Description

Technical Field

[0001] The utility model belongs to the field of climbing ladders, and in particular relates to a falling-proof climbing ladder for construction engineering. Background Art

[0002] During the construction of buildings, climbing ladders are often used for high-altitude operations. However, the existing climbing ladders do not have any protective measures for users when using them. If the user accidentally slips during the climbing process, he or she will fall directly from the climbing ladder, which is very dangerous. In order to ensure the safe and reliable construction, climbing ladders have gradually begun to be installed with protective cages, which can assist the climbing of high-altitude workers to a certain extent and prevent the workers from falling. For example, Chinese patent CN 220036560 U discloses a suspended cage ladder, which prevents workers from falling backwards by installing a protective cage. However, in the actual high-altitude operation process, workers still fall due to stepping on air, and the cage ladder cannot fully guarantee the personal safety of climbers.

[0003] Therefore, how to provide a fall-proof climbing ladder for construction engineering has become a problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the utility model provides a fall-proof climbing ladder for construction engineering. The utility model can connect the fall arrester to the human body through a safety rope through the arrangement of T-shaped channel steel and the fall arrester. When a person falls due to stepping on empty space, the fall can be stopped in time to ensure the safety of the climber.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a fall-proof climbing ladder for construction engineering, comprising a ladder, an anti-fall frame and an anti-fall device, the anti-fall frame is arranged around the side of the ladder for climbing, the anti-fall frame is Ω-shaped, the inner wall of the anti-fall frame is provided with a T-shaped channel steel along the direction of the anti-fall frame, the anti-fall device is slidably arranged in the T-shaped channel steel, the fall-proof device comprises a limit slider, a first spring and a locking tongue, the interior of the limit slider is provided with a locking groove, the first spring and the locking tongue are both arranged in the locking groove, the locking tongue is rotatably connected to the locking groove by a pin shaft, the locking tongue is L-shaped, and is divided into a pulling part and a resting part, a stopper is provided on the side of the pulling part away from the resting part, one end of the first spring is fixedly connected to the locking groove, and the other end of the first spring is fixedly connected to the stopper.

[0006] Furthermore, the limiting slider is provided with a concave roller corresponding to the wing plate of the T-shaped channel steel, and the limiting slider is slidably connected to the T-shaped channel steel via the concave roller.

[0007] Furthermore, a cylindrical groove is provided at the top end of the abutting portion, and a ball and a second spring are movable in the cylindrical groove, and the second spring is arranged between the ball and the cylindrical groove, one end of the second spring is in conflict with the ball, and the other end of the second spring is in conflict with the cylindrical groove.

[0008] Furthermore, a ring hook is provided at the top end of the pulling part, and the ring hook is rotatably connected to the pulling part.

[0009] Furthermore, a fixed leg is provided on a side of the ladder close to the wall.

[0010] Furthermore, the anti-fall frame includes a keel frame and an arc-shaped baffle plate, the keel frame is arranged on the ladder, and the arc-shaped baffle plate is arranged on the surface of the keel frame.

[0011] The beneficial effects of the utility model are as follows: the utility model can connect the human body through the safety rope through the arrangement of the anti-fall frame and the anti-fall device, so that the anti-fall device changes position with the climbing of the person, and will not hinder the climbing action of the climber; when the climber loses his footing and steps on empty air, the pulling force of falling will pull the locking tongue to fix the anti-fall device on the T-shaped channel steel, thereby stopping the person from falling; the arrangement of the ball and the second spring can temporarily lock the anti-fall device on the T-shaped channel steel when the person stops climbing, and can also slide along the T-shaped channel steel as the person climbs, without the need for the person to pull the anti-fall device, which is convenient for the climber to use.

[0018] Example 1

[0019] like Figure 1-3 As shown, this embodiment discloses a fall-proof climbing ladder for construction engineering, including a ladder 1, an anti-fall frame and a fall arrester. A fixed leg 4 is arranged on the side of the ladder 1 close to the wall, which is used to fix the ladder 1 on the wall. The anti-fall frame is arranged around the side of the ladder 1 for climbing. The anti-fall frame is Ω-shaped, including a keel frame 2 and an arc-shaped baffle 3. The keel frame 2 is arranged on the ladder 1 to support and fix. The arc-shaped baffle 3 is arranged on the surface of the keel frame 2 to prevent people from falling when leaning back. The inner wall of the keel frame 2 is welded with a T-shaped channel steel 5 along the direction of the keel frame 2, and the fall arrester is slidably arranged in the T-shaped channel steel 5.

[0020] Specifically, the fall arrester includes a limit slider 6, a first spring 7 and a lock tongue. A locking groove is provided inside the limit slider 6. The first spring 7 and the lock tongue are both arranged in the locking groove. The lock tongue is rotatably connected to the locking groove through a pin shaft 8. The lock tongue is L-shaped and is divided into a pulling part 9 and a supporting part 10. An annular hook 15 is provided at the top of the pulling part 9. The annular hook 15 is rotatably connected to the pulling part 9. A stopper 11 is provided on the side of the pulling part 9 away from the supporting part 10. One end of the first spring 7 is fixedly connected to the locking groove, and the other end of the first spring 7 is fixedly connected to the stopper 11. The setting of the first spring 7 can make the supporting part 10 of the lock tongue rest on the T-shaped channel steel 5 in a natural state, thereby realizing the stopping of the fall arrester at any time and preventing the fall arrester from slipping.

[0021] As a preferred embodiment of the present utility model, the limiting slider 6 is provided with a concave roller 12 corresponding to the wing plate of the T-shaped channel steel, and the limiting slider 6 is slidably connected to the T-shaped channel steel 5 through the concave roller 12 .

[0022] In order to facilitate the sliding of the fall arrester, a cylindrical groove is provided at the top of the abutment part 10, and a ball 13 and a second spring 14 are restricted in the cylindrical groove. The elastic damping of the second spring 14 is greater than the elastic damping of the first spring 7. The second spring 14 is arranged between the ball 13 and the cylindrical groove, and one end of the second spring 14 is in conflict with the ball 13, and the other end of the second spring 14 is in conflict with the cylindrical groove. The ball 13 is pushed by the second spring 14 to abut against the wing plate of the T-shaped channel steel 5, which can convert the sliding friction between the abutment part 10 and the wing plate into rolling friction without affecting the stopping of the abutment part 10, and when falling occurs, by tightening the pulling part 9, the abutment part 10 can rotate and squeeze the ball 13, and squeeze the ball 13 into the cylindrical groove, and the abutment part 10 is then locked with the wing plate, so that the sliding of the fall arrester is stopped and people are prevented from falling.

[0023] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
