Embodiment Construction

[0014] refer to figure 1 , illustrating the first aspect of the invention by way of example. An apparatus 100 is provided for counter-force 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 . A lower clamping assembly 110 (eg, a stationary clamp) includes 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 is non...

Abstract

An apparatus for use by a tool assembly in performing operations about an axis to tighten or loosen threaded fasteners, and in one example, the apparatus includes: a lower clamping assembly (110); an upper clamping assembly (120); a reaction an adapter assembly (130); and a spring assembly (140) formed between the upper clamp assembly and the reaction adapter assembly. Advantageously, the operator can tighten or loosen all fasteners without changing the initial setup of the device. The lower clamping assembly avoids the need for additional operators and heavy and bulky equipment to hold the equipment near the fasteners. The upper clamping assembly allows the operator to easily rotate the equipment. The spring assembly makes the device stable and easy to adjust the vertical height of the device. The reaction adapter generally counteracts reaction rotational forces of the tool assembly during operation. The drive head (312, 322) allows the tool assembly (310, 320) to be easily aligned with the fastener and installed thereon quickly and safely. Tightening operations around an axis can be accomplished faster, cheaper and with little or no risk of injury to the operator.
