[0002] Water conservancy and hydropower engineering focuses on using water resources to generate electricity, manage water resources and address engineering challenges related to water resources. Such engineering projects can cover a wide range from small-scale hydropower projects to large-scale dams and irrigation systems. The current construction site ground is generally uneven land. Construction workers will use a construction frame to assist in the work, and will set up guardrails around the construction frame to protect the safety of the workers.

[0003] The existing construction frame is usually composed of pillars, beams, connectors and scaffolding boards, etc. The height is fixed and cannot be adjusted according to the scene during construction. It is not convenient to use. In addition, the guardrail is a simple circle type (the guardrail is surrounded by a circle) or a door type frame (the door structure is more complicated). Both make it troublesome for workers to climb to the top of the construction frame. Therefore, the technical field proposes an anti-fall construction frame for construction to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-3 The utility model provides an embodiment of an anti-fall construction frame for building construction, comprising a base plate 1, a motor 2 is fixedly connected to the top of the base plate 1, a mounting frame 3 is fixedly connected to the top of the base plate 1, a threaded rod 4 is rotatably connected inside the mounting frame 3, a threaded sleeve 5 is threadedly connected to the outer side of the threaded rod 4, a connecting rod 6 is rotatably connected to the top of the threaded sleeve 5, a supporting tube 7 is fixedly connected to the four corners of the top of the base plate 1, a sliding column 8 is slidably connected to the inside of the supporting tube 7, a top plate 10 is fixedly connected to the top of the four sliding columns 8, and a connecting seat 11 is fixedly connected to the bottom of the top plate 10. When the height of the construction frame needs to be adjusted, the user can start the motor 2. Driven by the motor 2, the threaded rod 4 starts to rotate, thereby causing the threaded sleeve 5 to start moving, and then causing the connecting rod 6 to rotate, thereby achieving the raising or lowering of the top plate 10, making the work of the construction personnel more convenient.

[0028] A guardrail 12 is fixedly connected to the top of the top plate 10, and a guard door 13 is rotatably connected to the outer side of the guardrail 12. The guardrail 12 and the guard door 13 cooperate to effectively prevent construction workers from falling from the construction frame. A card slot 14 is opened inside the guard door 13, and a push rod 15 is slidably connected to the front through hole of the guardrail 12. A sliding plate 16 is slidably connected to the inside of the guardrail 12, and a rotating rod 17 is rotatably connected to the outside of the sliding plate 16. A locking rod 18 is slidably connected to the through hole of the side wall of the guardrail 12, and a spring 19 is fixedly connected to the inner wall of the guardrail 12. The user can approach the top plate 10 by climbing the telescopic ladder 21, and then press the push rod 15, so that the sliding plate 16 pushes the rotating rod 17 to rotate. Under the traction force of the rotating rod 17, the locking rod 18 begins to shrink toward the inside of the guardrail 12. At this time, the spring 19 is compressed. When the locking rod 18 completely enters the inside of the guardrail 12, the user can easily push open the protective door 13, so that the top of the top plate 10 can be climbed.

[0029] Two limit plates 20 are fixedly connected to the front side of the guardrail 12, which can prevent the guard door 13 from being accidentally pushed open from the inside by the staff. One end of the push rod 15 is fixedly connected to the outside of the sliding plate 16, and pressing the push rod 15 can drive the sliding plate 16 to move.

[0030] The other end of the rotating rod 17 is rotatably connected to the outside of the locking rod 18, and the other end of the spring 19 is fixedly connected to one end of the locking rod 18. The elastic force of the spring 19 can quickly reset the locking rod 18.

[0031] The output end of the motor 2 is fixedly connected to one end of the threaded rod 4. Driven by the motor 2, the threaded rod 4 starts to rotate, and the other end of the connecting rod 6 is rotationally connected to the inside of the connecting seat 11. The traction force of the connecting rod 6 can drive the connecting seat 11 to move.

[0032] The outside of the sliding column 8 is fixedly connected with two limit blocks 9 to prevent the sliding column 8 from falling off from the inside of the supporting tube 7. Two telescopic ladders 21 are fixedly connected to the adjacent sides of the bottom plate 1 and the top plate 10 to facilitate users to climb.

[0033] Universal wheels 22 are fixedly connected to the four corners of the bottom of the base plate 1 to facilitate the movement of the construction frame. Four ground nails 23 are installed on the outer side of the base plate 1 to fix the construction frame.

[0034] Working principle: During specific use, the user can approach the top plate 10 by climbing the telescopic ladder 21, and then press the push rod 15, so that the sliding plate 16 pushes the rotating rod 17 to rotate. Under the traction force of the rotating rod 17, the locking rod 18 begins to shrink toward the inside of the guardrail 12. At this time, the spring 19 is compressed. When the locking rod 18 completely enters the inside of the guardrail 12, the user can easily push open the protective door 13, so that the user can climb to the top of the top plate 10. When the height of the construction frame needs to be adjusted, the user can start the motor 2. Driven by the motor 2, the threaded rod 4 begins to rotate, so that the threaded sleeve 5 begins to move, and then the connecting rod 6 rotates, thereby achieving the raising or lowering of the top plate 10, making the work of the construction personnel more convenient.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
