Description

Technical Field

[0001] This utility model relates to the field of auxiliary components for engineering ladders, specifically to a safety reinforcement support rod for a single-sided straight ladder. Background Technology

[0002] During construction, when quality inspections are required on high walls, construction ladders are often used as climbing tools. However, existing single-frame construction ladders, when used against walls, are prone to swaying and instability due to the lack of stabilizing mechanisms. This poses a significant safety hazard when used for single-sided or single-sided support. Utility Model Content

[0003] The purpose of this utility model is to provide a safety reinforcement strut for a single-sided straight ladder in order to solve the above problems, as detailed below.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This utility model provides a safety reinforcement support for a single-sided straight ladder, including a ladder connecting square tube and a wall connecting square tube. The ladder connecting square tube and the wall connecting square tube are both horizontally arranged and located at the front and rear respectively. Longitudinal telescopic support rods are assembled and installed on both sides of the ladder connecting square tube and the wall connecting square tube, and the longitudinal telescopic support rods are all arranged along the longitudinal direction.

[0006] A connecting rod is horizontally fixed between the outer peripheries of the two longitudinal telescopic support rods, and an oblique telescopic support rod is fixedly connected to the middle part of the connecting rod at an angle downwards, with the bottom end of the oblique telescopic support rod tilted forward.

[0007] The front two sides of the supporting square tube and the bottom of the inclined telescopic support rod are all equipped with ladder step buckles for locking the ladder steps by means of connectors.

[0008] The middle part of the wall-supporting connecting square tube is detachably equipped with an anti-movement support component, which is used to achieve stable anti-movement support for a single engineering ladder in both single-sided and single-sided support environments.

[0009] Preferably, both the ladder connecting square tube and the wall connecting square tube are rectangular steel pipes, and the front and rear ends of the longitudinal telescopic support rod are welded to the corresponding ladder connecting square tube and wall connecting square tube by means of welding parts.

[0010] Preferably, both the longitudinal telescopic support rod and the diagonal telescopic support rod are double-section pull-out telescopic rods with limiting locking mechanisms.

[0011] Preferably, the oblique telescopic part of the oblique telescopic support rod is located at the upper part and is welded and fixed to the connecting support rod.

[0012] Preferably, the longitudinal telescopic part of the longitudinal telescopic support rod is located at the rear and is welded and fixed to the supporting wall connecting square tube.

[0013] Preferably, the connecting rod is a multi-section rod and the sections are connected together by connecting sleeves.

[0014] Preferably, the ladder step fasteners are all U-shaped fasteners with U-shaped notches facing forward and placed horizontally, and the ladder step fasteners are all fixed to the corresponding connectors by riveting.

[0015] Preferably, the anti-motion support component includes a buffer support block and a mounting slot. The buffer support block is horizontally positioned, and the mounting slot is formed on the bottom surface of the buffer support block along the horizontal direction. The buffer support block is locked onto the outside of the wall-connecting square tube by means of vertical sliding cooperation with the wall-connecting square tube through the mounting slot. The front of the buffer support block is a flat support surface, and the back of the buffer support block is a single-sided support surface with a V-shaped surface. The single-sided support surface has a right-angle slot in the recessed position.

[0016] Preferably, the buffer support block is a plastic block or a rubber block, and multiple anti-movement protrusions are integrally fixedly provided on the surfaces of the planar support surface and the single-sided support surface, and the anti-movement protrusions are evenly distributed side by side.

[0017] Preferably, the front sides of the wall-supporting connecting square tube are provided with mounting holes along the longitudinal direction, and the front sides of the buffer support block are provided with mating holes along the longitudinal direction. Both the mounting holes and the mating holes are through threaded holes, which are used to fix the buffer support block to the outside of the wall-supporting connecting square tube by adding screws through each set of corresponding mounting holes and mating holes.

[0018] The aforementioned safety reinforcement strut for a single-sided straight ladder, in practical use, utilizes the ladder step fasteners at the front of the ladder connecting square tube and the front of the longitudinal telescopic support rod to respectively secure the upper and lower ladder steps of the single-frame engineering ladder. Then, by using the wall-supporting connecting square tube to abut against the wall, effective and stable support can be achieved when the single-frame engineering ladder is used for single-sided or single-sided support, preventing swaying during single-sided or single-sided support use, thus promoting safe use. Furthermore, because the wall-supporting connecting square tube is externally equipped with an anti-movement support component, the front and rear ends of the buffer support block of the anti-movement support component are respectively the planar support surface and the single-sided support surface. Simultaneously, the single-sided support surface is V-shaped and has a right-angle slot in the recessed position. Therefore, when the single-frame engineering ladder is used for single-sided support, the right-angle slot secures it to the single-sided stress position, achieving stable anti-movement support for the single-frame engineering ladder. When used for single-sided support of a single engineering ladder, the planar support surface, when attached to the single-sided stress position, provides stable anti-movement support for the ladder, enriching the application environment of the anti-movement support component. The buffer support block can be quickly assembled onto the outside of the support wall connecting square tube by using the mounting slot and screws through the mounting holes and mating holes. Simply removing the screws allows the mounting slot to be vertically removed from the outside of the support wall connecting square tube, enabling the buffer support block to be detached. The assembly and disassembly of the buffer support block on the outside of the support wall connecting square tube is simple and easy to implement. This facilitates adjusting the buffer support block so that the planar support surface and the single-sided support surface face backward, allowing for flexible adjustment of the buffer support block's usage posture to adapt to different application environments. It also facilitates subsequent replacement and maintenance after the buffer support block is removed.

[0019] The beneficial effects are as follows: 1. This utility model uses the ladder step buckles at the front of the ladder connecting square tube and the front of the longitudinal telescopic support rod to respectively lock the upper and lower ladder plates of a single engineering ladder, and then uses the wall connecting square tube to abut against the wall. This can achieve effective and stable support for a single engineering ladder when it is used for single-sided or single-sided support, and avoid the single engineering ladder from shaking during single-sided or single-sided support, which is conducive to the safe use of the single engineering ladder.

[0020] 2. The external assembly of the wall-supporting connecting square tube is equipped with an anti-movement support component. The front and rear ends of the buffer support block of the anti-movement support component are a planar support surface and a single-sided support surface, respectively. The single-sided support surface is a V-shaped surface with a right-angle slot in the recessed position. When a single engineering ladder is used for single-sided support, the right-angle slot is used to lock and stick to the single-sided stress position to achieve stable anti-movement support for the single engineering ladder. At the same time, when a single engineering ladder is used for single-sided support, the planar support surface is used to stick to the single-sided stress position to achieve stable anti-movement support for the single engineering ladder, thus enriching the application environment of the anti-movement support component.

[0021] 3. By installing the mounting slot onto the wall-supporting connecting square tube and adding screws through the mounting holes and mating holes, the buffer support block can be quickly assembled onto the outside of the wall-supporting connecting square tube. Simply removing the screws allows the mounting slot to be vertically removed from the outside of the wall-supporting connecting square tube, thus enabling the buffer support block to be detached. The assembly and disassembly of the buffer support block on the outside of the wall-supporting connecting square tube is simple and easy to implement. This facilitates adjusting the buffer support block so that the flat support surface and the single-sided support surface face backward, allowing for flexible adjustment of the buffer support block's usage posture to adapt to different usage environments. It also facilitates subsequent replacement and maintenance after the buffer support block is removed. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] See Figures 1-2 As shown, this utility model provides a safety reinforcement support for a single-sided straight ladder, including a ladder connecting square tube 3 and a wall connecting square tube 1. Both the ladder connecting square tube 3 and the wall connecting square tube 1 are horizontally arranged and located at the front and rear respectively. Longitudinal telescopic support rods 2 are assembled and installed on both sides of the ladder connecting square tube 3 and the wall connecting square tube 1, and the longitudinal telescopic support rods 2 are all arranged longitudinally. A connecting support rod 10 is horizontally fixed between the outer peripheries of the two longitudinal telescopic support rods 2, and an inclined telescopic support rod 5 is fixedly connected to the middle of the connecting support rod 10 at a downward inclination. The bottom end of the inclined telescopic support rod 5 is inclined towards... The front sides of the ladder connecting square tube 3 and the bottom of the diagonal telescopic support rod 5 are all equipped with ladder step buckles 4 for locking the ladder steps by connecting parts 6. The purpose of this setting is to use the ladder step buckles 4 at the front of the ladder connecting square tube 3 and the front of the longitudinal telescopic support rod 2 to lock the upper and lower ladder steps of the single engineering ladder respectively. Then, by using the wall connecting square tube 1 to abut against the wall, effective and stable support can be achieved when the single engineering ladder is used for single-sided or single-sided support, so as to avoid the single engineering ladder from shaking during single-sided or single-sided support.

[0029] See Figure 1As shown, the middle part of the wall-supporting connecting square tube 1 is detachably equipped with an anti-movement support component 7, which is used to provide stable anti-movement support for a single engineering ladder under single-sided support and single-sided support conditions. Specifically, the anti-movement support component 7 includes a buffer support block 705 and a mounting slot 706. The buffer support block 705 is horizontally positioned, and the bottom surface of the buffer support block 705 has a mounting slot 706 along the horizontal direction. The buffer support block 705 is locked onto the outside of the wall-supporting connecting square tube 1 by vertical sliding cooperation with the mounting slot 706. The front of the buffer block 705 is a flat support surface 701, and the back of the buffer block 705 is a V-shaped single-sided support surface 702. The single-sided support surface 702 has a right-angle slot 704 in the recessed position. The purpose of this design is that when a single engineering ladder is used for single-sided support, the right-angle slot 704 is used to lock and stick to the single-sided stress position to achieve stable anti-movement support for the single engineering ladder. At the same time, when a single engineering ladder is used for single-sided support, the flat support surface 701 is used to stick to the single-sided stress position to achieve stable anti-movement support for the single engineering ladder.

[0030] See Figures 1-2 As shown, the following optimizations were made to this scheme. Specifically, both the ladder connecting square tube 3 and the wall connecting square tube 1 are rectangular steel pipes, and the front and rear ends of the longitudinal telescopic support rod 2 are welded and fixed to the surfaces of the corresponding ladder connecting square tube 3 and wall connecting square tube 1 via welding parts 8. This ensures that the front and rear ends of the longitudinal telescopic support rod 2 are stably fixed to the surfaces of the corresponding ladder connecting square tube 3 and wall connecting square tube 1, preventing accidental separation. Optionally, both the longitudinal telescopic support rod 2 and the diagonal telescopic support rod 5 are double-section pull-out telescopic rods with limiting locking joints 11. This allows for adaptive adjustment of the position of the ladder step buckle plate 4 using the longitudinal telescopic support rod 2 and the diagonal telescopic support rod 5, ensuring that the ladder step buckle plate 4 can be secured to the steps of the single-frame engineering ladder. Furthermore, the oblique telescopic part 501 of the oblique telescopic support rod 5 is located at the upper part and is welded and fixed to the connecting support rod 10, and the longitudinal telescopic part 201 of the longitudinal telescopic support rod 2 is located at the rear part and is welded and fixed to the wall-supporting connecting square tube 1, so that the oblique telescopic part 501 and the longitudinal telescopic part 201 can be stably fixed to the corresponding connection position by means of welding and fixing, so as to prevent accidental separation.

[0031] See Figures 1-2As shown, the connecting support rod 10 consists of multiple sections, which are connected together by connecting sleeves 9. This allows the connecting support rods 10 to be assembled together using the connecting sleeves 9, thereby enabling the combined installation of the inclined telescopic support rod 5. Optionally, the ladder step plates 4 are all U-shaped plates with U-shaped notches facing forward and placed horizontally. Furthermore, the ladder step plates 4 are all fixed to the corresponding connecting parts 6 by riveting, ensuring that the ladder step plates 4 have a design shape that meets the usage requirements and can stably hold the steps of a single engineering ladder. Optionally, the buffer support block 705 is a plastic or rubber block, and multiple anti-movement protrusions 703 are integrally fixedly provided on the surfaces of the planar support surface 701 and the single-sided support surface 702. These anti-movement protrusions 703 are evenly distributed side-by-side to enhance the frictional anti-movement stability of the buffer support block 705 through the compression deformation of the anti-movement protrusions 703. Furthermore, mounting holes 708 are longitudinally provided on both sides of the front of the support wall connecting square tube 1, and mating holes 707 are longitudinally provided on both sides of the front of the buffer support block 705. Both the mounting holes 708 and the mating holes 707 are through-threaded holes, used to allow the passage of each set of corresponding... The buffer support block 705 is fixedly installed on the outside of the wall-supporting connecting square tube 1 by adding screws through the mounting hole 708 and mating hole 707. With this configuration, the buffer support block 705 can be quickly assembled on the outside of the wall-supporting connecting square tube 1 by using the mounting slot 706 to lock onto the wall-supporting connecting square tube 1 and by adding screws through the mounting hole 708 and mating hole 707. At the same time, the mounting slot 706 can be vertically removed from the outside of the wall-supporting connecting square tube 1 by simply removing the screws, thereby removing the buffer support block 705 from the outside of the wall-supporting connecting square tube 1. The assembly and disassembly of the buffer support block 705 on the outside of the wall-supporting connecting square tube 1 is simple and easy to implement.

[0032] Using the above structure, in practical use, the ladder step fasteners 4 at the front of the ladder connecting square tube 3 and the front of the longitudinal telescopic support rod 2 respectively lock the upper and lower ladder steps of the single engineering ladder. Then, by using the wall-supporting connecting square tube 1 to abut against the wall, effective and stable support can be achieved when the single engineering ladder is used for single-sided or single-sided support, preventing swaying during single-sided or single-sided support, thus promoting safe use. Furthermore, because the wall-supporting connecting square tube 1 is externally equipped with an anti-movement support component 7, the front and rear ends of the buffer support block 705 of the anti-movement support component 7 are respectively a planar support surface 701 and a single-sided support surface 702. The single-sided support surface 702 is a V-shaped surface with a right-angle slot 704 in the recessed position. Therefore, when the single engineering ladder is used for single-sided support, the right-angle slot 704 locks against the single-sided force-bearing position, achieving stable anti-movement support for the single engineering ladder. When the surface support is in use, by attaching the flat support surface 701 to the single-sided stress position, stable anti-movement support can be achieved for a single engineering ladder, enriching the usage environment of the anti-movement support component 7. Since the buffer support block 705 can be quickly assembled on the outside of the support wall connecting square tube 1 by attaching the mounting slot 706 and adding screws through the mounting hole 708 and mating hole 707, the mounting slot 706 can be vertically removed from the outside of the support wall connecting square tube 1 by simply removing the screws. This allows the buffer support block 705 to be removed from the outside of the support wall connecting square tube 1. The assembly and disassembly of the buffer support block 705 on the outside of the support wall connecting square tube 1 is simple and easy to achieve. This makes it easy to adjust the buffer support block 705 so that the flat support surface 701 and the single-sided support surface 702 face backward, which facilitates flexible adjustment of the usage posture of the buffer support block 705 to adapt to different usage environments. At the same time, it is easy to replace and maintain the buffer support block 705 after it is removed.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
