Abstract
It is a kind of to be provided with more suspension centre hoisting systems with self-locking pulley, include the running block of steel wire rope, fixed pulley group and matched effect, fixed pulley group is fixedly connected with steel wire rope, and the fixed pulley group is provided with self-locking device.Compared with prior art, the utility model will set self-locking device in fixed pulley group, one or more groups of fixed pulley synchronous axial systems are realized by the action of self-locking device, so as to which the suspension centre controlled this group of fixed pulley is locked automatically, to realize when a set of hoisting system controls multiple suspension centre liftings, can the suspension centre number that is controlled of free switching this set lifting mechanism, increase the flexibility of crane gear and improve the efficiency of lifting appliance.
Description
Technical field
The utility model belongs to technical field of crane equipment, and in particular to a kind of to be provided with more suspension centre raisings with self-locking pulley
System.
Background technology
Some big, heavy lifts often because hung object size limits, need multiple spot while lifted by crane, again both at home and abroad at present
Because being related to suspension centre synchronization and Cost Problems, a set of hoisting system need to be paid the utmost attention to and control multiple suspension centres.But it is arranged so as to, but limits
The flexibility of lifting appliance, it is impossible to unrestricted choice suspension centre quantity, influence operating efficiency, cause the wasting of resources.
Utility model content
The purpose of this utility model is that task of the present utility model is that proposition is a kind of provided with more suspension centres with self-locking pulley
The system of liter, to realize when a set of hoisting system controls multiple suspension centres to lift by crane, can free switching this set lifting mechanism controlled
Suspension centre number, increase the flexibility of crane gear and improve the efficiency of lifting appliance.
The technical solution of the utility model is specially：
It is a kind of to be provided with more suspension centre hoisting systems with self-locking pulley, including steel wire rope, fixed pulley group and matched effect
Running block, fixed pulley group is fixedly connected with steel wire rope, and the outer of the pulley sheet of the fixed pulley group is matches somebody with somebody with self-locking device
The gear-like of cooperation, the self-locking device include drive device, gear stand, gear train, pulley shield, wherein, the gear
Support one end is hinged with drive device, and the other end is connected with pulley shield, and the gear stand is provided with gear train, the gear train
Number of gears it is equal with the pulley sheet number of fixed pulley group.
The drive device is hydraulic cylinder.
The gear stand is connected by hinge with pulley shield.
The pulley is covered with two.
Compared with prior art, the utility model will set self-locking device in fixed pulley group, and pulley sheet outer is set as
Gear-like is matched, drives gear stand by drive device, gear train is moved to the cunning of correct position and fixed pulley group
Piece engagement is taken turns, so as to realize one or more groups of fixed pulley synchronous axial systems, so as to which the suspension centre controlled this group of fixed pulley is carried out certainly
Dynamic locking, to realize when a set of hoisting system controls multiple suspension centres to lift by crane, can free switching this set lifting mechanism controlled
Suspension centre number, increase the flexibility of crane gear and improve the efficiency of lifting appliance.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram.
Fig. 2 is fixed pulley group schematic diagram.
Fig. 3 is fixed pulley group A-A faces profile.
Embodiment
As Figure 1-3, it is a kind of to be provided with more suspension centre hoisting systems with self-locking pulley, including steel wire rope 1, fixed pulley group 2
With the running block 3 of matched effect, fixed pulley group 2 is fixedly connected with steel wire rope 1, the pulley sheet 9 of the fixed pulley group 2
Outer is gear-like with self-locking device mating reaction, the self-locking device include drive device 4, gear stand 5, gear train 6,
Pulley shield 7, wherein, described one end of gear stand 5 is be hinged with drive device 4, and the other end is connected with pulley shield 7, the gear branch
Frame 5 is provided with gear train 6, and 9 numbers of the number of gears of the gear train 6 and the pulley sheet of fixed pulley group 2 are equal.
During corresponding suspension centre work, thus the same province of multiple suspension centres of steel wire rope control lifts by crane, speed is identical simultaneously with dropping；Phase
When answering the suspension centre not need work, because drive device 4 and gear stand 5 are be hinged, gear stand 5 is in the presence of drive device 4
Rotate, so that gear train 6 rotates relative to pulley sheet 9, reach suitable position, the gear on gear train 6 with
The outer of pulley sheet 9 engagement of fixed pulley group 2 so that pulley sheet 9 in whole fixed pulley group 2 gear train 6 drive similarly hereinafter
Step rotates, and now, fixed pulley group 2 and the matched geo-stationary of running block 3, realizes the automatic locking of the suspension centre.Other
Suspension centre is freely lifted, and speed accordingly increases.
Drive device 4 described in the utility model is hydraulic cylinder, simple in construction, reliable operation, stable movement, operating personnel
It is easily mastered.
Gear stand 5 described in the utility model is connected by hinge 8 with pulley shield 7, simple and convenient, easily dismounting, just
In maintenance.
Pulley shield 7 described in the utility model has two, is arranged on assembly pulley both sides, and assembly pulley is effectively protected
Shield.
