Description
Technical field
The utility model relates to bolt technical fields, and in particular to one kind can high-altitude right angle setting can bilateral fastening rotating-proof axis
Anti-drop bolt.
Background technique
Currently, most mill constructions are steel structure assembling form, workshop steel structure bolt generally uses outer-hexagonal height
Strength bolt.Workshop steel structure is installed initial stage modes of being ascended a height etc. by building scaffold, paralell being tied up on crane, using spider-man and pacified
Fill bolt.After the workshop steel structure bolt project installation phase.There are following difficulties for workshop steel structure bolt daily maintenance:
1, it shaft phenomenon occurs can not fasten since frictional force reduces in workshop steel structure tightening process for a bolt；
2, workshop steel structure bolt is easy to fall missing, and there are security risks for falling from high altitude.
3, high empty region polishing bolt difficulty is big, is related to high altitude operation, is absolutely unsafe.
The steel structure bolt of the workshop of polishing missing needs to expend a large amount of manpower and material resources.
Utility model content
(1) technical problems to be solved
In order to overcome the shortage of prior art, it is proposed that one kind can high-altitude right angle setting can bilateral fastening rotating-proof axis anti-dropout spiral shell
Bolt facilitates installation to fasten, while preventing from inadvertently falling off.
(2) technical solution
The utility model is achieved through the following technical solutions: the utility model proposes one kind can high-altitude right angle setting can be double
Side fastening rotating-proof axis anti-drop bolt, including bolt body, it is characterised in that: the bolt body includes molding cap head and spiral shell
Column is provided with a hexagon end head in the end of stud, and the maximum outside diameter of the hexagon end head is not more than stud diameter, at hexagonal end
The side of head, which extends through, is provided with hanging wire perforation and a pin hole, is equipped with lanyard, the pin hole in the hanging wire perforation
Inside it is equipped with split pin.
(3) beneficial effect
The utility model compared with the existing technology, has the advantages that
One kind that the utility model is mentioned can high-altitude right angle setting can bilateral fastening rotating-proof axis anti-drop bolt, mainly fit
It is installed for workshop steel structure high-altitude bolt, it is convenient directly to enter bolt lifting in bolt hole, while hexagon end head is convenient
Simultaneously cap is carried out, nut can be quickly installed, split pin can prevent bolt falling from high altitude caused by nut loosening.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
1- cap head；2- stud；3- hexagon end head；The perforation of 4- hanging wire；5- pin hole；6- lanyard；7- split pin.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
One kind as shown in Figure 1 can high-altitude right angle setting can bilateral fastening rotating-proof axis anti-drop bolt, including bolt body,
The bolt body includes molding cap head 1 and stud 2, and the end of stud 2 is provided with a hexagon end head 3, the hexagonal end
First 3 maximum outside diameter is not more than 2 diameter of stud, extends through in the side of hexagon end head 3 and is provided with hanging wire perforation 4 and one
Pin hole 5 is equipped with lanyard 6 in hanging wire perforation 4, is equipped with split pin 7 in the pin hole 5.
One kind that the utility model is mentioned can high-altitude right angle setting can bilateral fastening rotating-proof axis anti-drop bolt, specific
In use, since workshop high-altitude steel structure position is higher lower bolt can be carried out by installing scaffold when early period installs
Installation, once and bolt lacks, scaffold builds trouble and is then difficult to carry out the interspersed of bolt from bottom, and the utility model is in reality
Shi Shi, worker may stand in the top of steel construction, be hung down out of bolt hole by a lifting rope 6 to ground, then by 6 setting fastening of lifting rope
In in lanyard perforation 4, then pull-up lifting rope 6, then can quickly be penetrated stud 2 to bolt hole, while make cap head 1
In the bottom of steel construction, then by and nut tightly be threaded to 2 top of stud, using a spanner turn nut, and utilize another
One spanner clamps hexagon end head 3, and the fastening of nut can be realized, and can prevent that stud 2 occurs while tightening nut
Split pin 7 is inserted into pin hole 5 by shaft phenomenon after tightening nut, and after can preventing nut loosening, bolt body is high
Sky falls and causes phenomenon of hurting sb.'s feelings.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this
Novel conception and scope is defined.Without departing from the design concept of the present utility model, ordinary people in the field couple
The all variations and modifications that the technical solution of the utility model is made, should fall within the protection scope of the present utility model, this reality
With novel claimed technology contents, it is all described in the claims.
