Description

Technical Field

[0001] This utility model relates to the field of bridge construction, specifically a protective device for hanging basket construction. Background Technology

[0002] The hanging basket is a commonly used mobile work platform in bridge construction. It usually consists of a load-bearing frame and a support basket. It can move along the tracks on both sides or the bottom of the bridge beam. After a section of the bridge is completed, it can be moved as a whole to the next section to continue the work. It is widely used in the cantilever construction of long-span bridges.

[0003] The cantilever construction method involves first installing and securing the cantilever formwork on the already poured beam segment of the bridge. Then, reinforcing bars are tied inside the cantilever formwork, and formwork is erected. Next, concrete is poured to form a new beam segment. After the concrete reaches the design strength, the formwork is removed, the fixing device between the cantilever formwork and the beam is loosened, and the cantilever formwork is moved to the next construction position through a traction system. After being re-fixed, the above process is repeated, gradually advancing towards the mid-span of the bridge until the construction of the entire cantilever section of the bridge is completed.

[0004] Protective devices are often used during hanging basket construction. However, when faced with strong winds, the existing protective devices are directly blown by the wind, causing the entire hanging basket to sway. Therefore, a new protective device for hanging basket construction is proposed to address this problem. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A hanging basket construction protection device of this utility model includes a support frame; multiple sets of fixing rods are fixedly connected to the bottom end of the support frame; the fixing rods are arranged in an array at the bottom end of the support frame; a base is fixedly connected to the bottom end of the fixing rods; multiple sets of support rods are fixedly connected to the top end of the base; the support rods are arranged around the base; sliding rods are fixedly connected to the side walls of the support rods; flexible protective cloth is slidably connected to the side walls of the sliding rods; multiple sets of first bolts are threadedly connected to the side walls of the sliding rods; the multiple sets of flexible protective cloths on the sides of the support rods can form a surrounding protective barrier, blocking pollutants inside the base, reducing the spillage of pollutants during construction and preventing pollution of the surrounding environment. It also reduces damage to facilities below the support frame caused by falling debris, providing a safe and clean working environment for hanging basket construction. Pulling the flexible protective cloth along the sliding rods to the bottom end of the base reduces the overall wind-exposed area of ​​the protection device, reducing the impact of strong winds on the base device, reducing the impact of strong winds on the stability of the hanging basket due to the large stress area of ​​the protective structure, and ensuring construction safety in windy weather.

[0007] Preferably, a pair of first blocking rods are fixedly connected to the top of the base; a second bolt is threadedly connected to the side wall of the first blocking rod; a pair of second blocking rods are fixedly connected to the top of the base; the second bolt and the second blocking rod are positioned on both sides of the flexible protective cloth; the first and second blocking rods form a limiting position on both sides of the flexible protective cloth, and rotating the second bolt can push the second bolt towards the second blocking rod, firmly clamping the side wall of the flexible protective cloth between them, forming effective support for the middle of the flexible protective cloth, reducing the protective gaps caused by the sag of the flexible protective cloth, ensuring the integrity of the protective barrier, and preventing the spillage of construction pollutants.

[0008] Preferably, a pair of first fixing seats are fixedly connected to the side wall of the second blocking bar; a fixing pin is fixedly connected to the side wall of the first fixing seat; a warning sign is set in the middle of the first fixing seat; the pair of first fixing seats adopt an L-shaped design, which can form a ring-shaped support for the warning sign from both sides and the bottom, and fix it with the pin of the fixing pin, restricting the warning sign to the preset position. In the face of strong winds, it can also reduce the warning sign from falling off, and can also provide safety warnings to the surrounding area.

[0009] Preferably, a pair of pull ropes are fixedly connected to the side wall of the base; a second fixing seat is fixedly connected to the bottom end of the base; the second fixing seat is located on one side of the first blocking rod; by pulling the pull ropes to tie the flexible protective cloth, the shrunken flexible protective cloth can be firmly fixed to the bottom end of the base, reducing the loosening and displacement of the flexible protective cloth after shrinking.

[0010] Preferably, a plastic observation window is fixed to the inner wall of the flexible protective fabric; a covering layer is fixed to the side wall of the plastic observation window; the setting of the plastic observation window allows for clear observation of the surrounding working conditions through the flexible protective fabric during construction, while not affecting the protective function of the flexible protective fabric in blocking pollutants, thus improving the safety of the hanging basket construction.

[0011] Preferably, a crossbar is fixed to the top of the flexible protective fabric; the crossbar is slidably connected to a sliding rod; the slidable connection between the crossbar and the sliding rod provides an additional support point from the top of the flexible protective fabric, which, together with the double support of the first blocking rod in the middle, effectively reduces the swaying amplitude of the flexible protective fabric, ensuring that the flexible protective fabric remains vertically stable in the protective state, and reducing the swaying that causes the protective gap in the middle of the flexible protective fabric to expand.

[0012] The advantages of this utility model are:

[0013] 1. The hanging basket construction protection device described in this utility model can form a surrounding protective barrier through multiple sets of flexible protective cloths on the side of the support rod, blocking pollutants inside the base and reducing the spillage of pollutants during construction, thus reducing pollution of the surrounding environment. It can also reduce the damage to facilities below the support frame caused by falling debris, providing a safe and clean working environment for hanging basket construction. Pulling the flexible protective cloth along the slide rod to the bottom of the base reduces the overall wind-exposed area of ​​the protection device, which can reduce the impact of strong winds on the base device and reduce the impact of strong winds on the stability of the hanging basket due to the large stress area of ​​the protective structure, thus ensuring construction safety in windy weather.

[0014] 2. The hanging basket construction protection device of this utility model forms a limit by having a first blocking rod and a second blocking rod respectively located on both sides of the flexible protective cloth. By rotating the second bolt, the second bolt can be pushed towards the second blocking rod, firmly clamping the side wall of the flexible protective cloth between the two, forming effective support for the middle of the flexible protective cloth, reducing the protective gaps caused by the fall of the flexible protective cloth, ensuring the integrity of the protective barrier, and preventing the spillage of construction pollutants.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 5 As shown in the embodiment of this utility model, a hanging basket construction protection device includes a support frame 1; multiple sets of fixing rods 11 are fixedly connected to the bottom end of the support frame 1; the fixing rods 11 are arranged in an array at the bottom end of the support frame 1; a base 12 is fixedly connected to the bottom end of the fixing rods 11; multiple sets of support rods 13 are fixedly connected to the top end of the base 12; the support rods 13 are arranged around the base 12; sliding rods 14 are fixedly connected to the side walls of the support rods 13; flexible protective cloth 15 is slidably connected to the side walls of the sliding rods 14; multiple sets of first bolts 16 are threadedly connected to the side walls of the sliding rods 14; during operation, after the hanging basket is installed at the bottom of the base 12, the multiple sets of flexible protective cloth 15 on the side of the support rods 13 can block pollutants generated during construction inside the base 12. When there is strong wind, the wind will blow and contact the flexible protective cloth 15. At this time, the multiple sets of first bolts 16 can be rotated, and then a pulling force is applied to the flexible protective cloth 15, causing the flexible protective cloth 15 to slide on the side of the sliding rods 14, thereby blocking the multiple sets of support rods 13. The flexible protective cloth 15 descends to the bottom of the base 12, allowing the support frame 1 to retract when facing strong winds. During normal use, the flexible protective cloth 15 can be fixed in its original position to protect the hanging basket. The height of the flexible protective cloth 15 sliding along the side wall of the slide rod 14 can also be adjusted by rotating the first bolt 16. Multiple sets of flexible protective cloths 15 on the side of the support rod 13 form a surrounding protective barrier, blocking pollutants inside the base 12 and reducing pollution of the surrounding environment during construction. This also reduces damage to facilities below the support frame 1 caused by falling debris, providing a safe and clean working environment for the hanging basket construction. Pulling the flexible protective cloth 15 along the slide rod 14 to the bottom of the base 12 reduces the overall wind-exposed area of ​​the protective device, decreasing the impact of strong winds on the base 12 and reducing the impact of strong winds on the stability of the hanging basket due to the large stress area of ​​the protective structure, thus ensuring construction safety in windy weather.

[0025] like Figure 1 and Figure 3As shown, a pair of first blocking rods 2 are fixedly connected to the top of the base 12; second bolts 21 are threadedly connected to the side walls of the first blocking rods 2; a pair of second blocking rods 22 are fixedly connected to the top of the base 12; the second bolts 21 and the second blocking rods 22 are positioned on both sides of the flexible protective cloth 15; during operation, the first blocking rods 2 and the second blocking rods 22 cooperate to limit the flexible protective cloth 15 in the middle, so that the flexible protective cloth 15 is stable on the side of the base 12. By rotating the second bolts 21, the second bolts 21 can move towards the second blocking rods 22, and the second bolts 21 can move the flexible protective cloth 15 to the side. The wall is fixed between the first blocking rod 2 and the second blocking rod 22, so that the flexible protective cloth 15 will not fall due to the lack of fixation in the middle of the flexible protective cloth 15 during protection. The first blocking rod 2 and the second blocking rod 22 are respectively located on both sides of the flexible protective cloth 15 to form a limit. By rotating the second bolt 21, the second bolt 21 can be pushed to move closer to the second blocking rod 22, which firmly clamps the side wall of the flexible protective cloth 15 between the two, forming effective support for the middle of the flexible protective cloth 15, reducing the fall of the flexible protective cloth 15 and creating protective gaps, ensuring the integrity of the protective barrier and preventing the spillage of construction pollutants.

[0026] like Figures 1 to 2 As shown, a pair of first fixing seats 3 are fixedly connected to the side wall of the second blocking rod 22; a fixing pin 31 is fixedly connected to the side wall of the first fixing seat 3; a warning sign 32 is set in the middle of the first fixing seat 3; when the hanging basket is under construction, a warning sign needs to be hung. The warning sign 32 can be placed in the middle of the pair of first fixing seats 3, and then the fixing pin 31 can be inserted into the side wall of the first fixing seat 3 to fix the warning sign 32 as a whole. The L-shaped setting of the first fixing seat 3 can support and fix the bottom of the warning sign 32; by adopting the L-shaped design of the pair of first fixing seats 3, the warning sign 32 can be supported from both sides and the bottom. With the pin fixing of the fixing pin 31, the warning sign is restricted to the preset position. In the face of strong winds, the warning sign 32 can be reduced from falling off, and the surrounding area can also be given a safety warning.

[0027] like Figure 1 and Figure 3 As shown, a pair of pull ropes 4 are fixedly connected to the side wall of the base 12; a second fixing seat 41 is fixedly connected to the bottom end of the base 12; the second fixing seat 41 is located on one side of the first blocking rod 2; during operation, when the flexible protective cloth 15 shrinks in windy weather, a pulling force can be applied to the pull ropes 4, and then the pull ropes 4 are covered on the top of the flexible protective cloth 15, and then the pull ropes 4 are passed through the limiting hole of the second fixing seat 41, and the flexible protective cloth 15 is tied and fixed by pulling the pull ropes 4; by pulling the pull ropes 4 to tie the flexible protective cloth 15, the shrunken flexible protective cloth 15 can be firmly fixed to the bottom end of the base 12, reducing the loosening and displacement of the flexible protective cloth 15 after shrinking.

[0028] like Figures 3 to 4As shown, a plastic observation window 5 is fixed to the inner wall of the flexible protective fabric 15; a covering layer 51 is fixed to the side wall of the plastic observation window 5; during operation, the surrounding working conditions can be observed through the plastic observation window 5 through the flexible protective fabric 15, and the covering layer 51 can cover the plastic observation window 5; the setting of the plastic observation window 5 allows for clear observation of the surrounding working conditions through the flexible protective fabric 15 during construction, while not affecting the protective function of the flexible protective fabric 15 in blocking pollutants, thus improving the safety of the hanging basket construction.

[0029] like Figure 4 As shown, a crossbar 6 is fixedly connected to the top of the flexible protective fabric 15; the crossbar 6 is slidably connected to the slide bar 14; during operation, the crossbar 6 at the top of the flexible protective fabric 15 can provide support during protection, and cooperates with the first blocking bar 2 to make the flexible protective fabric 15 stable during protection; through the slidable connection between the crossbar 6 and the slide bar 14, an additional support point can be provided from the top of the flexible protective fabric 15, which, together with the double support of the first blocking bar 2 in the middle, effectively reduces the swaying amplitude of the flexible protective fabric 15, ensuring that the flexible protective fabric 15 remains vertically stable in the protective state, and reducing the expansion of the protective gap in the middle of the flexible protective fabric 15 due to swaying.

[0030] Working principle: After the hanging basket is installed at the bottom of the base 12, the multiple sets of flexible protective cloths 15 on the side of the support rod 13 can block pollutants generated during construction on the base 12. When strong winds occur, the wind will blow and contact the flexible protective cloths 15. At this time, the multiple sets of first bolts 16 can be rotated, and then a pulling force is applied to the flexible protective cloths 15, causing the flexible protective cloths 15 to slide on the side of the sliding rod 14, lowering the multiple sets of flexible protective cloths 15 as a whole to the bottom of the base 12, so that the support frame 1 as a whole faces the wind. The protective device is retractable. During normal use, the flexible protective cloth 15 can be fixed in its original position to protect the hanging basket. The height of the flexible protective cloth 15 sliding on the side wall of the sliding rod 14 can also be adjusted. Then, rotating the first bolt 16 adjusts the height of the flexible protective cloth 15. The first and second blocking rods 22 work together to limit the middle section of the flexible protective cloth 15, stabilizing it on the side of the base 12. Rotating the second bolt 21 moves it towards the second blocking rod 22, fixing the side wall of the flexible protective cloth 15 between the first and second blocking rods 22. This prevents the flexible protective cloth 15 from sagging due to the lack of fixation in the middle. During construction, a warning sign needs to be hung on the hanging basket. The warning sign 32 can be placed in the middle of a pair of first fixing seats 3. Then, the fixing pin 31 is inserted into the side wall of the first fixing seat 3 to fix the warning sign 32. The L-shaped design of the first fixing seat 3 supports and fixes the bottom of the warning sign 32. When the flexible protective cloth 15 encounters a large... After the wind dies down, tension can be applied to the pull rope 4. Then, the pull rope 4 is placed over the top of the flexible protective cloth 15. The pull rope 4 is then passed through the limiting hole of the second fixing seat 41. The flexible protective cloth 15 is secured by tightening the pull rope 4. During construction, the hanging basket can be used to observe the surrounding work conditions through the plastic observation window 5. The covering layer 51 can cover the plastic observation window 5. The crossbar 6 at the top of the flexible protective cloth 15 can provide support during protection. Together with the first blocking bar 2, it makes the flexible protective cloth 15 stable during protection.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
