Abstract

The utility model relates to a chain-type pipe cutter which is used for cutting and repairing the pipe with a large diameter. The cutting part of the pipe cutter is composed of a plurality of cutters, wherein each cutter and the adjacent cutter are assembled and connected by a pin and a chain slice to form a chain-type cutter which can circle the pipe wall. A screw rod is arranged in a handle, the front end of the screw rod is provided with a chain hook, and the rear end of the screw rod extends out of the tail end of the handle and is provided with a rotary handle. One end of the chain is fixed on one side of a V-shaped bracket of the front end of the handle, and the other end is hung on the chain hook in the handle by passing round the pipe. The utility model is very suitable for combustible and explosive occasions.

Description

The chain-type pipe cutter

The utility model is the cutting tool that a kind of pipeliner uses, and is used for the cut-out maintenance of big-inch pipe.

In the present pipeline installation and maintenance, diameter generally cuts with existing pipe cutter less than 80 millimeters pipe, and diameter then cuts with handsaw, abrasive wheel cutting machine or cutting torch greater than 80 millimeters pipe.In many maintenance sites, because the restriction in space can only be used the cutting torch cutting.But in inflammable, explosive place, cutting torch can't use, and makes troubles to maintenance operation.

The utility model is exactly a kind of big-inch pipe cutting tool at the problems referred to above design, satisfies the requirement that special occasions uses.

The utility model is a kind of chain-type pipe cutter, by the disk cutter, and handle, screw rod and composition such as guide locating device provided.The cutting part of pipe cutter is combined by a plurality of cutteves, and the cutter that each cutter is adjacent connects with pin, the assembling of chain sheet, and composition can be around the chain-type cutter of tube wall; Pin is contained in the axis hole of disk cutter, and the chain sheet is clipped in the cutter both sides and is through on the pin cutter is combined.Handle is a hollow tubular, and front end is the V-type support, and guide pad is housed, and guide pad is positioned at the cutter both sides, supports the chain sheet of both sides.A screw rod is equipped with in handle inside, screw front end is equipped with a chain hook, spiro rod rear end stretches out the handle tail end, and a swing handle is housed: chain one end is fixed on V-shaped rest one side of handle front end, the other end is walked around pipe and is hung on the interior chain hook of handle, on the pipe of cutter both sides guide ring is housed during use, guide ring is two semicircles, and there is the Bolt Connection hole at the half-circular cutouts place.Guide ring is fixed on the pipe, and the chain-type cutter is walked around pipe and is hung on the chain hook, constantly screws swing handle on the handle and the low-angle handle that swings back and forth, and cutter rolls around pipe and just can gradually pipe be cut off.

The utility model can solve the instructions for use that special inflammable, explosive occasion is cut off big-inch pipe, carries and uses all very conveniently, is well suited for oil, gas field, natural gas, coal gas, and field work and some maintenance occasion are cut off large-diameter pipeline and are used.

Accompanying drawing 1 is a structural representation of the present utility model, and handle is anterior for cutting shape open.

Accompanying drawing 2 is structural representations of the guide ring of the utility model use.

The utility model is a kind of chain-type pipe cutter, cutter adopts existing disk cutter 7, the cutting part of pipe cutter is combined by a plurality of cutteves 7, the cutter that each cutter is adjacent connects with pin 9,8 assemblings of chain sheet, composition can be around the chain-type cutter of tube wall: the quantity of blade 7 can be installed and removed according to pipe diameter, and the pipe diameter that can cut is that 76mm is up to 219mm.For cutting 156mm pipe, 17 blades have been assembled shown in the figure.Pin 9 is contained in the axis hole of disk cutter 7, and chain sheet 8 is clipped in cutter 7 both sides and is through on the pin 9 cutter is combined.Handle 2 adopts square hollow steel pipe, and front end is a V-type support 6, and guide pad 5 is housed, and guide pad 5 is positioned at cutter 7 both sides, supports the chain sheet 8 of both sides.A screw rod 3 is equipped with in handle 2 inside, screw rod 3 front ends are equipped with a chain hook 4, handle 2 tail ends are stretched out in screw rod 2 rear ends, and a swing handle 1 is housed: chain one end is fixed on V-shaped rest 6 one sides of handle 2 front ends, the other end is walked around pipe and is hung on the chains hook 4 in the handle 2, guide ring 10 is housed on the pipe of cutter both sides during use, and guide ring 10 is two semicircles, and there are bolt 11 connection holes at the half-circular cutouts place.Guide ring 10 is fixed on the pipe, and the chain-type cutter is walked around pipe and is hung on the chain hook 4, constantly screws the handle 2 that swings back and forth about swing handle 1 on the handle 2 and 90 degree, and cutter rolls around pipe and just can gradually pipe be cut off.
