Description
Technical field
The present invention relates to a kind of fastener installation method more particularly to a kind of bolt installation methods of narrow space.
Background technique
Be bolted as it is a kind of it is common be fastenedly connected mode, be suitable for a variety of connection occasions.But in reality,
The much positions that are fastenedly connected often narrow spaces, make us hand and operational instrument all hardly enter, can not carry out directly
The bolt connection connect.
For example, the Chinese invention of existing Publication No. CN102135127A discloses " a kind of bolt and nut component and one
Kind is fastenedly connected method for small space ", wherein bolt and nut component includes connecting plate, and the connecting plate, which is equipped with, to be used
In the connecting hole that nut passes through, the cross-sectional area of the nut bottom is greater than the cross-sectional area on head, and the nipple heads are equipped with
Outside flange, the profile that the flange outer rim is formed are wider than the outer rim of connecting hole, further include and the matched bolt of nut.Together
When, it also discloses and a kind of is fastenedly connected method for small space, comprising the following steps: the first step penetrates nipple heads
Connecting hole on connecting plate, the cross-sectional area of the nut bottom are greater than the cross-sectional area on head；Second step is opened in nipple heads
Outside flange, the profile that the flange outer rim is formed are wider than the outer rim of connecting hole；Connecting plate is protruded into narrow sky by third step
Between, make area of the nipple heads alignment to the connecting hole of connector, or stretch out from the connecting hole to connector；4th step, is helped
Firmly connecting plate outer rim will be fastenedly connected using with the matched bolt of nut to connector.
For another example the Chinese invention of Publication No. CN106545560A discloses " a kind of bolt connection of small space ",
The following steps are included: firstly, being provided with and the fork pockets with the cooperation of U mouthfuls of thin plates in bolt by tight end；Then, nut is first screwed into bolt
In, then by the through-hole of bolt the first connected piece of insertion and the second connected piece, U mouthfuls of thin plates of band is then made to be stuck in bolt root
Fork pockets at, last rotating nuts, to the first connected piece respectively and the second connected piece apply pressure, connection fastening i.e. complete connect
Termination process.
Summary of the invention
The technical problem to be solved by the present invention is to be directed to the status of the prior art, a kind of bolt installation of narrow space is provided
Method realizes that bolt can be extended into the installation of narrow space, especially bolt, not can be carried out installation bolt by hand just
Occasion.
The technical scheme of the invention to solve the technical problem is: a kind of bolt installation method of narrow space,
Characterized by comprising the following steps:
Step S1 pinions the end of thread of one end of tightrope and bolt, and the other end of tightrope and the lower end of steel wire connect；
Step S2, bends steel wire, so that the shape of steel wire and the narrow space of one of connected piece are mutually fitted
Match；
The connecting hole of the connecting hole of one of connected piece and another connected piece is aligned, steel wire by step S3
Upper end sequentially pass through the connecting holes of two connected pieces, hold steel wire upper end, under the effect of gravity, bolt state in a vertical shape will
Tightrope is straightened, and pulls up steel wire, and tightrope hauls bolt across connecting hole；
Washer and nut are successively inserted on bolt, hold tightrope upwards by step S4, by nut tightening；
Step S5 cuts short tightrope, completes connection.
As an improvement, a washer is passed through steel wire, is inserted in bolt in the step S3.
Compared with the prior art, the advantages of the present invention are as follows: the upper end of tightrope and bolt is attached by the present invention first,
Tightrope has flexibility, can convert arbitrary shape according to operating condition, in particular, when for the connecting hole being vertically arranged, in weight
Under power effect, tightrope is straightened bolt naturally, so that bolt is able to maintain vertical state, and it is opposite with connecting hole convenient for bolt；
Meanwhile the steel wire that uses of the present invention also has certain rigidity while have certain flexibility, in this way, in narrow space
In the case of, longer steel wire can easily pass through connecting hole, during bolt is inserted into connecting hole, without hand-held bolt, spiral shell
Bolt can enter in connecting hole along steel wire and tightrope and then tightening nut, easy to operate, meanwhile, realize spiral shell
Installation of the bolt in narrow space.
Detailed description of the invention
Fig. 1 is in the embodiment of the present invention in the mounting structure schematic diagram of narrow space bolt installation；
Fig. 2 is the structural schematic diagram in the embodiment of the present invention after the installation of narrow space bolt.
Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
As illustrated in fig. 1 and 2, the bolt installation method of narrow space of the invention, comprising the following steps:
Step S1 pinions one end of tightrope 2 and the end of thread of bolt 1, and the other end of tightrope 2 and the lower end of steel wire 3 connect
It connects；
Step S2 bends steel wire 3, so that the narrow space 8 of the shape of steel wire 3 and one of connected piece 4
It is adapted；
The connecting hole of the connecting hole of one of connected piece 4 and another connected piece 5 is aligned, steel by step S3
The upper end of silk 3 sequentially passes through the connecting hole of two connected pieces, holds 3 upper end of steel wire, and under the effect of gravity, bolt 1 is in vertical
Tightrope 2 is straightened state, pulls up steel wire 3, and tightrope 2 hauls bolt 1 across connecting hole；
Washer 6 and nut 7 are successively inserted on bolt 1 by step S4, hold tightrope 2 upwards, nut 7 is screwed；
Step S5 cuts short tightrope 2, completes connection.
Further, when the aperture of connecting hole is larger, can a washer be passed through into steel wire 3, be inserted in spiral shell in step s3
On bolt 1, the reliability that bolt 1 connects is improved.
In addition, in step s 4, when narrow installation space can allow for finger to protrude into, can use finger tip for bolt
1 lower part is withstood, in this way, screwing convenient for nut 7.
In addition, in step s 5, the tightrope 2 on bolt 1 can also be blown with lighter, guarantee on bolt 1 not
Remain tightrope 2.
To sum up, tightrope 2 and the upper end of bolt 1 are attached by the present invention first, and tightrope 2 has flexibility, being capable of basis
Operating condition convert arbitrary shape, in particular, for be vertically arranged connecting hole when, under the effect of gravity, bolt 1 by tightrope 2 from
So it is straightened, so that bolt 1 is able to maintain vertical state, and it is opposite with connecting hole convenient for bolt 1；Meanwhile the steel that the present invention uses
Silk 3 also has certain rigidity while having certain flexibility, in this way, in the case where narrow space 8, longer steel wire
3 can easily pass through connecting hole, and during bolt 1 is inserted into connecting hole, without hand-held bolt, bolt 1 can be along steel wire 3
With tightrope 2 enter connecting hole in and then tightening nut 7, it is easy to operate, meanwhile, realize bolt 1 in narrow sky
Between 8 installation.
