Description

Technical Field

[0001] The invention relates to an anchoring device for a pitching mechanism of a quay crane, and more particularly to an automatic anchoring device for a pitching mechanism of a quay crane. Background Art

[0002] At present, there are mainly two types of pitching anchoring mechanisms for quay cranes:

[0003] 1) The manual bolt anchoring method requires the operator to climb above the ladder frame to manually operate, but this method is time-consuming and laborious, and cannot be operated automatically;

[0004] 2) Anchoring method of lifting and dropping hook motor, such as Figure 1 As shown:

[0005] Hooking: When the program gives the hooking action signal, the pitching beam lock 20 moves forward to trigger the hook area limit deceleration switch 21, and the motor push rod 22 moves to lift the hook body 25. When it is lifted to a certain angle, it triggers the lifting hook limit switch 23 and the lifting stops. At this time, the pitching beam lock 20 continues to move forward. When the hook area end limit switch 24 is triggered, the pitching beam lock 20 stops moving. At the same time, the motor push rod 22 moves to make the hook body 25 fall, so that the hook head 25 hooks the pitching beam lock 20 to prevent it from sliding down. At this time, the hooking action is completed.

[0006] Hook out: When the program gives a hook action signal, the motor push rod 22 moves to lift the hook body 25. When it is lifted to a certain angle, the lifting hook limit switch 23 is triggered and the lifting stops. Then the pitch beam lock 20 moves backward. When the hook area limit deceleration switch 21 signal is restored, the motor push rod 22 moves to make the hook body 25 fall down. At this time, the hook out action is completed.

[0007] However, this method has the disadvantages of large size, complex structure, high manufacturing cost, cumbersome installation, and high subsequent maintenance cost. Summary of the invention

[0030] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0031] Please combine Figures 1 to 4 As shown, an automatic anchoring device of a quay crane pitching mechanism provided by the present invention cooperates with a pitching beam lock 1, and includes a fixed base 2, to which a mounting panel 3 is connected, the mounting panel 3 is arranged in an L shape, the long arm end 301 of the mounting panel 3 is arranged horizontally, and the short arm end 302 of the mounting panel 3 is connected and fixed vertically downward to the upper surface of the fixed base 2.

[0032] A through hole 4 is formed on the long arm end 301 , and a vertically arranged floating pin 5 is installed in the through hole 4 . The floating pin 5 is movably connected in the through hole 4 via a fixing pin 6 .

[0033] The floating pin 5 is provided with a vertical waist-shaped through hole 501 , into which the fixing pin 6 is inserted, so that the floating pin 5 can move up and down around the fixing pin 6 .

[0034] 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 an electric push rod base 8 , and a movable rod on the electric push rod 9 is connected to the upper end of the floating pin 5 through a floating arm 10 .

[0035] Two connecting holes 1001 arranged in an upper and lower arrangement are provided on the rear end of the floating arm 10. The upper connecting hole 1001 is connected to the movable rod on the electric push rod 9 through a first fixed pin 11, and the lower connecting hole 1001 is connected to an ear plate 13 through a second fixed pin 12. The ear plate 13 is fixed on the upper surface of the long arm end 301.

[0036] A waist-shaped arc-shaped through hole 1002 is opened on the front end of the floating arm 10 , and the waist-shaped arc-shaped through hole 1002 is connected to the upper end of the floating pin 5 through the latch fixing pin 14 .

[0037] The lower end of the floating pin 5 is set as a wedging surface toward the pitch beam lock 1, and the front end of the pitch beam lock 1 is set as an arc surface, so that the lower end of the floating pin 5 and the front end of the pitch beam lock 1 can better match each other, and a locking hole 101 that is compatible with the lower end of the floating pin 5 is opened on the pitch beam lock 1 near its arc surface.

[0038] A fixed stopper 7 is installed on the upper surface of the fixed base 2 , and the fixed stopper 7 is arranged corresponding to the wedging surface of the floating pin 5 .

[0039] An anchoring signal sensor 16 is installed on the short arm end 302 through a mounting bracket 15 to detect the anchoring signal of the pitch beam lock 1.

[0040] An anchor signal sensor 18 and a displacement signal sensor 19 are mounted on the upper surface of the long arm end 301 via a mounting bracket 17 to detect the up and down movement signals of the floating pin 5 .

[0041] The function of the floating pin 5 is to fix the pitch beam lock 1 together with the fixed stopper 7 to prevent the pitch beam lock 1 from sliding down.

[0042] The function of the floating arm 10 is to make the floating arm 10 move up and down under the action of the electric push rod 9, thereby driving the floating pin 5 to move up and down around the fixed pin 6.

[0043] The electric push rod 9 is extended in a normal state. When receiving the anchor release command, the electric push rod 9 is retracted to drive the floating arm 10 to move upward.

[0044] The working principle of the automatic anchoring device of the present invention is as follows:

[0045] When anchoring: the pitching beam lock 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 lifted up and the lower end of the floating pin 5 is inserted into the locking hole 101 on the pitching beam lock 1. Under the action of the fixed stop block 7, the pitching beam lock 1 is automatically anchored. At this time, the anchoring signal sensor 16 detects the anchoring.

[0046] When unanchoring: the electric push rod 9 retracts and drives the floating arm 10 to lift, thereby causing the floating pin 5 to move upward. When the floating pin 5 moves to a certain height, the displacement signal sensor 19 receives a signal. At this time, the displacement signal sensor 19 sends an unanchoring signal, and the pitch beam lock 1 moves backward to cause the lower end of the floating pin 5 to exit the locking hole 101. When the pitch beam lock 1 is completely withdrawn, the unanchoring signal sensor 18 detects that the floating pin 5 has reached a limited position and sends a signal. The electric push rod 9 extends and drives the floating arm 10 to move downward, thereby causing the floating pin 5 to return to its initial position.

[0047] The automatic anchoring device of the present invention cleverly utilizes the characteristics of the floating pin 5, and automatically anchors by pushing up the floating pin 5 through the forward movement of the pitch beam lock 1. When the pitch beam lock 1 slides down, it cooperates with the fixed stopper 7 to well withstand the force generated by the downward movement of the pitch beam lock 1. When unanchoring, it only needs to retract the electric push rod 9 to drive the floating arm 10 to raise the floating pin 5 to complete the unanchoring action.

[0048] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
