Description

Blind flange transferring clamp

Technical Field

The utility model relates to a jack-up auxiliary device field, especially a blind flange transports anchor clamps.

Background

The blind flange is also called as a blind flange or a blind plate, namely a flange without holes, is a connection form of the flange, has the main function of blocking the tail end of a pipeline, can conveniently remove impurities in the pipeline during maintenance, acts on a seal head and a pipe cap in the pipeline similarly, but the seal head and the pipe cap are difficult to disassemble, and the blind flange is fixed by bolts and can be conveniently disassembled by the tightness of the bolts, so that the blind flange is widely applied to occasions needing to disassemble; under the condition of pipe diameter increase, the also corresponding increase of blind flange, little blind flange manual operation is fairly simple, can conveniently carry the transfer, carries out other processing etc. but a lot of big blind flanges weight is heavier, and the diameter is big again, and the centre gripping is very difficult, does not hoist before punching also too easily, relies on the manual work to go up unloading, transports etc. under most circumstances, has caused certain potential safety hazard.

The existing blind flange clamp is used for clamping during outer diameter machining, and the specific structure is as the patent of Chinese utility model: a tool clamp (No. CN206578311U) for processing the outer diameter of a finished blind flange comprises a flange fixing tool and a flange jacking tool, wherein the flange fixing tool comprises an annular bottom plate and a fastening pin, the fastening pin is arranged on the annular bottom plate and matched with a bolt hole of the flange, one end of the flange jacking tool is connected with the flange, and the other end of the flange jacking tool is provided with a hole and is sleeved on the top of a machine tool through the hole; the original processing mode of connecting two blind flanges through bolts and clamping one blind flange is changed into the processing mode of clamping the blind flange by using the tool, so that the time and labor consumed by bolt connection are reduced, the quick clamping and quick processing of the blind flange are realized, and the repair efficiency is improved; the fixture can position the blind flange so that the blind flange is not displaced during processing, but the fixture is difficult to move the blind flange.

In addition, a hoisting tool is provided, for example, the invention patent application in China: the auxiliary tool for hoisting the blind plate (application publication number: CN109733982A) comprises a pair of clamping plates, a hoisting point bolt nut pair and a perforated bolt nut pair, wherein the clamping plates are oppositely arranged, and the hoisting point bolt nut pair and the perforated bolt nut pair are arranged on the clamping plates; the fixed hoisting point bolt and nut pairs and the fixed perforated bolt and nut pairs and the clamping plate form a # -shaped structure. The auxiliary blind plate can be quickly and conveniently hoisted, so that the hoisting efficiency is greatly improved; moreover, the abrasion problem of the steel wire rope is avoided, and the potential safety hazard is avoided; meanwhile, the hoisting device is also suitable for hoisting other large-scale blind plates and flanges; the hoisting tool also depends on the screw holes on the blind plate to hoist the blind plate, and the non-punched blind plate of the semi-finished product cannot be hoisted at all.

Therefore, there is a need for further improvements in the fixtures used for blank flanges for semi-finished products.
