Abstract
The utility model discloses a kind of submersible drilling tool.It is that the sealing shroud that is rotatably assorted and can be moved axially along drilling rod is set on drilling rod, and the realization of end thread fixed operating sleeve.Due to the setting of sealing shroud, the connecting tube being welded on circulating water pipeline can be connected through valve with sealing shroud by sealing shroud, utilize the sealing and guide effect of sealing shroud, under rotary power effect, drilling rod drives drill bit, and the position drilling corresponding to the connection inside pipe wall on circulating water pipeline is smoothly welded on the corresponding tube wall for have recirculated water, recirculated water is reached valve by connecting tube, close valve directly can just be connected with other parts, be reliably completed the task of low-temperature treatment.Except solve the goal of the invention of submersible and in addition to, also have the advantages that unique inventive concept, simple and compact for structure, sealing high safety, small in volume, operation flexible durable, reduce labor intensity, improves operating efficiency, not only economic but also practical, social benefit significantly, be adapted to industry popularization.
Description
Technical field
A kind of drilling tool is the utility model is related to, is supplied more particularly to during a kind of heating in the winter time in order to not influence system
In the case of warm, the drilling tool that is used when being mounted directly connecting tube and the i.e. submersible of heating equipment on circulating water pipeline.
Background technology
Heating system those skilled in the art are it is well known that a job of winter workload maximum is exactly to carry out low temperature to user
Processing.Described is that the user relatively low to room temperature installs portion additional again on the basis of original heating equipment to user's progress low-temperature treatment
Divide heating equipment, to improve room temperature.Due to the limitation of current drilling tool structure, cause to stop when carrying out low-temperature treatment for user
Only heat supply in region, while could implement drilling operation after the water in pipeline is all bled off.Stop in system or subregion
Carried out in the case of fortune（Alternatively referred to as anhydrous operation）.So, many troubles are not only increased, and can be to being used in region
Family life, which is brought, to be directly affected.Therefore, do not have to discharge water again if a kind of heat supply neither in influence area can be studied, so that it may enter pipeline
Row bore operation simultaneously installs the submersible drilling tool that heating equipment uses and just seems particularly significant.
The content of the invention
The purpose of this utility model is to provide a kind of submersible drilling tool, and band can not be carried out by mainly solving existing drilling tool
Water operation, can not realize to user carry out low-temperature treatment when heating equipment install the problem of.
The utility model includes drill bit, drilling rod and adapter sleeve, and the drilling rod is extension rod, sets and rotates on the drilling rod
The sealing shroud that can be moved axially with merging along drilling rod, and through end thread fixed operating sleeve.
The transition section of the drilling rod and drill bit is provided with Ring-cylindrical ladder boss.
Described sealing shroud is that an inside is provided with the shoulder hole phase corresponding with the ladder boss of drilling rod, drill bit transition section
The axially extending bore of insertion, the bicyclic groove of built-in sealing ring is provided with the through-hole wall by drilling rod end side, and by drill bit side
Outside port be threaded the connecting elements of composition.
The beneficial effects of the utility model：Due to taking the setting of the structure, particularly sealing shroud, it can be by close
The connecting tube being welded on circulating water pipeline is connected by big envelope through valve passage with sealing shroud, using the sealing of sealing shroud with leading
To effect, under rotary power effect, drilling rod drives drill bit, and circulation is successfully welded on the corresponding tube wall for have recirculated water
The position drilling corresponding to connection inside pipe wall on waterpipe, makes recirculated water reach valve by connecting tube, closes valve with regard to energy
Directly it is connected with other parts, is reliably completed the task of low-temperature treatment.Except solve submersible reliably realize goal of the invention and
Outside, also with inventive concept it is unique, it is simple and compact for structure, sealing high safety, small in volume, operation flexible durable, subtract
Light work intensity, not only raising operating efficiency, economy but also practicality, social benefit is notable, is adapted to the advantages that industry popularization.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram；
Fig. 2 is Fig. 1 A-A sectional views.
Embodiment
The submersible drilling tool of the present utility model as shown in Fig. 1, Fig. 2, it is that the one kind invented in existing heat supply practice is new
Type drilling tool.Its one end is drill bit 1, and the rear portion of drill bit 1 is drilling rod 2, and drilling rod 2 is extension rod, in the transition of drill bit 1 and drilling rod 2
Section is Ring-cylindrical ladder boss 3.A sealing shroud 4 being enclosed on outside it is provided with drilling rod 2, the sealing shroud 4 is in individual
Portion is provided with the axially extending bore that the shoulder hole corresponding with the ladder boss 3 of drilling rod, drill bit transition section connects, by drilling rod 2
The through-hole wall of end side is provided with the bicyclic groove of built-in sealing ring 5, and is threaded group on the outside port by the side of drill bit 1
Into connecting elements.The sealing shroud 4 is rotatably assorted with drilling rod 2, and can be axially i.e. movable along drilling rod 2.At the end of drilling rod 2
Portion is through the adapter sleeve 6 that is screwed.
During work, whole drilling tool is fixedly connected with motor drive mechanism by adapter sleeve 6, flexibly bored to rotate drilling rod 2
Lubricating oil is scribbled between bar 2 and sealing shroud 4.When implementing low-temperature treatment using the utility model, valvular company will have first been connected
Pipe ends are welded on the thermal cycling pipe of interior water flowing, slide sealing shroud 4 of the present utility model, and drilling rod 2 is relative with drill bit 1
Motion causes drill bit 1 to be placed in sealing shroud 4 backward, now drilling rod 2, the transition section of drill bit 1 ladder boss 3 just and sealing shroud
The ladder seam fitting of corresponding shoulder hole in 4.Screw thread of the sealing shroud 4 through being set on outside port is connected admittedly with valve
It is fixed.Valve is opened, is then exerted oneself forward, promotes that drilling rod 2, drill bit 1 are pushed ahead and the front portion of drill bit 1 withstands on circulating line lateral wall
On, motor drive mechanism controlling switch is opened, motor drive mechanism drives drilling rod 2, drill bit 1 in the internal rotation of sealing shroud 4, due to sealing shroud 4
The band water bore operation of drilling tool is smoothly realized in guide-localization effect.Under double seal ring 5 acts in sealing shroud 4 simultaneously, operated
Cheng Zhongshui can not flow out at all.Valve is closed after fulfiling assignment, then screws off sealing shroud 4, makes sealing shroud 4 together with entirety and pipeline
The component of connection departs from.The utility model thoroughly changes traditional anhydrous operating type, eliminates low temperature family for heat supply and creates well
Condition.
