Description

Technical Field

[0001] The present application relates to the technical field of municipal construction safety protection equipment, and in particular to a municipal construction guardrail. Background Art

[0002] Municipal construction guardrails play a vital role in municipal engineering projects, effectively preventing pedestrians from straying into construction areas and ensuring safety on construction sites. With the accelerated pace of urbanization and the increasing frequency of various municipal projects, the demand for construction guardrails is also growing. This requires not only that construction guardrails provide excellent protection but also that they are highly convenient and can be quickly installed and removed to accommodate the frequently changing layout requirements of municipal projects.

[0003] Currently, in the field of municipal construction guardrails, in order to meet the protection needs of construction sites, the following solutions are commonly used. One is the traditional fixed guardrail, which is directly fixed to the ground in the construction area by welding or bolts. Although this type of guardrail provides relatively stable protection, its disassembly and assembly process is cumbersome, consuming a lot of time and manpower, and is difficult to adapt to the frequently changing needs of municipal engineering projects. Another solution is to use portable guardrails, which are designed to be detachable and connected through modular design. For example, on-site assembly using connectors improves convenience to a certain extent, but in actual operation, there is a problem of loose structural connections. In addition, there are guardrail solutions using telescopic rods or folding fence designs. This design can improve the transportation convenience of the guardrail to a certain extent, but it still faces problems such as complex on-site installation steps and poor stability after installation.

[0004] Although the above-mentioned existing municipal construction guardrails meet the protection needs to a certain extent, they still have many shortcomings in terms of portability and ease of installation and disassembly, especially in terms of rapid deployment and recovery, which have problems such as complex installation and long time consumption. Utility Model Content

[0005] The purpose of this application is to overcome the above technical problems and provide a municipal construction guardrail.

[0006] A municipal construction guardrail, comprising a column and a guardrail;

[0007] The barrier comprises:

[0008] Telescopic blocking part;

[0009] Connecting plates are respectively connected to the two ends of the telescopic blocking part, and the opposite sides of the connecting plates are formed with plug plates;

[0010] The column comprises:

[0011] The support body is vertically arranged, and opposite sides of the peripheral wall of the support body are formed with slots for inserting the plug board;

[0012] The locking block slides vertically on the upper end of the support body, and the downward sliding of the locking block can prevent the plug-in board from leaving the slot.

[0013] By adopting this technical solution, the municipal construction guardrail features quick installation and removal, making it easy to carry. Specifically, the slots on the columns and the inserts on the guardrail connecting plate allow for quick connection between the guardrail and the columns. The vertical sliding design of the locking block prevents the inserts from being removed from the slot once inserted, ensuring a secure and reliable guardrail installation.

[0014] Preferably, a locking slot is formed on the upper end of the plug board; and a locking column is vertically formed at the position of each locking block corresponding to each slot;

[0015] The vertical movement of the locking block can enable the locking cylinder to be inserted into or withdrawn from the locking slot.

[0016] By adopting the above technical solution, the vertical movement of the locking block can enable the locking column to be inserted into or exit the locking slot on the upper end of the plug plate, thereby achieving a stable and convenient connection and separation between the plug plate and the column slot, thereby improving the overall assembly efficiency and ease of use of the municipal construction guardrail.

[0017] Preferably, the column further comprises:

[0018] An elastic holding member is vertically arranged on the support body, one end of which is fixed to the support body, and the other end of which is fixed to the locking block;

[0019] The elastic holding member holds the locking block, and can keep the locking column inserted into the locking groove.

[0020] By adopting the above technical solution, the setting of the elastic holding member can ensure that the locking block keeps the lock column inserted into the locking groove through the action of the elastic holding member when there is no external force, thereby achieving a stable connection between the guardrail and the column, and improving the overall stability and reliability of the municipal construction guardrail.

[0021] Preferably, a slide groove is vertically formed on the upper end of the support body, the slide groove is connected to the slot, and the locking block slides in the slide groove;

[0024] The end of the limiting bolt is inserted into the limiting groove to limit the locking block from being separated from the sliding groove.

[0025] By adopting this technical solution, the vertically formed sliding groove on the upper end of the support body allows the locking block to slide within the groove and connect with the slot, thereby locking and unlocking the plug plate. A vertical limiting groove on the peripheral wall of the locking block cooperates with a limiting bolt threadedly connected to the peripheral wall of the support body. When the limiting bolt end is inserted into the limiting groove, it effectively prevents the locking block from disengaging from the sliding groove, thereby ensuring the stability of the locking block and the locking effect.

[0026] Preferably, an emission groove is formed on the opposite sides of the peripheral wall of the locking block; a rotating column is formed in the locking block, and a laser emitter is provided in the rotating column;

[0027] As the rotating column rotates, the emitting end of the laser emitter can be driven to correspond to each emitting slot in sequence.

[0028] By adopting the above technical solution, emission grooves are formed on the opposite sides of the peripheral wall of the locking block, a rotating column is formed inside the locking block, and a laser emitter is arranged inside the rotating column. As the rotating column rotates, the emitting end of the laser emitter can be driven to correspond to each emission groove in turn, thereby realizing multi-directional emission of laser warning signals and improving the warning effect of construction guardrails at night or in low visibility environments.

[0029] Preferably, a rotary groove is vertically opened on the upper end of the locking block, and the rotary groove is connected to each emission groove;

[0030] The rotating column is arranged in the rotating groove;

The rotary column is arranged in the rotary groove, and the top cover is fixed to the upper end of the rotary column and the outer edge extends out of the outer edge of the locking block, so that the emitting end of the laser emitter can correspond to each emission slot in sequence as the rotary column rotates, thereby realizing multi-directional emission of laser signals.

[0034] Preferably, the telescopic barrier is a scissor-type folding fence.

[0035] By adopting the above technical solution, the setting of the scissor-type folding fence enables the municipal construction guardrail to have good folding and storage functions, which is convenient for carrying and transportation. At the same time, it is quick to install and disassemble, thereby improving on-site construction efficiency.

[0036] Preferably, the lower side of the end of the scissor-type folding fence is hinged to a connecting plate; the connecting plate is rotatably connected to a vertically arranged distance-adjusting bolt;

[0037] The upper side of the end of the scissor-type folding fence is rotatably connected to a movable shaft;

[0038] The movable shaft is threadedly connected to the distance adjusting bolt.

[0039] By adopting the above technical solution, the lower side of the end of the scissors-type folding fence is hinged to the connecting plate, the connecting plate is rotatably connected to a vertically arranged distance-adjusting bolt, and the upper side of the end of the scissors-type folding fence is rotatably connected to a movable shaft, which is threadedly connected to the distance-adjusting bolt, thereby realizing convenient adjustment of the fence height and improving the adaptability and ease of use of the construction guardrail.

[0040] Preferably, the telescopic barrier is a rolling curtain type telescopic enclosure.

[0041] By adopting the above technical solution, the roller shutter telescopic fence can be easily and quickly unfolded and retracted, effectively improving the convenience and efficiency of the municipal construction guardrail during use.

[0043] Two scrolls are rotatably arranged in the shell;

[0044] Two coil springs are fixed between the reel and the housing respectively;

[0045] The ends of the rolling blind are respectively fixed to the rolling shaft and extend out of the shell.

[0046] By adopting the above technical solution, the retractable roller shutter enclosure can be extended and retracted conveniently and quickly, improving the overall portability and ease of use of the municipal construction guardrail. Specifically, the two shells are vertically fixed to the connecting plate, and the two reels are rotatably arranged within the shells and fixedly connected to the two coil springs. The ends of the roller shutter are respectively fixed to the reels and extend out of the shell, allowing the roller shutter to automatically retract into the shell under the action of the coil springs, simplifying the installation and removal process and facilitating portability.

[0047] In summary, this application includes at least one of the following beneficial technical effects:

[0057] The following will be combined with the Figure 1-3 The technical solutions in the embodiments of the present invention are clearly and completely described. The described embodiments are only possible technical implementations of the present invention and do not represent all possible implementations. Those skilled in the art can fully combine the embodiments of the present invention to derive other embodiments without inventive work, and these embodiments are also within the scope of protection of the present invention.

[0058] The inventors of this application have discovered that municipal construction guardrails play an important role in municipal engineering projects, but existing municipal construction guardrails have many shortcomings in terms of portability and ease of installation and disassembly. For example, traditional fixed guardrails are cumbersome to install and disassemble, portable guardrails have weak structural connections, guardrails with telescopic rods or folding fences have complex on-site installation steps, and poor stability after installation. To this end, this application primarily adopts the following solution to achieve the effect of convenient disassembly and portability. The following further describes this application in detail. Example 1

[0059] The embodiment of the present application provides a municipal construction guardrail, comprising a column 1 and a telescopic barrier 2. The telescopic barrier 2 comprises a telescopic blocking portion 21 and a connecting plate 22.

[0060] The telescopic barrier 21 is a scissor-type folding fence, which is composed of a plurality of cross-arranged rods 211. The rods 211 are made of a lightweight and high-strength aluminum alloy material to reduce the weight of the entire guardrail while ensuring that it has sufficient strength. The rods 211 are in the shape of a slender column, and their cross-section can be circular or square. The rods 211 are connected by hinges. The design of the hinges allows the rods 211 to be flexibly folded and unfolded, thereby realizing the telescopic function of the fence. The hinge is made of stainless steel, which has good wear resistance and corrosion resistance, ensuring the reliability of the hinge during long-term use.

[0061] The connecting plates 22 are respectively connected to both ends of the telescopic blocking portion 21 . The connecting plates 22 are made of a solid steel plate and are rectangular in shape.

[0062] A rod 211 at the lower end of the telescopic barrier 21 is hinged to the lower side of the connecting plate 22. A vertical slot 221 is formed in the upper portion of the connecting plate 22, near the telescopic barrier. A movable shaft 212 is hinged to the rod 211 at the upper end of the telescopic barrier 21. The movable shaft 212 is inserted into the vertical slot 221 and slides vertically within the slot 221. A vertically arranged distance-adjusting bolt 222 is rotatably connected to the connecting plate 22 corresponding to the position of the vertical slot 221. The distance-adjusting bolt 222 passes vertically through the vertical slot 221. The movable shaft 212 is threadedly connected to the distance-adjusting bolt 222. Rotating the distance-adjusting bolt 222 drives the movable shaft 212 to move vertically along the vertical slot 221, thereby adjusting the position of the upper rod 211 of the telescopic barrier 21 and, in turn, the horizontal distance of the telescopic barrier 21 to meet different operational requirements.

[0063] The column 1 includes a support body 11, a locking block 12 and an elastic pull member 13. The support body 11 is a vertically arranged columnar structure made of metal material, such as high-strength steel, to ensure that it has sufficient load-bearing capacity and stability. The cross-section of the support body 11 can be cylindrical or square. In this embodiment, a square is used as an example, and its height can be adjusted according to actual needs. The surface of the support body 11 is treated with rust prevention to extend its service life. Slots 111 are formed on the opposite sides of the peripheral wall of the support body 11, that is, the peripheral wall of the support body 11 is formed with 4 slots 111, which are 90° apart from each other. To meet different splicing requirements.

[0064] Insert plates 223 are formed on the sides of the connecting plates 22 at both ends of the telescopic blocking portion 21. These plates are made of the same steel plate as the connecting plates 22. One end of the insert plate 223 is securely fixed to the connecting plate 22 by welding, while the other end is free. The insert plates 223 are rectangular in shape to ensure they can be securely inserted into the slots 111.

[0065] A sliding groove 112 is vertically provided at the upper end of the support body 11, and the lower end of the sliding groove 112 is connected to the slot 111. A locking block 12 is vertically provided in the sliding groove 112. The shape and size of the locking block 12 match the sliding structure on the support body 11, so that it can slide up and down smoothly on the support body 11.

[0066] In order to limit the moving distance of the locking block 12, a limiting groove 121 is vertically opened on the peripheral wall of the locking block 12, and a horizontally arranged limiting bolt 113 is threadedly connected on the peripheral wall of the support body 11. By rotating the limiting bolt 113, its end can be inserted into the limiting groove 121. When the locking block 12 slides, the end of the limiting bolt 113 slides in the limiting groove 121 to limit the vertical moving distance of the locking block 12.

[0067] The locking block 12 has a locking column 122 formed vertically at the position corresponding to each slot 111, and the insert plate 223 has a locking groove 224 formed at the position corresponding to each lock column 122. When the locking block 12 moves vertically, the locking column 122 can be accurately inserted into or exited from the locking groove 224, thereby locking or unlocking the insert plate 223.

[0068] An elastic holding member 13 is vertically disposed in the middle of the support body 11. In this embodiment, the elastic holding member 13 is a spring, one end of which is fixed to the support body 11, and the other end of which is fixed to the locking block 12. The spring has sufficient tension to hold the locking block 12 in place, thereby ensuring that the locking block 12 remains in the locked position and improving locking stability.

[0069] The locking block 12 also has launch slots 123 formed on opposite sides of its perimeter wall. Specifically, the perimeter wall of the locking block 12 is formed with four launch slots 123 that connect to each other perpendicularly. A vertical rotation slot 124 is formed at the upper end of the locking block 12. Rotation slot 124 communicates with each launch slot 123. A rotation post 14 is coaxially disposed within rotation slot 124 and coaxially rotates within rotation slot 124. A mounting slot 141 is formed within the rotation post 14 corresponding to the launch slot 123. A laser emitter 15 is mounted within mounting slot 141. As rotation post 14 rotates, it drives the emitting end of the laser emitter 15 to correspond to each launch slot 123 in sequence. A top cover 142 is fixed to the upper end of the locking block 12, the outer edge of which extends beyond the outer edge of the locking block 12.

[0070] By setting up the laser emitter 15, at night or in low visibility environments, the top cover 142 can drive the rotary column 14 to rotate, thereby driving each laser emitter 15 to align with the corresponding emission slot 123 to emit a laser beam to alert passers-by, thereby improving the warning effect of the construction guardrail at night or in low visibility environments.

[0071] The working principle of this embodiment is as follows: During installation, the insert plates 223 on the connecting plates 22 at both ends of the telescopic blocking portion 21 are inserted into the slots 111 of the support body 11. The locking block 12 is then slid downward so that the locking post 122 on the locking block 12 is inserted into the locking groove 224 on the insert plates 223, thereby locking the insert plates 223 and securing the barrier 2 to the upright post 1. During removal, the locking block 12 is slid upward so that the locking post 122 exits the locking groove 224, and the insert plates 223 are removed from the slots 111, separating the barrier 2 from the upright post 1. This design makes installation and removal of the guardrail very convenient and improves work efficiency. Furthermore, the provision of the elastic holding member 13 ensures that the locking block 12 is always locked, enhancing the stability of the guardrail. The scissor-type folding fence design allows the guardrail to be folded up when not in use, reducing space and making it easier to carry. Example 2

[0072] This embodiment differs from the previous embodiment in that the retractable barrier 21 is a retractable roller-type enclosure (not shown). This retractable roller-type enclosure comprises two housings, two reels, two coil springs, and a roller blind. The housings are vertically fixed to the connecting plate 22 and are made of a lightweight, high-strength aluminum alloy with excellent corrosion and wear resistance. The housing is rectangular in shape, and its interior is strategically designed to accommodate the reels, coil springs, and roller blind. The reels rotate within the housing and are made of stainless steel, offering excellent strength and wear resistance. The coil springs are fixed between the reels and the housing and are made of spring steel, offering excellent elasticity and durability. The ends of the roller blind are fixed to the reels and extend beyond the housing. The roller blind is made of waterproof canvas, offering excellent water resistance and wear resistance, effectively blocking dust and rain. The roller blind can also be coated with a reflective coating to enhance its warning effect in low-light conditions.

[0073] The connecting plates 22 are connected to both ends of the telescopic barrier 21 and are made of sturdy steel plates. The shape and size of the connecting plates 22 are designed according to the size of the rolling curtain telescopic enclosure. The connecting plates 22 are formed with plug-in plates 223 on the side facing away from the connecting plates 22. The plug-in plates 223 are made of the same steel plate as the connecting plates 22. The plug-in plates 223 are rectangular in shape and their dimensions are precisely designed to allow for smooth insertion into the slots 111 of the support body 11. A locking groove 224 is formed at the upper end of the plug-in plates 223 for mating with the lock column 122 of the locking block 12.

[0074] The working principle of this embodiment is as follows: During installation, the insert plates 223 on the connecting plates 22 at both ends of the telescopic barrier 21 are inserted into the slots 111 of the support body 11. The locking block 12 is then slid downward, so that the locking pins 122 on the locking block 12 are inserted into the locking grooves 224 on the insert plates 223, thereby locking the insert plates 223 and securing the barrier 2 to the upright post 1. During use, the rolling curtain is pulled, and the winding shaft rotates under the action of the winding spring, unfolding the curtain and forming a barrier. When not in use, the curtain is released, and the winding spring drives the winding shaft to rotate in the opposite direction, retracting the curtain, reducing the space occupied and facilitating portability.

[0075] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
