Abstract

A multi-grade series connection type round tube diameter shrinkage machine driven by a liquid motor is a round tube requiring the materials with diameter shrinkage for stretch through a multi-grade rolling pressure wheel group to compress gradually and through the liquid motor as the motivation to achieve the synchronization and coordination work for all the grades of rolling pressure wheel. The utility model takes advantages of low energy consumption, speed changing without grade and automatic speed adjustment; The utility model is used at the project spots, in particular to the liner suffice construction of the plastic pipe with inner anti-corrosion at the buried pipeline and the pipeline at the bottom sea of the oil project.

Description

The plural serial stage tandem type pipe size reducing machine that fluid motor drives

The utility model relates to the plural serial stage tandem type pipe size reducing machine that a kind of novel fluid motor drives.It is the architecture advances to the carrying out of mechanical type pipe size reducing machine.It mainly is by adopting fluid motor to drive multistage roll extrusion wheels, and makes roll extrusion wheels synchronous synergetic at different levels work compress step by step, the stretch pipe of the various materials that need undergauge.It mainly is to be made of multistage roll extrusion wheels and fluid motor etc.

At present, job site in all kinds of engineerings, especially all kinds of petroleum pipelines in the oilfield engineering, all need to carry out work such as all kinds of anticorrosion, leakproofs, scale removal and reparation in putting into operation preceding or putting into operation, its workload is big, labour intensity is big, the construction period is long and need all multifactor operating efficiency of construction and benefits of enterprise of having reduced widely such as manpower is many.In recent years, the international petroleum tissue stipulates clearly that to submarine transport oil pipeline must apply anti-corrosion pipe (as polyethylene pipe) at the pipe interior lining can use.Therefore, to can the corrosion-resistant plastic tube (as polyethylene pipe) how to serve as a contrast the problem of applying in oil pipeline and become construction key in the oilfield engineering.Report according to data from abroad, though there is a kind of equipment that can carry out the undergauge stretching to polyethylene pipe in the U.S., but its complex structure, manufacturing cost height, make the user forbidding, what especially the Power Drive Unit of this equipment adopted is hydraulic control, operation easier is big, control accuracy is not high, has brought many inconvenience to site operation.Though domestic have a similar pipe undergauge device, it be the frequency control motor that adopts as Power Drive Unit and mechanical gear formula mechanism, make integral device power consumption, noise big, gear exposes many drawbacks such as also causing grease contaminated.

The purpose of this utility model provides a kind of fluid motor to drive with regard to being to avoid above-mentioned the deficiencies in the prior art part plural serial stage tandem type pipe size reducing machine, it had both overcome with the gear mechanism formula size reducing machine caused all kinds of drawbacks of motor as power, can adjust the roll extrusion wheel rim by adjustment screw easily and flexibly again and do radial displacement.It is to be made of fluid motor drive unit and multistage roll extrusion wheels, and its major technology characteristics are that multistage roll extrusion wheels are to be in series successively; And every grade of roll extrusion wheels are to be symmetrical arranged at grade by active rolling wheel (2) and three groups of driven rolling wheels (3) that three groups of fluid motors drive, its each rolling wheel is installed in respectively on the axle bed frame that can adjust distance of shaft centers, and becomes 60 degree angle settings by the order of active rolling wheel and driven rolling wheel successively.

Accompanying drawing 1 is overall structure schematic diagram of the present utility model.

Accompanying drawing 2 is the structural representation that fluid motor of the present utility model is connected with the core wheel rotating cylinder.

Accompanying drawing 3 is the fixed form schematic diagram of roll extrusion wheel rim of the present utility model and core wheel rotating cylinder.

Accompanying drawing 4 is the light boom hoisting use principle schematic diagram that disposes of the present utility model.

In order to realize better above-mentioned purpose of the present utility model, design person of the present utility model is with whenever The power of organizing the wheel core rotation tube (9) of Actively-rolled wheel (2) connects to award to hold and is designed to the moving of direct and fluid motor (8) Power output shaft is located by connecting mutually, and the wheel rim (11) of rolling wheel directly is fixed on wheel core rotation tube (9) middle part Centring ring on, and be provided with and adjust screw (12) and tighten up bolt (14).

Cooperate light boom hoisting to install and adjust for convenience and respectively organize rolling wheel, the designer also can offer special-purpose upending frame positioning and fixing jack in the centres at different levels of frame (1).

The drawing of accompanying drawing is described as follows: the front gland 11---hydraulic pressure wheel rim 12---wheel rim of positioning seat 8---fluid motor 9---core wheel rotating cylinder 10---fluid motor is radially adjusted screw 13---and is adjusted nut 14---clamping bolt 15---Special lifting device behind the driven rolling wheel 4---of the 1---main body frame 2---Actively-rolled wheel 3---roller guiding mechanism 5---hydraulic oil pipe 6---Hydraulic Station 7---fluid motor

Come enumeration design feature of the present utility model below in conjunction with drawings and Examples.

In actual design with in making, designer of the present utility model adopts multistage roll extrusion wheels to connect, every grade of roll extrusion wheels then are designed to three groups of initiatively rolling wheel and three groups of driven rolling wheels, and be symmetrical arranged at grade, its each rolling wheel is installed in respectively on the axle bed that can adjust distance of shaft centers, and becomes 60 degree angle settings by the order of active rolling wheel and driven rolling wheel successively; In order to guarantee the uniformity of speed governing, the power of every group of active rolling wheel connects to award to hold and directly is located by connecting mutually with the power output shaft of fluid motor; The roll extrusion wheel rim directly is fixed on the interfix ring of rotating cylinder, can utilizes adjustment screw to promote the roll extrusion wheel rim and do radial displacement, thereby can make six roll extrusion wheel rims of every grade form a full circle better.

Compared with prior art, the utlity model has following advantage: 1. owing to adopted fluid motor directly to drive roll extrusion wheel rim justify the managing of various materials of compressing step by step, stretch The undergauge operation, and change rotating speed by the flow of regulator solution motor oil inlet quantity, thereby realize each The synchronous coordination operation of level rolling wheel. Also can adjust into the pressure of oil mouthful oil and change turning round of fluid motor Square is realized the change of caliber compression power. 2. owing to adopted the fluid motor output shaft directly to be connected and fixed with wheel core rotation tube, not only guarantee The axiality of fluid motor and roller wheel core rotation tube, also make its structure compactness, reduced umbrella type tooth The shortcoming that power consumption is big, noise is big of taking turns outside transmitting torque and causing, and reduced because tooth Take turns the pollution problem of the lubricating grease that exposes and cause.

The utility model is reasonable in design, simple in structure, easy to operate, has that energy consumption is low, noise is little, does not have The advantages such as pollution, its machine volume is little, performance good, operate steadily. Be adapted at the underground of city road Bury construction, especially the burying in petroleum works of the anticorrosion transformation of reparation that water pipe, gas pipe do not excavate The lining of the interior anti-rot plastic pipe of ground pipeline and submarine pipeline applies the construction aspect and very uses.
