Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and in particular to a rainproof system and method for a busbar of a bridge crane. Background Art

[0002] In the production of large metallurgical plants, bridge cranes are installed in the factory buildings. As "air carriers", bridge cranes can efficiently carry, accurately position and safely load and unload large and heavy materials by moving and lifting in three-dimensional space. The busbars of bridge cranes are high-voltage busbars. Once the factory building is old and not repaired in time, and once the roof of the factory building leaks but is not discovered in time, the raindrops will fall on the crane busbars, which can easily cause a short circuit in the busbars and cause safety problems.

[0003] In the prior art, it is usually necessary to wait until it is obvious that there is a leak on the roof of the factory building or a certain amount of rainwater has accumulated on the busbar of the bridge crane before the staff can pay attention to it and repair the leak on the roof of the factory building to prevent the rainwater from falling on the busbar and causing a safety accident. This method is highly dependent on the staff and cannot quickly and effectively locate the leak, which is not conducive to improving the efficiency of preventing rainwater from falling on the busbar of the bridge crane, and is prone to safety accidents due to untimely response.

[0004] Based on this, the existing technology is in urgent need of improvement. Summary of the invention

The present invention provides a rainproof system and method for the busbar of a bridge crane.

[0006] According to a first aspect of the present invention, a rain protection system for a busbar of a bridge crane is provided, comprising: A guide rail, both ends of which are connected to the pillars of the plant and are located at a preset distance above the busbar of the bridge crane; A running mechanism movably mounted on the guide rail, wherein the running mechanism has a built-in driving unit and a rain shield is mounted on the top, and the rain shield can be opened or closed under the drive of the running mechanism; A plurality of humidity sensors installed on the guide rail and evenly distributed, the humidity sensors being used to detect the humidity value at the current position; A controller installed on the operating mechanism and communicatively connected to the drive unit and the plurality of humidity sensors, the controller being configured to calculate the distance value between the operating mechanism and the sensors with humidity values greater than the threshold and send a start signal to the drive unit based thereon, so that the operating mechanism moves the distance value and unfolds the rain shield to prevent rain from falling on the sliding contact line.

[0007] In some embodiments, the rain shield is an inclined deflector that can be unfolded downward.

[0008] In some embodiments, the inclination direction of the inclined deflector is different from the direction of the sliding contact line.

[0010] In some embodiments, the speed reducer is a three-in-one speed reducer integrating a motor, a speed reducer and a brake.

[0011] In some embodiments, the number of the guide wheels is 4 and the guide wheels are connected to the guide rail.

[0012] In some embodiments, a plurality of water immersion sensors are further included, and the water immersion sensors are installed on the inner side of the factory building roof and are in the same vertical direction as the humidity sensors.

[0013] In some embodiments, the water immersion sensors are communicatively connected to the controller, and the water immersion sensors are configured to detect whether there is water on the inner side of the factory building roof corresponding to the positions of the humidity sensors and send the detection results to the controller, so that the controller obtains the rain leakage positions of the factory building roof.

[0014] In some embodiments, the operating mechanism is installed on the guide rail through a cable to be movable on the guide rail.

[0015] According to a second aspect of the present invention, there is provided a method for preventing rain on a sliding contact line of a bridge crane, using the bridge crane sliding contact line rain prevention system as described in any one of the above, the method including: In response to the controller receiving the humidity value transmitted back by the humidity sensor, compare it with the threshold value, obtain the location of the sensor where the humidity value is greater than the threshold value, and calculate the distance value between it and the operating mechanism; Based on the distance value, the controller sends a start signal to the drive unit of the operating mechanism, and through the drive unit, the operating mechanism moves the distance value and unfolds the rain shield to prevent rain from falling on the crane trolley wire.

[0016] The above-mentioned rain-proof system for the trolley wire of a bridge crane includes a guide rail, a movable operating mechanism installed on the guide rail, a plurality of humidity sensors installed on the guide rail and evenly distributed, the operating mechanism has a built-in drive unit and a rain shield is installed on the top, and the rain shield can be unfolded or closed under the drive of the operating mechanism.

Although only a few embodiments of the present invention are described in detail, those skilled in the art can easily appreciate that various modifications are feasible without substantially departing from the teachings of the subject matter of the present invention. Accordingly, all such modifications should be included within the scope of the present invention. Without departing from the gist of the present invention, other substitutions, modifications, variations, and deletions can be made to the design, operating conditions, parameters, etc. of the following exemplary embodiments.

[0027] According to a first aspect of the present invention, the present invention provides a rainproof system for a trolley wire of a bridge crane. Please refer to Figure 1-2 , Figure 1 which is the front view of the rainproof system for the trolley wire of the bridge crane. Figure 2It is a side view of the rainproof system for the trolley wire of a bridge crane. The rainproof system for the trolley wire of a bridge crane includes a guide rail 1, the two ends of the guide rail 1 are connected to the two ends of the factory building column 2, and the guide rail 1 is located at a position with a preset distance above the trolley wire 4 of the bridge crane 3. For example, the guide rail 1 is within the range of 0.5 to 1 m above the trolley wire 4 of the bridge crane 3. The factory building roof 12, the guide rail 1 and the trolley wire 4 of the bridge crane 3 form a vertical shielding relationship in the vertical direction. The rainproof system for the trolley wire of a bridge crane further includes a running mechanism 5 installed on the guide rail 1. The running mechanism 5 can move on the guide rail 1. The running mechanism 5 is internally provided with a driving unit 6 and a rain shield 7 is installed on the top of the running mechanism 5. The rain shield 7 can be opened or closed under the drive of the running mechanism 5. Optionally, as Figure 1 shown, the running mechanism 5 is installed on the guide rail 1 through a cable 10 to enable the running mechanism 5 to move on the guide rail 1. Optionally, the rain shield 7 is an inclined deflector that can be unfolded downward. The downward inclined deflector can cause the rainwater 11 falling on it to fall quickly, avoiding the accumulation of rainwater 11 on the rain shield 7, thereby avoiding the problem of water accumulation on the rain shield 7 and facilitating the quick fall of the rainwater 11. Further, the inclined direction of the inclined deflector is different from the direction of the trolley wire 4, so as to avoid the rainwater from falling onto the trolley wire 4 of the bridge crane 3 again. The rainproof system for the trolley wire of a bridge crane further includes a plurality of humidity sensors 8 installed on the guide rail 1. They are evenly distributed and used to detect the humidity value at their respective positions. Since the factory building roof 12, the guide rail 1 and the trolley wire 4 of the bridge crane 3 form a vertical shielding relationship in the vertical direction, therefore, if there is a rain leakage point in the vertical direction of the position where a certain humidity sensor 8 is located, the rainwater 11 leaking from the rain leakage point of the factory building roof 12 will first fall on the guide rail 1. At this time, the humidity sensor 8 at the corresponding position on the guide rail 1 can measure a humidity value higher than the threshold. The rainproof system for the trolley wire of a bridge crane further includes a controller 9 installed on the running mechanism 5. The controller 9 is respectively communicatively connected to the driving unit 6 of the running mechanism 5 and the humidity sensors 8. The controller 9 is used to receive the humidity values transmitted back by each humidity sensor, compare them with a preset humidity threshold, obtain the humidity sensors 8 with humidity values greater than the preset threshold, and start rainproof measures at their respective positions, calculate the distance value between the humidity sensor 8 and the running mechanism 5, and send a start signal to the driving unit 6 built in the running mechanism 5 based on the distance value. The driving unit 6 drives the running mechanism 5 to start and move this distance value and then reach the target position (that is, the position where the humidity sensor 8 is located) based on the received start signal. At the same time, the running mechanism 5 drives the rain shield 7 to unfold under the drive of the driving unit 6, effectively preventing the rainwater 11 from falling onto the trolley wire 4.

[0028] The above rain-proof system for the trolley wire of a bridge crane reduces the dependence on staff during the process of realizing rain protection for the trolley wire 4 of the bridge crane 3 through the mutual cooperation and communication interaction among the guide rail 1, the running mechanism 5 and its built-in drive unit 6, the humidity sensor 8, and the rain shield 7. When there are rain leakage points on the factory building roof 12, it improves the efficiency of effectively detecting the positions of the rain leakage points and automatically takes corresponding measures in a timely manner, reducing the problem of safety accidents caused by untimely response.

[0029] According to several embodiments of the present invention, on the basis of Figure 1-2 , with reference to Figure 3 , Figure 3 FIG. 9 is a front view of the rain-proof system for the trolley wire of a bridge crane provided by another embodiment of the present invention. The rain-proof system for the trolley wire of a bridge crane further includes a plurality of water immersion sensors 18. The water immersion sensors 18 are arranged on the inner side of the factory building roof 12, and the water immersion sensors 18 and the humidity sensors 8 are in the same vertical direction. The water immersion sensors 18 are used to detect whether there is water at their positions. The water immersion sensors 18 are communicatively connected to the controller 9, and the water immersion sensors 18 transmit their detection results back to the controller 9. The controller 9 can comprehensively analyze the humidity values transmitted back by the humidity sensors 8 and the detection results of the water immersion sensors 18 in the same vertical direction as them, avoiding the problem of errors in locating the rain leakage positions on the factory building roof 12 relying only on the humidity values transmitted back by the humidity sensors. For example, if the humidity value transmitted back by a certain humidity sensor 8 received by the controller 9 is greater than the threshold value, it can be preliminarily determined that the position on the factory building roof 12 corresponding to the vertical direction of the humidity sensor 8 may be a rain leakage position. If at the same time, the detection result of the water immersion sensor 18 corresponding to the vertical direction of the humidity sensor 8 is that there is water, then the position on the factory building roof 12 corresponding to the vertical direction of the humidity sensor 8 can be located as the position of the rain leakage point. By verifying the accuracy of the detection results of the corresponding humidity sensors 8 through the detection results of the water immersion sensors 18, the accuracy of locating the rain leakage point positions is greatly improved.

[0030] According to several embodiments of the present invention, on the basis of Figure 1-2 , with reference to Figure 4-5 , Figure 4 FIG. 18 is a front view of the running mechanism. Figure 5It is a side view of the running mechanism. The running mechanism 5 includes a main body frame 13, a speed reducer 14, a driving wheel 16, a transmission gear 15 and a guide wheel 17. Among them, the main body frame 13 is installed on the guide rail 1, the speed reducer 14 is installed on the lateral support platform of the main body frame 13, the driving wheel 16 is located inside the main body frame 13 and is connected to the guide rail 1, the transmission gear 15 is between the output end of the speed reducer 14 and the shaft of the driving wheel 16, and the guide wheel 17 is located inside the main body frame 13 and is installed at the front and rear ends of the driving wheel 16. The structure of the running mechanism 5 ensures the stability of the running mechanism 5 during the movement on the guide rail 1, so as to ensure that the rain shield 7 is always in a stable state during the movement of the running mechanism 5, and problems such as looseness will not occur.

[0031] Furthermore, the speed reducer 14 is a three-in-one speed reducer integrating a motor, a speed reducer and a brake. The three-in-one speed reducer optimizes space and efficiency through integrated design and is suitable for precision automation scenarios.

[0032] Furthermore, the number of the guide wheels 17 is 4 and the guide wheels 17 are connected to the guide rail 1. The guide wheels 17 are installed at the front and rear ends of the driving wheel 16, with 2 respectively, ensuring the smooth operation of the running mechanism 5 on the guide rail 1.

[0033] According to the second aspect of the present invention, the present invention also provides a method for preventing rain on the trolley wire of a bridge crane, as Figure 6 shown, using the trolley wire rainproof system described in any one of the above, the method includes: Step a: In response to the humidity value returned by the humidity sensor received by the controller, compare it with the threshold value, obtain the position of the sensor where the humidity value is greater than the threshold value, and calculate the distance value between it and the running mechanism; Step b: The controller sends a start signal to the drive unit of the running mechanism based on the distance value, and the running mechanism moves the distance value and unfolds the rain shield through the drive unit to prevent rain from falling on the trolley wire of the crane.
