Abstract
The utility model provides a kind of piston rod nut extracting tool.The piston rod nut extracting tool of the utility model, it is characterized in that: including handle, opening head, connection neck, the opening head is mounted on the handle by connecting neck, the axis of the handle and the connection neck is in 30 ° of angles, on same straight line, the width of the opening of the opening head is greater than the major diameter of piston rod thread and is less than piston rod nut with respect to the distance between two sides the axis of the center of the opening head and the connection neck.The utility model principle selection is ingenious, simple and reliable for structure, can effectively dismantle, improve labor efficiency to piston rod nut.
Description
Technical field:
The utility model relates to a kind of piston rod nut extracting tools, belong to flight-line maintenance equipment technical field.
Background technique:
Piston compressor, be widely used in gas compression utilize and provide power production system, as in system not
The power-equipment that can lack controls its failure rate, improves its overhaul efficiency and effect, can improve production efficiency, while reduction pair
The loss of standby redundancy has preferable economic benefit.When dismantling piston rod nut using original extracting tool, due to its contact
Face is few, and contact area is smaller, when leading to disassembly, causes piston rod nut to deform because stress is excessive, extracting tool loses
The situations such as the phenomenon that effect is obstructed so as to cause the maintenance of compressor, and follow-up work must not be carried out, are usually taken at this time to piston rod
Nut is heated, and expansion is brought it about, and gap increases between piston rod, to obtain the effect of loosening, due to
Compressor internal actions operation, there are more security risk, preparation is cumbersome, it is therefore necessary to service kit improved,
Reduce the special operation method taken because dismantling piston rod nut.
Utility model content:
The purpose of this utility model is to provide a kind of piston rod nut extracting tool, the device in view of the above problems
Principle selection is ingenious, simple and reliable for structure, can effectively dismantle, improve labor efficiency to piston rod nut.
Above-mentioned purpose is realized by following technical scheme:
A kind of piston rod nut extracting tool, including handle, opening head, connection neck, the opening head pass through connection neck peace
On the handle, the axis of the handle and the connection neck is in 30 ° of angles, the center of the opening head and the connection
On same straight line, the width of the opening of the opening head is greater than the major diameter of piston rod thread and is less than piston rod the axis of neck
Nut is with respect to the distance between two sides.
The opening inner side of the piston rod nut extracting tool, the opening head is provided with corresponding piston rod nut side
Arris has strip.
The piston rod nut extracting tool, the handle, opening head, connection neck are in be integrally cast.
The piston rod nut extracting tool, the thickness of the handle are not less than 12mm, the thickness on the opening head
Degree is not less than 15mm.
The length of the piston rod nut extracting tool, the connection neck is 30-100mm.
The utility model has the advantages that
1. the width of the opening of the opening head of the utility model is greater than the major diameter of piston rod thread and is less than piston rod nut
The contact area of piston rod nut extracting tool is improved on the distance between opposite two sides, can be from when dismantling piston rod nut
It is inserted at piston rod and cap forward bolt piston bar, then by the tool cover on piston rod nut, improves its contact area, reduced to work
The damage of stopper rod nut.
2. considering to carrying out disassembly piston rod nut, limited space system, the hand of the utility model in the slideway of compressor
The axis of handle and the connection neck is in 30 ° of angles, can effectively improve operation freedom degree, be conducive to the operation width for protecting labourer
Degree, improves labor efficiency.
3. the utility model use material be chrome-vanadium steel (Cr-V), hardness can be higher after heat treatment, up to 60HRC with
On, toughness is to greatly improve, and more resistant to impact and abrasion, the service life is longer.
4. the utility model by thickening its opening, at handle material thickness, improve its mechanical property.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, handle；2, be open head；3, neck is connected；4, strip.
Specific embodiment:
The piston rod nut extracting tool of the present embodiment as shown in Figure 1:, including handle 1, opening head 2, connection neck 3, it is described
Opening head is mounted on the handle by connecting neck, and the axis of the handle and the connection neck is in 30 ° of angles, the opening
For the axis of the center of head and the connection neck on same straight line, the width of the opening of the opening head is greater than piston rod thread
Major diameter and be less than piston rod nut with respect to the distance between two sides.
The opening inner side of the piston rod nut extracting tool, the opening head is provided with corresponding piston rod nut side
Arris has strip 4.During use, due to the barrier effect of strip, enables extracting tool to stick into nut and be not easy to slide
It is dynamic, it works relatively reliable.
The piston rod nut extracting tool, the handle, opening head, connection neck are in be integrally cast, structure
Stability is good, and the material of utilization is chrome-vanadium steel (Cr-V), and hardness can be higher after heat treatment, and up to 60HRC or more, toughness is significantly
It improves, more resistant to impact and abrasion, the service life is longer.
The piston rod nut extracting tool, the thickness of the handle are not less than 12mm, the thickness on the opening head
Degree is not less than 15mm.
The length of the piston rod nut extracting tool, the connection neck is 30-100mm.
Technological means disclosed in the utility model is not limited to the technical means disclosed in the above technical means, also
Including the technical solution as composed by the above technical characteristic equivalent replacement.The unaccomplished matter of the utility model belongs to this field skill
The common knowledge of art personnel.
