Description

Technical Field

[0001] This application relates to the technical field of construction protection, and in particular to a construction protection device for the top of a movable elevated crash barrier. Background Technology

[0002] Currently, when constructing new elevated roads or reinforcing and upgrading existing ones in many cities, it is often necessary to carry out high-altitude operations on top of the crash barriers. The area below the work site is a key safety protection zone, such as municipal traffic roads and rail transit. Therefore, before carrying out construction work on top of the elevated crash barriers, it is necessary to consider measures to prevent falling objects and thrown objects during the operation to ensure the safety of the space below during high-altitude construction and to increase the safety of the workers.

[0003] Traditional elevated crash barrier construction typically uses a steel frame and protective panels to form the protective structure. Before construction work on the top of the crash barrier is carried out, the frame is erected at the construction location on the crash barrier, and the steel frame is secured to the crash barrier with wooden wedges. Then, multiple protective panels are used to enclose the space on the frame for construction work, and construction work on the top of the crash barrier can then be carried out.

[0004] However, there are usually gaps between the protective panels and the crash barriers. When construction work is carried out on the crash barriers, especially when hot work is carried out on the top of the elevated crash barriers, the strong light generated by the hot work can easily seep through the gaps and interfere with the vision of vehicles on the road below, thereby affecting the driving safety of vehicles on the road below. Summary of the Invention

[0005] To improve safety during construction work on top of a crash barrier, this application provides a movable construction protection device for the top of an elevated crash barrier.

[0006] This application provides a movable construction protection device for the top of an elevated crash barrier, which adopts the following technical solution:

[0007] A movable elevated crash barrier top construction protection device includes a frame for erecting on the crash barrier, a clamping assembly for fixing the frame to the crash barrier, a protective plate fixedly installed on the frame, side plates fixedly installed on both sides of the frame and the protective plate, and a top plate installed on the top of the frame. The protective plate, the side plates and the top plate form a construction area for construction work.

[0008] A baffle is slidably mounted on the frame, with the ends of the baffle abutting against the side plates respectively. The baffle is used to close the gap between the protective plate and the crash barrier. A driving component is provided on the frame to drive the baffle to slide.

[0009] By adopting the above technical solution, the frame is erected at the construction location of the crash barrier, and the frame is fixed to the crash barrier by clamping components. The construction area is formed by the protective plate, side plates and top plate. Then, the baffle is driven by the driving component to slide, sealing and blocking the gap between the protective plate and the crash barrier. This effectively avoids the strong light generated by the construction work on the top of the crash barrier from interfering with the vision of vehicles on the road below, thereby greatly improving the safety of the construction work on the top of the crash barrier.

[0010] Optionally, the frame includes a support frame and a lifting frame. The clamping assembly is used to fix the support frame to the crash barrier. The lifting frame is lifted and lowered on the top of the support frame. The support frame is provided with a drive assembly for driving the lifting frame to lift and lower. The protective plate, side plates, and baffles are all fixedly installed on the support frame. The top plate is installed on the lifting frame. The support frame is provided with a three-proof cloth, which is fixedly connected to the lifting frame.

[0011] By adopting the above technical solution, the lifting frame is driven to rise by the drive component, providing a larger construction work space and improving practicality. After the lifting frame rises, the gap between the support frame and the lifting frame is covered and sealed by the three-proof cloth to ensure the protective effect.

[0012] Optionally, the drive assembly includes a threaded sleeve and a transmission screw. The threaded sleeve is rotatably mounted on the support frame, and the transmission screw is fixedly mounted on the lifting frame. The axial direction of the transmission screw is parallel to the sliding direction of the lifting frame, and the transmission screw passes through the threaded sleeve and is threadedly engaged with the threaded sleeve.

[0013] By adopting the above technical solution, the transmission screw is driven to slide along the axial direction of the screw sleeve by rotating the screw sleeve, thereby driving the lifting frame to slide. When the screw sleeve stops rotating, the lifting frame can be limited.

[0014] Optionally, multiple storage boxes are fixedly installed on the support frame, and multiple three-proof fabrics are installed, with each three-proof fabric corresponding to a storage box. Each storage box has a rotating take-up roller, and each storage box has an opening. The three-proof fabric passes through the opening on the corresponding storage box and is wrapped around the take-up roller. A drive shaft is coaxially fixed on the take-up roller, and the drive shaft extends to the outside of the storage box.

[0015] By adopting the above technical solution, after the lifting frame moves closer to the support frame and retracts and folds, it drives the winding roller to rotate by rotating the drive shaft on each storage box, thereby winding the three-proof cloth into the storage box, thus effectively protecting the three-proof cloth and increasing its service life.

[0016] Optionally, the storage box has an inspection port on its side wall, a cover for closing the inspection port is provided on the storage box, a first fixing member for fixing the cover is provided on the storage box, the three-proof cloth is detachably mounted on the lifting frame, and a second fixing member for fixing the three-proof cloth is provided on the lifting frame.

[0017] By adopting the above technical solution, when the three-proof cloth is damaged, it can be replaced by opening the inspection port on the storage box and loosening the second fixing piece to detach the three-proof cloth from the lifting frame, thus increasing its practicality.

[0018] Optionally, the clamping assembly includes a fixed frame, a clamping frame, a top block, a wedge, and a limiting member. The fixed frame and the clamping frame are both fixedly mounted on the support frame, and a clamping area for clamping the crash barrier is formed between the fixed frame and the clamping frame. The top block is slidably mounted on the fixed frame in a direction close to or away from the clamping frame, and the top block is used to abut against the crash barrier. The wedge is slidably mounted on the fixed frame, and the wedge is used to insert into the gap between the fixed frame and the top block. The cross-sectional area of ​​the wedge gradually increases in a direction away from the top block. The limiting member is used to prevent the wedge from sliding.

[0019] By adopting the above technical solution, the support frame is erected on the crash barrier, and the crash barrier is located in the clamping area formed between the fixed frame and the clamping frame. The sliding wedge is inserted into the gap between the fixed frame and the top block, and as the wedge is inserted, it drives the top block to slide closer to the clamping frame, so that the clamping frame and the top block are respectively pressed against the two sides of the crash barrier. The limiting member prevents the wedge from sliding, thereby fixing the support frame to the crash barrier.

[0020] Optionally, an anti-slip pad is fixedly provided at one end of the clamping frame near the first reinforcing frame.

[0021] By adopting the above technical solution, the anti-slip pad increases the firmness of the clamp when it is fixed to the crash barrier.

[0022] Optionally, the baffle has an arc-shaped cross-section and is made of elastic steel.

[0023] By adopting the above technical solution, the baffle is squeezed and deformed when it comes into contact with the crash barrier, which increases the sealing performance when it is in contact with the crash barrier.

[0024] Optionally, a rotating shaft is rotatably provided at one end of the baffle near the protective plate. The axis of the rotating shaft is perpendicular to the sliding direction of the baffle. A sealing strip is sleeved on the rotating shaft. The sealing strip is cylindrical and is in rolling connection with the protective plate. A sealing plate is fixedly provided at one end of the baffle near the protective plate, and the sealing plate abuts against the sealing strip.

[0025] By adopting the above technical solution, the gap between the sealing strip and the baffle is sealed by the sealing plate, and the sealing strip is rolled to the protective plate, thereby increasing the sealing performance between the baffle and the protective plate.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The frame is erected at the construction location of the crash barrier. The frame is fixed to the crash barrier using clamping components. The construction area is formed by the protective plate, side plates, and top plate. Then, the baffle is slid by the drive component to seal and block the gap between the protective plate and the crash barrier. This effectively prevents the strong light generated by the construction work on the top of the crash barrier from interfering with the vision of vehicles on the road below, thereby greatly improving the safety of the construction work on the top of the crash barrier.

[0028] 2. The lifting frame is driven to rise by the drive component, providing a larger construction work space and improving practicality. After the lifting frame rises, the gap between the support frame and the lifting frame is covered and sealed by the three-proof cloth to ensure the protection effect.

[0029] 3. The gap between the sealing strip and the baffle is sealed by the sealing plate, and then the sealing strip is rolled to the protective plate to increase the sealing between the baffle and the protective plate. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0038] This application discloses a movable construction protection device for the top of an elevated crash barrier. (Refer to...) Figure 1 The system includes a frame 1, which includes a support frame 11 and a lifting frame 12. The lifting frame 12 is slidably mounted on the support frame 11 in a vertical direction. A protective plate 111 is fixedly mounted on the support frame 11. Side plates 112 are fixedly mounted on the support frame 11 and on both sides of the protective plate 111. An operating space is reserved on the side closer to the inner side of the elevated structure. A top plate 121 is fixedly mounted on the lifting frame 12. The protective plate 111, side plates 112 and top plate 121 are all made of galvanized steel. A construction area for construction operations is formed between the protective plate 111, the two side plates 112 and the top plate 121.

[0039] Reference Figure 2 , 3 The support frame 11 is provided with a clamping assembly 2 for fixing the support frame 11 to the crash barrier. The clamping assembly 2 includes a fixing frame 21, a clamping frame 22, a top block 23, a wedge block 24 and a limiting member. The fixing frame 21 and the clamping frame 22 are both fixedly installed on the support frame 11, and a clamping area for clamping the crash barrier is formed between the fixing frame 21 and the clamping frame 22. An anti-slip pad 221 is fixedly installed at the end of the clamping frame 22 near the first reinforcing frame. The anti-slip pad 221 is made of rubber, and the end of the anti-slip pad 221 that abuts against the crash barrier is provided with anti-slip texture.

[0040] Reference Figure 2 , 3Two top blocks 23 are slidably mounted on the fixed frame 21 along the direction of approaching or moving away from the clamping frame 22. The two top blocks 23 are located on opposite sides of the fixed frame 21. A connecting rod 231 is fixedly mounted on each top block 23. A through hole is formed on the fixed frame 21 along the sliding direction of the top block 23, and the connecting rod 231 slides through the through hole. An anti-detachment block is fixedly mounted on the connecting rod 231. Two sliding grooves are formed on the support frame 11, and a wedge 24 is slidably mounted in each groove. Each wedge 24 corresponds to one of the top blocks 23. The wedge 24 is used to insert into the gap between the fixed frame 21 and the top block 23, and the cross-sectional area of ​​the wedge 24 gradually increases along the direction away from the top block 23.

[0041] Reference Figure 3 The limiting component includes a limiting screw 25, with each wedge 24 corresponding to a limiting screw 25. The limiting screw 25 is rotatably mounted on the fixed frame 21, with one end of the limiting screw 25 extending into the slide groove. The axial direction of the limiting screw 25 is parallel to the sliding direction of the wedge 24. The limiting screw 25 is threadedly engaged with the corresponding wedge 24. A rotating handle 251 is coaxially fixed on the side of the limiting screw 25 outside the slide groove. The support frame 11 is mounted on the crash barrier, and the crash barrier is positioned within the clamping area formed between the fixed frame 21 and the clamping frame 22. By rotating the rotating handle 251, the wedge 24 is driven to slide through the limiting screw 25, allowing the wedge 24 to insert into the gap between the fixed frame 21 and the top block 23. As the wedge 24 is inserted, the top block 23 is driven to slide closer to the clamping frame 22, so that the clamping frame 22 and the top block 23 abut against the two sides of the crash barrier, thereby fixing the support frame 11 to the crash barrier.

[0042] Reference Figure 2 Multiple guide rods 122 are fixedly installed on the lifting frame 12. The guide rods 122 are vertically arranged. Three or more guide holes are opened on the support frame 11 along the vertical direction. The guide rods 122 correspond one-to-one with the guide holes, and the guide rods 122 slide through their respective guide holes.

[0043] Reference Figure 2 The support frame 11 is provided with a drive assembly 3 for driving the lifting frame 12 to rise and fall. The drive assembly 3 includes a screw sleeve 31 and a transmission screw 32. The screw sleeve 31 is rotatably mounted on the support frame 11 and its axis is vertical. The transmission screw 32 is fixedly mounted on the lifting frame 12 and its axis is vertical. The transmission screw 32 is adapted to the screw sleeve 31 and passes through the screw sleeve 31 and is threadedly engaged with the screw sleeve 31. The side wall of the screw sleeve 31 is provided with anti-slip texture.

[0044] Reference Figure 1 , 2Three storage boxes 4 are fixedly installed on the support frame 11. One storage box 4 corresponds to the protective plate 111, and the other two storage boxes 4 correspond to the two side plates 112 respectively. The storage box 4 corresponding to the protective plate 111 is located on the side of the protective plate 111 away from the construction area, and the two storage boxes 4 corresponding to the two side plates 112 are located on the side of the two side plates 112 that are close to each other.

[0045] Reference Figure 4 Each storage box 4 has a rotating take-up roller 41, and each storage box 4 has a three-proof cloth 42 wrapped around the take-up roller 41. Each storage box 4 has an opening on its side wall, through which the three-proof cloth 42 passes. One end of the take-up roller 41 is coaxially fixed with a drive shaft 43, which extends outside the storage box 4. The end of the drive shaft 43 outside the storage box 4 has a cross groove, and the process of the cross groove is compatible with the process standard of the bolt cutter.

[0046] Reference Figure 4 , 5 The storage box 4 has an inspection port 44 on its side wall. The storage box 4 is equipped with a cover plate 45, which is adapted to the inspection port 44. The storage box 4 is equipped with a first fixing member 46 for fixing the cover plate 45. The first fixing member 46 includes screws. The cover plate 45 is fixed to the storage box 4 by screws and closes the inspection port 44. The lifting frame 12 is equipped with a second fixing member 123 for fixing the three-proof cloth 42. The second fixing member 123 includes bolts. The lifting frame 12 is also equipped with a clamping plate 124. One end of the three-proof cloth 42 that extends out of the storage box 4 is clamped between the clamping plate 124 and the lifting frame 12. The clamping plate 124 is fixed to the lifting frame 12 by bolts, so that the three-proof cloth 42 can be fixed to the lifting frame 12.

[0047] Reference Figure 6 A baffle 113 is slidably installed vertically on the support frame 11 and on the side of the protective plate 111 near the storage area. The length of the baffle 113 is horizontal, and the cross section of the baffle 113 is arc-shaped. The baffle 113 is made of elastic steel, and the two sides of the baffle 113 abut against the two side plates 112 respectively.

[0048] Reference Figure 6The support frame 11 is equipped with a driving component for driving the baffle 113 to slide. The driving component includes two driving screws 114, which are respectively located on both sides of the baffle 113. Both driving screws 114 are rotatably connected to the support frame 11, and their axial directions are vertical. Connecting blocks 1131 are fixedly installed on both sides of the baffle 113. The two driving screws 114 correspond one-to-one with the two connecting blocks 1131 on the baffle 113, and the driving screws 114 and connecting blocks 1131 are threadedly engaged. By rotating the two driving screws 114, the baffle 113 is driven to slide on the support frame 11, so that the baffle 113 abuts against the top wall of the crash barrier. When the baffle 113 abuts against the crash barrier, it is squeezed and deformed by the driving force of the two driving screws 114 and sticks tightly to the top wall of the crash barrier.

[0049] Reference Figure 6 A rotating shaft 115 is rotatably mounted on one end of the baffle 113 near the protective plate 111. The axis of the rotating shaft 115 is horizontal and parallel to the axis of the protective plate 111. A sealing strip 1151 is fitted on the rotating shaft 115. The sealing strip 1151 is cylindrical and is in rolling connection with the protective plate 111. A sealing plate 1132 is fixedly mounted on one end of the baffle 113 near the protective plate 111. The sealing plate 1132 has a bent section, which is arc-shaped and abuts against the sealing strip 1151. The sealing plate 1132 seals the gap between the sealing strip 1151 and the baffle 113, and the sealing strip 1151 is in rolling connection with the protective plate 111, thereby increasing the sealing performance between the baffle 113 and the protective plate 111.

[0050] The implementation principle of a movable elevated crash barrier top construction protection device according to an embodiment of this application is as follows: A support frame 11 is erected on the crash barrier, with the crash barrier positioned within the clamping area formed between the fixed frame 21 and the clamping frame 22. Rotating the handle 251 causes the wedge block 24 to slide via the limiting screw 25, inserting it into the gap between the fixed frame 21 and the top block 23. As the wedge block 24 is inserted, the top block 23 slides closer to the clamping frame 22, causing the clamping frame 22 and the top block 23 to abut against both sides of the crash barrier, thus fixing the support frame 11 in place. The construction area for construction work is formed by the protective plate 111, the two side plates 112 and the top plate 121 on the crash barrier. Then, by rotating the two drive screws 114, the baffle 113 is driven to slide on the support frame 11, so that the baffle 113 abuts against the top wall of the crash barrier. When the baffle 113 abuts against the crash barrier, it is squeezed and deformed by the driving force of the two drive screws 114 and sticks tightly to the top wall of the crash barrier. This effectively avoids the strong light generated by the construction work on the top of the crash barrier from interfering with the vision of vehicles on the road below, thereby greatly improving the safety of the construction work on the top of the crash barrier.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
