Description

Improved mop head

Technical Field

The utility model relates to a directional drilling technical field specifically is a head is dragged in improvement.

Background

The directional drill is a pipeline construction process in the engineering technology industry, generally used for the construction of petroleum, natural gas and some municipal pipelines, and is carried out after the processes of positioning drilling, reaming, cleaning holes, dragging pipelines and the like by a large-scale directional drill, and the directional drill construction method has the advantages of small required operation space, small traffic influence, rapid construction, short construction period, reduced occurrence of off-road and house cracks due to construction, minimum limit for processing barriers of existing buried objects, less required excavation space, easy safety protection and the like, so the directional drill is developed rapidly, the directional drill is an accessory applied in non-excavation construction, the existing directional drill has certain defects, the pipeline is inconvenient to pull out, the pipeline surface damage is easy to cause, the pipeline cannot be effectively protected, the structure is not reasonable enough, the production cost is high, the service life is short, and therefore an improved mop head is provided to solve the defects.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to overcome current defect, provide an improvement and drag the head, make things convenient for the pipeline to pull out, avoid causing pipeline surface damage, can carry out effectual protection to the pipeline, structural design is reasonable, low in production cost, long service life can effectively solve the problem in the background art.

In order to achieve the above object, the utility model provides a following technical scheme: an improved mop head comprises a protective barrel and a mop head body;

protecting the barrel: the left end of the protection barrel is fixedly connected with a reamer, the reamer penetrates through a through hole in the left end of the protection barrel, the right end of the reamer is fixedly connected with the left end of the transfer case through a pin shaft, and the transfer case is located inside the protection barrel;

the mop head body: the mop head body is fixedly connected to the right end of the transfer case through a pin shaft and is positioned inside the protection barrel;

wherein: still include the drill bit, drill bit fixed connection is in the left end of enlarger, will return the right-hand member round hole fixed connection who drags the pipeline and drag the head body, built-in journal bearing and the thrust bearing of transfer case, when directional brill rig drive made the enlarger rotate, it remains not changeing to return the pipeline of dragging, only receive and drag power and do not receive the moment of torsion, in order to avoid returning to drag the pipeline and produce the distortion, it is not impaired to keep returning to drag the pipeline, it is rotatory to drive the reamer, the drill bit is more thin to be easily passed from the underfloor, the protection bucket plays the guard action to divider and return and drag the pipeline, prevent underground stone, mud etc. causes the damage to divider and back to drag the pipeline, this improvement drags head structural design rationally, low in production cost, can effectively prolong the life of equipment.

Furthermore, the right end of the mop head body is provided with a round hole, so that the back-dragging pipeline can be conveniently installed.

Furthermore, still include and return the pipeline that drags, the left end that returns the pipeline that drags and drag the inside fixed connection of right-hand member round hole of head body.

Compared with the prior art, the beneficial effects of the utility model are that: the improved mop head has the following advantages:

drag the pipeline and drag the right-hand member round hole fixed connection of head body back, built-in journal bearing and thrust bearing of transfer case, directional drilling rig drives when making the enlarger rotate, it keeps not changeing to drag the pipeline back, only receive and drag power and do not receive the moment of torsion, in order to avoid dragging the pipeline back and produce the distortion, it is not impaired to keep dragging the pipeline back, the enlarger drives the drill bit rotation, the drill bit is more thin passes from the underfloor easily, the protection bucket plays the guard action to stopper and back dragging the pipeline, prevent underground stone, mud etc. causes the damage to stopper and back dragging the pipeline, this improvement drags first structural design rationally, low in production cost, can effectively prolong the life of equipment, high durability and convenient use.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1 drill bit, 2 enlargers, 3 protective barrels, 4 transfer cases, 5 dragging head bodies and 6 back dragging pipelines.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: an improved mop head comprises a protective barrel 3 and a mop head body 5;

protection barrel 3: protection barrel 3's left end fixedly connected with enlarger 2, protection barrel 3 plays the guard action to divider 4 and drag pipeline 6 back, extension transfer case 4's life, prevent to destroy the surface of pipeline, reamer 2 passes the through-hole of protection barrel left end, reamer 2's right-hand member is through the left end fixed connection of round pin axle with transfer case 4, transfer case 4 is located protection barrel 3's inside, the built-in journal bearing and the thrust bearing of transfer case 4, when making reamer 2 rotate, drag pipeline 6 back and keep not changeing, only receive and drag power and do not receive the moment of torsion, in order to avoid dragging pipeline 6 back and produce the distortion, it is not impaired to keep dragging pipeline 6 back.
