Abstract
The utility model discloses a drilling tool adapter, which comprises a joint, a small core pipe and a core pipe, wherein one end of the small core pipe is positioned in one end of the core pipe, and an inner rubber spring and an outer rubber spring are sleeved at the other end of the small core pipe; both the small core pipe and the core pipe are arranged in the joint; a clamping key is arranged between the joint and the core pipe, and a rear gland is arranged at the top of the joint; the rear gland is fixed on the joint through a fastener; and a spring is sleeved at one end of the core pipe on the outer part of the joint. When the drilling tool adapter is screwed with a drilling tool, the drilling tool adapter with power applies a great impact force onto the drilling tool, and the impact on the drilling tool can be effectively reduced through a rubber spring assembly, so that threads on the drilling tool and the joint are protected; and when the drilling tool adapter is loosened and separated from the drilling tool, the drilling tool adapter can retreat while loosening by means of the acting force of the spring, so that the threads are protected and the drilling tool adapter does not block the drilling tool in situ. The drilling tool adapter effectively achieves the effects of protecting the drilling tool in idle travel and avoiding damaging the drilling tool during screw-off.
Description
Technical field
The utility model belongs to engineering machinery (rig) technical field, particularly a kind of drilling tool adapter.
Background technology
The working environment of rig is comparatively complicated and abominable, and its part and structure are design principles with simple, practicality all; Require to install and convenient disassembly, and for ease of maintenaince, be fit to open-air area and use.All there are complex structure, installation and the inconvenient limitation of maintenance in the structural drilling tool adapter of conventional machinery mechanism; In addition; The process that drilling tool adapter commonly used and drilling tool are screwed mutually and screwed out can have bigger impact force and vibrations to drilling tool, easy damaged screw structure.
The utility model content
In order to solve impact force, big, the baroque problem of vibrations that the drilling tool adapter exists in the above-mentioned prior art, the purpose of the utility model is to provide a kind of drilling tool adapter, can solve this problem exactly.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of drilling tool adapter comprises joint; Said adapter also comprises little core pipe and core pipe; One end of said little core pipe is positioned at the end inside of said core pipe, rubber spring and outer rubber spring in the other end of said little core pipe is arranged with, and said little core pipe is arranged in the said joint together with said core Guan Jun; Be provided with the card key between said joint and the said core pipe; And the top of said joint is provided with rear pressing cover, and rear pressing cover is fixed on the said joint through securing member, and said core pipe is positioned at the outside end of said joint and is arranged with spring.
Preferably, said little core pipe is provided with sealing ring with the position that said core pipe is connected.
Preferably, the lower end of said joint is provided with two backing pins.
Preferably, the said core pipe position that is provided with spring is provided with fairlead.
Preferably, be provided with locking plate between said rear pressing cover and the securing member, be provided with locking plate between said joint and the securing member.
The drilling tool adapter mainly is to screw mutually with the internal thread on the drilling tool through the external screw thread on the joint, the purpose of holing transmission of power to drilling tool.
The beneficial effect of the utility model: the drilling tool adapter in the utility model is and the supporting use of drilling tool; The process of screwing mutually when drilling tool adapter and drilling tool; The drilling tool adapter that has power to the end can have bigger impact force to drilling tool; Can effectively reduce impact through the rubber spring assembly, with the screw thread of protection drilling tool part and blank area to drilling tool; When drilling tool adapter and drilling tool unscrew in the process that withdraws from mutually, rely on the active force of spring, the drilling tool adapter can shrink back, and can accomplish to move back while unscrewing, and with the protection screw thread, guarantees that the drilling tool adapter do not eat tooth in the original place to drilling tool.When effectively reaching idle stroke protection drilling tool, shackle, the drilling tool adapter do not hinder drilling tool.
Description of drawings
Fig. 1 is the structural representation of drilling tool adapter in the utility model;
Among the figure: 1 rear pressing cover, 2 card keys, 3 outer rubber springs, 4 interior rubber springs, 5 backing pins, 6 joints, 7 little core pipes, 8 O type circles, 9 bolts, 10 locking plates, 11 nuts, 12 core pipes, 13 springs, 14 fairleads.
The specific embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
A kind of drilling tool adapter; Comprise joint 6, said adapter also comprises little core pipe 7 and core pipe 12, and an end of said little core pipe 7 is positioned at the end inside of said core pipe 12; Rubber spring 4 and outer rubber spring 3 in the other end of said little core pipe 7 is arranged with; Said little core pipe 7 all is arranged in the said joint 6 together with said core pipe 12, be provided with card key 2 between said joint 6 and the said core pipe 12, and the top of said joint 6 is provided with rear pressing cover 1; Rear pressing cover 1 is fixed on the said joint 6 through securing member, and said core pipe 12 is positioned at said joint 6 outside ends and is arranged with spring 13.
