Abstract
The invention discloses an end part rotating pin mechanism of a moveable dual-cabinet power-driven lifting appliance. The end part rotating pin mechanism comprises a rotating pin, a reducing motor, a transmission shaft, a connecting rod, a first rotating crank and a second rotating crank. The reducing motor is located at an end beam, connected to the transmission shaft and outputs driving force to drive the transmission shaft to rotate; the transmission shaft is connected with the middle part of the connecting rod by the first rotating crank, the two ends of the connecting rod are connected with the two ends of the rotating pin by the second rotating crank and drive the rotating pin to lock or unlock. The Locking/unlocking position is fed back and controlled by induction limit. In the invention, the reducing motor provides driving force for the end part rotating pin mechanism of the moveable dual-cabinet power-driven lifting appliance, controls locking and unlocking motion of the dual-cabinet lifting appliance, solves the defect that the traditional hydraulic dual-cabinet lifting appliance has high failure rate, wastes power, produces loud noise, pollutes the environment and the like and simplifies the structure of the lifting appliance.
Description
Technical field
The present invention relates to the movable double-box electric lifting tool of container handling crane.
Background technology
What the end rotating pin mechanism of traditional movable double-box hanger adopted is that hydraulic ram drives.There are many shortcomings in this technology.At first, because the problems such as leakage of hydraulic efficiency pressure system, in use fault rate is higher to cause double-box hanger; Secondly, the hydraulic ram actuating speed is slow, and noise is bigger; Once more, the problems such as leakage of oil cylinder can cause the feature of environmental protection of suspender relatively poor.Therefore, need badly a kind of fault rate low, can rapidly opened and closedly lock, the end rotating pin mechanism of environmental protection more.
Summary of the invention
The objective of the invention is with the propulsive effort of reducing motor as the end rotating pin mechanism of double-tank movable hanger, the switching lock action of control double-box hanger, solve shortcomings such as the big and contaminated environment of the fault rate height, waste of energy, noise of conventional hydraulic double-box hanger, and simplified hanger structure.
For achieving the above object, the invention provides a kind of movable double-box electric lifting tool end rotating pin mechanism.
In one embodiment, this end rotating pin mechanism comprise end carriage, ship and resell on another market, reducing motor, transmission shaft, connecting rod, first turning handle and second turning handle.Reducing motor is positioned at the end carriage place, is connected to transmission shaft and outputting power and drives the transmission shaft rotation; Transmission shaft connects the connecting rod middle part by first turning handle; The connecting rod two ends are carried out locking or unlocking by second turning handle with shipping and reselling on another market to be connected and to drive to ship and resell on another market.The position of open and close lock is by responding to the spacing controlled reset that comes.
Description of drawings
Fig. 1 is the front view of the end rotating pin mechanism of electronic movable double-box hanger according to an embodiment of the invention; And
Fig. 2 is the birds-eye view of the end rotating pin mechanism of electronic movable double-box hanger according to an embodiment of the invention.
The specific embodiment
In one embodiment, electronic movable double-box of the present invention end rotating pin mechanism comprises: the 1a that ships and resell on another market, the 1b that ships and resell on another market, connecting rod 2a (first connecting rod), connecting rod 2b (second connecting rod), reducing motor 3, turning handle 4 (first turning handle), transmission shaft 5, turning handle 6 (second turning handle), locking are responded to spacing 7a and 8b, are unblanked to respond to spacing 8a and 7b, as shown in Figure 1 and Figure 2.
Described reducing motor is fixed on the middle part of end carriage, and connecting rod is connected with reducing motor by transmission shaft.Ship and resell on another market and be connected with connecting rod by turning handle.
After the guide agency of suspender was finished case, reducing motor 3 outputting powers drove the rotation of transmission shaft 5, and transmission shaft 5 is by the straight-line motion of turning handle 4 drivening rod 2a and 2b, thereby connecting rod 2 drives the block action of ship and resell on another market 1a and 1b by turning handle 6.The position of its locking responds to spacing 7a by locking and 8b feeds back to hoisting crane to control.
When suspender need break away from freight container and ships and resell on another market when being in unlocking condition, reducing motor 3 outputting powers drive the rotation of transmission shaft 5, transmission shaft 5 is by the straight-line motion of turning handle 4 drivening rod 2a and 2b, thereby connecting rod 2 drives the unlocking action of ship and resell on another market 1a and 1b by turning handle 6.Its position of unblanking is responded to limiting device 8a and 7b and is fed back to hoisting crane to control by unblanking.
In sum, the present invention adopts the propulsive effort of reducing motor as the end rotating pin mechanism of double-tank movable hanger, the switching lock action of control double-box hanger has solved shortcomings such as the big and contaminated environment of fault rate height, waste of energy, the noise of conventional hydraulic double-box hanger, and has simplified hanger structure.
Though the present invention describes with reference to current specific embodiment, but those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, under the situation that does not break away from spirit of the present invention, also can make the variation or the replacement of various equivalences, therefore, as long as in connotation scope of the present invention in the scope to the variation of the foregoing description, claims that modification all will drop on the application.
