Description

A kind of tower crane lift hook
Technical field
This utility model relates to derrick crane technical field, particularly relates to a kind of tower crane lift hook.
Background technology
Derrick crane is called for short tower crane, also known as tower crane, originates from West Europe.Swing arm is contained in the rotation lifting on towering tower body top Machine.Working space is big, is mainly used in vertically and horizontally conveying and the installation of building element of material in housing construction.By gold Belong to structure, operating mechanism and electrical system three part composition.Metal structure includes tower body, swing arm and base etc..Operating mechanism has Hoist, luffing, four parts of turning round and walk.Electrical system includes motor, controller, power distribution cabinet, connection line, signal and photograph Bright device etc..
In prior art, it is attached by a pulley between suspension hook and rope that derrick crane is used, this Plant device not only poor stability, and in use, the when that suspension hook being suspended in the air, be easy to produce the phenomenon of vibration.
Utility model content
In view of this, it is necessary to a kind of tower crane lift hook improving stability is provided.
This utility model is achieved in that a kind of tower crane lift hook, including two installation steel plates being parallel to each other, Two pulleys and a suspension hook, be connected with each other by multiple bolts between the installation steel plate that said two is parallel to each other, two cunnings Wheel is all located between the installation steel plate that said two is parallel to each other, and two pulleys are in same level position, the middle part of pulley Being in position, axis and be provided with rotating shaft, described pulley is arranged on two by described axis of rotation and installs between steel plates, described in hang Hook is located between two installation steel plates being parallel to each other, and the horizontal level of suspension hook is under the horizontal level of two pulleys Side, and the vertical position of suspension hook is in the middle of vertical position of two pulleys, described suspension hook upper end is provided with the second rotating shaft, institute State suspension hook to be arranged between said two installation steel plate by described second axis of rotation.
Further, the shape of described steel plate is heart.
Further, the extension of described pulley is provided with chute.
The advantage of a kind of tower crane lift hook that this utility model provides is: this utility model is simple and reasonable, By arranging two pulleys and a suspension hook, in use, directly rope is hung over simultaneously on two pulleys, rope and each cunning The contact surface of wheel only has 1/4th of pulley circumference, and contact surface is little, reduces resistance, and arranges two pulleys, increases rope Spacing after bending, prevents when hanging weight, the generation of the easily broken phenomenon of rope, and improves stability, is not likely to produce and quivers The phenomenon trembled occurs, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of tower crane lift hook of this utility model;
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain This utility model, is not used to limit this utility model.
Seeing also Fig. 1 and Fig. 2, wherein Fig. 1 is the structural representation of a kind of tower crane lift hook of this utility model; Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Described a kind of tower crane lift hook, including 10, two pulleys 20 of two installation steel plates being parallel to each other and one Suspension hook 30, is connected with each other by multiple bolts between the installation steel plate 10 that said two is parallel to each other, and two pulleys 20 are all located at Between the installation steel plate 10 that said two is parallel to each other, and two pulleys 20 are in same level position, the center of pulley 20 Be provided with rotating shaft 21 in position, axis, described pulley 20 is rotatably installed in two by described rotating shaft 21 and installs between steel plate 10, Described suspension hook 30 is located between two installation steel plates 10 being parallel to each other, and the horizontal level of suspension hook 30 is in two pulleys 20 The lower section of horizontal level, and the vertical position of suspension hook 30 is in the middle of vertical position of two pulleys 20, described suspension hook 30 Upper end is provided with the second rotating shaft 31, described suspension hook 30 by described second rotating shaft 31 be rotatably installed in said two install steel plate 10 it Between.
The shape of described steel plate 10 is heart, it is simple to be symmetrically installed two pulleys 20.
The extension of described pulley 20 is provided with chute 22, it is simple to be suspended on rope.
This utility model is simple and reasonable, by arranging two pulleys and a suspension hook, in use, directly by rope Hanging on two pulleys, rope only has 1/4th of pulley circumference with the contact surface of each pulley, and contact surface is little simultaneously, reduces Resistance, and two pulleys are set, increase the spacing after rope bending, prevent when hanging weight, sending out of the easily broken phenomenon of rope Raw, and improve stability, it is not likely to produce the phenomenon trembled and occurs, safe and reliable.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model Protection domain within.
