Background

The pipelines of a plurality of devices in chemical production generally have flammable and explosive or easily corroded gases and liquids, and when the modified devices are overhauled or replaced, the pipelines must be safely isolated, so that the operation safety of overhauling or modifying can be ensured. It is a conventional practice to apply a blind flange, i.e. a flange cover, to the joint of the pipe flanges for the isolation and sealing process. However, in actual operation, due to the influence of the gravity or stress of the pipeline, the flange bolt is removed, and then the flange interface end face is misplaced, so that the flange cannot be completely aligned, the bolt cannot be inserted during installation, the flange face is easily damaged, or a gasket in the flange cannot be placed in place, the installation precision is insufficient, and leakage is easily caused in the later stage.

Therefore, the bolts need to be fastened after aligning the flanges. The existing method is that the prying bar is inserted into an upper flange bolt hole and a lower flange bolt hole, the flange plate is aligned through manual correction, time and labor are wasted, the installation quality cannot be guaranteed, the prying bar slides down to cause falling and flash injury of workers, and great potential safety hazards exist.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing a pipeline flange correction instrument through mutually supporting of locating pin and correction screw rod to lower one end flange location compresses tightly higher one end flange and corrects labour saving and time saving, and the operation is safe, with the current artifical problem of correcting wasting time and energy, unsafe of solving.

In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a pipeline flange corrects instrument, includes bottom plate and end plate, the end plate set up in bottom plate lower surface one end, and this end plate upper level is provided with the locating pin, locating pin one end is fixed the end plate is kept away from one side of bottom plate, the other end passes and stretches out the end plate, the bottom plate upper surface is rotated and is provided with the correction screw rod, the vertical setting of correction screw rod and its bottom pass and stretch out the bottom plate.

In the above technical scheme, a sliding groove is arranged on the bottom plate along the length direction of the bottom plate, and the bottom end of the correcting screw rod penetrates through the sliding groove and is arranged in the sliding groove in a sliding manner.

In the above technical scheme, the correcting screw rod is locked by the fixing nuts respectively positioned on the upper surface and the lower surface of the bottom plate.

In the technical scheme, a handle is arranged at the top end of the correcting screw rod, and the handle is sleeved on the correcting screw rod through a handle sleeve.

In the technical scheme, the bottom plate and the end plate are connected in a welding mode and form an L-shaped structure.

In the above technical scheme, the positioning pin is fixedly connected with the end plate through a locking nut.

The utility model has the advantages that: the utility model relates to a rationally, inject the lower one end flange through the locating pin and go up the location, correct the screw rod and rotate the butt and correct on higher one end flange and compress tightly this end flange, simple structure, the simple operation has improved the security of workman's operation, is favorable to save time and guarantees subsequent installation quality. In addition, adjust the relative distance of correcting screw rod and locating pin through setting up the spout, can satisfy the correction of the pipe connection flange of different intervals, enlarged the utility model discloses an application range, economical and practical.

Detailed Description

The invention will be described in further detail with reference to the following drawings and specific embodiments:

As shown in fig. 1 to 3, a pipe flange straightening tool comprises a bottom plate 1 and an end plate 2, wherein the end plate 1 is welded at one end of the lower surface of the bottom plate 2, so as to ensure firm connection and be used for being matched with a positioning pin for positioning. The end plate 1 is horizontally provided with a positioning pin 4, one end of the positioning pin is fixed on one side of the end plate 1 far away from the bottom plate 2 through a locking nut 3, and the other end of the positioning pin penetrates through and extends out of the end plate 1 and is used for being inserted into a top flange hole of a lower end flange 9 for positioning during correction. The upper surface of the bottom plate 2 is provided with a correcting screw 5 in a rotating and vertical mode, the top end of the correcting screw 5 is sleeved with a handle sleeve, the handle sleeve is connected with a handle 7, the bottom end of the correcting screw 5 penetrates through the bottom plate 2 and extends out of the bottom plate, so that the correcting screw 5 can be conveniently rotated by the handle 7 to move forwards towards the flange 10 at the higher end in the correcting process, the bottom end of the correcting screw 5 is abutted against the flange 10 at the higher end and then continuously rotates, and the flange 10 at the higher end is further pressed downwards so that flanges at two ends are aligned to achieve the correcting purpose.

In this embodiment, be provided with spout 8 along its length direction on bottom plate 2, this spout 8 is passed to correction screw rod 5 bottom, can be in spout 8 round trip movement, and through being located bottom plate 2 respectively upper and lower surface's fixation nut 6 locking fixed, in order to form slide mechanism, can adjust the relative distance of correction screw rod 5 and locating pin 4 and fix through fixation nut 6 locking during the use according to the actual distance between the both ends flange of different pipe connection departments, thereby enlarge the utility model discloses an application range, improve economic benefits, and the threaded connection between correction screw rod 5 and fixation nut 6 can make correction screw rod 5 just rotate to higher one end flange 10, thereby compress tightly higher one end flange 10 downwards and make the both ends flange align and reach the purpose of correcting.

the utility model discloses a use method: the utility model discloses during the use, insert the top flange hole of lower one end flange 9 with locating pin 4 earlier, loosen two fixation nut 6 and correct the position of screw rod 5 according to the position slide adjustment of higher one end flange 10, make the bottom of correcting screw rod 5 aim at behind the higher one end flange 10 two fixation nut 6 of relocking, make and correct screw rod 5 rigidity, later operating handle 7 makes and corrects screw rod 5 and rotates to the direction of higher one end flange 10, it can to compress tightly higher one end flange 10 and align the correction.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
