Description
Technical field
The utility model relates to crane technical field more particularly to a kind of guiding dresses for reducing hoist rope drift angle
It sets.
Background technique
In the design of lifting equipment, how to increase the service life of load cable is an important problem.
For the cable crane of hydraulic and hydroelectric engineering casting concrete, working level reaches A7 or more, i.e., normal handling rated load
And work is very frequent, and rope speed is quickly, therefore the burden of its load cable is very heavy.When wirerope enters rope race, partially
Angle from rope groove center line, becomes drift angle.Even if the size of drift angle also will affect steel within the scope of the allowable value that specification is fixed
The fatigue life of cord, drift angle is bigger, and fatigue life is shorter.Therefore, the drift angle for reducing hoist rope will extend wirerope
Service life.
Summary of the invention
The utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of guiding dress for reducing hoist rope drift angle
It sets, can reduce drift angle when hoist rope uses by pulley, extend the service life of wirerope.
In order to achieve the above object, the utility model adopts the following technical solutions:
A kind of guiding device reducing hoist rope drift angle, including mounting plate, the two sides of the mounting plate offer peace
Hole is filled, is fixed with two parallel support plates on the mounting plate, the two sides up and down of support plate exceed mounting plate, two branch
It is set between fagging there are two shaft, on the supporting plate, two shafts are located at support plate and exceed for the both ends rotational installation of shaft
The two sides up and down of mounting plate, fixed in the shaft to be equipped with pulley assembly, the pulley assembly includes pulley, spring leaf and solid
Fixed board, spring leaf are total to there are two and are located at the two sides of pulley, and fixed plate is total to there are two and is located at the outside of spring leaf,
The upper and lower ends of spring leaf and fixed plate exceed the outside of pulley, several compression bullets are equipped between spring leaf and fixed plate
Spring, is equipped with tension spring between two spring leafs, the tension spring altogether there are two and be located at the two sides up and down of pulley.
Lightening hole is also provided on the mounting plate.
The side of the pulley is equipped with rope groove.
The beneficial effects of the utility model are: the utility model is provided with two pulleys on guiding device, steel can be made
The outside of the linear motion that cord is linked to be in two pulleys, pulley is provided with spring leaf and fixed plate, in the rotation of pulley
When drift angle occurs in wirerope in journey, the pulling force of tension spring can tighten the spacing between two spring leafs, while compressed spring can also give
One reversed active force of spring leaf extends the service life of wirerope to reduce the drift angle of wirerope.
Detailed description of the invention

It is described in detail below with reference to the embodiments of the present invention referring to attached drawing.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown in Figure 1 to Figure 2, a kind of guiding device reducing hoist rope drift angle, including mounting plate 1, the installation
The two sides of plate 1 offer mounting hole 2, are fixed with two parallel support plates 4 on the mounting plate 1, and up and down the two of support plate 4
Side exceeds mounting plate 1, is set between two support plates 4 there are two shaft 10, the both ends of shaft 10 are rotatably installed in support plate 4
On, two shafts 10 are located at the two sides up and down that support plate 4 exceeds mounting plate 1, and fixation is equipped with pulley in the shaft 10
Component 5, the pulley assembly 5 include pulley 11, spring leaf 7 and fixed plate 8, and spring leaf 7 is total to there are two and is located at pulley
11 two sides, fixed plate 8 altogether there are two and be located at the outside of spring leaf 7, the upper and lower ends of spring leaf 7 and fixed plate 8 are equal
Outside beyond pulley 11 is equipped with several compressed springs 9, is equipped between two spring leafs 7 between spring leaf 7 and fixed plate 8
Tension spring 6, the tension spring 6 are total to there are two and are located at the two sides up and down of pulley 11.
Lightening hole 3 is also provided on the mounting plate 1.
The side of the pulley 11 is equipped with rope groove 12.
The utility model is provided with two pulleys 11 on guiding device, and wirerope 13 can be made to be linked to be in two pulleys 11
Linear motion, the outside of pulley 11 is provided with spring leaf 7 and fixed plate 8, the wirerope 13 in the rotation process of pulley 11
When there is drift angle, the pulling force of tension spring 6 can tighten the spacing between two spring leafs 7, while compressed spring 9 can also give spring leaf 7
One reversed active force extends the service life of wirerope 13 to reduce the drift angle of wirerope 13.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, if the method concept of the utility model and the various improvement of technical solution progress are used, or without
Improvement directly applies to other occasions, both is within the protection scope of the present invention.
