Abstract

Apparatus for cleaning the inside of a pipeline e.g. a gas main, comprises a cleaning head 1 for insertion into and movement along the bore of a pipeline. The head 1 comprises a body 2 with, at the front end of the body 2, motor driven metallic flails 3 and brushes 4 for scouring the internal wall of the main. The body 2 has a duct 11 and a bore portion 7 through which debris is removed by means of a suction hose 13 connected to the rear of the body 2. <IMAGE>

Description

SPECIFICATION Apparatus for cleaning the inside of a pipeline The present invention relates to apparatus for cleaning the inside of a pipeline and is particularly concerned with apparatus designed to clean gas mains which contain any detritus in the form of loose debris eg dust and grit in the main of in the form of corrosion of other deposits adhering to the internal wall of the main.
According to the present invention we provide apparatus for cleaning the inside of a pipeline, the apparatus comprising a cleaning head for insertion into and movement along the bore of the pipeline, the head being adapted for dislodging from the internal wall of the pipeline any detritus adhering to the internal wall of the pipeline and for the conveyance of such and any other detritus to a hose which has one end connected to the head for movement with the head along the pipeline and its other end connected to suction means located externally of the pipeline for withdrawal of the detritus from the pipeline by way of the head and the hose.
An embodiment of the invention will now be particularly described with reference to the accompanying drawings in which: Figure 1 shows a side view in section of the cleaning head and associated suction hose and Figure 2 shows a schematic view of the apparatus in use in cleaning a gas main.
Referring to the drawings, the cleaning head 1 comprises a generally cylindrical body 2 for insertion into the movement along the bore of a gas main, there being mounted at the front end of the body 2, metallicflails3 and wire brushes4for engaging the internal wall of a gas main to sweep the wall circumferentially to remove any detritus e.g. corrosion and other deposits from the wall of the main.
The body 2 is formed with a bore 5 which has a portion 6 tapering conically from the front end of the body to the rear end where it terminates in a cylindrical portion 7.
A hydraulic motor 8 for rotating a shaft 9 upon which the flails 3 and brushes 4 are mounted is housed within a frusto-conical housing 10 which is partly received within the conical portion of the bore 5.
The housing 10 forms with the conical portion of the bore 5 a duct 11 serving as an inlet to receive detritus within the gas main.
Secured to the rear end of the body is a flanged connector 12 serving as a means for coupling a flexible vacuum hose 13 to the rear end of the head.
The cylindrical portion 7 of the bore 5 serves as an outlet to discharge the detritus to the hose 13.
Secured to the motor8 and extending rearwardly through the bore 5 and the hose 13 is a further flexible hose 14 containing fluid feed and return lines (not shown) for driving the motor 8.
Both the vacuum hose 13 and the hose 14 extend (in use) rearwardly through the gas main and terminate respectively at a suction device and a fluid pump and reservoir.
The motor housing 10 itself is secured to four skid supports 15 which are secured to the outer surface of the body in a circumferentially spaced arrangement. Mounted on each skid support 15 are pairs of spaced brushes 16 extending radially outwards and serving in use to contralise the head within the main when in use.
The brushes 4 are mounted on a bush 17 which is secured to the shaft 9, there being four such brushes 4 circumferentially spaced around the bush 17 and radially projecting therefrom.
The flails 3 are linked by chains 18 to a support frame 19 which is also mounted on the shaft 9, there being two such flails 3 arranged opposite each other on the shaft 9. In use the flails 3 are thrown radially outwardly by centrifugal force to engage the wall of main.
Referring to Figure 2, in use the vacuum hose 13 is connected to a suction device 20 by way of a cyclone 21 and filter 22, all these components being located externally of the gas main 23 whereby to remove the detritus from the main 23. The hydraulic feed and return lines are also connected to a pump (not shown) externally of the main 23.
In use the cleaning head 1 is inserted into one end of a gas main 23 having been connected to the vacuum hose 13 and the hydraulic feed and return lines. The hydraulic pump is then operated to drive the motor at high speed (e.g 900 rpm) whereby to rotate the flails 3 and brushes 4. At the same time the suction device is operated to suck air through the vacuum hose 13. The head is pushed through the main 23 and the hose 13 which is stored on a trailer mounted drum (not shown) is reeled out as the head is pushed along the bore of the main 23.
The rotating flails and brushes remove all loose debris, scale and rust from the internal wall of the gas main (assuming the main is of cast iron).
As will be seen from Figure 1 the ends of the brushes 4 are angled with respect to the axis of the main 23 to facilitate movement of the debris towards the head inlets. The main is scoured down to the bare metal or firmly adhering corrosion products.
The cleaning apparatus will remove all loose debris and deposits on the internal wall of the main including loose dust on the bottom of the main.
The device is intended as a means for cleaning out a main prior to the internal sealing of joints and fissures.
1. Apparatus for cleaning the inside of a pipeline, the apparatus comprising a cleaning head for insertion into and movement along the bore of the pipeline, the head being adapted for dislodging from the internal wall of the pipeline any detritus adhering to the internal wall of the pipeline and for the conveyance of such and any other detritus to a hose which has one end connected to the head for movement with the head along the pipeline and its other end connected to suction means located externally of the pipeline of withdrawal of the detritus from the pipeline by way of the head and the hose.
