Description
Technical field
The present invention relates to a kind of engineering machinery, and in particular to a kind of safety hook based on bolt.
Background technology
Crane is also known as crane, refers to many action cranes of vertical-lift within the specific limits and horizontal carrying heavy goods
Tool.The work characteristics of crane is to do intermittent exercise, i.e., the phase of the action such as feeding, migration, unloading in a working cycles
It is alternation to answer mechanism, is widely used in the industries such as industrial production, construction industry, cargo berth, storage, is mainly used to
Lift by crane various goods.On crane in addition to power set, elevator steel cable, also suspension hook, and suspension hook is the important set of crane
Into part, important role is play in whole lifting process, whole load of handling are carry, its direct shadow of security
The operation of crane is rung, in use, suspension hook is using process once breaking off relations, damaging, being broken and will cause a serious accident
In want running check suspension hook to whether there is to have potential safety hazard.
Existing suspension hook is mostly as shown in figure 5, hook neck including hook body, located at hook body upper end and located at suspension hook
Anti-drop rod on body, anti-drop rod includes the hub switch side and free end being oppositely arranged, and hub switch side is hinged on the upper end of hook body,
Free end is close on the inwall of hook body bill by the compression of hub switch side, prevent that lifting rope from breaking off relations.But so anticreep is set
There is following defect in meter：On the inwall that hook body bill is close to due to anti-drop rod, when taking out or changing lifting rope, need artificial
The inner space of anti-drop rod towards hook body is pressed downwards, if lifting rope it is heavy, it is necessary to two people operation could complete, waste people
Power；Further, since anti-drop rod takes hook body aperture area, can be because of anti-drop rod and hook body hook if lifting rope size is larger
Aperture area between point is small, and the difficulty increase for making lifting rope change or take out, and reduces operating efficiency.
The content of the invention
In view of the shortcomings of the prior art, the present invention is provided on a kind of safety hook based on bolt, safety suspension hook
The anti-drop rod that its two ends is bolted in hook body is provided with, is easy to the taking-up and replacing of lifting rope, and it is easy to operate,
Manpower is saved, while effectively improving operating efficiency, security performance is high.
In order to achieve the above object, the technical scheme that the present invention takes：
It is arranged on safety hook based on bolt, including hook body, the hook neck located at hook body upper end, the hook neck
There is rotary sleeve can rotate about and cylindrical, the both sides of the rotary sleeve, which are equipped with contiguous block, two contiguous blocks, opens
Provided with a bolt mounting holes, and a contiguous block is provided with the anti-drop connector being connected with it, the anti-drop connector side
The vertically arranged anti-drop rod of connection, the anti-drop rod is integrally formed and by rotary handle and the rotation with anti-drop connector
Set connection, the bottom of the anti-drop rod can be nested into the groove that hook body bill is opened up, and shape and the institute of the groove
The shape for stating anti-drop rod bottom matches, and is connected between the bill of the anti-drop rod and the hook body by wing bolt.
As optimal technical scheme, in order that anti-drop rod bottom facilitates removal of and entered groove, operating efficiency is improved, simultaneously
Ensure that anti-drop rod and groove coordinate close firm, improve anticreep, the groove, the bottom of anti-drop rod are respectively provided with trapezoidal shape.
As optimal technical scheme, in order to control the volume of hook body, so as to mitigate its deadweight, while ensureing suspension hook sheet
The enough intensity of body, extends its service life, and the hook body is made up of 34Cr2Ni2Mo materials.
Compared with prior art, the device have the advantages that：
1st, anti-drop rod two ends are secured by bolts in hook body, conveniently and efficiently realize the opening and envelope of hook body
Close, it is easy to operate, change the defect of many people's operations of existing need and operating difficulties, while saving manpower, effectively improve work effect
Rate, and security performance is high.
2nd, groove, the bottom of anti-drop rod are respectively provided with trapezoidal shape, the bottom of anti-drop rod is facilitated removal of and is entered
Groove, further improves operating efficiency, while ensureing that anti-drop rod and groove coordinate close firm, improves the anticreep of suspension hook.
3rd, hook body is made up of 34Cr2Ni2Mo materials, controls the volume of hook body, so as to mitigate its deadweight, together
When ensure the enough intensity of hook body, extend its service life.

Embodiment
Propose a kind of specific embodiment of the invention as shown in Figure 1, the safety hook based on bolt, including hook body 1, set
Rotary sleeve 3 can rotate about and cylindrical is arranged with hook neck 2 in the upper end of hook body 1, the hook neck 2, it is described
The both sides of rotary sleeve 3 are equipped with contiguous block 4, two contiguous blocks 4 and offer a bolt mounting holes 5, as shown in Figure 3 and Figure 4, and
The contiguous block 4 for being located at side with the bill of hook body 1 is provided with the anti-drop connector 6 being connected with it, i.e., described anticreep
Have on connector 6 and also offer bolt mounting holes 5, the side of anti-drop connector 6 connects vertically arranged anti-drop rod 7, described
Anti-drop rod 7 is integrally formed with anti-drop connector 6 and is connected by rotary handle 8 with the rotary sleeve 3, as shown in Fig. 2 i.e. logical
Overwinding turns rotary handle 8 set is rotated 3 to rotate around hook neck 2, and the bottom of the anti-drop rod 7 can be nested into the bill of hook body 1
In the groove 9 opened up, and the shape of the groove 9 and the shape of the bottom of anti-drop rod 7 match, the groove 9 and anticreep
The lower shape of bar 7 can be designed according to actual conditions, it is ensured that even if the lifting rope in hanging items of hook body 1 has swing, also can
Because the design of groove 9 and the lower shape of anti-drop rod 7 is without slipping, it can avoid crane during handling and load and unload
Lifting rope breaks off relations during article, and passes through between the security hidden trouble caused, the bill of the anti-drop rod 7 and the hook body 1
Wing bolt 10 is connected.
The groove 9, the bottom of anti-drop rod 7 are respectively provided with trapezoidal shape, on the one hand make anti-drop rod 7 bottom facilitate removal of and
Into groove 9, operating efficiency is improved, on the other hand ensures that anti-drop rod 7 and groove 9 coordinate close firm, prevents in hook body 1
Lifting rope break off relations, improve security performance.
The hook body 1 is made up of 34Cr2Ni2Mo materials, and the characteristic of 34Cr2Ni2Mo structural steel is that have high strong
The stability of degree, toughness and good quenching degree and anti-overheat, on the one hand effectively reduces the volume of hook body 1, so as to subtract
Its light deadweight, on the other hand ensures that hook body 1 has enough intensity, so as to extend its service life.
When the present invention is used：When hook body 1 is in closed state as shown in Figure 1, it is necessary to take out or change lifting rope
When, first unclamp wing bolt 10, be rotated further by rotary handle 8, set is rotated and 3 is rotated around hook neck 2, make the bottom of anti-drop rod 7 to
It is preceding or be moved rearwardly out in groove 9, so that hook body 1 is in open mode, takes out or change after lifting rope, rotated with above rotating
Handle 8 it is in opposite direction, be rotated further by rotary handle 8, then set 3 be rotated rotating around hook neck 2, make the bottom of anti-drop rod 7 backward
Or move forward into groove 9, hook body 1 is recovered closed state as shown in Figure 1.
Certainly, simply the preferred embodiments of the disclosure is described in detail with reference to accompanying drawing above, not with this
The practical range of the present invention is limited, the equivalence changes that all principles under this invention, construction and structure are made all should be covered by this
In the protection domain of invention.
