Description

Technical Field

[0001] This utility model relates to the technical field of rotational torque detection devices, specifically to a rotational torque detection device for the hydraulic slip ring of a continuous casting machine ladle turret. Background Technology

[0002] The ladle turret is a key piece of equipment in the operation of a continuous casting machine. Most of the equipment on it is hydraulically driven, so the hydraulic slip ring of the ladle turret is particularly important from a functional perspective.

[0003] A hydraulic slip ring is a device used to transfer liquid media. Its working principle is to use the friction between the seal and the rotating contact surface to transfer the liquid media from the fixed part to the rotating part. When the rotating part starts to rotate, the liquid media will enter the hydraulic slip ring through the inlet of the fixed part and flow through the internal grooves to the outlet of the rotating part, thereby realizing the transfer of the power medium.

[0004] If the hydraulic slip ring seal is damaged or the rotary bearing is damaged, the resistance will increase. When the resistance increases to the point that the fork connecting the slip ring and the rotating part breaks, the rotating part of the slip ring will stop rotating. At this point, if the trolley continues to rotate, it will tear all the hydraulic lines, causing a serious equipment accident. Equipment inspection cannot effectively detect the deterioration trend and prevent damage to the hydraulic slip ring. Utility Model Content

[0005] Technical problems to be solved In view of the above-mentioned shortcomings of the existing technology, the present invention provides a hydraulic slip ring rotation torque detection device for the ladle turret of a continuous casting machine, which can effectively solve the problems in the existing technology.

[0006] Technical solution This utility model provides a hydraulic slip ring rotation torque detection device for a continuous casting machine ladle turret, comprising a fixed part, a circular groove in the middle of the fixed part, a hydraulic slip ring placed in the circular groove, a fork sleeved on the outer side of the hydraulic slip ring, side grooves on both sides of the bottom of the fork, a claw and a sensor disposed in the side groove, the sensor disposed on the outer side of the claw, and the top of the sensor contacting and fixed with the top of the side groove, the top of the fork being fixedly connected to a universal bearing, and the output end of the rotating part sleeved in the middle of the universal bearing, and the output end being fixedly connected to the top of the fork.

[0007] Furthermore, multiple sets of positioning rods are fixed on the outer side wall of the hydraulic slip ring, and a locking hole with a size adapted to the positioning rod is opened on the inner side wall of the pawl, and the positioning rod is inserted and fixed into the locking hole.

[0008] Furthermore, the side grooves are symmetrically arranged on both sides of the shift fork, and one end of each of the two sets of sensors is electrically connected to an external PLC control structure.

[0009] Furthermore, circular grooves are provided on the two end side walls of the side groove, and the two sides of the claw are engaged in the circular grooves by protrusions.

[0010] Furthermore, the protrusion and the circular groove are respectively provided on the front side of the pawl and the side groove.

[0011] Beneficial effects In this invention, a combination of protrusions and grooves is used to record the torque during rotation. The pressure between the sensor and the inner groove at the top of the groove is recorded via a rocker-type structure and transmitted to an external PLC via cable. This transmits the data to obtain the specific value of the internal torque. Therefore, this invention can be used on hydraulic slip rings in various sizes of large-scale rotary tables. By selecting a pressure sensor with a suitable measurement range, dynamic real-time detection of the force borne by the hydraulic slip ring during rotation can be achieved. In practical applications, the normal range of torque can be calculated based on the measured values. Based on this data, multiple alarm values ​​for torque changes can be established. Different alarm levels allow for real-time monitoring of the hydraulic slip ring's operating status and effective detection of its deterioration trends. Attached Figure Description

[0016] The present invention will be further described below with reference to the embodiments.

[0017] Example: A device for detecting the rotational torque of the hydraulic slip ring on the ladle turret of a continuous casting machine, as shown in the attached document. Figure 1 -Appendix Figure 5 The device includes a fixed part 1, with a circular groove in the middle of the fixed part 1. A hydraulic slip ring 2 is placed in the circular groove. A shift fork 6 is fitted on the outer side of the hydraulic slip ring 2. Side grooves 61 are formed on both sides of the bottom of the shift fork 6. A pawl 7 and a sensor 3 are arranged in the side grooves 61. The sensor 3 is located on the outer side of the pawl 7, and its top end is in contact with the top end in the side groove 61. The top end of the shift fork 6 is fixedly connected to a universal bearing 5. The output end of the rotating part 4 is fitted in the middle of the universal bearing 5, and its output end is fixedly connected to the top end of the shift fork 6. The device directly transmits rotational torque to the pawl 7 through the cooperation of the shift fork 6 and the positioning rod 21 on the outer side of the hydraulic slip ring 2. The sensor 3 then collects the torque data in real time, avoiding the error of indirect detection. This accurately reflects the true working state of the hydraulic slip ring 2 and provides a reliable basis for fault diagnosis. The claw 7 engages with the circular groove 62 of the side groove 61 through the protrusion 72, ensuring that there is no loosening or offset during the torque transmission process, and reducing the impact of mechanical clearance on the detection.

[0018] Multiple positioning rods 21 are fixed on the outer side wall of the hydraulic slip ring 2. The inner side wall of the claw 7 is provided with a locking hole 71 whose size is adapted to the positioning rod 21. The positioning rod 21 is inserted and fixed into the locking hole 71. The overall structure of the device is compact. The fixed part 1 and the rotating part 4 are connected by a universal bearing 5, which can adapt to the rotation of the hydraulic slip ring 2. There is no need to make major modifications to the original rotary table structure. It can realize online detection and ensure the continuous normal operation of the equipment.

[0019] Sensor 3 is in direct contact with the outside of claw 7, which can sensitively capture changes in torque. Furthermore, the two sets of symmetrically arranged sensors 3 can cancel out lateral force interference through data comparison, further improving detection accuracy.

[0020] The side grooves 61 are symmetrically arranged on both sides of the shift fork 6, and one end of each of the two sets of sensors 3 is electrically connected to the external PLC control structure. Circular grooves 62 are opened on the side walls at both ends of the side grooves 61, and the two sides of the shift claw 7 are engaged in the circular grooves 62 by protrusions 72. The protrusions 72 and the circular grooves 62 are respectively arranged at the front end of the side of the shift claw 7 and the side grooves 61. First, through the combined structure of the protrusions 72 and the circular grooves 62, the torque during rotation is recorded by the sensor 3 and the pressure between the sensor 3 and the inner side groove 61 at the top of the groove through this rocker-type structure, and transmitted to the external PLC structure through the transmission method such as cable, so as to obtain the specific value of the internal torque. Therefore, it can be used on the hydraulic slip ring 2 in the large package rotary table of various specifications. As long as a pressure sensor 3 with a suitable measurement range is selected, the force borne by the hydraulic slip ring 2 during rotation can be dynamically detected in real time. In practical applications, the normal range of torque can be calculated based on measured values. Based on these basic data, multiple alarm values ​​for torque changes can be set. Based on different levels of alarms, the operating status of the hydraulic slip ring 2 can be monitored at any time, and its deterioration trend can be effectively detected.

[0021] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
