Technical Field

[0001] The invention belongs to the field of metal pipe production, and relates to a metal pipe spigot plug loading and unloading tool, and specifically relates to a spigot plug loading and unloading tool used for a large-diameter ductile iron pipe cement lining station. Background Art

[0002] The cement lining station generally adopts a centrifugal rotation method to make the cement mortar evenly adhere to the inner arm of the cast pipe. In order to prevent the cement mortar from splashing during the centrifugal process, a plug needs to be installed on the socket end of the cast pipe. For the socket plug of the cast pipe with a pipe diameter exceeding 1.2m, it is heavy, the manual loading and unloading workload is large, time-consuming, and the production efficiency is low. The document "Cast Pipe Plug Installation Machine" CN 210060313 U provides a plug installation machine, but increases the distance between the mortar distributor and the socket part of the ductile iron pipe, so that the mortar distributor cannot be arranged close to the socket end. In addition, the mortar splashes and leaks to the ground, which is easy to cause the push-pull mechanism to fail. Summary of the invention

[0033] The plug baffle 31 is a flat plate structure perpendicular to the axis of the metal pipe it acts on and is fixed on the driving device; the hook track 32 is two sliding tracks arranged on the outer side of the plug baffle 31 and arranged symmetrically in an upward radial shape; the hook device 40 is symmetrically arranged on the hook track 32 and can move along the hook track relative to the plug baffle 31 to lift, fix and remove the metal pipe socket plug; the plug support plate 34 is protruding and fixed to the bottom of the outer side of the plug baffle 31; the distribution hole 33 is arranged on the plug baffle 31 and penetrates the plug baffle 31, and the distribution hole 33 is located at the lower part of the hook track 32, and the coating material is transported to the inner side of the metal pipe through the distribution hole 33.

[0034] The hook device 40 includes a C-shaped hook 41, a hook driving device 42 and a movable plate 44; the tail end of the C-shaped hook 41 is hinged to the hook driving device 42, and the middle end of the C-shaped hook 41 is rotatably connected to the movable plate 44 by means of a hook fixing seat 45, and the C-shaped hook 41 forms a semi-open cavity 43 that can fix the edge of the plug with the plug baffle 31 through rotation; the hook driving device 42 is rotatably connected to the movable plate 44 by means of a hook driving seat 46, and the driving end is hinged to the C-shaped hook 41 to drive the C-shaped hook to rotate.

[0035] The tail end of the C-shaped hook 41 is bent and extended in the reverse direction toward the hook driving device 42 to form an S-shaped structure. The bending angle of the C-shaped hook 41 is B, and the angle B is 45° to 65°.

[0036] The plug support plate 34 is a V-shaped structure protruding in the opposite direction of the plug, and the two wings of the V-shaped structure match the circumferential outer wall of the plug. The angle between the two wings of the V-shaped structure is A, and the angle A is 130° to 145°. The support frame 10 is provided with a cavity inside to allow the drive device to extend and retract, and two symmetrical sets of drive guide rails 21 are provided on both sides of the cavity. The drive device includes a drive device bracket 24, a sliding wheel group 23 and a push-pull device 22; the drive device bracket 24 is provided inside the support frame 10, and the protruding part is fixedly connected to the inner side of the plug baffle 31; the sliding wheel group 23 is provided inside the drive guide rail 21, fixedly connected to the drive device bracket 24, and supports the drive device bracket 24 to move horizontally relative to the support frame 10; one end of the push-pull device 22 is fixedly connected to the support frame 10, and the driving end is fixedly connected to the drive device bracket 24, driving the drive support frame 24 to move relative to the support frame 10. The sliding wheel group 23 is provided with a rim in the direction toward the inner side of the drive device bracket 24. The hook driving device 42 or the push-pull device 22 includes but is not limited to one of a hydraulic cylinder drive, a motor drive or an electric push rod.

[0037] During specific implementation: when the cast pipe is transported from a station on the production line to the cement lining station, the worker needs to lift the socket plug to the socket side of the production station with an electric hoist. At this time, the C-shaped hook 41 of the hook device 40 on the loading and unloading socket plug device opens outward, and after the worker places the socket plug on the plug baffle 31, the C-shaped hook 41 presses down to fasten the socket plug. Since the C-shaped hook 41 is provided with a bending angle B, and the bending angle B is 45° to 65°, the socket plug is fixed to the plane of the plug baffle 31, limiting its horizontal displacement. When medium and large-caliber socket plugs are installed vertically, due to the deadweight of the plug and the flexibility requirements of the plug itself, the socket plug will generate a certain displacement in the direction of gravity. In order to avoid such a situation, after the C-shaped claw hook 41 is positioned, the claw hook device 40 extends the V-shaped drive track 42 to move upward in the direction of gravity and outward from the center of the plug baffle 31, so that the plug of the socket can gradually restore the shape that matches the socket. At the same time, the C-shaped claw hook 41 is set at an angle to form a cavity between the plug baffle 31, so that the plug of the socket can slide relative to the C-shaped claw hook 41 during the process of restoring the shape, without damaging the plug of the socket. After the push-pull device 22 drives the drive device bracket 24, the plug baffle 31, and the claw device 40 to advance to the socket end of the cast pipe, the C-shaped claw 41 opens outward again, and the push-pull device 22 pulls the drive device bracket 24, the plug baffle 31, and the claw device 40 back to the initial position, and the work of installing the plug of the socket is completed.

[0038] When the cement lining process is completed and the used socket plug needs to be removed, the C-shaped hook 41 opens upward, and the push-pull device 22 drives the drive device bracket 24, the plug baffle 31, and the hook device 40 to advance to the socket end of the cast pipe to the socket plug position, and the C-shaped hook 41 presses down to tighten the socket plug, and the push-pull device 22 drives the drive device bracket 24, the plug baffle 31, and the hook device 40 to pull back to the initial position. After the electric hoist lifts the socket plug, the C-shaped hook 41 opens upward, and the used socket plug is lifted away for cleaning.

[0039] A feeding hole 33 is provided at the bottom of the plug baffle 31 to facilitate the extension and retraction of the feeder pipe. The hook device 40 can be fixed on the hook track 32 in two ways. One way is that the hook device 40 is fixed on the hook track 32 by bolts. When the hook device 40 needs to be moved, the bolts are adjusted to move the position of the hook device 40 on the hook track 32; the other way is that two hook devices 40 are slidably connected to the hook track 32 respectively, and the hook device driver is used to realize the synchronous free sliding of the two on the hook track 32.
