[0002] Municipal infrastructure refers to the various buildings, structures, and equipment installed within the planned construction areas of urban areas and towns, providing paid or unpaid public goods and services to residents based on government responsibilities and obligations. Examples include common urban roads, bridges, subways, underground pipelines, tunnels, rivers, rail transit, sewage treatment, and waste disposal projects. During the construction of municipal projects, numerous safety and protective structures are typically required.

[0003] In the related art, an installation groove is usually opened outside the road that needs to be constructed, and a protective wall is installed in the installation groove.

[0008] By adopting the above technical solution, when the baffle located in the installation groove needs to be moved out, the baffle is first raised to a position above the installation groove through the height adjustment mechanism in the installation shell, and then the pulley and slide rod in the installation slot are rotated to leave the installation slot, and then the baffle is rotated to be staggered with the installation groove through the rotation mechanism, and the pulley is in contact with the road surface, and then the baffle is pushed to shrink the connecting part, thereby extending and retracting the rotation mechanism to leave the baffle, and finally the pulley is moved to move the baffle. Compared with building a protective wall with multiple bricks in the installation groove and then removing the bricks one by one and transporting them out of the installation groove one by one, the work efficiency is improved through the safety protection structure.

[0009] Optionally, the height adjustment mechanism includes a lifting block, a lifting rod and a driving assembly. A fixing groove for the lifting rod to pass through is provided on one end of the baffle close to the height adjustment mechanism. The height of the lifting rod is less than the height of the fixing groove. A lifting groove is provided on the lifting rod. One end of the lifting groove passes through the side wall of the lifting rod. The lifting block is lifted and lowered in the lifting groove. The screw passes through the lifting block and is threadedly connected to the lifting block. A push rod is fixedly connected to the lifting block. The lifting block can be raised until the push rod abuts against the bottom wall of the baffle upward, and the driving assembly is used to drive the screw to rotate.

[0010] When the lifting plate is in the fixed groove, the lifting block is driven by the lifting assembly to move upward in the lifting groove, thereby driving the push rod to move upward until the push rod abuts against the bottom wall of the baffle, and continues to push the baffle upward until the baffle is higher than the mounting groove; when the baffle is placed in the mounting groove, the lifting rod is first aligned with the fixed groove, and the push rod is driven to abut against the bottom wall of the baffle, and then the pulley is rotated to leave the mounting groove by rotating the slide rod, and then the baffle is rotated to be parallel to the mounting groove by the rotating mechanism, and the baffle is located directly above the mounting groove, and then the driving assembly is started to move the lifting block downward in the lifting groove, driving the push rod to move downward until the lifting rod passes through the fixed groove, and at the same time the lifting rod limits the baffle, making it difficult for the baffle to move in the mounting groove, thereby improving the stability of the baffle installation.

[0011] Optionally, the driving assembly includes a rotating motor and a bevel gear, the first bevel wheel of the bevel gear is fixedly connected to the screw and coaxially arranged, and the second bevel wheel of the bevel gear is connected to the rotating shaft of the rotating motor and coaxially arranged.

[0012] By adopting the above technical solution, when the baffle needs to be moved out of the mounting groove, the rotating motor is started to drive the screw to rotate, thereby driving the lifting block to push the push rod upward to abut against the bottom wall of the baffle, and push the baffle upward to be higher than the mounting groove and move the lifting rod out of the fixed groove; when placing the baffle again, first align the lifting rod with the fixed groove, start the rotating motor, make the push rod abut against the bottom wall of the baffle, and move the pulley to leave the mounting slot by rotating the slide rod, and then rotate the baffle to be parallel to the mounting groove through the rotating mechanism, and the baffle is located directly above the mounting groove, and then start the rotating motor to move the push rod downward, so that the lifting rod passes through the fixed groove, thereby realizing the driving height adjustment mechanism.

[0013] Optionally, the cross section of the lifting slot is convex-shaped, and the lifting block is adapted to the lifting slot.

[0014] By adopting the above technical solution, the lifting block is not likely to fall out of the lifting slot, thereby improving the lifting stability of the lifting block.

[0016] By adopting the above technical solution, when the baffle is raised to the outside of the installation groove, one end of the rotating block is located in the rotating groove, and the rotating motor is started. The cross-section of the rotating block is not circular and is adapted to the cross-sectional shape of the rotating groove, which makes it easier for the rotating block to drive the baffle to rotate.

[0017] Optionally, the connecting member includes an inner rod and a limiting member, a telescopic slot is provided at the bottom end of the rotating block, one end of the inner rod is connected to the rotating shaft of the driving motor, and the other end of the inner rod is slidably connected to the telescopic slot, the limiting member is arranged in the telescopic slot, a spring is provided on the inner rod, and the limiting member is used to limit the inner rod in the telescopic slot.

[0018] By adopting the above technical solution, when the baffle is raised and rotated away from the installation groove, the inner rod is extended and retracted in the telescopic groove to move the rotating block out of the rotating groove, thereby facilitating the movement of the baffle.

[0019] Optionally, a slider is provided on one end of the inner rod located in the telescopic slot, and the inner rod is slidably mounted on the inner wall of the telescopic slot via the slider.

[0020] By adopting the above technical solution, when the inner rod is extended and retracted in the telescopic slot, the contact area between the inner rod and the inner wall of the telescopic slot is increased, thereby limiting the position of the inner rod and improving the stability of the inner rod installation.

[0021] Optionally, the limiting member is a limiting ring, which is located at the bottom end of the rotating block and abuts against the peripheral side wall of the inner rod.

[0022] By adopting the above technical solution, when the inner rod is extended or retracted, the rotating block further limits the inner rod through the limiting ring, so that when the inner rod is extended or retracted in the telescopic slot, it is not easy to pop out of the telescopic slot due to excessive spring elasticity, thereby improving the stability of the inner rod installation.

[0023] Optionally, one end of the rotating block located in the rotating groove is connected to a connecting block, and the end of the connecting block away from the rotating block is wedge-shaped; when the rotating block can drive the baffle to rotate, the connecting block is still located in the rotating groove.

[0024] By adopting the above technical solution, when the baffle is raised above the mounting groove, the end of the connecting block close to the mounting shell abuts against the rotating groove, so that when the baffle moves toward the road surface, pressure is applied to the lower end of the connecting block, so that the connecting block drives the rotating block to press the inner rod downward to extend and retract, thereby facilitating the rotating block to move out of the rotating groove.

[0025] Optionally, a fixing assembly is provided on the sliding rod, and the fixing assembly includes a fixing rod and a fixing bolt. The sliding rod is connected to the baffle through the fixing rod, and fixing holes for the fixing bolts to pass through are provided on the sliding rod and the inner wall of the mounting slot. When the sliding rod and the pulley rotate into the mounting slot, the fixing bolts pass through the fixing holes and are threadedly connected to the inner wall of the mounting slot.

[0026] By adopting the above technical solution, when the baffle is raised and rotated to leave the mounting groove, the pulley is rotated from the mounting groove to abut against the ground through the slide rod, and the fixing bolt passes through the slide rod and the fixing holes on the inner wall of the mounting groove and is threadedly connected to the inner wall of the mounting groove, so that the pulley is not easy to fall off the baffle during movement; when the baffle is put back into the mounting groove, the pulley and the slide rod are rotated into the mounting groove again, and the fixing bolt passes through the fixing hole and is threadedly connected to the inner wall of the mounting groove, thereby fixing the slide rod and the pulley to the baffle, with a simple structure and easy installation.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Through the arrangement of the height adjustment mechanism and the rotation mechanism, when the baffle located in the installation groove needs to be moved out, the height adjustment mechanism in the installation shell is used to first raise the baffle to a position above the installation groove, and then the pulley and slide rod in the installation slot are rotated to leave the installation slot. The baffle is then rotated by the rotation mechanism to be staggered with the installation groove, and the pulley is in contact with the road surface. Then, the baffle is pushed to retract the connecting piece, thereby extending and retracting the rotation mechanism to leave the baffle, and finally the pulley is moved to move the baffle. Compared with building a protective wall with multiple bricks in the installation groove and then removing the bricks one by one and then moving them out of the installation groove one by one, the safety protection structure improves work efficiency;

[0029] When the lifting plate is in the fixed groove, the lifting block is driven by the driving assembly to move upward in the lifting groove, thereby driving the push rod to move upward until the push rod abuts against the bottom wall of the baffle, and continues to push the baffle upward until the baffle is higher than the mounting groove; when the baffle is placed in the mounting groove, the lifting rod is first aligned with the fixed groove, and the push rod is driven to abut against the bottom wall of the baffle, and then the pulley is rotated to leave the mounting groove by rotating the slide rod, and then the baffle is rotated to be parallel to the mounting groove by the rotating mechanism, and the baffle is located directly above the mounting groove, and then the driving assembly is started to make the lifting block move downward in the lifting groove, driving the push rod to move downward until the lifting rod passes through the fixed groove, and at the same time the lifting rod limits the baffle, so that the baffle is not easy to move in the mounting groove, thereby improving the stability of the baffle installation;

[0030] 3. Through the setting of the connecting block, when the baffle is raised to above the mounting groove, the connecting block is still located in the rotating groove, and the end of the connecting block close to the mounting shell abuts against the rotating groove. When the baffle moves toward the road surface, pressure is applied to the lower end of the connecting block, so that the connecting block drives the rotating block to press downward to extend and retract the inner rod. After the baffle is removed, the connecting block returns to its original position under the action of the spring, thereby facilitating the rotating block to move out of the rotating groove.

[0039] The following is combined with Figure 1-7 This application is described in further detail.

[0040] The embodiment of the present application discloses a combined safety protection structure for urban municipal engineering construction. Figure 1The combined safety protection structure for urban municipal engineering construction includes a baffle 1 and a mounting shell 2. A mounting groove 31 for installing the baffle 1 and the mounting shell 2 is opened on the ground 3. The mounting shell 2 is located on the bottom wall of the mounting groove 31. The baffle 1 is closer to the ground 3 than the mounting shell 2, and the height of the top of the baffle 1 is higher than the height of the opening of the mounting groove 31. Two sets of height adjustment mechanisms 21 and a rotating mechanism 22 are installed in the mounting shell 2. The rotating mechanism 22 is located in the middle of the mounting shell 2, and the height adjustment mechanism 21 is located at both ends of the rotating mechanism 22. The rotating mechanism 22 is rotatably connected to the baffle 1. The rotating mechanism 22 is used to rotate the baffle 1 to be staggered with the mounting groove 31, and the height adjustment mechanism 21 is used to drive the baffle 1 to rise and fall. Two pulleys 11 are rotatably mounted on the bottom end of the baffle 1. Slide rods 12 are fixedly connected to the pulleys 11. A mounting slot 13 is defined at the bottom end of the baffle 1 for mounting the pulleys 11 and slide rods 12. The pulleys 11 are rotatably connected to the inner walls of the mounting slots 13 via the slide rods 12. When the bottom end of the baffle 1 is above the ground 3, the pulleys 11 and slide rods 12 can be rotated until they abut against the ground 3. The pulleys 11 and slide rods 12 can also be rotated until both are secured within the mounting slots 13. The safety mechanism also includes a connector 4, through which the rotating mechanism 22 is telescopically mounted within the mounting housing 2.

[0041] When the baffle 1 needs to be moved out of the mounting groove 31, the baffle 1 is first raised to above the ground 3 through the height adjustment mechanism 21, and then the pulley 11 is rotated from the mounting groove 13 to leave the mounting groove 13, and the baffle 1 is rotated to be staggered with the mounting groove 31 through the rotating mechanism 22, and the pulley 11 abuts against the road surface, and then the rotating mechanism 22 is rebounded to away from the baffle 1 through the connecting member 4, and finally the baffle 1 is moved by the pulley 11, thereby improving the working efficiency.

[0042] Reference Figure 1 、 Figure 2 and Figure 7 , also includes a fixing component 5, the slide rod 12 and the pulley 11 are fixed to the inner wall of the mounting slot 13 through the fixing component 5, and the fixing component 5 includes a fixing rod 51 and a fixing bolt 52. One end of the fixing rod 51 is fixedly connected to the peripheral side wall of the sliding rod 12, and the other end of the fixing rod 51 is rotatably connected to the inner wall of the mounting slot 13. The sliding rod 12 and the top wall and side wall inside the mounting slot 13 are all provided with fixing holes 121. The fixing hole 121 located on the top wall inside the mounting slot 13 is a first fixing hole 1211, and the fixing hole 121 located on the side wall inside the mounting slot 13 is a second fixing hole 1212. When the pulley 11 and the sliding rod 12 rotate into the mounting slot 13, the fixing bolt 52 passes through the first fixing hole 1211 and is threadedly connected to the top wall inside the mounting slot 13; when the pulley 11 and the sliding rod 12 rotate to abut against the road surface, the fixing bolt 52 passes through the second fixing hole 1212 and is threadedly connected to the side wall inside the mounting slot 13.

[0043] When installing the baffle 1, first loosen the fixing bolt 52, remove the fixing bolt 52, and rotate the pulley 11 to leave the mounting slot 13. At the same time, the fixing bolt 52 passes through the second fixing hole 1212 and is threadedly connected to the inner side wall of the mounting slot 13. Move the baffle 1 to the specified position through the pulley 11, and support the baffle 1 with the height adjustment mechanism 21. Then rotate the pulley 11 into the mounting slot 13, pass the fixing bolt 52 through the first fixing hole 1211 and is threadedly connected to the inner top wall of the mounting slot 13, and tighten the fixing bolt 52 to fix the pulley 11. The structure is simple and the installation is convenient.

[0044] Reference Figure 1 and Figure 3 Each set of height adjustment mechanisms 21 includes a lifting block 211, a lifting rod 212 and a driving assembly 213. A fixing groove 14 for the lifting rod 212 is provided on the end of the baffle 1 close to the height adjustment mechanism 21, and a lifting groove 2121 is provided on the lifting rod 212. One side of the lifting groove 2121 passes through the side wall of the lifting rod 212. The cross-section of the lifting groove 2121 is a convex shape. The lifting block 211 is adapted to the lifting groove 2121. The end of the lifting block 211 close to the opening of the lifting groove 2121 is located outside the lifting groove 2121, so that the lifting block 211 is not easy to fall out of the lifting groove 2121, thereby improving the stability of the installation of the lifting block 211. The lifting block 211 is installed in the lifting slot 2121 for lifting. The screw 2111 passes through the lifting block 211 and is threadedly connected to the lifting block 211. A push rod 2112 is fixedly connected to the lifting block 211. The lifting block 211 can be lifted and lowered until the push rod 2112 is upward and abuts against the top wall of the fixed slot 14. The driving assembly 213 is used to drive the screw 2111 to rotate.

[0045] When installing the baffle 1, start the driving component 213 to move the lifting block 211 up and down until the push rod 2112 abuts against the bottom wall of the baffle 1, then rotate the pulley 11 to be located in the installation slot 13, and rotate the baffle 1 to be directly above the installation groove 31 through the rotating mechanism 22, and then start the driving component 213, and move the baffle 1 downward through the push rod 2112 until the lifting rod 212 is located in the fixing groove 14. The lifting rod 212 limits the baffle 1, making it difficult for the baffle 1 to move, thereby improving the stability of the installation of the baffle 1.

[0046] Reference Figure 3 and Figure 4The drive assembly 213 includes a rotary motor 2131 and a bevel gear. The first bevel gear 2132 of the bevel gear is fixedly connected to and coaxially arranged with the screw 2111. The second bevel gear 2133 of the bevel gear is connected to and coaxially arranged with the rotating shaft of the rotary motor 2131. When the push rod 2112 is driven, the rotary motor 2131 is activated, causing the screw 2111 to begin rotating, driving the lifting block 211 to move up and down, thereby achieving the up and down movement of the push rod 2112.

[0047] Reference Figure 1 and Figure 5 The rotating mechanism 22 includes a drive motor 221 and a rotating block 222. The rotating block 222 is coaxially mounted on the rotating shaft of the drive motor 221. The baffle 1 is provided with a rotating groove 15 for the rotating block 222 to penetrate. The cross-section of the rotating block 222 is non-circular and matches the cross-sectional shape of the rotating groove 15. A connecting block 2221 is integrally formed on the end of the rotating block 222 located within the rotating groove 15. When the connecting block 2221 is at its highest position, it is above the ground 3 and can extend into the rotating groove 15. The lowest end of the connecting block 2221 is higher than the highest end of the lifting rod 212. The end of the connecting block 2221 away from the rotating block 222 is wedge-shaped. When the rotating block 222 drives the baffle 1 to rotate, the end of the connecting block 2221 near the mounting shell 2 abuts the rotating groove 15.

[0048] When installing the baffle 1, first slide the baffle 1 through the pulley 11 until the connecting block 2221 is located directly below the rotating groove 15. At this time, the connecting block 2221 is at the highest end and located in the rotating groove 15, so that the push rod 2112 abuts against the bottom wall of the baffle 1. Start the drive motor 221, so that the connecting block 2221 drives the baffle 1 to rotate to the top of the installation groove 31, retract the pulley 11 and the slide rod 12, and then move the baffle 1 downward through the push rod 2112; when moving the baffle 1 out of the installation groove 31, first move the baffle 1 until the lifting rod 212 leaves the fixed groove 14. At this time, the lowest end of the wedge-shaped surface of the connecting block 2221 abuts against the lowest end of the inner wall of the rotating groove 15, rotate the pulley 11 until the pulley 11 leaves the installation slot 13, and then rotate the baffle 1 to the position aligned with the installation groove 31 through the connecting block 2221. 1 is staggered, and at this time the pulley 11 is in contact with the road surface. The baffle 1 is moved by the pulley 11, and the lowest end of the inner wall of the rotating groove 15 moves from the lowest end to the highest end of the wedge surface. The connecting block 2221 is subjected to downward pressure, and the retractable connecting member 4 is subjected to downward pressure, so that the connecting block 2221 and the rotating block 222 are moved downward through the connecting member 4 to leave the rotating groove 15, so that after the connecting block 2221 drives the baffle 1 to rotate, the baffle 1 can move the connecting block 2221 out of the rotating groove 15 by moving the pulley 11, thereby facilitating the movement of the baffle 1.

[0049] Reference Figure 1 、 Figure 5 and Figure 6The connecting member 4 includes an inner rod 41 and a stopper. A telescopic slot 2222 is defined at the bottom end of the rotating block 222. The height of the telescopic slot 2222 is smaller than that of the rotating block 222. One end of the inner rod 41 is connected to the rotating shaft of the drive motor 221, and the other end of the inner rod 41 is slidably connected within the telescopic slot 2222. The stopper is used to retain the inner rod 41 within the telescopic slot 2222. A spring 411 is sleeved on one end of the inner rod 41 located within the telescopic slot 2222. Two sliders 412 are fixedly connected to the sidewall of the inner rod 41 near the connecting block 2221. The height of the sliders 412 is higher than the height of the top of the spring 411. The stopper is a stop ring 42 located at the bottom end of the rotating block 222 and abutting against the sidewall of the inner rod 41.

[0050] When the baffle 1 moves, the bottom surface of the baffle 1 applies pressure to the wedge-shaped surface, causing the rotating block 222 to move downward. The spring 411 on the inner rod 41 is subjected to downward pressure, causing the slider 412 on the inner rod 41 to slide downward. When the connecting block 2221 leaves the rotating groove 15, the spring 411 rebounds, causing the inner rod 41 to move upward, thereby restoring the rotating block 222 and the connecting block 2221. The stop ring 42 and the slider 412 cooperate with each other, preventing the inner rod 41 from being ejected from the telescopic groove 2222 due to excessive elastic force during extension and contraction, thereby improving the stability of the installation of the inner rod 41.

[0051] The implementation principle of the combined safety protection structure for urban municipal engineering construction in the embodiment of the present application is as follows: before installing the baffle 1, the mounting shell 2 is first placed on the bottom wall of the mounting groove 31, and the baffle 1 is moved to the top of the mounting groove 31 by the pulley 11, with the length direction of the baffle 1 being staggered with the length direction of the mounting groove 31, and the connecting block 2221 is positioned in the rotation groove 15 behind the moved baffle 1. During the process of the baffle 1 moving until the connecting block 2221 is positioned in the rotation groove 15, the baffle 1 cooperates with the wedge-shaped surface on the connecting block 2221, and the connecting block 2221 is first pressed downward until the connecting block 2221 moves to align with the rotation groove 15. The connecting block 2221 automatically extends under the action of the spring 411 and extends into the rotation groove 15.

[0052] Then, the driving assembly 213 is started to move the push rod 2112 upward until it contacts the bottom wall of the baffle 1, and the slide bar 12 is rotated so that the slide bar 12 and the pulley 11 are stored in the installation slot 13. Then, the baffle 1 is rotated to be parallel to the installation groove 31 by rotating the connecting block 2221. At this time, the baffle 1 is located directly above the installation groove 31. The push rod 2112 is then driven downward to move the bottom end of the baffle 1 into the installation shell 2 and the lifting rod 212 is located in the fixing slot 14, forming a limit for the baffle 1, making it difficult for the baffle 1 to move in the installation shell 2, thereby improving the stability of the installation of the baffle 1.

[0053] When the baffle 1 needs to be moved out of the mounting groove 31, the rotating motor 2131 is first started to move the lifting block 211 upward, driving the push rod 2112 upward until the baffle 1 is pushed above the ground 3 and the lifting rod 212 is moved out of the fixing groove 14. The fixing bolts 52 in the mounting groove 13 are loosened, and the slide bar 12 is removed from the inner wall of the mounting groove 13. Then, the baffle 1 is rotated by the rotating mechanism 22 until it is staggered with the mounting groove 31. During the process of rotating the baffle 1 to the staggered arrangement with the mounting groove 31, the width of the push rod 2112 can be adjusted according to actual conditions so that the bottom end of the baffle 1 is first supported by the push rod 2112 until the baffle 1 rotates to abut against the pulley 11 against the ground 3. The baffle 1 is then pushed and, under the action of the wedge-shaped surface of the baffle 1 and the connecting block 2221, the baffle 1 is finally moved away by the moving pulley 11.

[0054] 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.
