Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, and in particular to a guardrail for municipal engineering projects to prevent tipping. Background Technology

[0002] In the construction and maintenance of municipal engineering projects, guardrails serve as crucial facilities for ensuring the safety of construction sites and isolating dangerous areas, and their stability and convenience are of paramount importance. Traditional municipal guardrails typically rely solely on bottom fixing devices for stability, making them prone to tipping over under complex terrain or strong external impacts, thus failing to effectively guarantee on-site safety.

[0003] To improve the anti-tipping performance of guardrails, some guardrails have begun to be equipped with auxiliary supports. However, most existing guardrails with auxiliary supports use traditional bolt-fixing methods. The auxiliary supports require repeated disassembly and reassembly of multiple bolts during storage and use, making the operation extremely cumbersome and consuming a significant amount of time and manpower. Given the varied usage scenarios of guardrails, this inconvenient storage and use method severely impacts construction efficiency and fails to meet the needs for rapid deployment and flexible adjustment. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a protective railing for municipal engineering to prevent tipping. This can solve the problem that most existing protective railings with auxiliary supports use the traditional bolt fixing method, which requires repeated disassembly and installation of multiple bolts when storing and using the auxiliary supports, making the operation extremely cumbersome.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective railing for municipal engineering to prevent tipping, comprising two bases, each base having two first threaded grooves inside, a protective frame fixedly connected to the top of the two bases, multiple protective rods fixedly installed inside the protective frame, two storage slots on one side of the protective frame, auxiliary brackets rotatably connected inside the two storage slots, circular slots on opposite ends of the two auxiliary brackets, a limiting groove on one side of the inner wall of each of the two storage slots, a fixing component inside each of the two limiting grooves, the fixing component including a pull rod, the outer surface of the pull rod slidably connected to the inner wall of the limiting groove, and one end of the pull rod being a spherical end.

[0006] Preferably, a limit block is fixedly connected to the outer surface of the pull rod, and a pressure spring is fixedly connected to one side of the limit block.

[0007] Preferably, the inner wall of the limiting groove is provided with a limiting groove, the inner wall of the limiting groove is slidably connected to the outer surface of the limiting block, and the end of the pressure spring away from the limiting block is fixedly connected to the inner wall of the limiting groove.

[0008] Preferably, there are two fixing components, both of which have the same structure and are respectively disposed inside the two limiting slides.

[0009] Preferably, the opposing spherical ends of the two pull rods are slidably connected to the inner wall of the corresponding circular slot.

[0010] Preferably, both bases have mating grooves inside, and the inner walls of the two mating grooves are slidably adapted to the outer surfaces of the two auxiliary supports.

[0011] Preferably, each of the two bases has a second threaded groove at its opposite ends, and a fixing bolt is threaded into the interior of each of the two second threaded grooves. One end of each fixing bolt is adapted to one end of a circular slot.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The anti-tipping guardrail used in this municipal engineering project involves one side of the auxiliary bracket pressing against the spherical end of the tie rod. The tie rod then briefly retracts into the limiting groove. Next, when the inside of the circular slot aligns with the limiting groove, the spherical end of the tie rod enters the circular slot, thus storing and fixing the auxiliary bracket. This allows for flexible storage and use of the auxiliary bracket, overcoming the inconvenience of storing and using traditional bolt-type auxiliary brackets, thereby improving the usability of the guardrail.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a protective railing for municipal engineering to prevent tipping, including two bases 1, each base 1 having two first threaded grooves 8 inside, a protective frame 2 fixedly connected to the top of the two bases 1, multiple protective rods 3 fixedly installed inside the protective frame 2, two storage slots 4 on one side of the protective frame 2, auxiliary brackets 5 rotatably connected inside the two storage slots 4, circular slots 15 on opposite ends of the two auxiliary brackets 5, a limiting groove 6 on one side of the inner wall of each of the two storage slots 4, and a fixing component inside each of the two limiting grooves 6, the fixing component including a pull rod 7, the outer surface of the pull rod 7 slidably connected to the inner wall of the limiting groove 6, and one end of the pull rod 7 being a spherical end.

[0026] Furthermore, a limit block 13 is fixedly connected to the outer surface of the pull rod 7, and a pressure spring 14 is fixedly connected to one side of the limit block 13.

[0027] Furthermore, a limiting groove 12 is formed on the inner wall of the limiting groove 6. The inner wall of the limiting groove 12 is slidably connected to the outer surface of the limiting block 13. The end of the pressure spring 14 away from the limiting block 13 is fixedly connected to the inner wall of the limiting groove 12.

[0028] Furthermore, there are two fixing components, both of which have the same structure and are respectively set inside the two limiting slides 6.

[0029] Furthermore, the spherical ends of the two pull rods 7 are slidably connected to the inner walls of the corresponding circular slots 15.

[0030] Furthermore, both bases 1 have mating grooves 9 inside, and the inner walls of the two mating grooves 9 are respectively slidably adapted to the outer surfaces of the two auxiliary supports 5.

[0031] Furthermore, each of the two bases 1 has a second threaded groove 10 at its opposite ends, and each of the two second threaded grooves 10 is threaded with a fixing bolt 11. One end of each fixing bolt 11 is adapted to one end of a circular slot 15.

[0032] Furthermore, during the installation of the guardrail, the guardrail is first fixed to the ground with matching bolts using the first threaded groove 8 inside the base 1, initially ensuring the stability of the guardrail. If the site environment is complex and the anti-tipping ability of the guardrail needs to be further enhanced, the pull rod 7 can be pulled. Then, the spherical end of the pull rod 7 will disengage from the interior of the circular slot 15. Next, the auxiliary bracket 5 in the storage slot 4 can be rotated out. The auxiliary bracket 5 rotates around the rotation connection point of the storage slot 4, and the rotated end enters the interior of the docking slot 9, so that the circular slot 15 is aligned with the second threaded groove 10. Then, the fixing bolt 11 is screwed into the interior of the circular slot 15, so that one end of the auxiliary bracket 5 can be fixed inside the docking slot 9. Then, the auxiliary bracket 5 and the pull rod 7 form a triangular support structure, which enables the protective frame 2 to have strong stability, making the guardrail less prone to tipping over.

[0033] Furthermore, when the protective bracket is not in use, the fixing bolt 11 is disengaged from the inside of the circular slot 15. Then, the auxiliary bracket 5 is rotated into the inside of the storage slot 4. Then, one side of the auxiliary bracket 5 will press against the spherical end of the pull rod 7. Then, the pull rod 7 will briefly retract into the inside of the limiting slide groove 6. Then, when the inside of the circular slot 15 is aligned with the limiting slide groove 6, the spherical end of the pull rod 7 will enter the inside of the circular slot 15, thereby storing and fixing the auxiliary bracket 5. This allows the auxiliary bracket to be flexibly stored and used, solving the shortcomings of traditional bolt-type auxiliary brackets that are inconvenient to store and use, thus making the guardrail more usable.

[0034] Furthermore, during the daily use of the guardrail, the protective frame 2 and multiple guardrails 3 form a protective structure to prevent unauthorized personnel from entering the specific area. When the guardrail is impacted by an external force, the protective frame 2 will transfer the impact force to the triangular structure formed by the base 1 and the auxiliary support 5, so that the base 1 and the auxiliary support 5 can jointly bear and disperse the impact force, preventing the guardrail from tipping over due to uneven force distribution.

[0035] Structural Description:

[0036] Base 1: It is the basic support component of the guardrail. It has a first threaded groove 8 inside, which is used to fix it to the ground by matching bolts, so as to provide initial stability for the guardrail.

[0037] First threaded groove 8: Located inside the base 1, it is used to fix the guardrail to the ground with matching bolts, ensuring the initial installation stability of the guardrail.

[0038] Protective frame 2: Fixed to the top of the two bases 1, with multiple protective rods 3 installed inside to form a protective area, preventing unauthorized personnel from entering the specific area. At the same time, storage slots 4 are opened on the side of the protective frame 2 for storing and rotating auxiliary brackets 5.

[0039] Protective rod 3: It is fixedly installed inside the protective frame 2 and together with the protective frame 2, it forms a protective structure to prevent people from entering the municipal engineering area at will.

[0040] Storage slot 4: Provides storage space for auxiliary support 5 and serves as a fulcrum for the rotation of auxiliary support 5.

[0041] Auxiliary bracket 5: When the site environment is complex and it is necessary to enhance the anti-tipping ability of the guardrail, the auxiliary bracket 5 can be rotated out. The opposite ends of the auxiliary bracket 5 are provided with circular slots 15, which cooperate with the ball end of the tie rod 7 and the fixing bolt 11 to achieve positioning and fixation. After being rotated out, one end enters the docking slot 9, forming a triangular support structure with the base 1 and the tie rod 7 to enhance the stability of the guardrail. When not in use, it can be rotated and stored in the storage slot 4.

[0042] Circular slot 15: Located at the opposite end of the auxiliary bracket 5, its inner wall is slidably connected to the spherical end of the pull rod 7, and with the fixing bolt 11, the auxiliary bracket 5 is fixed.

[0043] Limiting groove 6: It is opened on one side of the inner wall of the storage groove 4, and a fixing component is set inside to provide a sliding track for the pull rod 7. Through cooperation with the pull rod 7, it positions the auxiliary bracket 5 for storage and use.

[0044] Fixing component: Composed of pull rod 7, limit block 13 and pressure spring 14, installed in limit slide groove 6 to achieve convenient fixing and storage of auxiliary bracket 5.

[0045] Pull rod 7: The outer surface is slidably connected to the inner wall of the limiting slide groove 6. One end is a spherical end, which is slidably connected to the inner wall of the circular slot 15. By sliding in the limiting slide groove 6, the auxiliary bracket 5 can be fixed and released. The outer surface is fixedly connected to the limiting block 13, which works in conjunction with the pressure spring 14.

[0046] Limiting block 13: controls the sliding range of the pull rod 7, and under the action of the pressure spring 14, makes the spherical end of the pull rod 7 automatically insert into the circular slot 15.

[0047] Pressure spring 14: One end is connected to the limiting block 13, and the other end is fixed to the inner wall of the limiting groove 12. It provides elastic force to the pull rod 7, so that its spherical end can automatically enter or leave the circular slot 15, realizing the convenient fixing and storage of the auxiliary bracket 5.

[0048] Limiting groove 12: It is formed on the inner wall of the limiting slide groove 6. Its inner wall is slidably connected to the outer surface of the limiting block 13, providing a sliding track for the limiting block 13, limiting its range of motion, and ensuring the normal operation of the fixing component.

[0049] The docking groove 9 is located inside the base 1. Its inner wall is slidably adapted to the outer surface of the auxiliary bracket 5. After the auxiliary bracket 5 is rotated out, one end can enter the docking groove 9. With the help of the fixing bolt 11, the auxiliary bracket 5 is fixed on the base 1.

[0050] The second threaded groove 10 is located on one side of the base 1 and has an internal threaded connection to the fixing bolt 11. The fixing bolt 11 is screwed into the circular slot 15 through the second threaded groove 10 to further fix the auxiliary bracket 5.

[0051] Fixing bolt 11: By tightening or loosening the bolt, the auxiliary support 5 can be fixed and released.
