Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the described embodiments are merely exemplary of the utility model, and not restrictive of the full scope of the utility model. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

As shown in fig. 1 to 3, a tool for rapidly replacing a blind plate according to a preferred embodiment of the present invention includes a wheel extractor 1, and a top plate 4 connected to a blind plate 5, wherein a thimble 2 of the wheel extractor 1 is used for driving a grinding head 6 disposed between the top plate 4 and the blind plate 5 to move towards the blind plate 5, and the grinding head 6 is used for contacting the blind plate 5 to effectively avoid wear of the wheel extractor 1.

When the tool for quickly replacing the blind plate is applied, the workload of workers can be reduced to the maximum extent, under the normal condition, 8 minutes are expected to be needed for installing one blind plate 5 (4 bolt assemblies in total and 8 bolts in total), if the tool is used, the operation can be completed only by screwing the wheel puller 1 for 1 minute, and the test efficiency can be greatly improved.

On the basis of the above-described embodiment, the wheel puller 1 may be selected from the three-jaw wheel puller 1, but is not limited to this.

On the basis of the above embodiment, the large-diameter end of the grinding head 6 contacting the blind plate 5 is a spherical surface, and more specifically, the top plate 4 is provided with a through hole 8 for accommodating the small-diameter end of the grinding head 6, and the small-diameter end of the grinding head 6 is in sliding fit with the through hole 8 so that the small-diameter end of the grinding head 6 protrudes out, and the thimble 2 abuts against the end of the small-diameter end of the grinding head 6.

When the handle of the wheel puller 1 is rotated, the ejector pin 2 provides forward rotating force for the grinding head 6, the grinding head 6 provides forward rotating force for the blind plate 5, the top of the ejector pin 2 is small, and the grinding head 6 is of a spherical structure, so that the provided rotating force is very small, the structure can ensure that the rotating torque force between the blind plate 5 and the flange at the pipe orifice of the pipeline to be plugged is very small, the blind plate 5 and the flange cannot twist, and the air tightness between the blind plate 5 and the flange is ensured.

On the basis of the above embodiment, the diameter size of the large-diameter end of the grinding head 6 is larger than that of the through hole 8, so that the grinding head 6 is limited between the blind plate 5 and the fixed plate and is prevented from falling.

For better technical effect, in the above embodiment, the top plate 4 and the blind plate 5 are detachably connected, and specifically, the top plate 4 is connected with the blind plate 5 through a plurality of bolts so as to facilitate the loading and unloading of the grinding head 6.

And the blind plate 5 is provided with a threaded blind hole 7 for matching with a bolt, so that the influence of a threaded through hole 8 on the sealing performance of the blind plate 5 after being slightly dislocated with the flange is avoided.

It should be noted that, the installation process is:

1) 3 pulling claws 3 on the pulley puller 1 pull the flange;

2) the blind plate 5 is used for blocking the flange hole (namely the pipe orifice);

3) the rod on the mechanism of the wheel puller 1 is rotated by hand, and the thimble 2 is screwed clockwise.

The disassembly process is as follows:

1) rotating a rod on a mechanism of the wheel puller 1 by hand, and unscrewing the thimble 2 anticlockwise;

2) and 3 pulling claws 3 on the pulley extractor 1 are detached from the flange.

Finally, it should also be noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
