[0039] The following is a description of a preferred embodiment of this invention in conjunction with the accompanying drawings.

[0040] refer to Figure 1-12 As shown, this utility model embodiment provides an adjustable angle steel staircase protection device, including: a base 10 and an adjusting end 20;

[0041] The base 10 includes: a fixing part for fixed connection with one side of the staircase; the base 10 includes a first direction and a second direction, the first direction and the second direction are perpendicular; when the base 10 is fixed to one side of the staircase, the base 10 can be parallel to the plane where the stair steps are located, or it can be at a first angle, the first angle being greater than 0 degrees and less than 90 degrees.

[0042] The base 10 is provided with a first connecting part 101 above it. The first connecting part includes a rotating shaft 102. The axis of the rotating shaft is consistent with the second direction.

[0043] The adjusting end 20 has a second connecting part 201 at one end, and the second connecting part 201 is rotatably connected to the rotating shaft 102 of the first connecting part 101. The second end of the adjusting end is used to connect to the guardrail.

[0044] The steel staircase protection device further includes a limiting device, which is used to limit the relative movement of the adjusting end and the base.

[0045] In this embodiment, the fixing part is used to fix the base and one side of the stairs. In actual construction, the protective device is installed on both sides of the stairs. Specifically, it can be installed on the steps, on the steel structure on the side of the stairs, or on the steel plate on the side or next to the stairs to play a protective role.

[0046] Optionally, the fixing part is used for fixed connection with a steel plate on one side of the steel staircase. The steel plate on one side of the steel staircase can be aligned with the extension direction of the handrail installed on the steel staircase.

[0047] Safety devices for steel staircases generally include a guardrail and a handrail at the top. The adjustable-angle steel staircase safety device of this invention is used to fix the guardrail. The lower part of the guardrail is connected to the adjusting end 20, and the upper part is connected to the handrail. The guardrail is generally installed vertically, and the adjusting end can be adjusted to a vertical angle, facilitating the installation of the guardrail.

[0048] In this embodiment, the first direction and the second direction refer to the length or width direction of the base, not the height direction of the base.

[0049] Specifically, the first direction can be the length direction, and the second direction can be the width direction.

[0050] In another optional implementation, the first direction is the length of the inclined plane where the stairs are located during installation, and the second direction is the width of the inclined plane where the stairs are located during installation. Here, the inclined plane where the stairs are located refers to the surface of the supporting inclined plane where the stairs are at a certain angle to the ground.

[0051] Specifically, the first direction is the length direction, which is also the length direction of the slope where the stairs are located during installation. That is, during installation, the first direction of the base is consistent with the length direction of the slope where the stairs are located.

[0052] In this embodiment, when the base 10 is fixed to one side of the staircase, the base 10 can be parallel to the plane where the stair steps are located, or it can be at a first angle. In this embodiment, the base can be installed in various positions, without limiting the installation location, thus providing greater adaptability.

[0053] Optionally, when the base is fixed to one side of the staircase, it is fixed to a steel plate on one side of the staircase, and the direction of the steel plate on one side of the staircase is consistent with the direction of the inclined plane where the steel staircase is located.

[0054] In this embodiment, the limiting device is used to restrict the relative movement between the adjusting end and the base. Since the adjusting end can rotate relative to itself to adjust its angle, it is necessary to fix the position of the adjusting end after it is adjusted to the correct position. The limiting device is the mechanism used to fix the position of the adjusting end, ensuring the stability of the adjusting end structure during use.

[0055] Specifically, the limiting device can be an existing limiting structure, such as a screw structure or a rivet structure. The limiting structure can be set between the first connecting part and the second connecting part, such as using a spring pin and a slot to achieve positioning.

[0056] In one optional embodiment, the first connecting portion 101 includes two opposing ear plates 103, the two ear plates being oriented in the same direction as the first direction, and the rotating shaft 102 being disposed between the two ear plates.

[0057] The direction of the ear plate is the direction in which the ear plate surface extends.

[0058] Optionally, the two ear plates 103 are provided with through holes 104, and bolts pass through the through holes to form the rotating shaft 102. That is, the rotating shaft 102 can be a bolt.

[0059] Optionally, a nut is welded to the outside of one of the ear plate through holes, and the bolt is threadedly connected to the nut.

[0060] Optionally, the second connecting part 201 includes a connecting plate 202 with an opening, and the rotating shaft 102 is installed in the opening.

[0061] Optionally, the connecting plate is provided with clearance portions on both sides to facilitate rotation of the connecting plate. For example... Figure 4 As shown, there are clearance sections on both sides.

[0062] Optionally, in this embodiment, the limiting structure is fixed by bolts. The limiting device includes at least two fixing holes 105 and bolts, with at least two fixing holes 105 provided on one of the ear plates, and the bolts can pass through the fixing holes to fix the connecting plate.

[0063] Optionally, the fixing hole in this embodiment can be a threaded hole, and the bolt passes through the fixing hole to hold the connecting plate and play a fixing role.

[0064] In another optional implementation, the fixing hole in this embodiment can be a through hole, with a nut welded to the outside of the through hole. The bolt passes through the fixing hole and the nut to fix the connecting plate. Specifically, the bolt can abut against the connecting plate to achieve a fixing function. Alternatively, a corresponding groove can be provided on the connecting plate to accommodate the bolt and achieve a fixing function.

[0065] refer to Figure 3 As shown, in this embodiment, the base 10 includes a top plate 106 and two side plates 107. The two side plates 107 are vertically connected to the top plate 106. The two side plates are provided with mounting grooves 108 on their sides. The top plate 106 has at least two holes. During installation, the steel structure on one side of the staircase is embedded in the mounting groove 108. The base is fixed to the steel structure by inserting bolts into the holes on the top plate to hold the steel plate.

[0066] Specifically, the steel structure can be made of steel plates, specifically the steel plate on one side of the staircase, with the surface of the steel plate aligned with the slope of the staircase.

[0067] Optionally, nuts are welded to the outside of the two holes on the top plate 106, and bolts are threadedly connected to the nuts.

[0068] Optionally, the holes on the top plate are threaded holes, and the bolts are threaded into the holes.

[0069] Optionally, the adjusting end also includes a fixing tube, which is fixedly connected to the connecting plate for fixing the guardrail. The fixing tube has several holes evenly opened around its circumference, and several bolts are inserted into the holes to fix the guardrail.

[0070] Optionally, the fixed pipe 203 can have four holes on its wall, evenly arranged along the circumference of the fixed pipe. Nuts are welded to the outside of the holes, and bolts are threadedly connected to the nuts to enter and exit the holes to fix the guardrail.

[0071] Furthermore, the guardrail has corresponding openings, and bolts are inserted into the holes on the fixing pipe and then into the holes on the guardrail to fix the guardrail.

[0072] Optionally, a nut is welded to the outside of the hole in the fixed pipe wall to secure the bolt. The nut and bolt are connected by a thread.

[0073] In this embodiment, "outside the hole" refers to the outer side of the hole, and does not specifically refer to the outer wall of the pipe where the hole is located; it can be the inner wall of the guardrail.

[0074] In this embodiment, a handrail may be installed on the upper part of the guardrail.

[0075] In this embodiment, the bolts connecting the ear plate and the connecting plate can be M12 bolts, and the corresponding nuts welded to the outside of the through holes in the ear plate are M12 nuts. The fixing holes on the ear plate can be M6 holes, with M6 nuts outside the holes, and the corresponding bolts are M6 bolts.

[0076] In this embodiment, the angle adjustment is mainly achieved through the synergistic action of the M12 / M6 bolt assembly. The M12 bolt is used to connect the adjustment end and the base, providing the main connection and adjustment force. The M6 ​​bolt is used for auxiliary fixing and fine-tuning to ensure that the adjusted angle is stable and reliable.

[0077] When adjusting the angle of the device, first loosen the M6 ​​bolts to allow the adjusting end to rotate relative to the base. Rotate the adjusting end to match the actual angle of the staircase. During adjustment, the M6 ​​bolts serve as auxiliary positioning to prevent the adjusting end from shifting during the adjustment process. Once the appropriate angle is achieved, tighten the M12 bolts to secure the adjusting end to the base. At this point, further tighten the M6 ​​bolts to enhance the stability of the connection.

[0078] The adjustable end is detachably connected to the base using a combination of bolts and a locking mechanism. The bolts provide reliable connection force, ensuring the adjustable end will not loosen during use. The locking mechanism serves to position and guide the adjustable end, allowing it to be accurately mounted on the base.

[0079] Based on the analysis of the three-dimensional mechanical model, the angle adjustment mechanism in this embodiment exhibits excellent angle adaptability. By adjusting the M12 / M6 bolt assembly at different staircase angles, the protective components of the device can always remain perpendicular to the staircase, thus providing optimal protection. Furthermore, the three-dimensional mechanical model also shows that under various loads, the angle adjustment mechanism can effectively transfer the load to the staircase structure, ensuring the stability and safety of the device.

[0080] In this embodiment, the adjustable angle steel staircase protection device, although made of Q345 steel plate, adopts a modular design and standardized interface in its structure. This improves the material utilization rate and reduces the scrap rate during the production process, so that the material cost is not significantly increased compared with traditional protection devices.

[0081] In terms of construction time, adjustable protective devices significantly improve installation efficiency, reducing labor costs and construction time. For example, a medium-sized construction project using traditional protective devices would have a construction period of 10 days, while using adjustable protective devices would only require 5 days, halving the construction period. Considering both material and construction costs, the total cost of adjustable protective devices is approximately 20% lower than that of traditional protective devices.

[0082] Furthermore, standardized production plays a positive role in promoting the development of green buildings. Standardized production makes the production process of protective devices more standardized and efficient, reducing energy consumption and environmental pollution. At the same time, the high reusability of the devices aligns with the resource-saving concept of green buildings, contributing to the sustainable development of the construction industry.

[0083] This embodiment provides an adjustable-angle steel staircase safety device, including a base and an adjusting end. The base is fixed to the steel staircase, and the adjusting end is fixed to the guardrail. The angle is adjusted by adjusting the adjusting end to accommodate guardrails of different steepnesses. Furthermore, in this embodiment, the base can be secured to a steel plate via a mounting slot, and the base and steel plate are fixed with bolts. The structure is stable, installation is simple, and no welding is required. Disassembly only requires loosening the bolts. Moreover, the adjusting end can also be fixed to the guardrail with bolts and can also be removed, allowing the safety device to be reused and greatly increasing its utilization rate.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
