Description

An automatic anchoring device for the pitching mechanism of a quay crane

technical field

The present invention relates to an anchoring device for the pitching mechanism of a quay crane, and more particularly, to an automatic anchoring device for the pitching mechanism of a quay crane.

Background technique

At present, there are mainly two methods for the pitching and anchoring mechanism of the quay crane:

1) The manual manual bolt anchoring method requires the operator to climb to the top of the ladder frame to operate manually, but this method is labor-intensive and cannot be automated.

2) The anchoring method of the lifting hook motor, as shown in Figure 1:

Hook feeding: After the program feeds the hook feeding action signal, the tilting beam lock head 20 moves forward to trigger the hook area limit deceleration switch 21, the motor push rod 22 moves to lift the hook body 25, and when it lifts to a certain angle, the lifting hook is triggered Limit switch 23, the lifting stops. At this time, the tilting beam lock 20 continues to move forward. When the end limit switch 24 of the hook area is triggered, the tilting beam lock 20 stops moving, and the motor push rod 22 moves to make the hook body 25 fall, so that the hook 25 hooks the pitch The girder lock head 20 prevents it from sliding down, and the hooking action is completed at this time.

Hook out: When the program gives the hook action signal, the motor push rod 22 moves the hook body 25 to lift. When the lift reaches a certain angle, the lift hook limit switch 23 is triggered, and the lift stops. Then the tilting beam lock head 20 moves backward, when the signal of the limit deceleration switch 21 in the hook area is restored, the motor push rod 22 moves to make the hook body 25 drop, and the hook out operation is completed at this time.

Detailed ways

The technical solutions of the present invention are further described below with reference to the accompanying drawings and embodiments.

Referring to Figures 1 to 4, the present invention provides an automatic anchoring device for the pitching mechanism of a quay crane, which cooperates with the pitching girder lock 1 and includes a fixed base 2, and the fixed base 2 is connected with a mounting Panel 3, the installation panel 3 is L-shaped, the long arm end 301 of the installation panel 3 is horizontally arranged, and the short arm end 302 of the installation panel 3 is vertically downward connected to the upper surface of the fixing base 2 and fixed.

A through hole 4 is opened on the end 301 of the long arm, and a vertically arranged floating pin 5 is installed in the through hole 4 , and the floating pin 5 is movably connected in the through hole 4 through the fixed pin 6 .

A vertical waist-shaped through hole 501 is formed on the floating pin 5 , and the fixed pin 6 is inserted into the waist-shaped through hole 501 , so that the floating pin 5 can move up and down around the fixed pin 6 .

An electric push rod 9 is installed on the side of the upper surface of the long arm end 301 away from the short arm end 302 through the electric push rod base 8 .

The rear end of the floating arm 10 is provided with two connection holes 1001 arranged up and down. The upper connection hole 1001 is connected with the movable rod on the electric push rod 9 through the first fixed pin 11 , and the lower connection hole 1001 is connected with the second connection hole 1001 . The fixing pin 12 is connected with the ear plate 13 , and the ear plate 13 is fixed on the upper surface of the long arm end 301 .

The front end of the floating arm 10 is provided with a waist-shaped arc-shaped through hole 1002 , and the waist-shaped arc-shaped through hole 1002 is connected to the upper end of the floating pin 5 through the bolt fixing pin 14 .

The lower end of the floating pin 5 is set as a wedge surface towards the direction of the pitching beam lock head 1, and the front end of the pitching beam locking head 1 is set as an arc surface, so that the lower end of the floating pin 5 is better matched with the front end of the pitching beam lock head 1 , a locking hole 101 which is matched with the lower end of the floating pin 5 is opened on the pitching girder lock head 1 near its arc surface.

A fixed block 7 is installed on the upper surface of the fixed base 2 , and the fixed block 7 is arranged corresponding to the wedge surface of the floating pin 5 .

An anchor entry signal sensor 16 is installed on the short arm end 302 through the mounting bracket 15 to detect the anchor entry signal of the pitch beam lock head 1 .

An anchor signal sensor 18 and a displacement signal sensor 19 are installed on the upper surface of the long arm end 301 through the mounting bracket 17 to detect the up and down movement signal of the floating pin 5 .

The function of the floating pin 5 is to cooperate with the fixed stopper 7 to fix the pitching beam lock head 1 to prevent the pitching beam locking head 1 from sliding down.

The function of the floating arm 10 is to move the floating arm 10 up and down under the action of the electric push rod 9 to drive the floating pin 5 to move up and down around the fixed pin 6 .

The electric push rod 9 stretches out in a normal state. When receiving the command to unload the anchor, the electric push rod 9 shrinks and drives the floating arm 10 to move up.

The working principle of the automatic anchoring device of the present invention is as follows:

When entering the anchor: the pitching beam lock head 1 moves forward and contacts the floating pin 5. Since the floating pin 5 can move up and down and rotate around the fixed pin 6, the floating pin 5 is jacked up and the lower end of the floating pin 5 is inserted into the pitching beam locking head 1 In the locking hole 101, the pitching girder lock head 1 is automatically anchored under the action of the fixed block 7. At this time, the anchoring signal sensor 16 detects the anchoring.

When the anchor is released: the electric push rod 9 retracts and drives the floating arm 10 to lift up, thereby causing the floating pin 5 to move upward. When the moving stroke of the floating pin 5 rises to a certain height, the displacement signal sensor 19 receives the signal. At this time, the displacement The signal sensor 19 sends out an anchor signal, and the tilting beam locking head 1 moves backwards so that the lower end of the floating pin 5 exits the locking hole 101 . When the pitching beam lock head 1 is completely withdrawn, the anchor signal sensor 18 detects that the floating pin 5 reaches the limited position and sends out a signal, and the electric push rod 9 stretches out to drive the floating arm 10 to move downward, thereby causing the floating pin 5 to return to initial position.

The automatic anchoring device of the present invention cleverly utilizes the characteristics of the floating pin 5 to lift the floating pin 5 forward by the tilting beam lock head 1 to automatically enter the anchor. It is good to withstand the force generated by the sliding of the pitch girder lock head 1. When pulling out the anchor, only the electric push rod 9 needs to be retracted, and the floating arm 10 is driven to raise the floating pin 5 to complete the action of pulling out the anchor.

Those skilled in the art should realize that the above embodiments are only used to illustrate the present invention, but not to limit the present invention. Changes and modifications will fall within the scope of the claims of the present invention.
