Abstract
A kind of crane automatic decoupling device, including suspension hook and electric drive hydraulic thruster, one end of the telescopic rod end articulated connection plate II of electric drive hydraulic thruster, the other end and suspension hook of connecting plate II are hinged, suspension hook axis is provided at the top of the suspension hook, suspension hook is hinged by suspension hook axis and rack.The rack is pulley fork grillage, and the other end of one end of the right side fixed connecting plate I of pulley fork grillage, connecting plate I is fixed on the push rod pedestal of electric drive hydraulic thruster, and the motor of electric drive hydraulic thruster is arranged above push rod pedestal.The tripping gear of the utility model passes through the flexible of electric pushrod, to realize that the automatic of suspension hook hooks up function, with it is traditional suspension hook gib head is sleeved on by the hole for hoist or hawser of hoisting heavy by crane operator in come compared with realizing hoisting heavy, human cost is saved, automation is realized, processing safety is improved.
Description
Technical field
The utility model is related to crane hook devices, and in particular to a kind of crane automatic decoupling device.
Background technology
Hook gear is that a kind of load-engaging device most widely used on crane usually relies on suspension hook manually when in use
Gib head is sleeved in hole for hoist or hawser by hoisting heavy, to realize that the purpose of hoisting heavy, this kind of method safety performance are poor.
With the development of society, certain require crane hook that can realize automatic unhooking function using unit, enable suspension hook to reach
Automatically weight is hooked up, and weight is moved to the purpose of appointed place.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of crane automatic decoupling device, automatically-unhooked, saving is realized
Human cost improves processing safety.
The technical solution of the utility model is specially：
A kind of crane automatic decoupling device, including suspension hook and electric drive hydraulic thruster, the telescopic rod end of electric drive hydraulic thruster
The other end of one end of end articulated connection plate II, connecting plate II is hinged with suspension hook, and suspension hook axis, suspension hook are provided at the top of the suspension hook
It is hinged by suspension hook axis and rack.
The rack be pulley fork grillage, one end of the right side fixed connecting plate I of pulley fork grillage, connecting plate I it is another
End is fixed on the push rod pedestal of electric drive hydraulic thruster, and the motor of electric drive hydraulic thruster is arranged above push rod pedestal.
It is provided with stroke switchgear by the telescopic rod of the electric drive hydraulic thruster.
The connecting plate II is set to the top of maximum gauge at suspension hook crotch with the hinged position of suspension hook.
Pulley fork grillage is bolted to connection one end of plate I, and the other end of connecting plate I is bolted on push rod
On pedestal.
The top of the pulley fork grillage is provided with pulley, and suspension hook is connect by pulley with crane.
The tripping gear of the utility model is by the flexible of electric pushrod, to realize that the automatic of suspension hook hooks up function, with biography
Being sleeved on suspension hook gib head by crane operator of system realizes hoisting heavy phase in hole for hoist or hawser by hoisting heavy
Than having saved human cost, having realized automation, improve processing safety.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
A kind of crane automatic decoupling device, including suspension hook 2 and electric drive hydraulic thruster 1,2 top of suspension hook are provided with suspension hook axis
4, suspension hook 2 is connect by suspension hook axis 4 with pulley fork grillage 3, and the top of pulley fork grillage 3 is provided with pulley, and suspension hook 2 passes through pulley
It is connect with crane, the right side of pulley fork grillage 3 is bolted one end of connecting plate I 5, and the other end of connecting plate I 5 is logical
It crosses bolt to be fixed on the push rod pedestal 8 of electric drive hydraulic thruster 1, the telescopic rod end of electric drive hydraulic thruster 1 passes through connecting plate II 6
It is connect with suspension hook 1, II 6 both ends of connecting plate are hinged with suspension hook 2 and telescopic rod respectively, and connecting plate II 6 and the connection position of suspension hook 2 install
The top of maximum gauge at 2 crotch of suspension hook, 1 top of push rod pedestal are provided with motor 8, and motor 8 provides the power of suspension hook movement,
It is provided with stroke switchgear 7 by 1 telescopic rod of electric drive hydraulic thruster.
Travel switch, is one kind of position switch, and travel switch makes its contact action be connect to realize using the collision of suspension hook 2
Logical or disjunction control circuit achievees the purpose that the position or the stroke that limit suspension hook 2, in use, after 1 push rod of electric hydaulic is powered,
Push rod is shunk, and by the stroke switchgear 7 on electric pushrod 1, control push rod is shunk, and suspension hook 2 is revolved around suspension hook axis 4
Oblique upper movement is turned to, after moving to the position of the restriction of stroke switchgear 7,2 stop motion of suspension hook；Motor 9 inverts, electronic
Hydraulic push rod 1 pushes suspension hook 2 oliquely downward to move, after suspension hook 2 hooks up weight, 2 stop motion of suspension hook, by adjusting lifting
The position of machine realizes that suspension hook 2 hooks up weight automatically.
Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art
For, under the premise of not departing from the utility model general idea, several changes and improvements can also be made, these should also be considered as
The scope of protection of the utility model.
