Description

Equipment foundation bolt lengthening method and tightening device Technical Field The invention relates to the technical field of equipment installation, in particular to an equipment foundation bolt lengthening method and a tightening device. Background In petrochemical equipment installation, a large amount of equipment installation needs rag bolt to fix equipment, like tower class equipment, adopts in the concrete foundation pre-buried rag bolt in most, and this kind of rag bolt is pre-buried in equipment foundation reinforcing bar before the foundation concrete placement, forms a whole with the reinforcing bar in the equipment foundation, can bear bigger load, ensures the stability of equipment in the operation in-process. The precision requirement of the tower equipment installation on the foundation bolts is high, the pre-buried foundation bolts have the defects that the pre-buried depth errors are easy to occur in the civil foundation construction or the foundation bolts are improperly protected in the concrete pouring process and the like, so that the bolts move downwards to cause insufficient length of the exposed part of the foundation, and finally the equipment cannot be installed. Disclosure of Invention The invention aims to provide a method for lengthening an anchor bolt of equipment and a screwing device, which are used for solving the problem that the length of a screw rod of an exposed part of a foundation is insufficient due to downward movement of the screw rod caused by various reasons such as easy occurrence of embedded depth errors in civil foundation construction or improper protection of the anchor bolt in a concrete pouring process. The technical scheme includes that the tightening device for lengthening the foundation bolt of the equipment comprises a handle, a mounting ring arranged on the end part of the handle, a lantern ring rotatably arranged in the mounting ring, a sleeve, a locking mechanism and a locking mechanism, wherein the locking mechanism is arranged on the sleeve ring; the outer side wall of the lantern ring is provided with a plurality of groups of grooves, and the mounting ring is provided with inserting blocks in the grooves in a sliding manner; the handle is provided with a pressing block in a sliding manner, and a connecting rope is arranged between the pressing block and the inserting block. Preferably, the inner side wall of the lantern ring is provided with an elastic block, a groove is formed in the elastic block, an air bag is arranged in the groove, and the air bag is communicated with the groove through a connecting pipe.
