Description
Technical field
The present invention relates to a kind of engineering machinery, and in particular to a kind of dropping-proof hook of crane.
Background technology
Crane, 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, carry whole load of handling, 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 3, including hook body and anti-drop rod, anti-drop rod includes the pivot being oppositely arranged
End and free end, hub switch side is hinged on the upper end of hook body, free end is close to hook body by the compression of hub switch side
On the inwall of bill, prevent lifting rope from breaking off relations.But there is following defect in so anticreep design：Because anti-drop rod is close to hook body
On the inwall of bill, when taking out or changing lifting rope, need artificially to press downwards anti-drop rod towards the inner space of hook body, if
Lifting rope it is heavy, it is necessary to two people operation could complete, waste of manpower；Further, since anti-drop rod takes hook body aperture area, if
Lifting rope size is larger, can be small because of the aperture area between anti-drop rod and hook body bill, and makes lifting rope replacing or the difficulty taken out
Degree increases, and reduces operating efficiency.
The content of the invention
In view of the shortcomings of the prior art, the present invention provides a kind of dropping-proof hook of crane, and this dropping-proof hook sets
The anti-drop rod that can slide up and down is put, is easy to the taking-up and replacing of lifting rope, and it is easy to operate, manpower is saved, while effectively improving work
Make efficiency.
In order to achieve the above object, the technical scheme that the present invention takes：
The dropping-proof hook of crane, including hook body, the upper end of the hook body are provided with an anticreep mounting seat, institute
State and a vertical slideway is offered in anticreep mounting seat, the vertical slideway is provided with the sliding block that can be moved up and down along it, the cunning
Block is provided with is close to anticreep mounting seat side and vertically arranged anti-drop rod, and the anti-drop rod and sliding block are integrally formed and logical
Cross moving handle to be connected with anticreep mounting seat, offering one on the bill inwall of the hook body can be arranged anti-drop rod bottom
Groove, and the shape of the groove matches with the shape of the anti-drop rod bottom.
As optimal technical scheme, in order that anti-drop rod bottom facilitates removal of and enter groove, operating efficiency is improved, while
Ensure that anti-drop rod and groove fit are closely consolidated, anticreep performance is high, and 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 that 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 vertically slideway can be moved up and down by moving handle, conveniently and efficiently realize the opening of hook body
And closing, 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
Make efficiency.
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 fit are closely consolidated, improves the anticreep of suspension hook.
3rd, hook body is made up of 34Cr2Ni2Mo materials, controls the volume of hook body, so that mitigate its deadweight, together
When ensure the enough intensity of hook body, extend its service life.

Specific embodiment
A kind of specific embodiment of the invention, the dropping-proof hook of crane, including suspension hook sheet are proposed as depicted in figs. 1 and 2
Body 1, the upper end of the hook body 1 is provided with an anticreep mounting seat 2, the anticreep mounting seat 2 and offers a vertical slideway 3,
The vertical slideway 3 is provided with the sliding block 4 that can be moved up and down along it, and the sliding block 4 is provided with is close to the one of anticreep mounting seat 2
Side and vertically arranged anti-drop rod 5, the anti-drop rod 5 and sliding block 4 are integrally formed and by moving handle 6 and anticreep mounting seat
1 connection, i.e., by pulling moving handle 6 up or down, moving handle 6 drives anti-drop rod 5 and sliding block 4 to move up and down, described
One is offered on the bill inwall of hook body 1 can be arranged the groove 7 of the bottom of anti-drop rod 5, i.e. the bottom of anti-drop rod 5 is nested in recessed
In groove 7, and the shape of the groove 7 matches with the shape of the bottom of the anti-drop rod 5, the bottom of the groove 7 and anti-drop rod 5
Shape 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 due to groove 7
Design with the lower shape of anti-drop rod 5 can avoid crane from being hung during handling and when loading and unloading article without slipping
Rope breaks off relations, and the security hidden trouble for causing.
The groove 7, the bottom of anti-drop rod 5 are respectively provided with trapezoidal shape, on the one hand make anti-drop rod 5 bottom facilitate removal of and
Into groove 7, operating efficiency is improved, on the other hand ensure that anti-drop rod 5 and groove 7 coordinate closely firm, prevented 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
Light its 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 2, it is necessary to take out or change lifting rope
When, moving handle 6 is pulled downward on, so that moving handle 6 is moved up with movable slider 4 along vertical slideway 3, and then make anti-drop rod
5 depart from groove 7, hook body 1 is in open mode as shown in Figure 1, after taking out or changing lifting rope, pull downward on mobile hand
After handle 6, hook body 1 can be made to recover closed state as shown in Figure 2.
Certainly, the preferred embodiments of the disclosure is described in detail with reference to accompanying drawing simply above, not with this
Practical range of the 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.
