Description

Technical Field

[0001] This utility model relates to the field of construction guardrail technology, specifically a construction guardrail that can be quickly disassembled and assembled. Background Technology

[0002] Construction engineering refers to the physical engineering project established by the construction of various buildings and ancillary facilities and the installation of supporting lines, pipelines and equipment; construction guardrails are a very common auxiliary component in the construction process. They are safety facilities set up around the construction site. Construction guardrails are usually made of materials such as steel pipes, plastics and nylons, and are generally about 1.2 meters high. They are usually yellow or white in color and have obvious warning signs and safety slogans. Construction guardrails are also called construction enclosures.

[0003] During construction, to reduce safety accidents, construction guardrails are often used. The base is first moved to the perimeter of the construction site, then the guardrail is inserted into the fixing frame. Multiple guardrails are then used to enclose the construction site, providing isolation and warning to prevent personnel and vehicles from accidentally entering dangerous areas. However, construction guardrails are typically installed using multiple sets of bolts, which is cumbersome, requiring repeated turning of the bolts and potentially damaging the guardrail's outer shell. Furthermore, subsequent disassembly requires turning the bolts again, making it inconvenient and affecting the guardrail's usability. Utility Model Content

[0004] The purpose of this utility model is to provide a construction guardrail that can be quickly disassembled and assembled, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a construction guardrail that can be quickly disassembled and assembled, comprising a base, a fixing frame, and a protective barrier. The fixing frame is welded to both sides of the top of the base, and the protective barrier is slidably connected inside the fixing frame. A fixing mechanism is provided on the outer wall of the fixing frame. The fixing mechanism includes a motor box, a drive motor, a bidirectional threaded rod, a threaded seat, an extension plate, a guide rod, a guide plate, a fixing rod, a limit seat, and a fixing seat. The motor box is connected to the middle of the bottom end of the fixing frame, and the drive motor is installed inside the motor box. The output end of the drive motor is connected to the bidirectional threaded rod.

[0006] Preferably, the top end of the bidirectional threaded rod is connected to an extension plate via a bearing seat, and threaded seats are threadedly connected to both sides of the outer wall of the bidirectional threaded rod.

[0007] Preferably, guide rods are rotatably connected to both sides of the outer wall of the threaded seat, and a guide plate is rotatably connected to the side of the guide rods away from the threaded seat.

[0008] Preferably, a fixing rod is welded to the outer wall of the guide plate on the side away from the threaded seat, and a limit seat is slidably connected to the outer wall of the fixing rod.

[0009] Preferably, the fixing rod is connected to a fixing seat through a fixing hole, and the outer wall of the fixing seat is welded to the protective fence.

[0010] Preferably, the outer wall of the protective fence is provided with an auxiliary mechanism, which includes a slide rail, a warning plate, a limit rod, a limit plate, a limit pin, a spring, a transmission rod, and a fixing pin. The middle part of the outer wall of the protective fence is welded with a slide rail.

[0011] Preferably, a warning plate is slidably connected inside the slide rail, and a limit rod is connected to the bottom end of the slide rail through a limit cavity.

[0012] Preferably, a limiting plate is welded to one side of the outer wall of the limiting rod, and a limiting pin is slidably connected to the top of the limiting plate.

[0013] Preferably, a spring is sleeved on the outer wall of the limiting pin, and fixing pins are connected to both sides of the bottom end of the protective fence.

[0014] Preferably, a transmission rod is rotatably connected to the outer wall of the fixing pin, and the limiting plate, the limiting pin and the spring form an elastic telescopic mechanism.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this quick-disassembly construction guardrail, the fixing mechanism can be used to remove the fixing of the protective fence, thus eliminating the need to repeatedly rotate multiple sets of bolts. This allows for automatic removal of the protective fence, facilitating disassembly and saving time. The auxiliary mechanism removes the limit on the warning plate, allowing it to move out from under the slide rail. Simply rotating the transmission rod is sufficient to replace the warning plate, making it easy to replace the warning plate during the use of the construction guardrail.

[0016] 1. During construction, in order to reduce the occurrence of safety accidents, when construction guardrails are needed, the drive motor is first started to drive the double-threaded rod to rotate. Then, the double-threaded rod causes the threaded seat to move away from each other. After that, the movement of the threaded seat drives the guide rod to rotate, which causes the guide plate to disengage the fixed rod from the fixed seat, thereby canceling the fixation of the protective fence. Thus, the fixation of the protective fence can be automatically canceled without repeatedly turning multiple sets of bolts, which makes it convenient for people to disassemble the protective fence, saving time. Therefore, the construction guardrail can be used to facilitate quick assembly and disassembly.

[0017] 2. During construction, to reduce the occurrence of safety accidents, when construction guardrails are needed as an auxiliary measure, first rotate the transmission rod to press the limiting plate, causing the limiting plate to move the limiting rod away from under the warning plate, thereby canceling the limitation on the warning plate. At this time, the warning plate moves out from under the slide rail. Then, move the warning plate to be replaced into the slide rail. Then, simply rotate the transmission rod to complete the replacement of the warning plate. This makes it convenient to replace the warning plate when using construction guardrails.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-7 This utility model provides a technical solution: a construction guardrail that can be quickly disassembled and assembled, including a base 1, a fixing frame 2, and a protective barrier 3. The fixing frame 2 is welded to both sides of the top of the base 1, and the protective barrier 3 is slidably connected inside the fixing frame 2. A fixing mechanism 4 is provided on the outer wall of the fixing frame 2. The fixing mechanism 4 includes a motor housing 401, a drive motor 402, a bidirectional threaded rod 403, a threaded seat 404, an extension plate 405, a guide rod 406, a guide plate 407, a fixing rod 408, a limiting seat 409, and a fixing seat 410. The motor housing 401 is connected to the middle of the bottom end of the fixing frame 2, and the drive motor 402 is installed inside the motor housing 401. The output end of the drive motor 402 is connected to the bidirectional threaded rod 403. The top end of the bidirectional threaded rod 403 is connected to a bearing seat. The device includes an extension plate 405, and threaded seats 404 are threadedly connected to both sides of the outer wall of the bidirectional threaded rod 403. Guide rods 406 are rotatably connected to both sides of the outer wall of the threaded seat 404, and a guide plate 407 is rotatably connected to the side of the guide rod 406 away from the threaded seat 404. A fixing rod 408 is welded to the side of the outer wall of the guide plate 407 away from the threaded seat 404, and a limit seat 409 is slidably connected to the outer wall of the fixing rod 408. A fixing seat 410 is connected to the fixing rod 408 through a fixing hole, and the outer wall of the fixing seat 410 is welded to the protective enclosure 3. The limit seat 409 is welded to the protective enclosure 3. The fixing rods 408 are evenly distributed on the guide plate 407, and the guide plate 407 is symmetrically distributed about the vertical midline of the protective enclosure 3. The outer wall of the extension plate 405 is welded to the protective enclosure 3.

[0031] In specific implementation, during the construction process, in order to reduce the occurrence of safety accidents, when construction guardrails are needed as an auxiliary, and due to different conditions at the construction site, it is necessary to disassemble the construction guardrails and install them at other locations, the drive motor 402 in the motor box 401 is started first. Because the output end of the drive motor 402 is connected to the bidirectional threaded rod 403, the start of the drive motor 402 causes the bidirectional threaded rod 403 to rotate along the extension plate 405. Since the bidirectional threaded rod 403 and the threaded seat 404 are threadedly connected, the rotation of the bidirectional threaded rod 403 causes the threaded seat 404 to move away from each other. Since the threaded seat 404 and the guide rod 406 are rotatably connected, the movement of the threaded seat 404 drives the guide rod 406 to rotate.

[0032] At this time, the included angle between the guide rod 406 and the bidirectional threaded rod 403 changes, which in turn generates a pulling force on the guide plate 407, causing the guide plate 407 to move towards the threaded seat 404. Since the guide plate 407 is in contact with the fixed rod 408, the movement of the guide plate 407 causes the fixed rod 408 to move along the limiting seat 409 until the limiting seat 409 is disengaged from the fixed seat 410, thereby canceling the fixation of the protective fence 3. Thus, the fixation of the protective fence 3 can be automatically canceled without repeatedly turning multiple sets of bolts, which makes it convenient for people to disassemble the protective fence 3, saving time. Therefore, it plays a role in facilitating quick assembly and disassembly when the construction guardrail is used.

[0033] When it is necessary to install the protective fence 3, simply insert the protective fence 3 into the fixed frame 2, then start the drive motor 402 to move the threaded seat 404 closer to each other, thereby causing the guide plate 407 to move away from the bidirectional threaded rod 403 until the fixed rod 408 is in contact with the fixed seat 410, thereby limiting the protective fence 3 and preventing it from moving at will.

[0034] See Figure 1 , Figure 2 , Figure 4 , Figure 8 , Figure 9 and Figure 10 It is known that the outer wall of the protective fence 3 is provided with an auxiliary mechanism 5, and the auxiliary mechanism 5 includes a slide rail 501, a warning plate 502, a limiting rod 503, a limiting plate 504, a limiting pin 505, a spring 506, a transmission rod 507, and a fixing pin 508. The slide rail 501 is welded to the middle of the outer wall of the protective fence 3; the warning plate 502 is slidably connected inside the slide rail 501, and the bottom end of the slide rail 501 is connected to the limiting rod 503 through a limiting cavity; a limiting plate 504 is welded to one side of the outer wall of the limiting rod 503, and the limiting... The top of the plate 504 is slidably connected to a limiting pin 505; a spring 506 is sleeved on the outer wall of the limiting pin 505; and fixing pins 508 are connected to both sides of the bottom of the protective enclosure 3; a transmission rod 507 is rotatably connected to the outer wall of the fixing pin 508; the limiting plate 504, the limiting pin 505 and the spring 506 form an elastic telescopic mechanism; the limiting pin 505 is connected to the protective enclosure 3 through an extension block; the slide rail 501 is slidably connected to the limiting rod 503; and the fixing pin 508 is fixedly connected to the protective enclosure 3.

[0035] In practice, during construction, when construction railings are needed to reduce safety accidents, and when warning signs on the railings need to be replaced as the usage time increases, the transmission rod 507 and the fixing pin 508 are rotatably connected. First, the transmission rod 507 is manually rotated so that it rotates along the fixing pin 508. Then, the top of the rotating transmission rod 507 presses against the limiting plate 504, causing the limiting plate 504 to move along the limiting rod 503. Since the limiting plate 504 and the limiting rod 503 are in contact, the movement of the limiting plate 504 drives the limiting rod 503 to move together. When the limiting plate 504 moves, it presses against the spring 506, causing the spring 506 to deform until the limiting rod 503 is removed from under the warning plate 502.

[0036] Then the limit on warning plate 502 is removed. At this time, warning plate 502 moves downward under its own weight until it moves out from under slide rail 501. Then the warning plate 502 to be replaced is moved into slide rail 501. After that, spring 506 resets and drives limit rod 503 to return to its position. At this time, the limit rod 503 provides auxiliary support for warning plate 502 to prevent it from moving downward. Then, simply rotate transmission rod 507 to complete the replacement of warning plate 502. Thus, when using construction guardrail, it facilitates the replacement of warning plate 502.

[0037] In summary, when using this quick-assembly and disassembly construction guardrail, the base 1 is first moved to the perimeter of the construction site, then the protective fence 3 is inserted into the fixing frame 2, and then the construction site is enclosed by the cooperation of multiple protective fences 3, thereby achieving the effect of isolation and warning, preventing personnel and vehicles from accidentally entering the dangerous area. This is existing technology and will not be elaborated on here. The fixing mechanism 4 cancels the fixing of the protective fence 3, thus eliminating the need to repeatedly turn multiple sets of bolts, and the fixing of the protective fence 3 can be automatically canceled, which facilitates the disassembly of the protective fence 3 and saves time. The auxiliary mechanism 5 cancels the limit of the warning plate 502. At this time, the warning plate 502 moves out from under the slide rail 501, and then the replacement of the warning plate 502 can be completed by simply turning the transmission rod 507. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
