Description

Technical Field

[0001] The utility model relates to the technical field of pipeline repair, in particular to a manhole wellhead hoisting device for repairing a CIPP pipeline. Background Art

[0002] CIPP is a pipe repair technology that involves dragging a non-woven or fiberglass lined pipe soaked in resin into the pipe, then pumping air into the pipe to prop it up, and then using ultraviolet light to cure the resin. Once the pipe is cured, a new pipe is formed inside the original pipe.

[0003] During the above pipeline repair process, it is necessary to hang the equipment, liner pipe, tying head or ultraviolet lamp for clearing the pipeline into the inspection well.

[0004] The patent document with application number CN202020734959.9 discloses a wellhead lifting device for CIPP pipeline repair. A limit plate that can be adapted to the inner wall of the wellhead body is added to the lower end of the construction personnel's support rod. The construction personnel can fix the support rod to the upper end of the wellhead body through the limit plate, and drive the rotating sleeve to rotate, thereby driving the stud and the stroke block to move upward. During the upward movement of the stroke block, the support rod will be pushed to expand, thereby increasing the outer diameter of the lower end of the support rod, so that the pressure between the support rod and the limit plate and the inner wall of the wellhead body gradually increases, thereby fixing the support rod and the limit plate more firmly to the upper inner wall of the wellhead body. In order to be able to stably lift the equipment, the device must have at least three support rods. However, when the diameter of the pipe to be repaired is large, the size of the unblocking equipment, liner pipe, piercing head or ultraviolet lamp used therewith increases accordingly. When lowering the unblocking equipment, liner pipe, piercing head or ultraviolet lamp into the inspection well, it is inconvenient to pass through the gaps between the support rods. Therefore, the device cannot lift larger pipeline repair equipment. Utility Model Content

Specifically, a support plate 15 is fixed to the end of the upper rod 8 away from the turntable 7, a connecting rod 14 is rotatably connected to the supporting plate 15, and the connecting rod 14 is fixedly connected to the supporting rod 11. The connecting rod 14 is in an inverted L shape, the vertical part of the connecting rod 14 is rotatably connected to the supporting plate 15 through a pin, and the straight part of the connecting rod 14 is fixedly connected to the supporting rod 11.

[0043] A groove 9 is formed at the upper end of the second ear plate 301, and the lower end of the support rod 11 can enter the groove 9 after rotating to a vertical state. A blocking rod 10 is provided on the second ear plate 301, and the blocking rod 10 passes through the groove 9, and the blocking rod 10 can block the support rod 11 part in the groove 9.

[0044] When installing the device, the two arc plates 2 are located inside the wellhead of the inspection well 1, and the first ear plate 3 and the second ear plate 301 are in contact with the ground outside the wellhead of the inspection well 1. Then the double-ended screw 5 is rotated to move the two arc plates 2 away from each other, so that the arc plates 2 are pressed against the upper end of the well wall of the inspection well 1. In order to improve the stability of the device during operation, an arc plate 2 with a suitable curvature is selected, so that the arc plate 2 is pressed against the upper end of the well wall of the inspection well 1, and then the arc plate 2 is concentric with the wellhead of the inspection well 1. At this time, the outer edge of the arc plate 2 is in contact with the upper end of the well wall of the inspection well 1 as a whole, which can improve the stability of the device during operation.
