Description

Technical Field

[0001] The utility model relates to the technical field of quay crane anti-collision, in particular to an early warning device for quay crane anti-collision. Background Art

[0002] The large-scale container transport ships, especially the development of post-Panamax ships, have put forward newer and higher requirements for shore container cranes: first, to improve the technical parameters of the cranes, increase the speed parameters of the cranes, increase the outreach and lifting height, and increase the rated lifting capacity under the spreader; second, to develop and design efficient shore container loading and unloading systems to meet the requirements of large-scale ships for crane productivity.

[0003] For example, the patent document with the announcement number CN 214879690 U discloses a safety device for preventing a large vehicle from collision on a quayside bridge, which relates to the technical field of anti-collision facilities for container quayside bridges, and includes a fixed seat connected to a large vehicle on the quayside bridge, a shock-absorbing mechanism for shock absorption, a shell for preventing collision, and a contact sensor for sensing an impacting object. The shock-absorbing mechanism is arranged on the front end face of the fixed seat, and the shell is arranged on the front end face of the shock-absorbing mechanism. A contact sensor is fixedly arranged on the upper end face of the shell, and the contact sensor is electrically connected to an alarm. By setting up the shell, the damage caused by the impacting object to the large vehicle on the quayside bridge can be reduced; by setting up the shock-absorbing mechanism, the vibration generated by the large vehicle on the quayside bridge when it is hit can be reduced, thereby improving the anti-collision performance of the device; by setting up the contact sensor and the alarm, while the shell reduces the damage caused by the impacting object to the large vehicle on the quayside bridge, an alarm is issued to remind the operator, and the structure is simple and the operation is convenient, thereby improving the convenience of the device.

[0004] However, when docking the quay crane container, due to the limitation of its own structure, this structure cannot maintain the adaptive anti-collision guiding operation between the quay crane spreader and the container from beginning to end. In actual use, abnormal collision problems are still prone to occur, which damages the spreader and the container. At the same time, the equipment cannot perform efficient limiting operations on the entire container and cannot meet daily use needs. Therefore, it is urgent to design an anti-collision warning device for the quay crane to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an early warning device for anti-collision of a quay crane, so as to solve the problem that the existing structure proposed in the above background technology cannot maintain the adaptive anti-collision guiding operation between the quay crane hoist and the container from beginning to end due to the limitation of its own structure when docking the quay crane container, and is still prone to abnormal collision during actual use, damaging the hoist and the container. At the same time, the equipment cannot perform efficient limiting operations on the entire container and cannot meet daily use needs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an early warning device for anti-collision of a quay crane, comprising a hanging frame, a supporting seat is fixedly connected to the bottom end of the hanging frame, a reinforcement seat is arranged at the inner center of the hanging frame, an infrared positioning frame is arranged at the edge of the reinforcement seat, and a first infrared probe is arranged at the four corners of the bottom of the hanging frame;

[0007] The stripping oblique frame is fixedly connected to the two ends of the lifting frame, a lifting push rod is arranged at the bottom of the stripping oblique frame, and a rotating plate frame is movably connected inside the stripping oblique frame.

[0008] Preferably, a movable shaft is provided at one end of the lifting push rod, and a damping rubber cover is provided on the inner wall of the stripping inclined frame.

[0009] Preferably, a conveying roller is provided on the surface of the rotating plate frame, and a rotating shaft is provided at one end of the rotating plate frame.

[0010] Preferably, both ends of the surface of the hanging frame are fixedly connected with limiting side plates, and limiting push rods are evenly arranged inside the limiting side plates.

[0011] Preferably, one end of the limit push rod is fixedly connected to a limit bar frame, and an inner wall of the limit bar frame is provided with a limit inclined groove.

[0012] Preferably, both ends of the first infrared probe are fixedly connected to infrared positioning seats, and a second infrared probe is arranged on the surface of the infrared positioning seat.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The anti-collision warning device for the quay crane can realize efficient anti-collision warning operation when hoisting the quay crane through the setting of the hoisting frame, the supporting seat, the reinforcing seat, the infrared positioning frame, the first infrared probe, the limit side plate, the limit push rod, the limit bar frame, the limit inclined groove, the infrared positioning seat and the second infrared probe. In the actual use process, the staff can quickly dock the hoisting tool to the position between the limit side plates on the top of the hoisting frame. At this time, the limit push rod inside the limit side plate is first started to dock the two sets of limit bar frames to the two sides of the hoisting tool, so that the limit inclined groove on the inner wall of the limit bar frame can be adaptively fitted to the quay crane. On both sides of the bridge hoist, the limit bar frame is slowly lowered to adapt the hoist to fall onto the surface of the hoisting frame in an anti-collision manner, and the anti-collision hoisting operation of the container on the surface of the hoisting frame is performed. At the same time, when the hoist is docked with the limit bar frame, the infrared positioning seat and the second infrared probe at both ends of the limit bar frame can perform a four-point infrared preliminary hoist positioning operation. When descending afterwards, the first infrared probe of the fourth level at the bottom of the hoisting frame can be started, and a large area of ​​infrared positioning can be performed through the infrared positioning frame on the surface of the hoisting frame to ensure that the hoisting is adjusted to the anti-collision state at all times, which reflects the practicality of the equipment design.

[0015] The anti-collision warning device for the quay crane further improves the overall use effect of the equipment through the setting of the lifting frame, stripping inclined frame, jacking push rod, rotating plate frame, movable shaft, damping rubber cover, conveying roller and rotating shaft. In the daily use process, the container that needs to be lifted by the quay crane can be sent along the stripping inclined frame to the surface of the lifting frame for support and stability through the reinforced seat. The container can be stably rolled and conveyed on the surface of the stripping inclined frame through the conveying roller on the surface of the rotating plate frame. Then the jacking push rod at the bottom of the stripping inclined frame is started, and the rotating plate frame as a whole can be rotated and adjusted along the rotating shaft inside the damping rubber cover of the stripping inclined frame in cooperation with the movable shaft at one end, so as to realize the stable limit protection operation on both sides of the container, which reflects the comprehensiveness of the equipment design.
