[0002] A crane refers to a multi-action lifting machine that vertically lifts and horizontally transports heavy objects within a certain range. Some working characteristics of lifting equipment are intermittent movements, that is, in a working cycle, the corresponding mechanisms for actions such as material taking, transporting, and unloading work alternately. The development and use of cranes in the market are becoming more and more extensive. The core components of a crane include a boom, a hook, a traveling mechanism, and a main control system. The boom is its main structure and is responsible for carrying and lifting goods; the hook is located at the end of the boom and is used to connect and suspend objects. Since the surrounding environment during the operation of the crane is crucial for lifting items, it is necessary to carry out self-weight warning work.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part rather than all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without any creative effort shall fall within the protection scope of the present utility model.

[0032] Referring to Figures 1 - 5 , the present utility model provides a technical solution: a real-time warning device for a crane, including a support rod 1 and a passive warning mechanism. The right side of the support rod 1 is movably connected to a secondary rod 2, and control boxes 3 are installed on the front sides of both the secondary rod 2 and the support rod 1. When the support rod 1 and the secondary rod 2 are in use, generally, the user can perform a wire-pulling warning operation on the outer working area of the crane according to the actual working requirements of the external crane, so as to avoid the situation of dangerous accidents caused by unrelated external personnel entering the working area. Therefore, the convenience of warning zoning for the support rod 1 and the secondary rod 2 is improved.

[0033] Referring to Figures 1 - 5, in a preferred embodiment, the passive warning mechanism includes a warning box 4, which is fixedly connected to the top of the support rod 1. A warning belt 5 is movably connected inside the warning box 4. A connecting column 6 is fixedly connected to the inner wall of the warning box 4. A connecting cylinder 7 is rotatably connected to the surface of the connecting column 6. The surface of the connecting cylinder 7 is fixedly connected to one end of the warning belt 5. A docking head 8 is fixedly connected to the other end of the warning belt 5. A docking seat 9 that is movably connected to the docking head 8 is fixedly connected to the top of the auxiliary rod 2. The active warning structure is arranged on the front side of the support rod 1. According to the actual working requirements of the external crane, first hold the docking head 8 and cooperate with the docking seat 9 to perform the docking connection operation between the warning belt 5 and the auxiliary rod 2. Then place the support rod 1 at the starting end of the wire-pulling partition, and hold the auxiliary rod 2 to drive the warning strip to move towards the other end of the partition through the connecting head and the connecting seat, so that a partition warning line is formed outside the working area of the crane, facilitating the staff to perform the partition warning operation on the working area. The active warning mechanism includes an infrared emitter 10, an infrared receiver 11, and an alarm 12. The infrared emitter 10 is movably connected to the front side of the support rod 1. The left side of the infrared emitter 10 is fixedly connected to the right side of the control box 3 on the front side of the support rod 1. The infrared receiver 11 is fixedly connected to the left side of the control box 3 on the front side of the auxiliary rod 2. The alarm 12 is fixedly connected to the top of the control box 3. The infrared emitter 10, the infrared receiver 11, and the alarm 12 are all electrically connected to the control box 3 through wires. When the warning belt 5 is used in cooperation with the support rod 1 and the auxiliary rod 2, it can perform real-time monitoring and warning work on the personnel outside the warning belt 5, and emit a beeping alarm sound when a person approaches to warn irrelevant personnel to stay away, avoiding the situation that it is difficult to give an audible warning to the surrounding personnel when the warning belt 5 is used. Therefore, the warning reminder effect of the warning belt 5 is improved.

[0034] Refer to Figures 3 - 4 , in a preferred embodiment, a force application cavity 13 is provided in the inner wall of the connecting cylinder 7, and a spring 14 is arranged inside the force application cavity 13. One end of the spring 14 is fixedly connected to the inner wall of the force application cavity 13, and the other end of the spring 14 is fixedly connected to the surface of the connecting column 6. When the connecting cylinder 7 is used in cooperation with the warning belt 5, the connecting cylinder 7 can provide a winding and tensioning force for the warning belt 5, avoiding the situation that the warning belt 5 sags and loosens when in use. Therefore, the warning tightness effect of the warning strip is improved. A card slot 15 is provided at the top of the docking seat 9, and a card frame 16 is movably connected inside the card slot 15. The left side of the card frame 16 is fixedly connected to the right side of the docking head 8. When the docking seat 9 is used in cooperation with the docking head 8, it can perform the docking and clamping anti-disengagement work between the docking head 8 and the docking seat 9, avoiding the situation that the docking head 8 separates from the docking seat 9 during operation. Therefore, the docking connection stability between the docking head 8 and the docking seat 9 is improved.

[0035] Refer to Figures 2 - 5, in a preferred embodiment, lifting grooves 17 are respectively formed at the bottoms of the front sides of the support rod 1 and the auxiliary rod 2. A lifting seat 18 is movably connected inside the lifting groove 17. When the pressing plate 19 and the pressing column 20 are used, it is convenient for the user to move the pressing plate 19 and the pressing column 20 at the bottoms of the front sides of the support rod 1 and the auxiliary rod 2 up and down according to the size of the warning sign displayed outside, so as to perform pressing and positioning operations on warning signs of different sizes, avoiding the situation that it is difficult to move and use the pressing plate 19 and the pressing column 20 during use. Therefore, the flexibility of use of the pressing column 20 and the pressing plate 19 is improved. The tops of the front sides of the support rod 1 and the auxiliary rod 2 and the front side of the lifting seat 18 are movably connected with pressing plates 19 respectively. A pressing column 20 is fixedly connected to the outside of the pressing plate 19. When the support rod 1 is used in cooperation with the auxiliary rod 2, it can provide a medium for the user to fix the warning sign or the instruction sign, so that the user can perform warning and instruction operations on pedestrians, avoiding the situation that it is difficult to give information warning and instruction to pedestrians when the support rod 1 and the auxiliary rod 2 are used. Therefore, the comprehensiveness of use of the support rod 1 and the auxiliary rod 2 is improved.

[0036] Refer to Figures 2 - 5 , in a preferred embodiment, a threaded groove 21 is formed at the rear side of the pressing column 20. A screw rod 22 is threadedly connected inside the threaded groove 21. The rear sides of the screw rod 22 are respectively fixedly connected to the front sides of the support rod 1, the auxiliary rod 2 and the lifting seat 18. When the pressing column 20 and the pressing plate 19 are used, a force-applying medium for threaded connection can be applied between the pressing plate 19 and the connecting seat, the support rod 1 and the auxiliary rod 2, avoiding the situation that it is difficult to apply actual pressing and positioning force to the external machine warning sign or instruction sign when the pressing column 20 and the pressing plate 19 are used. Therefore, the pressing and positioning effect of the pressing plate 19 and the pressing column 20 is improved. A magnetic strip 23 is inlaid and connected to the rear side of the inner wall of the lifting groove 17. A magnetic sheet 24 magnetically connected to the magnetic strip 23 is inlaid and connected to the rear side of the lifting seat 18. When the lifting seat 18 is used in cooperation with the screw rod 22, a magnetic absorption pre-positioning operation can be performed on the screw rod 22 located at the bottoms of the front sides of the support rod 1 and the auxiliary rod 2 through the lifting seat 18, avoiding the situation that it is difficult to perform pre-positioning when the screw rod 22 is used. Therefore, the convenience of use of the screw rod 22 is improved.

[0037] Specifically, the working process or principle of the real-time warning device for a crane is as follows: When in use, according to the actual working area requirements of the external crane, first hold the docking head 8 and drive the clamping frame 16 to move to the top of the docking seat 9 and align it with the card slot 15, and then move the docking head 8 downward to drive the clamping frame 16 into the internal of the card slot 15 to carry out the stable clamping and docking work between the docking head 8 and the docking seat 9, so that the warning tape 5 is connected to the auxiliary rod 2. Then, place the support rod 1 at the starting end of the wire-pulling area, and hold the auxiliary rod 2 to drive the warning strip to move to the other end of the area through the connector and the connecting seat, so that the warning strip forms a partition warning line outside the working area of the crane, so as to facilitate the staff to carry out the partition warning operation on the working area. At this time, the connecting cylinder 7 rotates on the surface of the connecting column 6 under the influence of the external tensile force of the warning tape 5 to carry out the rotational connection work between the warning tape 5 and the warning box 4. It should be noted that the support rod 1 and the auxiliary rod 2 are placed in a relatively parallel state. At the same time, the spring 14 rotates and stores energy through the force application cavity 13 following the connecting cylinder 7, applies a tension force to the warning tape 5 to ensure the tightness of the warning tape 5, and prepares for the subsequent winding of the warning tape 5 into the warning box 4. Subsequently, according to the actual situation, hold the external warning sign or instruction sign and move it to the front side of the auxiliary rod 2 and the support rod 1 and be located on the top of the lifting seat 18. Then, according to the actual size of the external warning sign and instruction sign, hold the pressing seat at the front side bottom of the support rod 1 and the auxiliary rod 2 to drive the pressing disc 19 to move, so that the front side and the bottom of the auxiliary rod 2 and the support rod 1 and the pressing disc 19 are in contact with the outside of the warning sign or instruction sign. At this time, the lifting screw rod 22 that moves along with it moves in the lifting groove 17 to carry out the lifting connection work between the movable screw rod 22 and the support rod 1 and the auxiliary rod 2. At the same time, the magnetic strip 23 cooperates with the magnetic sheet 24 to carry out the magnetic pre-positioning work on the screw rod 22 after the lifting movement through the lifting seat 18. Then, rotate the pressing column 20 to cooperate with the thread groove 21 and the screw rod 22 to make the pressing disc 19 carry out the pressing and positioning operation on the warning sign, so that the user can place the warning sign and the instruction sign on the front side of the support rod 1 and the auxiliary rod 2 to carry out the information warning operation on pedestrians. Then, connect the control box 3 to the external power supply through a wire, so that the control box 3 supplies power to the infrared emitter 10, the infrared receiver 11 and the alarm 12 to start. After the infrared emitter 10 is powered on, it emits infrared rays to the infrared receiver 11. The infrared receiver 11 receives the infrared rays emitted by the infrared emitter 10 to form an infrared monitoring band. When an external pedestrian inadvertently interrupts the infrared rays between the infrared emitter 10 and the infrared receiver 11, the infrared receiver 11 transmits the signal to the control box 3. After the control box 3 receives the signal, it starts the buzzer alarm 12 to carry out the audible warning work on the pedestrians outside the warning tape 5.

[0038] It should be noted that the control box 3, the infrared transmitter 10, the infrared receiver 11, and the alarm 12 are all devices or equipment existing in the prior art, or devices or equipment that can be realized by the prior art. Their power supply, specific composition, and principle are clear to those skilled in the art, so they will not be described in detail here.
