Embodiment Construction

[0014] refer to figure 1 , illustrating the first aspect of the invention by way of example. An apparatus 100 is provided for non-reactive and manual tightening and loosening of a threaded fastener 230 at location 200, reverse socket head screw (SHCS) at pressure seal head 202 of a main stop valve The connection locking part 201. The location 200 includes a tubular rod 210 , a flange 220 and a fastener or socket head screw 230 .

[0015] Apparatus 100 includes lower clamp assembly 110 , upper clamp assembly 120 , reaction adapter assembly 130 , and spring assembly 140 formed between upper clamp assembly 120 and reaction adapter assembly 130 . The lower clamping assembly 110 , eg a fixed clamping member, comprises an annular hollow body 111 having a first portion 112 and a second portion 113 . The first part 112 and the second part 113 are connected on one side by a hinge (not shown) and on the other side by a locking mechanism 114 (eg a set screw). Lower clamp assembly 110...

Abstract

An apparatus for use with a tool assembly in operations of tightening or loosening threaded fasteners (230) about an axis are disclosed, and in one example includes: a lower clamp assembly (110); an upper clamp assembly (120); a reaction adaptor assembly (130); and a spring assembly (140) formed between the upper clamp assembly and the reaction adaptor assembly. Advantageously an operator can tighten or loosen ail fasteners without having to change the initial setup of the apparatus. The lower clamp assembly eliminates the need for extra operators and heavy and bulky equipment to hold the apparatus near the fasteners. The upper clamp allows the operator to rotate the apparatus around with ease. The spring assembly stabilizes and eases vertical height adjustment of the apparatus. The reaction adaptor substantially negates reaction turning forces of the tool assembly during the operation. Drive knobs (312, 322) provide easy alignment of and quick and safe mounting of the tool assembly (310, 320) on the fasteners. Bolting operation about an axis is completed faster, cheaper and with little or no risk of operator injury.
