Description
Technical field
The present invention relates to engineering machinery field, be specifically related to a kind of rotary drilling rig and rope limiting device thereof.
Background technology
In recent years, along with the construction energetically of the Infrastructure such as China's express highway, high speed railway, rotary drilling rig is developed rapidly and widespread use.But, still exist variety of issue for some types more ripe in rotary drilling rig, such as, because master winch is on lower mast, steel wire action radius is difficult to effective restriction, causes the steel rope oil cylinder that scratches frequently.Between master winch steel rope and mast, adding steel wire rope limiter is necessary to avoid steel rope to rock scratch oil cylinder.If it is spacing to utilize traditional fixed pulley to carry out steel rope, in the time that lengthening, fixed pulley causes normally movable mast of mast, and in the time that fixed pulley is short and small, cause master winch steel rope to be difficult to normal work.
Summary of the invention
In order to overcome above-mentioned defect and the deficiency of prior art, the first object of the present invention is to provide a kind of rope limiting device of the rotary drilling rig that does not affect movable mast and the normal work of rope, comprising: rope attaching parts; Springing, faces ectocentral position on the first end of springing and oil cylinder adapter shaft and is rotatably connected, and the second end is connected with rope attaching parts.
In order to overcome above-mentioned defect and the deficiency of prior art, the second object of the present invention is to provide a kind of rope limiting device of the rotary drilling rig that does not affect movable mast and the normal work of rope, comprising: rope attaching parts; The first springing and the second springing, the first end of the first end of the first springing and the second springing between the cylinder support at oil cylinder adapter shaft two ends, and respectively with oil cylinder adapter shaft on close on two ends cylinder support position be rotatably connected; The equal connecting rope attaching parts of the second end of the second end of the first springing and the second springing.
In order to overcome above-mentioned defect and the deficiency of prior art, the 3rd object of the present invention is to provide a kind of rotary drilling rig that does not affect movable mast and the normal work of rope, comprising: oil cylinder adapter shaft, the cylinder support that is positioned at oil cylinder adapter shaft two ends and above-mentioned rope limiting device.
The present invention is by the springing being rotatably connected with oil cylinder adapter shaft, and the residing position of this springing, has realized master winch rope away from oil cylinder, avoids the rope oil cylinder that frequently scratches, and guarantees that normal movable mast and rope normally work simultaneously.
Accompanying drawing explanation
Figure 1 shows that the structural representation of the rope limiting device embodiment mono-of rotary drilling rig of the present invention;
Figure 2 shows that the structural representation of the rope limiting device embodiment bis-of rotary drilling rig of the present invention;
Figure 3 shows that the structural representation of the rope limiting device embodiment tri-of rotary drilling rig of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, the rope limiting device embodiment mono-of rotary drilling rig of the present invention comprises: oil cylinder adapter shaft 2, two spacing rings 3, slip ring 4, spring 5, steel wire loop 7; Wherein, spring 5 is connected with steel wire loop 7, and by slip ring 4 and oil cylinder adapter shaft 2 slidably and be rotatably connected; Two spacing rings 3 are symmetricly set on the both sides of slip ring 4, for limiting the midway location of this slip ring 4 between two oil cylinder otic placodes 1, have realized to a certain extent two oil cylinders 6 of steel rope away from oil cylinder adapter shaft 2 two ends.
Under master winch normal working, steel rope is under the restriction of the spring 5 being connected with steel wire loop 7, can arbitrarily not swing, two oil cylinders 6 of steel rope away from oil cylinder adapter shaft 2 two ends are further realized, and master winch steel rope is in tensioning state, because spring 5 is that elastic body can, to the certain freedom of steel rope, not interfere master winch steel rope normally to be worked yet; In the situation of movable mast, because spring 5 is soft objects, and slip ring 4 is rotating movable members, therefore can not affect the normal movable mast of mast plate 8.
As shown in Figure 2, steel wire loop 7 can be other rope attaching parts, as wire rope pulley group 9, it will be understood by those skilled in the art that in the time that the rope of master winch adopts other materials, does not affect the structure of the rope attaching parts being connected with spring 5; When concrete operations, spring 5 can be set to be rotatably connected with oil cylinder adapter shaft 2, and not there is the function of slip, spacing ring 3 now can be set; Slip ring 4 can also be set to travelling of other sliding pairs, as slide rail; Spacing ring 3 is not defined as the structure of ring, as being limiting stopper; Spring 5 can be other elastomeric element, as elastoplast etc.
As shown in Figure 3, the rope limiting device embodiment tri-of rotary drilling rig of the present invention comprises: oil cylinder adapter shaft 2, two spacing rings 3, two slip rings 4, two spring 5(are hereinafter to be referred as left and right spring), steel wire loop 7; Wherein, two springs 5 are all connected with steel wire loop 7, and respectively by two slip rings 4 and oil cylinder adapter shaft 2 slidably and be rotatably connected; Spacing ring 3 on the left side springs 5 close on setting away from a side of oil cylinder otic placode 1, and another spacing ring 3 on the right spring 5 closes on setting away from a side of oil cylinder otic placode 1.
In the time that steel rope is offset to left side oil cylinder, the right spring 5 applies pulling force to it, and in like manner, in the time that steel rope is offset to the right oil cylinder, left side spring 5 applies pulling force to it, has realized to a certain extent two oil cylinders 6 of steel rope away from oil cylinder adapter shaft 2 two ends; Meanwhile, the position-limiting action of limit, left and right spring 5 under master winch normal working, has further avoided two oil cylinders 6 of steel rope near oil cylinder adapter shaft 2 two ends.
It will be understood by those skilled in the art that, corresponding to explaining in Fig. 2, Fig. 3 has equal alternative; The thickness of spring 5 and length can be adjusted with the need; Quantity, form, size and the installation site of spacing ring 3 can change according to the actual requirements; The each embodiment of rope limiting device of the present invention can be applied in various engineering machinery, is not limited to rotary drilling rig.
Various embodiments of the present invention provide a kind of scalability inhibiting device by the mating reaction of spring 5 and spacing ring 3 etc., effectively spacing to master winch steel rope, prevent master winch steel rope from arbitrarily swinging and on the basis of scratch oil cylinder, guarantee that rotary drilling rig is not subject to the normal movable mast of impact of inhibiting device, guarantee to give master winch steel rope certain degree of freedom under master winch steel rope normal working simultaneously, do not interfere steel rope normally to be worked; Meanwhile, the mating reaction of each slip ring 4, can effectively avoid, in steel cable sliding process, it is produced to undue wear; In addition, the scalability inhibiting device in each embodiment, simple in structure, and with low cost.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
