Description
Technical field
The utility model is related to a kind of pulley structure, more particularly to a kind of rig high-altitude fixed pulley structure.
Background technology
Pulley is the indispensable part of drilling equipment, and conventional use of high-altitude fixed pulley is all to be equipped with bolt in pulley side to make
To keep off rope bar, but when steel wire rope is installed in high-altitude, it is necessary to which gear rope bar is unloaded, steel wire rope will keep off rope bar after installing and fills again again
On；In the process, bolt and its component easily drop, and not only cause inconvenience during installation, and there is falling object from high altitude to hurt sb.'s feelings
Potential safety hazard.
The content of the invention
The utility model provides a kind of rig high-altitude fixed pulley structure, using rotatable gear rope bar, can install steel
Rotated during cord to get out of the way installing space, steel wire rope playbacks rapidly after installing；Its is simple in construction, easy to use, and can avoid height
The potential safety hazard of sky pendant thing.
In order to achieve the above object, the utility model is realized using following technical scheme：
A kind of rig high-altitude fixed pulley structure, including the fixed pulley being made up of pulley, pulley bracket and pulley mount；
Also include rotatable gear rope bar；2 side plates of the pulley bracket install rotatable gear rope bar side protrude from pulley it
Outside, the ledge of one of side plate is provided with straight trough mouthful, and the ledge of another side plate is provided with square notch；Rotatably
Gear rope bar is be arranged in parallel with pulley axis, and its one end is fixed in straight trough mouthful and can rotated around bearing pin, the other end by bearing pin
Actively it is fastened in square notch.
It is welded and fixed between bearing pin and the pulley bracket side plate.
Sleeve is set in the middle part of the rotatable gear rope bar, sleeve can freely rotate rotatable gear rope bar around rotatable gear rope bar
The upper position on the inside of square notch, on the outside of sleeve sets fixed baffle ring, and the excircle diameter of fixed baffle ring is more than in sleeve
Footpath.
Compared with prior art, the beneficial effects of the utility model are：
With it is simple in construction, easy to use, be widely used, processing and manufacturing cost it is low, the features such as safe.
Brief description of the drawings
Fig. 1 is the front view of rig high-altitude described in the utility model fixed pulley structure.
Fig. 2 is Fig. 1 top view.
Fig. 3 is the A-A sectional views in Fig. 2.
In figure：1. the pulley mount 4. of 2. pulley of pulley bracket 3. rotatably consolidate by the sleeve 7. of 5. bearing pin of gear rope bar 6.
Determine baffle ring
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
As shown in Figure 1-Figure 3, a kind of rig high-altitude fixed pulley structure described in the utility model, including by pulley 2, pulley
The fixed pulley that support 1 and pulley mount 3 are constituted；Also include rotatable gear rope bar 4；2 side plates of the pulley bracket 1 exist
Rotatable gear rope bar 4 side is installed to protrude from outside pulley 2, the ledge of one of side plate is provided with straight trough mouthful, another
The ledge of side plate is provided with square notch；Rotatable gear rope bar 4 is set with the diameter parallel of pulley 2, and its one end passes through bearing pin 5
It is fixed in straight trough mouthful and can be rotated around bearing pin 5, the other end is actively fastened in square notch.
It is welded and fixed between bearing pin 5 and pulley bracket 1 side plate.
The rotatable middle part of gear rope bar 4 sets sleeve 6, and sleeve 6 can freely be rotated around rotatable gear rope bar 4, rotatably
It is located on gear rope bar 4 on the inside of square notch, the position in the outside of sleeve 6 sets fixed baffle ring 7, the excircle diameter of fixed baffle ring 7
More than the internal diameter of sleeve 6.
On the fixed pulley of high-altitude gear rope bar be solely subjected to steel wire rope horizontal direction swing power, the utility model be according to its by
A kind of rotatable gear rope bar that quickly can be removed and reset of power feature design, facilitates high-altitude to install steel wire rope.
The normal bar in use, rotatable gear is restricted, which is horizontal, is fixed on the rope traction side of pulley 2, can be to movement
In steel wire rope play a part of it is spacing and be oriented to.
Square notch on 1 one side plates of pulley bracket is by the horizontal notch and the vertical slots positioned at inner side positioned at outside
Mouth is formed by connecting, and vertical notch extends to the lower section of horizontal notch；, only need to be by square notch one when needing more change steel rope
The rotatable gear rope bar 4 of side is lifted upward, it is deviate from from vertical notch, then will rotatably keep off rope bar 4 overall around straight
Bearing pin 5 in notch rotates about 90 °, you can concede steel wire rope installing space.Steel wire rope is put into after the grooving on pulley 2, then
Rotatable gear rope bar 4 is rotated backward, its corresponding end is reattached in the vertical notch of square notch, you can to throw again
Enter work.Be not used only it is very convenient, and without detachable block, it is to avoid the potential safety hazard of falling object from high altitude.
It is described above, only the utility model preferably embodiment, but protection domain of the present utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model is disclosed, according to this practicality
New technical scheme and its design is subject to equivalent substitution or change, should all cover within protection domain of the present utility model.
