[0002] A crane refers to a multi-action lifting machine that vertically lifts and horizontally transports heavy objects within a certain range. It is also called an overhead crane, a bridge crane, or a hoist. Unmanned cranes are widely used in intelligent production workshops. By using industrial network technology, information is collected from the electric control system of the crane, enabling real-time and comprehensive monitoring of the working state of the crane. The crane is operated using remote services and remote monitoring to ensure safe and efficient lifting operations.

[0003] The "Infrared Obstacle Avoidance Device and Crane" disclosed in its application number "CN202320605911.1" "comprises: a fixed frame and a control circuit; the fixed frame is fixedly sleeved on the crane hook, the fixed frame has four sides respectively corresponding to the four moving directions of the crane hook, and infrared distance sensors are fixedly arranged on the sides; the control circuit has a control module, and a trolley relay and a crab relay are connected to the control module; the infrared distance sensors are connected to the control module". In the utility model, through four infrared distance sensors respectively arranged on the four sides of the fixed frame, the distances to objects in the front, rear, left, and right directions of the crane hook can be automatically detected and sent to the control module. An early warning distance value is set inside the control module. During the movement of the crane hook, when the infrared distance sensor detects that the distance to an object is less than or equal to the early warning distance value, the crane trolley and crab will immediately stop moving.

[0004] However, the above method still has the following defects: Since the infrared distance sensor is fixed on the fixed frame and does not have an angle adjustment function, the coverage range is small. When lifting objects at different heights, the height between the hook and the ground will be different. The infrared distance sensor is in a horizontal state, and it is difficult to cover the ground when the hook is relatively high, and it is difficult to flexibly adjust the angle of the infrared distance sensor.

An alarm can be set in the remote operation room and connected to the monitoring radar 18, and an alarm can be issued through the alarm when an obstacle is encountered;

[0035] When the monitoring radar 18 is working, the cylinder 2 can support between the support ring 3 and the positioning ring 1, and can maintain the distance between the support ring 3 and the positioning ring 1. Subsequently, the inclination angle of the monitoring radar 18 can be maintained. When lifting objects at different heights results in different heights between the hook and the ground, the support ring 3 is driven to lift and lower by the cylinder 2. When the support ring 3 lifts and lowers, it can change the attitude of the connecting rod 15, and the connecting rod 15 can adjust the angle of the adjusting rod 14, so that the angles of the four monitoring radars 18 can be quickly adjusted simultaneously. When the height of the hook seat is relatively high and it is difficult to cover the ground, by flexibly adjusting its angle, the coverage range can be increased, ensuring that the monitoring radar 18 can cover the ground and reducing potential safety hazards;

[0036] During the adjustment process, the optical rod 1303 and the guide frame 1304 of the strengthening component 13 can play a guiding role and strengthen the support ring 3, making the support ring 3 not easy to deform and tilt. When the monitoring radar 18 needs to be disassembled, the staff loosens the bolt 1605 fixing the limit block 1604 and removes it, and then pulls out the limit block 1604 from the card slot 1606 of the mounting seat 1603, and the monitoring radar 18 can be disassembled for maintenance activities of the monitoring radar 18.
