Description

Technical Field

[0001] This utility model relates to the field of engineering safety management technology, and in particular to a safety guardrail. Background Technology

[0002] Project management is a comprehensive management process involving multiple fields. It encompasses various aspects of project management, including planning, design, construction, quality control, cost budgeting, schedule control, risk management, and final acceptance. Safety management is a crucial aspect of project management, and safety barriers, as essential facilities for ensuring the safety of personnel and equipment, play a vital role in safety management.

[0003] Currently, traditional safety guardrails widely used in the field of engineering management can play a basic protective role in daily use scenarios, but they have some shortcomings in actual use: existing guardrails generally achieve the purpose of preventing climbing by increasing the vertical height. However, this design approach has great limitations. It is not only limited by construction specifications, cost control and site adaptability, which makes it impossible to increase the height "indefinitely", but also leads to an increase in the overall size of the guardrail. This affects both aesthetics and practicality, and may also increase the difficulty of installation and maintenance due to its large size. Therefore, a new type of safety guardrail is proposed. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the problems of the aforementioned safety guardrail, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a safety guardrail that solves the problem that existing guardrails generally achieve the purpose of preventing climbing by increasing the vertical height, but the height cannot be increased indefinitely, and it also leads to an increase in the overall size of the guardrail.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a safety guardrail, comprising:

[0008] The main body includes three sets of support members and two sets of protective frames, wherein the support members are used to install the protective frames;

[0009] An anti-climbing mechanism is provided, comprising two sets of anti-climbing mechanisms, which are respectively fixedly connected to the top of two sets of protective frames. The anti-climbing mechanism is used to prevent climbers from climbing over the protective railing.

[0010] In a preferred embodiment of the safety guardrail described in this utility model, the supporting member includes a post, a rotating sleeve, and ear plates. Four sets of rotating sleeves and ear plates are provided. Each of the four sets of rotating sleeves is rotatably fitted onto the outside of the post. Each of the four sets of ear plates is fixedly connected to the side walls of the four sets of rotating sleeves. Two sets of protective frames are alternately arranged between the three supporting members. Four sets of through holes are provided on both sides of the frame of each of the two sets of protective frames. These four sets of through holes are located on the same horizontal line as the four sets of ear plates of the supporting member. Each of the two sets of protective frames is detachably connected to two sets of ear plates of an adjacent supporting member.

[0011] In a preferred embodiment of the safety guardrail described in this utility model, the ear plate is fitted with a locking nut and a connecting bolt. The locking nut passes through the ear plate and the corresponding through hole and is threadedly connected to the connecting bolt. The protective frame is detachably connected to the ear plate through the locking nut and the connecting bolt.

[0012] In a preferred embodiment of the safety guardrail described in this utility model, the anti-climbing mechanism includes a fixed plate, a mounting rod, and a rotating cylinder. Multiple sets of fixed plates and rotating cylinders are alternately arranged. The multiple sets of fixed plates are all fixedly connected to the top of the protective frame and are equidistantly arranged along the length of the protective frame. The mounting rod passes through the multiple sets of fixed plates and is fixedly connected to the multiple sets of fixed plates. The multiple sets of rotating cylinders are rotatably connected to the mounting rod through built-in bearings. The outer ring of the bearing is fixedly connected to the inner wall of the rotating cylinder, and the inner ring is interference-fitted with the mounting rod.

[0013] As a preferred embodiment of the safety guardrail described in this utility model, the rotating drum surface is provided with multiple sets of annular reinforcing ribs at equal intervals.

[0014] In a preferred embodiment of the safety guardrail described in this utility model, the surfaces of the posts, rotating sleeves, ear plates, and protective frames are all coated with anti-corrosion paint.

[0015] As a preferred embodiment of the safety guardrail described in this utility model, the bottom of the post is fixed with an installation plate, and the surface of the installation plate is provided with three sets of installation holes at equal intervals around the post.

[0016] As a preferred embodiment of the safety guardrail described in this utility model, the bottom of the post is fixed with an installation plate, and the surface of the installation plate is provided with three sets of installation holes at equal intervals around the post.

[0017] The beneficial effects of this utility model are:

[0018] 1. By setting up an anti-climbing mechanism using multiple sets of rotating cylinders, it is difficult for people to obtain a stable point of force when climbing over. While maintaining a reasonable height, the rotation of the rotating cylinders can significantly increase the difficulty of climbing and prevent climbers from climbing over the guardrail. In addition, the device is modular and can be assembled into guardrails of appropriate length according to actual needs, making it flexible in use.

[0019] 2. This application uses a rotating cylinder to prevent climbers from scaling the guardrail, thus solving the problem that increasing the guardrail height "infinitely" leads to an increase in the overall size of the guardrail, which affects both aesthetics and practicality, and also increases the difficulty of installation and maintenance due to its large size.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale.

[0029] Example 1

[0030] Reference Figure 1 - Figure 2 This is an embodiment of the present utility model, which provides a safety guardrail that can achieve safety protection and prevent climbers from climbing over the guardrail. It includes: a main body 100, which includes three sets of support members and two sets of protective frames 104. The support members are used to install the protective frames 104.

[0031] The anti-climbing mechanism 200 is provided in two sets. The two sets of anti-climbing mechanisms 200 are fixedly connected to the top of the two sets of protective frames 104 respectively. The anti-climbing mechanism 200 is used to prevent climbers from climbing over the guardrail.

[0032] When in use, the protective frame 104 is fixedly installed with the support components to form a guardrail, which serves as a safety protection; then, the anti-climbing mechanism 200 is set up to prevent climbers from climbing over the guardrail.

[0033] Example 2

[0034] Reference Figure 2 and Figure 3 This is the second embodiment of the present invention. Unlike the previous embodiment, the anti-rollover mechanism 200 includes a fixed plate 201, a mounting rod 202, and a rotating cylinder 203. Multiple sets of fixed plates 201 and rotating cylinders 203 are alternately arranged. Multiple sets of fixed plates 201 are fixedly connected to the top of the protective frame 104 and are equidistantly arranged along the length of the protective frame 104. The mounting rod 202 passes through multiple sets of fixed plates 201 and is fixedly connected to multiple sets of fixed plates 201. Multiple sets of rotating cylinders 203 are rotatably connected to the mounting rod 202 through built-in bearings. The outer ring of the bearing is fixedly connected to the inner wall of the rotating cylinder 203, and the inner ring is interference-fitted with the mounting rod 202.

[0035] Furthermore, the rotating drum 203 is made of plastic material and is hollow inside.

[0036] Furthermore, the surface of the rotating drum 203 is smooth and has multiple sets of annular reinforcing ribs arranged at equal intervals;

[0037] It should be noted that the rotating drum 203 is made of plastic material, which is easy to process. The interior of the rotating drum 203 is hollow, which helps to reduce the overall weight of the device. Furthermore, its inner wall is fixed with bearings through injection molding, and the mounting rod 202 passes through the inner ring of the bearing and is interference-fitted with it, ensuring that the rotating drum 203 can rotate freely around the mounting rod 202. In addition, multiple sets of annular reinforcing ribs are equidistantly arranged on the surface of the rotating drum 203, which are used to improve the structural strength of the rotating drum 203. Therefore, the plastic rotating drum 203 achieves rotational connection through built-in bearings, which reduces weight and ensures structural strength. Moreover, this design conforms to conventional mechanical engineering methods.

[0038] When in use, applying force to the rotating cylinder 203 will cause the rotating cylinder 203 to rotate. When a climber attempts to climb over, the presence of the rotating cylinder 203 makes it impossible to obtain a stable point of force. While the guardrail maintains a reasonable height, the rotation of the rotating cylinder 203 can significantly increase the difficulty of climbing and prevent climbers from climbing over the guardrail.

[0039] Example 3

[0040] Reference Figure 1 This is the third embodiment of the present invention. Unlike the previous embodiment, the support member includes a column 101, a rotating sleeve 102, and an ear plate 103. The rotating sleeve 102 and the ear plate 103 are each provided with four sets. The four sets of rotating sleeves 102 are rotatably sleeved on the outside of the column 101. The four sets of ear plates 103 are respectively fixedly connected to the side walls of the four sets of rotating sleeves 102. Two sets of protective frames 104 are alternately arranged between the three sets of support members. The two sets of protective frames 104 have four sets of through holes 104a on both sides of their frames. The four sets of through holes 104a are respectively located on the same horizontal line as the four sets of ear plates 103 of the support member. The two sets of protective frames 104 are respectively detachably connected to two sets of ear plates 103 of the adjacent support member on both sides.

[0041] Furthermore, the ear plate 103 is fitted with a locking nut 106 and a connecting bolt 105. The locking nut 106 passes through the ear plate 103 and the corresponding through hole 104a and is threadedly connected to the connecting bolt 105. The protective frame 104 is detachably connected to the ear plate 103 through the locking nut 106 and the connecting bolt 105.

[0042] Furthermore, the surfaces of the column 101, rotating sleeve 102, ear plate 103, and protective frame 104 are all coated with anti-corrosion paint.

[0043] Furthermore, a mounting plate is fixed to the bottom of the column 101, and the mounting plate has three sets of mounting holes equidistantly spaced around the column 101.

[0044] It should be noted that the surfaces of the column 101, rotating sleeve 102, ear plate 103 and protective frame 104 are all coated with anti-corrosion paint. The anti-corrosion paint is used to prevent rust and also enhances the appearance of the device. A mounting plate is fixed to the bottom of the column 101. The mounting plate has three sets of mounting holes equidistantly around the column 101. The mounting plate is used to facilitate fixing the position of the column 101.

[0045] In use, the protection range of the device can be increased by increasing the number of protective frames 104 and support members. When adding protective frames 104, the new protective frames 104 are connected to the corresponding sets of ear plates 103 of the support members using connecting bolts 105 and locking nuts 106. The position of the support members can be moved, such as... Figure 1 The protection range of the device can be adjusted as needed.

[0046] In summary, a safety guardrail, while providing safety protection, prevents climbers from obtaining a stable point of leverage through the setting of the rotating cylinder 203. While maintaining a reasonable height, the rotation of the rotating cylinder 203 significantly increases the difficulty of climbing and hinders climbers from climbing over the guardrail.

[0047] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
