Furthermore, the terms "first," "second," and "third" as appearing herein are used for descriptive purposes only and are not to be construed as indicating or implying relative importance
As shown in fig. 1 to 4, the steel wire rope connecting device for the equipment train comprises a C-shaped joint main body 1, wherein the joint main body 1 is provided with a through hole penetrating through the top and the bottom, a pin cylinder 2 coinciding with the axis of the through hole is fixed at the top of the joint main body 1, and a tooth-shaped sleeve 3 concentric with the pin cylinder is fixed inside the pin cylinder 2. The bottom of the tooth-shaped sleeve 3 is uniformly provided with four wedge-shaped chutes 3.1 and half-tooth-shaped gaps 3.2 with the same number, and the wedge-shaped chutes 3.1 and the half-tooth-shaped gaps 3.2 are arranged adjacent to each other; a push rod 4 and a connecting pin 5 are inserted in the tooth-shaped sleeve 3 in a sliding manner, and a sliding block 4.1 which slides in the wedge-shaped sliding groove 3.1 is fixed on the outer wall of the push rod 4, so that the push rod 4 can only slide in the pin cylinder 2 along the axial direction and cannot rotate. Tooth-shaped notches 4.2 are uniformly distributed at the bottom of the push rod 4 in the circumferential direction, and the tooth-shaped notches 4.2 and the half-tooth-shaped notches 3.2 are arranged in a staggered mode; the connecting pin 5 is divided into an upper section and a lower section, the diameter of the upper section is larger than that of the lower section, a half-tooth-shaped sliding block 5.1 capable of being meshed with the tooth-shaped notch 4.1 is fixed on the outer wall of the upper section of the connecting pin 5, and when the half-tooth-shaped sliding block 5.1 is positioned in the wedge-shaped sliding chute 3.1 or the half-tooth-shaped notch 3.2, the half-tooth-shaped sliding block 5.1 cannot be completely meshed with the tooth-shaped notch 4.2; when the push rod 4 drives the connecting pin 5 to move downwards, once the half-tooth-shaped sliding block 5.1 is separated from the wedge-shaped sliding groove 3.1 or the half-tooth-shaped notch 3.2, the half-tooth-shaped sliding block 5.1 rotates for a certain angle under the action of the extrusion force and is completely meshed with the tooth-shaped notch 4.2. The lower section of the connecting pin 5 is sleeved with a spring 6, and the outer diameter of the spring 6 is smaller than the inner diameter of the tooth-shaped sleeve 3. When the downward movement is stopped, the reset force of the spring 6 can push the connecting pin 5 to move upwards, so that the half-tooth-shaped sliding block 5.1 enters the adjacent half-tooth-shaped notch 3.2 or the wedge-shaped sliding groove 3.1.
