[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-5 As shown, a depth detection device for a mining hoist's lifting container includes a main body 1. An adjustment detection device 2 is provided on one side of the main body 1. The adjustment detection device 2 includes a detection component 3 and an adjustment component 4. The detection component 3 includes a sensor main station 21, a lifting movable container 22, and a sensor substation 23. The sensor substation 23 is fixedly installed on the top of the lifting movable container 22, and the detection end of the sensor substation 23 is set upward. It adopts a non-contact distance measuring sensor, and there are no obstructions above the detection end. The sensor main station 21 is fixedly installed on one side of the main body 1 and corresponds to the sensor substation 23 in the vertical direction.

[0025] During operation, sensor substation 23 is fixedly installed on the top of the hoisting mobile container 22, with its detection end facing upwards and unobstructed above it. This minimizes interference from other equipment or obstacles inside the well shaft on the detection signal, ensuring stable transmission of the detection signal. Sensor substation 23 is vertically aligned with sensor substation 22, directly monitoring the vertical displacement of the hoisting mobile container 22, thus improving response speed and reliability.

[0026] Furthermore, the main body 1 includes a fixed pile 11, a first-stage movable arm 12 is movably installed on one side of the fixed pile 11, a first servo motor 13 is fixedly installed on the top of the fixed pile 11, and the output end of the first servo motor 13 is fixedly installed on one side of the first-stage movable arm 12.

[0027] During operation, through the movable installation between the fixed pile 11 and the first-stage movable arm 12, when the first servo motor 13 is driven to run, the output end of the first servo motor 13 drives the first-stage movable arm 12 to rotate. Since the first-stage movable arm 12 is supported and limited by the fixed pile 11, the first-stage movable arm 12 will move axially around the connection point of the fixed pile 11.

[0028] Furthermore, the main body 1 also includes a second servo motor 14, and a second-order movable arm 15 is fixedly installed at the output end of the second servo motor 14. A first-order movable arm 12 is movably installed on one side of the second-order movable arm 15, and the top side of the first-order movable arm 12 is fixedly installed with the second servo motor 14.

[0029] During operation, the second servo motor 14 is used as the power source. When the second servo motor 14 is driven to work, the second-stage movable arm 15 moves axially around the connection point of the first-stage movable arm 12. The mutual cooperation between the second-stage movable arm 15, the first-stage movable arm 12 and the fixed pile 11 realizes the adjustment of the movement of the connecting frame 24.

[0030] Furthermore, the adjusting component 4 includes a connecting frame 24, on the top of the connecting frame 24 are fixedly mounted two guide rails 25, and on the top of the two guide rails 25 are movably mounted two movable wheels 26, wherein the two movable wheels 26 are fixedly mounted on the output end of the stepper motor 27.

[0031] During operation, the connection between the connecting frame 24 and the guide rail 25 limits the four movable wheels 26. When the movable wheels 26 at the output end of the stepper motor 27 rotate, the movable wheels 26 move on the guide rail 25 through the cooperation between the movable wheels 26 and the guide rail 25.

[0032] Furthermore, the adjusting component 4 also includes a movable platform 31, with four movable wheels 26 movably installed at the bottom of the movable platform 31, and a sensor master station 21 fixedly installed at the top of the movable platform 31;

[0033] During operation, when the movable wheel 26 rotates on the guide rail 25, the bottom of the movable platform 31 is supported by the movable wheel 26. At this time, the movable platform 31 will make linear displacement on the connecting frame 24 as the movable wheel 26 rotates, thereby driving the sensor master station 21 at the top to make synchronous movements.

[0034] Furthermore, the adjusting component 4 also includes a torque motor 28 with a self-locking function. The bottom of the torque motor 28 is fixedly installed on the top of the movable platform 31. A winch 29 is fixedly installed at the output end of the torque motor 28. A lifting movable container 22 is fixedly installed at the output end of the winch 29.

[0035] During operation, the torque motor 28 drives the winch 29 to rotate, thereby lifting or lowering the movable container 22. The torque motor 28 with self-locking function can automatically lock after the movable container 22 reaches the designated position to prevent it from sliding due to gravity or other external forces, thus ensuring the stability and safety of the detection process.

[0036] Working principle: The first servo motor 13 and the second servo motor 14 drive the first-order movable arm 12 and the second-order movable arm 15 to rotate, adjusting the position of the connecting frame 24. At the same time, the stepper motor 27 drives the movable wheel 26 to move on the guide rail 25, so that the movable platform 31 drives the sensor master station 21 to move precisely in the horizontal direction, ensuring that the sensor master station 21 and the sensor sub-station 23 correspond in the vertical direction. When the hoisting movable container 22 moves up and down with the rotation of the winch 29, the sensor sub-station 23 moves synchronously with it. The sensor master station 21 senses the position change of the sensor sub-station 23 in real time and transmits the signal to the processing system. By calculating the vertical displacement of the sensor sub-station 23, the depth information of the hoisting movable container 22 is obtained. In the whole process, there are no obstructions above the detection end of the sensor sub-station 23, which reduces the interference of the detection signal and ensures the accuracy and reliability of the detection. At the same time, the cooperation of each power component realizes the flexible adjustment of the position of the detection device to adapt to different mine hoisting conditions.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
