The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, a kind of power rat hole device, form by two power rat holes 2 that are arranged on the rig floor 1, wherein radius R is the radius of gyration of manipulator of making up a joint, two power rat holes 2 are arranged on the circular arc that radius is R, like this, make the drilling rod that manipulator just picks up on the cat road that makes up a joint be put in the rat hole.
As shown in Figure 2, described power rat hole 2 comprises cylindrical tube 3, promote guiding device 4, assembly pulley 5 and mobile buffer 6, described cylindrical tube 3 is equivalent to frame, be connected with the rig floor face, described cylindrical tube 3 comprises that pipe A3a and pipe B3b connect to form, the top of described pipe A3a is tapered opening, being convenient to drilling rod turnover and dirt flows out smoothly, be provided with hanger 19 in pipe A3a upper end, install and dismantle so that the power rat hole is sling with crane, the lower end of pipe A3a is connected by the upper end of adpting flange with pipe B3b, as shown in Figure 5, be provided with gathering sill 8 in described pipe B3b, be used to promote the guiding of guiding device 4 and mobile buffer 6, the bottom of described pipe B3b is connected with blow-off connection 18 by adpting flange.
Wherein, described assembly pulley 5 comprises running block 5a and fixed pulley group 5b, is provided with two movable pulley among the described running block 5a, is provided with two fixed pulleys among the described fixed pulley group 5b, described two movable pulley are arranged at and promote on the guiding device 4, and described two fixed pulleys are arranged at pipe A3a outer wall.
Described lifting guiding device 4 slidably is arranged on the pipe B3b outer wall, described lifting guiding device 4 is connected with hydraulic lifting oil cylinder 7, as shown in Figure 4, described lifting guiding device 4 comprises base 15, described base 15 is connected to form by symmetrical two parts and is wrapped in pipe B3b outer wall, between described base 15 and pipe B3b, be provided with directive wheel 17, move up and down along the guide rail of pipe B3b so that promote guiding device 4; Described two movable pulley are arranged at respectively on left and right sides two parts of base 15, and the piston of described hydraulic lifting oil cylinder 7 is connected with connector 16 on the base 15.
Described mobile buffer 6 slidably is arranged in the pipe B3b internal cavity, as shown in Figure 3, described mobile buffer 6 comprises pedestal 9, elastomeric element 10 and conical head 11, described elastomeric element 10 is a spring, the one end is connected with pedestal 9, the other end is connected with conical head 11, and spring is used to cushion the impact that brings when drilling rod falls; Described pedestal 9 be provided with pipe B3b in the base rail 12 of gathering sill 8 coupling, be convenient to mobile buffer 6 and in pipe B3b, move up and down, prevent that simultaneously it from rocking and rotate; In described conical head 11, be provided with rubber pad 14, be used to protect tool joint; Steel wire cable one end in the described assembly pulley 5 is fixed, the other end walks around respectively that the earrings 13 on the pedestal 9 is connected in running block 5a and fixed pulley group 5b and the described mobile buffer 6, by controlling moving up and down of mobile buffer, thereby the drilling rod of drive rat hole the inside moves up and down, to reach correct position.
Operating principle of the present utility model: at first the piston of hydraulic lifting oil cylinder stretches out, driving running block by the connector that promotes guiding device moves down, have directive wheel owing to promote on the guiding device, make the guide rail that it can stability and safety move down along pipe B.Running block was walked around the fixed pulley group by steel wire (do not have among the figure demonstration) and was connected with the pedestal earrings of mobile buffer this moment, therefore, when the piston of hydraulic lifting oil cylinder stretched out, the base rail of mobile buffer moved up along the gathering sill of pipe B.Since adopted running block (present embodiment is thought two movable pulley), one meter of the piston elongation of hydraulic lifting oil cylinder, and mobile buffer can rise four meters, but the thrust of hydraulic lifting oil cylinder is four times of its load-carrying.Can take all factors into consideration factors such as the flexible stroke of hydraulic lifting oil cylinder and load-carrying in actual design, choose reasonable pulley number reaches not only economy but also reasonably design.
After the hydraulic lifting oil cylinder gets piston and all stretches out; manipulator is put into first drilling rod in first rat hole by making up a joint; spring in the mobile buffer plays cushioning effect at this moment; impact when preventing to put down drilling rod is excessive; and the rubber pad in the conical head can be protected tool joint, and simultaneously, conical head can play the effect of certain centering; owing to also have the centring device (not shown) on the rig floor face, thereby can guarantee that drilling rod is placed on the mobile buffer more stably.The piston-retraction of hydraulic lifting oil cylinder drives running block and moves up then, and this moment, mobile buffer moved down, and when arriving proper height, the piston of hydraulic lifting oil cylinder stops retraction.The same manner is put into second drilling rod in second rat hole, and moves to proper height.Order this moment is put into first rat hole to the 3rd drilling rod with the manipulator (not shown), connects to form two thribbles by iron driller (not shown) and first drilling rod.The manipulator that makes up a joint then proposes two thribbles from first rat hole, be put in second rat hole, connects into three thribbles with iron driller (not shown) and second drilling rod.With picking thribble manipulator (not shown) three thribbles in second rat hole are put into the comb district more at last.So far finished the whole thribble operation that connects, because drilling rod is connected into two thribbles and moves to second rat hole in first rat hole after, first rat hole is idle, and the manipulator that makes up a joint this moment can continue to put into drilling rod in first rat hole, so just improved operating efficiency greatly.
Unload the operation of thribble and connect the thribble operation basic identical, at first the hydraulic lifting oil cylinder piston stretches out, driving mobile buffer moves up, after treating that piston all stretches out, by picking the thribble manipulator three thribbles are put into first rat hole, hydraulic lifting oil cylinder piston retraction drives mobile buffer and moves down then, after arriving proper height, piston stops retraction.With iron driller three thribbles are unloaded and to be single and two thribbles, with picking the thribble manipulator two thribbles are put in second rat hole, order simultaneously with manipulator single from first rat hole proposition be put into the cat road, again with iron driller the two thribbles in second rat hole unload be two single, the single usefulness on the top manipulator that makes up a joint is put in first rat hole, at last with the manipulator that makes up a joint respectively two single Mao Dao of putting into, promptly finish and unload thribble operation.Regulate the height of drilling rod apart from the rig floor face by the piston collapsing length of control hydraulic lifting oil cylinder in operating process, proper height is convenient to iron driller and the Robot actions that makes up a joint to reach.When not using, the piston-retraction of hydraulic lifting oil cylinder prevents that piston is contaminated.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
