Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a height-adjustable protective fence for building engineering construction. Background Art

[0002] During the construction process, in order to ensure construction safety, construction workers will set up safety protection devices at the construction site for isolation. This is to prevent pedestrians and vehicles passing by from mistakenly entering the construction area, thereby avoiding potential safety risks. At the same time, the installation of safety protection devices also helps to keep the city clean and beautiful, prevent construction materials or garbage from being scattered on clean roads, and maintain the cleanliness and order of the city.

[0003] As an important equipment to ensure the safety of the project, the performance optimization of the protective fence used in construction projects is of vital importance. However, the common problem of non-adjustable height of existing products forces users to consider the geographical environment when choosing, which undoubtedly increases the difficulty and time cost of selection. Therefore, it is urgent to develop a height-adjustable protective fence for construction projects to adapt to different terrains and project requirements, improve construction efficiency, and reduce project costs.

[0004] In the prior art, a Chinese patent with a publication number of CN215595204U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: comprising a guardrail, a connecting mechanism is provided on both sides of the guardrail, the guardrail comprises a bottom guardrail, the top of the bottom guardrail is movably connected to the top guardrail, the top of the bottom guardrail is fixedly connected to a fixed rod, and the top of the fixed rod penetrates the interior of the top guardrail and is fixedly connected to a sliding plate. The utility model sets a connecting mechanism to push the top guardrail to move upward, increase the distance between the bottom guardrail and the top guardrail, and increase the height of the guardrail through the bottom guardrail and the top guardrail, thereby achieving the effect of being able to adjust the height, solving the problem that the existing protective fence for construction engineering cannot adjust the height, but the existing engineering construction safety protection device, its guardrail is mostly connected by bolts. This connection method requires the use of special tools when disassembling and assembling, and the operation is relatively cumbersome. In addition, when the guardrail is used to enclose the construction site, its flexibility at the corner is insufficient, the optional turning angle is limited, and it is difficult to adapt to the needs of different site shapes. In summary, the existing device needs to be improved in terms of convenience and adaptability. Utility Model Content

[0005] The utility model aims to provide a height-adjustable protective fence for construction engineering to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A height-adjustable protective fence for construction engineering, comprising a guardrail seat and a supporting rod body; the guardrail seat is symmetrically arranged on both sides of the supporting rod body, a rotating shaft is fixedly provided on the guardrail seat, and a guardrail assembly is rotatably connected to the rotating shaft; a rotating groove is provided on the supporting rod body, a screw rod is rotatably connected in the rotating groove, a moving block is provided on the screw rod, and the moving block and the screw rod are threadedly connected; sliding grooves are provided on both sides of the supporting rod body, and the moving block and the sliding grooves are slidably connected; a motor is provided at the top of the screw rod, and the transmission shaft of the motor is fixedly connected to the screw rod; a limit block is provided on one side of the guardrail assembly, a limit seat is provided on one side of the supporting rod body, the limit rod is slidably connected to the limit seat, a cross limit block is provided at the bottom end of the limit rod, and a limit groove matching the limit block is provided on the limit block.

[0008] When we need to adjust the height when using the guardrail, we start the motor, the motor drives the screw to rotate, and the rotation of the screw drives the moving block on the screw to move vertically. When the moving block moves upward along the screw, the moving block drives the guardrail assembly to move, and the guardrail assembly opens to increase the protective height of the guardrail; when the guardrail is used to enclose some construction sites, the corners are irregular and the flexibility at the corners is insufficient. By rotating the guardrail assembly along the shaft, we can adjust the required angle. When the angle adjustment is completed, by lowering the limit rod, the limit block is stuck in the limit slot, so that the angle of the guardrail is fixed, which is convenient and quick.

[0009] A further improvement of the technical solution of the utility model is that: the guardrail assembly includes a top rod, a lifting rod and a bottom rod, and one side of the top rod and the bottom rod is provided with a rotating sleeve, which is slidably connected to the rotating shaft; the limit block is fixedly connected to the rotating sleeve; the top rod, the lifting rod and the bottom rod are provided with a plug plate and a slot, and the plug plate and the slot are slidably connected; the lifting rod is slidably connected to the rotating shaft; a lifting groove is provided on one side of the moving block, and the lifting groove is slidably connected to the rotating sleeve, and both ends of the rotating sleeve are abutted against the lifting groove.

[0010] The above-mentioned technical scheme is adopted, in which a lifting groove is provided on one side of the moving block, and the two ends of the rotating sleeve are abutted against the lifting groove. When the screw rod drives the moving block to rise, the lifting groove rises with the moving block, and the rotating sleeve is slidably connected to the rotating shaft. The lifting groove will drive the rotating sleeve to rise and then drive the top rod to rise. The plug plate of the top rod slides and drives the plug plates on the lifting rod and the bottom rod to slide upward, thereby increasing the protection height of the guardrail assembly.

[0011] A further improvement of the technical solution of the utility model is that one end of the top rod, the lifting rod and the bottom rod on one side of the supporting rod body is provided with an assembly groove, and one end of the top rod, the lifting rod and the bottom rod on the other side is provided with an assembly head.

[0012] By adopting the above technical solution, an assembly head is provided in the solution. When we need to lengthen the guardrail, we can simply assemble the spare assembly guardrail with the guardrail to be lengthened, which is simple and convenient.

[0013] The further improvement of the technical solution of the utility model is that: a fixing rod is slidably provided on one side of the top rod, the lifting rod and the bottom rod, and a fixing groove matching with the fixing rod is provided on the plug plate; the fixing rod is slidably connected with the plug plate.

[0014] By adopting the above technical solution, the protective device in this solution is easily damaged when it is outdoors for a long time; when the lifting rod is damaged and needs to be repaired and replaced, by setting a fixing rod and a fixing groove, the fixing rod is pulled out, so that the fixing rod is separated from the fixing groove, thereby separating the plug plate and the lifting plate, so that the lifting rod can be inspected and repaired conveniently and quickly.

[0015] A further improvement of the technical solution of the utility model is that the side of the lifting rod in contact with the rotating shaft is an arc surface, a magnet is fixedly arranged on the arc surface, and the rotating shaft is made of magnetic metal.

[0016] The above technical solution is adopted. In this solution, the lifting rod and the rotating shaft are not fixed, and the device is easily unstable due to collision and wind. By setting a magnet, the lifting rod is adsorbed on the rotating shaft through the magnet, making the guardrail assembly more stable and improving the stability of the device.

[0017] A further improvement of the technical solution of the utility model is that a storage groove is fixedly provided at the bottom end of the support rod body, and a weight block is arranged in the storage groove.

[0018] The above technical solution is adopted, in which the center of the entire guard device is raised when the guardrail is lifted. Moreover, the guardrail is raised with the guardrail seat as the fulcrum, because the higher the guardrail assembly is, the longer the power arm is, so tall trees are easily knocked down. The center of gravity of the device is lowered by setting a weight block, thereby improving the stability of the device.

[0019] A further improvement of the technical solution of the utility model is that a pull groove and a positioning block are provided on one side of the support rod body, a pull rod is rotatably provided on the pull groove, a clamping head is provided at the end of the pull rod, and the weight block is slidably connected to the storage groove.

[0020] The above technical solution is adopted. In this solution, a clamping head is set. When fixing the base, a groove for the weight block is opened at the ground fixing position. Then the pull rod is rotated so that the pull rod leaves the clamping head and the weight block falls into the pressure groove, which is more stable.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides a height-adjustable protective fence for construction projects. When we need to adjust the height when using the guardrail, we start the motor, and the motor drives the screw to rotate. The rotation of the screw drives the moving block on the screw to move in the vertical direction. When the moving block moves upward along the screw, the moving block drives the guardrail assembly to move, and the guardrail assembly opens to increase the protective height of the guardrail; when the guardrail is used to enclose some construction sites, the edges and corners are irregular and the flexibility at the corners is insufficient. By rotating the guardrail assembly along the rotating shaft, we can adjust the required angle. When the angle adjustment is completed, by lowering the limit rod, the limit block is stuck in the limit groove, so that the angle of the guardrail is fixed, which is convenient and quick.

[0023] 2. The utility model provides a height-adjustable protective fence for construction projects. By setting a lifting groove, the two ends of the rotating sleeve are abutted against the lifting groove. When the screw rod drives the moving block to rise, the lifting groove rises with the moving block, and the rotating sleeve is slidably connected to the rotating shaft. The lifting groove will drive the rotating sleeve to rise and then drive the top rod to rise. The plug plate of the top rod slides and drives the plug plates on the lifting rod and the bottom rod to slide upward, thereby increasing the protective height of the guardrail assembly.

[0024] 3. The utility model provides a height-adjustable protective fence for construction engineering. By setting a fixing rod and a fixing groove, the fixing rod is pulled out to separate the fixing rod from the fixing groove, thereby separating the plug plate from the lifting plate, so that the lifting rod can be inspected and maintained quickly and conveniently.

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the embodiments:

[0033] Example 1

[0034] like Figure 1-5 As shown, the utility model provides a height-adjustable protective fence for construction engineering, including a guardrail seat 1 and a support rod body 2; the guardrail seat 1 is symmetrically arranged on both sides of the support rod body 2, and a rotating shaft 3 is fixedly provided on the guardrail seat 1, and a guardrail assembly 4 is rotatably connected to the rotating shaft 3; a rotating groove is provided on the support rod body 2, and a screw rod 5 is rotatably connected in the rotating groove, and a moving block 6 is provided on the screw rod 5, and the moving block 6 and the screw rod 5 are threadedly connected; slide grooves 7 are provided on both sides of the support rod body 2, and the moving block 6 and the slide groove 7 are slidably connected; a motor 8 is provided at the top of the screw rod 5, and the transmission shaft of the motor 8 is fixedly connected to the screw rod 5; a limit block 9 is provided on one side of the guardrail assembly 4, and a limit seat 10 is provided on one side of the support rod body 2, and a limit rod 11 is slidably connected to the limit seat 10, and a cross limit block 9 is provided at the bottom end of the limit rod 11, and a limit groove matching therewith is provided on the limit block 9.

[0035] In this embodiment, when we need to adjust the height when using the guardrail, by starting the motor 8, the motor 8 drives the screw rod 5 to rotate, and the rotation of the screw rod 5 drives the moving block 6 on the screw rod 5 to move in the vertical direction. When the moving block 6 moves upward along the screw rod 5, the moving block 6 drives the guardrail assembly 4 to move, and the guardrail assembly 4 opens to increase the protective height of the guardrail; when the guardrail is used to enclose some construction sites, the corners are irregular and the flexibility at the corners is insufficient. By rotating the guardrail assembly 4 along the rotating shaft 3, we can adjust the required angle. After the angle adjustment is completed, by lowering the limit rod 11, the limit block 9 is stuck in the limit groove, so that the angle of the guardrail is fixed, which is convenient and quick.

[0036] In this embodiment, preferably, the guardrail assembly 4 includes a top rod 12, a lifting rod 13 and a bottom rod 14, and a rotating sleeve 15 is provided on one side of the top rod 12 and the bottom rod 14, and the rotating sleeve 15 is slidably connected to the rotating shaft 3; the limit block 9 is fixedly connected to the rotating sleeve 15; the top rod 12, the lifting rod 13 and the bottom rod 14 are provided with an insert plate 16 and a slot 17, and the insert plate 16 and the slot 17 are slidably connected; the lifting rod 13 is slidably connected to the rotating shaft 3; a lifting groove 20 is provided on one side of the moving block 6, and the lifting groove 20 is slidably connected to the rotating sleeve 15, and the two ends of the rotating sleeve 15 are abutted against the lifting groove 20.

[0037] A lifting groove 20 is provided on one side of the moving block 6, and the two ends of the rotating sleeve 15 are abutted against the lifting groove 20. When the screw rod 5 drives the moving block 6 to rise, the lifting groove 20 rises with the moving block 6, and the rotating sleeve 15 is slidably connected to the rotating shaft 3. The lifting groove 20 will drive the rotating sleeve 15 to rise and then drive the top rod 12 to rise. The plug plate 16 of the top rod 12 slides and drives the lifting rod 13 and the plug plate 16 on the bottom rod 14 to slide upward, thereby increasing the protection height of the guardrail assembly 4.

[0038] The guardrail assembly 4 is mostly made of lightweight wood to prevent the moving block 6 from being unable to drive the lifting due to excessive weight.

[0039] Preferably, one end of the top rod 12, the lifting rod 13 and the bottom rod 14 on one side of the support rod body 2 is provided with an assembly groove 28, and one end of the top rod 12, the lifting rod 13 and the bottom rod 14 on the other side is provided with an assembly head 29.

[0040] By providing the assembling head 29, when we need to lengthen the guardrail, we can simply assemble the spare assembling guardrail with the guardrail to be lengthened, which is simple and convenient.

[0041] Example 2

[0042] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, a fixing rod 21 is slidably provided on one side of the top rod 12, the lifting rod 13 and the bottom rod 14, and a fixing groove 22 matching the fixing rod 21 is provided on the plug plate 16; the fixing rod 21 is slidably connected to the plug plate 16.

[0043] In this embodiment, the protective device is easily damaged when it is outdoors for a long time; when the lifting rod 13 is damaged and needs to be repaired and replaced, the fixing rod 21 and the fixing groove 22 are set, and the fixing rod 21 is pulled out, so that the fixing rod 21 is separated from the fixing groove 22, thereby separating the plug plate 16 from the lifting plate, so that the lifting rod 13 can be inspected and repaired quickly and conveniently.

[0044] Example 3

[0045] On the basis of Example 1, the utility model provides a technical solution: preferably, the side of the lifting rod 13 in contact with the rotating shaft 3 is an arc surface, a magnet is fixed on the arc surface, and the rotating shaft 3 is made of magnetic metal.

[0046] In this embodiment, the lifting rod 13 is not fixed to the rotating shaft 3, and the device may be easily unstable due to collision or wind. By setting a magnet, the lifting rod 13 is adsorbed on the rotating shaft 3 through the magnet, making the guardrail assembly 4 more stable and improving the stability of the device.

[0047] Example 4

[0048] On the basis of Example 1, the utility model provides a technical solution: preferably, a storage groove is fixedly provided at the bottom end of the support rod body 2, and a weight block 23 is provided in the storage groove.

[0049] In this embodiment, the guardrail will raise the center of the entire guard device when it is lifted. Moreover, the guardrail is raised with the guardrail seat 1 as the fulcrum, because the higher the guardrail assembly 4 is, the longer the power arm is, so tall trees are easily knocked down. The center of gravity of the device is lowered by setting the weight block 23, thereby improving the stability of the device.

[0050] Preferably, a pull groove 24 and a positioning block 25 are provided on one side of the support rod body 2, a pull rod is rotatably provided on the pull groove 24, a clamping head 27 is provided at the end of the pull rod, and the weight block 23 is slidably connected to the storage groove.

[0051] By setting the clamping head 27, when fixing the base, a groove for the weight block 23 is opened at the ground fixing position, and then the pull rod is rotated so that the pull rod leaves the clamping head 27, and the weight block 23 falls into the pressing groove, which is more stable.

[0052] The following is a detailed description of the working principle of the protective device used in the construction of intelligent building projects.

[0053] like Figure 1-5 As shown, when we need to adjust the height when using the guardrail, by starting the motor 8, the motor 8 drives the screw rod 5 to rotate, and the rotation of the screw rod 5 drives the moving block 6 on the screw rod 5 to move in the vertical direction. When the screw rod 5 drives the moving block 6 to rise, the lifting groove 20 rises with the moving block 6, and the rotating sleeve 15 is slidably connected to the rotating shaft 3. The lifting groove 20 will drive the rotating sleeve 15 to rise and then drive the top rod 12 to rise. The plug plate 16 of the top rod 12 slides and drives the plug plate 16 on the lifting rod 13 and the bottom rod 14 to slide upward, thereby increasing the protective height of the guardrail assembly 4. When the guardrail is used to enclose some construction sites, the corners are irregular and the flexibility at the corners is insufficient. By rotating the guardrail assembly 4 along the rotating shaft 3, we can adjust the angle we need. After the angle adjustment is completed, by lowering the limit rod 11, the limit block 9 is stuck in the limit groove, so that the angle of the guardrail is fixed, which is convenient and quick.

[0054] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
