Description

Technical Field

[0001] The utility model relates to the technical field of anti-falling safety of a construction climbing frame, in particular to an anti-falling device for a construction climbing frame. Background Art

[0002] As an innovative type of climbing frame, construction climbing scaffolding plays a vital role in high-rise building construction. It can be raised and lowered as the building progresses. This design eliminates the need for repeated disassembly and assembly like traditional scaffolding. Instead, it can be assembled once and used until construction is complete. This feature not only significantly reduces labor costs, reducing the physical effort and time expended by construction workers during disassembly and assembly, but also saves a significant amount of material. It avoids the loss and waste of materials caused by repeated disassembly and assembly, effectively improving material utilization.

[0003] Furthermore, from a safety perspective, construction climbing frames represent a significant improvement over traditional scaffolding. However, the guide rails connecting existing construction climbing frames to the fall arrester are monorail. During actual construction, if the climbing frame suddenly falls, the fall arrester will instantly experience a tremendous impact force due to the fall-stopping crossbar. This impact force far exceeds the normal capacity of the fall arrester, posing a risk of the fall arrester loosening. If the fall arrester loosens, the consequences of the climbing frame falling would be disastrous, posing a serious threat to the lives of construction workers and causing significant losses and negative impacts to the entire construction project.

[0032] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0033] The following combination Figures 1 to 6 , describing the embodiments of the present utility model.

[0034] According to an embodiment of the present utility model, a construction climbing frame anti-falling device is provided, comprising:

[0035] Mounting block 1, which is fixedly mounted on the outer surface of the building;

[0036] At least two guide rails 2 are arranged parallel to each other, and the guide rails 2 are slidably mounted on the mounting block 1 along their length directions, and a plurality of locking rods 3 are arranged at intervals along the length directions of the guide rails 2;

[0037] At least two sets of locking assemblies, one end of the locking assembly is rotatably mounted on the mounting block 1, and the other end is provided with a locking portion, the locking assembly has a first position in which the locking portion and the locking rod 3 are engaged with each other when the guide rail 2 falls, a second position in which the locking portion is located between two adjacent locking rods 3 during normal construction, and a third position in which the locking portion is located on one side of the guide rail 2 when the guide rail 2 is raised or lowered.

[0038] As will be readily understood, mounting block 1 is fixed to the exterior surface of a building and can be secured by bolting, welding, or pre-embedded connections. The specific securing method for mounting block 1 is not limited herein; it is sufficient to ensure safety and stability. To ensure connection strength, mounting block 1 may be constructed using triangular steel members. Of course, other shapes or materials may also be used depending on actual needs, and no specific limitations are imposed herein.

[0039] It should be noted that the guide rail 2 is fixedly mounted on the scaffold of the construction climbing frame anti-fall device, and the scaffold can be constructed and adjusted according to the height of the building.

[0040] Specifically, in this embodiment, the number of guide rails 2 is set to two. These two guide rails 2 share the weight of the climbing frame, construction personnel, and equipment, resulting in more even weight distribution and reducing the concentration of force on a single guide rail 2, thereby improving overall stability. In other embodiments, an appropriate number of guide rails, such as three, four, or more, may be selected based on actual installation conditions.

[0041] As will be readily understood, the locking rods 3 are spaced apart along the length of the guide rail 2. This ensures that they can engage with the locking portion of the locking assembly at various locations, effectively locking the guide rail 2. The locking rods 3 are typically made of high-strength metal, capable of withstanding significant impact and tensile forces. In the event of an emergency, such as a fall of the climbing frame, the locking rods 3 must securely engage the locking portion, preventing the guide rail 2 from further movement.

[0042] It is easy to understand that the number of the locking rods 3 on the guide rail 2 needs to be determined according to factors such as the height of the climbing frame, the load-bearing capacity and safety requirements. There is no restriction on the specific number here.

[0043] It is easy to understand that the connection method between the retaining rod 3 and the guide rail 2 is usually welding connection, bolt connection or integrated casting. The welding connection and integrated casting methods are firm and reliable, and not easy to loosen or fall off. However, after installation, it is difficult to disassemble and adjust. If the retaining rod 3 or the guide rail 2 needs to be repaired or replaced, it may be necessary to use cutting and other methods, which is more complicated to operate. Bolt connection has the advantage of high installation flexibility, and the position and spacing of the retaining rod 3 can be adjusted according to actual conditions. When repairing and replacing, you only need to remove the bolts, and the operation is relatively simple. Here, the connection method between the retaining rod 3 and the guide rail 2 is not limited, and it is determined according to the actual requirements of production and construction.

[0044] It should be noted that in the first and second positions of the locking assembly, the locking assembly itself does not move. During normal construction, the locking assembly is in the second position. At this time, the locking portion is located between two adjacent locking rods 3. When the guide rail 2 falls, the locking portion of the locking assembly and the locking rod 3 are engaged with each other, and the locking assembly switches to the first position. Through the tight engagement between the locking portion and the locking rod 3, emergency safety protection is provided for the construction workers, preventing the occurrence of falling accidents and ensuring life safety. When the guide rail 2 is raised or lowered, the locking assembly rotates to the third position under the action of external force, and is on the side of the guide rail 2. Avoiding interference with the guide rail 2 and the locking rod 3 will not hinder the rising or falling movement of the guide rail 2, ensuring that the climbing frame can be smoothly raised and lowered as the building construction progresses.

[0045] The anti-fall device for the construction climbing frame provided in this embodiment increases the overall stability of the climbing frame by providing at least two parallel guide rails 2. In the event of a fall, the locking assemblies on multiple guide rails 2 can function simultaneously, thereby improving the reliability of safety protection. When the guide rail 2 falls, the locking portion of the locking assembly can quickly engage with the locking rod 3, effectively preventing the falling trend, providing strong safety protection for construction personnel, and greatly reducing the probability of falling accidents. In addition, the locking assembly can be flexibly switched between different positions. When the guide rail 2 is raised or lowered, it is in the third position, which does not affect the normal lifting and lowering operation of the climbing frame, making the construction process smoother and more efficient.

[0046] Furthermore, the locking assembly includes:

[0047] A locking member 41 is provided with a locking portion;

[0048] The rotating member 42 is rotatably mounted on the mounting block 1;

[0049] One end of the connecting rod 43 is fixedly connected to the rotating member 42 , and the other end is fixedly connected to the locking member 41 . The locking member 41 can be switched among the first position, the second position and the third position under the drive of the rotating member 42 .

[0050] In detail, the locking portion is a structural member with an opening, with the opening facing the locking rod 3. The locking member 41, the rotating member 42 and the connecting rod 43 can be processed and formed as a whole, or they can be assembled and fixed after being processed separately. The setting of the rotating member 42 allows the locking member 41 to be quickly switched between different positions. When safety protection is required, the rotating member 42 can quickly drive the locking member 41 to the first position, engage with the locking rod 3, and prevent the guide rail 2 from falling. During normal construction and the lifting and lowering of the guide rail 2, the rotating member 42 can accurately switch the locking member 41 to the second position or the third position without affecting the construction operation and the movement of the guide rail 2, thereby improving the efficiency and flexibility of the construction.

[0051] Of course, a hydraulic cylinder can also be used to replace the combination of the rotating member 42 and the connecting rod 43. The locking member 41 is connected to the mounting block 1 via the hydraulic cylinder. The telescopic rod of the hydraulic cylinder is connected to the locking member 41, and the cylinder body is fixed to the mounting block 1. This can then be integrated with the control system to achieve automated operation, reduce manual intervention, and improve construction efficiency and safety. In some optional embodiments, an electric push rod can also be used to drive the rotating member 42 and the connecting rod 43 to achieve automation. The setting method of its control system is not limited here, and it is sufficient to ensure the stable rotation of the locking member 41.

[0052] Furthermore, it also includes:

[0053] The rotating shaft 5 is fixedly mounted on the mounting block 1 , and the axial direction of the rotating shaft 5 is parallel to the length direction of the locking rod 3 . At least two rotating members 42 are sequentially arranged on the rotating shaft 5 .

[0054] It should be noted that the additional rotating shaft 5 provides stable support for the rotating member 42. Compared with the independent installation of a single rotating member 42, multiple rotating members 42 are arranged in sequence on the same rotating shaft 5, making the structure of the entire locking assembly more compact and stable.

[0055] In other embodiments, a gear transmission system may be selected, where a plurality of gears are mounted on the mounting block 1 , and the gears are meshed with each other to replace the rotating shaft 5 .

[0056] Furthermore, it also includes an elastic locking member, one end of the elastic locking member is connected to the mounting block 1, and the other end is connected to the rotating shaft 5, and the elastic locking member is arranged in contact with the rotating member 42. The elastic locking member has a first state in which the locking member 41 is in the second position when it is not in elastic deformation, and a second state in which the locking member 41 is in the third position when elastic deformation occurs.

[0057] It is easy to understand that the elastic force can ensure that the locking member 41 is in the second position, reducing the problem of non-reset due to mechanical failure or human operational error, and improving the reliability of the entire climbing system.

[0058] Furthermore, the elastic locking member is a torsion spring 6 .

[0059] Furthermore, the length of one connecting rod 43 in at least two locking assemblies is greater than the length of the other connecting rod 43 , and the corresponding locking rods 3 in at least two guide rails 2 are staggered and arranged at intervals along the length direction of the guide rail 2 .

[0060] As will be readily understood, the staggered arrangement of the locking rods 3 adapts to the varying motion paths and stresses of the guide rail 2, ensuring effective locking in all operating conditions. When the guide rail 2 falls, due to the varying lengths of the multiple connecting rods 43, even if one locking member 41 fails to fully engage with the locking rod 3, at least one of the remaining locking members 41 is guaranteed to engage with the locking rod 3. This ensures that the locking rod 3 is promptly engaged by the locking assembly regardless of its position, enhancing safety and reliability.

[0061] Furthermore, there are two guide rails 2, and the two guide rails 2 are arranged to form a whole, and the working surfaces of the guide rails 2 are on the same plane. The two guide rails 2 are provided with slide rails 7 on both sides along their length directions, and the mounting block 1 is correspondingly provided with two sliders 8, and the two sliders 8 are correspondingly slidably arranged in the slide rails 7.

[0062] As will be readily understood, the two guide rails 2 are fitted together to form a single unit, increasing their overall strength and rigidity. Compared to a single guide rail 2, the overall structure is more stable, better able to withstand the weight of the climbing frame, construction personnel, and equipment, and reducing the risk of deformation or bending of the guide rails 2 during use. Of course, in other embodiments, the two guide rails 2 may be positioned separately or oppositely, and the specific arrangement and installation method of the guide rails 2 are not limited herein.

[0063] Optionally, the locking member 41 is provided with two locking portions, which are sequentially arranged along a length direction perpendicular to the guide rail 2 and are at different levels.

[0064] It is easy to understand that providing two locking portions increases the probability of locking with the locking rod 3. When the guide rail 2 falls, even if one locking portion fails to lock with the locking rod 3 in a timely and accurate manner, the other locking portion may still work, thereby improving the reliability of the locking assembly and reducing the risk of the guide rail 2 continuing to fall.

[0065] In some optional embodiments, only one stop portion or more stop portions of design quantity and form may be provided. Here, no restriction is placed on the specific arrangement form.

[0066] Furthermore, the locking rod 3 is a round rod, and the locking portion is provided with a groove that conforms to the outer circumference of the round rod.

[0067] As is easy to understand, the round rod-shaped locking rod 3 and the locking portion provided with the conformable groove can achieve a tight fit. When the locking portion is engaged with the locking rod 3, the groove and the outer circumference of the round rod are perfectly matched, making the locking more secure and stable, and reducing the possibility of loosening or displacement after locking.

[0068] In some optional embodiments, the locking rod 3 can also be configured as a square rod, and the locking portion can be configured as a square groove. The square locking rod 3 and groove can be processed using relatively simple processes such as milling, which is relatively low in cost. In some cases, the square rod may be easier to connect and fix with other components, increasing the stability of the overall structure, but it is relatively difficult to detach from the locking portion. Here, the specific shapes of the locking rod 3 and the locking portion are not restricted, as long as they ensure stable clamping.

[0069] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
