Description

Technical Field

[0001] The utility model relates to the technical field of building engineering safety protection, in particular to a building engineering safety fence. Background Art

[0002] Construction project safety fences are a type of protective facility set up around construction sites or in specific areas to ensure the safety of people and vehicles inside and outside the site and prevent accidents. Safety fences usually use fences, fences or other enclosures to restrict access to the area, and are equipped with warning signs and warning lights to remind people to pay attention to safety.

[0003] For example, a Chinese utility model patent (CN 218206120 U) discloses a construction engineering safety fence, which records: "By setting a sliding seat, a semicircular block, a docking block, a ring, a reset mechanism and a locking mechanism, people can adjust the distance between each nozzle according to the construction situation, and can also fix the water pipe conveniently through a simple structure, reducing the time wasted by using tools when using wire binding, improving people's work efficiency, and reducing the waste of wire." It also records: "Nowadays, nozzles are generally installed on safety fences. During installation, the water pipes are generally tied to the fence with wires. The bundling is inconvenient and affects people's work efficiency. The tied wires are generally discarded directly after use, which will cause waste of wire." Technical problems.

[0004] To sum up the above, it can be known that in the prior art, movable bayonet is used to fix the water pipe on the fence to avoid the material waste of traditional wire fixing. However, this method has the following technical problems: the traditional method of fixing the water pipe on the safety fence cannot adjust the height of the water pipe nozzle, and cannot make corresponding adjustments according to the conditions of the construction site, which affects the effect of water spraying and dust reduction. At the same time, when a support rod of the fence is damaged, the entire fence needs to be replaced, resulting in an increase in maintenance costs. For this reason, the present application proposes a construction project safety fence to provide a new technical solution to solve the technical problems mentioned in the above patents.

[0032] As shown in the background technology, the traditional method of fixing the water pipe on the safety fence cannot adjust the height of the water pipe nozzle, and cannot make corresponding adjustments according to the conditions of the construction site, which affects the effect of spraying water to reduce dust. At the same time, when a support rod of the fence is damaged, the entire fence needs to be replaced, resulting in an increase in maintenance costs.

[0033] In order to solve this technical problem, the utility model provides a construction engineering safety fence, which is used for adjusting the height of a sprinkler head and for replacing a separate railing.

[0034] Specifically, please refer to Figure 1-Figure 4 , construction engineering safety fences specifically include:

[0035] It includes a support frame 1, a U-shaped limiting frame 2 is fixedly connected to the outside of the support frame 1, a support plate 3 is fixedly connected to the inside of the support frame 1, a railing mechanism 4 is arranged inside the support plate 3, the railing mechanism 4 is arranged inside the U-shaped limiting frame 2, and a replacement mechanism 5 is arranged outside the railing mechanism 4;

[0036] The handrail mechanism 4 comprises a mounting shell 10 , a sliding shell 11 is slidably connected to the interior of the mounting shell 10 , and a plurality of limiting grooves 12 are formed inside the mounting shell 10 .

[0037] The construction engineering safety fence provided by the utility model releases the restriction between the rotating cover 13 and the sliding shell 11 by pulling up the insertion rod 17, and then the rotating cover 13 can be rotated to release the restriction between the block 21 and the restriction groove 12, and then the sliding shell 11 can be pulled or pressed to adjust the overall height between the sliding shell 11 and the mounting shell 10, and then the water spraying height of the water spraying pipe installed on the fixed bottom shell 14 and the movable shell 15 can be adjusted, and the height of the water spraying head can be adjusted according to the situation of the construction site, thereby changing the water spraying area and improving the dust reduction effect on the construction site. The device can be flexibly adjusted according to the usage scenario, thereby improving the practicality of the device.

[0038] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0039] Embodiment 1:

[0040] Please refer to Figure 4-Figure 7 , a construction engineering safety fence, comprising:

[0041] The top of the sliding shell 11 is rotatably connected to a rotating cover 13, the top of the rotating cover 13 is fixedly connected to a fixed bottom shell 14, the top of the fixed bottom shell 14 is movably connected to a movable shell 15, the middle of the fixed bottom shell 14 is threadedly connected to a mounting bolt 16, the fixed bottom shell 14 and the movable shell 15 are threadedly connected by the mounting bolt 16, and the fixed bottom shell 14 and the movable shell 15 are respectively provided with holes and grooves that adapt to the size of the water pipe nozzle to facilitate the installation of the water pipe nozzle.

[0042] The internal movement of the rotating cover 13 is connected to the plug rod 17. The plug rod 17 prevents the rotating cover 13 from rotating due to external force when the height between the sliding shell 11 and the mounting shell 10 is not adjusted, thereby causing the position between the sliding shell 11 and the mounting shell 10 to change. The restriction of the plug rod 17 is improved and the stability of the device is improved. The plug rod 17 is inserted into the interior of the sliding shell 11.

[0043] The bottom of the rotating cover 13 is located inside the sliding shell 11 and is fixedly connected to a rotating rod 18 , and the outside of the rotating rod 18 is fixedly connected to a driving gear 19 .

[0044] A first supporting groove 22 is provided on the outside of the sliding shell 11, and a second supporting groove 23 is provided on the outside of the sliding shell 11. A block 21 is movably connected inside the first supporting groove 22, and a movable rack 20 is movably connected inside the second supporting groove 23. The movable rack 20 is slidably connected inside the F-shaped block 24, and the F-shaped block 24 is fixedly connected to the bottom of the sliding shell 11. The first supporting groove 22 and the second supporting groove 23 provide support and restriction to the block 21 and the movable rack 20 to prevent the movable rack 20 from falling off, thereby improving the stability of the device.

[0045] One end of the movable rack 20 close to the first supporting groove 22 is fixedly connected to the outside of the block 21. The movable rack 20 is meshed with the outside of the driving gear 19. The block 21 is adapted to the limiting groove 12. The limiting constraint between the block 21 and the limiting groove 12 ensures that the overall height of the sliding shell 11 and the mounting shell 10 will not change, thereby improving the stability of the device.

[0046] Through the above structural design, the insertion rod 17 is removed, and then the rotating cover 13 is rotated, thereby driving the rotating rod 18 to rotate accordingly. The rotation of the rotating rod 18 drives the driving gear 19 to rotate, thereby driving the moving rack 20 to move toward the inside of the sliding shell 11, thereby releasing the restriction of the block 21 on the mounting shell 10 through the limiting groove 12, and then the sliding shell 11 can be pulled or pressed to change the overall height of the sliding shell 11 and the mounting shell 10. After the height between the sliding shell 11 and the mounting shell 10 is adjusted to a suitable position, the rotating cover 13 is rotated in the opposite direction, thereby driving the driving gear 19 to rotate through the rotating rod 18, so that the moving rack 20 can move to the inside of the sliding shell 11. The strip 20 drives the block 21 to move to the outside of the sliding shell 11, so that the block 21 moves to the inside of the corresponding limiting groove 12. After the position of the sliding shell 11 and the mounting shell 10 are adjusted, the mounting bolts 16 are rotated to disengage the mounting bolts 16 from the fixed bottom shell 14 and the movable shell 15, and then the movable shell 15 is removed, and the water pipe is placed in the corresponding groove on the fixed bottom shell 14, and then the movable shell 15 is placed in a suitable position on the fixed bottom shell 14, and then the mounting bolts 16 are rotated and inserted into the movable shell 15 and the fixed bottom shell 14, and the height adjustment of the installation place of the water pipe nozzle and the installation of the water pipe nozzle are completed.

[0047] Embodiment 2:

[0048] The construction engineering safety fence provided in Example 1 is further optimized, specifically, as follows: Figure 3 As shown, the replacement mechanism 5 includes a first thread groove 6 opened inside the U-shaped limiting frame 2, and a thread strip 7 is fixedly connected to the outside of the mounting shell 10, and the first thread groove 6 is adapted to the thread strip 7.

[0049] A threaded column 8 is fixedly connected to the bottom of the mounting shell 10 , and a second threaded groove 9 is formed inside the supporting plate 3 , and the threaded column 8 is matched with the second threaded groove 9 .

[0050] Through the above structural design, when a railing mechanism 4 on the device is damaged, it is only necessary to rotate the mounting shell 10 so that the mutual restriction between the first thread groove 6 and the threaded strip 7 and the threaded column 8 and the second thread groove 9 is released, and then the end of the intact railing mechanism 4 with the threaded column 8 is first passed through the corresponding through hole on the U-shaped limiting frame 2. When the threaded column 8 is located above the corresponding hole groove on the support plate 3, the mounting shell 10 is rotated, so that the threaded column 8 is rotated into the appropriate position in the second thread groove 9, and the threaded strip 7 is rotated into the appropriate position in the first thread groove 6, thereby completing the installation of the railing mechanism 4.
