[0026] For easy understanding, please refer to Figures 1 to 3The embodiment provides a support hanger for a fire-fighting ventilation pipeline, which comprises a U-shaped hanger body 1, the hanger body 1 comprises a horizontal rod 2 arranged horizontally and two vertical rods 3 arranged vertically, the left and right sides of the horizontal rod 2 are fixedly connected with the two vertical rods 3 respectively, and the middle part of the hanger body 1 is provided with a ventilation pipeline 4. Two outer cylinders 5 are slidably connected to the horizontal rod 2 of the hanger body 1 in the horizontal direction, and the two outer cylinders 5 are located on the two sides of the ventilation pipeline 4 respectively. The outer cylinder 5 is internally provided with a sliding arm 6 and an upper pressing arm 7, the sliding arm 6 is slidably connected with the outer cylinder 5 in the vertical direction, the sliding arm 6 is internally provided with a vertical sliding rail 8, a pulley 9 is slidably connected to the sliding rail 8, and the sliding arm 6 is slidably connected with the pulley 9 in the vertical direction through the sliding rail 8. The pulley 9 is rotatably connected with the end of one side of the upper pressing arm 7, that is, the upper pressing arm 7 can rotate with the center of the pulley 9 as the center. The two upper pressing arms 7 are detachably connected above the ventilation pipeline 4.
[0027] Since the pulley 9 is slidably connected with the sliding arm 6 in the vertical direction, and the pulley 9 is rotatably connected with the end of the upper pressing arm 7, in the initial state, the upper pressing arm 7 and the sliding arm 6 are both folded and accommodated in the outer cylinder 5; when it is needed to limit the ventilation pipeline 4 in the horizontal direction, the left and right outer cylinders 5 are slid inward respectively until the side walls of the two outer cylinders 5 abut against the left and right side walls of the ventilation pipeline 4, that is, the limitation of the ventilation pipeline 4 in the horizontal direction is completed; when it is needed to limit the ventilation pipeline 4 in the vertical direction, the upper pressing arm 7 is pulled upward, at this time, the pulley 9 is forced to slide in the outer cylinder 5 from bottom to top until the upper pressing arm 7 and the pulley 9 are completely exposed from the outer cylinder 5, then the upper pressing arm 7 is rotated inward with the center of the pulley 9 as the center, so that the bottom surface of the upper pressing arm 7 abuts against the upper wall of the ventilation pipeline 4 on the inner side, when the bottom surfaces of the left and right upper pressing arms 7 abut against the upper walls of the ventilation pipeline 4 on the inner side respectively, the two upper pressing arms 7 are relatively fixed above the ventilation pipeline 4, that is, the limitation of the ventilation pipeline 4 in the vertical direction is completed. When it is needed to accommodate the upper pressing arm 7 and the sliding arm 6 in the outer cylinder 5, first, the upper pressing arm 7 is rotated to be parallel to the sliding arm 6, then the upper pressing arm 7 is pressed downward, at this time, the pulley 9 is forced to slide downward along the sliding rail 8 to the lower end of the sliding rail 8, that is, the upper pressing arm 7 can be accommodated in the outer cylinder 5.
[0028] For the convenience of understanding, please continue to refer to Figures 1 to 3The end of the upper pressing arm 7 connected with the pulley 9 is provided with a through hole 12, and a long circular hole 13 is arranged in the middle of the upper pressing arm 7. The through hole 12 of the first upper pressing arm 7 and the long circular hole 13 of the second upper pressing arm 7 are sequentially penetrated by a bolt, and then are screwed with a nut to realize the relative fixation of the two upper pressing arms 7. The long circular hole 13 can make the hanger body 1 suitable for various ventilation pipes 4 with different outer widths. The two upper pressing arms 7 can be relatively fixed by the cooperation of the bolt and the nut, so as to limit the ventilation pipe 4 in the vertical direction. Further, the inner wall of the long circular hole 13 is provided with a wave-shaped structure corresponding to the rod of the bolt, which further ensures the fixing effect of the two upper pressing arms 7.
[0029] For the sake of understanding, please continue to refer to Figures 1 to 3 The sliding arm 6 is slidably connected with the outer cylinder 5 in the vertical direction. The outer cylinder 5 is provided with a spring 10 movably arranged in the vertical direction. One end of the spring 10 is connected with the inner bottom wall of the outer cylinder 5, and the other end is connected with the bottom of the sliding arm 6. The sliding arm 6 slidably connected with the outer cylinder 5 can make the hanger body 1 suitable for various ventilation pipes 4 with different heights. When the upper pressing arm 7 is pulled upward until the upper pressing arm 7 and the pulley 9 are completely exposed from the outer cylinder 5, the upper pressing arm 7 is continuously pulled upward. At this time, the sliding arm 6 is forced to slide upward in the outer cylinder 5, and the spring 10 is stretched. When the bottom wall of the upper pressing arm 7 abuts against the upper wall of the ventilation pipe 4, the two upper pressing arms 7 are fixed by the bolt, and the ventilation pipe 4 is limited in the vertical direction. The spring 10 can provide downward force to the upper pressing arm 7, so that the bottom surface of the upper pressing arm 7 can be tightly attached to the upper wall of the ventilation pipe 4, and the limiting effect of the upper pressing arm 7 on the ventilation pipe 4 is further improved.
[0030] For the sake of understanding, please refer to Figures 1 to 4The lower part of the outer cylinder 5 is provided with a driving mechanism for driving the two outer cylinders 5 to slide inwards or outwards in the horizontal direction simultaneously, which comprises a bidirectional screw rod 14 having reverse threads at both ends, a connecting plate 15 is threadedly connected to each end of the bidirectional screw rod 14, and the two outer cylinders 5 are fixed above the left and right connecting plates 15 respectively. The two ends of the bidirectional screw rod 14 are rotatably connected to the cross rod 2, and one end extends through the cross rod 2 after being rotatably connected to the cross rod 2, and a rotating handle 16 is connected to the outside of the cross rod 2. By rotating the rotating handle 16 on the outside of the cross rod 2, the bidirectional screw rod 14 connected to the rotating handle 16 can be driven to rotate, and when the bidirectional screw rod 14 rotates, the two outer cylinders 5 on both sides move inwards or outwards simultaneously. By arranging the bidirectional screw rod 14, the hanger body 1 can be suitable for various ventilation ducts 4 with different outer widths, and the sidewalls of the two outer cylinders 5 can be in contact with the sidewalls of the ventilation ducts 4 to limit the ventilation ducts 4 in the horizontal direction. The two vertical rods 3 are provided with grooves 11 corresponding to the horizontal positions of the outer cylinders 5, which can be used for the outer cylinders 5 to enter. When it is necessary to disassemble and transport the hanger body 1, the left and right outer cylinders 5 can be hidden and stored in the two vertical rods 3 respectively, which is convenient for the workers to move and transport the hanger body 1 and reduces the occupied space of the hanger body 1. Further, in the actual production process, the bidirectional screw rod 14 can be designed to be hidden in the cross rod 2, so as to avoid the influence of other external factors on the rotation process of the bidirectional screw rod 14.
