Abstract
The utility model belongs to oil drilling equipment, and relates to an adjustable blocking alarm mechanism for a rope core drill, which comprises an elastic clamp frame lower joint positioned in a drill rod. A shaft capable of moving up and down is connected to the lower end of the elastic clamp frame lower joint, the head of the shaft is placed inside an inner hole of the elastic clamp frame lower joint and limited by a step at the lower end of the inner hole, the lower end of the shaft extends out of the elastic clamp frame lower joint, a water hole positioned on a pipe wall of the elastic clamp frame lower joint can be blocked or partially blocked when the head of the shaft ascends, an adjusting mechanism is disposed at the lower end of the shaft, the axial position of the adjusting mechanism is adjustable, and a compression spring is pressed between the upper end of the adjusting mechanism and the lower end surface of the elastic clamp frame lower joint. The adjustable blocking alarm mechanism for the rope core drill has the advantages that 1, the adjustable blocking alarm mechanism is simple and compact in structure, and the length of the drill is shortened, 2, the pressure and the stroke of blocking alarm are adjustable so that sufficient pumping pressure signals are assuredly outputted upwards, and 3, stress conditions of the shaft are changed, and the service life of the shaft is prolonged.
Description
Technical field
The utility model belongs to oil drilling equipment, relates to the adjustable obstruction of a kind of cord coring drill mechanism that notifies.
Background technology
The obstruction mechanism that notifies is one of important component part in the cord coring drill structure, its effect is in the drilling tool use, full or drill bit takes place to be hampered and to cause obstruction when the drilling tool basket, can use the operator of drilling tool to change the mode of occupation that reflects drilling tool by instrument board the pressure of the drill by the mechanical action prompting of part in the mechanism.Traditional obstruction mechanism that notifies is when rock core is filled or stop up, basket moves up, and arrive to stop up the butterfly spring of the mechanism that notifies by the transmission between part, makes the mouth of a river of shutoff joint behind its compression back generating unit displacement component cause the significant change of face of land pump pressure, prompting operation person stops boring, and fishes for rock core.But in actual use stressed of traditional cord coring drill finally concentrates on the screw thread of last adjusting nut of axle and axle, and the displacement stroke of butterfly spring is very little, the adjustable range of governor motion is also less, thereby it is not obvious to mouth of a river shutoff, the pump pressure on the face of land changes also not obvious, fails to realize fully playing the effect of notifying of stopping up.Can only raise by the pump pressure of trace and remind the user, if being arranged in the operating process slightly, carelessness may will miss this information, can only wait until that the drilling tool moment of torsion continues to raise, drilling depth could find that rock core filled basket or rock core blocking after not obvious in the work progress, can bring unnecessary harm and excessive wear to whole drilling tool like this.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of full or drill bit of basket that in the cord coring drill use, takes place to be hampered and to cause when blocking, can send significant feedback signal, and can be according to the adjustable obstruction of the cord coring drill that actual service conditions is regulated the easily mechanism that notifies.
The adjustable obstruction of the cord coring drill of the present utility model mechanism that notifies includes the bullet card frame lower contact that is positioned at drilling rod, bullet card frame lower contact lower end is connected with can upper and lower mobile axle, the head of axle is placed in the endoporus of bullet card frame lower contact and is spacing by the step of endoporus lower end, the lower contact of bullet card frame is stretched out in the lower end of axle, and the head of axle can stop up when rising or part is stopped up the limbers that is positioned on the bullet card frame lower contact tube wall; The lower end of described axle is provided with the adjustable governor motion of axial location, is pressed with a compression spring between the lower surface of the upper end of governor motion and the lower contact of card frame.
Described governor motion comprises a setscrew nut that is threaded with the hypomere of axle, the setscrew nut external surface is provided with external screw thread, be connected with locking nut and adjusting screw nut on its external screw thread from the bottom to top successively, the upper end of adjusting screw nut contacts with described compression spring by a spring top board.
The lower end of described axle is provided with flat key.
The utility model has the advantages that:
1. simple in structure, compact, shortened drilling tool length;
2. by regulating adjusting screw nut, the decrement that changes spring can be regulated and be stopped up the required jacking force of reporting to the police, and to stop up notify pressure and stroke adjustable thereby make, to guarantee upwards to export enough pump pressure signals.
3. by setscrew nut and flat key structure, change the stressing conditions of axle, the active force of below can have been acted on respectively on adjusting nut and the setscrew nut, prolonged its application life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, the adjustable obstruction of this cord coring drill mechanism that notifies includes the bullet card frame lower contact 1 that is positioned at drilling rod, bullet card frame lower contact lower end is connected with can be upper and lower mobile axle 2, axle 2 head is placed in the endoporus of bullet card frame lower contact and is spacing by the step of endoporus lower end, bullet card frame lower contact 1 is stretched out in the lower end of axle, and the head of axle can stop up when rising or part is stopped up the limbers that is positioned on the bullet card frame lower contact tube wall; The lower end of axle is provided with the adjustable governor motion of axial location, is pressed with a compression spring 3 between the lower surface of the upper end of governor motion and the lower contact of card frame.
Described governor motion comprises a setscrew nut 7 that is threaded with the hypomere of axle 2, the setscrew nut external surface is provided with external screw thread, be connected with locking nut 6 and adjusting screw nut 5 on its external screw thread from the bottom to top successively, the upper end of adjusting screw nut contacts with compression spring 3 by a spring top board 4.The lower end of axle is provided with flat key 8.
