Description

TECHNICAL FIELD

[0001] The present application relates to the field of crane manufacturing and installation, in particular to a deviation rectification and track falling method for a shore-based container crane. BACKGROUND

[0002] With the continuous development of global trade, the container transportation business is increasing, and various container loading and unloading wharfs are continuously increasing. The shore-based container crane (hereinafter referred to as the shore crane) is also developing in a large scale. In the busy loading and unloading process of various wharfs, the shore crane plays an important role, but in the operation process, various unpredictable accidents may occur, such as sudden movement of the shore crane caused by sudden strong wind, collision between the shore cranes, sudden movement of the container ship under the shore crane, or collision with the shore crane due to operation error when stopping, etc. This may easily cause one or more shore cranes to be damaged and derailed (as shown in FIG. 1), or even overturned. Such accidents will have a serious impact on the normal production and operation of the wharf. Figure 1

[0003] When the above problems occur, it is an important consideration to restore the normal operation of the wharf as soon as possible. In addition to the necessary temporary reinforcement of the damaged and derailed shore crane, it is also necessary to rectify the deviation and fall the track, so that it can be moved to the non-normal operation area on the track, thereby reducing the impact on the wharf operation.

[0004] The conventional treatment method usually needs to use large lifting equipment to lift the whole machine and place it on the track after being properly positioned, or even may need to dismantle the shore crane in place. This method needs large equipment, has a long operation period, is high in cost, and needs a suitable wharf and position for operation, so the feasibility is poor.

[0005] Therefore, the present application provides a deviation rectification and track falling method for a shore-based container crane to overcome the above technical problems. SUMMARY

[0006] The technical problem solved by the present application is to overcome the defects of the prior art that the shore crane is easily damaged and derailed, or even overturned, and to provide a deviation rectification and track falling method for a shore-based container crane.

[0007] The present application solves the above technical problems by the following technical scheme:

[0008] The present application provides a deviation rectification and track falling method for a shore-based container crane, characterized in that the deviation rectification and track falling method comprises the following steps:

[0009] S1, arranging a load distribution beam and a vertical jack assembly under the balance beam of the large truck running mechanism on the sea side of the shore crane;

[0010] ​S2, welding horizontal jacking supports on the load distribution beam, and arranging horizontal jacks on the horizontal jacking supports for jacking the vertical jack assembly to make the vertical jack assembly produce displacement in the horizontal direction;

[0011] S3, arranging a tractor on the side of the moving direction of the land-side trolley traveling mechanism of the quay crane, and fixing the tractor with the balance beam of the land-side trolley traveling mechanism of the quay crane;

[0015] According to one embodiment of the present application, in the step S5, a temporary rigid track perpendicular to the trolley track is arranged under the jacking trolley.

[0016] According to one embodiment of the present application, in the step S5, the traction mechanism is a tractor or a winch.

[0017] According to one embodiment of the present application, between the step S2 and the step S3, a thick steel plate is arranged under the wheels of the land-side trolley traveling mechanism of the quay crane.

[0020] According to one embodiment of the present application, in the step S3, when the quay crane is rectified, the land-side trolley traveling mechanism of the quay crane and the sea-side trolley traveling mechanism of the quay crane simultaneously produce force.

[0021] According to one embodiment of the present invention, in step S1, the vertical jack assembly and the load-bearing beam have a smooth and flat contact. The vertical jack assembly lifts the balance beam on the sea side of the quay bridge, so that the wheels of the trolley traveling mechanism on the sea side of the quay bridge are lifted into the air.

Preferred embodiments of the invention will now be described in detail, examples of which are shown in the drawings. Wherever possible, the same reference numerals will be used in all the drawings to denote the same or similar parts.

[0053] Furthermore, although the terminology used in this invention is selected from commonly known and used terms, some terms mentioned in this specification may have been selected by the applicant in his or her judgment, and their detailed meanings are explained in the relevant sections of the description herein.

[0054] Furthermore, the invention should be understood not only through the actual terminology used, but also through the meaning implied by each term.

[0055] like Figures 2 to 6 As shown, this invention discloses a method for correcting deviation and lowering the track for a quay container crane, which includes the following steps:

[0056] Step S1: Arrange the load-sharing beam 30 and the vertical jack assembly under the balance beam 20 of the trolley traveling mechanism 10 on the sea side of the shore bridge.

[0057] More specifically, preferably, a relatively long rigid load-sharing beam 30 is arranged on the ground corresponding to the large balance beam 20 on the sea side of the quay crane. The load-sharing beam 30 needs to span the longitudinal beams on the wharf. A thick steel plate (not shown in the figure) is welded to the upper part of the load-sharing beam 30.

[0058] The upper surface of the thick steel plate here needs to be smooth and flat; for example, lubricating grease can be applied to the thick steel plate. At the same time, a vertical jack support 40 is arranged on the upper part of this thick steel plate. The bottom surface of the vertical jack support 40 needs to be ground smooth and flat. A large-tonnage vertical jack 41 is arranged on the vertical jack support 40, and a pad beam 31 is arranged on the upper part of the vertical jack 41. The vertical jack 41 is used to lift the balance beam 20 on the sea side of the quay crane, so that the wheels of the trolley traveling mechanism 10 on the sea side of the quay crane are lifted into the air.

[0059] Preferably, in step S1, the vertical jack assembly and the load-bearing beam have a smooth and flat contact. The vertical jack assembly lifts the balance beam on the sea side of the quay crane, thus suspending the wheels of the trolley traveling mechanism on the sea side of the quay crane. To ensure smoothness between the vertical jack assembly and the load-bearing beam, lubricating oil or grease can preferably be applied between them.

[0060] Step S2: Weld a horizontal lifting support 60 onto the load-bearing beam 30, and arrange a horizontal jack 61 on the horizontal lifting support 60 to lift the vertical jack assembly, so that the vertical jack assembly produces a horizontal displacement.

[0061] The process between steps S2 and S3 further includes: placing a thick steel plate 50 under the wheels of the trolley traveling mechanism 40 on the land side of the quay crane to facilitate the trolley wheels sliding sideways on the steel plate when the whole machine is rotating to correct its deviation.

[0062] The vertical jack assembly preferably includes a vertical jack base 60 and a vertical jack 61, with the vertical jack base 60 arranged on a thick steel plate 50 and the vertical jack 61 installed on the vertical jack base 60.

[0063] Step S3: Arrange a tractor 80 on one side of the moving direction of the trolley traveling mechanism 70 on the land side of the quay crane, and fix it to the balance beam of the trolley traveling mechanism 70 on the land side of the quay crane.

[0064] Preferably, the traction mechanism 70 can be configured as a tractor or a winch. In step S3, when the entire quay crane is correcting its course, the trolley travel mechanism on the sea side and the trolley travel mechanism on the land side of the quay crane exert force simultaneously.

[0065] In step S3, the tractor 80 is fixedly connected to the ear plate on the balance beam of the trolley traveling mechanism 70 on the land side of the quay crane via a steel wire rope and shackle 81, so as to ensure that the position of the trolley traveling mechanism 10 on the sea side of the quay crane and the position of the trolley traveling mechanism 70 on the land side of the quay crane exert force simultaneously when the whole machine is corrected.

[0066] Step S4: The horizontal jack 61 adjusts the position of the gantry crane traveling mechanism 10 on the sea side of the quay crane in the sea-land direction, and the tractor 80 adjusts the gantry crane traveling mechanism 70 on the land side of the quay crane in the left-right direction, so that the entire quay crane rotates and corrects the deviation of the entire quay crane.

[0067] Furthermore, the step S4 is followed by the following steps:

[0068] Step S5: When the entire quay crane rotates until the wheels of the trolley travel mechanism (including the trolley travel mechanism 10 for quay crane sea surveying and the trolley travel mechanism 70 for quay crane landside) are parallel to the quay crane track, a lifting trolley 90 is arranged under the balance beam of the trolley travel mechanism (including the trolley travel mechanism 10 for quay crane sea surveying and the trolley travel mechanism 70 for quay crane landside). The trolley lifts the entire quay crane and uses a traction mechanism to pull the lifting trolley to move in the sea-land direction until the wheels of the trolley travel mechanism are aligned with the quay track. Then, the lifting trolley is lowered to lower the wheels of the trolley travel mechanism (including the trolley travel mechanism 10 for quay crane sea surveying and the trolley travel mechanism 70 for quay crane landside) onto the quay track.

[0069] Preferably, in step S5: a temporary rigid track perpendicular to the main track is arranged under the lifting trolley.

[0070] In summary, the present invention provides a method for correcting and lowering the quay crane onto the rails, which achieves overall crane correction and lowering through a sliding mechanism. This method reduces the impact on the user's terminal operations, improves operational efficiency, avoids the use of large lifting equipment, and lowers costs.
