Abstract
The utility model discloses a reel used for a rotary drilling rig. The reel comprises a reel body. A plurality of helical rope grooves is arranged at the periphery of the reel body. The last loop of the first layer of the rope grooves is provided with climbing stands that helically advance from the first layer to the second layer within a 180-degree area in a circumferential manner. Helical bar-shaped and band-shaped edge contours are disposed within a 180-degree area continuously helical along with the climbing stands at the periphery of the reel body. Through the above scheme, a steel rope winding mode is changed under a condition that the pitch diameter of reels is equal, such that steel ropes are wound to form the minimum expansion folding line angle, abnormal winding of steel ropes is prevented once severe abnormal winding conditions occur, and then the service life of steel ropes is prolonged. The reel used for a rotary drilling rig is further illustrated in combination with drawings and embodiments.
Description
Technical field
The utility model relates to a kind of rotary drilling rig winch, relates to specifically a kind of rotary drilling rig reel, belongs to rotary drilling rig technical field.
background technology
When rotary drilling rig work, promote, transfer drilling rod etc. by hoisting speed reducer, realize the circulation of fetching earth; Initial reel generally adopts circular helix reel, has steel rope disorder cable phenomenon, easily rope skipping, and it is less that steel rope forms broken line angle while intersecting break-in, and it is serious that steel rope is stung rope; Generally adopt at present dual slope reel, steel rope is disorder cable not, and owing to being generally made up of two sections of parallel liness and two sections of broken lines, steel rope broken line angle is generally no more than 90 degree, and steel rope ubiquity is stung rope phenomenon, causes steel rope short-term to damage.
As shown in Figure 1 and Figure 2, the grooving 4 of existing dual slope reel is generally interspersed by two section spiral line parts 1 and two sections of parallel lines parts 2.The spiral angle α of helix line part 1 is generally 35-90 degree, two section spiral line parts 1, ground floor circle 6 parts last are led platform part 5, another part for climbing platform part 3 for commutating, there is no the variation of pitch in climbing the grooving 4 of platform part 3, the every circle of reel is in the every part of helix line, and the p/2 that advances is apart from (p is steel rope pitch).
Steel rope Mei Cengpatai district, while climbing platform, steel rope does not have pitch variation, is subject to climbing the last circle impact of platform, and steel rope must be lifted to certain altitude, and the steel rope of raising and upper strata first lap easily form gap, affect upper strata row's rope.Due to the existence of parallel portion, wirerope-winding forms broken line angle after reel, can not be as far as possible little, sting rope more serious.
Summary of the invention
Problem to be solved in the utility model is to provide one can climb platform mode by improvement, under identical reel central diameter, change wirerope-winding mode, wirerope-winding is formed and launch broken line angle minimum, and then alleviate and sting rope, can improve the rotary drilling rig reel of stinging rope in the large situation of steel rope list rope tension.
In order to address the above problem, the utility model by the following technical solutions:
A kind of rotary drilling rig reel, comprise spool body, the excircle of described spool body is provided with the grooving of some roads helix line pattern, the ground floor circle last of described grooving has the platform of climbing going forward one by one to second layer spiral from ground floor at circumferential 180 degree in regions, on the excircle of spool body, has the banded edge of spiral line type bar shaped profile with climbing in the 180 degree regions that platform continues spiral mutually of going forward one by one to second layer spiral of this ground floor.
Steel rope passing through herein, realize steel rope and lower floor's steel rope reversing sense, while grooving is realized p/2 at the banded edge of this spiral line type bar shaped contour area guiding steel wire rope and is advanced, successively later, within the scope of each 180 degree, the steel rope p/2 distance of advancing, reel is wound around p/2 distances in each 180 regions.Multiple wraps mode is equal to upper type.
Below the further optimization of the utility model to such scheme:
The position of the outer end of the described ground floor positive number first lap near grooving is provided with the second layer grooving of 2-3 circle spiral, and second layer grooving has going forward one by one of going forward one by one to the 3rd helical layer from the second layer near a circle of spool body end and climbs platform in circumferential 180 degree regions.When second layer ending, ensure that by grooving steel rope is wound around according to predetermined, be two or three layers and realize similar one or two layers of winding guiding; Multiple wraps mode is equal to with upper type.
The utility model adopts such scheme, under identical reel central diameter, has changed change wirerope-winding mode, wirerope-winding is formed launch broken line angle minimum, can improve and sting rope stinging under the serious operating mode of rope, has extended service life of steel wire rope.Below in conjunction with drawings and Examples, the utility model is described in further detail.

In figure: 1-spiral part; 2-parallel portion; 3-climbs platform part; 4-grooving; Platform part is led in 5-commutation; 6-ground floor circle last; Alpha-helix angle; 7-spool body; The banded edge of 8-spiral line type bar shaped profile; What 9-ground floor went forward one by one to second layer spiral climbs platform; 10-ground floor positive number first lap; 11-second layer grooving; Platform is climbed in going forward one by one that the 12-second layer goes forward one by one to the 3rd helical layer.
detailed description of the invention
Embodiment, as Fig. 3, shown in Fig. 4, a kind of rotary drilling rig reel, comprise spool body 7, the excircle of described spool body 7 is provided with the grooving 4 of some roads helix line pattern, the ground floor circle 6 last of described grooving 4 circumferential 180 degree have in regions go forward one by one to second layer spiral from ground floor climb platform 9, on the excircle of spool body 7, climb with this 180 degree that platform continues spiral mutually and there is the banded edge of spiral line type bar shaped profile 8 in regions, steel rope passing through herein, realize steel rope and lower floor's steel rope reversing sense, while grooving is realized p/2 at the banded edge of this spiral line type bar shaped profile 8 regional guidance steel ropes and is advanced, successively later, within the scope of each 180 degree, the steel rope p/2 distance of advancing, be that reel is wound around p/2 distance in each 180 degree regions.Multiple wraps mode is equal to upper type.
The position of the outer end of the described ground floor positive number first lap 10 near grooving 4 is provided with the second layer grooving 11 of 2-3 circle spiral, and second layer grooving 11 has going forward one by one of going forward one by one to the 3rd helical layer from the second layer near a circle of spool body 7 ends and climbs platform 12 in circumferential 180 degree regions.When second layer ending, ensure that by grooving steel rope is wound around according to predetermined, be two or three layers and realize similar one or two layers of winding guiding; Multiple wraps mode is equal to with upper type.
The utility model adopts such scheme, and the theoretical broken line angle of reel minimum can be improved and sting rope, prolonging service life of steel wire stinging under the serious operating mode of rope; Reel do not having grooving part can make steel rope each 180 degree, with p/2 apart from ordered arrangement.There is no grooving part, spending the region p/2 that advances by guiding reel at every circle 180, every circle moves into p.
