Description
Technical field
The utility model is related to hoisting transportation equipment technical fields, are related specifically to a kind of pulley hook for fixed pulley.
Background technology
Fixed pulley is a kind of common mechanical transmission component.The fixed pulley of crane hoisting mechanism is in arrangement, according to not
With the structure type of crane hoisting mechanism and it is different.
No matter that arrangement form is used, and simplest mode is exactly pulley hook will to be installed on fixed pulley, then by pulley
Hook is hooked in the equipment to be hung (such as line or rack).This mode the fastest can carry out peace installation and dismantling to fixed pulley
It unloads.However still using this arrangement, there is also security risks, since pulley and pulley base itself have certain weight,
Simple be hooked in rack using pulley hook does not take any fixation, and fixed pulley will produce shaking, encounter violent impact
It also occur that the danger broken off relations after power.
Currently in order to anti-locking hook, using installing reversed anti-drop device on the inside of coupler body, but this structure anticreep fills
The space occupied on the inside of coupler body is set, when taking out pulley hook, also anti-drop device is first subjected to rotating opening, needed
A large amount of inner space is reserved in coupler body, is operated very inconvenient.
Therefore it needs to design a kind of new pulley hook.
Invention content
Technical problem to be solved in the utility model is to overcome the deficiencies of existing technologies, and provides a kind of simple in structure, is added
Work is easy, and is not take up coupler body inner space, and there is good anticreep effect, personnel to carry out convenient and efficient when hook taking operation, reduction
Hand labor intensity carries the efficient pulley hook for fixed pulley.
To achieve the goals above, the utility model uses following technical scheme：
A kind of pulley hook for fixed pulley, includes hook seat and coupler body, and the lower end of coupler body is hingedly mounted on hook seat
Upper end, which is characterized in that anti-drop device is also equipped on the inside of the coupler body, anti-drop device is the intermediate plate of an arc,
Intermediate plate using two pieces of arcs iron plate it is opposite install, and remain with cavity in centre, two pieces of iron plates are by the point of coupler body
It is clamped in centre；The point that the intermediate plate is hinged on coupler body is free to rotate, and an end of intermediate plate can be turned to coupler body
It is blocked on inner wall, the opening of coupler body is closed.
In the above scheme, there are two extreme positions when intermediate plate rotation, and the extreme position on the left side is coupler body inner wall
Stopped, the extreme position on the right is to be overlapped with the gib head position of coupler body.
In the above scheme, the hook seat is welded for plurality of steel plates, and the inside of hook seat is cavity, is used in cavity
Fixed pulley is installed, and is provided with horizontal installation axle on hook seat, fixed pulley is arranged on the mounting shaft.
In the above scheme, the size of the opening of the coupler body is less than the diameter in space in coupler body, the tip of coupler body
Portion is that a flat structure carries out being hinged for intermediate plate for trepanning.
The principles of the present invention are for traditional anti-drop device to be transferred to the point of coupler body from the inner wall of coupler body,
The space occupied is needed when reducing anti-drop device rotation, pulley is facilitated to be hooked into row installation and win.
The utility model is by adopting the above-described technical solution, have the advantages that：
The utility model is simple in structure, handling ease, is not take up coupler body inner space, has good anticreep effect, people
It is convenient and efficient when member's progress hook taking operation, hand labor intensity is reduced, efficiency is improved.

Structure chart when Fig. 2 is the utility model embodiment hook taking.
Fig. 3 is the utility model embodiment intermediate plate internal structure chart.
In figure：1- hook seats, 2- coupler bodies, 3- intermediate plates, 4- clamping screws, 5- installation axles.
Specific implementation mode
In order to make the content of the utility model readily apparent be understood, below according to specific embodiment and combine attached
Figure, is described in further detail the utility model.
As shown in Figure 1, Figure 2, Figure 3 shows, it is used for the pulley hook of fixed pulley, includes hook seat 1 and coupler body 2, the lower end of coupler body 2
It is hingedly mounted on the upper end of hook seat 1 { such as：Coupler body 2 is vertically installed at 1 end face of hook seat, and can be pivoted }, the coupler body 2
Inside be also equipped with anti-drop device, anti-drop device is the intermediate plate 3 of an arc, and intermediate plate 3 is opposite using the iron plate of two pieces of arcs
Installation is into (at least two blocks of steel plates are welded, and the upper end of two blocks of steel plates is connected by axis, and axis is rotatable, under two blocks of steel plates
End is connected by bar), and remaining with cavity in centre (part of the point of coupler body 2 can be in cavity, it is possible to increase opening is empty
Between), the point of coupler body 2 is clamped in centre by two pieces of iron plates；The point that the intermediate plate 3 is hinged on coupler body 2 can freely turn
It is dynamic, and an end (left end) for intermediate plate 3 can be turned on 2 inner wall of coupler body and be blocked (as shown in Figure 1), by the opening of coupler body 2
Place's closing.
Several hinge joints are provided on the intermediate plate 3, each hinge joint includes clamping screw 4, by intermediate plate 3
It is locked with the point of coupler body 2.
In the present embodiment, there are two extreme positions when the intermediate plate 3 rotates, and the extreme position on the left side is in coupler body 2
