[0003] However, the existing installation ladders for electromechanical engineering do not provide adequate protection for personnel when climbing. For example, a mechanical and electrical engineering installation ladder disclosed in Chinese patent publication number "CN209621181U" cannot fix the safety rope on the ladder when climbing, which creates a safety hazard of falling for personnel working on the ladder. In addition, since it does not have a special tool storage device, it increases the risk of being hit by people under the ladder. Accordingly, the present application proposes an installation ladder for electromechanical engineering. Utility Model Content

DETAILED DESCRIPTION

[0024] 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.

[0025] Reference Figure 1-8 , including a platform 2, a tool box 1 is fixedly connected to the top of the platform 2, four support grooves 12 are provided on the bottom surface of the platform 2, a limit axis 4 is fixedly connected to the center of each support groove 12, a limit bearing 3 is rotatably connected to each limit axis 4, a ladder bracket 9 is fixedly connected to the limit bearing 3, a safety rail 18 is fixedly connected to the ladder bracket 9, a safety belt buckle 25 is slidably connected to the safety rail 18, a slide groove 10 is provided on the ladder bracket 9, a threaded hole 7 is provided above the slide groove 10, a limit hole 8 is provided below the slide groove 10, a support rod 5 is slidably connected in the slide groove 10, and the ladder bracket The lower end of the frame 9 is fixedly connected with an anti-skid base 6, and a plurality of safety limit blocks 20 are fixedly connected inside the ladder bracket. A limit slot 21 is provided on the safety limit block 20, and a square hole 24 is provided on the bottom surface of the limit slot 21. A rotating shaft 22 is rotatably connected to the center of the side wall of the limit slot 21, and a stopper 19 is fixedly connected to the rotating shaft 22. One end of a spring 23 is fixedly connected to the bottom of the square hole 24, and the other end of the spring 23 is fixedly connected to the bottom surface of the stopper 19. Therefore, a plurality of evenly distributed protruding blocks 13 are fixedly connected to the ladder bracket 9, and one end of the stopper 19 away from the rotating shaft 22 is attached to the protruding block 13. It should be noted that before climbing, it is necessary to ensure that the support rod 5 is fixed in the slide slot 10 by the screw 16.

[0026] The surface of the limit bearing 3 is fitted on the inner wall of the support groove 12, a screw 16 is threadedly connected in the threaded hole 7, a pin 17 is rotatably connected in the limit hole 8, a support block 15 is fixedly connected to the pin 17, and one end of the support block 15 away from the limit hole 8 is threadedly connected to the screw 16. It should be noted that the anti-skid material on the surface of the anti-skid base 6 must have a certain ability to resist oil stains.

[0027] When using the device, first unfold the ladder bracket 9, then slide the support rod 5 into the slide groove 10 and tighten it with the screw 16. At this time, the installation ladder structure is supported by the support rod 5, but a safety rope needs to be worn before climbing. When climbing, the safety belt buckle 25 is clamped on the safety guide rail 18. At this time, the support block 19 will be buckled and pushed upward, and the block 19 can be rotated upward within a certain angle, but cannot be rotated downward. When it is rotated to a certain angle, the safety belt buckle 25 will slide out from the gap between the block 19 and the safety guide rail 18, and the block 19 will be quickly reset under the action of the spring 23, so that the safety belt buckle 25 can rise as the person climbs. When installing the equipment, the tools can be placed in the tool box 1 to prevent the people below from being hit.

[0028] If a person falls from a height, the block 19 cannot rotate downward because the protruding block 13 and the safety limit block 20 block its downward rotation trajectory, and the protruding block 13 between the ladder bracket 9 and the safety guide rail 18 blocks the gap between the block 19 and the safety guide rail 18, so the safety belt buckle can only slide upward, so that the safety belt buckle 25 can only be above the block 19 to ensure the safety of the climbers.

[0029] 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.
