Abstract
The utility model relates to a sleeve detaching mechanism for a drilling rod. The sleeve detaching mechanism for the drilling rod comprises a gyrator, a main clamper, and the drilling rod fixed in the main clamper, wherein positioning frames are arranged on the two sides of the gyrator; a first sleeve component and a second sleeve component which are matched with each other are respectively erected on the two positioning frames; and the drilling rod is fixed between the first sleeve component and the second sleeve component. The sleeve detaching mechanism for the drilling rod is simple and reasonable in structure and small in space occupation; circumferential clamping force can be generated to the drilling rod, and the drilling rod is detached by utilizing the reverse rotation of the main clamper; additional labor does not need to be consumed; and therefore, the sleeve detaching mechanism for the drilling rod is convenient and effective.
Description
Technical field
The utility model relates to a kind of rig accessory, especially a kind of drilling rod pulling off sleeves mechanism.
Background technology
Because the space is narrow and small limited in the tunnel, colliery; Rig in the tunnel internal drilling can only select short drill pipe for use; This makes drilling rod dismounting increased frequency, and the dismounting tradition of drilling rod is to rely on pipe tongs to clamp the drilling rod manpower to dismantle, because of after the bore operation drilling rod receives very high pulling torque power; Connection becomes very tight, makes the drilling rod dismounting become very difficult.Also have on main clamper, to be equipped with and adopt another set of clamping device; Two clamping devices are launched simultaneously; Utilize the opposite spin of main clamper that drilling rod is dismantled again, this device often makes that becoming of rig is more huge, runs counter to the theory of operation in small space.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and effective, the simple in structure drilling rod easily of a kind of convenient disassembly pulling off sleeves mechanism is provided.
The utility model solves the technical scheme that its technical problem adopts: this drilling rod pulling off sleeves mechanism; Comprise gyrator, main clamper, be fixed in the drilling rod in the main clamper; The gyrator both sides are provided with locating rack; Set up the sleeve assembly one and sleeve assembly two of working in coordination respectively on two locating racks, be fixed with drilling rod between sleeve assembly one and the sleeve assembly two.
As preferably, sleeve assembly one front end is provided with front fork, and sleeve assembly two front ends are provided with and can be sheathed on the outer sleeve of front fork, and drilling rod is provided with holding tank, and sleeve assembly one is fixed drilling rod through the cooperation of front fork and holding tank.
As preferably, front fork is provided with alignment pin radially, is provided with annular slot in the sleeve, and sleeve ends is provided with the pin-and-hole that is communicated with annular slot.
As preferably, sleeve ends is evenly equipped with three pin-and-holes.
As preferably, sleeve assembly one is provided with the annular knurl reticulate pattern with sleeve assembly two surfaces.
The effect that utility model is useful is: the utility model is simple and reasonable, and it is little to take up room, and can produce the chucking power that makes progress in week to drilling rod, utilizes self rotating of main clamper, and drilling rod is dismantled, and need not extra labor intensive, easily and effectively.
Description of drawings
Fig. 1 is the assembly structure sketch map of the utility model;
Fig. 2 is the structural representation of sleeve assembly one;
Fig. 3 is the structural representation of sleeve assembly two;
Description of reference numerals: gyrator 1, main clamper 2, drilling rod 3, holding tank 31, locating rack 4, sleeve assembly 1, front fork 51, alignment pin 52, sleeve assembly 26, sleeve 61, annular slot 62, pin-and-hole 63, annular knurl reticulate pattern 7.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Embodiment: as shown in Figure 1; This drilling rod pulling off sleeves mechanism; Comprise gyrator 1, main clamper 2, be fixed in the drilling rod 3 in the main clamper 2; Gyrator 1 both sides are provided with sets up the sleeve assembly 1 and sleeve assembly 26 of working in coordination respectively on 4, two locating racks 4 of locating rack, be fixed with drilling rod 3 between sleeve assembly 1 and the sleeve assembly 26.
Like Fig. 2, shown in 3; Sleeve assembly one 5 front ends are provided with front fork 51; Front fork 51 is provided with alignment pin 52 radially, and sleeve assembly 26 front ends are provided with the sleeve 61 that can be sheathed on outside the front fork 51, are provided with annular slot 62 in the sleeve 61; Sleeve 61 ends are evenly equipped with three pin-and-holes 63 that are communicated with annular slot 62, and drilling rod 3 is provided with holding tank 31.Sleeve assembly 1 is provided with annular knurl reticulate pattern 7 with sleeve assembly 26 surfaces, increases frictional force, makes things convenient for the workman to operate.
During use, earlier the front fork 51 of sleeve assembly 1 is passed the holding tank 31 of drilling rod 3, the sleeve 61 with sleeve assembly 26 is sheathed on front fork 51 outsides again; Alignment pin 52 on the front fork 51 passes pin-and-hole 63 and gets into annular slot 62; Again sleeve assembly 26 is rotated slightly, make alignment pin 52 can not skid off from pin-and-hole 63, just fixed to one another and between sleeve assembly 1 and the sleeve assembly 26 with drilling rod 3 clampings; Again they are held on respectively on the locating rack 4, just can get into the duty of dismounting.Only need with main clamper 2 drilling rod 3 to be grasped again,, just can carry out dismounting it according to the screw thread installation direction counter-rotating between the drilling rod 3.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
