Abstract

During the installation of pipes, valves, fittings, or other materials, people tend to neglect to install guides, slides, pipe supports or a misalignment on piping, or create situations where welding is limited. This creates unnecessary work for the installer and considerable cost to the companies to rectify this problem. The installer, pipe fitter or welder must rig chain falls or use cranes to lift pipes or other materials to clear the beams to get enough clearance to install the missing pieces. When taking down old or unnecessary pipes, there may not be enough room to use cutters or other means. Since most pipes run parallel close together on a high line, cutting into another pipe is possible causing rupture, causing rupture, causing harm to workers or plant shutdown. When fitting pipe on a high line, leveling and maneuvering pipe is difficult to do in most instances taking time, machinery and sometimes-unsafe methods to accomplish.

PIPE LIFTER AND LINE UP TOOL

This invention relates to a tool for lifting or adjusting pipes, valves, fittings and other materials. The pipe lifter is a tool that would replace in many instances-chain falls, turfers, cranes or other means. It is a platform that would be attached to a crossbeam either single or double or in a horizontal row to line up pipes for welding, locked at points it would be stable to accommodate the right size of power tools to push the pipe off the beams. The safety fasteners consist of positive locking of the power tool and a safety chain. The bigger the pipe or item that needs to be lifted the bigger the lifting tool gets. It comes in different lifting capacities. For instance, on very heavy pipe, a double lifter can be installed to the same beam. The power tool, which lifts the pipe, incorporates a 'V shaped head or a configuration that would fit the size of pipe. The head has horizontal and vertical rollers that would make the pipe roll on it's own axis or click into place horizontally.

Description

In drawings which illustrate embodiments of the invention:

Figure 1 -shows the side view of a double pipe lifter tool. Figure 2-shows the side view of a single pipe lifter tool. Figure 3-shows the front view of a single pipe-lifting tool. Figure 4-shows the collapsible pipe lifter tool. Figure 5-shows one of the locking devices for a double pipe lifting tool. Figure 6 -shows one of the locking devices for a single pipe lifting tool.

Figure 7-shows a single pipe lifter tool for two sizes of beams. Figure 8-shows the top view of a single pipe lifting tool.

The single pipe lifting tool shown in Fig. 1 comprises of a platform (2), back plate (14), stringers welded or bolted from the outer corners of the platform to the upper corners of the back plate (4). The back plate is cut even with the beam, where the pipe to be lifted is positioned. The horizontal fastening bars (10) would hook onto the opposite side of the beam, sliding through the precut openings through the upper corners of the back plate (17) front view. The universal lifter would be built in such a way as to accommodate several sizes of beams as illustrated on page 7, item 12 and 14 or built to fit each beam separately. The locking devices for the horizontal locking bars could be a combination of ways. Shown are push-through self-locking page 1 , item 8, 9 and page 3 single or double lock devices where bolts and nuts are used.

In order to get a proper lift in a safe manner, the hydraulic jack or other means of lifting have a norm base of the cylinder (1). If height is required, a boosting block could be installed at the base and locked similar as to (1).

For stability of the pipe lifter as a line up tool, the base of the pipe roller page 1-6 is screwed into the top of the cylinder head (7). There is no clearance in the screw assembly for any motion. With increased pipe size the pipe lifter would be built stronger or a double system could be used as shown in drawing 1. On this system, the locking bars would be flat across the beam (10) sliding through each of the back plate slots (17) page 8 and secured by angle fasteners that would be dropped through the openings in the hook bar page 5-18 and secured with bolts and nuts or other fastening devices.

Claims

"The embodiments of the invention in which are exclusive property or privilege is claimed and defined as follows":

1. A manually, pre-automatic, or electrically operable tool that can lift pipes, valves or other materials of a beam comprising of a platform by horizontal hook bars to the opposite side of the beam that supports the pipe.

2. A tool as defined in claim one that has the lifting capacity either by hand, pre-automatic or electric to lift or push an item or pipe of a beam.

3. A tool as defined in claim 1 or claim 2 where the head of the lifting tool is precise enough to enable minute adjustments to height or length of pipe to be lifted.

4. A tool as defined in claim 1 or claim 2 or claim 3 where the tool is doubled up to gain more lifting power and gain greater stability.
