The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of pulley yoke, and this pulley yoke is arranged on the mast of rotary drilling rig.
Refer to Fig. 1 and Fig. 2, this pulley yoke comprises master winch pulley yoke 1, be articulated with the secondary elevator pulley yoke 2 on this master winch pulley yoke 1 and be hinged on the connecting panel 3 on this master winch pulley yoke 1, this connecting panel 3 is optionally connected to two diverse locations between this master winch pulley yoke 1 and this pair elevator pulley yoke 2, line L1 between line L22 between two secondary elevator pulleys 22 on this pair elevator pulley yoke 2 and two master winch pulleys 12 on this master winch pulley yoke 1 is paralleled, or make to form angle between the line L1 between the line L21 between two secondary elevator pulleys 22 on this pair elevator pulley yoke 2 and two master winch pulleys 12 on this master winch pulley yoke 1.Below the structure of this pulley yoke is elaborated.
This master winch pulley yoke 1 of the utility model embodiment comprises body 11, is arranged at the master winch pulley 12 at these body 11 two ends and is fixed on the Connection Block 13 on this body 11 rotationally.This body 11 is arranged at the mast top of rotary drilling rig, has the effect of supporting this master winch pulley 12.Master winch steel rope one end is connected with the main winch of rotary drilling rig, and walks around this master winch pulley 12, and the other end is connected with the drilling rod of rotary drilling rig.This Connection Block 13 is fixed on a side of this body 11, and this Connection Block 13 is for being hinged with this pair elevator pulley yoke 2.It should be noted that, this Connection Block 13 can be save, and this pair elevator pulley yoke 2 can carry out hinged with this master winch pulley yoke 1 by other means.The object that this Connection Block 13 is set on body 11 is to be convenient to form required angle between this pair elevator pulley yoke 2 and this master winch pulley yoke 1.
This pair elevator pulley yoke 2 comprises main body 21 and is arranged at rotationally the secondary elevator pulley 22 at these main body 21 two ends.This main body 21 is hinged on this Connection Block 13 by S. A. 131, and this main body 21 is for supporting this pair elevator pulley 22.In this main body 21, be provided with the first hinge-point 211 and the second hinge-point 212.This first hinge-point 211 and the second hinge-point 212 are for being optionally connected with this connecting panel 3, to adjust the angle between this pair elevator pulley yoke 2 and this master winch pulley yoke 1, can make this pair elevator pulley yoke 2 change between two operating angles with respect to this master winch pulley yoke 1.Secondary one end of hoisting rope and the secondary winch of rotary drilling rig are connected, and walk around this pair elevator pulley 22, and the other end is connected with the steel reinforcement cage of rotary drilling rig.
The quantity of this connecting panel 3 is one, and its one end is hinged on this master winch pulley yoke 1, and the other end can be hinged on this first hinge-point 211 or the second hinge-point 212 by the Connection Element such as bearing pin, bolt.In the time that this connecting panel 3 is connected with this first hinge-point 211, line L1 between line L22 between two secondary elevator pulleys 22 on this pair elevator pulley yoke 2 and two master winch pulleys 12 on this master winch pulley yoke 1 parallels, and walks around two secondary hoisting ropes on secondary elevator pulley 22 and walks around two master winch steel ropes on master winch pulley 12 and parallel.In the time that this connecting panel 3 is connected with this second hinge-point 212, between line L1 between line L21 between two secondary elevator pulleys 22 on this pair elevator pulley yoke 2 and two master winch pulleys 12 on this master winch pulley yoke 3, form angle, walk around two secondary hoisting ropes on secondary elevator pulley 22 and walk around between two master winch steel ropes on master winch pulley 12 and form angle.
In the time that rotary drilling rig need to be sling steel reinforcement cage, one end of this connecting panel 3 is connected with this second hinge-point 212.Like this, walk around two secondary hoisting ropes on secondary elevator pulley 22 and walk around shape between two master winch steel ropes on master winch pulley 12 and have a certain degree, mast is without inclination.Therefore, only have the weight of steel reinforcement cage to be carried in a side of rotary drilling rig, in background technology, the service condition of rotary drilling rig, be not easy to cause tumbling of rotary drilling rig, improve the stability of rotary drilling rig work.When rotary drilling rig is in walking, when travelling position, be connected one end of this connecting panel 3 with this first hinge-point 211.Like this, walk around two secondary hoisting ropes on secondary elevator pulley 22 and parallel with walking around two master winch steel ropes on master winch pulley 12, thereby reduced the width of this pulley yoke, be convenient to walking and the transportation of rotary drilling rig.
The structure of the structure of the pulley yoke of another embodiment of the utility model and the pulley yoke of above-described embodiment is roughly the same, difference is that the pulley yoke of another embodiment comprises two connecting panels, i.e. the first connecting panel and the second connecting panel, and hinge-point on secondary elevator pulley yoke 2 is only one, one end of this first connecting panel and this second connecting panel is connected on this master winch pulley yoke 1, and the other end is optionally connected with this hinge-point.In the time that this first connecting panel is connected with this hinge-point, line L1 between line L22 between two secondary elevator pulleys 22 on this pair elevator pulley yoke 2 and two master winch pulleys 12 on this master winch pulley yoke 1 parallels, and walks around two secondary hoisting ropes on secondary elevator pulley 12 and walks around two master winch steel ropes on master winch pulley 12 and parallel.In the time that this second connecting panel is connected with this hinge-point, between line L1 between line L21 between two secondary elevator pulleys 22 on this pair elevator pulley yoke 2 and two master winch pulleys 12 on this master winch pulley yoke 1, form angle, walk around two secondary hoisting ropes on secondary elevator pulley 22 and walk around between two master winch steel ropes on master winch pulley 12 and form angle.The advantage of the pulley yoke of the present embodiment is somewhat identical with the pulley yoke of previous embodiment, therefore do not repeat.
In above-mentioned two embodiment, because this pair elevator pulley yoke can interfere with this master winch pulley yoke in the process of rotating relative to this master winch pulley yoke, therefore, the angle between this pair elevator pulley yoke and this master winch pulley yoke is preferably acute angle.If actual construction need, the angle between this pair elevator pulley yoke and this master winch pulley yoke also can form obtuse angle, this just needs this pair elevator pulley yoke and this master winch pulley yoke not in same level.For example, more than this Connection Block being extended to this master winch pulley yoke, this pair elevator pulley yoke is hinged on this Connection Block and extends to part more than this master winch pulley yoke.
The utility model embodiment also provides a kind of rotary drilling rig, and this rotary drilling rig is provided with above-mentioned pulley yoke.
Because above-mentioned pulley yoke has above-mentioned technique effect, therefore, the rotary drilling rig that is provided with this pulley yoke also possesses corresponding technique effect, and its specific implementation process is similar to the above embodiments, does not hereby repeat.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
