[0003] In construction, when installing electromechanical equipment at high locations, engineering ladders are one of the commonly used auxiliary tools. However, due to the design and use conditions of engineering ladders, it is not convenient to transport tools on engineering ladders, and workers need to carry them up by themselves, which is not only time-consuming and labor-intensive, but also poses certain safety hazards. Specifically, when using engineering ladders, workers need to carry tools and equipment on their backs, and then climb the steps to reach high locations for installation work. This method not only increases the labor intensity of the workers, but also is prone to accidents during the climbing process, leading to safety accidents. In order to address this problem, an engineering ladder for installing electromechanical equipment for construction is proposed. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-7 , an engineering ladder for installing mechanical and electrical equipment for construction, two rotating frames 2 are rotatably installed on a fixed frame 1 through an upper rotating shaft 11, hidden grooves 3 are provided at both ends of the fixed frame 1, two plug rods 12 are slidably penetrated in the hidden grooves 3 through an elastic mechanism, a slot 13 is provided on the rotating frame 2, a dragging frame 4 connected to the two plug rods 12, a storage channel 5 is provided on the fixed frame 1, an equipment room 15 is provided inside the fixed frame 1, a screw rod 17 is rotatably provided in the storage channel 5, a power mechanism connected to the screw rod 17 is provided in the equipment room 15, a movable frame 19 is threadedly sleeved on the screw 17, a movable plate 6 is provided in the storage channel 5, a connecting groove 20 corresponding to the branch of the movable frame 19 is provided on the movable plate 6, a folding groove 7 is provided on the movable plate 6, and a folding plate 9 is rotatably installed in the folding groove 7 through a lower rotating shaft 8 and a torsion spring 10.

[0025] The elastic mechanism includes a return spring 14 sleeved on the outside of the insertion rod 12, and the two ends of the return spring 14 are elastically connected to the inner wall of the hidden groove 3 and the outer wall of the dragging frame 4 respectively. The elastic potential energy provided by the return spring 14 realizes the dragging of the dragging frame 4, ensuring that the insertion rod 12 can be stably located in the slot 13.

[0026] The power mechanism includes a drive motor 16 installed in the equipment room 15 . The output shaft of the drive motor 16 is fixedly connected to the end of the screw 17 . The drive motor 16 is a power device that can realize the rotation of the screw 17 .

[0027] Two stabilizing rods 18 are provided in the storage channel 5 . Both stabilizing rods 18 slide through the movable frame 19 . The stabilizing rods 18 limit the movable frame 19 to prevent it from rotating together with the screw rod 17 .

[0028] The connecting groove 20 is T-shaped in vertical section, and the movable frame 19 in the connecting groove 20 is also T-shaped in vertical section. This situation prevents the movable plate 6 from being separated from the movable frame 19.

[0029] The vertical cross-section of the rod 12 is a regular hexagon, and the vertical cross-section of the slot 13 is also a regular hexagon. After the rod 12 enters the slot 13, the rotating frame 2 cannot rotate relative to the fixed frame 1, and the two rotating frames 2 form a herringbone to form an engineering ladder.

[0030] When the utility model is used, the dragging frame 4 is pulled to drive the insertion rod 12 to move and disengage from the slot 13, and then the rotating frame 2 is rotated to form a Figure 1 In the state shown, the drag frame 4 is immediately released, and the insertion rod 12 is reset and inserted into the slot 13 under the action of the reset spring 14, forming a limit for the rotating frame 2, and then the movable plate 6 is moved out of the storage channel 5. At this time, the folding plate 9 loses the extrusion limit of the inner wall of the storage channel 5, and rotates under the action of the torsion spring 10, from a vertical state to a horizontal state. At this time, the movable plate 6 is combined with the folding plate 9 to form a storage platform, on which electromechanical equipment can be placed. After starting the drive motor 16, the screw 17 can be driven to rotate. When the screw 17 rotates, the movable frame 19 rises, and the movable plate 6 and other components are cooperated to realize the rising of the electromechanical equipment, so that the operator on the rotating frame 2 or the fixed frame 1 can conveniently take the electromechanical equipment.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
