Description

Technical Field

[0001] The utility model relates to the technical field of quay crane hoisting equipment, in particular to a quick connection device for upper and lower frames of a quay crane hoisting equipment. Background Art

[0002] The quay crane is a part of the shore container crane (abbreviated as quay crane or bridge crane), which is used for loading and unloading container ships at container terminals. The quay crane is usually used to grab and move containers so that they can be unloaded from or loaded onto ships. The quay crane is one of the important equipment that cannot be ignored in the loading and unloading operations of container terminals, and plays an important role in improving loading and unloading efficiency, reducing labor costs and ensuring operation safety.

[0003] The upper frame and lower frame of the quay crane spreader are two important components of the quay crane spreader, and they play a vital role in the loading and unloading process of containers. The upper frame is the upper structure of the spreader, and its main function is to grab and fix the container for transportation and loading and unloading. The lower frame is the lower structure of the spreader, and its main function is to connect the upper frame and the crane, so that the spreader can perform vertical lifting and lowering movements under the action of the crane, thereby realizing the lifting and unloading of the container.

[0004] The process of connecting the upper and lower frames of the hoisting equipment of the quay crane equipment is very demanding on the cooperation between the driver and the maintenance personnel. The lock head needs to be aligned with the lock hole for the upper and lower frames to be connected. The maintenance personnel need to support and align it with their hands during the connection process, which increases the instability of the operation and easily creates safety risks. In addition, it is very inconvenient and time-consuming to rely solely on the operation of relevant personnel to align the lock hole position, which cannot meet the busy production needs on site and has major drawbacks. Utility Model Content

[0005] In view of the technical problem that the upper and lower frames of the quay crane hoist are difficult to connect quickly in the prior art, the utility model provides a quick connection device for the upper and lower frames of the quay crane hoist, which is easy to install and can be installed immediately after disassembly, and can achieve quick connection. It overcomes the drawback of the prior art of unreasonable manual connection of the upper and lower frames of the hoist relying on personnel experience, ensures the safety of maintenance personnel, and improves work efficiency.

[0006] The utility model provides a quick connection device for upper and lower frames of a quay crane hoist, comprising a mounting seat, a magnet is fixed on the side of the mounting seat, and the mounting seat is provided with a detachably connected guide plate, the guide plate is vertically downward.

[0007] Furthermore, the mounting seat has a mounting cavity inside, the two ends of the mounting cavity are open, and the side plate of the mounting seat is provided with a sliding slit. The function of the sliding slit is that it has a sliding length and can adjust the lateral mounting position of the guide plate.

[0008] Furthermore, it also includes a bolt, the head of the bolt is located in the installation cavity, the threaded rod of the bolt passes through the sliding gap and the guide plate, the bolt is provided with a nut matching with it, and the bolt and the nut cooperate to fix the mounting seat and the guide plate.

[0009] Furthermore, a U-shaped lifting lug is welded on the guide plate. Furthermore, a chain is connected to the U-shaped lifting lug. The U-shaped lifting lug can be connected to the sling through the chain, so as to prevent the guide plate from falling when the guide plate is not fixed firmly, thereby providing a safety function.

[0010] Furthermore, the lower part of the guide plate is a guide section, and the guide section is V-shaped. The function is that the width of the lower part of the guide plate gradually decreases from top to bottom to form a V-shape, which can provide a guiding effect with the help of the limit of the lower frame of the spreader. The upper frame will automatically align according to the guide of the guide plate. Even if there is a partial error during the connection process, the guide plate mechanism will automatically reset the upper frame, making the connection of the upper and lower frames of the overall spreader fast and efficient, and improving the guiding effect.

[0011] The beneficial effects of the utility model are as follows: the utility model is easy to install, can be installed and disassembled at the same time, and can achieve quick connection. The guiding effect of the guide plate can be utilized to automatically align the upper and lower frames of the spreader. There is no need to manually connect the upper and lower frames of the spreader relying on the experience of the operator as in the prior art, so that the connection work of the upper and lower frames of the quay crane spreader is more scientific, convenient and standardized, thereby ensuring the safety of maintenance personnel and improving work efficiency.
