 °), the grooving sidewall will receive the effect of big transverse force, and notch is damaged, and make steel rope take off groove.
The utility model content
The utility model technical matters to be solved provides a kind of winch wire line guide of long service life of steel rope.
In order to solve the problems of the technologies described above, the winch wire line guide that the utility model provides comprises pulley bracket and swinging gear, and described pulley bracket is connected with described swinging gear through rotating mechanism.
Described rotating mechanism is to be fixed with swivel block in the bottom of described pulley bracket; The center of described swivel block is axially arranged with conical surface hole; One end of bolster is provided with the sphere end; The sphere end of described bolster is through in the described conical surface hole, and the other end of described bolster is fixedly connected on the described swinging gear.
Described pulley bracket is provided with positioning plate.
Adopt the winch wire line guide of technique scheme, pulley bracket is connected with swinging gear through rotating mechanism, and swinging gear is directly installed on the mast.Wherein rotating mechanism adopts a swivel block to be connected with pulley bracket, and a pivot shaft is connected with swinging gear, and the sphere end through bolster contacts realization and rotates flexibly with the line in the conical surface hole of swivel block.And swinging gear is directly installed on the mast, and the arm of force of the swing that extended makes that this device swing is more flexible.Like this, when steel rope is in different rope stretching positions,, make pulley bracket along with steel rope is swung through the combined action of rotating mechanism and swinging gear.
The utility model is simple in structure; Low cost of manufacture; Can realize that leading sheave passes through steel rope turnover state automatic compensation, let leading sheave, avoid steel rope bigger elevation angle to occur through rotating flexibly and swing reduces the steel rope drift angle of coming in and going out; Reduce the wearing and tearing of steel rope, increased the service life of steel rope.
In sum, the utility model is a kind of long service life and winch wire line guide simple in structure, low cost of manufacture of steel rope.
Description of drawings
Fig. 1 is the front view of present embodiment.
B-B view embodiment illustrated in fig. 2.
Among the figure:
1. swinging gear, 2. bolster, 3. swivel block, 4. positioning plate, 5. pulley bracket.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
Referring to Fig. 1 and Fig. 2, the upper end of pulley bracket 5 is equipped with leading sheave 6, is fixed with swivel block 3 in the bottom of pulley bracket 5; The center of swivel block 3 is axially arranged with conical surface hole 7; One end of bolster 2 is provided with sphere end 8, and the sphere end 8 of bolster 2 is through in the conical surface hole 7, and the other end of bolster 2 is fixed on the swinging gear 1 through the nut that is welded on the swinging gear 1; Swinging gear 1 is connected with base 10 on being welded on mast through swinging mounting axle 9, and pulley bracket 5 is provided with positioning plate 4.
Referring to Fig. 1 and Fig. 2, during rotary drilling rig work, steel rope produces 2 rotations of transverse force driven rotary piece, swinging gear 1 swing through leading sheave 6, thereby makes pulley bracket 5 along with the steel rope swing.Wherein positioning plate 4 can prevent that guide pulley rack anglec of rotation under off working state is excessive.
