Technical Field

[0001] The utility model relates to a pipeline repair device, in particular to a telescopic lamp holder for LED curing repair. Background Art

[0002] During the non-excavation repair of pipelines, lamp holders are often required. Especially when lining and repairing drainage pipelines with a small diameter, a light curing technology is adopted. At this time, the LED lamp holder is particularly important as a key device for supporting and guiding the LED light source (usually an ultraviolet LED lamp).

[0003] However, without damaging the wellhead, existing lamp holders are often limited by size and can only be applied to small-diameter pipelines, and it is difficult to enter large-diameter pipelines. As a result, large-diameter drainage pipelines cannot be effectively treated when they need to be repaired, leading to relatively large economic losses.

In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0021] Embodiment: A telescopic lamp holder for LED curing and repair, as Figures 1 - 4 shown, includes a support column 1, a threaded rod 2, a connecting cylinder 3, a rotating handle 4, a connecting block 5, an LED lamp 6 and a supporting component. The threaded rod 2 is slidably connected inside the support column 1, the connecting cylinder 3 is rotatably connected to the top of the support column 1, the connecting cylinder 3 is threadedly connected to the threaded rod 2, the rotating handle 4 is connected to the outside of the connecting cylinder 3, the threaded rod 2 is rotatably connected to the top of the connecting block 5, the LED lamp 6 for curing and repairing pipelines is installed on the top of the connecting block 5, and a supporting component for supporting the device is provided on the support column 1.

[0022] As Figure 1 , Figure 3 and Figure 4 shown, the supporting component includes a lifting ring 7, a lifting cylinder 8, a fixing ring 12, a rotating frame 13, a guiding block 131 and a torsion spring 14. The lifting ring 7 is slidably connected to the upper side of the support column 1, the lifting cylinder 8 is welded to the bottom of the lifting ring 7, the lifting cylinder 8 is slidably connected to the support column 1, the fixing ring 12 is welded to the bottom of the lifting cylinder 8, a plurality of rotating frames 13 are rotatably connected to the fixing ring 12 at intervals along the circumference, the guiding block 131 is connected to the bottom of the support column 1, the rotating frame 13 is in contact and cooperation with the guiding block 131, the top surface of the guiding block 131 is arc-shaped, the inner side of the lower end of the rotating frame 13 is also arc-shaped and fits the guiding block 131, and two torsion springs 14 are connected between the rotating frame 13 and the fixing ring 12.

[0023] As Figure 3 shown, it further includes a pushing block 9 and a return spring 10. The pushing block 9 is slidably connected to the rear side of the lifting ring 7, two return springs 10 are connected between the pushing block 9 and the lifting ring 7, a limiting groove 11 is opened on the rear side wall inside the support column 1, the limiting groove 11 is in the shape of the symbol "[", the pushing block 9 slides linearly along the limiting groove 11 and is in clamping cooperation with the upper and lower ends of the "[", character of the limiting groove 11.

[0024] As Figure 1 and Figure 4 shown, it further includes support blocks 15, rotating blocks 16 and universal wheels 17. Support blocks 15 are connected to the lower ends of the rotating frames 13 by bolts. Rotating blocks 16 are rotatably connected to the support blocks 15. Universal wheels 17 for assisting in moving the device are installed on the rotating blocks 16 by bolts.

[0025] When using the LED lamp 6, the height of the LED lamp 6 can be adjusted according to the usage requirements. During operation, rotate the rotating handle 4 to drive the connecting cylinder 3 to rotate. The connecting cylinder 3 drives the threaded rod 2, the connecting block 5 and the LED lamp 6 to move upward. After adjusting to the appropriate height, stop rotating the rotating handle 4. Rotate the connecting block 5 forward and backward separately to adjust the orientation of the light of the LED lamp 6 to ensure that the light source can accurately irradiate the resin material to be cured. When not in use, lower the height of the LED lamp 6 to make the threaded rod 2 retract into the support column 1, which can save the occupied space of the device in the non-use state. When it is necessary to support the device on the ground, first press the push block 9, and the return spring 10 is compressed accordingly. The push block 9 moves forward and disengages from the upper end of the "[" shape of the limit groove 11, and then the lifting ring 7 can be pushed downward to drive the lifting cylinder 8, the fixed ring 12 and the rotating frame 13 to move downward. The support blocks 15, the rotating blocks 16 and the universal wheels 17 also move downward. The rotating frame 13 will rotate outward and expand due to the arc edge of the guiding block 131, and the torsion spring 14 deforms. When the push block 9 moves down to align with the lower end of the "[" shape of the limit groove 11, the return spring 10 rebounds and resets, causing the push block 9 to move backward and be engaged with the lower end of the "[" shape of the limit groove 11, thus fixing the lifting ring 7. After the rotating frame 13 is expanded, it can directly support on the ground. When it is necessary to horizontally move the device during use, the universal wheels 17 can be rotated outward to drive the rotating blocks 16 to rotate, and the device is supported on the ground by the universal wheels 17, which is convenient for quickly moving the device on the ground and increases the flexibility of use. After use, reverse the above operations to loosen the lifting ring 7, and then the lifting cylinder 8 can be pushed upward to reset, and the torsion spring 14 rebounds and resets to drive the rotating frame 13 to rotate inward and retract.
