Abstract
The utility model discloses an automatic constant diameter undergauge machine of bushing pipe in HDPE, including the frame, the interval is provided with multilayer work panel in the frame, sets up the undergauge unit on the work panel respectively: four gyro wheels that the undergauge unit set up including the symmetry, its outer working face link to each other and have enclosed into crossing the pipe passageway, be provided with the backup pad on the work panel in the gyro wheel outside, the working shaft of gyro wheel passes through the bearing supporting rack and links to each other with the backup pad, be arranged in into, go out two undergauge units of pipe end, the working shaft of a gyro wheel outwards extends, and the driving bevel gear that sets up it on and hydraulic motor export epaxial bevel gear and mesh mutually, the transition bevel gear that all the other two adjacent gyro wheels pass through the working shaft both ends meshes mutually. The utility model has the advantage of simple structure, compactness, undergauge machine advance the pipe with the undergauge unit that goes out the pipe end on the undergauge gyro wheel adopt hydraulic motor to drive to rotate, with its operation line speed regulation be with the tractor in step, reduced the pulling force of tractor, the length that has lengthened the single poling.
Description
Technical field
The utility model relates to pipe rehabilitation technology, especially relates to a kind of HDPE internal lining pipe automatic equal-diameter size reducing machine.
Background technology
When repairing water supply and sewerage pipeline, gas collector and delivery pipe, oil field gathering and transportation pipeline etc., usually need to adopt non-excavation repairing technique.No-dig technique liner repairing used pipeline technology applies existing more than 20 years at home, it utilizes HDPE(high density polyethylene (HDPE)) material has the feature of shape memory, before HDPE bushing pipe inserts pipeline to be repaired, the diameter of HDPE bushing pipe is temporarily reduced, then be drawn in old pipeline to be repaired, utilize heating or pressure method that the diameter of this bushing pipe is returned to original diameter, form tube-in-tube, to reach the object of repairing old pipe.The Distance geometry that this method both can improve poling reduces joint quantity, can reduce again wearing and tearing when HDPE bushing pipe is migrated in old pipeline.Unpowered for the roller type size reducing machine self of contracting HDPE liner diameter at present, during work, hauling machine will treat that the HDPE bushing pipe of undergauge passes from size reducing machine roller, and between roller and bushing pipe, resistance is very large, cause hauling machine pulling force excessive, constrain the length of single poling.
Summary of the invention
The purpose of this utility model is to provide a kind of HDPE internal lining pipe automatic equal-diameter size reducing machine, reduces the pulling force of hauling machine during work, improves the length of single poling.
For achieving the above object, the utility model can take following technical proposals:
HDPE internal lining pipe automatic equal-diameter size reducing machine described in the utility model, comprise the frame being rectangle frame structure, described frame is arranged at intervals with multiple benches panel, described working panel was respectively arranged with tube passage diameter to successively decrease successively and the identical undergauge unit of structure, described undergauge unit comprises the arc roller of symmetrically arranged four sub-kidney-shaped structures, and the outer working face of described four arc rollers is connected and defined tube passage; Working panel outside described arc roller is respectively arranged with gripper shoe, and the working shaft of described arc roller is connected with described gripper shoe mutually by the bearing bearing support at two ends; Be arranged in inlet pipe end and going out pipe end two undergauge unit, the working shaft of one of them arc roller stretches out, be provided with driving bevel gear, described working panel is provided with hydraulic motor, the bevel gear be arranged on described hydraulic motor output shaft is meshed with described driving bevel gear; All the other adjacent two arc rollers are meshed by the transition bevel gear at its working shaft two ends.
Described frame is arranged at intervals with four layers of working panel, the tube passage diameter crossed being arranged on the undergauge unit on four layers of working panel successively decreases 5mm successively.
The utility model has the advantage of that structure is simple, compact, size reducing machine inlet pipe and the undergauge roller gone out on the undergauge unit of pipe end adopt hydraulic motor (hydraulic motor supplies power by external hydraulic pump station) to drive and rotate, its travel line speed is adjusted to synchronous with hauling machine, greatly eliminate the resistance between arc roller and HDPE internal lining pipe when size reducing machine works, reduce the pulling force of hauling machine, extend the length of single poling.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left TV structure schematic diagram of Fig. 1.
Detailed description of the invention
As shown in Figure 1, 2, HDPE internal lining pipe automatic equal-diameter size reducing machine described in the utility model, comprise the frame 1 being rectangle frame structure, frame 1 is arranged at intervals with four layers of working panel 2, be respectively arranged with tube passage 3 diameter to successively decrease successively 5mm and the identical undergauge unit of structure from inlet pipe end to the working panel 2 going out pipe end: the outer working face that this undergauge unit comprises arc roller 4, four arc rollers 4 of symmetrically arranged four sub-kidney-shaped structures is connected and defined tube passage 3; Working panel 2 outside arc roller is respectively arranged with gripper shoe 5, and the working shaft of arc roller 4 is connected with gripper shoe 5 mutually by the bearing bearing support 6 at two ends; Be arranged in inlet pipe end and going out pipe end two undergauge unit, the working shaft of one of them (be shown as in Fig. 1 and be arranged on working panel top) arc roller 4 stretches out, be provided with driving bevel gear 7, working panel 2 is provided with hydraulic motor 8, and the bevel gear 9 be arranged on hydraulic motor output shaft is meshed with driving bevel gear 7; All the other adjacent two arc rollers are meshed by the transition bevel gear 10 at its working shaft two ends.
During utility model works, treat that the HDPE internal lining pipe of undergauge enters from the left end of size reducing machine under the pulling of hauling machine, the arc roller 4 of first order undergauge unit is under the drive of hydraulic motor 8, with hauling machine synchronous axial system, by reduced 5mm, then through the second level, after third level undergauge unit reduces diameter again, enter fourth stage undergauge unit, the arc roller 4 of fourth stage undergauge unit is under the drive of hydraulic motor 8, same and hauling machine synchronous axial system, again compress the diameter of HDPE internal lining pipe to design size, because the arc roller 4 of the first order and fourth stage undergauge unit drives active rotation by hydraulic motor 8, greatly eliminate the resistance between internal lining pipe and roller in liner undergauge process, compared with the unpowered size reducing machine of tradition, single undergauge internal lining pipe length can extend more than 30%, during for Old pipeline's rehabilitation, increase the length of single bushing pipe, ensure that repairing quality, improve remediation efficiency.
