Description

Technical Field

[0001] The present invention relates to auxiliary equipment of an automated wharf quay crane, and more specifically to a transfer platform of an automated wharf quay crane, which is particularly suitable for a wharf adopting full / semi-automation or remote operation, and is also suitable for a double-trolley quay crane. Background Art

[0002] With the increasing size of global ships and the rising labor costs, large container ports are currently taking automated terminals as their construction direction. Since the ECT terminal of the Port of Rotterdam in Europe was put into operation in 1993, the exploration and practice of automated terminals around the world have continued to deepen, and great results have been achieved, including the innovation of loading and unloading machinery and processes at the forefront of automated terminals. The shore crane of the automated terminal has experienced a development process from a single trolley crane to a double trolley crane. Since the double trolley crane has greatly improved the loading and unloading efficiency at the forefront of the terminal, when funds and terminal conditions permit, all ports generally tend to choose double trolley shore cranes as the main loading and unloading equipment. Compared with conventional container quay cranes, the biggest difference between double trolley shore cranes and conventional container quay cranes is that they are equipped with two fully automatic lifting trolleys. The traditional quay crane method of completing loading and unloading operations in one time has been replaced by the double trolley shore crane method of completing operations in two times, that is, the main trolley (sea side) is responsible for loading and unloading containers on the ship, transitioning through the transfer platform, and the auxiliary trolley (land side) is responsible for loading and unloading containers on the transfer platform and horizontal transport machinery.

[0003] It can be seen that the transfer platform is an important mechanism on the automated double-trolley shore container crane. It is the platform for transferring containers between the two trolleys of the shore crane during loading and unloading operations. Whether the layout of the transfer platform is reasonable will directly affect the hourly output of the terminal loading and unloading machinery and the ship loading and unloading operation time. It is also a key link in optimizing and improving the hourly output of the loading and unloading machinery. Therefore, the platform design should be suitable for the loading and unloading process of the terminal and should comply with the safety specifications of human-machine cooperation.

[0004] At present, the situation in each terminal is different, and there are many reasons for this. The needs of terminal users, the needs of electric control companies, the constraints of auxiliary equipment and other factors have led to the diversification of transfer platforms, and it is difficult to have a unified standard. Therefore, how to further optimize the functionality of the transfer platform to adapt it to the needs of most terminals and improve the efficiency of the interactive area operation has become a difficulty in the design and manufacture of the transfer platform. Summary of the invention

[0005] In view of the above-mentioned defects existing in the prior art, the object of the present invention is to provide a transfer platform for an automated terminal quay crane, optimize the functionality of the transfer platform to adapt it to the needs of most terminals, and at the same time improve the operating efficiency of the interactive area.

[0006] To achieve the above object, the present invention adopts the following technical solution:

[0007] A transfer platform for an automated quay crane at a dock, comprising a container pedestal and a container guide frame arranged on the side of the container pedestal;

[0008] The container pedestal is configured as a rectangular frame body, in which a lock pin frame is provided;

[0009] The container guide frame is configured as a frame body, the top of which is a container guide surface, and the bottom is a personnel passage;

[0010] Platform guide frames are also provided on the four sides of the container platform.

[0011] The container pedestal is provided with two groups of locking pin hanging points, and the opening distance between the two groups of locking pin hanging points is adapted to a 30-foot container.

[0012] There are several lock pin frames, all of which are installed in the container pedestal through lock pin frame supports.

[0013] The container guide frame includes a long container guide frame and a short container guide frame. There are two long container guide frames on the same side. Two short container guide frames are arranged between the two long container guide frames. The final number of container guide frames can be adjusted according to the number of containers that can be lifted by the quay crane at one time. A gap is formed between the long container guide frame and the short container guide frame, and between the short container guide frame and the short container guide frame.

[0014] The cross section of the guide surface at the top of the container guide frame is set to an isosceles triangle shape, which is composed of angle steel, channel steel and I-beam. The cross section of the personnel passage at the bottom of the container guide frame is set to a rectangle, which is composed of I-beam.

[0015] A safety net is also provided on the gap.

[0016] The safety net is made of steel sections.

[0017] The height of the container pedestal is set to 1300-1500 mm.

[0018] The pedestal guide frames at the two end positions of the container pedestal are high-type pedestal guide frames, and the pedestal guide frames at the two side positions in the length direction of the container pedestal are low-type pedestal guide frames.

[0019] The height of the high-type pedestal guide frame is greater than that of the low-type pedestal guide frame.

[0020] In the above technical solution, the transfer platform of the automated quay crane provided by the present invention also has the following beneficial effects:

[0021] 1) The transfer platform of the present invention can realize the container guide frame under the premise of ensuring lightweight, which can not only meet the container guidance function, but also serve as a maintenance personnel channel for disassembling and installing the container lock pin. At the same time, the user can selectively decide whether to install the top guardrail;

[0022] 2) The container guide frame of the transfer platform of the present invention and its installation position relative to the center line of the bridge crane can not only avoid the degree of eight-shaped when the double 20-foot containers (especially empty containers) are placed, and avoid the situation where the gantry trolley cannot lift, but also free up space to ensure that the container pedestal (30-foot position) can be lifted smoothly, and the container lock pin can be safely removed from the channel.

[0023] 3) The container pedestal of the transfer platform of the present invention is integrated with the lock pin frame and can be hoisted to the ground as a whole. The hoisting point of the pedestal is set at 30 feet, and a guide frame is set around the pedestal to facilitate the lifting or lowering of the pedestal. BRIEF DESCRIPTION OF THE DRAWINGS
