Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0022] As Figures 1 - 3 shown, this application provides a sling steel cable weighing sensor, which is mainly installed on the steel cable between the sling of the gantry crane and the reactive grab, and is used to accurately measure the weight of the materials grabbed by the sling. Specifically, the weighing sensor includes a housing 1, and the housing 1 is made of 2Cr13 stainless steel and integrally formed, so as to adapt to harsh working environments such as ports and docks. At the same time, fixing bolt mounting holes are provided at the upper end of the housing 1 for connecting with the sling steel cable; And an elastomer 2 is arranged inside the housing 1. Flanges (not marked in the figure) are provided at the upper and lower ends of the elastomer 2. At the same time, bolt mounting holes are provided at the lower end of the housing 1, and the outer diameter of the bolt mounting holes is slightly smaller than the outer diameter of the upper flange of the elastomer 2, so that the housing 1 and the elastomer 2 are closely fitted. At the same time, a sealing gasket is added between the housing 1 and the elastomer 2 to ensure the sealing performance inside the sensor.

[0023] And the outer diameter of the upper flange of the elastomer 2 is slightly larger than that of the lower flange, so that the elastomer 2 can be smoothly connected to the housing 1; At the same time, both the upper and lower ends of the elastomer 2 are inclined planes, and an antenna emission hole 4 is provided on the lower inclined plane of the elastomer 2 to meet the wireless signal emission requirements of the sensor; And an antenna 9 is arranged at the antenna emission hole 4. In this application, the antenna 9 can be a lightweight, durable and bendable chili stick antenna. At the same time, the gap between the antenna 9 and the antenna emission hole 4 is filled with a 4:1 waterproof glue, and then the antenna emission hole 4 is covered with a 1:1:0.5% polyurethane glue to prevent moisture from entering the sensor and protect the internal components from damage; Meanwhile, a wireless module 5 is fixedly arranged on one side of the power management module 6 at the lower end of the elastomer 2, and a silica gel gasket is arranged between the wireless module 5 and the elastomer 2, so as to achieve the functions of shock absorption and insulation through the silica gel gasket, thereby protecting the wireless module 5 from vibration and electromagnetic interference; Thus, the wireless module 5 emits signals through the antenna 9 arranged at the antenna emission hole 4, and the signals are received by the wireless receiver 10 installed in the cab, so as to realize the communication between the sensor and the cab instrument box. The wireless communication technology provides 116 channels to ensure stable and reliable communication; Meanwhile, a charging hole 3 is arranged on one side of the antenna emission hole 4 on the elastomer 2, and a charging module 11 is fixedly arranged in the charging hole 3. In this application, the charging module 11 can be a Type-C charging module, so as to meet the charging requirements of the sensor. And the charging hole 3 is sealed with a metal plug with a sealing gasket when not charging to prevent dust and moisture from entering; And a battery slot 8 is formed on the elastomer 2, and a battery 7 is arranged inside the battery slot 8. In this application, the battery 7 can be a rechargeable high-rate battery, and a power management module 6 is arranged at the lower end of the elastomer 2 to facilitate the control of the charging, discharging of the battery 7 and the stable output of the power; In practical applications, first, after the wireless weighing sensor is installed in place, the crane and the reactive grab are connected, and the real-time tensile value is calculated in real time to obtain the AD value. The signal is sent to the wireless receiver 10 in the cab through the wireless communication technology. The receiver filters, samples and amplifies the whole data. The grab is suspended in the air. At this time, the read value is the zero value. After grabbing the material, the value read again is the weight of the bulk material in this grab. The values of several times are accumulated to be the total weight of the final bulk material, so as to achieve the actual application of barge weighing.
