Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 6 together, a defect cleaning device for a cast iron pipe lining according to the present invention will now be described. The cast iron pipe lining defect cleaning device comprises a supporting driving assembly 7, an inserted link 1, a supporting sleeve 2, a sliding sleeve 3 and a sleeve body driving assembly 4.

The support driving assembly 7 is used for being installed on the ground, supporting the tubular body 100 and driving the tubular body 100 to rotate in the circumferential direction thereof.

One end of the insert rod 1 is used for being inserted into the pipe body 100, and the insertion end is provided with a striking component 6 for striking the lining, specifically, the striking component 6 comprises a striking part for striking the lining; when the support driving component 7 drives the pipe body 100 to rotate along the circumferential direction, the impact part moves back and forth along a certain distance and frequency and moves the impact part along the axial direction of the pipe body 100, so that the impact part impacts the inner lining, the inner lining is impacted to have the same thickness, and the technical effect of eliminating the defects of the inner lining is achieved. The other end of the inserted link 1 is positioned outside the pipe body 100 and is connected with a link body driving component 5; specifically, the rod driving assembly 5 is used for being installed on the ground, and the power driving end can move along the axial direction of the inserted rod 1, so as to drive the inserted rod 1 and the striking assembly 6 to move along the axial direction of the pipe body 100. The insert rod 1 is further provided with a stopper 11 extending in the radial direction of the insert rod 1.

For convenience of description, in the present embodiment, the axial direction of the plunger 1 is defined as the front-rear direction, and the direction in which the plunger 1 is inserted into the pipe body 100 is defined as the front.

The support sleeve 2 is slidably sleeved on the insertion rod 1 along the front-back direction. The front end of the support sleeve 2 is provided with an abutment plate 21 for abutting against the stopper 11.

The sliding sleeve 3 is slidably sleeved on the supporting sleeve 2 along the front-back direction. A plurality of swinging pieces 31 are arranged on the peripheral wall of the sliding sleeve 3; specifically, the plurality of rocking members 31 are equiangularly distributed along the circumferential direction of the outer peripheral wall of the sliding sleeve 3 such that the end of each rocking member 31 is located on a circle (for convenience of description, this circle is named as "abutment circle" in the present embodiment); and the other end of each swinging member 31 is hinged to the outer peripheral wall of the sliding sleeve 3. The swinging members 31 are respectively abutted against the outer edges of the abutting plates 21, and when the sliding sleeve 3 slides in the axial direction thereof, the swinging members 31 swing around a hinge point (the "hinge point" referred to herein is a hinge position of the swinging members 31 and the sliding sleeve 3), and the area of the abutting circle increases or decreases in the process, so that the ends of the swinging members 31 can abut against the inner wall of the socket 200 or the inner wall of the pipe body 100.

The sleeve body driving assembly 4 is connected with the support sleeve 2 or the sliding sleeve 3, and is used for driving the insertion rod 1, the support sleeve 2 and the sliding sleeve 3 to move in the up-down direction and driving the sliding sleeve 3 to slide in the front-back direction.

The following operations can be realized through the sleeve body driving component 4 and the rod body driving component 5:

A. the rod body driving component 5 drives the inserted rod 1 to move backwards until the limiting component 11 abuts against the abutting plate 21, at the moment, the sleeve body driving component 4 drives the sliding sleeve 3 to move along the front-back direction, and the swinging component 31 is hinged with the sliding sleeve 3 and abuts against the outer edge of the abutting plate 21, so that the end part of the swinging component 31 can be opened or closed along the radial direction of the sliding sleeve 3, and the area of the abutting circle is increased or reduced;

B. when the limiting member 11 abuts against the abutting plate 21, the rod body driving assembly 5 and the sleeve body driving assembly 4 respectively drive the insertion rod 1 and the sliding sleeve 3 to move along the same direction and the same power, so that the insertion rod 1, the support sleeve 2 and the sliding sleeve 3 all move along the direction, and the horizontal position of the swinging member 31 is changed.

In the lining defect cleaning stage, firstly, the central axis of the pipe body 100 needs to be found, and the insert rod 1 is located on the central axis of the pipe body 100, and the specific steps are as follows:

the field worker increases the area of the abutment circle to be close to the inner diameter of the socket 200 through the operation a; then the sleeve body driving component 4 drives the supporting sleeve 2 and the sliding sleeve 3 to move up and down, so that the center of the abutting circle is close to the central axis of the pipe body 100; finally, the inserted rod 1, the support sleeve 2 and the sliding sleeve 3 are moved forward through the operation B, the area of the abutting circle is adjusted through the operation A, the vertical position of the abutting circle is adjusted through the sleeve body driving assembly 4, and finally the swinging piece 31 is inserted into the socket 200, the end of the swinging piece 31 abuts against the socket 200, and the inserted rod 1 is coaxial with the pipe body 100.

Then, the field worker drives the pipe body 100 to rotate through the supporting driving assembly 7, and drives the inserted rod 1 to axially move along the pipe body 100 through the rod body driving assembly 5; and starting the striking assembly 6 to enable the striking part of the striking assembly 6 to strike the lining at different parts in the pipe body 100, so as to clean the lining defect of the pipe body 100.

Finally, the area of the abutting circle is reduced by the operation a, and the oscillating piece 31 is inserted into the pipe body 100 to move back and forth by the operation B, and since the end of the oscillating piece 31 at this time abuts against the inner wall of the pipe body 100 (it can be understood that the end abuts against the inner liner of the pipe body 100), if the sliding sleeve 3 rotates about the support sleeve 2, the defect of the protrusion still exists on the inner liner of the pipe body 100, and the defect removal of the inner liner needs to be performed again.

Compared with the prior art, the cast iron pipe lining defect cleaning device provided by the invention can be used for removing and cleaning the lining, so that the manual working process is avoided, and the working efficiency is improved. By abutting the swinging piece 31 against the lining of the pipe body 100, when the pipe body 100 rotates, whether the lining at the position has defects can be judged by observing whether the sliding sleeve 3 rotates, so that the effect of detecting the defects of the lining is achieved, and the product quality is ensured.

It should be added that, for the cast iron pipe to be subjected to lining defect elimination, the field worker generally measures and compares the diameter of the abutting circle with the known inner diameter of the preset cast iron pipe, so as to optimize the fine adjustment process and eliminate or reduce the time required by the process; in order to make the area of the abutting circle easier to measure, the number of the swinging pieces 31 is generally even, and a field worker can obtain the diameter of the abutting circle by detecting the distance between the end parts of the two swinging pieces 31 which are symmetrical to each other by taking the center of the abutting circle as the center, so that the area of the abutting circle can be calculated very easily.

After the torsion spring 32 is damaged, when the sliding sleeve 3 is driven to move forwards by the sleeve body driving component 4, the situation that the swinging piece 31 cannot be inserted into the cast iron pipe due to too much radial deviation along the abutting plate 21 can be avoided; by adopting the technical scheme, after one torsion spring 32 is damaged, the device can still be used continuously, and the stability of the device in actual use is enhanced.

It should be noted that a pressure sensor may be provided on the side of the retainer ring 211 facing the corresponding swing piece 31, so that whether or not the swing piece 31 abuts against the retainer ring 211 can be determined from the value of the pressure sensor (when the torsion spring 32 is not damaged, the swing piece 31 abuts against the abutment plate 21 and does not abut against the retainer ring 211, and when the value is displayed on the pressure sensor on the retainer ring 211, it is determined that the retainer ring 211 receives the pressure from the swing piece 31, and therefore, the torsion spring 32 can be damaged here).

Referring to fig. 4, as a specific embodiment of the device for cleaning the lining defect of the iron pipe provided by the present invention, an anti-separation element 311 for abutting against the abutting plate 21 and/or the limiting ring 211 is disposed on a portion of the oscillating element 31 that passes through the limiting ring 211, specifically, the anti-separation element 311 is fixed on a side of the oscillating element 31 for abutting against the iron pipe, and the abutting plate 21 and/or the limiting ring 211 are abutted by the anti-separation element 311, so that the abutting plate 21 and the oscillating element 31 can be prevented from separating.
