[0002] The maintenance personnel of the utility poles and towers generally report that when the hooks of the flat ladders distributed now are often used to hang the wires, because the angles formed by the end of the flat ladders and the lines are different due to different tower shapes, the angle of the flat ladder hooks needs to be adjusted according to the actual situation on site. In the case where the angle of the hook has already been set for the flat ladder, it is easy to encounter the wire due to shaking, etc., so that the angle of the hook changes and the hook cannot be hung on the wire smoothly, which increases the work intensity and time, and increases the workload of the operator. Unsafe factors greatly reduce work efficiency

The invention provides a flat ladder hanging hook direction adjusting locking device. The flat ladder hanging hook direction adjusting locking device comprises a triangle bracket, a hanging hook, a disk, and a flat ladder. The triangle bracket comprises two bracket legs in a reversed V-shape, a horizontal tray which is in contact with the upper parts of the two bracket legs, and two bolt holes with the same size which are respectively installed the tail ends of the two bracket legs. The middle of the tray is provided with a hanging hook hole. The bolt holes are respectively used for connectingthe flat ladder. The hanging hook vertically passes through a center of the disk and is fixed to the disk. A diameter of the disk is greater than a diameter of the hanging hook hole in the tray. Thehanging hook fixed to the disk is placed on the tray. The hanging hook passes through the hanging hook hole in the tray. The lower part of the hanging hook is fixed to a nut through a hard cushion sheet. A diameter of the hard cushion sheet is greater than a hole diameter of the hanging hook hole. The flat ladder hanging hook direction adjusting locking device provided by the invention can be usedfor effectively preventing a hanging hook direction from being changed while the flat ladder is moved and installed.
Description
technical field [0001] The invention relates to the field of mechanical equipment, in particular to a locking device for adjusting the direction of a hook of a flat ladder. Background technique [0002] The maintenance personnel of the utility poles and towers generally report that when the hooks of the flat ladders distributed now are often used to hang the wires, because the angles formed by the end of the flat ladders and the lines are different due to different tower shapes, the angle of the flat ladder hooks needs to be adjusted according to the actual situation on site. In the case where the angle of the hook has already been set for the flat ladder, it is easy to encounter the wire due to shaking, etc., so that the angle of the hook changes and the hook cannot be hung on the wire smoothly, which increases the work intensity and time, and increases the workload of the operator. Unsafe factors greatly reduce work efficiency. Contents of the invention [0003] In orde...
