A connector 7 is fixedly installed on the lower surface of the weight indicator 5. The connector 7 is fixedly connected to the control box 6 through a connecting line 8. A connector 10 is fixedly connected to the lower surface of the connector 7. A cable 11 for connecting to a weighing sensor signal is fixedly connected to the lower surface of the connector 10. The lower end of the cable 11 extends to the outside of the second shell 2. A fixing mechanism 12 is arranged on the bottom wall of the second shell 2. A dustproof mechanism 13 is arranged on the front sides of the first shell 1 and the second shell 2.

[0025] In the present application, the weight indicator 5 has a night vision function, which is convenient for reading the numbers on the weight indicator 5 even in low light conditions, thereby improving the functionality of the weight indicator 5. When in use, the weighing sensor is first connected to the wellhead-related equipment, and then the wellhead gravity obtained by the weighing sensor is converted into an electrical signal through the control box 6. Then, under the action of the cable 11, the electrical signal is transmitted to the weight indicator 5, so that the weight change of the wellhead can be detected on the weight indicator 5, thereby obtaining the weight change of the wellhead, helping the drillers to adjust and control the working state of the drilling rig. For example, during the drilling process, the weight change of the wellhead can indicate whether it is necessary to increase or decrease the weight of the drilling tool to maintain the stability and efficiency of the drilling.

[0026] Furthermore, the upper and lower ends of the first shell 1 and the second shell 2 are fixedly connected with hanging ears 3, and the two upper hanging ears 3 are used to hang the first shell 1 and the second shell 2.

[0033] Furthermore, when in use, first insert the conical nut 1201 into the wire hole 201, then fix the flange 1203 to the second shell 2 by fixing bolts, then insert the cable 11 into the rubber ring 1202, and finally lock the conical nut 1201 by the locking nut 1204 to fix the cable.
