Pipeline joint maintenance equipment

Abstract

The utility model discloses pipeline joint maintenance equipment which comprises two pipelines arranged in a bilateral symmetry mode, a connecting pipeline arranged between the ends, close to each other, of the pipelines in a sleeved mode and a pipeline maintenance instrument tightly holding the outer surfaces of the pipelines. The pipeline maintenance instrument comprises two pipe body embracing rings locked on the surface of the outer ring of the pipeline, screw pipes fixed to the side walls of the front faces of the pipe body embracing rings and screw rods transversely penetrating through the screw pipes, and crankshafts are fixed to the ends, close to each other, of the screw rods. According to the technical scheme, the pipeline overhauling instrument is arranged between the two pipelines to be butted, the pipelines are tightly held by the hoops at the two ends of the instrument, the visible laser transmitter and the target plate are arranged at the bottoms of the hoops respectively, and the pipelines can be overhauled through traction limitation of the crankshaft and the screw rod on the hoops. And meanwhile, the visual laser transmitter and the target plate assist in enabling the pipelines to be coaxially arranged, so that a gap between the pipelines and the inner cavity of the three-way pipe is reduced when the pipelines are oppositely inserted and mounted.

Description

Technical Field

[0001] The utility model relates to the technical field of pipeline repair equipment, in particular to a pipeline joint repair device. Background Art

[0002] After checking for leakage at the pipe joint, the connecting pipe between the two pipes is usually removed, and after replacing the connecting pipe, the two pipe ends are inserted into the connecting pipe, and the inside of the connecting pipe or the outer ring of the pipe is usually wrapped with raw tape to seal the gap between the three. However, in the process of inserting the pipe into the connecting pipe, the pipes need to be inserted into the connecting pipe one by one, and the two pipes cannot be inserted simultaneously. Moreover, when the pipes are coaxial with each other and have a large error, the part of the pipe end located inside the connecting pipe is skewed, which not only makes it difficult to plug in, but also easily leads to a large gap between the pipes, thereby causing leakage at the position with a large gap. Therefore, those skilled in the art propose a pipe joint inspection device. Utility Model Content

[0003] The utility model aims to provide a pipeline joint maintenance device to solve the shortcomings mentioned in the background technology.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] In this technical solution, a pipeline inspection device is arranged between two pipelines to be butt-jointed, and the pipelines are clamped by clamps at both ends of the device, and a visible laser emitter and a target plate are respectively arranged at the bottom of the clamps. The traction of the clamps is limited by a crankshaft and a screw, and the visible laser emitter and the target plate assist in coaxial arrangement of the pipelines, thereby reducing the gap between the pipelines and the inner cavity of the tee pipe when the pipelines are plugged in and installed.

[0023] Example

[0024] Refer to the instruction manual Figure 1 To Attachment Figure 3 As shown;

[0025] The best technical solution for pipeline joint maintenance equipment:

[0026] The present embodiment includes: two pipes 1 arranged symmetrically on the left and right, a connecting pipe 2 sleeved between the ends of the pipes 1 close to each other, and a pipe repair tool 3 clamped on the outer surface of the pipe 1; the pipe repair tool 3 includes two pipe body rings 31 locked on the outer ring surface of the pipe 1, a spiral tube 39 fixed on the front side wall of the pipe body ring 31, and a screw rod 38 transversely passing through the inside of the spiral tube 39, and a crankshaft 310 is fixed on the end of the screw rod 38 close to each other.

[0027] A target plate 37 is fixed to the bottom surface of the left tube body ring 31 , and a visible laser emitter 311 is fixed to the bottom surface of the right tube body ring 31 , and the target plate 37 and the visible laser emitter 311 are coaxially arranged.

[0028] The inner cavity side wall of the tube body holding ring 31 is fixed with a rubber bushing 36 by adhesive, and the inner ring side wall of the rubber bushing 36 is provided with a plurality of anti-slip grooves 35. The tube body holding ring 31 is in a "C" shape as a whole, and a convex block 32 is fixed at both ends of the tube body holding ring 31, and a locking screw 33 is penetrated inside the convex block 32, and a through hole for the locking screw 33 to penetrate is provided inside the convex block 32.

[0029] The locking screw 33 is sleeved with a nut 34 on the section outside the through hole of the protrusion 32, and a gasket is provided on the side wall of the nut 34 to contact the outer side wall of the protrusion 32. A connecting rod 312 is fixed on the front side wall of the tube body ring 31, and the end of the connecting rod 312 away from the tube body ring 31 is fixedly connected to the side wall of the screw tube 39. The inside of the screw tube 39 is provided with a threaded hole adapted to the screw rod 38, and the outer ring surface of the screw rod 38 is provided with a thread with the opposite direction of the spiral.

[0030] According to the above-mentioned preferred technical solution, the workflow of the technical solution is described as follows:

[0031] By rotating the crankshaft 310, the screw tubes 39 on the screw rod 38 are moved away from each other. At the same time, the nut 34 on the pipe body ring 31 is unfastened and the locking screw rod 33 is pulled out. After the opening of the pipe body ring 31 is passed through the outer ring of the pipe 1, the locking screw rod 33 is passed through the protrusion 32 again and the nut 34 is locked. Under the cooperation of the rubber bushing 36 and the anti-skid groove 35, the pipe body ring 31 is tightly locked on the outer ring of the pipe 1. Since the pipe body ring 31, the connecting rod 312, the screw rod 38 and the crankshaft 310 form a whole, the two pipes 1 are pulled at this time, and the two pipes 1 can be as coaxial as possible. At this time, the light emitted by the visible laser emitter 311 irradiates the target plate 37, and the screw rod 38 is driven to rotate by the reverse rotation of the crankshaft 310. At this time, the screw tubes 39 move closer to each other, and under the pulling action of the screw tubes 39 and the connecting rod 312, the two pipes 1 slowly approach and are plugged into the two ends of the connecting pipe 2.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
