Abstract
The invention discloses a controllable lifting hook for a crane. The controllable lifting hook mainly comprises a lifting hook component and a pulley component, wherein the lifting hook component comprises a lifting hook seat body and a lifting hook body perpendicularly arranged on the lifting hook seat body through a lifting hook shaft; the pulley component comprises a pulley shaft transversely arranged on the lifting hook seat body; at least two lifting pulleys on which lifting ropes are wound are arranged on the pulley shaft; a motor is arranged on the side of the lifting hook seat body, and is provided with a driving gear through a motor shaft; a driven gear meshed with the driving gear is fixed on the lifting hook shaft; the at least two lifting pulleys on which the lifting ropes are wound are symmetrically arranged on the two end sides of the pulley shaft respectively; pulley shells are symmetrically arranged outside the lifting pulleys; the motor is arranged on one side edge between the two pulley shells; the motor shaft is connected with the driving gear consisting of a gear shaft; the lifting hook shaft is perpendicularly arranged below the middle part of the lifting hook seat body through a plane bearing. The controllable lifting hook has the characteristics of simple structure, safety and reliability in use, capability of reducing the labor intensity of an operator, simplicity in operation, capability of improving the heavy object lifting safety and the like.
Description
Technical field
What the present invention relates to is a kind of controllable type suspension hook of hoisting crane, belongs to hoisting crane technical field.
Background technology
Hoisting crane refers to many actions elevator machinery of vertical-lift within the specific limits and horizontal carrying heavy goods, claims again crane.Belong to material carrying machine.The work characteristics of hoisting crane is to do intermittent exercise, and in a working cycle, the corresponding mechanism of the action such as feeding, migration, unloading is alternation.
At present, the basic system composition of hoisting crane is: in the time of lifting weight, all rely on lifting mechanism to connect the suspension hook with hook assembly and pulley assembly by rope, thereby sling weight, but because the hook in hook assembly is connected on suspension hook pedestal and arbitrarily and is rotated by suspension hook axle, therefore the weight of slinging need to rotate 0-360 degree when arbitrarily angled, existing hoisting crane can only rely on manual operation to realize, moreover, in lifting process, owing to lacking controllable mechanism between hook and suspension hook pedestal, thereby hook can or rock and rotate or rock along with the rotation of weight in moving process, in lifting, in migration and when unloading, are because of the uncontrollable generation that causes potential safety hazard.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and it is improved, simple in structure to provide one to carry out on prior art basis, safe and reliable, can not only reduce operator's labour intensity, and simple to operate, the controllable type suspension hook of the hoisting crane of raising hoisting heavy safety.
The object of the invention is to realize by following technical solution, the controllable type suspension hook of described hoisting crane, it is mainly made up of hook assembly and pulley assembly, and described hook assembly comprises a suspension hook pedestal, and one by the hook of suspension hook axle positioned vertical on suspension hook pedestal; Described pulley assembly comprises that one is horizontally placed on the sheave shaft on suspension hook pedestal, on this sheave shaft, be mounted with at least two lifting pulleys that are surrounded with lifting rope, on the avris of described suspension hook pedestal, a motor is installed, this motor is provided with a driving gear by motor shaft, is fixed with a driven gear engaging with described driving gear on described suspension hook axle.
The both end sides of described sheave shaft respectively symmetrical placement has at least two lifting pulleys that are surrounded with lifting rope, outside is provided with the pulley shell being arranged symmetrically with, described motor is placed on the side between two pulley shells, and motor shaft is connected to a driving gear being made up of gear wheel shaft; Described suspension hook axle is arranged vertically below the centre of suspension hook pedestal by surface bearing.
The present invention is the improvement to prior art, described crane hook body can rotate along with the rotation of suspension hook axle, and suspension hook axle is to be driven by gear drive by motor, and can realize any controllable rotating of 0-360 degree degree, thereby it is simple in structure that the present invention is had, safe and reliable, can not only reduce operator's labour intensity, and simple to operate, improve hoisting heavy safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the side-looking structural representation of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1,2, the controllable type suspension hook of hoisting crane of the present invention, it is mainly made up of hook assembly and pulley assembly, described hook assembly comprises that a suspension hook pedestal 1, is by the hook 3 of suspension hook axle 2 positioned vertical on suspension hook pedestal 1; Described pulley assembly comprises that one is horizontally placed on the sheave shaft 4 on suspension hook pedestal 1, on this sheave shaft 4, be mounted with at least two lifting pulleys 6 that are surrounded with lifting rope 5, one motor 7 is installed on the avris of described suspension hook pedestal 1, this motor 7 is provided with a driving gear 8 by motor shaft, is fixed with a driven gear 9 engaging with described driving gear 8 on described suspension hook axle 2.
Shown in figure, the both end sides of described sheave shaft 4 respectively symmetrical placement has at least two lifting pulleys 6 that are surrounded with lifting rope 5, outside is provided with the pulley shell 10 being arranged symmetrically with, described motor 7 is placed on the side between two pulley shells 10, and motor shaft is connected to a driving gear being made up of gear wheel shaft 8; Described suspension hook axle 2 is arranged vertically below the centre of suspension hook pedestal 1 by surface bearing 11.
The present invention in use, can be by the control of motor, realize the rotation control to crane hook body, and by the control to hook, realize the control of hook position, can realize any controllable rotating of hook 0-360 degree, realize smoothly, safely the actions such as weight lifting, migration, unloading.
