Abstract

The utility model belongs to the field of pipeline disassembling tools, in particular to a pipeline disassembling tool, which solves the problems that when the pipeline is disassembled by using a traditional pipe wrench, the pipeline can not be effectively operated at a narrow part and only a longer pipeline can be replaced, thereby causing low working efficiency, influencing the overhaul progress and having high maintenance cost, and comprises a chain, a nut, a bolt and a clip; a nut is fixed in the middle of the chain, two free ends of the chain are a left end opening and a right end opening, and the left end opening and the right end opening of the chain are bent to form a closed ring; the starting end of the screw thread of the nut faces outwards, and the bolt is inserted in the nut; the checkpost is located the outer side of outer chain piece, and left end mouth and the right-hand member mouth of chain pass through the checkpost to be fixed. The utility model is simple, light, convenient to carry, simple to operate and convenient to operate in narrow space; the work efficiency is improved, the overhaul progress is accelerated, and the maintenance cost is reduced.

Description

Pipeline extracting tool

Technical Field

The utility model belongs to pipeline extracting tool field, concretely relates to pipeline extracting tool.

Background

My factory is a novel modernized modular coal washing factory, and the washing and selecting system process is as follows: the method is a combined process flow of adopting a heavy-medium shallow groove to sort 100-13 mm lump coal, adopting a pressure two-product heavy-medium cyclone to sort 13-1.5 mm slack coal, adopting a spiral sorting machine to sort 1.5-0.5 mm coarse coal slime, and adopting a filter press to directly recycle less than 0.5mm fine coal slime.

In the washing process, closed circulation is realized by using pipelines, and meanwhile, according to the requirements of a coal washing system, a medium pipeline, a coal slime pipeline, an air pipeline and a circulating water pipeline are mainly arranged, and various pipelines are made of iron products, and need to be replaced periodically when being corroded by water and media for a long time so as to ensure normal production. In the prior art, when a pipeline is replaced, a pipe wrench cannot effectively work at a narrow part, and only a long pipeline can be replaced. According to the needs of the process, the diameters of the arranged pipelines have different sizes of 25mm, 50mm, 75mm and 100mm, so that the replacement time is long, and materials are wasted. Therefore, according to the actual situation on site, a simple tool is expected to be assembled and manufactured by using the waste chains, and the pipeline can be conveniently disassembled.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the tradition and use the breakout tongs when dismantling the pipeline, can not effectively operate at narrow and small position, can only change longer pipeline to lead to work efficiency low, influence to overhaul the problem that progress, cost of maintenance are high, provide a pipeline extracting tool.

The utility model adopts the following technical proposal: a pipeline disassembling tool comprises a chain, a nut, a bolt and a clamp;

a nut is fixed in the middle of the chain, two free ends of the chain are a left end opening and a right end opening, and the left end opening and the right end opening of the chain are bent to form a closed ring;

the starting end of the thread of the nut faces outwards, and the bolt is inserted into the nut;

the checkpost is located the outer side of outer chain piece, and left end mouth and the right-hand member mouth of chain pass through the checkpost to be fixed.

Furthermore, the outer sides of the other outer chain sheets of the chain are connected through riveting.

The utility model discloses compare prior art's beneficial effect:

the utility model adopts the welding nuts at the two ends of the waste chain and the matching bolts to disassemble and install the pipeline, so the utility model has the advantages of low manufacturing cost, simplicity, lightness, convenient carrying, simple operation and convenient operation in a narrow space; use the breakout tongs to change 25 mm's pipeline in the past, need to change longer pipeline, change and once need 3 hours, use now the utility model discloses only change one section pipeline of damage, 30 minutes can the operation finish, and is thus visible the utility model discloses work efficiency improves, accelerates maintenance progress, cost of maintenance to reduce.

Drawings

FIG. 1 is a schematic view of the present invention;

in the figure: 1-chain, 2-nut, 3-bolt and 4-clip.

Detailed Description

The embodiments of the present invention will be further explained with reference to the accompanying drawings:

referring to fig. 1, the utility model provides a pipeline disassembling tool, which comprises a chain 1, a nut 2, a bolt 3 and a clip 4;

a nut 2 is fixed in the middle of the chain 1, two free ends of the chain 1 are a left end opening and a right end opening, and the left end opening and the right end opening of the chain 1 are bent to form a closed ring;

the starting end of the thread of the nut 2 faces outwards, and the bolt 3 is inserted into the nut 2;

the checkpost is located the outer side of outer chain piece, and left end mouth and the right-hand member mouth of chain 1 pass through checkpost 4 fixedly.

The outer sides of the other outer chain sheets of the chain 1 are connected through riveting.

The utility model is a disassembling tool designed for pipelines with the diameter of 25mm, and a set of chain sections matched with pipelines with other diameters are additionally prepared; when changing the pipeline of all the other specifications, then the utility model discloses a connect the chain section that this pipeline diameter corresponds on the basis can.

The utility model discloses an application example:

when the pipeline needs to be replaced, firstly, the bolt is withdrawn to the bottommost end; secondly, removing the clips 4 to break the chain 1; thirdly, the disconnected chain 1 sleeves the pipeline; fourthly, the broken chain 1 is re-installed together, and the clip 4 is fixed at the outer side of the outer chain plate; fifthly, screwing the bolt 3 until the end part of the bolt 3 props against the pipeline; sixthly, the head of the bolt 3 is held by hand to rotate so as to disassemble the pipeline.
