Description

It is a kind of for dismantling the sleeve of railroad sleeper nut

Technical field

A kind of sleeve for dismantling railroad sleeper nut is related to small-sized railway maintenance equipment, is especially for dismantling The special equipment of railroad sleeper nut.

Background technique

Currently, it is that rail is fixed on sleeper with fastener that railway, which has tiny fragments of stone, coal, etc. route, fastener is the dedicated spiral shell of railway Bolt nut.Locking or disassembly fastener used in tool be various track wrench, for its power source, have it is motor-driven, There is gasoline engine driven；For its structural shape, there is single head portable, has double end rail-mounted.No matter which kind of bolt is pulled Hand requires that the nut in fastening bolt could be locked by sleeve or unclamp operation.Present railway maintenance construction institute Sleeve is by a set of multiple sleeves with hexagon ring or 12 corner apertures and is equipped with the attachmentes such as handle, extension bar and forms, for covering Enter hex nut.But disassembly nut construction in often occur hex nut because of abrasion, corrode or sleeve cannot be embedded in due to colliding with Situation in recessed hex hole seriously affects railway maintenance work so that a set of multiple sleeves are unsuitable for being inserted in hex nut Industry progress is developed a kind of for dismantling the sleeve of railroad sleeper nut there is an urgent need to innovative design, has tiny fragments of stone, coal, etc. line to adapt to railway Way bed maintenance work there is an urgent need to.

Summary of the invention

The purpose of this utility model be exactly innovation develop it is a kind of for dismantling the sleeve of railroad sleeper nut, to adapt to railway Have tiny fragments of stone, coal, etc. route railway roadbed maintenance work there is an urgent need to.

The technical solution of the utility model is: being made of gripping block, inner sleeve, housing, straight pin, thread bush and door special With sleeve, inner sleeve one end is formed with three holes for clamping for being embedded in gripping block circumferentially divided equally, and the other end, which is formed with, accommodates straight pin Groove；Hollow male cone (strobilus masculinus) is made in housing one end, and clamping slot corresponding with inner sleeve is produced on the conical surface, and the other end is made in left-handed Screw thread is engaged with the thread bush for being formed with sinistral external thread；Thread bush radially produces through-hole, is connected with the inner sleeve by straight pin, The square hole for track wrench insertion is formed in thread bush；Gripping block, each clamping are installed in the holes for clamping that inner sleeve and housing are formed Block two sides are formed with the wedge shape of gradient same as housing male cone (strobilus masculinus), and the axial deep trouth annular knurl for clamping sleeper nut is produced in inside.

It is had the beneficial effects of the utility model are: efficiently solving railway and having in the disassembly nut construction of tiny fragments of stone, coal, etc. route railway roadbed Hex nut because of abrasion, the problem corroding or cannot be embedded in due to colliding in the recessed hex hole of sleeve, greatly speed up railway maintenance Job scheduling, high production efficiency is adaptable, and novel in design, structurally reasonable, operation is comfortably, securely and reliably.

Specific embodiment

The details and the course of work of the utility model are described in detail in conjunction with Fig. 1.By gripping block 1, inner sleeve 2, housing 3, cylinder The socket wrench specially adapted for it that pin 4, thread bush 5 and door 6 form, 2 one end of inner sleeve are formed with three folders for being embedded in gripping block 1 circumferentially divided equally Tieholen, the other end are formed with the groove for accommodating straight pin 4；Hollow male cone (strobilus masculinus) is made in 3 one end of housing, produces on the conical surface and inner sleeve 2 Levogyrate inner thread is made in corresponding clamping slot, the other end, engages with the thread bush 5 for being formed with sinistral external thread；Thread bush 5 is along diameter It to through-hole is produced, is connect by straight pin 4 with inner sleeve 2, the square hole for track wrench insertion is formed in thread bush 5；Inner sleeve 2 and outer Gripping block 1 is installed in the holes for clamping that set 3 is formed, each 1 two sides of gripping block are formed with the wedge shape of gradient same as 3 male cone (strobilus masculinus) of housing, Produce the axial deep trouth annular knurl for clamping sleeper nut in inside.Gripping block 1, inner sleeve 2, housing 3, straight pin 4, thread bush 5 and door 6 It is made of superior alloy steel, and is strictly heat-treated.Door 6 is formed with the left-handed outer spiral shell being meshed with 3 levogyrate inner thread of housing Boss is produced in line, one end, and boss outer rim is formed with for installing, the spanner slot of disassembly.First thread bush 5 is screwed in housing 3, then Inner sleeve 2 is embedded into thread bush 5, is connected with straight pin 4, three gripping blocks 1 are sequentially loaded into inner sleeve 2, are embedded in housing after installing 3, it finally screws in door 6 and tightens, socket wrench specially adapted for it just installs.When railway has tiny fragments of stone, coal, etc. route railway roadbed maintenance work, by this cover special Cylinder imbeds in the track wrench of disassembly railroad sleeper nut, and the hex nut such as having in disassembly nut construction is because wearing, becoming rusty When losing or colliding with and the situation in the recessed hex hole of general sleeve cannot be embedded in, using this socket wrench specially adapted for it can conveniently and efficiently by The hex nut for wearing, corroding or colliding with disassembles.The beneficial effects of the utility model are: efficiently solving railway has tiny fragments of stone, coal, etc. line In the disassembly nut construction of way bed the hex nut that has because of abrasion, corrode or the recessed hex hole of sleeve cannot be embedded in due to colliding with Interior problem greatly speeds up railway maintenance job scheduling, and high production efficiency is adaptable, novel in design, structurally reasonable, operation Comfortably, securely and reliably.
