Description
Technical field
The utility model is related to constructing tunnel engineering machinery, and in particular to a kind of boom hoisting.
Background technology
It is needed in water power tunnel, subway engineering, railway tunnel, vcehicular tunnel, underground power house, military ground engineering construction
First pneumatically placed concrete.If country rock shakiness rule needs to set up steel arch in advance（Grille arch）, be welded and fixed reinforced mesh etc., be used for frame
If the profile steel frame and reinforced mesh of steel arch concentrated processing, site machinery cooperation outside construction hole are manually installed.Space in tunnel
Narrow large size lifting appliance is put to good use not open, and also needs to manually carry profile steel frame and reinforced mesh substantially.
Utility model content
The purpose of this utility model is to provide a kind of small and exquisite, flexible movements, reliable boom hoistings.
In order to achieve the above object, the technical solution adopted in the utility model is：A kind of boom hoisting, including a bearing, it is described
One end of bearing is hinged one end of first connecting rod, and the other end of the bearing is hinged one end of second connecting rod, the first and second connecting rod
The other end is hingedly connected at two on length of boom direction, so that bearing, first connecting rod, second connecting rod, arm is formed one or four and is connected
Linkage, on two diagonal hinge joints of the four-bar mechanism connection the first and second connecting rod can be made to rotate clockwise or counterclockwise in turn
The drive cylinder of lifting or recycling arm.
Hoist engine is installed in the rear end of the arm, and arm rear end is fixed in the front end installing pulley of arm and suspension hook, one end
Steel wire rope extend along arm and the winding drum through hoist engine is fixed on hoist engine after bypassing pulley, so that the utility model is passed through
The effect of hoist engine and have crane capacity.
The length of the first connecting rod is more than the length of second connecting rod.Alternatively, the length of the first connecting rod is equal to second
The length of connecting rod.
The hoist engine is driven by hydraulic-driven or motor.
The bearing is fixed on slewing equipment so that the utility model can be expanded around the center steering of slewing equipment
The working range of the utility model.
The drive cylinder can also be substituted with electric pushrod.
The hinged a set of double leval jib machine of composition of the utility model bearing, first connecting rod, second connecting rod, arm head and the tail
Two diagonal hinge joints of structure, four-bar mechanism connect drive cylinder, pass through the effect for being telescoped up to arm and taking down the exhibits of drive cylinder.
The relatively traditional crane of the utility model eliminates telescopic arm, has saved and has installed and used space, thus whole small and exquisite, flexible movements,
Reliable operation.
The utility model can be connect by being realized in floor design mounting plate with other bottom surface equipment, realize shaped steel steel
The lifting work of the smallclothes such as frame, reinforced mesh.
Description of the drawings
Fig. 1 is the assembly structure figure of one example of the utility model.
Fig. 2 is the unfolding state figure of one example of the utility model.
Fig. 3 is the utility model four-bar mechanism schematic diagram.
Fig. 4 is the axonometric drawing of one example of the utility model.
Specific implementation mode
As Figure 1-Figure 4, one embodiment of the utility model boom hoisting includes a branch being fixed on slewing equipment 1
Seat 2, one end of the bearing 2 are hinged one end of first connecting rod 3, and the other end of bearing 2 is hinged one end of second connecting rod 4, and first and second
The other end of connecting rod 3,4 is hingedly connected at two in 5 axial direction side of arm, makes bearing 2, first connecting rod 3, second connecting rod 4, arm
5 form a four-bar mechanism.Two diagonal hinge joints of the four-bar mechanism connect drive cylinder 6.Install elevator in the rear end of arm 5
Machine 7, the front end installing pulley 8 and suspension hook 10 of arm 5, the steel wire rope 9 that 5 rear end of arm is fixed in one end extend along arm 5 and around
The winding drum through hoist engine 7 is fixed on hoist engine 7 after crossing pulley 8.
When drive cylinder 6 is stretched out, first connecting rod 3, second connecting rod 4 rotate clockwise the hinge joint on bearing 2, simultaneously
It is lifted with the hinged arm 5 of first connecting rod 3,4 other end of second connecting rod.When first connecting rod 3,4 equal length of second connecting rod
The horizontal attitude of arm 5 will not change, arm 5 and level when the length of first connecting rod 3 is more than the length of second connecting rod 4
Face will there are one angles, suspension hook 10 further to raise.
When drive cylinder 6 is retracted, first connecting rod 3, second connecting rod 4 rotate the hinge joint on bearing 2 counterclockwise, simultaneously
Decline with the hinged arm 5 of first connecting rod 3,4 other end of second connecting rod, the retraction of drive cylinder 6 in place when, that is, complete arm
5 recycling.
The stroke of drive cylinder 6 and the amount of spin of slewing equipment 1 are adjusted, is opened after so that suspension hook 10 is in suitable position
Dynamic hoist engine 7 drives steel wire rope movement that lifting action can be completed.
Wherein drive cylinder 6 can also be substituted with electric pushrod.Hoist engine can be hydraulic-driven, can also be that motor drives
It is dynamic.
