[0020] A special self-locking anti-collision tensioning device for a stacker reclaimer jib, referring to the drawings Figure 1 - the drawings Figure 4 As shown in the drawings, it comprises a plurality of sets of tensioning device bodies arranged along the length direction of the reclaimer cantilever 1, each set of tensioning device body comprising two tensioning device bodies 2 arranged on the left and right sides of the reclaimer cantilever; the tensioning device body 2 comprises a tension spring plate 3, a tension spring 4, a steel wire rope support 5 and a fixed support 6, the tension spring plate 3 and the fixed support 6 are both fixedly installed on the side wall of the reclaimer cantilever 1, and the fixed support 6 is located below the tension spring plate 3; the steel wire rope support 5 comprises a hinged rod 5.1 hinged with the fixed support 6; one end of the hinged rod 5.1 is hinged with the fixed support 6. Specifically, the hinged rod 5.1 is provided with a hinge shaft 5.5, and the fixed support 6 is provided with a hinge hole matched with the hinge shaft 5.5, and the hinged rod 5.1 is hinged on the fixed support 6 through the hinge shaft 5.5 and the hinge hole.
[0021] The other end of the hinged rod 5.1 is fixed with a steel wire rope sleeve 5.2, the outer wall of the steel wire rope sleeve 5.2 is respectively connected with a pull ear 5.3 and a pull plate 5.4, the two ends of the tension spring 4 are respectively connected with the pull ear 5.3 and the tension spring plate 3, and when the tension spring 4 is in a relaxed state, the hinged rod 5.1 is in an inclined downward posture; as a preferred, the pull plate 5.4 is in a horizontal position when the tension spring is in a relaxed state, the included angle between the hinged rod 5.1 and the pull plate 5.4 is 30-35°, and the included angle between the pull ear 5.3 and the pull plate 5.4 is 60-65°
[0022] The steel wire rope sleeve 5.2 is sleeved with a pull rope 7, one end of the pull rope 7 is fixed to one end of the reclaimer cantilever 1, and the other end of the pull rope 7 is connected with a pull rope switch 8 fixedly installed at the other end of the reclaimer cantilever 1; the pull plates 5.4 of each set of tensioning device body 2 are connected through a steel wire rope 9. Specifically, the pull plate 5.4 comprises two pull plates 5.4 fixedly installed on the outer wall of the steel wire rope sleeve 5.2, a pin shaft 10 is sleeved between the two pull plates 5.4, and the steel wire rope 9 is fixedly connected on the pin shaft 10.
[0023] The present application is applied to the application scene, and the drawings Figure 2As shown, when the reclaimer cantilever 1 touches the coal pile and is about to collide with the coal pile during transmission, the steel wire rope support 5 first contacts the coal pile, at this time, the hinged rod 5.1 overcomes the elastic force of the tension spring 4 and rotates clockwise along the hinge point with the fixed support 6, the hinged rod 5.1 pulls the pull rope 7 sleeved in the steel wire rope sleeve 5.2 during the rotation, the pull rope triggers the pull rope switch 8 during being pulled, the pull rope switch 8 is closed, thereby the reclaimer cantilever 1 is braked in an emergency during the rotation, so as to avoid the collision between the reclaimer cantilever 1 and the coal pile, prevent the collision from damaging the bucket wheel hydraulic station platform and the anti-collision support of the cantilever.
